Studies on the Antidiabetic Activities of Cordyceps militaris Extract in Diet-Streptozotocin-Induced Diabetic Sprague-Dawley Rats

Due to substantial morbidity and high complications, diabetes mellitus is considered as the third “killer” in the world. A search for alternative antidiabetic drugs from herbs or fungi is highly demanded. Our present study aims to investigate the antidiabetic activities of Cordyceps militaris on diet-streptozotocin-induced type 2 diabetes mellitus in rats. Diabetic rats were orally administered with water extract or alcohol extract at 0.05 g/kg and 2 g/kg for 3 weeks, and then, the factors levels related to blood glucose, lipid, free radicals, and even nephropathy were determined. Pathological alterations on liver and kidney were examined. Data showed that, similar to metformin, Cordyceps militaris extracts displayed a significant reduction in blood glucose levels by promoting glucose metabolism and strongly suppressed total cholesterol and triglycerides concentration in serum. Cordyceps militaris extracts exhibit antioxidative effects indicated by normalized superoxide dismutase and glutathione peroxidase levels. The inhibitory effects on blood urea nitrogen, creatinine, uric acid, and protein revealed the protection of Cordyceps militaris extracts against diabetic nephropathy, which was confirmed by pathological morphology reversion. Collectively, Cordyceps militaris extract, a safe pharmaceutical agent, presents excellent antidiabetic and antinephropathic activities and thus has great potential as a new source for diabetes treatment.
International Journal of Science and Technology a Novel Design of a Microstrip Patch Antenna with an Endfire Radiation for Sar Applications

The major disadvantage of microstrip antennas is its low gain and the rectangular or circular patch antennas do not have an endfire radiation. In this paper a design of microstrip antenna with four circular patches is presented. The model when simulated produces an endfire radiation and hence the gain can be increased in a particular direction. The proposed model is simulated using Ansoft HFSS software and various antenna parameters are measured. The antenna works at 5GHz where applications like synthetic aperture radar (SAR) are operated.
Evaluating the ChillFish Biofeedback Game with Children with ADHD

Breathing exercises have been shown to have multiple benefits for children with Attention Deficit Hyperactivity Disorder (ADHD). However, these children can have issues retaining attention to such an exercise. In this paper we present a study of ChillFish, a respiration game for children with ADHD. Our findings show tendencies that the game works in terms of having a calming effect. However, the study also highlighted issues of evaluating biofeedback games with children with ADHD that are not present when evaluating with adults. This work presents an iteration in the ChillFish development cycle that will hopefully result in a stable system that can assist children with ADHD in their everyday life.
O papel da Gestão de Pessoas no Turismo

A gestao dos colaboradores e do seu talento deve ser estrategica no sentido de adequar as pessoas as funcoes ou trabalhos de acordo com os objectivos estrategicos da empresa. A gestao das pessoas e das suas competencias no turismo e hotelaria deve ser no sentido de perceber como as competencias individuais podem ser mais efectivas para a forca de trabalho (Baum, 2008). O autor refere que o mercado de trabalho neste sector faz com que estas organizacoes tenham dificuldade em identificar talentos e muitas vezes tem de adoptar formas mais criativas para a sua identificacao e desenvolvimento. A formacao e desenvolvimento devem ser inclusivos para todos os colaboradores e nao selectivamente focados nos quadros superiores. Podemos constatar que os gestores no turismo e hotelaria devem ter uma abordagem da gestao de pessoas numa perspectiva sistemica dos processos de recrutamento, retencao e formacao dos colaboradores de forma a que a organizacao atraia, mantenha e desenvolva os talentos que sao necessarios a resultados efectivos da empresa. Comeca-se por fazer uma caracterizacao da gestao dos recursos humanos, fundamentando a importância do capital humano como valencia estrategica, em segundo lugar procede-se a uma pesquisa acerca das competencias valorizadas no âmbito do turismo e hotelaria. Por ultimo, sao enunciadas as praticas de gestao de pessoas nas empresas turisticas, nomeadamente, como se processa o recrutamento e seleccao de colaboradores, a retencao e a formacao e desenvolvimento.
An automatic method for the identification and interpretation of clustered microcalcifications in mammograms

We investigated a method for a fully automatic identification and interpretation process for clustered microcalcifications in mammograms. Mammographic films of 100 patients containing microcalcifications with known histology were digitized and preprocessed using standard techniques. Microcalcifications detected by an artificial neural network (ANN) were clustered and some cluster features served as the input of another ANN trained to differentiate between typical and atypical clusters, while others were fed into an ANN trained on typical clusters to evaluate these lesions. The measured sensitivity for the detection of grouped microcalcifications was 0.98. For the task of differentiation between typical and atypical clusters an Az value of 0.87 was computed, while for the diagnosis an Az value of 0.87 with a sensitivity of 0.97 and a specificity of 0.47 was obtained. The results show that a fully automatic computer system was developed for the identification and interpretation of clustered microcalcifications in mammograms with the ability to differentiate most benign lesions from malignant ones in an automatically selected subset of cases.
DRAM1 Protects Neuroblastoma Cells from Oxygen-Glucose Deprivation/Reperfusion-Induced Injury via Autophagy

