Clinical justification of dental radiology in adult patients: A review of the literature
2007
Although the radiological doses used by dentists are low individually, patients are often exposured to many repeat dental radiographic examinations. The ‘routine’ use of dental radiography, such as screening of all patients using dental panoramic radiography (DPRs) or a random decision to take a dental radiograph, will inevitable lead to unnecessary patient exposure. The use of Radiographic Referral Criteria has now become a legal requirement for all practitioners following the adoption of European Legislation. All exposures to x-rays should be clinically justified and each exposure should be expected to give the patient a positive net benefit. Recently the European Commission has published…
Vecchie e nuove minoranze: definizioni e strumenti di tutela
2018
This papers studies different issues related to minorities rights. After trying to define what should be intended as minorities in contemporary West societies and exploring if it is possible to make a difference between old and new minorities, the research focuses on the main issues that are at stake. In particular, the paper aims at discovering which are the rights involved and how such rights can be categorised, as human, cultural, individual or community rights. The research will show how new minorities are in need of having their own identities recognised and protected by our West societies. This requires the achievement of a real process of integration to be carried out through two com…
LH administration as a potential strategy for ovarian protection and female fertility preservation against highly gonadotoxic chemotherapy
2022
Els ovaris contenen una reserva de fol·licles no renovable, que produeixen un únic ovòcit fecundable a cada cicle menstrual al llarg de l'etapa reproductiva femenina (15-49 anys), però que disminueix progressivament amb l'edat. Per tant, els factors que afecten negativament la dotació de fol·licles provocaran una reducció significativa de la vida reproductiva en la dona. Les teràpies oncològiques basades en l'administració de quimioteràpia alquilant s'utilitzen habitualment per a tractar els càncers ginecològics en pacients joves, però amb freqüència acceleren l'esgotament de la reserva fol·licular i l'aparició de la menopausa. Els efectes secundaris de la quimioteràpia sobre la fertilitat,…
UV filters: From sunscreens to human body and the environment
2007
Recognition of the harmful effects of ultraviolet (UV) radiation on the skin has triggered development of organic chemicals (commonly referred as UV filters) that can absorb UV radiation and attenuate the negative effects of sunlight exposure. Depending on the properties and the intended degree of protection, a wide array of combinations is being marketed as delivering protection against most kinds of UV-induced skin damage. However, some UV filters have dermatological implications, so maximum applicable concentrations have been established. To monitor to what extent commercial products comply with the mandatory limits, several analytical methods have been used for their determination in co…
Achieving agreement on service needs in child protection : Comparing children’s, mothers’ and practitioners’ views over time and between approaches
2022
Purpose While studies on service users’ participation and their perceptions on the quality of services exist, agreement between family members’ and practitioners’ assessments of the family’s situation has received less interest. The purpose of this paper is to investigate agreement and its effect on outcomes by comparing the viewpoints of three groups of informants (children, mothers and practitioners) in the context of statutory child protection in two study groups – one applying a systemic approach (SPM) and a service-as-usual control group (SAU). Design/methodology/approach A quasi-experimental repeated-measures study design was applied. Outcome data comprised 112 cases (SPM cases n = 5…
Ocena przestrzennego rozmieszczenia parków narodowych i obszarów chronionego krajobrazu w państwach Europy Środkowej na tle prowincji fizycznogeograf…
2020
Na podstawie analizy przestrzennego rozmieszczenia parków narodowych i obszarów chronionego krajobrazu Polski (parki krajobrazowe), Czech, Słowacji i Węgier oceniono czy tworzone w poszczególnych krajach systemy ochrony przyrody i krajobrazu są reprezentatywne również dla prowincji fizycznogeograficznych w granicach państw. Stwierdzono znaczną reprezentatywność w prowincjach głównie górskich i wskazano na dalsze możliwości ochrony. Na podstawie oceny stopnia integracji systemów ochrony przyrody i krajobrazu w rejonach przygranicznych określono obszary, które powinny uzupełnić system. Między poszczególnymi krajami występują różnice w przestrzennej organizacji parków narodowych i obszarów och…
Diversifying crop rotations with temporary grasslands: potentials for weed management and farmland biodiversity
2010
Fruchtfolgen können dazu dienen, die kontinuierliche Selektion von Unkrautarten zu verhindern, die an eine bestimmte Kultur angepasst sind. Dies könnte dem Unkrautmanagement, der Einsparung von Herbiziden, und der Biodiversität dienen. Heutige, sehr einfache Furchtfolgen könnten durch mehrjährige Futterkulturen diversifiziert werden. Die Einflüsse solcher mehrjähriger Kulturen auf Unkräuter wurden in vier Ansätzen untersucht : 1) Vegetationsaufnahmen auf 632 Feldern in Westfrankreich zeigten, dass die Unkrautzusammensetzung zwischen mehrjährigen Futterkulturen und einjährigen Kulturen stark variiert. Der Vergleich von Feldern vor, während und nach mehrjährigen Futterkulturen legte nahe, das…
Radiation protection of patients undergoing high-dose-rate brachytherapy: peripheral dose estimation, review of radiation risks and implant shielding…
2015
La braquiterapia (BT) es una modalidad de tratamiento de radioterapia en la que se coloca una fuente radiactiva encapsulada cerca, en contacto o en el interior del volumen a tratar. La desintegración de esta fuente produce la emisión de energía, lo que puede dar lugar a la muerte celular. Una dosis absorbida muy elevada (la dosis absorbida se define como la energía absorbida por unidad de masa) se deposita en un corto período de tiempo y en un pequeño número de fracciones. Para poder realizar un tratamiento de BT se requiere que el volumen de tratamiento sea accesible y bien delimitado en tamaño y forma. La BT se utiliza comúnmente como una modalidad de tratamiento eficaz para el cáncer de …

Targeted Drug Delivery in Plants: Enzyme‐Responsive Lignin Nanocarriers for the Curative Treatment of the Worldwide Grapevine Trunk Disease Esca
2019
Abstract Nanocarrier (NC)‐mediated drug delivery is widely researched in medicine but to date has not been used in agriculture. The first curative NC‐based treatment of the worldwide occurring grapevine trunk disease Esca, with more than 2 billion infected plants causing a loss yearly of $1.5 billion, is presented. To date, only repetitive spraying of fungicides is used to reduce chances of infection. This long‐term treatment against Esca uses minimal amounts of fungicide encapsulated in biobased and biodegradable lignin NCs. A single trunk injection of <10 mg fungicide results in curing of an infected plant. Only upon Esca infection, ligninolytic enzymes, secreted by the Esca‐associated fu…
