Squamous metaplasia (SM) is common in smokers and associated with airway obstruction chronic obstructive pulmonary disease (COPD). A major mechanism of COPD thickening the small walls. We asked whether SM actively contributes to wall through alteration epithelial-mesenchymal interactions COPD. Using immunohistochemical staining, morphometry, fibroblast culture lung samples from patients; genome-wide analysis an vitro model SM; modeling human interactions, we provide evidence that SM,...

Protein post‐translational modifications (PTMs) play crucial roles in various cellular processes. Despite their significance, only a few PTMs have been extensively studied at the proteome level, primarily due to scarcity of reliable, convenient, and low‐cost sensing methods. Here, we present straightforward effective strategy for detecting on short peptides through host‐guest interaction‐assisted nanopore sensing. Our results demonstrate that identity 13 types specific position...

We have subcloned and expressed the N-terminal portion of recently sequenced metabotropic GABA receptor, GABA(B)R1a. This region receptor contains a complement protein-like amino acid sequence. The purified 140-residue recombinant protein fragment was soluble stable. Mass spectrometry indicated formation four disulfide bonds, as expected if two modules (CPs, also known SCRs, Sushi domains) are formed. circular dichroism spectrum unusual characteristic CPs. Differential scanning calorimetry...

Clostridium difficile (C.difficile) is an exclusively anaerobic, spore-forming, and Gram-positive pathogen that the most common cause of nosocomial diarrhea becoming increasingly prevalent in community. Because C. strictly spores can survive for months external environment contribute to persistence diffusion within healthcare Antimicrobial therapy disrupts natural intestinal flora, allowing develop into propagules colonize colon produce toxins, thus leading antibiotic-associated...

While the cytogenetic and genetic characteristics of childhood acute lymphoblastic leukemias (ALL) are well studied, less clearly understood contributing epigenetic mechanisms that influence leukemia phenotype. Our previous studies others identified gene mutation (RAS) DNA methylation (FHIT) to be associated with most common subgroup ALL, high hyperdiploidy (having five more chromosomes). We screened profiles, using a genome-wide high-dimension platform 166 ALLs 6 normal pre-B cell samples...

Unbalanced and degraded mixtures (UDM) are very common in forensic DNA analysis. For example, signals from criminal suspects masked by a large amount of victims, or cell-free fetal (cffDNA) maternal plasma is high background DNA. Currently, detecting minor these complex challenging. We developed new set SNP-SNP microhaplotypes with short amplicons, we successfully genotyped them using the method amplification-refractory mutation system PCR (ARMS-PCR) combined SNaPshot technology based on...

Alzheimer's disease (AD) is a serious public health crisis with only one current modifying treatment. The reduction of amyloid load by targeting γ-secretase (GS) has been leading approach in AD drug discovery and development. Despite the focus on GS inhibition, multiple inhibitors (GSIs) have failed clinical trials as result side effects including exacerbated cognitive decline. These are largely attributable to inhibition normal function. Standard enzyme target catalytic or allosteric sites...

It is generally believed that Carbapenem-resistant Enterobacterales (CRE) colonization primarily responsible for systemic infection in humans. However, there no consensus on whether decolonization should be recommended clinical practice. In China, the specific situation of CRE and consequent hospitalized patients necessitates further exploration. We conducted a cohort study analyzed various characteristics inpatients with intestinal colonization. A risk prediction model was established...
