For patients with high-risk cutaneous squamous cell carcinomas treated with margin-negative resection, there were no significant differences in poor outcomes between the surgery only group and the surgery with adjuvant radiotherapy group. Randomized controlled trials are necessary to define the benefit of adjuvant radiotherapy in this setting.

Several reports have demonstrated the role of neutrophils in cancer wherein the focus has been drawn on the elevated neutrophil count in blood or at tumor loci. However, their role in mediating systemic effects during cancer progression has not been deciphered so far. Therefore, it is worthwhile to explore whether and how neutrophils contribute to systemic deterioration in cancer. To discern their systemic role, we evaluated neutrophil count and function at different stages of tumor growth in Dalton's Lymphoma mice model. Notably, our results displayed a gradual increase in Ly6G+ neutrophils in peripheral blood and their infiltration in vital organs including liver, lungs, spleen, kidney, lymph nodes and peritoneum of tumor bearing host. We showed remarkable alterations in histoarchitecture and serum enzyme levels that aggravated with tumor progression. We next examined neutrophil function by assessing its granular cargoes including neutrophil elastase (NE), myeloperoxidase (MPO), and matrix metalloproteinases (MMP-8 and MMP-9). Interestingly, blood neutrophils of tumor bearing mice exhibited a marked change in morphology with gradual increase in NE and MPO expression with tumor growth. In addition, we observed upregulated expression of NE, MPO, MMP-8 and MMP-9 in the vital organs of tumor bearing host. Taken together, our results demonstrate heightened infiltration and function of neutrophils in vital organs of tumor bearing host which possibly account for gradual systemic deterioration during cancer progression. find more Our findings thus implicate neutrophils as a potential therapeutic target that may help to reduce the overall fatality rate of cancer.

Acyl-CoAcholesterol acyltransferase (ACAT) inhibitors have been considered as potential therapeutic agents to treat several diseases, including Alzheimer's disease, atherosclerosis, and cancer. While many ACAT inhibitors are readily available, methods to encapsulate them as nanoparticles have not been reported.

We report a simple method to encapsulate ACAT inhibitors, using the potent hydrophobic ACAT inhibitor F12511 as an example. By mixing DSPE-PEG

egg phosphatidylcholine (PC), and F12511 in ethanol, followed by drying, resuspension and sonication in buffer, we show that F12511 can be encapsulated as stealth liposomes at high concentration.

We successfully incorporated F12511 into nanoparticles and found that increasing PC in the nanoparticles markedly increased the amount of F12511 incorporated in stealth liposomes. The nanoparticles containing F12511 (Nanoparticle F) exhibit average size of approximately 200nm and are stable at 4ºC for at least 6 months. Nanoparticle F is very effective at inhibiting ACAT in human and mouse neuronal and microglial cell lines. Toxicity tests using mouse primary neuronal cells show that F12511 alone or Nanoparticle F added at concentrations from 2 to 10µM for 24-, 48-, and 72-hours produces minimal, if any, toxicity.

Unlike existing methods, the current method is simple, cost effective, and can be expanded to produce tagged liposomes to increase specificity of delivery. This also offers opportunity to embrace water soluble agent(s) within the aqueous compartment of the nanoparticles for potential combinatorial therapy.

This method shows promise for delivery of hydrophobic ACAT inhibitors at high concentration in vivo.

The temporal precision in neural spike train data is critically important for understanding functional mechanism in the nervous systems. However, the timing variability of spiking activity can be highly nonlinear in practical observations due to behavioral variability or unobserved/unobservable cognitive states.

In this study, we propose to adopt a powerful nonlinear method, referred to as the Fisher-Rao Registration (FRR), to remove such nonlinear phase variability in discrete neuronal spike trains. We also develop a smoothing procedure on the discrete spike train data in order to use the FRR framework.

We systematically compare the FRR with the state-of-the-art linear and nonlinear methods in terms of model efficiency and effectiveness.

We show that the FRR has superior performance and the advantages are well illustrated with simulation and real experimental data.

It is found the FRR framework provides more appropriate alignment performance to understand the temporal variability in neuronal spike trains.

