In a step toward using human saliva to tell whether those stiff joints, memory lapses, and other telltale signs of aging are normal or red flags for disease, scientists are describing how the protein content of women's saliva change with advancing age. The discovery could lead to a simple, noninvasive test for better diagnosing and treating certain age-related diseases in women, they suggest in a report in ACS' Journal of Proteome Research, a monthly publication. These diseases include lupus,...

A harmless digestive enzyme evolved twice into a dangerous toxin in 2 unrelated species Biologists have shown that independent but similar molecular changes turned a harmless digestive enzyme into a toxin in two unrelated species -- a shrew and a lizard -- giving each a venomous bite. The work, described this week in the journal Current Biology by researchers at Harvard University, suggests that protein adaptation may be a highly predictable process, one that could eventually help discover...

Though usually considered a parasitic nuisance and a vector for numerous diseases, the tick may actually hold the key for curing skin, liver, and pancreatic cancers, according to new findings from Brazilian researchers. Proteins were found in the saliva of the common South American tick Amblyomma cajennense, which seems to have the ability to reduce and even completely expunge cancerous cells while leaving healthy cells unharmed. "This is a radical innovation," said Ana Marisa...

Biopsies could soon be a thing of the past for detecting one of the deadliest types of cancers. Researchers have successfully identified markers of oral cancer in patients' saliva. Researchers at the University of California, Los Angeles, measured microRNA levels in 100 patients, half healthy and half with oral squamous cell carcinoma. A microRNA is a cell produced molecule that can simultaneously control activity and assess the behavior of multiple genes. Approximately 50 microRNAs were...

Researchers continue to add to the diagnostic alphabet of saliva by identifying the presence of at least 50 microRNAs that could aid in the detection of oral cancer, according to a report in Clinical Cancer Research, a journal of the American Association for Cancer Research."It is a Holy Grail of cancer detection to be able to measure the presence of a cancer without a biopsy, so it is very appealing to think that we could detect a cancer-specific marker in a patient's saliva," said Jennifer...

Women are more risk averse than men when it comes to making important financial decisions, which in turn can affect their career choices, U.S. researchers say. Paola Sapienza of the Kellogg School of Management at Northwestern University, Luigi Zingales of the University of Chicago Booth School of Business and Dario Maestripieri of the University of Chicago measured testosterone levels in saliva samples and markers of prenatal testosterone such as finger length from some 500 MBA students at...

Experts believe a simple saliva test could help spot which expectant mothers are likely to go into premature labor, BBC News reported.New mothers going into labor very early (before 34 weeks gestation) had abnormally low progesterone levels in their saliva, according to UK researchers. When this can be identified early, it would enable these women to be given steroids, which help in the development of the baby's lungs, preventing disability and death.Over 50,000 babies a year in the UK are...

An Israeli health report says the sharp rise of salivary gland cancer could be linked to the growing use of mobile phones. The report focused on oral cavity cancer in Israel from 1970 to 2006, Haaretz said Thursday. Researchers expressed concern over the increase of malignant growth in parotid glands, located under the ear, the report said. The report said from 1980 to 2002, the number of sufferers of this kind of cancer were approximately 25 each year but the number rose dramatically to 70...

ALEXANDRIA, Va., July 9 /PRNewswire-USNewswire/ -- The world-wide explosion of overweight people has been called an epidemic. The inflammatory nature of obesity is widely recognized. Could it really be an epidemic involving an infectious agent? In this climate of concern over the increasing prevalence of overweight conditions in our society, investigators have focused on the possible role of oral bacteria as a potential direct contributor to obesity. To investigate this possibility, the...

Salivary glands
2013-03-04 15:44:29

Salivary glands are glands that produce both saliva and the enzyme that turns starch into maltose, called amylase. Formation and Orientation There are five separate glands that make up the salivary gland system. First, the parotid gland is the largest of the salivary glands, secreting saliva through Stensen’s ducts to help with the breakdown of food in the mouth (mastication). The submandibular glands are situated beneath the lower jaws over the digastric muscles. This gland secretes...
