How Hox genes can shed light on the place of echinoderms among the deuterostomes.
2014
19 pages; International audience; BACKGROUND: The Hox gene cluster ranks among the greatest of biological discoveries of the past 30 years. Morphogenetic patterning genes are remarkable for the systems they regulate during major ontogenetic events, and for their expressions of molecular, temporal, and spatial colinearity. Recent descriptions of exceptions to these colinearities are suggesting deep phylogenetic signal that can be used to explore origins of entire deuterostome phyla. Among the most enigmatic of these deuterostomes in terms of unique body patterning are the echinoderms. However, there remains no overall synthesis of the correlation between this signal and the variations observ…
Echinoderm Antimicrobial Peptides
2016
Abstract Antimicrobial peptides (AMPs) are widely expressed in organisms and have been linked to innate and acquired immunity in vertebrates. These compounds are constitutively expressed from different cellular types to interact directly with infectious agents and/or modulate immunoreactions. In invertebrates, including echinoderms, which lack a vertebrate-type adaptive immune system, AMPs represent the major humoral defense system against infection, showing a diverse spectrum of action mechanisms, most of them related to plasma membrane disturbance and lethal alteration of microbial integrity. Here, we summarize the knowledge of AMPs in echinoderms as Strongylocins identified in the sea ur…
Dezinfekcijas līdzekļu un individuālo aizsarglīdzekļu ietekme uz māsas pašsajūtu ķirurģijas nodaļā
2022
Bakalaura darba tēmas nosaukums ir “Dezinfekcijas līdzekļu un individuālo aizsarglīdzekļu ietekme uz māsas pašsajūtu ķirurģijas nodaļā”. Ņemot vērā, ka dezinfekcijas līdzekļi tiek ražoti koncentrētāki, kā arī individuālie aizsarglīdzekļi tiek pielietoti aizvien vairāk, to pielietojums ir paredzēts, lai aizsargātu māsas un citu ārstniecības personāla un pacienta veselību, tomēr šie līdzekļi var ietekmēt māsas pašsajūtu- pasliktinot gan fizisko, gan psihoemocionālo stāvokli, tad par bakalaura darba mērķi tika izvirzīts- noskaidrot dezinfekcijas līdzekļu un individuālo aizsarglīdzekļu lietošanas ietekmi uz māsas pašsajūtu ķirurģijas nodaļā. Uzsākot pētījuma darbu, tika izvirzīts arī pētījuma j…
Self-concept and adaptation to illness in pediatric diabetic patients
2014
Nuestro objetivo es estudiar el autoconcepto y la adaptación a la enfermedad en pacientes pediátricos diabéticos. Como instrumentos de evaluación se utilizaron el registro ad-hoc para las variables sociodemográficas y de enfermedad, el cuestionario de Autoconcepto Garley (CAG) y cuestionario de respuesta adaptativa a la enfermedad en pacientes diabéticos. La muestra constó de 23 sujetos evaluados en un único momento de medida, todos ellos niños y adolescentes entre 8 y 16 años de edad. Los resultados muestran cómo aproximadamente el 50% de niños y adolescentes con diabetes tipo I presentan un autoconcepto bajo en la mayoría de las dimensiones estudiadas, destacando cómo cerca del 30% de los…
Imaging of Hepatic Focal Nodular Hyperplasia: Pictorial Review and Diagnostic Strategy
2016
Focal nodular hyperplasia (FNH) is the second most common benign solid liver lesion after hemangioma, occurring more frequently in young women. The prime differential diagnoses include hepatocellular adenoma, hepatocellular carcinoma, and hypervascular metastasis. As the management of FNH is typically conservative, imaging plays a key role in diagnostic pathway, and misdiagnosis may have a major clinical effect. In this article, we describe the ultrasound, computed tomography, and magnetic resonance imaging features of FNH, underlining the importance of typical radiological features that allow a specific noninvasive diagnosis. We present a large spectrum of a typical imaging findings that F…
Boron-Doped Diamond Electrodes for Electroorganic Chemistry
2011
Boron-doped diamond (BDD) electrodes provide an unusually wide electrochemical window in protic media, since there exist large offset potentials for the evolution of molecular hydrogen and oxygen, respectively. At the anode, alcohols are specifically converted to alkoxyl radicals. These can be used for chemical synthesis. When the enormous reactivity of such intermediate spin centers is not controlled, mineralization or electrochemical incineration dominates. Efficient strategies include either high substrate concentrations or fluorinated alcohols which seem to stabilize the spin centers in the course of reaction.

Intestinal tuberculosis as a cause of chronic diarrhoea among patients with human immunodeficiency virus infection: report of two cases.
2001
In Western countries human immunodeficiency virus infection is considered the main risk factor of tuberculous disease, its incidence being 500 times higher in HIV-infected patients than in the general population. Despite the disease frequently present in these patients with extraintestinal manifestations, intestinal localization is rarely observed and often as a consequence of complications such as acute gastrointestinal bleeding or perforation. The diagnosis of intestinal tuberculosis is difficult and is often delayed due to the lack of specific signs and symptoms as well as the low sensitivity of routine methods. A review of the literature is made and personal experience in the diagnosis …
"Ab initio" structure solution from electron diffraction data obtained by a combination of automated diffraction tomography and precession technique
2009
Using a combination of our recently developed automated diffraction tomography (ADT) module with precession electron technique (PED), quasi-kinematical 3D diffraction data sets of an inorganic salt (BaSO(4)) were collected. The lattice cell parameters and their orientation within the data sets were found automatically. The extracted intensities were used for "ab initio" structure analysis by direct methods. The data set covered almost the complete set of possible symmetrically equivalent reflections for an orthorhombic structure. The structure solution in one step delivered all heavy (Ba, S) as well as light atoms (O). Results of the structure solution using direct methods, charge flipping …
Impact of the community structure on the dynamics of complex networks
2023
Networks are everywhere. We encounter them daily in our lives, through our social interactions, how we come up with decisions in our brain, to having phone calls, conducting financial transactions, and traveling from one place to another. Individual actions are influenced by their environment, which is, in turn, influenced by the network's topology. Notably, individuals may change their actions, ideas, or opinions to conform to the aspirations of a particular social group. In the same vein, the spread of a virus can take a certain course if the network's structure induces specific pathways for expansion. In such scenarios, communities substantially impact the evolution of the dynamics. They…
