Deletion of metal transporter Zip14 reduces major histocompatibility complex II expression in murine small intestinal epithelial cells.

Documented worldwide, impaired immunity is a cardinal signature resulting from loss of dietary zinc, an essential micronutrient. A steady supply of zinc to meet cellular requirements is regulated by an array of zinc transporters. Deletion of the transporter Zip14 (Slc39a14) in mice produced intestinal inflammation.

Severe aplastic anemia with acquired X chromosome clonality as a sole abnormality.

This case is a rare presentation of severe aplastic anemia in a 31-year-old male with acquired clonality of the X chromosome as the sole cytogenetic abnormality. This abnormality has not been reported to our knowledge, and the significance of this finding remains unclear. Comprehensive diagnostic workup included bone marrow biopsy, cytogenetic analysis, and Next-Generation sequencing, which revealed no tier I/II variants typically associated with clonal hematopoietic disorders.

Associations between genetic variations in oxytocin pathway genes and hippocampal volume: Insights from the UK Biobank.

The role of oxytocin-related genes in social-cognitive function has been previously established, but structural brain mechanisms underlying this link remain poorly understood. Utilizing a substantial dataset from the UK Biobank (N ≈ 30,000), this research determined associations between variations in ten single nucleotide polymorphisms (SNPs) within three oxytocin pathway genes (i.e.

Organizational on-boarding practices and shifts in alcohol misuse among at-risk college recruits.

With a significant proportion of college students in many countries engaging in risky drinking behavior, this study examines the tendency of such young adults to 'mature out' of such behavior in their first year of employment after graduating, and the degree to which three mainstream organizational on-boarding experiences may expedite such 'maturing out'. Focusing on newcomers' experiences with alcohol-oriented job orientation, job empowerment, and organizational efforts to facilitate the development of supportive peer relationships, we test hypotheses regarding the direct effects of time on the change in alcohol misuse among those reporting misuse in college, as well as the degree to which individual on-boarding experiences account for the variance in young adults' maturing out trajectories over the course of their first year of employment. Findings generated from data collected from over 400 young adults over multiple waves offer important theoretical and practical implications regarding how and why particular onboarding tactics may be more or less effective in influencing newcomers' health-related behaviors.

Advancements in Immunity and Dementia Research: Highlights from the 2023 AAIC Advancements: Immunity Conference.

The immune system is a key player in the onset and progression of neurodegenerative disorders. While brain resident immune cell-mediated neuroinflammation and peripheral immune cell (eg, T cell) infiltration into the brain have been shown to significantly contribute to Alzheimer's disease (AD) pathology, the nature and extent of immune responses in the brain in the context of AD and related dementias (ADRD) remain unclear. Furthermore, the roles of the peripheral immune system in driving ADRD pathology remain incompletely elucidated.

A Scoping Review of Observational Research on Cannabis Use for Symptom Management in HIV and Cancer: Implications for Cannabis Nursing.

Background: People with HIV have a higher risk of developing non-AIDS-defining cancers in older age, leading to a significant population living with two conditions, HIV and cancer. There is an increasing interest in cannabis use for symptom management in people with chronic conditions; in 2023, the American Nurses Association officially recognised cannabis nursing as a specialty nursing practice focusing on the care of individuals seeking education/guidance in the therapeutic use of cannabis, supporting the urgency of its research. However, the scientific literature lacks a synthesised review in the focused populations.

The effects of adverse life events on brain development in the ABCD study®: a propensity-weighted analysis.

Longitudinal studies of the effects of adversity on human brain development are complicated by the association of stressful events with confounding variables. To counter this bias, we apply a propensity-weighted analysis of the first two years of The Adolescent Brain Cognitive Development (ABCD) Study® data, employing a machine learning analysis weighted by individuals' propensity to experience adversity. Data included 338 resting-state functional connections from 7190 youth (46% female), divided into a training group (80%) and an independent testing group (20%).

Measurement Error and Methodologic Issues in Analyses of the Proportion of Variance Explained in Cognition.

Existing studies examining the predictive ability of biomarkers for cognitive outcomes do not account for variance due to measurement error, which could lead to under-estimates of the proportion of variance explained. We used data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) (N = 1084) to estimate the proportion of variance explained by Alzheimer's disease (AD) imaging biomarkers in four cognitive outcomes: memory, executive functioning, language, and visuospatial functioning. We compared estimates from standard models that do not account for measurement error, and multilevel models that do account for measurement error.

In vitro impacts of glyphosate on manatee lymphocytes.

Exposure to contaminants, such as the herbicide glyphosate, can suppress protective immune functions. Glyphosate is the herbicide most used worldwide and has been found in the plasma of more than 50 % of the Florida manatees (Trichechus manatus latirostris) and all-year-round in their aquatic environment. Our objectives were to analyze the consequences of glyphosate exposure on their immune responses via T-lymphocyte proliferation assays and transcriptomics.

The effects of moderate prenatal alcohol exposure on performance in object and spatial discrimination tasks by adult male rats.

