El cubrimiento espacial del relevamiento mejora en un factor 16 al realizado por Bajaja et al Targeting the zona pellucida for immunocontraception: This minireview summarizes the main data relevant to the development of contraceptive vaccines based on zona pellucida ZP antigens, as well as the pros and the cons of this immunocontraceptive strategy. Even though the antifertility efficacy of anti-ZP antibodies in humans is not corroborated by a clear relationship Descubridor del neutron yahoo dating spontaneous autoimmunization against the ZP and infertility, passive and active immunization studies in laboratory animals have provided convincing results.

The contraceptive action of anti-ZP antibodies, targeting events situated upstream of gamete fusion, is devoid of potential ethical concerns related to the destruction of early embryos.

The high protein content of the mammalian ZP, knowledge of the complete amino acid sequence of the major ZP proteins, and the high degree of sequence homology between individual species all favour the rapid advancement of anti-ZP vaccine projects. The search for the optimal combination of B cell and T cell epitopes in the vaccine construct will hopefully overcome this problem. Alta Gas ; Notice of Application. Alta Gas, 4th Avenue SW.

Notes about Alta Vista in Chalchihuites, Zacatecas. The Tropic of Cancer marks the northernmost position of the sun Descubridor del neutron yahoo dating its midday zenith, which takes place in the Summer solstice. It so happens that Alta Vista in Zacatecas, corresponds to the westernmost peak where this phenomenon can occur, although the date of the zenith's course differs depending on the latitude of each position and so various archaeoastronomical specialists stress how the ancient indigenous cultures, at least those dating from Mexico's Classical period, valued this finding in developing their calendars.

Finite Element Analysis of Patella Alta: A Patellofemoral Instability Model. This study aims to provide biomechanical data on Descubridor del neutron yahoo dating effect of patella height in the setting of medial patellofemoral ligament MPFL Descubridor del neutron yahoo dating using finite element analysis. The study will also examine patellofemoral joint biomechanics using variable femoral insertion "Descubridor del neutron yahoo dating" for MPFL reconstruction.

A previously validated finite element knee model was modified to study patella alta and baja by translating the patella a given distance to achieve each patella height ratio. Additionally, the models were modified to study various femoral insertion sites of the MPFL anatomic, anterior, proximal, and distal for each patella height Descubridor del neutron yahoo dating, resulting in 32 unique scenarios available for investigation.

In the setting of patella altathe patellofemoral contact Descubridor del neutron yahoo dating decreased, resulting in a subsequent increase in maximum patellofemoral contact pressures as compared to the scenarios with normal patellar height. Additionally, patella alta resulted in decreased lateral restraining forces in the native knee scenario as well as following MPFL reconstruction. Changing femoral insertion sites had a variable effect on patellofemoral Descubridor del neutron yahoo dating pressures; however, distal and anterior femoral tunnel malpositioning in the setting of patella alta resulted in grossly elevated maximum patellofemoral contact pressures as compared to other scenarios.

Patella alta after MPFL reconstruction results in decreased lateral restraining forces and patellofemoral contact area and increased maximum patellofemoral contact pressures. When the femoral MPFL tunnel is malpositioned anteriorly or distally on the femur, the maximum patellofemoral contact pressures increase with severity of patella alta. When evaluating patients with patellofemoral instability, it is important to recognize patella alta as a potential aggravating factor.

Failure to address patella alta in the setting of MPFL femoral tunnel malposition may result in even further increases in patellofemoral contact pressures, making it.

Failure to address patella alta in the setting of MPFL femoral tunnel malposition may result in.

Mechanics of sperm-egg interaction at the zona pellucida. Mammalian sperm traverse several layers of egg vestments before fertilization can occur. The innermost vestment, the zona pellucida, is a glycoprotein shell, which captures and tethers the sperm before they penetrate it.

We report here direct measurements of the force required to tether a motile human sperm as well as independent calculations of this force using flagellar beat parameters observed for sperm of several species on their homologous zonae.

We have compared these sperm-generated forces with the calculated tensile Descubridor del neutron yahoo dating of sperm- zona Descubridor del neutron yahoo dating, and found that a motile sperm can be tethered, at least temporarily, by a single bond. Therefore, sperm can be captured by the first bond formed and tethered permanently by a few. The sperm cannot subsequently penetrate the zona unless the bonds are first eliminated.

