Self-disclosure and reproductive concerns among breast cancer female patients: the chain mediation model of couples' cancer-related communication problems and relationship intimacy.

Purpose: Reproductive concerns are prevalent in the female breast cancer patient population and increase existential distress. Although self-disclosure significantly correlated reproductive concerns, the exact mechanism of action is unknown. Based on previous theoretical studies on couples' cancer-related communication problems and intimacy in couples, this study constructed a chain mediation model to investigate whether the two variables mediate the relationship between self-disclosure and reproductive concerns.

PKM2 knockout facilitates the activation of the AMPK/KLF4/ACADVL pathway, leading to increased oxidative degradation of fatty acids in TNBC.

This study unveils PKM2 as a master metabolic coordinator in triple-negative breast cancer (TNBC), governing the glycolysis-lipolysis balance through the AMPK/KLF4/ACADVL axis. We demonstrate stage-specific PKM2 upregulation in TNBC, with CRISPR/Cas9 knockout inducing dual metabolic reprogramming-suppressed glycolysis and activated lipid catabolism. Mechanistically, PKM2 ablation triggers AMPK-dependent nuclear translocation of KLF4, which directly activates ACADVL (mitochondrial β-oxidation rate-limiting enzyme), explaining lipid droplet depletion.

Trifluoroacetic Acid Induced a Cyclophilin D-Dependent Cognitive Impairment in Mice.

Studies have linked inhalation anesthesia and surgery to increased cognitive impairment, particularly in the elderly. Our previous research showed that isoflurane, but not desflurane, affected cognitive function in mice by modulating cyclophilin D (CypD), a key regulator of the mitochondrial permeability transition pore (mPTP) and mitochondrial function. Both anesthetics metabolize into trifluoroacetic acid (TFA), which is associated with cognitive deficits.

Picolinamide Functionalization on Carbon Nitride Edges for Enhanced Charge Separation and Photocatalytic Hydrogen Evolution.

The periodical distribution of N and C atoms in carbon nitride (CN) not only results in localized electrons in each tri-s-triazine unit, but oxidation and reduction sites are in close contact spatially, resulting in severe carrier recombination. Herein, the hydrothermal method was first employed to synthesize carbon nitride (HCN), and then picolinamide (Pic) molecules were introduced at the edge of the carbon nitride so that the photo-generated electrons of the whole structure of the carbon nitride system were transferred from the center to the edge, which effectively promoted the separation of photo-generated carriers and inhibited the recombination of carriers in the structure. The introduced picolinamide not only changed the π-conjugated structure of the entire system but also acted as an electron-withdrawing group to promote charge transfer.

The Beneficial Role of the Thyroid Hormone Receptor Beta 2 () in Facilitating the First Feeding and Subsequent Growth in Medaka as Fish Larval Model.

During the early growth stages of fish larvae, there are significant challenges to their viability, so improving their visual environment is essential to promoting their growth and survival. Following the successful knockout of thyroid hormone receptor beta 2 () using Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 technology, there was an increase in the expression of UV opsin (short-wave-sensitive 1, ), while the expression of other cone opsins was significantly decreased. Further analysis of the retinal structure demonstrated that the knockout resulted in an increased lens thickness and a decreased thickness of the ganglion cell layer (GCL), outer plexiform layer (OPL), and outer nuclear layer (ONL) in the retina.
