question:
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.
answer:
yes


question:
Question: Do infant and young child feeding practices differ by ethnicity of Vietnamese mothers?
Answer: Breastfeeding practices were suboptimal and differed by ethnicity, which suggests need for tailored interventions at multiple levels to address ethnic-specific challenges and norms. Complementary feeding practices were less optimal among ethnic minorities compared to Kinh, which suggests need for broad intervention including improved food availability, accessibility, and security.
answer:
yes


question:
Question: Do drosera rotundifolia and Drosera tokaiensis suppress the activation of HMC-1 human mast cells?
Answer: Drosera rotundifolia and Drosera tokaiensis suppressed activation of HMC-1 cells induced by aTc-m. Since the Drosera tokaiensis fraction was more effective than the traditionally used Drosera rotundifolia, Drosera tokaiensis is a likely substitute as a source of Droserae Herba.
answer:

yes
