Subventricular Zone Microstructure in Pediatric-Onset Multiple Sclerosis.

Objective: The aim of this study was to explore the microstructural dynamics of the subventricular zone (SVZ) with aging and their associations with clinical disability and brain structural damage in pediatric-onset multiple sclerosis (MS) patients.

Methods: One-hundred and forty-one pediatric-onset MS patients (67 pediatric and 74 adults with pediatric-onset) and 233 healthy controls (HC) underwent neurological and 3.0 T MRI assessment.

Determining the optimal gamma irradiation dose for developing novel cowpea () genotypes.

Purpose: Cowpea ( (L.) Walp.) is a major legume crops for human consumption and livestock feed in tropical regions.

Size-fractionated carbonaceous and iron-rich particulate matter in urban environments of France and Senegal.

Road traffic is one of the main sources of particulate matter in the urban environment, emitting particulate organic and elemental carbon compounds and metal-rich particles through combustion and brakes and tires wear. In Western Africa, the carbon and metal composition of airborne particles is also influenced by additional sources linked to biomass combustion and recent industrialization. Here, we investigated the impact of combustion-related and non-combustion-related emissions on the distribution of carbonaceous fractions and iron-rich particles in two urban environments in France and Senegal.

First records of and from Senegal (Selaginellaceae).

Background: The monogeneric family Selaginellaceae is made up of about 700 species distributed throughout the world, but the most concentrated part is in tropical and subtropical areas. According to the most recent infrageneric classification of the genus , six or seven subgenera can be recognised and perhaps 700 species. The genus is monophyletic, cosmopolitan, characterised by the presence of rhizophores, ligulated leaves and has a reniform adaxial sporangia with two type of spores (heterospory).

The root extracellular trap; a complex and dynamic biomatrix network essential for plant protection.

Plants have evolved a number of defense mechanisms to protect themselves against biotic stresses. Each cell, tissue, and organ is able to perceive and fight off attackers using a combination of chemical and physical defense mechanisms. Root cells employ similar defense response patterning.
