Sofosbuvir-based regimen is safe and effective for hepatitis C infected patients with stage 4–5 chronic kidney disease: a systematic review and meta-analysis

Whether sofosbuvir is suitable for hepatitis C virus (HCV) infected patients with severe renal impairment is inconclusive. This systematic review aims to evaluate the safety and effectiveness of SOF-based regimen in the setting of stage 4 and 5 chronic kidney disease (CKD). We conducted a systematic literature search in PubMed, Web of Science, EMBASE and Google Scholar with...

Long noncoding RNA LINC00707 sponges miR-370-3p to promote osteogenesis of human bone marrow-derived mesenchymal stem cells through upregulating WNT2B

BackgroundHuman bone marrow-derived mesenchymal stem cells (HBMSCs) are characterized by multiple differentiation potential and potent self-renewal ability, yet much remains to be elucidated on what determines these properties. Long-chain noncoding RNAs (lncRNAs) have been suggested to be involved in multiple biological processes under physiological and pathological conditions...

The Progress of Anti-HBV Constituents from Medicinal Plants in China

Hepatitis B virus (HBV) infection causing acute and chronic hepatitis is a serious problem worldwide, whereas the current treatment methods are unsatisfactory. Traditional Chinese herbs that have long been used for medicinal purposes are fascinating sources for novel anti-HBV candidates. This paper summarizes the progress of anti-HBV constituents from diverse medicinal plants in...

Primary chondroma of posterior mediastinum with Horner’s syndrome: a case report

Chondroma is a slowly growing, benign cartilaginous tumor which predominantly occurs in long bones of the hands and feet. Primary mediastinal chondroma is rare, especially with Horner’s syndrome. We reported the case of a 31-year-old woman with a posterior mediastinum mass associated with Horner’s syndrome. After complete dissection of the mass, a pathological diagnosis of the...

Programmable time-domain digital-coding metasurface for non-linear harmonic manipulation and new wireless communication systems

Optical non-linear phenomena are typically observed in natural materials interacting with light at high intensities, and they benefit a diverse range of applications from communication to sensing. However, controlling harmonic conversion with high efficiency and flexibility remains a major issue in modern optical and radio-frequency systems. Here, we introduce a dynamic time...

Comparative Studies on the pH Dependence of DOW of Microcystin-RR and -LR Using LC-MS

Microcystins (MCs) are well known worldwide as hepatotoxins produced by cyanobacteria, but little is known about the physicochemical properties of these compounds. The dependence of the n-octanol/water distribution ratio (DOW) of MC-RR and -LR to pH was measured by high-performance liquid chromatography combined with mass spectrometry (LC-MS). There was a remarkable difference in...

Cost Effectiveness of Bosentan for Pulmonary Arterial Hypertension: A Systematic Review

Objectives. Although many studies have reported on the cost-effectiveness of bosentan for treating pulmonary arterial hypertension (PAH), a systematic review of economic evaluations of bosentan is currently lacking. Objective evaluation of current pharmacoeconomic evidence can assist decision makers in determining the appropriate place in therapy of a new medication. Methods...

An Incentive Dynamic Programming Method for the Optimization of Scholarship Assignment

Scholarship assignment is an operations management problem confronting university administrators, which is traditionally solved based on administrators’ personal experiences. This paper proposes an incentive method inspired by dynamic programming to replace the traditional decision-making process in the scholarship assignment. The objective is to find the optimal scholarship...

Investigation of the effect of forming parameters in incremental sheet forming using a micromechanics based damage model

The incremental sheet forming (ISF) process is considered as a feasible solution for forming a variety of small batch and even customised sheet components. The quality of an ISF product is affected by various process parameters, e.g. sheet material, step-down, feed rate, tool diameter and lubricant. To produce an ISF part of sufficient quality and accuracy without defects...

Tissue Distribution and Depuration of the Extracted Hepatotoxic Cyanotoxin Microcystins in Crucian Carp (Carassius carassius) Intraperitoneally Injected at a Sublethal Dose

An acute toxicity experiment was conducted by intraperitoneal injection with a sublethal dose of extracted microcystins (MCs), 50 μg MC-LR (where L = leucine and R = arginine) equivalent/kg body weight (BW), to examine tissue distribution and depuration of MCs in crucian carp (Carassius carassius). Liver to body weight ratio increased at 3, 12, 24, and 48 h postinjection compared...
