Yasir F. Muhsin, Ayad K. Khan, Shaker M. Alwan
Bacterial infections have a large effect on public health. Some bacterias are innately resistant to certain classes of antibiotics, either because they lack the target or are impermeable to the drug. Others are innately susceptible but develop resistance by one of a growing variety of mechanisms. Synthesis of new derivatives of cephalexin that may have improved antibacterial, broader spectrum of activities, resistance against certain β-lactamases and/or pharmacokinetic properties. These derivatives include the incorporation of certain dipeptides at the amino group of cephalexin molecule. The dipeptides to be used are: valine-boc-tryptophan, alanine-boc-tryptophan, valine- boc-histidine, alanine-boc-histidine. The incorporation of dipeptide moiety on the acyl side chain very close to β-lactam ring may widen the spectrum of activity. This chemical addition act as isosteric group to the alkoximino that protect Beta lactam ring from bacterial beta lactamase enzyme. These new derivatives were successfully synthesized with reasonable yields show some resistance against β-lactamases and improve the pharmacokinetic properties. This approach may give new life for old drugs namely, cephalosporins and penicillins that contain amino group at the acyl side chain close to β-lactam ring. The chemical structures of these derivatives were confirmed by infrared (IR), proton nuclear magnetic resonance (HNMR) spectroscopy and elemental analyses, molecular docking, swiss ADME software.

This study has implications for physical pharmacy, medical, and biochemistry due to its use of surface chemistry. This paper describes how drug-adherent hydrogels and their pH levels influence drug adsorption on Poly (vinyl pyrrolidone-acryl amide) Hydrogel Surface. The adsorption phenomenon was examined as a function of temperature (5, 15, 25, and 37.5oC). The temperature of the solution increased adsorption of cephalexin. H2O on the surface has increased as the temperature increased, the adsorption uptake of cephalexin.H2O increased on hydrogel (endothermic adsorption). Basic thermodynamic functions for the adsorption process were calculated and used for the interpretation of the results. Using the Freundlich and Temkin models, the results show that the drug had full applicability for adsorption on hydrogel. The adsorption isotherms have an S-shaped configuration, which was determined by Giles’ classification. Freundlich isotherm n-value was found to be 2.057, meaning good adsorption.

Background: Hypertension (HT) and type 2 diabetes mellitus (T2DM) are the most prevalent chronic disease in the Iraqi population, leading to increasing heart disease, kidney problem, and coronary artery disease or atherosclerosis. One of the famous cause of the chronic diseases like hypertension and T2DM is obesity. Resistin (RETN) is a principle hormone link between obesity and Type2 Diabetes Mellitus (T2DM) because it induces insulin resistance. It is one member of cysteine-rich secretory proteins family. A putative receptor for RETN is TLR-4, it is conceder immunomodulators of the immune response. Immune responses participate in arterial hypertension. A case-control study was conducted to estimate the relation between serum Toll-like receptor 4 (TLR4) level and serum resistin (RETN) levels with angiotensin converting enzyme (ACE) activity in patients with hypertensive subjects and hypertensive patients with T2DM. We also studied the effect of angiotensin converting enzyme inhibitor (captopril 50 mg) on Resistin and TLR-4 levels in hypertensive subjects with type 2 diabetes mellitus. Objectives: Study the effect of ACE activity on serum level of RETN and TLR-4 and their association between the Resistin hormone and its receptor in hypertensive subjects with or without T2DM subjects, and study the effect of Angiotensin Converting Enzyme Inhibitory on serum level of RETN and Toll-like receptor4 (TLR4) in hypertensive subjects with T2DM using captopril 50 mg treatment. Materials and Method: A case-control study was conducted from September 2019 to July 2020 at the Department of Chemistry and Biochemistry, College of Medicine in Al-Nahrain University on 90 subjects classified into three groups; each group consists of 30 patients. Study subjects ages will be matched in all three groups and their gender (Men) Age range was between (40–48) years old. This group consists of 30 patients with hypertension, 30 hypertensive patients with T2DM and 30 hypertensive patients with T2DM using captopril drug. For all the subjects in the research serum RETN and TLR-4 were estimated by using enzyme-linked immunoassay (ELISA) technique. Also ACE were estimation by using a spectrophotometric assay. Results: Serum resistin and its receptor TLR-4 were higher in hypertensive patients with T2DM subject than in hypertensive patients. In addition, serum Angiotensin Converting Enzyme (ACE) activity was higher in hypertensive patients with T2DM subject than in hypertensive patients. Furthermore, a positive correlation was found between TLR4 and resistance in hypertensive patients with T2DM subject group. Conclusion: The Results indicated that ACE inhibitor (captopril) decreases the serum levels of Resistin and TLR-4 in hypertensive subjects with T2DM. Moreover, evaluation the serum level of ACE activity, RETN, and TLR4 in all studies groups.

