Abstract: Introduction: The controlled release of medicaments in the management diabetes is desirable to have a better therapeutic activity drug. Objectives: In present study hydrogels were prepared as drug delivery system taking Rosiglitazone model Materials and Methods: Hydrogels created using Free Radical Polymerization approach, with crosslinker N, N′-Methylene bisacrylamide serving binding...

A hydrogel is a water-insoluble three-dimensional polymer network that has the ability to absorb body fluids in biological environment. Such formed through chemical crosslinking mechanisms such as optical polymerization, enzymatic reactions and physical temperature pH dependent processes ionic crosslinking. Physical hydrogels are weak secondary force by covalent forces. Various polymers of natu...

Rosacea is a chronic inflammatory disease of the skin mainly central facial region, having gender and age correlations. Currently, more data accumulating on analysis rosacea phenotypes, scientific discussions are underway feasibility switching from subtype classification to phenotypic justify individualized approaches therapy. The based manifestations distinguishes diagnostic signs main seconda...

Reduced glutathione is among the substances of physiological occurrence which stimulate water uptake by isolated rat liver mitochondria (l-3). The water uptake produced by glutathione is of special interest since it differs in some respects from that induced by other agents such as phosphate, thyroxine, and phlorizin (l-6). Perhaps the most significant difference is that glutathione-swollen mit...

1 Wallaba (Eperua falcata) is a tropical wood which is known to have naturally low swelling 2 characteristics. Samples of wallaba heartwood were subjected to differential solvent 3 extraction. Wood pieces that were extracted with methanol experienced significantly higher 4 swelling after rehydration from oven dry to 96% relative humidity in comparison to non-5 extracted samples and samples extr...

Introduction: Extra-pulmonary tuberculosis (EPTB) arising in extra-oral region in head and neck are rare, and when swellings arise from other sites such as infraorbital region, cheek, etc, tuberculosis is not usually considered for the differential diagnosis (DD) and often the diagnosis is missed and appropriate treatment is delayed. Case Report: We report a rare entity of pri...

BACKGROUND Colorectal cancer is the third commonest cause of cancer death in UK. It commonly metastasises to the liver but rarely to small bones. CASE PRESENTATION We describe a case of a patient with adenocarcinoma of the descending colon who presented preoperatively with a right supraclavicular swelling. Subsequent imaging and cytology of the lesion revealed this to be a metastasis to the r...

The most common benign salivary gland tumor is pleomorphic adenoma. They can attain giant proportions and weigh several kilograms. They can cause facial disfigurement and, if untreated, could lead malignant transformation. This image depicts a 7.5 kg pleomorphic adenoma of right submandibular gland with malignant change in a 55-year-old male.

DOI: 10.1590/S1679-45082014AI2606 A 22-day-old male infant, the first child of nonconsanguineous parents, who was delivered from a followed-up and normal pregnancy, and without alterations in analytical and echographic evaluation. He was born by cesarean section at 39 weeks, because the labor failed to progress, with Apgar score of 9 at 1 minute and of 10 at 5 minute, weighting 3,240g at birth ...
