LIGAMENTOUS INSTABILITY OF THE FIRST RAY: A CASE REPORT INTRODUCING THE NAVICULOCUNEIFORM KISSING SIGN ON MRI SCAN

Ligamentous instability of the first ray: A case report introducing the naviculocuneiform kissing sign on MRI scan

Acute instability of the first ray following trauma is a rare type of Lisfranc injury.Plain radiographs may demonstrate instability if Handbag there is a clear dislocation of the first ray, however subtle injuries are difficult to recognise.Magnetic resonance imaging (MRI) has been described in the literature as an adjunct in the diagnosis of subtl

Survey of cyclopids (Crustacea, Copepoda) in Brazil and preliminary screening of their potential as dengue vector predators

INTRODUCTION: Cyclopid copepods are known to be good mosquito controllers, specially as regards the larvae of the dengue vectors Aedes aegypti and Ae.albopictus.MATERIAL AND Service METHOD: The objective of the study was to survey the local copepod fauna and search for new strains of M.longisetus var.longisetus, comparing the potential of the sampl

A general theory of glacier surges

We present the first general theory of glacier surging that includes both temperate and polythermal glacier surges, based on coupled mass and enthalpy budgets.Enthalpy (in the form of thermal energy and water) is gained at the glacier bed from geothermal heating plus frictional heating (expenditure of potential energy) as a consequence of ice flow.