Objective: This study utilizes C60 fullerene to prepare a new carrier (Buckysomes) for pemetrexed (for the first time) and investigate the contribution of such conjugates on the behavior, release, and anticancer activity against lung cancer cells through cell line study. Methods: fullerene C60 was synthesized by laser irradiation of polycyclic hydrocarbons (PAHs) and loaded with pemetrexed (PMX). The pemetrexed loaded on fullerene C60 was evaluated by fourier transform infrared spectroscopy (FTIR), power x-Ray diffraction (PXRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), differential scanning calorimetry (DSC), particle size analyzer, and zeta potential. The percentage of drug loading, in vitro release, and anticancer activity against lung cells A549 were also evaluated. Results: Characterization technique showed the successful loading of pemetrexed on fullerene C60 nanocarrier, S9 was the optimum sample with percentage of yield reach to 90.17. Release profile shows that the percentage release of pemetrexed after 240 minutes equal 40% from pure PMX, while the release after 240 minutes was found to be 55% from pemetrexed loaded fullerene C60 nanocarrier, it is reached to 91.7% for pemetrexed loaded on fullerene nanocarrier versus 72% for pemetrexed at the end of 24 hours release. pemetrexed loaded on fullerene nanocarrier (S9) shows lower IC50 (1.03 μM) and higher cytotoxic effect than that of pure PMX (3.1 μM) and blank fullerene (75.5 μM) on A549 cancer cell at different times of exposure (24, 48, and 72 hours). The anticancer activity of pemetrexed against lung cancer cells A549 was improved upon loading on fullerene nanocarrier (80% cell death for S9) in comparison with the free drug (60% cell death) at 24 hours, although the fullerene showed limited anticancer activity (20% cell death after 24 hours) indicating that the loading process led to improve the cytotoxic activity of the drug for the tumor cells. Pemetrexed loaded on fullerene nanocarrier (S9) at 24 hours shows a higher percentage of cell death (52%) than the native pemetrexed (35%), this could be attributed to the synergistic effect of fullerene on the cytotoxic effect of pemetrexed in its complex (S9) which may lead to faster onset of action Conclusion: This work succeeded to prepare Buckysomes for pemetrexed using fullerene C60 that may act as a promising nanocarrier for pemetrexed since it produced enhancement of anticancer activity, solubility and release profile.

Haneen A. I., Neihaya H. Z., Ali Alhammar
Bacillus spp. can produce a wide range of metabolites with important biological activities and extensively used in many applications. About 40 soil samples were collected from different gardens in Baghdad city, and only 52 bacterial isolates were identified. Thirty-eight (73.1 %) of isolates were Bacillus spp. which were: Bacillus cereus (21; 55.3%), Bacillus subtilis (11; 28.9%), and Bacillus amyloliquefaciens (6; 15.8%). B1 and B16 isolates belong to B. cereus and B. subtilis, respectively, were selected to perform the subsequent tests. Biofilm formation varied among the tested pathogenic bacteria. Fourier transform infrared spectroscopy (FTIR) analysis of B1 and B16 ethyl acetate extracts showed functional groups of secondary metabolites with major peaks belong to COOH, C-H, O-H CO-N, and N-H stretches. While, gas chromatography–mass spectrometry (GC-MS) analysis of B1 and B16 extracts revealed multiple active compounds (cyclopentan, hexane, phenol, 2,2-methylenebis, L-proline, propanoic acid, oxalic acid-isobutyl pentyl ester, pyrrolo pyridazine and octadecenoic acid). Interestingly, B16 and B1 extracts showed high activity against Staphylococcus aureus and S. pyogens, and moderate activity against Klebsiella spp., Escherichia coli, and Serratia marcescens with no effect on Pseudomonas aeruginosa. Antibiofilm activity of B16 and B1 extracts showed high inhibition against Streptococcus pyogenes and moderate on S. aureus, E. coli and K. spp., while low effect on S. marcescs and no effect on P. aeruginosa. Anticancer activity was also observed by exposing ethyl acetate extract, produced by B1 and B16 against breast cancer cell line MCF7 at different concentrations.

Haitham M. Kadhim, Ahmed M. T. Al Mosawi
Pulmonary fibrosis (PF) is a chronic, progressive illness associated with poor prognosis and morbidity, defined by an abnormal buildup of fibrotic tissue in the lungs parenchyma. The current study aims to assess the invivo emodin and salvianolic acid antifibrotic activity on lung fibrosis. Forty mice were divided into five groups; The first group is composed of eight healthy mice to be a negative control group, while the remaining thirty-two mice had received 1-mL/kg intraperitoneal carbon tetrachloride (CCl4) twice weekly for six weeks. Then, eight of these mice were sacrificed to be a positive control group, while the remaining twenty-four mice were divided into three groups, the first group received six every other day intraperitoneal doses of emodin 40 mg/kg and the second group received silymarin 20 mg/kg while the third group received salvianolic acid by the same route. Mice lungs were taken and examined histopathologically to assess the antifibrotic effects. Fibrosis is reduced significantly in histopathologic sections in the emodin and salvianolic acid groups. Antifibrotic effects of emodin can be due to nuclear factor-ĸb lowering, decrease of epithelial mesenchymal transition, TGF-ß1 Smad signaling suppression, Toll-like receptor-4 (TLR-4) pathway inhibition, and hematopoietic stem cells (HSCs) inhibition. The antifibrotic effects of Salvianolic acid can be due natural killer cells activation, nuclear factor erythriod-derived 2-like 2 up-regulation, transforming growth factor-β1 inhibition. Both agents (Emodin and salvianolic acid) have a comparable antifibrotic activity to that of silymarin, alleviating lung fibrosis.

