Evaluation of ergonomic factors and postures that cause muscle pains in dentistry students’ bodies

2015

Background: Work-related musculoskeletal disorders commonly experienced by dental professionals are one of the main occupational health problem affecting their health and well-being.This study was conducted to evaluate ergonomic factors and profession-related postures and also investigate relationship between demographic factors and work condition with pain in dental students. Material and Methods: 60 freshman and sophomore dentistry students were randomly chosen as the subjects of control group, and 60 of 5th and 6th-year students were selected as the members of exposure group. Data related to the subjects such as sex, doing exercise, severity of musculoskeletal pain were obtained through …

Ensuring food safety using aptamer based assays: Electroanalytical approach

2020

Aptamers, are being increasingly employed as favorable receptors for constructing highly sensitive biosensors, for their remarkable affinities towards certain targets including a wide scope of biological or chemical substances, and their superiority over other biologic receptors. The selectivity and affinity of the aptamers have been integrated with the wise design of the assay, applying suitable modifications, such as nanomaterials on the electrode surface, employing oligonucleotide-specific amplification strategies or, their combinations. After successful performance of the electrochemical aptasensors for biomedical applications, the food sector with its direct implication for human healt…

Impact and effectiveness of risk mitigation strategies on the insurability of nanomaterial production: evidences from industrial case studies.

2014

Workers involved in producing nanomaterials or using nanomaterials in manufacturing plants are likely to have earlier and higher exposure to manufactured/engineered nanomaterials (ENM) than the general population. This is because both the volume handled and the probability of the effluence of ‘free’ nanoparticles from the handled volume are much higher during a production process than at any other stage in the lifecycle of nanomaterials and nanotechnology‐enabled products. Risk assessment (RA) techniques using control banding (CB) as a framework for risk transfer represents a robust theory but further progress on implementing the model is required so that risk can be transferred to insuranc…

State surveillance as a threat to personal security of individuals

2015

Changes in modern society are crucial to individuals. Article starts with analysis of control in nowadays societies. Then author tries to understand useful categories, as "Panopticon", "ban-opticon" and "synopticon". Last part is focused on stete surveillance, i.e. surveillance by American National Security Agency.

La opinión pública ante la vigilancia masiva de datos. El difícil equilibrio entre acceso a la información y seguridad nacional

2015

RESUMEN: La transparencia y el acceso a la información convierten a la sociedad en una participante activa del proceso de rendición de cuentas de los poderes públicos. Pero, esa libertad informativa tiene límites, como lo es el secreto que necesariamente impone, en la mayor parte de las ocasiones, la salvaguarda de la seguridad nacional. El secreto - y por lo tanto, la excepción a la regla general de la publicidad- tiene como misión impedir que se conozcan ciertas actividades de inteligencia, que recaban y tratan información con la finalidad de garantizar el éxito de determinadas acciones de los servicios de inteligencia-defensa o de prevenir riesgos. En este trabajo se aborda la difícil co…

Sanitizing food contact surfaces by the use of essential oils

2018

Chemical sanitizers continue to be widely used by the food industry to disinfect food contact surfaces. However, as some chemical disinfectants have been reported to produce unhealthy by-products, alternative and natural compounds need to be investigated. To this end, nine essential oils (EOs) were screened to develop a natural sanitizing solution (SAN) for disinfecting food contact surfaces. Once extracted, their antimicrobial activity and chemical composition were determined. An exploratory multivariate approach was used to investigate the relationships between the chemical and microbiological data sets. Among the tested EOs, Thymbra capitata EO, containing up to 93.31% oxygenated monoter…

Randomized Comparative Trial with Ceftizoxime and Cefotaxime in Urinary Tract Infections

1984

Ceftizoxime, a new, semisynthetic, beta-lactamase-resistant cephalosporin, is not metabolized in man and is excreted almost entirely as the original active compound in the urine. The efficacy and safety of ceftizoxime were assessed in 80 patients with acute and chronic urinary infections, with and without associated pathological conditions, in comparison with cefotaxime. Two dosage schedules, 1 g or 0.5 g every 12 h, i.v. or i.m. for 10 days, were adopted according to the severity of each case and to separate randomization tables for each schedule; causal agents were all sensitive to both drugs in vitro. The overall results were excellent. Safety was excellent in almost all cases. In this t…

New Families as an Educational Emergency

2017

One phenomenon typical of late-modern Western societies is the extreme pluralisation of family forms, a true and proper archipelago of families, so that: the family can no longer be reasonably discussed in the singular, just as well as each couple seems to form a «mixed couple» . Observing the data describing this phenomenon and any perceived trends, prompt a first general consideration, from an educational perspective: the aspects related to couple formation, the choice of whether to marry, the preferred family forms, all highlight a breakup between the older and the younger generations. In short, we are confronted with a new culture of human relationships: this new culture sets new symbol…

International and multicenter real‐world study of sorafenib‐treated patients with hepatocellular carcinoma under dialysis

2020

Background & Aims: Information on safety and efficacy of systemic treatment in patients with hepatocellular carcinoma (HCC) under dialysis are limited due to patient exclusion from clinical trials. Thus, we aimed to evaluate the rate, prevalence, tolerability, and outcome of sorafenib in this population. Methods: We report a multicenter study comprising patients from Latin America and Europe. Patients treated with sorafenib were enrolled; demographics, dose modifications, adverse events (AEs), treatment duration, and outcome of patients undergoing dialysis were recorded. Results: As of March 2018, 6156 HCC patients were treated in 44 centres and 22 patients were concomitantly under dial…
