2Update on pathology of retinoblastoma显示文摘Retinoblastoma is caused by mutational inactivation of both alleles of the RB1 gene, which maps to chromosome 13 q14 and encodes retinoblastoma protein that acts as a tumor suppressor. Histopathological high-risk features of retinoblastoma are predictive of metastasis or local recurrence. The focus of this update is to emphasize the recent advances in pathology, various molecular key pathways and genome wide approaches for newer potential therapeutic future targets associated with retinoblastoma tumor biology. This review article highlights the new biomarkers expressed by the retinoblastoma tumor for the better survival of patients.Lata Singh Seema Kashyap 2018International Journal of Ophthalmology(English edition)2018,11,12:5
3Extraocular retinoblastoma in Indian children:clinical,imaging and histopathological features显示文摘AIM:To study eyes with extraocular dissemination(EORB),with the following aims:first to establish the mean lag period and to understand various reasons for delayed presentation,second to study their imaging profiles and third to analyze histopathological features of eyes enucleated after neoadjuvant chemotherapy.·METHODS:Prospective study of clinical and imaging features of EORBs(stage Ⅲ and Ⅳ International Retinoblastoma Staging System) presenting to a tertiary eye care centre.Histopathological features of eyes enucleated after receiving neoadjuvant chemotherapy were analyzed.A pictorial illustration of the varied imaging profile of EORB was also presented.·RESULTS:Over a period of one year,97 eyes were diagnosed with retinoblastoma;32 children(36 eyes)(37.1%) had EORB.Mean age 3.6±1.9 years,71.9% males,71.9% unilateral,3.1% with positive family history and40.6% with metastasis.On imaging,there was extrascleral involvement in 22.2%,involvement of orbital part of optic nerve in 33.3%,involvement of central nervous system in 27.8% and orbital wall involvement in2.9% eyes.On histopathological analysis of eyesenucleated after neoadjuvant chemotherapy,25.0% had no residual viable tumour tissue and rest all tumours were poorly differentiated.·CONCLUSION:There are very few human malignancies where definitive treatment is started without any confirmed histopathological diagnosis and imaging plays an important role in diagnosis and appropriate staging of the disease.Chemotherapy has a variable effect on EORB,75.0% of eyes with EORB had residual viable tumour tissue when enucleated after receiving neoadjuvant chemotherapy.Sumita Sethi Neelam Pushker Seema Kashyap Sanjay Sharma Mridula Mehta Sameer Bakhshi Saurbhi Khurana Supriyo Ghose 2013International Journal of Ophthalmology(English edition)2013,6,4:5
4Measuring turbulence in a circulating fluidized bed using PIV techniques显示文摘This study utilized the particle image velocimetry (PIV) technique, non-invasively near the wall, in the developing region, for the measurements of laminar and turbulent properties during circulation of Geldart B type particles in the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) riser. A novel method was used to measure axial and radial laminar and turbulent solids dispersion coefficients using autocorrelation technique. The instantaneous and hydrodynamic velocities for the solid phase were measured simultaneously in the axial and radial directions using a CCD camera, with the help of a colored rotating transparency. The measured properties, such as laminar and Reynolds stresses, laminar and turbulent granular tempera- tures, laminar and turbulent dispersion coefficients and energy spectra exhibited anisotropy. The mixing in the riser was on the level of clusters. The total granular temperatures were in reasonable agreement with the literature values. However, the axial and radial solids dispersion coefficients measured near the wall were slightly lower than the radially averaged values in the literature.Mayank Kashyap Benjapon Chalermsinsuwan Dimitri Gidaspow 2011Particuology2011,9,6:5
5Checklist for early recognition and treatment of acute illness:International collaboration to improve critica care practice显示文摘Processes to ensure world-wide best-practice for critical care delivery is likely to minimize preventable death, disability and costly complications for any healthcare system's sickest patients, but no large-scale efforts have so far been undertaken towards these goals. The advances in medical informatics and human factors engineering have provided possibility for novel and user-friendly clinical decision support tools that can be applied in a complex and busy hospital setting. To facilitate timely and accurate best-practice delivery in critically ill patients international group of intensive care unit(ICU) physicians and researchers developed a simple decision support tool: Checklist for Early Recognition and Treatment of Acute Illness(CERTAIN). The tool has been refined and tested in high fidelity simulated clinical environment and has been shown to improve performance of clinical providers faced with simulated emergencies. The aim of this international educational intervention is to implement CERTAIN into clinical practice in hospital settings with variable resources(included those in low income countries) and evaluate the impact of the tool on the care processes and patient outcomes. To accomplish our aims, CERTAIN will be uniformly available on either mobile or fixed computing devices(as well as a backup paper version) and applied in a standardized manner in the ICUs of diverse hospitals. To ensure the effectiveness of the proposed intervention, access to CERTAIN is coupled with structured training of bedside ICU providers.Marija Vukoja Rahul Kashyap Srdjan Gavrilovic Yue Dong Oguz Kilickaya Ognjen Gajic 2015World Journal of Critical Care Medicine2015,4,1:5

7An Effective Density Based Approach to Detect Complex Data Clusters Using Notion of Neighborhood Difference显示文摘The density based notion for clustering approach is used widely due to its easy implementation and ability to detect arbitrary shaped clusters in the presence of noisy data points without requiring prior knowledge of the number of clusters to be identified. Density-based spatial clustering of applications with noise(DBSCAN) is the first algorithm proposed in the literature that uses density based notion for cluster detection. Since most of the real data set, today contains feature space of adjacent nested clusters,clearly DBSCAN is not suitable to detect variable adjacent density clusters due to the use of global density parameter neighborhood radius N_(rad) and minimum number of points in neighborhood N_(pts). So the efficiency of DBSCAN depends on these initial parameter settings, for DBSCAN to work properly, the neighborhood radius must be less than the distance between two clusters otherwise algorithm merges two clusters and detects them as a single cluster. Through this paper: 1) We have proposed improved version of DBSCAN algorithm to detect clusters of varying density adjacent clusters by using the concept of neighborhood difference and using the notion of density based approach without introducing much additional computational complexity to original DBSCAN algorithm.2) We validated our experimental results using one of our authors recently proposed space density indexing(SDI) internal cluster measure to demonstrate the quality of proposed clustering method. Also our experimental results suggested that proposed method is effective in detecting variable density adjacent nested clusters.S.

