In several recent models of invertebrate skeletogenesis, Ca-carbonate crystallization occurs within a liquid-filled chamber. No explanation is given neither for the simultaneous occurrence of distinct polymorphs of Ca-carbonate within these liquid volumes, nor for the spatial arrangement of the mineral units which are always organized in species-specific structural sequences. Results of a serie...

The vestibular nervous system senses linear and angular acceleration upon the head during postural change generates nerve activity changes. autonomic regulates involuntary physiologic processes throughout peripheral central systems. systems interplay several brain regions to maintain homeostasis changes, called vestibulo-autonomic reflex. In this review, we first contemplated anatomic propertie...

background: autologous skin graft is frequently used in the field of plastic, and reconstructive surgery. the engraftment is dependent upon revascularization and angiogenesis, which can be regulated by different factors. in addition to its hematopoietic effects, erythropoietin is shown to positively affect the wound healing process. objectives: we studied effects of human erythropoietin on reva...