Manal A. Aziz, Abdulkareem. S. Diab, Wafaa. H. Al-Hussainni
Background: Increased serum uric acid (SUA) level is associated with joint damage and has been positively correlated with various diseases such as chronic kidney diseases (CKD) due to inflammation. This study aimed to investigate the relationship between hyperuricemia (increased SUA) and inflammatory status in Iraqi people with different stages of CKD. Methods: A cross-sectional study recruited 128 participants with CKD (45 stage I, 42 stages II and, 41 stage III CKD patients) and 88 age-and sex-matched healthy controls. SUA, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), blood urea, serum creatinine, cholesterol, triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and very-low-density lipoprotein (VLDL) levels were determined and compared between the groups. Results: The stage III disease group had significantly higher values of SUA, TNF-α, IL-6, creatinine, triglyceride, and blood urea levels (p < 0.0001), as well as HDL (p < 0.001), and VLDL (p < 0.05) in comparison to the controls. No significant differences in serum cholesterol, LDL, and IL-10 were found between the stages I, II and III CKD patients and controls. Conclusion: This study found CKD (stage III) patients had higher SUA. Hyperuricemia is a potential risk factor for CKD progression. These findings propose that SUA may play a critical role in inflammatory status in stage III CKD patients.

Omar S. Salih, Mowafaq M. Ghareeb
Objective: A major concern about multi-site targeting is whether or not the nasal cavity is a viable route for delivering a broad range of medicines, from tiny molecules to biological macromolecules. Ciprofloxacin hydrochloride is a crystalline powder that is almost colorless. Slightly soluble in water with amphoteric properties in the form of a pKa of 6.09 for carboxylic acid and 8.8 for nitrogen on the piperazinyl ring, and the drug is 2.5% and has a pH of 3 to 4. In situ gel is a polymer solution in liquid form when applied to the mucosa. Once the solution is applied to the mucosa, it is transformed into a semisolid gel phase. Methods: Seven were developed for various parameters for assessment. Results: At physiological temperature, the gelation time for F1 and F5 was not achievable with gelation time for F3 and F4. With F3 and F7, a more tightly packed gel structure was found with the organization in a lattice pattern. Formulations containing Pluronics and chitosan demonstrated greater strength than formulations with chitosan/ethylcellulose or chitosan/chitosan ratio, which had the ethylcellulose/chitosan ratio as well as other factors in common. The interaction of chitosan with Pluronics may result in a greater molecular weight of hydrophobic molecules. It was discovered that the formulations’ medication release percentage was 71 to 91% in the first eight hours. After seven hours, the total percentage of medication permeated through the sheep nasal membrane was 78%. Conclusion: The improved formulation consisted of F3 and F7, both of which were safe for regular nasal administration, with the additional benefit of possessing required mucoadhesive strength and a temperature of 34°C for phase transition.

Samah K. Yahya, Shahlaa M. Salih, Yasir W. Issa
Background: Behçet disease (BD) is a long-lasting systemic inflammatory disease considered through repeated cutaneous, ocular, and urogenital ulcers, vascular, gastrointestinal, neurovascular, and arthritic participation. Immune checkpoints are membrane molecules regulators of immune activation in usual biological conditions, preserving homeostasis of the immune system and preventing auto-immunity as CD28 and CTLA4. The study’s goal was to clarify the correlation between CD28 genetic polymorphisms in Iraqi patients and BD susceptibility and the impact of genetic polymorphism on soluble CD28 in Behçet’s. Methods: A case-control study on 50 BD patients with 40 controls was conducted to determine the correlation between CD28 gene polymorphisms (rs3116496 C/T) using primers specific probe and RT-PCR amplification and estimation serum level of soluble CD28 by ELISA technique. Results: The BD patients showed an elevated level of soluble CD28. The odds ratio and confidence interval (CI) 95% CI for the CC was 1.83 (0.80–4.21), TC was 0.52 (0.22–1.20), and TT genotypes was 1.21 (0.20–7.47) respectively with no significant differences between patients and controls in genotype and allele frequencies of rs3116496 SNP (p > 0.05). Conclusions: Higher levels of soluble CD28 support their role as positive T-cell regulator molecules and therapeutic target. Genetic polymorphisms in CD28 showed no association with BD. To support these results, additional cases should be investigated in further studies.

