Association between pituitary adenoma consistency, resection techniques, and patient outcomes: a single-institution experience.

Objective: The present study aimed to investigate the association between pituitary adenoma (PA) consistency and other measurable tumor characteristics, extent of resection (EOR), postoperative complications, and outcomes.

Methods: In total, 507 PA resections were intraoperatively assigned a consistency grade from 1 (cystic/hemorrhagic tumors) to 5 (calcified tumors) based on intraoperative tumor characteristics. Tumor consistency was analyzed in tertiles (grades 1 and 2, grade 3, and grades 4 and 5) to determine associations with tumor characteristics, EOR, recurrence, postoperative outcomes, and complications.

Intervalence Charge Transfer in an Osmium(IV) Tetra(ferrocenylaryl) Complex.

The functional properties of tetraaryl compounds, M(aryl) (M = transition metal or group 14 element), are dictated not only by their common tetrahedral geometry but also by their central atom. The identity of this atom may serve to modulate the reactivity, electrochemical, magnetic, and optical behavior of the molecular species, or of extended materials built from appropriate tetraaryl building blocks, but this has not yet been systematically evaluated. Toward this goal, here we probe the influence of Os(IV), C, and Si central atoms on the spectroelectrochemical properties of a series of redox-active tetra(ferrocenylaryl) complexes.

Cost-effectiveness of leveraging existing HIV primary health systems and community health workers for hypertension screening and treatment in Africa: An individual-based modeling study.

Background: Cardiovascular disease (CVD) morbidity and mortality is increasing in Africa, largely due to undiagnosed and untreated hypertension. Approaches that leverage existing primary health systems could improve hypertension treatment and reduce CVD, but cost-effectiveness is unknown. We evaluated the cost-effectiveness of population-level hypertension screening and implementation of chronic care clinics across eastern, southern, central, and western Africa.

SOX9 is a crucial transcriptional regulator of cartilage development and homeostasis. Dysregulation of is associated with a wide spectrum of skeletal disorders, including campomelic dysplasia, acampomelic campomelic dysplasia, and scoliosis. Yet how variants contribute to the spectrum of axial skeletal disorders is not well understood.

Sex-specific activation of platelet purinergic signaling is key in local cytokine release and phagocytosis in the peritoneal cavity in intra-abdominal sepsis.

Intra-abdominal sepsis is a life-threatening complex syndrome caused by microbes in the gut microbiota invading the peritoneal cavity. It is one of the major complications of intra-abdominal surgery. To date, only supportive therapies are available.

City-Level Sugar-Sweetened Beverage Taxes and Changes in Adult Body Mass Index.

Importance: Sugar-sweetened beverage (SSB) excise taxes are popular policy interventions aimed at decreasing SSB purchasing and consumption to improve cardiometabolic health and generate revenue for public health initiatives. There is limited evidence that these taxes in the US are associated with weight-related outcomes in adults, a primary contributor to cardiometabolic health.

Objective: To determine the association between SSB excise taxes and adult body mass index (BMI) and proportion of adults with overweight or obesity among California cities and assess whether associations vary by demographic characteristics.

Mcl-1 is a Gatekeeper Molecule to Regulate the Crosstalk Between Ferroptotic Agent-Induced ER Stress and TRAIL-Induced Apoptosis.

We previously reported that ferroptosis interplays with apoptosis through the integration of two independent pathways: the endoplasmic reticulum (ER) stress signaling pathway and the mitochondria-dependent apoptotic signaling pathway. In this study, we investigated a potential gatekeeper molecule, Mcl-1, between the two signal transduction pathways. Morphology studies and cell death analyses confirmed that a combination treatment of ferroptotic agent erastin (ERA) and apoptotic agent TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) synergistically enhances TRAIL-induced apoptosis in human pancreatic adenocarcinoma BxPC3 and human colorectal carcinoma HCT116 cells.

Between- and Within-Cluster Spearman Rank Correlations.

Species and Their Associations with Chaparral and Oak Woodland Vegetation in Southern California.

Evidence of unintended introductions of species into native habitats has become increasingly prevalent in California. If not managed adequately, species can become devastating agricultural and forest plant pathogens. Additionally, California's natural areas, characterized by a Mediterranean climate and dominated by chaparral (evergreen, drought-tolerant shrubs) and oak woodlands, lack sufficient baseline knowledge on biology and ecology, hindering effective management efforts.

Regional Gene Therapy Compared to Recombinant BMP-2 for the Treatment of Critical-Size Bone Defects: An In Vivo Single-Cell RNA-Sequencing Study.

regional gene therapy is a promising tissue-engineering strategy for bone regeneration: osteogenic mesenchymal stem cells (MSCs) can be genetically modified to express an osteoinductive stimulus (e.g., bone morphogenetic protein-2), seeded onto an osteoconductive scaffold, and then implanted into a bone defect to exert a therapeutic effect.

Intimate partnerships during COVID-19 for immigrant women in New York City.

Objective: This study examines perceptions of changes in intimate relationships among partnered, immigrant women in New York City during the first year of the COVID-19 pandemic. We pay close attention to how structural oppression, particularly related to undocumented immigration status, shaped women's experiences with their intimate partners during a period of social upheaval.

Background: COVID-19 has exacerbated many existing structural inequities and subsequent stressors that have been shown to have an adverse effect on intimate relationships, including increased economic instability and mental health distress.

Atacama Large Aperture Submillimeter Telescope (AtLAST) science: Probing the transient and time-variable sky.

The study of transient and variable events, including novae, active galactic nuclei, and black hole binaries, has historically been a fruitful path for elucidating the evolutionary mechanisms of our universe. The study of such events in the millimeter and submillimeter is, however, still in its infancy. Submillimeter observations probe a variety of materials, such as optically thick dust, which are hard to study in other wavelengths.

Improving the solubility of pseudo-hydrophobic chemicals through co-crystal formulation.

Natural products are ligands and in vitro inhibitors of Alzheimer's disease (AD) tau. Dihydromyricetin (DHM) bears chemical similarity to known natural product tau inhibitors. Despite having signature polyphenolic character, DHM is ostensibly hydrophobic owing to intermolecular hydrogen bonds that shield hydrophilic phenols.
