Temporal profiles of physical activity and energy expenditure in cancer in-patients

Fifty-three cancer in-patients (37 males and 16 females) were randomly selected from the Regional Cancer Center, Pt. J.N. M. College, Dr. B.R. Ambedkar Hospital, Raipur, India. Rhythms in physical activity (PA) and energy expenditure (EE) were studied non-invasively using Actical (Mini Mitter Co. Inc., USA) and compared with 24 apparently healthy subjects (11 males and 13 females). Data were gathered at 1-min epoch length for at least three to four consecutive days and were analyzed using several statistical techniques, such as Cosinor rhythmometry, ANOVA, Duncan's multiple-range test, and t-test. Most of the cancer in-patients and all control subjects exhibited a statistically significant circadian rhythm in PA and EE. However, the rhythm detection ratio was low among cancer in-patients. Patients had significantly lower 24-h average, lower amplitude, and an earlier acrophase in PA and EE rhythms. Further, significant effect of factor disease was discerned on total activity count (TAC) and total energy expenditure (TEE). TAC and TEE were significantly lower in cancer in-patients as compared to control subjects, irrespective of gender. In addition, a gradual decrement in PA intensity levels from sedentary to vigorous was validated in patients. From the present findings, it can be concluded that the factor disease might alter the temporal profiles of the PA and EE. However, further intensive studies involving more patients are required to reinforce the above conclusion.
Children's Affiliation with Nature

This paper examines the biophilia hypothesis p:it forth by E. 0. Wilson, which asserts the existence of a fundamental, genetically-based human need and propensity to affiliate with other living organisms and lifelike processes. It reviews research by Wilson and others that supports the biophilia hypothesis, and examines some of the issues and concerns that are at the forefront of the debate over the validity of the biophilia hypothesis. The paper then draws on structural-developmental psychological theory to expand Wilson's hypothesis in order to address perceived flaws in Wilson's original hypothesis. Finally, the paper discusses three studies conducted in the United States and the Brazilian Amazon on children's moral and ecological conceptions of the natural environment. The studies were found to support a structural-developmental account of biophilia. (Contains 65 references.)

Stem/progenitor cells in the developing human liver: morphological and immunohistochemical features

Stem/progenitor cells in the adult liver are able to differentiate both into hepatocyte and cholangiocyte lineage. The identification and the role of human liver stem/progenitor cells has been a challenge topic in the recent scientific literature. The existence of stem/progenitor cells in the liver was first claimed in experimental animal models. CD34, c-kit, cytokeratin 7, cytokeratin 19, α-fetoprotein, OV6 and CD90 were the first markers shown. The major support for the existence of hepatic stem/progenitor cells has come from studies on liver carcinogenesis, human liver disease and cirrhosis. Where exactly the putative stem/progenitor cells reside in the normal liver is still controversial and their specific anatomical location is still unclear. Preliminary data from our lab indicate the portal tracts as the preferential site of the stem cell niches thanks to the expression of biliary-type cytokeratin 19, SOX9 and c-kit. Small undifferentiated cells were easily identified in H&E as well. Like in other organs, hepatic stem/progenitor cell niche was hypothesized and described as composed of numerous cell types that interact and cross-talk with hepatic stem/progenitor cells. Hepatic stem/progenitor cells represent a heterogeneous population with a spectrum of morphological and immunohistochemical features ranging from bile duct cells to hepatocytes, including the multipotent hepatic stem/progenitor cells, the hepatoblasts, the committed progenitors and the diploid adult cells. Inside this complex and articulate spectrum, cells without hepatobiliary markers and hematopoietic stem/progenitor cells can be identified. The hepatic stem/progenitor cells exhibit specific population functions and can be identified by specific population immunohistochemical markers, including CD133, CXCR4, SOX9, SOX17, cytokeratins, Hedgehog proteins, MDR1 and many others. In conclusion, this study represents the basis for further studies, aimed at better characterizing these stem/progenitor cells and at identifying possible subtypes of hepatic stem progenitor cells.

A pair of CO + He white dwarfs as the progenitor of 2005E-like supernovae?

