Background: Inadequate sleep is correlated with morbidity and mortality among older adults. However, the longitudinal relationship between subjective sleep quality and risk of falls in the elderly remains to be clarified. Methods: Study participants were from Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS) sites (1071 community-dwelling people ≧65 years of age, mean, 71 years). Subjective sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI)...

Mutations often have drastically different effects in different genetic backgrounds; understanding a gene's biological function then requires an understanding of its interaction with genetic diversity. The antioxidant enzyme cytosolic superoxide dismutase, cSOD, catalyzes the dismutation of the superoxide radical, a molecule that can induce oxidative stress if its concentration exceeds cellular control. Accordingly, Drosophila melanogaster lacking functional cSOD exhibit a suite of phenotypes including decreased longevity, hypersensitivity to oxidative stress, impaired locomotion, and reduced NADP(H) enzyme activity in males...

OBJECTIVES: Locomotive syndrome (LS) encompasses conditions that may lead to the need for nursing services. We aimed to quantify the association between exercise habits during youth or the middle-age years and both physical function and the presence of LS in Japanese elderly people. METHODS: We examined 460 participants of the eighth, ninth, and tenth iterations of the Miyagawa study. Participants were divided into an LS group and a no-LS group according to their scores on the 25-question Geriatric Locomotive Function Scale...

OBJECTIVES: Idiopathic normal pressure hydrocephalus (iNPH) is very prevalent in aging, underdiagnosed, and represents a rare cause of reversible neurological condition. The clinical triad of iNPH - gait, cognitive and urinary symptoms - and its neuroradiological features (i.e. ventriculomegaly) are not specific and found a various neurodegenerative and/or vascular conditions. We present our iNPH standardized protocol at the Geneva University Hospitals involving a multispecialty team of behavioral neurologists, neurosurgeons, neuropsychologists, engineers, and physical therapists...

Atypical antipsychotics particularly olanzapine are associated with obesity and serious metabolic disturbances. As green tea (Camellia sinensis) is generally associated with beneficial effects on obesity and other metabolic disturbances, this study was undertaken to evaluate the effect of green tea aqueous extract (GTAE) on olanzapine induced weight gain and metabolic abnormalities in rats. Male Wistar rats were divided into eight groups: control, olanzapine (5mg/kg/day, IP.), GTAE (25, 50 and 100mg/kg/day, IP...

Aberrant histaminergic function has been proposed as a cause of tic disorders. A rare mutation in the enzyme that produces histamine (HA), histidine decarboxylase (HDC), has been identified in patients with Tourette syndrome (TS). Hdc knockout mice exhibit repetitive behavioral pathology and neurochemical characteristics of TS, establishing them as a plausible model of tic pathophysiology. Where, when, and how HA deficiency produces these effects has remained unclear: whether the contribution of HA deficiency to pathogenesis is acute or developmental, and where in the brain the relevant consequences of HA deficiency occur...

Mutations in FAT4 gene, one of the human FAT family genes, have been identified in Van Maldergem syndrome (VMS) and Hennekam lymphangiectasia-lymphedema syndrome (HS). The FAT4 gene encodes a large protein with extracellular cadherin repeats, EGF-like domains and Laminin G-like domains. FAT4 plays a role in tumor suppression and planar cell polarity. Drosophila contains a human FAT4 homologue, fat. Drosophila fat has been mainly studied with Drosophila eye and wing systems. Here, we specially knocked down Drosophila fat in nerve system...

Fragile X syndrome (FXS) is the most common cause of heritable intellectual disability and autism and affects ~1 in 4000 males and 1 in 8000 females. The discovery of effective treatments for FXS has been hampered by the lack of effective animal models and phenotypic readouts for drug screening. FXS ensues from the epigenetic silencing or loss-of-function mutation of the fragile X mental retardation 1 (FMR1) gene, which encodes an RNA binding protein that associates with and represses the translation of target mRNAs...

