Expression of vascular remodelling markers in relation to bradykinin receptors in asthma and COPD
Background Vascular remodelling plays a central role in asthma and chronic obstructive pulmonary disease (COPD). Bradykinin (BK) is a vasoactive proinflammatory peptide mediating acute responses in asthma. We investigated the role of angiogenic factors in relation to BK receptors in asthma and COPD. Methods Bronchial biopsies from 33 patients with COPD, 24 old (50 years) patients with (50years) asthma, 18 old control smokers, 11 old control non-smokers, 15 young (40yrs) patients with (40years) asthma and 10 young control non-smokers were immunostained for CD31, vascular endothelial growth factor-A (VEGF-A), angiogenin and BK receptors (B2R and B1R). Fibroblast and endothelial co-localisation of relevant molecules were performed by immunofluorescence. BK-induced VEGF-A and angiogenin release was studied (ELISA) in bronchial fibroblasts from subjects with asthma and COPD. Results In bronchial lamina propria of old patients with asthma, CD31 and VEGF-A(+) cell numbers were higher than old control non-smokers (p Conclusions Unlike COPD, this study suggests the involvement of BK receptors in bronchial vascular remodelling in asthma

Oncoplastic and reconstructive surgery in SENONETWORK Italian breast centers: lights and shadows
: • Despite the significance of oncoplastic procedure, an italian database is lacking. • Senonetwork established a multidisciplinary survey to assess their safety and efficacy. • Reconstructive outcomes were positive across low and high-volume centers. • After mastectomy, implant-based techniques are common. DTI reconstruction is advantageuos. • This contributes to the global understanding of effective strategies against breast cancer