Context. Ca-rich transients (CRTs, 2005E-like supernovae) exhibit unusually strong Ca features during their nebular phase, and their distribution in their host galaxies indicates that they belong to a metal-poor old population. A pair of low-mass CO + He white dwarfs (WD) has been suggested to be the progenitor of CRTs. A helium shell is accumulated onto the CO WD by accretion, and then a helium-shell detonation is ignited when the helium shell reaches a critical mass, which could lead to the second detonation in the center of the CO WD. Aims. Taking the birth rate of CRTs into consideration, we examine whether and if yes, which type of low-mass CO + He WD pairs fulfill the constraints of being of an old population and of the birth rate derived from observations. Methods. We carried out a series of binary population syntheses and present four different channels in which CO + He WD pairs can be formed. We selected the systems that fulfill the constraints of being of an old population and of the birth rate from all the CO + He WD pairs by constraining the component mass of the WD pairs. Results. For the four channels, the stable Roche lobe overflow (RLOF) could significantly influence the formation of the WD pairs. Based on their position on the M-CO-M-He plane, the mass-transfer between the components for most of the CO + He WD pairs is neither always unstable nor always stable. We found that it is necessary that the CO WDs are less massive than 0.6 M-circle dot and the He WDs are less massive than 0.25 M-circle dot if CO + He WD pairs are to fulfill the constraints of being of an old population and of the birth rate of CRTs. However, the He WD mass is lower than the ejecta mass of the CRTs derived from observations, while the total mass of the low-mass WD pairs is higher than this. Conclusions. Our results imply that the CO WDs participate in CRT explosions and at the same time, a bound remnant could be left after the CRT explosion if the low-mass WD pairs are the progenitors of CRTs. Therefore, it needs to be examined whether or not the helium detonation on a low-mass CO WD may lead to the second detonation in the center of the CO WDs, and whether or not the bound remnant is left after the thermonuclear explosion.

Getting the picture : the role of external representations in simulation-based inquiry learning

Three studies were performed to examine the effects of formats of ‘pre-fabricated’ and learner-generated representations on learning outcomes of pupils learning combinatorics and probability theory. In Study I, the effects of different formats on learning outcomes were examined. Learners in five experimental conditions were provided with a simulation-based learning environment. The experimental manipulation concerned the format of the simulations. These were diagrammatical, arithmetical, textual, a combination of textual+arithmetical or diagrammatical+arithmetical. The main finding of the study is that learning from the textual+arithmetical format was most beneficial, in particular with regard to procedural knowledge. Diagrams were found to negatively affect learning and to increase cognitive load. In Studies II and III learners had to work through the same kind of learning environment as in Study I, but they also had to construct representations themselves. The experimental manipulation concerned the format of the representation: graphical (concept map), arithmetical, or textual. In Study II the participants worked alone. It was found that the concept-map and the textual format afforded the creation of domain representations more than the arithmetical format. It was also found that learners engaging in the construction of representations showed higher learning outcomes. This could not be attributed to prior knowledge. Study III was identical except that participants worked in dyads. Again, the concept map and the textual format afforded the creation of representations more than the arithmetical format, although here no differences with regard to learning outcomes were observed between dyads engaging in representation construction and dyads that did not.
Integration of African indigenous guidance practices to adolescents' pastoral care and counselling programmes in selected churches of Nairobi

The purpose of this study was threefold. First, to find out the pastoral counseling given to adolescents in selected Nairobi churches. Second, to assess the element(s) of African indigenous counseling techniques already incorporated in the pastoral counselling techniques. Third, to examine the sources of guidance utilized by adolescents. Through purposive sampling method, seven churches in Nairobi from the main denominations in Kenya were selected for research. These are the Consolata Shrine Westlands.The Kings Church Githurai Kimbo, The African Church of The Holy Spirit (ACOHS) Pumwani, Chrisco City Church, Kenya Assemblies of God (Bahati), Riruta Baptist Church, African Independent Pentecostal Church of Africa (AIPCA) Dandora and the Salvation Army Kibera. Basic methods ofact finding were utilized. The subject respondents included adolescents, pastoral workers, parents of adolescents and key leaders of sampled churches. In total, a sample of 160 respondents were interviewed from population approximately not less than 10, 400 church attendees. The data for the study were collected through the use of questionnaires, participant observation and analysis of documents from library sources. The overall data were collated, analyzed, interpreted and discussed in the light of Erickson's theory of identity and development. The theory shows that unless the adolescents grow holistically, they would result to social deviancy observed through withdrawal, fanaticism and rejection of cultural standards or give a passive stand that brings role confusion. The research findings revealed that adolescents in Nairobi were having unresolved problems and concerns such as boy/girl relationships, drug abuse and anxiety about bodily changes. In spite of this, the methods utilized by the pastoral workers in giving guidance in the seven churches, did not effectively help resolve adolescents' problems. The study recommends that for churches to be able to guide adolescents more effectively, church leaders need to look into issues such as establishing a good rapport with adolescents, training lay church workers specifically on the needs of the youth and creating ample time and space for adolescents' needs. The leaders will also need to identify with the seclusion camp model suggested in the study so as to guide and counsel adolescents in a more relevant manner. This would help stabilize the adolescent's inner person that craves for identity and recognition.
Best proximity points of local contractive mappings on metric spaces endowed with binary relation

