Temporary Upper Limb AIIMS Prostheses - A New Design
Nallegowda M,Singh U,Khanna M,Babbar A
Indian Journal of Physical Medicine and Rehabilitation , 2010,
Abstract: Amputation of upper limb causes immediate disturbancein the body image during postoperative period. Early fittingof the prosthesis helps to incorporate the prosthesis inthe body image, reduction of stump edema, stump pain,promotion of two-handed activities, prevention of musclewasting, scoliosis and more acceptance of permanentprosthesis. First four to six weeks of post-operative periodare considered to be the golden period to achieve bettersuccess in upper limb amputee rehabilitation. Not muchhas been done in the field of upper limb temporaryprosthesis in the last twenty five years. To address thisgap a new temporary upper limb prosthesis was designedand fitted to six patients. The design is simple, low costand functional. It can be fitted immediately after surgery.It is also helpful in cases with open wounds and stumpneuromas.
Robot-assisted urologic surgery in 2010 - Advancements and future outlook
Babbar Paurush,Hemal Ashok
Urology Annals , 2011,
Abstract: Robotic surgery is a cutting edge and minimally invasive procedure, which has generated a great deal of excitement in the urologic community. While there has been much advancement in this emerging technology, it is safe to say that robotic urologic surgery holds tremendous potential for progress in the near future. Hence, it is paramount that urologists stay up-to-date regarding new developments in the realm of robotics with respect to novel applications, limitations and opportunities for incorporation into their practice. Robot-assisted surgery provides an enhanced 3D view, increased magnification of the surgical field, better manual dexterity, relatively bloodless field, elimination of surgeon′s tremor, reduction in a surgeon′s fatigue and mitigation of scattered light. All these factors translate into greater precision of surgical dissection, which is imperative in providing better intraoperative and postoperative outcomes. Pioneering work assessing the feasibility of robotic surgery in urology began in the early 2000′s with robot-assisted radical prostatectomy and has since expanded to procedures such as robot-assisted radical cystectomy, robot-assisted partial nephrectomy, robot-assisted nephroureterectomy and robot-assisted pyeloplasty. A MEDLINE search was used to identify recent articles (within the last two years) and publications of specific importance, which highlighted the recent developments and future direction of robotics. This review will use the aforementioned urologic surgeries as vehicles to evaluate the current status and future role of robotics in the advancement of the field of urology.
On the Use of Landsat-5 TM Satellite for Assimilating Water Temperature Observations in 3D Hydrodynamic Model of Small Inland Reservoir in Midwestern US  [PDF]

Advances in Remote Sensing (ARS) , 2013, DOI: 10.4236/ars.2013.23024
Abstract:

Accuracy of hydrodynamic and water quality numerical models developed for a specific site is dependent on multiple model parameters and variables whose values are attained via calibration processes and/or expert knowledge. Real time variations in the actual aquatic system at a site necessitate continuous monitoring of the system so that model parameters and variables are regularly updated to reflect accurate conditions. Multiple sources of observations can help adjust the model better by providing benefits of individual monitoring technology within the model updating process. For example, remote sensing data provide a spatially dense dataset of model variables at the surface of a water body, while in-situ monitoring technologies can provide data at multiple depths and at more frequent time intervals than remote sensing technologies. This research aims to present an overview of an integrated modeling and data assimilation framework that combines three-dimensional numerical model with multiple sources of observations to simulate water column temperature in a eutrophic reservoir in central Indiana. A variational data assimilation approach is investigated for incorporating spatially continuous remote sensing temperature observations and spatially discrete in-situ observations to change initial conditions of the numerical model. The results demonstrate the challenges in improving the model performance by incorporating water temperature from multi-spectral remote sensing analysis versus in-situ measurements. For example, at a eutrophic reservoir in Central Indiana where four images of multi-spectral remote sensing data were assimilated in the numerical model, the overall error for the four images reduced from 20.9% (before assimilation) to 15.9% (best alternative after the assimilation). Additionally, best improvements in errors were observed on days closer to the starting time of model’s assimilation time window. However, when the original and updated model results for the water column temperature were compared to the in-situ measurements during the data assimilation period, the error was found to have actually increased from 1.8 (before assimilation) to 2.7

