Iris Recognition System

In a biometric system a person is identified automatically by processing the unique features that are posed by the individual. Iris Recognition is regarded as the most reliable and accurate biometric identification system available. In Iris Recognition a person is identified by the iris which is the part of eye using pattern matching or image processing using concepts of neural networks. The aim is to identify a person in real time, with high efficiency and accuracy by analysing the random patters visible within the iris if an eye from some distance, by implementing modified Canny edge detector algorithm. The major applications of this technology so far have been: substituting for passports (automated international border crossing); aviation security and controlling access to restricted areas at airports; database access and computer login.
FLT3 internal tandem duplication mutations in adult acute myeloid leukaemia define a high‐risk group

Genomic DNA from 106 cases of adult de novo acute myeloid leukaemia (AML) was screened by polymerase chain reaction (PCR) and gel electrophoresis for FLT3 internal tandem duplication (ITD) mutations within the juxtamembrane (JM) domain. FLT3 mutations were detected in 14 cases (13·2%) and occurred in FAB types M1 (4 out of 14 cases), M3 (1 out of 10 cases), M4 (5 out of 37 cases) and M5 (4 out of 11 cases). Sequence analysis of four cases with abnormal PCR electrophoretic patterns revealed in frame duplications in the region of exon 11 of between 27 and 111 base pairs. Three are predicted to result in the tandem duplication of adjacent amino acid residues and one to result in a tandem duplication plus insertion of a novel amino acid motif. Statistical analysis showed the FLT3 mutations to be a strong prognostic factor, with patients lacking the mutation surviving significantly longer from diagnosis (mean 29·1 months) than those with an ITD (mean 12·8 months; P = 0·0002). Thirteen of the 14 patients with FLT3 mutations died within 18 months of diagnosis. FLT3 mutations were of prognostic significance in good risk disease (P = 0·04), as well as in patients with standard risk disease (P = 0·0096). This study demonstrates that the FLT3 ITD mutation occurs in a significant percentage of adult AML cases and is an important adverse prognostic factor that appears independent of conventional karyotypic findings.
A detailed semiologic analysis of childhood psychogenic nonepileptic seizures

Purpose: Psychogenic nonepileptic seizure (PNES) is an important differential diagnostic problem in patients with or without epilepsy. There are many studies that have analyzed PNES in adults; currently, however, there is no systematic assessment of purely childhood PNES semiology. Our study based on a large pediatric video‐electroencephalography (EEG) monitoring (VEM) cohort, provides a detailed analysis of childhood PNES and assesses the usability of the current classification system described in adults.
Caring for Organ Donors: The Intensive Care Unit Nurses’ View

The nursing care for patients who are pronounced brain-dead but kept alive to serve as organ donors demands technical-scientific skills and the ability to handle situations that are often in conflict with the traditional concepts of nursing care. Based on the phenomenological approach in this article, essential themes of the lived experience of caring for these patients, including the technical and specific nursing care, the relationship with organ donors and their families, and the nurses’ perception of themselves in this professional situation are described. The results point to the contradictions and ambiguities of this type of nursing, especially in regards to the affective and philosophical aspects.
Instance, Evolution, and Predictive Modeling of Social Networks

Various phenomena within the information systems discipline can be studied using the social network paradigm that views social entities as nodes with links between them. The social network analysis (SNA) theory has applications in knowledge management, computer mediated communications, security informatics, and other domains. Challenges in SNA can be classified into three broad areas: instance modeling, evolution modeling, and predictive modeling. Instance modeling focuses on the study of static network properties, evolution modeling examines factors behind network growth, and predictive modeling is concerned with identification of hidden and future network links. This dissertation presents four essays that address these challenges with empirical studies in knowledge management and security informatics. The first essay on instance and evolution modeling contributes to SNA theory by examining a real-world network that contains interactions between thirty thousand individuals. The study is among the few that empirically examine large human-only networks and verify the presence of small-world properties and scale-free distributions. In addition, it proposes a novel application of a network evolution model to examine the growth of networks across geographical boundaries. The second essay on evolution modeling proposes a methodology to identify
The Effect of Closed-Eye Tear Film Conditions on Blood-Isolated Neutrophils, In Vitro

