introduction: many factors are related to the disability of subjects with chronic low back pain. fear-avoidance of injury and movement are the most important risk factors to increase the disability followed by decreased physical activity in these patients. the aim of current study was to compare the level of disability and fear-avoidance between two groups of low back pain patients with and wit...

Various methods are used to remove nonspecific inhibitors from sera before titering viral hemagglutination-inhibiting antibodies. These methods have several undesirable features; some are tedious and time-consuming, some remove antibody along with nonspecific inhibitors, and different techniques are usually required to remove the nonspecific inhibitors for different viruses. This communication ...

Two classes of thalamic nuclei project to either middle layers or upper layers, including layer 1, of the neocortex, and are referred to as 'specific' and 'nonspecific' nuclei, respectively. The electrophysiological properties of the nonspecific nuclei have not been investigated, largely because of the paucity of in vitro slice preparations containing intact nonspecific pathways. In this study,...

Nonspecific protein-DNA interactions are inherently dynamic and involve both diffusion of the protein along the DNA and hopping of the protein from one DNA molecule or segment to another. Understanding how gene regulatory proteins interact nonspecifically with DNA in terms of both structure and dynamics is challenging because the experimental observables are an ensemble average of many rapidly ...

Evidence • A meta-analysis1 (N = 1804) examined 2 magnetic resonance imaging (MRI) and computed tomography (CT) trials and 4 x-ray trials; 0% to 44% of patients had sciatica. -The trials were of relatively good quality but there was a lot of heterogeneity (except with pain). -Short-term and long-term outcomes of pain, function, quality of life, mental health, and patient satisfaction did not di...
