background: the rapidity of progression of amyotrophic lateral sclerosis (als) to death or respiratory failure impacts patients, clinicians, and clinical investigators. the aim of this study is to evaluate of the pulmonary function tests (pfts) in patients with als and the association between these pfts and survival methods: a total of 36 als patients who pfts, including vital capacity (vc), ma...

Three perennial ryegrass (Lolium perenne) populations (R1, R2, and R3) with suspected resistance (R) to acetolactate synthase (ALS) or acetyl-CoA carboxylase (ACCase) herbicides were collected from wheat (Triticum aestivum) fields in northwestern Greece study the underlying mechanisms of their impact on growth rate competitive ability against wheat. Preemergence postemergence plant dose–respons...

Amyotrophic lateral sclerosis (ALS) is a fatal degenerative motor neuron disease. Approximately 20 percent of familial ALS cases are caused by mutations in the Cu/Zn superoxide dismutase (SOD1) gene. Rodents expressing mutant SOD1 transgenes develop progressive, fatal motor neuron disease and disease onset and progression is dependent on the level of SOD1. We investigated the possibility that a...

BACKGROUND While multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS) are primarily inflammatory and degenerative disorders respectively, there is increasing evidence for shared cellular mechanisms that may affect disease progression, particularly glial responses. Cyclooxygenase 2 (COX-2) inhibition prolongs survival and cannabinoids ameliorate progression of clinical disease in anim...

Despite an improved understanding of the genetic background and the pathomechanisms of amyotrophic lateral sclerosis (ALS) no novel disease-modifying therapies have been successfully implemented in clinical routine. Riluzole still remains the only clinically approved substance in human ALS treatment with limited efficacy. We have previously identified pharmacological rho kinase (ROCK) inhibitor...

Autophagy is dysfunctional in many degenerative diseases including myopathies. Mutations in valosin-containing protein (VCP) cause inclusion body myopathy (IBM) associated with Paget's disease of the bone, fronto-temporal dementia and amyotrophic lateral sclerosis (IBMPFD/ALS). VCP is necessary for protein degradation via the proteasome and lysosome. IBMPFD/ALS mutations in VCP disrupt autophag...

Sulfometuron methyl (SM), a potent new sulfonylurea herbicide, inhibits growth of the yeast Saccharomyces cerevisiae on minimal media. Sixty-six spontaneous mutants resistant to SM were isolated. All of the resistance mutations segregate 2:2 in tetrads; 51 of the mutations are dominant, five are semidominant and ten are recessive. The mutations occur in three linkage groups, designated SMR1, sm...
