Structure-function coupling changes in first-episode, treatment-naïve schizophrenia correlate with cell type-specific transcriptional signature.

Background: First-episode schizophrenia (FES) is a complex and progressive psychiatric disorder. The etiology of FES involves genetic, environmental, and neurobiological factors. This study investigates the association between alterations in structural-functional (SC-FC) coupling and transcriptional expression in FES.

Macrophage extracellular traps promote tumor-like biologic behaviors of fibroblast-like synoviocytes through cGAS-mediated PI3K/Akt signaling pathway in patients with rheumatoid arthritis.

Rheumatoid arthritis is an autoimmune disease characterized by synovium hyperplasia and bone destruction. Macrophage extracellular traps are released from macrophages under various stimuli and may generate stable autoantigen-DNA complexes, as well as aggravate autoantibody generation and autoimmune responses. We aimed to investigate the role of macrophage extracellular traps on the biologic behaviors of rheumatoid arthritis fibroblast-like synoviocytes.

Conjoint Fascial Sheath Suspension for Severe Blepharoptosis through Palpebral Margin Incision.

Background: Conjoint fascial sheath suspension can achieve pleasing surgical efficacy and dynamic eyelid movement in the treatment of severe ptosis. In recent years, the palpebral margin incision technique has been applied for double-eyelid blepharoplasty, which is characterized by inconspicuous scarring, short convalescence, and natural-looking outcome. However, studies of the application of this technique in the treatment of ptosis are scarce.

Structural insights into the recognition of histone H3Q5 serotonylation by WDR5.

Serotonylation of histone H3Q5 (H3Q5ser) is a recently identified posttranslational modification of histones that acts as a permissive marker for gene activation in synergy with H3K4me3 during neuronal cell differentiation. However, any proteins that specifically recognize H3Q5ser remain unknown. Here, we found that WDR5 interacts with the N-terminal tail of histone H3 and functions as a "reader" for H3Q5ser.

Source water odor in one reservoir in hot and humid areas of southern China: occurrence, diagnosis and possible mitigation measures.

Background: Identifying typical odor-causing compounds is essential for odor problem control in drinking water. In this study, aiming at a major water source reservoir in hot and humid areas in southern China, which encountered seasonable odor problems in recent years, an integrated approach including comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC × GC-TOFMS), flavor profile analysis (FPA) and quantitative real-time polymerase chain reaction (qPCR) was adopted to investigate the odor occurrence.

Results: The results indicated that earthy-musty odor is blamed to the seasonable odor problems, and it is consistent with the complaints results from consumers.
