Teyyar eschatology, as a doctrine of the ultimate destiny of mankind, is deeply rooted in the concept of the ultimate goal, which is regarded as a true result, though it emerges as a tool designed to fill some of the emptiness created by humanity in the course of natural science practice. Teillard felt that the deplorable state of modern mankind was the result of his neglect of eschatology, his inability to adapt to the needs of his activities, and his lack (...) of courage in further design. "A lighter skyscraper of hope is being constructed," G. Grespi notes. The belief that the Earth is exhausting its limited resources necessarily leads to the thought of the destruction of the Earth.

While outcomes for children with T-cell acute lymphoblastic leukemia have improved dramatically, survival rates for patients with relapsed/refractory disease remain dismal. Prior studies indicate that glucocorticoid resistance is more common than resistance to other chemotherapies at relapse. In addition, failure to clear peripheral blasts during a prednisone prophase correlates with an elevated risk of relapse in newly diagnosed patients. Here we show that intrinsic GC resistance is present at diagnosis in early thymic precursor T-ALLs as well as in a subset (...) of non-ETP T-ALLs. GC-resistant non-ETP T-ALLs are characterized by strong induction of JAK/STAT signaling in response to interleukin-7 stimulation. Removing IL7 or inhibiting JAK/STAT signaling sensitizes these T-ALLs, and a subset of ETP T-ALLs, to GCs. The combination of the GC dexamethasone and the JAK1/2 inhibitor ruxolitinib altered the balance between pro- and anti-apoptotic factors in samples with IL7-dependent GC resistance, but not in samples with IL7-independent GC resistance. Together, these data suggest that the addition of ruxolitinib or other inhibitors of IL7 receptor/JAK/STAT signaling may enhance the efficacy of GCs in a biologically defined subset of T-ALL.Leukemia advance online publication, 30 May 2017; doi:10.1038/leu.2017.136.

The article looks into the issues, outlined in M. Baker's The Atoms of Language: The Mind's Hidden Rules of Grammar. This work is notable for the parametric theory of the languages, set out in it, according to which languages are different, nevertheless retaining the ability to be compared. That can be further supported by the assertion that the differences among languages are determined by "a smallish number of discreet elements, called parameters."What is more, the diversity of language reveals a certain (...) regularity, very much resembling that of Mendeleev's periodic table of chemical elements. Our research team of professional linguists and philosophers put this claim to a critical analysis, the results of which are featured in this article. One of the major ones among them is the supposition that Baker, in accordance with the traditions of Chomsky generative linguistics, turns temporal continuums into special relations. He did that without discussing the consequences of such move, which made it impossible to develop the psychological and linguistic aspect of the subject raised by him. (shrink)

Canada has a marked shortfall between the supply and demand for kidneys for transplantation. Median wait times for deceased donor kidney transplantation vary from 5.8 years in British Columbia, 5.2 years in Manitoba and 4.5 years in Ontario to a little over 2 years in Quebec and Nova Scotia. Living donation provides a viable option for some, but not all people. Consequently, a small number of people travel abroad to undergo kidney transplantation by commercial means. The extent to which they (...) are aware of the potential risks to their health and the health of the kidney vendors is unclear. Travel abroad to obtain a kidney commercially i.e. transplant tourism (TT), raises ethical issues which include the exploitation of the poor, uncertainty of donor informed consent to nephrectomy, poor clinical care and lack of follow up for the donor, commodification of the body and inequity of access to medical care for donors. Also, TT widens socioeconomic disparities in access to transplantation, differing from the Canadian system of universal coverage for healthcare. The Canadian transplant community has discussed how to respond to patients who plan to travel abroad for TT or return with a purchased kidney. Unease rests in the tension between the duty to care for legitimate Canadian residents and the unwillingness to enable TT. This paper discusses three anonymized cases and the Canadian responses to TT as recorded in academic literature and a formal statement by relevant professional bodies. (shrink)

The objectives of this study were to develop a high-density chromosome bin map of homoeologous group 7 in hexaploid wheat, to identify gene distribution in these chromosomes, and to perform comparative studies of wheat with rice and barley. We mapped 2148 loci from 919 EST clones onto group 7 chromosomes of wheat. In the majority of cases the numbers of loci were significantly lower in the centromeric regions and tended to increase in the distal regions. The level of duplicated loci (...) in this group was 24% with most of these loci being localized toward the distal regions. One hundred nineteen EST probes that hybridized to three fragments and mapped to the three group 7 chromosomes were designated landmark probes and were used to construct a consensus homoeologous group 7 map. An additional 49 probes that mapped to 7AS, 7DS, and the ancestral translocated segment involving 7BS also were designated landmarks. Landmark probe orders and comparative maps of wheat, rice, and barley were produced on the basis of corresponding rice BAC/PAC and genetic markers that mapped on chromosomes 6 and 8 of rice. Identification of landmark ESTs and development of consensus maps may provide a framework of conserved coding regions predating the evolution of wheat genomes. (shrink)

This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex func- tioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the Intradimensional/ (...) Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.

This study investigates the ability of individuals with psychopathy to perform passive avoidance learning and whether this ability is modulated by level of reinforcement/punishment. Nineteen psychopathic and 21 comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), were given a passive avoidance task with a graded reinforcement schedule. Response to each rewarding number gained a point reward specific to that number (i.e., 1, 700, 1400 or 2000 points). Response to each punishing number lost a point punishment specific (...) to that number (i.e., the loss of 1, 700, 1400 or 2000 points). In line with predictions, individuals with psychopathy made more passive avoidance errors than the comparison individuals. In addition, while the performance of both groups was modulated by level of reward, only the performance of the comparison population was modulated by level of punishment. The results are interpreted with reference to a computational account of the emotional learning impairment in individuals with psychopathy. (shrink)
