A recent study at Queen’s University has identified a possible cause for the loss of a tumour suppressor gene (known as PTEN) that can lead to the development of more aggressive forms of prostate cancer.
Researchers say that this discovery helps for a greater understanding of how aggressive prostate cancer develops because they now have some insight into the mechanism by which the PTEN gene is destroyed.
PTEN is one of a small class of tumor suppressor genes that closely regulates the growth of cells. When PTEN is altered or deleted in prostate cells, they lose the ability to make a protein that controls normal growth. Cells can then grow uncontrolled and can develop into a prostate cancer

New research by Australian scientists reveals that males who are exposed to high levels of testosterone before birth are twice as likely to experience delays in language development compared to females.

The research, published in Journal of Child Psychology and Psychiatry, focused on umbilical cord blood to explore the presence of testosterone when the language-related regions of a fetus’ brain are undergoing a critical period of growth.

Human papillomavirus, or HPV, has recently been linked to some types of head and neck cancer that are becoming more prominent in the United States, mostly among men. Patients infected with oral HPV type 16 have a 14 times greater risk of developing one of these cancers, which usually form on the tonsils and at the back of the tongue.
Acording to the study findings, Oral HPV infection is more common among men than women, explaining why men are more prone than women to develop an HPV related head and neck cancer.
The correlation between HPV and oral cancer was only established in 2007, so it is not well understood how to detect or prevent these cancers.

The study was presented at the Multidisciplinary Head and Neck Cancer Symposium, sponsored by AHNS, ASCO, ASTRO and SNM.

A new study finds that men are at higher risk than women for subtle problems with memory and thinking skills that often precede Alzheimer’s disease.

Reserchers say currently married people were at lower risk of mild cognitive impairment than those widowed, divorced or single. Also, having a high school or less education was also linked to greater risk, and the study found that the combination of being male without college education brought an “unexpectedly high risk” of impairment that did not involve memory loss.

Two studies at  Kansas State University, propose to help men make more informed diet decisions by studying foods and dietary supplements that may reduce the risk of prostate cancer.

 Both projects are in the early stages, and the team leader hopes that they can provide insight into ways that men can reduce their risk of prostate cancer.

Good news for men diagnosed with low-risk, localized prostate cancer. Results of a three-year international clinical trial show that being treated with the drug dutasteride (”Avodart”) delays disease progression and initiating active treatment, and also reduces anxiety.

Researchers say that using active surveillance plus dutasteride , patients can avoid aggressive treatment that can have a major impact on their quality of life, with risks of impotence and incontinence

A new Australian study has said if one wants to predict whether a baby is going to have a weight problem in the future, they must look at their dad.
The Australian study looked at the weights of eight- and nine-year-old children from two-parent families where one parent was obese.

The findings go against popularly held beliefs that mothers, who tend to spend more time with children than fathers as well as usually controlling food shopping and meals, have more influence over children’s weight.

A team of researchers from San Francisco has sayd that an artificial testicle that produces human sperm could help solve the problem of male infertility,

Researchers hope they can make such a “sperm-making biological machine”. It will be shaped like a cylindrical bag a few inches long and won’t be attached to the body.

It would have to be replaced after every cycle of sperm production, which takes 70 days.

It shouldn’t be confused with a non-sperm-producing prosthesis that is commonly used by men missing a testicle, which are filled with a saline solution.

A new study at the University of Melbourne has found An increase in body weight during a man’s adult life is associated with an increased risk of suffering an aggressive form of prostate cancer and of dying from it.
The study also found that having a high body mass throughout life was also associated with increased risk of aggressive prostate cancer.
The study has been published in the International Journal of Cancer

New research from Uppsala University, Sweden, shows that a specific brain region that contributes to a person’s appetite sensation is more activated in response to food images after one night of sleep loss than after one night of normal sleep.

 Poor sleep habits can therefore affect people’s risk of becoming overweight in the long run. The findings are published in the Journal of Clinical Endocrinology & Metabolism.
