Assisted reproductive technologies (ART) have been associated with several adverse perinatal outcomes involving placentation and fetal growth. It is critical to examine each intervention individually in order to assess its relationship to the described adverse perinatal outcomes. One intervention ubiquitously

The pathologic features of adult-onset leukoencephalopathy/leukodystrophy with axonal spheroids (ALAS) are variable, and this has led to different hypotheses as to whether primarily demyelination or axonopathy may underlie this disorder. Typical ALAS pathology is rarely accompanied by focal multiple sclerosis

Macroporous scaffolds composed of chitosan and using oxidized dextran as a crosslinker are produced through cryogelation. Introducing gelatin as a third component into the structure results in the formation of mesopores in the pore walls, which are not seen if