DNA damage-regulated autophagy modulator protein 1 (DRAM1), a multi-pass membrane lysosomal protein, is reportedly a tumor protein p53 (TP53) target gene involved in autophagy. During cerebral ischemia/reperfusion (I/R) injury, DRAM1 protein expression is increased, and autophagy is activated. However, the functional significance of DRAM1 and the relationship between DRAM1 and autophagy in brain I/R remains uncertain. The aim of this study is to investigate whether DRAM1 mediates autophagy activation in cerebral I/R injury and to explore its possible effects and mechanisms. We adopt the oxygen-glucose deprivation and reperfusion (OGD/R) Neuro-2a cell model to mimic cerebral I/R conditions in vitro, and RNA interference is used to knock down DRAM1 expression in this model. Cell viability assay is performed using the LIVE/DEAD viability/cytotoxicity kit. Cell phenotypic changes are analyzed through Western blot assays. Autophagy flux is monitored through the tandem red fluorescent protein–Green fluorescent protein–microtubule associated protein 1 light chain 3 (RFP–GFP–LC3) construct. The expression levels of DRAM1 and microtubule associated protein 1 light chain 3II/I (LC3II/I) are strongly up-regulated in Neuro-2a cells after OGD/R treatment and peaked at the 12 h reperfusion time point. The autophagy-specific inhibitor 3-Methyladenine (3-MA) inhibits the expression of DRAM1 and LC3II/I and exacerbates OGD/R-induced cell injury. Furthermore, DRAM1 knockdown aggravates OGD/R-induced cell injury and significantly blocks autophagy through decreasing autophagosome-lysosome fusion. In conclusion, our data demonstrate that DRAM1 knockdown in Neuro-2a cells inhibits autophagy by blocking autophagosome-lysosome fusion and exacerbated OGD/R-induced cell injury. Thus, DRAM1 might constitute a new therapeutic target for I/R diseases.

Content based image retrieval system based on watershed transform for trademark images

The paper presents the development of content-based image retrieval system to search similar symbols from a collection of trademark images. The system consists of two stages i.e. feature extraction and similarity process. Watershed transform is employed to handle feature extraction process. Two features are derived from this stage i.e. object size and shape from each image. These features are used as the reference value for the next stage which consists of indexing and retrieval process. In this stage, a tree structure is built for handling index assignment that facilitates storing and searching process. Experiment has been conducted to measure system performance and the result shows that the developed CBIR system is useful to retrieve similar symbol from the collection of trademark images.
Psychological stress, appraisal, emotion and Cardiovascular response in a public speaking task

Forty-three undergraduates (30 males, 13 females) prepared and performed a speech task (stressor) or a reading task (no-stressor control). Preparing to speak led to greater threat appraisal, negative emotion, and cardiovascular (CV) response than preparing to read aloud, particularly in speech anxious individuals. Delivering the speech, however, did not result in an increment in CV response over and above preparation. Although threat appraisals could not explain the effect of stress on CV response during task preparation, negative emotion accounted for over half of the effect. These data support the hypothesis that CV response in these studies is at least partially accounted for by psychological processes (stressor-specific anxiety and negative emotional response) and suggests that these processes may be best studied during a period of stressor anticipation.
A NOVEL APPROACH TO GENERATE A SECURED CRYPTOGRAPHIC KEY FROM MULTIMODAL BIOMETRICS: FEATURE LEVEL FUSION OF FINGERPRINT AND IRIS

Human users have a tough time remembering long cryptographic keys. Therefore, researchers, for a long, period of time have been exploratory ways to utilize biometric features of the user instead of a memorable password or passphrase, in an effort to create strong and repeatable cryptographic keys. Our aim is to incorporate the volatility of the user’s biometric features into the generated key, so as to make the key unguessable to an attacker lacking significant knowledge of the user’s biometrics. We go one step further trying to incorporate multiple biometric modalities into cryptographic ke yg eneration so as to provide better security. In this article, we propose an efficient approach based on multimodal biometrics (Iris and fingerprint) for generation of secure cryptographic key. The proposed approach is composed of three modules namely, (i) Feature extraction, (ii) Multimodal biometric template generation and (iii) Cryptographic ke yg eneration. Initially, the features, minutiae points and texture properties are extracted from the fingerprint and iris images respectively. Subsequently, the extracted features are fused together at the feature level to construct the multi-biometric template. Finally, a 256-bit secure cryptographic key is generated from the multi-biometric template. For experimentation, we have employed the fingerprint images obtained from publicly available sources and the iris images from CASIA Iris Database. The experimental results illustrate the effectiveness of the proposed approach.
Pattern equivariant functions, deformations and equivalence of tiling spaces

