Do proctored online University exams in Covid-19 era affect final grades respect face-to-face exams?
2021
The Covid-19 pandemic forced universities to convert their traditional face-to-face exams to online exams with doubts as to whether student cheating or technical difficulties would affect their final grades. After taking three of these exams online, we considered comparing their grades with those of previous years on traditional exams. The average mark of the traditional exams before the pandemic was 6.95 over 10, while the average mark of the three exams carried out in the Covid-19 era is 6.64. The student's t test indicated that there are no significant differences between the two types of exams in the mean (p = 0.408), the median (p = 0.378), the range (p = 0.307), the minimum (p = 0.410…

Neurocysticercosis with a single brain lesion in Germany: a case report
2009
Neurocysticercosis is rare in Western Europe and a high degree of physician awareness is necessary for diagnosis. We describe a case of Neurocysticercosis with a single brain lesion acquired in Germany in which only surgical removal and subsequent histological examination allowed diagnosis whereas diagnostic investigation yielded no pathological findings.
Roman wood sculptures from Burgundy
2013
For the first time, the corpus of Roman wood sculptures from Burgundy is gathered together in a catalogue, with added photographic documents and bibliography. The twenty-five sculptures are listed and studied from a stylistic, iconographic and technical point of view. In the XIIth century, an actual school of monastic wood sculpture seemed to develop within the boundaries of the duchy of Burgundy, bringing a great diversity as far as formal and technical contributions are concerned. The sculptures that are the most representative to help the understanding of those numerous contributions are thoroughly studied. Their stylistic relationships with manuscripts dating back from the Carolingian R…
Caged Dexamethasone/Quercetin Nanoparticles, Formed of the Morphogenetic Active Inorganic Polyphosphate, are Strong Inducers of MUC5AC
2021
Inorganic polyphosphate (polyP) is a widely distributed polymer found from bacteria to animals, including marine species. This polymer exhibits morphogenetic as well as antiviral activity and releases metabolic energy after enzymatic hydrolysis also in human cells. In the pathogenesis of the coronavirus disease 2019 (COVID-19), the platelets are at the frontline of this syndrome. Platelets release a set of molecules, among them polyP. In addition, the production of airway mucus, the first line of body defense, is impaired in those patients. Therefore, in this study, amorphous nanoparticles of the magnesium salt of polyP (Mg-polyP-NP), matching the size of the coronavirus SARS-CoV-2, were pr…
Anthropometric and pharmacotherapeutic variables on acute emesis induced by cisplatin-containing chemotherapy.
2000
OBJECTIVE: To characterize the effects of anthropometric and pharmacotherapeutic variables on acute emesis induced by cisplatin-containing regimens with dosages ·50 mg·m−2. METHODS: A prospective, cross-sectional, noncontrolled study was performed to analyze acute vomiting during the first 24 hours in patients treated in a Spanish hospital. The patients received an intravenous combination of drugs (2 doses of metoclopramide 3 mg/kg, dexamethasone 20 mg) as first-choice antiemetic therapy. Intravenous ondansetron 8 mg and dexamethasone 20 mg served as an alternative regimen in patients <30 years old with a history of extrapyramidal manifestations or emesis in previous cycles. Therapeutic …
Suppression of inflammation by low-dose methotrexate is mediated by adenosine A2A receptor but not A3 receptor activation in thioglycollate-induced p…
2005
Prior studies demonstrate that adenosine, acting at one or more of its receptors, mediates the anti-inflammatory effects of methotrexate in animal models of both acute and chronic inflammation. Both adenosine A2A and A3 receptors contribute to the anti-inflammatory effects of methotrexate treatment in the air pouch model of inflammation, and the regulation of inflammation by these two receptors differs at the cellular level. Because different factors may regulate inflammation at different sites we examined the effect of low-dose weekly methotrexate treatment (0.75 mg/kg/week) in a model of acute peritoneal inflammation in adenosine A2A receptor knockout mice and A3 receptor knockout mice an…
Microscopic Study of Injectable Steroids: Effects of Postmixing Time on Particle Aggregation
2020
Background: Epidural steroid injection (ESI) is a common practice for pain treatment since 1953. In 2014, the FDA issued a warning about ESI. Studies have focused on the effect of the particle size and their ability to generate harmful aggregates. Although steroid aggregates provide longer times for reabsorption, therefore a longer anti-inflammatory effect, they are potentially harmful to the central nervous system via embolic mechanisms. Previous studies have established that steroidal aggregates with asizes over 100 μm are potentially able to occlude blood vessels. Studies by Tiso et al and Benzon et al addressed the role of steroids on CNS adverse events, with similar outcomes. The main …
Smart cities: Case studies
2016
Il capitolo mostra alcuni esempi di smart cities. Nel capitolo i casi di studio sono divisi in aree geografiche, che a livello macroscopico si riferiscono a diversi tipi di città e comunità in relazione a diversi livelli di innovazione tecnologica e tipo di capitale umano, che sono fattori chiave per raggiungere uno sviluppo smart. Le città di nuova costruzione sono città appartenenti all'area asiatica pianificate da zero per limitare emissioni nocive ed alzare la qualità della vita dei cittadini. Nel paragrafo sulle città del Nord Europa e quelle del Mediterraneo sono descritte città che possiedono alte caratteristiche storiche. Talvolta queste hanno poche possibilità - per le loro caratte…
Tryptophan quenching as linear sensor for oxygen binding of arthropod hemocyanins.
2008
Oxygen binding of hemocyanins results in an absorption band around 340nm and a strong quenching of the intrinsic tryptophan fluorescence. Our study analyses in detail the fluorescence quenching within two hemocyanins, a hexamer (Panulirus interruptus) and a 4 x 6-mer (Eurypelma californicum). Based on the comparison of calculated and measured transfer efficiencies we could show that: (1) For both hemocyanins FRET (fluorescence resonance energy transfer) is exclusively responsible for quenching of the tryptophan fluorescence upon oxygen binding. (2) Tryptophan quenching by FRET is independent of the oxy- or deoxy conformation of the protein. (3) The quenching takes place at the subunit level…
