The effects of feeding a choline-deficient (CD) or a choline-supplemented diet upon the early stages of DLethionine carcinogenesis in rat liver were investigated. Low levels of ou-ethionine (0.05 and 0.10%) when fed with a CD diet were found to induce within 4 weeks a massive proliferation of oval cells without significant cell necrosis or presence of inflammatory cell infiltrates. The same lev...

Crossed-affinity immunoelectrophoresis of alpha-fetoprotein in amniotic fluid from 135 normal and 39 abnormal pregnancies (mainly neural-tube defects) was performed with a lectin, agglutinin from Lens culinaris. Results were compared with findings reported for another lectin, concanavalin A. Three fractions of alpha-fetoprotein were obtained by reaction with Lens cu/mans agglutinin. The most we...

BACKGROUND Considering the effect of preterm delivery in morbidity and mortality of newborns, its precaution and prevention is so important. OBJECTIVE To investigate the association between second trimester maternal serum biomarkers (Human Chorionic Gonadotropin, Alpha-fetoprotein, Non-conjugated estrogen, Inhibin A) and pre-term delivery. MATERIALS AND METHODS This is a historical cohort s...

We report one case of yolk sac tumor of the ear and review the literature. The patient was a 9-month boy who scratched his right ear repeatedly one month ago. Computed tomography scan showed an irregular elongated mass image measuring 42×16 mm was found in the right external auditory canal. The tumor was located underneath of the epidermis with ulceration. Mild or moderate atypical round or ova...

Objective: To investigate the differences in levels of Alanine Aminotransferase (ALT), HBV-DNA and Alpha-Fetoprotein (AFP) in serum between patients with different clinical types of Chronic Hepatitis B

Background and Aims: Human adipose tissue-derived stem cells (hASCs) are considered as an attractive source of regenerative stem cells, mainly because of their higher proliferation rate, more accessibility and hepatocyte like properties as compared to mesenchymal stem cells isolated from other tissues. Numerous studies have described the beneficial use of adipose tissue-derived stem cells for g...