The aim of this paper is to present best proximity point results of (α -η;ψ)- proximal mappings satisfying local contractive conditions on a closed ball in the framework of complete metric spaces. An example is also presented to validate the result proved herein. As an application of our results, we prove existence of best proximity points of locally contractive mappings in the frame work of metric spaces endowed with binary relation. Our results extend and generalize various comparable results in the existing literature.
Convergence Analysis for Rectangular Matrix Completion Using Burer-Monteiro Factorization and Gradient Descent

We address the rectangular matrix completion problem by lifting the unknown matrix to a positive semidefinite matrix in higher dimension, and optimizing a nonconvex objective over the semidefinite factor using a simple gradient descent scheme. With $O( \mu r^2 \kappa^2 n \max(\mu, \log n))$ random observations of a $n_1 \times n_2$ $\mu$-incoherent matrix of rank $r$ and condition number $\kappa$, where $n = \max(n_1, n_2)$, the algorithm linearly converges to the global optimum with high probability.
The Imprint of Cosmic Reionization on the Luminosity Function of Galaxies

The (re)ionization of hydrogen in the early universe has a profound effect on the formation of the first galaxies: by raising the gas temperature and pressure, it prevents gas from cooling into small halos, thus affecting the abundance of present-day small galaxies. Using the Galform semi-analytic model of galaxy formation, we show that two key aspects of the reionization process—when reionization takes place and the characteristic scale below which it suppresses galaxy formation—are imprinted in the luminosity function of dwarf galaxies. We focus on the luminosity function of satellites of galaxies like the Milky Way and the LMC, which is easier to measure than the luminosity function of the dwarf population as a whole. Our results show that the details of these two characteristic properties of reionization determine the shape of the luminosity distribution of satellites in a unique way, and are largely independent of the other details of the galaxy formation model. Our models generically predict a bimodality in the distribution of satellites as a function of luminosity: a population of faint satellites and population of bright satellites separated by a “valley” forged by reionization. We show that this bimodal distribution is present at high statistical significance in the combined satellite luminosity function of the Milky Way and M31. We make predictions for the expected number of satellites around LMC-mass dwarfs where the bimodality may also be measurable in future observational programs. Our preferred model predicts a total of 26 ± 10 (68% confidence) satellites brighter than MV = 0 in LMC-mass systems.
Neonatal pleural effusions in a Level III Neonatal Intensive Care Unit

Pleural effusions are rare in the newborn. Still, being familiar with this condition is relevant given its association with a wide range of disorders. Only two large series of cases on this matter have been published, with no solid conclusions established. The aim of this study is to determine the etiology, management and prognosis of pleural effusions in a population of high-risk neonates. The authors performed a retrospective study in the Neonatal Intensive Care Unit of “Hospital de Sao Joao”, Porto (Portugal), between 1997 and 2014, of all newborns with the diagnosis of pleural effusion, chylothorax, hemothorax, empyema, fetal hydrops or leakage of total parenteral nutrition (TPN). Eighty-two newborns were included, 48 males and 34 females. Pleural effusions were congenital in 19 (23.2%) newborns and acquired in 63 (76.8%). Fetal hydrops was the most frequent cause (15 cases, 78.9%) of congenital effusions while postoperative after intrathoracic surgery was the most common cause (39 cases, 61.9%) of acquired effusions, followed by leakage of TPN (13 cases, 20.6%). Chylothorax was the most common type of effusion (41.5% of cases). Pleural effusions after intrathoracic surgery were mainly (64.1%) chylothoraces. Regarding use of octreotide for treatment of acquired chylous effusions, the comparative analysis showed no statistical differences between the group of alive newborns who received octreotide and the group who did not. Twenty-seven (32.9%) newborns died; the causes of death were related to underlying diseases and not to the pleural effusion. Clinical outcome is generally good, except in hydropic neonates. Blood albumin level appears to be predictive of prognosis and further investigation on its clinical significance should be encouraged.
Industrial liaison and academic entrepreneurship in Wales

