Sex-specific effects on the heart from combined exposure to simulated galactic cosmic radiation and hindlimb unloading.

Future long duration space missions will expose astronauts to higher doses of galactic cosmic radiation (GCR) than those experienced on the international space station. Recent studies have demonstrated astronauts may be at risk for cardiovascular complications due to increased radiation exposure and fluid shift from microgravity. However, there is a lack of direct evidence on how the cardiovascular system is affected by GCR and microgravity since no astronauts have been exposed to exploratory mission relevant GCR doses.

Galactic cosmic ray environment predictions for the NASA BioSentinel Mission, part 2:Post-mission validation.

The BioSentinel CubeSat was deployed on the Artemis-I mission in November 2022 and has been continuously transmitting physical measurements of the space radiation environment since that time. Just before mission launch, we published computational model predictions of the galactic cosmic ray exposure expected inside BioSentinel for multiple locations and configurations. The predictions utilized models for the ambient galactic cosmic ray environment, radiation physics and transport, and BioSentinel geometry.

The hypercapnic environment on the International Space Station (ISS): A potential contributing factor to ocular surface symptoms in astronauts.

With increasing advancements and efforts towards space exploration, there is a pressing need to understand the impacts of spaceflight on astronauts' health. Astronauts have reported signs and symptoms of dry eye disease upon traveling to the International Space Station (ISS), thus necessitating an evaluation of the factors that contribute to the onset of spaceflight associated dry eye disease. Prior literature describes the hypercapnic environment of the ISS; however, the link between the high CO levels and astronauts' symptoms of dry eye disease remains unexplored.

Patient Characteristics, Management and Long-term Outcomes of Patients with Cardiogenic Shock at a Large Safety Net Hospital.

Data regarding cardiogenic shock (CS) from safety-net hospitals serving socioeconomically-disadvantaged patients are limited. In addition, little is known regarding long-term outcomes and management of heart failure-related CS (HF-CS), a population potentially especially vulnerable to adverse social determinants of health (SDOH). A single-center retrospective cohort study of patients with Stage C, D, or E CS at a public safety-net hospital between 2017-2023 was performed.

Diffusion-weighted arterial spin labeling MRI to investigate mannitol-induced blood brain barrier disruption.

Purpose: Diffusion-weighted arterial spin labeling (DW-ASL) MRI has been proposed to determine the rate of water exchange (K) across the blood brain barrier (BBB). This study aims to further evaluate K MRI by comparing it with standard dynamic contrast-enhanced (DCE) MRI and histology in association with mannitol-induced disruption of the BBB.

Methods: DW-ASL was measured using a multiple b-value MRI protocol in normal rats at three post-labeling delays (N = 19), before and after intra-carotid injection of mannitol to disrupt BBB in one hemisphere (N = 13).

Baseline and outcome stereoacuity of children with anisometropic amblyopia undergoing dichoptic amblyopia treatment.

Background: One rationale for dichoptic amblyopia therapy is that it may promote recovery of binocular function. Yet data on binocular outcomes in anisometropic amblyopia following dichoptic therapy are sparse. We report factors associated with pre- and post-treatment binocular function in anisometropic amblyopia, and examine binocular function in children who recover normal visual acuity compared to those with residual amblyopia.

Impacto - A single-arm open-label pilot trial of a digital-based integrated smoking cessation program for Spanish-speaking Hispanic individuals who smoke: Development, feasibility, engagement, and clinical outcomes.

Introduction: Hispanic/Latinx (hereafter Hispanic) individuals who smoke have challenges in quitting and a disproportionate risk of smoking-related health problems when compared to the general population. The smoking inequalities among the Hispanic population are influenced by limited treatment access and chronic stress exposure (e.g.

Rhythm is essential: Unraveling the relation between the circadian clock and cancer.

Physiological processes such as the sleep-wake cycle, metabolism, hormone secretion, neurotransmitter release, sensory capabilities, and a variety of behaviors, including sleep, are controlled by a circadian rhythm adapted to 24-hour day-night periodicity. Disruption of circadian rhythm may lead to the risks of numerous diseases, including cancers. Several epidemiological and clinical data reveal a connection between the disruption of circadian rhythms and cancer.

Cytoplasmic expression of trans-active response DNA-binding protein-43 in aged mice display hippocampal sclerosis-like degeneration and neuronal loss with reduced lifespan.

