An Automated Micro‐Immunobeads‐Based Electromagnetic Operation System (MEMOs) for Blood Testing of Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
This work presents an automated and accessible point‐of‐care device, MEMOs, for the detection of exosomal Aβ42 protein, a potential blood biomarker for Alzheimer’s disease. MEMOs, with its automated operation workflow, minimizes hands‐on time and maintains high sensitivity in diagnosing AD, allowing non‐specialists to conduct tests at home and offering

Rigid Macrocycle Metal Complexes as CXCR4 Chemokine Receptor Antagonists: Influence of Ring Size

open access: yesPharmaceutics
Understanding the role of chemokine receptors in health and disease has been of increasing interest in recent years. Chemokine receptor CXCR4 has been extensively studied because of its defined role in immune cell trafficking, HIV infection, inflammatory

A Minimally Invasive Framework Reveals Region‐Specific Cerebrovascular Remodeling in Aging Using Intravital Functional Ultrasound Imaging and Ultrasound Localization Microscopy (fUS‐ULM)

open access: yesAdvanced Science, EarlyView.
A high‐resolution intravital imaging platform combining functional ultrasound and localization microscopy enables longitudinal, minimally invasive assessment of cerebrovascular function in aging studies. The present investigation reveals aging‐related reductions in neurovascular coupling, arteriole‐to‐venule ratio and vascular density, introducing a ...

Prognostic significance of tumor microenvironment assessed by machine learning algorithm in surgically resected non‐small cell lung cancer

open access: yesCancer Reports, EarlyView., 2023
Abstract Background A methodology to assess the immune microenvironment (IME) of non‐small cell lung cancer (NSCLC) has not been established, and the prognostic impact of IME factors is not yet clear. Aims This study aimed to assess the IME factors and evaluate their prognostic values. Methods and Results We assessed CD8+ tumor‐infiltrating lymphocyte (

A Mathematical Model of Cellular Aggregation Predicts Patterns of Tau Accumulation in Neurodegenerative Disease

open access: yesAdvanced Science, EarlyView.
A minimal computational model of cellular aggregate formation in neurodegenerative disease, encompassing two competing processes: cell‐autonomous and cell‐to‐cell triggers of aggregation, is presented. Despite its simplicity, the model can reproduce the aggregate patterns observed in post‐mortem brain images from the primary tauopathy Progressive ...

Micro/Nanorobots for Combating Brain Disorders: Challenges, Advances, and Perspectives

open access: yesAdvanced Science, EarlyView.
Micro/nanorobots (MNRs) offer a transformative approach for precision therapy in brain disorders. By overcoming biological barriers and enabling controlled propulsion, targeted delivery, and real‐time imaging/tracking, MNRs pave the way toward effective, minimally invasive treatments. This review outlines the interplay between brain disease challenges,

Defect Engineering in Semiconductor Photocatalysts: Enhancing Photocatalytic Activity for Green Energy Production

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
By creating anion and cation vacancies, scientists fine‐tune semiconductor bandgaps and extend light absorption, boosting charge separation in photocatalysts. Surface defects enhance reactant adsorption and carrier transport, while controlled bulk defects curb recombination.

Central hyperthyroidism due to an ectopic TSH-secreting pituitary tumor: a case report and literature review

open access: yesFrontiers in Endocrinology
Ectopic thyroid-stimulating hormone (TSH)-secreting tumors are extremely rare, with only 15 reported cases in the literature. Herein, we described a 60-year-old female patient with thyrotoxicosis and elevated or unsuppressed levels of TSH. Family history
