This study focuses on the regulatory effects of genes encoding the juvenile hormone (JH) receptor methoprene-tolerant () and transcription factor krüppel homolog 1 () on the reproductive capacity of male adults. and expression levels were analyzed in males fed on artificial diets with and without JH by quantitative real-time PCR, and the effects of and on male reproduction were analyzed by RNA interference technology. transcription levels in 5- and 10-day-old males fed with a JH-supplemented diet were lower than those without JH.

Background: The vast majority of men with CF (mwCF) are infertile. Improvements in assisted reproductive technology (ART) have made it possible for these patients to become biological fathers.
Methods: Data were examined for all male CF patients attending a large adult CF center over a 23-year period.

Egg injection has been used for decades to determine embryonic mortality and developmental effects of chemical exposures in birds. Specific egg injection methods affect how well these studies replicate the process of chemical delivery to the embryo via maternal deposition, yet few data are available to compare exposure-response relationships between egg injection and maternal transfer studies. This information gap creates uncertainty when considering egg injection studies for assessment of potential adverse effects in wild birds.

At present, in the context of the highly intensive development of livestock and poultry breeding, digital management is becoming increasingly important, and digital twin systems are gradually being applied. To solve the contradiction between data acquisition and sensor network congestion, a virtual acquisition method based on historical data and real-time reference of point data is proposed when constructing a digital twin system. Firstly, computational fluid dynamics (CFD) simulation was used to analyze and determine the temperature distribution and environmental characteristics inside the layer house, and the collection area was preliminarily divided according to the CFD simulation results.

Since late 2021, outbreaks of highly pathogenic avian influenza virus have caused a record number of mortalities in wild birds, domestic poultry, and mammals in North America. Wetlands are plausible environmental reservoirs of avian influenza virus; however, the transmission and persistence of the virus in the aquatic environment are poorly understood. To explore environmental contamination with the avian influenza virus, a large-volume concentration method for detecting infectious avian influenza virus in waterbodies was developed.
