The accumulation of amyloid plaques is a pathological hallmark of Alzheimer's disease (AD), in which ADAM10, the α-secretase that catalyzes APP and facilitates the non-amyloidogenesis pathway, plays an important role. We have previously reported that the expression of copine-7 (Cpne7) in the hippocampus of APP/PS1 mice is significantly upregulated by nicotine, whereas the potential role of CPNE7 in AD remains largely unknown. Here, we report that CPNE7 protein levels are significantly decreased in APP/PS1 mice and HEK293 cells stably expressing full-length APP.

Herein, a cellulose-based highly expandable sponge with arch-like lamellar structure was prepared by introducing interlayer calcium ion cross-linking in the sponges obtained by bi-directional freezing. The cellulose sponge, which has an arched layered structure that can withstand large stress strain, is compressed into small sizes to enter narrow and deep bleeding points, and then expand about 11 times after liquid absorption to apply sufficient and constant pressure on the bleeding points.

Background: The role of epigenetic aging in the environmental pathogenesis and prognosis of fibrotic interstitial lung disease (fILD) is unclear. We evaluated whether ambient particulate matter ≤2.5 μm (PM) and neighbourhood disadvantage exposures are associated with accelerated epigenetic aging, and whether epigenetic age is associated with adverse clinical outcomes in patients with fILD.

Plant genetic transformation is a pivotal and essential step in modifying important agronomic traits using biotechnological tools, which primarily depend on the efficacy of transgene delivery and the plant regeneration system. Over the years, advancements in the development of delivery methods and regeneration systems have contributed to plant engineering and molecular breeding. Recent studies have demonstrated that the efficiency of plant transformation can be improved by simultaneously delivering meristem-developmental regulators, utilizing virus-mediated gene editing, and executing non-sterile in planta manipulations.

The success of this protocol relies on NH·BH as the nitrogen source being considerably more convenient and NaHMDS being an excellent proton abstractor but not participating in the nucleophilic addition reaction. The reaction had a wide substrate scope containing bioactive molecules, and most of the substrates were efficiently amidated over 90% yields.

Drawing inspiration from cardiac muscle fiber arrangement, a three-dimensional (3D)-printed multi-layered microporous polycaprolactone (PCL) scaffold is created with interlayer angles set at 45° to replicate the precise structure of native cardiac tissue. Compared with the control group and 90° PCL scaffolds, the 45° PCL scaffolds exhibited superior biocompatibility for cell culture and improved hiPSC-CM maturation in calcium handling.

However, the underlying mechanisms necessitate further investigation. In this study, we established an ERα-deficient model in rBMSCs to elucidate the role of ERα in osteogenic differentiation and miRNA expression profiles.

In this study, shad scales, used for treating ulcers, scalds, and burns in traditional Chinese medicine, were exploited for type I collagen extraction. After self-assembly into hydrogels, the extracted collagen was subsequently freeze-dried to form collagen sponges.

Through the process of merging and correcting batch effects in the GSE120480 and GSE73714 datasets, we were able to identify 36 PRDEGs that exhibited significant expression differentiation in SPTB. Through functional enrichment and pathway analysis, their importance in amino acid transport and cytokine receptor interaction has been highlighted.

We hypothesized that high-frequency rTMS targeting these regions could alter pain anticipation and thereby reduce pain perception. In a double-blind, sham-controlled study, healthy participants received 10 Hz rTMS to M1, DLPFC, or a sham treatment.

African swine fever virus (ASFV) is the causative agent of African swine fever (ASF), a hemorrhagic illness with high fatality rates in domestic pigs that has resulted in a substantial socio-economic loss and threatens the global pork industry. Very few safe and efficient vaccines or compounds against ASF are commercially available, thus developing new antiviral strategies is urgently required. Targeted protein degradation (TPD) has emerged as one of the most innovative strategies for drug discovery.

There is evidence that the use of gene editing techniques to inhibit cell adhesion and establish an easily suspended cell line can improve vaccine yield; however, the mechanisms underlying MDCK cell adhesion are unclear. Methods: In this study, we used transcriptomics to analyse differentially expressed mRNAs and miRNAs in adherent and suspension cultures of MDCK cells.
