Apigenin exhibits memory enhancing activity through the restoration of oxido-endocrine balance and upregulation of BDNF/ERK/CREB signalling pathways in stressed mice.

Stress is linked to oxidative imbalance, neuroendocrine system malfunction, and cognitive dysfunction. It is a recognized cause of neuropsychiatric diseases. Natural flavonoid apigenin (API) has neuroprotective and antidepressant properties, but little is known about its potential in restoring memory function under stress-related circumstances.

Don't Sleep on Vitamin D: Vitamin D is Associated with Sleep Variability in Apparently Healthy Adults.

Vitamin D is associated with sleep quality and duration, but it's unclear whether vitamin D status influences sleep variability. Therefore, we sought to determine whether vitamin D status was associated with sleep variability in healthy adults. We assessed objective sleep, including timing and duration standard deviation () using the Philips Actiwatch Spectrum and subjective sleep quality using the Pittsburgh Sleep Quality Index (PSQI) in 130 adults.

Policy Recommendations to Support Equitable Access to Long-Acting Injectables for Human Immunodeficiency Virus Prevention and Treatment: A Policy Paper of the Infectious Diseases Society of America and the HIV Medicine Association.

Long-acting injectables (LAIs) for HIV prevention and treatment could dramatically improve health outcomes and health equity for people with HIV and those who could benefit from pre-exposure prophylaxis. Despite widespread acceptability and demand by providers and potential users of LAIs, implementation has been extremely limited since the introduction of cabotegravir/rilpivirine, the first LAI for HIV treatment, in January 2021, and long-acting cabotegravir, the first LAI for HIV prevention, in December 2021. We report results of a provider survey, conducted by the HIV Medicine Association, which identified LAI implementation barriers related to health insurance processes, staffing and administrative support, drug costs and acquisition, and access for individuals who are uninsured.

Positive feedback regulation between RpoS and BosR in the Lyme disease pathogen.

In , the causative agent of Lyme disease, differential gene expression is primarily governed by the alternative sigma factor RpoS (σ). Understanding the regulation of RpoS is crucial for elucidating how is maintained throughout its enzootic cycle. Our recent studies have shown that the homolog of Fur/PerR repressor/activator BosR functions as an RNA-binding protein that controls the mRNA stability.

Temporal Genomic Analysis of Homogeneous Tumor Models Reveals Key Regulators of Immune Evasion in Melanoma.

In this study, we find that Mif expression is associated with tumor growth and aggressiveness, specifically in tumors with low heterogeneity. These findings could facilitate the development of new strategies to treat patients with homogeneous, high MIF-expressing tumors that are unresponsive to immune checkpoint therapy.

Skeletal organoids.

The skeletal system, composed of bones, muscles, joints, ligaments, and tendons, serves as the foundation for maintaining human posture, mobility, and overall biomechanical functionality. However, with ageing, chronic overuse, and acute injuries, conditions such as osteoarthritis, intervertebral disc degeneration, muscle atrophy, and ligament or tendon tears have become increasingly prevalent and pose serious clinical challenges. These disorders not only result in pain, functional loss, and a marked reduction in patients' quality of life but also impose substantial social and economic burdens.

Cellular senescence induced by down-regulation of correlates with exon skipping of mitochondrial-related gene .

As the most prevalent type of alternative splicing in animal cells, exon skipping plays an important role in expanding the diversity of transcriptome and proteome, thereby participating in the regulation of diverse physiological and pathological processes such as development, aging, and cancer. Cellular senescence serving as an anti-cancer mechanism could also contribute to individual aging. Although the dynamic changes of exon skipping during cellular senescence were revealed, its biological consequence and upstream regulator remain poorly understood.

Furin-Mediated Modification Is Required for Epithelial Sodium Channel-Activating Activity of Soluble (Pro)Renin Receptor in Cultured Collecting Duct Cells.

(Pro)renin receptor (PRR) contains overlapping cleavage site for site-1 protease (S1P) and furin for generation of soluble PRR (sPRR). Although S1P-mediated cleavage mediates the release of sPRR, the functional implication of furin-mediated cleavage is unclear. Here we tested whether furin-mediated cleavage was required for the activity of sPRR in activating ENaC in cultured M-1 cells.

Tau oligomers impair memory and synaptic plasticity through the cellular prion protein.

Deposition of abnormally phosphorylated tau aggregates is a central event leading to neuronal dysfunction and death in Alzheimer's disease (AD) and other tauopathies. Among tau aggregates, oligomers (TauOs) are considered the most toxic. AD brains show significant increase in TauOs compared to healthy controls, their concentration correlating with the severity of cognitive deficits and disease progression.

The mechanisms underlying these relationships are not well understood and may be mediated by different midlife risk factors. We examined the mediating role of various factors on the relationship between the number of children and dementia risk.

Protocol for visual-acoustic intervention with service delivery in-person and via telepractice (VISIT) non-inferiority trial for residual speech sound disorder.

Background: Residual speech sound disorder (RSSD) is a high-prevalence condition that negatively impacts social and academic participation. Telepractice service delivery has the potential to expand access to technology-enhanced intervention methods that can help remediate RSSD, but it is not known whether remote service delivery is associated with a reduction in the efficacy of these methods. This project will systematically measure the outcomes of visual-acoustic biofeedback intervention when delivered in-person or online.

ULACNet-301, OPTIMO protocol: optimizing HPV vaccination regimen for cancer prevention in children and adolescents living with HIV.

Background: Persistent infection with human papillomavirus (HPV) is associated with most cervical and anal cancer cases and a large fraction of other anogenital and oropharyngeal cancers. The prophylactic HPV vaccines are known to prevent HPV infections and HPV-associated disease, although there is evidence of reduced response to the HPV vaccination among individuals living with HIV. Prior studies among individuals without HIV suggest that a single HPV vaccine dose induces humoral immune responses that, while lower than those induced by two or three doses, still confer protection against HPV infection.
