Multiplex analysis of colorectal cancer tissue describes the composition, cell biology and spatial effects of cell-in-cell events and identifies a T cell-dependent prognostic signature.

Cell-in-cell (CIC) structures, in which one cell is entirely engulfed by another, have been associated with poor outcomes in cancers. However, the mechanisms underlying this association remain poorly understood. We performed multiplex imaging of 56 cell identity, cell 'state' and cancer 'hallmark' proteins to characterise CICs, map their spatial interactions, and assess clinical associations across 444 tumour cores from 148 colorectal cancer patients, which contained over one million spatially resolved cells.

High-Resolution Spatial Proteomics Characterises Colorectal Cancer Consensus Molecular Subtypes.

Background: Identification of the consensus molecular subtypes (CMS) opened significant potential for understanding the tumor biology and intertumoral heterogeneity of colorectal cancer (CRC). However, molecular subtyping in CRC traditionally relies on bulk transcriptomics, therefore, lacks spatial and single-cell level aspect.

Methods: We constructed tissue microarrays using tumor cores from 222 CRC patients.

The recombinant anti-MET/EpCAM bispecific antibody fragment: a promising novel therapeutic approach for breast cancer treatment.

Our study aims to target Met and EpCAM to inhibit angiogenesis in breast cancer, particularly triple-negative breast cancer (TNBC). We have developed a new bispecific antibody that targets both MET and EpCAM, which are commonly overexpressed in tumor cells. This antibody aims to reduce tumor cell proliferation and spread.

Integrated multiplex analysis of cell death regulators in stage II colorectal cancer suggests patients with 'persister' cell profiles fail to benefit from adjuvant chemotherapy.

Objective: Inducing tumour cell apoptosis is a primary objective of chemotherapy but, to date, there are no validated biomarkers of apoptosis sensitivity or resistance. Our objective was to image multiple apoptosis pathway proteins at single cell level and determine multi-protein associations with recurrence risk and chemotherapy response in patients with stage II colorectal cancer (CRC).

Methods And Analysis: Multiplexed imaging of 16 proteins in the intrinsic and extrinsic apoptosis pathways at single cell resolution on resected tissue from 194 patients with stage II CRC who either received adjuvant chemotherapy (n108) or were treated with surgery only (n=86).

Emerging immunologic approaches as cancer anti-angiogenic therapies.

Targeting tumor angiogenesis, the formation of new blood vessels supporting cancer growth and spread, has been an intense focus for therapy development. However, benefits from anti-angiogenic drugs like bevacizumab have been limited by resistance stemming from activation of compensatory pathways. Recent immunotherapy advances have sparked interest in novel immunologic approaches that can induce more durable vascular pruning and overcome limitations of existing angiogenesis inhibitors.

Spatial effects of infiltrating T cells on neighbouring cancer cells and prognosis in stage III CRC patients.

Colorectal cancer (CRC) is one of the most frequently occurring cancers, but prognostic biomarkers identifying patients at risk of recurrence are still lacking. In this study, we aimed to investigate in more detail the spatial relationship between intratumoural T cells, cancer cells, and cancer cell hallmarks as prognostic biomarkers in stage III colorectal cancer patients. We conducted multiplexed imaging of 56 protein markers at single-cell resolution on resected fixed tissue from stage III CRC patients who received adjuvant 5-fluorouracil (5FU)-based chemotherapy.

Emergent method for management of splenic artery aneurysms rupture: A case report.

Introduction And Importance: Although endovascular therapy is becoming more used for the treatment of splenic artery aneurysms (SAAs) instead of open surgery, there is limited information available on the emergent hybrid approach, selectively. We present our experience of hybrid therapy using an emergent endovascular balloon for inflow control and open resection.

Case Presentation: A 34-year-old woman was brought to the emergency room after it was reported that she had a pseudoaneurysm in her splenic artery at a different medical facility.

Spatial Effects of Infiltrating T cells on Neighbouring Cancer Cells and Prognosis in Stage III CRC patients.

Colorectal cancer (CRC) is one of the most frequently occurring cancers, but prognostic biomarkers identifying patients at risk of recurrence are still lacking. In this study, we aimed to investigate in more detail the spatial relationship between intratumoural T cells, cancer cells, and cancer cell hallmarks, as prognostic biomarkers in stage III colorectal cancer patients. We conducted multiplexed imaging of 56 protein markers at single cell resolution on resected fixed tissue from stage III CRC patients who received adjuvant 5-fluorouracil-based chemotherapy.

A Comparison of the Characteristics of Cytokine Storm between Lichen Planus and Oral Squamous Cell Carcinoma.

Introduction: Lichen planus (LP) is a relatively common chronic mucocutaneous disease that affects the skin and mucous membranes, including oral mucosa. The etiology of the disease is unknown. Some evidence suggests that the immune system and inflammation may play a role in the formation and progression of lichen planus.

Superparamagnetic Iron Oxide Nanoparticles Induce Apoptosis in HT-29 Cells by Stimulating Oxidative Stress and Damaging DNA.

Nanoparticles have garnered considerable scientific attention in recent years due to their diagnostic and therapeutic applications in cancer. The purpose of this study was to determine the effect of superparamagnetic iron oxide nanoparticles (FeO MNPs) on the induction of apoptosis in human colorectal adenocarcinoma cell line (HT-29) cells. The purpose of this study was to elucidate the mechanisms of apoptosis induced by FeO MNPs following MTT assay and to determine the optimal dose of 2.

The Effect of on Hepatic Enzymes Activity and Apoptosis-Related Gene Expression in Streptozotocin-Induced Diabetic Rats.

Many diseases, including diabetes, are involved in the development of liver disorders through changes in the expression of genes such as apoptosis-related genes. In the present study, the effect of (. ) on hepatic enzyme activity and apoptosis-related gene expression in streptozotocin (STZ)-induced diabetic rats was examined.

Apoptosis Induced by Ziziphora tenuior Essential Oil in Human Colorectal Cancer Cells.

Ziziphora (Cacotti in Persian) belongs to the Lamiaceae family (mint group) and is vastly found in Iran and Asia. This traditional medicinal plant is normally used as analgesic and for treatment of particular gastrointestinal diseases. Since colorectal cancer is one of the most common causes of death in the world and the second leading cause of cancer death among adults, there is a pressing need to inhibit this malignancy by using methods with minimal side effects.

Age dependency of the diabetes effects on the iris recognition systems performance evaluation results.

In this paper, we attempt to answer the questions whether iris recognition task under the influence of diabetes would be more difficult and whether the effects of diabetes and individuals' age are uncorrelated. We hypothesized that the health condition of volunteers plays an important role in the performance of the iris recognition system. To confirm the obtained results, we reported the distribution of usable area in each subgroup to have a more comprehensive analysis of diabetes effects.

Iris recognition under the influence of diabetes.

In this study, iris recognition under the influence of diabetes was investigated. A new database containing 1318 pictures from 343 irides - 546 images from 162 healthy irides (62% female users, 38% male users, 21% <20 years old, 61% (20) < 40 years old, 12% (40) <60 years old and 6% more than 60 years old) and 772 iris images from 181 diabetic eyes but with a clearly visible iris pattern (80% female users, 20% male users, 1% <20 years old, 17.5% (20) <40 years old, 46.
