Abstract
INTRODUCTION The aim of this study was to compare the effect of five types of PEGlated nanoliposomes (PNLs) on α-synuclein (α-syn) fibrillization, attenuation of microglial activation, and silence of the SNCA gene, which encodes α-syn. METHODS To evaluate the inhibition of α-syn fibrillization, we used standard in vitro assay based on Thioflavin T (ThT) fluorescence. Next, to evaluate the attenuation of microglial activation, the concentration of TNF-a and IL-6 was quantified by ELISA assay in BV2 microglia cells treated with 100nM A53T α-syn and PNLs. In order to determine the silencing of the SNCA, real-time PCR and Western blot analysis was used. Finally, the efficacy of PNLs was confirmed in a transgenic mouse model expressing human α-syn. RESULTS ThT assay showed both PNL1 and PNL2 significantly inhibited a-syn fibrillization. ELISA test also showed the production of TNF-a and IL-6 was significantly attenuated when microglial cells treated with PNL1 or PNL2. We also found that SNCA gene, at both mRNA and protein levels, was significantly silenced when BV2 microglia cells were treated with PNL1 or PNL2. Importantly, the efficacy of PNL1 and PNL2 was finally confirmed in vivo in a transgenic mouse model. CONCLUSIONS In conclusion, the novel multifunctional nanoliposomes tested in our study inhibit α-syn fibrillization, attenuate microglial activation, and silence SNCA gene. Our findings suggest the therapeutic potential of PNL1 and PNL2 for treating synucleinopathies.

Abstract
Objectives: In this study, we aimed to identify putative biomarkers for identification and characterization of these cells in liver cancer.
Methods: We employed a supervised machine learning method, XGBoost, to data from 13 GEO data series to classify samples using gene expression data.
Results. Across the 376 samples (129 CSCs and 247 non-CSCs cases), XGBoost displayed high performance in the classification of data. XGBoost feature importance scores and SHAP (Shapley Additive explanation) values were used for the interpretation of results and analysis of individual gene importance. We confirmed that expression levels of a 10-gene set (PTGER3, AURKB, C15orf40, IDI2, OR8D1, NACA2, SERPINB6, L1CAM, SMC1A, and RASGRF1) were predictive. The results showed that these 10 genes can detect CSCs robustly with accuracy, sensitivity, and specificity of 97 %, 100 %, and 95 %, respectively.
Conclusions. We suggest that the ten-gene set may be used as a biomarker set for detecting and characterizing CSCs using gene expression data.

Abstract
BACKGROUND AND PURPOSE Breast cancer is one of the most common cancers and leading causes of death in the women worldwide. The evidence shows efficacy of apatinib against breast cancer. Accordingly, the present study was conducted to investigate the effect of apatinib on apoptosis, cell cycle, and Mitogen‑Activated Protein Kinase (MAPK) and nuclear factor-κB (NF-κB) signaling pathways in the breast cancer MDA-MB-231 cell line. METHODS The effects of apatinib on viability, morphology, tumor spheroid, cell cycle, migration, invasion, and apoptosis of MDA-MB-231 breast cancer cells were evaluated in vitro. In addition, expression of proteins involved in NF-κB and MAPK signaling pathways was evaluated using the western blotting analysis. RESULTS Apatinib decreased viability, tumor spheroid, migration, and invasion of MDA-MB-231 cells. Furthermore, apatinib altered morphology and regulated cell cycle which followed by apoptosis induction in MDA-MB-231 cells. Apatinib decreased expression of p-p65 and p65 proteins in NF-κB signaling pathways and increased expression of p38, p-p38, JNK, and p-JNK in MAPK signaling pathways. CONCLUSION The results suggested that apatinib can inhibit proliferation, migration and invasion of breast cancer cell line MDA-MB-231 through inducing apoptosis, cell cycle arrest, and regulating NF-κB and MAPK signaling pathways.

Abstract
OBJECTIVE In beta thalassemic patients, tissue damage occurs due to oxidative stress and it happens because of the accumulation of iron in the body. This study was conducted to determine the effect of zinc and vitamin E supplementation on antioxidant status in beta-thalassemic major patients. METHODS This double blind randomized clinical trial was carried out on 120 beta thalassemic patients older than 18 years. Patients were randomly categorized in four groups. Zinc (50mg/day) and vitamin E (400mg/day) supplements were administered for former and latter group, respectively. In the third group both supplements were administered in similar doses. The fourth (control) group received no supplement. The effect of supplementations on serum zinc and vitamin E, superoxide dismutase (SOD), glutathione peroxidase (GPX), total antioxidant capacity (TAC) and body mass index (BMI) were measured at the beginning and the end of the study. FINDINGS Serum zinc levels in group 1 and 3 were significantly increased (P<0.007 and P<0.005, respectively). Serum vitamin E levels in group 2 and 3 were also increased significantly (P<0.001). Mean GPX activity in group1, 2 and 3 decreased significantly (P<0.015, P<0.032 and P<0.029, respectively). Mean SOD activity and TAC did not show significant change after supplementation. BMI had significant increase in all treated groups (P<0.001). CONCLUSION Our results suggest that beta thalassemic patients have enhanced oxidative stress and administration of selective antioxidants may preclude oxidative damage.

