Abstract: Variations of the external iliac artery are very rare. We found a rare variation in the left external iliac artery. The artery was long and formed a characteristic loop. The loop was found in the lesser pelvis in close relation to the obturator nerve. This loop may compress obturator nerve and vessels. The knowledge of this loop might be important for gynaecologists, orthopaedic surgeons and urologists since it may be involved in surgeries of hip, ovary and prostate. Las variaciones de la arteria ilíaca externa son raras. Se encontró una variación poco frecuente en la arteria ilíaca externa izquierda. La arteria era larga y formaba un bucle característico. El bucle se encontró en la pelvis menor en estrecha relación con el nervio obturador. Este circuito puede comprimir el nervio obturador y los vasos circundantes. El conocimiento de este circuito podría ser importante para los ginecólogos, cirujanos ortopédicos y urólogos, ya que pueden estar involucrados en las cirugías de cadera, ovario y próstata.
Hypoplastic plexiform right anterior cerebral artery and absence of anterior communicating artery—A case report  [PDF]
Satheesha Nayak Badagabettu, Anitha Guru, Surekha Devadasa Shetty, Srinivasa Rao Sirasanagandla
Forensic Medicine and Anatomy Research (FMAR) , 2013, DOI: 10.4236/fmar.2013.13009
Abstract: Anterior cerebral artery is the smaller terminal branch of the internal carotid artery. It is one of the arteries involved in the formation of the arterial circle of Willis at the base of the brain. Its hypoplasia or absence can cause serious problems during neurosurgery or in the vascular dynamics of the brain. We found a rare variation of the right anterior cerebral artery during the dissection of the brain. The initial segment of the artery was hypoplastic and plexiform. The anterior communicating artery was absent. The right and left anterior cerebral arteries fused with each other for a distance of about 1 cm. The course, size and distribution of the distal part of the right anterior cerebral artery were normal. This case may be of special importance to neurosurgeonsand radiologists. Obstructionor rupture of the left anterior
cerebral artery in such cases might result in infarct of the medial surfaces of both cerebral hemispheres.
CYP2D6*4 polymorphisms and breast cancer risk
D Surekha
Biology and Medicine , 2010,
Abstract: CYP2D6 gene plays an important role in detoxification of many drugs and plays a crucial role in the metabolism oftamoxifen, used in endocrine therapy. In the present study, the heterozygous frequency IM (40.8%) was significantlyincreased in breast cancer patients when compared to controls. When the data on IM and PM were pooled,significant increase in the frequency of pooled genotype in disease group (42.4%) was observed as compared tocontrols (27.6%). The frequency of IM genotype was found to be increased in women with premenopausal breastcancer patients (43.5%) and patients with familial history of cancer (43.2%). Higher frequency of IM as well as pooledgenotypes PM+IM was found in cases with higher BMI and in patients occupied in agriculture (55.6%), patientspositive for estrogen receptor (47.8%), progesterone receptor (44.8%), HER2/neu (26.9%) and advanced stage. Ourresults suggested that the CYP2D6*4 polymorphism plays an important role in the breast cancer etiology and mighthelp in planning hormonal therapy where tamoxifen is used.
Prevalence of obesity among the medical students: a cross sectional study in a south Indian medical college
Surekha Kamath,Jessica D’Souza
Al Ameen Journal of Medical Sciences , 2013,
Abstract: Introduction: In recent years obesity has become very common health concern worldwide. Much debate has been generated regarding the increasing incidence of obesity among children and adolescents with respect to their long term health benefits. Obesity has always been associated with what we eat and how we eat. Thus, the objective of our present study was to determine the relationship between eating speed and obesity among medical students of Melaka Manipal Medical College, Manipal, India. We also aimed at finding out the factors that affect the eating speed of a person. Methods: A survey was conducted for the first year medical students of MMMC, Manipal campus. The participants consisted of 506 students aged 18-24 years. The survey included a self-administered questionnaire. The questionnaire included a diet history items that required recall of dietary habits over 2 months. Weight and height of the participants were taken in order to calculate Body mass index (BMI), which was calculated as weight in kilograms divided by the square of height in meters. Comparison between the speed of eating and the BMI values were obtained for analysis. Results: Our results showed that the majority of the obese subjects are linked to very fast eating rate which is less than 15 minutes. It is made up of 65% of the total number of subjects in obese category. Conclusion: Our study, found a positive correlation between the eating rates and BMI in students between the age group 18-24. This shows that the rate of eating can be a causative factor for obesity.
