A recent study published by Bianco et all has suggested that pentoxyifylline [3,7-dimethyl-1-(5-oxo-hexyl)-xanthine] reduces morbidity and mortality in patients undergoing bone marrow transplantation (BMT). When compared with a “good risk” control group, pentoxifylline recipients experienced less mucositis (3.7 v 18.7 days,P = .004), less hepaticvenocclusive disease (10% v 65%,P = .001), a lowe...

Disseminated infection with the dimorphic pathogenic fungus Penicillium marneffei is increasingly seen among patients with AIDS in southeast Asian countries. Previous studies have demonstrated the presence of humoral immune responses to this fungus in patient sera; we have confirmed this work using sera from P. marneffei-infected patients (n = 21) to develop Western blots of P. marneffei cytopl...

a total of 183 coagulase negative staphylococcal infected quarters and 64 uninfected quarters were randomly allotted to 4 experimental groups: infected quarters that did not receive any treatment (positive control group; n = 60); infected quarters that received tylosin (n = 61) or cefquinome (n = 62) and also uninfected quarters that did not receive any treatment were considered as negative con...

UV radiation is a potent DNA-damaging agent and a known inducer of skin cancer in experimental animals. To elucidate the role of oncogenes in UV carcinogenesis, we analyzed UV-induced murine skin tumors for mutations in codon 12, 13, or 61 of Ha-ras, Ki-ras, and N-ras oncogenes by amplification of genomic tumor DNAs by the polymerase chain reaction followed by dot-blot hybridization to syntheti...

spherical polyhedron S = (V, F ;E): For a 2-connected planar graph GS = (V,ES), embedded on a sphere (or in the plane), we record the vertices as V and the regions as faces F , and rewrite the directed edges E as ordered 4-tuples e = 〈h, i; j, k〉, where the edge from vertex h to vertex i has face j on the right and face k on the left. (The reversed edge −e = 〈i, h; k, j〉 runs from i to h, with ...

We consider the maximum integral tWo-Commodity flow problem in augmented planar graphs (i.e., with both source-sink edges added) and provide an o(IVI 2 1ogIVI) algorithm for that problem. Let G = (V, E) be a graph and w : E-t Z+ a weight function. Let T C V be an even subset of the vertices of G. A T-cut is an edge-cutset of the graph which divides T into two odd sets. Lomonosov gave a good cha...

BACKGROUND The aim of this study was to investigate differential changes in plasma levels of stromal-cell-derived factor-1 (SDF-1) before and after antibiotic treatment in patients with community-acquired pneumonia (CAP) and observe the association between the severity of CAP and the plasma SDF-1 level. METHODS We gathered blood specimens from 61 adult CAP patients before and after antibiotic...

Given a continuous map f : Sn−1 → Rm and n − m + 1 points p1, . . . , pn−m+1 ∈ Sn−1, does there exist a rotation % ∈ SO(n) such that f(%(p1)) = . . . = f(%(pn−m+1))? We give a negative answer to this question for m = 1 if n ∈ {61, 63, 65} or n ≥ 67 and for m = 2 if n ≥ 5.
