BLOOD LEVELS OF LONG-CHAIN n – 3 FATTY ACIDS AND THE RISK OF SUDDEN DEATH C

A BSTRACT Background Experimental data suggest that longchain n¡3 polyunsaturated fatty acids found in fish have antiarrhythmic properties, and a randomized trial suggested that dietary supplements of n¡3 fatty acids may reduce the risk of sudden death among survivors of myocardial infarction. Whether long-chain n¡3 fatty acids are also associated with the risk of sudden death in those without a history of cardiovascular disease is unknown. Methods We conducted a prospective, nested case– control analysis among apparently healthy men who were followed for up to 17 years in the Physicians’ Health Study. The fatty-acid composition of previously collected blood was analyzed by gas–liquid chromatography for 94 men in whom sudden death occurred as the first manifestation of cardiovascular disease and for 184 controls matched with them for age and smoking status. Results Base-line blood levels of long-chain n¡3 fatty acids were inversely related to the risk of sudden death both before adjustment for potential confounders (P for trend=0.004) and after such adjustment (P for trend=0.007). As compared with men whose blood levels of long-chain n¡3 fatty acids were in the lowest quartile, the relative risk of sudden death was significantly lower among men with levels in the third quartile (adjusted relative risk, 0.28; 95 percent confidence interval, 0.09 to 0.87) and the fourth quartile (adjusted relative risk, 0.19; 95 percent confidence interval, 0.05 to 0.71). Conclusions The n¡3 fatty acids found in fish are strongly associated with a reduced risk of sudden death among men without evidence of prior cardiovascular disease. (N Engl J Med 2002;346:1113-8.)
Pediatric Clinical Practice Guidelines for Acute Procedural Pain: A Systematic Review

BACKGROUND: Procedural pain assessment and management have been extensively studied through multiple research studies over the past decade. Results of this research have been included in numerous pediatric pain practice guidelines. OBJECTIVE: To systematically review the quality of existing practice guidelines for acute procedural pain in children and provide recommendations for their use. METHODS: A systematic search was conducted on Medline, Embase, CINAHL, PsycINFO, and Scopus from 2000 to July 2013. A gray literature search was also conducted through the Translating Research Into Practice database, Guidelines International Network database, and National Guideline Clearinghouse. Four reviewers rated relevant guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE) II Instrument. Screening of guidelines, assessment of methodological quality, and data abstraction were conducted by 2 pairs of raters. Disagreements in overall assessments were resolved through consensus. RESULTS: Eighteen guidelines from 4930 retrieved abstracts were included in this study. Based on the AGREE II domains, the guidelines generally scored high in the scope and purpose and clarity of presentation areas. Information on the rigor of guideline development, applicability, and editorial independence were specified infrequently. Four of the 18 guidelines provided tools to help clinicians apply the recommendations in practice settings; 5 were recommended for use in clinical settings, and the remaining 13 were recommended for use with modification. CONCLUSIONS: Despite the increasing availability of clinical practice guidelines for procedural pain in children, the majority are of average quality. More transparency and comprehensive reporting are needed for the guideline development process.
Impaired Hearing in Mice Lacking Aquaporin-4 Water Channels*

A role for aquaporins (AQPs) in hearing has been suggested from the specific expression of aquaporins in inner ear and the need for precise volume regulation in epithelial cells involved in acoustic signal transduction. Using mice deficient in selected aquaporins as controls, we localized AQP1 in fibrocytes in the spiral ligament and AQP4 in supporting epithelial cells (Hensen's, Claudius, and inner sulcus cells) in the organ of Corti. To determine whether aquaporins play a role in hearing, auditory brain stem response (ABR) thresholds were compared in wild-type mice and transgenic null mice lacking (individually) AQP1, AQP3, AQP4, and AQP5. In 4–5-week-old mice in a CD1 genetic background, ABR thresholds in response to a click stimulus were remarkably increased by >12 db in AQP4 null mice compared with wild-type mice (p < 0.001), whereas ABR thresholds were not affected by AQP1, AQP3, or AQP5 deletion. In a C57/bl6 background, nearly all AQP4 null mice were deaf, whereas ABRs could be elicited in wild-type controls. ABRs in AQP4 null CD1 mice measured in response to tone bursts (4–20 kHz) indicated a frequency-independent hearing deficit. Light microscopy showed no differences in cochlear morphology of wild-type versus AQP4 null mice. These results provide the first direct evidence that an aquaporin water channel plays a role in hearing. AQP4 may facilitate rapid osmotic equilibration in epithelial cells in the organ of Corti, which are subject to large K+ fluxes during mechano-electric signal transduction.
Blockchain Economics

