Question: Are cD44-9v and CD44-10v potential molecular markers for squamous cell carcinoma of the vulva?
Answer: Our findings warrant larger multi-institutional studies to determine the potential of CD44-9v and CD44-10v as molecular markers of disease recurrence in vulvar carcinoma. We propose to test the use of anti-CD44-9v monoclonal antibody for radioimmunoimaging of occult LN metastases.
yes

Question: Is resistive heating more effective than metallic-foil insulation in an experimental model of accidental hypothermia : A randomized controlled trial?
Answer: Resistive heating more than doubles the rewarming rate compared with that produced by reflective metal foil and does so without producing an afterdrop. It is therefore likely to be useful in the prehospital setting.
yes
