Natural Products as Modulators of Apoptosis and their Role in Inflammation
2006
ABSTRACT: Modifications in apoptosis, a programmed form of cell death that participates in a wide variety of physiological processes, can contribute to many diseases, principally those associated with cell accumulation, such as inflammation. One hallmark of inflammation is the infiltration of leukocytes, which are programmed to undergo apoptosis at inflamed tissues. Resolution of inflammation thus involves the elimination of excess inflammatory cells by physiological cell death and the subsequent removal of apoptotic cells by phagocytes. Controlling this process may therefore be useful in the treatment of pathologies, which include an inflammatory component. Interestingly, while in some cas…
Childhood intermittent and persistent rhinitis prevalence and climate and vegetation: a global ecologic analysis
2014
Abstract Background The effect of climate change and its effects on vegetation growth, and consequently on rhinitis, are uncertain. Objective To examine between- and within-country associations of climate measures and the normalized difference vegetation index with intermittent and persistent rhinitis symptoms in a global context. Methods Questionnaire data from 6- to 7-year-olds and 13- to 14-year-olds were collected in phase 3 of the International Study of Asthma and Allergies in Childhood. Associations of intermittent (>1 symptom report but not for 2 consecutive months) and persistent (symptoms for ≥2 consecutive months) rhinitis symptom prevalences with temperature, precipitation, vapor…
The International Study of Asthma and Allergies in Childhood (ISAAC) Phase Three: A global synthesis
2013
This ISAAC Phase Three synthesis provides summarised information on the main findings of the study, regional tables and figures related to the prevalence and severity of current symptoms of asthma, rhinoconjunctivitis and eczema in the main regions of the world. The large number of surveyed children (≈1,200,000), the large number of centres (233) and countries (98) that participated in ISAAC Phase Three makes this study the most comprehensive survey of these diseases ever undertaken. Globally, the prevalence for current asthma, rhinoconjunctivitis and eczema in the 13-14-year age group was 14.1%, 14.6% and 7.3%, respectively. In the 6-7-year age group the prevalence for current asthma, rhin…
The effect of fractal contact lenses on peripheral refraction in myopic model eyes.
2014
Purpose: To test multizone contact lenses in model eyes: Fractal Contact Lenses (FCLs), designed to induce myopic peripheral refractive error (PRE). Methods: Zemax ray-tracing software was employed to simulate myopic and accommodation-dependent model eyes fitted with FCLs. PRE, defined in terms of mean sphere M and 90–180 astigmatism J180, was computed at different peripheral positions, ranging from 0 to 35 in steps of 5, and for different pupil diameters (PDs). Simulated visual performance and changes in the PRE were also analyzed for contact lens decentration and model eye accommodation. For comparison purposes, the same simulations were performed with another commercially available conta…

Prenatal exposure to perfluoroalkyl substances, immune-related outcomes, and lung function in children from a Spanish birth cohort study.
2019
Background: Prenatal exposure to perfluoroalkyl substances (PFASs) has been associated with impaired immune and respiratory health during childhood but the evidence is inconsistent and limited for lung function. We studied the association between prenatal PFASs exposure and immune and respiratory health, including lung function, up to age 7 years in the Spanish INMA birth cohort study. Methods: We assessed four PFASs in maternal plasma samples collected during the 1st trimester of pregnancy (years: 2003-2008): perfluorohexane sulfonate (PFHxS), perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), and perfluorononanoate (PFNA). Mothers reported the occurrence (yes/no) of lower respir…
Attitudes and perceptions of faculty members in the process adopting innovation: The OpenCourseWare initiative at the University of Valencia, Spain
2014
The OpenCourseWare project, an open learning resource repository, was established at the University of Valencia between 2008 and2009. It initially consisted of only 10 subjects, none of which was in the field of Health Sciences. The objective of this research was toinvestigate the attitudes and perceptions of faculty members in the field of Health Sciences with regard to the project to identify strategies to increase its use and expand its coverage. We applied Rogers’ innovation-diffusion theory along with a qualitative approach using theoretical sampling, semi-structured interviews and open coding. The results indicate the existence of two categories of faculty members. In the first group,…
Constructions with shell nouns in English: their dual role in information packaging

Les construccions encapsuladores en anglès i la doble funció en l'emmagatzematge de la informació
 Aquest treball se centra en les propietats funcionals i estructurals d’un tipus de fórmules focals en anglès: les construccions del tipus N-be-that (Schmid 2001), com en The problem is that he is jealous, a les quals denominem fórmules amb encapsuladors (FFSNs, segons la denominació en anglès). La funció dels noms en aquest patró consisteix a crear closques conceptuals (Schmid 1997) dins de les quals s’encapsula el contingut proposicional, una operació afavorida pel vincle coreferencial que hi ha entre les dues parts del patró. Les dades proporcionades pel BNC mostren dues manifestacions …
Transporta radītā trokšņa līmeņa spektrālais novērtējums
2015
Satiksmes troksnis pēdējos gados kļuvis par globālu piesārņojuma problēmu pilsētvidē, un ir nozīmīgākais vides trokšņa piesārņojuma avots lielākajās aglomerācijās visā pasaulē. Troksnis negatīvi ietekmē cilvēku labsajūtu un veselību, dabas procesus, un var atstāt ietekmi arī uz nekustamā īpašuma vērtību. Darba ietvaros, izmantojot tiešo mērījumu metodi, veikti autotransporta radītā kopējā trokšņa mērījumi un tā spektrālo komponenšu īpatsvara novērtējums atšķirīgos meteoroloģiskajos apstākļos un transporta kustības režīmos, novērtējot lokālās izplatības tendences un sorbējošo virsmu ietekmi. Pētījums veikts intensīvas ceļu satiksmes posmā Rīgā, Juglas ielas posmā – Biķernieku iela – Lubānas …
Lipīdus pazeminošās terapijas efektivitāte Latvijas Ģimenes hiperholesterinēmijas reģistra pacientiem: pēcpārbaudes dati
2019
Ģimenes hiperholesterinēmija (ĢH) ir bieži sastopama, pārmantojama slimība, kas raksturojas ar izteikti palielinātu zema-blīvuma lipoproteīnu holesterīna (ZBLH) līmeni kopš bērnības. Tā izraisa agrīnu koronāru sirds slimību, kuras pirmā izpausme bieži ir miokarda infarkts vai pēkšņa koronāra nāve. Hipolipidemizējoša terapija ir ārstēšanas stūrakmens, bet ņemot vērā izteikti palielinātu ZBLH koncentrāciju, tā mērķa sasniegšana ir apgrūtinoša un nereti neiespējama. Mērķis: Raksturot hipolipidemizējošas terapijas efektivitāti ĢH pacientiem pirms un pēc iekļaušanas Latvijas Ģimenes hiperholesterinēmijas reģistrā (LĢHR). Metodes: Tika analizēta informācija par LĢHR pacientiem, kuri vērsās vai bi…
