Comprehensive Analysis of Invasive and Noninvasive Investigation Methods in Peripheral Artery Disease
2019
Abstract Peripheral artery disease of the lower limbs is, in fact, an arterial pathology, by which the blood flow is reduced, due to the obstruction caused by the deposit of atheroma plaques.(1) This deposition occurs slowly, which leads to a slow progression of the disease, and thus, at the onset of symptomatology. The objective of the study was to make a comparison between the invasive and noninvasive paraclinical investigations performed in patients with peripheral arterial disease of the lower limbs in the E.C.C.H. Sibiu. In conclusion, between the two investigations (computed tomography angiography and digital subtraction angiography) there are no noticeable differences in the terminal…
Novel, automated, semi-industrial modular photobioreactor system for cultivation of demanding microalgae that produce fine chemicals - The next story…
2021
Abstract Recently, there has been increased interest in the use of microorganisms in the production of pharmaceuticals, nutraceuticals and energy supply products, which is due to their rapid growth rate and ability to biosynthesize fine chemicals or biotransform specific xenobiotics. To achieve the desired scale of production and optimization of microbial cultures, it is necessary to design bioreactors that enable process automation, control of working parameters, reduction of microbial and chemical contaminations, and culture independence of climate conditions. In response to this need, an original, modular airlift-type photobioreactor system was designed and manufactured. This novel semit…
Genomic characterization of a local epidemic Pseudomonas aeruginosa reveals specific features of the widespread clone ST395
2017
International audience; Pseudomonas aeruginosa is a ubiquitous opportunistic pathogen with several clones being frequently associated with outbreaks in hospital settings. ST395 is among these so-called 'international' clones. We aimed here to define the biological features that could have helped the implantation and spread of the clone ST395 in hospital settings. The complete genome of a multidrug resistant index isolate (DHS01) of a large hospital outbreak was analysed. We identified DHS01-specific genetic elements, among which were identified those shared with a panel of six independent ST395 isolates responsible for outbreaks in other hospitals. DHS01 has the fifth largest chromosome of …
Antiinflammatory Therapy with Canakinumab for Atherosclerotic Disease
2017
Background: Experimental and clinical data suggest that reducing inflammation without affecting lipid levels may reduce the risk of cardiovascular disease. Yet, the inflammatory hypothesis of atherothrombosis has remained unproved. Methods: We conducted a randomized, double-blind trial of canakinumab, a therapeutic monoclonal antibody targeting interleukin-1β, involving 10,061 patients with previous myocardial infarction and a high-sensitivity C-reactive protein level of 2 mg or more per liter. The trial compared three doses of canakinumab (50 mg, 150 mg, and 300 mg, administered subcutaneously every 3 months) with placebo. The primary efficacy end point was nonfatal myocardial infarction, …
Reference interval of monocyte distribution width (MDW) in healthy blood donors.
2020
Abstract Background The aim of the study was to accurately establish the reference interval (RI) of monocyte distribution width (MDW) in healthy blood donors by the direct method using different statistical approaches. Methods MDW was measured in 486 subjects. RI of MDW was calculated by the non-parametric method, the robust method and, the Harrell-Davis bootstrap method and using different tests to identify potential outliers (Dixon-Reed and Tukey). Results Lower and upper reference limits of the RI calculated by the non-parametric method were, 16.22 (90%CI 15.78–16.47) – 23.15 (90%CI 22.80–24.10) (without outlier removal), and 16.44 (90%CI 16.21–16.67) – 22.99 (90%CI 22.33–23.22) (after o…
Genome-Wide Estimation of the Spontaneous Mutation Rate of Human Adenovirus 5 by High-Fidelity Deep Sequencing
2016
Rates of spontaneous mutation determine the ability of viruses to evolve, infect new hosts, evade immunity and undergo drug resistance. Contrarily to RNA viruses, few mutation rate estimates have been obtained for DNA viruses, because their high replication fidelity implies that new mutations typically fall below the detection limits of Sanger and standard next-generation sequencing. Here, we have used a recently developed high-fidelity deep sequencing technique (Duplex Sequencing) to score spontaneous mutations in human adenovirus 5 under conditions of minimal selection. Based on >200 single-base spontaneous mutations detected throughout the entire viral genome, we infer an average mutatio…
Impact of colonic fermentation on sterols after the intake of a plant sterol-enriched beverage: A randomized, double-blind crossover trial
2017
Summary Background Cholesterol microbial transformation has been widely studied using in vitro fermentation assays, but less information is available on the biotransformation of plant sterols (PS). The excretion percentage of animal sterols (AS) (67–73%) is considerably greater than that of PS (27–33%) in feces from healthy humans following a Western diet. However, a lower content of AS in feces from subjects following a vegetarian, vegan or low-fat animal diet has been seen when compared to omnivorous subjects. Although only one human study has reported fecal sterol excretion after the consumption of PS-enriched food (8.6 g PS/day), it was found that the target group showed an increase in …
A single preoperative pain neuroscience education: Is it an effective strategy for patients with carpal tunnel syndrome?
2019
Patients undergoing carpal tunnel release surgery may continue to experience pain despite the intervention. This symptom may be modulated by psychosocial factors including depression, catastrophic thinking, and kinesiophobia. Pain neuroscience education (PNE) has been found to be effective when combined with therapeutic exercise in patients with chronic pain, but this strategy has not been evaluated in patients with persistent hand pain. The findings of this study indicate that a single preoperative PNE session in combination with therapeutic exercise does not provide added benefits in comparison to standard preoperative care plus therapeutic exercise. Future studies should evaluate if pati…
The largest caucasian kindred with dentatorubral-pallidoluysian atrophy: A founder mutation in italy
2019
BACKGROUND: Dentatorubral-pallidoluysian atrophy is a hereditary neurodegenerative disease prevalently reported in Japan but rare in Caucasians. The objective of this study was to reconstruct the pedigree of Italian dentatorubral-pallidoluysian atrophy familial cases describing their clinical features. METHODS: We investigated 6 apparently unrelated dentatorubral-pallidoluysian atrophy families comprising a total of 51 affected individuals: 13 patients were clinically examined, and for 38 patients clinical data were collected from clinical sources. The dentatorubral-pallidoluysian atrophy diagnosis was genetically confirmed in 18 patients. Genealogical data from historical archives were ana…
Effects of the flavonol quercetin and α-linolenic acid on n-3 PUFA status in metabolically healthy men and women: a randomised, double-blinded, place…
2017
AbstractIncreased dietary intake and tissue status of the long-chainn-3 PUFA, EPA and DHA, is associated with cardiovascular benefits. Epidemiological and animal studies suggest that concomitant nutritive intake of flavonoids may increase the conversion ofα-linolenic acid (ALA) to longer-chainn-3 fatty acids EPA and DHA. We investigated the effects of increased ALA intake on fatty acid composition of serum phospholipids and erythrocytes in metabolically healthy men and women and whether fatty acid profiles and ALA conversion were affected by regular quercetin intake or sex. Subjects (n74) were randomised to receive at least 3·3 g/d ALA with either 190 mg/d quercetin (ALA+quercetin) or place…
