A retrospective study of the prevalence and characteristics of dens invaginatus in a sample of the Turkish population.
2012
Objective: The purpose of this study was to assess the prevalence of dens invaginatus and to classify the types of dens invaginatus in a sample of the Turkish population.. Study Design: A retrospective study was performed using periapical and panoramic radiographs of 5355 patients who presented to the Department of Oral Diagnosis and Radiology at the Ondokuz Mayıs University Dentistry Faculty between January 2009 and December 2010. Maxillary and mandibular anterior teeth were evaluated for the presence and characteristics of dens invaginatus. Statistical evaluation of the presence of dens invaginatus related to gender was performed by the Pearson chi-squared test. Results: Dens invaginatus …

The frequency and characteristics of idiopathic osteosclerosis and condensing osteitis lesions in a Turkish patient population.
2009
The objective of this study was to investigate the frequency of idiopathic osteosclerosis (IO) and condensing osteitis (CO) in a Turkish patient population, considering factors such as age and sex of the population, in addition to shape and localization, as well as the dental relationship between IO and CO lesions.A retrospective study was performed using panoramic radiographs of 6,154 patients ranging in age from 5 to 69 years old, who had been subjected to dental treatment. Descriptive characteristics of radiopacities, including shape, localization and dental relationship were recorded. The Chi-squared test was used.A total of 238 radiopacities were detected, which included 185 IO lesions…
Sporting habits of urban runners: Classification according to their motivation
2019
This study analyses the sporting habits of runners participating in short-distance urban running events to identify groups with different motivations towards the practice of endurance running and participation in urban running events. A sample consisting of 937 participants in the Valencia running circuit was interviewed using a questionnaire consisting of a scale of 22 items to analyse their motives for participating in popular races. An exploratory and confirmatory factorial analysis was carried out to check the validity of the instrument, and the analysis identified the following four factors into which the indicators were grouped: psychological and physical motives (3 items), social mot…
Prognostic Relevance of Cardiorespiratory Fitness as Assessed by Submaximal Exercise Testing for All-Cause Mortality: A UK Biobank Prospective Study
2020
Objective: To investigate if the inverse associations of cardiorespiratory fitness (CRF) with all-cause and cardiovascular mortality in the general population vary among individuals who are at different pre-test risk. Patients and Methods: CRF was assessed through submaximal bike tests in 58,892 participants aged 40-69 years who completed baseline questionnaires between January 1, 2006 and December 31, 2010 in the UK Biobank study. Participants were categorized into risk categories, which determined allocation to an individualized bike protocol. These were “minimal risk (1)”, “small risk (2)” and “medium risk (3)” groups (i.e., those who cycled at 50%, 35% of predicted maximal workload and …
Response of the aging eye to first day of modern material contact lens wear
2018
Objectives: To investigate the ocular surface of an aged population wearing a daily disposable contact lens over their first day of wear. Methods: Forty eyes from forty presbyopic subjects were fitted a daily CL (Delefilcon A). Tear osmolarity, tear meniscus area (TMA) and ocular surface aberrations (total higher order root means square (RMS)) were assessed at baseline (t0), at 20 minutes (t1) and after 8 hours (t2) of wear. Fluorescein corneal and conjunctival staining and tear break up time (TBUT) were performed at t0 and t2. Results: No statistically significant changes were found between t0, t1 and t2 for TMA, and between t0 and t2 for fluorescein corneal and conjunctival staining. TBUT…

2020
espanolIntroduccion: la modernizacion de la sociedad ha supuesto una serie de cambios en los habitos alimentarios y la practica de actividad fisica de la poblacion, asi como una mayor generacion de desperdicios alimentarios en los hogares. Objetivo: estudiar el desperdicio de alimentos en el hogar, valorando al mismo tiempo los habitos alimentarios y estilos de vida de la poblacion estudiante universitaria. Material y metodos: los datos se recopilaron mediante una encuesta estructurada y autoadministrada online en la que se midieron los habitos alimentarios (cuestionario de frecuencia) y el nivel de actividad fisica (IPAQ-Short) de los sujetos participantes, asi como el desperdicio de alime…
Urinary metals and metal mixtures and oxidative stress biomarkers in an adult population from Spain: The Hortega Study
2019
Introduction: Few studies have investigated the role of exposure to metals and metal mixtures on oxidative stress in the general population. Objectives: We evaluated the cross-sectional association of urinary metal and metal mixtures with urinary oxidative stress biomarkers, including oxidized to reduced glutathione ratio (GSSG/GSH), malondialdehyde (MDA), and 8‑oxo‑7,8‑dihydroguanine (8-oxo-dG), in a representative sample of a general population from Spain (Hortega Study). Methods: Urine antimony (Sb), barium (Ba), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), molybdenum (Mo), vanadium (V) and zinc (Zn) were measured by ICPMS in 1440 Hortega Study participants. Results: The geomet…
sE-cadherin is upregulated in serum of patients with renal cell carcinoma and promotes tumor cell dissemination in vitro
2019
Abstract Introduction Cadherin family proteins are involved in the tumorigenesis of several malignancies. However, their significance in renal cell carcinoma (RCC) has not been extensively investigated. The current study investigates the potential of several cadherins to perform as biomarkers for tumor detection and exert functional RCC activity. Methods Pre- and postoperative concentrations of sE-cadherin, cadherin-6, N-cadherin, cadherin-11, cadherin-17, and cadherin-5 were measured in serum of patients undergoing surgery for RCC and correlated to clinical and histopathological parameters. Control serum was obtained from healthy volunteers. A498 and Caki-1 cells were incubated with sE-cad…
Increased Vaccination Coverage among Adolescents and Young Adults in the District of Palermo as a Result of a Public Health Strategy to Counteract an…
2018
During the summer of 2016 four cases of invasive meningococcal disease in rapid succession among young adults in the district of Palermo, Italy, resulting in one death, were widely reported by local and national mass media. The resultant ‘epidemic panic’ among the general population overloaded the vaccination units of the Palermo district over the following months. Strategies implemented by the Sicilian and local public health authorities to counteract ‘meningitis fear’ included the following: (a) extension of active and free-of-charge anti-meningococcal tetravalent vaccination from age class 12–18 to 12–30 years old; (b) implementation of vaccination units during normal clinic hours in roo…
