BACKGROUND
Deep oceans have been suggested as a possible site where the origin of life occurred. Along with this theoretical lineage, experiments using components from deep ocean water to recreate life is underway. Here, we propose that if terrestrial organisms indeed evolved from deep oceans,
OBJECTIVE
Recent studies have investigated the importance of recovery strategies after training session, including hydrotherapy and cryotherapy. However, only a few studies have focused on cold-water immersion (CWI) treatments in team sport disciplines. The present study investigates the effects of
OBJECTIVE
The purpose of this study was to determine enamel and dentin bond durability after long-term water storage using self-etch adhesives.
METHODS
Two single step self-etch adhesives (SU, Scotchbond Universal and GB, G-ӕnial Bond) and a two-step self-etch adhesive (OX, OptiBond XTR) were used.
Hemodialysis patients (HD) commonly report fatigue. Muscle wasting (sarcopenia) and extracellular water (ECW) excess have been reported to be associated with fatigue in other conditions. We wished to determine whether muscle loss and ECW excess were associated with fatigue in HD patients. Patients
Muscle fatigue - defined as impaired contractility - coincided in rat skeletal muscle during in vitro experiments with a decrease in intracellular potassium concentration, [K], and a decrease in resting membrane potential, RMP. In man changes in intra- and extracellular electrolyte concentrations
Water metabolism and the responses of the neurohypophysis to changes in plasma osmolality during the water loading and water deprivation tests were studied in nine patients with postviral fatigue syndrome (PVFS) and eight age and six-matched healthy control subjects. Secretion of
Superwetting materials emerge distinct advantages in interfacial applications such as oil-water separation. However, it remains a challenge to solve water-accelerated fatigue of lubricating oil owing to the poor mechanical durability of superhydrophobic surfaces and the intractable emulsions
Haemodialysis is frequently complicated by side-effects both during and after treatment. Hypotension and muscle cramps have been attributed to depletion of intravascular volume; headache and fatigue have been attributed to rapid changes in intracellular and extracellular osmolality. An
Chronic fatigue syndrome, infection and oxidative stress are interrelated in epidemiological case studies. However, data demonstrating scientific validation of epidemiological claims regarding effectiveness of nutritional supplements for chronic fatigue syndrome are lacking. This study is designed
Chronic fatigue syndrome (CFS) is a specific clinical condition that characterizes unexplained disabling fatigue. In the present study, chronic fatigue was produced in mice by subjecting them to forced swim inside a rectangular jar of specific dimensions for 6 min. daily for 15 days.
Physical fatigue is extremely common and occurs daily, and is considered to be associated with oxidative stress. The diverse functions of deep sea water (DSW) have recently gained increasing attention. Previous studies have emphasized the anti-fatigue effect of DSW, but the intrinsic mechanism
Okra, Abelmoschus esculentus (L.) Moench, an annual herbaceous plant, is widely distributed in tropical and subtropical regions. Water-soluble pectic hydrocolloids from okra stems (HOS) were extracted and purified using polydivinylbenzene HP-20 resins. The sugar composition of the purified HOS with
OBJECTIVE
Panax ginseng C. A. Meyer (ginseng) is a well-known Chinese herb often used in Asian countries for physical strength development. Ginseng polysaccharides are its active component and have a lot of pharmaceutical activities. However, anti-fatigue activity of ginseng polysaccharides has not
Although Giardia lamblia cysts are an important contaminant of surface water supplies, only one swimming pool outbreak, involving an infant and toddler swim class, has been reported. We describe an outbreak of giardiasis associated with a hotel's new water slide pool which was cleansed by both
Dehydration impairs physiological function and physical performance, thus understanding effective rehydration strategies is paramount. Despite growing interest in natural rehydrating beverages, no study has examined maple water (MW).To investigate the
