OBJECTIVES: The breakthrough advancements in scientific medical research have greatly improved our understanding of the pathogenesis of depression, encouraging drug discoverers to take a shorter path than ever through drug repurposing to generate new antidepressant medications. In addition to reduced noradrenergic and serotonergic neurotransmission in the brain, other coincidence features such as glutamate neurotoxicity, inflammation and/or cerebrovascular insufficiency are implicated in the pathogenesis of major depressive disorder and late-life depression...

For some years now, we have entered the genomic age of tumour genotyping from a medical point of view. Technological breakthroughs in both biology and information science now allow a genomic analysis of cancers in everyday medical practice with, in some case, a major impact on patient care not only for the choice of therapy (i.e. EGFR mutations in lung adenocarcinoma), but also for diagnosis and monitoring of the disease. Tumour genotyping is performed from formalin-fixed paraffin-embedded tissues used for diagnosis of cancer...

BACKGROUND: Stroke is a leading cause of death and disability, and despite intensive research, few treatment options exist. However, a recent breakthrough in cell therapy is expected to reverse the neurological sequelae of stroke. Although some pioneer studies on the use of cell therapy for treating stroke have been reported, certain problems remain unsolved. Recent studies have demonstrated that bone marrow stromal cells (BMSCs) have therapeutic potential against stroke. We investigated the use of autologous BMSC transplantation as a next-generation cell therapy for treating stroke...

Breakthrough advances in medicine almost uniformly result from the translation of new basic scientific knowledge into clinical practice, rather than from assessment, modification or refinement of current methods of diagnosis and treatment. However, as is intuitively understood, those most responsible for scientific conception and creation-scientists - are generally not the ones applying these advances at the patient's bedside or the operating room, and vice versa. Recognition of the scarcity of clinicians with a background that prepares them to develop new basic knowledge, and to critically evaluate the underlying scientific basis of methods of diagnosis and treatment, has led to initiatives including federally funded Physician-Scientist programs, whereby young, motivated scholars begin a rigorous training, which encompasses education and mentorship within both medical and scientific fields, culminating in the conferment of both MD and PhD degrees...

The last decade has seen a breakthrough in the treatment of erectile dysfunction (ED) with the advent of phosphodiesterase-5 inhibitors. There are few population-based observational studies on the prevalence of use of these drugs. We conducted a cross-sectional population-based study in the city of Pelotas (Brazil). Our sample comprised 1,082 men aged 20 years or older who answered a confidential and self-administered questionnaire. Prevalence of EDD use was 5% (IC95% = 4%;7%). ED and advanced age were strongly associated with a higher prevalence of EDD use...

Optoacoustic imaging emerged in early 1990s as a new biomedical imaging technology that generates images by illuminating tissues with short laser pulses and detecting resulting ultrasound waves. This technique takes advantage of the spectroscopic approach to molecular imaging, and delivers high-resolution images in the depth of tissue. Resolution of the optoacoustic imaging is scalable, so that biomedical systems from cellular organelles to large organs can be visualized and, more importantly, characterized based on their optical absorption coefficient, which is proportional to the concentration of absorbing chromophores...