When is record-keeping better arranged through a blockchain than through a traditional centralized intermediary? The ideal qualities of any record-keeping system are (i) correctness, (ii) decentralization, and (iii) cost efficiency. We point out a blockchain trilemma: no ledger can satisfy all three properties simultaneously. A centralized record-keeper extracts rents due to its monopoly on the ledger. Its franchise value dynamically incentivizes correct reporting. Blockchains drive down rents by allowing for free entry of record-keepers and portability of information to competing “forks. ” Blockchains must, therefore, provide static incentives for correctness through computationally expensive proof-of-work algorithms and permit record-keepers to roll back history in order to undo fraudulent reports. While blockchains can keep track of ownership transfers, enforcement of possession rights is often better complemented by centralized record-keeping.
4 Design of CMOS for 60 GHz Applications

Recently, 7GHz of unlicensed bandwidth around 60GHz was opened allowing for a variety of applications including Gb/s point-to-point links, wireless local area networks with extraordinary capacity, and vehicular radar at nearby frequencies. Presently, the exploitation of this band is minimal because of the high cost of the compound semiconductor technology needed to process the mm-wave signals. However, as the high-frequency capabilities of CMOS improve through scaling, the question is not if, but when will CMOS become a viable alternative for mm-wave applications.
6B.5 LATENT HEATING RETRIEVAL FROMM TRMM OBSERVATIONS USING A SIMPLIFIED THERMODYNAMIC MODEL

Knowledge regarding the spatial and temporal distribution of heating in the Tropics is required for various applications. These applications range from long-term climate prediction to storm-scale diagnostics and forecasting. A comprehensive discussion may be found in Olson et al. (1999). The large spectrum of applications justified the development of algorithms for latent heating estimation from observations provided by space borne instruments. Examples of such algorithms are those derived by Olson et al. (1999) for passive microwave observations, Tao et al. (1993), and Yang and Smith (1999) for both passive and active microwave observations. Olson et al. (1999) algorithm is based on a Bayesian procedure that assigns, for a given set of observations, probabilities to a set of latent heating profiles derived from cloud model simulations. Tao et al. (1993) use only the surface precipitation, a convective-stratiform classification, and a set of normalized latent-heating profiles (derived also from cloud model simulations), while Yang and Smith (1993) assume a steady-state and use hydrometeor conservation equations to estimate the latent heating. Given the lack of information regarding the dynamics of the observed precipitation, only approximate algorithms may be derived, and, as apparent from the above description, various approaches are possible. In this study, we investigate a hybrid, computationally more demanding,approach that may yield results superior to those from the existing algorithms. The approach is based on a system of simplified hydroand thermodynamic equations that are integrated in time until a steady state is achieved. A statistical procedure is used for the system initialization. Thus, the formulation extends two of the existing algorithms. The approach, which is devised to use observations from the precipitation radar (PR) onboard the Tropical Rainfall Measuring Mission (TRMM), is evaluated using synthetic data derived from cloud model simulations.
Effect of Cumulus Cells on the Efficiency of Vitrified-Thawed Immature Cattle Oocytes