Maysoon I. Ahmed, Ali S. Ismail
This paper describes the synthesis and characterization of sustainable polymers using β-myrcene monomer as a terpene compound. These polymers were synthesized using an environmentally benign emulsion copolymerization method, three monomers were used: isodecyl methacrylate, isobutyl methacrylate, and cyclohexyl methacrylate, each of which was polymerized separately with β-myrcene monomer. All these polymers can be vulcanized latex, which can be used to make semi-synthetic rubber. Ammonium persulfate was used as an initiator, sodium dodecyl sulfate SDS as an emulsion, and sodium bicarbonate as a pH regulator to synthesis the copolymers in a 50/50 ratio. Fourier transform infrared (FTIR), proton nuclear magnetic resonance (1H-NMR) and carbon-13 nuclear magnetic resonance (13CNMR) spectroscopy were used to characterize the synthesized copolymers, the spectra results indicated that their signals correspond to the chemical formula of the copolymer. The glass transition temperature means that the polymer is rubbery in nature, and the glass transition temperature values are similar to those of homogeneous methacrylate polymers, it was discovered that the length of the side chain of methacrylate monomers affects the polymerization reaction, and the optimum conditions for this reaction are 60°C for 20 hours.

34. Density Functional Theory and Docking Studies of Schiff Base Complexes of Thiazole
Hasan S. Mohammed
We optimized and determined frontier orbitals, highest occupied molecular orbital (HOMO), and lowest unoccupied molecular orbital (LUMO) energy) of Schiff base of thiazole (L) and its complexes of Cu(II) and Zn(II). Calculations were carried out using density functional theory (DFT) for thiazole (L) and its complexes with 6 to 31G* and LanL2DZ basis sets, respectively. The gap energy between HOMO and LUMO was small for the complexes and higher for Schiff base of thiazole (L). This means the Schiff base of thiazole is more stable than complexes Since the docking studies on coordination compounds are rare, we studied Schiff base of thiazole ligand and its copper and zinc ions complexes. We used Molegro virtual docker (MVD) software to predict the inhibition activity of thiazole and its complexes against 2MUJ in plasmodium falciparum. These molecules exhibited a MolDock score of (-272.1 to -397.1) kcal/mole and a re-rank score in (-91.4 to -198.1) kcal/mole. All studied molecules exhibit good docking results, but the best one is the copper complex.

Sarah S. Hasson, Ibrahim S. Abbas, Bahir A. R. Mshimesh
Campsis grandiflora (Bignoniaceae) is a fast-growing deciduous climber, native to central and southern China. The dried flowers have been used as a carminative, blood tonic, and febrifuge in Chinese traditional medicine. This plant has an anti-inflammatory, anti-oxidant, anti-depressant, and anti-bacterial effect, beneficial in stagnant blood and endometriosis. In this study, the detection of lupeol and acetoside was performed using thin layer chromatography (TLC) and high-performance liquid chromatography (HPLC); while the isolation done by preparative layer and column chromatography using hexane and butanol extract of Iraqi C. grandiflora flowers. Spectral analysis by Fourier-transform infrared spectroscopy (FTIR) and Nuclear magnetic resonance (NMR) was done for the two isolated phytochemicals. Furthermore, the anti-inflammatory activity of total ethanolic extract and one of the isolated compounds (acetoside) was assessed using an egg-albumin induced acute inflammation and formalin-induced subacute and chronic inflammation within mice model, compared with diclofenac. The results showed that the hexane and butanol extract of Iraqi C. grandiflora flowers contain lupeol and acetoside, respectively, and from our knowledge, this is the first novel study that suggested the presence of lupeol in the C. grandiflora flowers extract. Moreover, the total extract of this plant possesses a moderate anti-inflammatory activity against the acute inflammatory model and an excellent anti-inflammatory activity against the subacute and chronic inflammatory models. In conclusion, the anti-inflammatory effect of Iraqi C. grandiflora total extract attributed partly to caffeic acid derivatives, i.e., acetoside, and other phytochemicals such as terpenoids produce an additive or synergistic effect with acetoside.

Purpose: To study the cocrystal formation between dextromethorphan HBr and a selected conformer, tartaric acid, as a method of improving the physicochemical properties especially the solubility of dextromethorphan HBr which was selected as a model drug. Methods: Different methods were used to prepare cocrystals of dextromethorphan HBr such as co-grinding; liquid assisted grinding, and solvent evaporation methods at different molar ratio (1:1, 1:2 and 1:3). Characterization of the prepared formulation was done using saturation solubility, drug content, Fourier transform-infrared (FTIR) spectroscopy, differential scanning calorimeter (DSC), In vitro dissolution study, Powder X-ray diffraction (PXRD), and scanning electron microscopy (SEM). Results: Saturation solubility study revealed an increase in the solubility of drug dextromethorphan HBr, especially in F9 prepared by the solvent evaporation method. FTIR studies confirm the formation of hydrogen bonds in the selected formula, F9, with a noticeable shift in the vibration bands. Thermal analyses by DSC demonstrated the formation of new species, a cocrystal having melting points that is different from its components. The formation of cocrystals was also confirmed by PXRD denoting the crystallinity of formed cocrystals through the observation of new intense peaks with 2θ value difference. The formulations containing the prepared cocrystals showed an improvement in the dissolution rate with marked enhancement in the drug solubility. Also, SEM analyses exhibited micrographical variation typical to cocrystals, suggesting the generation of a new solid phase. Conclusion: The study showed that the described solvent evaporation method can be used as a simple method to prepare cocrystals at molar ratio 1:3 to enhance the solubility of sparingly soluble drug represented by dextromethorphan HBr.

