this study examined the effects of aural and written prompts under two planning conditions (i.e. pre-task planning and no planning) on complexity, accuracy, and fluency of test takers' writing production. forty learners in an english institute, who had already been classified as intermediate according to the oxford placement test, were assigned to two planning conditions (i.e. no planning and p...

As Rosenberg (1972) pointed out in Katz's Handbook of Clinical Audiology. the first, and possibly the most valuable, test of all is the case history. In the practice of aural medicine, questionnaires can be of considerable value, as in medicine in general (Bennett and Ritchie, 1975). In aural medicine, questionnaires may be particularly valuable for the assessment of the disability and handicap...

Phosphate is essential for all major life processes, especially energy metabolism and signal transduction. A linear phosphate polymer, polyphosphate (polyP), linked by high-energy phosphoanhydride bonds, can interact with various proteins, playing important roles as an energy source and regulatory factor. However, polyP-binding structures are largely unknown. Here we proposed a putative polyP b...

We present a silica nanoparticle (SNP) functionalized with polyphosphate (polyP) that accelerates the natural clotting process of the body. SNPs initiate the contact pathway of the blood-clotting system; short-chain polyP accelerates the common pathway by the rapid formation of thrombin, which enhances the overall blood-clotting system, both by accelerating fibrin generation and by facilitating...

Inorganic polyphosphate (polyP) is a biopolymer of phosphoanhydride-linked orthophosphate residues. PolyP is involved in multiple cellular processes including mitochondrial metabolism and cell death. We used artificial membranes and isolated mitochondria to investigate the role of the polyP in mitochondrial ion transport and in activation of PTP. Here, we found that polyP can modify ion permeab...

Acute mastoiditis in the newborn is a very rare disease. Herein we report a case of a 28-day-old child with right aural atresia and ipsilateral mastoiditis requiring mastoidectomy. To our knowledge, this is the youngest case reported in the literature. Issues on diagnosis and management of mastoiditis in cases of aural atresia are further discussed. Based on our experience and on previous repor...

Activated platelets secrete a negatively charged polymer, polyphosphate (polyP). Here, we explore the interactions of polyP with fibrin(ogen) and its effect on fibrin structure and fibrinolysis. Electrophoretic mobility and binding assays indicate that polyP interacts with fibrinogen and soluble fibrin. Clots formed in the presence of polyP exhibited reduced turbidity and permeability indicativ...

INTRODUCTION AND OBJECTIVES Benign lesions of the external auditory canal (EAC) are an infrequent cause of temporal bone CT scan requests. We are not usually well versed in the different pathologies located in the EAC, perhaps because it is "only" a conduit and the relevant anatomical structures are located in the middle and inner ear. Our objective was to improve knowledge of this structure by...
