Evaluation of the effect of an extract of Sphingomonas xenophaga present in a Thermal Spring Water in the management of sensitive skin associated with cutaneous vascular disorder. [PDF]

Int J Cosmet Sci
Inhibition of the kallikrein‐kinin system is a potential approach to the dermocosmetic treatment of skin disorders associated with redness. We showed that a cream formulation with a Sphingomonas ferment extract inhibiting this system was effective in improving vascular disorder after repeated application in female volunteers with sensitive and reactive

Impact of Seasonal Variation on Antioxidant, Enzyme Inhibitory, and Anti-Inflammatory Potentials of Cistus creticus Leaf Extracts. [PDF]

ChemistryOpen
The phytochemical profile and biological activities of Cistus creticus leaf ethanolic extracts show strong seasonal variation. Spring extracts contain the highest phenolic levels with potent antioxidant and anti‐inflammatory effects, while summer extracts are richest in flavonoids and exhibit the greatest sun protection factor value and enzyme ...

Mapping the density of giant trees in the Amazon. [PDF]

New Phytol
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Biomass estimation of rangelands in the Eastern Highlands by remote sensing indices

African and Mediterranean Agricultural Journal - Al Awamia, 2022
The rangelands of the High plateau of eastern Morocco constitute an important supplement to the feeding of sheep and goats. Estimating phytomass production from these rangelands during the growing season is useful for managers of pastoral areas.

Influence de l'exploitation sur un pâturage à Andropogon gayanus Kunth. var. tridentatus

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1980
La biomasse élevée d'un pâturage sahélien non exploité à Andropogon gayanus pourrait donner une fausse impression de sa capacité de charge, car l'exploitation de cette espèce doit être prudente et limitée sous les conditions sahéliennes.
