Focal Adhesion Kinase (FAK) is a non-receptor tyrosine kinase pivotal in cellular signal transduction, regulating cell adhesion, migration, growth, and survival. However, the regulatory mechanisms of FAK during tumorigenesis and progression still need to be fully understood. Our previous study demonstrated that -GlcNAcylation regulates integrin-mediated cell adhesion.

Article Synopsis
  • Cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA) are crucial techniques in cardiac surgery that can lead to neuroinflammation through microglia activation in the central nervous system.
  • Research typically focuses on conditions like Alzheimer's and Parkinson's but pays less attention to how these processes occur during cardiac surgery.
  • This review highlights the need to explore microglia’s role in neuroinflammation related to CPB and DHCA, aiming to improve patient outcomes and guide future treatment strategies for cardiac surgery patients.

The South China Sea (SCS) is abundant with complex multiscale dynamic processes but their spatiotemporal variations, generation and evolution mechanisms, and mutual interactions remain inadequately understood due to the lack of long-term in situ observations. To explore oceanic multiscale dynamics in the SCS, the SCS Mooring Array (SCSMA) was began to be constructed since 2009. The SCSMA consists of ∼40 moorings and is the largest in situ ocean observing system in marginal seas worldwide.

It is unclear what part KLF7 plays in cervical cancer. In this study, immunohistochemical and bioinformatics analyses reveal that KLF7 expression is lower in normal cervical tissues than in cervical cancer tissues ( ≤0.05), and the high level of transcripts in cervical cancer tissues is negatively correlated with patients' overall and disease-free survival ( <0.

Background: Animal venom systems are considered as valuable model for investigating the molecular mechanisms underlying phenotypic evolution. Stonefish are the most venomous and dangerous fish because of severe human envenomation and occasionally fatalities, whereas the genomic background of their venom has not been fully explored compared with that in other venomous animals.

Results: In this study, we followed modern venomic pipelines to decode the Synanceia verrucosa venom components.

Dose-finding studies in oncology often include an up-and-down dose transition rule that assigns a dose to each cohort of patients based on accumulating data on dose-limiting toxicity (DLT) events. In making a dose transition decision, a key scientific question is whether the true DLT rate of the current dose exceeds the target DLT rate, and the statistical question is how to evaluate the statistical evidence in the available DLT data with respect to that scientific question. This article introduces generalized likelihood ratios (GLRs) that can be used to measure statistical evidence and support dose transition decisions.

Background: Observational studies have shown an association between Breast Cancer (BC) and Atrial Fibrillation (AF). However, due to confounding factors and reverse causality, the causal role between BC and AF remains unclear. In this study, bidirectional two-sample Mendelian randomization (MR) combined with meta-analysis was used to evaluate the causal association between BC and AF.

To investigate the impact of LncRNA 93358 on ischemia-reperfusion induced myocardial cell apoptosis and the underlying mechanism. After being subjected to hypoxia for 4 h, three models of hypoxia-reoxygenation (H/R) with reoxygenation times of 8, 16, and 24 h were established. The expression of LncRNA 93358 was detected by qPCR, and the most suitable conditions were selected for subsequent experiments.

Circularly polarized luminescence (CPL) is a fascinating luminescence phenomenon that has garnered significant research attention for chiroptical applications. In this study, we developed a highly sensitive chiroptical sensor by co-assembling G-quartet nanofibers and nonchiral nitrogen sulfur-doped carbon dots (N-S-CDs) for dual ion detection. The N-S-CDs were synthesized using the one-step microwave method, and a helical G-quartet-based nanofiber structure (g-fiber) was simultaneously formed from guanosine 5'-monophosphate (GMP) in the presence of Sr.

We report herein that three facile rearrangements of epoxy ketones can be employed for the efficient and practical synthesis of cephalotaxine, the parent member of the family of alkaloids. The Meinwald rearrangement of epoxy ketone (90%) was used for the preparation of the dense functional groups in the cyclopentane ring of cephalotaxine. A novel acid-catalyzed umpolung S2' rearrangement and the Wharton transposition reaction of epoxy ketones were also developed to synthesize the Mori intermediate via the key azaspiro allylic alcohols in a stereodivergent manner.

Background: The infiltration of macrophages into the lungs is a common characteristic of perivascular inflammation, contributing to vascular remodeling in pulmonary hypertension (PH). Peli1 (pellino E3 ubiquitin-protein ligase 1) plays a critical role in regulating the production of proinflammatory cytokines and the polarization of macrophages in various diseases. However, the role of Peli1 in PH remains to be investigated.

  • The NOTCH2NLC gene is linked to several neurological disorders through expansions of GGC repeats in its 5' untranslated region, which can lead to conditions like Parkinson's, dementia, and tremors.
  • The study used cellular models and CRISPR-Cas9 engineered mice with specific GGC repeat variations to investigate the effects of these repeats, particularly focusing on those with serine insertions.
  • Results showed that a specific intermediate repeat with serine insertion caused mitochondrial dysfunction and neurotoxicity, leading to PD-like symptoms in mice, including neuronal loss and behavioral impairments.

  • Electroacupuncture (EA) is effective and safe for knee osteoarthritis (KOA), but the best current intensity for pain relief hasn't been clear, prompting a comparison of high vs. low-intensity EA.
  • The meta-analysis included three randomized controlled trials with 472 participants and found that high-intensity EA significantly reduces pain compared to low-intensity EA, though both had similar functional improvement scores (WOMAC).
  • High-intensity EA also had a greater positive effect on emotional well-being than low-intensity EA, suggesting it may be the better choice for patients with KOA.

In particular, efficient oxidative demulsification is an effective method for oil-water separation. However, the inactivation of free radicals owing to the rapid release of transition metals is the main factor that reduces the effectiveness. In this study, a hydrophobic and lipophilic CP/SiO@Fe composite aerogel was prepared using carboxymethyl cellulose as substrate, polyvinyl alcohol as reinforcement, and SiO nanoparticles as hydrophobic modifier.

Curvilinear mask has received much attention in recent years due to its ability to obtain better image quality in advanced nodes. A common method for optimizing curvilinear mask in optical proximity correction (OPC) flow is moving control points on the edge directly (MCED-based OPC), but it requires storing mass data. This paper uses distance-versus-angle signature (DVAS), a one-dimensional function, to represent a two-dimensional boundary of mask.