This paper summarises findings on the practices and perceptions of industrial liaison in four universities within the federal University of Wales system in the UK. The research, part of the European Union Targeted Socio-Economic Research Programme study on ‘Universities, Technology Transfer and Spin-Off; Academic Entrepreneurship in European Regions’, involved surveys and interviews with both Industrial Liaison Officers (ILOs) and academics in receipt of their services and non-users. Broadly speaking ILO activity tends to be reactive and administrative. Academics consider, often mistakenly, that ILO work should be more commercial, as well as pressing for it to be even more strongly market-orientated
Gran Telescopio Canarias OSIRIS transiting exoplanet atmospheric survey: detection of potassium in XO-2b from narrowband spectrophotometry

We present Gran Telescopio Canarias (GTC) optical transit narrow-band photometry of the hot-Jupiter exoplanet XO-2b using the OSIRIS instrument. This unique instrument has the capabilities to deliver high cadence narrow-band photometric lightcurves, allowing us to probe the atmospheric composition of hot Jupiters from the ground. The observations were taken during three transit events which cover four wavelengths at spectral resolutions near 500, necessary for observing atmospheric features, and have near-photon limited sub-mmag precisions. Precision narrow-band photometry on a large aperture telescope allows for atmospheric transmission spectral features to be observed for exoplanets around much fainter stars than those of the well studied targets HD 209458b and HD 189733b, providing access to the majority of known transiting planets. For XO-2b, we measure planet-to-star radius contrasts of Rpl/R? =0.10508 0.00052 at 6792 A, 0.10640 0.00058 at 7582 A, and 0.10686 0.00060 at 7664.9 A, and 0.10362 0.00051 at 8839 A. These measurements reveal signicant spectral features at two wavelengths, with an absorption level of 0.067
Investigating the Prevalence of Renal Artery Stenosis Following Coronary Artery Angiography and Related Risks in Hypertensive Patients Candidate for Coronary Artery Angiography in Yazd Afshar Hospital

Introduction : Renal artery stenosis is the most prevalent disease of renal artery and has an important role in making hypertension and renal atrophy. Since in previous researches, despite high frequency of risk of cardiovascular disease in Iran, there did not exist any general research investigating risk factors of coronary artery disease and incidence of contemporary renal artery stenisis, this study intended to investigate these factors in hypertensive patients in Iran. Methods: This cross-sectional study was performed on 264 patients who were hypertension candidate for coronary artery angiography in Afshar hospital in Yazd. At the time of coronary angiography, patients had renal angiography at the same time. Among those patients, those who had coronary artery disease were selected and thus prevalence and severity of renal artery stenosis and its relationship with cardiovascular risks were investigated. The gathered data were analyzed by Spss-18 software. Results: Prevalence of renal artery stenosis (equal and over 50%) was 38.25 in all patients; in other words, in men and women it was 43.56% and 56.44% (P=0.04) respectively. Prevalence of co-morbidity of coronary artery disease and renal artery stenosis with 1 vessel disease was 34%, 2 vessel disease was 57.14% and 3 vessel disease was 54.17% with significant differences (P<0.01) Conclusion: According to high prevalence of renal artery stenosis in hypertensive patients and high prevalency with simultaneous hypertension and coronary artery disease, renal angiography after coronary angiography may assist for unknown renal artery stenosis and better treatment.
Cone penetration testing in the clay tills of Skåne - An investigation of the cone factor

The undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt), relating the two quantities is, therefore, needed. The Swedish Geotechnical Institute suggests to use a cone factor of 11 when using CPT in the clay tills of Skane. However, in Denmark, a value of 10 is recommended for similar soils. The magnitude of the calibration factor is critical when determining the undrained shear strength and, consequently, for further design. To investigate the cone factor, measurements of the undrained shear strength and the net cone resistance were compared for five types of clay till found in Skane at a total of three different sites. Depending on availability, other soil parameters were considered in the analysis in order to explain variations of the calibration factor Nkt. The comparison between the undrained shear strength measurements, from field vane tests, and the net cone resistance gave a mean value of Nkt in the range of 9.3 to 10.2. However, a significant standard deviation, ranging from 0.7 to 1.7, is connected to the evaluated cone factors. Due to the significant degree of scatter in the data, partially caused by the inhomogeneous nature of the soil and partially influenced by primarily using field vane tests to evaluate the undrained shear strength, it is hard to draw exhaustive conclusions. However, for the different soils studied in this project, it seems reasonable to use a cone factor lower than 11. It also appears that the cone factor is closely linked to the overconsolidation ratio, though more tests at various locations are needed to verify this hypothesis.