The present work was designed to examine the effect of the presence or absence of cumulus cells on the efficiency of vitrification of immature cattle oocytes. In our experiment, we had two groups: group 1, immature cattle oocytes with cumulus cells and group 2, immature cattle oocytes without cumulus cells. The two groups underwent vitrification using 20% ethylene glycol and 20% DMSO, and then thawed, and in vitro matured in TCM-199 medium and examined after 22 hours for assessment of nuclear maturation. Higher survival rate (p < 0.05) after thawing was observed in group 1 (84.6%) than group 2 (57.8%). After in-vitro maturation, the rate of MII oocytes was significantly higher (p < 0.05) in group 1 (74.4%) than group 2 (47.7%). In conclusion, the cumulus cells are very important in increasing the survivability and developmental rate of vitrified-thawed immature cattle oocytes.
Simple 3-D Mouse with Auto-error-correction Function

3-D mice are used for drawing 3-D computer graphics in the field of Virtual Reality. They are far more expensive and complicated than usual 2-D mice. This paper proposes a low-cost, simple 3-D mouse. It uses a part of the 2-D mouse's mechanism for low-cost. Its software automatically corrects the coordinate errors caused by hardware. Its performance is shown through experiments, comparing with other 3-D mice.
Derksen Direct simulations of aggregates in homogeneous isotropic turbulence

We study aggregation in turbulent flow by means of particle-resolved, direct numerical simulations. Mono-sized spheres with an attractive square-well potential are released in homogeneous, isotropic turbulence generated through linear forcing. Typical cases have a solids volume fraction of 0.08 and a ratio of the Kolmogorov scale over the primary sphere radius of O(0.1). The latter implies that the flow around the primary spheres is inhomogeneous. The simulations show the continuous formation and breakage of aggregates as a result of the turbulence and the attractive potential. The average size of the aggregates is a pronounced function of the strengths of turbulence and interaction potential. Fractal dimensions of the aggregates are in the range 1.4–1.8 for the cases studied.
Outdoor evaluation of luminescent solar concentrator prototypes.

In this paper we present an outdoor evaluation of luminescent solar concentrators (LSC) throughout the whole day with different weather conditions. An electric gain of Gp= 25% was obtained with a LSC of PMMA doped with KF-241 dye. These results are compared with those previously reported.
Analysis of H-2 determinants recognized during the induction of H-Y-immune cytotoxic T cells by monoclonal antibodies in vitro

Monoclonal antibodies directed to the D region of H-2(k) when present during in vitro culture inhibit the generation of CBA/H and C3H.H-2(o) H-Y-immune cytotoxic T cells . Monoclonal antibodies directed to the I-A(k) and I-E(k) region specifically inhibited induction of CBA/H H-Y-immune cytotoxic T cells only when they were present simultaneously in culture. These findings show T helper cell requirement for CBA/H H-Y-immune cytotoxic T cell induction, and suggest that two I region-coded restriction antigens for T helper cells are involved.
What should we tell prostate cancer patients about (secondary) prevention?

Purpose of review To briefly summarize the epidemiologic findings of selected lifestyle factors for prostate cancer progression, metastasis, or death, with a focus on behaviors after diagnosis where possible. We conclude by providing guidance on the lifestyle practices that physicians may wish to prioritize for discussion with their patients. Recent findings Growing, but still limited, evidence suggests that lifestyle factors after prostate cancer diagnosis may impact prostate-cancer-specific and overall morality. In particular, smoking and obesity may increase the risk of disease progression and mortality, whereas engaging in vigorous physical activity or brisk walking and consuming a diet rich in vegetables (particularly tomato sauce and cruciferous) and vegetable fats may lower the risk. Summary Patients should be counseled not to use tobacco products; to engage in daily physical activity; to minimize sedentary behavior; to consume plenty of healthy fats (i.e. fish, nuts, vegetable oils, soybeans, avocados, and flaxseed) and vegetables; to focus on getting nutrients from foods rather than supplements; and to limit refined grains, sugars, processed meat, and high-fat dairy.
Improvement process of partially cooked corn grit (PCCG) preparation

