Stress Level, Health Behaviors, and Quality of Life in Employees Joining a Wellness Center

Purpose. Examine the relationship between stress level and quality of life at a worksite wellness center. Design. A survey completed when joining the wellness center. Setting. Employee wellness center. Subjects. Survey that inquired about stress, health behaviors, and quality of life of more than 13,000 employees joining a wellness center. Measures. A series of questions about current health status and health behaviors. Analysis. Two-sample t-tests assuming unequal variances. Results. A total of 2147 of these employees reported having high stress levels. Employees with high stress levels had statistically significant lower quality of life, more fatigue, and poorer health compared with employees with low stress levels. In terms of their ability and motivation to participate in wellness programs, the high-stress employees were also less active and had less healthy nutritional habits, less support, and less confidence in their ability to be active. They also reported having more health problems, including high blood pressure, high blood sugar, high cholesterol, and overweight. Conclusions. It appears that employees with high stress levels—those who might most benefit from participation in wellness programs—may experience the greatest difficulty participating actively in wellness programs because of their lack of support, low confidence, and numerous health problems. Perhaps offering tailored stress reduction programs for these employees would be beneficial.
A Framework for Leveraging Cloud Computing to Facilitate Biometrics at Large-Scale

The cloud computing paradigm provides an efficient environment for the large-scale use of biometric identification systems. However, there is no established standard for the configuration of the cloud or the type of components necessary to achieve optimal biometric performance. In this paper, we present a conceptual framework which addresses the challenges and the requirements of the biometrics at large-scale while dramatically increasing the performance. In this paper, our contributions are three-fold. First, we describe the related work pertaining to biometric integration with cloud computing. Second, we discuss the issues and challenges preventing biometrics from being adopted at large-scale which influenced the design choices of our proposed framework. Finally, we present the proposed framework and highlight the cloud services that should be utilized with the proper configurations to maximize the biometric efficiency. We also discuss the realization of our proposed framework and the components selected. To show the practicality of the framework, we chose Amazon Web Services even though our framework is applicable to any cloud platform that supports the design criteria. Keywords—biometrics; cloud computing; large-scale implementation; authnetication; MapReduce; Hadoop
First experience in analysing pulsatile retinal capillary flow and arteriolar structural parameters measured noninvasively in hypertensive patients

Objective: Increased pulsatile pressure induces as well as aggravates microvascular damage. Scanning laser Doppler flowmetry allows the noninvasive assessment of both retinal capillary flow (RCF) and arteriolar structural parameters of the retinal circulation. Moreover, pulsatile characteristics of the retinal arterioles can be assessed. Methods: In study 1, reliability of pulsatile RCF and structural parameters were examined in randomly selected patients. In study 2, pulsatile RCF as well as the structural parameters of retinal arterioles were assessed in hypertension grade 1–2 (HT1–2; n = 20) and treatment-resistant hypertension (TRH; n = 19). Results: In study 1, test–retest, interobserver and intraobserver reliability of all parameters showed coefficients of variation of less than 10%. In study 2, it was shown that patients with TRH had higher pulse pressure (P = 0.003) and pulsed RCF values (P < 0.001) as patients with HT1–2. Patients with HT1–2 had no change in the vessel diameter, but a significant difference in lumen diameter, resulting in an altered wall thickness (P = 0.001) between systole and diastole. In contrast, patients with TRH showed differences in vessel diameter (P = 0.005) as well as lumen diameter (P = 0.001), resulting in an unaltered wall thickness between systole and diastole. Hence, wall thickness change as a result of pulsed flow regulation observed in HT1–2 was missing in TRH. Conclusion: We suggest a new reliable tool for evaluating the pulsatility in the retinal circulation in humans, and found significant differences in pulsatile RCF and structural parameters between patients with HT1–2 and those with TRH.
Coronary Sinus Cryoablation of Ventricular Tachycardia after Failed Radiofrequency Ablation

We present a case of Great Cardiac Vein (GCV) cryoablation in order to suppress idiopathic epicardial Ventricular Tachycardia (VT) after failed Radiofrequency (RF) ablation via the epicardium and GCV. RF ablation is the technique of choice for the treatment of Ventricular Arrhythmias (VA). However, this procedure has its limitations when delivered inside the distal cardiac veins. Cryoablation is a good alternative in patients where RF cannot be used because of risk of high impedance.
Temperature dependence in modeling photovoltaic arrays

