High sensitivity detection of Hepatitis B virus RNA based on 3D-DNA nanomachine and protein nanopore sensing.

Serum Hepatitis B virus (HBV) RNA serves as a non-invasive biomarker for monitoring chronic hepatitis B and guiding treatment decisions. However, current diagnostic tests relying on Reverse Transcription Quantitative Polymerase Chain Reaction (RT-qPCR) require centralized facilities and tedious operational steps, and there is currently no standardized HBV RNA detection method. Herein, we describe the rapid amplification-free detection of HBV RNA in clinical serum samples via a nanopore sensing method.

Characterization of the G protein-coupled receptor FfGpr1-Gα-AC signal transduction in Fusarium fujikuroi and its role in gibberellin biosynthesis.

Aims: This study aimed to characterize the G protein-coupled receptor FfGpr1-Gα-AC transduction pathway and its role in regulating gibberellin (GA) metabolism in Fusarium fujikuroi.

Methods And Results: By constructing Ffgpr1 deletion and constitutively activated FfG2Q204 L mutants, we found that glucose-induced cAMP (cyclic Adenosine MonoPhosphate) synthesis was abolished in Ffgpr1Δ. Bimolecular fluorescence complementation confirmed membrane-localized FfGpr1-FfG2 and FfG2-AC interactions, with intensified fluorescence at septa.

Small molecule UCM05 inhibits HSV-2 infection via targeting viral glycoproteins and fatty acid synthase with potentiating antiviral immunity.

Herpes simplex virus type 2 (HSV-2) is a highly prevalent human pathogen worldwide that not only causes genital herpes but is also associated with severe health complications, such as neonatal infections and increased susceptibility to HIV. Currently, due to the lack of an effective HSV-2 vaccine and the emergence of more drug-resistant strains, there is an urgent need to develop effective, safe, and affordable anti-HSV-2 medications. The small molecule UCM05 is a novel inhibitor of fatty acid synthase (FASN) and filamentous temperature-sensitive protein Z (Ftsz), with antitumor and antibacterial effects.

Curcumin-loaded polyvinyl alcohol/nanocellulose/ nano zinc oxide nanofiber membranes with enhanced strength, moisture resistance, and antibacterial properties.

To meet the practical application demands of nanofiber membranes (NFMs) under humid conditions, a PVA/NC/ZnO NFM was successfully fabricated by incorporating nano zinc oxide (ZnO) into a polyvinyl alcohol (PVA)/nanocellulose (NC) matrix, combined with nitrogen-assisted thermal treatment. The synergistic effect of ZnO-induced heterogeneous nucleation and thermal processing significantly enhanced the crystallinity of the NFM (up to 49.71 %), improving its anti-swelling behavior and liquid absorption capacity-with an absorption rate of up to 1906 % for artificial blood.

Therapeutic potential of Triptolide in inhibiting breast cancer-induced bone destruction - PTHrP as a therapeutic target.

Introduction: Bone metastases are a common and severe complication in advanced breast cancer, affecting approximately 65% to 70% of patients and significantly reducing survival time. Osteolytic bone metastases, in particular, are challenging to manage due to their association with skeletal-related events (SREs) that accelerate disease progression and diminish the quality of life. These metastases are driven by a complex interaction between breast cancer cells and the bone microenvironment, leading to increased osteoclast activity and bone destruction.

Faecalibacterium prausnitzii (F.prausnitzii), a key commensal bacterium in the gut, has been recognized as a promising candidate for next-generation probiotics due to its potential wide-ranging health benefits.

Temporal variability in the diversity, function and resistome landscapes in the gut microbiome of broilers.

Understanding the dynamic and stability of gut microbiota over the course of production cycle of broiler chicken can help identify microbial features that associate with better health and productivity. In the present study, we profile the changes in the composition and stability of gut microbiota of commercially raised broilers at nine distinct time points using shotgun metagenomics and culturomics approaches. We demonstrate, within the first week post-hatching, a rapid decline in relative abundance of 122 pioneer microbial species including Bacteroides fragilis, Lachnospira eligens and Ruminococcus gnavus, accompanied by a substantial decrease in both microbial richness and diversity.

Polylactic acid aerogel with antibacterial, early warning and heat preservation functions applied to fresh trays.

Modeling multiple-criterion diagnoses by heterogeneous-instance logistic regression.

Mild cognitive impairment (MCI) is a prodromal stage of Alzheimer's disease (AD) that causes a significant burden in caregiving and medical costs. Clinically, the diagnosis of MCI is determined by the impairment statuses of five cognitive domains. If one of these cognitive domains is impaired, the patient is diagnosed with MCI, and if two out of the five domains are impaired, the patient is diagnosed with AD.