The widespread of resistance to antibacterial agents that became threatening made it essential to search for new antibacterial agents with new mechanisms of action. Different amino acids, dipeptides, and polypeptides derivatives were synthesized and tried as antibacterial agents, some of which were found to possess antibacterial activity. Five derivatives were prepared, the Ethyl-Para amino benzoate, ethyl 4-(phenylsulfonamido) benzoate, N-(4-(hydrazinecarbonyl) phenyl) benzene and N-(4-(2-(4-(dimethylamino) benbenzylidene) hydrazine carbonyl) phephenyl) benzene. The methods used for the identification of synthesized derivatives include elemental analysis, thin layer chromatography, infrared spectroscopy and melting point determination. The Preliminary study of antimicrobial activity for the target compounds showed that the compounds (4 and 5) had no activity against Staphylococcus aureus, while showed moderate activity against Escherichia coli, when compared to Ciprofloxacin. These compounds are thus promising targets for further research in the antibacterial wide field.

Nada S. Mohammed, Entesar H. Ali
Chloramphenicol acetyltransferase (CATs) is a bacterial enzyme that detoxifies the antibiotic chloramphenicol and is implicated in bacterial chloramphenicol resistance. The acetyl group from acetyl-CoA is covalently bound to chloramphenicol by this enzyme, preventing chloramphenicol from binding to ribosomes. In this study, Pseudomonas aeruginosa was harvested to study its chloramphenicol acetyltransferase. P. aeruginosa was isolated from urinary tract infections and diagnosed morphologically, microscopically, and with VITEK 2 system. Then we examined the ability of bacteria to produce chloramphenicol acetyltransferase; initially was tested for resistance to the antibiotic chloramphenicol, and then cultured in the production media difco nutrient broth (supplemented with 1% of glycerol and addition of the substrate chloramphenicol) which was suitable for growing bacterial cells and extraction of the enzyme. Chloramphenicol acetyltransferase was extracted by ultra-sonication and then purified through precipitation with ammonium sulfate as a first purification step, ion-exchange chromatography, and gel filtration. The activity of the enzyme was measured for each purification step. Purification of chloramphenicol acetyltransferase from P. aeruginosa using ammonium sulfate revealed that the specific activity was 20 units/mg protein, and the best saturation ratio was 40%, the purification times were 1.5, and the enzymatic yield was 88.8%. Furthermore, the results of enzyme purification by using ionic exchange DEAE-Cellulose were: the specific activity was 47.5 unit/mg protein, the enzymatic yield was 88.6%, and the number of purification times was 3.7. The purification results using gel filtration Sephadex G-100 showed that the specific activity was 66.6 unit/mg protein, purification times, and enzymatic yield were 5.2 and 66%, respectively.

56. Effects of Vaginal Sildenafil Citrate on Ovarian Blood Flow and Endometrial Thickness in Infertile Women Undergoing Intra-uterine Insemination
Muntaha A. Abdullah, Wassan A. Abdulhamed, Muayad S. Abood
Background: Healthy blood circulation in the uterus and ovaries can affect the success of assisted reproductive therapy (ART). Ovarian Color Doppler and ultrasound blood flow assessment is a useful non-invasive technique that assesses ovarian vascular function by evaluating the ovarian stromal blood’s resistance index and pulsatility index. The resistance index is a sign of resistance to blood circulation. The lower the resistance index value, the more blood circulation. The use of vaginal sildenafil is a promising treatment to improve endometrial circulation and ovarian Doppler blood flow index to treat infertile women. Objective: To evaluate the effect of vaginal sildenafil citrate on ovarian blood flow and measured by two-dimensional Doppler ultrasound parameters (ovarian stromal blood resistance index and pulsatility index) and pregnancy of infertile women receiving termination of the intra-uterine insemination (IUI). Subjects and Methods: A total of 50 infertile patients achieved IUI and were randomly divided into two groups, the sildenafil group, of which 25 patients were included in this study and received treatment with Sildenafil citrate 50 mg (group of sildenafil) and. The second group, 25 infertile women, did not receive sildenafil (group without sildenafil). Both groups of infertile women received letrozole to stimulate intrauterine insemination was followed by continuous transvaginal ultrasound to assess the number and size of mature follicles, the thickness of the endometrium, and the ovarian stromal blood flow to measure the resistance index (IR) and the pulsatility index (PI) of the dominant ovary. Results: Patients in the sildenafil group showed (significantly) more mature follicles than the non-sildenafil group (p = 0.028). The mean endometrial thickness in the sildenafil group was also greater than the days of the human trophozoite. The group of without sildenafil was (8.90 ± 0.54 mm and 8.0 ± 0.91 mm) respectively and p = 0.001, and also had significantly lower resistance index and pulsatility index (p < 0.001) (0.41 ± 0.08 vs 0.58 ± 0.07) and (0.46 ± 0.08 vs 0.63 ± 0.07), respectively. The pregnancy rate in the sildenafil group was significantly higher than in the non-sildenafil group (p = 0.032). Conclusion: Topical sildenafil treatment significantly improved ovarian interstitial blood flow, endometrial thickness, and pregnancy rate.

