Animals, including humans, engage in many forms of foraging behavior in which resources are collected from the world. This paper examines human foraging in a visual search context. A real-world analog would be berry picking. The selection of individual berries is not the most interesting problem in such a task. Of more interest is when does a forager leave one patch or berry bush for the next o...
The title compound, C(10)H(11)Cl(2)N(3)S, was prepared by the reaction of 4-ethyl-thio-semicarbazide and 2,4-dichloro-benzaldehyde. It is approximately planar, the dihedral angle between the benzene ring and the thio-urea unit being 8.43 (18)°. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds generate R(2) (2)(8) loops.
The technic for isolation-perfusion of the rat hind limb is described. By the stand ardized technic, limb viability was well maintained, and leakage of anticancer agents into the systemic circulation was negligible. The gross and microscopic response of the Walker 256 carcinosarcoma to perfusion with triethylenethiophosphoramide is de scribed. The preparation permits study of the many variables...
In the title compound, C15H22N2S2, the di-thio-carbazate group adopts an E conformation with respect to the C=N bond of the benzyl-idene moiety. In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers with an R (2) 2(8) ring motif. The dimers are linked via C-H⋯π inter-actions, forming chains propagating along [100].
BACKGROUND Relapsing primary central nervous system lymphoma carries a poor prognosis when treated with conventional chemotherapy with a one-year overall survival of 25-40%. Encouraging results have been shown with intensive chemotherapy followed by autologous hematopoietic stem cell rescue. We report the results of a large multicenter retrospective analysis of intensive chemotherapy followed b...
The prognosis of patients with central nervous system relapse of aggressive lymphoma is very poor with no therapy established so far. In a prospective multicenter phase II study, we evaluated a potentially curative chemotherapy-only regimen in these patients. Adult immunocompetent patients 65 years of age or under received induction chemotherapy with MTX/IFO/DEP (methotrexate 4 g/m(2) intraveno...