However, premature elimination would simply Descubridor del neutron yahoo dating the sperm to escape. Therefore, not only must the bonds be eliminated, but the timing of this must be regulated so that the sperm is already oriented toward the egg and beginning to penetrate as the bonds are broken.

Scintigraphy of normal mouse ovaries with monoclonal antibodies to ZP-2, the major zona pellucida protein. The zona pellucida is an extracellular glycocalyx, made of three sulfated glycoproteins, that surrounds mammalian Descubridor del neutron yahoo dating. Parenterally administered monoclonal antibodies specific for ZP-2, the most abundant zona protein, localize in the zona pellucida.

When labeled with iodine, these monoclonal antibodies demonstrate a remarkably high target-to-nontarget tissue ratio and provide clear external radioimaging of ovarian tissue. We present high-spatial and high-spectral resolution studies of SiO masers in the circumstellar envelopes of late-type stars. These masers occur in the inner layers of the CSEs, in a region dominated by the stellar pulsation, thus being good if not the only probes available to understand the physics in these regions.

The spatial distributions retrieved, some of them for Descubridor del neutron yahoo dating first time, are in clear contradiction with the predictions of the models developed to date. We suggest that spectral line overlap may explain the results obtained.

Transfer of bovine demi-embryos with and without the zona pellucida.

Main · Videos; Harrowing latino...

Bisected bovine embryos with or without the zona Descubridor del neutron yahoo dating were transferred to recipients nonsurgically in five field trials.

Embryos were collected from superovulated donors 6. Pregnancies were diagnosed at 44 to 68 d "Descubridor del neutron yahoo dating" gestation. Except for trial 2, half of the demi-embryos were twinned, one to each uterine horn; twinning did not significantly affect the proportion developing to fetuses for any of the demi-embryo groups.

It is concluded that placing post-compaction demi-embryos into the zona pellucida for transfer does not improve pregnancy rates significantly. Viscous forces are predominant in the zona pellucida mechanical resistance. The zona pellucida ZP is a multilayer glycoprotein spherical shell surrounding mammalian eggs. The ZP's mechanical response plays a crucial role in mammalian fertilization and is a parameter commonly adopted in "in vitro fertilization" to characterize Descubridor del neutron yahoo dating oocytes quality.

While it is assumed that ZP mechanical response is purely elastic, here we prove that dissipative forces cannot be neglected. Physiologically, this evidence implies that an increase in the spermatozoa motility can induce dramatic changes on the ZP reaction force turning ZP shell in an impenetrable barrier leading to fertility impairments.

Densidad de desarrollo alta y baja en Puerto Rico. Crouch gait deformity is common in Descubridor del neutron yahoo dating with cerebral palsy and often is associated with patella alta.

Patellar tendon advancement typically is used to correct patella alta and restore normal knee mechanics. The purpose of this study was to determine the mechanical strength of surgical constructs used for fixation Descubridor del neutron yahoo dating patellar advancement procedures.

This study used a cadaveric model to determine which of 3 surgical techniques is biomechanically optimal for patellar tendon advancement in treating patella alta. Twenty-four human cadaveric knees 8 per group were prepared using 1 of 3 different common surgical techniques: The patella was loaded from 25 to N at 1 Hz for cycles.

A significant difference in patella displacement under cyclical loading was found between surgical techniques. Tibial tubercle osteotomy exhibited significantly less displacement under cyclical loading than distal patella excision and repair P Characterization of oocyte retrieval cycles with empty zona pellucida. To identify the factors that characterize cycles with empty zona pellucida EZP. Thirty-six oocyte retrieval cycles from which EZP were collected and another 36 cycles from which no EZP was collected were compared.

The patients were divided into three groups: The fertilization rate of the collected oocytes and the rate of good embryo formation were significantly lower in the cycles with EZP. No significant difference was observed between the three groups in terms of age, number of oocytes collected, or hormone levels before and after the oocyte retrieval. The fertilization and pregnancy rates were highest in the patients with no EZP being collected during any cycle, followed by those experiencing cycles both with and without EZP, and then by those with EZP collected during all cycles.
