A phyllospheric bacterial culture, previously reported to partially replace nitrogen fertilizer (B. R. Patti and A. K. Chandra, Plant Soil 61:419-427, 1981) was found contain a fluorescent pseudomonas which identified as Pseudomonas putida Corynebacterium sp. The P. isolate produce an extracellular cutinase when grown in medium containing cutin, the polyester structural component of plant cuticle. grew on nitrogen-free but could not under any induction conditions tested, whereas grow medium....

Urothelial cancer of the renal pelvis (CRP) is predominantly associated with cigarette smoking. However, molecular pathogenesis initiation and progression smoke (CS)-induced CRP unknown. Majority high grade stage at presentation has a recurrence rate even after surgery. Earlier we reported that prolonged treatment (24 weeks) guinea pig model p-benzoquinone (p-BQ), product CS in vivo, produced carcinoma situ pelvis, noninvasive cancer. Since known to induce invasive cancer, investigated...

According to WHO classification system, non-invasive urothelial carcinoma represents in situ (CIS) and dysplasia. Dysplastic urothelium often progresses CIS that further advances (UC). The strongest risk factor for UC is cigarette smoking. However, the pathogenesis of smoke (CS)-induced poorly understood. Earlier we had shown p-benzoquinone (p-BQ), a major toxic quinone derived from p-benzosemiquinone CS vivo, causative various CS-induced diseases. Here, using guinea pig model showed...

Abstract Wetlands, refer to the confluence with regards land and water having a rich biological diversity multiple purpose. As per Ramsar Convention, framed in August 2002, East Kolkata Wetlands have been considered be of global significance. Although inappropriate supervision these wetlands, has led gradual deterioration this wetland. In present study, soil sample was collected from reclaimed agricultural wetlands Chowbaga area, areas coordinates 22.5296°N, 88.4207°E. The predominant or...

We consider a purchase inventory problem where both demand and supply have been taken to be random. Several possible ways of deriving the optimum order quantity based on distribution total cost proposed. Expressions for that minimizes mode or exceedance probability this worked out some particular distributions.