Photovoltaic (PV) array output varies with environmental conditions. In this paper, an improved algorithm is proposed to model PV arrays at temperatures different than the nominal temperature. The proposed model is validated with experimental data of Kyocera KC200GT multi-crystalline silicon solar array. The superiority of this technique is proved by computing modeling absolute error to have a maximum error as 0.98% of array short circuit current. In addition, the high accuracy of the proposed technique is proved in modeling a commercial mono-crystalline silicon solar array (Shell SP70). A graphical user interface (GUI) is also developed based on the improved approach to model PV arrays at different temperatures.
Graphene-Based Wireless Environmental Gas Sensor on PET Substrate

Modern gas detection systems have expanded into the monitoring of greenhouse gases, which are believed to cause global warming and are toxic to the human body. This demand has led to the development of numerous different discrete and distinct sensor technologies. A wireless sensing system is formed using the integrated arrays of field-effect transistors and sensors comprising graphene channels, silver nanowire electrodes, and interconnects with a wireless communication antenna. These carbon devices are highly flexible and can be transferred onto both planar and non-planar substrates, including papers, clothes, fingernails, and human skin. The printed wireless sensing antenna senses the gases by detecting the change in the signal produced by a change in sensor resistance.

Oníya Ošóka: The Interpretation of Oglála Lakȟóta Continuing and Historical Relational Connections at Wind Cave National Park

Author(s): Bear Eagle, Sina Rose | Advisor(s): McCarty, Teresa L; Kroskrity, Paul V | Abstract: Within the National Park Service, interpretation is utilized to create emotional connections between the visitor and the site, to convey to the public the value of National Park resources, and to impart a need for their protection. This research project seeks to explore this topic by analyzing the ways in which Oglala Lakȟota continuing and historical relational connections are represented through interpretation at Wind Cave National Park, a site chosen for its status as a site of relational significance and associations with Lakȟota oral history, its location within the contested Black Hills area of South Dakota, and its proximity to the Pine Ridge Indian Reservation. Employees from Wind Cave National Park and the Oglala Sioux Tribe were interviewed for this study, which combines both storytelling and analytical emphases.
Moderators of response to telephone continuing care for alcoholism.

OBJECTIVES To evaluate potential moderators of the effect of adding extended telephone monitoring (TM) and telephone monitoring and counseling (TMC) continuing care to treatment as usual (TAU) for alcoholism. Continuing care was predicted to be more effective for patients with severe substance-use histories, poor initial response to treatment, and other risk factors for relapse. METHODS Randomized study with 18-month follow-up. Outcomes were frequency of drinking and any drinking. RESULTS Main effects favored TMC over TAU on alcohol outcomes. However, none of the 11 variables examined moderated these effects. Conversely, main effect and moderator analyses indicated TM was more beneficial than TAU only for women and for participants with lower readiness to change. CONCLUSIONS TMC improves drinking outcomes when added to standard care, regardless of alcohol use history, early response to treatment, or other risk factors for relapse. TM is recommended for women and less motivated patients.
Mechanochemical defect engineering of HKUST-1 and impact of the resulting defects on carbon dioxide sorption and catalytic cyclopropanation

Metal–organic frameworks (MOFs) are recognized as ideal candidates for many applications such as gas sorption and catalysis. For a long time the properties of these materials were thought to essentially arise from their well-defined crystal structures. It is only recently that the importance of structural defects for the properties of MOFs has been evidenced. In this work, salt-assisted and liquid-assisted grinding were used to introduce defects in a copper-based MOF, namely HKUST-1. Different milling times and post-synthetic treatments with alcohols allow introduction of defects in the form of free carboxylic acid groups or reduced copper(i) sites. The nature and the amount of defects were evaluated by spectroscopic methods (FTIR, XPS) as well as TGA and NH3 temperature-programmed desorption experiments. The negative impact of free –COOH groups on the catalytic cyclopropanation reaction of ethyl diazoacetate with styrene, as well as on the gravimetric CO2 sorption capacities of the materials, was demonstrated. The improvement of the catalytic activity of carboxylic acid containing materials by the presence of CuI sites was also evidenced.
Cross‐talk of parathyroid hormone‐responsive dual signal transduction systems in osteoblastic osteosarcoma cells: Its role in PTH‐induced homologous desensitization of intracellular calcium response

