Western blot analysis confirmed the scFv band size. Significant neutralization in the presence of scFv 1 and scFv 2 were obtained. Real time PCR revealed significant decrease in viral copy number. Conclusion Two specific neutralizing scFvs against two highly conserved neutralizing epitopes of the influenza A virus HA glycoprotein were selected. A strong neutralization effect of scFv1, showed the potential of this antibody for H3N2 influenza A controlling in the viral spread.Background Dextran is a commercially available bacterial exopolysaccharide (EPS) with several industrial applications in the food industry and in the biomedical industry as an adjuvant, emulsifier, carrier, and stabilizer. The production of dextran at the industrial level occurs through the fermentation of a sucrose-rich medium. Research to optimize dextran production has found that the yield of dextran varies depending the specific conditions for production. The aim of this study was to produce dextran and establish the optimal conditions for dextran biosynthesis from different Lactobacillus species isolated from healthy vaginal and infant stool samples. Methods Lactobacillus spp. were isolated and identified from vaginal and infant stool samples via the VITEK 2 system. The presence of dextran biosynthesis from the different Lactobacillus spp. BGB 15025 concentration isolates was determined by a screening test for mucoid colonies and confirmed via the ethanol precipitation method. To optimize for the maximum yield of dextran, the effects of various parameters such as temperature, incubation time, pH, inoculum size, aeration, and sucrose concentration were examined. Results All Lactobacillus spp. isolates were able to produce dextran. The optimal conditions for dextran production was at 24 hours of incubation at 30 °C with 15% sucrose, 4% inoculation size at pH 7.0 in aerobic conditions. This yielded a dextran dry weight of 580 mg/100 mL. Conclusion Dextran production from Lactobacillus species isolates vagina and infant stool had the ability to produce dextran.Background Neuroprotective mechanisms triggered by peroxisome proliferator-activated receptor-gamma agonist pioglitazone (PIO) and glucagon-like peptide 1 analog exendin-4 (Ex-4) in neurological diseases were reported, but whether mitochondrial biogenesis is involved or not in their neuro-protective mechanisms in type 1 Diabetes Mellitus (T1DM); has not been studied before. To bridge this gap, we investigated the effect of PIO and Ex-4 on brain mitochondrial biogenesis in streptozotocin- induced diabetes in rats. Methods Seven weeks after induction of diabetes in rats, serum fasting glucose and insulin were measured in studied groups. The brain was removed for histological analysis and assessment of mitochondrial complexes I and II, ATP, H2O2, brain derived neurotrophic factor (BDNF), cytochrome c and hemeoxygenase (HO)-1 activity, and relative gene expression of the nuclear factor; Nrf2 and the apoptotic markers bax & bcl2 and mitochondrial biogenesis markers; peroxisome proliferator-activated receptor γ coactivator (PGC) 1-α and sirtuin 1 (SIRT-1) and AMP-activated protein kinase (AMPK) and c-Jun-N-terminal kinase (JNK) proteins. Results Brain in untreated rats showed neurodegeneration area and significantly rising H2O2 and JNK, up-regulation of bax, down-regulation of bcl2. These changes were paralleled with significant reduction in Nrf2, HO-1, BDNF, complex I, II and ATP and SIRT-1/ PGC1-α expression. PIO and Ex-4 significantly improved the reported changes. Combined modality showed better improvement relative to each drug alone. Conclusion PIO and Ex-4 may have neuroprotective effects in T1DM, via targeting altered mitochondrial biogenesis probably due to modulation of brain SIRT-1 signaling, improvement of oxidative stress and equilibrating the balance between pro-apoptotic and anti-apoptotic mediators.Background Gastric cancer is still the main health threat being the third leading cause of deaths from cancers in the world. The major risk behind the gastric cancer is that it remains asymptomatic in the early stages and in (97%) cases it metastasizes to other organs. Gastric cancer is a multifactorial disease in which Helicobacter pylori (H. pylori) has been known as a risk factor. However, patients with gastritis, especially atrophic gastritis and gastric ulcer have been shown to be at an increased risk for developing gastric cancer. Methods This study included measuring the serum levels of E-Cadherin protein, carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) in 30 patients diagnosed with gastritis, 20 gastric ulcer patients, 20 gastric cancer patients and in 20 healthy volunteers serving as the control group. Results Infection with H. pylori was diagnosed by serology (IgA and IgG antibodies) as well as by rapid urease test (RUT) and histology. The results showed that 50 (71.4%) of the patients were positive for H. pylori. Levels of E-Cadherin were increased significantly in all patients in comparison to the control group with a large significant increase in the gastric cancer group. The levels of E-Cadherin were also significantly increased in H. pylori infected patients compared to H. pylori negative patients. A non-significant difference in the levels of CA19-9 and CEA was observed in all patients in comparison to healthy controls. Conclusion This study concluded that serum E-Cadherin could be considered as a potential marker in diagnosis of gastric cancer.Background In recent years, prostate cancer prevails as one of the lead cancers affecting men. Currently, prostate cancer research involves the phytochemical study of plants with anti-tumour effects. This study compares the anti-tumour effects of three plant species indigenous to Iran and their interaction with cluster of differentiation (CD)-82 protein, a therapeutic target found in prostate cancer cells. Methods The extracts of Hypericum perforatum, Achillea millefolium, and Aloe vera were prepared and their toxicological, cellular and gene expression responses were evaluated in PC-3 human prostate cancer cells and normal human chondrocyte cell line C28/I2. They were exposed to different concentrations of the plants (10 mg/mL, 5 mg/mL, 1 mg/mL, 100 µg/mL, 10 µg/mL, and 1 µg/mL) at three exposure time points (24, 48, 72 hours) to determine cancer cell cytotoxicity and gene expression profiles. Results Half-maximal inhibitory concentration (IC50) in PC-3 cells ranged from 0.6 to 8.5 mg/mL for H. perforatum extract, from 0.
