The Role of Endothelial L-PGDS in the Pro-Angiogenic and Anti-Inflammatory Effects of Low-Dose Alcohol Consumption.

Cells

December 2024

Department of Cellular Biology and Anatomy, LSU Health Shreveport, Shreveport, LA 71103, USA.

Light alcohol consumption (LAC) may reduce the incidence and improve the prognosis of ischemic stroke. Recently, we found that LAC promotes cerebral angiogenesis and inhibits early inflammation following ischemic stroke. In addition, LAC upregulates lipocalin-type prostaglandin D2 synthase (L-PGDS) in the brain.

Background: Shunted hydrocephalus patients are at an inherent risk of developing chronic subdural hematomas (cSDHs) from overdrainage. The preliminary results of three much-anticipated clinical trials (STEM, EMBOLISE, MAGIC-MT) have recently been presented, showing efficacy of middle meningeal artery embolization (MMA-E) in reducing observational failure and the need for reoperation in non-shunted patients, but the effect of this procedure in shunted patients remains to be further investigated. In this series, we present our institution's experience with MMA-E in shunted normal pressure hydrocephalus patients in comparison to standard of care (=SOC).

The dorsomedial hypothalamus (DMH) receives inputs from the preoptic area (POA), where ambient temperature mediates physiological adaptations of energy expenditure and food intake. Warm-activated POA neurons suppress energy expenditure via brown adipose tissue (BAT) projecting neurons in the dorsomedial hypothalamus/dorsal hypothalamic area (dDMH/DHA). Our earlier work identified leptin receptor (Lepr)-expressing, BAT-projecting dDMH/DHA neurons that mediate metabolic leptin effects.

Validation of Therapeutic Agent Conjugation to Polyvinyl Alcohol-Coated Medical Devices.

J Vis Exp

November 2024

Department of Molecular and Cellular Physiology, LSU Health Shreveport.

Article Synopsis
  • Protein-based therapeutics face challenges with delivery and site-specific action, but our approach involves covalently attaching these proteins to medical devices for targeted delivery.
  • We studied the binding of glucagon-like peptide-2 (GLP-2) to vaginal and intestinal expansion sleeves, using chemically reactive surfaces to enable effective binding of this therapeutic agent.
  • Our results showed that about 44% of the applied GLP-2 could be immobilized on the devices, allowing for lower doses to achieve similar therapeutic effects compared to traditional systemic administration, while minimizing side effects.

Aim: To identify some novel fatty acid hydrolase (FAAH) inhibitors that may contribute to the treatment of Alzheimer's disease (AD).

Methods: In-silico pharmacophore modelling including ligand-based pharmacophore modelling, virtual screening, molecular docking, molecular dynamics modelling, density functional theory and in-silico pharmacokinetics and toxicological studies were employed for the retrieving of novel FAAH inhibitors. Further, these compounds were evaluated for FAAH inhibitory activity using an in vitro enzymatic assay, and later, an in vivo streptozotocin (STZ)-induced AD model was examined in mice.

Objectives: This investigation aimed to examine the effects of the COVID-19 pandemic on treatment delays and the severity of initial disease presentation in cholesteatoma patients treated in the prepandemic and pandemic periods.

Methods:  This retrospective cohort study was of patients who underwent primary surgical management of cholesteatoma between October 2018 and December 2021, split between the prepandemic (October 2018 to February 2020) and pandemic (April 2020 to December 2021) time periods. Data collected included time from referral to otology clinic visit, time of diagnosis, and time of surgical interventions.

Plants host an array of microbial symbionts, including both bacterial and fungal endophytes located within their roots. While bacterial and fungal endophytes independently alter host plant growth, response to stress and susceptibility to disease, their combined effects on host plants are poorly studied. To tease apart interactions between co-occurring endophytes on plant growth, morphology, physiology, and survival we conducted a greenhouse experiment.

Protein tyrosine phosphatase 1b (PTP1b) is a member of the protein tyrosine phosphatase (PTP) enzyme group and encoded as PTP1N gene. Studies have evidenced an overexpression of the PTP1b enzyme in metabolic syndrome, anxiety, schizophrenia, neurodegeneration, and neuroinflammation. PTP1b inhibitor negatively regulates insulin and leptin pathways and has been explored as an antidiabetic agent in various clinical trials.

A functional vascular access (VA) is of paramount importance to patients on hemodialysis therapy. While arteriovenous fistula (AVF) remains the preferred VA, their long-term patency is unpredictable. A dysfunctional VA contributes to a high morbidity rate, an increased susceptibility to major adverse cardiovascular events, recurrent hospitalization, and a poor quality of life.

The benthic pennate diatom Nitzschia navis-varingica, known for producing domoic acid (DA) and its isomers, is widely distributed in the Western Pacific (WP) region. To investigate the genetic differentiation and gene flow patterns among the populations in the WP, the genetic diversity of 354 strains of N. navis-varingica was analysed using two nuclear-encoded rDNA loci: the large subunit rDNA (LSU rDNA) and the internal transcribed spacer 2 (ITS2).

Yessotoxin is one of the shellfish toxins leading to mussel farm closures in the Adriatic Sea of Italy. Two putative Gonyaulax spinifera strains GSA0501 and GSA0602 are known as yessotoxins producers, but their identities have remained elusive since 2005. To address this gap, we established five Gonyaulax strains by incubating sediments from the Adriatic Sea and subsequently isolating single cells.

Addressing adolescent mental health difficulties often begins by first correctly identifying students who are at risk when using universal mental health screeners in the school setting. A comprehensive conceptualization of mental health may enhance school psychologists' ability to effectively understand the mental health of students they serve. The dual-factor model of mental health posits a more holistic approach to mental health by capturing subjective-wellbeing scores alongside psychopathology.
