miRNAs in the metaplastic transformation of the esophagus: something in the way toward carcinogenesis.
Background: Barrett's esophagus (BE) is a precancerous lesion that predisposes to development of esophageal adenocarcinoma (EAC) and it is associated with gastroesophageal reflux disease. Genetic changes involved in the metaplastic progression from squamous esophageal mucosa toward Barrett’s metaplasia and adenocarcinoma are almost unknown and there is an increasing interest in the developing of more objective biomarkers that can improve risk prediction. Several evidences suggest that some miRNAs are differentially expressed in the BE and EAC. Among them, miR-143, miR-145, miR-194, miR-203, miR-205, miR-215 appear to have a key role in the metaplasia and in neoplastic progression. Aim: The …
Pre-operative leukocytosis: a potential poor prognosis risk factor in cardiac device implantation: a case report
2022
Introduction. Despite the benefits of the implantation of cardiac rhythm management devices cardiac implantable electronic device (CIED) infection is an emerging problem New debate emerged about the unclear role of the pre-operative alteration of pro-inflammatory parameters, such as leukocytosis, in the development CIED infection and/or heart failure, and its consequent impact on the timing of ICD implantation/reimplantation. Case report. A 65 years old patient with a history of Diabetes Mellitus (DM) type II, ventricular and supraventricular arrhythmias, chronic myocardial ischemia, heart failure was admitted to hospital.Healthcare workers opted for ICD implantation despite the presence of…
Light on the molecular and cellular mechanisms of bicuspid aortic valve to unveil phenotypic heterogeneity
2019
Research on bicuspid aortic valve disease (BAV) and related complications has grown in an exponential manner in the last decades. However, the current knowledge of the mechanisms underlying the development of this disease is still limited, since all clinical and surgical studies on BAV mainly focused their objects on its major vascular complications, such as ascending aortic aneurysms and dissection. It is now clear that a better understanding of the pivotal molecular and cellular pathophysiological aspects of bicuspid valve aortopathy, including natural history, phenotypic expression, histology, cellular mechanisms and pathways, is critical for improving its clinical management. This chang…
Taxonomy and conservation ofPancratium maritimum(Amaryllidaceae) and relatives in the Central Mediterranean
2015
Pancratium maritimum L. (Amaryllidaceae) is a geophyte occurring in the Mediterranean region, from the Black Sea to part of the Atlantic coast. This plant is receiving much attention from the international scientific community due to its value as a bioindicator, the potential industrial value of its chemical compounds, and its use as a commercial ornamental plant. Plant morphometry and sequences of three plastid DNA regions (rbcL, matK, trnH-psbA) were used to assess the phenotypic and genetic variability of this taxon and its closest congeneric species (in particular Pancratium linosae, from the volcanic island of Linosa) in the Central Mediterranean (Sicily, Tunisia and surrounding island…
Ustekinumab therapy changes the transcriptional activity pattern of TGF-β1–3 genes
2019
Introduction One of the examples of genes whose expression can be altered by the action of ustekinumab is TGF-β. It is a pleiotropic cytokine whose activity affects psoriatic changes and the state of homeostasis of the whole organism. Aim To evaluate the effect of ustekinumab on the transcriptional activity of TGF-b family genes in patients with psoriatic arthritis and to check whether the results obtained can be helpful in monitoring the progress of treatment. Material and methods From total PBMCs obtained from peripheral blood of 14 patients with psoriatic arthritis, total RNA was isolated. The expression level of the TGF-β1, TGF-β2 and TGF-β3 genes was determined by RT-qPCR in real time.…

Sediment quality of the ecoregion Engure, Gulf of Riga, assessed by using ecotoxicity tests and biomarker responses
2014
Pētījuma mērķis bija novērtēt Engures ekoreģiona (Rīgas līča rietumu piekrastes) sedimentu kvalitāti, izmantojot sedimentu ekotoksicitātes testus. Lai noteiktu bioloģiskās atbildes reakcijas uz dažāda veida stresoriem, kā testorganismi pielietotas sānpeldes Monoporeia affinis and Pontogammarus robustoides, un izvēlēti biomarķieri (AChE, GST, GR, CAT, MT), kas noteikti gliemenēs Macoma balthica. Engures ekoreģionu varētu uzskatīt par nepiesārņotu rajonu, jo tā sedimentus raksturo salīdzinoši zemas smago metālu koncentrācijas. Engures ekoreģiona sedimentu ekotoksicitātes testu rezultāti neuzrādīja statistiski būtisku (>20% mirstība) toksisko efektu. Testorganismu izdzīvotība bija robežās no 8…
Concentrations of metallothionein in the bivalve molluscsAnodonta spp.andUnio spp.from Latvian lakes with different anthropogenic pressure
2013
Concentrations of metallothioneins (MT) were analysed in bivalve molluscs Anodonta spp. and Unio spp. from 6 lakes and watercourses of Latvia with different anthropogenic pressure. The aim of the study was to find the relationship between MT in molluscs and concentrations of heavy metals in sediments. Unio spp. and Anodonta spp. showed no significant differences in the concentrations of MT. High concentrations of heavy metals (Cd, Pb, Hg, Cu, Zn) were detected in the deepest parts of polluted water bodies, however their concentrations significantly decreased in near shore sediments inhabited by molluscs. Only Zn tends to accumulate in the molluscs, reaching 2-7 times higher concentrations i…
