BAFF Blockade Attenuates B Cell MALT Formation in Conditional Nlrc5-Deficient Mice With Helicobacter felis Infection.

Helicobacter infection is a key cause of gastric B cell mucosa-associated lymphoid tissue (MALT) lymphoma. This study examined the role of B cell-activating factor (BAFF), a major driver of B cell proliferation and many B cell disorders, in this malignancy using a model in which conditional knockout mice for NOD-like receptor family CARD domain-containing 5 (Nlrc5) are infected with Helicobacter felis. Gastric BAFF production was significantly increased in H.

Implementation of a Telehealth Smoking Cessation Program in Primarily Socioeconomically Disadvantaged Black Patients: Courage to Quit Rolling-Virtual (CTQ-RV).

Background: Preliminary data indicate that smoking cessation offered in a rolling group format is feasible and effective.

Purpose: The current study evaluated the implementation and outcomes of the remote Courage to Quit-Rolling Virtual (CTQ-RV) smoking group treatment compared to its precursor in-person format (Courage to Quit-Rolling, CTQ-R).

Methods: Virtual materials for CTQ-RV were adapted from in-person evidence-based programming, thus content in both groups was similar but delivered via videoconference or in-person.

Assessing real-time positive subjective effects of alcohol using high-resolution ecological momentary assessment in risky versus light drinkers.

Background: High-resolution ecological momentary assessment (HR-EMA) can assess acute alcohol responses during naturalistic heavy drinking episodes. The goal of this study was to use HR-EMA to examine drinking behavior and subjective responses to alcohol in risky drinkers (moderate-severe alcohol use disorder [MS-AUD], heavy social drinkers [HD]) and light drinkers (LD). We expected that risky drinkers would endorse greater alcohol stimulation and reward, with lower sedation, than LD, even when controlling for amount of alcohol consumed.

Courage to Quit® rolling group: Implementation in an urban medical center in primarily low-income Black smokers.

Background: Continuous "rolling" tobacco group treatments may help reduce cessation disparities by increasing access among underserved people who smoke cigarettes. We evaluated the implementation of a rolling enrollment adaptation of an evidence-based tobacco treatment group intervention, Courage to Quit®-Rolling (CTQ®-R).

Methods: The 4-session CTQ®-R incorporating psychoeducation, motivational enhancement, and cognitive behavioral skills was evaluated by examining feasibility and preliminary program outcomes with a pre-post design using the SQUIRE method in a sample of 289 primarily low-income, Black people who smoke.

Hearing loss increases with size but not site of tympanic membrane perforation in Aboriginal Australian children in remote locations.

Objective: To investigate the effect of size, site, and activity of tympanic membrane (TM) perforation on hearing loss (HL) in Aboriginal and Torres Strait Islander (ATSI) children.

Design: Observational study.

Methodology: Children aged 5-18 years who identified as ATSI at seven Anangu community schools within the Anangu Pitjantjatjara Yankunytjatjara Lands and Maralinga Lands of South Australia underwent 4-frequency pure-tone audiometry (0.

Cue Reactivity Effects of Heated Tobacco Product Use in Current, Former, and Never Smokers in the United States.

Introduction: Heated tobacco products (HTPs) share similar characteristics as combustible cigarettes and electronic nicotine delivery systems (ENDS) and thus may serve as cues for smoking and vaping. While HTP familiarity is low in the United States, HTPs may be perceived as a less harmful alternative to cigarettes.

Aims And Methods: The present study examined if visual exposure to HTP use influenced cigarette and e-cigarette craving in a large national sample of adults with varied smoking patterns.

The effect of acute alcohol intoxication on alcohol cue salience: An event-related brain potential study.

Objective: Alcohol cue salience is considered core to the broader understanding of drinking behaviors. In the present research, we sought to build the knowledge of alcohol cue salience by exploring P3 responses to alcohol images among social drinkers within a large-scale alcohol-administration study.

Method: Participants ( = 246) were randomly assigned to receive either a moderate dose of alcohol (target BAC = .

Parent's anxiety links household stress and young children's behavioral dysregulation.

Young children rely heavily on their caregivers to gain information about the environment, especially during times of duress. Therefore, considering parental assessments of behavior in the context of stressful environments may better facilitate our understanding of the longstanding association between early environmental stressors and changes in child behavior and physiology. Confirming many previous reports, a higher degree of household stress exposure was associated with elevated mental health symptoms in 2- to 6-year-old children (N = 115; anxiety and externalizing behaviors), which were verified in a subset of children with laboratory-based behaviors (N = 46).

