The main dietary sources of selenium are plant foods grown in selenium-rich soils and animals who graze on such plants.
According to Eurekalert:
“The researchers noted a significant protective effect of selenium, mainly among women, which they believe may result from gender-specific differences in the mineral’s accumulation and excretion in women.”
Men who have been diagnosed with prostate cancer and need to have a gland surgically removed may suffer some temporary nerve damage. Complications of this major nerve could lead to more health concerns, including the killing of healthy cells in the penis, as well as erectile dysfunction.

However, researchers have discovered a protein that could speed up recovery of this complication. Using rats, the team of investigators administered sonic hedgehog, the beneficial protein, into the animals, using a gel that contains a high amount of nutrient.
The team of investigators discovered that the nerve regenerated twice as fast compared to if it healed on its own. This could lead to further research that may also help in treating peripheral nerves in the face that were damaged from certain types of cancer.
Successful studies may lead to improving male patients’ lives after surgery “because men are being diagnosed at a younger age and live longer due to improved cancer therapies,” said Carol Podlasek, assistant professor of urology at Northwestern University’s Feinburg School of Medicine.
These results may benefit prostate cancer patients for a more effective, natural treatment for the illness, as a recent report states. Other non-surgical procedures for these health complications have not been successful for the majority of experimental trial participants.
How many trips a night do you make to the bathroom?
If you have prostate problems, you understand this question all too well. Can anything improve your frequent, painful urination? These guys found something that works:
“Since taking (this natural remedy), I have gone several nights without getting up to go to the bathroom.” —Walter B., California
“I used to get up eight times a night to pee. So far, I’m down to four times a night. This is a vast improvement.” —Ed B., Oklahoma
“I have reduced the night trips to one in my seven-hour sleep period.” —Robert S., Montana
In what could lead to a major advance in the treatment of prostate cancer, scientists now know exactly why polyphenols in red wine and green tea inhibit cancer growth. This new discovery explains how antioxidants in red wine and green tea produce a combined effect to disrupt an important cell signaling pathway necessary for prostate cancer growth. This finding is important because it may lead to the development of, or improve current treatments that could stop or slow cancer progression.
“Not only does SphK1/S1P signaling pathway play a role in prostate cancer, but it also plays a role in other cancers, such as colon cancer, breast cancer, and gastric cancers,” said Gerald Weissmann, editor-in-chief of The FASEB Journal. “Even if future studies show that drinking red wine and green tea isn’t as effective in humans as we hope, knowing that the compounds in those drinks disrupt this pathway is an important step toward developing drugs that hit the same target.”
Scientists conducted in vitro experiments which showed that the inhibition of the sphingosine kinase-1/sphingosine 1-phosphate (SphK1/S1P) pathway was essential for green tea and wine polyphenols to kill prostate cancer cells. Next, mice genetically altered to develop a human prostate cancer tumor were either treated or not treated with green tea and wine polyphenols. The treated mice showed reduced tumor growth as a result of the inhibited SphK1/S1P pathway. To mimic the preventive effects of polyphenols, another experiment used three groups of mice given drinking water, drinking water with a green tea compound known as EGCg, or drinking water with a different green tea compound, polyphenon E. Human prostate cancer cells were implanted in the mice and results showed a dramatic decrease in tumor size in the mice drinking the EGCg or polyphenon E mixtures.
“The profound impact that the antioxidants in red wine and green tea have on our bodies is more than anyone would have dreamt just 25 years ago,” Weissmann added. “As long as they are taken in moderation, all signs show that red wine and green tea may be ranked among the most potent ‘health foods’ we know.”
What happens when the test is performed?
In most cases, you lie on your side with your knees bent up to your chest. An ultrasound machine’s sensor-a short rod about the width around of two fingers-is covered with a condom and clear jelly and gently inserted into your rectum. You may feel some pressure similar to the sensation before a bowel movement. Once the sensor is in place, an image of your prostate appears on a video screen.
The ultrasound sensor surveys the whole prostate gland and pinpoints specific areas for biopsy. Then the doctor removes this ultrasound sensor and replaces it with a slightly smaller one. In addition to generating an ultrasound image, the smaller sensor has a small tube on its side called a needle guide. Your doctor points the needle guide at specific parts of your prostate. The guide releases a spring-loaded needle to take biopsies from different parts of the prostate. The spring-loading allows this needle to move into and out of the prostate very quickly. You are likely to feel some discomfort from each biopsy, but because the needle moves so quickly, any pain lasts only for a second at a time. Doctors usually collect multiple samples.Your doctor will probably give you antibiotics at the end of this procedure to prevent infection.
What risks are there from the test?
Many people have some blood in their urine or stool for a day or two after the biopsy. The only significant risk is the possibility of an infection in the prostate, but antibiotics can help prevent this.
Must you do anything special after the test is over?
Call your doctor if you develop a fever.
How long is it before the result of the test is known?
A pathologist will examine the biopsies under a microscope for cancer. This process usually requires several days.
