Estuarine and coastal environments have experienced dissolved oxygen (DO hereafter) depression and hypoxia due to increasingly intensified anthropogenic eutrophication and climate warming. This review compared diverse systems in Chinese coastal waters that experience DO depletion or hypoxia, aiming to identify essential aspects in advancing the abilities in comprehensively understanding DO dynamics across systems that span wide ranges of physical and biogeochemical environments. The coastal DO depression and relevant ecological consequences around the world are generally overviewed.

The development of carbon-encapsulated alloy catalysts, through a rational design that integrates highly active Me-N-C sites, is essential for improving the reaction kinetics of both oxygen reduction (ORR) and oxygen evolution reactions (OER). This advancement is pivotal for the progression of efficient rechargeable zinc-air batteries (RZABs). In this study, we investigates a CoNi alloy decorated N-doped carbon nanotube (CoNi-NCNT) electrocatalyst using a dual-ligand strategy.

Leydig cells (LCs) injury is often irreversible upon discovery; hence, early identification of risk factors for injury is crucial. The ubiquitous plasticizer di-2-ethylhexyl phthalate (DEHP) in the environment has been shown to potentially cause damage to LCs. However, the underlying mechanisms remain unclear.

Background: As one of the most prevalent chronic non-communicable diseases affecting aging males, the burden of benign prostatic hyperplasia is growing over the world. Our study aims at investigating the potential relationships between various blood biomarkers and benign prostatic hyperplasia (BPH) in middle-aged and older men in European and East Asian population cohorts.

Methods: We included 229 022 male adults from the UK Biobank (UKB) and 20 284 male adults from the China Health and Retirement Longitudinal Study (CHARLS) in this study.

Label-free quantitative proteomics profiles combined with biochemical analysis were applied in three spore release stages to investigate the proteome responses related to spore release inducing the quality loss of mushrooms. During the spore release, the mushrooms softened, and malondialdehyde (MDA) and total free amino acids accumulated, especially bitter amino acids. Among the 2720 identified proteins, aminoacyl-tRNA biosynthesis, oxidative phosphorylation, and other glycan degradation pathways were primarily implicated.

Background: Peripheral artery disease (PAD) patients after endovascular treatment (EVT) have a relatively high restenosis rate. However, this risk can be mitigated through precise risk assessment and individualized self-management intervention plans. Moreover, the number of predictive models for restenosis risk in PAD patients after EVT is gradually increasing, yet these results of study exhibit certain discrepancies, raising uncertainties regarding the quality and applicability in clinical practice and future research.

Article Synopsis
  • The study investigates the link between malnutrition and poor outcomes in patients with vertebrobasilar artery occlusion (VBAO) undergoing endovascular treatment (EVT).
  • Researchers analyzed data from 285 patients, using malnutrition assessment tools like CONUT, GNRI, and PNI to evaluate nutritional status.
  • The findings revealed that malnutrition significantly increased the risk of poor prognosis at 90 days, making it a valuable predictor when combined with traditional risk factors.

Glabridin (Gla) has been reported to have significant effects in scar treatment, and however, the water insolubility of Gla leads to its poor transdermal absorption ability, which affects its bioactivities. Therefore, we attempted to prepare the Gla dissolving microneedles (Gla-MN) to improve the absorbtion of Gla. After investigation of the 3 factors including the needle tip matrix concentration, the prescription concentration of backing material, and the dissolution method of Gla, we finally determined the process parameters of 10% hyaluronic acid (HA) as the needle tip and 5% polyvinyl alcohol (PVA) as the backing, according to which the Gla-MN was prepared with the good characteristics of high hardness, complete appearance and good in vitro dissolution ability.

  • - Siegesbeckia orientalis, a traditional Chinese medicine known as 'Xi-Xian Cao,' has been used since the Tang Dynasty and is grown in several Asian countries for its medicinal value.
  • - In August 2022, a large area of S. orientalis in Shaanxi Province, China exhibited stunting and leaf withering, with significant gall formation on roots and high densities of second-stage juvenile nematodes found in the soil.
  • - Morphological measurements of the nematodes' female, male, and juvenile stages were detailed, indicating specific sizes and characteristics for effective species identification and understanding of the plant's health.

Di-(2-ethylhexyl) phthalate (DEHP) might led to chronic and long-term effects on human organs due to its widespread use and bioaccumulation. Despite some cohorts reporting an association between DEHP exposure and BPH, its underlying mechanisms have not been investigated. Our findings indicate that exposure to DEHP or MEHP (main metabolites of DEHP in the human body) leads to increased prostate weights, elevated prostate index, and notable epithelial thickening in rats.

  • The Wnt/β-catenin signaling pathway is essential for important biological functions like development and cell growth, and its regulation is critical for normal physiological processes.
  • When this pathway is improperly activated due to mutations or other factors, it can lead to cancer development and progression.
  • Ongoing research is focused on creating therapies that target this pathway, with many new drugs being developed to improve cancer treatment outcomes by addressing the challenges associated with their use in therapy.

Article Synopsis
  • Coronary artery aneurysms (CAAs) come in two shapes: saccular (like a balloon) and fusiform (more pipe-shaped), and doctors are debating which shape is more likely to cause blood clots.
  • This study looked at how blood flows in these different shapes using special imaging technology and found that saccular CAAs had a higher risk of staying stagnant, which could lead to bigger problems like rupturing.
  • Although both shapes can cause clots, fusiform CAAs might block blood flow sooner, making them a bigger worry for patients.

Reactive oxygen species (ROS) constitute a spectrum of oxygenic metabolites crucial in modulating pathological organism functions. Disruptions in ROS equilibrium span various diseases, and current insights suggest a dual role for ROS in tumorigenesis and the immune response within cancer. This review rigorously examines ROS production and its role in normal cells, elucidating the subsequent regulatory network in inflammation and cancer.

Strong field ionization injects a transient vacancy in the atom which is entangled to the outgoing photoelectron. When the electron is finally detached, the ion is populated at different excited states with part of coherence information lost. The preserved coherence of matter after interacting with intense short pulses has important consequences on the subsequent nonequilibrium evolution and energy relaxation.

In recent years, the use of electronic vaping products (also named e-cigarettes) has increased due to their appealing flavors and nicotine delivery without the combustion of tobacco. Although the hazardous substances emitted by e-cigarettes are largely found to be much lower than combustible cigarettes, second-hand exposure to e-cigarette aerosols is not completely benign for bystanders. This work reviewed and synthesized findings on the second-hand exposure of aerosols from e-cigarettes and compared the results with those of the combustible cigarettes.

Perineural invasion (PNI) leads to the poor prognosis of head and neck squamous cancer (HNSCC) patients, but the mechanism of PNI remains unclear. Dickkopf-1 (DKK1), a secretory protein in the Wnt signaling pathway, was found indeed upregulated in HNSCC cells and tissues. Higher expression of DKK1 was statistically relevant to T stage, N stage, PNI, and poor prognosis of HNSCC.
