Understanding the impacts of drought on peanuts L.): exploring physio-genetic mechanisms to develop drought-resilient peanut cultivars.

Peanut is a vital source of protein, particularly in the tropical regions of Asian and African countries. About three-quarters of peanut production occurs worldwide in arid and semi-arid regions, making drought an important concern in peanut production. In the US about two-thirds of peanuts are grown in non-irrigated lands, where drought accounts for 50 million USD loss each year.

Muscarinic receptor agonists and positive allosteric modulators in animal models of psychosis: protocol for a systematic review and meta-analysis.

Background: Muscarinic receptor agonism and positive allosteric modulation is a promising mechanism of action for treating psychosis, not present in most D2R-blocking antipsychotics. Xanomeline, an M1/M4-preferring agonist, has shown efficacy in late-stage clinical trials, with more compounds being investigated. Therefore, we aim to synthesize evidence on the preclinical efficacy of muscarinic receptor agonists and positive allosteric modulators in animal models of psychosis to provide unique insights and evidence-based information to guide drug development.

Optimizing Enantiomeric Resolution of Chiral Triazoles in Supercritical Fluid Chromatography.

Chirality plays a crucial role in the pharmacological activity of triazoles, a key scaffold in antifungal agents and various therapeutic applications. This study focuses on optimizing the enantiomeric resolution of chiral triazoles using supercritical fluid chromatography (SFC) and 10 different columns, either immobilized or coated, chlorinated or nonchlorinated, cellulose or amylose-based chiral stationary phases (CSPs). Four novel triazoles and two marketed ones (tebuconazole and hexaconazole) were separated to determine optimal resolution conditions.

Traditional manual counting methods are labor intensive and prone to human error, highlighting the need for automated systems. This study presents a stand-alone automated mosquito egg counting system using a Raspberry Pi computer, high-quality camera, light-emitting diode ring light source, and a Python script leveraging the Open Source Computer Vision library.

Impact of fluconazole on outcomes of patients with primary pulmonary coccidioidomycosis: a commercial health insurance claims-based, propensity score matched analysis.

Background: Patients with pulmonary coccidioidomycosis often experience prolonged symptoms lasting weeks to months. Limited data exist regarding whether fluconazole prevents development of disseminated disease or shortens symptom duration. We describe factors associated with fluconazole receipt and assess its effect on outcomes among patients with pulmonary coccidioidomycosis.

Atg5 deficiency in basophils improves metabolism in lupus mice by regulating gut microbiota dysbiosis.

Autophagic activation in immune cells, gut microbiota dysbiosis, and metabolic abnormalities have been reported separately as characteristics of systemic lupus erythematosus (SLE). Elucidating the crosstalk among the immune system, commensal microbiota, and metabolites is crucial to understanding the pathogenesis of autoimmune diseases. Emerging evidence shows that basophil activation plays a critical role in the pathogenesis of SLE; however, the underlying mechanisms remain largely unknown.

Analysis methods for covariate-constrained cluster randomized trials with time-to-event outcomes.

Background: Cluster randomized trials, which often enroll a small number of clusters, can benefit from constrained randomization, selecting a final randomization scheme from a set of known, balanced randomizations. Previous literature has addressed the suitability of adjusting the analysis for the covariates that were balanced in the design phase when the outcome is continuous or binary. Here we extended this work to time-to-event outcomes by comparing two model-based tests and a newly derived permutation test.

Thermal variation influences the transcriptome of the major malaria vector Anopheles stephensi.

The distribution and abundance of ectothermic mosquitoes are strongly affected by temperature, but mechanisms remain unexplored. We describe the effect of temperature on the transcriptome of Anopheles stephensi, an invasive vector of human malaria. Adult females were maintained across a range of mean temperatures (20 °C, 24 °C and 28 °C), with daily fluctuations of +5 °C and -4 °C at each mean temperature.

Structure and mechanism of biosynthesis of Streptococcus mutans cell wall polysaccharide.

Streptococcus mutans, the causative agent of human dental caries, expresses a cell wall attached Serotype c-specific Carbohydrate (SCC) that is critical for cell viability. SCC consists of a polyrhamnose backbone of →3)α-Rha(1 → 2)α-Rha(1→ repeats with glucose (Glc) side-chains and glycerol phosphate (GroP) decorations. This study reveals that SCC has one predominant and two more minor Glc modifications.

Metabolic interactions underpinning high methane fluxes across terrestrial freshwater wetlands.

Current estimates of wetland contributions to the global methane budget carry high uncertainty, particularly in accurately predicting emissions from high methane-emitting wetlands. Microorganisms drive methane cycling, but little is known about their conservation across wetlands. To address this, we integrate 16S rRNA amplicon datasets, metagenomes, metatranscriptomes, and annual methane flux data across 9 wetlands, creating the Multi-Omics for Understanding Climate Change (MUCC) v2.

Paediatricians' Perspectives Surrounding Identification and Management of Early Childhood Disorders in the United States.

Background: Since 2001, the American Academy of Pediatrics has released and twice revised guidelines tasking paediatricians with screening children for developmental disorders, but diagnoses are often delayed. Paediatricians in the United States are also responsible for referring patients with identified concerns for services and for managing their long-term care.

Objectives: This review aims to chronologically synthesize available literature about paediatricians' perspectives surrounding their roles in identifying and managing early childhood disorders and to identify how future interventions can best address these perspectives.

The PRO-AGE Tool and Its Association With Post Discharge Outcomes in Older Adults Admitted From the Emergency Department.

Methods: Multicenter cohort study of infants with birthweight 401 to 1000 g or gestational age 22 to 28 weeks. LOS was defined as a bacterial or fungal pathogen isolated from blood or cerebrospinal fluid culture obtained after 72 hours of age.

Increases in mean arterial blood pressure during electrical stimulation are unreliable indicators of anesthetic depth measured with electroencephalogram in dogs anesthetized with sevoflurane.

Objective: To evaluate the sparing effects of fentanyl and maropitant on sevoflurane minimum alveolar concentrations that block autonomic responses (MACBAR) and the hemodynamic and electroencephalographic responses to noxious stimuli in dogs.

Methods: The sevoflurane MACBAR was determined in 5 healthy male Beagles with or without continuous infusions of fentanyl and maropitant. Then, intermittent noxious stimulation was applied at 1.

When multiple instance learning meets foundation models: Advancing histological whole slide image analysis.

Deep multiple instance learning (MIL) pipelines are the mainstream weakly supervised learning methodologies for whole slide image (WSI) classification. However, it remains unclear how these widely used approaches compare to each other, given the recent proliferation of foundation models (FMs) for patch-level embedding and the diversity of slide-level aggregations. This paper implemented and systematically compared six FMs and six recent MIL methods by organizing different feature extractions and aggregations across seven clinically relevant end-to-end prediction tasks using WSIs from 4044 patients with four different cancer types.
