PURPOSE: The use of bisphosphonates for osteoporosis is effective in reducing the risk of fractures. However, oral formulations are sometimes not well tolerated or are contraindicated. Due to its availability in Brazilian public health system, pamidronate is frequently prescribed for osteoporosis, despite the lack of studies demonstrating its anti-fracture efficacy and the absence of FDA or EMEA approval for this purpose. The aim of this study was to evaluate the bone mineral density (BMD) response to pamidronate in a group of women with osteoporosis in a tertiary care hospital...

ETS proto-oncogene 1, transcription factor (ETS1) is involved in various immune responses. Genome-wide association studies on systemic lupus erythematosus in Chinese populations identified the association of ETS1 polymorphism in 3' untranslated region, rs1128334A, which was associated with lower ETS1 expression. In view of substantial sharing of susceptibility genes across multiple autoimmune diseases, we examined whether ETS1 is associated with a rare autoimmune rheumatic disease, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV)...

BACKGROUND: Periostin (osteoblast-specific factor OSF-2) is a secreted protein occurring in seven known isoforms, and it is involved in a variety of biological processes in osteology, tissue repair, oncology, cardiovascular and respiratory systems or allergic manifestations. To analyze functional aspects of periostin, or the ability of periostin as potential biomarker in physiological and pathological conditions, there is the need for a precise, well-characterized assay that detects periostin in peripheral blood...

In this article, we proposed a risk assessment strategy for CYP3A time-dependent inhibition (TDI) during drug discovery based on a thorough retrospective study of 13 reference drugs, some of which are known to have in vitro TDI potential but have unknown clinical relevance. First, the traditional parameter kinact/KI, recommended by regulatory authorities for necessity decision making in clinical drug-drug interaction (DDI) studies, was investigated as a predictive index for clinical TDI liability. The cutoff value of 1...

Liver disease can alter the disposition of xenobiotics and endogenous substances. Regulatory agencies such as the Food and Drug Administration and the European Medicines Evaluation Agency recommend, if possible, studying the effect of liver disease on drugs under development to guide specific dose recommendations in these patients. Although extensive research has been conducted to characterize the effect of liver disease on drug-metabolizing enzymes, emerging data have implicated that the expression and function of hepatobiliary transport proteins also are altered in liver disease...

Although vaccines would be the ideal tool for control, prevention, elimination, and eradication of many infectious diseases, developing of parasites vaccines such as malaria vaccine is very complex. The most advanced malaria vaccine candidate RTS,S, a pre-erythrocytic vaccine, has been recommended for licensure by EMEA. The results of this phase III trial suggest that this candidate malaria vaccine has relatively little efficacy, and the vaccine apparently will not meet the goal of malaria eradication by itself...

PURPOSE: Successful in vitro fertilization (IVF) relies on sound laboratory methods and culture conditions which depend on sensitive quality control (QC) testing. This study aimed to improve the sensitivity of mouse embryo assays (MEA) for detection of mineral oil toxicity. METHODS: Five experiments were conducted to study modifications of the standard mouse embryo assay (MEA) in order to improve sensitivity using clinical grade mineral oil with known peroxide concentrations...

BACKGROUND: DNA damage response (DDR) defects imply genomic instability and favor tumor progression but make the cells vulnerable to the pharmacological inhibition of the DNA repairing enzymes. Targeting cellular proteins like PARPs, which cooperate and complement molecular defects of the DDR process, induces a specific lethality in DDR defective cancer cells and represents an anti-cancer strategy. Normal cells can tolerate the DNA damage generated by PARP inhibition because of an efficient homologous recombination mechanism (HR); in contrast, cancer cells with a deficient HR are unable to manage the DSBs and appear especially sensitive to the PARP inhibitors (PARPi) effects...

Most previous assays for thiopental are time-consuming due to laborious sample extraction steps prior to analysis using gas chromatography or high pressure liquid chromatography. Here, we describe the first high-throughput liquid chromatography - tandem mass spectrometry (LC-MS/MS) method for quantification of thiopental concentrations in samples of human plasma. Robotic on-line solid phase extraction (SPE) was used to elute the analytes of interest from samples of human plasma (50μL) loaded onto C18 SPE cartridges to which were added aliquots (50μL) of internal standard solution (thiopental-d5 100ng/mL) and 0...

Varicella-zoster virus (VZV) infection causes two distinct clinical conditions. Primary varicella infection results in chickenpox, a contagious rash illness typically seen among children. VZV can reactivate years after the initial infection to cause herpes zoster (HZ) and lead to post-herpetic neuralgia, a common complication resulting in persistent pain that may last for years after the zoster rash resolves. A person's risk of having longer lasting and more severe pain associated with HZ increases with age...

OBJECTIVE: There is increasing evidence that the ATP generating enzyme creatine kinase (CK) is involved in hypertension. The enzyme is central to the regeneration of ATP by using creatine phosphate and ADP, thereby forming creatine and ATP. We recently showed that beta-guanidinopropionic acid (GPA), a creatine analogue and competitive CK inhibitor, effectively and safely reduced blood pressure in the spontaneously hypertensive rat. This renders GPA to be potentially beneficial for blood pressure lowering...

INTRODUCTION: The sphingosine-1-phosphate (S1P) regulates diverse biological functions including cell proliferation, endothelial cell chemotaxis, angiogenesis, immune cell trafficking, mitogenesis, heart rate. The first-in-class S1P1,3-5-R pan-agonist fingolimod (FTY720) was approved by the FDA and EMEA for the treatment of relapsing-remitting multiple sclerosis, though the most common adverse effect is bradycardia which occurs in the early stage of treatment and resolves within the first 24 h despite continuing treatment...

The strong and widespread use of pharmaceuticals, together with incorrect disposal procedures, has recently made these products contaminants of emerging concern (CEC). Unfortunately, little is known about pharmaceuticals' environmental behaviour and ecotoxicity, so that EMEA (European Medicines Agency) released guidelines for the pharmaceuticals' environmental risk assessment. In particular, there is a severe lack of information about persistence, bioaccumulation and toxicity (PBT) of the majority of the thousands of substances on the market...

UNLABELLED: Antibody-mediated rejection (AbMR) is a leading cause of late graft loss in kidney transplant recipients, accounting for up to 60% of late graft failures. AbMR manifests as two distinct phenotypes: the first occurs in the immediate post-transplant period in sensitized patients; the second occurs in the late post-transplant period and has been associated with non-adherence to immunosuppression. The present review summarizes the current treatment options for AbMR, its clinical and economic burden, and approaches for reducing the risk of AbMR...

OBJECTIVES: Poor adherence to antipsychotic treatment is a widespread problem within schizophrenia therapy with serious consequences including increased risks of relapse and rehospitalization. Mounting evidence supports the key roles that nurses play in monitoring patient progress and facilitating long-term treatment adherence. The Adherencia Terapéutica en la Esquizofrenia (ADHES) nurses' survey was designed to assess the opinions of nurses on the causes and management of partial/nonadherence to antipsychotic medication...
