To optimize the efficacy of analgesia for patients receiving laparoscopic inguinal hernia repair, peri-operative pain neuroscience education (PNE) as a pain-specific cognitive therapy was incorporated into multi-modal analgesia. A randomized controlled trial was conducted to compare conventional analgesia (group CA) and the addition of pain neuroscience education into it (group PNE) in patients receiving laparoscopic inguinal hernia repair. Characteristics of peri-operative pain was evaluated with Douleur Neuropathique 4 questionnaire (DN-4), central sensitization inventory (CSI), pain catastrophizing scale (PCS) post-operatively and pressure pain threshold.

In yeast and mammals, the EXO70 subunit of the exocyst complex plays a key role in mediating the tethering of exocytic vesicles to the plasma membrane (PM). In plants, however, the role of EXO70 in regulating vesicle tethering during exocytosis remains unclear. In land plants, EXO70 has undergone significant evolutionary expansion, resulting in multiple EXO70 paralogues that may allow the exocyst to form various isoforms with specific functions.

The proliferation of tumors is not merely self-regulated by the cancer cells but is also intrinsically connected to the tumor microenvironment (TME). Within this complex TME, cancer-associated fibroblasts (CAFs) are pivotal in the modulation of tumor onset and progression. Rich signaling interactions exist between CAFs and tumor cells, which are crucial for tumor regulation.

Background: In the traditional computed tomography (CT) simulation process, patients need to undergo CT scans before and after injection of iodine-based contrast agent, resulting in a cumbersome workflow and additional imaging dose. Contrast-enhanced spectral CT can synthesize true contrast-enhanced (TCE) images and virtual noncontrast (VNC) images in a single scan without geometric misalignment. To improve work efficiency and reduce patients' imaging dose, we studied the feasibility of using VNC images for radiotherapy treatment planning, with true noncontrast (TNC) images as references and explored its dosimetric advantages compared to using TCE images.

Straightforward genotyping can provide timely diagnostic information for diseases prevention and treatment. Taking advantages of speediness and convenience, although numerous genotyping strategies combined loop-mediated isothermal amplification (LAMP) and lateral flow have been reported to satisfy the demand of point-of-care test, the false positive result caused by aerosol and primer dimer as an innate conflict seriously limits their practical application. In this study, both aerosol and primer dimer as extrinsic and intrinsic inducements respectively are first broken through at one stroke based on an integrated immunochromatographic biosensor.

Article Synopsis
  • Hepatic fibrosis is a serious disease with high rates of illness and death, but its mechanisms are not well understood, making treatment development difficult.
  • The study found that lower levels of MKP5 in liver tissues from mice with fibrosis lead to more severe disease and suggested that MKP5 operates by blocking harmful cell activation and apoptosis through a specific cellular pathway.
  • Creating nanoparticles that deliver MKP5 effectively reduced liver inflammation and fibrosis in mice, indicating that targeted therapy using MKP5 might be a new way to treat this condition.

Some neural representations gradually change across multiple timescales. Here we argue that modeling this "drift" could help explain the spacing effect (the long-term benefit of distributed learning), whereby differences between stored and current temporal context activity patterns produce greater error-driven learning. We trained a neurobiologically realistic model of the entorhinal cortex and hippocampus to learn paired associates alongside temporal context vectors that drifted between learning episodes and/or before final retention intervals.
