Effects of feeding on thermoregulatory behaviours and gut blood ...

The effects of thermoregulatory behaviours on gut blood flow in white sturgeon Acipenser transmontanus before and after feeding was studied using a blood flow biotelemetry system in combination with a temperature preference ... This study shows, for the first time in fish, the correlation between body temperature and gut blood flow during behavioural thermoregulation. Key words: gastrointestinal blood supply, postprandial, temperature preference, chronic measurements ...

How We Measure Blood Flow – Part 1 | The Brain Confounds Everything

Targeted Radioisotope Generator Could Be Used for Molecular ...

Physicians could use this technology to more precisely evaluate blood flow through blood vessels and vital tissues, as well as more accurately target treatment for a broad range of cancers." Using this generator, physicians would be able to ... Tumors showed rapid receptor-specific uptake of the agent with specific activity as high as 200 Ci/umol (a measurement of radioactivity in microcuries per micromolar concentration). Results showed that the generator and kit system ...

new research findings two: Just a Little Belly Fat Can Damage ...

These cells, called endothelial cells, are vital for proper functioning of blood vessels. They control the ability of the vessel to contract and dilate, which in turn controls blood flow. Damage to the endothelium can lead to the vessel not ... Measurements were taken before the study started, after eight weeks of weight gain and again after 16 weeks of weight loss. People who gained weight showed a decrease in the ability of the artery to dilate, the researchers found. ...