Abstract We re-investigate the theory of deformations of tilings using P-equivariant cohomology. In particular, we relate the notion of asymptotically negligible shape functions introduced by Clark and Sadun to weakly P-equivariant forms. We then investigate more closely the relation between deformations of patterns and homeomorphism or topological conjugacy of pattern spaces.
On the girth of random Cayley graphs

We prove that random d‐regular Cayley graphs of the symmetric group asymptotically almost surely have girth at least (logd‐1|G|)1/2/2 and that random d‐regular Cayley graphs of simple algebraic groups over 𝔽q asymptotically almost surely have girth at least log d‐1|G|/dim(G). For the symmetric p‐groups the girth is between loglog |G| and (log |G|)α with α < 1. Several conjectures and open questions are presented. © 2009 Wiley Periodicals, Inc. Random Struct. Alg. , 2009
Variation for Epicuticular Waxes on Onion Foliage and Impacts on Numbers of Onion Thrips

Natural variation exists in onion (Allium cepa L.) for amounts of epicuticular waxes on foliage, and plants with lower amounts of these waxes suffer less feeding damage from onion thrips (Thrips tabaci Lind.). Wild-type onion possesses copious amounts of epicuticular waxes and is often referred to as ''waxy. '' The recessively inherited ''glossy'' phenotype has significantly less wax relative to waxy types and shows resistance to onion thrips but is vulnerable to spray damage, foliar pathogens, and excessive transpiration. Phenotypes visually intermediate between waxy and glossy also exist in onion, which we refer to as ''semiglossy. '' Epicuticular waxes on the leaves of glossy, semiglossy, and waxy onions were evaluated for appearance using scanning electron microscopy (SEM) and amounts and types were analyzed using gas chromatography/mass spectrometry. Wax crystals were clearly visible on the surface of waxy foliage with decreasing amounts on semiglossy and none on glossy leaves. The ketone hentriacontanone- 16 was the most prevalent wax on leaves of waxy onion and was significantly (P < 0.01) less on semiglossy relative to waxy plants and on glossy relative to waxy and semiglossy plants. Numbers of adult and immature onion thrips were significantly reduced (P < 0.05) on glossy and/or semiglossy accessions relative to waxy in field and greenhouse cage experiments. These results indicate that semiglossy plants possess intermediate amounts of epicuticular waxes that may protect leaves from diseases or environmental stresses while still conferring resistance to onion thrips. Therefore, the semiglossy phenotype should be useful in integrated programs managing this important onion pest.
Development of a guide robot interacting with the user using information projection — Basic system

This paper presents a guide robot with an information projection interface. The robot can detect multiple persons around it and choose the closest one as a user. This is realized using an omnidirectional camera and a laser range finder. The robot also has a projector with a pan-tile mechanism. It can project information anywhere in the environment and guide a person. The user can input commands by simple gestures using the foot on the dialog box projected onto the floor. After destination decision, the robot guides him/her by its motion and information projected onto the floor/wall/ceiling. The displayed information is changed corresponding to his/her position. Through experiments, we verified that the robot could detect a user and guide him/her.
The Role of Projection and Empathic Accuracy in Dyadic Perception between Older Twins

Dyadic perception between 108 older identical and same-sex fraternal twin pairs was examined using three different tasks: (i) an emotional sensitivity task, (ii) a Q-Sort rating of emotion-eliciting situations, and (iii) an assessment of each other's personality traits. Idiographic analyses related judgements of self and co-twin within and between twins. Projection approached the reliability of the judgements and was significantly higher than both empathic accuracy and actual similarity, suggesting that the process of dyadic perception was mainly shaped by projection. Significant correlations between empathic accuracy and projection were caused by the similarity of the twins in self-judgements. Empathic accuracy was much weaker once projection was controlled, indicating that twins had used valid projection to improve accuracy. Similarity-controlled projection was still high and reflected the fact that the twins overestimated their similarity to a large extent. Contrary to expectation but consistent across the three tasks, identical and fraternal twins differed neither in levels of actual similarity, empathic accuracy and projection, nor in similarity-controlled empathic accuracy and projection.
Ultralow specific on-resistance trench lateral power MOSFETs

Optimizing the trade-off relationship between the off-state breakdown voltage (BV) and specific on-resistance (Ron,sp) is the main concern for power MOSFETs. For lateral power MOSFETs, the trench technology exhibits significant improvements in the BV and Ron,sp by reducing the device pitch and increasing the channel density, and thus improves the tradeoff between BV and Ron,sp. This paper presents novel trench-type lateral power MOSFETs and their operation mechanisms proposed by Power Integrated Technology Lab.

