Nitric oxide (NO), the most potent natural vasorelaxant, has close relation to cardiovascular physiology, inspite of its complex chemistry; it is a signal-transducing radical. Aspects of NO biology critical to gastrointestinal health and, consequently, nutritional status are increasingly being recognized. Cross-talk between NO and micronutrients within and outside the gastrointestinal system affects the establishment or progression of several diseases with pressing medical needs. Some studies imply that NO has cytotoxic properties and is the genesis of numerous diseases and degenerative states, whereas other reports suggest that NO prevents injurious conditions from developing and promotes events which return tissue to homeostasis. NO or related species have been implicated in the regulation of many genes that participate in many diverse biological functions including programmed cell death or apoptosis. Along with cell apoptotic function, it also plays several roles in others parts of the body. In this review we are describing a gestalt on NO, which includes the various synthetic approaches, isoforms of NOS & its related aspects, multifactorial biological applications, its...

Nanocapsule consists of a thin membrane surrounding a core (Liquid, solid) with their size ranging from 10nm to 1000 nm. Nanocapsules are submicroscopic colloidal drug carrier systems composed of an oily or an aqueous core surrounded by a thin polymer membrane. The membrane may be composed of natural or synthetic polymers. Two technologies can be used to obtain such Nanocapsules: the interfacial polymerization of a monomer or the interfacial nano deposition of a preformed polymer. The nanometric size of Nanocapsule can be interesting for many applications like cosmetics, perfumes or pharmaceutical industries. This article is an extended review of these Nanocapsule technologies and their applications for the treatment of various diseases. The Nanocapsule is used in various fields for drug delivery in case of tumors, as a Nanocapsule Bandages to Fight Infection, as a liposomal Nanocapsule in Food Science and Agriculture, in delivering radio therapy and as a self healing...

Asavarishta is a very popular dosage form in ayurvedic medicines. It is a unique liquid dosage form that contains self generated alcohol, often referred as medicated wine. This self generated alcohol is produced by method of fermentation. Asavarishtas are manufactured by industries in batch size of thousand liters. Larger batch sizes of process specific products for high technology are the need of the time. The large scale industrial fermentation must produce high yields of product at least possible expenses and the recovery of product must be more. Thus the research is required to adapt the fermentation to existing types of fermentation equipment and to increase the yield of product. As self generated alcohol content should not exceed 11% v/v the fermentation process should be at a controlled rate and should be monitored precisely. Many times contamination by microorganisms during process of fermentation takes place if proper care is not taken during fermentation which is hazardous to product. Incubation time required for fermentation depends on temperature of environment. The temperature...

Kidney stone formation is a complex that results from a succession of several physicochemical events including supersaturation, nucleation, growth, aggregation and retention within the kidneys. Urinary stones affect 10-12 % of the population in industrialized countries. There are only a few geographical areas in which stone disease is rare e.g. Germany and in the coastal areas of Japan. So in the present review aims to give data highlighting the present trends in research of medicinal plants accredited with antiurolithiatic activity. This article may help investigators to identify lead compounds or herbal products responsible for urolithiatic activity....
