Reversibility of polystyrene nanoplastics-induced disruption of testosterone biosynthesis in mice: The role of histone modifications.

Nanoplastics (NPs) exposure could disrupt the synthesis of steroid hormones, thereby posing a potential threat to male reproductive health. However, the existing comprehension of the molecular mechanisms participating in this process remains limited, and the reversibility of NPs-triggered male reproductive toxicity is poorly understood. This investigation focused on the impact of histone modification on testosterone production in mice under long-term exposure to environmentally relevant doses of polystyrene nanoplastics (PS-NPs).

Theoretical studies of magneto-optical Kerr and Faraday effects in two-dimensional second-order topological insulators.

Optical approaches are useful for studying the electronic and spin structure of materials. Here, based on the tight-binding model and linear response theory, we investigate the magneto-optical Kerr and Faraday effects in two-dimensional second-order topological insulators (SOTI) with external magnetization. We find that orbital-dependent Zeeman term induces band crossings for SOTI phase, which are absent for trivial phase.

New progress with calcium-binding protein S100A16 in digestive system disease.

Introduction: This review summarizes and analyzes the abnormal expression and mechanism of S100A16 in digestive system diseases, which is expected to provide new ideas and methods for adjuvant treatment and prognosis evaluation of digestive system diseases.

Areas Covered: Based on original publications found in database systems (PubMed, Cochrane), we introduce the mechanism and research progress of S100A16 in digestive system tumors, inflammatory bowel disease and fatty liver.

Expert Opinion: S100A16 is closely related to the proliferation, migration, and invasion of digestive system tumor cells.

Investigating the influence of drone flight on the stability of cancer medicines.

Monoclonal Antibodies (mAbs) are being used in the treatment of both malignant and non-malignant diseases and whilst highly effective, certain products have very short expiry times. Clinical deterioration and supply chain disruption can often lead to wastage and there is a need to reduce this by improving efficiency in logistics practices between manufacturing sites and administration locations. This study aimed to investigate the influence of drone flight on the stability of cancer medicines.

Involvement of in Cuticle Sclerotization of the Whitefly, Middle East-Asia Minor 1.

Cuticle sclerotization is critical for insect survival. () is a phenol oxidase that plays a key role in cuticle formation and pigmentation in a variety of insects. However, the function of in whitefly, , remains unclear.

Effects of Time-Dependent Protein Restriction on Growth Performance, Digestibility, and mTOR Signaling Pathways in Juvenile White Shrimp .

A 6-week feeding strategy experiment was conducted to investigate the effects of time-dependent protein restriction and subsequent recovery on shrimp. Diets with protein levels of 43 and 36% were used as adequate and restricted diets, respectively. Shrimp with an initial body weight of 6.

Carbon framework microbelt supporting SnO as a high performance electrode for lithium ion batteries.

Facile preparation of rational SnO-based electrode materials with excellent electrochemical performance is highly desired for lithium ion batteries (LIBs). In this work, carbon framework microbelt supporting SnO nanoparticles (CFM-SnO) were prepared via a facile electrospinning technology and annealing treatment process. The as-synthesized CFM-SnO electrode exhibits high reversible capacity of 768 mAh g at 0.
