Seruma pepsinogēna un gastrīna - 17 noteikšanas diagnostiska vērtība kuņģa vēža gadījumā
2017
Kuņģa vēzis ir piektais biežākais ļaundabīgs audzējs un trešais biežākais ar vēzi saistītās nāves cēlonis pēc plaušu un kolorektālā vēža pasaulē. Ik gadu pasaulē tiek jaunreģistrēti aptuveni viens miljons slimības gadījumu. Latvijā 2015. gadā jaunreģistrēti bija 583 kuņģa vēža gadījumi, kas ir augsta slimības incidence Latvijas populācijā. Vīriešiem kuņģa vēzi diagnosticē vidēji divas reizes biežāk nekā sievietēm. Liela daļa slimības gadījumu tiek atklāta vēlīnās stadijās, kas pasliktina pacientu prognozi. Ar kuņģa vēzi saistītu pirmsvēža stāvokļu noteikšanai rietumu valstīs piedāvā lietot neinvazīvus testus, nosakot asins serumā pepsinogēnu I un II attiecību, gastrīna-17 līmeni un H.pylori…
The role of microbial ecology during biogas production from renewable energy sources. Characterizing microbial community structures in bioenergy prod…
2019
La Microbiología tiene un rol fundamental en la integración de procesos para la recuperación de nutrientes, energía y agua durante el tratamiento biológico del agua residual. La identificación de los grupos microbiológicos clave, así como de sus dinámicas, ecología y estructuras microbianas, mejorará el entendimiento de los procesos que integran las futuras plantas de recuperación de recursos, conocidas por sus siglas en inglés como Water Resource Recovery Facilities (WRRF). Este conocimiento podría ser de gran utilidad durante la optimización de sistemas anaerobios que recuperan energía a partir de fuentes de biomasa renovables. Hasta la fecha, diferentes estudios han demostrado que la com…
Towards a new protocol for field measurements of greenhouse gases from wastewater treatment plant
2016
Emissions into the atmosphere of greenhouse gases (GHGs), i.e., carbon dioxide, methane and nitrous oxide from wastewater treatment plants are of increasing concern in the water industry. In order to produce useful and comparable information for monitoring, assessing and reporting GHG emissions from wastewater treatment plants, there is a crescent need for a general accepted methodology. This paper aims at proposing the first protocol for monitoring and accounting GHG emissions from wastewater treatment plants taking into account both direct and internal indirect emissions focusing on sections known to be major responsible of GHG emissions i.e. oxidation tanks and sludge digestion. The main…
Installazioni idrauliche nell’area sacra a Sud del tempio di Zeus Olympios ad Agrigento
2020
This paper will test the relationship between water and cult in the southern part of the sanctuary of Zeus Olympios at Agrigento. The most singular feature of this area is a monumental pool, besides some cisterns, buildings and a small oikos temple. The sacred area was investigated during the 20th century by E. Gabrici and E. De Miro and was referred to a chthonian cult, without deepening the features and modalities of ritual activities. Besides, it was not considered at all as a part of the sanctuary of Zeus, depending on the late chronology assigned to the main buildings. After having defined the character of the context through an analysis of the architectural remains, the votive and rit…
Ginger and Turmeric Essential Oils for Weed Control and Food Crop Protection
2019
Ginger and turmeric are two food ingredients that are in high demand due to their flavor and positive effects on health. The biological properties of these spices are closely related to the aromatic compounds they contain. The chemical compositions of their essential oils and their in vitro phytotoxic activity against weeds (Portulaca oleracea, Lolium multiflorum, Echinochloa crus-galli, Cortaderia selloana, and Nicotiana glauca) and food crops (tomato, cucumber, and rice) were studied. Forty-one compounds, accounting for a relative peak area of 87.7% and 94.6% of turmeric and ginger essential oils, respectively, were identified by Gas Chromatography&ndash
Microgastrinae (Hymenoptera: Braconidae) in the Forest State of Artikutza (Navarra: Spain): Diversity and Community Structure
2013
Microgastrinae is one of the largest subfamilies of the Braconidae with about 2,000 described species worldwide. These wasps are of enormous ecological interest due to their role in controlling the caterpillar populations. This study analyses diversity and community structure within the Microgastrinae in the Artikutza Forest, located in the Peñas de Aia Natural Park, western Pyrenees, Spain. The specimens were collected in two different habitats: mixed forest and beech forest. A total of 524 specimens, belonging to nine separate genera and 27 species were captured. Alpha, beta and gamma diversity were analyzed. Additionally, the relationship between Microgastrinae phenology and climatic con…
Predominance of Type 1 Innate Lymphoid Cells in the Rectal Mucosa of Patients With Non-Celiac Wheat Sensitivity: Reversal After a Wheat-Free Diet.
2016
OBJECTIVES: Non-celiac wheat sensitivity (NCWS) is defined as a reaction to ingested wheat after exclusion of celiac disease and wheat allergy. As its pathogenesis is incompletely understood, we evaluated the inflammatory response in the rectal mucosa of patients with well-defined NCWS. METHODS: The prospective study included 22 patients with irritable bowel syndrome (IBS)-like clinical presentation, diagnosed with NCWS by double-blind placebo-controlled challenge. Eight IBS patients not improving on wheat-free diet were used as controls. Two weeks after oral challenge was performed with 80 grams of wheat daily, cells were isolated from rectal biopsies and thoroughly characterized by fluore…
Discorso turistico-enologico sull’aura in ‘Un’ottima annata’ di Ridley Scott
2023
This essay follows fits into an ongoing project dedicated to highlighting the rhetorical and ideological representations of food and wine in cinema It carries out a semiotic analysis of the film A good year (by Ridley Scott, with the aim of identifying the role that wine plays in it and in the touristic imaginary about it. The essay pursues this goal by facing the issue of authenticity in tour ism as posed by Culler and by reconstructing the implicit aesthetic and touristic theory on which the film may be positioned. Then, it proceeds by getting into a reconstruction of the ideologic role played by the settings and the spaces represented in it. A spatial dialectic among city and country get…
Online ^{222}Rn removal by cryogenic distillation in the XENON100 experiment
2017
International audience; We describe the purification of xenon from traces of the radioactive noble gas radon using a cryogenic distillation column. The distillation column was integrated into the gas purification loop of the XENON100 detector for online radon removal. This enabled us to significantly reduce the constant$^{222}$ Rn background originating from radon emanation. After inserting an auxiliary$^{222}$ Rn emanation source in the gas loop, we determined a radon reduction factor of $R\,>\,27$ (95% C.L.) for the distillation column by monitoring the$^{222}$ Rn activity concentration inside the XENON100 detector.
