National, European licensing examinations or none at all?
The unification of Europe in higher education in general and in medical education in particular is progressing. Since the Bologna declaration most of the European countries are in the process of introducing a two-cycle training programme in higher education that also affects medical training programmes (Patricio et al. 2008). Within the European legislature there is free mobility of professiona...
متن کاملAll-or-none potentiation at CA3-CA1 synapses.
The molecular mechanisms underlying long-term potentiation in the hippocampus have received much attention because of the likely functional importance of synaptic plasticity for information storage and the development of neuronal connectivity. Surprisingly, it remains unclear whether activity modifies the strength of individual synapses in a digital (all-or-none) or analog (graded) manner. Here...
متن کاملNeocytolysis: none, one or many? A reappraisal and future perspectives
Neocytolysis is the hypothesis formulated to explain experimental evidence of selective lysis of young red blood cells (RBCs) (neocytes) associated with decreased plasma levels of erythropoietin (EPO). In humans, it appears to take place whenever a fast RBC mass reduction is required, i.e., in astronauts during the first days of spaceflight under weightlessness, where a fast reduction in plasma...
متن کاملOn the all-or-none rule of conscious perception
What are the true functional underpinnings of perception, emotion, consciousness, and subconscious processes remains an unsolved question (Alivisatos et al., 2012). For example, it seems somewhat mysterious how one and the same structure of neural circuits—the human brain—sometimes allows conscious experience and sometimes does not allow it. We even do not know whether this owes to the alternat...
متن کاملGPRC6A: Jack of all metabolism (or master of none)
BACKGROUND GPRC6A, a widely expressed G-protein coupled receptor, is proposed to be a master regulator of complex endocrine networks and metabolic processes. GPRC6A is activated by multiple ligands, including osteocalcin (Ocn), testosterone (T), basic amino acids, and various cations. SCOPE OF REVIEW We review the controversy surrounding GPRC6A functions. In mice, GPRC6A is proposed to integr...
