A Survey on Data Mining Techniques for Prediction of Heart Diseases

International audienceHeart disease (HD) is a disease of the heart or blood vessels, which causes death. In recent scenario, health issues are huge, due to this nature predicting and classifying into different conditions are very tedious. The field of data mining has involved in those domains to predict and to classify the abnormality along with its risk level. The previous studies have used several features to diagnosis the disease, which has been collected from patients. By applying different data mining algorithms, the patient data can be used for diagnosis as training samples. The main drawbacks of the previous studies are that need accurate and more number of features. This paper surveys about the recent data mining techniques applied for predicting heart diseases

ANTIMICROBIAL AND ANTIOXIDANT ACTIVITY OF CYCAS CIRCINALIS.L AND IONIDIUM SUFFRUTICOSUM. GING

Herbs with antioxidants and antimicrobial activity play a vital role in prevention and cure of certain complex diseases. Cycas circinalis and Ionidium Suffruticosum are the herbs taken to study its antimicrobial and antioxidant activity. The ethanolic extract of the above 2 herbs were taken and the antimicrobial activity was studied by Kirby-Bauer disk diffusion method and the antioxidant activity was analyzed by percentage inhibition of DPPH activity. Around 8 species of microorganisms were taken for antimicrobial assay. The Cycas circinalis showed 0.7mm of zone of inhibition for Staphylococcus aureus in culture whereas Ionidium Suffruticosum showed 1mm and 0.4 mm of zone of inhibition for Escherichia colli and Salmonella typhi respectively. The rest of all species were non-reactive for both the herbal extracts. The IC50 values of I.suffruticosum at various concentrations were 95.6, 96.0 and 97.6 respectively whereas for C.circinalis, it was 78.7, 85.9 and 87.5 respectively. The IC50 value of I.suffruticosum shows that the herb has more antioxidant property when compared to that of C.circinalis and standard (ascorbic acid). The study shows that I.suffruticosum and C.circinalis both have mild antimicrobial activity acting only on 2 species of bacteria and the rest were dormant. I.suffruticosum and C.circinalis both were found to have antioxidant activity. This is a preliminary study done on the above 2 herbs which is a part of vast ongoing research work

Nonintegrability of (2+1)-dimensional continuum isotropic Heisenberg spin system: Painlev\'e analysis

While many integrable spin systems are known to exist in (1+1) and (2+1) dimensions, the integrability property of the physically important (2+1) dimensional isotropic Heisenberg ferromagnetic spin system in the continuum limit has not been investigated in the literature. In this paper, we show through a careful singularity structure analysis of the underlying nonlinear evolution equation that the system admits logarithmic type singular manifolds and so is of non-Painlev\'e type and is expected to be nonintegrable.Comment: 11 pages. to be published in Phys.

ARCUATE FORAMEN OF ATLAS VERTEBRA

ABSTRACTThe Arcuate foramen is a bony arch which connects the posterior end of the superior articular fossa with the posterior arch of atlas. In case of presence of arcuate foramen the vertebral artery follows the normal course but it has to traverse through the osseo fibrous ring (arcuate foramen).Aim & ObjectivesTo determine the height, width, and area of arcuate foramen and to determine the morphometric difference between the transverse foramen and the canal formed by bony bridges over the vertebral artery of the atlas vertebra.Materials & MethodsA total of 75 dry human atlas vertebrae were taken for the study. These vertebrae were examined carefully for the presence of arcuate foramen. Measurements of the maximum dimensions of the arcuate foramen and foramen transversarium were taken. Area of the arcuate foramen was calculated. Differences in dimension of arcuate foramen  and foramen transversarium were compared. Side differences of arcuate foramen were compared using the unpaired Student's t test.ResultsThe dimension of arcuate foramen of both sides as compared with dimension of foramen transversarium was found to be more, so the chance of compression of vertebral artery on both sides was less. The percentage of occurrence of arcuate foramen was 2.25% (bilateral) and ponticles was (1.5%) unilateral. ConclusionThe dimension of arcuate foramen was more when compared to foramen Transversarium dimensions so the chances of compression of vertebral artery would be less. The knowledge of these foramina may be important for orthopedic surgeons, radiologists, neurosurgeons, and anthropologists. KEYWORDS -Ponticulus Posticus, Arcuate Foramen, Atlas Vertebra, Foramen Transversarium

A Study on Cardiopulmonary Manifestations in Inflammatory Myositis.

