Article Synopsis
  • Depression is linked to cognitive impairment and increases the risk of developing dementia, but the exact interaction between these factors has not been extensively studied.
  • In a study involving over 64,000 participants, those with either depressive symptoms, cognitive impairment, or both showed higher risks of subsequent dementia compared to those with neither condition.
  • Although having both depression and cognitive impairment posed a greater risk for dementia than having either condition alone, the study found no significant synergistic effects between depression and cognitive impairment on dementia risk.

Background: Major depressive disorder (MDD) is associated with deficits in cognitive function, thought to be related to underlying decreased hedonic experiences. Further research is needed to fully elucidate the role of functional brain activity in this relationship. In this study, we investigated the neurofunctional correlate of the interplay between cognitive function and hedonic experiences in medication-free MDD using functional near-infrared spectroscopy (fNIRS).

Article Synopsis
  • The study investigates how white matter hyperintensity (WMH) burden relates to cerebral edema (CED) and patient outcomes after endovascular thrombectomy (EVT) in stroke patients.* -
  • In a retrospective analysis of 344 patients, findings show that while WMH burden did not significantly affect the entire population, it was linked to increased risk of malignant cerebral edema and worse outcomes in patients without parenchymal hemorrhage.* -
  • The research indicates that CED partially mediates the relationship between WMH burden and poor functional outcomes at three months post-EVT.*

Article Synopsis
  • Childhood trauma significantly contributes to emotional distress, particularly anxiety and depression, among college students.
  • This study analyzed data from 2307 Chinese college students and found that a strong sense of coherence (SOC) can lessen the negative impact of childhood trauma on emotional distress.
  • Female students generally had higher SOC and lower anxiety/depression rates, despite experiencing more childhood trauma, indicating that SOC plays a crucial role in coping with these experiences.

Abnormally localized nucleic acids (NAs) are considered as pathogen associated molecular patterns (PAMPs) in innate immunity. They are recognized by NAs-specific pattern recognition receptors (PRRs), leading to the activation of associated signaling pathways and subsequent production of type I interferons (IFNs) and pro-inflammatory cytokines, which further trigger the adaptive immunity. Notably, NAs-mediated innate immune activation is highly dependent on the conformation changes, especially the aggregation of PRRs.

Detection of Mn in living cells is important in understanding the roles of Mn in cellular processes and investigating its potential implications in various diseases and disorders. Toward this goal, we have previously selected a Mn-specific 11-5 DNAzyme through an in vitro selection method and converted it into a fluorescence sensor for intracellular Mn sensing. Despite the progress, the nucleotides responsible for the activity are unclear, and the performance of the DNAzyme needs to be improved in order for more effective applications in biological systems.

Metal ions such as iron, zinc, copper, manganese, and calcium are essential for normal cellular processes, including DNA synthesis, enzyme activity, cellular signaling, and oxidative stress regulation. When the balance of metal homeostasis is disrupted, it can lead to various pathological conditions, including cancer. Thus, understanding the role of metal homeostasis in cancer has led to the development of anti-tumor strategies that specifically target the metal imbalance.

DNAzyme-based fluorescent probes for imaging metal ions in living cells have received much attention recently. However, employing in situ metal ions imaging within subcellular organelles, such as nucleus, remains a significant challenge. We developed a three-stranded DNAzyme probe (TSDP) that contained a 20-base-pair (20-bp) recognition site of a CRISPR/Cas9, which blocks the DNAzyme activity.

Antigen-presenting cells (APCs) play a crucial role in the anti-tumor immunity as they are responsible for capturing, processing, and presenting tumor antigens to T cells. However, their activation is often limited by the absence of adjuvants and the suppressive effects of immune checkpoints, such as CD47-SIRPα. Herein, we present a nanoadjuvant that is self-assembled from long RNA building blocks generated through rolling circle transcription (RCT) reaction and further modified with cationic liposomes.

Article Synopsis
  • A systematic review and meta-analysis were conducted to determine the impact of white matter hyperintensity (WMH) on clinical outcomes in acute ischemic stroke (AIS) patients after mechanical thrombectomy (MT).
  • The analysis included 15 studies with a total of 3,456 patients and found that moderate/severe WMH increased the likelihood of unfavorable functional outcomes, higher mortality, and futile recanalization compared to patients with none/mild WMH.
  • Despite these findings, the study noted no significant differences in successful recanalization or hemorrhagic events between the two groups, and a key limitation was the lack of adjustment for important baseline factors.

Manganese is an essential trace element in the human body that acts as a cofactor in many enzymes and metabolisms. It is important to develop methods to detect Mn in living cells. While fluorescent sensors have been very effective in detecting other metal ions, Mn-specific fluorescent sensors are rarely reported due to nonspecific fluorescence quenching by the paramagnetism of Mn and poor selectivity against other metal ions such as Ca and Mg.

A novel fluorescent sensor BTAE-PA containing two tetrarylethylene (TAE) units linked through pyrimidine-2-amine was prepared, and its optical properties were systematically studied. BTAE-PA exhibited a typical aggregation-induced emission enhancement behavior, and its fluorescent properties could be efficiently modulated by acid/base and metal ions in THF. The protonated effect could induce significant acidichromism and 'turn-on' near-infrared emission with a large Stokes shift (Δ = 225 nm).
