of vitamin B12. Moreover, if some vitamin B12 is destroyed in the gastro-intestinal tract with the liberation of free ions of cobalt, it is possible that some of the latter might be absorbed as such. Some of our patients with pernicious anaemia seem to have absorbed a fraction of the radioactive vitamin B12, and this may indicate, as Goldhamer (1936) first suggested, that some patients with pernicious anaemia secrete traces of intrinsic factor. The significance of our figures depends chiefly on the accuracy of the stool collections. Experience in this department with radioactive iron (Fe59), which was given by mouth and recovered from the red blood corpuscles and from the faeces, supports the view that incompleteness of stool collection is unlikely to account for all the radioactivity which was not recovered.
Vision Based Displacement Detection for Stabilized UAV Control on Cloud Server

Nowadays, image processing solution is used in many fields such as traffic information systems and illegal intrusion detection systems. Now, to assist with the control of camera-equipped devices, appropriate image processing techniques are needed for moving rather than fixed observers. For achieving this goal, an algorithm should derive the desired results quickly and accurately; thus, this paper considers two characteristics: functional performance (reliability) and temporal performance (efficiency). Reliability means how well the desired results can be achieved, and efficiency means how quickly the result can be calculated. This paper suggests an optimized real-time image algorithm based on the integration of the optical flow and Speeded-Up Robust Features (SURF) algorithms. This algorithm determines horizontal or vertical movement of the camera and then extracts its displacement. The proposed algorithm can be used to stabilize an Unmanned Aerial Vehicle (UAV) in situations where it is drifting due to inertia and external forces, like wind, in parallel. The proposed algorithm is efficient in achieving drift stabilization by movement detection; however, it is not appropriate for image processing in small UAVs. To solve this problem, this study proposes an image processing method that uses a high-performance computer.
Observations on the early renal uptake and later tubular metabolism of radiolabelled aprotinin (Trasylol) in man: theoretical and practical considerations.

1. The novel method recently developed to measure renal tubular degradation of filtered proteins in man using radiolabelled aprotinin (Trasylol) has been modified to allow the fate and the significance of the renal catabolism of radiolabelled aprotinin to be determined beyond 24h. 2. Ten renal patients with normal kidney function and variable proteinuria each received two separate intravenous injections of radiolabelled aprotinin, 5.0 mg of 99mTc-labelled aprotinin (40MBq) and 0.5mg of 131I-labelled aprotinin (5MBq). Chromatography (Sephadex-G-25-M) was used to separate undegraded radiolabelled aprotinin from the free isotope in urine and plasma. Renal uptake from gamma-camera images (24h for 99mTc-labelled aprotinin and up to 96h for 131I-labelled aprotinin) and urinary activity (48 and 96h, respectively) were measured. 3. The renal handling of radiolabelled aprotinin was similar with the two isotopes. Chromatography showed that all plasma activity was undegraded radiolabelled aprotinin, and urine activity was only the free isotopic label. 4. Kidney uptake of 131I-labelled aprotinin was prompt, reaching a cumulative maximum of 37.1 +/- 3.0% of dose at 24h, but falling exponentially thereafter to 5.6 +/- 1.0% of dose at 96h. 5. The rate of excretion of the free label in urine, i.e. the metabolic rate of radiolabelled aprotinin, was relatively constant over the first 24h (1.6 +/- 0.09% of dose/h), but then fell in parallel with the diminishing activity over the kidney, i.e. to 1.0 +/- 0.1% of dose/h over 24-48h and to only 0.4 +/- 0.08% of dose/h over 72-96h.

