Impact of immunodepression and moderate alcohol consumption on coronary and other arterial disease events in an 11-year cohort of HIV-infected patien…
2012
Objective To investigate the relationship between response to antiretroviral therapy (ART), alcohol use and occurrence of a major coronary or other arterial disease event (CADE) in HIV-infected individuals. Design A cohort study. A Cox model was used to identify the correlates of a first occurrence of a major CADE. Setting The French ANRS CO8 APROCO-COPILOTE cohort was set up in 1997 to study clinical progression and patient-reported outcomes (PRO) after initiating a protease inhibitor-containing ART. Clinical data were retrieved from medical records. Self-administered questionnaires collected data on PRO and behaviours, including alcohol use. Participants Metabolic data were only available…

Varieties of algebras with pseudoinvolution and polynomial growth
2017
Let A be an associative algebra with pseudoinvolution (Formula presented.) over an algebraically closed field of characteristic zero and let (Formula presented.) be its sequence of (Formula presented.) -codimensions. We shall prove that such a sequence is polynomially bounded if and only if the variety generated by A does not contain five explicitly described algebras with pseudoinvolution. As a consequence, we shall classify the varieties of algebras with pseudoinvolution of almost polynomial growth, i.e. varieties of exponential growth such that any proper subvariety has polynomial growth and, along the way, we shall give also the classification of their subvarieties. Finally, we shall de…
Old sleeping Sicilian beauty: seed germination in the palaeoendemic Petagnaea gussonei (Spreng.) Rauschert (Saniculoideae, Apiaceae).
2015
Petagnaea gussonei (Apiaceae) is a perennial herbaceous species endemic to northeast Sicily (Nebrodi Mountains). It is considered a remnant of the Sicilian Tertiary flora, and is endangered according to the Red List. There is no information in the literature about the germinability of its seeds, even though seed production is know to occur. The aim of this study was to obtain data to better understand seed germination of this species and its biological implications. Thus, several approaches were employed: vitality analyses, gibberellic acid supply, germination and soil microbial flora analyses via end-point and qPCR. The results suggest that seed germination occurs after ca. 1.5 years at a …
Fēču mikrobiotas raksturojums un to ietekmējošie faktori bērniem
2020
Ievads. Agrīna mikrobiotas attīstība ietekmē gan imūnsistēmas nobriešanu, gan dažādu patoloģiju, kā, piemēram, alerģijas, infekciju un citu slimību attīstību bērnībā, tāpēc nepieciešams identificēt mikrobiotas sastāva atšķirības un to ietekmējošos agrīnos riska faktorus bērniem. Darba mērķis. Pētīt fēču mikrobiotas sastāvu pirmsskolas vecuma bērniem un analizēt to ietekmējošos faktorus. Materiāli un metodes. Šķērsgriezuma pētījums veikts primārajos veselības aprūpes centros. Bērnu (līdz piecu gadu vecumam) vecākiem tika lūgts aizpildīt anketu (demogrāfiskie dati, dzimšanas veids, barošana pirmajā dzīves gadā, antibakteriāla terapija mātei laktācijas laikā, ģimenes dati) un atnest bērna fēču…
Recurrent inoculation: a strategy for a better survival of Pseudomonas fluorescens strain in soil
2022
A growing interest is shown for microbial inoculants as a promising alternative to agrochemicals for sustainable agricultural. However, biotic and abiotic stresses are known to affect their establishment and effectiveness, leading to inconsistent performance in field conditions. At the same time, a poor survival of the strain is often observed, which constitutes a main hamper for bacterial inoculant development. We hypothesize that recurrent inoculations would improve the survival of the strain in soil. For this purpose, we tested different scenarios of inoculation of the plant growth promoting rhizobacteria Pseudomonas fluorescens in soil microcosms: a single inoculation, two inoculations …
Stability of the human microbiome. Health and disease imprinted in the time variability of the human microbiota.
2019
Animal microbiota plays an essential role in keeping the physiological status of the host healthy. This microbiota consists of hundreds of different species that inhabit the host, and whose composition varies on a daily basis due to multiple factors as diets, medicine intakes, lifestyle or diseases. It is a highly dynamical system that shows variability even when the host is in a healthy condition, but visible changes happen when the system is perturbed. Thus, the main objective of this thesis aimed to study the temporal variability of human microbiota, and link it to the health status of the host. For this, we proposed a formal definition of stability in microbial systems based on the use …
Amoksicilīna un klaritromicīna kombinētās terapijas ilgtermiņa ietekme uz zarnu trakta mikrobiomu
2018
Helicobacter pylori ir viens no pirmajiem identificētajiem bakteriālajiem karcinogēniem un Eiropas medicīnas pārstāvju izstrādātās vadlīnijas iekļauj eradikācijas shēmu, kurā ietilpst kombinēta plaša spektra antibiotiku pielietošana. Antibakteriālā terapija, it īpaši plaša spektra antibiotiku pielietošana rada risku īstermiņa un ilgtermiņa zarnu trakta mikrobioma disbiozes attīstībai. Maģistra darba mērķis bija noskaidrot Helicobacter pylori kombinētās antibakteriālās terapijas izraisītās ilgtermiņa izmaiņas zarnu trakta mikrobiomā. Pētījuma gaitā tika veikta 45 pacientu 16s rRNS amplikonu analīze, salīdzinot pirms un pēc terapijas iegūtos fēču paraugus. Ilgtermiņa antibakteriālās terapijas…
16S rRNS gēna vairāku un divu mainīgo reģionu mikrobioma rekonstrukcijas algoritmu iegūto rezultātu salīdzināšana
2022
16S rRNS marķiergēna sekvencēšana ir viena no plašāk izmantotākajām un lētākajām mikrobioma taksonomiskā profila rekonstruēšanas metodēm. Taču, īso sekvencēšanas nolasījumu dēļ, visi gēna mainīgie reģioni nevar tikt nolasīti vienlaicīgi, bet tos nolasot atsevišķi zūd katra atsevišķā reģiona sasaiste ar pārējiem molekulas reģioniem kā arī par katru var tikt iegūts atšķirīgs datu apjoms, kas ierobežo kopējo mikrobioma kopas profilēšanas izšķirtspēju. Šajā darbā tiek aplūkota varbūtiskās rekonstrukcijas algoritma pieeja, kura izmanto vairāku 16S rRNS gēna reģionu noleases datus un maksimālās iespējamības varbūtisko algoritmu mikrobioma taksonomiskā profila rekonstrukcijai. Izmantojot Short MUl…
