Use of nanoparticles in capillary and microchip electrochromatography

Applications of nanoparticles are of rising interest in separation science, due to their favorable surface-to-volume ratio as well as their applicability in miniaturization. A stationary phase with large surface area in combination with an electroosmotic flow-driven system has great potential in a highly efficient separation system. This review covers the use of various nanoparticles as stationary

Tender or not tender: Test-retest repeatability of pressure pain thresholds in the trapezius and deltoid muscles of healthy women

Objective: To examine the test-retest repeatability of pressure pain thresholds in the shoulder muscles of healthy women. Design: Four experimental sessions (days 1, 3, 28, 30), each including 4 consecutive pressure pain threshold measurements at 10-minute intervals. Subjects: Twenty-four healthy female volunteers, mean age 42 years. Methods: Two examiners measured pressure pain thresholds bilater

Hög tid att pröva hypotermi i behandlingen av slaganfall

There is a revived clinical interest in hypothermia as a neuroprotective intervention in brain ischemia. This originates from the experimental finding that hypothermia of only 3 degrees C-4 degrees C below normal body temperature completely abolishes neuronal damage from an ischemic insult that is lethal in normothermia. The idea that hypothermia protects cells from ischemic damage mainly by lower

A study of exercise-induced microalbuminuria in type I (insulin-dependent) diabetes mellitus

Microalbuminuria is thought to be an important prognostic factor in diabetes mellitus. To study the influence of changes in blood pressure on the development of microalbuminuria during exercise, two exercise tests were carried out. A total of 32 insulin dependent diabetic men whose age at onset was less than 30 years, mean duration of diabetes 14 years (range 7 to 21) and mean age 29 years (range

Effect of alpha-ketoglutarate (AKG) on mineralisation, morphology and mechanical endurance of femur and tibia in turkey

The aim of this study was to determine the influence of alpha-ketoglutarate (AKG) on volumetric bone density, geometrical and mechanical properties of femur and tibia in farm turkeys. All animals were kept under standard rearing conditions with constant access to water and appropriate feed, supplied in accordance with the stage of production cycle. Bone samples were collected 14 weeks after beginn

Corneal surface changes in keratoconjunctivitis sicca. Part I: the surface proper. A non-contact photomicrographic in vivo study in the human cornea

Purpose To describe corneal surface changes in keratoconjunctivitis sicca (KCS). Methods In all 23 patients with KCS were examined with the slit lamp and photographed by non-contact photomicrography. Results Without staining, grey surface cells and small epithelial cysts were visible. Application of fluorescein sodium resulted in two types of micropunctuate (15-30 mum) staining, a nonfluorescent (

Abstract in German Durch ihren übergreifenden Zeitrahmen verweilt die Autorin nicht bei einer spezifischen historischen Situation, sondern bettet die Sibelius-Rezeption in einen größeren Kontext ein. Der Titel schränkt daher den Blickwinkel unnötig ein, da sich fast ¼ der Arbeit nicht mit der NS-Zeit beschäftigt, sondern als notwendiges Korrelat zur NS-Rezeption auch die Nachkriegszeit bis in die

Multispecies trapping of six pests of scots pine in Sweden and Poland

Multispecies sex pheromone trapping (trapping of more than one species in the same trap) for the pine shoot moth Rhyacionia buoliana , the pine moth, Dendrolimus pini , the nun moth, Lymantria monacha , the pine beauty moth, Panolis flammea and the pine sawflies Diprion pini and Neodiprion sertifer was evaluated. The catch from traps baited with the pheromone of a single species was compared with

Selective removal of 17 beta-estradiol at trace concentration using a molecularly imprinted polymer

A molecularly imprinted polymer (MIP) was synthesized with 17 beta-estradiol (E2) as template. It was then capable to recover this compound by 100 +/- 0.6% from a 2 mu g/L aqueous solution. By comparison, E2 recoveries of 77 +/- 5.2%, 87.1 +/- 2.3% and 19.1 +/- 7.8%, were achieved using a non-imprinted polymer (NIP) synthesized under the same conditions (but without template), a commercial C18 ext
