Background: The cryopreservation of human oocyte would make significant contribution to fertility treatments. It could also provide on alternative to embryo preservation for avoidance ethical problems. Embryo cryopreservation is now a successful procedure, but oocyte cryopreservation has poorer results. Materials and Methods: For retrieval of oocyte NMRI mouse were used. after administration of...

Somatic embryogenesis is a developmental process during which plant somatic cells, under in vitro conditions, produce embryogenic cells that develop into embryos. an efficient method clonal propagation of plants. Mature embryos were used as explant source for callus formation and the produced compact, healthy most mature induced callus. showed similar morphologically to their non-somatic counte...

Background The current study aimed to evaluate the effects of phosalone (PLN) as an organophosphate (OP) compound on testicular tissue, hormonal alterations and embryo development in rats. MaterialsAndMethods In this experimental study, we divided 18 mature Wistar rats into three groups-control, control-sham and test (n=6 per group). Animals in the test group received one-fourth the lethal dose...

Aim: The aim of this study was to determine the effect paternal age on miscarriage rates in couples undergoing vitro fertilization/intracytoplasmic sperm injection treatment cycles. Material and Methods: Patients were classified into two groups. group consisted patients whose pregnancy resulted a (n=73) control which had live singleton birth (n=256). Demographic characteristics, indications, du...

Immature, mature and endosperm-supported mature embryos of six triticale cultivars (BDMT-98-8S, Melez-2001, Mikham-2002, Presto, Tacettin Bey and Tatlicak-97) were cultured in vitro to compare the levels of callus induction and plant regeneration. Immature embryos, 15-18 days after anthesis, were aseptically excised and placed with the scutellum upwards on a callus culture medium consisting of ...

Background: Because of the problems of achieving to mature oocytes, abillity to deliver the oocytes to mature outside of ovaries was a big discovery that somewhat could reduce the risk of ART`s.Because of the low percentage of in vitro oocyte maturation, research for improving the IVM condition and increasing the oocyte maturation rate is to be continued. The aim of this research is the study o...

BACKGROUND: All-trans retinol is a biological antioxidantscavenging the ROS in the cell culture. OBJECTIVES: This studywas conducted to investigate the effect of all-trans retinol infertilization and culture medium on mouse embryo's developmentalcompetence. METHODS: This study was designed into twoexperiments. In the first experiment, in vitro mature oocytes wereco-cultured with sperm in fertil...

Pulsatilla cernua var. koreana seeds were harvested at six different dates between 16 days after flowering (DAF) (8 Apr.) and 43 DAF (5 May) in 2018 categorized into groups based on X-ray images. Germination tests performed without with 2 weeks of moist 5 °C treatment [cold stratification (CS)]. Seeds 38 (30 well-developed vegetative organs (embryo endosperm) as A B (seed seed B, respectively) ...

Quantitative phenotypic traits are influenced by genetic and environmental variables as well as the interaction between the two. Underlying genetic × environment interaction is the influence that the surrounding environment exerts on gene expression. Perturbation of gene expression by environmental factors manifests itself in alterations to gene co-expression networks and ultimately in phenotyp...
