Green synthesis, characterization and anticancer potential of platinum nanoparticles Bioplatin
Yogesh Bendale,Vineeta Bendale
Zhong Xi Yi Jie He Xue Bao , 2012,
Abstract: OBJECTIVE: In the present study, the anticancer potential of platinum nanoparticles Bioplatin is explored and the mode of interactions of Bioplatin with calf thymus DNA and honey was analyzed.METHODS: Bioplatin was synthesized with the help of green nanotechnology and characterized by particle size, zeta potential and surface morphology. The interaction of Bioplatin with DNA and honey was also checked with the help of circular dichroism spectroscopy and Fourier-transform infrared spectroscopy, respectively. The anticancer potential of Bioplatin was evaluated on peripheral blood mononuclear cells and A375 cells in vitro by analyzing results of MTT (3-(4,5)-dimethylthiahiazo-(-z-y1)-3,5-di-phenytetrazoliumromide), fluorescence microscopic studies and DNA fragmentation assay.RESULTS: Bioplatin exhibited a small particle size of 137.5 nm and a surface charge of -35.8 mV. Bioplatin interacted with DNA and brought in effective changes in structure and conformation of DNA, and formed a new complex that increased its stability of DNA intercalated with the base pair of DNA. In vitro studies demonstrated that Bioplatin arrested cell proliferation, and induced chromatin condensation and internucleosomal DNA fragmentation.CONCLUSION: Bioplatin induces apoptosis in cancer cells and may have some beneficial effect against human carcinoma. It interacts with DNA, brings stabilization to DNA, and thus prevents the replication of DNA.
Towards Open Set Deep Networks

Computer Science , 2015,
Abstract: Deep networks have produced significant gains for various visual recognition problems, leading to high impact academic and commercial applications. Recent work in deep networks highlighted that it is easy to generate images that humans would never classify as a particular object class, yet networks classify such images high confidence as that given class - deep network are easily fooled with images humans do not consider meaningful. The closed set nature of deep networks forces them to choose from one of the known classes leading to such artifacts. Recognition in the real world is open set, i.e. the recognition system should reject unknown/unseen classes at test time. We present a methodology to adapt deep networks for open set recognition, by introducing a new model layer, OpenMax, which estimates the probability of an input being from an unknown class. A key element of estimating the unknown probability is adapting Meta-Recognition concepts to the activation patterns in the penultimate layer of the network. OpenMax allows rejection of "fooling" and unrelated open set images presented to the system; OpenMax greatly reduces the number of obvious errors made by a deep network. We prove that the OpenMax concept provides bounded open space risk, thereby formally providing an open set recognition solution. We evaluate the resulting open set deep networks using pre-trained networks from the Caffe Model-zoo on ImageNet 2012 validation data, and thousands of fooling and open set images. The proposed OpenMax model significantly outperforms open set recognition accuracy of basic deep networks as well as deep networks with thresholding of SoftMax probabilities.
Towards Open World Recognition
Abhijit Bendale,Terrance Boult
Computer Science , 2014, DOI: 10.1109/CVPR.2015.7298799
Abstract: With the of advent rich classification models and high computational power visual recognition systems have found many operational applications. Recognition in the real world poses multiple challenges that are not apparent in controlled lab environments. The datasets are dynamic and novel categories must be continuously detected and then added. At prediction time, a trained system has to deal with myriad unseen categories. Operational systems require minimum down time, even to learn. To handle these operational issues, we present the problem of Open World recognition and formally define it. We prove that thresholding sums of monotonically decreasing functions of distances in linearly transformed feature space can balance "open space risk" and empirical risk. Our theory extends existing algorithms for open world recognition. We present a protocol for evaluation of open world recognition systems. We present the Nearest Non-Outlier (NNO) algorithm which evolves model efficiently, adding object categories incrementally while detecting outliers and managing open space risk. We perform experiments on the ImageNet dataset with 1.2M+ images to validate the effectiveness of our method on large scale visual recognition tasks. NNO consistently yields superior results on open world recognition.

Journal of Biomaterials and Nanobiotechnology (JBNB) , 2012, DOI: 10.4236/jbnb.2012.322039
Abstract: Nanotechnology has emerged as a boon to the society with immense potential in varied area of research and our day-to-day life. The application of nanotechnology for the advancement of biosensor leads to an efficient nanobiosensor with miniature structure as compared to conventional biosensors. Nanobiosensors can be effectively used for sensing a wide variety of fertilizers, herbicide, pesticide, insecticide, pathogens, moisture, and soil pH. Taken together, proper and controlled use of nanobiosensor can support sustainable agriculture for enhancing crop productivity.

Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.54026
Abstract:

Introduction: Ectopic pregnancy is an emergency in obstetric wards and a significant cause of maternal morbidity and mortality. Incidences of ectopic pregnancy are increasing. Life can be saved with quickness and alertness. Objective: The objective of this study is to find out and evaluate the incidence, clinical presentation, risk factors, and management outcomes of ectopic pregnancies at Sri Guru Ram Rai Institute of Medical and Health Sciences (SGRRIMHS), Dehradun, Uttarakhand, India. Method: We did a retrospective study of the patients admitted in our hospital (SMI Hospital, SGRRIMHS) and study period was January 1, 2004 to December 31, 2013. Medical records were studied for management, total admission in obstetric wards, total births. Data were collected with the aid of data-entry forms designed for study. There were 4040 ANC patients admitted, out of which 202 cases were ectopic pregnancies. The relevant data collected were analyzed with SPSS for Windows. Result: Ectopic pregnancy constituted 5.0% of all ANC cases admitted in our Hospital. The mean age of patients was 25±2 years, 192 of 202 (95.04%) had ruptured pregnancies, and remaining 10 (4.96%) were unruptured. The commonest clinical presentation was abdominal pain (162 of 20280.19%). The commonest (120 of 202, 59.4%) cause was past history of induced abortion. 4 deaths (1.98%) were recorded. Conclusion: Ecotopic pregnancy is common and recognized cause of maternal morbidity and mortality. It is a recognized risk of induced abortion.

Indian Journal of Dermatology , 2007,
Abstract: Background: Skin diseases are common in childhood and they are common reasons for pediatric visits to the hospital. In spite of this high occurrence, there are very few prospective studies addressing this issue. Aims: The present study was directed at determining the spectrum of dermato-pathological lesions encountered in a large general tertiary care hospital, over a two-year period. Materials and Methods: 107 cases formed the total sample studied, in a part prospective and part retrospective study. A detailed clinical history was recorded on a proforma prepared for the purpose and gross photographs were taken wherever possible. Results: Skin biopsies accounted for 7.29% of the total surgical pathology load, 55.44% of the total pediatric biopsies and 10.82% of the total number of skin biopsies. The age and sex distribution pattern revealed that the maximum number of biopsies (62.61%) were of older children, with a male preponderance (57.94%). The anatomic distribution pattern indicated predominant involvement of the limbs (59.82%). The maximum numbers of cases were of infectious nature (24.29%); the most frequently encountered being borderline tuberculoid Hansen′s disease (8.4%). A positive correlation with the clinical diagnosis was obtained in 56.07% cases. Conclusions: Histopathology contributed to the diagnosis in a significant number of (82.23%) cases, indicating its importance and utility.
