STUDY QUESTION: What is the performance of previously established regression models in predicting low and high ovarian response to 150 μg corifollitropin alfa/GnRH-antagonist ovarian stimulation in an independent dataset? SUMMARY ANSWER: The outcome of ovarian stimulation with 150 μg corifollitropin alfa in a fixed, multiple dose GnRH-antagonist protocol can be validly predicted using logistic regression models with AMH being of paramount importance. WHAT IS KNOWN ALREADY: Predictors of ovarian response have been identified in FSH/GnRH agonist protocols as well as ovarian stimulation with corifollitropin alfa/GnRH-antagonist...

Egg yolk is a good external cryoprotectant of mammalian sperm and some wild bird's sperm, but, at least in domestic breeds of chicken (Gallus gallus domesticus), it may inhibit eventual fertilization of ova when high concentrations are used. We hypothesized that egg yolk can protect the sperm from cryo-induced damages providing adequate fertilization in one phylogenetic wild ancestor of current chicken breeds: the Indian red jungle fowl (Gallus gallus murghi). To test the hypothesis, the present study was designed to evaluate different concentrations of egg yolk in extender in comparison with glycerol...

Early histological progression that associates with Delayed Graft Function (DGF) and its relationship to graft outcomes is less well understood. We systematically evaluated early acute and chronic histological changes associated with DGF through serial biopsies (protocol: 3 and 12mos; for-cause) and related them to graft outcomes. 56/294 (19.04%) of our patients had DGF. DGF was associated with a progressive increase in both Banff 't' and 'i' scores from 2 weeks to 3 and 12 months with a resultant increase in T cell mediated Rejection (TCMR) that was significantly greater than those with primary graft function (PGF)...

Background and aims Conditioned Pain Modulation (CPM) is a well-established phenomenon and several protocols have shown acceptable between-subject reliability [based on intraclass correlation coefficient (ICC) values] in pain-free controls. Recently, it was recommended that future CPM test-retest reliability studies should explicitly report CPM reliability based on CPM responders and non-responders (within-subject reliability) based on measurement error of the test stimulus. Identification of reliable CPM paradigms based on responders and non-responders may be a step towards using CPM as a mechanistic marker in diagnosis and individualized pain management regimes...

New York City drinking water quality depends on retention of forest cover in its Catskill Mountains watersheds, yet multiple published analyses of temporally approximate satellite imagery derived no definitive nor agreed upon quantification of either forest cover in the watershed, or, more importantly, its rate of change over time. The objective of this work was to reduce uncertainty surrounding these estimates. We developed a five-pronged protocol that included (1) creation of a 1975-2002 time-series of land use/land cover (LULC) using Cross-Correlation Analysis (CCA); (2) a corrective post classification logic-based algorithm to correct for illogical transitions; (3) a probability-based stratified random sample accuracy assessment; (4) joint probability calculations of the "true" 2002 class proportions; and (5) verification of quantities of our LULC classification, and those of other researchers, versus the statistically derived true proportions...

Daisuke Ino, Masamitsu Iino
To study the signaling mechanism of the development and maintenance of myelinating Schwann cells (SCs) in the peripheral nervous system, in vivo techniques for SC-selective gene manipulation are useful. The present protocol describes an in vivo electroporation method that allows efficient transfection of myelinating SCs in rodent sciatic nerves. This technique allows us to introduce the genes of interest into myelinating SCs by simply applying electric pulses to the sciatic nerve after plasmid DNA injection...

Myelinated fibers are essential for the rapid and efficient propagation of nerve information throughout the body. These fibers result from an intimate crosstalk between myelinating glia and the myelinated axons and, because it is difficult to fully reproduce these interactions in vitro, the basic molecular mechanisms that regulate myelination, demyelination, and remyelination remain unclear. Schwann cells produce myelin in the peripheral nervous system (PNS) and remain associated with the axons of peripheral neurons throughout axonal migration to the target...

Autophagy is a key cellular mechanism involved in the degradation of long-lived proteins and organelles. We and others have previously shown that Schwann cells are able to degrade their own myelin by a form of selective autophagy, or myelinophagy. There is now increasing evidence that myelinophagy could also be aberrantly activated in other demyelinating diseases, including hereditary or inflammatory neuropathies, implicating this pathway in the pathogenesis of these disorders. In this chapter, we describe our protocol to monitor autophagy in peripheral nerves, using the autophagy flux assay...

Myelination cell culture systems are useful tools for studying myelin biology and myelin-related disorders. Compared to a number of established protocols for dissociated pure oligodendrocyte (OL) culture, methods for myelination culture are limited. We recently developed a mixed neuron-glia coculture system that generates robust and efficient myelination. By optimizing cell culture conditions, dissociated neural progenitor cells from embryonic rat spinal cords develop into neurons and glial cells including profiles of oligodendrocyte (OL) lineage...