Standardized registration and evaluation of adverse events (AEs) are essential to assess the safety of endoscopic procedures. We propose a novel classification system Adverse events in GastRointEstinal Endoscopy (AGREE), adapted from a widely accepted surgical tool.

The Clavien-Dindo classification for surgical AEs was adapted for endoscopy. To validate the novel classification, we assessed if the severity of AEs, as perceived by 10 endoscopists, 10 endoscopy nurses, and 10 patients, corresponded with the severity grading used in the AGREE classification in 10 pairwise comparisons. We additionally assessed the correlation between the AGREE classification and the American Society for Gastrointestinal Endoscopy (ASGE) classification. The acceptability of the AGREE classification was evaluated through an international questionnaire.

The perception of endoscopists, endoscopy nurses and patients corresponded with the severity grading of the AGREE classification in 80% of the cases (238/299). The AGREE classiementation of the AGREE classification may facilitate the evaluation of AEs across different endoscopists, disciplines, endoscopy services and regions. This standardization of AE reporting will support improved quality assurance in gastrointestinal endoscopy.

The measurement of the portosystemic pressure gradient (PSG) in patients with advanced liver disease is helpful to assess the severity of portal hypertension (PH) and predict adverse clinical outcomes. EUS-guided PSG (EUS-PSG) measurement is a novel tool to assess PSG in all patients with advanced liver disease. We sought to assess the safety, feasibility, and technical success of simultaneous EUS-PSG measurement and EUS-guided liver biopsy sampling using a single-center experience.

Patients with suspected liver disease or cirrhosis were enrolled prospectively from 2020 to 2021. EUS-PSG was measured by calculating the difference between the mean portal pressure and the mean hepatic vein pressure. PH was defined as PSG >5mm Hg and clinically significant PH as PSG≥10mm Hg. The primary outcomes were procedural technical success rate and correlation of EUS-PSG with fibrosis stage obtained from concurrent EUS-guided liver biopsy sampling and the correlation of EUS-PSG with patients' imaging, clinical, and lsis.

Little is known about how cyberbullying victimization may influence adolescent nonsuicidal self-injury (NSSI) and what conditions may buffer the detrimental effects of cyberbullying victimization. By integrating multiple theories, this study investigated emotion reactivity as an underlying mediator and mindfulness as a potential moderator to explain the link between cyberbullying victimization and NSSI among Chinese adolescents.

A total of 2,523 participants with an age range of 11 to 16 years old (Mage=13.22, SD=1.60, 48.4% girls) completed assessments.

After controlling SES, age, gender, traditional bullying victimization, and child maltreatment, latent moderated structural equation modeling revealed that emotion reactivity mediated the association between cyberbullying victimization and NSSI. In addition, dispositional mindfulness was found to buffer the relation between cyberbullying victimization and NSSI, but not the relation between cyberbullying victimization and emotion reactivity.

This study was cross-sectional in nature and relied exclusively upon self-report measures.

The findings provide researchers and practitioners with a deeper understanding of the relation between cyberbullying victimization and NSSI among adolescents and its underlying mechanism. Suggested intervention and prevention strategies include helping youth reduce emotion reactivity to break the cyberbullying victimization to NSSI cycle and to enhance youths' mindfulness to buffer against the ill effects of cyberbullying victimization.

In this cross-sectional study we recruited eleven subjects who had acquired blindness for between 1 and 36 years. For comparison, we studied four subjects with congenital blindness and seventeen age- and sex-matched sighted control subjects. We administered ten forced-choice questionnaires that probed one auditory category and four visual categories, namely object shape and size; object hue and lightness; word and letter shape; and the shape and features of famous faces. Subjects with congenital blindness performed worse than controls on all visual categories, but nevertheless performed better than chance on object structure or colour, suggesting that the answers to some questions about visual properties can be derived from haptic or non-visual semantic information. Subjects with acquired blindness performed similarly to controls on all categories except for facial memory, particularly for facial features. We conclude that there is a substantial "permastore" of visual semantic memory but that facial memories are less durable, perhaps indicating that they are either less over-learned or more dependent on visual representations than other forms of visual object information.
