Environmental contamination and risks of organic UV filters: Source, discharge, analytical methods and implications for ecological and human health.

Organic Ultraviolet Filters (OUVFs), commonly used in sunscreens, cosmetics and industrial products to prevent ultraviolet radiation damage, are increasingly detected in the environment due to their widespread use and persistence. This has raised concerns over their toxicity and environmental impact, leading to the classification of OUVF 2-(2H-Benzotriazol-2-yl)-4,6-ditertpentylphenol (UV-328) as a persistent organic pollutant under the Stockholm Convention in 2023. In this review, current knowledge on the usage, discharge and environmental contamination of OUVFs is briefly discussed.

16p11.2 CNV gene Doc2α functions in neurodevelopment and social behaviors through interaction with Secretagogin.

Copy-number variations (CNVs) of the human 16p11.2 genetic locus are associated with neurodevelopmental disorders, including autism spectrum disorders (ASDs) and schizophrenia. However, it remains largely unclear how this locus is involved in the disease pathogenesis.

CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library databases were searched to collect the randomized controlled trial(RCT) of single Hirudo prescriptions for ICVD from the inception of the databases to May 2022. The quality of the included literature was evaluated by Cochrane risk of bias tool.

Biochanin A ameliorated oleate-induced steatosis in HepG2 cells by activating the SIRT3/AMPK/ULK-1 signaling pathway.

The targets of FD were retrieved from GeneCards.

Basolateral amygdala activation enhances object recognition memory by inhibiting anterior insular cortex activity.

Noradrenergic activation of the basolateral amygdala (BLA) by emotional arousal enhances different forms of recognition memory via functional interactions with the insular cortex (IC). Human neuroimaging studies have revealed that the anterior IC (aIC), as part of the salience network, is dynamically regulated during arousing situations. Emotional stimulation first rapidly increases aIC activity but suppresses it in a delayed fashion.

A new phloroglucinol was isolated from 50% ethanol extract of Dryopteris fragrans by silica gel column chromatography, Sephadex LH-20 gel column chromatography, thin-layer chromatography(TLC), and preparative liquid column chromatography. On the basis of MS, ~1H-NMR, ~(13)C-NMR, and reference materials, compound 1 was identified as 2,5-cyclohexadien-1-one, 2-{[2,6-dihydroxy-4-methoxy-3-methyl-5-(1-isobutyl)phenyl]methyl}-3,5-dihydroxy-4,4-dimethyl-6-(1-oxobutyl)(1), and named disaspidin BB. Compound 1 was evaluated for its antibacterial activity.

A High-Fat High-Fructose Diet Dysregulates the Homeostatic Crosstalk Between Gut Microbiome, Metabolome, and Immunity in an Experimental Model of Obesity.

Scope: Ample evidence supports the prominent role of gut-liver axis in perpetuating pathological networks of high-fat high-fructose (HFF) diet induced metabolic disorders, however, the molecular mechanisms are still not fully understood. Herein, this study aims to present a holistic delineation and scientific explanation for the crosstalk between the gut and liver, including the potential mediators involved in orchestrating the metabolic and immune systems.

Methods And Results: An experimental obesity-associated metaflammation rat model is induced with a HFF diet.

Migration of mineral oil hydrocarbons from food contact papers into food simulants and extraction from their raw materials.

To determine the occurrence of mineral oil hydrocarbons (MOH) in food contact papers in China, and to investigate the potential sources of MOH contamination, a total of 159 food contact papers and raw materials were analysed by off-line solid-phase extraction-gas chromatography flame ionisation detection (SPE-GC-FID) and a GC-MS method. The migration of MOH from food contact papers into Tenax, olive oil or 50% ethanol under the worst foreseeable conditions of use was determined. The results indicated that the occurrence of MOH in China is of a potential health risk concerning the migration of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) which were detected in 82.

-- regulates cognitive functions in the hippocampus through complement component 3-dependent modulation of synaptic vesicle release.

microRNA-218 (miR-218) has been linked to several cognition related neurodegenerative and neuropsychiatric disorders. However, whether miR-218 plays a direct role in cognitive functions remains unknown. Here, using the miR-218 knockout (KO) mouse model and the sponge/overexpression approaches, we showed that -- but not -- could bidirectionally regulate the contextual and spatial memory in the mice.

Synaptotagmin-7 deficiency induces mania-like behavioral abnormalities through attenuating GluN2B activity.

Synaptotagmin-7 (Syt7) probably plays an important role in bipolar-like behavioral abnormalities in mice; however, the underlying mechanisms for this have remained elusive. Unlike antidepressants that cause mood overcorrection in bipolar depression, -methyl-d-aspartate receptor (NMDAR)-targeted drugs show moderate clinical efficacy, for unexplained reasons. Here we identified Syt7 single nucleotide polymorphisms (SNPs) in patients with bipolar disorder and demonstrated that mice lacking Syt7 or expressing the SNPs showed GluN2B-NMDAR dysfunction, leading to antidepressant behavioral consequences and avoidance of overcorrection by NMDAR antagonists.

Neonatal outcome in 29 pregnant women with COVID-19: A retrospective study in Wuhan, China.

Background: As of June 1, 2020, coronavirus disease 2019 (COVID-19) has caused more than 6,000,000 infected persons and 360,000 deaths globally.

The rat model of dampness obstructing spleen-stomach syndrome was established, and then the modeled rats were randomly divided into the model control group, Huoxiang Zhengqi Oral Liquid high and low dose groups, and natural recovery group according to gender and body weight, with 10 rats in each group. Another 10 rats were taken as blank control group.

Identification and characterization of tumorigenic circular RNAs in cervical cancer.

Circular RNAs (circRNAs) are a distinctive family of ncRNAs, and they function as key regulators in the initiation, development and progression of various diseases. However, the regulatory roles of circRNAs in the tumorigenesis of cervical cancer (CC) have not been fully understood. In this study, we identified a set of circRNAs in CC and paired normal tissues, using RNA sequencing data, and found that the cancer and normal tissues could be told apart by those differentially expressed (DE) circRNAs, indicating that circRNA expression profiles in CC were significantly different from those in the normal tissues.

Five New Alkaloids from the Roots of Sophora flavescens.

Five new quinolizidine alkaloids, including three sparteine-type alkaloids (1 - 3) and two cytisine-type alkaloids (4 and 5), along with four known ones, were isolated from the roots of Sophora flavescens. Their structures were determined by extensive spectroscopic techniques including IR, UV, NMR, and HR-ESI-MS. All the compounds were evaluated for their antibacterial activities against Staphylococcus aureus and Escherichia coli.
