Effect of Green Tea Ingestion on Postprandial Triglyceride Levels in Young Women

Introduction: High blood triglyceride (TG) level is a risk factor for cardiovascular disease. Green tea, as a beverage, may reduce postprandial blood TG level through inhibition of fat absorption in the intestinal lumen. The aim of this study was to assess the difference of postprandial blood TG level changes between treatment group (high-fat meal and green tea beverage containing 738 mg of catechins) and control group (high-fat meal and plain water containing 0 mg of catechins). Methods: The study was a randomized, single-blind, parallel-group clinical trial including 40 healthy young women. Blood was collected immediately before the meal and then at 2 and 4 h thereafter of each group. Method of TG measurement: GPO-PAP, using Beckman CX 5-CE machine and Good’s buffer reagent. Results: Postprandial blood TG level at 4 h in the treatment group was significantly lower compared to the control group (1.00 ± 0.27 vs. 1.22 ± 0.34 mmol/L, p = 0.03). The change in blood TG level from baseline to 4 h postprandial was also significantly lower in the treatment group compared to the control group (0.21 ± 0.14 vs. 0.37 ± 0.26 mmol/L, p = 0.02). Conclusion: It was concluded that green tea ingestion during high fat meal suppressed postprandial elevation of TG 4 hour after meal

Development and characterization of an automated portable wound irrigation device for diabetic ulcers

Patients with diabetes mellitus may experience peripheral neuropathy and extremity system impairment, which may lead to ulceration if the treatments are delayed. Diabetic ulcers, unfortunately, are chronic, which require proper treatments, including debridement and bacterial removal using an irrigation device. To date, commercial irrigation devices included pulsed-lavage, bulb syringe, and gravity bags. Unfortunately, the devices have limitations in terms of portability, measurability, controllability, and disposability. To tackle the limitations, this study aims to design, fabricate, and characterize an automated portable wound irrigation device (Apdice), which is controllable non-disposable, and portable. The device was designed and fabricated using a lightweight construction, a rechargeable battery, and non-disposable materials to support the portability and non-disposable means. Meanwhile, the proportional-derivative-integral controller with its peripheral components were featured to enable controllability. Furthermore, the device was also tested regarding the contamination using a particle counter, and appeared to be contamination free. In short, Apdice showed a robust technological performance. However, it is also worth the try to test the contamination test against biological agents to guarantee the biocompatibility of the device

Vitamin D supplementation alleviates insulin resistance in prediabetic rats by modifying IRS-1 and PPARγ/NF-κB expressions

BackgroundPrediabetes is a condition of intermediate hyperglycemia that may progress to type 2 diabetes. Vitamin D deficiency has been frequently linked to insulin resistance and diabetes. The study aimed to investigate the role of D supplementation and its possible mechanism of action on insulin resistance in prediabetic rats.MethodThe study was conducted on 24 male Wistar rats that were randomly divided into 6 rats as healthy controls and 18 prediabetic rats. Prediabetic rats were induced with a high-fat and high-glucose diet (HFD-G) combined with a low dose of streptozotocin. Rats with the prediabetic condition were then randomized into three groups of 12-week treatment: one group that received no treatment, one that received vitamin D3 at 100 IU/kg BW, and one group that received vitamin D3 at 1000 IU/kg BW. The high-fat and high-glucose diets were continuously given throughout the twelve weeks of treatment. At the end of the supplementation period, glucose control parameters, inflammatory markers, and the expressions of IRS1, PPARγ, NF-κB, and IRS1 were measured.ResultsVitamin D3 dose-dependently improves glucose control parameters, as shown by the reduction of fasting blood glucose (FBG), oral glucose tolerance test (OGTT), glycated albumin, insulin levels, and markers of insulin resistance (HOMA-IR). Upon histological analysis, vitamin D supplementation resulted in a reduction of the islet of Langerhans degeneration. Vitamin D also enhanced the ratio of IL-6/IL-10, reduced IRS1 phosphorylation at Ser307, increased expression of PPAR gamma, and reduced phosphorylation of NF-KB p65 at Ser536.ConclusionVitamin D supplementation reduces insulin resistance in prediabetic rats. The reduction might be due to the effects of vitamin D on IRS, PPARγ, and NF-κB expression

Practical Guidelines Management of Graves Ophthalmopathy

Graves’ ophthalmopathy is the most common extra-thyroid manifestation in patients with Graves’ disease, based on inflammatory and autoimmune conditions in orbital tissue. This practical guideline was formed by a multidiciplinary team, and is intended to provide guidance for diagnosis and management of Graves’ ophthalmopathy in daily clinical practice to improve quality of care and treatment outcome
