the use of donated embryos has offered hope for infertile couples who have no other means to have children. in iran, fertility centers use fertile couples as embryo donors. in this paper, the advantages and disadvantages of this procedure will be discussed. we conclude that embryo-donation should be performed with frozen embryos thus preventing healthy donors from being harmed by fertility drug...

Cryogenic x-ray photoelectron spectroscopy was used to analyze the cell envelope of intact and hydrated Gram-negative bacteria species Pseudomonas fluorescens. We a reference strain, DSM50090, from German microbial culture collection, which we previously have suggested would function well as strain for future XPS analyses bacteria. Bacteria were grown on nutrient agar plates at room temperature...

BackgroundThe number of frozen Embryo transfers (FET) in invitro fertilization cycles (IVF) is increasing and has already surpassed numbers fresh stimulated IVF cycles. Increasing elective single ETs are also resulting more embryos available for subsequent FET Most commonly, medicated or hormone supplemented (HC) which the endometrium prepared by exogenous estrogen progesterone following pituit...

We introduce a mathematical setup for charge transport in quantum pumps connected to a number of external leads. It is proved that under rather general assumption on the Hamiltonian describing the system, in the adiabatic limit the current through the pump is given by a formula of Büttiker, Prêtre, and Thomas, relating it to the frozen S-matrix and its time derivative.

A 30-year-old man with Ewing sarcoma presented with an enlarging metastatic osseous lesion involving the T10 vertebral body. Percutaneous cryoablation was performed under CT guidance for local tumor control; immediately following, he developed paraplegia. Early and delayed cord imaging show cryoablation-related injury (figures 1 and 2). The procedure involves targeted freezing of tissue to appr...

OBJECTIVE To evaluate DNA fragmentation in the oocyte of primordial and primary follicles and morphology of these follicles after freezing and thawing of ovarian cortex in sheep using two freezing protocols. DESIGN Fragmentation of DNA was evaluated by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling (TUNEL) technique. SETTING Fertility clinic in a large univ...

in this study, ice-glazing process of frozen shrimp by chitosan was applied to protect the frozen shrimp from undesirable chemical and physical changes. the effects of 2% chitosan solution glazing on quality of whole, raw and cooked (without head, tail and shell) shrimps stored at -18±2ºc for 6 months were investigated and compared with water glazing, sodium metabisulfite treatment control. gla...
