in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
E. Brandstätter, G. Gigerenzer, and R. Hertwig (2006) contended that their priority heuristic, a type of lexicographic semiorder model, is more accurate than cumulative prospect theory (CPT) or transfer of attention exchange (TAX) models in describing risky decisions. However, there are 4 problems with their argument. First, their heuristic is not descriptive of certain data that they did not r...
Until recently, loss aversion has been inferred exclusively from choice asymmetries in the loss and gain domains. This study examines the impact of the prospect of losses on exploratory search in a situation in which exploration is costly. Taking advantage of the largest available data set of decisions from experience, analyses showed that most people explore payoff distributions more under the...
This study presents the expression pattern and functions of thymosin beta 10 (Tbeta10), a Tbeta4 homologue during the development of mouse lower first molars. An in situ signal of Tbeta10 was detected on embryonic day 10.5 (E10.5)-E15.5 mainly in dental mesenchymal cells as well as in dental epithelial cells, while Tbeta4 was expressed in dental epithelial cells. In the late bell stage, preodon...
We recently reported the expression of podoplanin in the apical bud of adult mouse incisal tooth. This study was aimed to investigate the distribution of podoplanin-expressing cells in mouse tooth germs at several developing stages. At the bud stage podoplanin was expressed in oral mucous epithelia and in a tooth bud. At the cap stage podoplanin was expressed on inner and outer enamel epithelia...
I N T R O D U C T I O N Beroid ctenophores possess a system of mesogleal muscle fibers organized into several distinct fields and innervated by processes of the ectodermal nerve net (Hertwig, 1880; Franc, 1970; Hernandez-Nicaise , 1973 a,b,c). Each muscle fiber is a single cell tha t appears to contract in a tonic fashion when stretched and displays no striation pat tern. This together with oth...
Cell proliferation is a key regulator of tissue morphogenesis. We examined cell proliferation and cell division in zebrafish lens epithelium by visualizing cell-cycle phases and nuclear positions, using fluorescent-labeled geminin and histone proteins. Proliferation was low in the anterior region of lens epithelium and higher in the marginal zone anterior to the equator, suggesting that the pro...
In this paper we look at the well known phenomenon of conjunction fallacies (Tversky & Kahneman, 1983) from a linguistic perspective. We are particularly interested in understanding the impact of this phenomenon on our understanding of compositionality, a core assumption of contemporary linguistic theories about language meaning. We will argue that contra Hertwig, Benz, and Krauss (2008), conju...
In 1906 the Nobel Prize in Physiology or Medicine was shared between Camillo Golgi and Ramón y Cajal in recognition of their work on the structure of the nervous system. Golgi's most impressive contribution was his method, described in 1873. This was applied in studies of the cerebellum, the olfactory bulb, hippocampus and the spinal cord. These studies together with his earlier work were inclu...
Does risk taking behavior reflect intrinsic or constructed preferences? This question is deeply rooted in psychology and decision science, but is still the subject of a lively debate. The current paper suggests that the degree of support for the idea of consistent constructs of risk taking might be contingent upon the methodology used in the experiment. Specifically, it addresses the properties...
