Their structures were established on the basis of chemical and spectroscopic approaches. These compounds were assessed for their therapeutic effects on diabetic nephropathy (DN)-evoked fibrosis through High-Glucose and transforming growth factor-β1 (TGF-β1) challenged HK-2 cells. Among them, compounds 3, 5 and 8 could remarkedly decrease the level of fibronectin to relieve DN with 27.66 ± 2.77%, 6.09 ± 0.57% and 17.74 ± 5.83% inhibition rate at 10 μM, 10 μM and 1 μM, respectively. To investigate whether hearing difficulties exacerbate the damaging effects of enforced social distancing due to the COVID-19 pandemic on isolation and loneliness, and lead to accelerated mental health issues and cognitive dysfunction. Rapid online survey. Participants completed a series of online questionnaires regarding hearing ability, socialisation (pre- and during-pandemic), loneliness, anxiety, depression and cognitive function. A total of 80 participants over the age of 70 with access to the internet. There was a significant reduction in socialisation levels from pre-pandemic in this population. Hearing difficulties were significantly associated with greater levels of loneliness, depression and self-perceived cognitive dysfunction after controlling for age, gender, and level of education. Additionally, compared to pre-pandemic, people with hearing difficulties had increased odds of reporting worsened anxiety, depression, and memory during the COVID-19 pandemic, although only the effect of hearing difficulties on the change in memory reached statistical significance after controlling for age, gender, and level of education. The worse the self-reported hearing abilities are, the greater the negative impact of enforced social distancing on dep
