A novel hybrid model for predicting tertiary lymphoid structures and targeted immunotherapy outcomes in hepatocellular carcinoma: a multicenter retrospective study.

Objective: To develop a novel hybrid model for preoperative prediction of tertiary lymphoid structures (TLSs) of hepatocellular carcinoma (HCC), and to identify patients who may benefit from postoperative targeted immunotherapy.

Methods: Retrospective data were gathered from 332 patients with HCC who underwent surgical resection and gadoxetate disodium (Gd-EOB-DTPA) enhanced MRI at two tertiary hospitals (training cohort, n = 205; internal validation cohort, n = 90; and external validation cohort, n = 37) between March 2020 and January 2023. Radiomic features were extracted from Gd-EOB-DTPA-enhanced MRI sequences.

Acute remote ischemic conditioning enhances (CD3+)- but not (FoxP3+)-T-cell invasion in the tumor center and increases IL 17 and TNF-alpha expression in a murine melanoma model.

Introduction: Hypoxia can drive tumor progression, suppress anti-tumor immunity, and reduce the effectiveness of radiotherapy and chemotherapy. This study aimed to assess the impact of remote ischemic conditioning (RIC) on tumor oxygenation (sO2) and the anti-tumor immune response.

Material And Methods: Fourteen B16-Ova tumor-bearing C57BL/6N mice received six 5-minute RIC cycles, while another fourteen underwent anesthesia only.

Tumor microenvironment: Nurturing cancer cells for immunoevasion and druggable vulnerabilities for cancer immunotherapy.

The tumor microenvironment (TME) is an intricate ecosystem where cancer cells thrive, encompassing a wide array of cellular and non-cellular components. The TME co-evolves with tumor progression in a spatially and temporally dynamic manner, which endows cancer cells with the adaptive capability of evading immune surveillance. To this end, diverse cancer-intrinsic mechanisms were exploited to dampen host immune system, such as upregulating immune checkpoints, impairing antigens presentation and competing for nutrients.

Design and evaluation of collagenase-loaded nanoparticles for mechanical intervention of orthotopic hepatocellular carcinoma in rat model.

Altered tissue mechanics is vital for cancer development and malignancy, whether targeting the mechanical microenvironment could retard the initiation and progression of tumor is less explored. In this study, an orthotopic hepatocellular carcinoma (HCC) rat model was constructed to reproduce the mechanical and pathophysiological microenvironment of HCC development. LpMSN@CLG, a liver-targeted (L) and pH-sensitive (p) mesoporous silica nanoparticle (MSN) encapsulated with collagenase type-I (CLG), and DOX-LpMSN@CLG, on the basis of LpMSN@CLG, encapsulated with CLG and doxorubicin (DOX), were prepared to reduce matrix stiffness by degrading collagen in liver and HCC tumor.

Interpretable multi-modal artificial intelligence model for predicting gastric cancer response to neoadjuvant chemotherapy.

Neoadjuvant chemotherapy assessment is imperative for prognostication and clinical management of locally advanced gastric cancer. We propose an incremental supervised contrastive learning model (iSCLM), an interpretable artificial intelligence framework integrating pretreatment CT scans and H&E-stained biopsy images, for improved decision-making regarding neoadjuvant chemotherapy. We have constructed and tested iSCLM using retrospective data from 2,387 patients across 10 medical centers and evaluated its discriminative ability in a prospective cohort (132 patients; ChiCTR2300068917).

Protease-activated receptor 2 deficient mice develop less angiotensin II induced left ventricular hypertrophy but more cardiac fibrosis.

Aims: Activation of Protease Activated Receptor 2 (PAR2) has been shown to be involved in regulation of injury-related processes including inflammation, fibrosis and hypertrophy. In this study we will investigate the role of PAR2 in cardiac injury in a mouse model of hypertension using continuous infusion with angiotensin II.

Methods: Hypertension was induced in 12 weeks old wildtype (wt, n = 8) and PAR2 deficient mice (n = 9) by continuous infusion with angiotensin II for 4 weeks using osmotic minipumps.

Extracellular vesicles from fifth-stage larval upregulate cholesterol biosynthesis and suppress NLRP2-associated inflammatory responses in mouse astrocytes.

is a zoonotic parasite that causes severe symptoms in humans, including eosinophilic meningitis and eosinophilic meningoencephalitis. Extracellular vesicles (EVs) derived from helminthes have been implicated in regulating host survival and immune response. However, the roles of EVs in modulating parasite pathogenesis and host immune response remain poorly understood.

High iASPP (PPP1R13L) expression is an independent predictor of adverse clinical outcome in acute myeloid leukemia (AML).

Apoptosis-stimulating proteins of p53 (ASPPs) are a family of proteins that modulate key tumor suppressor pathways via direct interaction with p53. Deregulation of these proteins promotes cancer development and impairs sensitivity to systemic (chemo)therapy and radiation. In this study, we describe that the inhibitor of ASPP (iASPP) is frequently highly expressed in acute myeloid leukemia (AML) and that overexpression correlates with a poor clinical outcome.

Darier disease: Current insights and challenges in pathogenesis and management.

