New research suggests that a compound abundant in the Mediterranean diet takes away cancer cells' "superpower" to escape death. By altering a very specific step in gene regulation, this compound essentially re-educates cancer cells into normal cells that die as scheduled. http://medicalxpress.com/news/2013-05-compound-mediterranean-diet-cancer-cells.html Cancer Mon, 20 May 2013 15:40:33 EST news288283224 (HealthDay)—There was no effect of intensive versus conventional insulin therapy during the Diabetes Control and Complications Trial (DCCT) on cardiac parameters as assessed by cardiac magnetic resonance (CMR) in the Epidemiology of Diabetes Interventions and Complications (EDIC) cohort (follow-up to the DCCT), but prior glycemic exposure had an impact on cardiac parameters, according to research published online March 21 in Diabetes. http://medicalxpress.com/news/2013-04-cardiac-function-unaffected-prior-intensive.html Diabetes Fri, 12 Apr 2013 12:59:21 EST news284990356 Scientists reported new evidence today that a component of egg whites—already popular as a substitute for whole eggs among health-conscious consumers concerned about cholesterol in the yolk—may have another beneficial effect in reducing blood pressure.

This is the conclusion reached by University of Twente psychologist Pascal Wilhelm (department of Instructional Technology) and three co-researchers after a study of 103 pupils at a secondary school in the Dutch province of Overijssel. The results of the study will be published in the journal Tijdschrift voor Psychiatrie. One particularly unusual aspect of the study is that three of the four researchers were still at school themselves at the time of the study. http://medicalxpress.com/news/2013-01-energy-youngsters-smarter.html Psychology & Psychiatry Thu, 10 Jan 2013 08:22:05 EST news277028512 Drinking three to four cups of coffee per day may help to prevent type 2 diabetes according to research highlighted in a session report published by the Institute for Scientific Information on Coffee (ISIC), a not-for-profit organisation devoted to the study and disclosure of science related to coffee and health. http://medicalxpress.com/news/2012-12-moderate-coffee-consumption-diabetes-percent.html Diabetes Tue, 04 Dec 2012 10:35:53 EST news273839741 A new study suggests that the common diabetes medication metformin may be considered for use in the prevention or treatment of ovarian cancer.

However, calorie restriction did extend certain aspects of health. The research, conducted by scientists at the National Institute on Aging (NIA) at the National Institutes of Health, is reported in the August 29, 2012 online issue of Nature. http://medicalxpress.com/news/2012-08-low-calorie-diet-prolong-life.html Medical research Wed, 29 Aug 2012 13:03:54 EST news265464228 The commonly-used epilepsy drug, valproic acid (VPA), can have a highly beneficial effect on some babies born with spinal muscular atrophy (SMA), the number one genetic killer during early infancy. But in about two-thirds of such cases it is either damaging or simply has no effect. Now, for the first time, researchers have found a way to identify which patients are likely to respond well to VPA prior to starting treatment. Their results have major implications, not just for SMA patients, but for other conditions treated with the drug such as migraine and epilepsy, and may even provide the conditions for turning VPA non-responders into responders, the researchers say. http://medicalxpress.com/news/2012-06-treatment-response-central-nervous-diseases.html Genetics Sat, 23 Jun 2012 06:17:25 EST news259651029 Women are less prone to cardiovascular disease then men; but this difference between the sexes becomes less marked after the menopause. This observation is behind a great deal of received wisdom, where oestrogen is assumed to have a beneficial effect on the heart and blood vessels. Today, new data seems to question these presuppositions. A study has been conducted by a team of Inserm researchers, directed by Pierre-Yves Scarabin (Inserm Unit 1018 "Centre for Epidemiology and Population Health Research"), on 6,000 women aged over 65; its results demonstrate, for the first time, that women with high levels of oestradiol in their blood are exposed to a greater risk of myocardial infarction or strokes. http://medicalxpress.com/news/2012-06-estrogen-cardiovascular-menopausal-women.html Cardiology Mon, 11 Jun 2012 11:14:08 EST news258631693 Statins prevent cancer and reduce death from all causes in heart transplant recipients.

Aquatic therapy has been shown to have a beneficial effect, and it is typically begun two weeks after surgery, after the wound has healed. According to a new study published in the Archives of Physical Medicine and Rehabilitation, beginning aquatic therapy just 6 days after TKA may lead to improved results, while delaying its onset an additional week may be more appropriate after a THA. http://medicalxpress.com/news/2011-12-aquatic-therapy-total-knee-arthroplasty.html Other Wed, 21 Dec 2011 04:40:01 EST news243664181 However, large-scale clinical trials have highlighted the beneficial effect of cardiac resynchronisation therapy (CRT) in the improvement of symptoms and reduction of mortality, and CRT is now recommended in the major European and American guidelines for the treatment and prevention of heart failure.(1) http://medicalxpress.com/news/2011-12-benefits-cardiac-resynchronisation-therapy-heart.html Cardiology Mon, 19 Dec 2011 05:10:01 EST news243492604 (Medical Xpress) -- A large study to investigate causes of common cancers in India is being carried out through a collaboration between Oxford University and 12 leading cancer centres in India. http://medicalxpress.com/news/2011-10-largest-cancer-india.html Cancer Wed, 26 Oct 2011 07:28:22 EST news238832744 Depending on the age of asthmatic children, on their exposure to molds or dampness in their bedroom, and on the severity of their asthma, vitamin C has greater or smaller beneficial effect against asthma, according to a study published in the Clinical and Translational Allergy. http://medicalxpress.com/news/2011-08-vitamin-beneficial-asthmatic-children.html Health Tue, 30 Aug 2011 10:47:46 EST news233920047 Moderate social drinking significantly reduces the risk of dementia and cognitive impairment, according to an analysis of 143 studies by Loyola University Chicago Stritch School of Medicine researchers. http://medicalxpress.com/news/2011-08-moderate-alzheimer-cognitive-impairment.html Addiction Tue, 16 Aug 2011 09:15:23 EST news232704904
