Manzamine A: A Promising Marine-Derived Cancer Therapeutic for Multi-targeted Interactions with E2F8, SIX1, AR, GSK-3β, and V-ATPase - A Systematic Review.

Manzamine A, a natural compound derived from various sponge genera, features a β-carboline structure and exhibits a range of biological activities, including anti-inflammatory and antimalarial effects. Its potential as an anticancer agent has been explored in several tumor models, both in vitro and in vivo, showing effects through mechanisms such as cytotoxicity, regulation of the cell cycle, inhibition of cell migration, epithelial-to-mesenchymal transition (EMT), autophagy, and apoptosis through multi-target interactions of E2F transcriptional factors, ribosomal S6 kinases, androgen receptor (AR), SIX1, GSK-3β, V-ATPase, and p53/p21/p27 cascades. This systematic review evaluates existing literature on the potential application of this marine alkaloid as a novel cancer therapy, highlighting its promising ability to inhibit cancer cell growth while causing minimal side effects.

Green Tea Polyphenol Epigallocatechin Gallate Interactions with Copper-Serum Albumin.

Epigallocatechin gallate (EGCg), an abundant phytochemical in green tea, is an antioxidant that also binds proteins and complex metals. After gastrointestinal absorption, EGCg binds to serum albumin in the hydrophobic pocket between domains IIA and IIIA and overlaps with the Sudlow I site. Serum albumin also has two metal binding sites, a high-affinity N-terminal site (NTS) site that selectively binds Cu(II), and a low-affinity, less selective multi-metal binding site (MBS).

Preliminary effects of oral ANS-6637, an ALDH2 inhibitor, on cue-induced craving, safety and alcohol consumption among adults with alcohol use disorder: a proof-of-concept, randomized, human laboratory trial.

Aims: We evaluated the safety, efficacy, and patient adherence to oral ANS-6637, a selective, reversible inhibitor of aldehyde dehydrogenase 2 (ALDH2), for treating alcohol use disorder (AUD).

Methods: A 3-arm, double-blind, randomized, proof-of-concept human laboratory study embedded in a 5-week multisite clinical trial tested 200 mg and 600 mg daily doses of ANS-6637 compared to placebo in treatment-seeking adults with AUD. After 1 week of medication, participants completed an alcohol cue reactivity session.

Understanding the Role of Trust in Healthcare and Intentions to Pursue Live Donor Kidney Transplant Among African American End Stage Kidney Disease Patients.

African Americans (AAs) with end-stage kidney disease (ESKD) experience significant barriers to accessing living donor kidney transplantation (LDKT), largely due to individual and systemic factors, including a lack of trust in healthcare systems resulting from a legacy of and continued experiences with medical racism. This cross-sectional study analyzed survey data from 416 AA patients with ESKD undergoing transplant evaluation in 2019-2023 at two kidney transplant centers in the Southeast United States, examining whether trust (specifically trust in kidney doctors, hospitals, and healthcare) modifies the relationship between attitudes towards LDKT and behavioral intentions to discuss LDKT with family and friends. Multivariable analyses revealed significant interactions.

Trends in use of tobacco and cannabis across different alcohol consumption levels in the United States, 2010-19.

Aims: People often drink alcohol and use other substances concurrently, increasing the risk of adverse health outcomes. Our aims were to: (i) assess temporal trends in tobacco and/or cannabis use by varying alcohol consumption levels and (ii) identify associated factors of polysubstance use in high-risk alcohol users.

Methods: We conducted a repeated cross-sectional study combining 2010-19 U.

Novel Application of Skills for Psychological Recovery as an Early Intervention for Posttraumatic Stress Disorder, Depression, and Alcohol Misuse in Survivors of Recent Sexual Assault: A Case Series.

Skills for Psychological Recovery (SPR) is an evidence-informed, early intervention for teaching survivors coping skills in the aftermath of recent disasters. Although SPR has not been tested following recent sexual assault, there is theoretical support for applying SPR to the needs of recent sexual assault survivors. The current study is the first to describe the application of SPR among survivors of recent sexual assault.

Enhancement of detoxification of xenobiotic aromatic amine dyes by N-acetyltransferase 1 (NAT1) enzyme on human keratinocytes cells through structural modification.

The metabolic conversion of aromatic amines to N-acetylated forms in skin and keratinocytes depends on N-acetyltransferase-1 (NAT1). Common hair color ingredient such as para-phenylenediamine (PPD) causes allergic contact dermatitis. We explored how different electronic substituents on PPD aided NAT1 enzyme biotransform oxidative arylamine (AA) compounds G1-G13 by N-acetylation, NAT-1 activity assays, metabolism, and in vitro clearance investigations in human keratinocytes, while identifying NAT-1 protein levels by Western blot and qRT-PCR.

We're in This Together: A Case Study of the Concurrent Delivery of Prolonged Exposure Therapy to Intimate Partners With PTSD.

Research on the links between intimate relationships and PTSD and the treatments for PTSD tend to be limited to couples in which only one partner within the dyad has PTSD. No investigations, to our knowledge, have empirically examined the simultaneous provision of evidence-based PTSD treatment to both partners in an intimate relationship diagnosed with PTSD. The current case study describes two partners in a different-sex relationship, both diagnosed with current PTSD, who received individual Prolonged Exposure (PE) therapy at the same time as part of a larger randomized clinical trial.

Ranking of Health Problems and Prioritization of Cancer Education Topics by African American Communities in South Carolina.

