A prospective comparative study to evaluate the efficacy of ultrasonography and hysteroscopy and their correlation with the histopathology of endometrium in a case of abnormal uterine bleeding

Background: Abnormal uterine bleeding (AUB) is one of the most common complaints that brings a woman to the gynecologist. Key to successful clinical management of AUB is to identify the cause behind it for which proper evaluation of the case is required. In current scenario of increasing cost awareness and taking risk related to invasive procedure hysteroscopy, a balance has to be achieved between the practices of randomly doing all investigation versus a condition appropriate approach. This study was done to compare efficacy of pelvic ultrasonography & hysteroscopy in cases of AUB and their correlation with the histopathology of endometrium.Methods: In this study 70 women with AUB were selected as they presented in OPD. After evaluation of clinical presentation, general, systemic and local examination, ultrasonography and hysteroscopy were performed on every patient and endometrial curetting were sent for histopathology.Results: We concluded that ultrasonography has a better efficacy to detect uterine cause of AUB and hysteroscopy is better for detecting intracavitary lesions.Conclusions: Ultrasonography has a better efficacy to detect uterine cause of AUB. However a thorough history and detailed clinical examination plays a very important role in narrowing the differential diagnosis of AUB. We have developed an algorithmic approach and guidelines for selective use of hysteroscopy in cases of AUB after evaluating the results

LOCATION BASED ADVERTISING FOR MASS MARKETING

GIS and machine learning (ML) are powerful ICT tools in retail industry which helps the sellers understand their markets. For the consumers, however, there always lies an ambiguity with respect to the quality and quantity of the product to be purchased, vis-à-vis the price paid for it. Most retail businesses today adopt “Discount Pricing Strategies” or “Offers” to make new customers and increase sales. Owing to several establishments selling the same product and offering a variety of offers, the process of identifying the shops where the consumer can get the best value for his money, requires a lot of manual effort. A prototype has been developed in this study to allow the consumers to locate such prospective shops based on advertisements in newspapers. This solution has a two-pronged approach. First, all the offers advertised in the newspaper are pre-processed and text extraction is performed using a ML algorithm named Tesseract OCR. Second the location of shops is collected and stored in a geodatabase. Finally, the advertisement is matched to the respective geo-located shop based on its name and location. Further based on the location of the consumer and his purchase choice, shops offering discounts are shown on a web based map. This prototype provides the consumer, a platform for geo-discovery of establishments of interest through the clutter of unrelated endorsements, by the use of Open Source GIS, Python programming and ML techniques

3C → 1H transfer of light-induced hyperpolarization allows for selective detection of protons in frozen photosynthetic reaction center

C labeled RCs from the purple bacteria of Rhodobacter sphaeroides. We observed response from the protons belonging to the photochemically active cofactors in their native protein environment. Such an approach is a potential heteronuclear spin-torch experiment which could be complementary to the classical heteronuclear correlation (HETCOR) experiments for mapping proton chemical shifts of photosynthetic cofactors and to understand the role of the proton pool around the electron donors in the electron transfer process occurring during photosynthesis.Solid state NMR/Biophysical Organic Chemistr
