-Structural Changes in Early-stage Parkinson's Disease with Resting Tremor at Node, Edge and Network Level.

Background: Resting tremor in Parkinson's disease (PD) is associated with the activity in the basal ganglia and cerebello-thalamo-cortical circuits/network. However, most insights stem from functional MRI research, and structural studies, which can provide basis for and constrain functional activity, remains limited.

Methods: We investigated the structural change in PD patients with resting tremor (PD-WR) from a network perspective.

Enforced activation of the CREB/KDM2B axis prevents alcohol-induced embryonic developmental delay.

Unintentional, early pregnancy alcohol consumption affects embryonic development. During the peri-implantation stage, coinciding with the transition from naive to primed pluripotency, the long isoform of KDM2B (KDM2BLF) underlies the de novo establishment of polycomb repressive complex (PRC) functions at promoters after fertilization. However, it remains unclear whether and how ethanol exposure affects this spatiotemporal chromatin setting.

OGT mediated HDAC5 O-GlcNAcylation promotes osteogenesis by regulating the homeostasis of epigenetic modifications and proteolysis.

Background: O-GlcNAc transferase (OGT) is responsible for attaching O-linked N-acetylglucosamine (O-GlcNAc) to proteins, regulating diverse cellular processes ranging from transcription and translation to signaling and metabolism. This study focuses on the role and mechanisms of OGT in osteogenesis.

Materials And Methods: We found that OGT is downregulated in osteoporosis by bioinformatics analysis, determined its role in osteogenic differentiation by using OGT inhibitors (or OGA inhibitors) as well as conditional knockout OGT mice in and in , and explored and specific mechanisms by quantitative proteomic analysis and RNA-seq, qRT-PCR, western blotting, immunofluorescence, H&E, ALP, ARS, Masson staining, IHC, micro CT, etc.

Mechanochemical synthesis and transformation of the polymorphic double carbonates fairchildite and buetschliite, (KCa(CO)): an X-ray powder diffraction study.

This study presents the mechanochemical synthesis of the two KCa(CO) polymorphs, fairchildite and buetschliite, from CaCO and KCO using a shaker mill. Unlike previous methods requiring high temperatures and prolonged heating, fairchildite, a high-temperature polymorph, is formed initially in all experiments, adhering to Ostwald's rule of stages. Notably, the transformation to the stable buetschliite phase can be achieved by varying milling parameters, particularly frequency and moisture content.

DcWRKY15 positively regulates anthocyanin biosynthesis during petal coloration in Dianthus caryophyllus.

Petal pigmentation in carnations is closely associated with the biosynthesis of anthocyanins. This biosynthetic process is tightly regulated by transcription factors, which activate or repress key genes involved in anthocyanin production. Here, we aim to explore the mechanisms involved in the transcriptional regulation of anthocyanin biosynthesis in carnation petals.

The relationship between indoor airborne culturable bacteria with passenger flow in 132 traffic stations during 2019-2020, China.

This study aims to provide technical support for the development of a rational administration strategy for indoor environment and passenger flow of stations. The analysis was conducted monitor data of long distance bus stations and train/high speed railway stations from the National project. The monitor and surveyed data included indoor airborne culturable bacteria (IAB), passenger flow, area and height of stations.

Efficacy of pH-Responsive Surface Functionalized Titanium Screws in Treating Implant-associated S. aureus Osteomyelitis with Biofilms Formation.

Implant-associated Staphylococcus aureus (S. aureus) osteomyelitis (IASO) leads to high orthopedic implant failure rates due to the formation of Staphylococcal abscess community within the bone marrow and bacterial colonization in the osteocyte lacuno-canalicular network (OLCN). To address this, antimicrobial peptides (HHC36)-loaded titania nanotubes (NTs) are developed on titanium screws (Ti-NTs-P-A), which integrate pH-responsive polymethacrylic acid to control HHC36 release for eradicating bacteria in IASO.

Consolidating the Oxygen Reduction with Sub-Polarized Graphitic Fe-N Atomic Sites for an Efficient Flexible Zinc-Air Battery.

The effectuation of the Zn-air battery (ZAB) is appealing for active and durable catalysts to kinetically drive the sluggish cathodic oxygen reduction reaction (ORR). Atomic metal-N-C sites are widely witnessed with Pt-like activity, but their demetalations still severely restrict the durability in ORR. Here we have profiled an ordered hierarchical porous carbon supported Fe-N single-atom (FeNC) catalyst by a template derivation method for efficient ORR and flexible ZAB studies.
