Faculty of Health Sciences, University of Macau, Avenida de Universidade, Taipa, Macao Special Administrative Region of China. Electronic address:

With the advancements of next-generation sequencing, publicly available pharmacogenomic datasets from cancer cell lines provide a handle for developing predictive models of drug responses and identifying associated biomarkers. However, many currently available predictive models are often just used as black boxes, lacking meaningful biological interpretations. In this study, we made use of open-source drug response data from cancer cell lines, in conjunction with KEGG pathway information, to develop sparse neural networks, K-net, enabling the prediction of drug response in EGFR signaling pathways and the identification of key biomarkers.

Background: Current neurovascular unit isolation requires processing brain microvascular endothelial cells (BMECs) and neurons from separate animals, preventing concurrent analysis of neurovascular crosstalk within identical genetic/physiological contexts.

New Methods: We developed an enzymatic digestion/bovine serum albumin density gradient technique that enables the simultaneous isolation of neural tissue and microvascular segments from individual mice. The neural tissue was filtered and centrifuged for primary cortical neuron culture on poly-L-lysine-coated plates.

With the aging process, older adults performed significantly poorer than young adults at remembering the relationships between pieces of information. This phenomenon is known as age-related associative memory deficit. Associative Deficit Hypothesis posits that this deficit stems from hippocampal atrophy in older adults, leading to a decline in their ability to bind information and an impairment in hippocampus-dependent recollection.

Org Lett

September 2025

State Key Laboratory of Precision and Intelligent Chemistry, Department of Chemistry, University of Science and Technology of China, Hefei 230026, P. R. China.

A novel palladium-catalyzed asymmetric aminomethylative pyridonation of conjugated dienes with -acetals and 2-hydroxypyridines was established, which provided a direct and reliable method for the synthesis of a wide range of γ-aminated N-substituted 2-pyridones with good to excellent enantioselectivities. The simple BF was identified as an effective cocatalyst to improve the reaction efficiency, and DFT calculations revealed that proton transfer between the aminomethylated allylic palladium species and 2-hydroxypyridine promoted by BF is crucial for obtaining good reactivity.

Early diagnosis of Alzheimer's disease (AD) is hindered by the high cost, complexity, and centralization of current diagnostic platforms such as enzyme-linked immunosorbent assay (ELISA) and single-molecule array (SIMOA). Here, an integrated point-of-care (PoC) biosensing platform is reported based on redox-active polyphenol red molecularly imprinted polymers (pPhR MIPs) deposited on highly porous gold (HPG) electrodes for the ultrasensitive, reagent-free detection of phosphorylated tau 181 (p-tau 181) in undiluted plasma and serum. The unique electrochemical interface combines the signal-enhancing properties of HPG with the redox functionality of pPhR, eliminating the need for external redox probes.

Chemical doping has emerged as a powerful approach for modulating the electronic properties of graphene, and particularly for enabling its integration into advanced electronic and optoelectronic devices. While considerable progress has been made in achieving stable p-type doping, realizing efficient and reliable n-type doping remains a greater challenge due to the inherent instability of most electron-donating dopants and intrinsic semi-metallic nature of pristine graphene. This review summarises the recent developments in n-type chemical doping of graphene films, with a primary focus on substitutional doping and surface charge transfer mechanisms.
