Estudos para todos os gostos: Exercício físico e apetite sexual

Vários estudos na ligação seguinte alguns com resultados surpreendentes, outros nem por isso (como o que motiva o título desta notícia):

Citando:
"Exercise is meant to make us hot-blooded, but too much of it can sap our sex drive, a new study has found.

Research has tended to focus on how our sex drive benefits from regular exercise. Aside from the confidence-boost exercise gives us (and confidence leads to greater sexual satisfaction), there are the physiological effects. "
(...)
"it is not the first study to show the "negative impact" of endurance exercise and elite sport.

She says there are two reasons for this – the psychological and the physical. It is known that intense exercise can negatively impact testosterone (which affects both sex drive and sperm count), but Quirk adds:

"There's a parallel between immunological function and sexual interest and there is a negative effect – in elite sports and endurance athletes – on immunological function."

Quirk adds that moderate activity provides "a reasonable amount of benefit" but when we start pushing ourselves hard for extended periods of time, we become mentally and physically "spent".

"Sex will be very low on the list," she says. "

Mel de manuka, os chineses e a imunidade melhorada?

Ainda a ser estudado (originário da Nova Zelândia) mas uma loucura em termos de procura:

"(...) Molan discovered there was something special about manuka honey. It appears to have antibacterial properties, unlike other honeys in the world, and some studies suggested it could heal wounds and help boost the immune system. (Specifically, the antibacterial property found in other honeys comes from hydrogen peroxide, which is broken down quickly in the body, whereas the non-peroxide form found in manuka honey isn’t.)."

Parar a esclerose múltipla? - Estudo / Tratamento

http://www.bbc.com/news/health-36490315
Citando:
"The condition causes the immune system to attack the lining of nerves in the brain and spinal cord. Most patients are diagnosed in their 20s and 30s.
One existing treatment is for the immune system to be suppressed with chemotherapy and then stem cells are introduced to the patient's bloodstream - this procedure is known as an autologous haematopoietic stem cell transplant (HSCT).


(...)
But in this study, Canadian researchers went further - not just suppressing the immune system, but destroying it altogether.
It is then rebuilt with stem cells harvested from the patient's own blood which are at such an early stage, they have not developed the flaws that trigger MS.
The authors said that among the survivors, over a period of up to 13 years, there were no relapses and no new detectable disease activity."
(...) "1 person died".
