Putting physiology into the Nobel Prize: 2004 marks 100th anniversary of Pavlov's award

...stion, Pavlov emphasized the neural control of the salivary glands as the "prototype of a general scheme of an innervation mechanism." According to Smith: "The insight was that the psychological and the physiolo-gical intermingled in the function of the central gastric secretory neural center, and, therefore,...

The long road to a promising malaria vaccine started at NYU School of Medicine

...he CS protein coats the parasite when it is in the salivary glands of the Anopheles mosquito. At that stage it is a crescent-shaped and called sporozoite, a stage in the complex life cycle of the parasite before it invades the human liver and causes devastating illness. The CS protein has been an...

Forsyth scientists find three bacteria associated with oral cancer

...rs for OSCC. And, in fact, we found that elevated salivary counts of the three bacteria correctly identified 80% of individuals with oral cancer and 83% of controls." If their findings are replicated in future studies, the Forsyth team envisions a simple saliva test that could be administered by dental techn...

"Among the most plausible explanations is that the hollow jaw was a sound-producing device." The animals, he added, may have used the chamber to produce sounds as part of their co...

New understanding of parasite cell structures may provide treatments for serious tropical diseases

... the trypanosome transfers from the mid-gut to the salivary glands where it enters the human bloodstream when the fly bites. "We found that putting these cells under stress similar to that initially encountered by the trypanosome inside the fly caused the parasites to cleave free GPIs," said Mensa-Wilmot, "an...
