A rarely seen breast tumor: looking over the literature related to intracystic papillary carcinoma

Intracystic papillary carcinoma of the breast is a rarely seen tumor. It is often classified as a variant of in situ ductal carcinoma. Intracystic papillary carcinoma is slow growing and usually surrounded and limited by fibrosis capsule. Presently described is case of a 51-year-old postmenopausal patient. She felt a tumor in her left breast, and after examination, it was diagnosed as intracystic papillary carcinoma. Following adjuvant chemotherapy breast excision, and axillar dissection, patient was given curative external radiotherapy and hormonal treatment. As result of 40-month follow-up, the patient was evaluated as having local recurrence and no distant metastases. Follow-up and treatment protocols should be observed on case-by-case basi

Multibiometric identification by using ear, face, and thermal face

Abstract In this work, a secure multibiometric system is proposed. Three different biometric modalities which are ear, face, and thermal face are considered. The face and thermal face data were taken from USTC NVIE Spontaneous Database, whereas the ear data were collected from IIT Delhi Ear Image Database. For each modality, three feature extraction methods are used and four different classifiers (multilayer perceptron, decision tree, support vector machines, and probabilistic neural network) are trained by using two fusion methods which are matching score level and feature level fusion. According to the results, the individual biometrics are better for the identification problem. However, for the validation problem, both fusion methods give better false acceptance rate/false rejection rate values regarding to individual biometrics

Evaluation of Patients Presenting to the Pediatric Emergency Department with Carbon Monoxide Poisoning

Aim: Carbon monoxide poisoning is one of the significant causes of intoxication and presentation to pediatric emergency departments, especially in winter. The primary aim of this study was to evaluate the demographic characteristics, and clinical and laboratory findings of pediatric patients who presented to the pediatric emergency department with carbon monoxide poisoning, and the secondary aim was to examine the laboratory values of the patients with impaired consciousness. Material and Methods: The demographic and clinical characteristics and laboratory values of 162 patients presented to the pediatric emergency department due to carbon monoxide poisoning between 2017 and 2020 were retrospectively analyzed. The laboratory parameters of the patients with and without symptoms of impaired consciousness were compared. Results: The mean age of the patients was 8.94±5.33 years, and the gender distribution was homogenous. The highest frequency of presentation was during winter. Nausea, vomiting, and headache were the most common symptoms. Fifteen of the patients had impaired consciousness. While the laboratory values of the patients were generally within normal ranges, patients with high carboxyhemoglobin, lactate, and troponin values, and low pH were encountered. The carboxyhemoglobin and lactate levels of patients with impaired consciousness were found to be significantly higher than the patients without impaired consciousness (p<0.001 and p=0.019, respectively). Conclusion: Elevated carboxyhemoglobin and lactate levels were associated with impaired consciousness. Although carboxyhemoglobin levels are important for diagnosis and clinical follow-up, they should not be used as the only marker. High lactate and troponin levels, and low pH should also be taken into account

A CAD of fully automated colonic polyp detection for contrasted and non-contrasted CT scans

Osman, Onur (Arel Author)Computer-aided detection (CAD) systems are developed to help radiologists detect colonic polyps over CT scans. It is possible to reduce the detection time and increase the detection accuracy rates by using CAD systems. In this paper, we aimed to develop a fully integrated CAD system for automated detection of polyps that yields a high polyp detection rate with a reasonable number of false positives. The proposed CAD system is a multistage implementation whose main components are: automatic colon segmentation, candidate detection, feature extraction and classification. The first element of the algorithm includes a discrete segmentation for both air and fluid regions. Colon-air regions were determined based on adaptive thresholding, and the volume/length measure was used to detect air regions. To extract the colon-fluid regions, a rule-based connectivity test was used to detect the regions belong to the colon. Potential polyp candidates were detected based on the 3D Laplacian of Gaussian filter. The geometrical features were used to reduce false-positive detections. A 2D projection image was generated to extract discriminative features as the inputs of an artificial neural network classifier. Our CAD system performs at 100% sensitivity for polyps larger than 9 mm, 95.83% sensitivity for polyps 6-10 mm and 85.71% sensitivity for polyps smaller than 6 mm with 5.3 false positives per dataset. Also, clinically relevant polyps (6 mm) were identified with 96.67% sensitivity at 1.12 FP/dataset.To the best of our knowledge, the novel polyp candidate detection system which determines polyp candidates with LoG filters is one of the main contributions. We also propose a new 2D projection image calculation scheme to determine the distinctive features. We believe that our CAD system is highly effective for assisting radiologist interpreting CT

Formaldehit ile işlem görmüş soya küspesinin rumende korunmuş protein miktarı ve ince bağırsaklarda aminoasit emilimi üzerine etkisi

