Dental pulp is a promising source of mesenchymal stem cells for use in cell therapy and regenerative medicine. Methods for storing stem cells with minimum compromise of cell viability, differentiation capacity and function should be developed for clinical and research applications. The aim of this study was to evaluate whether human dental pulp stem cells (hDPSCs) isolated and cryopreserved for...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
In the present study, cryopreservation of common carp (Cyprinus carpio) embryos was studied using a stepwise cooling protocol. Embryos at heartbeat stage were selected, placed in 15- ml plastic tubes and stored at -2 °C for 1, 7, 14, and 21 days in 2 different cryopreservation solutions: S1 (methanol + dimethyl sulfoxide + sucrose) and S2 (methanol + propylene glycol + sucrose). Embryo viabilit...
because of the importance of iranian rice germplasm and its application in the rice breeding programs and international genetic resources exchanges, some researches are necessary to preserve these valuable genetic resources. for this purpose, the cryopreservation of the biological samples in liquid nitrogen at -196 °c can be used. in this research, the cryopreservation of the zygotic embryos of...
OBJECTIVE Comparison of time intervals from diagnosis to chemotherapy between patients opting for embryo cryopreservation or ovarian tissue cryopreservation. STUDY DESIGN Retrospective analysis. SETTING University hospital in the Netherlands. PATIENTS AND METHODS Thirty-five female patients undergoing fertility preservation procedures before treatment with chemotherapy for cancer. Embryo ...
AIM To study the morphologic and cellular immunologic changes after homologous transplantation of the abdominal aorta in rats after programmed cryopreservation (-196 degrees). METHODS Abdominal aorta was harvested from anesthetized Spraque Dawley (SD) rats for cryopreservation (group B) or immediate implantation (group A). The survival rates and apoptotic rates of aortic endothelial cells (EC...
BACKGROUND The cause of valve allograft failure is most likely multifactorial and may include mechanical, immunological, and other factors. Cryopreservation of these valves is often used to extend storage times. However, there has been considerable confusion as to the effects of cryopreservation on valve durability. Our objective was to determine the effects of cryopreservation on histopatholog...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
