Critical Involvement of the Thioredoxin Reductase Gene () in Gallinarum-Induced Systemic Infection in Chickens.

serovar Gallinarum biovar Gallinarum (SG) causes fowl typhoid, a notifiable infectious disease in poultry. However, the pathogenic mechanism of SG-induced systemic infection in chickens remains unclear. Thioredoxin reductase (TrxB) is a redox protein crucial for regulating various enzyme activities in serovar, but the role in SG-induced chicken systemic infection has yet to be determined.

A novel yeast-based biosensor for the quick determination of Deoxynivalenol.

Mycotoxins are commonly found in food materials and severely threaten human health. Antibodies play a key role as a part of immunological techniques in detecting mycotoxins. Therefore, highly specific antibodies and detection techniques against mycotoxins need to be developed for advancements in medical research.

pathogenicity island-14 is a critical virulence factor responsible for systemic infection in chickens caused by .

serovar Gallinarum () is an important host-specific pathogen that causes fowl typhoid, a severe systemic, septicemic, and fatal infection, in chickens. causes high morbidity and mortality in chickens and poses a significant burden and economic losses to the poultry industry in many developing countries. However, the virulence factors and mechanisms of -induced systemic infection in chickens remain poorly understood.

Multi-omics approaches to understand pathogenicity during potato early blight disease caused by .

Potato early blight (PEB), a foliar disease of potato during the growing period, caused by sp., is common in major potato-producing areas worldwide. Effective agents to control this disease or completely resistant potato varieties are absent.

Nanobody-based magnetic chemiluminescence immunoassay for one-pot detection of ochratoxin A.

Ochratoxin A (OTA) contamination seriously threatens food safety and human health and requires sensitive and rapid tools for monitoring. In this study, a convenient enzyme-linked immunosorbent assay based on Avi-labeled nanobody Nb-2G/streptavidin-alkaline phosphatase and magnetic beads (MBS-ELISA) was established for the sensitive detection of OTA, which could be used for one-pot detection without immobilization. After optimization, the 50% inhibitory concentration (IC50) and the lowest limit of detection value of the MBS-ELISA was 1.

A novel biosensor based on antibody controlled isothermal strand displacement amplification (ACISDA) system.

The overuse of antibiotics has aroused widespread concern in recent decades. Their residues in food and environment may pose potential risks to human health. Therefore, highly sensitive and rapid detection methods of antibiotics are urgently needed.

Quantitative assessment of the degree of deep venous reflux of the lower extremities.

Objective: We sought to quantitatively evaluate the degree of deep venous reflux of the lower extremities using colour Doppler velocity profile (CDVP) technology.

Methods: Deep venous reflux volume was examined using CDVP in 79 limbs of 66 patients who were admitted to our hospital between July 1999 and July 2000 with primary, deep venous, valvular incompetence. Reflux data were statistically described and analyzed.
