Perceptive solutions to anti-filarial chemotherapy of lymphatic filariasis from the plethora of nanomedical sciences.

Introduction: Growing interest in the application of nanotechnology to treat lymphatic filariasis (LF) implies that the imminent medical arsenal of this interesting technology is attractive for health authorities. Currently, they are completely dependent on friendly oral mass drug (anti-filarials) administration to eliminate this morbid disease and are now looking for new alternatives to bring about further improvements.

Areas Covered: A plethora of issues affecting the oral bioavailability of the mainstay human lymphatic filarial drugs, leading to meager pharmacokinetics and pharmacodynamics issues in anti-filarial chemotherapy are identified.

Improved antifilarial activity of ivermectin in chitosan-alginate nanoparticles against human lymphatic filarial parasite, Brugia malayi.

The current antifilarial treatments are not up to the mark partly due to deep location of filarial parasites in the human lymphatic system. We report here on the improvement in the antifilarial activity of ivermectin (IVM) using chitosan-alginate nanoparticles prepared by modified complex coacervation method. The nanoparticles were spherical having 155 nm size and 4.

Nanopharmaceuticals to target antifilarials: a comprehensive review.

Introduction: Currently emphasized conventional chemotherapies for the elimination of lymphatic filariasis (LF) are imperfect due to unfocused targeting of poorly water-soluble antifilarial drugs. The profound location of drug targets (filarial parasites or wolbachia) within the complex anatomy of lymphatic tissues often necessitates prolonged treatment schedules with high doses leading to undesired side effects and poor patient compliance. Therefore, we need to reformulate antifilarial drugs taking the advantages of nanotechnology through a wide range of nanomedical carriers, which improve drug efficacy, increase bioavailability, and diminish toxicity.

Curcumin loaded nano globules for solubility enhancement: preparation, characterization and ex vivo release study.

Curcumin in spite of being an effective chemotherapeutic agent against different type of cancer, suffer from the problem of low systemic bioavailability due to low aqueous solubility, extensive intestinal metabolism and first-pass metabolism when administered via the oral route. The aim of present investigation was to evaluate the potential of nano globules based nanoemulsion formulation for the solubility enhancement of curcumin. The nano globules based formulation was developed using Labrafac Lipophile WL 1349, Unitop FFT 40, PEG 400 and distilled water as an oil, surfactant, co-surfactant and aqueous phase respectively using aqueous titration method.

The interactive effect of elevated temperature on deltamethrin-induced biochemical stress responses in Channa punctata Bloch.

There are reports showing interactive effect of environmental factors with the toxic outcome of chemicals. We studied the interactive effect of elevated temperature as an abiotic stressor on deltamethrin-induced biochemical stress responses in a freshwater fish, Channa punctata Bloch. Heat stress (∼12°C above ambient temperature for 3h) and pesticide exposure (deltamethrin 0.

Conundrum and therapeutic potential of curcumin in drug delivery.

Turmeric, the source of the polyphenolic active compound curcumin (diferuloylmethane), has been used extensively in traditional medicine since ancient times as a household remedy against various diseases, including hepatic disorders, cough, sinusitis, rheumatism, and biliary disorders. In the past few decades, a number of studies have been done on curcumin showing its potential role in treating inflammatory disorders, cardiovascular disease, cancer, AIDS, and neurological disorders. However, the main drawback associated with curcumin is its poor aqueous solubility and stability in gastrointestinal fluids, which leads to poor bioavailability.

Comparison of effects of manual versus ventilator hyperinflation on respiratory compliance and arterial blood gases in patients undergoing mitral valve replacement.

Objective: To compare the effects of manual hyperinflation (MHI) and ventilator hyperinflation (VHI) delivered to completely sedated and paralyzed patients undergoing mitral valve replacement (MVR) while maintaining minute ventilation.

Methods: This was a randomized study with a 2-group, pre-test, post-test experimental design. Effects of hyperinflation were studied on static compliance (C(stat)), dynamic compliance (C(dyn)), oxygenation (Pao(2):Fio(2)), partial pressure of carbon dioxide in arterial blood (Paco(2)), and cologarithm of activity of dissolved hydrogen ions in arterial blood (pH).