8Isolation, serotype diversity and antibiogram of Salmonella enterica isolated from different species of poultry in India显示文摘Objective: To study the occurrence and serotype diversity of Salmonella isolates in different species of poultry(chicken, emu and duck) and determine their resistance pattern against various antibiotics of different classes.Methods: About 507 samples comprising 202 caecal contents and 305 fecal samples from chicken, emu and duck were processed for isolation of Salmonella enterica. Salmonellae were isolated and detected by standard protocol of ISO 6579 Amendment 1: Annex D. Genetic confirmation was also made by using 16 S r RNA genus specific PCR. Serotype specific PCR was also done to detect the most common serovars viz. Salmonella Enteritidis, Salmonella Typhimurium and Salmonella Gallinarum. All obtained isolates were subjected to a set of 25 antibiotics to study their antibiogram by using Baeur-Kirby disk diffusion method.Results: Out of 507 samples processed, 32 isolates of Salmonella enterica(18 from caecal contents and 14 from faecal samples) were obtained, of which 24 belonged to 6 different serovars, 6 were untypeable and 2 were rough strains. Salmonella Enteritidis was the most predominant serotype(9), followed by Salmonella Typhimurium(5), Salmonella Virchow(4), Salmonella Gallinarum(3), Salmonella Reading(2) and Salmonella Altona(1). Antibiotic resistance pattern was maximum(100%) to oxacillin, penicillin and clindamycin, followed by ampicillin(68.75%), tetracycline(65.62%), nalidixic acid(56.25%) and colistin(46.87%). High sensitivity of isolates was recorded for chloramphenicol(96.87%) followed by meropenem(84.37%). Conclusions: Occurrence of high proportion of serovars in our study which can cause serious gastroenteritis in humans is a matter of concern. Salmonella Altona has been detected for the first time in India from poultry. This serotype is known to cause serious outbreaks of gastroenteritis in humans. Multidrug resistant isolates were recovered at high percentage which can be attributed to non-judicious use of antibiotics both in prophylaxis and treatment regimen. This observation draws serious attention as poultry serves as an important source of transmission of these multidrug resistant Salmonella serovars to humans.Irfan Ahmad Mir Sudhir Kumar Kashyap Sunil Maherchandani 2015Asian Pacific Journal of Tropical Biomedicine2015,5,7:3
9Congenital diarrhea in a newborn infant: A case report显示文摘BACKGROUND Microvillus inclusion disease(MVID)is a rare autosomal recessive cause of severe congenital diarrhea with significant morbidity and mortality.Definitive treatment involves bowel transplant.The diagnosis of this condition can be challenging and a few genetic panels are available for the identification of the most common mutations.We present the case of an infant with MVID due to a mutation not reported in the literature before.CASE SUMMARY We report the case of an infant transferred to our institution with severe diarrhea of unknown etiology,failure to thrive,and significant metabolic derangements.An extensive work-up including stool studies for common gastrointestinal pathogens,abdominal ultrasound,esophagogastroduodenoscopy with duodenal biopsy and flexible sigmoidoscopy failed to reveal a diagnosis.Multiple dietary and formula regimens were introduced but all resulted in voluminous diarrhea.She remained on total parenteral nutrition(TPN)for the duration of her hospital stay.Genetic testing was done and she was subsequently found to have a novel mutation in the MYO5B gene[homozygous mutation for MYO5B c.1462del,p.(Ile488Leufs*93)]giving us the diagnosis of MVID.She remains on TPN while awaiting bowel transplant at the time of the compilation of this case report.CONCLUSION We report a novel mutation involved in MVID and highlight the importance of considering this disease when faced with a newborn presenting with life threatening diarrhea.At the time of this publication,232 allelic variations of this gene(MIM#606540)exist in National Center for Biotechnology Information’s database.Our patient’s mutation has not been reported in literature as a cause of MVID.Mehrin Sadiq Omer Choudry Arun K Kashyap Danitza M Velazquez 2019World Journal of Clinical Pediatrics2019,8,3:3
