The development of noninvasive approaches to precisely control neural activity in mammals is highly desirable. Here, we used the ion channel transient receptor potential ankyrin-repeat 1 (TRPA1) as a proof of principle, demonstrating remote near-infrared (NIR) activation of endogenous neuronal channels in mice through an engineered nanoagonist. This achievement enables specific neurostimulation in nongenetically modified mice.

Previous studies in small samples have identified inconsistent cortical abnormalities in major depressive disorder (MDD). Despite genetic influences on MDD and the brain, it is unclear how genetic risk for MDD is translated into spatially patterned cortical vulnerability. Here, we initially examined voxel-wise differences in cortical function and structure using the largest multi-modal MRI data from 1660 MDD patients and 1341 controls.

July 2024

Department of Oral Medicine, the Affiliated Hospital of Yunnan University (Second People's Hospital of Yunnan Province, Yunnan Province Ophthalmology Hospital), Kunming 650031, Yunnan, China.

Article Synopsis
  • The study investigates how long noncoding RNA HCP5 from human bone marrow mesenchymal stem cells (hBMMSCs) influences the osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) to combat chronic periodontitis (CP).
  • Researchers used various techniques like RT-qPCR and staining to measure the expression of osteogenic markers and analyze the effects of HCP5 on hPDLSCs and in CP mice.
  • Results showed that HCP5 boosts the osteogenic potential of hPDLSCs, while its knockdown leads to increased inflammation and decreased bone formation in CP, suggesting a regulatory role through interactions with miR-24-3p.

Objective: Mucinous breast cancer (MBC) is a kind of breast cancer (BC), which is rare in clinic, mainly for women, because of the low incidence rate, so there is no unified standard treatment protocol. Elderly patients have a poor prognosis due to their combined comorbidities. This study aims to investigate the effect of surgery and chemoradiotherapy on the prognosis of elderly female MBC patients and construct nomograms for predicting the OS and CSS in elderly female MBC patients.