Irritable bowel syndrome (IBS) is a functional gastrointestinal disease with complex pathophysiology involving the brain-gut axis. To assess the effects of Wasabia koreana (WK) on IBS, we employed a mouse model of colonic zymosan injection presenting with diarrhea-predominant IBS-like symptoms. Oral WK administration significantly diminished stool score, suppressed colon length and weight change, and minimized body weight loss without affecting food intake. In WK-treated mice, the submucosal thickening and epithelial lining of the colon were inhibited and were similar to those of naïve mice...

Bone and joint diseases are severe problems in the elderly;therefore, the development of their treatment or prophylaxis is quite important. Our study shows that the prevalence of osteoporosis and osteoarthritis is very high, and its impact on quality of life is strong. The treatment rate of osteoporosis is less than 10%, and awareness programs for prevention of osteoporosis and osteoarthritis disorders such as locomotive syndrome are needed.

The Japanese Orthopaedic Association has proposed the term "locomotive syndrome" to designate a condition that places a person at high risk for long-term care. However, in daily clinical practice, even when a diagnosis of locomotive syndrome is made, exercise therapy often cannot be successfully performed in some patients owing to their lack of motivation. We speculated that locomotive syndrome and depressive states co-exist in elderly people. The purpose of this study was to determine the presence or absence of depressive states in older patients aged ≥ 65 years who were diagnosed with locomotive syndrome...

The mechanisms underlying social dysfunction in neuropsychiatric conditions like obsessive-compulsive disorder (OCD) and Tourette syndrome (TS) remain uncertain. Dysfunctions in basal ganglia, including reduced number of striatal cholinergic interneurons (SCIN), have been involved in their pathophysiology. To explore the role of SCIN in relation to perseverative behaviors we characterized a new transgenic mouse model in which inducible ablation of SCIN is achieved with high efficiency in a cell-type and region specific manner...

OBJECTIVE: The term Locomotive Syndrome refers to conditions in which the elderly are at high risk of inability to ambulate due to problems in locomotor system. For Locomotive Syndrome screening, the 25-Question Geriatric Locomotive Function Scale was created. The objective here was to translate, adapt culturally to Brazil, and study the psychometric properties of 25-Question Geriatric Locomotive Function Scale. METHOD: The translation and cultural adaptation of 25-Question Geriatric Locomotive Function Scale were carried out, thus resulting in GLFS 25-P, whose psychometric properties were analyzed in a sample of 100 elderly subjects...

Mammalian aging is often characterized by metabolic disturbances, cognitive declines and DNA repairs deficiency, but the underlying molecular mechanisms are still not well understood. Alterations in DNA repair can significantly exacerbate aging. Mammalian neuronal cells which accumulate unrepaired DNA damage over time could potentially lead to brain functions disorders. Focusing on the ATP-dependent RecQ-type DNA helicase, an enzyme involved in repair of double strand DNA, a mouse model of Werner syndrome (WS) had been proposed as a model of accelerated aging...

Research has shown that permethrin, a Type-I pyrethroid, increases triglyceride (fat) accumulation in adipocytes. Little is known, however, about any similar effect of deltamethrin, a Type-II pyrethroid, which produces a distinct syndrome of poisoning in mammals compared with permethrin. This study was therefore aimed to explore the role of deltamethrin on fat accumulation in 3T3-L1 adipocytes and Caenorhabditis elegans. Deltamethrin (10 μM) significantly increased the fat accumulation in 3T3-L1 adipocytes and wild type C...

BACKGROUND: Uner Tan syndrome (UTS) cases with habitual quadrupedal locomotion (QL), impaired intelligence, and dysarthric or no speech predominantly use lateral sequence (LS) gait like nonprimates rather than the predominantly diagonal sequence (DS) gait of nonhuman primates. However, these studies neglected possible sex-related differences in these gait types. OBJECTIVES: (1) To assess the possible sex-related gait types in UTS cases, healthy infants and adults with requested QL, and the nonhuman primates...

Elder populations have been increasing in Japan and estimated 24 million people have knee osteoarthritis(OA). Recently, people have diverse sociological background and demand for participating sports has been growing. People may participate sports to prevent some diseases such as locomotive syndrome. According to the recent studies, excessive high impact sports increase the risk of OA, while daily life exercise decrease the risk. Epidemiological approach demonstrated that reduced knee extension muscle strength increases the risk of OA...
