Anthropometric characteristics and nutritional status of older adults in the Lake Victoria Basin of East Africa: region, sex, and age differences
(2015)Background: Malnutrition, either as undernutrition or overnutrition, leads to detrimental alterations in body composition. The objective of this study was to investigate selected anthropometric measurements, and the ... -
Antimicrobial Activity and Characteristics of Bacteriocin Producing Bacillus subtilis against Mastitis Pathogens
(American Journal of Food Science and Technology, 2021)The use of drugs and antibiotics has increased the resistance of pathogenic bacteria in both animals and humans. This has been a significant problem and therefore triggers the investigation of novel antimicrobial ... -
Antimicrobial Activity of Root Bark Extracts of Rhus natalensisa and Rhus ruspolii
(Scientific & Academic Publishing, 2019-08)Bacteria and fungi are frequent causes of serious opportunistic infections worldwide. Several effective antibiotic drugs are in the market. However, drug-resistance, side effects and cost of such antibiotics limits their ... -
Antimicrobial Compounds from Terminalia brownii against Sweet Potato Pathogens
(Bentham Science Publishers, 2011)Phytochemical evaluation of Terminalia brownii extracts led to the isolation of five compounds namely - sitosterol, stigmasterol, monogynol A, betulinic acid and arjungenin. Their structures were established by spectroscopic ... -

(WebmedCentral, 2010-09)The study describes the antibacterial and antifungal effects of both CH2Cl2 and MeOH crude extracts, collected fractions and pure isolates of Conzya floribunda. The antimicrobial activity tests were carried out using agar ... -
Antimycobacterial Activity, Cytotoxicity and Phytochemical Screening of Organic Extracts of Commiphora Africana Stem Bark from Kenya
(East African Scholars Publisher, 2020-04)Tuberculosis (TB) is a communicable disease that kills approximately three million people annually. Efforts to treat the disease have been made difficult due to the development of drug-resistant strains and co-infection ... -
Antiplasmodial activity, in vivo pharmacokinetics and anti-malarial efficacy evaluation of hydroxypyridinone..
(2015)Background: During the erythrocytic stage in humans, malaria parasites digest haemoglobin of the host cell, and the toxic haem moiety crystallizes into haemozoin. Chloroquine acts by forming toxic complexes with haem ... -
Antiplasmodial activity, in vivo pharmacokinetics and anti‑malarial efficacy evaluation of hydroxypyridinone hybrids in a mouse model
(2016)During the erythrocytic stage in humans, malaria parasites digest haemoglobin of the host cell, and the toxic haem moiety crystallizes into haemozoin. Chloroquine acts by forming toxic complexes with haem molecules and ... -
Antiplasmodial activity, in vivo pharmacokinetics and anti‑malarial efficacy evaluation of hydroxypyridinone hybrids in a mouse model
(Dambuza et al. Malar J, 2015)Background: During the erythrocytic stage in humans, malaria parasites digest haemoglobin of the host cell, and the toxic haem moiety crystallizes into haemozoin. Chloroquine acts by forming toxic complexes with haem ... -
Antiplasmodial Flavonoids from Erythrina sacleuxii
(Planta Med, 2006)The acetone extracts of the root bark and stem of Erythrina sacleuxii showed antiplasmodial activities against the chloroquine-sensitive (D6) and chloroquine-resistant (W2) strains of Plasmodium falciparum. Chromatographic ... -