Abstract: Sheep chromosome 3 (Oar3) has the largest number of QTLs reported to be significantly associated with resistance to gastro-intestinal nematodes. This study aimed to identify single nucleotide polymorphisms (SNPs) within candidate genes located in sheep chromosome 3 as well as genes involved in major immune pathways. A total of 41 SNPs were identified across 38 candidate genes in a panel of unrelated sheep and genotyped in 713 animals belonging to 22 breeds across Asia, Europe and South America. The variations and evolution of immune pathway genes were assessed in sheep populations across these macro-environmental regions that significantly differ in the diversity and load of pathogens. The mean minor allele frequency (MAF) did not vary between Asian and European sheep reflecting the absence of ascertainment bias. Phylogenetic analysis revealed two major clusters with most of South Asian, South East Asian and South West Asian breeds clustering together while European and South American sheep breeds clustered together distinctly. Analysis of molecular variance revealed strong phylogeographic structure at loci located in immune pathway genes, unlike microsatellite and genome wide SNP markers. To understand the influence of natural selection processes, SNP loci located in chromosome 3 were utilized to reconstruct haplotypes, the diversity of which showed significant deviations from selective neutrality. Reduced Median network of reconstructed haplotypes showed balancing selection in force at these loci. Preliminary association of SNP genotypes with phenotypes recorded 42 days post challenge revealed significant differences (P<0.05) in fecal egg count, body weight change and packed cell volume at two, four and six SNP loci respectively. In conclusion, the present study reports strong phylogeographic structure and balancing selection operating at SNP loci located within immune pathway genes. Further, SNP loci identified in the study were found to have potential for future large scale association studies in naturally exposed sheep populations.

Abstract: Six loci, matK, rbcL, rpoB, rpoC1, trnH-psbA spacer from the chloroplast genome and ITS, from the nuclear genome, were compared for their amplification, sequencing and species discrimination success rates among multiple accessions of 36 Dendrobium species. The trnH-psbA spacer could not be considered for analysis as good quality sequences were not obtained with its forward primer. Among the tested loci, ITS, recommended by some as a possible barcode for plants, provided 100% species identification. Another locus, matK, also recommended as a universal barcode for plants, resolved 80.56% species. ITS remained the best even when sequences of investigated loci of additional Dendrobium species available on the NCBI GenBank (93, 33, 20, 18 and 17 of ITS, matK, rbcL, rpoB and rpoC1, respectively) were also considered for calculating the percent species resolution capabilities. The species discrimination of various combinations of the loci was also compared based on the 36 investigated species and additional 16 for which sequences of all the five loci were available on GenBank. Two-locus combination of matK+rbcL recommended by the Plant Working Group of Consortium for Barcoding of Life (CBOL) could discriminate 86.11% of 36 species. The species discriminating ability of this barcode was reduced to 80.77% when additional sequences available on NCBI were included in the analysis. Among the recommended combinations, the barcode based on three loci - matK, rpoB and rpoC1- resolved maximum number of species.Any recommended barcode based on the loci tested so far, is not likely to provide 100% species identification across the plant kingdom and thus is not likely to act as a universal barcode. It appears that barcodes, if based on single or limited locus(i), would be taxa specific as is exemplified by the success of ITS among Dendrobium species, though it may not be suitable for other plants because of the problems that are discussed.DNA barcoding is an emerging technology, which

Abstract: Developers typically measure a Web application’s quality of service in terms of response time, throughput, and availability. Poor QoS translates into frustrated customers, which can lead to bad opportunities. One way to assess IT infrastructure performance is through load testing, which assess how the website supports its expected workload by running specified set of scripts that emulate behavior at different load levels. This paper addresses the website performance analysis based on component load testing with different QoS measures.

Abstract: The aim of the present study was to evaluate the effects of partial sleep deprivation on the cognitive statusand alertness of medical students using auditory event related potential (ERP) and auditory reaction time(RT) using sleep questionnaire, Stanford Sleepiness Scale (SSS), auditory ERP (P300) and RT. Sleep timewas significantly shorter in the test condition as compared to the baseline values (p<0.001). Significantlyhigher values on the SSS (p<0.05) were found after sleep restriction. The P300 latency and amplitudesignificantly decreased (p<0.01 and p<0.001 respectively) when the test values were compared to thebaseline. RT also showed a significant decrease (p<0.001) in the test condition as compared to the baselinevalues. However, no significant correlation could be ascertained between SSS and P300 amplitude andlatency as well as RT. This study demonstrates that partial sleep deprivation produces variable effects onthe cognitive status of medical students as reflected by the decrease in P300 amplitude and latency.Alertness of medical students seemed to show an improvement as reflected by the decrease in RT.

Abstract: A fibroepithelial polyp (FEP) is a relatively uncommon benign condition of vulva, mainly of reactive origin, occurs in women of reproductive age, mostly during pregnancy. Here is a case which presented with bilateral vulval mass, for that she underwent surgical excision. Histopathological examination revealed bilateral fibroepithelial vulval polyp. After 4 years of uneventful interval same female came with term pregnancy with a huge vulval mass on left side, having similar characteristic features as previous one. Emergency cesarean section followed by excision of polyp in the same sitting done. Histopathological report confirmed the finding of fibroepithelial polyp this time also. Only few cases of recurrent fibroepithelial polyp of vulva associated with pregnancy have been reported till date. [Int J Reprod Contracept Obstet Gynecol 2013; 2(2.000): 245-247]