ABSTRACT Purpose: Eyelid closure results in influx of neutrophils onto the ocular surface, which are non-responsive to inflammatory stimuli. This investigation examined whether incubation of blood-isolated neutrophils in closed-eye conditions induce a tear-film neutrophil phenotype. Methods: Blood-isolated neutrophils were incubated combining various conditions: hypoxia, corneal epithelial cells (HCEC), artificial tear solution (ATS). Results: A hypoxic environment induced no differential effect on membrane receptor expression. Incubation in the presence of HCEC resulted in membrane receptor upregulation and increase in caspase activation. Conclusions: Hypoxia, corneal epithelial cell exposure, or artificial tear fluid are insufficient to replicate a tear-film neutrophil phenotype using blood-isolated neutrophils.

Are Nurses Recognizing Delirium ?

Recognizing Delirium? A Systematic Review Thirty-eight percent of all hospital inpatients in the United States in 2005 were older than age 65 (DeFrances & Hall, 2007). The prevalence of delirium on hospital admission has been reported from 14% to 24%, whereas the incidence has been documented from 6% to 56% (Agostini & Inouye, 2003; Inouye, 1998). Thus, delirium is a prevalent, costly, and global problem in older adults. According to the American Psychiatric Association (APA) (2000), delirium has four components:
Investigating the Moderating and Mediating Effects of Dysfunctional Attitudes and Self-Esteem on the Relationship between Social Support and Depression among Late Adolescents in Klang Valley Malaysia: A Moderated Mediation Model

Seeing that the interdependence between adolescent depression and impairments in psychosocial functioning is conspicuous and evident, scrutiny on social support and cognition is a sine qua non of stimulating the psychological well-being amongst adolescents, expressly those in the stage of late adolescence who are discerned at higher risk of getting depressed. Hence, the moderated mediation model in the present investigation has been instigated to appraise the moderating and mediating effects of dysfunctional attitudes and self-esteem on the one-way relationship between social support and depression in late adolescence. Prior to this inspection, a pilot test has already been orchestrated to examine and ensure satisfactory psychometric properties of the assessment tool employed. A set of questionnaire encompassing self-report Interpersonal Support Evaluation List, Dysfunctional Attitudes Scale, Rosenberg's Self-Esteem Scale and Beck Depression Inventory were manoeuvred in a sample of 522 late adolescents taken from two local secondary schools and a university in Klang Valley, Malaysia. By way of implementing a series of multivariate analyses, the study divulged that self-esteem has noteworthily played its role of moderating the predictive relationship between social support and depression which mediated by dysfunctional attitudes in the samples, whereas the moderating effect of dysfunctional attitudes on the relationship among social support, self-esteem and depression has been insignificant, showing that dysfunctional attitudes is a remarkably consistent mediator in the one-way relationship between social support and depression moderated by self-esteem. Following the research findings, discussion has been carried out to elucidate the phenomenon.
Study of Variant Posterior Cerebral Circulation and its Clinical Relevance

