While -phenylenediamine antioxidants (PPDs) pose potential risks to aquatic ecosystems, their environmental persistence and transformation remain ambiguous due to the undefined nature of PPD C-N bond hydrolysis. Here, we investigated the hydrolysis patterns of PPDs by analyzing their hydrolysis half-lives, hydrolysis products around neutral pH (pH 6.0-7.

Unraveling Reactive Nitrogen Emissions in Heavy-Duty Diesel Vehicles across Evolving Standards and Cheating Tactics.

Reactive nitrogen (Nr) emissions significantly affect air quality and the nitrogen cycle in ecosystems. Heavy-duty diesel vehicles (HDDVs), as major sources of these emissions, exhibit complex emission characteristics because of the combined effects of different driving conditions and aftertreatment technologies. This study first investigated the emission factors (EFs) of Nr species, including NO, NO, HONO, NO, and NH, from HDDVs under different emission standards (China IV/V/VI) and cheating strategies, with a particular focus on the impact of selective catalytic reduction (SCR) systems.

Association of First Trimester Nuchal Septations With Abnormal Pregnancy Outcomes.

This retrospective study included 311 patients who had increased nuchal translucency (NT ≥3 mm) or nuchal septations (NSs) during the first trimester from January 2018 to December 2020. These patients were divided into 3 groups: (1) patients with NT thickness between 3 and 5 mm and without NS (NT 3-5 mm group, n = 131), (2) patients with NT thickness >5 mm and without NS (NT >5 mm group, n = 105), and (3) patients with NS (NS group, n = 75). The incidence of abnormal pregnancy outcomes was 92.

Chromosome-level Genome Assembly and Annotation of the Arctic Moss Ptychostomum knowltonii.

The polar regions host a diverse array of moss species that have evolved to thrive extreme environments. These mosses exhibit remarkable adaptations, including tolerance to freezing temperatures, desiccation, and ultraviolet radiation.

Microglia programmed cell death in neurodegenerative diseases and CNS injury.

Programmed cell death (PCD) has emerged as a critical regulatory mechanism in the initiation and progression of various pathological conditions. PCD in microglia, including necroptosis, pyroptosis, apoptosis, ferroptosis, and autophagy, occurs in a variety of central nervous system (CNS) diseases. Dysregulation of microglia can lead to excessive tissue damage or neuronal death in CNS injury.

Combined transcriptome and metabolome analysis revealed the antimicrobial mechanism of Griseorhodin C against Methicillin-resistant Staphylococcus aureus.

Background: Both gallstone disease and sleep disorders are important public health problems. Few studies to date have investigated the associations between sleep and gallstone disease in humans. This study aimed to assess whether sleep factors (sleep time, sleep amounts, trouble sleeping) were associated with gallstone disease in the United States adults.

Evaluating the diagnostic potential of SOCS3 in copper metabolism for acute myocardial infarction.

Acute myocardial infarction (AMI) represents a critical cardiovascular condition necessitating rapid and precise diagnostic strategies. This study investigates the diagnostic implications of genes involved in copper metabolism homeostasis in AMI. We identified genes related to copper metabolism and AMI from Genecards and GEO databases, conducting differential gene analysis via R software.

Biomimetic Morphogenesis of Strontium Chitosan-Gelatin Composite Aggregates via EPD and Biomineralization in vitro and in vivo.

Introduction: Biomineralization has been increasingly adopted for the synthesis of advanced materials with superior properties. Hierarchical architecture growth mimicking biomineralization has been studied using various organic molecules to template inorganic materials with controlled morphology. In our previous study, self-assembled Sr/CS/G(SrCO-chitosan-gelatin) aggregates were fabricated using electrophoretic deposition (EPD).

Intermittent hypoxia training improves cerebral blood flow without cognitive impairment.

Objective: Brief exposure to intermittent hypoxia has been shown to potentially induce protective effects in the body. Animal studies suggest that intermittent hypoxia could increase cerebral blood flow and confer resistance to subsequent hypoxic-ischemic injury, yet clinical investigations are limited. This study aimed to evaluate the impact of a moderate short-term intermittent hypoxia protocol on cerebral blood flow and cognitive performance.

A Novel Insight into Postmenopausal Hypercholesterolemia: Carnitine as a Key Player.

Postmenopausal women (post-MW) are at a heightened risk of cardiovascular diseases, including hypercholesterolemia. This study aimed to investigate metabolomic variations to identify potential markers and targets for postmenopausal hypercholesterolemia. Sixty-two female volunteers aged 40-65 were recruited for this study.

Impacts of Five Different Drying Methods on Volatile Organic Compounds in Mulberry Fruits.

The mulberry fruit is edible and medicinal, and it is commonly referred to as the "best health product of the 21st century". The purpose of this study was to find out whether different drying methods affect the quality of mulberry fruits and the main nature of the volatile organic compounds (VOCs) they contain. This study used vacuum freeze-drying (VFD), vacuum drying (VD), sun drying (SD), hot-air drying (HAD), and microwave drying (MD) to treat fresh mulberry fruits.

On-Off Switching of Singlet Self-Trapped Exciton Emission Endows Antimony-Doped Indium Halides with Excitation-Wavelength-Dependent Luminescence.

Excitation-wavelength-dependent (Ex-De) emitters are a fascinating category of luminescent materials whose emission properties vary with the wavelength of the light used for excitation. Antimony (Sb)-doped indium (In)-based metal halides are efficient light emitters; however, the peak fluorescence emission of most Sb-activated In-halide remains independent of the excitation wavelength. Here, the study introduces a new Sb-doped In-halide cluster, (BDPA)InCl:Sb (BDPA = CHN, benzyldimethylphenylammonium), which demonstrates efficient Ex-De emission originating from the on-off switchable fluorescence behavior of singlet self-trapped exciton (STE) in 5-coordinate Sb dopant.

BCAT1 contributes to the development of TKI-resistant CML.

Purpose: Although most of chronic myeloid leukemia (CML) patients can be effectively treated by the tyrosine kinase inhibitors (TKIs), such as Imatinib, TKI-resistance still occurs in approximately 15-17% of cases. Although many studies indicate that branched chain amino acid (BCAA) metabolism may contribute to the TKI resistance in CML, the detailed mechanisms remains largely unknown.

Method: The cell proliferation, colony formation and in vivo transplantation were used to determined the functions of BCAT1 in leukemogenesis.
