Molecular basis of the effect of MMP-9 on the prostate bone metastasis: A review.

Introduction And Objective: Prostate cancer (PCa) is the second most common cancer in men especially after 50 years old. The metastasis of said cancer involves a rise for morbidity, metastasizing 90% of the occasions on bone. Metalloproteinases (MMPs) are involved in the process of bone formation and they are postulated to be involved in the process of metastasizing, in particular MMP-9.

Structure-based design of new KSP-Eg5 inhibitors assisted by a targeted multicomponent reaction.

An integrated multidisciplinary approach that combined structure-based drug design, multicomponent reaction synthetic approaches and functional characterization in enzymatic and cell assays led to the discovery of new kinesin spindle protein (KSP) inhibitors with antiproliferative activity. A focused library of new benzimidazoles obtained by a Ugi+Boc removal/cyclization reaction sequence generated low-micromolar-range KSP inhibitors as promising anticancer prototypes. The design and functional studies of the new chemotypes were assessed by computational modeling and molecular biology techniques.

Heart rate recovery normality data recorded in response to a maximal exercise test in physically active men.

Background: Despite a growing clinical interest in determining the heart rate recovery (HRR) response to exercise, the limits of a normal HRR have not yet been well established.

Purpose: This study was designed to examine HRR following a controlled maximal exercise test in healthy, physically active adult men.

Methods: The subjects recruited (n = 789) performed a maximal stress test on a treadmill.

Urinary biopyrrins: potential biomarker for monitoring of the response to treatment with anxiolytics.

During periods of psychological stress, excess amounts of free radicals are produced. Bilirubin oxidative metabolites (biopyrrins; BOM) are generated from bilirubin as a result of its scavenging action against free radicals. We investigated whether the urinary excretion of biopyrrins is altered by anxiolytics.

Effects of fluoxetine on the oxidative status of peripheral blood leucocytes of restraint-stressed mice.

Emotional stress can be viewed as a cause of adverse circumstances that induces a wide range of biochemical and behavioural changes. Oxidative stress is a critical route of damage in various psychological stress-induced disorders such as depression. Antidepressants are widely prescribed to treat these conditions; however, no animal study has investigated the effect of selective serotonin reuptake inhibitors (SSRIs) on the levels of intracellular reactive oxygen species in peripheral blood leucocytes of stressed mice.
