Predictive risk factors for adverse events during tooth extraction among elderly patients with cardiovascular diseases.

Background: Tooth extraction is a risk factor for cardiovascular events, particularly in elderly patients. However, no clinical tool has been developed to date to predict the risk of adverse events (AEs) during tooth extraction.

Materials And Methods: We prospectively enrolled 774 elderly patients (aged ≥ 60 years) with cardiovascular disease (CVD) who were scheduled to undergo tooth extraction at the dental surgery department of Shanghai Ninth People's Hospital from January 2021 to July 2022.

Regulation of mineral elements in by under Cd stress.

In this study, wild barley () infected (E+) and uninfected (E-) by were used for hydroponic experiments during the seedling stage. Various attributes, such as the effect of fungal endophyte on the growth and development of wild barley, the absorption of cadmium (Cd) and mineral elements (Ca, Mg, Fe, Mn, Cu, Zn), subcellular distribution, and chemical forms were investigated under CdCl stress. The results showed that the fungal endophy significantly reduced the Ca content and percentage of plant roots under Cd stress.

Effect of Fungal Endophyte Infection on Cd Tolerance in Wild Barley ().

Hydroponic Hordeum brevisubulatum (wild barley) was used as material in the greenhouse to study the effects of endophyte infection on plant growth, Cd absorption and transport, subcellular distribution, and Cd chemical forms under CdCl2 stress. Endophytic fungi respond positively to chlorophyll content and photosynthetic efficiency under Cd stress. The order of Cd absorption in different parts of the plant was: roots > stems > leaves.
