Jaggery Sugar is an important medicinal product being prepared traditionally by concentrating the sugarcane juice at constant boiling and used as major constituents in ayurvedic fermenetd formulations. Fermentation itself induced certain chemical changes in formulations as well in Jaggery due to increase in acidic concentration of formulation. A qualitative comparison of RP-HPLC-DAD chromatograph of both fermented and non fermented Jaggery was made to understand the chemical changes in it. HPLC-DAD analysis of both the fermented and non ¿ fermented Jaggery revealed a qualitative decrease in flavonoid -O- glycoside concentration in fermented Jaggery as compare to the non ¿ fermented Jaggery. Flavonoid -C- glycoside were the major one in both fermented and non ¿ fermented Jaggery. Since flavonoid -C- glycosides are the major ones therefore the biological activities may be attributed to flavonoid -C- glycosides. The presence of gallic acid, ellagic acid and 5-HMF were also noted. This works highlights the importance of use of Jaggery in most of the Ayurvedic formulations.

Nanofiber drug delivery systems are capable to improve therapeutic efficacy, diminish toxicity, and can be designed to control and prolong drug release by regulate the degradation rate of the polymer.The concept of multilayer nanofibrous patch will localize the formulation at a particular region of the body, thereby improving bioavailability of the drugs with low bioavailability. The increased contact time and localization of the drug added advantage of this approach would be increase in bioavailability as well as reduction in frequency of administration. The encapsulation of Acyclovir with polymeric nanopatch could be an effective approach for producing a sustained release of the drug making it suitable for oral or other routes of administration such as intrapulmonary or intravitreal.developed multilayered nanofiber formulation was found to show controlled delivery of antiviral drug (Acyclovir). The formulation showed pH-responsive drug release at small intestine and colon system. In pharmacokinetic studies in rats, developed formulation exerted sustain release with improved pharmacokinetic profile.

Stroke has become one of the leading cause of mortality and long term disability in developing world. The cause of disability is multi factorial in its determination. Many advances have been made in stroke prevention and management, however, stroke continues to be a prevalent and burdensome condition, particularly among the elderly, but now gaining momentum in occurrence among the young too. Stroke is one of the most common life threatening neurological disease and is one of the main cause of long term disability in adults worldwide. Over years, stroke has become major health problem in India. The prevalence of stroke in India was estimated as 203 per 100,000 populations above 20 years, amounting to a total of about 1 million cases. The effects of stroke are variable depending on location of the lesion as well as the size. The most typical symptom of stroke is hemiparesis or hemiplegia, which ranges from weakness to full paralysis of the body opposite to the side of the lesion, affecting the person¿s activities of daily living and community participation.Hence essential details of various domains of its multifaceted influence on life of people becomes crucial.

Surface method of irrigation is the oldest and most common method of irrigation. It consists of a broad class of irrigation methods in which water flows over the soil surface and distributed over the field by gravity flow with the intention that the applied water infiltrates into the soil. Surface irrigation, though looks very simple, is a very complex process due to spatial and temporal variations in soil infiltration and crop resistance which influence the movement of water over the field and thus the water distribution. Typically, there may be four phases during a surface irrigation event: (i) water advance in the field, (ii) wetting or ponding to supply desired amount of water, (iii) depletion of ponded water, and (iv) recession of water along the reach of the field.

Der Schlaganfall ist in den Entwicklungsländern zu einer der Hauptursachen für Sterblichkeit und langfristige Behinderungen geworden. Die Ursache für die Behinderung ist multifaktoriell bedingt. In der Schlaganfallprävention und -behandlung wurden viele Fortschritte erzielt, dennoch ist der Schlaganfall nach wie vor eine weit verbreitete und belastende Erkrankung, insbesondere bei älteren Menschen, aber auch bei jungen Menschen tritt er immer häufiger auf. Der Schlaganfall ist eine der häufigsten lebensbedrohlichen neurologischen Erkrankungen und eine der Hauptursachen für langfristige Behinderungen bei Erwachsenen weltweit. Im Laufe der Jahre hat sich der Schlaganfall in Indien zu einem großen Gesundheitsproblem entwickelt. Die Prävalenz des Schlaganfalls in Indien wurde auf 203 pro 100.000 Einwohner über 20 Jahre geschätzt, was einer Gesamtzahl von etwa 1 Million Fällen entspricht. Die Auswirkungen des Schlaganfalls sind je nach Ort der Läsion und Größe unterschiedlich. Das typischste Symptom des Schlaganfalls ist die Hemiparese oder Halbseitenlähmung, die von Schwäche bis zur vollständigen Lähmung des Körpers auf der der Läsion gegenüberliegenden Seite reicht und die Aktivitäten des täglichen Lebens und die Teilhabe an der Gesellschaft beeinträchtigt.
