Astrocytes as secretory cells of the central nervous system: idiosyncrasies of vesicular secretion.

Astrocytes are housekeepers of the central nervous system (CNS) and are important for CNS development, homeostasis and defence. They communicate with neurones and other glial cells through the release of signalling molecules. Astrocytes secrete a wide array of classic neurotransmitters, neuromodulators and hormones, as well as metabolic, trophic and plastic factors, all of which contribute to the gliocrine system.

Effects of Art on Surgical Patients: A Systematic Review and Meta-analysis.

Objectives: The aim of the study was to assess the effect of art including ambient features such as music, interior design including visual art, and architectural features on health outcomes in surgical patients.

Background: Healing environments can have a positive influence on many patients, but data focusing on art in surgical patients remain scarce.

Methods: We conducted a systematic search following the PRISMA guidelines from January 2000 to October 2014 on art in surgical patients.

Prevalence of Associated Lesions in Anterior Cruciate Ligament Reconstruction: Correlation With Surgical Timing and With Patient Age, Sex, and Body Mass Index.

Background: Knee instability resulting from anterior cruciate ligament (ACL) rupture is an important risk factor for the onset of meniscal tears and cartilage injuries. A delay of the ligament reconstruction further increases this risk. There is currently no agreement on the right time for surgical ACL reconstruction.
