Objectives: There is renewed interest in targeting the glucose-dependent insulinotropic polypeptide receptor (GIPR) for treatment of obesity and type 2 diabetes. G-protein coupled receptor desensitisation is suggested to reduce the long-term efficacy of glucagon-like-peptide 1 receptor (GLP-1R) agonists and may similarly affect the efficacy of GIPR agonists. We explored the extent of pancreatic GIPR functional desensitisation with sustained agonist exposure.

Metabolic dysfunction-associated steatohepatitis (MASH), formerly known as nonalcoholic steatohepatitis (MASH), is a major risk factor for cirrhosis and hepatocellular carcinoma (HCC) and a leading cause of liver transplantation. MASH is caused by an accumulation of toxic fat molecules in the hepatocyte which leads to inflammation and fibrosis. Inadequate human "MASH in a dish" models have limited our advances in understanding MASH pathogenesis and in drug discovery.

Background: Kettlebell (KB) swing exercises, whether performed using shoulder height (SHS) or overhead (OHS) swing variations in therapeutic or strength and conditioning settings, are posterior chain dominant exercises that require hip extension contributions when performed correctly.

Purpose/ Hypothesis: The primary purpose of this study was to evaluate the effect of swing style (SHS, OHS) and KB mass on hip extension kinematics and kinetics in young adult females. A secondary purpose was to determine the effects of swing style and KB mass on the forces applied to the total body center of mass and KB.

Aims: Cancer cachexia affects up to 80 % of patients with advanced cancer and accounts for >20 % of all cancer-related deaths. Sarcolemmal localization of dystrophin, a key protein within the dystrophin-glycoprotein complex (DGC), is perturbed in multiple muscle wasting conditions, including cancer cachexia, indicating a potential role for dystrophin in the maintenance of muscle mass. Strategies to preserve dystrophin expression at the sarcolemma might therefore combat muscle wasting.

Introduction: White matter hyperintensity volumes (WMHVs) are disproportionally prevalent in individuals with Alzheimer's disease (AD), potentially reflecting neurovascular injury. We quantify the association between AD polygenic risk score (AD-PRS) and WMHV, exploring single-nucleotide polymorphisms (SNPs) that are proximal to genes overexpressed in cerebrovascular cell species.

Methods: In a UK-Biobank sub-sample (mean age = 64, range = 45-81 years), we associate WMHV with (1) AD-PRS estimated via SNPs across the genome (minus apolipoprotein E [APOE] locus) and (2) AD-PRS estimated with SNPs proximal to specific genes that are overexpressed in cerebrovascular cell species.

Background: Globally, there is a rapidly increasing proportion of women studying and practising healthcare. This has been accompanied by a reducing proportion of males in most healthcare professions. This has been a contributory factor to the decreasing health staffing due to the tendency of females to work fewer hours and leave their profession earlier.

Adolescent and young adult cancer survivors (AYAs) experience clinically significant distress and have limited access to supportive care services. Interventions to enhance psychological well-being have improved positive affect and reduced depression in clinical and healthy populations and have not been routinely tested in AYA survivors. We are optimizing a web-based positive skills intervention for AYA cancer survivors called Enhancing Management of Psychological Outcomes With Emotion Regulation (EMPOWER) by: (1) determining which intervention components have the strongest effects on well-being and (2) identifying demographic and individual difference variables that mediate and moderate EMPOWER's efficacy.

The intestinal immune system must concomitantly tolerate food and commensals and protect against pathogens. Antigen-presenting cells (APCs) orchestrate these immune responses by presenting luminal antigens to CD4 T cells and inducing their differentiation into regulatory (pTreg) or inflammatory (Th) subsets. We used a proximity labeling method (LIPSTIC) to identify APCs that presented dietary antigens under tolerizing and inflammatory conditions and understand cellular mechanisms by which tolerance to food is induced and can be disrupted by infection.

(partridgeberry; family Rubiaceae) is a creeping, understory plant native to eastern North America. The twinned, tubular flowers of this distylous plant are bright white and produce volatile organic compounds (VOCs). Partridgeberry has intermorph incompatibility and thus requires pollinators to move pollen from one morph to the other.

Introduction: Opioid use disorder (OUD) is a serious and persistent problem in the United States with limited non-pharmacological treatment options, especially for the concomitant sleep disorders experienced by most individuals with addiction. While new, non-invasive interventions such as low-intensity focused ultrasound (LIFU) have shown promise in targeting the brain regions impacted throughout addiction and recovery, the devices used are not amenable to outpatient treatment in their current form factor and cannot be used at night during sleep. To bridge this gap and provide a much-needed treatment option for repeated, at-home use, we developed a wearable LIFU device out-of-clinic use.

Prenylation consists of the modification of proteins with either farnesyl diphosphate (FPP) or geranylgeranyl diphosphate (GGPP) at a cysteine near the C-terminus of target proteins to generate thioether-linked lipidated proteins. In recent work, metabolic labeling with alkyne-containing isoprenoid analogues including C15AlkOPP has been used to identify prenylated proteins and track their levels in different diseases. Here, a systematic study of the impact of isoprenoid length on proteins labeled with these probes was performed.

Article Synopsis
  • The opioid crisis has evolved into a global issue affecting various socioeconomic and cultural areas, with traditional treatment methods proving insufficient.
  • A narrative review was conducted using multiple databases to explore the complex factors contributing to this epidemic, acknowledging the potential for bias in article selection.
  • Despite some progress with Opioid Substitution Therapy, U.S. overdose deaths remain alarmingly high and are projected to increase; the authors suggest a need for a new treatment approach that targets brain neurotransmitter systems for better management.

Article Synopsis
  • Borderline personality disorder (BPD) and post-traumatic stress disorder (PTSD) share similar neurobiological features, suggesting that BPD might be better classified as "traumatic personality stress disorder" (TPSD).
  • The study explores how psychedelic-assisted therapy (PAT) could effectively treat both BPD and PTSD, emphasizing its role in stabilizing reward functions.
  • Reclassifying BPD as TPSD may lead to more personalized treatment approaches, reduce stigma, and improve understanding and management of related psychological conditions.

Background: Asthma in children is a leading cause of missed school days, emergency department visits, and hospitalizations. Approximately 40% of children with asthma experience uncontrolled disease and annual exacerbations. There is a need for a validated composite tool for children, such as the Asthma Impairment and Risk Questionnaire (AIRQ), which was developed to assess current control and predict exacerbations in adolescents and adults with asthma.

We present multiple derivations of the Total Radiation Belt Electron Content (TRBEC), an indicator of the global number of electrons that instantaneously occupy the radiation belts. Derived from electron flux measurements, the TRBEC reduces the spatial information into a scalar quantity that concisely describes global aspects of the system. This index provides a simple, global, and long-term assessment of the radiation belts that enables systematic analysis.

Asthma has been increasingly recognized as a heterogeneous disease; however, many patients with asthma have allergic asthma (AA). Inhaled corticosteroids and other inhalers have been integral in treating many symptoms of asthma, but these medications do not completely address the disease's underlying mechanism. Pediatric asthma imposes a substantial burden on patients and the health care system.
