Trifluoroacetic Acid Induced a Cyclophilin D-Dependent Cognitive Impairment in Mice.

Studies have linked inhalation anesthesia and surgery to increased cognitive impairment, particularly in the elderly. Our previous research showed that isoflurane, but not desflurane, affected cognitive function in mice by modulating cyclophilin D (CypD), a key regulator of the mitochondrial permeability transition pore (mPTP) and mitochondrial function. Both anesthetics metabolize into trifluoroacetic acid (TFA), which is associated with cognitive deficits.

Leukemogenic Kras mutation reprograms multipotent progenitors to facilitate its spread through the hematopoietic system.

Leukemia-driving mutations are thought to arise in hematopoietic stem cells (HSC), yet the natural history of their spread is poorly understood. We genetically induced mutations within endogenous murine HSC and traced them in unmanipulated animals. In contrast to mutations associated with clonal hematopoiesis (such as Tet2 deletion), the leukemogenic KrasG12D mutation dramatically accelerated HSC contribution to all hematopoietic lineages.

Volumetric, Microfluidic Plasmonic RT-PCR.

Decentralized molecular detection of pathogens remains an important goal for public health. Although polymerase chain reaction (PCR) remains the gold-standard molecular detection method, thermocycling using Peltier heaters presents challenges in decentralized settings. Recent work has demonstrated plasmonic PCR, where nanomaterials on a surface or nanoparticles in solution heat upon stimulation by light, as a promising method for rapid thermocycling.

A Spatial Epidemiologic Analysis of Opioid Use Disorder Treatment in New York State.

Background: Opioid agonist treatments (OAT; methadone and buprenorphine) for opioid use disorder (OUD) reduce overdose death by more than 50%. Low population-level rates of OAT are missed opportunities to reduce OUD-related mortality.

Objective: We examined county-level OAT utilization patterns to guide state-level and county-level initiatives to improve equitable access and utilization in New York State (NYS).

Abrasion Effect on Heating Performance of Carbon Nanotube/Epoxy Composites.

The effects of abrasion on the heating performance of carbon nanotube (CNT)/epoxy composites were investigated in terms of Joule's heat, convective heat, and radiative heat under moderate-to-severe and localized abrasive conditions. While the overall heating behavior was characterized by the heating rate and the curvature of the transient response, a numerical solution of the heat equation was used to quantify convective and radiative heat transfers, incorporating the specific heat of each component, the convective heat transfer coefficient, and the Biot number. CNT reinforcement significantly improved wear resistance at a CNT concentration of 0.

Interleukin 24 Promotes Mitochondrial Dysfunction, Glucose Regulation, and Apoptosis by Inactivating Glycogen Synthase Kinase 3 Beta in Human Prostate Cancer Cells.

Interleukin 24 (IL-24) is a tumor-suppressing protein currently in clinical trials. We previously demonstrated that IL-24 leads to apoptosis in cancer cells through protein kinase A (PKA) activation in human breast cancer cells. To better understand the mechanism by which IL-24 induces apoptosis, we analyzed the role of glycogen synthase kinase-3 beta (GSK3β), a highly conserved serine/threonine kinase in cancer cells and a downstream target of PKA.

Evolution of silicate coordination in architected amorphous and crystalline magnesium silicates during carbon mineralization.

Advancing durable solutions for carbon storage and removal at the gigaton scale to produce solid carbonates carbon mineralization requires harnessing earth abundant magnesium silicate resources. Calibrated insights linking the structural and morphological features of earth abundant amorphous and crystalline magnesium silicate phases to their reactivity are essential for scalable deployment but remain underdeveloped. To resolve the influence of silica coordination and mass transfer on carbon mineralization behavior, magnesium silicates bearing amorphous and crystalline phases (AC Mg-silicate) are synthesized.

Impact of commercial RNA extraction methods on the recovery of human RNA sequence data from archival fixed tissues.

Archival fixed tissues hold key insights into the evolutionary history of RNA viruses and the associated host immune response, yet access to the RNA sequence data is limited by a lack of robust methods for RNA extraction and sequence retrieval from these tissue types. Here we compared three commercial RNA extraction techniques (bead, column, and phase-based) on five fixed human brain tissues done in triplicate, that have been stored for up to 43 years. We found that for this sample set, bead-based extractions captured longer molecules and yielded a greater proportion of unique reads when aligned to the human genome, than did column and phase-based extraction methods.

Background: Today, computer games have become one of the most popular forms of entertainment, especially among teenagers. While games may have various benefits, video games are shown to have different consequences for players, especially those who are younger, and can be highly addictive. The present research investigated the effect of computer game addiction on anxiety and depression in adolescents with the mediating role of social support.

Do child and household regulation moderate the bidirectional relation between harsh parenting and externalizing problems in the transition to adolescence?

The present study examined several distinct indicators of regulation (i.e., task-based executive function, surveyed child effortful control, and surveyed household chaos) as moderators of longitudinal bidirectional links between developmental changes in harsh parenting (HP) and child externalizing behaviors (EXT) from age 9 to 14 years.

Medicaid Home and Community Based Services Spending and Nursing Home Use by Individuals Under the Age of 44.

Prior studies of the role of state spending on home and community-based services (HCBS) in nursing home use focused on adults over the age of 65. However, medically complex children and adults under 50 years old represent a small (about 5%) but highly vulnerable subset of nursing home patients. We measured the impact of HCBS spending on short-term and long-term nursing home stays by children and adults under 44 years old and compared the impact between Non-Hispanic White (NHW) individuals and Black, Indigenous, and People of Color (BIPOC).

Battery-free head orientation measurement using passive RFID tags.

Real-time measurement of head rotation, a primary human body movement, offers potential advantages in rehabilitating head or neck motor disorders, promoting seamless human-robot interaction, and tracking the lateral glance of children with autism spectrum disorder for effective intervention. However, existing options such as cameras capturing the entire face or skin-attached sensors have limitations concerning privacy, safety, and/or usability. This research introduces a novel method that employs a battery-free RFID tag-based wearable sensor for monitoring head orientation, as a substitute for the existing options like camera.

Novel device therapies in heart failure: focus on patient selection.

The increasing prevalence of heart failure (HF) has led to advancements in therapeutic strategies, including the development of new pharmacological treatments and the expansion of guideline recommendations across the spectrum of left ventricular ejection fractions. Despite these advancements, the full benefits of guideline-directed medical therapy (GDMT) are often limited by various barriers that result in incomplete implementation or suboptimal responses. For patients who cannot tolerate or only partially respond to GDMT, therapeutic options remain limited.

Consensus statement on the prevention, diagnosis, and management of infection following transcutaneous osseointegration for patients with limb loss: current state-of-the-art and proposed future studies.

The diagnosis, risk factors, treatment algorithms, and long-term sequelae of superficial and deep, implant-related infections in transdermal, bone-anchored osseointegration are not well-defined. In contrast to the robust experience diagnosing and managing periprosthetic joint infections in total joint arthroplasty, osseointegration surgery has only recently been adopted at a small number of osseointegration centers in the United States, contributing to the lack of long-term outcomes. Through the pooled experience from these osseointegration centers, we present a consensus statement on the perioperative management, incidence, treatment, and diagnostic workup for infectious complications following transdermal, bone-anchored osseointegration.
