Background There are several indications of human female gamete cryostorage including sub-fertile and fertile patients. But our focus will be in women at risk of losing their reproductive function caused by oncologycal treatments or premature ovarian failure that could benefit greatly from this practice. Fertile women may take advantage of this technology to electively delay childbearing. The o...

We build high order numerical methods for solving diierential equations by applying extrapolation techniques to a Symplectic Integrator of order 2n. We show that, in general, the qualitative properties are preserved at least up to order 4n + 1: This new procedure produces much more eecient methods than those obtained using the Yoshida composition technique.

in the present article, a numerical method is proposed for the numerical solution of thekdv equation by using a new approach by combining cubic b-spline functions. in this paper we convert the kdv equation to system of two equations. the method is shown to be unconditionally stable using von-neumann technique. to test accuracy the error norms2l, ∞l are computed. three invariants of motion are p...

this study aimed to evaluate freeze-dried sera as an alternative to non-freeze dried for detection of anti-leishmania infantum antibodies over the course of 11 months using the direct agglutination test (dat).altogether, 60 serum samples (30 from humans and 30 from dogs) were collected from various geographical locations in iran. all the collected sera were pooled and each pooled serum sample c...

background: recent advances in cancer treatment have resulted in an increased number of cancer survivors. fertility might be impaired by cancer itself or through gonadal damage as a consequence of radio-chemotherapy. damages to reproductive organs are seen in minimally upto 30% of cancer patients. the aim of the present study was evaluate the attitude of iranian oncologists toward fertility pre...

in spite of the technologies developed during the last decade, the level of food loss is still high and is reported in many countries. according to the united nations, more than 30 per cent of the mortality rate world-wide is caused by alimentary diseases. the desire of most countries to make food safer for consumption requires better food preservation and production techniques. in this regard,...

The purpose of this study is to investigate the role of education and economic status of women in promoting the culture of environmental protection (Case study of employed and unemployed women between 30-45 years old in Gilane Gharb). The statistical population includes all employed and unemployed women. A simple random sampling method and a sample size of 352 people were obtained based on Coch...

Allografts eliminate the disadvantages associated with autografts and synthetic scaffolds but are associated with a disease-transmission risk. Therefore, allograft sterilisation is crucial. We aimed to determine whether polyvinylpyrrolidone-iodine (PVP-I) can be used for sterilisation and as a new wet-preservation method. PVP-I-sterilised and preserved allografts demonstrated improved mechanica...