The cerebral blood flow is divided into an anterior circulation and a posterior circulation connected to each other in the form of a circle called Circle of Willis (CW). It is formed by the unification of the internal carotid (ICA) and vertebrobasilar systems Posteriorly, the basilar artery, formed by the left and right vertebral arteries, branches into a left and right posterior cerebral artery (PCA), forming the posterior circulation. The internal carotid system lies anteriorly and is joined to the posterior circulation by posterior communicating (PCoA) arteries. The internal carotid artery divides into anterior and middle cerebral artery. The two anterior cerebral arteries are joined to each other by an anterior communicating artery. The posterior cerebral artery before it joins the posterior communicating artery that means its proximal part is named as the pre communicating part (P1) and the distal part as the post communicating part (P2). In the adult P1 has a diameter larger than the PCoA so that the occipital lobe gets its blood supply mainly via the vertebrobasilar system whereas in the fetus the diameter of the ipsilateral precommunicating (P1) segment of PCA is less than the diameter of PCoA, so that the blood supply to [1] the occipital lobe is mainly via the internal carotid arteries. In some persons, there is a transitional configuration in which the PCoA is equal in diameter to the P1 segment of the PCA. These variations can cause complications if thrombotic material present in atherosclerotic plaques of ICA gets dislodged into PCA through a PCoA which has a larger diameter. In the present study, the configuration of posterior cerebral circulation and its clinical relevance was studied in 40 human brains in the department of anatomy at KJSMC. Adult Type PCA was found in 60% of the specimens studied, Fetal Type PCA was found in 12.5% of the specimens, Transitional Type PCA was found in 25% of the specimens and a combination of Adult and Transitional Type was found in 2.5% of the specimens.
Performance of binary antipodal signaling over indoor UWB MIMO channel

We generalize a suitable, known indoor UWB SISO channel model to obtain a new discrete-time model for the indoor UWB MIMO radio channel. The properties and potential benefits arising from the channels specific correlation features benefits arising form the channels specific correlation features are investigated by means of simulations. We chow that the indoor UWB channel can offer much lower ISI than would be expected for a given rms delay spread, and confirm that systems operating on this channel require a small-scale fading margin of only a few dB. It is further demonstrated that an uncoded MIMO communication scheme applied to the UWB channel can offer superior SVEP performance compared to its use on the i.i. d. Rayleigh flat fading channel. Moreover, it was found that such an UWB scheme can offer very low SVEP with several transmitting and only a single receiving antenna (MISO), in contrast to a similar narrowband system.
Liver proteome analysis of adaptive response in rat immediately after partial hepatectomy

The extraordinary ability of the liver to regenerate after resection continues to be an important fascination to mammalian liver researchers. However, at present, there are still several central questions regarding the process of liver regeneration that are not clear. In our study, we try to clarify how the liver is able to maintain its functions as well as to initiate liver regeneration after a significant loss of two‐thirds. Here differentially expressed proteins in rat livers at 1 h after partial hepatectomy (PHx) and sham operation were analyzed using 2‐DE combined with MALDI‐TOF/TOF MS. After the analysis, 24 significantly changed spots (ratio≥2, p<0.05) were identified. Those proteins are involved in important liver functions such as metabolism, detoxification, and inflammation. Based on the changes in the protein levels found in our data, we identified two aspects of remnant liver immediately after PHx, which focused on the hepatic adaptation and the inflammatory response associated with the initiation of liver regeneration after PHx. For the first time, the differential expression of pyruvate dehydrogenase complex (PDHX), paraoxonase 1 (PON1), thyroid hormone receptor β, GAP43 (where GAP stands for growth‐associated protein), and interleukin‐2 (IL2), after PHx, were validated by Western blot.
Laparoscopic versus open ileocolic resection for Crohn's disease.

OBJECTIVE Laparoscopic ileocolic (LI) resection for Crohn's disease has several potential advantages over the traditional open technique. The objective of this study was to compare early surgical outcomes in patients having laparoscopic versus open ileocolic resections for Crohn's disease. METHODS Data collected prospectively from 21 patients having LI resection for Crohn's disease between 1995 and 2001 were compared to data from 19 patients having open ileocolic resection for Crohn's disease between 1990 and 1995. RESULTS Patients in both groups had similar ages, sex distribution, and rates of previous abdominal surgery. Mean operating time was not significantly different between the groups. There was a nonsignificant trend to less postoperative analgesic requirement in the laparoscopic group. Resumption of liquid (P <.001) and solid (P =.01) diet, return of bowel function [flatus (P =.008), feces (P =.008)] and time to discharge (P =.001) all occurred significantly more quickly in the laparoscopic group. There was no difference in the rates of morbidity between the two groups. CONCLUSIONS LI resection for Crohn's disease appears to be safe and has comparable if not superior results to open surgery in the short term.
Nasal Nitric Oxide: A Comparison of Measurement Techniques

