Clinical implications of serum neurofilament in newly diagnosed MS patients: a longitudinal multicentre cohort study

2020

Abstract Background We aim to evaluate serum neurofilament light chain (sNfL), indicating neuroaxonal damage, as a biomarker at diagnosis in a large cohort of early multiple sclerosis (MS) patients. Methods In a multicentre prospective longitudinal observational cohort, patients with newly diagnosed relapsing-remitting MS (RRMS) or clinically isolated syndrome (CIS) were recruited between August 2010 and November 2015 in 22 centers. Clinical parameters, MRI, and sNfL levels (measured by single molecule array) were assessed at baseline and up to four-year follow-up. Findings Of 814 patients, 54.7% (445) were diagnosed with RRMS and 45.3% (369) with CIS when applying 2010 McDonald criteria (R…

Cognitive impairment in multiple sclerosis can be predicted by imaging early in the disease.

2008

Background: Cognitive impairment is common in multiple sclerosis (MS) and adds significantly to the burden of the disease. The ability to predict future cognitive impairment from imaging obtained at disease onset has not been investigated. Methods: 62 patients imaged within 3 months of a clinically isolated syndrome were assessed neuropsychologically 7 years later. Baseline and periodic MRI measures of lesions, atrophy and normal-appearing white and grey matter were regressed against neuropsychological scores to explore the best predictors of cognitive outcome. Results: 28 patients had developed clinically definite MS at follow-up and a further nine met revised McDonald criteria for MS. Def…

The impact of isolated lesions on white-matter fiber tracts in multiple sclerosis patients

2015

Infratentorial lesions have been assigned an equivalent weighting to supratentorial plaques in the new McDonald criteria for diagnosing multiple sclerosis. Moreover, their presence has been shown to have prognostic value for disability. However, their spatial distribution and impact on network damage is not well understood. As a preliminary step in this study, we mapped the overall infratentorial lesion pattern in relapsing–remitting multiple sclerosis patients (N = 317) using MRI, finding the pons (lesion density, 14.25/cm3) and peduncles (13.38/cm3) to be predilection sites for infratentorial lesions. Based on these results, 118 fiber bundles from 15 healthy controls and a subgroup of 23 …

Polynomials generated by linear operators

2004

We study the class of Banach algebra-valued n n -homogeneous polynomials generated by the n t h n^{th} powers of linear operators. We compare it with the finite type polynomials. We introduce a topology w E F w_{EF} on E , E, similar to the weak topology, to clarify the features of these polynomials.

An approximate Rolle's theorem for polynomials of degree four in a Hilbert space

2005

We show that the fourth degree polynomials that satisfy Rolle’s Theorem in the unit ball of a real Hilbert space are dense in the space of polynomials that vanish in the unit sphere. As a consequence, we obtain a sort of approximate Rolle’s Theorem for those polynomials.

Factorization of absolutely continuous polynomials

2013

In this paper we study the ideal of dominated (p,s)-continuous polynomials, that extend the nowadays well known ideal of p-dominated polynomials to the more general setting of the interpolated ideals of polynomials. We give the polynomial version of Pietsch s factorization Theorem for this new ideal. Our factorization theorem requires new techniques inspired in the theory of Banach lattices.

Baraka Obamas un Donalda Trampa prezidenta kandidatūras maiņas ietekme uz startautisko akciju tirgu

2021

Bakalaura darba tēma – “Baraka Obamas un Donalda Trampa prezidenta kandidatūras maiņas ietekme uz starptautisko akciju tirgu”. Darbs ir izstrādāts ar mērķi apzināt kā prezidentu maiņa ASV ietekmē starptautisko akciju tirgu, apskatīt ietekmējošos faktorus, kā arī analizēt un salīdzināt Baraka Obamas un Donalda Trampa ietekmi uz akciju tirgu. Donalds Tramps ir bijis viens no skaļākajiem un apspriestākajiem ASV prezidentiem pēdējo gadu laikā tādēļ arī darba autors izvēlējās sīkāk izpētīt šī personāža sasniegumus un darbības atsaucoties tieši uz akciju tirgus cenu izmaiņām salīdznot datus ar Donalda Trampa prezidenta amata priekšteci Baraku Obamu, kurš tāpat kā Džo Baidens pārstāv Demokrātu par…

Politiķu priekšvēlēšanu kampaņas solījumu pildīšana: Donalda Trampa gadījums

2021

Darbs ir balstīts uz politiķu priekšvēlēšanas kampaņu programmām un tiek pētīts, kā politiķi pilda un pieturas savai priekšvēlēšanas kampaņas programmai, kas tiek izskatīts uz bijušā ASV Valsts prezidenta – Donalda Trampa piemēra. Darba mērķis ir izanalizēt Donalda Trampa 2015. gada priekšvēlēšanas kampaņas programmas saturu, atlasīt 5 galvenos programmas punktus un noskaidrot – vai tie tika izpildīti, vai nē, un tādā gadījumā, noskaidrot kādi bija iemesli neveiksmei. Teorētiskajā daļā tiek analizēta ASV federālā sistēma un tās ietekme uz ASV Valsts prezidenta rīcības iespējām, kā arī, priekšvēlēšanas kampaņas mērķis. Darbā tiek pielietota kvalitatīvā izpētes metode, kas paredz Donalda Tram…
