Ecosystem service indicators on military-managed drylands in the Western United States.

Lands devoted to military use are globally important for the production of ecosystem services and for the conservation of biodiversity. The United States has one of the largest military land estates in the world, and most of these areas occur in water-limited landscapes. Despite many of these areas receiving intense or sustained disturbance from military training activities, the structure and function of ecosystems contained within their boundaries continue to provide critical benefits to people across spatial scales.

A New Analytical Method for Quantifying Acid-End-Cap PLGA in Sub-Milligram Quantities.

Characterization of PLGA polymers used in FDA-approved drug products is critical for quality control and qualitative/quantitative (Q1/Q2) evaluation of potential generic formulations. Various techniques have been developed and used to characterize the molecular properties of PLGA polymers, such as molecular weight, molecular composition, and molecular structure. Commonly used techniques include gel permeation chromatography (GPC), nuclear magnetic resonance (NMR), semisolvent methods, and GPC-based intrinsic viscosity measurement.

Sublingual Sufentanil Tablet for Analgesia in Emergency Medical Services and Search and Rescue Agencies.

Objectives: Pain management in the potentially austere search and rescue (SAR) and emergency medical services (EMS) environments can be challenging. Intravenous (IV) and intramuscular (IM) routes of administration may be less practical. This study assesses the efficacy and safety of the sublingual sufentanil tablet (SST) in prehospital settings and hypothesizes that its use will reduce pain while maintaining a reasonable safety profile.

Correlation between polymer properties, extrusion process parameters and permeability of etonogestrel in ethylene vinyl acetate (EVA) films.

Ethylene vinyl acetate (EVA) copolymers have been extensively used in controlled drug delivery systems due to its good biocompatibility and tunable applicability based on simple variations in vinyl acetate (VA) content. We investigated impacts of polymer properties and extrusion process parameters of EVA on permeability of etonogestrel in EVA films. Among all factors studied, the VA content was the most dominant factor that controls drug permeability by affecting crystallinity of EVA.

Safety and immunogenicity of the Ad26/protein preF RSV vaccine in adults aged 18 to 59 years with and without at-risk comorbidities for severe respiratory syncytial virus disease: A phase 3, randomized, controlled, immunobridging trial.

Background: Respiratory syncytial virus (RSV) causes a significant disease burden in adults with chronic comorbidities. Rates of severe RSV disease and death are as high, or higher in younger adults with risk factors than in healthy older adults in whom RSV vaccination is recommended. We conducted an immunobridging study using the Ad26/protein RSV preF vaccine, which previously demonstrated efficacy in adults aged ≥65 years to support extrapolation of efficacy demonstrated in an older population to younger adult populations at high risk of severe RSV disease.

Hydrogen tunneling with an atypically small KIE measured in the mediated decomposition of the Co(CHCOOH) complex.

Quantum mechanical tunneling (QMT) is a well-documented phenomenon in the C-H bond activation mechanism and is commonly identified by large KIE values. Herein we present surprising findings in the kinetic study of hydrogen tunneling in the Co mediated decomposition of acetic acid and its perdeuterated isotopologue, conducted with the energy resolved single photon initiated dissociative rearrangement reaction (SPIDRR) technique. Following laser activation, the reaction proceeds along parallel product channels Co(CHO) + CO and Co(CHO) + HO.

Direct and Legacy Effects of Varying Cool-Season Precipitation Totals on Ecosystem Carbon Flux in a Semi-Arid Mixed Grassland.

In the semi-arid grasslands of the southwest United States, annual precipitation is divided between warm-season (July-September) convective precipitation and cool-season (December-March) frontal storms. While evidence suggests shifts in precipitation seasonal distribution, there is a poor understanding of the ecosystem carbon flux responses to cool-season precipitation and the potential legacy effects on subsequent warm-season carbon fluxes. Results from a two-year experiment with three cool-season precipitation treatments (dry, received 5th percentile cool-season total precipitation; normal, 50th; wet, 95th) and constant warm-season precipitation illustrate the direct and legacy effects on carbon fluxes, but in opposing ways.

Racial Attitudes and Perceptions of Government Response during the COVID-19 Pandemic: Implications for Public Health Strategies.

