Using HBV monomers and reconstituted cell line DNA (SNU398, Hep3B, and PLC/PRF/5), the HBV-NGS assay demonstrated high coverage uniformity, reproducibility across HBV genotypes A-D, and 0.1% sensitivity for detecting iDNA.

Investigating Older Adults' Response to Climate Change.

Older adults are both vulnerable to the impacts of climate change and uniquely positioned to contribute to climate action. However, their ability and willingness to engage vary significantly due to health disparities, financial constraints, and cultural factors. To ensure inclusivity, climate policies must reflect these differences and empower older adults to participate effectively.

Detection and characterization of Hepatitis B virus double-stranded linear DNA-derived covalently closed circular DNA in chronic hepatitis B patients.

Background And Aims: Hepatitis B virus (HBV) generates a double-stranded linear DNA (dslDNA) byproduct during replication. This dslDNA can undergo intermolecular and intramolecular nonhomologous end-joining (NHEJ) recombination, resulting in viral integration and dslDNA derived covalently closed circular DNAs (dsl-cccDNAs), respectively. The insertions and deletions (INDELs) at the end-joining site around the direct repeat (DR) 1 motif have been used to differentiate dsl-cccDNA from the authentic cccDNA.

The diagnostic value of contrast-enhanced ultrasound combined with clinicopathological features in microinvasive ductal carcinoma .

Background: Ductal carcinoma in situ with microinvasion (DCISM) represents 1% of all breast cancer cases and is arguably a more aggressive subtype of ductal carcinoma in situ (DCIS). Preoperative evaluation of DCISM usually relies on core needle biopsy, and non-invasive evaluation methods are relatively limited. This study aims to explore the features of conventional ultrasound (US) and contrast-enhanced ultrasound (CEUS) in DCISM and to analyze the US and clinicopathological predictors of infiltrating components.

QTL mapping and BSR-seq revealed loci and candidate genes associated with the sporadic multifoliolate phenotype in soybean (Glycine max).

The QTLs and candidate genes governing the multifoliolate phenotype were identified by combining linkage mapping with BSR-seq, revealing a possible interplay between genetics and the environment in soybean leaf development. Soybean, as a legume, is typified by trifoliolate leaves. Although multifoliolate leaves (compound leaves with more than three leaflets each) have been reported in soybean, including sporadic appearances in the first compound leaves in a recombinant inbred line (RIL) population from a cross between cultivated soybean C08 and wild soybean W05 from this study, the genetic basis of this phenomenon is still unclear.

Impacts of February climate conditions in the Gobi Desert on March dust activities in the northern East Asia.

Amid ongoing global warming, intense dust storms continue to plague regions despite efforts to understand and mitigate their impacts. This study explores the connection between surface temperature (ST) and precipitation (PRE) in the Gobi Desert (GD) during February and their subsequent effects on March dust concentrations across northern East Asia. Our analysis reveals a clear pattern: higher February ST combined with lower PRE in GD correlates with increased dust levels in March, with ST effects predominantly in northern areas of dust sources compared to PRE.

Primer exchange reaction assisted CRISPR/Cas9 cleavage for detection of dual microRNAs with electrochemistry method.

An electrochemical sensor assisted by primer exchange reaction (PER) and CRISPR/Cas9 system (PER-CRISPR/Cas9-E) was established for the sensitive detection of dual microRNAs (miRNAs). Two PER hairpin (HP) were designed to produce a lot of extended PER products, which could hybridize with two kinds of hairpin probes modified on the electrode and initiate the cleavage of two CRISPR/Cas9 systems guided by single guide RNAs (sgRNAs) with different recognition sequences. The decrease of the two electrochemical redox signals indicated the presence of dual-target miRNAs.

Jurassic shuotheriids show earliest dental diversification of mammaliaforms.

Shuotheriids are Jurassic mammaliaforms that possess pseudotribosphenic teeth in which a pseudotalonid is anterior to the trigonid in the lower molar, contrasting with the tribosphenic pattern of therian mammals (placentals, marsupials and kin) in which the talonid is posterior to the trigonid. The origin of the pseudotribosphenic teeth remains unclear, obscuring our perception of shuotheriid affinities and the early evolution of mammaliaforms. Here we report a new Jurassic shuotheriid represented by two skeletal specimens.
