Abstract: في هذه الدراسة ، تم استخدم ايبوكسيي زيت النخيل EPO كملدن للبولي بوتيلين سكسينيت باستخدام الكلوروفورم كمذيب ، تم خلط ستة اوزان من PSPE وقد استخدم جهاز FTIR الطيفي لتحديد المجاميع الفعالة . كما وتم قياس الاستقرارية الحرارية والتحلل البيولوجي ، والخصائص المورفولوجية للخليط بواسطة جهاز التحليل الحراري الوزني TGA ، المجهر الالكتروني الماسح SEM وتقنية FTIR ، حيث اظهرت النتائج بان هناك بعض التاثر بين المركبين بوجود الاواصر الهيدروجينية التي تربط بين نهايات المجاميع الفعالة للبوليمر OH وبين حلقة الايبوكسي . مزيج الـ PSPE اظهر استقرار حراري عالي وتحسن في الخواص البيولوجية مقارنة مع الـ PBS النقي . كما اظهرت النتائج المورفولوجية للخليط ان EPO كان ذو قابلية امتزاجية جيدة مع PBS. تم تعديل قطب الكربون الزجاجي GCE مع طبقه رقيقة من (PSEP ) باستخدام طريقة محلول التبخر لانتاج القطب الجديد المعدل . PSEP/GC تم ايضا دراسة عمليات الاكسدة والاختزال لسداسي سيانيد الحديدات (II) باستخدام الـCyclic Voltammetry . وقد تبين ان ذروة الفصل ΔEpa - c ) ) بين قمم الاكسدة لايون فروسيانيد في محلول مائي هو 120 ملي فولت ، ونسبة التيار لقمم الاكسدة، IPA / IPC، كانت 1.6 لـ PSEP / GCE، مؤشرا انعكاسية وقابلية توصيلية جيدة للقطب المعدل. وبالتالي، فانه يمكن استخدامها لتحليل الجهد الكهروكيميائي . الخواص الفيزيائية للقطب المعدل PSEP / GCE تمثلت بالصلابة الجيدة، التصاق العالي على الاسطح المعدنية للقطب الالكتروليت الجامع ، بالاضافة الى الذوبانية والاستقرارية الجيدة للـPSEP على .GCE ايضا، الحساسية في ظل ظروف الـ cyclic voltammetry تعتمد بشكل كبير على تراكيز مختلفة من فروسيانيد ، الالكتروليت المستخدم ومعدل المسح . وقد لوحظ خلال معدلات مسح مختلفة بان قمم الاكسدة والاختزال للحديد / (III) الحديد (II) تمت بعملية معكوسة. | In this study, epoxidized palm oil (EPO) was utilized as a blended for poly butylene succinate (PBS) using chloroform as a solvent by solution casting process at six weight of PSEP. Fourier - transform infrared (FTIR) spectroscopy was used to identify the functional groups of PBS and PSEP blends. Thermal stability, biodegradable, and morphological properties of the blends were investigated by thermo gravimetric analyzer (TGA), and scanning electron microscope (SEM) technique. The FTIR spectra indicate that there are some molecular interactions by intra molecular hydrogen bond between PBS and EPO. All sets of PSEP blends show high thermal stability and significant improvement of biodegradable properties compared to pure PBS. Morphological results of PSEP blends show that EPO was good miscible with PBS. Aglassy carbon electrode (GCE) was modified with a poly butylene succinate - epoxidized palm oil (PSEP) film using a solution evaporation method to produce a new modified electrode PSEP/GCE. The redox process of K4[Fe(CN)6] during cyclic voltammetry was studied using the PSEP/GCE. It was found that the peak separation (∆Epa - c) between the redox peaks of ferrous cyanide ion in an aqueous solution is 120 mV and the current ratio of redox peaks, (Ipa/Ipc), is 1.6 for the PSEP /GCE, indicating good reversibility with good conductivity of the modified electrode. Hence, it can be used for voltammetric analysis. The physical properties of the modified electrode PSEP/GCE include good hardness, high adhesion to the metal surfaces of electrode collectors, solubility and good stability of the PSEP on GCE. Also, the sensitivity under conditions of cyclic voltammetry is significantly dependent on different concentrations of ferrous cyanide , the electrolyte used and the scan rate. At different scan rates, oxidation - reduction peaks of Fe(III)/Fe(II) were observed in a reversible process