INTRODUCTION : The Inflammatory Myopathies encompass a group of heterogenous muscle disorders which share the clinical features of slowly progressive weakness of skeletal muscle, decreased muscle endurance and muscle fatigue. Another common feature is presence of inflammatory infiltrates, mainly composed of T cells and macrophages, in muscles tissue. Autoantibodies are also frequent in patients with inflammatory myopathies. The presence of infiltrating lymphyocytes in the target organ, the muscles, and autoimmune disease but a target autoantigen has not been determined. Although muscle symptoms predominate in myositis patients, other clinical manifestations are common. Besides skin rash, which by definition is present in dermatomyositis patients, interstinal lung disease is a frequently observed extramuscular manifestations, as are arthritis, Raynaud’s phenomenon and gastrointestinal involvement. Moreover, myositis is often observed in patients with other connective tissue diseases, particularly in those with systemic sclerosis, mixed connective tissue disease (MCTD) and Sjogren’s syndrome and occasionally in patients with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE). These observations suggests that the idiopathic inflammatory myopathies are systemic inflammatory connective tissue disorders and that there could be etiological factors or pathogenic mechanisms that are shared with other connective tissue diseases. AIMS AND OBJECTIVES : To determine the various cardiopulmonary manifestations in inflammatory myositis. MATERIALS AND METHODS : The study was conducted in the Department of Rheumatology, Madras Medical College, Chennai-3 from February 2011 to January 2012, after ethical committee clearance. Total number of patients included in the study is 50 who fulfills inclusion criteria. All these patients were subjected to clinical examination, CBC, RFT, LFT, CRP, RF, Muscle enzymes (CPK, LDH, SGOT, SGPT) ECG, ECHO, PFT, HRCTLung, CXR, Broncho Alveolar Lavage (BAL), auto antibody profile (ANA, ENA Profile), muscle biopsy, ultra sound abdomen and EMG studies. Inclusion Criteria : 1. Patients fulfilling Bohan & Peter criteria for idiopathic inflammatory myositis. 2. Patients with overlap syndromes presenting with inflammatory myositis. Exclusion Criteria : 1. Features of congenital myopathy, 2. Features of metabolic myopathy, 3. Features of Drug induced myopathy, 4. Features of Endocrine myopathy, 5. Features of muscular dystrophy, 6. H/o. Pulmonary TB in the past, 7. H/o. Diabetes Mellitus, 8. H/o. Exposure to irradiation to body. RESULTS : HRCT lung was done in 42 cases. HRCT lung involvement in the form of interstitial infiltrates, Non Specific Interstitial Pneumonitis (NSIP), Usual Interstitial Pneumonitis (UIP), nodular, reticular patterns, ground glass opacities and traction bronchiectasis were seen in 21(50%) out of 42 patients. In our study, various patterns of lung involvement in inflammatory myositis are 1. NSIP (Non specific interstitial Pneumonitis) characterized by reticular and or ground glass opacities with or without consolidation are seen in 15 (71%) out of 21 patients. 2. Honey combing, bronchiectatic changes with fibrosis seen in 4 (19%) patients out of 21. 3. UIP (Usual Interstitial Pneumonia) 2 (9.5%) patients out of 21. 4. Cryptogenic organizing pneumonia, diffuse alveolar damage were not seen in our study. 5. Pleural effusion with consolidation was seen in 1 case of SLE myositis overlap. CONCLUSION : In out study, inflammatory myositis is more common in females than in males. In our study, myositis is more common in overlap syndromes compared to Idiopathic Inflammatory Myositis. In our study, among the overlap syndromes SLE with myositis overlap is more common. In our study, ILD was seen in 50% of the adult patients with NSIP being the most common. In our study, a symptomatic ECG abnormalities was common (48%). In our study, 58% of the patients showed inflammatory cells in the BAL study, out of which 52% of the patient had ILD changes by HRCT Lung. In patients with myositis, routine use of HRCT Lung and ECG evaluation is more useful

Sex Determination by Morphometry of Eyes

Background: Facial anthropometrics are affected by various factors such as age, sex, ethnicity,socioeconomic status, environment and region. The anthropometric analysis of face is essential for craniofacial plastic and reconstructive surgeries. Aim & Objectives: The purpose of this study was to create a baseline data in determining the sex of the people from India and Malaysia depending on morphometry of eyes. Material and Methods: A total of 100 Malaysians and 100 South Indians were enrolled for the study. Various morphometric measurements of eyes were taken using Digital Vernier caliper. The data were analyzed by independent t test for comparison of sides and one way ANOVA to find out the significance among the sex and populations. Results:The height of upper and lower eye lid were higher in females as compared to that of males whereas depth of eyes and interpupillary distance were higher in males than in females and thus sexual dimorphism exists. Fissure height and biocular width were more in Indian males when compared to Indian females. Fissure height and interocular width were more in Malaysian female when compared to other groups. Indian males and females differed significantly in upper and lower eye lids height from Malaysian males and females. All eye morphometric parameters except interpupillary distance were increased in Malaysians when compared to Indians thus ethnic variations also exist. Conclusion: The facial aesthesis is highly contributed by eye appearance and symmetry, facial rejuvenation by a plastic surgeon requires morphometric data of eye

Moisture management properties of eri silk knitted fabrics

389-395Moisture management and wicking properties of eri silk knitted fabrics have been studied. Three different knit structures, namely single jersey, single pique and honeycomb, have been developed with the combination of two different yarn count and tightness level. The fabrics developed are analyzed in terms of wetting time, spreading speed, absorption rate, and maximum wetting radius, accumulative one way transport index (AOTI) and overall moisture management capacity (OMMC). It is discerned that the variables, such as yarn count, fabric tightness and knitting structure, have a significant influence on the wicking and moisture management properties. The OMMC indexes of eri silk knitted fabric are found to range from ‘very good’ to “excellent’ category, which indicates the suitability of eri silk yarn to skin fit as well as active wear applications
