Impact of metabolism-disrupting chemicals and folic acid supplementation on liver injury and steatosis in mother-child pairs.

Background And Aims: Scarce knowledge about the impact of metabolism-disrupting chemicals (MDCs) on steatotic liver disease limits opportunities for intervention. We evaluated pregnancy MDC-mixture associations with liver outcomes, and effect modification by folic acid (FA) supplementation in mother-child pairs.

Methods: We studied ∼200 mother-child pairs from the Mexican PROGRESS cohort, with measured 43 MDCs during pregnancy (estimated air pollutants, blood/urine metals or metalloids, urine high- and low-molecular-weight phthalate [HMWPs, LMWPs] and organophosphate-pesticide [OP] metabolites), and serum liver enzymes (ALT, AST) at ∼9 years post-parturition.

Learning from the first: a qualitative study of the psychosocial benefits and treatment burdens of long-acting cabotegravir/rilpivirine among early adopters in three U.S. clinics.

Introduction: Perspectives on long-acting injectable cabotegravir/rilpivirine (CAB/RPV-LA) from HIV health disparity populations are under-represented in current literature yet crucial to optimize delivery.

Methods: Between August 2022 and May 2023, we conducted in-depth interviews with people with HIV (PWH) at four HIV clinics in Atlanta, Chicago and San Francisco. Eligibility criteria were current CAB/RPV-LA use with receipt of ≥3 injections or CAB/RPV-LA discontinuation.

Metabolism-Disrupting Chemical Mixtures during Pregnancy, Folic Acid Supplementation, and Liver Injury in Mother-Child Pairs.

Background And Aims: Scarce knowledge about the impact of metabolism-disrupting chemicals (MDCs) on liver injury limits opportunities for intervention. We evaluated pregnancy MDC-mixture associations with liver injury and effect modification by folic acid (FA) supplementation in mother-child pairs.

GDF11 and aging biology - controversies resolved and pending.

Since the exogenous administration of GDF11, a TGF-ß superfamily member, was reported to have beneficial effects in some models of human disease, there have been many research studies in GDF11 biology. However, many studies have now confirmed that exogenous administration of GDF11 can improve physiology in disease models, including cardiac fibrosis, experimental stroke, and disordered metabolism. GDF11 is similar to GDF8 (also called Myostatin), differing only by 11 amino acids in their mature signaling domains.

Evaluation of Black Soldier Fly as Food for Pink-Spotted Lady Beetle .

The discovery of new and improved factitious and artificial diets is necessary for cost-effective rearing of predatory arthropods. This study evaluated black soldier fly (BSF) as a suitable alternative food source for rearing the predatory coccinellid (). The hypothesis that BSF larval powder was suitable food to support the growth, development, and reproduction of was tested in the laboratory.

Current practice for the chemical immobilisation of non-domestic feline species: An online survey study.

Background: Safe chemical immobilisation of wild felids is essential for both conservational management and clinical purposes. However, little is known about drug protocols and current practice.

Methods: This study was designed as an online survey based on a questionnaire.

Urine-mediated suppression of mucoidy is counteracted by spontaneous Wzc variants altering capsule chain length.

is a hospital-associated pathogen primarily causing urinary tract infections (UTIs), pneumonia, and septicemia. Two challenging lineages include the hypervirulent strains, causing invasive community-acquired infections, and the carbapenem-resistant classical strains, most frequently isolated from UTIs. While hypervirulent strains are often characterized by a hypermucoid phenotype, classical strains usually present with low mucoidy.

Discrepancy between predicted and measured exercise intensity for eliciting the maximal rate of lipid oxidation.

Background And Aims: Ectopic lipid storage is implicated in type 2 diabetes pathogenesis; hence, exercise to deplete stores (i.e., at the intensity that allows for maximal rate of lipid oxidation; MLO) might be optimal for restoring metabolic health.

Prenatal lead exposure is negatively associated with the gut microbiome in childhood.

Background: Metal exposures are associated with gut microbiome (GM) composition and function, and exposures early in development may be particularly important. Considering the role of the GM in association with many adverse health outcomes, understanding the relationship between prenatal metal exposures and the GM is critically important. However, there is sparse knowledge of the association between prenatal metal exposure and GM later in childhood.

Incorporating Public Health Competencies Into Veterinary Medical Education.

This study evaluates the success of secondary public health education in enhancing a professional degree in veterinary medicine. Dual-degree programs promote multidisciplinary skill attainment crucial to succeed in today's One Health-centered veterinary workforce. Participant demographics were collected including academic background, dual-degree enrollment status, and intended course of study.

Functional substitutions of amino acids that differ between GDF11 and GDF8 impact skeletal development and skeletal muscle.

Growth differentiation factor 11 (GDF11) and GDF8 (MSTN) are closely related TGF-β family proteins that interact with nearly identical signaling receptors and antagonists. However, GDF11 appears to activate SMAD2/3 more potently than GDF8 in vitro and in vivo. The ligands possess divergent structural properties, whereby substituting unique GDF11 amino acids into GDF8 enhanced the activity of the resulting chimeric GDF8.