Darier disease is a rare autosomal dominant genodermatosis caused by mutations in the ATP2A2 gene encoding for sarcoendoplasmic reticulum Ca ATPase isoform 2. The skin disease is characterized by a chronic relapsing course with recurrent reddish-brown keratotic papules and plaques located mainly in seborrhoeic areas. Due to chronic inflammation and epidermal barrier defects of the skin, patients often develop severe bacterial and viral superinfections.

Severe gastroparesis complicated by gastric perforation caused by lightchain amyloidosis.

AL-Amyloidosis is a rare systemic disease that can occur in patients with monoclonal gammopathy or multiple myeloma. As multiple organs may be affected by deposition of amyloid fibrils, the clinical presentation varies considerably, and the diagnostic process may be challenging.We report on a 59-year-old female who suffered from gastroesophageal reflux symptoms, nausea, epigastric pain, and meteorism over several years.

Synergistic antiviral potential of N-(2-hydroxy)propyl-3-trimethylammoniumchitosan-functionalized silver nanoparticles with oseltamivir against influenza A viruses.

This study introduced a novel antiviral approach by combining three substances with different antiviral mechanisms: N-(2-hydroxy)propyl-3-trimethylammoniumchitosan (HTC), silver nanoparticles (AgNPs), and oseltamivir. First, positively surface-charged AgNPs were prepared using an environmentally friendly method. The surfaces of these AgNPs were capped with cationic quaternary chitosan HTC.

Case report: Pulmonary Ewing sarcoma disguised as non-small cell lung cancer.

Ewing sarcoma is the second most common primary malignant bone cancer in children and adolescents. This rare type of cancer is characterized by its high malignancy and therefore high risk of metastases. Typically, Ewing sarcomas originate from bones.

Neuroanatomical location of lung cancer brain metastases in 234 patients with a focus on cancer subtyping and biomarkers.

Brain metastases are frequent in neuropathology practices; however, the literature on their distribution is frequently derived from imaging studies. This work examined metastases of lung cancer to the brain through the lens of pathology specimens. All brain surgical pathology cases accessioned from 2011-2020 were retrieved from a regional laboratory.

[The nomogram model and its value study of Gd-EOB-DTPA enhanced MRI for preoperative diagnosis of proliferative hepatocellular carcinoma].

To develop a nomogram model for preoperative diagnosis of proliferative hepatocellular carcinoma(HCC) based on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) enhanced magnetic resonance imaging (MRI), and to explore its clinical value. MRI and clinical pathological data of patients confirmed by pathology as proliferative HCC (178 cases) and non-proliferative HCC (378 cases) between September 2017 and November 2022 who underwent preoperative Gd-EOB-DTPA enhanced MRI scans were retrospectively collected. The MRI features and clinical pathological characteristics of proliferative and non-proliferative HCC were evaluated.

DNA methylation classifier to diagnose pancreatic ductal adenocarcinoma metastases from different anatomical sites.

Background: We have recently constructed a DNA methylation classifier that can discriminate between pancreatic ductal adenocarcinoma (PAAD) liver metastasis and intrahepatic cholangiocarcinoma (iCCA) with high accuracy (PAAD-iCCA-Classifier). PAAD is one of the leading causes of cancer of unknown primary and diagnosis is based on exclusion of other malignancies. Therefore, our focus was to investigate whether the PAAD-iCCA-Classifier can be used to diagnose PAAD metastases from other sites.

Micropapillary pattern in serous borderline ovarian tumor and the risk of extraovarian localization of low-grade serous carcinoma ('invasive implants'): A systematic review and meta-analysis.

In serous borderline ovarian tumor (SBOT), a micropapillary (MP) pattern has been considered analogous to intraepithelial low-grade serous carcinoma (LGSC). On this account, it is reasonable to hypothesize that MP-SBOT is more likely to be associated with extraovarian LGSC localizations (also referred to as 'invasive implants') compared to conventional SBOT. The aim of this study was to investigate the potential association between a MP pattern and invasive implants in SBOT.

Proton pump inhibitor attenuates acidic microenvironment to improve the therapeutic effects of MSLN-CAR-T cells on the brain metastasis.

The incidence of brain metastasis (BM) is gradually increasing, and the prognosis and therapeutic effect are poor. The emergence of immunotherapy has brought hope for the development of BM treatments. This study revealed that compared with primary cancers, BMs have a colder and more acidic tumor microenvironment (TME), resulting in reduced protein levels of mesothelin (MSLN), a promising target for chimeric antigen receptor-T (CAR-T) cell therapy for triple-negative breast cancer (TNBC) with BMs.

Dynamics of cell-free tumor DNA correlate with early MRI response during chemoradiotherapy in rectal cancer.

Background: In locally advanced rectal cancer, the prediction of tumor response during and after neoadjuvant treatment remains challenging. In terms of organ preservation, adaptive radiotherapy, and intensified (total) neoadjuvant therapies, biomarkers are desirable for patient stratification.

Methods: In 16 patients, weekly blood samples (n = 86) to detect cell-free tumor DNA (ctDNA) during long-course neoadjuvant chemoradiotherapy were analyzed.
