The effect of social norms on vegetarian choices is moderated by intentions to follow a vegetarian diet in the future: Evidence from a laboratory and field study

Frontiers in Psychology, 2023
Social norms could be a tool in dietary transition toward more sustainable diets, but the results of social norms interventions aimed at encouraging the selection of plant-based foods to date have been inconsistent.

Production of Indole and Indole-Related Compounds by the Intestinal Microbiota and Consequences for the Host: The Good, the Bad, and the Ugly

Microorganisms, 2022
The intestinal microbiota metabolic activity towards the available substrates generates myriad bacterial metabolites that may accumulate in the luminal fluid. Among them, indole and indole-related compounds are produced by specific bacterial species from

Phenotypic Characterization of pncA Mutants of Mycobacterium tuberculosis [PDF]

Antimicrobial Agents and Chemotherapy, 2000
ABSTRACT We examined the correlation of mutations in the pyrazinamidase (PZase) gene ( pncA ) with the pyrazinamide (PZA) resistance phenotype with 60 Mycobacterium tuberculosis isolates. PZase activity was determined by the method of Wayne (L. G. Wayne, Am. Rev. Respir. Dis.

Detection of Mutations in pncA in Mycobacterium tuberculosis Clinical Isolates from Nepal in Association with Pyrazinamide Resistance

Current Issues in Molecular Biology, 2022
Without the proper information on pyrazinamide (PZA) susceptibility of Mycobacterium tuberculosis (MTB), PZA is inappropriately recommended for the treatment of both susceptible and multidrug-resistant tuberculosis (MDR-TB) in Nepal.

Mycobacterium smegmatis Has Two Pyrazinamidase Enzymes, PncA and PzaA [PDF]

Journal of Bacteriology, 2000
ABSTRACT The Mycobacterium smegmatis pncA gene, encoding nicotinamidase/pyrazinamidase, was identified. While it was similar to counterparts from other mycobacteria, the M. smegmatis PncA had little homology to the other M.

pncA Mutations in Pyrazinamide-Resistant Mycobacterium tuberculosis Isolates in Portugal [PDF]

Antimicrobial Agents and Chemotherapy, 2004
ABSTRACT The nucleotide sequences of the pncA genes within 55 multidrug-resistant pyrazinamide-resistant Mycobacterium tuberculosis clinical isolates were determined. Fifty-three out of the 55 isolates were pyrazinamidase (PZase) negative. Four strains contained a wild-type

Metallochaperones Are Needed for Mycobacterium tuberculosis and Escherichia coli Nicotinamidase-Pyrazinamidase Activity. [PDF]

, 2020
Mycobacterium tuberculosis nicotinamidase-pyrazinamidase (PZAse) is a metalloenzyme that catalyzes conversion of nicotinamide-pyrazinamide to nicotinic acid-pyrazinoic acid. This study investigated whether a metallochaperone is required for optimal PZAse

Plant and Animal Protein Intakes Largely Explain the Nutritional Quality and Health Value of Diets Higher in Plants: A Path Analysis in French Adults

Frontiers in Nutrition, 2022
Diets higher in plants are associated with lower risks of chronic diseases. However, animal foods, which are rich in protein, are also rich in some important minerals and vitamins.

Plant to animal protein ratio in the diet: nutrient adequacy, long-term health and environmental pressure

Frontiers in Nutrition, 2023
BackgroundAnimal and plant protein sources have contrasting relationships with nutrient adequacy and long-term health, and their adequate ratio is highly debated.ObjectiveWe aimed to explore how the percentage of plant protein in the diet (%PP) relates ...

An Enhanced Perturbational Study on Spectral Properties of the Anderson Model [PDF]

, 1995
The infinite-$U$ single impurity Anderson model for rare earth alloys is examined with a new set of self-consistent coupled integral equations, which can be embedded in the large $N$ expansion scheme ($N$ is the local spin degeneracy).
