The inability to identify natal origins (i.e., individual rivers and hatcheries) of adult Pacific salmon in the ocean has impeded our understanding of their ocean ecology and the management of mixed-stock fisheries. Strontium isotope (87Sr : 86Sr) ratios recorded in otoliths of fall-run Chinook salmon (Oncorhynchus tshawytscha) from all major natural and hatchery spawning sites in the Californi...

Mechanisms of clathrindependent endocytosis Although clathrin-mediated internalization has been investigated for many years, new technologies keep providing us with novel insights into its underlying mechanisms, with an unprecedented scale down to molecular details regarding the structure and dynamics of the proteins involved. The plasticity of clathrin-mediated internalization was well illustr...

Development of energy-efficient and high-performance bioreactors requires progress in methods for assessing the key parameters biosynthesis process. With a wide variety approaches determining phase contact area gas–liquid flows, question obtaining its accurate quantitative estimation remains open. Particularly challenging are issues getting information about mass transfer coefficients instantly...

Background—Although myocardial ischemia is known to be significantly related to the development of coronary collateral vessels (CCVs), there is considerable variation between patients with ischemic heart disease in the presence of collateral development. The nature of this variability is not well known. Likewise, it remains unclear whether diabetes mellitus (DM) has any effect on CCVs. The aim ...