Legal Awareness—Hubris for Women to Combat Violence  [PDF]
Pravabati Guru
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.39030
Abstract: Legal awareness is a sine qua non to combat violence against women. India is the first country to introduce the Protection of Women from Domestic Violence Act-2005 and a number of other laws to empower women. “Are women really legally aware” is a critical question. All the national news- papers are embedded with news about violence against women, which include both domestic and professional front. Though Government of India has enacted a number of laws to empower and protect women from violence, these laws are not that effective due to lack of awareness among women of the country. The present study explored the level of legal awareness among women of different professions, education, and income and its impact on their real life as it related to violence. The findings showed that a positive relationship existed between education, income, professional work and legal awareness. It was also observed that legal awareness and victimization of women were inversely related.
Stem cells - A window to Regenerative Dentistry
Rajender Amireddy,Seetaram Kumar D,Surekha Murthi
Indian Journal of Dental Advancements , 2010,
Abstract: With the better understanding of molecular biology, stem cell research is advancing resulting in search for biological solutions for biological problems. Stem cells self renew and form multiple cell types. These pluripotent stem cell populations persist in multiple organs and when stimulated they proliferate and differentiate in response to local cues provided by the organs they are recruited to. Stem cells have been successfully isolated from variety of human tissues including dentofacial tissues. Stem cells are offering new potential to treat diseases, to screen new drugs in laboratory and to develop model systems to study normal growth and identify the causes of birth defects. This article focuses on various sources of stem cells and their applications in orofacial region.
MOVING VEHICLES EXTRACTION IN TRAFFIC VIDEOS
ELHAM DALLALZADEH and GURU D.S.
International Journal of Machine Intelligence , 2011,
Abstract: In this paper we propose two different approaches to segment and extract moving vehicles in traffic videos. Background subtraction is used to extract foreground frames. Different types of moving vehicles are then segmented by first proposed hybrid approach which combines a connected component analysis and a semi-supervised thresholding. In the second proposed approach, Gabor filtering method is used for segmentation of moving vehicles. The robustness and efficacy of our proposed approaches are elaborated by experiments conducted on real traffic videos captured under complex background, variations in illumination, motion, position of a camera and different moving directions during day time. The presented results are as well compared with 2 well-known methods of GMM and W4 used in extraction of moving vehicles.

International Journal of Machine Intelligence , 2011,
Abstract: In this paper, we address the problem of shot boundary detection, which is an essential pre-processing step invideo analysis applications. We present a novel model for detection of shot boundaries based on eigen conjugation ofadjacent frames. Also, in this paper we present a method of classifying the shot boundaries using template matchingtechnique. Experimentation is carried out on two different categories of videos such as entertainment videos and sportsvideos.
Critical current and linewidth reduction in spin-torque nano-oscillators by delayed self-injection
Guru Khalsa,M. D. Stiles,J. Grollier
Physics , 2015,
Abstract: Based on theoretical models, the dynamics of spin-torque nano-oscillators can be substantially modified by re-injecting the emitted signal to the input of the oscillator after some delay. Numerical simulations for vortex magnetic tunnel junctions show that with reasonable parameters this approach can decrease critical currents as much as 25 % and linewidths by a factor of 4. Analytical calculations, which agree well with simulations, demonstrate that these results can be generalized to any kind of spin-torque oscillator.
