Sontakke, Subodh Arun,Karjodkar, Freny R.,Umarji, Hemant R. Korean Academy of Oral and Maxillofacial Radiology 2011 Imaging Science in Dentistry Vol.41 No.1

Purpose : This study was to find the computed tomographic features of fibrous dysplasia of the maxillofacial region. Materials and Methods : All eight cases included in the study reported either to Government Dental College and Hospital or Nair Hospital Dental College, Mumbai between 2003 and 2009. The patients were prescribed computed tomogram in addition to conventional radiographs of maxillofacial region which were studied for characteristic features of fibrous dysplasia. The diagnosis of fibrous dysplasia was confirmed by histopathological report. Results : All cases showed the ill-defined margins of lesions except in the region where the lesions were extending to cortex of the involved bone. Internal structure of all cases showed ground glass appearance. Four cases of maxillary lesion showed the displacement of maxillary sinus maintaining the shape of maxillary sinus. Two cases showed complete obliteration of maxillary sinus. Displacement of inferior alveolar canal did not follow any typical pattern in any of the cases but was displaced in different directions. Conclusion : The craniofacial type of fibrous dysplasia is as common as fibrous dysplasia of jaw. The margins, extent, internal structure and effect on surrounding structure are well detected on computed tomographic images.

Sontakke, Sneha B.,Jung, Jin-hee,Piao, Zhe,Chung, Hye Jin American Chemical Society, Books and Journals Divi 2016 Journal of agricultural and food chemistry Vol.64 No.38

<P>Collagen-derived small peptides, such as Gly-Pro-Hyp (GPH) and Pro-Hyp (PH), play a role in various physiological functions. Although collagen degrades in the gastrointestinal tract randomly and easily, it is not readily cleaved into bioactive peptides. To increase the bioavailability of bioactive peptides, a collagen tripeptide (CTP) was prepared from fish scales by the digestion method using collagenase from nonpathogenic Bacillus bacteria. It was demonstrated that Hyp-containing peptides GPH and PH were better absorbed and reached higher plasma levels after the oral administration of CTPs in rats compared to high molecular weight collagen peptide (H-CP). GPH and PH were stable in gastrointetiiial:fluid and rat plasma for 2 h, and GPH was able to be transported across the intestinal cell monolayer. These results suggest that :the ingestion of CTP is an efficient method for taking bioactive peptides orally due to the enzymatic stability and intestinal permeability of GPH and PH.</P>

Palash Sontakke,Chang-Soo Kim 한국디지털융합학회 2018 IJICTDC Vol.3 No.1

The global population is increasing rapidly because of increasing urbanization and such increasing urbanization directs the up-growing need of urban safety and preventions. This urbanization is also responsible for two things that is increased job opportunities and increased the crime rates. In this era technology has gone far more forward in a positive way. By making use of these technologies such as machine learning, artificial intelligence and big data we presented an approach through which crime pattern analysis is done. We have used apache spark (scala-programming) and machine learning algorithm for predictive crime pattern analysis. The data that we have used is a real-world data set based on Chicago city of United State of America. Our main goal of work is to define a predictive crime analysis which shows top crime patterns related to the top community areas of Chicago city.

A review on regulatory aspects, challenges and public perception in acceptance of genetically modified foods

A. Kanthi Naveen,Manmath Sontakke 한국식품과학회 2024 Food Science and Biotechnology Vol.33 No.4

A clear vision for the future of the world’s food supply must be developed by all stakeholders, including consumers, farmers, and governments, especially in light of the rapid improvements in the production of genetically modified crops. It has been possible through biotechnology and genetic engineering, genetically modified (GM) crops have been engineered to have certain qualities, such as resistance to pests, illnesses, or herbicides. Concerns about risks and unintended effects of GM crops include ecosystem impacts, new pests or diseases, and health effects on humans and animals. There is mounting evidence that consumers may respond unfavourably to the introduction of genetically altered foods. This research focuses at how genetic engineering can raise agricultural yields, improve nutrient content, and lessen the use for hazardous pesticides and herbicides in food production. Regulatory framework for GM foods may impact on perception and acceptance of consumers.

