The scientists at ALMPG Institute of Basic Medical Sciences, University of Madras, Chennai, India evaluated a combination of spices (Piper nigrum Linn., P. longum Linn. and Zingiber officinale Rosc.), herbs (Cyperus rotundus Linn. and Plumbago zeylanica Linn.) and salts make up Amrita Bindu for its possible antioxidant activity. The study was focused to evaluate the antioxidant property of indi...

In a recent work, a new numerical method (the lifespan method) has been introduced to study the critical properties of epidemic processes on complex networks [M. Boguñá, C. Castellano, and R. Pastor-Satorras, Phys. Rev. Lett. 111, 068701 (2013)]. Here, we present a detailed analysis of the viability of this method for the study of the critical properties of generic absorbing-state phase transit...

Natural products have long served as both a source and inspiration for pharmaceuticals. Modifying the structure of a natural product often improves the biological activity of the compound. Metabolic engineering strategies to ferment "unnatural" products have been enormously successful in microbial organisms. However, despite the importance of plant derived natural products, metabolic engineerin...

Changing in the production of anticancer drugs (vinblastine and vincristine) Catharanthus roseus (L.) G. Don by potassium ascorbic acid treatments | Neda Sahi, Akbar Mostajeran, Mustafa Ghanadian Agricultural Journals

Melioribacter roseus, a representative of recently proposed Ignavibacteriae phylum, is a metabolically versatile thermophilic bacterium, inhabiting subsurface biosphere of the West-Siberian megabasin and capable of growing on various substrates and electron acceptors. Genomic analysis followed by inhibitor studies and membrane potential measurements of aerobically grown M. roseus cells revealed...

Intact sperm cells of Plumbago zeylanica were released from mature pollen grains near anthesis using osmotic shock with 20% sucrose. Sperm cell yields of up to 75% can be attained by differential centrifugation using a clinical centrifuge with concentrations of up to 8.8 x 10(6) cells/milliliter. Such ;gametoplasts' remain intact for up to 24 hours according to Evan's blue exclusion and can be ...

Northern wild rice is of great dietary and cultural importance to the Native American population in Upper Peninsula Michigan. Millions tons mine tailings were discharged into Lake Superior other inland lakes during copper mining boom early 20th century this area. This includes L’Anse Bay, located within Keweenaw Bay Indian Community (KBIC) reservation. Since restoration being encouraged by KBIC...

catharantus-roseus is a medicinal and ornamental plant with growing attention toward its economical value. to determine cell viability based on trypan blue  and  mtt assay, cell suspension from callus of catharantus-roseus were treated with different concentrations of cadmium-nitratee for 1, 3 and 6 days.  also cell suspension was used to investigate the cell morphology for a period of 3 days u...

Catharanthus roseus (L.).G. Don, a highly valued medicinal plant suffers from a serious disease. A survey on the symptom and severity of the leaf blight of C. roseus was performed in the nurseries of the Institute of Forestry and Environmental Sciences (IFESCU), Bangladesh Council of Industrial Research (BCSIR) and Bangladesh Forest Research Institute (BFRI), Bangladesh. An observation was also...
