In this paper, fabrication of silicon microchannels with integrated obstacles by using 25 wt.% tetramethylammonium hydroxide (TMAH) aqueous solution at the temperature 80?C is presented and analysed. We studied basic island patterns, which present union two symmetrical parallelograms sides along predetermined crystallographic directions <n10> (2<n<8) <100>. Acute angles were s...

BACKGROUND AND PURPOSE Acute ischemic stroke patients with large volumes of severe hypoperfusion (Tmax>10 s>100 mL) on magnetic resonance imaging have a higher likelihood of intracranial hemorrhage and poor outcomes after reperfusion. We aim to evaluate the impact of the extent of Tmax>10 s CTP lesions in patients undergoing successful treatment. METHODS Retrospective database review of endov...

BACKGROUND In acute ischemic stroke the status of collateral circulation is a critical factor in determining outcome. We propose a less invasive alternative to digital subtraction angiography for evaluating collaterals based on dynamic-susceptibility contrast magnetic resonance imaging. METHODS Perfusion maps of Tmax and cerebral blood flow (CBF) were created for 35 patients with baseline occ...

OBJECTIVES To investigate the effect of cadence selection during the final minutes of cycling on metabolic responses, stride pattern, and subsequent running time to fatigue. METHODS Eight triathletes performed, in a laboratory setting, two incremental tests (running and cycling) to determine peak oxygen uptake (VO2PEAK) and the lactate threshold (LT), and three cycle-run combinations. During ...

This paper presents a comprehensive analysis of the effect urbanization on surface air temperature (SAT) from 1951 to 2018 in Philippines. The daily minimum (Tmin) and maximum (Tmax) records 34 meteorological stations were used derive extreme indices. These then classified as urban or rural based satellite night-lights. results showed significant difference SAT trends between stations, indicati...

Air temperature (Tair) near the ground surface is a fundamental descriptor of terrestrial environment conditions and one of the most widely used climatic variables in global change studies. The main objective of this study was to explore the possibility of retrieving high-resolution Tair from the Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST) products, cove...

BACKGROUND AND PURPOSE The recent thrombectomy trials have shown that perfusion imaging is helpful in proper patient selection in thromboembolic stroke. In this study, we analyzed the correlation of pretreatment Tmax volumes in MR and CT perfusion with clinical outcome after thrombectomy. METHODS Forty-one consecutive patients with middle cerebral artery occlusion (MCA) or carotid T occlusion...

BACKGROUND Gastrointestinal side effects, particularly diarrhea, are still the main reasons for discontinuation of enteral nutrition. Gelatinization of liquid meal for the prevention of diarrhea has been reported as effective. The purpose of this study was to investigate the effects of gelatinization of liquid meal on gastric emptying. METHODS Ten healthy volunteers were studied two times, wi...

The effect of creatine (Cr) supplementation on muscle isometric torque generation and relaxation was investigated in healthy male volunteers. Maximal torque (Tmax), contraction time (CT) from 0.25 to 0.75 of Tmax, and relaxation time (RT) from 0.75 to 0.25 of Tmax were measured during 12 maximal isometric 3-s elbow flexions interspersed by 10-s rest intervals. Between the pretest and the postte...

BACKGROUND AND PURPOSE The durations of acute ischemic stroke patients' CT or MR perfusion scans may be too short to fully sample the passage of the injected contrast agent through the brain. We tested the potential magnitude of hidden errors related to the truncation of data by short perfusion scans. MATERIALS AND METHODS Fifty-seven patients with acute ischemic stroke underwent perfusion MR...
