Why do eyelids sag with age? UCLA study answers mystery
Many theories have sought to explain what causes the baggy lower eyelids that come with aging, but UCLA researchers have now found that fat expansion in the eye socket is the primary culprit.

Java gives caffeine-naive a boost, too
New research from the University of Alberta in Edmonton, Canada, shows that-for women-the caffeine advantage is indeed everything it's cracked up to be. Females who don't drink coffee can get just as much of a caffeine boost as those who sip it regularly, according to a study in the latest edition of Nutrition Research.

Chronic stress alters our genetic immune response
Most people would agree that stress increases your risk for illness and this is particularly true for severe long-term stresses, such as caring for a family member with a chronic medical illness.

Study of islands reveals surprising extinction results
It's no secret that humans are having a huge impact on the life cycles of plants and animals. UC Santa Barbara's Steven D. Gaines and fellow researcher Dov Sax decided to test that theory by studying the world's far-flung islands.

Study shows PDE5 inhibitor more effective when used on demand in erectile dysfunction
European Urology, the official journal of the European Association of Urology will be featuring the article 'Effect of nightly versus on-demand vardenafil on recovery of erectile function in men following bilateral nerve-sparing radical prostatectomy' by F. Montorsi et al.in the October issue, showing for the first time that vardenafil, a PDE5 inhibitor, is more efficacious when used on-demand in men with erectile dysfunction, supporting a shift towards on-demand dosing with PDE5 inhibitors in this patient group.

Potential new targets for antidepressant medications
The news about antidepressant medications over the past several years has been mixed. The bad news from large multicenter studies such as STAR*D is that current antidepressant medications are effective, but not as effective as one might hope. Thus, there is a significant need for new treatment mechanisms for depression.

ABC-transporters expressed on endothelial cell membranes efflux anti-HIV drugs
Researchers at Tulane University Medical Center in New Orleans (USA) have discovered that drug-efflux pumps, belonging to the ATP-binding cassette (ABC) transporter family, are constitutively expressed on vascular endothelial cells.

Satisfaction and regret after radical prostatectomy procedures studied
Studies have shown that approximately 16% of patients with localised prostate cancer regret their treatment choice. European Urology, the official journal of the European Association of Urology, will be publishing an article by J.W. Moul et al. comparing differences in satisfaction and regret between patients who underwent open retropubic radical prostatectomy and robot-assisted laparoscopic radical prostatectomy.

Stick with simple antibiotics for pneumonia to avoid super bugs, says researcher
Australian hospitals should avoid prescribing expensive broad-spectrum antibiotics for pneumonia to avoid the development of more drug-resistant super bugs, according to a University of Melbourne study.

Bone parts don't add up to conclusion of Palauan dwarfs
Misinterpreted fragments of leg bones, teeth and brow ridges found in Palau appear to be an archaeologist's undoing, according to researchers at three institutions. They say that the so-called dwarfs of these Micronesian islands actually were modern, normal-sized hunters and gatherers.

Findings challenge common practice regarding glucose control for critically ill patients
An analysis of randomized trials indicates that for critically ill adults, tight glucose control is not associated with a significantly reduced risk of death in the hospital, but is associated with an increased risk of hypoglycemia, calling into question the recommendation by many professional societies for tight glucose control for these patients.

Global survey highlights need for cancer prevention campaigns to correct misbeliefs
Many people hold mistaken beliefs about what causes cancer, tending to inflate the threat from environmental factors that have relatively little impact while minimizing the hazards of behaviours well established as cancer risk factors, according to the first global survey on the topic.

Consumption of nuts, corn or popcorn not associated with increased risk of diverticulosis in men
Contrary to a common recommendation to avoid eating popcorn, nuts and corn to prevent diverticular complications, a large prospective study of men indicates that the consumption of these foods does not increase the risk of diverticulosis or diverticular complications, according to a study in the August 27 issue of JAMA.