Analysis of CD161 expression on human CD8+ T cells defines a distinct functional subset with tissue-homing properties

CD8+ T lymphocytes play a key role in host defense, in particular against important persistent viruses, although the critical functional properties of such cells in tissue are not fully defined. We have previously observed that CD8+ T cells specific for tissue-localized viruses such as hepatitis C virus express high levels of the C-type lectin CD161. To explore the significance of this, we examined CD8+CD161+ T cells in healthy donors and those with hepatitis C virus and defined a population of CD8+ T cells with distinct homing and functional properties. These cells express high levels of CD161 and a pattern of molecules consistent with type 17 differentiation, including cytokines (e.g., IL-17, IL-22), transcription factors (e.g., retinoic acid-related orphan receptor γ-t, P = 6 × 10−9; RUNX2, P = 0.004), cytokine receptors (e.g., IL-23R, P = 2 × 10−7; IL-18 receptor, P = 4 × 10−6), and chemokine receptors (e.g., CCR6, P = 3 × 10−8; CXCR6, P = 3 × 10−7; CCR2, P = 4 × 10−7). CD161+CD8+ T cells were markedly enriched in tissue samples and coexpressed IL-17 with high levels of IFN-γ and/or IL-22. The levels of polyfunctional cells in tissue was most marked in those with mild disease (P = 0.0006). These data define a T cell lineage that is present already in cord blood and represents as many as one in six circulating CD8+ T cells in normal humans and a substantial fraction of tissue-infiltrating CD8+ T cells in chronic inflammation. Such cells play a role in the pathogenesis of chronic hepatitis and arthritis and potentially in other infectious and inflammatory diseases of man.
The log-Gabor method: speech classification using spectrogram image analysis

We explored the suitability of the log-Gabor method, a speech analysis method inspired by Ezzat e.a. (2007), for automatic classification of personality and likability traits in speech. The core idea underlying the log-Gabor method is to treat the spectrogram as an image of spectro-temporal information. The image is transformed into Gabor energy values using the twodimensional logarithmic Gabor transform, which is a standard feature extraction method in visual texture analysis. The aggregated energy values are mapped onto classes by means of a support vector machine (SVM). The log-Gabor method performed above baseline on the INTERSPEECH Personality and Likability Sub-Challenges Development sets and comparable to baseline for the Test sets. These results support further investigation of the log-Gabor method as a method for extracting perceptual cues from speech.
Association between Chronic Obstructive Pulmonary Disease and Coronary Artery Disease

Introduction: Both Chronic obstructive pulmonary disease (COPD) and coronary artery disease (CAD) are global epidemics, each affecting in excess of 10 million patients. Both conditions co-exist at different rates and incur significant morbidity and mortality, and present major challenges to healthcare providers. In the developing world the prevalence of CAD is increasing but the prevalence of COPD is unknown. This study was designed to estimate the proportion of patients with CAD who have concomitant COPD and identify factors that may increase the likelihood of COPD in CAD patients. Materials and Methods: A cross sectional study that included 100 consecutive patients of CHD attending the Medicine OPD of the LTMMC Sion and BYL Nair hospital fulfilling the inclusion and exclusion criteria were selected for study. All the patients underwent spirometry using an electronic spirometer. COPD was diagnosed using GOLD classification. Results were analysed using SPSS ver. 19. Results: The mean age (SD) of study subjects was 48.3 (7.7) years. Of the 100 patients; 19 had COPD as per the GOLD classification. COPD was significantly more among patients with severe cardiac dysfunction, smokers and age above 60 years (p < 0.01). Conclusion: In this group of patients with CAD about one in five has concomitant COPD. This will have enormous burden on health expenditure in a region where health budgets are already strained by costs of compacting endemic diseases. The prevalence rate we recorded warrants routine screening of all CAD patients for
More Money into the Medical Sector: Is This the Answer?