Khalid K. Shaker, Haider A. Mehdi
A new ligand (LH) and its complexes with Cu (II) and Co (II) were prepared. The purity of the new synthesized compound was checked by performing TLC using appropriate solvent and the spots visualized in the UV light. Ligand (LH) is characterized by using Fourier-transform infrared spectroscopy (FTIR), ultraviolet-visible (UV-vis), Proton nuclear magnetic resonance (1H-NMR) spectra, and Mass spectrum. Metal ion complexes with Cu (II) and Co (II) were prepared in a M:L (1:1) ratio and characterized by the same spectrophotometric techniques, magnetic susceptibility and molar conductivity. The new ligand showed a reasonable amount of anti-corrosion activity. It was observed that the corrosion rate (CR) in the presence of the inhibitor decreased with the increase of the inhibitor concentration at a constant temperature.

58. The Effect of Carbamazepine on Interictal Epileptic Discharges in Patients with Focal Epilepsy
Mazin M. Hammady, Shaymaa J. Mohammed, Omar S. Sabbar
Background: According to the International League Against Epilepsy (ILAE) recommendations, carbamazepine (CBZ) is considered at the top of the first-line antiepileptic drugs in treating partial epileptic paroxysms with or without secondary generalization. The CBZ act on cortical neurons by different types of actions, electroencephalographic (EEG) examination of patients placed on CBZ therapy is of special importance due to this ability of medication, the administration of CBZ and its derivative should be scheduled concerning the form of epilepsy, specificity of individual EEG, EEG dynamics and clinical manifestation during the treatment. Objective: This study aimed to evaluate the impact of carbamazepine on interictal epileptic discharge for patients with focal epilepsy. Patients and Method: This is a prospective study conducted in Basra general hospital from first of March to first of November 2014, one hundred ten (110) patients recently diagnosed as having partial epilepsy were included in the study. Their age range from 15 to 45 years, no one of them had a history of encephalitis, meningitis, head trauma or cerebrovascular accident (CVA), with normal neurological exam and normal MRI and CT scan. All patients were exposed to EEG exam at the starting of the study by using digital EEG machine according to the 10 to 20 International system. All EEG records that presented with changes suggestive of interictal epileptic discharges (IEDs) were then independently reviewed. The frequency of IED was calculated. Patients began the drug therapy with carbamazepine (20 mg/kg/day), and a second EEG exam was done after six months. Patients who show no compliance to treatment or resistance to treatment (continue to experience clinical attacks of seizure) were excluded. All patients who missed their follow-up visits after three months of starting a treatment or did not attend the second EEG exam appointment after six months of treatment were excluded. Results: From one hundred ten patients included in the study only 77 patients continued the study and 33 patients were excluded. The results revealed that 68 patients (88.3%) had a significant reduction in mean epileptic discharge in the second EEG exam after six months of treatment with carbamazepine. Furthermore, among them, 42 patients (61.8%) had no more clinical seizure attacks during study time, and 26 patients (38.2%) continued having seizure attacks until the end of third month after starting treatment, and most of them experienced one attack during the first or second month. Conclusion: Carbamazepine is still a very effective drug in the management of partial epilepsy. Besides, EEG is an essential tool in the assessment of patient’s response to carbamazepine and reduction in interictal epileptic discharges on subsequent EEG studies may predict the chance of developing further clinical epileptic attacks in patients with partial epilepsy using carbamazepine drug.

