ICTV Virus Taxonomy Profile: Pseudoviridae
2021
Pseudoviridae is a family of reverse-transcribing viruses with long terminal repeats (LTRs) belonging to the order Ortervirales. Pseudoviruses are commonly found integrated in the genomes of diverse plants, fungi and animals and are broadly known as Ty1/Copia LTR retrotransposons. Inside the cell, they form icosahedral virus particles, but unlike most other viruses, do not have an extracellular phase. This is a summary of the ICTV Report on the family Pseudoviridae, which is available at ictv.global/report/pseudoviridae.
What Is the Role of Minimally Invasive Mitral Valve Surgery in High-Risk Patients? A Meta-Analysis of Observational Studies
2016
Background. Minimally invasive valve surgery is related to certain better postoperative outcomes. We aimed to assess the role of minimally invasive mitral valve surgery in high-risk patients. Methods. A systematic literature review identified eight studies of which seven fulfilled criteria for metaanalysis. Outcomes for a total of 1,254 patients (731 were conventional standard sternotomy and 523 were minimally invasive mitral valve surgery) were submitted to meta-analysis using random effects modeling. Heterogeneity and subgroup analysis with quality scoring were assessed. The primary end point was early mortality. Secondary end points were intraoperative and postoperative outcomes and long…
Malignant Scalp Tumors: Retrospective Analysis of 1000 Patients.
2022
Abstract Background: Limited data on large cohort of patients with malignant tumors of the scalp are available in the literature. e aim of this study was to review a large cohort of patients with malignant scalp tumors to determine epidemilogy, tumor characteristics of this region and treatment. Materials and Method: A retrospective review of patients with malignant scalp tumors diagnosed histopathologically between 2005 and 2021 was performed. Demographic features and tumor characteristics were analyzed. Results: A total of 1080 patients (M: F 3,5:1) were treated and followed up for a mean period of 42 months (12-120 months). Age at diagnosis ranged from 12 to 98 years. Most malignant scal…
Spike-in SILAC proteomic approach reveals the vitronectin as an early molecular signature of liver fibrosis in hepatitis C infections with hepatic ir…
2014
Hepatitis C virus (HCV)-induced iron overload has been shown to promote liver fibrosis, steatosis, and hepatocellular carcinoma. The zonal-restricted histological distribution of pathological iron deposits has hampered the attempt to perform large-scale in vivo molecular investigations on the comorbidity between iron and HCV. Diagnostic and prognostic markers are not yet available to assess iron overload-induced liver fibrogenesis and progression in HCV infections. Here, by means of Spike-in SILAC proteomic approach, we first unveiled a specific membrane protein expression signature of HCV cell cultures in the presence of iron overload. Computational analysis of proteomic dataset highlighte…
Traditional Chinese herbal medicine at the forefront battle against COVID-19: Clinical experience and scientific basis.
2020
Abstract Background Throughout the 5000-year history of China, more than 300 epidemics were recorded. Traditional Chinese herbal medicine (TCM) has been used effectively to combat each of these epidemics’ infections, and saved many lives. To date, there are hundreds of herbal TCM formulae developed for the purpose of prevention and treatment during epidemic infections. When COVID-19 ravaged the Wuhan district in China in early January 2020, without a deep understanding about the nature of COVID-19, patients admitted to the TCM Hospital in Wuhan were immediately treated with TCM and reported later with >90% efficacy. Approach We conducted conduct a systematic survey of various TCM herbal pre…
Effectiveness and safety of a new helmet CPAP configuration allowing tidal volume monitoring in patients with COVID-19.
2021
Abstract Background High generated tidal volumes (Vt) have been correlated with higher risk of self-induced lung injury and worse clinical outcome. This study aimed to evaluate the effectiveness and safety of a new helmet continuous positive airway pressure delivered (h-CPAP) configuration allowing Vt monitoring in patients affected by COVID-19. Methods This prospective observational study was performed in the respiratory intermediate care unit of University Hospital in Turin, Italy, between March 24th, and June 15th, 2020. Included patients were treated with CPAP via a single-limb intentional leak configuration by a turbine-driven ventilator, provided with a dedicated patch. Effectiveness …
Saīsinājumu lietojums tekstos par tirgvedību
2020
Šīs pētījums ir veltīts saīsinājumu lietošanas analīzei tirgvedības tekstos. Pētījuma mērķis ir iznalizēt literatūru par saīsinājumu veidiem, kā arī identificēt saīsinājumu izmantošanu tekstos par tirgvedību, analizēt to frekvenci un norādīt izmantošanas mērķi. Pētījumā tika analizēti 40 tirgvedības raksti, kuri publicēti no 2019. līdz 2020. gadam. Tika izmantotas gan kvalitatīvas, gan kvantitatīvas izpētes metodes. Rezultāti liecina, ka izvēlētajos tekstos tiek izmantoti tādi saīsinājumu veidi kā iniciālismi, akronīmi, abreviācijas un burtu un ciparu kombinācijas tips. Turklāt pētījumā konstatēts, ka lielākā daļa saīsinājumu, ko izmanto analizētajos rakstos, ir saistīti ar tirgvedību vai t…
Widespread diminishing anthropogenic effects on calcium in freshwaters
2019
Calcium (Ca) is an essential element for almost all living organisms. Here, we examined global variation and controls of freshwater Ca concentrations, using 440 599 water samples from 43 184 inland water sites in 57 countries. We found that the global median Ca concentration was 4.0 mg L−1 with 20.7% of the water samples showing Ca concentrations ≤ 1.5 mg L−1 , a threshold considered critical for the survival of many Ca-demanding organisms. Spatially, freshwater Ca concentrations were strongly and proportionally linked to carbonate alkalinity, with the highest Ca and carbonate alkalinity in waters with a pH around 8.0 and decreasing in concentrations towards lower pH. However, on a temporal…
Nestandarta pareizrakstība Instagram sludinājumos
2020
Tā kā patērētāju attieksme un cerības ir mainījušās, tradicionālā reklāmdošana ir zaudējusi daļu savas pievilcības un vērtības, liekot reklāmdevējiem meklēt jaunu pieeju. Tiešsaistes reklāmas ir īpaši efektīvas un populāras tādu sociālo mediju vietnēs kā Instagram, kas iesaista auditoriju komunikācijā un nodibina attiecības ar reklāmdevēju. Lai gan attēli ir nozīmīga daļa Instagram reklāmās, arī pievienotie ziņojumi ir svarīgi un bieži vien satur nestandarta pareizrakstību. Šī darba mērķis ir izpētīt nestandarta pareizrakstības lietojumu, nozīmi un funkcijas tiešsaistes reklāmās sociālo mediju vietnē Instagram, izmantojot diskursa analīzi kā galveno pētījuma metodi. Kvalitatīvā un kvantitat…
Oxygen parameters of blood: Definitions and symbols
1990
Definitions and symbols for relevant parameters of the oxygen status of arterial blood are recommended. The recommendations are as simple as possible, easy to understand, and devoid of misinterpretations and double meanings. The authors propose no new definitions for limited new methods, no combination of symbols and methods, and no association between definition, symbol and commercial name.
