We report a case of intra-abdominal bleeding from a ruptured liver tumour and a subcapsular haematoma. The characteristic ‘watering-can’ appearance indicates a poor prognosis. This appearance is due to contrast extravasation from multiple torn surface vessels secondary to the liver capsule being stripped off by the expanding subcapsular haematoma. Although the initial aim should be to ‘save the...

Seed morph, abiotic conditions and time of germination can affect plant fitness, but few studies have tested their combined effects on plasticity of plant life history traits. Thus, we tested the hypothesis that seed morph, germination season and watering regime influence phenotypic expression of post-germination life history traits in the diaspore-heteromorphic cold desert winter annual/spring...

BACKGROUND Esophageal cancer is the most common carcinoma in Black South African men. A number of etiological factors have been associated with the high prevalence. OBJECTIVES The present study was undertaken to address social and environmental factors associated with the cancer in the African Black population of KwaZulu-Natal. CASE-CONTROL STUDIES AND STATISTICAL ANALYSIS: The total number o...

Market garden products can carry several types of microorganisms, and their consumption is the source of many cases of food poisoning. This work aimed to improve food safety in Benin. In characterizing strains of K. pneumoniae and fluorescent Pseudomonas spp. at the biochemical and molecular level, the target was to identify contaminated watering water and garden products sold during Cotonou in...

Global warming is projected to continue, leading to intense fluctuations in precipitation and heat waves and thereby affecting the productivity and the relevant biological processes of grassland ecosystems. Here, we determined the functional responses to warming and altered precipitation in both typical and desert steppes. The results showed that watering markedly increased the aboveground net ...

It is not currently well-understood how much xylem conductance is lost in maize plants during the day, if conductance is recovered during the night, or what soil water conditions are required for recovery to take place. To answer these questions we designed a greenhouse experiment whereby two genetically dissimilar maize genotypes were subjected to a level of water stress commonly experienced i...