Background: This study explored whether opinions about the government's role in addressing the COVID-19 pandemic vary based on demographic characteristics and racial beliefs. We hypothesized that opinions about the United States (U.S.

mushroom anaphylaxis: A case report and review of the literature.

Objective: Our aim was to describe a case of anaphylaxis in an older nonatopic patient following ingestion of and undertake a review of the literature.

Cervical squamous cell carcinoma outcomes across continents: A retrospective study.

Objective: To assess the influence of geographies and race on the survival outcomes in patients diagnosed with cervical squamous cell carcinoma (CSCC) across three continents.

Methods: This multicontinental retrospective study was conducted in 8 hospitals across Asia, Europe, and North America (NA). Clinicopathologic data of 595 patients with presumed early stages of CSCC, treated surgically, with curative intent was collected.

Ion Correlations Decrease Particle Aggregation Rate by Increasing Hydration Forces at Interfaces.

The connection between solution structure, particle forces, and emergent phenomena at solid-liquid interfaces remains ambiguous. In this case study on boehmite aggregation, we established a connection between interfacial solution structure, emerging hydration forces between two approaching particles, and the resulting structure and kinetics of particle aggregation. In contrast to expectations from continuum-based theories, we observed a nonmonotonic dependence of the aggregation rate on the concentration of sodium chloride, nitrate, or nitrite, decreasing by 15-fold in 4 molal compared to 1 molal solutions.

Whole Nervous System Expression of Glutamate Receptors Reveals Distinct Receptor Roles in Sensorimotor Circuits.

The goal of connectomics is to reveal the links between neural circuits and behavior. Larvae of the primitive chordate are well-suited to make contributions in this area. In addition to having a described connectome, larvae have a range of readily quantified behaviors.

Manufacture, characterization, and elucidation of drug release mechanisms of etonogestrel implants based on ethylene vinyl acetate.

In this work, etonogestrel implants were manufactured using coextrusion. The purpose of the study was to correlate changes in microstructure and transport properties that occurred in etonogestrel implants to drug release mechanisms. The implants consisted of an EVA 28 (28 % vinyl acetate) core containing dispersed and dissolved etonogestrel, and an EVA 15 (15 % vinyl acetate) skin.

The Australasian Registry for Severe Cutaneous Adverse Reactions (AUS-SCAR) - Providing a roadmap for closing the diagnostic, patient, and healthcare gaps for a group of rare drug eruptions.

Background: Severe cutaneous adverse reactions (SCAR) are a group of delayed presumed T-cell mediated hypersensitivities associated with significant morbidity and mortality. Despite their shared global healthcare burden and impact, the clinical phenotypes, genomic predisposition, drug causality, and treatment outcomes may vary. We describe the establishment and results from the first Australasian registry for SCAR (AUS-SCAR), that via a collaborative network advances strategies for the prevention, diagnosis and treatment of SCAR.

A growth-differentiation factor 15 receptor agonist in randomized placebo-controlled trials in healthy or obese persons.

Background: Growth Differentiation Factor 15 (GDF15), a divergent member of the TGF-β superfamily, signals via the hindbrain glial-derived neurotrophic factor receptor alpha-like and rearranged during transfection receptor co-receptor (GFRAL-RET) complex. In nonclinical species, GDF15 is a potent anorexigen leading to substantial weight loss. MBL949 is a half-life extended recombinant human GDF15 dimer.

Negative Lifestyle Factors Specific to Aging Persons Living with HIV and Multimorbidity.

The primary goal of medical care during the pre-antiretroviral therapy (ART) era was to keep persons living with human immunodeficiency virus (HIV) alive, whereas since the advent of ART, the treatment objective has shifted to decreasing viral loads and infectiousness while increasing CD4+ T-cell counts and longevity. The health crisis, however, is in preventing and managing multimorbidity (ie, type 2 diabetes), which develops at a more accelerated or accentuated pace among aging persons living with HIV. Relative to the general population and age-matched uninfected adults, it may be more difficult for aging HIV-positive persons who also suffer from multimorbidity to improve negative lifestyle factors to the extent that their behaviors could support the prevention and management of diseases.
