The pathogenesis of thoracic aortic aneurysm (TAA) in Marfan syndrome (MFS) is generally attributed to vascular smooth muscle cell (VSMC) pathologies. However, the role of immune cell-mediated inflammation remains elusive. Single-cell RNA sequencing identified a subset of CX3CR1+ macrophages mainly located in the intima in the aortic roots and ascending aortas of Fbn1C1041G/+ mice, further validated in MFS patients.

Background: We seek to study whether early initiation of renal replacement therapy (RRT) could reduce 90-day mortality and improve clinical outcomes in patients with acute kidney injury following acute type A aortic dissection.

Methods: This is a single-center, randomized, controlled trial that enrolled acute type A aortic dissection patients with severe post-operative acute kidney injury (Kidney Disease: Improving Global Outcomes (KDIGO) stage 2) and with plasma neutrophil gelatinase-associated lipocalin level > 150 ng/mL who did not have potentially life-threatening complications directly related to renal failure. Patients were randomized equally into two groups: the early RRT group received RRT within 6 hours of diagnosis of KDIGO stage 2; the standard treatment group was managed with RRT initiated within 8 hours of stage 3.

Raynaud's phenomenon is a vascular disorder, characterized by vasospasm-induced discoloration, numbness, and pain in the extremities. While pharmacological treatments and sympathectomy are commonly employed, many patients experience symptom recurrence, and effective therapies for refractory cases remain limited. This case study presents a 60-year-old male with severe Raynaud's symptoms, including fingertip necrosis, unresponsive to pharmacotherapy and endoscopic thoracic sympathectomy.

Article Synopsis
  • - Previous research indicates that males can perceive visual motion direction more quickly than females, prompting an investigation into whether the middle temporal visual complex (MT+) is responsible for these differences in perception duration.
  • - Using ultra-high field MRI, the study involved 95 participants to assess sex-related variations in brain structure and activity in the MT+ region, revealing that males have larger gray matter volume and enhanced spontaneous activity in the left MT+.
  • - The results highlight significant sex differences in brain structure and function, specifically in the MT+ area, which are associated with motion perception abilities, suggesting that these neural characteristics may contribute to the different temporal thresholds for motion discrimination between genders.

Handwriting Brain-Computer Interfaces (BCIs) provides a promising communication avenue for individuals with paralysis. While English-based handwriting BCIs have achieved rapid typewriting with 26 lowercase letters (mostly containing one stroke each), it is difficult to extend to complex characters, especially those with multiple strokes and large character sets. The Chinese characters, including over 3500 commonly used characters with 10.

  • Understanding how the motor cortex adapts during tasks that involve both sides of the body is key to furthering our grasp of how the brain learns and changes (neural plasticity).
  • Researchers used advanced imaging techniques to study specific neurons in mice while they performed a left-right lever-press task, revealing that these neurons behave differently based on whether the movement is on the same side or the opposite side.
  • The study found that these neurons not only adjust their activity patterns over time but also highlight the brain’s flexible reorganization during motor learning, which could be important for developing better rehabilitation strategies for motor skills.

  • Coronary artery involvement (CAI) is a notable yet not uncommon outcome of Takayasu arteritis (TAK), and this study aimed to explore the role of Granzyme B (GzmB) in patients with TAK and CAI.
  • The research included 105 TAK patients and 58 healthy controls, finding significant differences in various health metrics and an increased presence of certain immune cell types (CD3+CD8+ and CD3+CD4+) among TAK patients with CAI.
  • The study concluded that a higher ratio of CD3+CD8+GzmB+ cells in lymphocytes could serve as an independent risk factor for CAI and major adverse cardiovascular events (MACE), suggesting that targeting

Objective: This study aimed to explore the Liquid-liquid phase separation (LLPS)-related genes associated with the prognosis of bladder cancer (BCa) and assess the potential application of LLPS-related prognostic signature for predicting prognosis in BCa patients.

Methods: Clinical information and transcriptome data of BCa patients were extracted from the Cancer Genome Atlas-BLCA (TCGA-BLCA) database and the GSE13507 database. Furthermore, 108 BCa patients who received treatment at our institution were subjected to a retrospective analysis.

Objective: Speech brain-computer interfaces (speech BCIs), which convert brain signals into spoken words or sentences, have demonstrated great potential for high-performance BCI communication. Phonemes are the basic pronunciation units. For monosyllabic languages such as Chinese Mandarin, where a word usually contains less than three phonemes, accurate decoding of phonemes plays a vital role.

Aortic dissection (AD), caused by tearing of the intima and avulsion of the aortic media, is a severe threat to patient life and organ function. Iron is closely related to dissection formation and organ injury, but the mechanism of iron ion transport disorder in endothelial cells (ECs) remains unclear. We identified the characteristic EC of dissection with iron overload by single-cell RNA sequencing data.

The blood-brain barrier (BBB) is a selectively semi-permeable layer, crucial in shielding the brain from external pathogens and toxic substances while maintaining ionic homeostasis and sufficient nutrient supply. However, it poses a significant challenge for drugs to penetrate the BBB in order to effectively target brain tumors. Magnetic resonance-guided laser interstitial thermal therapy (MRg-LITT) is a minimally invasive technique that employs thermal energy to cauterize intracranial lesions with the potential to temporarily disrupt the BBB.

  • The study investigated the safety of high-moderate and low-moderate systemic hypothermia during circulatory arrest in patients with acute DeBakey I aortic dissection, focusing on spinal cord protection.
  • Over 1,700 patients were analyzed, showing that those in the nonmalperfusion subgroup experienced lower in-hospital mortality and kidney injury rates with high-moderate hypothermia compared to low-moderate hypothermia.
  • In contrast, patients with preoperative malperfusion had a higher risk of developing paraplegia with high-moderate hypothermia, suggesting that low-moderate hypothermia may be safer for this subgroup.

The primate amygdala serves to evaluate emotional content of sensory inputs and modulate emotional and social behaviors; it modulates cognitive, multisensory and autonomic circuits predominantly via the basal (BA), lateral (LA), and central (CeA) nuclei, respectively. Based on recent electrophysiological evidence suggesting mesoscale (millimeters-scale) nature of intra-amygdala functional organization, we have investigated the connectivity of these nuclei using Infrared Neural Stimulation of single mesoscale sites coupled with mapping in ultrahigh field 7T functional Magnetic Resonance Imaging (INS-fMRI). Stimulation of multiple sites within amygdala of single individuals evoked 'mesoscale functional connectivity maps', allowing comparison of BA, LA and CeA connected brainwide networks.
