background: it is important to protect oocytes and embryos from oxidative stress in the culture medium. melatonin has been shown to be a direct free radical scavenger. objective: effect of melatonin during in vitro oocyte maturation, fertilization and embryo development of mouse oocytes was evaluated. materials and methods: oocytes from supper-ovulated mouse were divided to two groups: cumulus ...

We describe the design of PIRS, a peer-to-peer information retrieval system. Unlike some other proposed approaches, PIRS does not require the centralization of data onto specially designated peers. It is therefore applicable to a larger environment. We explain our design decisions, analyzing its benefits and potential shortcomings. We then show that PIRS significantly improves over search perfo...

there are many approaches in economic literature for investigation of firm performance. in general, those theories very useful for investigation the nature and role of competitive advantage. resource based view, dynamic capability, entrepreneurial theory, neoclassic theory, industrial organization approach are some of those theories. todays, banks try to attract customers through various new me...

Abstract: In todays present world lots of microelectronic statistics is created in apiece and every field. The data that we obtain contains valuable info to forecast the future. Owing enormous magnitude, physical forecasting gives a intricate chore humans. To overwhelm this problem, model made such way so it can predict future by situation with aid training test datasets. Pullman machine or mod...

With the advent of post-genomic era, new technologies create extraordinary possibilities for diagnostics and personalized therapy, transforming todays' medicine. Rooted in both medical genetics and clinical psychiatry, the paper is designed as an integrated source of information of the current and potential future application of emerging genomic technologies as diagnostic tools in psychiatry, m...

Grid Replica systems are gaining foothold in real end user systems, and are used in an increasing number of large scale projects. As such, many of the properties of these systems are well understood. This paper how to handle some minor shortcomings of todays data replica systems, in respect to consistency management, and to their ability to handle derived data sets. We think that both features ...

The impact of results from Information Theory on todays information technology is illustrated by means of derivations from capacity formula and chain rule. By this, the huge possible increase in power and bandwidth efficiency for transmission of analog source signals via modern digital communication techniques is enlightened. The foundations of modern approaches like OFDM, CDMA, coded modulatio...

Todays computational grids are used mostly for batch processing and throughput computing, where jobs are submitted to a queue, processed, and finally delivered for post-mortem analysis. The glogin tool provides a novel approach for grid applications, where interactive connections are required. With the solution implemented in glogin, users are able to utilize the grid for interactive applicatio...

There is an acute problem concerning lymphoma treatment in Ukraine. Previously, due to unavailability of up-to-date chemotherapy (CT) regimes, only 20% of lymphoma patients had a chance for persistent remission after the treatment, 4060% of patients had response to treatment and only 35% of patients had 5-year survival rates. Todays clinical protocols of therapy in lymphoma patients take into a...
