MicroRNAs in Colorectal Cancer Drug Resistance: Shooters become Targets

MicroRNAs (MiRNAs) are involved in the regulation of several biological processes such as development, differentiation, metabolism, apoptosis and proliferation. Recently, it has been shown that deregulated expression of miRNAs are present in different human cancers, suggesting a potential role in carcinogenesis [1,2]. Recent evidence suggests that miRNAs may represent potential new therapeutic approaches in patients with dru…

INFLAMMATORY BOWEL DISEASE AND COLORECTAL CANCER, NUTRACEUTICAL ASPECTS

2016

Nutraceuticals constitute a group of functional foods that provide added health benefits for various disorders including inflammatory bowel disease (IBD) and colorectal cancer (CCR). The main groups of nutraceuticals include probiotics, prebiotics omega 3 and antioxidants. Studies on nutraceutical showed that this type of food possessed similar properties to drugs but with the benefit of not having side effects. This mini review shows that probiotics and prebiotics, when administered simultaneously with traditional therapies, reduce IBD symptoms and reduce synthesis of enzymes probably involved in colorectal carcinogenesis. Moreover, Omega 3 reduces the synthesis of inflammation mediators a…

USEFULNESS OF CT COLONOGRAPHY IN PATIENTS WITH OCCLUSIVE COLORECTAL CANCER BEFORE METALLIC STENT PLACEMENT: A SINGLE ENTER EXPERIENCE

2015

Up to 15% of patients with colorectal cancer (CRC) present with large bowel obstruction. Currently, computed tomography colonography (CTC) is regarded as a promising technique for complete evaluation of the proximal colon and simultaneous assessment of extraluminal status. Aim of this retrospective, observational study is to evaluate the feasibility of using CTC for preoperative examination of the proximal colon before metallic stgent placement in patients with colon obstruction caused by CRC. Sixteen patients who demonstrated colonic obstruction caused by CRC, underwent CTC immediately after incomplete colonoscopy. Per-patient sensitivity of CTC for lesion 5 mm larger in diameter in the co…

Morphological distribution of μ chains and cd15 receptors in colorectal polyp and adenocarcinoma specimens

2013

BACKGROUND: We have recently investigated the localisation of immunoglobulin-producing cells (IPCs) in inflamed intestinal tissue samples from patients with inflammatory bowel disease (IBD), and identified two main patterns of B lymphocyte infiltration: one characterised by the moderate strong stromal localisation of small B1 cell-like IgM+/CD79+/CD20-/CD21-/CD23-/CD5 ± IPCs, and the other by the peri-glandular localisation of IPCs with irregular nuclei that had surface markers specific for a B cell subset (IgM and CD79), but quantitative differences in their λ and κ chains. The same patients were also tested for CD15+ receptors, which were localised on inflammatory cell surfaces or in the …

Missense and nonsense mutations in melanocortin 1 receptor (MC1R) gene of different goat breeds: association with red and black coat colour phenotype…

2009

Abstract Background Agouti and Extension loci control the relative amount of eumelanin and pheomelanin production in melanocytes that, in turn, affects pigmentation of skin and hair. The Extension locus encodes the melanocortin 1 receptor (MC1R) whose permanent activation, caused by functional mutations, results in black coat colour, whereas other inactivating mutations cause red coat colour in different mammals. Results The whole coding region of the MC1R gene was sequenced in goats of six different breeds showing different coat colours (Girgentana, white cream with usually small red spots in the face; Maltese, white with black cheeks and ears; Derivata di Siria, solid red; Murciano-Granad…

Energy balance in single exposure multispectral sensors

2013

International audience; Recent simulations of multispectral sensors are based on a simple Gaussian model, which includes filters transmittance and substrate absorption. In this paper we want to make the distinction between these two layers. We discuss the balance of energy by channel in multispectral solid state sensors and propose an updated simple Gaussian model to simulate multispectral sensors. Results are based on simulation of typical sensor configurations.

Accuracy of an Affordable Smartphone-Based Teledermoscopy System for Color Measurements in Canine Skin

2020

Quality smartphone cameras and affordable dermatoscopes have enabled teledermoscopy to become a popular medical and veterinary tool for analyzing skin lesions such as melanoma and erythema. However, smartphones acquire images in an unknown RGB color space, which prevents a standardized colorimetric skin analysis. In this work, we supplemented a typical veterinary teledermoscopy system with a conventional color calibration procedure, and we studied two mid-priced smartphones in evaluating native and erythematous canine skin color. In a laboratory setting with the ColorChecker, the teledermoscopy system reached CIELAB-based color differences &Delta
