Probiotics are live microorganisms that confer many health benefits to the host when administered in adequate quantities. These health benefits have garnered much attention towards probiotics and have given an impetus to their use as dietary supplements for the improvement of general health and as adjuvant therapies for certain diseases. The increased demand for probiotic products in the recent times has provided the thrust for probiotic research applied to several areas of human biology. The advances in genomic technologies have further facilitated the sequencing of the genomes of such probiotic bacteria and their genomic analyses to identify the genes that endow the beneficial effects they are known to exert. This work reviews the application of genomic strategies on probiotic bacteria, while providing the details about the probiotic strains whose genome sequences are available. It also consolidates the genomic tools used for the sequencing, assembly and annotation of the probiotic genes and how it has helped in comparative genomic...

In this article, we have reviewed several features of nanomicelles relating to their general properties, preparation and characterization techniques, and their applications in the areas of ocular drug delivery system. Nanomicelles can be rummage-sale as ‘smart drug carriers’ for targeting certain areas of the eye by making them stimuli-sensitive or by attachment of a specific ligand molecule onto their surface. In present scenario, the major challenge for the researchers is ocular drug delivery system as eye is the most sensitive organ in our body. Topical eye drop is the best suited way for delivery of drugs for the treatment of anterior segment of the eye. Delivery of the drugs to the targeted areas is restricted by the various barriers and even the amount instilled do not remain there for a long duration of time. In the past many years scientist are working on providing the masses the way for delivering drug in a novel, safe and patience compliance manner. The aided the basic delivery by providing the administration through...

Amid the previous couple of years, the improvement of powerful, experimental innovations for treatment of cardiovascular arrhythmias has surpassed the pace at which itemized information of the basic science has aggregated. Cardiac arrhythmia is a group of conditions in which the heartbeat is irregular, either too fast, or too slow and is characterized by abnormal electrical conduction in the heart resulting in ineffective pumping heart rate and rhythm that is not physiologically justified. Cardiac arrhythmias are commonly classified as tachycardia (supraventricular or ventricular) or bradycardias. The specialist management of arrhythmias has changed significantly over the past decade. Abnormal impulse conduction results in reentrant excitation. Usually a combination of slowed conduction and unidirectional conduction block provides the conditions necessary for re-entry to occur. This article outlines current management strategies for atrial flutter and atrial fibrillation, with particular emphasis on curative strategies with catheter ablation and the recent data on rhythm compared with rate control strategies. The biology of arrhythmia is largely quantifiable, which allows for systematic analysis that could transform...

The main roles of bile acids as amphiphilic molecules are the micellar solubilization of the lipids, in the course of the welding process and the regulation of cholesterol homeostasis, which is essential as a precursor for the synthesis of bile acids. From the hydrophobic and hydrophilic surfaces of bile acids directly depends the level of their attachment to the receptors, ion channels and their effectiveness in the solubilization of lipid (hydrophobic drugs). The toxicity of membrane of bile acids is mainly determined by their hydrophobicity. We have synthesized the methyl ester of 7α-hydroxy-3-oxo-5β-cholanoic acid. We have reviewed and discussed the effects of the structure of bile acids to their hydrophobicity, which is expressed by the retention parameters by reverse phase chromatography, and hydrophobic properties, which is represented by partition coefficient 1-octanol / water. It also discusses the role of the lipophilicity of bile acids in their interactions with biological...

Phyllanthus amarus Schum and Thonn herb is in traditional medicine for more than 3000 years. It belongs to a family of Euphorbiaceae and commonly known by the name of carry me seed, stone breaker, gala of wind, etc. It is a branching annual herb of 30 – 60 cm height widely spread throughout tropics and sub-tropics as a weed. Phyllanthus amarus is gaining momentum for its hepatoprotective, anti-carcinogenic, anti-bacterial, anti-viral, anti-inflammatory and more activities as it contains different combinations of secondary metabolites, which render them medicinal properties. The major class of bioactive compounds like alkaloids, flavonoids, lignans, sterols, tannins, triterpenes and volatile oils has been isolated. Lignans like phyllanthin and hypophyllanthin, flavonoids like quercetin were isolated from the leaves of P. amarus. This review is an effort to represent the phytochemicals and their pharmacological properties which constantly addresses a challenge because of a large number of compounds present as a mixture in the extract with trace...
