The effect of Myo-Inositol supplement on molecular regulation of folliculogenesis, steroidogenesis, and assisted reproductive technique outcomes in patients with polycystic ovarian syndrome.

Research Question: The mechanism of Myo-Inositol, as an adjuvant, on key signaling pathways related to oocyte maturation, fertilization rate, and embryo quality as well as ovarian steroidogenesis in cumulus cells of PCOS patients, is still unclear.

Design: Infertile patients who were candidates for ART cycles were divided into three groups (n = 30 in each group), including group 1: PCOS patients only receiving folic acid, group 2: PCOS patients receiving daily Myo-Inositol combined with folic acid, and a control group (group 3): normal ovulatory women without PCOS receiving only folic acid from 1 month prior to IVF cycle until the day of ovum pick up. During the ART procedure, oocytes maturation, fertilization rate, and embryo quality were assessed.

Accuracy of Machine Learning Models to Predict Mortality in COVID-19 Infection Using the Clinical and Laboratory Data at the Time of Admission.

Aim This study aimed to develop a predictive model to predict patients' mortality with coronavirus disease 2019 (COVID-19) from the basic medical data on the first day of admission.

The outcome of patients was also recorded as discharge or death.

The Role of Machine Learning and Radiomics for Treatment Response Prediction in Idiopathic Normal Pressure Hydrocephalus.

Introduction Ventricular shunting remains the standard of care for patients with idiopathic normal pressure hydrocephalus (iNPH); however, not all patients benefit from the shunting. Prediction of response in advance can result in improved patient selection for ventricular shunting. This study aims to develop a machine learning predictive model for treatment response after shunt placement using the clinical and radiomics features.

Zinc Supplementation Might Not Affect Serum Leptin and Adiponectin Levels in Adults: A Systematic Review and Meta-Analysis of Randomized Controlled Clinical Trials.

Background: Zinc as one of the important trace elements in human health has been suggested to be a supplement for modifying the level of adipokines, whereas findings from studies have been inconsistent. This study aimed to systematically review the evidence provided by randomized controlled trials (RCTs) regarding the effect of zinc supplementation on serum adipokines levels.

Methods: PubMed, Google Scholar, Web of Science, and Scopus were systematically searched up to June 2019.

The aim of the present randomized controlled trial was to evaluate the effect of a micronized resveratrol supplement on glycemic status, lipid profile, and body composition in patients with type 2 diabetes mellitus (T2DM). A total of 71 overweight patients with T2DM (body mass index ranged 25-30) were randomly assigned to receive 1000 mg/day trans-resveratrol or placebo (methyl cellulose) for 8 weeks. Anthropometric indices and biochemical indices including lipid and glycemic profile were measured before and after the intervention.

The effect of resveratrol supplementation on the expression levels of factors associated with cellular senescence and sCD163/sTWEAK ratio in patients with type 2 diabetes mellitus: study protocol for a double-blind controlled randomised clinical trial.

Introduction: Over the past decades, the number of people with type 2 diabetes (T2D) has increased globally. One of the major complications in these patients is cardiovascular disease; it seems that the cell proliferation inhibition can improve vascular function in these patients. It is proposed that peroxisome proliferator-activated receptor alpha (PPARα) can induce cell cycle arrest via cyclin-dependent kinase inhibitor 2A (p16) activation.

The myo-inositol effect on the oocyte quality and fertilization rate among women with polycystic ovary syndrome undergoing assisted reproductive technology cycles: a randomized clinical trial.

Estimating blood transfusion requirements in preparation for a major earthquake: the Tehran, Iran study.

Introduction: Tehran, Iran, with a population of approximately seven million people, is at a very high risk for a devastating earthquake. This study aims to estimate the number of units of blood required at the time of such an earthquake.

Methods: To assume the damage of an earthquake in Tehran, the researchers applied the Centre for Earthquake and Environmental Studies of Tehran/Japan International Cooperation Agency (CEST/JICA) fault-activation scenarios, and accordingly estimated the injury-to-death ratio (IDR), hospital admission rate (HAR), and blood transfusion rate (BTR).

Cryoablation for surgical treatment of chronic atrial fibrillation combined with mitral valve surgery: a clinical observation.

Objective: Although the classical Cox-Maze III is the gold standard surgical therapy with a proven efficacy in the treatment of atrial fibrillation (AF), complexity of this procedure has resulted in a search for a simpler, less invasive and more cost-effective method. In this study we evaluated the results of cryosurgical ablation in the treatment of chronic AF in patients undergoing concomitant mitral valve surgery.

Methods: Ninety patients (mean age: 50.

Eighty layer hens were assigned in a completely randomized design to four dietary treatments containing zinc sulphate or organic zinc as Albino-Zn in two levels of 25 or 50 ppm. Feed intake was expressed on a per hen basis. Daily egg collection was expressed on a hen-day basis.

Classic Konno-Rastan procedure: indications and results in the current era.

Diffuse or unresectable subaortic stenosis is difficult to treat and needs aggressive resection to effectively relieve the obstruction. Anterior aortoventriculoplasty, known as the Konno-Rastan procedure, has been shown to effectively tackle the problems encountered in diffuse subaortic stenosis. A retrospective study was carried out on patients who had undergone a Konno-Rastan procedure at our institution from March 1997 to November 2003.

An in vitro comparison between two methods of electrical resistance measurement for occlusal caries detection.

Because of different measurement techniques and the easier design of the CRM prototype, this in vitro study aimed to compare the diagnostic performance and reproducibility of two electrical methods (Electronic Caries Monitor III, ECM and Cariometer 800, CRM) for occlusal caries detection, and to evaluate the effect of staining/discoloration of fissures on diagnostic performance. Hundred and seventeen third molars with no apparent occlusal cavitation were selected. Six examiners inspected all specimens independently, using the CRM, and a subgroup of 4 using the ECM.
