Undernourished children exhibit impaired development of their gut microbiota. Transplanting microbiota from 6- and 18-month-old healthy or undernourished Malawian donors into young germ-free mice that were fed a diet revealed immature infants transmit growth phenotypes. The representation several age-discriminatory taxa in recipient animals correlated with lean body mass gain; liver, muscle, brain metabolism; bone morphology. Mice cohoused shortly after receiving severely stunted underweight...

Abstract Growth faltering in children (low length for age or low weight length) during the first 1,000 days of life (from conception to 2 years age) influences short-term and long-term health survival 1,2 . Interventions such as nutritional supplementation pregnancy postnatal period could help prevent growth faltering, but programmatic action has been insufficient eliminate high burden stunting wasting low- middle-income countries. Identification windows population subgroups on which focus...

The WHO Model List of Essential Medicines (EML) prioritizes medicines that have significant global public health value. EML can also deliver important messages on appropriate medicine use. Since 2017, in response to the growing challenge antimicrobial resistance, antibiotics were reviewed and categorized into three groups: Access, Watch Reserve, leading a new categorization called AWaRe. These categories developed taking account impact different classes implications for their 2023 AWaRe...

It is plausible that one of the key biological pathways through which Kangaroo mother care (KMC) improves health outcomes in LBW infants by enhancing human milk intake and quality. This hypothesis needs to be tested. To estimate effect promotion support KMC compared control during neonatal period on components. We randomized 550 (1500-2250 grams) intervention arm with for continuous skin-to-skin contact exclusive breastfeeding home visits or no such (control) period. All received routine...

The activity of the human immunodeficiency virus (HIV) protease is essential for processing gag-pol precursor proteins and maturation infectious virions. We have prepared a peptidomimetic inhibitor, U-75875, that inhibited HIV-1 protein in an essentially irreversible manner. Noninfectious particles produced presence drug contained gag precursors were morphologically immature. In peripheral blood mononuclear cells continuous cell line, U-75875 completely blocked HIV replication; latter case,...

Human immunodeficiency virus (HIV) infects human cells by binding to surface CD4 molecules and directly fusing with the cell membrane. Although mouse expressing bind HIV, they do not become infected, apparently because of a block in membrane fusion. To study this problem, we constructed recombinant vaccinia that can infect promote transient expression full-length mammalian cells. This virus, together another encoding biologically active HIV envelope glycoprotein gp160, allowed us...
