(Akamai University, 2012)The rapid advancement in Information and Communication Technology (ICT) has undoubtedly influenced positive changes in carrying out administrative functions in government institutions. The ICT adoption rate in Africa is ... -
Comparing community structure on shells of the abalone Haliotis midae and adjacent rock: implications for biodiversity
(Springer Verlag, 2013)This paper concerns the effects on biodiversity of depletion 24 of the South African abalone Haliotis midae, which is a long-lived species with a large corrugated shell that provides a habitat for diverse benthic organisms. ... -
Using wearable sensors for remote healthcare monitoring system
(Scientific Research Publishing, 2011)Recent technological advances in wireless communications and wireless sensor networks have enabled the design of low-cost, intelligent, tiny, and lightweight medical sensor nodes that can be strategically placed on human ... -
Evaluating SMS parsing using automated testing software
(Institute of Electrical and Electronics Engineers (IEEE) Inc., 2012)Mobile phones are ubiquitous with millions of users acquiring them every day for personal, business and social usage or communication. Its enormous pervasiveness has created a great advantage for its use as a technological ... -
The Microbial Aetiology of Periodontal Diseases
(InTech, 2012)Introduction: The study of the aetiology of periodontal diseases has continued for decades with much progress shown in the last two decades. Having moved through periods of “whole” plaque (with emphasis on mass) being ... -
Strengths and limitations of different Chromogenic Media for the identification of Candida species
(Scientific & Academic Publishing, 2012)The treatment of invasive candidiasis and other Candida infections with the appropriate antifungal agent is assisted by the identification of Candida isolates to the species level. Rapid and accurate methods of differentiation ... -
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, ... -
Oral colonization of Gram-negative anaerobes as a risk factor for preterm birth
(Landes Bioscience, 2011)Preterm birth significantly impacts on neonatal morbidity and mortality and is apparently increasing worldwide. Several studies have attempted to define a causative role for periodontal disease in adverse pregnancy ... -
An in-vitro analysis of the antimicrobial efficacy of herbal toothpastes on selected primary plaque colonizers
(iMD Publishers, 2011)Plaque associated oral disease affects a considerable portion of the population and is considered one of the major causes of tooth loss. In most cases toothbrushing only removes a limited amount of dental plaque and other ... -
Examination of maternal gingival crevicular fluid for the presence of selected periodontopathogens implicated in the pre-term delivery of low birthweight infants
(Landes Bioscience, 2010)Background: Reports show that more than 20 million infants world-wide are born prematurely with 95% of all pre-term births occurring in developing countries. Oral colonization of Gram-negative anaerobes has been implicated ... -
The association between gender and tooth loss in a small rural population of South Africa
(Science Publishing Group, 2013)Periodontal disease, which attacks the gums and supporting structures of the tooth, is one of the major causes of tooth loss in adults. Few studies on general well-being have compared the differences in oral health between ... -
Risk factors of preterm delivery of low birth weight (plbw) in an African population
(Academic Journals, 2010)More than 20 million infants in the world (15.5% of all births) are born with low birth weight. Ninety-five percent of them are in developing countries. The objective of this study was to examine different factors which ... -
Is human Immunodeficiency Virus (HIV) stage an independent risk factor for altering the periodontal status of HIV-positive patients? A South African study
(BioMed Central, 2013)Background: The immunosuppresion in HIV patients makes them highly susceptible to microbial infections. The aim of the study was to establish whether HIV stage (as depicted by CD4+ T lymphocyte counts) could independently ... -
Metronidazole in the Prophylaxis and treatment of Anaerobic Infection
(Health and Medical Publishing Group, 1978)The influence of prophylactic metronidazole on vaginal carriage rates of anaerobes and the development of postoperative anaerobic infection was studied in 104 women who underwent abdominal hysterectomy. Metronidazole ... -
A Novel Severe Acute Respiratory Syndrome Coronavirus Protein, U274, is transported to the Cell Surface and undergoes Endocytosis
(American Society for Microbiology, 2004)The severe acute respiratory syndrome coronavirus (SARS-CoV) genome contains open reading frames (ORFs) that encode for several genes that are homologous to proteins found in all known coronaviruses. These are the replicase ... -
Overexpression of 7a, a Protein Specifically Encoded by the Severe Acute Respiratory Syndrome Coronavirus, Induces Apoptosis via a Caspase-Dependent Pathway
(American Society for Microbiology, 2004)Besides genes that are homologous to proteins found in other coronaviruses, the severe acute respiratory syndrome coronavirus genome also contains nine other potential open reading frames. Previously, we have characterized ... -
The role of Severe Acute Respiratory Syndrome (SARS)-Coronavirus Accessory Proteins in Virus Pathogenesis