Optimizing the Interaction of Exercise Volume and Metformin to Induce a Clinically Significant Reduction in Metabolic Syndrome Severity: A Randomised Trial.

Insulin resistance is a central mediating factor of the metabolic syndrome (MetS), with exercise training and metformin proven antidotes to insulin resistance. However, when the two therapies are combined there is conflicting data regarding whether metformin blunts or improves exercise training-induced adaptations. The volume of exercise (duration, intensity, and frequency) on the interaction of exercise training and metformin has yet to be investigated.

Free-Wilson Analysis of Comprehensive Data on Phosphoinositide-3-kinase (PI3K) Inhibitors Reveals Importance of -Methylation for PI3Kδ Activity.

Phosphoinositide-3-kinase δ (PI3Kδ) is a critical regulator of cell growth and transformation and has been explored as a therapeutic target for a range of diseases. Through the exploration of the thienopyrimidine scaffold, we have identified a ligand-efficient methylation that leads to remarkable selectivity for PI3Kδ over the closely related isoforms. Interrogation through the Free-Wilson analysis highlights the innate selectivity the thienopyrimidine scaffold has for PI3Kδ and provides a predictive model for the activity against the PI3K isoforms.

Systemic hypersensitivity to fosaprepitant - A report of two cases.

Fosaprepitant is a widely administered antiemetic used mainly for moderately to highly emetogenic chemotherapy. Local injection site reactions are the most common type of infusion reaction reported from fosaprepitant. At our institution, two separate patients have experienced systemic hypersensitivity reactions to their infusions of fosaprepitant.

Effectiveness of a lifestyle modification programme in weight maintenance in obese subjects after cessation of treatment with Orlistat.

Objective: To examine the efficacy of a lifestyle modification programme in weight maintenance for obese subjects after cessation of treatment with Orlistat.

Methods: Fifty-five subjects with and without diabetes mellitus were randomized to a lifestyle modification programme or to usual care at the end of 6 months' treatment with Orlistat. The intervention programme was nutritionist led, consisting of components of dietary management, physical activity, peer group support and discussion using techniques of self-monitoring, stimulus control and cognitive restructuring.

Molecular biology of Rh proteins and relevance to molecular medicine.

The Rhesus (Rh) blood group system is expressed by a pair of 12-transmembrane-domain-containing proteins, the RhCcEe and RhD proteins. RhCcEe and RhD associate as a Rh core complex that comprises one RhD/CcEe protein and most likely two Rh-associated glycoproteins (RhAG) as a trimer. All these Rh proteins are homologous and share this homology with two human non-erythroid proteins, RhBG and RhCG.

Ligation of CD47 mediates phosphatidylserine expression on erythrocytes and a concomitant loss of viability in vitro.

CD47 ligation has been shown to induce phosphatidylserine (PS) expression as part of a death pathway in nucleated blood cells. Using Annexin V binding assays we showed that ligation of CD47 with the specific CD47-binding peptide 41NK, anti-CD47 monoclonal antibody, and its natural ligand thrombospondin-1 also induced PS expression on enucleated erythrocytes. PS expression was associated with a concomitant loss of erythrocyte viability in vitro.

Expression of phosphatidylserine (PS) on wild-type and Gerbich variant erythrocytes following glycophorin-C (GPC) ligation.

Glycophorin-C (GPC) is a 40 kDa glycoprotein expressed on erythrocytes and is a receptor for the malarial parasite Plasmodium falciparum to invade these cells. A link between GPC binding (ligation) and phosphatidylserine (PS) expression on erythrocytes has been suggested by its appearance on P. falciparum-infected erythrocytes.

The effect of orlistat-induced weight loss, without concomitant hypocaloric diet, on cardiovascular risk factors and insulin sensitivity in young obese Chinese subjects with or without type 2 diabetes.

Background: We examined the weight-losing effect of orlistat treatment on insulin sensitivity and cardiovascular risk factors in a group of severely obese young Chinese patients with or without type 2 diabetes mellitus.

Methods: Obese patients with diabetes (n = 33) and obese nondiabetic patients (n = 27) were given orlistat, 120 mg 3 times daily, without a concomitant hypocaloric diet for 6 months (body mass index [calculated as weight in kilograms divided by the square of height in meter; kg/m2] range, 27.8-47.
