ABSTRACT Background: Obesity is a major risk factor for the onset of insulin resistance and type 2 diabetes mellitus (T2DM) caused by chronic inflammation of the islets of langerhans. Sleeve gastrectomy (SG) procedure increases particular hormone which stimulates insulin sensitivity. Mesenchymal stem cells (MSCs) can also exhibit potential immunomodulatory properties through their paracrine effects, however the mechanism regarding combination of them could not be adequately explained.  Aim: In this study, we explore the potential of sleeve gastrectomy followed by injection of MSCs in type 2 diabetic rats with obesity in improving insulin resistance. Methods: This study used a pre and post control group design with 18 rats that divided into 3 groups: control (C), sleeve gastrectomy (SG), sleeve gastrectomy + MSCs (SG+M). On day 10, the level of IL-6, IL-10 and HOMA-IR were evaluated using ELISA. Results:  This study showed a significant decrease of IL-6 level in all treatment groups on day 10, in which SG+M group showed optimum inhibition. This result was in line with the optimum increase of IL-10 in SG+M group. Moreover, our study also revealed the optimum decrease of HOMA-IR in SG+M group on day 10. Conclusion: Combination of SG and MSCs can optimally improve insulin resistance by modulating proinflammatory milieu though inhibiting IL-6 level and upregulating IL-10 level in obese type 2 diabetes mellitus rat model.

The social function of Islamic banking is an essential factor in the existence of Islamic banking, and research is still lacking. This study aims to analyze the trend of the social function of Islamic banking, its reporting conformity with accounting standards, and its effect on the financial performance of Islamic banking. The population of this study is Islamic Commercial Banks (ICB) registered with the Financial Services Authority (FSA) from 2014-2019. The sampling technique used purposive sampling and obtained 59 samples. The method of analysis used descriptive analysis and multiple linear regressions. The results show that fines and non-halal income still dominate the social function instrument. Social functions such as zakat, infaq, alms, and waqf tend to be low. Social reports in the form of sources and uses of zakat funds are sufficient. Reports on sources and uses of benevolent funds are also in the sufficient category, but the percentage value is lower. Internal zakat positively affects the performance of Islamic banking as measured by Return on Assets (ROA) and Operating Expenses on Operating Income (BOPO). Other variables do not affect the performance of Islamic banking as measured by ROA, BOPO, and Non-Performing Financing (NPF). This research theoretically confirms that internal zakat can encourage the growth of Islamic banking. Islamic banking must pay attention to social functions, especially zakat, an order from Islam.

Background: Diabetes mellitus is one of the health problems that is growing rapidly today. In Asia, majority of the population are non-obese with Type 2 Diabetes Mellitus (T2DM). Two main defects of T2DM, insulin resistance and impaired insulin secretion due to reduced pancreatic β cells. Persistent metabolic stress due to hyperglycemic conditions, causes inflammation of the islets of Langerhans. Interleukin-1β (IL-1β) signaling is the most frequent pathway inducing β cell dysfunction. The bariatric Sleeve Gastrectomy (SG) procedure increases particular hormone which stimulates β cell growth and pancreatic insulin production. Aside from the role as a blood glucose regulator, insulin also plays a role in anti-inflammatory modulation. Omentoplasty can be used to wrap organ or tissue structures. The Omentum has unique biological functions, including promote tissue regeneration and anti-inflammatory effect. The study evaluates the effect of Sleeve Gastrectomy and pancreas Omentoplasty procedures on β cell insulin expression and Interleukin-1β (IL-1β) serum levels in non-obese diabetes mellitus subjects.Methods: Experimental study with "post-test control group design" on 27 rats with Diabetes Mellitus was divided into 3 groups: K (control), P1 (Sleeve Gastrectomy), P2 (Sleeve Gastrectomy + Omentoplasty). 10 days after procedure, we evaluated the insulin expression of β cells using monoclonal antibody anti-insulin stain and IL-1β serum levels using rat IL-1β Enzyme-Linked Immunosorbent Assay (ELISA) kit. Statistical analysis with Kruskal Wallis and Mann Whitney test. Correlation test with Spearman.Results: β cell insulin expression increased in P2 (p=0.020), compared to control. While the IL-1β serum levels reduced significantly in all groups (p<0.001) compared to control. Moderate negative correlation (r = -0.476) between β cell insulin expression and IL-1β serum levels.Conclusion: Sleeve gastrectomy and omentoplasty increased β cell insulin expression and decreased IL-1 β serum levels in non-obese rats with diabetes mellitus.
