Article Synopsis
  • Plastics aging decreases resistance to microbial degradation, and the mealworm Tenebrio molitor can biodegrade polystyrene (PS) effectively, but how aging affects this process is not well-studied.
  • In a 24-day study, various pre-treatments (freezing with UV, UV only, and freezing) were used on PS microplastics, resulting in slightly better PS consumption and mass reduction compared to pristine PS.
  • The study found that while aging treatments slightly improved PS biodegradation, they significantly affected the gut microbial diversity of the mealworms and their metabolic pathways, showing their capacity to adapt to altered PS plastics.

The increasing prevalence of infections related to methicillin-resistant Staphylococcus aureus (MRSA) necessitates the exploration of innovative therapeutic strategies that diverge from conventional antibiotic treatments. This is imperative to effectively combat resistance and manage these infections. The adoption of antivirulence strategies has emerged as a particularly promising avenue.

In the search for novel succinate dehydrogenase inhibitor (SDHI) fungicides to control , thirty-five novel pyrazole-4-carboxamides bearing either an oxime ether or an oxime ester group were designed and prepared based on the strategy of molecular hybridization, and their antifungal activities against five plant pathogenic fungi were also investigated. The results indicated that the majority of the compounds containing oxime ether demonstrated outstanding antifungal activity against and some compounds also displayed pronounced antifungal activities against and . Particularly, compound exhibited the most promising antifungal activity against with an EC value of 0.

Objective: To identify different subgroups of nursing professional commitment among nursing undergraduates and to analyze the related factors of the different subgroups.

Methods: A cross-sectional study using the professional commitment scale with 430 nursing undergraduates was conducted. Latent profile analysis was used to explore the nursing students' professional commitment subgroups and using multivariate logistic regression to analyze the related factors of nursing professional commitment.

() infection causes dramatic harm to human health as well as to livestock development. As an important virulence factor, alpha-hemolysin (hla) is critical in the process of infection. In this report, we found that bavachin, a natural flavonoid, not only efficiently inhibited the hemolytic activity of hla, but was also capable of inhibiting it on transcriptional and translational levels.

Article Synopsis
  • The study focuses on the challenge of drug-resistant Staphylococcus aureus (S. aureus) and highlights hispidulin, which inhibits the hemolytic activity of the bacteria without affecting its growth or causing resistance.* -
  • Hispidulin demonstrated the ability to inhibit the transcription and expression of alpha-hemolysin (hla), a key virulence factor, and had a protective effect against cell damage caused by S. aureus in lab tests.* -
  • In animal studies, hispidulin showed effectiveness in protecting against pneumonia induced by S. aureus, and it worked synergistically with the antibiotic cefoxitin, suggesting its potential as a treatment for S. aureus infections.*

The resistance of () to various antibiotics has increased dramatically due to the misuse of antibiotics, and thus the development of new anti-infective drugs with new targets is urgently needed to combat resistance. Caseinolytic peptidase P is a case in hydrolase that regulates the virulence level of . Here, we found that nepetin, a small-molecule compound from traditional Chinese herbal flavonoids, effectively inhibits ClpP activity.

Yellow and dark mealworms (Tenebrio molitor and Tenebrio obscurus) biodegrade commercial polyethylene (PE) materials at a high rate. We examined the impact of physical and chemical properties on biodegradation using high purity microplastics (MPs). These included high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE), all with different weight average molecular weights (M) and different crystallinity degrees in T.

Copper is vital for various life processes, whereas severely toxic at excess level. Intracellular copper homeostasis is strictly controlled by a set of transporters and chaperones encoded by the copper homeostasis genes. Increasing evidence has shown that copper is usually overloaded in multiple malignancies, including pancreatic cancer, which has an extremely poor prognosis.

Pertuzumab is a monoclonal antibody for the treatment of breast cancer. The aim of this study was to compare the pharmacokinetics, immunogenicity and safety of the test preparation SHR-1309 injecta and the reference preparation Perjeta® in healthy Chinese male subjects. In this randomized, double-blind, single dose, two-way, parallel bioequivalence trial, a total of 80 qualified Chinese male subjects were selected and randomly divided into two groups.

Article Synopsis
  • The study investigated the bioequivalence, immunogenicity, and safety of adalimumab injecta (a biosimilar of Humira®) compared to Humira® in healthy Chinese males.
  • A total of 164 participants received either adalimumab or Humira® through injection, and various parameters such as drug concentration, antibody levels, and physical health indicators were measured.
  • Results showed that adalimumab and Humira® met bioequivalence standards, with similar levels of immunogenicity and safety, indicating they can be considered equivalent for clinical use.

Alzheimer's disease (AD), one of the most common forms of dementia, is primarily ascribed to the cholinergic deficits and neuronal dysfunction. Magnolol (Mag), a bioactivator extracted from Magnolia officinalis, has protective effects on cholinergic neurons, but the specific mechanism remains unknown. To further evaluate the therapeutic effects of Mag on the learning and memory impairment in a scopolamine (Scop)-induced mouse model, the passive avoidance and the Morris water maze tests, the measurement of the ratio of brain/hippocampus to body weight, activities of acetyl cholinesterase (AChE), superoxide dismutase (SOD), total nitric oxide synthase (total NOS) and the content of methane dicarboxylic aldehyde (MDA) in hippocampus homogenate as well as the immunefluorescence staining of the AChE positive nerve fibers were performed.
