The role of cyclooxygenase-2 (COX-2) and inflammatory markers in the progress of Alport syndrome in Egyptian children.

Background: Chronic inflammation and its control are crucial to the responses of glomerular and renal tubular cells. This contributes to the pathogenic mechanisms and advancement of the disease in Alport syndrome. The study aimed to elucidate the role of cyclooxygenase-2, Interleukin 4, Plasminogen activating inhibitor 1, and Prostaglandin E2 in the development and course of Alport syndrome.

An efficient in vitro propagation protocol of cocoyam [Xanthosoma sagittifolium (L) Schott].

Sprouted corm sections of "South Dade" white cocoyam were potted and maintained in a greenhouse for 8 weeks. Shoot tips of 3-5 mm comprising the apical meristem with 4-6 leaf primordial, and approximately 0.5 mm of corm tissue at the base.

Exploring the importance of within-canopy spatial temperature variation on transpiration predictions.

Models seldom consider the effect of leaf-level biochemical acclimation to temperature when scaling forest water use. Therefore, the dependence of transpiration on temperature acclimation was investigated at the within-crown scale in climatically contrasting genotypes of Acer rubrum L., cv.

Growth temperature modulates the spatial variability of leaf morphology and chemical elements within crowns of climatically divergent Acer rubrum genotypes.

Our understanding of leaf acclimation in relation to temperature of fully grown or juvenile tree crowns is mainly based on research involving spatially uncontrolled growth temperature. In this study, we test the hypothesis that leaf morphology and chemical elements are modulated by within-crown growth temperature differences. We ask whether within-species variation can influence acclimation to elevated temperatures.
