objective(s): pharmaceutical industries are leading to improved medications that can target diseases more effectively and precisely. researchers have intended to reformulate drugs so that they may be more safely used in human body. the more targeted a drug is, the lower its chance of triggering drug resistance, a cautionary concern surrounding the use of broad-spectrum antibiotics. the aim of t...

Poly (ADP-ribose) polymerase inhibitors (PARP inhibitor) is a new targeted drug for metastatic prostate cancer in which the patient has mutation on homologous repair gene including BRCA1/2 gene. This was first gene-based agent and there were more than 5 available drugs PARP inhibitors. Only 4 approved clinical use patients with from U.S. Food Drug Administration. review article deals overview o...

in this study, doxycycline hyclate release behavior from in situ forming drug delivery systems investigated. these systems based on poly()lactide-co-glycolide)(50:50 dissolved in n-methyl-2-pyrrolidone that were evaluated in different concentrations. these systems are useful for local treatment of periodontal diseases. uv spectroscopy is used to determine drug concentration in release medium. a...

microspheres formulated from poly (d,l-lactic-co-glycolide) (plga), a biodegradable polymer, have been extensively evaluated as a drug delivery system. in this study, the preparation, characterization and drug release properties of the plga microspheres were evaluated. simvastatin (sim)-loaded plga microspheres were prepared by oil-in-water emulsion/solvent evaporation method. the microspheres ...

Many genes expressed in the human genome have not been identified despite intensive efforts. We observed that the presence of long poly(dA/dT) sequences in the 3' end of cDNA templates contributes significantly to this problem, because the hybrids formed randomly between poly(dA) and poly(dT) sequences of unrelated cDNA templates lead to loss of many templates in the normalization/subtraction r...

Numerous Scientists have discovered the procedure of nanotechnology, explicitlynanofibers, asdrug delivery systems for transdermal uses. Nanofibers canbe used to deliver drugs and are capable of controlled release for a continued periodof time. Poly (Lactic Acid) (PLA) is the lastly interesting employed synthetic polymer in biomedical application owing to its well categorized biodegradable prop...

The increasing use of nanoparticles in the pharmaceutical industry is generating concomitant interest in developing nanomaterials that can rapidly penetrate into, and permeate through, biological membranes to facilitate drug delivery and improve the bioavailability of active pharmaceutical ingredients. Here, we demonstrate that the permeation of thiolated silica nanoparticles through porcine ga...
