After Wearing A Cast Women Are Slower Than Men To Recover Their Muscle Strength

SOURCE:  Medical News Today

DATE:  September 25, 2008

EXCERPT:  "Researchers examined immobilized volunteers for a period of three weeks. They  determined that while men were able to regain 99% of their strength within a week of removing the cast, women's strength was still 30% lower when compared to before the cast was applied. These finding may have implications for the treatment of fractures based on gender lines.  The study is believed to be the first report of sex-differences in muscle strength restoration following disuse."  more

Osteoporosis And Bone Fractures: Thin Men More Vulnerable Than Older Men

SOURCE: Medical News Today

DATE:  September 21, 2008

EXCERPT: "Obesity and weight increase leads to an increased risk of many chronic diseases, and the advice is therefore to maintain a stable healthy weight. Now, research shows that there may be disadvantages to being thin. Men who have low weight in middle age and who reduce their weight, increase the chance of osteoporosis and fracture."   more

Hormone Cream Smoothes Skin Not Damaged by Sun CME (with audio)

SOURCE: MedPage Today

DATE:  September 15, 2008

EXCERPT: "Estradiol cream stimulated collagen production which smoothed wrinkled skin in elderly women, but only in areas that had not been exposed to the sun, researchers here reported. ...  And the effect of estradiol appeared to be gender-specific. For example, although men did have a benefit, it was less than the response observed in women."    more

Gender Differences In Experience Of Rheumatism

SOURCE: Medical News Today

DATE:  September 14, 2005

EXCERPT: "Rheumatoid arthritis is often a more painful experience for women than it is for men, even though the visible symptoms are the same. Scientists are now saying that doctors should take more account of these subjective differences when assessing the need for medication. This and other findings are being presented at a congress currently in progress on gender medicine arranged by Karolinska Institutet."  more

Male-Specific Neurons Directly Linked To Gender-Specific Behaviors

SOURCE:  Medical News Today

DATE:  September 13, 2008

EXCERPT: "New research identifies a few critical neurons that initiate sex-specific behaviors in fruit flies and, when masculinized, can elicit male-typical courtship behaviors from females. The study, published by Cell Press in the journal Neuron, demonstrates a direct link between sexual dimorphism in the brain and gender differences in behavior."   more

Walk This Way? Masculine Motion Seems To Come At You, While Females Walk Away

SOURCE: Medical News Today

DATE:  September 9, 2008

EXCERPT:  "You can tell a lot about people from the way they move alone: their gender, age, and even their mood, earlier studies have shown. Now, researchers have found that observers perceive masculine motion as coming toward them, while a characteristically feminine walk looks like it's headed the other way. ....  Their results showed that walking male figures did indeed appear to face toward you. Female figures, on the other hand, seemed as though they faced away. The results are the first to show a link between the perception of gender from biological motion cues and the perception of orientation.  That same pattern emerged regardless of the gender of the person watching, a finding that the author considers an important clue about the behavior."   more

Premature Children Four Times More Likely To Have Behavioural Disorders

SOURCE:  Medical News Today

DATE:  September 9, 2008

EXCERPT:  "Children born prematurely are four times more likely to have emotional problems or behavioural disorders, according to research   ....  They highlighted a distinction between genders in the pre-term group. Boys born prematurely showed a higher degree of behaviour problems, such as ADHD, and girls experienced more internalising disorders such as anxiety and depression.  The study also showed that extremely pre-term boys were more vulnerable to behavioural problems, and they had a greater impact on parents and teachers than extremely pre-term girls."  more
