25-Hydroxyvitamin D serum levels inversely correlate to disease severity and serum C-reactive protein levels in patients with hidradenitis suppurativa by Moltrasio, Chiara

“…Vitamin D exerts functions in skin physiology by modulating keratinocyte proliferation and different immunoregulatory processes.1 In several dermatoses, vitamin D correlates to disease severity and is significantly lower if compared to healthy subjects.2 Hidradenitis suppurativa (HS) is a chronic inflammatory disease characterized by painful suppurating lesions mainly localized in the folds.3 Kelly et al.4 conducted the first study assessing vitamin D status in HS, concluding that 75% of patients had vitamin D levels of less than 50 nmol/L compared to 40% of the general population. …”

Tailoring of the thermal, mechanical and dielectric properties of the polypropylene foams using gamma-irradiation by Mrl�k, Miroslav

“…Investigated mechanical properties in case of tensile tests as well as dynamical mechanical analysis proved, that enhanced behaviour was observed only in case of samples with irradiated by low doses, 1 kGy and 5 kGy, respectively, while the higher doses significantly decrease these ones, due to the present scission confirmed by FTIR and other investigations. …”
