Abstract:
Validation is a important part of Analytical as well as Bio-Analytical Method. The procedures involved in checking data or programs for correctness, compliance with standards and conformance with the requirement specifications. It  is establishing documented evidence, which provides high degree assurance that a specific process will consistently produce a product meeting its predetermined specification and quality characteristics. Calibration is totally differ from Validation But it is an integral part of validation.

Abstract:
To build up an oral drug delivery system, it is essential to optimize both release rate of drug and residence time of system within gastrointestinal tract. In oral path difference in gastric physiology such as gastric pH and motility display variability on gastric residence time (GRT) and drug delivery actions. Several approaches are currently utilized in the prolongation of the GRT including hydrodynamic balance systems (HBS), swelling and expanding systems, polymeric bioadhesive systems, high-density systems, modified-shape systems and other delayed gastric emptying devices.One such approach is Floating Microspheres (Hollow Microspheres). Floating microspheres are gastro-retentive drug delivery systems based on non-effervescent approach. These microspheres are characteristically free flowing powders made of proteins or synthetic polymers, ideally having a size less than 200 micrometer. Gastro-retentive floating microspheres are low-density systems that have sufficient buoyancy to float over gastric contents and remain in stomach for prolonged period. The drug is released slowly at desired rate resulting in increased gastric retention with reduced fluctuations in plasma drug concentration. Floating microspheres improve patient compliance by decreasing dosing frequency and better therapeutic effect of short half-life drugs can be achieved. Floating microspheres are characterized by their micromeritic properties such as particle size, tapped density, compressibility index, true density and flow properties including angle of repose, scanning electron microscopy, in vitro floatability studies, in vitro drug release studies and stability studies etc.

ABSTRACT:
The oral delivery of drugs having narrow absorption window in the gastro-intestinal tract is limited by poor bioavailability with conventional dosage forms due to incomplete drug release and short residence time at the time of absorption. To provide controlled delivery of drugs novel drug delivery systems have been developed. Different systems have been developed to increase the gastric residence time viz. floating system, mucoadhesive, high density, expandable. Among all oral dosage forms, liquid orals are more prone to low bioavailability due to fast transit time from stomach to duodenum. Sustained/Controlled delivery can be achieved by decrease in the transit time of the dosage form. This can be augmented by an approach of liquid in-situ gelling system. These in-situ formulations are the drug delivery systems that are in sol form before administration in the body, but when administered, undergo gelation, in-situ, to form a gel. Formation of gel depends on various factors viz. temperature modulation, pH change, presence of ions, ultra-violet irradiation, from which drug releases in a sustained and controlled fashion. Different polymers which can be used for formation of in-situ gel include gellan gum, alginic acid, xyloglucan, pectin, chitosan, poly-caprolactone, poly-lactic acid, poly-lactic-co-glycolide. This article presents a detailed review of introduction, approaches to achieve in situ gelling system, polymers used, evaluation parameters, advantages of in situ gelling system.

Abstract
Aromatase and 17-ßHSD inhibitors are main target of pharmacological interest for the treatment of estrogen dependent cancers. Chalcones, Coumarins, Flavones, Isoflavones have been reported for such inhibition and are used for treatment of breast tumors. So in this topic, Flavone derivatives containing Imidathiadiazole, Thiadiazole, Triazole and benzimidazole hetrocycles synthesised by using simple laboratory reagents like 2-Hydroxy Acetophenone and 4-Hydroxy Benzaldehyde to convert chalcone leads to formation of Flavones by cyclazation using Microwave and followed by attachment of different hetrocycles to form Flavone derivatives and charactrarized by IR, ¹H NMR, ¹³C NMR spectroscopy and elemental analysis. These Flavone derivatives found to exhibit moderate to high inhibitory activity against Estrogen dependent cancers.

Abstract
The AIDS pandemic is one of the most disastrous health and development issue in our world today. Tissue culturing of medicinal plants is widely used to produce active compounds for herbal and pharmaceutical industries. Natural products provide a large reservoir for screening of anti-HIV agents with novel structure and anti-viral mechanism because of their structural diversity. This work reviews in vitro micro propagation techniques and gives examples of various commercially important medicinal plants. Advantages-To produce many copies in any time of the same plants then which may be used to produce plants with better flowers, odour’s, fruits or any other properties of the plants that is beneficial to the human beings. Conclusion- HIV is the most common untreated word wide disease in now a days and Plant tissue culture is most important technique for growing new plant species in proper aseptic condition which are useful for the cure of HIV.