The present study was designed to characterize the cross‐talk of parathyroid hormone (PTH)‐responsive dual signal transduction systems (cAMP‐dependent protein kinase (PKA) and calcium/protein kinase C [PKC]) and its participation in PTH‐induced homologous desensitization of intracellular calcium ([Ca2+]i) in osteoblastic UMR‐106 cells. Although our recent study revealed that prolonged (more than 2 h) pretreatment with PKC‐activating phorbol ester, phorbol 12‐myristate 13‐acetate (PMA) significantly decreased the PTH‐stimulated cAMP production, pretreatment with PMA (10−7 and 10−6 M) but not 10−6 M 4alphaphorbol 12,13‐didecanoate (PDD), incapable of activating PKC for 30 min significantly augmented 10−7 M hPTH‐(1‐34)‐stimulated cAMP production. H‐7 (50 uM), a PKC inhibitor, significantly antagonized this PMA‐induced effect. Pretreatment with 10−6 M PMA for 30 min did not affect PTH receptor binding but significantly augmented a cAMP responsiveness to 10−5 M forskolin and 1 ug/ml cholera toxin. Pertussis toxin (0.5 ug/ml) did not affect the PMA‐induced augmentation of the PTH‐stimulated cAMP production. PTH caused a complete homologous desensitization of [Ca2+]i response within 30 min. Pretreatment with 10−4 M dibutyryl cAMP for 30 min and 6 h significantly reduced and completely blocked the PTH‐induced increase in [Ca2+]i, respectively. Pretreatment with 10−4 M Sp‐cAMPS, a direct PKA activator, for 30 min completely blocked the PTH‐induced increase in [Ca2+]i. Rp‐cAMPS (10−4 M), an antagonist of PKA, slightly but significantly antagonized the PTH‐induced homologous desensitization of [Ca2+]i response. The present study indicates that the time of exposure to PKC activation is a critical determinant in modulating the cAMP system, while PKA activation counterregulatorily acts on the [Ca2+]i system, and that PKA activation is linked to the PTH‐induced homologous desensitization of [Ca2+]i response. © 1994 Wiley‐Liss, Inc.
Tracking of the motion path of a person from video streams for the overlapping case

The tracking and recognition of human motion, action, and events using computer vision has recently gained widespread interest in both academic research and industrial, with much emphasis on real-time systems. This paper presents a fast and accurate method for tracking the motion path of a person from the video stream. The motion data of the people are acquired in possible cases such as occlusion or overlapping with each other. This system provides to extract the motion of each player individually from successive image frames. Especially, the trajectories for each player are obtained in the whole video sequence of sport game and in every instance of time for using the sport training system. Singular value decomposition of Gaussian elimination method is applied to determine the matched person from previous image. The motion trajectory of a player is considered not only for normal case but also for overlapping case. Through the experimental results, the proposed system works adequately.
Code rate adaptation for mitigating the effects of Detect And Avoid (DAA) mechanism on the performance of UWB systems

Ultra wideband (UWB) systems can cause potential interference to other narrowband systems sharing the same band, such as WiMax and Wi-Fi. Detect and avoid (DAA) mechanisms were suggested as a cognitive radio-based solution to reduce interference by adaptively reducing the transmitted power at the overlapping bands. Applying this mechanism may result in degrading the performance of UWB transmissions. In this paper, we suggest a minor modification to the DAA mechanism to mitigate this effect while preserving data rate, and thus providing UWB with more reliability. Simulation results show significant improvement in performance over various interference scenarios and data rates.
Learning to Learn: Real-Time Features and a Connectionist Model

Two experiments used classical conditioning to examine transfer of response features specific to the warning interval between a conditioned stimulus (CS) and an unconditioned stimulus (US). Rabbits were given initial training with a stimulus (CSA) in one modality (tone) at a designated interval (e.g., 200 ms). In a second stage, the conditioned response (CR) to CSA was extinguished. Finally, training was shifted to a new stimulus (CSB) in another modality (light) at a new interval (e.g., 400 ms). Compared to rest controls, there was an enhanced rate of CR acquisition to CSB and a tendency for early CRs to CSB to reflect the CSA-US interval. However, the extinction procedure and the change in CS-US interval together reduced these two aspects of transfer across stimulus modalities. The findings are discussed in terms of their implications for theories of cross-modal transfer. A layered network with real-time features is offered.
THE IMPORTANCE OF ANTIOXIDANT AND THEIR ROLE IN PHA RMACEUTICAL SCIENCE-A REVIEW

