Genetic burden in multiple sclerosis families

2013

A previous study using cumulative genetic risk estimations in multiple sclerosis (MS) successfully tracked the aggregation of susceptibility variants in multi-case and single-case families. It used a limited description of susceptibility loci available at the time (17 loci). Even though the full roster of MS risk genes remains unavailable, we estimated the genetic burden in MS families and assess its disease predictive power using up to 64 single-nucleotide polymorphism (SNP) markers according to the most recent literature. A total of 708 controls, 3251 MS patients and their relatives, as well as 117 twin pairs were genotyped. We validated the increased aggregation of genetic burden in mult…

Effect of the serum from multiple sclerosis patients on an in vitro model of blood-brain barrier.

2008

Multiple sclerosis (MS) is characterized by focal inflammatory demyelination, largely due to autoimmune responses against different components of the myelin sheet. It is also generally accepted that the pathogenesis of MS consists of inflammatory and neurodegenerative phases, where demyelination should produce partially reversible clinical deficits that can remit, due to limited remyelination, while axonal degeneration produces permanent non-remitting clinical damage. It is also assumed that nervous system inflammation is initiated by autoreactive, myelin-specific T cells that permeate the blood-brain barrier and trigger a series of events leading to tissue destruction. In addition to antib…

Sense of Coherence and Health-Related Quality of Life in Patients with Multiple Sclerosis: The Role of Physical and Neurological Disability

2022

Multiple sclerosis is a progressive demyelinating disease of the central nervous system that can lead to permanent disability and significantly impact the quality of life. The present study explores the relationship between neurological disability and disease symptoms, quality of life, and the level of sense of coherence, which is an important resource for coping with the disease. EDSS, GNDS, SOC-29, and MSIS-29 were used in the presented study. The study group consisted of 137 people diagnosed with multiple sclerosis. The study showed the correlation between most of the analyzed variables. Mood disability and fatigue were significant predictors of the sense of coherence and explained 34% o…

(p,2)-equations resonant at any variational eigenvalue

2018

We consider nonlinear elliptic Dirichlet problems driven by the sum of a p-Laplacian and a Laplacian (a (p,2) -equation). The reaction term at ±∞ is resonant with respect to any variational eigenvalue of the p-Laplacian. We prove two multiplicity theorems for such equations.

Conceptualizing ecosystem tipping points within a physiological framework

2017

Connecting the nonlinear and often counterintuitive physiological effects of multiple environmental drivers to the emergent impacts on ecosystems is a fundamental challenge. Unfortunately, the disconnect between the way “stressors” (e.g., warming) is considered in organismal (physiological) and ecological (community) contexts continues to hamper progress. Environmental drivers typically elicit biphasic physiological responses, where performance declines at levels above and below some optimum. It is also well understood that species exhibit highly variable response surfaces to these changes so that the optimum level of any environmental driver can vary among interacting species. Thus, specie…
