The Trout Valley Formation of Emsian–Eifelian age in northern Maine hosts evidence of early vascular plant communities interpreted as having colonized wetland, estuarine environments. To date, collections made under permits issued by the Baxter State Park Commission, originate from outcrop along Trout Brook, its tributaries, and poorly exposed lithologies inside the woodlands. Construction of a...

OBJECTIVES To find out if conventional and automatic needle EMG of the tongue can be helpful in the diagnosis and differentiation of limb and bulbar onset amyotrophic lateral sclerosis. METHODS Motor unit action potential (MUAP) analysis and peak ratio interference pattern analysis were performed in the right genioglossus muscle of 30 healthy subjects aged 30-81 years, 10 patients aged 49-73 ...

Balo's concentric sclerosis (BCS) is a variant of multiple sclerosis (MS). It may present as a lesior clinically and radiologically indistinguishable from brain tumour particularly on computerized tomography (CT) scans. Diagnosis only gets clear when magnetic resonance imaging and spectroscopy (MRI & MRS) and brain biopsy is done. We report a case of 30 year old male with progressive headache a...

Baló’s concentric sclerosis (BCS) is an atypical variant of multiple sclerosis (MS) characterized by remarkable concentric demyelination patterns in the white matter of the brain and in the spinal chord. In Khonsari and Calvez (2006), we introduced a very simple model based on cellular self-organization, which reproduced quite accurately the quantitative and qualitative aspects of this disease....

In 1928, Baló described a law student with an unusual fatal illness marked by aphasia and a right hemiplegia, with later optic neuritis and normal cerebrospinal fluid. At autopsy, he found a disease of the white matter characterised by foci varying in size from a lentil to that of a pigeon's egg and presenting gray softening and, in part, concentricity, where the medullary sheaths were destroye...
