Examining Demographic & Socio-Cultural Factors as Predictors of Alcohol Consumption Among African American Male College Students Attending an Urban Historically Black College and University.

Alcohol consumption among college students continues to be a significant public health concern for colleges and universities across the country. However, a preponderance of research primarily included White samples from predominantly white institutions. Unsurprisingly, this practice limits what is known regarding alcohol consumption among African American male college students on historically Black campuses.

Mitochondrial function in lungs of rats with different susceptibilities to hyperoxia-induced acute lung injury.

Adult rats exposed to hyperoxia (>95% O) die from respiratory failure in 60-72 h. However, rats preconditioned with >95% O for 48 h followed by 24 h in room air acquire tolerance of hyperoxia (H-T), whereas rats preconditioned with 60% O for 7 days become more susceptible (H-S). Our objective was to evaluate lung tissue mitochondrial bioenergetics in H-T and H-S rats.

Maternal-Infant Factors in Relation to Extracellular Vesicle and Particle miRNA in Prenatal Plasma and in Postpartum Human Milk.

MicroRNAs (miRNA) in extracellular vesicles and particles (EVPs) in maternal circulation during pregnancy and in human milk postpartum are hypothesized to facilitate maternal-offspring communication via epigenetic regulation. However, factors influencing maternal EVP miRNA profiles during these two critical developmental windows remain largely unknown. In a pilot study of 54 mother-child dyads in the New Hampshire Birth Cohort Study, we profiled 798 EVP miRNAs, using the NanoString nCounter platform, in paired maternal second-trimester plasma and mature (6-week) milk samples.

Evidence for the involvement of keratinocyte-derived microvesicle particles in the photosensitivity associated with xeroderma pigmentosum type A deficiency.

Photosensitivity can be due to numerous causes. The photosensitivity associated with deficiency of xeroderma pigmentosum type A (XPA) has been previously shown to be associated with excess levels of the lipid mediator platelet-activating factor (PAF) generated by the keratinocyte. As PAF has been reported to trigger the production of subcellular microvesicle particles (MVP) due to the enzyme acid sphingomyelinase (aSMase), the goal of these studies was to discern if PAF and aSMase could serve as therapeutic targets for the XPA deficiency photosensitivity.

Wrist extensor pathomechanics: implications for tendon and nerve transfer.

Central and peripheral nervous system lesions may disrupt the intricate balance of the prime movers of the wrist. In spasticity, hyperactive wrist flexors create a flexion moment and, if untreated, can lead to flexion contractures. In patients with C6 spinal cord injury and tetraplegia, the posterior interosseus nerve is typically affected by a complex pattern of upper and/or lower motoneuron lesions causing radial deviation of the wrist due to loss of ulnar deviation actuators.

Protocol for a randomized controlled trial to evaluate a year-long (NICU-to-home) evidence-based, high dose physical therapy intervention in infants at risk of neuromotor delay.

Introduction: Developmental disabilities and neuromotor delay adversely affect long-term neuromuscular function and quality of life. Current evidence suggests that early therapeutic intervention reduces the severity of motor delay by harnessing neuroplastic potential during infancy. To date, most early therapeutic intervention trials are of limited duration and do not begin soon after birth and thus do not take full advantage of early neuroplasticity.

impairs human memory CD4 T cell recognition of M2 but not M1-like macrophages.

Direct recognition of (Mtb)-infected cells is required for protection by CD4 T cells. While impaired T cell recognition of Mtb-infected macrophages was demonstrated in mice, data are lacking for humans. Using T cells and monocyte-derived macrophages (MDMs) from individuals with latent Mtb infection (LTBI), we quantified the frequency of memory CD4 T cell activation in response to autologous MDMs infected with virulent Mtb.

PlmCas12e (CasX2) cleavage of CCR5: impact of guide RNA spacer length and PAM sequence on cleavage activity.

Gene editing using CRISPR/Cas (clustered regularly interspaced palindromic repeats/CRISPR-associated) is under development as a therapeutic tool for the modification of genes in eukaryotic cells. While much effort has focused on CRISPR/Cas9 systems from and , alternative CRISPR systems have been identified from non-pathogenic microbes, including previously unknown class 2 systems, adding to a diverse toolbox of CRISPR/Cas enzymes. The Cas12e enzymes from non-pathogenic Deltaproteobacteria (CasX1, DpeCas12e) and Planctomycetes (CasX2, PlmCas12e) are smaller than Cas9, have a selective protospacer adjacent motif (PAM), and deliver a staggered cleavage cut with a 5-7 nucleotide overhang.

