Size-selective harvesting is one of the most widespread anthropogenic impacts on marine species. The loss of larger (older) individuals due to such harvesting has numerous cascading effects on the biology of affected species and populations, including changes in life history, demography, reproductive output, and even ecological interactions (Fenberg & Roy 2008). Size-selective harvesting has be...

Doppler studies on haemodynamics of the cardiovascular system and intra-abdominal organ perfusion in non-pregnant individuals are usually performed by cardiologists and radiologists. Specialists in Maternal-Fetal Medicine are also familiar with cardiovascular Doppler sonography, however, they mostly focus on the fetal (Malcus, 2004) or uteroplacental circulation (Abramowicz and Sheiner, 2008; P...

Adult neurogenesis, a concept emergent in the late 1990s, is the generation of new neurons in the adult brain. This process occurs thank to cells who have this proliferative feature, named as Neural Stem Cells (NSCs). Neural Stem Cells (NSCs) are primary progenitors who can generate the two neural types (neurons and glia). Classically it was assumed that NSCs are only present in the embryo, but...

Background and Objective: Mobilization of Hematopoietic Stem Cells (HSCs) for transplantation and the importance of -adrenergic signals in induction of this process have been well investigated. However, little is known about the role of -adrenergic signals in mobilization of HSCs and factors influenced by these signals. The Chemokine Stromal Derived Factor -1 (SDF-1) which is expressed by hum...
