In 2001, Tang's team discovered a unique type of luminogens with substantial enhanced fluorescence upon aggregation and introduced the concept of "aggregation-induced emission (AIE)". Unlike conventional fluorescent materials, AIE luminogens (AIEgens) emit weak or no fluorescence in solution but become highly fluorescent in aggregated or solid states, due to a mechanism known as restriction of intramolecular motions (RIM). Initially considered a purely inorganic chemical phenomenon, AIE was later applied in biomedicine to improve the sensitivity of immunoassays.

Preserving Cervical Mobility: A Novel Robot-Assisted Approach for Atlas Fracture Fixation.

Am J Case Rep

January 2025

Department of Orthopedic Surgery, Sichuan Provincial People's Hospital, School of Medicine, University of Electronic Science and Technology of China, Chengdu, Sichuan, China.

BACKGROUND The management of unstable atlas fractures remains a subject of ongoing debate and controversy. The conservative surgical treatment commonly involves fusion, resulting in severe loss of cervical spine mobility, and a large incisions and extensive tissue dissection are required. We aim to introduce a novel concept and surgical approach for treating atlas fracture, one that involves minimizing trauma while maintaining mobility of the upper cervical spine without resorting to fusion.

Post-transplant cyclophosphamide (PTCy) and anti-thymocyte globulin (ATG) are mainstay prophylactic treatment options for graft-versus-host disease (GVHD), widely used in haploidentical stem cell transplantation. Due to a lack of prospective studies, a number of retrospective comparisons have yielded different conclusions as to which prophylaxis regimen is superior. We performed a meta-analysis of these studies to get more informed and comprehensive decisions from clinicians.

Aerobic exercise (AE) has been shown to offer significant benefits for Alzheimer's disease (AD), potentially influencing the gut microbiota. However, the impact of changes in intestinal flora in early Alzheimer's disease induced by aerobic exercise on metabolic pathways and metabolites is not well understood. In this study, 3-month-old APP/PS1 and C57BL/6 mice were divided into two groups each: a control group (ADC for APP/PS1 and WTC for C57BL/6) and an aerobic exercise group (ADE for APP/PS1 and WTE for C57BL/6).

Here, leveraging the superior carrying capacity and innate immunity-stimulating property of living bacteria, a nanomedicine-engineered bacterium, LR-S-CD/CpG@LNP, with optical responsiveness, immune-stimulating activity, and the ability to regulate microbiota metabolome is developed. Immunoadjuvant (CpG) and carbon dot (CD) co-loaded plant lipid nanoparticles (CD/CpG@LNPs) are constructed and conjugated to the surface of Limosilactobacillus reuteri (LR) via reactive oxygen species (ROS)-responsive linkers.

Article Synopsis
  • Photodynamic therapy (PDT) effectiveness is hampered by high levels of glutathione (GSH) in tumor cells, which helps maintain a stable environment, reducing treatment efficacy.
  • A new theranostic agent, Cy-Res, is developed to target mitochondria and selectively deplete GSH, leading to increased reactive oxygen species (ROS) and enhanced oxidative stress in tumor cells.
  • Cy-Res not only improves PDT outcomes for invasive melanoma by enabling effective cell death mechanisms but also offers significant potential for tumor imaging and treatment through its fluorescence enhancement capabilities.

In recent years, great progress has been made in haploidentical hematopoietic stem cell transplantation (haplo-HSCT) treatment for hematological malignant diseases because of the advent of novel conditioning regimens, optimized graft manipulation, improved graft-versus-host disease (GVHD) prophylaxis, and advances in supportive care. Recent studies have shown very favorable outcomes in severe aplastic anemia (SAA) patients, with comparable outcomes to those of patients receiving immune suppressive therapy (IST) and allogeneic HSCT from a matched sibling donor (MSD) or matched unrelated donor (MUD). However, most of the previous studies relied on single-center data analyses, and the conditioning regimen, GVHD prophylaxis and supportive care used were relatively singular.