This paper questions the conventional assumption that additional resources are the best way of improving the quality of care provided under a nation's health service. It also challenges the proposition that some diseases will always remain simply too expensive to treat. It is pointed out that the proportion of health care concerned with life and death situations is extremely small, and that the total needs related with these aspects of medical care are quite limited. Extensive evidence is quoted to the effect that in other aspects of medical treatment, dealing with chronic progressive illness and with relatively trivial disease, there is substantial misuse of resources. This arises primarily because the present patterns of morbidity and of demand for medical care have not yet been fully appreciated. In addition, administrative inefficiency has added to the wasteful use of resources. The paper argues that it is only in the caring aspects of medicine, as opposed to its preventive and curative aspects, that the potential scope for improvement in quality of care is virtually unlimited.
Mining Assessment and Teaching Evaluation Data of Regular, Advanced Stream Students

This paper investigates the effect of the stream (regular or advanced) on the student evaluation of teaching and the course marks. It presents a case study in a third year Computer Science course at an Australian university. The results show that there were no significant differences between the two groups in their perception of teaching and learning. However, the two groups significantly differed in their assessment results in all assessment components and also in the most important predictors of the final mark. _______________________________________________________________________
Increased FOXP3 expression in small-bowel mucosa of children with coeliac disease and type I diabetes mellitus

Objective. To determine whether the expression of FOXP3 is changed in small-bowel mucosa in coeliac disease (CD). Material and methods. The study comprised 52 patients (mean age 8.01±6.14 years) who had undergone small-bowel biopsies. CD only was diagnosed in 16 patients, and CD with type I diabetes mellitus (T1D) in 7. These 23 patients and 4 others without CD had partial or subtotal villous atrophy (PVA, SVA). Twenty-five persons without CD had normal mucosa. The transcription level of the FOXP3 gene (Hs00203958_m1) was evaluated in biopsy samples (small bowel) using TaqMan gene expression assays. FOXP3 protein in mucosal cells was evaluated with mouse anti-human FOXP3 antibodies and CD25+, and CD4+ T cells were evaluated by mouse monoclonal antibodies. Results. Expression of FOXP3 mRNA was higher in both PVA and SVA compared to normal mucosa (p=0.007). Patients with CD and T1D had higher expression of FOXP3 mRNA than patients with CD alone (p=0.02). The number of FOXP3+ cells in intestinal mucosa was higher in patients with CD, especially those with coexisting T1D, than in those with normal mucosa (p=0.01). The results of double staining showed that, among all positive cells, FOXP3 expression alone was revealed in 25.6% of the cells, CD25 positivity in 18% and both markers simultaneously were found in 56.5% of lymphocytes (p=0.03). Double staining for CD4 and FOXP3 showed that 87.5% of cells were CD4+, 2.8% were FOXP3+ and 9.7% of cells simultaneously expressed the CD4 and FOXP3 markers. Conclusions. A more pronounced expression of FOXP3 mRNA and also the number of FOXP3+ cells (with simultaneous expression of CD25 and CD4 markers) were found in the small-bowel biopsy specimens obtained from children with CD, particularly those with coexisting T1D, compared with the FOXP3 expression in normal mucosa.
Multicast capacity analysis for social-proximity urban bus-assisted VANETs

Capacity scaling laws of wireless networks have attracted a lot of attention. In this paper, we study the multicast capacity of bus-assistant VANETs (vehicular ad hoc networks) with two-hop relay scheme, which has not been addressed before. Assume that n ordinary vehicles and nb buses are deployed in a grid-like road framework while the number of roads increase linearly with n. All the ordinary vehicles obey the restricted mobility model. Thus, the spatial stationary distribution decays as power law with the distance from the centre spot (home-point) of a restrict region of each vehicle. All the buses deployed in all roads as intermediate nodes. They are used to forward packets for ordinary vehicles. Each ordinary vehicle randomly chooses k - 1 vehicles from the other ordinary vehicles as receivers. The packets could be transmitted directly from source to destination or be transmitted to an intermediate vehicle or bus, then be forwarded to the destination. We found that the social-proximity urban bus-assisted VANET has three routing methods. For each routing method, we derive the matching asymptotic upper and lower bounds of multicast capacity of bus-assisted VANET.
West Nile Virus Infection Rates in Culex nigripalpus (Diptera: Culicidae) Do Not Reflect Transmission Rates in Florida

