In recent years, nanoparticles of noble metals such as silver have gained enormous attraction owing to their distinct physical, chemical, and biological properties. the present study, (AgNPs) were synthesized from nitrate (AgNO3) using extracted chitosan reducing agent. The was exoskeleton marine crab Portunus pelagicus. Three different sample solutions prepared 0.02mM AgNO3 in 0.5% (w/v) chito...

Background: Socket preservation using bone graft is one way to minimise resorption and maximise the formation process. Tumor necrosis factor-α (TNF-α) an inflammatory cytokine that affects regenerating osteoblast activity, while osterix (Osx) osteoblast-specific transcription factor activates gene receptors during pre-osteoblast differentiation. The hydroxyapatite (HA) scaffold from crab shells...

A more medial and anterior position of the red aerobic myotomal muscle (RM) and the presence of a vascular counter-current heat exchange system provide the functional elements that facilitate regional RM endothermy in tunas, lamnid sharks and the common thresher shark (Alopias vulpinus). The convergent RM morphology among all species capable of RM endothermy suggests that RM position is a stron...
