New development on hysteroscopy for endometrial cancer diagnosis: state of the art.

Endometrial cancer (EC) is the most common gynecologic cancer diagnosed in developed countries and represents the second most frequent gynecologic cancer-related cause of death following ovarian cancer. There are 2 subtypes of EC. Type I tumors (endometrioid adenocarcinoma) representing 85-90% of the cases.

Kinetic Changes of Plasma Renin Concentrations Predict Acute Kidney Injury in Cardiac Surgery Patients.

The renin-angiotensin-aldosterone system is a major pathway in regulating blood pressure, glomerular filtration, and fluid homeostasis. During inflammatory diseases, generation of angiotensin II might be disturbed, leading to increased renin concentrations. Cardiac surgery and the use of cardiopulmonary bypass both induce inflammatory response and cardiovascular instability, which can contribute to acute kidney injury (AKI).

Pathological changes in the COPD lung mesenchyme--novel lessons learned from in vitro and in vivo studies.

Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of death worldwide and, in contrast to the trend for cardiovascular diseases, mortality rates still continue to climb. This increase is in part due to an aging population, being expanded by the "Baby boomer" generation who grew up when smoking rates were at their peak and by people in developing countries living longer. Sadly, there has been a disheartening lack of new therapeutic approaches to counteract the progressive decline in lung function associated with the disease that leads to disability and death.
