INTRODUCTION: Neural stem cells (NSC) are located essentially in the subventricular zone (SVZ), subgranular zone (SGZ), and along the central canal of the spinal cord. These cells can proliferate in vitro and differentiate into neurons, oligodendrocytes, and astroglia, thus contributing to repair in multiple sclerosis (MS). We conducted a pathological study to analyse neurogenic response in a patient with Marburg variant MS. METHODS: We present the case of a 27-year-old immunocompetent patient with Marburg variant MS, a fulminant form of the disease...

Celia Levesque
Diabetes mellitus is a common chronic disease affecting approximately 9% of the United States population. Successful management of diabetes demands constant self-management on the part of the patient. The patient has to balance diabetes medications, blood glucose monitoring, food intake, physical activity, and management of diabetes-related acute and chronic complications. The patient is often bombarded with misinformation from friends, relatives, and such sources as the Internet and social media. This article discusses the current recommendations for diabetes self-management education and skills including medical nutrition therapy, physical activity, smoking cessation, and assessment for diabetes distress...

Alzheimer's disease (AD) is a devastating neurodegenerative disorder characterized by pathological brain lesions and a decline in cognitive function. β-Amyloid peptides (Aβ), derived from proteolytic processing of amyloid precursor protein (APP), play a central role in AD pathogenesis. β-Site APP cleaving enzyme 1 (BACE1), the transmembrane aspartyl protease which initiates Aβ production, is axonally transported in neurons and accumulates in dystrophic neurites near cerebral amyloid deposits in AD. BACE1 is modified by S-palmitoylation at four juxtamembrane cysteine residues...

Bivalve mollusks are filter feeders and may accumulate human pathogens in their tissues. Many studies demonstrated human diseases associated with bivalve consumption, especially oysters. Anomalocardia brasiliana clams are distributed along the Brazilian coastal area and are an exotic ingredient for some typical dishes in Brazil. Even though there are several reports describing the contamination of oysters and mussels with human pathogens, there is a lack of studies reporting contamination of A. brasiliana with human pathogens...

Timely initiation of effective therapy is crucial for preventing disability in multiple sclerosis; however, treatment response varies greatly among patients. Comprehensive predictive models of individual treatment response are lacking. Our aims were: (i) to develop predictive algorithms for individual treatment response using demographic, clinical and paraclinical predictors in patients with multiple sclerosis; and (ii) to evaluate accuracy, and internal and external validity of these algorithms. This study evaluated 27 demographic, clinical and paraclinical predictors of individual response to seven disease-modifying therapies in MSBase, a large global cohort study...
