Porphyrin-centered metal organic frameworks (MOFs) exhibit remarkable potential in ECL sensing applications.

Phosphorylation-Regulated Dynamic Phase Separation of HIP-55 Protects Against Heart Failure.

Background: Heart failure (HF), which is the terminal stage of many cardiovascular diseases, is associated with low survival rates and a severe financial burden. The mechanisms, especially the molecular mechanism combined with new theories, underlying the pathogenesis of HF remain elusive. We demonstrate that phosphorylation-regulated dynamic liquid-liquid phase separation of HIP-55 (hematopoietic progenitor kinase 1-interacting protein of 55 kDa) protects against HF.

A triphenylamine-based fluorescent probe with phenylboronic acid for highly selective detection of Hg and CHHg in groundwater.

Mercury is a highly toxic heavy metal and it poses a serious threat to the natural environment and human health. Thus, selective detection of trace mercury ( inorganic mercury and methylmercury) in the environment is critical yet challenging. Herein, we describe the rational design and facile synthesis of a new triphenylamine-based phenylboronic acid fluorescent probe (TPA-PBA) for selective detection of Hg and CHHg.

Is it safe for the spinal metastasis patients with preoperative deep vein thrombosis to use low-molecular-weight heparin before surgery? A prospective study.

Spine surgeons should weigh the risks of anticoagulants against their benefits in preventing deep venous thrombosis (DVT), as they may increase the risk of bleeding. Spinal metastasis patients undergoing decompression with fixation are at a high risk for DVT, which may occur preoperatively. Therefore, anticoagulants should be administered preoperatively.

Adaptor protein HIP-55-mediated signalosome protects against ferroptosis in myocardial infarction.

Ischemic heart disease is a leading cause of death worldwide. Myocardial infarction (MI) results in cardiac damage due to cell death and insufficient cardiomyocyte self-renewal. Ferroptosis, a novel type of cell death, has recently been shown as a key cause of cardiomyocyte death after MI.

Tcf12 is required to sustain myogenic genes synergism with MyoD by remodelling the chromatin landscape.

Muscle stem cells (MuSCs) are essential for skeletal muscle development and regeneration, ensuring muscle integrity and normal function. The myogenic proliferation and differentiation of MuSCs are orchestrated by a cascade of transcription factors. In this study, we elucidate the specific role of transcription factor 12 (Tcf12) in muscle development and regeneration based on loss-of-function studies.

Prevalence and risk factors for venous thromboembolism in spinal metastasis patients undergoing decompression with internal instruments: Prospective cohort study.

Objective: re is paucity in the literature on the epidemiological evidence of pulmonary thromboembolism (PE) and deep venous thrombosis (DVT) in spinal metastatic tumor patients. The aim of our study was to identify the incidence and risk factors for VTE in spinal metastasis patients treated with decompression with internal instruments.

Methods: We prospectively investigated the occurrence of VTE after decompression with internal fixations in 80 spinal metastasis patients.

H3K27ac chromatin acetylation and gene expression analysis reveal sex- and situs-related differences in developing chicken gonads.

Background: Birds exhibit a unique asymmetry in terms of gonad development. The female left gonad generates a functional ovary, whereas the right gonad regresses. In males, both left and right gonads would develop into testes.

Transcriptional dynamics of the circulating chicken primordial germ cells revealing key genes in cell adhesion and proliferation prior to gonad colonization.

Primordial germ cells (PGCs), precursors to sperms and oocytes, are responsible for the transfer of genetic information to the next generation. The PGCs arise far away from the developing gonad and thus have to migrate across the embryo to reach their site of function. The migration of PGCs from extraembryonic regions to the genital ridges is accomplished through distinct routes among different species.

The Clinical Effect of a Combination of Mouse Nerve Growth Factor and Methylcobalamin to Treat Lumbar Disc Herniation with Foot Drop: A Retrospective Cohort Study.

Objective: To investigate the clinical effect of mouse nerve growth factor (mNGF) and methylcobalamin (MeCbl) for the treatment of lumbar disk herniation (LDH) with foot drop.

Methods: A total of 46 patients suffering from LDH with foot drop who underwent transforaminal lumbar interbody fusion (TLIF) surgery in our department from January 2015 to December 2017 were retrospectively analyzed. We divided these patients into two groups according to the different postoperative treatment which independently selected by patients after signing informed consent form: one group of 25 patients was treated with MeCbl alone (Group MeCbl), the other group of 21 patients was treated with a combination of mNGF and MeCbl (Group MeCbl+mNGF).

A single-model quality assessment method for poor quality protein structure.

Background: Quality assessment of protein tertiary structure prediction models, in which structures of the best quality are selected from decoys, is a major challenge in protein structure prediction, and is crucial to determine a model's utility and potential applications. Estimating the quality of a single model predicts the model's quality based on the single model itself. In general, the Pearson correlation value of the quality assessment method increases in tandem with an increase in the quality of the model pool.

Src mediates β-adrenergic receptor induced YAP tyrosine phosphorylation.

The Hippo pathway is a newly identified pathway and evolutionarily conserved from flies to humans mainly regulating cell proliferation. Transcriptional co-activator Yes-associated protein (YAP) functions as a major downstream effector and key node of the Hippo pathway. Phosphorylation of YAP is critical to regulate YAP activity and its corresponding functions.

Multi-omic analysis reveals HIP-55-dependent regulation of cytokines release.

HIP-55 (HPK1 [hematopoietic progenitor kinase 1] -interacting protein of 55 kDa) contains an actin-depolymerizing factor homology (ADF-H) domain at the N-terminus and a src homology 3 (SH3) domain at the C-terminus, which plays an important role in the T cell receptor (TCR) and B-cell receptor (BCR) signaling and immune system. In our previous studies, HIP-55 was found to be highly expressed in several types of tumors and function as a novel oncogenic signaling hub that regulates tumor progression and metastasis through defined functional domains, actin-binding and SH3 modules. However, the wider functions and mechanisms of HIP-55 are still unclear.

Dynamics of cardiomyocyte and muscle stem cell proliferation in pig.

The cardiac and skeletal muscle tissues are both striated and contractile but their intrinsic cellular properties are distinct. The minimal cardiomyocyte proliferation and the lack of cardiac stem cells directly leads to poor heart repair in adult mammals. But in skeletal muscle, the robust proliferation of widespread muscle stem cells support efficient muscle regeneration.

Risk Factors for Incidence and Prognosis in Chondrosarcoma Patients with Pulmonary Metastasis at Initial Diagnosis.

BACKGROUND The incidence and prognostic factors of chondrosarcoma patients have been reported in early studies. However, the association between risk factors and the incidence or prognosis of chondrosarcoma patients with pulmonary metastasis remains unclear. Therefore, we assessed these risk factors among chondrosarcoma patients with pulmonary metastasis.

Polyethylene-glycol-coated gold nanoparticles improve cardiac function after myocardial infarction in mice.

Gold nanoparticles (AuNPs) are widely used for drug delivery because of their unique biological properties, such as their safety and ability to prolong drug action. Some studies have demonstrated that AuNPs accumulate in the heart, especially during pathological processes. Therefore, it is very important to understand the effect of AuNPs on the heart.
