Large Dose D-vitamin Treatment in COVID-19 Disease
2022
Autors: Sampsa Ilmari Kaukua, BA, RN-BSN Darba vadītājs: Valdis Pīrāgs MD, PhD, LUMF Pamatojums: D vitamīns ir nepieciešams dažādiem mērķiem, ne tikai kalcija un fosfora vielmaiņas regulēšanai un kaulu veselības uzturēšanai. Sirds un asinsvadu slimības, vēzis, elpceļu infekcijas un astma ir saistītas ar D vitamīna deficītu. D vitamīna deficīts skar visu vecumu cilvēkus. Saskaņā ar nesen publicētajiem pētījumiem pacientiem ar Covid-19 bija ievērojami zemāks 25(OH)D līmenis nekā pacientiem bez vīrusa. Mērķi: Veikt visaptverošu literatūras apskatu par esošajiem datiem par Covid-19, D vitamīna terapiju, CRP un feritīnu. Analizēt Latvijā veiktā Covid-19 lielo devu D vitamīna ārstēšanas pētījuma …
Genitourinary Symptoms—Patient Help-Seeking and General Practitioner Management: An Outpatient Based Survey at a Tertiary Hospital in Southern Italy
2015
Abstract Introduction General knowledge of most common genitourinary diseases is often lacking. In this survey we evaluated the attention given by patients and general practitioners to genitourinary symptoms, and particularly to hematuria and potential early signs of genitourinary cancer. Methods A structured self-administered questionnaire was administered to outpatients before the urological consultation. The questionnaire consisted of 4 multiple choice questions to record the level of patient awareness of urological symptoms, the importance given to gross hematuria, the interval between the onset and the visit, the regularity of physical examination and the first-level investigations ind…
Rat hepatocytes in primary culture synthesize and secrete cellular fibronectin
1992
Fibronectins, involved in cell-matrix interactions and cell attachment, are glycoproteins which show a remarkable heterogeneity, due to alternative splicing. The type III-related domains, ED-A and ED-B, are present in cellular fibronectin in a variety of ratios whereas they are absent in circulating plasma fibronectin. Fibronectin synthesis by hepatocytes which are accepted as suppliers of plasma fibronectin was studied in primary cultures during a 6-day culture period. Using site-specific antibodies we demonstrate that rat hepatocytes are also able to synthesize and secrete fibronectin bearing the ED-A domain from Day 3 on after inoculation. By immunocytological characterization of the hep…
Agreement on the Choice of Non-applicable Law or Law not in Accordance with Article 22(1) of the Twin Regulations: what Consequences for the Couple’s…
2021
Los Reglamentos (UE) 2016/1103 y 2016/1104 del Consejo autorizan a las parejas transfronterizas a elegir la ley aplicable a sus relaciones patrimoniales sobre la base de uno de los criterios enumerados en el artículo 22.1. Sin embargo, el acuerdo de elección de la ley puede tener un contenido diferente al señalado en la redacción del artículo 22 de los ?Reglamentos Gemelos?. El objetivo del análisis es ilustrar que sería incorrecto sostener que tales acuerdos son, a priori, inválidos o no permiten la autonomía de la voluntad. Esta cuestión requiere una evaluación de la finalidad concreta del acuerdo de las partes y debería, al menos, estar abierta al examen del tribunal competente.
Conjunction of Conditional Events and t-Norms
2019
We study the relationship between a notion of conjunction among conditional events, introduced in recent papers, and the notion of Frank t-norm. By examining different cases, in the setting of coherence, we show each time that the conjunction coincides with a suitable Frank t-norm. In particular, the conjunction may coincide with the Product t-norm, the Minimum t-norm, and Lukasiewicz t-norm. We show by a counterexample, that the prevision assessments obtained by Lukasiewicz t-norm may be not coherent. Then, we give some conditions of coherence when using Lukasiewicz t-norm
La perception phonémique en français des apprenants polonophones (le cas des voyelles antérieures de moyenne aperture : [e][ɛ])
2017
The perception of sounds of a foreign tongue influences the quality of comprehension and speaking in the language, as well as learning how to read and write properly. The differentiation and identification of sounds enables the development of aural-verbal memory, subsequently associating particular sound patterns with particular meanings. In other words, a developed perception of sounds ensures an efficient communication in a foreign language. Since learners perceive foreign sounds with varied proficiency, the teacher should recognize the difficulties and undertake remedial measures to facilitate learning progress. This article aims to present an educational tool, currently in development, …
An infinite family of counterexamples to a conjecture on positivity
2021
Recently, G. Mason has produced a counterexample of order 128 to a conjecture in conformal field theory and tensor category theory in [Ma]. Here we easily produce an infinite family of counterexamples, the smallest of which has order 72.
Functional evidence for GABA as modulator of the contractility of the longitudinal muscle in mouse duodenum: Role of GABAA and GABAC receptors
2007
We investigated, in vitro, the effects of gamma-aminobutyric acid (GABA) on the spontaneous mechanical activity of the longitudinal smooth muscle in mouse duodenum. GABA induced an excitatory effect, consisting in an increase in the basal tone, which was antagonized by the GABA(A)-receptor antagonist, bicuculline, potentiated by (1,2,5,6-Tetrahydropyridin-4-yl)methylphosphinic acid hydrate (TPMPA), a GABA(C)-receptor antagonist and it was not affected by phaclofen, a GABA(B)-receptor antagonist. Muscimol, GABA(A) receptor agonist, induced a contractile effect markedly reduced by bicuculline, tetrodotoxin (TTX), hexamethonium and atropine. Cis-4-aminocrotonic acid (CACA), a specific GABA(C) …
Differential sensitivity of rat hepatocyte CYP isoforms to self-generated nitric oxide.
2001
AbstractEarly loss of P450 in rat hepatocyte cultures appears directly related to nitric oxide (NO) overproduction. This study investigates the influence of endogenously generated NO (or NO-derived species) on the relative expression of cytochrome P450 (CYP) isoforms in rat hepatocytes. Our results support the view that loss of P450 holoenzyme in culture is the ultimate consequence of a NO driven process, activated during the common hepatocyte isolation procedure, that leads to an accelerated and selective degradation of specific CYP apoproteins. Under conditions in which NO and peroxynitrite formation is operative, changes in the level of specific CYP isoforms result in a significant alter…
LATE-BREAKING ABSTRACT: MUC1 downregulation induces corticosteroid resistance in asthma'sin vitroandin vivomodels
2016
Background: Corticosteroids are in the first-line of Asthma treatment. However a subset of asthmatic patients is insensitive to anti-inflammatory effects of corticosteroids. Our previous data demonstrated that MUC1 downregulation correlates corticosteroid resistance in Nasal Polyposis and COPD. We hypothesized that MUC1 is also involved in corticosteroid resistance in Asthma. Objective: To analyze the role of MUC1 in the corticosteroid effectiveness in Asthma9s in vitro and in vivo models. Methods: 20 patients with steroid resistant Asthma were recruited. The expression of MUC1 was determined by real-time PCR in inflammatory cells from peripheral blood. HMVEC-L and U937 cells knockdown with…