Nasal nitric oxide measurement may be a surrogate marker of upper airway inflammation. There is, however, no standardized measurement technique; and this led us to examine measurement techniques for acceptability and reproducibility. In five subjects we examined the flow dependence of nasal NO. In 13 healthy volunteers, nasal NO was measured on-line by five methods: 1) Tidal nasal and oral breathing: NO sampling during exclusive nasal followed by exclusive oral tidal breathing; 2) Fixed flow exhalation: NO sampling during exclusive nasal followed by exclusive oral exhalation at 100 mL/second from total lung capacity; 3) Nasal-oral aspiration: air aspirated from the mouth via both nares at 100 mL/second with glottis closure; 4) Aspiration from one nares: air aspirated from one nares at 3.3 mL/second using nitric oxide analyzer sample line with velum closure; 5) Nasal Insufflation: NO sampled at one nares as air insufflated into the other nares at a flow of 100 mL/second with velum closure. Acceptability of all methods was assessed by subjects and technicians. Nasal NO concentration showed a significant inverse correlation with transnasal flow rate. All methods showed excellent reproducibility as assessed by the intraclass correlation coefficient except tidal breathing, which showed highly variable breath-to-breath NO levels, although mean breath values were reproducible. Mean nasal NO concentrations with methods 1, 2, 3, 4, and 5 were 32.1, 50.2, 62.8, 1381, and 60.0 ppb, respectively. Velum closure was not always achieved in methods 4 and 5, whereas methods 1 and 2 required separate nasal and oral procedures. Method 5 had reduced acceptability. NO concentrations were similar with methods that used the same airflow (2, 3, and 5). Nasal NO can be sampled in different ways with excellent reproducibility. In view of the flow dependence of nasal NO, it is vital to use a constant flow rate, and lower airway NO contribution must be excluded or subtracted. The fixed flow exhalation appears to be the preferred method as it is highly reproducible and acceptable.
Subject knowledge improves interactive query expansion assisted by a thesaurus

This study explores how experts and novices in pedagogics expanded queries supported by the ERIC thesaurus, and how this was connected to the search effectiveness in an easy and a difficult search task. The expert group consisted of 15 undergraduates in pedagogy and the novice group of 15 students with no previous studies in this field. Their search logs were recorded and a pre‐ and post‐search interview was conducted. The results show that the number and type of terms selected from the thesaurus for expansion by experts improved search effectiveness, whereas there were no connections between the use of thesaurus and improvement of effectiveness among novices. The effectiveness of expansions varied between the facets of the queries. Thus, a vital condition for benefiting from a thesaurus in query expansion to improve search results is sufficient familiarity with the search topic. The results suggest also that it is not in the first place the number of terms used in expansion, but their type and quality that are crucial for search success.
Water Use and Drought Response in Cultivated and Wild Apples

Water availability is the single most important factor determining plant survival. Many environments experience water-limited periods of various degrees and duration. The issue of water availability for agricultural crops where maintenance of high yields over variable growing seasons is desirable is particular critical. For plants, the strategy choices for survival can be summarized as dehydration avoidance (e.g., deep rooting), dehydration tolerance (e.g., accumulation of osmoprotectants) and drought escape (e.g., reproductive completion before the dry season). Drought adaptation in most plants is controlled by complicated interactions between anatomy, physiology and biochemistry, all of which are directly or indirectly under genetic control [1-3].
Subclinical depression in Urban Indian adolescents: Prevalence, felt needs, and correlates

