Comparison of Claudin 18.2 expression in primary tumors and lymph node metastases in Japanese patients with gastric adenocarcinoma.
2019
CLDN18.2 expression is highly prevalent in Japanese patients with gastric cancer, making it a targetable alteration, and supporting development of zolbetuximab as a therapeutic agent for this patient population.
Experimental evolution of an oncolytic vesicular stomatitis virus with increased selectivity for p53-deficient cells
2014
Experimental evolution has been used for various biotechnological applications including protein and microbial cell engineering, but less commonly in the field of oncolytic virotherapy. Here, we sought to adapt a rapidly evolving RNA virus to cells deficient for the tumor suppressor gene p53, a hallmark of cancer cells. To achieve this goal, we established four independent evolution lines of the vesicular stomatitis virus (VSV) in p53-knockout mouse embryonic fibroblasts (p53-/- MEFs) under conditions favoring the action of natural selection. We found that some evolved viruses showed increased fitness and cytotoxicity in p53-/- cells but not in isogenic p53+/+ cells, indicating gene-specifi…

Capsaicin Intake and Oral Carcinogenesis: a Systematic Review
2021
Background Chili is the most heavily and frequently consumed spice, either as a flavouring or colouring agent, and it is also a major source of pro-vitamin A, vitamin E and C. The main capsinoidcapsaicinoid found in chili peppers is capsaicin. It has been demonstrated that capsaicin acts as a cancer-suppressing agent through its antioxidant and anti-inflammatory effects, by blocking several signal transduction pathways. Oral squamous cell carcinoma is one of the most prevalent cancer worldwide. It is noteworthy that in countries where populations of diverse ethnic groups co-exist, differences have been observed in terms of incidence of oral cancer. The variances in their diet could explain,…
Rare cardiomyopathies: Diagnostic features
2013
Cardiomyopathies (CM) are an important and heterogeneous group of diseases affecting the myocardium. They can induce mechanical and/or electrical disorders and are due to a variety of causes, they frequently are genetic. However, since their high number and their clinical complexity, the identification is still a challenge. Echocardiography is a very useful tool in the assessment of CM. In this review we aim to define the typical clinical features and to discuss the main diagnostic tool, above all echocardiography that can help physicians in the correct assessment of CM.
Coronary Artery Disease in South Asian Patients: Cardiovascular Risk Factors, Pathogenesis and Treatments.
2022
In the last decades a significant increase of the migratory phenomenon from South Asian countries to the Western World has occurred for social, economic and geopolitical reasons. The aim of this review is to describe cardiovascular risk factors, pathogenesis and treatments of coronary artery disease in South Asian patients. It is well established that South Asian populations have a higher prevalence of coronary artery disease and premature onset of myocardial infarction episodes than other populations. This higher predisposition might be caused by genetic factors, common in both South Asian patients residing in their birth country and in those residing abroad, but it may also be due to the …
Kinking, coiling, and tortuosity of extracranial internal carotid artery: is it the effect of a metaplasia?
2006
INTRODUCTION: Morphological anomalies of the extracranial internal carotid artery (ICA) cause symptomatic cerebrovascular insufficiency in 4-16% of the cases. The aim of the present study is to evaluate macroscopic and microscopic features of a group of extracranial ICA anomalies, specifically kinking, coiling, and tortuosity, eventually affecting the surgical approach. MATERIALS AND METHODS: From January 2003 to December 2005, 10 out of 169 (6%) revascularized patients (pts) were operated upon because of an ICA anomaly. They were all but two symptomatics. Seven pts were treated by ICA transection and end-to-side reimplantation of the ICA at the level of the carotid bulb; three pts were tre…
Meta-analysis of the correlation between serum uric acid level and carotid intima-media thickness
2021
Objective Recently, increasing epidemiological evidence has shown that there is a correlation between serum uric acid level (SUA) and carotid intima-media thickness (CIMT). This paper explored the relationship between them through meta-analysis. Methods PubMed, Cochrane Library, EMBASE, Web of Science and Google Scholar were searched to obtain literature. The keywords used to retrieve the literature were carotid intima thickness, intima-media thickness, carotid atherosclerosis, carotid stenosis, carotid artery, uric acid, blood uric acid, and hyperuricaemia. The retrieval time was from the establishment of the database through July 2020. Stata15.0 and RevMan5.3 software were used for stati…
External stenting with a new polyester mesh reduces neointimal hyperplasia of vein grafts in a sheep model.
2007
Objective External stents placed around vein grafts have demonstrated effectiveness in reducing neointimal hyperplasia by preventing distension of the thin-walled vein grafts when exposed to arterial pressure. However, the ideal stent material has yet to be defined. The following study investigates the short- and long-term effects of an innovative polyester mesh stent designed with optimized adaptation of circumferential compliance. Methods Following in vitro definition of the ideal macro-porous polyester stent material, a total of 12 sheep underwent implantation of bilateral carotid artery vein graft bypasses. In six sheep, the short-term outcome (four weeks of implantation) was investigat…
Chondrodysplasia punctata — Rhizomelic form
1976
Pathologic, ultrastructural and radiologic studies are described on 3 infants with the rhizomelic form of chondrodysplasia punctata. Radiologic criteria in the young infant include radiolucent coronal clefts dividing all or most of the thoracic and lumbar vertebral bodies, short humeri with flared metaphyses and punctate calcifications commonly present adjacent to the ossified ischial and pubic bones and less commonly in other locations. In late infancy and childhood the radiologic criteria include demineralization in all bones with slow maturation, flat vertebral bodies, short humeri and femora, metaphyseal flaring, especially in the distal humerus, proximal femur and proximal tibia, immat…
