Bioequivalence study of fluticasone propionate nebuliser suspensions in healthy Chinese subjects.

Background: Fluticasone propionate is a synthetic trifluoro-substituted glucocorticoid, a highly selective glucocorticoid receptor agonist. Fluticasone propionate nebuliser suspensions is an inhaled corticosteroid with the low systemic bioavailability which provides a low risk (benefit outcome without the adverse effects that accompany systemically administered corticosteroids), referred as a first-line preventive agent for patients with persistent asthma. China has become one of the countries with the highest asthma mortality rate in the world in the past years.

Simulated deep space exposure on seeds utilizing the MISSE flight facility.

The MISSE-Seed project was designed to investigate the effects of space exposure on seed quality and storage. The project tested the Multipurpose Materials International Space Station Experiment-Flight Facility (MISSE-FF) hardware as a platform for exposing biological samples to the space environment outside the International Space Station (ISS). Furthermore, it evaluated the capability of a newly designed passive sample containment canister as a suitable exposure unit for biological samples for preserving their vigor while exposing to the space environment to study multi-stressor effects.

Cell therapy with human IL-10-producing ILC2s limits xenogeneic graft-versus-host disease by inhibiting pathogenic T cell responses.

Interleukin-10 (IL-10)-producing group 2 innate lymphoid cells (ILC2) regulate inflammatory immune responses, yet their therapeutic potential remains largely unexplored. Here, we demonstrate that cell therapy with human ILC2 inhibits pathogenic T cell responses in humanized mouse models of graft-versus-host disease (GVHD), resulting in reduced GVHD severity and improved overall survival without limiting the graft-versus-leukemia effect. ILC2 conferred superior protection from GVHD than IL-10 ILC2s, and blocking IL-10 and IL-4 abrogated ILC2 protective effects, indicating that these cytokines are important for the protective effects of ILC2.

Identification of two QTLs for web blotch resistance in peanut (Arachis hypogaea L.) based on BSA-seq.

Background: Peanut (Arachis hypogaea L.) is a globally important oilseed and cash crop. Web blotch is one of the most important peanut foliar diseases, causing severe yield losses worldwide.

Haematological setpoints are a stable and patient-specific deep phenotype.

The complete blood count (CBC) is an important screening tool for healthy adults and a common test at periodic exams. However, results are usually interpreted relative to one-size-fits-all reference intervals, undermining the precision medicine goal to tailor care for patients on the basis of their unique characteristics. Here we study thousands of diverse patients at an academic medical centre and show that routine CBC indices fluctuate around stable values or setpoints, and setpoints are patient-specific, with the typical healthy adult's nine CBC setpoints distinguishable as a group from those of 98% of other healthy adults, and setpoint differences persist for at least 20 years.

BTK regulates microglial function and neuroinflammation in human stem cell models and mouse models of multiple sclerosis.

Neuroinflammation in the central nervous system (CNS), driven largely by resident phagocytes, has been proposed as a significant contributor to disability accumulation in multiple sclerosis (MS) but has not been addressed therapeutically. Bruton's tyrosine kinase (BTK) is expressed in both B-lymphocytes and innate immune cells, including microglia, where its role is poorly understood. BTK inhibition may provide therapeutic benefit within the CNS by targeting adaptive and innate immunity-mediated disease progression in MS.

Nationwide, Couple-Based Genetic Carrier Screening.

Background: Genomic sequencing technology allows for identification of reproductive couples with an increased chance, as compared with that in the general population, of having a child with an autosomal recessive or X-linked genetic condition.

Methods: We investigated the feasibility, acceptability, and outcomes of a nationwide, couple-based genetic carrier screening program in Australia as part of the Mackenzie's Mission project. Health care providers offered screening to persons before pregnancy or early in pregnancy.

Micro/Nano Hierarchical Dumbbell-like and Micropapillae Structure Improves Light Absorption and Facilitates Anti-icing/Deicing Performance.