A Multi-Resolution Approach to Characterize the Connectivity Structure and Evolution of Large Graphs

Graphs are widely used to represent the structure of large networked systems such as Online Social Networks (OSN). These graphs have a large number of evolving nodes (i.e., users) and edges (i.e., relationships). It is important to have practical methods to capture and characterize the connectivity structure and evolution patterns of such networks to gain insights about the corresponding system. However, existing techniques for graph analysis have limited scalability, offer limited insight about graph structure, and often do not capture the graph evolution. In this study, we present a new multiresolution method to characterize the connectivity features and evolution of large graphs. The main idea is to divide the graph into a manageable number of meaningful elements and characterize inter and intra-element connectivity. We focus on the subgraphs of high degree nodes, i.e., core nodes, and identify the community of core nodes, i.e., core communities, as the main elements of the graph. This method allows us to perform the following analysis: 1) spatial analysis to determine how the size of core subgraph affects the number and characteristics of core communities which control the resolution of our analysis, 2) temporal analysis to characterize the evolution patterns of the core communities over time, and 3) spatiotemporal analysis to relate the spatial and temporal analysis. We use 14 snapshots of Google+ OSN to illustrate the capabilities of our approach.
A Metabolically Healthy Obese Phenotype in Hispanic Participants in the IRAS Family Study

Objective: Some obese individuals appear to be protected from developing type 2 diabetes mellitus and cardiovascular disease (CVD). This has led to characterizing body size phenotypes based on cardiometabolic risk factors specifically as obese or overweight, and as metabolically healthy (MH) or metabolically abnormal (MA) based upon blood pressure, lipids, glucose homeostasis, and inflammatory parameters. The aim of this study was to measure the prevalence of and describe fat distribution across these phenotypes in a minority population.
The Application of XML and Web service on Database Security Control Mode in Pervasive Space

When database resources being integrated into the pervasive environment, the universal key problem to solve is access mechanisms of database security. The database security mechanisms have already been firmed in the database system. When more flexible security schemas to adapt to the pervasive environment are needed, the database system could solve the problem above insufficiently by itself. We could make full uses of the advantages of XML and Web service to deal with the problem above. This paper proposes such flexible a database security model using XML as the middleware and Web service as the communication tool in different platforms in pervasive environment that the problems of database security could be solved wonderfully in pervasive environment.
An integrated 10/5GHz injection&#8211;locked quadrature LC VCO in a 0.18&#181;m digital CMOS process

We present a 5GHz quadrature LC voltage controlled oscillator based on super-harmonic injection locking to an on-chip free-running 10GHz master oscillator. The oscillators are fabricated in a 0. 18µm, low voltage digital CMOS process with a lossy substrate (ρ ∼20mohm-cm) and thin (1.6/µm), high resistivity M6. All the oscillators use fully integrated, low Q (∼4) spiral inductors. The 10GHz master oscillator achieves a tuning range of 1.4GHz, and a phase noise of -118dBc/Hz at a 1MHz offset. We measured the phase noise of the quadrature VCO to be 6dBc/Hz lower than that of the free-running master oscillator. The oscillator core draws 14mA from a 1.6V supply. An image reject receiver built using the quadrature signals provides nearly 40dB of image rejection, confirming better than 1° of quadrature matching. An on-chip frequency locked loop is shown to guarantee capture and accurate quadrature generation in the presence of an additional artificially introduced, 10% mismatch in the natural frequencies.
Study of the Behavior of a Bell-Shaped Colonic Self-Expandable NiTi Stent under Peristaltic Movements

Managing bowel obstruction produced by colon cancer requires an emergency intervention to patients usually in poor conditions, and it requires creating an intestinal stoma in most cases. Regardless of that the tumor may be resectable, a two-stage surgery is mandatory. To avoid these disadvantages, endoscopic placement of self-expanding stents has been introduced more than 10 years ago, as an alternative to relieve colonic obstruction. It can be used as a bridge to elective single-stage surgery avoiding a stoma or as a definitive palliative solution in patients with irresectable tumor or poor estimated survival. Stents must be capable of exerting an adequate radial pressure on the stenosed wall, keeping in mind that stent must not move or be crushed, guaranteeing an adequate lumen when affected by peristaltic waves. A finite element simulation of bell-shaped nitinol stent functionality has been done. Catheter introduction, releasing at position, and the effect of peristaltic wave were simulated. To check the reliability of the simulation, a clinical experimentation with porcine specimens was carried out. The stent presented a good deployment and flexibility. Stent behavior was excellent, expanding from the very narrow lumen corresponding to the maximum peristaltic pressure to the complete recovery of operative lumen when the pressure disappears.