Despite landmark breakthroughs in cancer research, African American adults (AA) bear the highest cancer burden compared to other racial groups in the United States (US). AA adults have twice the likelihood of dying from prostate and uterine cancers compared to White adults, suggesting that there are fundamental issues yet to be addressed when developing and implementing cancer-preventative programs for AA communities. Community-based participatory research (CBPR) empowers community members to identify and prioritize their health problems and preferred strategies to tackle these issues.

Disparities in Access to Valganciclovir Cytomegalovirus Prophylaxis in High-Risk African American Kidney Transplant Patients.

Background: While access and outcomes disparities for African American (AA) kidney transplant recipients are documented, there are limited studies assessing medication access disparities in transplantation. Cytomegalovirus (CMV) causes severe complications for transplant recipients, and we aimed to understand differences in access to CMV prophylaxis valganciclovir and its impact on CMV infection rates in AA transplant recipients.

Methods: This single-center, retrospective longitudinal cohort study examined high-risk (CMV serostatus D+/R-) adult kidney transplant recipients between June 1, 2010, and May 31, 202, through EMR abstraction.

CD38 Inhibitor 78c Attenuates Pro-Inflammatory Cytokine Expression and Osteoclastogenesis in Macrophages.

CD38, a nicotinamide adenine dinucleotide (NAD) glycohydrolase, increases during infection or inflammation. Therefore, we aimed to evaluate the effects of a CD38 inhibitor (78c) on NAD levels, IL-1β, IL-6, TNF-α cytokine expressions, and osteoclastogenesis. The results show that treatment with 78c on murine BMMs dose-dependently reduced CD38, reversed the decline of NAD, and inhibited IL-1β, IL-6, and TNF-α pro-inflammatory cytokine levels induced by oral pathogen () or () or by advanced glycation end products (AGEs).

Event-level effects of alcohol, cannabis, and simultaneous alcohol and cannabis use on bystander intentions in response to hypothetical situations among college women.

Bystanders can play an important role in preventing alcohol-related harm (e.g., unintentional injury) or sexual aggression.

Increasing the visibility of Asian American, Native Hawaiian, and Pacific Islanders in substance use research: A call to action.

Asian Americans, Native Hawaiians, and Pacific Islanders (AA/NH/PI) are one of the most diverse racial and ethnic groups in the U.S., encompassing origins from over forty countries.

Multicenter Clinical Performance Evaluation of the NeuMoDx™ CT/NG Assay 2.0.

Background: Given the continued increases in rates of both Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infection, additional diagnostic assays may be useful in increasing access to testing for these sexually transmitted infections. We evaluated the performance of the NeuMoDx™ CT/NG Assay 2.0 on the NeuMoDx-96 and NeuMoDx-288 Molecular Systems.

Latent Profiles of Drinking Motives Among Trauma-Exposed Combat Veterans and Civilians: A Comparative Investigation.

Trauma exposure and drinking motives (e.g., social, enhancement, coping) are both associated with increased alcohol use and related problems.

Alcohol use and cannabis craving in daily life: Sex differences and associations among young adults.

Background: Alcohol and cannabis are commonly used together by young adults. With frequent pairings, use of one substance may become a conditioned cue for use of a second, commonly co-used substance. Although this has been examined for alcohol and cannabis in laboratory conditions and with remote monitoring, no research has examined whether pharmacologically induced cross-substance craving occurs in naturalistic conditions.

Role of Mitochondrial Iron Uptake in Acetaminophen Hepatotoxicity.

Overdose of acetaminophen (APAP) produces fulminant hepatic necrosis. The underlying mechanism of APAP hepatotoxicity involves mitochondrial dysfunction, including mitochondrial oxidant stress and the onset of mitochondrial permeability transition (MPT). Reactive oxygen species (ROS) play an important role in APAP-induced hepatotoxicity, and iron is a critical catalyst for ROS formation.

Role of oxytocin and vasopressin in alcohol use disorder.

Published works highlight the role of neuropeptides in both the development and treatment of AUD. Closely related hypothalamic neuropeptides, oxytocin (OT) and vasopressin (VP), initially recognized for their physiological hormone effects, are increasingly acknowledged for their behavioral influences. Studies consistently demonstrate that OT and VP impact alcohol consumption and related behaviors, implicating them in the neurobiology of addiction.

Characterizing Individuals Who Elect and Decline Opioid Overdose Education and Naloxone Distribution to Tailor Programs and Expand Impact.

Background: In response to the opioid epidemic, federal agencies have stressed the importance of targeted naloxone distribution through avenues such as Opioid Overdose Education and Naloxone Distribution (OEND). OEND effectively reduces mortality by training laypersons to respond to overdose situations. Despite demonstrated effectiveness, OEND remains underutilized.

Combination treatment with cilostazol and isosorbide mononitrate attenuates microemboli-mediated vascular cognitive impairment and improves imaging and plasma biomarkers in diabetic rats.

Diabetes is a major risk factor for all types of dementia. The underlying reasons are not fully understood, and preventive therapeutic strategies are lacking. Previously we have shown that diabetic but not control rats developed a progressive cognitive decline in a microemboli (ME) model of vascular contributions to cognitive impairment & dementia (VCID).

Enhanced Fear Extinction Through Infralimbic Perineuronal Net Digestion: The Modulatory Role of Adolescent Alcohol Exposure.

Perineuronal nets (PNNs) are specialized components of the extracellular matrix that play a critical role in learning and memory. In a Pavlovian fear conditioning paradigm, degradation of PNNs affects the formation and storage of fear memories. This study examined the impact of adolescent intermittent ethanol (AIE) exposure by vapor inhalation on the expression of PNNs in the adult rat prelimbic (PrL) and infralimbic (IfL) subregions of the medial prefrontal cortex.
