Hydatid cyst of ovary- a rare entity
Sailes Ray,Mimi Gangopadhyay
Journal of the Turkish-German Gynecological Association , 2010,
Abstract: Hydatid disease is a zoonosis caused by the larval stage of Echinococcus granulosus. It is prevalent in areas where livestock is raised in association with dogs. Humans are the accidental intermediate host. Primary peritoneal echinococcosis is a rarely observed clinical condition. We report a case of peritoneal hydatid cyst diagnosed incidentally during an operation performed for suspected ovarian cyst.
Addressing Issues of Social Justice through Reflective Writing  [PDF]
JaDora Sailes
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.41006
Abstract:

Since the1960’s there have been calls for reforms in teacher education programs to reflect the growing diversity represented in our nation’s schools. One response is multicultural education courses aimed at addressing attitudes and beliefs about diversity. Such courses have received mixed reviews. Some research has reported that pre-service teacher’s attitudes and beliefs were changed in a positive direction towards diversity, while others suggest that pre-service teachers leave these courses unchanged. The primary goal of this study was to determine if a stand-alone multicultural education course challenged or altered pre-service teachers’ attitudes and beliefs towards cultural diversity. An analysis of reflective writings by the participants throughout the semester served as evidence of change.

Guided fine needle aspiration cytology of retroperitoneal masses - Our experience
Gangopadhyay Mimi,Bhattacharyya Nirmal,Ray Sailes,Chakrabarty Subrata
Journal of Cytology , 2011,
Abstract: Background : Early pathological classification of retroperitoneal masses is important for pin-point diagnosis and timely management. Aims : This study was done to evaluate the usefulness and drawbacks of guided fine needle aspiration cytology (FNAC) of retroperitoneal masses covering a period of two years with an intention to distinguish between neoplastic and non-neoplastic lesions and to correlate with histologic findings. Materials and Methods : FNAC was done under radiological guidance in all cases using long needle fitted with disposable syringe. Appropriate staining was done and cytology was correlated with histology which was taken as the gold standard for comparison. Results : Fifty-one patients who presented with retroperitoneal masses were studied. Forty-four lesions were malignant cytologically and 7 were inflammatory (tuberculous). According to radiological and cytologic findings, we classified our cases into four groups: renal tumors, retroperitoneal lymphadenopathy, germ cell tumors, soft tissue tumors. Except for cases of non-Hodgkin lymphoma (NHL) and metastatic lesions, we had sensitivity and specificity of 100%. In NHL the sensitivity and specificity were both 50%. In cases of metastatic adenocarcinoma, the sensitivity and specificity were 84.6% and 81.8%, respectively. Conclusions : Ignoring the pitfalls, guided FNAC is still an inexpensive and reliable method of early diagnosis of retroperitoneal lesions.
Calcified pure uterine lipoma mimicking myoma
Arghya Bandopadhyay,Sailes Ray,Pranati Bera,Mimi Gangopadhyay
Journal of the Turkish-German Gynecological Association , 2010,
Abstract: Pure lipoma of the uterus is a rare entity and only a few cases have been reported in the literature. Clinical symptoms and signs are similar to those found in leiomyoma and create preoperative diagnostic confusion. The histogenesis is still unclear. We report the case of a 70 year-old woman with pure lipoma of the uterus with calcification.
Recent interests on positron (e+ ), positronium (Ps) and antihydrogen (H)  [PDF]
Hasi Ray
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.31005
Abstract: A brief survey is made to highlight the recent interests in positron, positronium and antimatter physics. Positron is the first antiparticle observed which was predicted by Dirac. Positronium is itself its antiparticle and bi-positronium molecule is recently observed in laboratory which was predicted by Wheeler in 1946. The simplest antiatom i.e. antihydrogen is observed in the laboratory and the process to achieve the stable confinement of antihydrogen within the trap are in progress to test the standard model.
Disabling hip osteoarthritis: gender, body mass, health and functional status correlates  [PDF]
Ray Marks
Health (Health) , 2010, DOI: 10.4236/health.2010.27106
Abstract: Objective: To examine gender differences in self-reported pain and function before and after hip replacement surgery and the extent to which overweight, comorbidities and muscular status impact pain and function in adults with disabling end-stage hip joint osteoarthritis. Setting: Orthopedic Hospital Setting on the East Coast of the United States. Study Design: Cross-sectional retrospective chart review. Methods: The desired demographic, physical and psychological attributes of 1040 adults with end-stage hip osteoarthritis hospitalized for hip surgery were recorded and subjected to comparison and correlational analyses. These data included gender, self-reported weight, height, numbers and nature of physical and psychological comorbidities, pain intensity, ambulatory capacity and discharge destination. Sub-group analyses of 808 candidates hospitalized for primary unilateral surgery were also conducted using SPSS 16. Results: There were significant (p < 0.05) associations between gender, pain scores, comorbidity numbers and ambulatory capacity. Specifically, women who exhibited higher comorbid disease rates than men, exhibited higher pre-surgery pain levels and greater functional limitations in walking ability before and after surgery than men with the same condition. In sub-group analyses of men and women with the same mean age, comorbid prevalence rates, and body mass indices, women were found to have significantly higher ideal weights on average than men, and those with higher ideal weights recovered more slowly after surgery (p < 0.05). Conclusion: The presentation of hip joint osteoarthritis is not uniform, and may be impacted differentially by gender. Women with high ideal body weights, may be specifically impacted. Whether genetic or other factors account for gender differences in pain and function among adults with disabling hip osteoarthritis observation needs to be examined.
Osteoarthritis and Articular Cartilage: Biomechanics and Novel Treatment Paradigms  [PDF]
Ray Marks
Advances in Aging Research (AAR) , 2014, DOI: 10.4236/aar.2014.34039
Abstract:

