Historically, head and neck injuries constituted 16 to 20% of all nonfatal combat injuries. However, advances in body and vehicle armor in the context of the use of ambushes and improvised explosive devices by enemy combatants have resulted in fewer fatalities from head and neck wounds, and thus the incidence of nonfatal head and neck injuries has risen to as high as 52%. Despite this increase, data regarding specific injury distributions, surgical cases, and approaches to repair are lacking in the current literature...

Computing with resistive-switching (memristive) memory devices has shown much recent progress and offers an attractive route to circumvent the von-Neumann bottleneck, i.e. the separation of processing and memory, which limits the performance of conventional computer architectures. Due to their good scalability and nanosecond switching speeds, carbon-based resistive-switching memory devices could play an important role in this respect. However, devices based on elemental carbon, such as tetrahedral amorphous carbon or ta-C, typically suffer from a low cycling endurance...

PURPOSE: No previous study has explored the importance of exercise-induced changes in vascular function to prolonged adaptations. Therefore, the purpose was to explore the within-subject relationship between the acute post-exercise change in brachial artery endothelial function (flow-mediated dilation, FMD) and the change in resting FMD after a 2-week exercise training in healthy volunteers. METHODS: Twenty one healthy, young men (24 ± 5 years) underwent assessment of brachial artery FMD using high-resolution ultrasound before and after 30-min of moderate-intensity cycle exercise (80% maximal heart rate)...

We studied the effects of various assay temperatures, representing hypothermia (25°C), normothermia (35°C), and hyperthermia (42°C), on the oxidation of lipid-derived fuels in rat skeletal muscle mitochondria of untrained and endurance-trained rats. Adult 4-month-old male Wistar rats were assigned to a training group (rats trained on a treadmill for 8 weeks) or a sedentary control group. In skeletal muscle mitochondria of both control and trained rats, an increase in the assay temperature from 25°C to 42°C was accompanied by a consistent increase in the oxidation of palmitoylcarnitine and glycerol-3-phosphate...

Aging gradually renders bone marrow hematopoietically inactive. Endurance exercise reverses this phenotype in young mice. Here, we determine the effects in aged mice. Twenty-two month old mice (n=6) underwent a progressive exercise training protocol. In appendicular bones, marrow cellularity increased by 51% (p<0.05) and marrow CFU, CFU-GM, and CAFC increased by 12%, 71%, and 86%, respectively (p<0.05). Vertebral cellularity remained unchanged. The mechanical forces associated with treadmill exercise training may be responsible for these observations...

PURPOSE: Restoring skeletal muscle and hepatic glycogen content during short-term (<6 h) recovery from prolonged exercise is pertinent for athletes seeking to maximize performance in repeated exercise bouts. Previous research suggests co-ingestion of fructose-glucose carbohydrate sources augments hepatic and has equivalent effects on skeletal muscle glycogen storage during short-term recovery from prolonged exercise compared to isocaloric glucose ingestion. The aim of the present investigation was to determine if this has a discernible effect on subsequent exercise capacity...

In order to optimize the performance of silver nanowire (Ag NW) film heaters and explore the effect of graphene on the film, we introduced the poly (3, 4-ethylenedioxythiophene): poly (4-styrenesulfonate) (PEDOT: PSS) and graphene modified with ethyl cellulose (graphene-EC) into the film in this paper. The high quality and well-dispersed graphene-EC was synthesized with graphene obtained by electrochemical exfoliation as precursor. The transparent film heaters were fabricated via spin-coating. With the assistance of graphene-EC, the stability of the film heaters was greatly improved and the conductivity was optimized by adjusting Ag NW concentration...

OBJECTIVES: Orofacial dysfunctions (OFD) or orofacial myofunctional disorders in children lead to severe problems in teeth and jaw position, articulation, chewing and swallowing. The forces of the tongue, the central muscle for articulation, chewing and swallowing is focused on in several studies. In this examination, isometric tongue protrusion forces (TPF) of children with OFD and controls were compared. METHODS: 30 participants with OFD and 30 controls were presented a target force level as a straight line on a monitor that they were supposed to match by generating an isometric tongue force for different target levels (0...

Mitochondrial dysfunction and decreased mitochondrial content are hallmarks of aging that leads to decreased physical endurance. Our aim was to explore the anti-aging effect of resveratrol (RSVT) supplementation, a polyphenol, and/or exercise training, started at an older age, on improving physical activity, therefore, help in frailty avoidance and promotion of healthy aging in elderly. Eighteen-month-old aged mice received RSVT (15 mg/kg/day) and/or exercise trained for 4 weeks showed significant longer time to exhaustion with decreased blood lactate and free fatty acids levels associated with improved oxidative stress evidenced by decreased gastrocnemius muscle lipid peroxidation and increased antioxidant enzymes activities, catalase and superoxide dismutase, when compared to aged mice control group...

BACKGROUND AND AIMS: Research suggests swearing can moderate pain perception. The present study assessed whether changes in pain perception due to swearing reflect a "scripting" effect by comparing swearing as a response to pain in native English and Japanese speakers. Cognitive psychology denotes a 'script' to be a sequence of learnt behaviours expected for given situations. Japanese participants were included as they rarely, if ever, swear as a response to pain and therefore do not possess an available script for swearing in the context of pain...

The benefits of nitroglycerin are numerous, from ensuring accurate interpretation of diagnostic angiograms to treatment of coronary spasm and support of PCIs in simple or complex lesion types. The founders of the field were convinced that no coronary arteriography should be considered complete unless a vasodilator is used at some point during the study. This recommendation is valid. The guidelines should change to include administration of intracoronary nitroglycerin.

Pressure ulcers develop in patients who endure long periods of immobilization, often caused by conditions such as musculoskeletal and neurological diseases. Pressure ulcers adversely affect the patient and increase caregiver burden and healthcare costs. Typical sites for these ulcers include the sacrum, trochanters, and heels; they also occur on the nape of the neck, penis, nostrils, helix of the ear, and upper back. Compression stockings are commonly used to prevent and stop the progression of venous disorders, including deep vein thrombosis, but their role in the development of pressure ulcers is not well known...

In August 1990, Saddam Hussein's army invaded Kuwait and consequently the United Nations imposed economic sanctions on Iraq. In 1991, an international military alliance expelled the Iraqi army from Kuwait during a short war. Nevertheless, the economic sanctions remained in place-their removal required that Iraq should destroy its weapons of mass destruction. Subsequent years saw reports of acute suffering in Iraq. The sanctions undoubtedly greatly reduced the country's ability to import supplies of food and medicine...

Iron deficiency anaemia is a global health problem that manifests as fatigue and poor physical endurance. Anaemia can be caused by dietary iron deficiency, blood loss or a combination of poor iron absorption and ineffective iron mobilization in patients with chronic disease. Nephrologists caring for patients with impaired renal function understand that iron treatment is necessary to provide adequate iron for erythropoiesis during the treatment of overt anaemia. However, a less well-understood health problem is iron deficiency, which creates symptoms that overlap with those of anaemia and often occurs in concert with chronic disease...
