ataxia/hypoxia

Chk2 is a serine/threonine kinase that signals to cell cycle arrest, DNA repair, and apoptotic pathways following DNA damage. It is activated by phosphorylation in response to ionizing radiation, UV light, stalled replication forks, and other types of DNA damage. Hypoxia is a common feature of solid

A 76-year-old HTLV-I-positive male with acute cerebellar ataxia was suffering from dyspnea on exertion. Chest CT suggested interstitial pneumonitis. Methylprednisolone pulse therapy improved his symptoms and chest CT findings. Twelve months after discharge, when the prednisolone dose was tapered to

OBJECTIVE To establish a simple measure of ataxia for use at high altitude. METHODS Twenty healthy subjects took part in a trek to 5005 m. At 5 different altitudes on the route, they undertook a balance test using a wobble board. The primary objectives were to investigate disturbances of ataxia at

Hypoxic stress activates various signal transduction pathways including posttranslational modification with the ubiquitin-like SUMO protein (SUMOylation). However, the molecular mechanisms by which SUMOylation regulates hypoxic responses remain unclear. Here, we investigated the ability of rat

Hypoxia in aviation remains a major hazard. It may be caused by ascent while breathing air, failure of oxygen supply or loss of cabin pressurisation. Malfunction of equipment or its improper use accounted for the majority of hypoxic incidents in one 10-year military study. Symptoms of hypoxia depend

Friedreich's Ataxia (F.A.) is a degenerative disease which commonly leads to premature death of cardiorespiratory origin. To explain the early death of these patients, previous investigations have established the existence of 1) a cardiomyopathy in nearly 100% of cases, 2) a restrictive pulmonary

Stability of stance declines at high altitude in subjects with and without acute mountain sickness (AMS), suggesting that postural ataxia might result from different hypoxia-related mechanisms than those causing the signs and symptoms of AMS. The aim of this study was to determine whether short-term

The practice of inhaling liquefied petroleum gas (LPG) to commit suicide is uncommon and almost exclusively a prerogative of the prison population. Numerous cases of sudden deaths caused by intentional propane and/or butane inhalation have been described, but these cases survived and a description

Most adolescents with ataxia telangiectasia (A-T) develop progressive bulbar muscle weakness and decreased pulmonary reserve. The purpose of this study was to define the patterns of sleep and respiration during sleep, and to identify sleep-related breathing problems in subjects with A-T. To address

A 26-year-old woman suffered disseminated intravascular coagulation (DIC) and a brief respiratory arrest following recreational use of 3,4-methylene-dioxymethamphetamine (MDMA; 'ecstasy'), together with amyl nitrate, lysergic acid (LSD), cannabis and alcohol. She was left with residual cognitive and

The association of truncal ataxia with a number of different factors has been studied in a group of 95 epileptic outpatients on chronic anticonvulsant treatment. The 28 patients showing truncal ataxia had been epileptic for a longer period of time, received a significantly larger number of drugs,

The DNA-damaging agent camptothecin (CPT) and its analogs demonstrate clinical utility for the treatment of advanced solid tumors, and CPT-based nanopharmaceuticals are currently in clinical trials for advanced kidney cancer; however, little is known regarding the effects of CPT on hypoxia-inducible

Retinoic acid-receptor-related orphan receptor (ROR) alpha is a nuclear receptor involved in many pathophysiological processes such as cerebellar ataxia, inflammation, atherosclerosis and angiogenesis. In the present study we first demonstrate that hypoxia increases the amount of Rora transcripts in

OBJECTIVE To study whether laryngeal cancer stem cells in hypoxia have the characteristic of resistance to irradiation and underlying mechanism. METHODS CD133(+) cells were separated from Hep-2 cells with flow cytometry (FCM) and the purity was 92.8%. The separated CD133(+) cells were cultured in
