Background: Dipeptidyl peptidase-4 inhibitors provide potent antidiabetic effects in patients with type 2 diabetes mellitus (T2DM), but their role in the presence of nonalcoholic fatty liver disease (NAFLD) is not well-known.

Objective: The aim of this clinical trial was to evaluate the effects of sitagliptin on the metabolic profile and liver test results in metformin-treated patients with T2DM and NAFLD.

Methods: This was a prospective, 12-week, single-center, comparative randomized clinical trial enrolling 66 adult patients with T2DM and NAFLD (diagnosed by ultrasound).

Objective: We hypothesize that synbiotic supplementation could modulate the intestinal microbiota and subsequently, improve the condition of hypothyroid patients.

Methods: Fifty-six adult hypothyroid patients were recruited to this double-blind, placebo-controlled, randomized clinical trial. The intervention was 10 weeks of synbiotic (500 mg of 109 CFU/g probiotics plus fructo-oligosaccharide, n = 28) compared to placebo (lactose, magnesium stearate, talc, and silicon dioxide, n = 28).

With technologies that have democratized the production and reproduction of information, a significant portion of daily interacted posts in social media has been infected by rumors. Despite the extensive research on rumor detection and verification, so far, the problem of calculating the spread power of rumors has not been considered. To address this research gap, the present study seeks a model to calculate the Spread Power of Rumor (SPR) as the function of content-based features in two categories: False Rumor (FR) and True Rumor (TR).

In this work, we focus our attention on the influence of 2nd-row transition metals on the structural geometries, electronic structures, and absorption characteristics of porphyrin linked with the C fullerene with oligo-p-phenyleneethynylenes (MP-C-oligo-PPEs) compounds. The DFT/B3PW91-D3 and CAM-B3LYP-D3/6-31G (d) calculations revealed that various metals embedded within the porphyrin moiety give different bridge conformations and different HOMO-LUMO energy levels. We calculate the UV-Vis spectra and absorption parameters using the time-dependent ZINDO/S approach.

Background: The prevalence of hypothyroidism is increasing worldwide. Emerging evidence suggests that modulating the gut microbiota in patients with hypothyroidism through prebiotic and probiotic supplementation may have beneficial health effects. We hypothesize that selective modulation of the intestinal microbiota by synbiotic supplementation could improve metabolic status, mood, and quality of life in hypothyroid patients.

Article Synopsis
  • Diabetes is a progressive disease that affects organ function and can lead to complications like diabetic nephropathy, which is the main cause of chronic kidney disease.
  • The glycocalyx, a crucial part of blood vessel linings, is damaged during diabetic nephropathy, prompting a study to explore its relationship with the disease.
  • A systematic review of 19 relevant articles revealed that oxidative stress from diabetes impacts kidney endothelial cells, contributing to kidney damage and potential albuminuria.

Purpose: The aim of this study was to assess the correlation of hemoglobin A1c (HbA1c) levels with choroidal thickness in patients with type 2 diabetes mellitus (DM) using spectral domain optical coherence tomography (SD-OCT).

Methods: In this prospective case series, 180 eyes from 90 patients with type 2 DM were classified into three study groups based on HbA1c values: group 1 included patients with good glycemic control (HbA1c 7%), group 2 included patients with moderate glycemic control (HbA1c between 7% and 8%), and group 3 included patients with poor glycemic control (HbA1c 8%). Additionally, 50 eyes from 25 non-diabetic subjects were enrolled to group 4 as a control group.

A simple and fast method named microfunnel-filter-based emulsification microextraction is introduced for an efficient determination of some organophosphorus pesticides including diazinon, malathion, and chlorpyrifos in the environmental samples including the river, sea, and well water. This method is based upon the dispersion of a low-toxicity organic solvent (dihexyl ether), as the extractant, in a high volume of an aqueous sample solution (45 mL). It is implemented without a centrifugation step, and using a syringe filter and a micro-funnel, the phase separation and transfer of the enriched analytes to the gas chromatograph are simply achieved.

Lifestyle modification is the cornerstone of diabetes prevention and treatment. Weight loss through caloric restriction (CR) is effective in improving glycemic control, though it is difficult for patients to follow in practice, and remains critical to achieve optimal glucose homeostasis. In this review, we look at what is known about the molecular pathways involved in CR-induced insulin sensitivity and improved insulin resistance.

A novel liquid-liquid microextraction method, namely, solvent-vapor-assisted liquid-liquid microextraction for the determination of dimethyl phthalate, diethyl phthalate, dibutyl phthalate and bis(2-ethylhexyl) phthalate in the aqueous samples using gas chromatography with mass spectrometry was developed. In the proposed method, extracting solvent was heated, and solvent vapor as the extracting phase was injected into the sample solution. As a result of the low temperature of the sample solution and higher density of the extracting phase than the aqueous medium, solvent vapor was condensed and an organic-phase drop formed in the bottom of sample tube.

Introduction: It is estimated that Iran accounted for about 1% of hip fracture burden of the world in 2007, but these data are based on incomplete evidence. As the country's population is ageing, it is expected that a dramatic rise in hip fracture incidence will result. There is no single national study that accurately estimates the incidence of all hip fractures in the country or identifies the direct costs for affected patients.

Background: Prenatal exposure to air pollutants can increase the risk of adverse birth outcomes and susceptibility to a number of complex disorders later in life. Despite this general understanding, the molecular and cellular responses to air pollution exposure during early life are not completely clear.

Objective: The aims of this study are to test the association between air pollution and adverse pregnancy outcomes, and to determine whether the levels of maternal and cord blood and of placental DNA methylation during pregnancy predict adverse birth outcomes in polluted areas.

Background: Osteoporosis is becoming a health concern worldwide. Considering the fact that prevention plays an important role in reducing the burden of this silent disease and in view of the limited resources available, many countries have adopted certain programs to fight osteoporosis through shifting their attention towards at-risk individuals. The Iranian Multicenter Osteoporosis Study (IMOS) is one of these programs.

Background: The present study is designed to assess the incidence rate of osteoporotic fracture and its risk factors, particularly those used to predict the 10-year risk of osteoporotic fracture in FRAX based on the data gathered through a follow up cohort initiated in 2000.

Methods: The present retrospective cohort was conducted on men and women from 40 to 90 years of age enrolled in the IROSTEOPs study. A phone survey was conducted during 2013 and beginning of 2014 to assess the fractures (traumatic/osteoporotic) occurring at the time of inclusion until the date of the telephone survey, its type and mechanism, and the patient's age at the time of accident.
