Article Abstract
(Rs), a soil-borne fungal pathogen, can result in rice sheath blight (ShB), which causes yield loss. To prevent outbreaks of ShB and enhance the sustainability of rice production, it is critical to develop a rapid ShB detection method for specific, fast, and on-site disease management. In this study, a reagent for the rapid extraction of this pathogen was developed for on-site detection. The specificity and sensitivity of a novel SMS RS1-F/SMS RS1-R primer set and a ITS1/GMRS-3 reference primer set were tested, while four different extraction protocols for ShB were developed. Moreover, intraday and interday assays were performed to evaluate the reproducibility of the detection methods developed. The results indicated that all of the developed protocols are suitable for use in detecting ShB. In addition, all the samples of infected rice yielded positive Rs detection results when subjected to TaqMan probe-based real-time PCR and SYBR green-based real-time PCR (SMS RS1-F/SMS RS1-R) tests in which automatic magnetic bead-based DNA extraction was performed. These results indicated that the two molecular detection protocols were suitable for the field diagnosis of ShB for all asymptomatic and symptomatic rice samples.

Background: Genetic modifiers are believed to play an important role in the onset and severity of polycystic kidney disease (PKD), but identifying these modifiers has been challenging due to the lack of effective methodologies.
Methods: We generated zebrafish mutants of IFT140, a skeletal ciliopathy gene and newly identified autosomal dominant PKD (ADPKD) gene, to examine skeletal development and kidney cyst formation in larval and juvenile mutants. Additionally, we utilized ift140 crispants, generated through efficient microhomology-mediated end joining (MMEJ)-based genome editing, to compare phenotypes with mutants and conduct a pilot genetic modifier screen.

This work presents the development of a highly sensitive, selective, and efficient aptamer-based fluorescent sensor for detecting cortisol in human urine. Carbon quantum dots-nucleic acid aptamer (CQDs-Apt) synthesized with excellent photoluminescent properties and stability, were selected as the fluorescent probe. In the presence of MoS-NSs, CQDs-Apt adsorbed onto the surface of MoS-NSs via electrostatic and π-π interactions, leading to strong and rapid fluorescence quenching due to static quenching mechanism between them.

Gepotidacin, a novel, bactericidal, first-in-class triazaacenaphthylene antibacterial, was noninferior to nitrofurantoin in two pivotal trials (EAGLE-2 and EAGLE-3) in females with uncomplicated urinary tract infections (uUTIs). Using pooled data, gepotidacin activity and clinical efficacy were evaluated for subsets of molecularly characterized isolates in the microbiological Intent-to-Treat population. The subsets of isolates were characterized based on phenotypic/MIC criteria; all microbiological failure isolates were also characterized.

Molecular piezoelectrics have garnered significant attention in energy harvesting and sensing fields due to their high intrinsic piezoelectricity, low elastic properties, and excellent solution processability. Recent efforts have primarily focused on rationally tuning the piezoelectric performance of these materials through the molecular predesign of organic components. However, the regulation of piezoelectric properties via the central metal ion has remained relatively underexplored.

Background The prognostic value of baseline visual emphysema scoring at low-dose CT (LDCT) in lung cancer screening cohorts is unknown. Purpose To determine whether a single visual emphysema score at LDCT is predictive of 25-year mortality from all causes, chronic obstructive pulmonary disease (COPD), and cardiovascular disease (CVD). Materials and Methods In this prospective cohort study, asymptomatic adults aged 40-85 years with a history of smoking underwent baseline LDCT screening for lung cancer between June 2000 and December 2008.
