Background: The Hezuo (HZ) pig, a famous indigenous breed in China, is characterized by precocious puberty compared with foreign-introduced pig breeds. Sexual maturation is a complex physiological process, and in recent years, circular RNAs (circRNAs), a new class of noncoding RNAs with endogenous regulatory functions, have been shown to play important roles in regulating sexual maturation. However, the dynamic expression and regulatory mechanism of circRNAs during sexual maturation in HZ pigs remain unclear.

Article Synopsis
  • Researchers studied four related species in the Bradysia hilaris group from China and discovered a new species, Bradysia tianmuensis, along with another new species, Bradysia curvula.
  • Both new species share morphological similarities with an existing species, Bradysia noduspina, but additional analysis revealed differences in a related sample, leading to the identification of a third new species, Bradysia chikunae.
  • The study included a phylogenetic analysis using 31 COI sequences to support the classification of the new species, complemented by detailed images for identification purposes.

Adhesive composite hydrogels have received increasing attention in the fields of wearable sensors, electronic skin, and bioelectronic interfaces. However, combining good adhesiveness and high strength in a single composite hydrogel remains challenging. To address this issue, a polydopamine (PDA)-modified nanocellulose (PCNF)/polyacrylamide (PAM) composite hydrogel was developed, which exhibits good adhesiveness (40 kPa), good durability (1500 rpm), excellent frost resistance (-42 °C), and good sensitivity (GF = 1.

In clinical practice, timely and accurate diagnosis can effectively reduce unnecessary treatment, avoid high medical costs, and prevent adverse prognoses. However, some patients with malignant tumors and those with infection often exhibit similar symptoms, which are difficult to distinguish, posing challenges in accurate clinical diagnosis. Metagenomic next-generation sequencing (mNGS) technology has been widely applied to confirm the source of infection.

Acquired resistance to hormonal therapy, particularly enzalutamide (ENZ), remains a significant obstacle in the treatment of advanced bone metastatic prostate cancer. Here, it is demonstrated that under ENZ treatment, osteoblasts in the bone microenvironment secrete increased levels of extracellular matrix protein 1 (ECM1), which affects surrounding prostate cancer cells, promoting tumor cell proliferation and anti-androgen resistance. Mechanistically, ECM1 interacts with the enolase 1 (ENO1) receptor on the prostate cancer cell membrane, leading to its phosphorylation at the Y189 site.

Hepatocellular carcinoma (HCC) circulating tumor cells (CTCs) exhibit significant phenotypic heterogeneity and diverse gene expression profiles due to epithelial-mesenchymal transition (EMT). However, current detection methods lack the capacity for simultaneous quantification of multidimensional biomarkers, impeding a comprehensive understanding of tumor biology and dynamic changes. Here, the CTC Digital Simultaneous Cross-dimensional Output and Unified Tracking (d-SCOUT) technology is introduced, which enables simultaneous quantification and detailed interpretation of HCC transcriptional and phenotypic biomarkers.

Lysosomal acid lipase deficiency (LAL-D) is caused by mutations in the LIPA gene, which encodes the lysosomal enzyme that hydrolyzes triglycerides and cholesteryl esters to free fatty acids and free cholesterol. The objective of this study was to develop a curative single-treatment therapy for LAL-D using adeno-associated virus (AAV). Treatment at both early (1-2 days) and late (8-week) timepoints with rscAAVrh74.

The resistance mechanism of Gram-negative bacteria to the siderophore antibiotic cefiderocol is primarily attributed to carbapenemase and siderophore uptake pathways; however, specific factors and their relationships remain to be fully elucidated. Here, we constructed cefiderocol-resistant (CRKP) strains carrying different carbapenemases and knocked out siderophore genes to investigate the roles of various carbapenemases and siderophores in the development of cefiderocol resistance. Antimicrobial susceptibility testing revealed that both and significantly increased the minimum inhibitory concentration (MIC) of (KP) to cefiderocol, while showed a modest increase.

In response to the limitations of slow reaction kinetics and elevated overpotentials in the OER, a novel core-shell structured electrocatalyst, termed NiCo-ZIF-67@Fe-Co-Ni-PBA or NiCo-ZIF@PBA, has been developed. This material demonstrates exceptional catalytic performance, exhibiting a minimal overpotential of approximately 188 mV at 10 mA cm, alongside a Tafel slope of 109 mV dec. Its robust stability in a 1 M KOH solution during the OER operations is noteworthy.

Nipah virus (NiV) is a zoonotic paramyxovirus that has recently emerged as a crucial public health issue. It can elicit severe encephalitis and respiratory diseases in animals and humans, leading to fatal outcomes, exhibiting a wide range of host species tropism, and directly transmitting from animals to humans or through an intermediate host. Human-to-human transmission associated with recurrent NiV outbreaks is a potential global health threat.

This study examines the legality and appropriateness of keeping the multiple-choice question items of the Korean Medical Licensing Examination (KMLE) confidential. Through an analysis of cases from the United States, Canada, and Australia, where medical licensing exams are conducted using item banks and computer-based testing, we found that exam items are kept confidential to ensure fairness and prevent cheating. In Korea, the Korea Health Personnel Licensing Examination Institute (KHPLEI) has been disclosing KMLE questions despite concerns over exam integrity.

While growing two-dimensional covalent organic frameworks (2D COFs) on substrates holds promise for producing functional monolayers, the presence of many defects in the resulting crystals often hinders their practical applications. Achieving structural order while suppressing defect formation necessitates a detailed atomic-level understanding. The key lies in understanding the polymerization process with high nano-scale accuracy, which presents significant challenges.

Combined deficiency of coagulation factor V (FV) and factor VIII (FVIII) is a rare bleeding disease caused by variants in either lectin mannose binding 1 (LMAN1) or multiple coagulation factor deficiency 2 (MCFD2) gene. Reducing the level of FVIII by inhibiting the LMAN1-MCFD2 complex may become a new anticoagulant approach. We aimed to find a new therapeutic option for anticoagulation by RNA interference (RNAi) targeting LMAN1 and MCFD2.