Promoting Evidence-Based Practice: The Influence of Novel Structural Change to Accelerate Translational Rehabilitation.

Objective: To evaluate changes in clinicians' use of evidence-based practice (EBP), openness toward EBP, and their acceptance of organizational changes after a rehabilitation hospital transitioned to a new facility designed to accelerate clinician-researcher collaborations.

Design: Three repeated surveys of clinicians before, 7-9 months, and 2.5 years after transition to the new facility.

Systematic Review and Meta-analysis: Efficacy of Mesalamine in Irritable Bowel Syndrome.

Background & Aims: Some patients with irritable bowel syndrome (IBS) demonstrate low-grade inflammation in the intestine. Mesalamine, which has anti-inflammatory effects, may be an efficacious treatment for IBS, but studies are conflicting. We conducted a systematic review and meta-analysis to assess efficacy and safety of mesalamine in IBS.

CAS12e (CASX2) CLEAVAGE OF CCR5: IMPACT OF GUIDE RNA LENGTH AND PAM SEQUENCE ON CLEAVAGE ACTIVITY.

CRISPR/Cas is under development as a therapeutic tool for the cleavage, excision, and/or modification of genes in eukaryotic cells. While much effort has focused on CRISPR/Cas from (SpCas9) and (SaCas9), alternative CRISPR systems have been identified using metagenomic datasets from non-pathogenic microbes, including previously unknown class 2 systems, adding to a diverse toolbox of gene editors. The Cas12e (CasX1, CasX2) endonucleases from non-pathogenic Deltaproteobacteria (DpeCas12e) and Planctomycetes (PlmCas12e) are more compact than SpCas9, have a more selective protospacer adjacent motif (PAM) requirement, and deliver a staggered cleavage cut with 5-7 base overhangs.

Topical Photodynamic Therapy Generates Bioactive Microvesicle Particles: Evidence for a Pathway Involved in Immunosuppressive Effects.

Although effective in treating actinic damage, topical photodynamic therapy (PDT) has been shown to be immunosuppressive through unknown mechanisms, which could potentially limit its effectiveness. Multiple types of environmental stressors, including PDT, can produce the immunosuppressive lipid mediator platelet-activating factor (PAF). Because PAF can produce subcellular microvesicle particles (MVPs), these studies tested whether PDT can generate PAF and MVP release and whether these are involved in PDT-induced immunosuppression.

Pediatric dentists' participation in advocacy and acceptance of new medicaid children in clinical practice.

Introduction: Advocacy involves promoting a noble cause or voicing on behalf of a program, policy, or population group. Previous literature shows that dentists who provide services to Medicaid-enrolled, underserved, and vulnerable children are more compassionate than those who do not.

Aim: To explore the association between pediatric dentists' (PDs) participation in various advocacy-related activities (ARAs) and their monthly acceptance of new Medicaid-enrolled children in their clinical practice to provide dental care services.

Defective bone repletion in aged Balb/cBy mice was caused by impaired osteoblastic differentiation.

Introduction: This study was undertaken to gain mechanistic information about bone repair using the bone repletion model in aged Balb/cBy mice.

Materials And Methods: one month-old (young) mice were fed a calcium-deficient diet for 2 weeks and 8 month-old (adult) and 21-25 month-old (aged) female mice for 4 weeks during depletion, which was followed by feeding a calcium-sufficient diet for 16 days during repletion. To determine if prolonged repletion would improve bone repair, an additional group of aged mice were repleted for 4 additional weeks.

Wilkie's Syndrome following Chemotherapy: A Case Report and a Review of Literature.

Superior mesenteric artery (SMA) syndrome is a rare etiology of upper gastrointestinal obstruction. The measured angle between the SMA and the aorta is typically between 38 and 65° and maintained by mesenteric fat. Excessive fat loss can lead to intestinal obstruction due to an exaggerated acute angularity of the SMA, compressing the third part of the duodenum.

Optic Perineuritis Presenting as the Initial Manifestation of Central Nervous System Involvement in Rai Stage 0 Chronic Lymphocytic Leukemia.

Background: To describe the first case of optic perineuritis because of meningeal involvement of early stage chronic lymphocytic leukemia (CLL).

Methods: A case report and review of the literature.

Results: A case of unilateral optic neuropathy associated with enhancement of the optic nerve sheath is described in a patient with a prior 2-year history of Rai Stage 0 CLL.

Moderation of buprenorphine therapy for cocaine dependence efficacy by variation of the Prodynorphin gene.

Purpose: The aim of this secondary analysis was to identify prodynorphin (PDYN) genetic markers moderating the therapeutic response to treatment of cocaine dependence with buprenorphine/naloxone (Suboxone®; BUP).

