We report a case of 59-year-old female with non-alcoholic-steato-hepatitis (NASH) induced cirrhosis, who presented with hematochezia. The patient had a history of bleeding esophageal varices treated with endoscopic variceal ligation (EVL). Colonoscopy showed large rectal varices which were the source of her lower gastrointestinal bleeding (LGIB). Since endoscopic treatment for LGIB are limited, and because the patient had portal vein thrombosis which contraindicated transjugular intrahepatic portosystemic shunt (TIPS), we performed percutaneous transhepatic embolization of her rectal varices using a new mixture of embolic and sclerotic agents, followed by Amplatzer plug 2 (AVP 2)...

A central challenge in pharmaceutical research is to investigate genetic variation in response to drugs. The Collaborative Cross (CC) mouse reference population is a promising model for pharmacogenomic studies because of its large amount of genetic variation, genetic reproducibility, and dense recombination sites. While the CC lines are phenotypically diverse, their genetic diversity in drug disposition processes, such as detoxification reactions, is still largely uncharacterized. Here we systematically measured RNA-sequencing expression profiles from livers of 29 CC lines under baseline conditions...

INTRODUCTION: Serum vitamin D concentration is a major contributing factor for increasing the risk of fall and fall-related injuries in older adults. However, when prescribed and supplemented for these populations, the outcomes are controversial, and in several cases no improvement has been reported in reducing the risk of recurrent falls. This study aimed to examine the association between serum vitamin D concentration and recurrent falls in Iranian older adults. METHODS: This cohort study was conducted in the emergency departments of two university hospitals...

Novel strategies to combat the ever increasing burden of drug resistance in Mycobacterium tuberculosis (MTB) causing tuberculosis (TB) remains a global concern. The ability of MTB to sense and adapt to restricted iron conditions in the hostile environment is essential for their survival and confers the basis of their success as dreadful pathogen. The striking and clinically relevant virulence trait of MTB is its ability to form biofilms and adhere to the host cells. The present study elucidated the effect of iron deprivation on biofilm formation and cell adherence of Mycobacterium smegmatis, a non-pathogenic surrogate of MTB...

During the course of metabolic profiling of lead Compound 1, glutathione (GSH) conjugates were detected in rat bile, suggesting the formation of reactive intermediate precursor(s). This was confirmed by the identification of GSH and N-acetylcysteine (NAC) conjugates in microsomal incubations. It was proposed that bioactivation of Compound 1 occurs via the formation of a di-iminoquinone reactive intermediate through the involvement of the C-2 and C-5 nitrogens of the pyrimidine core. To further investigate this hypothesis, structural analogues with modifications at the C-5 nitrogen were studied for metabolic activation in human liver microsomes supplemented with GSH/NAC...

BACKGROUND: The two main options for renal allograft preservation are static cold storage (CS) and machine perfusion (MP). There has been considerably increased interest in MP preservation of kidneys, however conflicting evidence regarding its efficacy and associated costs have impacted its scale of clinical uptake. Additionally, there is no clear consensus regarding oxygenation, and hypo- or normothermia, in conjunction with MP, and its mechanisms of action are also debated. The primary aims of this article were to elucidate the benefits of MP preservation with and without oxygenation, and/or under normothermic conditions, when compared with CS prior to deceased donor kidney transplantation...

Producing meiosis-competent germ cells (GCs) from embryonic stem cells (ESCs) is essential for developing advanced therapies for infertility. Here, a novel approach is presented for generation of GCs from ESCs. In this regard, microparticles (MPs) have been developed from alginate sulfate loaded with bone morphogenetic protein 4 (BMP4). The results here show that BMP4 release from alginate sulfate MPs is significantly retarded by the sulfated groups compared to neat alginate. Then, BMP4-laden MPs are incorporated within the aggregates during differentiation of GCs from ESCs...

Modern microsurgery is a long and complex task requiring the surgeon to handle multiple microscope controls while performing the surgery. Eye tracking provides an additional means of interaction for the surgeon that could be used to alleviate this situation, diminishing surgeon fatigue and surgery time, thus decreasing risks of infection and human error. In this paper, we introduce a novel algorithm for pupil detection tailored for eye images acquired through an unmodified microscope ocular. The proposed approach, the Hough transform, and six state-of-the-art pupil detection algorithms were evaluated on over 4000 hand-labeled images acquired from a digital operating microscope with a non-intrusive monitoring system for the surgeon eyes integrated...

In Iran, as in most countries, cardiovascular diseases are the leading cause of death (highest mortality rate), but rank third in terms of disease burden. On the other hand, the relationship between high salt intake, hypertension, and cardiovascular disease has been proven. Food consumption pattern in Iran shows that consumption of salt, pickled foods and salty snacks is common. Regarding the World Health Organization (WHO) target for salt intake (about 5 g per day), the evidence indicates that Iranian people consume 2-3 times more than the recommended amount of salt...
