Autosomal dominant polycystic kidney disease - Type 2. Ultrasound, genetic and clinical correlations
(2000)Background. Ultrasound, genetic and clinical correlations are available for ADPKD-1, but lacking for ADPKD-2. The present study was carried out to address: (i) the age-related diagnostic usefulness of ultrasound compared ...

Bone pain in thalassaemia: assessment of DEXA and MRI findings
(1998)An increasing number of adult thalassaemics have been complaining of aches and pains of varying degrees of severity. In a minority the pains are debilitating and there is stiffness in movement. This study is an attempt to ...

Comparing Different Classifiers for Automatic Age Estimation
(2004)We describe a quantitative evaluation of the performance of different classifiers in the task of automatic age estimation. In this context, we generate a statistical model of facial appearance, which is subsequently used ...

The effect of aging and natural organic matter on the Th(OH)4 solubility
(2014)The solution chemistry of actinides, particularly hydrolysis, is of major importance in the design of nuclear waste repositories and in relation to nuclear fuel reprocessing cycles. In this study the formation and solubility ...

Embryonic multipotent progenitors remodel the Drosophila airways during metamorphosis
(2010)Adult structures in holometabolous insects such as Drosophila are generated by groups of imaginal cells dedicated to the formation of different organs. Imaginal cells are specified in the embryo and remain quiescent until ...

In vivo high-resolution magic angle spinning magnetic and electron paramagnetic resonance spectroscopic analysis of mitochondria-targeted peptide in Drosophila melanogaster with trauma-induced thoracic injury
(2016)Trauma is the most common cause of mortality among individuals aged between 1 and 44 years and the third leading cause of mortality overall in the US. In this study, we examined the effects of trauma on the expression of ...

In vivo high-resolution magic angle spinning magnetic resonance spectroscopy of Drosophila melanogaster at 14.1 T shows trauma in aging and in innate immune-deficiency is linked to reduced insulin signaling
(2010)In vivo magnetic resonance spectroscopy (MRS), a non-destructive biochemical tool for investigating live organisms, has yet to be used in the fruit fly Drosophila melanogaster, a useful model organism for investigating ...

Influence of oxychlorination treatments on the redox and oxygen storage and release properties of thermally aged Pd-Rh/CexZr1-xO 2/Al2O3 model three-way catalysts
(2005)Model Pd-Rh/Al2O3 three-way catalysts with and without CexZr1-xO2 as oxygen storage component have been compared in their fresh, thermally aged and oxychlorinated treated surface states to determine the potential regenerating ...

Measuring recent thymic emigrants in blood of normal and HIV-1-infected individuals before and after effective therapy
(1999)The role of the thymus in HIV-1 pathogenesis remains unclear. We developed an assay to quantify the number of recent thymic emigrants in blood based on the detection of a major excisional DNA byproduct (termed α1 circle) ...

Predictions of structure breakdown, buildup and shear banding in semisolid suspensions
(2008)When SSM material is subjected to a sudden transient the rate of buildup (aging) is negligible compared to the rate of breakdown (shear rejuvenation). While this is generally true, due to prolonged processing or the geometry ...

Proactive Risk-Based Integrity Assessment of Water Distribution Networks
(2010)Sustainable management of urban water distribution networks should include not only new methods for monitoring, repairing or replacing aging infrastructure, but also (and more importantly) expanded methods for modelling ...

Regulation of retinoid X receptor-γ gene transcript levels in rat heart cells
(1998)Retinoid X receptor-γ (RXRγ) is a transcription factor that mediates retinoid signalling and is expressed in rat heart during adult life. However, its expression in embryonic and neonatal heart has not been investigated ...

Ultrasound image texture analysis of the intima and media layers of the common carotid artery and its correlation with age and gender
(2009)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the composition and texture of ...
