Prior to the World Health Organization's announcement of total eradication in 1977 [J. Am. Med. Assoc. 281 (1999) 1735], smallpox was a worldwide pathogen. Vaccinations were ceased in 1980 and now with a largely unprotected world population, smallpox is considered the ideal biowarfare agent [Antiviral Res. 57 (2002) 1]. Infection normally occurs after implantation of the virus on the oropharyng...
Infertility is a problem for couples throughout the world. One solution is surrogate motherhood. A typical surrogate mother contract involves three parties: a man and a woman who، as a couple، want to employ the services of a surrogate mother، and another woman who agrees to conceive a child through artificial insemination with the couples' embryo. Usually، in return for a sum of money، the sur...
Background: The practice of surrogacy is one of the most controversial procedures in infertility treatment. Despite increasing of using this technology in Iran, there are few practical data about surrogacy.There isn't any study assessing experiences of commissioning mothers about surrogate mother selection. Aim: The purpose of this study was exploring of commissioning mothers' experiences in se...
In this study, a novel system for the detection and quantification of organofluorophosphonates (OFP) has been developed by using an optical sensing polymeric membrane to detect the fluoride ions produced upon OFP hydrolysis. Diisopropyl fluorophosphate (DFP), a structural analogue of type G chemical warfare agents such as Sarin (GB) and Soman (GD), is used as the surrogate target analyte. An op...
Acetamide has been classified as a possible human carcinogen, but uncertainties exist about its levels in foods. This report presents evidence that thermal decomposition of N-acetylated sugars and amino acids in heated gas chromatograph injectors contributes to artifactual acetamide in milk and beef. An alternative gas chromatography/mass spectrometry protocol based on derivatization of acetami...
Quantitative targeted proteomics based approaches deploy state-of-the-art Liquid chromatography tandem mass spectrometry LC-MS technologies and are evolving as a complementary technique to standard ligand-binding based assays. Advancements in MS technology, which have augmented the specificity, selectivity and sensitivity limits of detection and freedom from antibody generation, have made it am...
When the contractual liability of surrogate mother against genetic parents was created that one correct and binding contract concluded between them and surrogate mother violate the created obligation of this contract. Majority of this obligation arises the agreement between them and other resource i.e. law and custom is silent. This violation causes the material and moral damage for genetic par...
Three antituberculosis medications are investigated in this work consist of rifampicin, isoniazid and pyrazinamide. The ultra violet (UV) spectra of these compounds are overlapped, thus use of suitable chemometric methods are helpful for simultaneous spectrophotometric determination of them. A generalized version of net analyte signal standard addition method (GNASSAM) was used for determinatio...
