We have previously identified and characterized the alkyl hydroperoxide reductase of Streptococcus mutans, which consists of two components, Nox-1 and AhpC. Deletion of both nox-1 and ahpC had no effect on the sensitivity of S. mutans to cumene hydroperoxide or H(2)O(2), implying that the existence of another antioxidant system(s) independent of the Nox-1-AhpC system compensates for the deficie...

Healthcare has been recognised as one of the most important areas for enterprise applications and services. Presently, information technologists and systems engineers all over the world are working towards achieving better efficiency and quality of service in various sectors of healthcare, such as telemedicine, hospital management, patient-care, and treatment.

The World Medical Association's Declaration of Helsinki offers guidelines to doctors engaged in biomedical research with human subjects. The fundamental distinction of the Declaration is between clinical research combined with professional care and non-clinical scientific research. If hospital patients are the experimental subjects, then the former research must be carried out by the patient's ...

Cell-to-cell transmission of protein aggregates is an emerging theme in neurodegenerative disease. Here, we analyze the dipeptide repeat (DPR) proteins that form neuronal inclusions in patients with hexanucleotide repeat expansion C9orf72, the most common known cause of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Sense and antisense transcripts of the (G4C2...