Abstract We describe the first documented field transmission of West Nile (WN) virus by a North American mosquito. WN was first detected in northern Florida in 2001. An intensive mosquito trapping and surveillance program was conducted in this region for four nights to assess mosquito transmission of WN. Four mosquito traps, each with a single sentinel chicken, were placed at five different locations on each of four nights. A total of 11,948 mosquitoes was collected, and 14 mosquito pools were found to contain WN, giving a minimum infection rate between 1.08 and 7.54 per 1,000. Only one of the 80 sentinel chickens seroconverted to WN, demonstrating a single mosquito transmission event during the study and a mosquito transmission rate of between 0.8 and 1 per 1,000. Culex nigripalpus Theobald was responsible for WN transmission to the sentinel chicken, although both Cx. nigripalpus and Culex quinquefasciatus Say were found infected with WN. Mosquito transmission rates are reported in this study for the first time for a WN outbreak. This information is essential to determine risk of human and animal infection.
Value of Mobile Phones for Tanzanian University Students

Mobile phones have become highly popular both in industrialised and developing world. In developing countries, previous studies of why people value mobile phones have focused on the financial benefits of mobile phone and user groups such as farmers or entrepreneurs. This paper presents a mixed-method study on how university students in Iringa, Tanzania value mobile phones. The study discovered a number of positive and negative value factors that define the worth of mobile phones for Tanzanian students, and shows how the factors are tied to the physical, social and cultural context of use. The study highlights the importance of understanding what users value and why when designing technology.
Comparison of dietary supplement product knowledge and confidence between pharmacists and health food store employees.

OBJECTIVES To determine pharmacists' and health food store employees' knowledge about the safety and efficacy of common, nonvitamin, nonmineral dietary supplements in a retail setting and confidence in discussing, recommending, and acquiring knowledge about complementary and alternative medicine (CAM). DESIGN Cross-sectional survey. SETTING Central and western New York in May and June 2012. MAIN OUTCOME MEASURES Knowledge and confidence survey scores based on true/false and Likert scale responses. RESULTS Pharmacists' mean knowledge score was significantly higher than that of health food store employees (8.42 vs. 6.15 items of 15 total knowledge questions). Adjusting for differences in experience, education, occupation, and confidence, knowledge scores were significantly higher for pharmacists and those with a higher total confidence score. Pharmacists were significantly less confident about the safety and efficacy of CAM comparatively (13 vs. 16 items of 20 total questions). CONCLUSION Pharmacists scored significantly higher than health food store employees on a survey assessing knowledge of dietary supplements' safety and efficacy. Despite the significant difference, scores were unacceptably low for pharmacists, highlighting a knowledge deficit in subject matter.
Acute toxicity of zinc, copper and lead to three species of marine organisms from the Sinop Peninsula, Black Sea*

Acute toxicity tests were performed on Echinogammars olivii (Amphipoda), Sphaeroma serratum (Isopoda) and Palaemon elegans (Decapoda), from the Sinop Peninsula in the Black Sea. 96- h LC 50 values were estimated for copper, zinc and lead in these species using the static bioassay method. The LC 50 values of Cu for E. olivii, S. serratum and P. elegans were 0.25, 1.98 and 2.52 mg/l, respectively. The LC 50 values of Zn for E. olivii , S. serratum and P. elegans were 1.30, 6.12 and 12.3 mg/l, respectively. The LC 50 values of Pb for E. olivii, S. serratum and P. elegans were 0.62, 4.61 and 5.88 mg/l, respectively. The results indicated that Cu was more toxic to the species followed by Pb and Zn. E. olivii was more sensitive to the metals than S. serratum and P. elegans.
Million Song Dataset Recommendation Project Report

For our project, we decided to experiment, design and implement a song recommendation system. We used the Million Song Dataset [1] (MSDS) to find correlations between users and between songs to ultimately provide recommendations for songs to which users would prefer to listen. In this paper, we will discuss the problems we faced, the methods we considered to implement this system, and the results and analysis of our findings. We have also compared our findings with other experiments done in the field. From our findings, also we recognize numerous ways to improve the results of our recommendation system; we believe we have found a novel way to recommend songs that a user might enjoy.
Risk factors for preterm birth: a New Zealand study.

