In Vivo Antifungal Activity of South African Medicinal Plant Extracts against pathogens and Their Phytotoxicity Evaluation.

Smallholder farmers play a major role in crop production towards household food security, particularly in resource-poor communities. Maize is a common crop produced in smallholder farming and it is cultivated from seeds that has been stored and re-used for years. Spoilage of stored grains is a major challenge, which leads to yield loss and poor seed quality.

Identification and characterization of PAH-degrading endophytes isolated from plants growing around a sludge dam.

This study involved the isolation of bacteria endophytes with PAH-degrading ability from plants growing around a sludge dam. A total of 19 distinct isolates that were morphologically identified were isolated from 4 species of plant with a follow-up confirmatory identification using the molecular technique. Polymerase chain reaction (PCR) of the 16S rRNA gene with specific primers (16S-27F PCR and 16S-1491R PCR) was carried out.

Tongue protrusion as an indicator of vital burning.

In the forensic assessment of burned bodies, the question of whether the victim was exposed to the fire before or after death is of crucial importance. Several external signs have been used in the past to indicate heat exposure prior to the death of the victim but these did not include tongue protrusion. The internal signs of heat exposure are generally regarded as much more important than those observed externally.