Steamed corn grits, or nasi jagung, is an indigenous, corn-based product, which is usually used to substitute rice, particularly in the central part of Java and Madura regions, Indonesia. However, there is limited information regarding the preparation of partially cooked corn grits (PCCG). The objective of the present work was therefore to compare the preparation of PCCG in terms of characteristics and time of preparation using optimised initial moisture content in the traditional process with optimised corn particle size, initial moisture content and processing temperature of the improved process. Water absorption index (WAI), water solubility index (WSI), yellowness index (YI), and resistant starch (RS) of dried PCCG, as well as textural properties of rehydrated PCCG, were compared between optimised PCCG prepared using traditional and improved processes to obtain the best PCCG. Results showed that the optimum initial moisture content to prepare PCCG by the traditional process was approximately 40%. The optimum conditions to prepare PCCG by the improved process were 300 μm corn particle size, 52.33% initial moisture content and 123.67°C processing temperature. PCCG prepared using the improved process had higher values of YI (99.51) and RS (3.65 g/100 g) but lower WAI value (3.74) than YI (95.78), RS (1.96 g/100 g) and WAI (3.96) of PCCG prepared using the traditional process. The textural properties of rehydrated PCCG, except for adhesiveness and cohesiveness, prepared using the improved process were not different from those of PCCG prepared using the traditional process. The improved process also had a shorter preparation time of PCCG, which was 4-6 h as compared to normally 3-4 d in the traditional process. Therefore, a more rapid process with more consistent qualities for preparing PCCG will be of benefit to the target population.
Synthesis , Characterization and CO-Releasing Properties of Linked Alkyne-Bridging Cobalt Carbonyl Clusters

A new group of CO-releasing molecules (CORMs), linked alkyne-bridging tetrahedral carbonyl clusters, [CO2(CH2C≡CH-μ)2][Co2(CO)6]2 (I), [(CH2)8(CO2CH2C≡CH-μ)2][Co2(CO)6]2 (II) and [(CH2)8 (CO2-CH2C≡CH-μ)2][Co4(CO)8](PPh3)4] (III) have been prepared by reaction of Co2(CO)8 with two dipropargyl esters (HC≡CCH2OOC)2, (CH2)8(CO2CH2C≡CH)2 and PPh3, respectively. All clusters were characterized by elemental analysis, HNMR and IR spectroscopy. Cluster III was also characterized by CNMR, PNMR and MS spectroscopy. The properties of CO releasing from the three clusters was investigated spectro-photometrically by measuring the conversion of deoxymyoglobin (deoxy-Mb) to carbonmonoxy myoglobin (MbCO) in phosphate buffered saline (PBS) solution (PH=7.4) at 37°C. The cluster II shows the best con-trollable CO-Releasing result among these clusters.
Effects of fentanyl and butorphanol on uterine contraction pain after induced abortion : a randomized controlled clinical trial

Objective: Surgical induced abortion is a common remedy for contraceptive failure, usually processed under intravenous anesthesia in a clinic. Uterine contraction pain often occurs after the operation, affecting recovery or inducing more severe complications in women. Methods: To relieve this kind of pain, this study performed a randomized controlled trial using common analgesics, including fentanyl and butorphanol, from January to December in 2016. Ninety-nine patients meeting the inclusion criteria were included in the study and randomly divided into three groups: propofol group, fentanyl group, and butorphanol group. In the propofol group, patients were anesthetized with a single use of propofol. In the fentanyl group and butorphanol group, a combination of fentanyl and propofol was administered. Basic information, evaluation of anesthesia effects, changes of vital signs, incidence of complications, and Visual Analogue Scale (VAS) scores for uterine contraction pain were collected and analyzed. Results: Butorphanol and fentanyl groups demonstrated superior anesthetic effects over the propofol group (P<0.001), but no significant differences were found between the former two groups (P=0.064). Butorphanol group consumed the least propofol, compared to the other two groups (115.91 ± 21.70 mg, P<0.01), and recovery time (14.00 ± 1.35 min) was a bit longer than the fentanyl group (P=0.0015) and propofol group (12.61 ± 1.91, P=0.2416), although the latter difference was not significant. Hypotension in the fentanyl group was obvious and incidence (48.5%) was higher than in propofol (P=0.009) and butorphanol groups (30.3%, P=0.131). Incidence of dizziness was also higher in fentanyl group, compared with the other two groups (P=0.007), while drowsiness occurred most frequently in the butorphanol group (P=0.000). Changes in vital signs were maximal in fentanyl group and minimal in the propofol group. Uterine contraction pain after surgery was most severe in propofol group (P=0.003) and slightest in the butorphanol group (P<0.01) when discharged. Conclusion: This present study provides evidence for selecting proper analgesics in induced abortion. Butorphanol is more suitable for stabilizing vital signs and preventing uterine contraction pain than fentanyl, during and after the operation.
Optimal PSS Tuning by using Artificial Bee Colony