The emergence of ice formation and accretion presents significant challenges, catalyzing an urgent need for clean and efficient anti-icing solutions. Solar energy, a powerful and sustainable resource, can be integrated with the micronano-structured superhydrophobic surface to enhance anti-icing and deicing performance through the solar photothermal effect, overcoming the limitations of a traditional superhydrophobic surface. Herein, inspired by bamboo and lotus leaves, a synergetic photothermal anti-icing superhydrophobic surface (PASS) has been developed.

Circulating mtNFPs Are Associated with ARDS after CPB and Regulate Endothelial Barrier through FPR2.

Cardiopulmonary bypass (CPB) increases the risk of acute respiratory distress syndrome (ARDS) due to endothelial cell (EC) barrier dysfunction. However, the specific role of mitochondrial N-formyl peptides (mtNFPs) in ARDS following CPB remains unexplored. Here, we investigated the differential expression of circulating mtNFPs in patients after CPB, focusing on the novel role of FPR2 in ECs.

Altered bile acids profile is a risk factor for hyperandrogenism in lean women with PCOS: a case control study.

The levels of fasting-state serum bile acids (BAs) in individuals with polycystic ovary syndrome (PCOS) differ from those of control subjects. However, there is a lack of research on the BAs profile in lean women with PCOS and whether these changes are linked to the host metabolism. Therefore, our objective was to investigate the synthesis and metabolism of serum BAs in lean women with PCOS and assess the correlation between BAs and clinical characteristics.

Wildfire-sourced fine particulate matter and preterm birth risks in Brazil: A nationwide population-based cohort study.

Wildfire-specific particulate matter with diameters ≤ 2.5 µm (PM) is the key component of wildfire smoke, with potentially higher toxicity than PM from other sources. In this nationwide population-based cohort study, we included 22,163,195 births from Brazil during 20102019.

Purpose: To compare the myelin water fraction (MWF) measurements between 3 T and 7 T and between in vivo and ex vivo human brains, and to investigate the relationship between multi-echo gradient-echo (mGRE)-based 3D MWF and myelin content using histological staining, which has not been validated in the human brain.

Methods: In this study, we performed 3D mGRE-based MWF measurements on five ex vivo human brain hemispheres and five healthy volunteers at 3 T and 7 T with 1 mm isotropic resolution. The data were fitted with the based on a three compartment complex-valued model to estimate MWF.

NovoBoard: A Comprehensive Framework for Evaluating the False Discovery Rate and Accuracy of De Novo Peptide Sequencing.

De novo peptide sequencing is one of the most fundamental research areas in mass spectrometry-based proteomics. Many methods have often been evaluated using a couple of simple metrics that do not fully reflect their overall performance. Moreover, there has not been an established method to estimate the false discovery rate (FDR) of de novo peptide-spectrum matches.

Integrated cytological and transcriptomic analyses provide new insights into restoration of pollen viability in synthetic allotetraploid Brassica carinata.

Upregulation of genes involved in DNA damage repair and sperm cell differentiation leads to restoration of pollen viability in synthetic allotetraploid B. carinata after chromosome doubling. Apart from the well-known contribution of polyploidy to crop improvement, polyploids can also be induced for other purposes, such as to restore the viability of sterile hybrids.

Bioequivalence of Meloxicam Nanocrystal Injection in Healthy Chinese Volunteers.

This single-center, randomized, open, two-preparation, single-dose, two-period, self-crossover trial aimed to assess the bioequivalence and safety of the test (T) preparation compared to the reference (R) preparation following intravenous injection in healthy subjects under fasting conditions. Twenty-four healthy subjects were enrolled in the study and subjects were randomly divided into two groups at a 1:1 ratio and were administered once per period, with an 8-day washout period. During each period, serum drug concentrations were detected for pharmacokinetic analysis and adverse events were recorded for safety analysis.

Expression of heterosis in photosynthetic traits in F1 generation of sorghum () hybrids and relationship with yield traits.
