This review discusses the impact of recent publications on pathophysiologic concepts and on practical aspects of acute mountain sickness (AMS). Magnetic resonance imaging studies do not provide evidence of total brain volume increase nor edema within the first 6 to 10 h of exposure to hypoxia
The purpose of the present study is to survey the extraction conditions and explore the antioxidant potential of the wild herb Cistus incanus, which is non-traditional in Bulgarian ethnomedicine and widespread in the Strandja Mountain. The influence of the extraction time (0-500 min) and solvent
Mushrooms collected from Deogyu mountain, Korea, in 2011, were identified as four classes, four orders, 13 families, 22 genera, and 33 species. In particular, agaricales was most abundant and comprised more than 70%. Their antioxidant activities were estimated using three different bioassay methods,
The dried aerial parts of the mountain tea Sideritis euboea were extracted using n-hexane, methanol, diethyl ether, ethyl acetate, and n-butanol. The residues were tested for their antioxidant activity on sunflower oil at 50 degrees C under UV light. The oxidation of the sunflower oil was measured
OBJECTIVE
To assess associations between the stages of age-related maculopathy (ARM) and dietary intake of carotene, vitamin C, retinol, and zinc.
METHODS
Cross-sectional, population-based study.
METHODS
A total of 3654 subjects 49 years of age and older from a defined area, west of Sydney,
OBJECTIVE
The aim of the study was to examine oxidative responses in subarctic mountain birch, Betula pubescens subsp. czerepanovii, induced by herbivory and manual wounding.
METHODS
Herbivory-induced changes in polyphenoloxidase, peroxidase and catalase activities in birch leaves were determined. A
Acute mountain sickness; prophylactic benefits of Free-radical-mediated damage to the blood-brain barrier may be implicated in the pathophysiology of acute mountain sickness (AMS). To indirectly examine this, we conducted a randomized double-blind placebo-controlled trial to assess the potentially
OBJECTIVE
To investigate relationships between a wide range of macro- and micronutrients, including antioxidant vitamins, and the three main types of cataract in older people.
METHODS
Population-based cross-sectional study.
METHODS
Two thousand nine hundred people aged 49 to 97 years living in an
BACKGROUND
Fatness is an unwanted side effect of genetic selection in broiler chickens. In this study, we introduce mountain celery powder as a feed supplement to suppress lipogenesis and improve antioxidant status in broiler chickens. Male broiler chicks (Ross 308) were fed a control diet or a diet
Mountain celery seed essential oils (MC-E) contained 109 compounds, including mainly nine kinds of monoterpenoids, 31 kinds of of sesquiterpenoids, and 22 kinds of alcohols. A successive gel column adsorption with solvent fractionation yielded four fractionates. The pentane fractionate revealed
Physicochemical characteristics and anti-oxidant capacities of seeds from two farm-cultivated and one mountain-cultivated ginsengs (Panax ginseng Meyer) (MG) were determined. The seeds had 17.9-22.1% (dry basis) crude lipids, 11.5-15.2% crude proteins, and 1.4-1.7% ash. Oleic acid (77.9-78.5%) was
In this paper, a polysaccharide fraction (FMPS) was purified from the floral mushroom cultivated in Huangshan Mountain for the first time. Physicochemical properties and antioxidant activities of FMPS were investigated. FMPS had an average molecular weight of 7.2×10(5)Da and was composed of glucose.
OBJECTIVE
Multiple studies have explored pharmacologic interventions to prevent acute mountain sickness. A systematic review of this subject published in 2000 found that both acetazolamide and dexamethasone were effective. Since 2000, a number of other agents have been reported to be beneficial.
Pharmacotherapy in acute mountain sickness (AMS) for the past half century has largely rested on the use of carbonic anhydrase (CA) inhibitors, such as acetazolamide, and corticosteroids, such as dexamethasone. The benefits of CA inhibitors are thought to arise from their known ventilatory
Hypoxia, depending upon its magnitude and circumstances, evokes a spectrum of mild to severe acid-base changes ranging from alkalosis to acidosis, which can alter many responses to hypoxia at both non-genomic and genomic levels, in part via altered hypoxia-inducible factor (HIF) metabolism. Healthy
