A specific exercise program targeting osteoporosis improves physical function capacity, reduces physiological bone loss, and maintains bone quality in low bone mineral density postmenopausal women.
The mono- and the digalactosyldiacylglycerol (MGDG and DGDG) galactolipids with a high content of polyunsaturated fatty acids, mainly omega-3, have been purified from the thermophilic blue-green alga ETS-05 that colonises the therapeutic thermal mud of Abano and Montegrotto, Italy. The therapeutic thermal mud is applied mostly to osteoarthritic cartilage patients. In the present study, a possible anti-inflammatory function of MGDG in cartilage has been studied in the avian articular cartilage model. We report that, in response to an inflammatory stimulus, adult avian articular cartilage cells express inflammation-related proteins, such as the lipocalin extracellular fatty acid binding protein, Avidin and Serum Amyloid A. The treatment of avian articular chondrocytes with the galactolipid MGDG suppressed the expression of the inflammation-induced proteins, suggesting a strong anti-inflammatory property of MGDG. MGDG has, in addition, a cell anti-proliferative activity, but it does not interfere with cell differentiation, suggesting a protective role for articular cartilage.
Background: Inhalation of thermal water (TW) is traditionally used as part of the treatment of chronic obstructive pulmonary disease (COPD), but its benefit and mechanisms are controversial. We previously observed a reduced proportion of neutrophils in induced sputum after treatment with TW. Objectives: The aim of this study was to determine whether inhalation of TW in COPD patients is associated with biochemical changes of airway lining fluid, including a reduction in the neutrophil chemoattractant leukotriene B4 (LTB4). Methods: Thirteen COPD patients were randomly assigned to receive a 2-week course of TW and normal saline inhalation in a cross-over, single-blind study design. Exhaled breath condensate (EBC) was collected before and after treatments. LTB4 concentrations in EBC were determined by ELISA, and EBC pH was measured before and after argon deaeration. Results: No significant differences in LTB4 concentrations in EBC were detected with either treatment. A significant decrease in pH of non-deaerated EBC was observed after a standard course of TW (median 7.45, interquartile range 6.93–7.66, vs. median 6.99, interquartile range 6.57–7.19; p = 0.05), which disappeared after argon deaeration. Conclusions: There is no evidence that TW treatment affects LTB4 concentration in EBC. The results of EBC pH measurements suggest that TW inhalation induces an imbalance of volatile components of the buffer system in airway lining fluid.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
