The regeneration niche has been little investigated in studies of community assembly and plant distribution. We examined adaptive associations between seedling traits and habitat specialization. Two habitat contrasts were investigated across several evolutionary lineages of angiosperms: species specialized to forest vs. open habitats and to dry vs. wet habitats. We also tested whether effects o...

OBJECTIVE To assess the effectiveness of sodium hyaluronate Eye Gel in Dry Eye Disease (DED) patients Methods: A Multi-center, Open-label, Uncontrolled clinical trial was conducted in different centers of Pakistan. Ten ophthalmologists conducted this study in which 250 diagnosed patients with dry eye disease were enrolled after obtaining a written informed consent. Ten patients were dropped out...

Proliferation of woody plants in grasslands and savannas since the 1800s has been widely documented. In the southwestern United States, increased abundance of honey mesquite (Prosopis glandulosa var. glandulosa) has been attributed to heavy grazing by livestock. Here, we test the hypothesis that P. glandulosa invasion of grasslands requires, first, reductions in herbaceous biomass and density s...

Drought tolerant plant genotypes are able to maintain stability and integrity of cellular membranes in unfavorable conditions, and to regenerate damaged membranes after stress cessation. The profiling of cellular glycerolipids during drought stress performed on model species such as Arabidopsis thaliana does not fully cover the picture of lipidome in monocots, including grasses. Herein, two clo...

The photosynthetic efficiency of C3 grasses declines with increasing temperature and C4 grasses are predicted to be advantaged at temperatures above 15 °C. We demonstrated an above-ground productivity difference in a commongarden experiment with Alloteropsis semialata and show that it is related more to differences in life-history than to photosynthesis. Frost caused leaf mortality in the C4 bu...

A total of sixteen patients with urethral stricture and/or perineal urinary fistulae (water-can perineum) complicating gonorrhoea were seen at the Special Treatment Clinic, University College Hospital, Ibadan, Nigeria. The patients were aged between 25 and 80 years, and the latent period between the time of original attack of gonococcal infection and the development of complications varied from...

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...

Climate change predicts harsher summer droughts for mid-latitudes in Europe. To enhance our understanding of the putative impacts on forest regeneration, we studied the response of oak seedlings (Quercus petraea) to water deficit. Potted seedlings originating from three locally sourced provenances were subjected to two successive drought periods during the first growing season each followed by ...
