Investigating the Mechanism of Neurotoxic Effects of PFAS in Differentiated Neuronal Cells through Transcriptomics and Lipidomics Analysis.

Per- and polyfluorinated alkyl substances (PFAS) are pervasive environmental contaminants that bioaccumulate in tissues and pose risks to human health. Increasing evidence links PFAS to neurodegenerative and behavioral disorders, yet the underlying mechanisms of their effects on neuronal function remain largely unexplored. In this study, we utilized SH-SY5Y neuroblastoma cells, differentiated into neuronal-like cells, to investigate the impact of six PFAS compounds─perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), perfluorodecanoic acid (PFDA), perfluorodecanesulfonic acid (PFDS), 8:2 fluorotelomer sulfonate (8:2 FTS), and 8:2 fluorotelomer alcohol (8:2 FTOH)─on neuronal health.

A Pharmacokinetic and Bioavailability Study of Phlorotannins Following Intravenous and Oral Administration in Sprague-Dawley Rats.

This study examines the pharmacokinetics and bioavailability of phlorotannins from in rats following intravenous and oral administration. Known for their potent antioxidant, anti-inflammatory and many other bioactivities, these phlorotannins, particularly dieckol, 8,8'-bieckol, and phlorofucofuroeckol-A (PFF-A), were analyzed using high-performance liquid chromatography coupled with tandem mass spectrometry. Intravenous administration at 10 mg/kg allowed detectability in plasma for up to 36 h for dieckol and 8,8'-bieckol, but only 2 h for PFF-A.

Purpose: To determine the efficacy of nurse-delivered brief behavioral treatment for insomnia (BBTI) compared to an attention control, in a heterogeneous sample of cancer survivors to reduce insomnia symptom severity.

Methods: We recruited 132 participants from cancer care clinics, who had an Insomnia Severity Index (ISI) score ≥ 8. Participants were randomized into two groups: an experimental BBTI group and a healthy eating attention control group.

Unconventional Anomalous Hall Effect Driven by Self-Intercalation in Covalent 2D Magnet CrTe.

Covalent 2D magnets such as CrTe, which feature self-intercalated magnetic cations located between monolayers of transition-metal dichalcogenide material, offer a unique platform for controlling magnetic order and spin texture, enabling new potential applications for spintronic devices. Here, it is demonstrated that the unconventional anomalous Hall effect (AHE) in CrTe, characterized by additional humps and dips near the coercive field in AHE hysteresis, originates from an intrinsic mechanism dictated by the self-intercalation. This mechanism is distinctly different from previously proposed mechanisms such as topological Hall effect, or two-channel AHE arising from spatial inhomogeneities.

Historical Perspective of Allogeneic Hematopoietic Stem Cell Transplantation for Multiple Myeloma.

Background: Advances in novel therapies have improved outcomes for multiple myeloma (MM) patients and the use of allo-SCT has decreased. Current guidelines no longer support allo-SCT as consolidation therapy for newly diagnosed MM, even in high-risk cases.

Summary: Allo-SCT is now typically considered only within clinical trials for young, high-risk patients with relapsed or refractory MM (RRMM).

Self-Protection in the Social Context: A Daily-Level Examination of Young Adult Women's Perceived Need for and Engagement in Sexual Assault Protective Behavioral Strategies.

Objective: Young adult women naturalistically engage in sexual assault protective behavioral strategies (SA-PBS) in an effort to reduce their risk of sexual assault. Despite well-documented sociocontextual risks for sexual assault, it remains largely unknown whether and how social contexts influence SA-PBS use. The present study characterized relations of women's alcohol use and interpersonal contexts with SA-PBS engagement across social events, framed according to Routine Activity Theory.

State Tracking in Nonadiabatic Molecular Dynamics Using Only Forces and Energies.

A new algorithm for the identification of unavoided (trivial) crossings in nonadiabatic molecular dynamics calculations is reported. The approach does not require knowledge of wave functions or wave function time overlaps and uses only information on state energies and gradients. In addition, a simple phase consistency correction algorithm for time-derivative nonadiabatic couplings is proposed for situations in which wave function time overlaps are not available.

Intraminority Gay Community Stress and Coping Responses Among Gay and Bisexual Men in Taiwan.

A proportion of gay and bisexual men (GBM) experience worse mental health when they encounter stress from problems within the gay community. This qualitative study examined the dominant standards held in the gay community in Taiwan, the intraminority-community stress experienced by GBM, and the strategies that GBM adopt to cope with such stress. Data from open and in-depth interviews with 26 GBM were subject to reflexive thematic analysis.

Obesity-Specific improvement of lung cancer outcomes and immunotherapy efficacy with metformin.

Background: Pre-clinical cancer studies ascribe promising anticancer properties to metformin. Yet, clinical findings vary, casting uncertainty on its therapeutic value for non-small cell lung cancer (NSCLC) patients. We hypothesized that metformin could benefit obese and overweight patients with NSCLC.

