Medicinal plants form the backbone of traditional system of medicine in India. Biotechnological and Pharmacological studies have acknowledged the value of medicinal plants as potential source of bioactive compounds. Phytochemicals from medicinal plants serve as lead compounds in drug discovery and design. Medicinal plants are rich source of novel drugs that forms the ingredients in traditional systems of medicine, modern medicines, nutraceuticals, food supplements, folk medicines, pharmaceutical intermediates, bioactive principles and lead compounds in synthetic drugs. Aloe is a genus containing about four hundred species of flowering succulent plants belonging to Liliaceae family. Aloe vera is as old as civilization and through history it has been used as a popular folk medicine. It is present in the arid regions of India. Aloe vera has valuable medicinal properties and is commercially used in pharmaceuticals, cosmetics and food industries. Since ancient time Aloe vera L. are using in many herbal preparations. The Aloe vera plant contains the important antioxidant components such as vitamins (A, C and E), B (thiamine), niacin, B2...

, 3-Benzodioxole ring system present in various naturally occurring molecules. Various synthetic molecules having 1, 3-Benzodioxole ring system have shown various biological activities. Stiripentol and Antiepilepserine are recently developed antiepileptic drugs which contain 1, 3-Benzodioxle rings system in core moiety. In the present work I have focused on the anticonvulsant activity of 1, 3-Benzodioxole ring system based...

Biofilms are multicellular communities of bacteria. The ability to form biofilm is a universal attribute of bacteria and as bacteria can form biofilm in medical, industrial and environmental settings, it impacts human lives in many different ways. Bacteria undergo profound physiologic, morphologic and genetic changes as the transit from planktonic (free swimming, non-biofilm) form to surface attached biofilms. As bacteria in biofilm exhibit enhanced resistance to antibiotics and clearance by the host immune system, biofilm has been an intensely researched area for microbiologists, immunologists and pharmaceutical scientists alike. This review focuses on current knowledge on biofilm science, clinical relevance and virulence of biofilm, host response to it and therapeutic options to eradicate...

With the advent of newer technologies, in expert opinions, nanobiotechnology is expected to revolutionize or at least significantly improve the pharmaceutical and life science market within the next 15 years. The problem associated with reproducibility prevailed, a need for an economical polymer is experienced by all the researchers so as to repeat and check the reproducibility of systems. To meet all these requirements, Gelatin comes in front as the best alternate. Gelatin (or gelatin, from Latin: gelatus = stiff, frozen) is a translucent, colorless, brittle (when dry), flavorless solid, derived from collagen obtained from various animal by-products. It is commonly used as a gelling agent in food, pharmaceuticals, photography, and cosmetic manufacturing. Substances containing gelatin or functioning in a similar way are called gelatinous. Gelatin is an irreversibly hydrolyzed form of collagen. Gelatin being biodegradable in nature is a polymer of choice for the delivery of various proteins and peptides, can be an efficient and safe vaccine adjuvant,can be used forin vitro delivery of immunogenic CpG oligonucleotides, can be...

The icaADBC gene was first identified in Staphylococcus epidermidis, and is also present in Staphylococcus aureus and other Staphylococcal species. PIA is produced by the gene products encoded by the icaADBC operon. Asymptomatically colonized patients and health care workers are the major sources of MRSA in the hospital environment. MRSA-infected patients in burns units are particularly problematic because the big surface area of denuded skin can produce a large inoculum of organisms that can be easily transmitted to other patients via the hands of health care workers. Extensive skin lesions also result in heavy shedders of MRSA. Clinical isolates of Staphylococcus aureus can express the icaADBC-encoded polysaccharide intercellular adhesin/poly-N–acetylglucosamine (PIA/ PNAG). The icaADBC dependent and independent pathways will be stimulated using different chemicals and level of biofilm formation as well as PIA/PNAG level will be assayed. Besides, proteomics and transcriptomics analysis will be performed to get insights in the interaction of various factors of the pathways involved in the biofilm formation in wild type as well as mutant strains. The biofilm development...
