Some studies suggested a positive effect against cardiometabolic diseases of supplementation of alpha-linolenic acid (ALA, C18:3 n-3) rich foods in pathological subjects, even if the total literature is controversial. In order to clarify ALA-rich chia seed action in hypertensive model with the overt pathology and without drug interference, in the present study the biochemical markers of cardiometabolic diseases (endothelin-1, ET-1; nitric oxide, NO; and bradykinin, BK) in Spontaneously Hypertensive Rats (SHRs) were analysed after 5% chia seed dietary supplementation for five weeks, and compared with the staple raw material wheat and corn. At the end of the experimental period, also plasma antioxidant capacity and inflammatory condition were evaluated. Our results showed that the chia seed group was more oxidized. On the other hand, ET-1 significantly decreased in chia seed group, and there was no difference between groups for NO, BK, and the inflammatory C-reactive protein (CRP). In conclusion, some positive effects of chia seed consumption on cardiometabolic markers in SHRs were observed, despite this the association of chia seeds with antioxidants is suggested to avoid plasma oxidation increase.
Preparation of a Fe-mordenite catalysts was carried out by impregnation using Fe(acac)3 precursor in order to have iron oxide species deposited at the surface of the zeolite. The selective presence of iron oxide species was determined and ascertained by temperature programmed reduction (TPR). In the selective catalytic reduction of NO by ammonia, no difference of conversion between the catalysts was observed indicating that well dispersed iron oxide species are active species for this reaction. Nevertheless, the obtained activity remains lower than catalysts containing iron cationic species at the exchange sites.
