Hydroecology and river restoration : 3 Ripe for research and synthesis
6 [1] Research at the intersection of hydrology and ecology is central to a future in which 7 human and ecological needs for water are met. We briefly identify several compelling 8 research questions at this intersection, then focus on a critical research area central to 9 hydroecology: river and stream restoration. Challenges in this area include the 10 development of science to evaluate the e...
متن کاملI-45: FISH and Array CGH for PGD of Cancer
We developed several FISH approaches to enable preimplantation genetic diagnosis of cancer predisposition syndromes. An overview of the applications and the results of those PGDs will be provided. In addition we developed several novel tools to genome wide screen for CNVs and SNPs in single cells. Those technologies are now being applied for polar body, blastomere and blastocyst screening for c...
متن کاملI-3: Reactive Oxygen Species: A Dilemma for
Spermatozoa are very special cells and constantly exposed to the interphase between oxidative stress through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions of spermatozoa as being the only cells with such high polarization and exerting their functions outside the body, even in a differen...
متن کاملA review on recent techniques for elimination of fish fertilized egg adhesiveness
The eggs of many fresh water fishes become sticky after activation and contact with water. The stickiness property is caused by presence of glycoprotein molecules in outer layer of eggs. In sturgeons the fourth layer of egg (jelly coat) leaks after contacting with water. In teleosts outer zona-radiate is responsible for stickiness. Egg stickiness is important in natural reproduction, whereas eg...
متن کاملMarine fish egg hydration is aquaporin-mediated.
The positive buoyancy of marine fish eggs in sea water, allowed by hydration of the oocyte, is critical for their survival and dispersion in the ocean. We isolated an aquaporin, SaAQP1o, that belongs to a unique subfamily of aquaporin-1-like channels specifically evolved in teleosts and mainly expressed in the ovary. We further show that hormone-induced fish oocyte hydration is a highly control...
