In this article we review the existing fertility preservation options for women diagnosed with Turner syndrome and provide practical guidelines for the practitioner. Turner syndrome is the most common sex chromosome abnormality in women, occurring in approximately 1 in 2500 live births. Women with Turner syndrome are at extremely high risk for primary ovarian insufficiency and infertility. Alth...
The treatment of fractures proximal and distal tibia is challenging, because the limited soft tissue envelope poor vascularity. best remains controversial it depends on fracture morphology, displacement comminution. Treatment options vary from closed reduction cast to open internal fixation with plate. Open plate can result in extensive dissection devitalization. We conducted a study management...
At the beginning of the 20th century, successful preservation methods for cells and tissues were developed with new insights into biology and physics. In nature, we have already seen interesting examples of biopreservation. For instance, species such as water-bears (e.g., Tardigrada) and distinct frog types (e.g., Rana sylvatica) can survive in extremely cold temperatures by replacing the water...
The ability to archive biological samples for subsequent nucleic acid analysis is essential for tissue specimens and forensic samples. FTA Card is a chemically treated filter paper designed for the collection and room temperature storage of biological samples for subsequent DNA analysis. Its usefulness for the preservation of biological samples for subsequent RNA analysis was tested. Here, we d...
Background: Oocyte, embryo and ovarian tissue cryopreservation are proposed for fertility preservation to cancer patients who hope to be mothers after getting rid of the disease. Materials and Methods: Embryo cryopreservation is not possible for unmarried single girls without sperm partner and oocyte retrieval is a long time procedure. Thus ovarian tissue cryopreservation is suggested for ferti...
the present study investigated the possibility of replacing salamon with modified shotor diluent (msd) and egg yolk (ey) with low density lipoprotein (ldl) for chilled storage of ram semen. good quality semen (>80% progressive forward motility (pfm) of sperm) from 3 fertile rams was collected using an artificial vagina and pooled for each experiment. low density lipoprotein was extracted from f...
background: environmental problems of the plastic materials used in food packaging and the demand for food quality improvements lead to the development of packaging in natural materials. edible films such as calcium alginate extend the shelf life by acting as a selective barrier against moisture and oxygen. the main objective of this study was to explore a calcium alginate based edible film to ...
background: in vitro maturation (ivm) of immature oocytes collected from ovary has been proposed for fertility preservation. in addition, quality of oocytes post ivm is one of the factors determining its developmental competence. by using the non-invasive polscope system, both meiotic spindle (ms) and zona pellucida (zp) can be assessed in living oocytes. objective: the aim was to investigate t...
