AIM To investigate the prevalence of human papillomavirus in transitional cell carcinoma of the urinary bladder in South Africa. METHODS Ninety-one archival samples of bladder transitional cell carcinoma were subjected to polymerase chain reaction (PCR) and non-isotopic in situ hybridisation (NISH) for the detection of human papillomavirus 6, 11, 16, 18,(More)
Kaposi sarcoma-associated herpesvirus/human herpesvirus 8 (KSHV/HHV-8) has been implicated in the etiopathogenesis of multiple myeloma. Although the association is biologically plausible and attractive, conflicting data have been reported, including evidence against the involvement of KSHV in the pathogenesis of the disease. The purpose of this study was to(More)
Recently, robotics has been seen as a key solution to improve the quality of life of amputees. In order to create smarter robotic prosthetic devices to be used in an everyday context, one must be able to interface them seamlessly with the end-user in an inexpensive, yet reliable way. In this paper, we are looking at guiding a robotic device by detecting(More)
Forty-eight periapical lesions were induced in the mandible of dogs. Subsequently, the dogs were given a single intramuscular injection of either benzylpenicillin, erythromycin, lincomycin or clindamycin. The antibiotic concentration in serum and exudate from the periapical lesions was measured. The highest concentration of benzylpenicillin in serum (4.3(More)
Robotic assistive devices enhance the autonomy of individuals living with physical disabilities in their day-to-day life. Although the first priority for such devices is safety, they must also be intuitive and efficient from an engineering point of view in order to be adopted by a broad range of users. This is especially true for assistive robotic arms, as(More)
In the realm of surface electromyography (sEMG) gesture recognition, deep learning algorithms are seldom employed. This is due in part to the large quantity of data required for them to train on. Consequently, it would be prohibitively time consuming for a single user to generate a sufficient amount of data for training such algorithms. In this paper, two(More)
In recent years, gesture-based interfaces have been explored in order to control robots in non-traditional ways. These require the use of systems that are able to track human body movements in 3D space. Deploying Mo-cap or camera systems to perform this tracking tend to be costly, intrusive, or require a clear line of sight, making them ill-adapted for(More)
The exposure of dental personnel to chloroform in root-filling procedures was evaluated. Four different root filling procedures were studied. In all the procedures studied, guttapercha was used as the root-filling material and chloroform or sealers containing chloroform were used. Ten teeth in each group were root-filled. In the first group, chloroform and(More)
