#1
Katrin Reichel, Olivier Fisette, Tatjana Braun, Olivier F Lange, Gerhard Hummer, Lars V Schäfer
We critically test and validate the CS-Rosetta methodology for de novo structure prediction of α-helical membrane proteins (MPs) from NMR data, such as chemical shifts and NOE distance restraints. By systematically reducing the number and type of NOE restraints, we focus on determining the regime in which MP structures can be reliably predicted and pinpoint the boundaries of the approach. Five MPs of known structure were used as test systems, phototaxis sensory rhodopsin II (pSRII), a subdomain of pSRII, disul_de binding protein B (DsbB), microsomal prostaglandin E2 synthase-1 (mPGES-1), and translocator protein (TSPO)...

By Ji-Fa Zhang, Lian-Hai Shan, Feng Gao, Shuai Huang, Xian-Li Zhou
Five new diterpenoid alkaloids tianshanitine A-E (1-5), along with ten known compounds (6-15), were isolated from the ethanolic extracts of the whole plant of Delphinium tianshanicum W. T. Wang. Their structures were determined based on extensive spectroscopic analyses, including 1D, 2D NMR, HRESIMS, and the structure of tianshanitine C (3) was confirmed by X-ray diffraction analysis. Tianshanitine A (1) is the first example of natural diterpenoid alkaloid containing a benzoyl group at C-1 position. Tianshanitine B (2) is a rare natural diterpenoid alkaloid including a hydroxyl group at C-16 position...

Background: Acute hepatitis B virus (HBV) infection is still a major cause of acute liver failure (ALF), necessitating a high rate of emergency liver transplantation (LTx). Acute infection is followed by high viral replication rates leading to hepatocyte death and, ultimately, ALF. The objective of treating HBV-induced ALF thus is to eliminate, or significantly suppress, HBV replication and therefore reduce cell death and support regeneration. Objective: In this retrospective study, we want to evaluate the timing, the safety, and the long-term virological outcome of this approach...

The genome and structural organization of a novel insect-specific orthomyxovirus, designated Sinu virus, is described. Sinu virus (SINUV) was isolated in cultures of C6/36 cells from a pool of mosquitoes collected in northwestern Colombia. The virus has six negative-sense ssRNA segments. Genetic analysis of each segment demonstrated the presence of six distinct ORFs encoding the following genes: PB2 (Segment 1), PB1, (Segment 2), PA protein (Segment 3), envelope GP gene (Segment 4), the NP (Segment 5), and M-like gene (Segment 6)...

Bariatric surgeries, including Roux-en-Y gastric bypass (RYGB) are currently the best treatment for obesity and obesity-related comorbidities, such as type 2 diabetes. However, the underlying mechanism of bariatric surgeries is not entirely understood. Further investigations are needed to improve the success rate and achieve sustained health benefits. Given that B cell dysregulation is a critical component of etiology in inflammatory diseases, whereas obesity and type 2 diabetes represent two major inflammatory disorders, we investigated the effect of RYGB on B cell inflammation...

OBJECTIVE: Certain aspects of the anterior cerebral artery (ACA) cortical branches tend to vary, including absent or additional arteries, variation in origin, and changes to diameter and length. Knowledge of these factors can be crucial in aneurysm and arteriovenous malformation surgery. Few studies report on these aspects and a South African study have not been completed. Therefore, the aim of this study is to report absent or additional arteries, the origin, diameter and length of ACA cortical branches in a Western Cape population...

The objective of this experiment was to compare the pork quality of entire male pigs and pigs immunized against GnRF (IC males) at both light (64.8kg) and heavy (106kg) liveweights and two feeding regimes (restricted at 2.5 times maintenance and ad libitum). There was no difference in objective measurements (P>0.05) or eating pork quality (P>0.1) between entire male and IC males. Fail rates were reduced by 9.1% and 12% for pork from IC males for quality grade (P=0.007) and re-purchase intention (P=0.001), respectively, compared to pork from entire males...

This study aimed to examine (a) whether mindfulness skills were associated with higher quality of life through lower body shame for treatment-seeking children/adolescents with overweight and obesity and (b) whether this indirect effect was moderated by children/adolescents' age and gender. The sample included 153 children/adolescents with overweight/obesity followed in individual nutrition consultations. Participants completed self-report measures of mindfulness, body shame, and quality of life. Moderated mediation analyses showed that higher levels of mindfulness were associated with better perceived quality of life through lower body shame, but only among girls...

PURPOSE: Urodynamic studies are crucial to neuropathic bladder management and they often determine surgical intervention. However, current evidence indicates that interpretations show poor agreement across physicians. We sought to determine the interrater reliability of urodynamic interpretation in our practice. We hypothesized that there would be strong correlation among pediatric urologists of similar training in a single academic practice. MATERIALS AND METHODS: We retrospectively identified patients with neuropathic bladder who underwent urodynamics at our institution between 2014 and 2015...

OBJECTIVE: Compared with older adults, emerging adults (18-29 years old) entering treatment typically have less severe alcohol use consequences. Also, their unique clinical presentations (e.g., modest initial abstinence motivation) and developmental contexts (e.g., drinking-rich social networks) may make a straightforward implementation of treatments developed for adults less effective. Yet, this has seldom been examined empirically. This study was a secondary analysis of Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity) data examining (a) overall differences between emerging adults and older adults (≥30 years old) on outcomes during treatment and at 1-year follow-up, and (b) whether emerging adults had poorer outcomes on any of the three Project MATCH treatments in particular...

OBJECTIVE: Given the popular association between April 20 ("4/20") and marijuana, the present study examined marijuana use and consequences on 4/20 compared with other days in order to test whether 4/20 is a high-risk, event-specific marijuana use holiday among college student marijuana users. METHOD: Fifty-nine college student marijuana users from three different, large U.S. universities located in Virginia, New Mexico, and Colorado completed daily brief surveys (<10 minutes) over a 12-day (April 15-April 26) period assessing prior-day marijuana use (i...

OBJECTIVE: The need to be thin is pervasive in adolescent culture and is associated with increased risk outcomes among adolescent girls. Body image and behavioral misperception (BIBM) exists when there is a disconnect between body weight perception and actions taken related to perceived weight status. To understand this further, we examined the relationship between BIBM and alcohol use among high school girls in the United States. METHOD: Using 2013 Youth Risk Behavior Survey data, we ran survey-weighted multivariable logistic regression analyses to examine BIBM and (a) lifetime alcohol use, (b) current alcohol use, and (c) current heavy episodic drinking (≥5 drinks in a few hours) among female high school students (N = 6,579)...

OBJECTIVE: There is a paucity of research on the prevalence and consequences of secondhand harms from alcohol. The current study (a) investigated whether secondhand harms can be clustered into latent factors that reflect distinct but related types of harms and (b) examined the associations between experiencing secondhand harms and mental health outcomes, including anxiety, depression, and subjective mental well-being, among first-year Canadian postsecondary students. The moderating effect of living arrangement (i...

Globally, addiction to "ICE" (crystal methamphetamine) is increasing and presents emergency health care services personnel with a number of challenges. This paper reports the first of two major themes arising from a qualitative study investigating health professionals' experiences' managing people presenting to the Emergency Department (ED) after taking "ICE." The theme "Caring for people who use 'ICE' when presenting to EDs" comprises five subthemes. These are: (a) expecting the unexpected: "they're just off their heads"; (b) complexity of care: "underlying trauma and emotional dysregulation";...
