• Capillary electrophoresis is well adapted for amino acids analysis. associated to fluorescence results in nanomolar concentration detections. conductimetry able be used most applications. mass spectrometry a very useful tool metabolomic Enantio-separations of are easily obtained using capillary electrophoresis.

A 41-year-old man was referred to our outpatient department with a diagnosis of urticaria with angioedema of 3 months duration. On examination, he had generalized coalescent waxy papules and diffuse periorbital swelling. Systemic examination was unremarkable except for limited finger flexion. Serum electrophoresis and thyroid function tests were normal. Histopathological examination showed norm...

Amyloidosis is an uncommon disease that results from the extracellular deposition of abnormal fibrillary protein. This paper reports a case of primary amyloidosis with predominant involvement of the gastrointestinal tract and heart as a mimicker of Crohn's disease in a sixty-seven years old man admitted with repeated diarrhea and fatigue. This patient poorly responded to 5-aminosalicylic acid a...

The protein bodies in maize endosperm are the sites of zein deposition. They are single membrane-bound vesicles with polysomes associated with the exterior surface of the membrane. These protein bodies were isolated by sucrose density gradients and characterized by electron microscopy and polyacrylamide gel electrophoresis. Polyribosomes dissociated from the surface of the membrane by detergent...

OBJECTIVE To assess the quantity and nature of the proteins that adsorb to hydrocephalus shunt catheters after implantation, and to determine whether sufficient could accumulate to obstruct the catheter. DESIGN Elution of proteins from 102 explanted shunt catheters, with protein assay and electrophoresis of the eluate, and scanning electron microscopy (SEM) of the catheters. RESULTS The amo...

Owing to its excellent semiconducting and photoelectronic properties, TiO2 has recently attracted a great deal of interest for a large variety of applications. Examples include the use of TiO2 nanoparticles/films as photocatalysts for environment protection, photoelectron mediators for sensors, photosensitizers in light-emitting devices, and solar cells. With the recent development in nanoscien...

BACKGROUND AND OBJECTIVES Membranoproliferative glomerulonephritis (MPGN) is an immune complex-mediated glomerulonephritis characterized by subendothelial and mesangial deposition of immune complexes. Autoimmune diseases and chronic infections, such as hepatitis C, are commonly recognized causes of MPGN; however, monoclonal gammopathy is a less widely recognized cause of MPGN. DESIGN, SETTING...

Parkinson's disease is a neurodegenerative disorder characterized by oxidative stress and CNS iron deposition. Ceruloplasmin is an extracellular ferroxidase that regulates cellular iron loading and export, and hence protects tissues from oxidative damage. Using two-dimensional electrophoresis, we investigated ceruloplasmin patterns in the CSF of human Parkinson's disease patients. Parkinson's d...

Colloidal particles in electrolytes move in response to electric fields !electrophoresis" and salt concentration gradients !diffusiophoresis", and related flows also occur at fixed surfaces !electro-osmosis and diffusio-osmosis, respectively". In isolation, these electrokinetic phenomena are well understood, e.g., electrophoresis without far-field concentration gradients and diffusiophoresis wi...
