Histopathological findings of biopsied peripheral nerve and muscle were studied in a case with myxoedematous polyneuropathy. The most striking findings in the sural nerve were segmental demyelination and onion bulb formation with scanty mucinous deposits in addition to marked loss of large myelinated nerve fibres. The peroneus brevis muscle revealed the association of neuropathic and myopathic ...

Hydroxyapatite deposition disease (HADD), a disease most commonly found in middleaged individuals, is characterized by deposition of calcium phosphate crystals in periarticular tissues. The deposits frequently occur in tendons near their osseous attachments, most commonly involving the supraspinatus tendon. The etiology of HADD is unclear, but may be related to repetitive trauma or metabolic di...

Possible springs and their deposits are important targets for Martian exploration because of the information they contain about Martian landscapes and processes, provide indications for conditions in the Martian hydrosphere, are potential habitats for past (and present) Martian organisms, and their resource potential for human missions. The Dalhousie Mound Spring Complex (DMC) is one of largest...

seismic piezocone device (scptu) together with resonant column and cyclic triaxial test apparatus are employed to measure small strain shear modulus (g0) of carbonate sandy and clayey soils of southern coasts of iran. a large area of southern regions of iran is formed from clay, silt and sand. in this study, maximum shear modulus that is derived from both field (by seismic piezocone) and labora...

Introduction: Exposures of layered materials on Mars are of significant interest because of their potential for yielding information on past geologic processes and environments [1-12]. Arabia Terra, an extensive region of cratered ancient highlands, has an abundance of light-toned layered deposits that are both intracrater and intercrater in nature [6,7]. Analysis of the western and southwester...

Tertiary meteoric hydrothermal systems have altered the rocks exposed over more than S% of the land surface of the northwestern United States and southern British Columbia, including at least 25,000 1m? in Idaho. The systems typically involved convective circulation of fluid derived from ordinary meteoric groundwater& around crystallizing, calc-alksline, epizonal plutons eiiiP.laced into coeval...

The size frequency distributions of beta-amyloid (A beta) and prion protein (PrPsc) deposits were studied in Alzheimer's disease (AD) and the variant form of Creutzfeldt-Jakob disease (vCJD) respectively. All size distributions were unimodal and positively skewed. A beta deposits reached a greater maximum size and their distributions were significantly less skewed than the PrPsc deposits. All d...

The abundant documentation of small mammals in the Italian peninsula, collected over recent years, furnishes a detailed biochronological sequence mainly from the Late Pliocene onwards. An updated stratigraphic framework is here presented, based on the European small mammal biozonation. The Early Villanyian is characterized by Mimomys hassiacus, M. stehlini, and, later, poorly documented M. polo...
