Amyotrophic lateral sclerosis (ALS) is an adult-onset disease characterized by the selective degeneration of motor neurons in the brain and spinal cord progressively leading to paralysis and death. Current diagnosis of ALS is based on clinical assessment of related symptoms. The clinical manifestations observed in ALS appear relatively late in the disease course after degeneration of a signific...
PURPOSE The Kii Peninsula of Japan, together with Guam and West New Guines, has one of the highest incidences of amyotrophic lateral sclerosis (Kii ALS) in the world. There is a controversy whether the etiology is the same or not between sporadic ALS and Kii ALS. Skin studies from patients with sporadic ALS have shown unique pathological and biochemical abnormalities. However, there has been no...
The clinical approach to patients with amyotrophic lateral sclerosis (ALS) has been largely modified by the identification of novel genes, the detection of gene mutations in apparently sporadic patients, and the discovery of the strict genetic and clinical relation between ALS and frontotemporal dementia (FTD). As a consequence, clinicians are increasingly facing the dilemma on how to handle ge...
We investigated the role of the immune system in the pathogenesis of amyotrophic lateral sclerosis (ALS) by studying the long-term consequences of ALS immunoglobulin (Ig) application on the levator auris muscle of the mouse. We applied Ig from seven ALS patients, four disease controls, and a pool of normal Ig (6 mg of Ig in 2 weeks) by subcutaneous injection; removed the muscles 4 to 12 weeks a...
سابقه و هدف: بیماری مالتیپل اسکلروزیس1 (MS) شایع ترین بیماری خودایمنی سیستم عصبی مرکزی در سنین جوانی می باشد. فاکتورهایی مانند عوامل محیطی و زمینۀ ژنتیکی در ابتلا به بیماری مالتیپل اسکلروزیس دخیل می باشند. از آنجا که miRNAها در سلول های عصبی و گلیال نقش مهمی در سطوح تنظیمی پس از رونویسی دارند، تغییر در عملکرد آنها به واسطه پلی مورفیسم‌ها و در نهایت تغییر بیان آنها در سیستم عصبی می تواند زمی...
During the transition from pregnancy to lactation, dairy cows experience a 70% reduction in plasma IGF-I. This reduction has been attributed to decreased hepatic IGF-I production. IGF-I circulates predominantly in multi-protein complexes consisting of one molecule each of IGF-I, IGF binding protein-3 and the acid labile subunit (ALS). Recent studies in the mouse have shown that absence of ALS r...
Recently, C9orf72 hexanucleotide (GGGGCC) repeat expansion in intron 1 was reported to be the most common cause of sporadic and familial amyotrophic lateral sclerosis (ALS)/frontotemporal dementia (FTD) in the Caucasian population. The frequency of the intronic repeat expansion is up to 21%-57% in familial ALS and 3%-21% in sporadic ALS.In the Japanese population, the C9orf72 repeat expansion w...
Amyotrophic lateral sclerosis (ALS) is recognized as a motor neuron disorder affecting the structure and function of the brain and neuromuscular system. Very little is known, however, that the nervous system degeneration is dependent on disease phenotypes of ALS. The purpose of this study was to determine the degree of brain white matter (WM) structure degeneration in four ALS patient groups ch...
INTRODUCTION A decreased cerebrospinal fluid (CSF) p-Tau181 to total tau ratio (p/t-tau) is a biomarker for frontotemporal lobar degeneration with TDP43 inclusions (FTLD-TDP) and for amyotrophic lateral sclerosis (ALS). CSF light chain neurofilaments (NfL) are increased in ALS. We examined whether CSF p/t-tau and NfL are related to ALS status in FTLD-TDP. METHODS We compared CSF p/t-tau and N...
OBJECTIVES Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, and sepsis is a frequent cause of death in hospitalised patients. We investigated the relationship between ALS and the subsequent risk of sepsis. DESIGN A retrospective cohort analysis. SETTING Patients with ALSs diagnosed between 2000 and 2010 in Taiwan National Health Insurance Research Database. PARTIC...
