question:
Question: Does production of infectious human immunodeficiency virus type 1 require depletion of APOBEC3G from virus-producing cells?
Answer: Our results suggest that Vif and APOBEC3G can be efficiently co-expressed. Thus, depletion of APOBEC3G from Vif expressing cells as suggested previously is not a universal property of Vif and thus is not imperative for the production of infectious virions.
answer:
no


question:
Question: Is lymphocyte inhibition compromised in mesenchymal stem cells from psoriatic skin?
Answer: This study demonstrated abnormalities in MSCs derived from psoriatic skin lesions. We suggest that the attenuated inhibitory effect on T-cell proliferation might be one of the pathogenic mechanisms of psoriasis.
answer:
yes


question:
Question: Do digit ratios serve as anatomical evidence of prenatal androgen exposure in clinical phenotypes of polycystic ovary syndrome?
Answer: Women with PCOS do not demonstrate finger length patterns that are consistent with increased prenatal androgen exposure. These findings do not preclude a role for prenatal androgens in the development of PCOS; however, low 2D:4D are not a characteristic of PCOS.
answer:

no
