Establishment and characterization of a human parathyroid carcinoma derived cell line.

Parathyroid carcinoma is a rare neoplasia associated with PTH-dependent hypercalcaemia. It is infrequent in primary hyperparathyroidism (HPT) and very rarely associated with uremic HPT. A continuous cell line named Pt.

Identification of displaced endometrial glands and embryonic duct remnants in female fetal reproductive tract: possible pathogenetic role in endometriotic and pelvic neoplastic processes.

Background: Recent findings strongly promoted the hypothesis that common pelvic gynecological diseases including endometriosis and ovarian neoplasia may develop de novo from ectopic endometrial-like glands and/or embryonic epithelial remnants. To verify the frequency, the anatomical localization and the phenotype of misplaced endometrial tissue along the fetal female reproductive tract, histological and immunohistochemical analyses of uteri, fallopian tubes, and uterosacral ligaments were performed.

Methods: Reproductive organs were collected from seven female fetuses at autopsy, five of them from gestational ages between 18 and 26 weeks and two fetuses with gestational ages of 33 and 36 weeks deceased of placental anomalies.

A low-cost implantable near-infrared imaging system of spinal cord activity in the cat.

A low-cost device using diffuse optical imaging (DOI) for measuring in vivo hemodynamic changes in the spinal cord has been developed. The proposed system is aimed at monitoring for the first time real-time hemodynamic changes associated with intraspinal rhythmic motor activity monitored by electroneurogram (ENG) evoked in paralyzed cats (fictive locomotion). The device contains the emitting and collecting probes within a saddle that fits over a vertebra and has been developed with discrete component circuits.