Background: Subclinical depression in adolescents constitutes a risk factor for future clinical depression and hence warrants examination. However, there is a paucity of research that documents subclinical depression among adolescents in India. Objectives: (a) To investigate the prevalence of subclinical depression in urban school-going adolescents; (b) to investigate the problems and felt needs of these adolescents; (c) to examine depression-related variables; and (d) to examine the relationships between socio-demographic and depression-related variables. Materials and Methods: Eight hundred adolescents (ages 13–18 years) of English-medium schools of Bangalore city were assessed using standardized self-report measures. Results: Academic difficulties were the most frequently reported problem, followed by interpersonal issues. Of the sample, 18% adolescents were identified as endorsing subclinical depression. Adolescents in the present study scored higher on measures of depression and negative cognitions than their Western counterparts. In addition, girls were found to be at higher risk for experiencing depressive symptoms and negative cognitions, lower social problem-solving skills, and more problematic interpersonal relationships as compared to boys. Conclusion: Identification of subclinical depression constitutes an important goal, as it places an adolescent at risk of considerable vulnerability and impairment.
Automatic digital restoration of color faded images and motion films

In this work, a novel approach for restoration of Color faded images is presented. A Uniform fading model is assumed. The algorithm comprises of matching the blocks in the image with some predefined reference blocks. These reference blocks are used to represent the true color of objects. The Correlation Coefficient is used as a measure for similarity matching. The threshold used for determining the matching is chosen adaptively from the image itself. A fade detection algorithm is proposed for distinguishing color faded images from the images with true cast. The algorithm has been tested and validated over a number of image sequences.
Prevention of mother-to-child transmission and voluntary counseling and testing programme data: what is their utility for HIV surveillance?

Objective:Antenatal clinic (ANC)-based surveillance through unlinked anonymous testing (UAT) for HIV without informed consent provides solid long-term trend data in resource-constrained countries with generalized epidemics. The rapid expansion of the prevention of mother-to-child transmission (PMTCT) and voluntary counseling and testing (VCT) programmes prompts the question regarding their utility for HIV surveillance and their potential to replace UAT-based ANC surveillance. Methods:Four presentations on the use of PMTCT or VCT data for HIV surveillance were presented at a recent international conference. The main findings are presented in this paper, and the operational and epidemiological aspects of using PMTCT or VCT data for surveillance are considered. Results:VCT data in Uganda confirm the falling trend in HIV prevalence observed in ANC surveillance. Thailand, a country with nationwide PMTCT coverage and a very high acceptance of HIV testing, has replaced UAT data in favor of PMTCT data for surveillance. Studies from Botswana and Kenya showed that PMTCT-based HIV prevalences was similar, but the quality and availability of the PMTCT data varied. Conclusion:The strength of UAT lies in the absence of selection bias and the availability of individual data. Conversely, the quantity of VCT and PMTCT programme testing data often exceed those in UAT, but may be subject to bias due to self-selection or test refusal. When using VCT or PMTCT data for surveillance, investigators must consider these caveats, as well as their varying data quality, accessibility, and availability of individual records.
CALCIFICATION OF A HYDROPHILIC ACRYLIC INTRAOCULAR LENS AFTER PARS PLANA VITRECTOMY

Purpose: Anterior surface calcification of a hydrophilic acrylic intraocular lens (IOL) associated with iatrogenic exposure of air after an uncomplicated pars plana vitrectomy is described. Methods: The clinical and histochemical findings of a patient who developed postoperative opacification of a hydrophilic acrylic intraocular lens are retrospectively reviewed. Results: A 63-year-old woman developed fine granular opacifications on the anterior surface of the intraocular lens 8 months after a pars plana vitrectomy with iatrogenic exposure of air. The intraocular lens was explanted and histochemical analysis confirmed the presence of calcium. Conclusion: Physicians should be aware of this complication and be cautious about the use of intraocular gas in either the front or the back of the eye in patients with hydrophilic acrylic intraocular lenses.