Bu araştırma formaldehit ile işleme tabi tutulmuş soya küspesinin rumen fermantasyonu, mikrobiyal protein sentezi korunmuş protein (by-pass protein) miktarı ve ince bağırsaklarda amino asit emilimi üzerine etkilerini incelemek amacıyla yapılmıştır. Araştırmada hayvan materyali olarak, rumen duodenal ve ileal kanül takılmış 4 adet 1 yaşlı morkaraman koç kullanılmıştır. Yem materyali olarak günlük 800 g kuru yonca ve ağırlıklarının %8'i oranında su ve ham protein miktarlarının % 0, 0,3, 0,6 ve 0,9 düzeyinde saf formaldehit içeren solüsyonlarla işleme tabi tutulmuş 100 g soya küspesi verilmiştir. Duodenuma geçen günlük ham protein miktarı formaldehit işleminden etkilenmezken, günlük mikrobiyal ham protein miktarı özellikle % 0,3 ve 0,6 formaldehitli gruplarda azalmıştır (P < 0,05). Duodenum ve ileum ADF ve NDF sindirimleri bakımından gruplar arasında farklılık olmamıştır. Özellikle % 0,3 ve 0,6 düzeyinde uygulanan formaldehit işlemi duodenumdan esansiyel amino asitlerin (arjinin, histidin, löysin, metionin, fenilalanin ve valin) ve nonesansiyel amino asitlerin (alanin, aspartic asit) emilimini önemli derecede artırırken, tirozin emilimini azaltmıştır (P < 0,05). Esansiyel (löysin, valin) ve nonesansiyel amino asitlerin (serin, tirozin) ileumdan emilimi formaldehit uygulaması ile önemli derecede artmıştır (P < 0,05). Duodenumdan günlük toplam esansiyel amino asit emilimi de formaldehit uygulaması ile önemli derecede artırmıştır (P < 0,05). Sonuç olarak, % 0,3 ve % 0,6 formaldehit muamelesi soya küspesinin biyoyararlanilabilirliğini artırmıştırThis study was conducted to determine the effects of soybean meal (SBM) treated with formaldehyde on rumen fermentation pattern, microbial protein synthesis, amount of by-pass protein, and amino acid absorption from small intestines. Four 1-year-old rams with ruminal, duodenal, and ileal cannulas were fed 800 g of dry clover plus a concentrate mixture containing 100 g of SBM treated with 0%, 0.3%, 0.6%, and 0.9% formaldehyde. The amount of crude protein passed through the duodenum was not affected by the formaldehyde treatment; however, the amount of microbial protein decreased in rams fed with SBM treated with both 0.3% and 0.6% formaldehyde (P &lt; 0.05). Digestibility of acid detergent fibre (ADF) and neutral detergent fibre (NDF) in the duodenum and ileum did not differ by treatments. In the rams fed SBM treated with both 0.3% and 0.6% formaldehyde, absorbability of arginine, histidine, leucine, methionine, phenylalanine, and valine (essential amino acids), as well as alanine and aspartic acid (non-essential amino acids) significantly increased, whereas tyrosine absorbability notably decreased (P &lt; 0.05). Formaldehyde treatment increased the absorbability of other essential amino acids (leucine and valine) and non-essential amino acids (serine and tyrosine) in the ileum (P &lt; 0.05). Increasing the percentage of formaldehyde linearly increased total essential amino acid absorption in the duodenum (P &lt; 0.05). In conclusion, 0.3% and 0.6% formaldehyde treatment enhanced the bioavailability of protein in SBM

Determining Phase Duration of Scanning EMG Signals

There are more than one motor unit activities recorded simultaneously during scanning EMG recordings. It is not possible to determine the phase duration correctly by inspecting only one sweep. The other motor unit activities, which are out of interest, should be filtered for this purpose. In this study, a new method is developed by revealing the activity corridor of scanning EMG recordings, wavelet transform based noise reduction, autocorrelation function based signal cutting location detection, and alpha trim filtering are applied to the recorded signals for determining phase duration correctly. Data are recorded from normal people and neuromuscular diseased people. Dataset contains 20 scanning EMG recordings

Determining MUAP Activity Corridor In Scanning EMG Recordings

International Symposium on Innovations in Intelligent SysTems and Applications (INISTA 2015) --SEP 02-04, 2015 -- Madrid, SPAINWOS: 000380428200042In scanning EMG recordings there are more than one motor unit activity which is recorded by concentric needle electrode. Especially for determining features of a motor unit action potential (MUAP) such as phase duration and number of peaks easily, first the other motor unit activities must be discarded. In this study a new method is proposed to determine the activity corridor that related with the motor unit to be examined in scanning EMG recordings. This method is comprised of wavelet transform based noise reduction and autocorrelation function based location detection. Number of 34 scanning EMG recordings was tested by using this method and the activity corridors were determined correctly.Univ Autonoma Madrid, Ai+d
