(AOSIS, 2018)BACKGROUND: Altered immune mechanisms play a critical role in the pathogenesis of non- Hodgkin’s lymphoma (NHL). HIV-1 (HIV) infection is associated with a state of excessive T-cell activation, which can lead to increased ... -
Bacterial morphotype grading for periodontal disease assessment
(Nature Publishing Group, 2017)BACKGROUND: Listgarten and Hellden (1978) used darkfield microscopy of wet mounts to differentiate between healthy and periodontally diseased sites in the mouth by expressing the different bacterial morphotypes observed ... -
BANA-positive plaque samples are associated with oral hygiene practices and not CD4+ T cell counts in HIV-positive patients
(Hindawi Publishing Corporation, 2012)Background. The “red complex” microorganisms, namely, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia are considered as potential pathogens causing HIV-associated periodontal diseases. Moreover, ... -
The beneficial role of anchomanes difformis in stz-induced reproductive dysfunction in male wistar rats
(Dove Medical Press, 2020)Progression of diabetes mellitus has increasingly led to several diabetic complications. Diabetes is one of the major factors implicated in male reproductive system damage. Recent approaches such as the use of medicinal ... -
Bibliometrics: tracking research impact by selecting the appropriate metrics
(Medknow Publications, 2016)Traditionally, the success of a researcher is assessed by the number of publications he or she publishes in peer-reviewed, indexed, high impact journals. This essential yardstick, often referred to as the impact of a ... -
Biodegradable ceramics consisting of hydroxyapatite for orthopaedic implants
(MDPI, 2017)This study aims to analyze hydroxyapatite (HAP) coatings enriched with Mg and Ti prepared by a magnetron sputtering technique on Ti6Al4V substrate. For preparation of the coatings, three magnetron targets (HAP, MgO and ... -
Biosensors as early warning detection systems for waterborne cryptosporidium
(IWA Publishing, 2023)Waterborne disease is a global health threat contributing to a high burden of diarrhoeal disease, and growing evidence indicates a prospective increase in incidence coinciding with the profound effects of climate change. ... -
Biosynthesis of silver nanoparticles using Bersama engleriana fruits extracts and their potential inhibitory effect on resistant bacteria
(MDPI, 2022)The absence of novel, safe, and effective bactericide is an urgent concern worldwide and remains a challenge in scientific communities. The unique proprieties of silver nanoparticles (SNPs) synthesized from plant extracts ... -
