Decreased Natural Killer Cell Activity in Women with Endometriosis
Gynecologic and obstetric investigation ·doi:10.1159/000292720

Natural killer (NK) cell activity is characterized by the spontaneous capacity of lymphoid cells derived from nonimmunized hosts to recognize and lyse certain tumor cell lines, virus-infected cells and transplanted tumor cell lines. Endomet…

Effects of aging on ovarian fecundity in terms of the incidence of apoptotic granulosa cells.
Journal of assisted reproduction and genetics ·doi:10.1023/a:1009422323306

PurposeThe objective was to determine the effects of women's age on the ovarian fecundity as assessed by the incidence of apoptotic granulosa cells.MethodsTwenty-eight normo-ovulatory women underwent ovulation induction for standard IVF. Th…

Effects of controlled ovarian hyperstimulation on oocyte quality in terms of the incidence of apoptotic granulosa cells.
Journal of assisted reproduction and genetics ·doi:10.1023/a:1026439409584

PurposeThe aim was to investigate which ovarian hyperstimulation protocol performed in the same patients causes development of oocytes of good quality.MethodsTwenty normo-ovulatory women underwent three different controlled ovarian hypersti…

Hyaluronic acid inhibits apoptosis in granulosa cells via CD44.
Journal of assisted reproduction and genetics ·doi:10.1023/a:1009470206468

PurposeThis study was designed to examine whether hyaluronic acid (HA) inhibits apoptosis in cumulus and mural granulosa cells and to examine whether this effect of HA was mediated through CD44.MethodsMural and cumulus granulosa cells were …

Expression of CD44 in human cumulus and mural granulosa cells of individual patients in in-vitro fertilization programmes
Molecular human reproduction ·doi:10.1093/molehr/5.1.22

CD44 is a polymorphic and polyfunctional transmembrane glycoprotein widely expressed in many types of cells. Here, the expression of this protein on human membrana granulosa was studied by two techniques. Using confocal laser scanning micro…