Abstract
This study was performed to estimate prevalence of transaminase levels in type 2 diabetic patients and identify contributing risk factors. In this cross-sectional study 348 patients with type 2 diabetes, who attended the diabetic clinic of Yazd Diabetes Research Center, were studied from October 2004 to December 2005. Patients with history of viral hepatitis, alcohol abuse and use of drug such as Amiodarone, Bleomycin, methotrexate, tamoxifen and sodium valporate was excluded. To examine the relationships between ALT, AST in individuals with type II diabetes and relation to various metabolic parameters like triglyceride, cholesterol, age, duration of diabetes, gender and BMI. Of 348 patients that entered the study, mean age was 58.8 +/- 11.5. Elevated ALT and AST were found in 10.4 and 3.3% of type 2 diabetic patients, respectively. Although the prevalence of elevated ALT increased with increasing age, FBS and triglyceride levels in subjects, but it was not statistically significant. There was a significant association between elevated ALT and gender as well as diabetes duration. The prevalence of elevated of ALT in type 2 diabetic patients is 1.6 times higher than general population in Iran unrelated to age, BMI, glycemic control, triglyceride levels. Identification risk factors and mechanisms of these elevations are very important and require further evaluation.

Abstract
PURPOSE To study the 4 years incidence of diabetic retinopathy in patients with type II diabetes and effective factors on its progression. METHODS Among diabetic patients referred to Yazd Diabetes Research Center, 120 patients with type II diabetes without diabetic retinopathy were selected. After complete ophthalmic examination, fasting blood sugar (FBS), postprandial blood sugar, triglyceride, and cholesterol were measured and height, weight, and blood pressure (BP) were recorded. Then patients were followed with eye examination yearly for 4 years. RESULTS Four-year cumulative incidence of diabetic retinopathy was 47.5% (95% CI: 38.6-56.4). The retinopathy was mild nonproliferative diabetic retinopathy (NPDR) in 43 (35.8%) whereas 10 (8.3%) patients had moderate NPDR, 3 (2.5%) patients had severe NPDR, and only one patient had proliferative diabetic retinopathy. The incidence of diabetic retinopathy was 5.8% in first year, 20.3% in the second year, 24.4% in the third year, and 7.4% in the fourth year. Duration of diabetes, FBS, and systolic BP had statistically significant relation with grades of diabetic retinopathy. However, there was no significant association between age, sex, body mass index, triglyceride, cholesterol, method of treatment, smoking, and diastolic BP with grades of diabetic retinopathy. CONCLUSIONS These data provide 4-year cumulative incidence of diabetic retinopathy in defined type 2 diabetic patients. The present study shows that duration of diabetes, hyperglycemia, and systolic BP appear to be the major factors associated with the development of any level of retinopathy in type 2 diabetic patients.

Abstract
SETTING Afghanistan. OBJECTIVE To describe the results of rapid expansion of the DOTS strategy in a post-conflict environment, with a focus on the experience of the Rural Expansion of Afghanistan's Community-based Healthcare (REACH) Program. RESULTS Despite the destruction of the National Tuberculosis Program (NTP) and basic health services by war and an uncertain security situation, the NTP, with assistance from many partners and REACH, increased the number of patients receiving DOTS by 136% in 4 years (from 9261 cases in 2001 to 21851 in 2005), with an 86% treatment success rate. By focusing on rapidly expanding the number of facilities capable of providing tuberculosis (TB) diagnostic and treatment services and involving community health workers in case detection, referrals and home-based DOTS, REACH showed a 10-fold rise in the number of facilities providing TB services and a 380% increase in the number of sputum smear-positive pulmonary TB cases detected in 2 years (from 251/month in 2004 to 818/month in 2006) in 13 provinces. CONCLUSION At the current rate of expansion, case detection and successful treatment of TB cases in Afghanistan will continue to expand rapidly. The NTP and REACH have demonstrated that expansion of TB services in Afghanistan is possible despite the challenges.