Methods: Cocaine-dependent participants (N = 302) were randomly assigned to a platform of injectable, extended-release naltrexone (XR-NTX) and one of three daily medication arms: 4 mg BUP (BUP4), 16 mg BUP (BUP16), or placebo (PLB) for 8 weeks (Parent Trial Registration: Protocol ID: NIDA-CTN-0048, Clinical Trials.gov ID: NCT01402492).

In-Hospital Cardiac Arrest Survival in the United States During and After the Initial Novel Coronavirus Disease 2019 Pandemic Surge.

Background: Recent reports on challenges in resuscitation care at hospitals severely affected by the novel coronavirus disease 2019 (COVID-19) pandemic raise questions about how the pandemic affected outcomes for in-hospital cardiac arrest throughout the United States.

Methods: Within Get With The Guidelines-Resuscitation, we conducted a retrospective cohort study to compare in-hospital cardiac arrest survival during the presurge (January 1-February 29), surge (March 1-May 15) and immediate postsurge (May 16-June 30) periods in 2020 compared to 2015 to 2019. Monthly COVID-19 mortality rates for each hospital's county were categorized, per 1 000 000 residents, as low (0-10), moderate (11-50), high (51-100), or very high (>100).

Evidence for microvesicle particles in UVB-mediated IL-8 generation in keratinocytes.

Recent studies have implicated bioactive microvesicle particles (MVP) in the keratinocyte response to many environmental stressors, in partricular ultraviolet B radiation (UVB). The generation of MVP in response to UVB involves the Platelet-activating factor receptor (PAFR) and the enzyme acid sphingomyelinase (aSMase). As UVB generates some cytokines such as interleukin-8 (IL-8) in a PAFR-dependent manner, one question is if the production and release of IL-8 and MVP could be linked.

Depolarized mitochondrial membrane potential and protection with duroquinone in isolated perfused lungs from rats exposed to hyperoxia.

Dissipation of mitochondrial membrane potential (Δψ) is a hallmark of mitochondrial dysfunction. Our objective was to use a previously developed experimental-computational approach to estimate tissue Δψ in intact lungs of rats exposed to hyperoxia and to evaluate the ability of duroquinone (DQ) to reverse any hyperoxia-induced depolarization of lung . Rats were exposed to hyperoxia (>95% O) or normoxia (room air) for 48 h, after which lungs were excised and connected to a ventilation-perfusion system.

Ultraviolet B Irradiation Alters the Level and miR Contents of Exosomes Released by Keratinocytes in Diabetic Condition.

Ultraviolet B (UVB) stimulates the generation of extracellular vesicles, which elicit systemic effects. Here, we studied whether UVB affects the release and microRNA (miR) content of keratinocyte exosomes (EXs) in diabetic conditions. In vitro, we examined the UVB effects on affecting EX release from keratinocyte HaCaT cells (HaCaT-EX) pretreated with high glucose.

Acute ethanol exposure stimulates microvesicle particle generation in keratinocytes.

Ethanol has been demonstrated to exert profound effects upon cells and tissues via multiple mechanisms. One recently appreciated means by which cells can communicate with other cells is via the production and release of extracellular vesicles. Though smaller exosomes have been demonstrated to be released in response to ethanol exposure, the ability of ethanol to modulate the generation and release of larger microvesicle particles (MVP) is lesser studied.

Methylation of the serotonin transporter gene moderates the depressive subjective effect of cocaine.

Genetic variation in the serotonin transporter (SLC6A4) has been shown to moderate the acute subjective effects of cocaine. Methylation of the SLC6A4 gene is associated with decreased transcription of the serotonin transporter, leading to increased serotonin in the synapse. In this study, methylation of the SLC6A4 gene was investigated in the moderation of the subjective effects of cocaine.

Assessment of Protection Offered By the NRF2 Pathway Against Hyperoxia-Induced Acute Lung Injury in NRF2 Knockout Rats.

Nuclear factor erythroid 2-related factor (Nrf2) is a redox-sensitive transcription factor that responds to oxidative stress by activating expressions of key antioxidant and cytoprotective enzymes via the Nrf2-antioxidant response element (ARE) signaling pathway. Our objective was to characterize hyperoxia-induced acute lung injury (HALI) in Nrf2 knock-out (KO) rats to elucidate the role of this pathway in HALI. Adult Nrf2 wildtype (WT), and KO rats were exposed to room air (normoxia) or >95% O2 (hyperoxia) for 48 h, after which selected injury and functional endpoints were measured in vivo and ex vivo.
