Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease. It is typically fatal within 2-5 years of symptom onset. The incidence of ALS is largely uniform across most parts of the world, but an increasing ALS incidence during the last decades has been suggested. Although recent genetic studies have substantially improved our understanding of the causes of ALS, especially fami...
OBJECTIVE: Review the literature from 2003 to 2006 to determine if new data change the conclusions of a previous review (Neuroepidemiology 2003; 22:217-228) that sports and trauma are probably (“more likely than not”) not risk factors for developing ALS. BACKGROUND: Reported apparent excess occurrence of ALS in professional Italian soccer players has rekindled the discussion, whether sports or ...
Respiratory syncytial virus (RSV) causes severe lower respiratory tract infections, yet no vaccines or effective therapeutics are available. ALS-8176 is a first-in-class nucleoside analog prodrug effective in RSV-infected adult volunteers, and currently under evaluation in hospitalized infants. Here, we report the mechanism of inhibition and selectivity of ALS-8176 and its parent ALS-8112. ALS-...
BACKGROUND Prehospital care is classified into ALS- (advanced life support) and BLS- (basic life support) levels according to the methods used. ALS-level prehospital care uses invasive methods, such as intravenous fluids, medications and intubation. However, the effectiveness of ALS care compared to BLS has been questionable. AIM The aim of this systematic review is to compare the effectivene...
The diagnosis of amyotrophic lateral sclerosis (ALS) is mainly based on clinical and electrophysiological features. It is yet to be confirmed if cystatin C (Cys-C) can be a candidate diagnostic biomarker for ALS. This retrospective study aimed at investigating the changes in the level of Cys-C levels in the cerebrospinal fluid (CSF) of Chinese patients with ALS. CSF and serum samples obtained f...
OBJECTIVES The ratio of the length of the index finger (2D) to the ring finger (4D) (2D:4D) has been reported to be lower (ie, 2D<4D) in people with amyotrophic lateral sclerosis (ALS) than non-ALS controls. This has led to suggestions that exposure to increased prenatal testosterone, which also lowers this ratio, could be a risk factor for ALS. In an attempt to test this hypothesis, we examine...
BACKGROUND Patients with ALS may be exposed to variable degrees of chronic intermittent hypoxia. However, all previous experimental studies on the effects of hypoxia in ALS have only used a sustained hypoxia model and it is possible that chronic intermittent hypoxia exerts effects via a different molecular mechanism from that of sustained hypoxia. No study has yet shown that hypoxia (either chr...
Cerebrospinal Fluids (CSF) of Amyotrophic Lateral Sclerosis (ALS) patients have increased levels of the inflammatory cytokine IL-18. Because IL-18 is produced by dendritic cells stimulated by the Platelet-activating factor (PAF), a major neuroinflammatory mediator, it is expected that PAF is involved in ALS. Pilot experimental data on amplification of PAF receptor (PAFR) mRNA by RT-PCR show tha...
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease. Data from the literature show that systemic immune activation plays a role in ALS. OX40 (CD134) is member of the tumor necrosis factor receptor family and is expressed selectively on activated T lymphocytes. The aim of the study was to measure serum soluble OX40 (sOX40) levels in patients with ALS. The study included 25 ALS pat...
Previous studies suggest that in amyotrophic lateral sclerosis (ALS) the abductor pollicis brevis (APB) and first dorsal interosseous (FDI) are more severely involved than abductor digiti minimi (ADM). To elucidate the pattern, frequency, extent, and specificity of such dissociated muscle atrophy in ALS, compound muscle action potentials recorded from APB, FDI, and ADM were analyzed in 77 ALS p...