INTRODUCTION Antioxidants are an inhibitor of the process of oxidation, even at relatively small concentration a nd thus have diverse physiological role in the body. Antioxidant constituents of the plant material act s radical scavengers, and helps in converting the radicals to less reactive species. A variety of fre e radical scavenging antioxidants is found in dietary sources like fruits, vegetables and tea, etc. This ABSTRACT The addition of synthetic antioxidants to oils and/or foods is one of the most efficient ways to prevent lipid oxidation. However, the safety of synthetic additives has been questione d stimulating the evaluation of naturally occurring compo unds with antioxidative properties. Although there is no a ssurance of the safety of natural antioxidants, there is some comfort knowing that such antioxidants are purified from natur l products that have been consumed for generations. Phenoli c compounds in plants are recognized as important compounds in conferring stability against oxidation. Natural ant ioxidant phenolics can be classified into a lipophilic group, toco pherols, and a hydrophilic group, including simple p henolics, phenolic acids, anthocyanins, flavonoids and tannins. Even t hough chemists have elucidated the structures of thousands of phenolics, there are still many compounds that have not y et been fully characterized and they are referred as phenolic extracts. In this ways berry extracts, aromatic plant ex tracts, essential oils and their components are gaining int erest because of their relatively safe and wide acceptance by consumers. Many authors have reported antioxidant and radical-scavenging properties by berries, spices and essential oils. In this w ork e reviewed the most important groups of natural an tioxidants, with some peculiarities related to chemical composition. O xidative stress can be caused in result of free radicals fo rmation. Aging and different chronic diseases including diabetes, can cer and cardiovascular diseases could be caused by oxidative stress. Antioxidants are important factor to maintain o ptimal cellular and human body health. Medicinal plants are an important source of antioxidants16. Natural antioxidants increase the antioxidant capacity of the plasma and reduce t he risk of certain diseases. four synthetic antioxidants are widel y used in foods; namely, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), propyl gallate (PG), and tert-b u ylhydroquinone (TBHQ).
Screening guidelines for colorectal cancer and polyps in patients with acromegaly

Acromegaly is characterised by excessive levels of circulating growth hormone and its tissue mediator, IGF-1. Before effective treatment and lowering of growth hormone and IGF-1 the majority of patients with the disease died by the aged of 60 years.1,2 This was largely attributable to diabetes mellitus and cardiovascular and cerebrovascular diseases. More recently, it has become apparent that patients with acromegaly have an increased prevalence of colorectal adenomas and cancer.3–20 It is probable that with more effective and aggressive treatment of both the underlying acromegaly and its metabolic and vascular complications, patients are now surviving long enough to develop malignant complications of the disease. That this increased risk might be related to serum growth hormone and/or IGF-1 levels is supported by recent epidemiological studies in the non-acromegalic population that have demonstrated an association between serum IGF-1 and the risk of colorectal cancer.21,22 1. Patients with acromegaly should be offered regular colonoscopic screening, starting at the age of 40 years. (Recommendation Grade: B ) 2. The frequency of repeat colonoscopy should depend on the findings at the original screening and the activity of the underlying acromegaly. (Recommendation Grade: B) 3. Patients with an adenoma at first screening or increased serum IGF-1 level above the maximum of the age corrected …

Neural invasion in pancreatic carcinoma.

BACKGROUND Neural invasion is a special metastatic route in pancreatic cancer and responsible for the high recurrence in curatively resected cases. OBJECTIVE To summarize the characteristics and mechanisms of neural invasion in pancreatic carcinoma for the better treatment of this disease. DATA SOURCES The international literatures were reviewed about the definition, incidence and mechanisms of neural invasion and its clinicopathology, diagnosis and treatment. DATA SYNTHESIS Neural invasion is defined when the medial perineurium is involved by cancer cells, accounting for 45%-100% of all cases. It can be divided into different kinds or stages according to its locations and the number of nerve fascicles involved. Invasion along vascularity, lymphatic vessels, perineural space and neurotropism is considered as its primary mechanisms. No clinicopathologic factors are correlated with neural invasion. Intravascular ultrasound, CT scan and immunostaining K-ras gene analysis can be used to diagnose neural invasion pre-, intra- or postoperatively. CONCLUSION Neural invasion is an important prognostic factor for the recurrence of pancreatic carcinoma after pancreatectomy. Because of its high incidence, pancreatectomy with extended radical retroperitoneal dissection should be considered as a basic procedure in the treatment of pancreatic carcinoma.