AIM To identify risk factors for preterm birth. METHODS A cross sectional study. The study population was 1800 infants selected randomly from all babies born over a three-year period. Of these, 85 (4.8%) were classified preterm (less than 37 completed weeks gestation). Data were collected from obstetric records and parental interviews. RESULTS Risk factors associated with an increased risk of preterm birth after controlling for potential confounders included smoking during pregnancy (adjusted relative risk (RR) = 2.7, 95% confidence interval (CI) = 1.3, 5.4), and multiple birth (adjusted RR = 48.8, 95% CI = 18.1, 131.4). Urinary tract infection was significant at the 7% level (adjusted RR = 2.3, 95% CI = 1.0, 5.6). Alcohol intake in third trimester was associated with a reduced risk of preterm birth (adjusted RR = 0.4, 95% CI = 0.2, 0.7). CONCLUSION Maternal smoking and multiple births were the most important modifiable risk factors in this study for preterm birth and may contribute to 17% and 11% of preterm births respectively.
Characterization of antibodies to sporozoites in Plasmodium falciparum malaria and correlation with protection

The antibody response to sporozoites of Plasmodium falciparum and the role of these antibodies in protection against malaria have not been systematically investigated. An understanding of antisporozoite antibodies in natural infection is, however, important to the development of a human malaria vaccine. In a prospective study in Thailand, an antibody response to sporozoites was observed only in individuals who developed parasitemia. Antibodies were detected against an epitope in the repeat region of the circumsporozoite (CS) protein. Current candidate sporozoite vaccines are based on CS repeat antigens. The CS antibody response was of low magnitude, peaked after detection of parasitemia, and had a serum half-life of less than 1 month. CS antibody boosting occurred in only 6% of reinfected individuals. These observations suggest that antisporozoite antibody is poorly developed under natural conditions and appears not to protect against development of malaria.
Ferromagnetic p-d exchange in Zn1-xCrxSe diluted magnetic semiconductor.

We measured free exciton splitting and Faraday rotation of the diluted magnetic semiconductor ${\mathrm{Zn}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Cr}}_{\mathit{x}}$Se (x0.005) and found valence band splitting which is reversed relative to the materials with Mn, Co, or Fe. This fact indicates a ferromagnetic p-d exchange, observed for the first time in II-VI diluted magnetic semiconductors.
Crystallite Size Dependence on Structural Parameters and Photocatalytic Activity of Microemulsion Mediated Synthesized Zno Nanoparticles Annealed at Different Temperatures

The synthesis of ZnO nanoparticles has attracted considerable interest because of their unique properties and potential applications in a variety of solid state devices, catalytic media etc. By using water-in-oil (w/o) microemulsions, nanodroplets of water were used as chemical reactor to synthesize nanoparticles of zinc oxide. Addition of reducing agent ((NH4)2CO3) and zinc salt (Zn(NO3)2) followed by heat treatment results in the formation of zinc oxide nanoparticles (NPs). The structural and optical properties of the samples were investigated by X-ray diffraction and UV-VISNIR absorption spectroscopy. X-ray diffraction revealed the wurtzite structure of ZnO. Percentage of lattice contraction and average particle size of the sample were also calculated from the XRD. Size-dependent blue shifts of absorption spectra revealed the quantum confinement effect. Furthermore, on increasing annealing temperature of ZnO NPs, crystallize size increases which, in turn,decreases the band gap energy and photocatalytic degradation efficiency of phenol.
