Materials And Methods: This retrospective study included 291 COVID-19 patients with complete clinical data between December 2022 and March 2024, and some (n=82) of them developed secondary aspergillus infection after admission. Patients were divided into training (n=162), internal validation (n=69) and external validation (n=60) cohorts.

Interplay between energy metabolism and NADPH oxidase-mediated pathophysiology in cardiovascular diseases.

Sustained production of reactive oxygen species (ROS) and an imbalance in the antioxidant system have been implicated in the development of cardiovascular diseases (CVD), especially when combined with diabetes, hypercholesterolemia, and other metabolic disorders. Among them, NADPH oxidases (NOX), including NOX1-5, are major sources of ROS that mediate redox signaling in both physiological and pathological processes, including fibrosis, hypertrophy, and remodeling. Recent studies have demonstrated that mitochondria produce more proteins and energy in response to adverse stress, corresponding with an increase in superoxide radical anions.

Real-time analgesic efficacy and factors determining drug requirements of combined spinal-epidural analgesia for labor: a prospective cohort study.

Purpose: Combined spinal-epidural analgesia (CSEA) is effective but not sufficient for labor pain. This study was conducted to assess the real-time analgesic efficacy, side effects of anesthetic drug dosage, and maternal satisfaction in labor to provide reference for the optimization of labor analgesia.

Tumor microenvironment activation amplify oxidative stress promoting tumor energy remodeling for mild photothermal therapy and cuproptosis.

Tumor metabolic reprogramming requires high levels of adenosine triphosphate (ATP) to maintain treatment resistance, which poses major challenges to chemotherapy and photothermal therapy. Especially, high levels of ATP promote copper ion efflux for limiting the curative effect of cuproptosis. Here, an HS-responsive mesoporous CuCl(OH)-loading chemotherapeutic cisplatin (CDDP) was synthesized, and the final nanoparticle, CDDP@CuCl(OH)-CDs (CDCuCDs), was encapsulated by electrostatic action with carbon dots (CDs).

HS-driven chemotherapy and mild photothermal therapy induced mitochondrial reprogramming to promote cuproptosis.

The elevated level of hydrogen sulfide (HS) in colon cancer hinders complete cure with a single therapy. However, excessive HS also offers a treatment target. A multifunctional cascade bioreactor based on the HS-responsive mesoporous CuCl(OH)-loaded hypoxic prodrug tirapazamine (TPZ), in which the outer layer was coated with hyaluronic acid (HA) to form TPZ@CuCl(OH)-HA (TCuH) nanoparticles (NPs), demonstrated a synergistic antitumor effect through combining the HS-driven cuproptosis and mild photothermal therapy.

A study of forensic genetics: ITO index distribution and kinship judgment between two individuals.

According to Mendel's law of genetic separation, there must be a certain blood relationship between members of the same family, and two individuals with blood relations must have the following three situations, that is, there are two homologous genes (I denotes), one homologous gene (T denotes), and no homologous genes (O denotes), which is the ITO index for calculating the blood relationship between two individuals. The AGGU Expressmarker 22 kit, ABI 3500 genetic analyzer, and GeneMapper ID-X v1.5 software were used to statistically analyze the ITO index of the gene locus of 5 kinds of samples, 28 pairs of monozygotic twins (MT), 4,000 pairs of parent-offspring (PO), 392 pairs of full sibling (FS), 138 pairs of half-siblings (HS) (including grandchildren, uncles, and nephews) and 3,500 pairs of unrelated individuals (UI).

Association between serum total bilirubin and Alzheimer's disease: A bidirectional Mendelian randomization study.

Oxidative stress plays an important role in the pathogenesis of Alzheimer's disease (AD).
