[Q]: Question: Is the G-308A variant of the Tumor Necrosis Factor-alpha ( TNF-alpha ) gene associated with obesity , insulin resistance and body fat distribution?
Answer: Our study did not detect any significant association of the G-308A TNFalpha polymorphism with obesity or with its clinical and metabolic abnormalities in this population. Our data suggests that, in our population, the G-308A TNFalpha polymorphism is unlikely to play a major role in the pathogenesis of these conditions.
[A]: no


[Q]: Question: Does semen treatment with progesterone and/or acetyl-L-carnitine improve sperm motility or membrane damage after cryopreservation-thawing?
Answer: Neither progesterone nor acetyl-L-carnitine seemed to prevent cryodamage assessed by motility changes or membrane integrity in human spermatozoa of subfertile men. Annexin V binding, a reflection of membrane translocation of phosphatidylserine, provided more distinct information about postfreezing membrane integrity changes than eosin-Y staining.
[A]:
no
