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,…
Carcinoma epidermoide cutáneo: relación con los trastornos respiratorios del sueño y definición de la variante alto riesgo
2015
Introducción: Recientes publicaciones han mostrado que la hipoxia intermitente similar a la que encontramos en el síndrome de apnea e hipopnea del sueño (SAHS) parece estar implicada en el desarrollo, progresión y crecimiento de tumores en modelos animales, a través de la sobreproducción de factores de crecimiento (entre ellos el factor de crecimiento vascular endotelial o VEGF) y la interacción con la vía supresora del gen p53. EL carcinoma epidermoide cutáneo (CEC) es un tumor procedente de los queratinocitos del estrato espinoso de la epidermis, muy prevalente en la población general y cuya incidencia está en aumento. Su lesión precursora más frecuente es la queratosis actínica. Existe u…
Human HepG2 and rat Fao hepatic-derived cell lines show different responses to ciprofibrate, a peroxisome proliferator: analysis by flow cytometry.
1996
Abstract Peroxisome proliferators, and especially hypolipidemic drugs such as ciprofibrate, are known to be hepatocarcinogens in rodents, but their effect in humans is controversial. In an attempt to investigate the effects of ciprofibrate at a cellular level, the analysis of individual whole cells was performed by flow cytometry on samples from two hepatic-derived cell lines: the rat Fao cell line and the human HepG2 cell line. The increase of light scatter signals in rat Fao cells treated for 3 days with ciprofibrate at 250 μMwas related to modifications of intrinsic cellular parameters, such as size and cytoplasmic granularity. Conversely, no variations appeared in human HepG2-treated ce…
Stimulation of peroxisomal palmitoyl-CoA oxidase activity by ciprofibrate in hepatic cell lines: comparative studies in Fao, MH1C1 and HepG2 cells.
1993
The response of two rat cell lines, Fao and MH1C1, and one human cell line, HepG2, to the peroxisome proliferator ciprofibrate, was studied. Using a fluorometric assay for palmitoyl-CoA oxidase, the dose- and time-dependent increase of this enzymatic activity was determined. From the lowest concentration (100 microM) stimulation is evident in the two rat cell lines. In the Fao line, the activity was stimulated reaching a seven-fold increase over the control level at 250 microM after 72 h of treatment. In the MH1C1 line, the maximum stimulation, four- to five-fold, was obtained at 250 and 500 microM after 72 h. In the HepG2 cell line, activity increased two-fold at 250 microM after 72 h reac…
Physical activity and risk of atrial fibrillation in the general population : meta-analysis of 23 cohort studies involving about 2 million participan…
2021
Regular physical activity is well established to be associated with reduced risk of cardiovascular disease outcomes. Whether physical activity is associated with the future risk of atrial fibrillation (AF) remains a controversy. Using a systematic review and meta-analysis of published observational cohort studies in general populations with at least one-year of follow-up, we aimed to evaluate the association between regular physical activity and the risk of AF. Relevant studies were sought from inception until October 2020 in MEDLINE, Embase, Web of Science, and manual search of relevant articles. Extracted relative risks (RRs) with 95% confidence intervals (CIs) for the maximum versus the …
Abstract 13812: Pulmonary Function Predicts Cardiac Function, Structure & Clinical Outcome in Chronic Heart Failure: Results From the Myovasc Stu…
2020
Introduction: A growing body of evidence suggests a relevance of pulmonary function in the pathophysiology of heart failure (HF). Comprehensive data on the role of forced expiratory volume in 1 second (FEV1) in the development & progression of HF is limited. Hypothesis: Given this background, we hypothesized, that (FEV1) is associated with deteriorated left ventricular (LV) functional as well as structural status, & predicts specific clinical outcome in HF. Methods: Data from the MyoVasc Study (n=3,289) were analysed. Comprehensive clinical phenotyping including body plethysmography for the evaluation of FEV1 & standardized echocardiography were performed during a five-hour inv…
Nutraceuticals and Cardiovascular Disease
2021
Cardiovascular disease (CVD) remains the primary cause of mortality worldwide, taking an estimated 17.9 million lives each year. Among several cardiometabolic risk factors, dyslipidemia, and especially high low-density lipoprotein cholesterol (LDL-C) levels, are associated with the development and progression of atherosclerosis and its clinical sequelae. Recent studies have shown promising results for nutraceutical compounds on various CVD risk factors and complications. In addition to looking at individual nutrients or foods, dietary pattern have also emerged as a complementary approach to examine the relationship between the overall diet and the risk for CVD. The Mediterranean Diet (MedDi…
Current and emerging drugs for the treatment of atherosclerosis: the evidence to date
2022
Introduction: Atherosclerosis can be considered a chronic inflammatory process that stands out as a dominant cause of cardiovascular disease (CVD). Since blood lipids are the leading risk factor for atherosclerosis development, lowering low-density lipoprotein cholesterol (LDL-C) and other apolipoprotein B-containing lipoproteins reduces the risk of future cardiovascular events. However, there has been significant progress in developing lipid-lowering drugs for aggressive management of dyslipidemia, the rates of CVD events remain unacceptably high, so there is great need to identify novel therapeutic pathways targeting the atherosclerosis process.Areas covered: We discussed the current guid…
Relationships between diuretic related hyperuricemia and cardiovascular events: data from the URRAH (URic acid Right for heArt Health) study.
2021
Objective Although the relationship between hyperuricemia and cardiovascular events has been extensively examined, data on the role of diuretic-related hyperuricemia are still scanty. The present study was designed to collect information on the relationship between diuretic-related hyperuricemia and cardiovascular events. Methods The URic acid Right for heArt Health (URRAH) study is a nationwide, multicentre, observational cohort study involving data on individuals recruited from all the Italy territory under the patronage of the Italian Society of Hypertension with an average follow-up period of 122.3 ± 66.9 months. Patients were classified into four groups according to the diuretic use (y…
Undertreatment of dyslipidemia: from the Arabian Gulf to the USA. Time to solve this problem!
2014
Undertreatment of dyslipideamia is a universal problem and reduces the efficasy of hypolipidaemic drugs to reduce cardiovascular event rates. The means to face this problem are available and should be utilized to optimize dyslipidaemia control and clinical outcomes.