This paper addresses a new optimization technique namely artificial bee colony (ABC) algorithm for power system stabilizer (PSS) design. In the proposed methodology, PSS is considered with a conventional structure and its parameters are tuned by using ABC algorithm. A two areas power system containing uncertainties is considered as case study to evaluate the proposed method. Besides, non linear simulations are carried out to show the accuracy of results. Time domain simulation results clearly verify that the proposed technique enhances the dynamic stability of the system considering uncertainties.
Social Media Analytics using Data Mining By Hibatullah Alzahrani

There is a rapid increase in the usage of social media in the most recent decade. Getting to social media platforms for example, Twitter, Facebook LinkedIn and Google+ via mediums like web and the web 2.0 has become the most convenient way for users. Individuals are turning out to be more inspired by and depending on such platforms for data, news and thoughts of different clients on various topics. The substantial dependence on these social platforms causes them to produce huge information described by three computational issues in particular; volume, velocity and dynamism. These issues frequently make informal organization information exceptionally complex to break down physically, bringing about the related utilization of computational method for dissecting
Detection of Deception

A meta-analysis was conducted of research on the relation between judges' accuracy at detecting deception and their confidence in their judgments. A total of 18 independent samples revealed an average weighted accuracy-confidence correlation of . 04, a relation not significantly differentfrom zero. However, confidence waspositively correlated with judges' tendency to perceive messages as truthful, regardless of the actual truthfulness ofthe messages. Judges were also more confident when they really
Inverse synthetic aperture radar image reconstruction with heavily corrupted data based on heavy-tailed Lévy model

Abstract. Inverse synthetic aperture radar (ISAR) is a powerful radar-processing technique that uses target’s motion to generate images on the range-Doppler plane. In the defense industry, ISAR imaging of moving targets is an important tool for automatic target recognition. We focus on the problem of ISAR imaging at low signal-to-noise ratio (SNR). The nonsubsampled directional filter bank (NSDFB) is a very useful tool in analyzing the directional information in two-dimensional signals. This paper presents an ISAR Imaging algorithm using NSDFB coefficients modeling. Bayesian maximum a posteriori is used where the heavy-tailed Lévy model is assumed for estimating an ISAR image at low SNR. We applied NSDFB transform to the ISAR image and developed a simulation procedure to describe the characteristics of the algorithm. Both simulated and real ISAR data have been tested. The proposed algorithm maintains a balance among noise suppression, feature preservation, and computational time. Finally, the experiments show that the proposed method outperforms others in terms of visual evaluation and image assessment parameters.
Local frames

In this paper we introduce the concept of a local Hilbert space frame and develop theory for the representation and reconstruction of signals using local frames. The theory of global frames is due to Duffin and Schaeffer. Local frames are defined with respect to a global frame and a particular element from a Hilbert space H. For any signal f* (epsilon) H, H may be decomposed into two signal dependent subspaces: a finite dimensional one which essentially contains the signal f* and one to which the signal is essentially orthogonal. The frame elements associated with the former subspace constitute the local frame around f*.
High [18F]FDG Uptake in Primary Cerebral Lymphoma: A PET Study

Two cases of primary intracranial malignant lymphoma with high uptake of [18F]fluorodeoxyglucose ([18F]FDG) are reported. Malignant lymphomas should be considered in the differential diagnosis of brain tumors with high [18F]FDG uptake in positron emission tomography studies.
