The aim of our study was to assess in psoriatic patients the production of IL-8, IL-10 and IL-12 cytokines by neutrophils, fibroblasts and fibroblasts – neutrophils interaction.

Material/Methods: The production of IL-8, IL-10 and IL-12 cytokines was evaluated in supernatants after cells incubation for 21 h in culture medium alone and in medium in the presence of IL-8 or TNF-alpha. Concentrations of IL-8, IL-10, IL-12 were measured by enzyme-linked immunosorbent assay (ELISA) method AZD6738 in vivo using commercially available kits.

Results: Our results demonstrate

that fibroblasts are not able to produce IL-10 and IL-12 but they generate IL-8. The amount of IL-8 depends on the site of derivation of fibroblasts and on the stimuli. Neutrophils released IL-8, IL-12 (at a lower level in psoriatic patients) and IL-10 but only in the case of healthy donors and at a very low concentration. Moreover, we observed higher concentrations of IL-12 and IL-8 in supernatants as a result of fibroblasts-neutrophils interaction in psoriatic patients.

Conclusions: Our results suggest that fibroblasts take part in the inflammatory reaction in psoriasis via cytokines or direct interaction

with neutrophils. Fibroblasts probably do not exert any anti-inflammatory effect.”
“Intense exercise has been shown to have negative effects on systolic and diastolic ventricular function see more in adults. Very little is known about the normal reaction of the growing heart to

endurance stress. For this study, 26 healthy children (18 males) with a mean age of 12.61 years (range, 7.92-16.42 years) took part in an age-adapted triathlon circuit. The athletes were check details investigated by two-dimensional (2D) echocardiographic/speckle tracking, M-mode, pulse-wave Doppler, color Doppler, and color-coded tissue Doppler at 2-4 weeks before and immediately after the race. After the competition, cardiac output increased, mediated by an increase in heart rate and not by an elevated preload, according the Frank-Starling mechanism. Two-dimensional speckle tracking showed a reduced longitudinal strain in the right and left ventricles and additionally reduced circumferential strain in the left ventricle. The late diastolic inflow velocities were increased in both ventricles, indicating reduced diastolic function due to an impairment of myocardial relaxation. Immediately after endurance exercise, systolic and diastolic functions were attenuated in children and adolescents. In contrast to adult studies, this study could show a heart rate-mediated increase in cardiac output. The sequelae of these alterations are unclear, and the growing heart especially may be more susceptible to myocardial damage caused by intense endurance stress.”
