Lab-on-a-chip (LOC), a scaled down microfluidic device for carrying out laboratory operations outside the scope of standard laboratories is a rather appealing development in the field of science and technology for the whole laboratory has been reduced to a small chip capable of carrying out various functions. Keeping to its word, micro, miniaturized volume samples and reagents has ebbed the time taken to analyze a reaction apart from the distinctive behaviour of liquids at the nano scale which has permitted substantial control of molecular interactions and concentrations. Also, amount of chemical waste and the cost of reagents has been minimised very drastically. This review article thus focuses on the importance of LOCs in the field of health care apart from its progress and incorporation in biotechnological researches over the past...

Kamdhenu or Indian cow (Bos indicus) is worshipped as sacred animal by Hindus. The reason for worshipping is the tremendous therapeutic values of cow derived products like cow milk, cow milk curd, cow butter (ghee), cow urine, cow dung and a combination formulation Panchgavya. The use of these products has been well defined in ancient Ayurvedic texts like Charak samhita, Shushruta samhita, Brahad-Wagbhatt etc. Cow ghee showed anticancer and hepatoprotective potential by altering the enzymatic activities whereas cow urine acts by an unknown mechanism. Analgesic activity is attributed to presence of steroidal moieties and volatile fatty components in it. Antioxidants isolated from cow urine are responsible for antidiabetic, immunomodulatory, antiepileptic, antibacterial, antifungal and antimicrobial activities. Cow ghee contains a number of saturated and unsaturated fatty acids that plays active roles in production of inflammatory mediators and wound healing processes. This study is to gather the scientific research findings to support the traditional uses of cow derived products and to create research interest in...

In recent years heterocyclic compounds analogues and derivatives have attracted wide attention due to their useful biological and pharmacological properties. Benzothiazole is a privileged bicyclic ring system with diverse applications. The small and simple benzothiazole nucleus is present in compounds involved in research aimed at evaluating new products that possess biological activities, such as anticancer, antimicrobial, and antidiabetic, anticonvulsant, anti-inflammatory, antiviral, ant tubercular activities. These compounds have special significance in the field of medicinal chemistry due to their remarkable pharmacological potentialities. This review is mainly focus on the research work reported in the recent scientific literature on different biological activities of benzothiazole...

Transdermal drug delivery systems (TDDS) offers a route that by-passes the gut and hence they are more convenient. They are also non-invasive and safer than the other alternatives. The transdermal or the adhesive patches are used to deliver a specific quantity of drug in a controlled release manner through skin for over a long period of time. There are many types of patches like the matrix, membrane, reservoir, micro reservoir etc. These patches have been in use to deliver many classes of drugs like analgesics, anti-pyretics, anti-diuretics, anti-asthmatics, etc. There are many anti-asthmatic products that are available in the form of transdermal patches internationally like the tulobuterol, salbutamol, ketotifen, etc., but the question is about their usage and availability. The primary aim of this review is to understand the availability of evidences for and against the use of TDDS for asthma. Most studies, both in vivo and in vitro, and both as add-on and as a monotherapy have yielded positive...
