The aim of this study is to develop an automatic computer method to discriminate asymptomatic from knee osteoarthritis pathological gait patterns using ground reaction forces. We investigate a discriminant feature of kinetic data based on wavelets. Classification is based on the nearest neighbor classifier. Experiments were conducted using data of 43 cases, 16 asymptomatic and 27 pathological. ...

The clinical and pathological features of a case of abetalipoproteinaemia in a 38-year-old patient are described in detail. A feature not previously recorded was a marked reduction in the velocity of ocular horizontal saccadic movements. Pathological studies revealed an active chronic demyelinating process. The patient showed no response to large doses of vitamin E. The rationale for this thera...

hyperspectral sensors provide a large number of spectral bands. this massive and complex data structure of hyperspectral images presents a challenge to traditional data processing techniques. therefore, reducing the dimensionality of hyperspectral images without losing important information is a very important issue for the remote sensing community. we propose to use overlap-based feature weigh...

Clinical and pathological data from eight cases of acute haemorrhagic leucoencephalitis (AHL) confirm the previously documented devastating features of this disease. Data from 30 cases of perivenous encephalitis (PVE) associated with viral diseases reveal pathological changes ranging from lymphocytic cuffing of vessels to severe vasculitis similar to the vasculitis of AHL. Relatively few cases ...

This paper focuses on a robust feature extraction algorithm for automatic classification of pathological and normal voices in noisy environments. The proposed algorithm is based on human auditory processing and the nonlinear Teager-Kaiser energy operator. The robust features which labeled Teager Energy Cepstrum Coefficients (TECCs) are computed in three steps. Firstly, each speech signal frame ...

introduction: breast cancer is the most common of all malignant neoplasms in women worldwide. this study aims to demonstrate certain biological, clinical and pathological characteristics of patients treated at the university hospital oncology unit. methods: a descriptive study was conducted during a period of 2 years, from october 2003 through september of 2005 in kermanshah, iran. 555 patients...

following experimental inoculation of 3-week-old turkeys with different titres (106, 104, 103, 102 and 101 egg infectious dose (eid50)) of a/ostrich/italy/984/2000 h7n1 highly pathogenic avian influenza virus (hpaiv), the selected tissues and organs were examined for pathological changes. tissue samples from different organs that obtained from dead and sacrificed birds were fixed in 10% neutral...

we studied the hepatotoxic effects of a deltamethrin containing formulation (decis®) on developing em-bryo of gallus domesticus. fertilized eggs were immersed in three different concentrations of deltamethrin (12.5, 25 and 50 mg/l) for 60 min at 37 ˚c prior to incubation (ed 0) and on the 4th day of incubation (ed 4) and incubated till embryonic day (ed) 16. exposure to 50 mg/l of deltamethrin ...

background: behçet’s disease (bd) is a multisystemic inflammatory vasculitis of unknown etiology, and vasculitis being its major pathological feature. objectives: we studied the prevalence of microembolic signals (mes) in patients with diagnosis behçet's disease. we also tried to determine the frequency of mes in bd patients with or without neurological involvement. materials and methods: ...

Introduction: Cloacal malformation is an extremely rare fetal pathological condition but an important anomaly that presents as a variety of defects. It predominantly affects females, with prevalence of 1 in 50,000 births. Prenatal ultrasonography usually showed oligohydramnios and the fetus having a large cystic mass in the lower abdomen with a single septum, bilateral hydronephrosis, ambig...
