Fatty acid esters of hydroxy fatty acids (FAHFAs) are emerging bioactive lipids in edible oils, but their trace-level presence and matrix complexity hinder accurate analysis. Here, we designed a novel chemoselective probe piperazine-modified silica () that specifically captures FAHFAs while removing almost totally triglycerides in a one-step labeling reaction. The probe enabled single-batch sample pretreatment within 30 min, integrating capture, purification, and signal amplification.

Infectious hypodermal and hematopoietic necrosis virus (IHHNV) is a major pathogen that severely impacts the shrimp aquaculture industry, and has lead to significant economic losses. Understanding the molecular response mechanisms of shrimp against IHHNV infection is crucial for developing effective disease control strategies. In order to deeply explore the molecular mechanism of Litopenaeus vannamei responds to IHHNV infection, this study screened the shrimp proteins interacting with IHHNV via the yeast two-hybrid system.

Obesity correlates with gut microbiota dysbiosis, with beneficial microbial intervention emerging as a promising therapeutic strategy for obesity-associated metabolic disorders. In previous studies, we screened F3-2 ( F3-2) with the ability to inhibit lipid accumulation, but its biofilm-forming capacity and consequent impacts on probiotic functionality remain uncharacterized. Based on this, this study characterized the biofilm formation capacity of F3-2, analyzing its structural organization along with extracellular matrix composition.

Young human de novo genes, recently emerging from non-coding regions, are expected to contribute to human-specific traits and diseases. However, systematic explorations of this connection have been lacking. Here, we report 37 recently originated de novo genes in humans, with their evolution and characteristics defined within an updated genomic context.

Background: Tunneled cuffed catheters (TCCs) are critical vascular access tools for hemodialysis patients, but they are associated with complications such as tunnel infections (TIs) and catheter-related bloodstream infections (CRBSIs). Current guidelines recommend removing infected TCCs, but this can exacerbate central venous stenosis (CVS) and complicate subsequent catheter reinsertion. This case series proposes a staged management protocol for complex TCC tunnel abscess infections complicated by CVS.

The androgen receptor (AR) signaling drives prostatic development and carcinogenesis, whereas the zinc finger homeobox 3 (ZFHX3) transcription factor modulates these processes. AR upregulates ZFHX3 transcription, but whether and how ZFHX3 plays a role in the AR signaling is unknown. RNA-seq was used to identify AR target genes that were also affected by ZFHX3 loss.

Ulcerative colitis (UC) is a long-lasting inflammatory bowel disease that causes inflammation in the intestines and triggers autoimmune responses. This study aims to identify immune-related biomarkers for ulcerative colitis (UC) and explore potential therapeutic targets. First, we downloaded the expression profiles of datasets GSE87466, GSE87473, and GSE92415 from the GEO database.

In this network meta-analysis (NMA), we aimed to evaluate the relative efficacy of robotic nipple-sparing mastectomy (RNSM), conventional nipple-sparing mastectomy (CNSM), and endoscope-assisted nipple-sparing mastectomy (ENSM), each combined with immediate prosthetic breast reconstruction (IPBR), for the treatment of breast cancer. Relevant studies published up to June 15, 2024, were identified through searches of PubMed, Embase, the Cochrane Library, and Web of Science. Data extracted from these studies were analyzed using Stata 15.

Severe fever with thrombocytopenia syndrome (SFTS) is a viral infection primarily found in Asia, with a case fatality rate of about 10%. Despite its increasing prevalence, the underlying pathogenic mechanisms remain poorly understood, limiting the development of effective therapeutic interventions. We employed an untargeted metabolomics approach using liquid chromatography-mass spectrometry (LC-MS) to analyze serum samples from 78 SFTS patients during the acute phase of their illness.

Background: University-based programs should aim to teach dental students about practice procedures to gain insight into day-to-day activities. This study introduces a newly established comprehensive dental professional curriculum, including an additional 9-week comprehensive rotation internship program.

Methods: All dental students from the Department of General Dentistry II under Peking University School and Hospital of Stomatology (PKUSS) who completed a specialized internship in the five research areas (endodontics, periodontics, prosthodontics, oral and maxillofacial surgery, and pediatric dentistry), including an additional 9-week comprehensive rotation, were invited to participate in the survey (total n = 253 in years 2022-2024).

When a fault occurs on a line, it is necessary to quickly isolate the fault to improve the safety and reliability of the transmission system. Due to the lack of effective ability to identify the nature of faults, the traditional automatic reclosing scheme is highly likely to cause the circuit breaker to reclose onto a permanent fault in practical applications. This will then cause a secondary impact on the power transmission system, seriously threatening the stable operation of the system.

Although anti-CD19 chimeric antigen receptor (CAR-T) cells demonstrate high response rates in relapsed/refractory B-cell lymphomas, a considerable proportion of patients eventually encounter disease progression or relapse. The short-term and long-term outcomes of CAR-T treatment are intricately linked to the tumor microenvironment (TME), wherein macrophages with polarized characteristics can exhibit either anti-tumorigenic or pro-tumorigenic roles. Despite evidence implicating the crucial involvement of macrophages in CAR-T cell-treated lymphoma, their dynamic distribution and immune function related to lymphoma progression remain poorly understood.
