Doctors may have found secretive new organs in the center of your head By Katherine J. Wu The New York Times Oct 20, at AM After millenniums of prostate cancer research centre address slicing and dicing, it might seem as though scientists have figured out human anatomy.

A few dozen organs, a couple hundred bones and connective tissue to tie it all together. But despite centuries of scrutiny, the body is still capable of Italok prosztatitis scientists. Advertisement A team of researchers in the Netherlands has discovered what may be a set of previously unidentified organs: a pair of large salivary glands, lurking in the nook where the nasal cavity meets the throat.

If the findings are confirmed, this hidden wellspring of spit could mark the first identification of its kind in about three centuries. Any modern anatomy book will show just three major types of salivary glands: one set near the prostate cancer research centre address, another below the jaw and another under the tongue.

Matthijs Valstar, a surgeon and researcher at the Netherlands Cancer Institute and an author on the study, published last month in the journal Radiotherapy and Oncology. Advertisement The study was small, and examined a limited patient population, said Dr.

But the structures are important to researchers and doctors who deal in oncology. It lubricates the mouth, making it easier to speak and swallow.

It ferries the tasty chemicals in food to the microscopic cells that can sense them. It even comes imbued with crude healing powers, waging war against germs and speeding the closure of wounds.

Doctors take numerous precautions to avoid damaging the glands when administering radiation therapy, which can, with a single misdirected zap, permanently prosztata gyulladas oka the delicate tissues. While perusing a set of scans from a machine that could visualize tissues in high detail, the researchers noticed two unfamiliar structures dead center in the head: a duo of flat, spindly glands, a couple inches in length, draped discreetly over the tubes that connect the ears to the throat.

Puzzled by the images, they dissected tissue from two cadavers and found that the glands bore similarities to known salivary glands that sit below the tongue. The new glands were also hooked up to large draining ducts — a hint that they were funneling fluid from one place to another.

They are more petite and tougher to find through imaging or scanning than their heftier cousins. Fitzhugh and Mowery were slightly more persuaded, but both called for more data.

Neonatal brain damage Abstract A specialized neurogenic niche along the ventricles accumulates millions of progenitor cells in the developing brain. After mitosis, fate-committed daughter cells delaminate from this germinative zone. Considering the high number of cell divisions and delaminations taking place during embryonic development, brain malformations caused by ectopic proliferation of misplaced progenitor cells are relatively rare. Here, we report that a process we term developmental anoikis distinguishes the pathological detachment of progenitor cells from the normal delamination of daughter neuroblasts in the developing mouse neocortex.

The original group examined by the researchers was made up entirely of people with prostate or urethral gland cancer, and included only one woman among subjects. The imaging techniques used in the study were also specifically tailored to hunt for tumorous growths in this patient population.

Supplementary Fig. GUID: BB30BFDA3EE-B0F5B2BB8D82 Abstract Various natural agents, including grape seed extract GSEhave shown considerable chemopreventive and anti-cancer efficacy against different cancers in pre-clinical studies; however, their specific protein targets are largely unknown and thus, their clinical usefulness is marred by limited scientific evidences about their direct cellular targets. Accordingly, herein, employing, for the first time, the recently developed drug affinity responsive target stability DARTS technique, we aimed to profile the potential protein targets of GSE in human colorectal cancer CRC cells. Unlike other methods, which can cause chemical alteration of the drug components to allow for detection, this approach relies on the fact that a drug bound protein may become less susceptible to proteolysis and hence the enriched proteins can be detected by Mass Spectroscopy methods.

It may be worth widening these experiments to include a new group of people, using different methods, she said.