Computer Based an Analysis of Heart Rate Variability Signal in Prognosis of Diabetic Autonomic Neuropathy

SARIKA TALE,T.R.SONTAKKE 한국멀티미디어학회 2011 한국멀티미디어학회 국제학술대회 Vol.2011 No.-

The analysis of heart rate variability (HRV) signal is an important tool for studying the autonomic nervous system, as it allows the evaluation of the balance between the sympathetic and parasympathetic influences on heart rhythm. Time-frequency analysis of HRV makes it easier to evaluate how this balance varies with time. Among the various forms of autonomic disorders, Diabetic Cardiovascular Autonomic Neuropathy (DCAN) is a dreadful complication of diabetes therefore the use of HRV analysis in timely detection of diabetic autonomic neuropathy become of almost significance. This work presents a Electrocardiogram (ECG) signal preprocessing algorithm using Wavelet transform, a Pan-Tompkins algorithm for reliable QRS complex detection and to derive HRV signal from raw ECG signal. A tool for time domain analysis, Frequency domain analysis (Fast Fourier Transform (FFT), Auto-Regressive Model ing) of HRV signal developed in Matlab, Following the guidelines suggested by the Task force of the European Society of Cardiology. ECG data of 10 Diabetes Mellitus (DM) and 10 normal control volunteers were recorded and autonomic nervous system activities are quantified using the developed system. The analysis results shows a lower variation in time-frequency domain parameters of the Diabetics Mellitus (DM) patient group compared to normal subjects and p value <0.01.

Patil, Neha,Karjodkar, Freny R.,Sontakke, Subodh,Sansare, Kaustubh,Salvi, Rohini Korean Academy of Oral and Maxillofacial Radiology 2012 Imaging Science in Dentistry Vol.42 No.4

Purpose: This study was performed to evaluate the uniqueness and reliability of the frontal sinuses by comparing various patterns of frontal sinus as observed on Waters' radiographs for individual identification. Materials and Methods: Three Waters' radiographs of 100 individuals, taken on day one, after 6-8 months, and one radiograph with a slight variation in angulation, to mimic conditions out in the field or during autopsy. Three observers were randomly given radiographs from all there packets for comparisons and identification, by the method of superimposition and individual uniqueness. Results: The comparative identification by superimposition of the frontal sinus was 100% positive. The size, shape, unilateral or bilateral presence, absence, and septa were observed to be unique in each case; neither had the measurements changed over a period of time. Conclusion: The need to establish a reliable, low-cost, and easily reproducible method for human identification prompted the elaboration of technical, precise, and accessible parameters, such as the evaluation of the area, asymmetry, and shape of the frontal sinus. Comparison among each of the frontal sinuses of the 100 people in the sample revealed that no two sinuses are the same, that is, the sinus is unique to each individual.

Supernumerary teeth in non-syndromic patients

Mali, Santosh,Karjodkar, Freny Rashmiraj,Sontakke, Subodh,Sansare, Kaustubh Korean Academy of Oral and Maxillofacial Radiology 2012 Imaging Science in Dentistry Vol.42 No.1

Hyperdontia or supernumerary teeth without associated syndrome is a rare phenomenon, as supernumerary teeth are usually associated with cleft lip and palate or other syndromes such as Gardner's syndrome, cleidocranial dysplasia, and so on. Five patients with supernumerary teeth visited our department. They had no familial history or other pathology, certain treatment protocols was modified due to the presence of supernumerary teeth. Non-syndromic supernumerary teeth, if asymptomatic, need to have periodical radiographic observation. If they showed no variation as they impacted in the jaw, careful examination is necessary because they may develop into pathological status such as dentigerous cysts. The importance of a precise clinical history and radiographic examination for patients with multiple supernumerary teeth should be emphasized.