Background: Osteoarthritis is a widespread highly painful disabling age-related disease with no known cure. Although novel strategies for ameliorating osteoarthritic damage abound, it is likely that none will be successful over time if the entire spectrum of the disease and the effects of joint biomechanics on joint tissues are not carefully considered. Objectives: 1) To detail the structure of healthy articular cartilage, the key tissue affected by osteoarthritis. 2) To detail what aspects of cartilage damage best characterize osteoarthritis. 3) To consider the role of biomechanical factors in developing solutions to treat osteoarthritic joint damage. Methods: Literature sources from 1980 onwards that have contributed to our knowledge of the topics relevant to this paper were accessed and retrieved. The data were categorized into four predominant themes and conclusions about the state of our knowledge and future directives were formulated. Conclusions: Osteoarthritis prevalence remains high, and a cure appears elusive. A rich body of data has helped us to better understand the key tissue involved, and suggests a repair process might be feasible, if the basic collective information on the role of biomechanics in mediating or moderating articular cartilage integrity and function is forthcoming.

The Ethical Implications for Humans in Light of the Poor Predictive Value of Animal Models  [PDF]
Ray Greek
International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.516129
Abstract:

The notion that animals could be used as predictive models in science has been influenced by relatively recent developments in the fields of complexity science, evolutionary and developmental biology, genetics, and evolutionary biology in general. Combined with empirical evidence, which has led scientists in drug development to acknowledge that a new, nonanimal model is needed, a theory—not a hypothesis—has been formed to explain why animals function well as models for humans at lower levels of organization but are unable to predict outcomes at higher levels of organization. Trans-Species Modeling Theory (TSMT) places the empirical evidence in the context of a scientific theory and thus, from a scientific perspective, the issue of where animals can and cannot be used in science has arguably been settled. Yet, some in various areas of science or science-related fields continue to demand that more evidence be offered before the use of animal models in medical research and testing be abandoned on scientific grounds. In this article, I examine TSMT, the empirical evidence surrounding the use of animal models, and the opinions of experts. I contrast these facts with the opinions and positions of those that have a direct or indirect vested interest—financial or otherwise—in animal models. I then discuss the ethical implications regarding research constructed to find cures and treatments for humans.

Non-Operative Management of Hip Osteoarthritis  [PDF]
Ray Marks
Pain Studies and Treatment (PST) , 2015, DOI: 10.4236/pst.2015.32002
Abstract: This paper reviews several non-operative and non-pharmacologic management strategies advocated for alleviating the pain and disability experienced by people with hip osteoarthritis. It analyzes whether painful debilitating hip osteoarthritis, which has no effective cure and is often progressive, may be affected positively by non-operative interventions designed to control osteoarthritis pain. Finally, it provides an integrated plan of management for ameliorating hip osteoarthritis pain and disability in light of this knowledge.
Is Blended Learning Making Us Stupid, Too?  [PDF]
Ray Archee
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.39010
Abstract:

The title of this paper echoes Nicholas Carr’s (2008) article, Is Google Making Us Stupid?, which evoked heated debate around the issue of whether the Internet was having negative effects upon human concentration and learning. While this paper agrees that blended learning has the same issues as the Internet, blended learning is under the control of organizations, institutions, instructors and students. Whether our brains are being changed for better or worse is not the critical question, but how much confidence we ascribe to blended learning. This paper argues that blended learning should be regarded as blended teaching because the phrase comprises a contested assumption. Educators, by their selection of traditional and online media, have complete control over this teaching, but students, in the end, are the ultimate arbiters of their own learning.
