Platelet-Rich Plasma (PRP) is a low-cost procedure to deliver high concentrations of autologous growth factors (GFs). Platelet activation is a crucial step that might influence the availability of bioactive molecules and therefore tissue healing. Activation of PRP from ten voluntary healthy males was performed by adding 10% of CaCl2, 10% of autologous thrombin, 10% of a mixture of CaCl2 + throm...

Background Wk 24 TRANxITION study data showed patients transitioned from immediate release nevirapine (NVP IR) twice daily (BID) to NVP extended release (NVP XR) once-daily (QD) demonstrated non-inferior efficacy to patients continuing on IR NVP BID [1]. Similar safety was reported for NVP XR and NVP IR in the VERxVE study [2]. Wk 48 efficacy/safety data from TRANxITION study are presented here.

A solution containing 198Hg in the form of HgCl2 was added to a 4 m2 area of desert soils in Nevada, and soil Hg fluxes were measured using three dynamic flux chambers. There was an immediate release of 198Hg after it was applied, and then emissions decreased exponentially. Within the first 6 h after the isotope was added to the soil, approximately 12 ng m(-2) of 198Hg was emitted to the atmosp...

In recent years, in association with progress and innovation in the field of pharmaceutical technology, there has been an increasing effort to develop prolonged release dosage forms for many drugs. Correspondingly, a growing number of new prolonged release dosage forms have been submitted for regulatory approval. Prolonged release dosage forms have many advantages in safety and efficacy over im...

Introduction The dissolution test as defined in the United States Pharmacopoeia (1) is used in judging the quality of pharmaceutical products. Dissolution testing is a method for evaluating physiological availability that depends upon having the drug in a dissolved state. The USP Dissolution testing involves three stages and the acceptance criteria are defined for each stage as a function of a ...

BACKGROUND Immediate-release (IR) quetiapine has been used to treat schizophrenia since 1997, although all the principal placebo-controlled trials have >50% missing outcome data. New studies with relatively lower rates of participant withdrawal have since been published. AIMS To assess the efficacy and adverse effects of quetiapine IR for schizophrenia, with consideration of outcome quality a...

We used decision-analysis modeling to compare costs and outcomes of clarithromycin extended-release (Biaxin XL, Abbott Laboratories, Abbott Park, Illinois, USA) and clarithromycin immediate-release (Biaxin, Abbott Laboratories, Abbott Park, Illinois, USA) for outpatients with lower respiratory tract infections (LRTI). More patients achieved clinical cure with extended-release (83.9%) versus imm...
