Genetic susceptibility to human brucellosis has so far been localized to variants of genes, which participate in the specific response and the innate immune response. The Nramp1 gene, which participates in the innate response, is related to susceptibility and protection in bovine brucellosis. We examined the polymorphism of the human NRAMP1 gene in 65 patients with brucellosis and 89 healthy controls and found no significant differences in the alleles studied. Thus, variants of the NRAMP1 gene do not appear to affect susceptibility or protection in human brucellosis.

The use of plant growth-promoting rhizobacteria (PGPR) for the bioremediation of heavy metal cadmium (Cd) and for enhancing plant growth in Cd-polluted soil is widely recognized as an effective approach. This study aimed to isolate Cd-resistant bacteria with plant growth-promoting (PGP) traits from the rhizosphere of vegetables subjected to metal contamination and to investigate the mechanisms associated with Cd adsorption as well as its impact on Cd uptake in lettuce. Six Cd-resistant bacterial strains were isolated from rhizosphere soil, among which the R27 strain exhibited the highest tolerance to Cd (minimum inhibitory concentration of 2000 mg/L) along with PGP traits, including phosphate solubilization (385.

Exosomal microRNAs (miRNAs) in circulation were recognized as potential biomarkers for the diagnosis of multiple diseases. However, its potential as a diagnostic hallmark for tuberculosis (TB) has yet to be explored. Here, we comprehensively analyze miRNA profiles in exosomes derived from the plasma of active TB patients and healthy persons to evaluate its efficacy in TB diagnosis.

Article Synopsis
  • Cadmium (Cd) is a harmful heavy metal that enters the food chain through plants, posing health risks to humans when consumed.
  • Researchers identified a specific protein called WAKL4 that helps plants tolerate Cd stress by regulating the uptake of this metal.
  • The study reveals that WAKL4 works by interacting with another protein, NRAMP1, to promote its degradation, thus reducing Cd absorption in plants, which could aid in developing crops that accumulate less Cd.

Article Synopsis
  • Salmonella enteritidis (SE) continues to cause significant economic losses in chicken production, emphasizing the need to study the host's genetic immune response to understand resistance and susceptibility to the disease.
  • The research aims to identify key immune-related genes and their pathways involved in resistance to SE by combining gene expression studies with computational analysis.
  • A two-phase experimental design is utilized, which includes bioinformatics tools to predict gene function and validate findings through real-time PCR to measure the expression of five candidate genes in infected and non-infected samples.

is a cadmium (Cd) and zinc (Zn) accumulator with potential for phytoextraction of soil contaminated with heavy metals. However, how Zn affects Cd accumulation in remains unclear. In this study, seedlings were treated with 100 μmol·L Zn (Zn100), 100 μmol·L Cd (Cd100), and the Zn and Cd combination (Zn100+Cd100) for 10 days under hydroponic culture.
