Article Synopsis
  • This study explores how Chinese cordyceps aqueous extracts (WCCs) protect mpc5 cells from injury caused by the chemotherapy drug adriamycin (ADM) by analyzing gene expression changes through transcriptomic analysis.
  • The researchers used various methods, including HPLC and RNA sequencing, to identify that WCCs help restore normal gene levels primarily in pathways related to one-carbon metabolism and cell signaling, which enhance cellular processes like DNA repair and immune function.
  • The findings suggest that WCCs offer new insights into potential treatments for kidney-related diseases, especially regarding how they interact with genes associated with human diseases.

Advancements in brain-machine interfaces (BMIs) have led to the development of novel rehabilitation training methods for people with impaired hand function. However, contemporary hand exoskeleton systems predominantly adopt passive control methods, leading to low system performance. In this work, an active brain-controlled hand exoskeleton system is proposed that uses a novel augmented reality-fused stimulus (AR-FS) paradigm as a human-machine interface, which enables users to actively control their fingers to move.

Background: Limited understanding of the diversity of variants in the cystic fibrosis transmembrane conductance regulator (CFTR) gene across ancestries hampers efforts to advance molecular diagnosis of cystic fibrosis (CF). The consequences pose a risk of delayed diagnoses and subsequently worsened health outcomes for patients. Therefore, characterizing the spectrum of CFTR variants across ancestries is critical for revolutionizing molecular diagnoses of CF.

β-arrestin-1 has been demonstrated to participate in the regulation of inflammatory reactions in several diseases. Thus, this study aimed to investigate the role of macrophage β-arrestin-1 in the pathogenesis and progression of ulcerative colitis (UC). A myeloid β-arrestin-1 conditional knockout mouse model was generated to explore the role of macrophage β-arrestin-1.

Our previous work demonstrated that the anisodamine (ANI) and neostigmine (NEO) combination produced an antiseptic shock effect and rescued acute lethal crush syndrome by activating the α7 nicotinic acetylcholine receptor (α7nAChR). This study documents the therapeutic effect and underlying mechanisms of the ANI/NEO combination in dextran sulfate sodium (DSS)-induced colitis. Treating mice with ANI and NEO at a ratio of 500:1 alleviated the DSS-induced colitis symptoms, reduced body weight loss, improved the disease activity index, enhanced colon length, and alleviated colon inflammation.

Fruit size is crucial for fruit trees, as it contributes to both quality and yield. However, the underlying mechanism of fruit size regulation remains largely unknown. Taking advantage of using a fruit double-sized bud mutant of Chinese jujube, "Jinkuiwang" and its wild type, "Jinsixiaozao", we carried out a comprehensive study on the mechanism of fruit size development in jujube.

Autophagy in atherosclerotic plaque macrophage contributes to the alleviation of atherosclerosis through the promotion of lipid metabolism. β-arrestins are multifunctional proteins participating various kinds of cellular signaling pathways. Here we aimed to determine the role of β-arrestin-1, an important member of β-arrestin family, in atherosclerosis, and whether autophagy was involved in this process.

Objective: To observe the therapeutic effect of Si-Ni-San (SNS) on interstitial cystitis/bladder pain syndrome (IC/BPS) in rats, and explore the possible regulatory mechanism of SNS on IC/BPS combined with transcriptome analysis.

Methods: An IC/BPS model of Sprague-Dawley (SD) rats was established with cyclophosphamide (CYP), and the SNS was extracted for treatment. The rats were divided into 4 groups (n = 10 in each group): Control group (blank), cyclophosphamide group (CYP group, CYP injection + normal saline gavage), lower-dose SNS group (LSNS group, CYP injection + 6 g/kg SNS gavage), and higher-dose SNS group (HSNS group, CYP injection + 12 g/kg SNS gavage).

Article Synopsis
  • - Researchers studied the contribution of polygenic scores (PGSs) for substance use (alcohol, cannabis, nicotine) in predicting outcomes beyond just family history of substance use disorders.
  • - The study found that while PGSs were generally effective predictors, their predictive power was influenced by demographic factors and genetic effects from parents, indicating less reliability in twin comparisons.
  • - The analysis showed that both PGSs and family history impacts on substance use were mediated by behavioral disinhibition observed in preadolescence, suggesting that disinhibition plays a key role in the relationship between genetics and substance use.

Developing a facile and time-saving method for preparing hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) electrocatalysts can accelerate the practical applications of hydrogen energy. In this study, halogen (X = F, Cl, Br and I) doped Ru-RuO on carbon cloth (CC) (X-Ru-RuO/MCC) was synthesized via an ultrafast microwave-assisted method for 30 s. Particularly, the doped Br (Br-Ru-RuO/MCC) significantly improved the electrocatalytic performances of the catalyst through the regulation of electronic structures.

  • Tobacco and alcohol use contribute significantly to global mortality rates, with heritability playing a key role in these behaviors.
  • This study utilized genetic data from a diverse population of 3.4 million individuals, including 21% non-European ancestry, to identify genetic variants linked to tobacco and alcohol use.
  • Findings showed that while increased genetic diversity improved the identification of genomic loci, polygenic risk scores were less effective across different ancestries, underscoring the need for larger and more diverse genetic datasets for better predictive outcomes.

Ferritinophagy is a type of autophagy mediated by nuclear receptor activator 4 (NCOA4), which plays a role in inducing ferroptosis by regulating iron homeostasis and producing reactive oxygen species in cells. Under physiological conditions, ferritinophagy maintains the stability of intracellular iron by regulating the release of free iron. Studies have demonstrated that ferritinophagy is necessary to induce ferroptosis; however, under pathological conditions, excessive ferritinophagy results in the release of free iron in large quantities, which leads to lipid peroxidation and iron-dependent cell death, known as ferroptosis.

Background: Polysaccharides are important active ingredients in Ophiocordyceps gracilis with many physiological functions. It can be obtained from the submerged fermentation by the anamorph (Paraisaria dubia) of Ophiocordyceps gracilis. However, it was found that the mycelial pellets of Paraisaria dubia were dense and increased in volume in the process of fermentation, and the center of the pellets was autolysis due to the lack of nutrient delivery, which extremely reduced the yield of polysaccharides.

Using formed metal complexes of [Fe(bipy)] or [Ni(bipy)] (bipy = 2,2'-bipyridine) as templates, four new Ag-Bi-X (X = I and Br) compounds are first isolated in the metal-complex-decorated heterometallic halobismuthate family, namely [M(bipy)]AgBiI (M = Fe (), Ni ()), [Fe(bipy)]AgBiBr (), and [Ni(bipy)]AgBiBr (). Compounds - feature discrete [AgBiX] anions, exhibiting three polymorphisms that may be ascribed to the different stackings and the flexible condensations of [BiX] octahedrons and [AgX] tetrahedra/[AgX] triangles. UV-vis diffuse reflectance analyses reveal that they are narrow band gap semiconductor materials (ca.
