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...

Microalgae and Cyanobacteria (blue-green algae) are photosynthetic prokaryotes used as food by humans. They have gained a lot of attention in recent years because of their potential applications in biotechnology. They have also been recognized as an excellent source of vitamins and proteins and as such are found in health food stores throughout the world. They are reported to be a source of fine chemicals, renewable fuel and bioactive compounds. Bioactive compounds are extra nutritional constituents that typically occur in small quantities in foods. Numerous bioactive compounds appear to have beneficial health effects. Microalgae and Cyanobacteria have been identified as a rich source of biologically active compounds with antiviral, antibacterial, antifungal and anticancer activities. This review is an attempt to consolidate the latest studies and critical research in this field, and to showcase the immense competence of uses of microalgae and cyanobacteria as a potential and promising source of novel...

Starting from plastic industry, today melt extrusion has found its place in the array of pharmaceutical manufacturing processes. Melt extrusion processes are currently applied in the pharmaceutical field for the formulation of variety of dosage forms such as granules, pellets, tablets, implants, transdermal systems & ophthalmic inserts. This technology represents an efficient pathway for increasing the solubility of poorly soluble drugs. The process forms a solid dispersion where the drug is presented in an amorphous & molecularly dispersed state in a carrier. This leads to an increase in solubility, as no lattice energy has to be overcome during dissolution. Melt extrusion is considered to be an efficient technology in the field of formulation of solid dispersions to improve bioavailability with particular advantages over solvent processes. This article highlights on the technology of Hot Melt Extrusion...

This review describes the potential and, in particular, some relevant hazards associated with the use of veterinary drugs, various pharmaceuticals and industrial chemicals that have produced serious environmental risks and affected the life of people along with other animals by posing great health risks. Risk analysis regarding these problems has also been discussed with the measures to handle the problem at global level. The most contentious residues which occur in meat, milk and eggs along with the environment are antibacterial drugs, hormonal growth promoters, heavy metals and industrial chemicals that are producing potential toxic health effects that include systemic toxicity, mutations, cancer, birth defects and reproductive disorders. Systemic toxicity involves changes in the structure and function of organs and organ systems: weight change, structural alterations and changes in organ system or whole animal function. Functional effects may include changes in the lungs, liver, kidneys, cardiovascular function, brain, nervous system activity, behavior and in production of resistance to disease. Furthermore, continued monitoring and periodic reassessment of risks posed by these...
