Recent findings with respect to epiblasts before and after implantation have produced proposals for classifying pluripotency into two distinct phases: "naive" and "primed". [25] The baseline stem cells commonly used in science that are referred as Embryonic stem cells (ESCs) are derived from a pre-implantation epiblast; such epiblast is able to generate the entire fetus, and one epiblast cell is able to contribute to all cell lineages if injected into another blastocyst. On the other hand, several marked differences can be observed between the pre- and post-implantation epiblasts, such as their difference in morphology, in which the epiblast after implantation changes its morphology into a cup-like shape called the "egg cylinder" as well as chromosomal alteration in which one of the X-chromosomes undergoes random inactivation in the early stage of the egg cylinder, known as X-inactivation . [26] During this development, the egg cylinder epiblast cells are systematically targeted by Fibroblast growth factors , Wnt signaling, and other inductive factors via the surrounding yolk sac and the trophoblast tissue, [27] such that they become instructively specific according to the spatial organization. [28] Another major difference that was observed, with respect to cell potency, is that post-implantation epiblast stem cells are unable to contribute to blastocyst chimeras , [29] which distinguishes them from other known pluripotent stem cells. Cell lines derived from such post-implantation epiblasts are referred to as epiblast-derived stem cells which were first derived in laboratory in 2007; it should be noted, despite their nomenclature, that both ESCs and EpiSCs are derived from epiblasts, just at difference phases of development, and that pluripotency is still intact in the post-implantation epiblast, as demonstrated by the conserved expression of Nanog , Fut4 , and Oct-4 in EpiSCs, [30] until somitogenesis and can be reversed midway through induced expression of Oct-4 .

An improved ELISA test for determination of potency of Inactivated Poliovirus Vaccine (IPV) is proposed. The method is based on the use of IgG purified from immune rabbit serum conjugated with biotin. Optimized and validated materials for the test can be stored for a long time in the form of ready-to-use kits. Optimization included selection of anti-poliovirus rabbit antibody batches with the best specificity to D-antigen as well as finding the most efficient parameters for all steps of ELISA protocol. The assay is based on direct ("sandwich") ELISA scheme, in which antigens are captured on ELISA plates coated with purified rabbit polyclonal D-antigen specific IgG raised against wild polioviruses of three serotypes. D-antigen specificity of the IgG was at least 10 times higher than to H-antigen (heat-inactivated virus). The presence of antigen was detected using biotin-conjugated IgG from the same source. Eight-point dose-response curves were obtained for each sample and the reference vaccine. The protocol ensured low background (less than OD), linear response over the entire range of optical density measurements (up to OD), and high precision of data (assay variability was about 3%). The quantitative results and the validity of the test were determined by two numerical approaches, linear regression and a new analysis procedure called the local interpolation method. For the first approach we also proposed a new method for testing of parallelism of regression lines. The ELISA protocol for all three types of poliovirus is based on standard off-the-shelf reagents, and is highly reproducible and reliable. An in-house Reference Reagent was formulated and calibrated against the International Reference for IPV.

While this may very well be true, there isn't much evidence that it's actually the lack of pollination which caused the dramatic increase of potency experienced by cannabis enthusiasts at the time. Right around the time growers started producing non-seedy buds, the cannabis breeding scene was also starting to get established. Publications to assist cannabis growers like the High Times magazine appeared on the scene to help growers learn better growing techniques, and cannabis breeders like Nirvana started shipping cannabis seeds of famous strains to growers all around the world by mail order. 

Zoon's vulvitis is a rare, chronic condition of the vulva that presents with burning, pruritus, and dysuria with characteristic lesions and histopathology. Several treatment options have been reported with limited success. A 63-year-old woman with Zoon's vulvitis diagnosed on histopathology was treated with clobetasol propionate %. Complete resolution of her symptoms and lesions occurred in less than 1 week. No recurrence of her symptoms has occurred after 9 months. Zoon's vulvitis may be successfully and expeditiously treated with high potency topical steroids.
