Antibacterial and Antioxidant Properties of Extracts of , a Plant of Northwestern Mexico, against Pathogenic Bacteria.

Introduction: Bacterial agents and oxidative reactions are involved in health and food preservation issues, and () can be a source of compounds with practical applications in both areas, but its investigation remains limited.

Materials And Methods: Butanolic (YBE) and aqueous (YAE) extracts were obtained from the stem of . The total saponin, phenolic, and flavonoid contents were analyzed in the YBE and YAE.

Prevalence and associated risk factors for Giardia and Cryptosporidium infections among children of northwest Mexico: a cross-sectional study.

Background: G. intestinalis and Cryptosporidium spp. are responsible for gastrointestinal infections worldwide.

Insufficient amounts and inadequate distribution of dietary protein intake in apparently healthy older adults in a developing country: implications for dietary strategies to prevent sarcopenia.

Background: Both low dietary protein intake and inadequate distribution of protein over the three mealtimes have been reported in older Caucasian adults, but the association between protein intake at each meal and muscle mass has not been studied. The purpose of this study was to evaluate dietary protein intake and distribution by mealtimes, and to explore their association with appendicular skeletal muscle mass in apparently healthy older adults.

Methods: This was a cross-sectional pilot study that included 78 people over the age of 60 years.

Persistence of intestinal parasitic infections during the national de-worming campaign in schoolchildren of northwestern Mexico: a cross-sectional study.

Background: Intestinal parasitism remains a public health challenge in northwestern Mexico even when a twice yearly single dose of albendazole (400 mg) is administered to schoolchildren. We aimed to determine the current prevalence of intestinal parasitic infections in schoolchildren of northwestern Mexico.

Methods: The Faust and Kato Katz techniques were used to detect and identify the intestinal parasite species.

Changes in serum zinc levels associated with giardiasis and dietary zinc intake in mice.

The association of giardiasis with the malabsorption of zinc remains controversial. This study investigated changes in serum zinc levels in Giardia-infected mice subjected to different dietary zinc regimens. Thirty-five mice (strain C(3)H/H(e)J) were randomly categorized into two groups.
