Immunohistological and Elution Studies of the Human Placenta

A STUDY ON THE HEMOPOI ETIC ACTIVITY OF HUMAN PLACENTA IN VITRO, IN THE PRESENCE AND ABSENCE OF STIMULATORS AND INHIBITORS OF TRANSCRIPTION AND TRANSLATION

The hemopoietic activity of the human placenta was studied in vitrc under various conditions in order to assess the optimal conditions of protein synthesis and colony stimulating factor (CSF) production by this tissue. The hemopoietic activity of placental tissue was assayed by the semi -solid agar medium technique. In order to obtain maximum hemopoietic activity, various stimulators were ...

Immunohistochemical evaluation of lymphocyte types infiltrate into the canine seminomas

BACKGROUNDS: Seminoma is frequently observed in human and canine testes especially in cryptorchids. Canine and human seminomas are typically associated with leukocytic infiltration. OBJECTIVES: We aimed to identify the type of lymphocytes that infiltrate to seminomas. METHODS: Tumor infiltrating lymphocytes were evaluated by immunohistological techniques in 5 dogs with diffuse seminoma. Routine...

Human term placental cells: phenotype, properties and new avenues in regenerative medicine

The human placenta has long been the subject of scientific interest due to the important roles which it performs during pregnancy in sustaining the fetus and maintaining fetomaternal tolerance. More recently, however, researchers have begun to investigate the possibility that the placenta’s utility may extend beyond fetal development to act as a source of cells with clinically relevant properti...

Expression and Distribution of Calcium-Binding Protein S100P in Human Placenta during Pregnancy

High-Performance Liquid Chromatographic Determination of Rivastig-mine in Human Plasma for Application in Pharmacokinetic Studies

A simple and reproducible HPLC method with spectrophotometric detection was developed for determination of rivastigmine in human plasma. Liquid-liquid extraction of rivastigmine and donepezil (as internal standard) from plasma samples was performed with 1-butanol/n-hexane (2:98 v/v) in alkaline condition followed by back-extraction into diluted acetic acid. Chromatography was carried out using ...
