Objective(s): Umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  The objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. Materials and ...

introduction: as the ability to repair cartilage tissue in body is limited, finding a suitable method for cartilage regeneration has gained the attention of many scholars. for this purpose, scaffold structure and morphology, along with cell culture on it, can be a novel method to treat cartilage injuries, osteoarthritis. methods: in this study, polyhydroxybutyrate (phb) is selected as the scaff...

Background: It is not clear whether the use of volumetric peristaltic infusion pumps, affect the quality of the erythrocytes during packed cell transfusion or not. In the present study in vitro quality of red blood cells was assessed after using this type of infusion pumps in a prospective study. Materials and Methods: In this study 60 units of packed red cells were examined before and after p...

Background: Are dietary patterns, substantiated by biomarkers, associated with semen quality? Materials and Methods: In 161 men of subfertile couples undergoing in vitro fertilization treatment in a tertiary referral clinic in Rotterdam, the Netherlands, we assessed nutrient intakes and performed principal component factor analysis to identify dietary patterns. Total homocysteine (tHcy), folate...

Acid-citrate-dextrose (ACD) was introduced in 1947 as a nutrient-anticoagulant solution to preserve stored whole blood. A decade later, the introduction of citrate-phosphate-dextrose (CPD) resulted in the successful preservation of whole blood for 21 days. In 1978, added adenine and increased glucose concentration (CPDA-1) increased storage to 35 days. More recently, other solutions such as AS-...

Introduction The proper evaluation of the hemogram of any animal patient involves the determination of a total erythrocyte count [TRBC], packed cell volume [PCV], hemoglobin concentration [Hb], total white blood cell count [TWBC], white blood cell differential, and the evaluation of a stained peripheral blood film. The basic techniques used in mammalian hematology also apply to that of lower ve...

Recognition and application of blood group differences on human red cells permitted the development of safe procedures for blood transfusion. Blood group antigens are markers on surface-exposed red cell proteins or the sugar moiety of glycoproteins or glycolipids. Apart from their presumed biological function, some antigens have been identified as receptors for host/parasite interactions. Thus,...
