Possible role of ABO system in age-related diseases and longevity: a narrative review
2014
ABO blood group antigens are expressed either on the surface of red blood cells either on a variety of other cells. Based on the available knowledge of the genes involved in their biosynthesis and their tissue distribution, their polymorphism has been suggested to provide intraspecies diversity allowing to cope with diverse and rapidly evolving pathogens. Accordingly, the different prevalence of ABO group genotypes among the populations has been demonstrated to be driven by malaria selection. In the similar manner, a particular ABO blood group may contribute to favour life-extension via biological mechanisms important for surviving or eluding serious disease. In this review, we will suggest…
Limit on the diffuse flux of ultrahigh energy tau neutrinos with the surface detector of the Pierre Auger Observatory
2009
Data collected at the Pierre Auger Observatory are used to establish an upper limit on the diffuse flux of tau neutrinos in the cosmic radiation. Earth-skimming ντ may interact in the Earth's crust and produce a τ lepton by means of charged-current interactions. The τ lepton may emerge from the Earth and decay in the atmosphere to produce a nearly horizontal shower with a typical signature, a persistent electromagnetic component even at very large atmospheric depths. The search procedure to select events induced by τ decays against the background of normal showers induced by cosmic rays is described. The method used to compute the exposure for a detector continuously growing with time is de…
Akcionāru vai dalībnieku līguma tiesiskais statuss.
2018
Pētījumā “Akcionāru vai dalībnieku līguma tiesiskais statuss” maģistra darba autore ir apskatījusi akcionāru vai dalībnieku līguma tiesisko regulējumu Latvijas Republikā, tā vēsturisko attīstību, galvenos jautājumus un esošo tiesu praksi.

Epidemiology of congenital diaphragmatic hernia in Europe: a register-based study.
2015
INTRODUCTION: Published prevalence rates of congenital diaphragmatic hernia (CDH) vary. This study aims to describe the epidemiology of CDH using data from high-quality, population-based registers belonging to the European Surveillance of Congenital Anomalies (EUROCAT).METHODS: Cases of CDH delivered between 1980 and 2009 notified to 31 EUROCAT registers formed the population-based case series. Prevalence over time was estimated using multilevel Poisson regression, and heterogeneity between registers was evaluated from the random component of the intercept.RESULTS: There were 3373 CDH cases reported among 12 155 491 registered births. Of 3131 singleton cases, 353 (10.4%) were associated wit…
Anorectal malformations and pregnancy-related disorders: a registry-based case-control study in 17 European regions
2013
Objective To identify pregnancy-related risk factors for different manifestations of congenital anorectal malformations (ARMs).Design A population-based case-control study.Setting Seventeen EUROCAT (European Surveillance of Congenital Anomalies) registries, 1980-2008.Population The study population consisted of 1417 cases with ARM, including 648 cases of isolated ARM, 601 cases of ARM with additional congenital anomalies, and 168 cases of ARM-VACTERL (vertebral, anal, cardiac, tracheo-esophageal, renal, and limb defects), along with 13371 controls with recognised syndromes or chromosomal abnormalities.Methods Multiple logistic regression analyses were used to calculate adjusted odds ratios …
Ibn Sab'in
2011
‘Abd al-Haqq ibn Sab‘ı¯n was born in the Ricote Valley, near Cieza, in the Kingdom of Murcia sometimes between the year 613 and 614 of the Hegira (1216 or 1217 CE). He studied Arabic, Andalusi literature, logic and philosophy, medicine, alchemy, white magic, and the ‘‘Science of Names and Letters.’’ At that time Ibn Khala¯s: was the qadi of Ceuta. He chose Ibn Sab‘ın to answer the philosophical questions sent by the emperor Frederick II of Hohenstaufen. It has been contended that Ibn Sab‘ı¯n was forced to leave his new hometown after answering the emperor’s arguments. What seems more likely, however, is that his Sufi ideas were not very popular with the political chief of the town. The time…
Attuali orientamenti nella diagnosi e nel trattamento delle aderenze placentari patologiche: la nostra esperienza
2010
The abnormal adherence of the placenta is a disease characterized by an anomalous miometrial infiltration of Chorionic villi. This event blocks the regular detachment of placenta in post partum and sometimes a severe bleeding that causes the urgency of a caesarean section. In the past years the incidence of this pathology has increased to about 1 in 500/600 deliveries. The cause of abnormal adherence of placenta is unknown but there are some risk factors such as prior caesarean sections, women older than 35 years of age and placenta previa. The early diagnosis is very important and it can be done by Eco-Color-doppler (eventually associated with 3d technique) and Magnetic Resonance. Objectiv…
Modeling the anaerobic treatment of sulfate rich urban wastewater. Application to AnMBR technology
2020
[EN] Although anaerobic membrane bioreactors (AnMBR) are a core technology in the transition of urban wastewater (UWW) treatment towards a circular economy, the transition is being held back by a number of bottlenecks. The dissolved methane released from the effluent, the need to remove nutrients (ideally by recovery), or the energy lost by the competition between methanogenic and sulfate-reducing bacteria (SRB) for the biodegradable COD have been identified as the main issues to be addressed before AnMBR becomes widespread. Mathematical modeling of this technology can be used to obtain further insights into these bottlenecks plus other valuable information for design, simulation and contro…
Application of the General Model "Biological Nutrient Removal Model No.1" to upgrade two full-scale WWTPs
2012
In this paper, two practical case studies for upgrading two wastewater treatment plants (WWTPs) using the general model BNRM1 (Biological Nutrient Removal Model No. 1) are presented. In the first case study, the Tarragona WWTP was upgraded by reducing the phosphorus load to the anaerobic digester in order to minimize the precipitation problems. Phosphorus load reduction was accomplished by mixing the primary sludge and the secondary sludge and by elutriating the mixed sludge. In the second case study, the Alcantarilla WWTP, the nutrient removal was enhanced by maintaining a relatively low dissolved oxygen concentration in Stage A to maintain the acidogenic bacteria activity. The VFA produce…
