Research ArticleOpen accessEvery word in the titleEimeria Legionensis and Eimeria kofoidi (Apicomplexa: Eimeriidae) Infection and Associated Lesions in Naturally Infected Red-Legged Partridges (Alectoris rufa)G. Fichi, G. Rossi, Stefania PerrucciWith the aim to identify the Eimeria species responsible for coccidiosis in 50 deceased red-legged partridges (Alectoris rufa), individual faecal samples were collected, dissolved in 2.5% K2Cr2O7 solution and maintained at room temperature to allow sporulation of the oocysts. Morphology and dimensions of sporulated oocysts were microscopically evaluated. To assess Eimeria intestinal localisation, faecal samples and scrapings taken from the … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 4 · 9 Nov 2017 · 7,689 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Mast Cell Distribution in Oral Lichen Planus and Lichenoid Lesions by Immunohistochemical and Histochemical AnalysisMahi Balci, Mustafa Emre ErcinThe histopathological assessment of Oral Lichen Planus (OLP) and oral lichenoid lesions is relatively subjective. The distinguishing criteria established by WHO effectively reproducible when all selection criteria were fulfilling but sometimes fail to provide a reliable diagnosis. The aim of the present study was to evaluate mast cell counts and their distribution among OLP and lichenoid lesions. The density and … …American Journal of Immunology, Vol. 12, Issue 4 · 11 Dec 2016 · 7,791 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAUTOMATIC SEGMENTATION OF SKIN LESIONS USING HISTOGRAM THRESHOLDINGNidhal Khdhair El Abbadi, Abbas Hussien MiryAutomatic lesion segmentation is an important part of computer-based image analysis of pigmented skin lesions. Currently, there is a great interest in the development of Computer-Aided Diagnosis (CAD) systems for dermoscopic images. The segmentation step is one of the most important ones, since its accuracy determines the eventual success or failure of a CAD system. This study introduced new method … …Journal of Computer Science, Vol. 10, Issue 4 · 19 Dec 2013 · 7,559 accessesView PDFCite
EditorialOpen accessEvery word in the titleAssociation between Infective Endocarditis and Premalignant Colorectal LesionsCarles FalcesThe association between Infective Endocarditis (IE) and Colorectal Cancer (CRC) has been known for more than 50 years. The microorganisms in which this association has been described are Streptococcus gallolyticus (formerly Streptococcus bovis) (Corredoira-Sánchez et al., 2012; Boleij et al., 2011), in different subspecies and, more recently, Enterococcus faecalis (Pericàs et al., 2016; 2017; Escolà-Vergé et al., 2020; Pericàs et … …American Journal of Infectious Diseases, Vol. 17, Issue 3 · 10 Jun 2021 · 11,559 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRelationship between Streptococcus gallolyticus Infective Endocarditis and Pre-Neoplastic Colorectal LesionsPau Vilardell, Sergio Moral, Josep Maria Frigola et al.Colorectal cancer is associated with Infective Endocarditis (IE) due to specific gut pathogens, such as Streptococcus gallolyticus subspecies, that use tumor presence as a point of blood entry. However, the association between Streptococcus gallolyticus related IE and pre-cancerous colorectal lesions like dysplastic adenomas is unclear. Seventy-one patients diagnosed with IE who underwent colonoscopy in the extension study during admission were … …American Journal of Infectious Diseases, Vol. 17, Issue 3 · 28 May 2021 · 7,131 accessesView PDFCite
HypothesisOpen accessEvery word in the titleIncreased Tissue Pressure Induces Demyelinated Lesions and Necroses in the BrainHelmut Barz, Ulrich Barz, Almut SchreiberA general brain edema increases the size of the brain tissue and stretches the elastic neuronal and glial fibers. Myelinated fibers are more elastic than unmyelinated fibers. The stretching of the neuronal fibers leads particular in regions of the white matter or areas surrounded by myelinated fiber tracts to an increased tissue pressure. This physical principle can be the reason … …Neuroscience International, Vol. 6, Issue 1 · 30 Mar 2015 · 7,424 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeature Extraction for Characterization of Breast Lesions in Ultrasound Echography and ElastographyShirley Selvan, M. Kavitha, S. Shenbagadevi, S. SureshProblem statement: Elastography is developed as a quantitative approach to imaging linear elastic properties of tissues to detect suspicious tumors. We propose an automatic feature extraction method in ultrasound elastography and echography for characterization of breast lesions. Approach: The proposed algorithm was tested on 40 pairs of biopsy proven ultrasound elastography and echography images of which 11 are cystic, 16 … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 8,315 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHistological Features and ki-67 Index In Cervical Atypical LesionsD. Cabibi, L. Giovannelli, M. Cacciatore et al.One of the most frequent challenges in routine diagnostic assessment of cervical biopsies consists of some lesions in which histological features of HPV infection are either inconsistently present or only mildly/focally evident. We named them Atypical Lesions (AL) because differential diagnosis with metaplastic/reactive lesions and LSIL is difficult. It would be important to identify among them those lesions that are … …American Journal of Infectious Diseases, Vol. 4, Issue 3 · 30 Sep 2008 · 7,231 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSorbitol-Induced Diabetic-Like Retinal Lesions in Rats: Microscopic StudyGaber A. RamadanThe present study investigated the sorbitol toxicity on the retinas of normal albino rats and founded by the light microscope that intra-peritoneal injection of Sorbitol (10-mg/kg-body weight per day) for 24 weeks produced similar diabetic like retinal lesions in these rats. The retinopathic effects of sorbitol injection affect retinal microvessels, pigment epithelium, neural retina and glial cells. Cytoplasmic vacuolation of … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 7,630 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePrevalence of Human Papillomavirus Types Among Mexican Women with Intraepithelial Lesions and Cervical Cancer: Detection with MY09/MY011 and GP5+/GP6+ Primer SystemsGloria Fernández-Tilapa, Berenice Illades-Aguiar, Dinorah Nashely Martínez-Carrillo et al.Squamous cervical carcinoma (SCC) is the most common cancer found in Mexican women. Human papillomavirus (HPV) infection is a prerequisite for this disease. In Mexico little is known about the prevalence of HPV-types and knowledge of the circulating genotypes by region is limited. The aim of this study was to determine the prevalence and genotypes of HPV in biopsies from … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,306 accessesView PDFCite
