The effects of the duration of the floods on abiotic variables and attributes of species tolerant and intolerant to hypoxia (STH and SIH respectively) were evaluated in rivers and lakes of the upper Paraná River. Fish were sampled once a year, in six sampling stations, during the high water period from 2000 to 2003. There were overall reductions in dissolved oxygen levels and increases in trans...

A Grey parrot (Psittacus erithacus) had previously been taught to use English count words ("one" through "sih" [six]) to label sets of one to six individual items (Pepperberg, 1994). He had also been taught to use the same count words to label the Arabic numerals 1 through 6. Without training, he inferred the relationship between the Arabic numerals and the sets of objects (Pepperberg, 2006b). ...

High dose steroids (HDS) are used in the treatment of haematological malignancies. The reported risk of steroid-induced diabetes (SID) is high. However, screening is not consistently performed. We implemented a protocol for detection and management of SID and steroid-induced hyperglycamia (SIH) in haematology outpatients receiving HDS. Eighty-three people were diagnosed with a lymphoproliferati...

Incorporation mechanisms of H2 in silica glass were studied with Raman and infrared (IR) microspectroscopy. Hydrogenated samples were prepared at temperatures between 800°C and 955°C at 2 kbar total pressure. Hydrogen fugacities (fH2) were controlled using the double capsule technique with the iron–wüstite (IW) buffer assemblage generating fH2 of 1290–1370 bars corresponding to H2 partial press...

The performance of an inertial navigation system (INS) operated on a moving base greatly depends on the accuracy of rapid transfer alignment (RTA). However, in practice, the coexistence of large initial attitude errors and uncertain observation noise statistics poses a great challenge for the estimation accuracy of misalignment angles. This study aims to develop a novel robust nonlinear filter,...

Across the animal kingdom, individuals of the same species differ in their propensity to take risks, explore new environments, and to be active, aggressive or sociable; these behaviours are often correlated across individuals. Behaviours showing inter-individual variation but are consistent within individuals through time and across contexts are coined ‘personality’. When different personality ...

PURPOSE The detection and localization of cerebrospinal fluid (CSF) leakage in patients with spontaneous intracranial hypotension (SIH) is important. The aim of this study was to evaluate the usefulness of multidetector CT (MDCT)-myelography in patients with SIH. METHODS A radiologist retrospectively searched the electronic database to find the patients who had undergone MDCT-myelography for ...

The current mainstay of treatment in spontaneous intracranial hypotension (SIH) is an epidural blood patch (EBP). Although magnetic resonance imaging (MRI) has a well-established role in the diagnosis of SIH, imaging features regarding the treatment efficacy of EBP have rarely been discussed. We therefore sought to investigate and compare the sequential brain MRI studies before and after EBP by...

BACKGROUND Spontaneous intracranial hypotension (SIH) is a clinically variable syndrome caused by low cerebrospinal fluid (CSF) pressure due to a non-traumatic CSF leak. PHENOMENOLOGY SHOWN This case describes a 68-year-old gentleman who presents with chronic and slightly progressive kinetic tremor of bilateral hands associated with gait ataxia and gait start hesitation. EDUCATIONAL VALUE T...
