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…
Ethyl hexanoate transfer in paper and plastic food packaging by sorption and permeation experiments
2008
The barrier properties of one treated paper packaging and one standard plastic film (bi-oriented polypropylene, biOPP) were assessed for ethyl hexanoate. Three methods based either on sorption (gravimetry and micro-atmosphere-derived method) or permeation kinetic determination were used in controlled conditions of aroma vapor concentration (107 Pa), temperature (25 degrees C) and relative humidity (about 0 %). Ethyl hexanoate solubility values were on the same range of magnitude for both packaging films in spite of their different nature and composition. Ethyl hexanoate affinity for both films was well predicted by their respective solubility parameters. Solubility values were different acc…
Nelle terre esterne. Geografie, paesaggi, scritture
2018
Il volume esplora il rapporto tra geografia e letteratura, prendendo in esame opere di Sbarbaro, Calvino, Biamonti, Manzoni, Stoppani e Gadda. Scopo del saggio è mostrare le corrispondenze complesse tra spazio geografico e spazio del testo, isolando un paradigma ermeneutico operativo nel concetto di paesaggio.
Do gender wage differences within households influence women's empowerment and welfare? : Evidence from Ghana
2021
Using household data from the latest wave of the Ghana Living Standards Survey, this paper utilizes machine learning techniques – IV LASSO – that allows for the treatment of unconfoundedness in the selection of observables and unobservables to examine the structural effect of gender wage differences within households on women's empowerment and welfare in Ghana. The structural parameters of the IV LASSO estimations show that a reduction in household gender wage gap significantly enhances women's empowerment. Also, a decline in household gender wage gap results meaningfully in improving household and women's welfare. Particularly, the increasing effect on women's welfare resulting from decrea…
Reliability of Frail and Barthel Tests for Detecting Frailty in Palliative Oncological Patients in a Home Hospitalization Unit: A Comparative Study.
2022
Cancer is a condition that can increase the risk of frailty. In addition, palliative oncological patients in home hospitalization can find their activities of daily living affected. The main objective was to measure the degree of frailty in the oncological population in home hospitalization comparing Barthel and Frail-VIG Indexes. This is a descriptive cross-sectional study. A sample of oncological patients in home hospitalization (n = 50) that included 27 men and 23 women were recruited, and disability due to frailty was measured using the VIG frailty index and the Barthel scale for Activities of Daily Living (ADLs). Spearman’s correlation coefficients were categorized as weak (rs &l…
Characterization of palm sap harvested in Songkhla province, Southern Thailand
2010
International audience; The purpose of this study was to characterise the quality of palm sap after harvested in Songkhla province, southern Thailand. Ten palm sap samples were analyzed. The results showed differed in physical and chemical quality among samples (P<0.05). The results showed range of L*, a* and b* values between 61.49 to 87.53, 1.46 to 3.52 and 12.41 to 19.31, respectively. The turbidity was ranged from 39.56% to 79.95%. The pH value was varied from 4.19 to 5.23, while total acidity was ranged from 0.27% to 0.93%. The total soluble solids ranged from 10.80 to 17.40OBrix. Total and reducing sugars were varied in a range of 10.36% to 16.94% and 0.88% to 3.56%, respectively. The…
Utilidad diagnóstica de la ecografía abdominal con contraste en la patología inflamatoria digestiva
2014
La ecografía abdominal con contraste (EAC) es una nueva técnica que ofrece información de la microvascularización de los órganos intraabdominales (asas intestinales, páncreas, hígado,…), lo que la hace idónea para explorar la inflamación de los mismos. El objetivo del presente proyecto es analizar la utilidad de esta técnica en la valoración de la patología inflamatoria digestiva centrándose en dos trastornos inflamatorios de gran relevancia clínica: la enfermedad de Crohn (EC), proceso inflamatorio crónico, y la pancreatitis aguda (PA), proceso inflamatorio agudo. La hipótesis del trabajo es que las medidas cuantitativas del realce intestinal o pancreático tras la administración intravenos…
The Effect of Smartphone-Based Cognitive Training on the Functional/Cognitive Markers of Schizophrenia: A One-Year Randomized Study
2020
Background: Cognitive impairment is associated with long-term disability that results in the deterioration of both the social and professional status of individuals with schizophrenia. The impact of antipsychotic therapy on cognitive function is insufficient. Cognitive training is therefore proposed as a tool for cognitive rehabilitation in schizophrenia. In this study we investigated the effect of self-administered cognitive training using a smartphone-based application on the cognitive function of paranoid schizophrenia patients focusing on response time, correct answer rate, incorrect answer rate, and fatigability to check, if these functions can be functional markers of successful cogni…
A parasitoloxia e a doutrina do contáxio animado: a helmintiase e a sarna na España do século XIX
1990
Les explicacions parasitològiques del contagi eren tant teòriques com observacionals. La triquinosi, la sarna i la helmintiasi van ser exemples primerencs que van demostrar un contagi viu. A principis del segle XIX, en la medicina espanyola, igual que en la medicina europea, es rebutjava el contagi animat excepte en el cas d'alguns paràsits animals com la sarna. En uns altres, com en la helmintiasi intestinal, s'acceptava el seu origen viu, però no la seua contagiositat, i es defensava la seua generació espontània fins a ben entrat el segle XIX. En el “Diccionari de Ciències Mèdiques”, l'estudi dels cucs és quasi exclusivament morfològic i es defensa com a causa de la seua presència en l'ho…
MILKER’S NODULE. A PERPLEXING FARMYARD INFECTION AND THREAT TO THE IMMUNOCOMPROMISED
2017
Milker’s nodules, also called paravaccinia, is a DNA virus transmitted from infected cows to humans. It results from contact with cattle, cattle byproducts, or fomites. Classified as an occupational disorder, those at risk of exposure include farmers, butchers, and agricultural tourists. The viral infection begins 5—15 days after inoculation as an erythematous-purple, round nodule with a clear depressed center, and a surrounding erythematous ring. While familiar to those in farming communities, the presence of the nodule may be concerning to others, particularly the immunosuppressed. Milker’s nodules are selflimited in immunocompetent individuals and heal without scarring within 8 weeks. An…
