Background: The cryopreservation of human oocyte would make significant contribution to fertility treatments. It could also provide on alternative to embryo preservation for avoidance ethical problems. Embryo cryopreservation is now a successful procedure, but oocyte cryopreservation has poorer results. Materials and Methods: For retrieval of oocyte NMRI mouse were used. after administration of...

Algae are an attractive energy source, but important questions still exist about the sustainability of this technology on a large scale. Two particularly important questions concern the method of cultivation and the type of algae to be used. This present study combines elements of life cycle analysis (LCA) and life cycle costing (LCC) to evaluate open pond (OP) systems and horizontal tubular ph...

BACKGROUND Breast-conserving surgery (BCS) may sometimes lead to deformities in the remaining breast. Oncoplastic surgery (OPS) aims to improve our aesthetic results even in the case of major volume resections. The purpose of this study is to provide an objective evaluation of our initial experience with OPS, mainly based on the levels of satisfaction reported by both patients and surgeons. P...

Using focal stimuli, we successfully recorded oscillatory potentials (OPs) in electroretinograms of the macular regions of 72 normal volunteers. The OPs consisted of three to four wavelets with a mean peak interval of approximately 6.5 msec, consistent with that recorded with conventional full-field stimuli over the entire retina. The changes of amplitude in response to the spot sizes and ring ...

PURPOSE To determine the effect of experimental glaucoma in macaque monkeys on oscillatory potentials (OPs) in the slow-sequence multifocal electroretinogram (mfERG). METHODS Photopic slow-sequence mfERGs were recorded from anesthetized adult macaque monkeys and normal human subjects. The stimulus consisted of 103 equal-sized hexagons within 17 degrees of the fovea. The m-sequence was slowed,...

Optical Packet Switching (OPS) and Optical Burst Switching (OBS) are optical networking concepts based on fully exploiting fast dynamic allocation of (D)WDM channels. Compared to more static approaches focusing on providing endto-end optical channels, OPS and OBS aim at providing greater bandwidth efficiency, granularity and flexibility. In this paper we give an overview of the issues arising w...

Small-scale fisheries (SSFs) in developing countries are expected to play a significant role in poverty alleviation and enhancing food security in the decades to come. To realize this expectation, a better understanding of their informal self-governance arrangements is critical for developing policies that can improve fishers' livelihoods and lead to sustainable ecosystem stewardship. The goal ...

In California, regulatory agencies are concerned about organophosphate (OP) contamination of surface water. OPs originate in part from applications on dormant almond and stone fruit orchards that are washed off during winter rainstorms. Programs conducted by the University of California Statewide Integrated Pest Management Project, University of California Cooperative Extension, and the Biologi...

Do leaks of hydraulic fluids and jet engine lubricating oils cause potentially toxic fumes to be released into the cabins of commercial airliners? If so, do those fumes cause acute and chronic health problems such as headache, nausea, fatigue, memory loss, and neuromuscular damage in airline crew members and passengers? Those simple questions are at the heart of a brewing controversy. Advocacy ...