Trans-active response DNA-binding protein-43 (TDP-43) is the major pathological protein in motor neuron disease and TDP-43 pathology has been described in the brains of up to 50% of patients with Alzheimer disease (AD). Hippocampal sclerosis of aging (HS-A), an age-related neuropathology characterized by severe neuronal loss and gliosis in CA1 and/or subiculum, is found in ∼80% of cases that are positive for phosphorylated TDP-43. HS-A is seen as a co-pathology in cases with AD, limbic-predominant age-related TDP-43 encephalopathy neuropathologic changes (LATE-NC), and frontotemporal degeneration.

Characterizing the relationship between personality dimensions and psychosis-specific clinical characteristics.

Background: Past studies associating personality with psychosis have been limited by small nonclinical samples and a focus on general symptom burden. This study uses a large clinical sample to examine personality's relationship with psychosis-specific features and compare personality dimensions across clinically and neurobiologically defined categories of psychoses.

Methods: A total of 1352 participants with schizophrenia, schizoaffective disorder, and bipolar with psychosis, as well as 623 healthy controls (HC), drawn from the Bipolar-Schizophrenia Network for Intermediate Phenotypes (BSNIP-2) study, were included.

Revolutionizing acute myeloid leukemia treatment: a systematic review of immune-based therapies.

The established protocol for the management of acute myeloid leukemia (AML) has traditionally involved the administration of induction chemotherapy, followed by consolidation chemotherapy, and subsequent allogeneic stem cell transplantation for eligible patients. However, the prognosis for individuals with relapsed and refractory AML remains unfavorable. In response to the necessity for more efficacious therapeutic modalities, targeted immunotherapy has emerged as a promising advancement in AML treatment.

A Comprehensive Atlas of AAV Tropism in the Mouse.

Gene therapy with Adeno-Associated Virus (AAV) vectors requires knowledge of their tropism within the body. Here we analyze the tropism of ten naturally occurring AAV serotypes (AAV3B, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAVrh8, AAVrh10 and AAVrh74) following systemic delivery into male and female mice. A transgene expressing ZsGreen and Cre recombinase was used to identify transduction in a cell-dependent manner based on fluorescence.

Global metabolomic alterations associated with endocrine-disrupting chemicals among pregnant individuals and newborns.

Background: Gestational exposure to non-persistent endocrine-disrupting chemicals (EDCs) may be associated with adverse pregnancy outcomes. While many EDCs affect the endocrine system, their effects on endocrine-related metabolic pathways remain unclear. This study aims to explore the global metabolome changes associated with EDC biomarkers at delivery.

Encorafenib, cetuximab and chemotherapy in BRAF-mutant colorectal cancer: a randomized phase 3 trial.

Encorafenib + cetuximab (EC) is approved for previously treated BRAF V600E-mutant metastatic colorectal cancer (mCRC) based on the BEACON phase 3 study. Historically, first-line treatment of BRAF V600E-mutant mCRC with chemotherapy regimens has had limited efficacy. The phase 3 BREAKWATER study investigated EC+mFOLFOX6 versus standard of care (SOC) in patients with previously untreated BRAF V600E mCRC.

Multidimensional library for the improved identification of per- and polyfluoroalkyl substances (PFAS).

As the occurrence of human diseases and conditions increase, questions continue to arise about their linkages to chemical exposure, especially for per-and polyfluoroalkyl substances (PFAS). Currently, many chemicals of concern have limited experimental information available for their use in analytical assessments. Here, we aim to increase this knowledge by providing the scientific community with multidimensional characteristics for 175 PFAS and their resulting 281 ion types.

The 40S ribosomal subunit recycling complex modulates mitochondrial dynamics and endoplasmic reticulum - mitochondria tethering at mitochondrial fission/fusion hotspots.

The 40S ribosomal subunit recycling pathway is an integral link in the cellular quality control network, occurring after translational errors have been corrected by the ribosome-associated quality control (RQC) machinery. Despite our understanding of its role, the impact of translation quality control on cellular metabolism remains poorly understood. Here, we reveal a conserved role of the 40S ribosomal subunit recycling (USP10-G3BP1) complex in regulating mitochondrial dynamics and function.

Clinically Meaningful Upstaging and Upgrading in Favorable Intermediate-Risk Radical Prostatectomy Patients.

Introduction: In NCCN favorable intermediate-risk (FIR) prostate cancer (PCa) patients treated with radical prostatectomy (RP), we tested the effect of upstaging and upgrading on cancer-specific mortality (CSM).

Methods: Within the SEER database (2010-2021), upstaging (≥pT3a or pN1) and upgrading (ISUP ≥3) rates in FIR RP patients were tabulated. Kaplan-Meier (KM) plots and multivariable Cox-regression models (CRMs) were fitted.
