Some biogenic amine like Histamine, cadaverine and putrescine have been confirmed as useful chemical indicators to estimate bacterial spoilage of foods, particularly fish and fish products, cheese, meat and fermented foods. Histamine is toxic at high intakes, while cadaverine and putrescine potentiate the effects of Histamine. Histamine has regulated level of 200 mg/kg (200 ppm). Basic principle involved in Biogenic amines biosensor is the action of diamine oxidase (DAO) that catalyzes the oxidative deamination of primary amines to the corresponding aldehydes, hydrogen peroxide and ammonia. Two different approaches for the histamine biosensor design were studied, i.e. the enzyme DAO was directly immobilized on the surface of the oxygen electrode membrane using glutaraldehyde or entrapped in a hydrogel film. In histamine biosensor consisting of diamine oxidase (DAO) and a conventional oxygen electrode transducer was developed and applied for the determination of standard histamine solutions. For immobilisation with glutaraldehyde, the enzyme was cross-linked with glutaraldehyde as a bifunctional reagent on the electrode surface. For entrapment, DAO was entrapped in a polymeric...

Arecanut seed has been used for medicinal properties more than 2000 years in South Asian countries. In fact, various pharmacological activities have been found in the arecanut seed extract or its constituents. Prevention of oxidative stress induced diseases is an urgent problem in all over the world. Traditional use of the plant for medicinal properties is to be documented for their possible use as future medicines or drugs. There is a need for identifying native natural plant sources to acquire to their recognized medicinal properties, which may widen them to use as new therapeutics for various diseases. In the present article, it has been described about usefulness of arecanut as an herbal drug and its therapeutics application...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women. PCOS varies from a mild menstrual disorder to severe disturbance of reproductive and metabolic functions. Statins, 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase inhibitors with intrinsic antioxidant properties, exert profound and broad-reaching effects on various types of tissues. By blocking an early step of the mevalonate pathway, statins inhibit proliferation of several cell types including vascular smooth muscles, hepatocytes, and several neoplastic cell lines. The pleiotropic effects of statins may be due to inhibition of cholesterol synthesis. Some common treatments lifestyle changes, insulin-sensitizing...

Guillain-Barré syndrome is a rare but important disease that can lead to life threatening respiratory failure. This review summarises the verified consideration of Guillain-Barré syndrome (GBS) which are thought to be caused by direct autoimmune attack on peripheral nerves. Aim- Nerve conduction study helps differentiate the heterogeneous subtypes of GBS. Patients exhibit a progressive paralysis that reaches a plateau phase. Treatment and Result- Treatment with both intravenous immunoglobulin and plasma exchange reduces the time taken for recovery to occur, although mortality remains around 8%, with about 20% of patients remaining disabled. Though no significant differences were found between patients with Guillain Barre syndrome treated with plasma exchange and patients treated with intravenous immune globulins either alone or in combination with high dose methylprednisolone. Conclusion- It can be concluded that tentative and the gap in current research should not be interpreted as proof that multidisciplinary care is ineffective. Further research is needed into appropriate study designs; outcome measurement; caregiver needs; and the evaluation of optimal settings, type, intensity or frequency...

Premature Ejaculation (PE) is one of the most common forms of Sexual Dysfunction and is thought to affect up to 30 % of men. This is the most frequently encountered sexual complaint of men and couples. The physical problem associated with premature ejaculation can be simply described as “over-sensitivity” of the penis. Psychological causes of PE are often associated with “performance anxiety” – anxiety relating to sexual intercourse. The most common treatment today is the oral treatment with phosphodiesterase -5 (PDE-5) inhibitors. There are currently three different inhibitors available Sildenafil, Vardenafil, and Tadalafil. Sildenafil citrate is a drug of choice used in the treatment of premature ejaculation disorder. It was licensed for use in the United States in 1998; Sildenafil has shown in studies that it improves ED in men regardless of disease etiology, severity of disease, or even age. Transdermal gel has gained more and more importance because the gel based formulations are better percutaneously absorbed than creams and ointment bases. Transdermal drug delivery systems are defined as...