Abstract: The present study was conducted to verify the relevance of lipids and lipoproteins levels and their byproduct of oxidation, malondialdehyde (MDA) in acne patients. The design of the project included one hundred acne patients (47% males and 53% females)and 40 apparently healthy individuals (control group). Total serum cholesterol (TC), high density lipoprotein cholesterol (HDL - C), triglycerides (TG), low density lipoprotein (LDL - C), very low density lipoprotein (VLDL - C) and MDA levels were measured in acne patients and the control group.The results indicated significant (P≤0.05) elevations for TC, TG, LDL - C, VLDL - C and MDA levels in acne patients with respect to those of the control group. Sex differences were obtained as rises forTC, LDL - C and MDA (P≤0.05) in males when compared with thoseof the females. The linear regression analysis exhibited significantpositive correlation for TC (r = 0.68, P≤0.05) and LDL - C (r = 0.48, P≤0.05) with ages of the control group but not in the acne patients.Smoker acne patients demonstrated significant elevations for TC, TG, VLDL - C, LDL - C and MDA (P≤0.05) in comparison with those of the control group, while nonsmokers acne patients showed significant elevations for TC and LDL - C (P≤0.05) during a comparable evaluation. Married acne patients indicated significant increases for TC, TG, VLDL - C, LDL - C and MDA (P≤0.05) when compared with those of the control group, while non married acne patients illustrated significant elevations for TG, VLDL - C, LDL - C and MDA (P≤0.05). The influence of treatment was studied, the data stated significant elevation for TG and LDL (P≤0.05), in treated acne patients when compared with those of the control group, while untreated acne patients showed significant increases for TC, TG, VLDL - C, LDL - C and MDA (P≤0.05) in comparison with those of the control group.These results suggested that oxidative stress is involved in the pathogenesis of acne. We believed that this study is the first to deal with changes of serum lipid profile and oxidative stress in acne patients.

Abstract: The present study aims at investigating the relationship b etween oxidative stress and hyperlipideamia in diabetes mellitus. For this purpose,(120) diabetes patients were chosen (48 type1 patients and 72 type2 patients). This sample of (120) patients was compared with a group of (50) healthy subjects. The malondialdehyde (MDA) (one of the markers of oxidative stress), serum total cholesterol(S.TC),triglycerides (S.TG) high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol(LDL) and very low density lipoprotein triglycerides (VLDL) were all measured via the enzymatic methods. Results indicated a significant increase(p<0.05) in the levels of (MDA),(S.TC),(S.TG),(HDL),(LDL) and (VLDL) in diabetes patients of both types, as compared with healthy subjects. The same fact holds when comparing the two types of patients. A significant increase (p<0.05) was also observed in the levels of (MDA),(S.TC),(S.TG),(HDL),(LDL) and (VLDL) in male and female diabetes patients of type1 as compared with healthy subjects. As for type2 patients the increase in the same values was(p<0.01) as compared with healthy subjects. The comparison of male and female patients showed a significant increase(p<0.05) in the levels of (S.TC),and (VLDL) only in type1. It was also found that age is an influential factor in the criteria of serum lipids and (MDA) levels in patients of both types, except in case of(S.TG)and(VLDL) in type2 patients where age proved irrelevant. Moreover, results indicated that (BMI) has an impact on (MDA),(S.TC),(S.TG),(LDL) and (VLDL) levels. The duration of the disease in patients of both types also produced a significant increase(p=0.05) in (MDA) levels and serum lipids criteria. The complications suffered by the patients because of diabetes also produced a significant increase (p<0.05 - p<0.005) in (MDA) levels and serum lipids criteria as compared with those free of such complications for both types. No significant correlation was found between MDA level and levels of serum lipids in all patients and in both types except(VLDL) in type2. All these results prove the correlative relationship between oxidative stress and serum lipids criteria in diabetes mellitus.