Multi-faceted strategies to advance health equity in colorectal cancer screening in primary care setting: quality improvement project.

Background: The aim of this quality improvement (QI) project was to increase Colorectal Cancer (CRC) screening in patients ages 50-75 years from a baseline of 27-40% within 12 months in a primary care clinic in limited resource communities.

Methods: The multidisciplinary QI-team applied the Plan-Do-Study-Act method and developed stakeholder analysis, an Ishikawa fish bone diagram, a process flow map, and a driver diagram. Major barriers to suboptimal CRC screening included limited health literacy, language preferences, absence of stool test options, and knowledge gaps among patients and providers.

Adaptation of a couples intervention to promote coparenting and reduce hazardous drinking during transition to parenthood.

Introduction: Hazardous drinking by fathers poses a significant risk for negative family interactions and child outcomes. The transition to parenthood may be a time when expectant parents are potentially motivated for health behavior change, suggesting that implementing preventive interventions during this period may be particularly effective. This article provides an overview of the rationale for an innovative prevention strategy incorporating alcohol-use intervention with a family-focused program.

Meta-Analysis of Exposure-Adverse Event Relationships for Antibody-Drug Conjugates.

Antibody-drug conjugates (ADCs) have become a vital class of therapeutics in oncology because of their ability to selectively deliver potent drug molecules to tumor cells. However, ADC-associated toxicities cause high failure rates in the clinic and hinder their full potential. Due to the complex structure and pharmacokinetics of ADCs, it is challenging to identify the drivers of their toxicities.

A general kernel machine regression framework using principal component analysis for jointly testing main and interaction effects: Applications to human microbiome studies.

The effect of a treatment on a health or disease response can be modified by genetic or microbial variants. It is the matter of interaction effects between genetic or microbial variants and a treatment. To powerfully discover genetic or microbial biomarkers, it is crucial to incorporate such interaction effects in addition to the main effects.

Generalized Path Integral Energy and Heat Capacity Estimators of Quantum Oscillators and Crystals Using Harmonic Mapping.

Imaginary-time path integral (PI) is a rigorous tool to treat nuclear quantum effects in static properties. However, with its high computational demand, it is crucial to devise precise estimators. We introduce generalized PI estimators for the energy and heat capacity that utilize coordinate mapping.

Background: Glomerular fibrosis is a tissue damage that occurs within the kidneys of chronic and diabetic kidney disease patients. Effective treatments are lacking, and the mechanism of glomerular damage reversal is poorly understood.

Methods: A mathematical model suitable for hypothesis-driven systems pharmacology of glomerular fibrosis in diabetes was developed from a previous model of interstitial fibrosis.

Decoding derogation: The impact of environmental values and political ideology on the effect of persuasive message about recycle and reuse behaviors.

Although persuasive messages are designed to motivate individuals to engage in intended behaviors, they do not always work. Often, people follow previously established values and ideologies and dismiss persuasive messages. We examine how participants react to a persuasive message related to plastic pollution and how these reactions shape their willingness to recycle and reuse.

Longitudinal association between adolescent sexual identity and sleep quality: The mediating roles of peer victimization and perceived social support.

Objective: Despite growing evidence of disparities in sleep quality between sexual minoritized and heterosexual youth, the reasons for these disparities are not well understood. LGBQ+ adolescents often experience challenging peer relationships, which could negatively impact their sleep quality. The current study examined the prospective relationship between sexual minority status and sleep quality over 12months and evaluated whether peer victimization and social support at 6months mediated this relationship among adolescents.

Associations between the incidence of Fuchs' endothelial corneal dystrophy and menopausal hormone therapy use and exposure to endogenous estrogen.

Objectives: End-stage Fuchs' endothelial corneal dystrophy is a leading cause of corneal blindness, with a higher prevalence in females than in males. Few modifiable risk factors have been identified. We examined associations between menopausal hormone therapy use (never/past/current), duration of hormone therapy use, estimated lifetime exposure to endogenous estrogen, and serum estradiol with incident Fuchs' endothelial corneal dystrophy in a cohort of postmenopausal women.

CRISPR-Cas12a-regulated DNA adsorption on MoS quantum dots: Enhanced enzyme mimics for sensitive colorimetric detection of human monkeypox virus and human papillomavirus DNA.

Diseases caused by viruses, such as monkeypox virus (MPXV) and human papillomavirus (HPV), pose serious threats to human health and safety. Although numerous strategies have been constructed for detecting MPXV and HPV DNA, most methods require either laborious procedures or complicated instruments involving skilled professionals. In this research, a CRISPR-Cas12a-mediated colorimetric detection platform for MPXV and HPV sensing was constructed for the first time by applying probe DNA to reprogram the catalytic properties of molybdenum disulfide quantum dots (MoS QDs).