59. Immuno Histochemical Expression of CD133 as Cancer Stem Cells Marker in a Sample of Iraqi Patients with Colorectal Carcinoma
Adyan K. Majee, Zahraa K. Zaidan, Waleed H. Yousif, Majid H. Al-Dari
Colorectal cancer is one of the most frequent malignancies in the world, and it is also one of the most deadly. Distant metastases and recurrence frequently cause patient death. Cancer stem cells (CSCs) play a crucial role in colorectal cancer spread and relapse. CSCs are a type of cancer cell that can self-renew, divide indefinitely, and differentiate in multiple directions. The CD44, CD133, CD24, EpCAM, LGR5, and ALDH are some cell surface markers used to identify colorectal CSCs. They are highly tumorigenic, chemoresistant, and radioresistant, making them important in colorectal cancer metastasis and recurrence as well as disease-free survival. The current study included 60 Iraqi male patients. They were assigned into three groups. Group I consisted of 20 newly diagnosed colorectal cancer patients, group II consisted of 20 relapsed patients who were treated with chemotherapy and were cured, but the tumor relapsed, and group III consisted of 20 patients who demonstrated resistance to chemotherapy treatment. All clinicopathological markers were analyzed, and they demonstrated a higher tumor grade in group II compared to the other groups and a difference in age between groups. In comparison to group I, CD133 expression was higher in groups II and III, with the observation that some IHC slides were clear of typical colorectal cancer cells but positive for CD133, indicating the presence of cancer stem cells. In the resistance group, similar effects were reported. The results could be explained by the fact that the highest expression of CD133 suggests a significant number of cancer stem cells, which play a key role in tumor relapse and treatment resistance. As a result of these findings, CD133 may be employed as a biomarker for cancer stem cells, allowing for their detection and aiding in the process of tailoring therapy for these cells within the tumor mass, preventing tumor relapse and resistance to chemotherapy.

Third group rats with only left ovary were removed, fourth group rats both ovaries were removed, fifth group rats with both ovaries were removed and treated (intramuscular injection) with (10 mg/kg) estrogen. The results show a significant increase (p < 0.05) in several inflammatory cells and levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), malonedialdehyied (MDA) with significant (p < 0.05) reduce in glutathione (GSH) levels in third and fourth group compare with healthy female rats. While, after using estrogen in treatment, the outcomes exhibited non-statistic significant (p < 0.05) differences in a number of inflammatory cells, liver enzymes, MDA, and GSH compared with healthy female rats. It was concluded that estrogen has been an important role in the treatment of myocardial damages caused by ischemia.

62. Anti-Cancer Efficacy of 6 Mercaptopurine Loaded Biotinylated Cellulose Nanowhiskers
Osamah N. Wennas, Mohammed H. Mohammed, Dhulfiqar Ali Abed
6 Mercaptopurine (6 MP) is an important drug used for cancer treatment. However, 6 mercaptopurine has many disadvantages including low water solubility, limited and variable bioavailability, and severe side effects. This work’s objective was to optimize the delivery of 6 MP by targeting it to the solid cancer tissues using an endogenous receptor system and glutathione-sensitive α, β unsaturated linker. Two 6 MP prodrugs were prepared, cellulose nanowhiskers (CNW) were used as a nanocarrier for the preparation of 6 MP-CNW-biotin (compound 12), using glutathione (GSH) sensitive linkage between the CNW and 6 mercaptopurine. The second prodrug, 6 MP-biotin (compound 9), was prepared by conjugating 6 mercaptopurine to the biotin directly using glutathione sensitive linker to evaluate the CNW role. The release assay was done in-vitro and it showed that just 11.4% of 6 mercaptopurine was released from compound 12 under glutathione at the micromolar concentration (100 μM), while the accumulative release reached 78.2% under 10 mM glutathione concentration. The in vitro cytotoxic effect was evaluated by 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT) assay, the results showed that compound 9 has a greater inhibitory effect on cell lines with biotin overexpression (HepG2 and MCF-7) and low inhibitory effect on biotin negative cell line (CHO). Compound 12 showed activity comparable to 6 mercaptopurine against HepG2 and MCF-7, and lower inhibitory effect on CHO.

Doaa S. Aleqabi, Huda I. Al-Qadhi
Background: Infertility is defined as the inability to become pregnant after one year of non-contraceptive sexual activity. Letrozole, a potent, non-steroidal selective, reversible aromatase inhibitor, is considered an established treatment for ovulation induction. Tamoxifen citrate (TMX) is a triphenylethylene derivative with a structure similar to CC that has been considered for ovulation dysfunction treatment. If the female has good quality of follicles in her ovaries and no other reasons for infertility, treatment with these medications can result in conception. Objectives: This study aimed to compare the effectiveness of tamoxifen and letrozole in ovulation induction outcomes in infertile Iraqi women. Patients and Methods: This prospective randomized study was carried out from November 2020 to March 2021 on 88 infertile women, selected randomly from the infertile center in Alkut Hospital for Maternity and Childhood. The patients were divided into two groups viz. the first group (48 patients) received letrozole 2.5 mg twice daily from day 3 of the cycle for 5 days for three cycles, and the second group (40 patients) received tamoxifen 20 mg twice daily from day 2 for 5 days for three cycles. Results: The current study shows a statistically significant difference between both groups regarding the endometrial thickness, which was significantly higher in the tamoxifen group than the letrozole group. No significant difference was reported between both groups as regarding pregnancy rate, rate of miscarriage, Mean number of mature follicles ≥ 18 mm, and follicular diameter. Conclusion: Both letrozole and TMX were effective ovulation induction agents, TMX was superior to letrozole in achieving a higher Endometrial thickness.

