Human hepatic bile acid transporter Na+/taurocholate cotransporting polypeptide (NTCP) represents the liver-specific entry receptor for the hepatitis B and D viruses (HBV/HDV). Chronic hepatitis B and D affect several million people worldwide, but treatment options are limited. Recently, HBV/HDV entry inhibitors targeting NTCP have emerged as promising novel drug candidates. Nevertheless, the exact molecular mechanism that NTCP uses to mediate virus binding and entry into hepatocytes is still not completely understood. It is already known that human NTCP mRNA expression is downregulated under cholestasis. read more Furthermore, incubation of rat hepatocytes with the secondary bile acid taurolithocholic acid (TLC) triggers internalization of the rat Ntcp protein from the plasma membrane. In the present study, the long-term inhibitory effect of TLC on transport function, HBV/HDV receptor function, and membrane expression of human NTCP were analyzed in HepG2 and human embryonic kidney (HEK293) cells stably overexpressing nhibition of NTCP's transporter and receptor function via an intracellularly accessible domain, without substantially affecting its membrane expression. This domain is a promising novel NTCP target site for pharmacological long-acting HBV/HDV entry inhibitors.Gastrointestinal disease burden continues to rise in the United States and worldwide. The development of bioengineering strategies to model gut injury or disease and to reestablish functional gut tissue could expand therapeutic options and improve clinical outcomes. Current approaches leverage a rapidly evolving gut bioengineering toolkit aimed at 1) de novo generation of gutlike tissues at multiple scales for microtissue models or implantable grafts and 2) regeneration of functional gut in vivo. Although significant progress has been made in intestinal organoid cultures and engineered tissues, development of predictive in vitro models and effective regenerative therapies remains challenging. In this review, we survey emerging bioengineering tools and recent methodological advances to identify current challenges and future opportunities in gut bioengineering for disease modeling and regenerative medicine.
We investigated the comparative efficacy and tolerability of augmentation strategies for bipolar depression.
We conducted a systematic review and network meta-analysis of 8 electronic databases for double-blind, randomized controlled trials of adjunctive pharmacotherapies for acute bipolar depression.
We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and applied the Cochrane risk of bias tool for study quality appraisal. Two reviewers independently abstracted data. We resolved all discrepancies by consensus.
Primary outcomes were response and completion of treatment. We estimated summary rate ratios (RRs) and standardized mean differences (SMDs) relative to placebo controls using frequentist random-effects network meta-analysis.
We identified 69 trials meeting eligibility criteria (8,007 participants, 42.8 years, 58.0% female). Adjunctive racemic intravenous ketamine, coenzyme Q10, pramipexole, fluoxetine, and lamotrigine were more effective than placebo. d for additional research exploring novel treatment strategies for bipolar depression, particularly head-to-head studies.Ganglion cysts are the most common soft tissue tumor of the hand and wrist, affecting pediatric and adult populations. Despite their frequency, there is no consensus within the literature regarding the best management of pediatric wrist ganglia, and there are few recent publications examining this topic. We provide an up-to-date literature review examining the current issues and controversies in the management of pediatric wrist ganglia.Mining activities causes heavy metal pollution and adversely affect the ecological safety and human well-being. Phytoremediation-biochar synergy can effectively remediate mine spoils contaminated with heavy metals (HM). A review which focuses exclusively on the application of biochar assisted phytoremediation in HM contaminated mine spoil is lacking. Mechanisms of metal immobilization by biochar, potential plants and contaminated biomass disposal methods has also been reviewed. Availability of biochar feedstock and production conditions, optimization of application rate, application techniques, selection of suitable hyperaccumulators and cost optimization of bulk biochar production are the key to a successful biochar-based HM remediation of mine tailings and coalmine spoil. Presently, herbs and shrubs are mostly used as phytoremediators, use of woody trees would encourage a long-term metal sequestration which would reduce the cost of biomass disposal. Also, use of non-edible plants would prevent the plants from entering the food chain. For a holistic biochar-phytoremediation technique, incineration and pyrolysis can effectively dispose contaminated biomass. From the economical viewpoint, the environment cost-benefit analysis should be considered before considering the feasibility of a technology. Highlights Mass scale in-situ biochar production and economics are keys issues. Biochar assisted phytoremediation for HM contaminated mine spoils. Long term studies using woody biomass needs attention. Disposal of contaminated biomass by pyrolysis method.
The first aim was to study the relationship between Social Cognition (SC) and nonsocial Cognition (n-SC) measures in a group of patients with moderate or severe traumatic brain injury (TBI) to assess the dependence or independence of both types of cognition. The second aim was to explore the relationships between SC measures and generate a model based on the results of these relationships.
Forty-three subacute patients with TBI were included in the study. They were administered a SC battery and n-SC battery. SC battery included the following measures
(IAPS);
(FEEST);
(MSP);
- (RMET); (SDMT). n-SC battery included ; ; ; ;
FEEST, MSP and RMET were related to n-SC measures. The exploratory factor analysis shows a two-factor SC structure Factor 1
(FEEST, MSP and RMET) and Factor 2
(IAPS and SDMT).
The performance of subjects with moderate-to-severe TBI in the SC measures is related, at least partially, by the performance in the n-SC measures. Our SC model shows a two-factor structure characterized by a first factor that brings together SC measures that are highly related to n-SC domains and a second factor that brings together measures whose performance is not influenced by n-SC domains.read more