Exposure to alcohol during pregnancy produces Fetal Alcohol Spectrum Disorders, which in its most severe form is characterized by physical dysmorphology and neurobehavioral alterations. Moderate prenatal alcohol exposure (mPAE) is known to produce deficits in discrimination of spatial locations in adulthood. However, the impact of mPAE on higher-order sensory representations, such as discrimination of perceptually similar stimuli, is currently unknown.

Identification of atypical pediatric diabetes mellitus cases using electronic medical records.

Introduction: There are no established methods to identify children with atypical diabetes for further study. We aimed to develop strategies to systematically ascertain cases of atypical pediatric diabetes using electronic medical records (EMR).

Research Design And Methods: We tested two strategies in a large pediatric hospital in the USA.

The Innate Immune System Surveillance Biomarker p87 in African Americans and Caucasians with Small High-Grade Dysplastic Adenoma [SHiGDA] and Right-Sided Colon Mutations May Explain the Presence of Multiple Cancers Revealing an Important Minority of Patients with Mutations and Colorectal Neoplasia.

Unlabelled: Colorectal cancer (CRC) outcomes in terms of incidence and mortality are significantly worse in African Americans than other Americans. While differences in primary preventions for neoplasia (diet, obesity remediation, aspirin prophylaxis) are being elucidated, genetic mutations affecting premalignant lesions and immune response mechanisms may possibly also explain the increased incidence and mortality, particularly from right-sided disease.

Objective: Our team therefore examined colonic segments seeking to test the hypothesis that the immune response and somatic genetic profiles of the colonic anatomic segments may vary and thus account for variations in neoplasia risk among the various colonic segments revealing an antigenic relationship with precancerous lesions.

Frontal GABA levels associate with musical rhythm production in healthy aging adults.

Changes in neuronal inhibition have been implicated in age-related declines in sensorimotor performance. While indirect evidence suggests that inhibitory mechanisms are also involved in rhythm entrainment, this association has not been tested. Using magnetic resonance spectroscopy, we tested the association between dorsomedial frontal GABA+/H2O concentrations and musical rhythm production in healthy younger (n = 14; 18-35) and older (n = 12; 55-79) adults, hypothesizing that lower GABA+/H2O concentrations would be associated with increased timing error, particularly on more difficult exercises, and intra-individual variability (quantified via mean successive squared difference (MSSD)).

Using Phosphatidylethanol as an Adjunct to Self-Reported Alcohol Use Improves Identification of Liver Fibrosis Risk.

Introduction: Accurate assessment of alcohol use informs prevention and management of liver disease. We examined whether phosphatidylethanol (PEth, an alcohol metabolite) blood concentrations are associated with liver fibrosis risk independently of self-reported alcohol use, among persons with and without HIV.

Methods: We pooled individual-level data from 12 studies from the United States, Russia, Uganda, and South Africa with PEth, Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), and fibrosis-4 (FIB-4) measurements.

Measuring depressive symptoms among Latinos in the US: a psychometric evaluation of the CES-D Boston form.

Purpose: We present a psychometric evaluation of the Center for Epidemiologic Studies Depression Boston Form (CES-D-B) for use with different Latino subgroups as there is inconsistency regarding its performance across subgroups of Latinos, a large and rapidly growing cultural group in the United States.

Methods: We evaluated the reliability and structural validity of the scores generated by the CES-D-B using four distinct Latino samples residing in US: Mexicans, Venezuelans, Cubans, and "other Latinos" (total N = 1033). To further explore structural validity of CES-D-B scores, we conducted measurement invariance analyses across different countries of origin, gender groups, educational levels, and languages of assessment (English, Spanish).

Extracellular matrix protein 1 binds to connective tissue growth factor against liver fibrosis and ductular reaction.

Background: Extracellular matrix protein 1 (ECM1) can inhibit TGFβ activation, but its antifibrotic action remains largely unknown. This study aims to investigate ECM1 function and its physical interaction with the profibrotic connective tissue growth factor (CTGF) in fibrosis and ductular reaction (DR).

Methods: Ecm1 knockouts or animals that ectopically expressed this gene were subjected to induction of liver fibrosis and DR by feeding 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) or α-naphthyl-isothiocyanate (ANIT).

Methods: The 8-step Walker and Avant framework guided the concept analysis of psychosocial distress tailored to this patient population.

Sexual Misconduct by Board Certified Family Physicians.

Purpose: Sexual misconduct by physicians is a consequential violation of patient trust. The purpose of this study was to determine the frequency and patterns of sexual misconduct by physicians certified by the American Board of Family Medicine (ABFM).

Methods: We described a cohort of current or formerly ABFM certified physicians ("Diplomates") disciplined for sexual misconduct in 2016 to 2022.

Isoform-level expression of the constitutive androstane receptor (CAR or NR1I3) transcription factor better predicts the mRNA expression of the cytochrome P450s in human liver samples.

Many factors cause inter-person variability in the activity and expression of liver cytochrome P450 (CYP) drug-metabolizing enzymes, leading to variable drug exposure and treatment outcomes. Several liver-enriched transcription factors (TFs) are associated with CYP expression, with estrogen receptor alpha (ESR1) and constitutive androstane receptor (CAR or NR1I3) being the two top factors. ESR1 and NR1I3 undergo extensive alternative splicing that results in numerous splice isoforms, but how these splice isoforms associate with CYP expression is unknown.
