Background Transfer of micro-Injected oocytes into fallopian tubes is an alternative procedure for IVF-ET with a similar success rate. This could be either done immediately after ovum pick-up microinjected oocytes intrafallopian transfer (MIFT) or after a time interval zygote intrafallopian transfer (ZIFT). This study was designed to compare the outcomes of the two procedures. MaterialsAndMetho...

The method here described, which we have been using for some time in routine work, is a modification of the micro-method of May and others (1947), in which dilutions of the patient's serum are added to phenol-red-serum water on waxed slides, and incubated in capillary tubes. The dilutions of patient's serum and their addition to the medium are performed on a waxed glass plate which is incubated...

UK Biobank required a cryogenic facility to store, in vapour phase, a minimum of 5 000 000 1.2 ml capacity micro-tubes held in racks of 96 tubes below -180 degrees C for a 20 year period. The archive would be housed in a 900 m(2) industrial unit remote from the main laboratory area that would be generally unmanned and would require a complete cryogenic infrastructure. A commercial supplier was ...

In the present work, forced convection heat transfer of slip flow in porous micro-tubes with local thermal non-equilibrium between the gas and the solid matrix is investigated numerically. For this purpose, the flow is considered hydrodynamically developed but thermally developing. The Darcy-Brinkman-Forchheimer model in conjunction with separate energy equations for the gas and the solid matri...

Increasing material’s strength is of particular importance. Improving material’s mechanical properties such as strength could reduce the size and weight of the structure. The size and weight of the structure are among the effective parameters in design. Since the past a variety of methods have been developed to increase the strength of metals that are capable of increasing metals’ strength to a...

Isomerisation kinetics of the 9c11t and 10t12c Conjugated Linoleic Acids (CLA) in triaclglycerols at isothermal conditions (250, 280 and 325 o C) has been studied by infrared spectroscopy. Fifteen micro liter portions of the glycerides were placed in micro glass ampoules and sealed under nitrogen. Several glass tubes containing the same triacylglycerols were then subjected to thermal treatment....

Dosing Valuable Substance Compound libraries are not only responsible for the storage of several thousand different substances but also for further distribution. Laboratory staff can identify potentially active compounds in the database for their individual experiments and order a small amount from stock. Thereafter, the substances need to be aliquoted into small final tubes. These compounds ar...

BACKGROUND In this study the concentration of lysozyme in blood plasma of Microtus agrestis, Clethrinomys glareolus, Apodemus sylvaticus, BK rats and outbred white mice before and after infection with culture forms of Trypanosoma microti, T, evotomys, T. grosi, T. lewisi and T. musculi respectively was measured. METHODS Blood samples of rodents, Microtus agrestis, Clethrionomys glareolus, Apo...

Scaffolds play a pivotal role in the tissue engineering paradigm by providing temporary structural support, guiding cells to grow, assisting the transport of essential nutrients and waste products, and facilitating the formation of functional tissues and organs. Single-walled carbon nanotubes (SWNTs), especially ultra-short SWNTs (US-tubes), have proven useful for reinforcing synthetic polymeri...