65. Role of Quercetin Flavonoid as Antidiabetic: A Review
Hussein K. Hamid, Maithm A. Obaid
Today hypoglycemia, kidney problem and hepatotoxicity became the main complication of diabetes mellitus (DM) and real challenges to modern medical research. New trials afford the use of herbal products obtained from plant sources considered more affordable and effective and show less adverse effects as an alternative cure for DM. Natural products like secondary metabolites have many different biological activities and attention is received to developing an anti-diabetic medication from a flavonoid compound. Numerous studies have highlighted not only the flavonoids have hypoglycemics effects, but it’s also important in managing DM complications. DM and its numerous complications are now becoming one of the serious threats to human health and also, the current available synthetic drugs used for the management of DM are neither cheap nor entirely effective. Unfortunately, these current drugs do not restore regular glucose homeostasis over a prolonged period and they are not free from side effects. Quercetin shows a good anti-oxidant activity and may improve beta-cell functions and increase insulin secretion from the Langerhans islets in pancreas, which can be considered a good alternative medical treatment for diabetic patients. The present review is an attempt to understand the biological activity, therapeutic activity and mechanism of quercetin and its eventual clinical results in field of medicine development in the diabetes mellitus management as an alternative treatment.

Biotechnology, such as its application in medication, is commonly used during our everyday lives. Implementing nanomaterials (NMs), atoms, binding energies, and compounds existing within different compounds are easy to analyze and modify. Nanotechnology is being used as nano dentistry throughout the dental field. The chemical, physical and biological dimensions of iron oxide nanoparticles are taken as selecting a nanoparticle to be used in nano dentistry. To build the functional organizational structure, different atoms or molecules are also inserted. In dentistry advances or evaluation, iron oxide nanoparticles (IONPs)have been used. Including dental disease prevention medications, prostheses, and that for teeth implantation, iron oxide nanoparticles have been used. Also, iron oxide nanoparticles supply dental fluids or medications, avoid, and cure some dental problems (oral cancer), and sustain medical care to a significant level. Throughout the dental field, the whole review summarizes the use of iron oxide nanoparticles.

67. Advance Nanogels of Drug Delivery System: A Review
Ahmed Y. Fadhel, Nawal A Rajab
The term ‘nanogels’ defined as particles in nanosized made cross-linked polymers networks by chemically or physically which is a swell in a suitable solvent. The nanogels are made up of various forms of synthetic or natural polymers that are bound together by physical non-covalent bonds such as H-bonds, electrostatic bonds, and hydrophobic bonds or by chemical covalent bond. A nanosize of nanogel is designed to reduce some of the disadvantages of micron size particles, which includ retention at targeting site, surface area, site specificity, swelling properties, loading efficiency of drug, and finally release behavior. It classifies based on responsive behavior and on the basis of linkages (physical and chemical). This review aims to provide general introduction on nanogels, their novel application in different approach and recent synthesis methodology.

68. Study of Main Factors Affecting the Leakage of Aluminum into the Food Wrapped in Aluminum Foil During Cooking
Mohammed A. Hussein, Khalid W. S. Al-Janabi
Different cooking conditions were examined for aluminum content in food cooked while wrapped with aluminum foil. The influence of each anticipated factor (the acidity of the cooking medium, type of acids normally used in cuisines namely acetic and tartaric acids, various cooking temperatures, influence of the presence of sodium chloride salt, the effect of cooking oil, and the length of time of cooking) was studied thoroughly as a function of aluminum degraded out of the aluminum foils to the medium. The experimental samples were digested with nitric acid upon fulfillment of examining each factor separately before quantifying aluminum with the sensitive technique of atomic absorption spectroscopy. The outcomes of the study have shown that the increment in the acidity and the heat of the cooking medium have exhibited a very noticeable effect on the Aluminum content leaked out of the aluminum foil. Nevertheless, the cooking time, the presence of the salt of sodium chloride, and the oil medium compared to the aqueous have exhibited a positive influence by increasing the aluminum leakage out of the foil into the solution.

Marwan S. Ibrahim, Mohammed M. Mohammed
Background: Asthma is a significant cause of morbidity and mortality worldwide. Asthma, a chronic respiratory disease characterized by chronic airway inflammation, bronchial hyper-responsiveness, and reversible airflow obstruction, poses a substantial economic burden on patients and caregivers alike. Education is a critical component in the management of asthma. Objective: This study is designed to assess the impact of pharmacist-led educational interventions on asthma control and serum levels of inflammatory and oxidative stress biomarkers. Method: Patients in this study received conventional therapy for chronic bronchial asthma, in addition to pharmaceutical care and patient education by clinical pharmacists for three months. All patients enrolled in this study were assessed clinically for asthma control test (ACT) and biochemically; serum levels of Interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), and SOD-3 at the baseline and after 3 months. Result: At the end of the study, patients who received a pharmaceutical care plan significantly improved their asthma control by improving the asthma control test score and significant changes in IL-6, TNF-alpha, and SOD-3 levels (p < 0.05) after 3 months of follow up by a pharmacist. Conclusion: The present study results provide supportive evidence concerning pharmacists’ favorable effects on asthma patient care and support pharmacists as valuable health care team members.