Self-reported periodontitis and C-reactive protein in Parkinson's disease: a cross-sectional study of two American cohorts.

Periodontitis triggers systemic repercussions, such as elevated levels of high-sensitive C-reactive protein (hs-CRP). This has never been studied within Parkinson's Disease (PD). The aim of this study is to compare hs-CRP levels of self-reported periodontitis cases versus cases without periodontitis in PD patients.

High Fructose Intake Contributes to Elevated Diastolic Blood Pressure in Adolescent Girls: Results from The HELENA Study.

Background: The association between high fructose consumption and elevated blood pressure continues to be controversial, especially in adolescence. The aim of this study was to assess the association between fructose consumption and elevated blood pressure in an European adolescent population.

Methods: A total of 1733 adolescents (mean ± SD age: 14.

Measurement of Human Walking Movements by Using a Mobile Health App: Motion Sensor Data Analysis.

Background: This study presents a new approach to measure and analyze the walking balance of humans by collecting motion sensor data in a smartphone.

Objective: We aimed to develop a mobile health (mHealth) app that can measure the walking movements of human individuals and analyze the differences in the walking movements of different individuals based on their health conditions. A smartphone's motion sensors were used to measure the walking movements and analyze the rotation matrix data by calculating the variation of each xyz rotation, which shows the variables in walking-related movement data over time.

Heparin-mediated dimerization of follistatin.

Heparin and heparan sulfate (HS) are highly sulfated polysaccharides covalently bound to cell surface proteins, which directly interact with many extracellular proteins, including the transforming growth factor-β (TGFβ) family ligand antagonist, follistatin 288 (FS288). Follistatin neutralizes the TGFβ ligands, myostatin and activin A, by forming a nearly irreversible non-signaling complex by surrounding the ligand and preventing interaction with TGFβ receptors. The FS288-ligand complex has higher affinity than unbound FS288 for heparin/HS, which accelerates ligand internalization and lysosomal degradation; however, limited information is available for how FS288 interactions with heparin affect ligand binding.

Upper Lip Tie: Anatomy, Effect on Breastfeeding, and Correlation With Ankyloglossia.

Objectives: There is debate among otolaryngologists and other practitioners about whether upper lip tie contributes to difficulty with breastfeeding and whether upper lip tie and ankyloglossia are linked. Our objectives were to evaluate the anatomy of the upper lip (maxillary) frenulum, to determine if the visual anatomy of the upper lip has an effect on breastfeeding, and to determine whether the occurrence of lip tie and tongue tie are correlated.

Methods: A prospective cohort study of 100 healthy newborns was examined between day of life 3-7.

Temperature dependency of predation: Increased killing rates and prey mass consumption by predators with warming.

Temperature dependency of consumer-resource interactions is fundamentally important for understanding and predicting the responses of food webs to climate change. Previous studies have shown temperature-driven shifts in herbivore consumption rates and resource preference, but these effects remain poorly understood for predatory arthropods. Here, we investigate how predator killing rates, prey mass consumption, and macronutrient intake respond to increased temperatures using a laboratory and a field reciprocal transplant experiment.

The role of polygenic susceptibility to obesity among carriers of pathogenic mutations in MC4R in the UK Biobank population.

Background: Melanocortin 4 receptor (MC4R) deficiency, caused by mutations in MC4R, is the most common cause of monogenic forms of obesity. However, these mutations have often been identified in small-scale, case-focused studies. Here, we assess the penetrance of previously reported MC4R mutations at a population level.

Age-Friendly Communities and Cultural Pluralism: Examining Saskatoon's Chinese-Canadian Social Enclave.

This article uses findings from qualitative interviews to examine the experiences of members of Saskatoon's Chinese-Canadian older-adult community in terms of their realities of aging and access to important geriatric resources. Promoting an understanding of both group experience and a broader conceptualization of age-friendly development, we argue that the notion and implications of a spatial ethnic enclave are replaced in the Saskatoon context by a social enclave. This network of social support is evident in Chinese-Canadian older adults' access to housing, recreation, transportation, and health services.

How Accumulated Wealth Affects Driving Reduction and Cessation.

Background And Objectives: Older adults can expect to live between 6 and 10 years after they give up driving, but driving reduction and cessation (DRC) are not equally experienced by all groups. Individual characteristics such as poor health, impaired vision, older age, and female gender are known to affect DRC. Using cumulative disadvantage theory as a guide, this study assessed the role played by wealth in DRC among older adults.

CRISPR/CAS9-mediated knockout of Abi1 inhibits p185-induced leukemogenesis and signal transduction to ERK and PI3K/Akt pathways.

Background: Abl interactor 1 (Abi1) is a downstream target of Abl tyrosine kinases and a component of the WAVE regulatory complex (WRC) that plays an important role in regulating actin cytoskeleton remodeling and membrane receptor signaling. While studies using short hairpin RNA (shRNA) have suggested that Abi1 plays a critical role in Bcr-Abl-induced leukemogenesis, the mechanism involved is not clear.

Methods: In this study, we knocked out Abi1 expression in p185-transformed hematopoietic cells using CRISPR/Cas9-mediated gene editing technology.
