We show that the free-by-cyclic groups of the form F2 o Z act properly cocompactly on CAT(0) square complexes. We also show using generalized Baumslag–Solitar groups that all known groups defined by a 2-generator 1-relator presentation are either SQ-universal or are cyclic or isomorphic to a soluble Baumslag–Solitar group.

Composites of heterospin molecular magnet [EuIII(SQ)3bipy] in a polystyrene (PS) matrix have been synthesized. This complex contains four paramagnetic centers - the Eu3+ ion and three SQ ligands (SQ—3,6-di-tert-butyl benzoquinone radical anion); bipy (bipyridyl) is diamagnetic. It has established that intensive mechanical activation [EuIII(SQ)3bipy]/PS samples leads to an reological explosion, ...

L-Asparaginase, in the dose of greater than or equal to 6000 IU/sq m three times weekly, was demonstrated to be an effective agent in reinduction of remissions in childhood leukemia. Four hundred thirteen children with acute lymphocytic leukemia were treated with L-asparaginase. Doses i.m. ranged from 300 to 12,000 IU/sq m. None of the patients had received prior asparaginase therapy. 6-Mercapt...

Introduction: This study evaluated algorithm-based qualitative (ABQ) method for vertebral fracture (VF) evaluation with reference to semi-quantitative (SQ) method and bone mineral density (BMD) measurement. Methods: Mr. OS (Hong Kong) and Ms. OS (Hong Kong) represent the first large-scale cohort studies on bone health in elderly Chinese men and women. The current study compared Genant’s SQ meth...

BACKGROUND Sleep disorders are prevalent complication in patients with end-stage renal disease undergoing hemodialysis (HD). The factors affecting sleep quality (SQ) of patients on HD have not been completely recognized yet. In addition, some studies have shown that poor SQ increases the risk of mortality in patients on HD. OBJECTIVES This study aimed to identify the prevalence of poor SQ and...

A new cell line designated SQ-A was established from the spleen of a leukemic DBA/2J mouse inoculated with the anemic strain of Friend erythroleukemia virus (FLV-A). The cells are similar in morphology, growth pattern, and tumorigenicity to our prototype erythroleukemia line 5-86 but are more sensitive to the cytotoxic effects of inducers of differentiation. The virus produced by SQ-A cells ind...
