To investigate the dynamics and relative drivers of cellulose degradation during litter decomposition, a field experiment was conducted in three individual ecosystems (i.e., forest floor, stream, and riparian zone) of an alpine forest meta-ecosystem on the eastern Tibetan Plateau. Four litter species (i.e., willow: Salix paraplesia, azalea: Rhododendron lapponicum, cypress: Sabina saltuaria, an...
Particulate organic matter (POM) processing is an important driver of aquatic ecosystem productivity that is sensitive to nutrient enrichment and.drives ecosystem carbon (C) loss. Although studies of single concentrations of nitrogen (N) or phosphorus (P) have shown effects at relatively low concentrations, responses of litter breakdown rates along gradients of low-to-moderate N and P concentra...
The objective of this study was to evaluate the free radical scavenging potential and high performance thin layer chromatography (HPTLC) fingerprinting of Indigofera tinctoria (I. tinctoria). Phytochemical analysis was carried out using standard methods, and free radical scavenging activity of the plant was determined using 2,2-diphenyl-1-picrylhydrazy (DPPH), nitric oxide (NO) and superoxide a...
آرتریت روماتوئید rheumatoid arthritis,(ra) یک بیماری خود ایمن است که یکی از معیارهای تشخیصی آن وجود فاکتور روماتوئید ( rheumatoid factor,rf ) در سرم بیماران می باشد. مطالعات نشان داده اند که بین بیماران آرتریت روماتوئید rf+ و rf- از نظر تظاهرات بافت شناسی ( histologic ) اختلافاتی وجود دارد. در این مطالعه میزان (crp) c-reactive protein و ایزوتیپهای iga rf و igm rf در 45 بیمار مبتلا به ra مورد سن...

Parts of this plant are used in treatment of different conditions in traditional medicine. The plant is also used in other parts of world such as Thailand for treatment of diabetes mellitus. The plant is evaluated for various pharmacological actio...
Invasive alien plants can compete with native plants for resources, and may ultimately decrease native plant diversity and/or abundance in invaded sites. This could have consequences for native mutualistic interactions, such as pollination. Although invasive plants often become highly connected in plant-pollinator interaction networks, in temperate climates they usually only flower for part of ...
