Despite a plethora of research examining campus dating and sexual violence (DSV) risk and protective factors, little of this research has been conducted at non-traditional institutions such as minority-serving institutions (MSIs), community colleges, or non-predominantly white institutions. A review of research on statistically significant protective and risk factors for campus perpetration or victimization at non-traditional institutions resulted in 12 articles. The inclusion criteria for the study were that the article was in English, in a peer-reviewed journal, and published between 2010 and 2021.

Neurotropic viruses are a major public health concern as they can cause encephalitis and other severe brain diseases. Many of these viruses, including flaviviruses, herpesviruses, rhabdoviruses and alphaviruses enter the brain through the olfactory neuroepithelium (ONE) in the olfactory bulbs (OB). Due to the low percentage of encephalitis that occurs following these infections, it's thought that the OBs have specialized innate immune responses to eliminate viruses.

Background: Current research on the transmission of trauma and eating disorders across generations is limited. However, quantitative studies suggest that the influence of parents' and grandparents' eating disorders and their prior exposure to trauma are associated with the development of eating disorders in future generations. Qualitative research exploring personal accounts of the impact of transgenerational trauma on the development of eating disorders has been largely unexplored.

Enantiornithes are the most successful early-diverging avian clade, their fossils revealing important information regarding the structure of Cretaceous avifaunas and the parallel refinement of flight alongside the ornithuromorph lineage that includes modern birds. The most diverse recognized family of Early Cretaceous enantiornithines is the Bohaiornithidae, known from the Jehol Biota in northeastern China. Members of this clade enhance our understanding of intraclade morphological diversity and elucidate the independent evolution of this unique lineage.

Neuroendocrine carcinomas are rare and aggressive malignancies, often diagnosed at advanced stages, leading to poor prognosis. Platinum-based chemotherapy is the standard first-line treatment for advanced neuroendocrine carcinomas; however after achieving response no consensus exists on maintenance therapies and the results are inconsistent. This review examines the role of maintenance therapy following response to first-line chemotherapy in gastroenteropancreatic neuroendocrine carcinomas.

Climate change has emerged as a key threat to biodiversity, leading to broad-scale shifts in distributions of marine and terrestrial species as they attempt to track thermally suitable habitat. By contrast, our understanding of climate responses of freshwater species is relatively undeveloped, limiting our knowledge of whether projected warming will lead to freshwater biodiversity loss. Here, we linked a multicontinental database of riverine fish population abundance time series collected from 1958 to 2019 to temperature data from the same period.

Article Synopsis
  • The study explored how a high-fiber/low-fat agrarian diet (AD) affects inflammation and metabolic health in HIV-positive men who have sex with men (MSM).
  • Participants included 36 HIV-positive MSM, with results showing the AD reduced harmful cholesterol and improved immune function, especially in those with specific gut microbiome types.
  • The findings suggest that customizing dietary interventions based on individual microbiomes could enhance metabolic health for HIV-positive MSM.

Introduction: South Asian adults are at high risk for atherosclerotic cardiovascular disease, for which coronary artery calcification is an early predictor. Adherence to the Dietary Approaches to Stop Hypertension diet is a modifiable risk factor that may mitigate the progression of coronary artery calcification and atherosclerotic cardiovascular disease.

Methods: Using data from the Mediators of Atherosclerosis in South Asians Living in America cohort, the authors calculated a Dietary Approaches to Stop Hypertension dietary score (categorized as low, moderate, and high) to examine the associations of Dietary Approaches to Stop Hypertension diet adherence with coronary artery calcification after a 5-year follow up.

Article Synopsis
  • Venovenous extracorporeal membrane oxygenation (VV ECMO) is used for severe acute respiratory distress syndrome and has recently been applied to trauma patients with lung injuries; the study compares survival outcomes of these two groups.
  • The study analyzed data from 516 patients (438 nontrauma and 78 trauma) over eight years, revealing that trauma patients generally had poorer health indicators but similar survival rates compared to nontrauma patients.
  • The results showed that trauma patients experienced shorter ECMO durations, more severe conditions before treatment, but managed a comparable survival rate to those without trauma, suggesting effectiveness in trauma care with VV ECMO.

Article Synopsis
  • Coronaviruses can originate from animals and cause serious illnesses in both humans and animals, with a key protein called Mac1 playing a role in viral replication and interferon inhibition.
  • Researchers discovered a compound, MCD-628, that inhibits Mac1 but found its effectiveness was limited due to poor permeability.
  • By creating more hydrophobic derivatives, they identified four compounds that successfully inhibited Mac1 and reduced replication of coronaviruses, confirming their specificity through drug-resistance mutations, but this resistance came at a cost to the virus's overall fitness.

The Easter mantle plume has produced one of the longest hotspot tracks in the Pacific Ocean. While previous studies have focused on the eastern side extending across the Nazca Plate, we use Ar/Ar isotopic and geochemical data to investigate the less explored western side around the Easter Microplate. We propose a dynamic model in which a deeper (600 km-depth), less buoyant mantle exerts a westward force on the East Pacific Rise (EPR), while a more buoyant plume region drives Easter hotspot volcanism and a localised acceleration in seafloor spreading.

Article Synopsis
  • The study examines sleep behaviors in individuals with Cornelia de Lange syndrome (CdLS) caused by variants in two genes, NIPBL and SMC1A, which are linked to developmental delays.
  • Caregivers of 31 individuals provided data showing that those with NIPBL variants exhibited more behavior regulation difficulties and repetitive behaviors compared to those with SMC1A variants.
  • The research highlights a strong connection between sleep disturbances and behavior regulation challenges, particularly in the NIPBL group, suggesting that sleep interventions may help manage behavioral issues differently depending on the genetic variant.
