Application of SPR Imaging Biosensor for the Measurement of 20S Proteasomes in Blood Plasma of Children with Thermal Injury.

Background: Determination of proteasome concentration in blood plasma in children with burns, with the Surface Plasmon Resonance Imaging biosensor.

Material And Methods: 35 children scalded by hot water, with burns in 4-20% TBSA were included into the study (age 9 months up to 14 years, mean age 2,5+1 years). Blood plasma 20S proteasome concentration was assessed in 2-6h, 12-16h, 3d, 5d, and 7d after injury using Surface Plasmon Resonance Imaging biosensor.

Ultrasound-guided percutaneous 'push-introducer' gastrostomy is a valuable method for accessing the gastrointestinal tract.

Percutaneous endoscopic gastrostomy (PEG) is the most effective and least invasive method for enteral nutrition (EN). The most common system for PEG is the 'pull' technique, which . It is not available in case endoscopy cannot be performed.

Expression of estrogen receptors α and β in paratesticular tissues in boys operated on for unilateral cryptorchidism between the 1st and 4th years of life.

Background: The aim of this study was to assess the expression of estrogen receptors alpha and beta in paratesticular tissues in a group of boys with and without cryptorchidism, and evaluation of karyotypes, localization, morphology and the major length of the undescended testes.

Material/methods: Fifty boys (1-4 years old) with unilateral cryptorchidism were evaluated. Fifty healthy boys within the same age range, with inguinal hernia, served as a control group.
