Heterogeneity in the Helicobacter pylori vacA and cagA genes: association with gastroduodenal disease in South Africa?
In this study, the vacA s1 genotype, and fragment length of the 3' region of cagA identified isolates associated with significant clinical disease. The vacA s1bm1 genotype seems to be strongly associated with gastric cancer.
Impaired wound healing is characterized by pro-inflammatory MMP-2 and MMP-7. Serum and effluent concentrations of MMP-2, MMP-3, and MMP-7 can effectively predict the outcome of traumatic war wounds and can potentially provide decision-supportive, objective evidence for the timing of wound closure.
