Relationship between polymorphisms in the FAS/FASL death receptor system and progression of low-grade precursor lesions infected with high-risk human papilloma virus.

Squamous intraepithelial lesions (SIL) and cervical cancer are primary due to suboptimal immune response against human papillomavirus (HPV). The FASL/FAS system is a trigger of extrinsic pathway apoptosis. The distribution of polymorphisms rs1800682 (-670 A > G) FAS and rs763110 (-844C > T) FASL was studied in cervical smears from 372 females (182 with stable or regressed low-grade SIL (LSIL) (groupI) and a group of 190 high-grade SIL (HSIL) (groupII).

Cutaneous endometriosis: Presentation of 33 cases and literature review.

Objective: Cutaneous endometriosis is a rare condition that usually affects the abdominal wall in women with a history of open abdominal surgery. It has a characteristic clinical picture of a mass and pain associated with menstruation. The diagnosis is difficult on being an uncommon and little known condition.

Characterization of glycoside residues of porcine zona pellucida and ooplasm during follicular development and atresia.

The glycoside residues (glycoconjugates, GC) of the zona pellucida (ZP) glycoproteins are important during the first phases of fecundation. Our aim in this work was to determine the lectin affinity pattern of porcine ZP in order to analyze the changes that take place during: (a) preantral folliculogenesis, (b) the follicular atresia process, and (c) antral growth. Several prepubertal and adult pig ovaries and different sized antral follicles were used.

Proliferation and apoptosis of spermatogonia in postpuberal boar (Sus domesticus) testes with spontaneous unilateral and bilateral abdominal cryptorchidism.

Cryptorchidism is a frequent male sexual disorder in mammals, which affects the histology of the tunica propria, interstitial tissue, blood vessels, seminiferous epithelium and testis functioning. In this paper, proliferation and apoptosis were examined in the seminiferous epithelium of both testes from unaffected boars and from boars suffering unilateral and bilateral cryptorchidism. In germ cells, proliferation was studied using the immunohistochemical PCNA technique, and apoptosis was analysed by in situ TUNEL labelling.
