Intermittent faults (IFs) are difficult to diagnose and may cause a great disruption in industrial processes. Most IFs are related to gradual degradation of components or systems. For instance, evolution of connection failures is shown in Fig. 1 (Correcher et al., 2004), (Sorensen et al, 1998). Connection failures are rarely repaired so its behaviour worsens over time. Intermittent faults behav...
Accurate and sensitive detection of bladder cancer is critical to diagnose this deadly disease at an early stage, estimate prognosis, predict response to treatment, and monitor recurrence. In past years, laboratory diagnosis and surveillance of urinary bladder cancer have improved significantly. Although urine cytology remains the gold standard test, many new urinary biomarkers have been identi...
Extrahepatic cholangiocarcinoma is often clinically challenging to diagnose. Even multidisciplinary approaches which include computed tomography, magnetic resonance imaging, and endoscopic retrograde cholangiography are unsatisfactory in some cases, especially with biliary stricture. Percutaneous transhepatic cholangioscopy (PTCS) with its direct visualization for biopsy appears to be a promisi...
The solitary pulmonary nodule is a common lesion that has multiple benign and malignant causes and when detected often creates a diagnostic challenge. Such a challenge is framed on one side by the need to detect and diagnose lung cancer or other malignancies at an early manageable stage and on the other side by the need to restrain from unnecessary intervention on benign lesions. The article wi...
Hydatid disease, caused by larval stage of parasite echinococcus, is considerable health problem world wide. Hydatid cyst of infratemporal region is extremely rare, even in endemic areas. A 35 year old woman presented with slowly progressive swelling in infratemporal region. At operation the cystic mass was demonstrated and histopathologic examination confirmed the diagnosis of hydatid cyst. A ...
In recent years, development of highly sensitive biosensors is the main purpose of researchers to diagnose and prevent diseases. Accordingly, in this paper, surface plasmon resonance (SPR) biosensor has been designed based on one dimensional layered structures. With regard to the fact that the quality of SPR sensors strongly depends on the reflectance amplitude and full width at half maximum (F...
Background and Aim: Diagnosis of occlusal caries in early stages is more difficult than other types, and needs practical proficiency and accuracy as well as application of advanced and modern equipments. The aim of this study was to evaluate the variations among dentists in diagnosis of occlusal caries. Materials and Methods: In this descriptive cross-sectional study, 6 permanent first molar ...
Systemic sclerosis (SSc) is characterized by immunological disturbances, vascular damage and overproduction of extracellular matrix by stimulated fibroblasts. It has been postulated that immunological reactions involved in the pathogenesis of SSc may promote the development of malignancies. Coexistence of this disease with neoplasmatic processes is relatively frequent. In our report we describe...
Testis lymphoma (diffuse large B cell lymphoma) metastasized to the gallbladder. The gall bladder is rarely involved in cases of the malignant lymphoma, and lymphoma metastasis from the testis to the gallbladder has not been previously reported. These reports may possibly change by the introduction of PET/CT. Furthermore, although it was a struggle to diagnose this particular case, there is a p...
