Problem statement: Hepatitis B is a major public health problem, killing 1-2 million people annually, despite the introduction of an effective vaccine in 1982. Approximately 400 million persons worldwide have chronic hepatitis B. This is due to problems associated with vaccine delivery, stability and cost. Hence the present challenge in Vaccinology is to develop safer, cheaper and easy-todelive...

INTRODUCTION Hemoptysis constitutes a common and urgent medical problem. Swift and effective management is of crucial importance, especially in severe, life-threatening cases. In cases of idiopathic hemoptysis, in which no underlying pulmonary pathology can be identified, treatment is challenging. We report our experience with bronchial artery embolization in the treatment of massive idiopathic...

BACKGROUND NK4 inhibits vascularisation in tumour tissues, thereby arresting tumour growth. However, the antitumour efficacy of individual antiangiogenic molecules expressed in vivo is not sufficiently potent to induce regression in animal models. One of the strategies to overcome this disadvantage is to use chemotherapy. MATERIALS AND METHODS This study evaluated the efficacy of combining NK...

We present a comparative study of two-photon excited fluorescence (TPEF) and second harmonic generation (SHG) imaging in turbid media at 800- and 1300-nm excitation. The depth-dependent decay of TPEF and SHG signals in turbid tissue phantoms is used to estimate the impact of light scattering on excitation intensity at each wavelength. A 50 to 80% increase in scattering length is observed using ...

Experimental studies using murine tumor models have demonstrated that potent systemic immunity can be generated using tumor vaccines engineered by gene transfer to secrete certain cytokines. The underlying physiological principle behind these strategies involves the sustained release of high doses of cytokine at the site of the tumor. In some cases, this paracrine approach appears to enhance tu...

the purpose of this study was to prepare and characterize nimodipine loaded microspheres using ethyl cellulose (ec) as a carrier polymer through an emulsion solvent evaporation method. these evaluations characterized the pattern of drug release from prepared microspheres. nimodipin loaded microspheres were prepared using an emulsification solvent evaporation method. the effect of process variab...

the purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934p as mucoadhesive polymer and ethyl cellulose as carrier ...

OPINION STATEMENT Stem cell therapy is a promising therapeutic option for severe cardiac diseases that are resistant to conventional therapies. To overcome the unsatisfactory results of most clinical researches on stem cell injections to an injured heart, we are developing bioengineered cardiac tissue grafts using pluripotent stem cell-derived cardiomyocytes and vascular cells. We have validate...

objective(s): the purpose of the current study was to assess the feasibility of microspheres from biocompatible polymer for oral bioavailability (ba) enhancement of potent sulfonamide- type loop diuretic- furosemide - which used in the treatment of congestive heart failure, caused edema, cirrhosis, renal disease and as an adjunct in acute pulmonary edema. the comparatively poor and inconstant b...

Nanotechnology plays an important role in advanced biology and medicine research particularly in the development of potential site-specific delivery systems with lower drug toxicity and greater efficiency. These include microcapsules, liposomes, polymeric microspheres, microemulsions, polymer micelles, hydrogels, solid nanoparticles etc. In the present study, preparation and characterization of...
