It is true that we have a global fisheries crisis, but it is equally true that we already have the tools to understand its causes and overcome it. One of the elements of this toolkit is the Food and Agriculture Organization (UN) Code of Conduct for Responsible Fisheries, launched in 1995 and endorsed by all of FAO's member states. The Code, a mixture of(More)
The underlying mechanism of isoflurane-induced cognitive dysfunction in older individuals is unknown. In this study, the effects of isoflurane exposure on the hippocampal blood-brain barrier (BBB) in aged rats were investigated because it was previously shown that BBB disruption involves in cognitive dysfunction. Twenty-month-old rats randomly received 1.5%(More)
Melatonin is an endogenous hormone with neuroprotective effects. Melatonin levels in elderly patients are reduced after surgeries that require anaesthesia. Whether reduced melatonin levels are important for postoperative cognitive dysfunction (POCD) remains unclear. Here, we investigated the effects of melatonin on cognitive dysfunctions induced by(More)

Conventional open netcage systems for salmon aquaculture are under scrutiny and criticism partially because they are believed to generate adverse environmental impacts on other resource users and the surrounding environment. One alternative to preventing or minimizing these impacts is to use enclosed systems. Experience indicates that these enclosed systems(More)
Melatonin exerts many physiological effects via melatonin receptors, among which the melatonin-2 receptor (MT2 ) plays a critical role in circadian rhythm disorders, Alzheimer's disease and other neurological disorders. A melatonin replacement strategy has been tested previously, and MT2 was a critical target during the process. cAMP response element(More)
BACKGROUND Difficult airway may result in significant morbidity and mortality. Proficient airway evaluation, therefore, is one of the key elements in the safe conduct of anesthesia. A three-dimensional (3D) printing model was recently introduced for medical application. 3D printing is a fast, convenient, and relatively affordable technique. We present a(More)
