Arterial compliance is found to be reduced in haemodialysis patients. It is not clear whether decreased arterial compliance in uraemic patients is a consequence of long-standing increased mean arterial blood pressure or a consequence of the uraemic state. An adequate blood pressure can be achieved by long-treatment-time dialysis of 8 h three times a week. We studied femoral and carotid artery w...

The Kell blood group system is complex, contains many antigens, highly immunogenic, and potent in triggering immune reactions. Antibodies to Kell blood group system are the most common immune red cell antibodies, following ABO and Rh. However, among the anti-Kell antibodies; anti-Kpa is extremely rare. We report an interesting case of Anti-Kpa in a 59-year-old female patient of Non-Hodgkin's Ly...

Pyroxene is the principal host of Fe 3+ in basalt source regions, hosting 79 and 81% spinel garnet lherzolite, respectively. In peridotite, orthopyroxene (opx) clinopyroxene (cpx) 48% 31%, respectively, total . Yet relationship between mantle mineralogy, pyroxene chemistry, oxygen fugacity ( f O2 ) recorded by mantle-derived basalts remains unclear. To better understand partitioning melt we con...

The super-saturation condition has to be provided to form gas hydrates. Consequently, the prediction of the guest molecule fraction in the aqueous phase is crucial in the study of the gas hydrate kinetics. In the present work, several experiments were carried out in a semi-batch reactor in order to determine the mole fraction of methane and ethane during gas hydrates formation (growth stage...

The axial and radial compressive moduli of the human meniscus are important material properties in tibiofemoral joint models, but they have not been determined previously for fresh-frozen tissue. Our goals were to measure the moduli at equilibrium and at a physiological strain rate, to determine whether the axial and radial compressive moduli are equal for each type of loading, and to determine...

PURPOSE To evaluate and compare the performance of shear-wave elastography (SWE) for breast masses using the local shear wave speed (m/sec) vs. Young modulus (kPa). METHODS A total of 130 breast lesions in 123 women who underwent SWE before ultrasound- guided core needle biopsy or surgical excision were included. With the region-of-interest placed over the stiffest areas of the lesion on SWE,...

The arterial oxygen tensions (Pa,02) in chronic obstructive pulmonary disease (COPD) patients travelling by air, should, according to two different guidelines, not be lower than 7.3 kPa (55 mmHg) and 6.7 kPa (50 mmHg), respectively, at a cabin pressure altitude of 2,438 m (8,000 ft). These minimum in-flight Pa,O2 values are claimed to correspond to a minimum Pa,O2 of 9.3 kPa (70 mmHg) at sea-le...

Riboflavin/UVA-induced corneal collagen cross-linking has become an effective clinical application to treat keratoconus and other ectatic disorders of the cornea. Its beneficial effects are attributed to a marked stiffening of the unphysiologically weak stroma. Previous studies located the stiffening effect predominantly within the anterior cornea. In this study, we present an atomic force micr...

Strawberry fruit, western flower thrips and two-spotted spider mites were exposed to a range of ethyl formate (EF) concentrations from 0.8 to 2.4%. Ethyl formate treatments included both single and multiple applications of EF, the multiple applications having a venting period between each application. Additionally, target pests were exposed to EF and elevated levels of CO2 from 5 to 95 kPa, bal...
