STUDY DESIGN Prospective multicenter cohort study. OBJECTIVE To evaluate the effect of pre- and postoperatively assessed fear avoidance beliefs (FAB) on pain and disability in patients with degenerative lumbar spinal stenosis (LSS) after decompression surgery. SUMMARY OF BACKGROUND DATA To the present, the influence of pre- and postoperative FAB on the prognosis after surgery for LLS is sti...

A factor present in normal rabbit sera enhanced the neutralization of the infectious complex of poliovirus with the pepsin Fab' fragment of rabbit immunoglobulin G (IgG) antibody but showed no activity for the infectious complex of the same virus with IgG antibody. The factor was associated with IgG, and its activity was inhibited by the pepsin Fab' fragment of normal rabbit IgG. The data sugge...

Fast atom bombardment (FAB) mass and MS/MS spectra of a novel quinone antibiotic are presented. Their interpretation is based upon the examination of reductive behavior of model quinones in FAB solvents.

in this paper we show that if q is a power of a prime p , then the projective special linear group psl(2, q) and the stabilizer of a point of the projective line have maximum sum element orders among all proper subgroups of projective general linear group pgl(2, q) for q odd and even respectively

let $mathfrak{f}$ be a formation and $g$ a finite group. a subgroup $h$ of $g$ is said to be weakly $mathfrak{f}_{s}$-quasinormal in $g$ if $g$ has an $s$-quasinormal subgroup $t$ such that $ht$ is $s$-quasinormal in $g$ and $(hcap t)h_{g}/h_{g}leq z_{mathfrak{f}}(g/h_{g})$, where $z_{mathfrak{f}}(g/h_{g})$ denotes the $mathfrak{f}$-hypercenter of $g/h_{g}$. in this paper, we study the structur...

The mechanisms by which antivenom neutralizes the venom are still poorly understood. In the present work, we studied the effects of antivenom, constituted with either F(ab9)2 or Fab, on the processes of absorption and elimination of Vipera aspis venom in experimentally envenomed rabbits. We first concluded from this study that during the few hours after intramuscular injection, the venom rapidl...
