Background: Effective early intervention of mild cognitive impairment (MCI) is the key for preventing dementia. However, there is currently no drug for MCI. As a multi-targeted neuroprotective agent, butylphthalide has been demonstrated to repair cognition in patients with vascular cognitive impairment, and has the potential to treat MCI due to Alzheimer's disease (AD).

Background: The effects of the COVID-19 pandemic extend beyond the viral impact and include social and psychological effects of the ensuing lockdowns and restrictions. Australia's lengthy lockdowns present an opportunity to study changes in the physical and mental wellbeing of older adults resulting from extended social isolation, a known risk factor for dementia, in the absence of high infection or mortality rates.

Method: Sydney Memory and Ageing Study, Sydney Centenarian Study, and CogSCAN study participants were mailed questionnaires about in-person and remote social contact and access to resources during the 2020 Sydney lockdown.

As a putative lung specific oncogene, the transducin-like enhancer of split 1 (TLE1) corepressor drives an anti-apoptotic and pro-epithelial-mesenchymal transition (EMT) gene transcriptional programs in human lung adenocarcinoma (LUAD) cells, thereby promoting anoikis resistance and tumor aggressiveness. Through its survival- and EMT-promoting gene regulatory programs, TLE1 may impact drug sensitivity and resistance in lung cancer cells. In the present study, a novel function of TLE1 was uncovered as an inhibitor of the antitumor effects of the epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) gefitinib in the human LUAD cell line A549, which exhibits moderate sensitivity to EGFR-TKI.
