The gut microbiota - a modulator of endothelial cell function and a contributing environmental factor to arterial thrombosis.
2019
Introduction: There is emerging evidence linking the commensal gut microbiota with the development of cardiovascular disease and arterial thrombosis. In immunothrombosis, the host clotting system protects against the dissemination of invading microbes, not considering the huge number of microbes that interact with host physiology in a mutualistic fashion. Areas covered: Interestingly, recent research revealed that colonizing gut microbes profoundly influence host innate immune pathways that support arterial thrombus growth. The gut microbiota promotes arterial thrombus formation by enhancing the pro-adhesive capacity of the vascular endothelium, triggering hepatic von Willebrand factor synt…
Lipid profile during pregnancy in HIV-infected women
2006
Purpose: We investigated the evolution of serum lipid levels in HIV-infected pregnant women and the potential effect of antiretroviral treatment during pregnancy using data from a national surveillance study. Method: Fasting lipid measurements collected during routine care in pregnancy were used, analyzing longitudinal changes and differences in lipid values at each trimester by protease inhibitors (Pls) and stavudine use. Multivariate analyses were used to control for simultaneous factors potentially leading to hyperlipidemia. Study population included 248 women. Results: Lipid values increased progressively and significantly during pregnancy: mean increases between the first and third tri…

Contenido preventivo en la negociación colectiva
2021
espanolEn este trabajo se realiza un analisis cualitativo y cuantitativo de los convenios colectivos de ambito estatal de los dos ultimos anos y medio en cuanto a la regulacion que contienen sobre la materia de seguridad y salud laboral. En este sentido, se procede a estudiar con detalle la regulacion convencional sobre la formacion, vigilancia de la salud, organos de representacion de los trabajadores, colectivos con proteccion especial y nuevos riesgos emergentes, en concreto, el acoso moral. Se concluye en general, que, desafortunadamente, y aunque se ha conseguido un avance importante al respecto, en los momentos actuales, y en general, la materia preventiva aun no ha tenido un adecuado…

Current trends on the determination of organic UV filters in environmental water samples based on microextraction techniques – A review
2018
UV filters are a group of cosmetic ingredients commonly used in a wide variety of cosmetic products to protect users from UV solar radiation. They belong to different chemical families, such as benzophenones, p-aminobenzoates, salicylates, cinnamates, benzotriazoles, benzimidazoles, camphor derivatives, triazines, etc. These cosmetic ingredients are considered as emerging contaminants since they easily reach the aquatic environment, where they are accumulated causing harmful effects in the flora and fauna despite being present at the ng L-1 level. Therefore, the development of sensitive and selective analytical methods for their environmental surveillance monitoring is of high interest. In …
Use of Nanomaterial-Based (Micro)Extraction Techniques for the Determination of Cosmetic-Related Compounds
2020
The high consumer demand for cosmetic products has caused the authorities and the industry to require rigorous analytical controls to assure their safety and efficacy. Thus, the determination of prohibited compounds that could be present at trace level due to unintended causes is increasingly important. Furthermore, some cosmetic ingredients can be percutaneously absorbed, further metabolized and eventually excreted or bioaccumulated. Either the parent compound and/or their metabolites can cause adverse health effects even at trace level. Moreover, due to the increasing use of cosmetics, some of their ingredients have reached the environment, where they are accumulated causing harmful effec…
Antigens and immunoevasins: opponents in cytomegalovirus immune surveillance
2002
CD8+ T cells are the main effector cells for the immune control of cytomegaloviruses. To subvert this control, human and mouse cytomegaloviruses each encode a set of immune-evasion proteins, referred to here as immunoevasins, which interfere specifically with the MHC class I pathway of antigen processing and presentation. Although the concerted action of immunoevasins prevents the presentation of certain viral peptides, other viral peptides escape this blockade conditionally or constitutively and thereby provide the molecular basis of immune surveillance by CD8+ T cells. The definition of viral antigenic peptides that are presented despite the presence of immunoevasins adds a further dimens…
Mobilità, sicurezza e nuove frontiere tecnologiche
2018
Mobilità, sicurezza e nuove frontiere tecnologiche sono settori che hanno ormai assunto un ruolo trainante nell’evoluzione/trasformazione del diritto penale e processuale penale dei paesi occidentali, e segnatamente di quelli europei. Su di essi si è incentrato un Modulo Jean Monnet svolto, tra il 2015 e il 2018, presso il Dipartimento di Giurisprudenza dell’Università di Palermo, che ha visto alternarsi, in qualità di relatori, tanto esperti di caratura internazionale quanto giovani studiosi e dottorandi. Questo libro contiene alcuni dei loro contributi: una raccolta che, se certo non esaurisce la trattazione della varietà e complessità di profili che ciascuno dei tre ambiti problematici p…
Geochemical monitoring of groundwaters (1998-2001) at Vesuvius volcano (Italy)
2004
This work presents the results of hydrogeochemical studies carried out at Vesuvius during the period May 1998-December 2001, mostly focusing on compositional time variations observed during this time. Based on their chemistry, groundwater samples are distinguished into two groups, 1 and 2, representative of water circulation in the southern and northern sectors of the volcano, respectively. Waters from group 1 are typically more acidic, warmer, and more saline than those of group 2. They also have higher CO2 and CH4 contents, attributed to enhanced input of deep-rising volatiles and prolonged water-rock interactions. Time-series highlight the fairly constant chemical composition of the enti…
