An examination of evoked K‐complex amplitude and frequency of occurrence in the elderly

The elderly consistently display lower levels of slow wave sleep (SWS), primarily because of the small amplitude of their delta activity. Given that delta electroencephalogram (EEG) and K‐complexes are thought to be generated by the same mechanisms, it was hypothesized that K‐complex amplitude and rate of production would be lower in the elderly. K‐complex amplitude was assessed by averaging K‐complex responses to auditory stimuli, and measuring the amplitude of the N550 component of the averaged evoked response. Ten young (five males and five females; mean age 23.10 ± 5.36 years) and 10 elderly adults (six males and four females; mean age=75.60 ± 4.48 years) who were neurologically healthy and free from medication spent two non‐consecutive nights in the sleep laboratory. EEG was recorded from six gold plate electrodes (Fz, Fcz, Cz, Cpz, Pz and O2) referenced to A1 + A2. Tone clicks (1000 Hz), of varying intensity from 70 to 100 decibels above measured awake detection threshold, were presented binaurally during stage 2 sleep. Responses were classified according to whether they produced: a K‐complex, a vertex sharp wave (VSW), both of these responses or neither response. They were then averaged separately for each response type. The elderly showed a substantially smaller N350 (averaged VSWs) and N550 amplitudes compared with the young subjects. The elderly also showed an augmented but delayed P2 component, followed by a long‐lasting positive EEG shift. The smaller amplitude of the averaged K‐complex N550 component is consistent with lower delta amplitudes previously reported in the elderly and with the hypothesis that K‐complexes and delta activity share the same generator mechanisms. The enhanced P2 component and the long‐lasting positive deflection in the EEG in the elderly indicate the existence of age differences other than smaller EEG amplitude.
Paradigms for Parallel Computation

Message passing, as implemented in message passing interface (MPI), has become the industry standard for programming on distributed memory parallel architectures, while the threading on shared memory machines is typically implemented in OpenMP. Outstanding performance has been achieved with these methods, but only on a relatively small number of codes, requiring expert tuning, particularly as system size increases. With the advent of multicore/manycore microprocessors, and continuing scaling in the size of systems, an inflection point may be nearing that will require a substantial shift in the way large scale systems are programmed to maintain productivity. The parallel paradigms project was undertaken to evaluate the nearterm readiness of a number of emerging ideas in parallel programming, with specific emphasis on their applicability to applications in the user productivity enhancement and technology transfer (PET) electronics, networking, and systems/C4I (ENS) focus area. The evaluation included examinations of usability, performance, scalability, and support for fault tolerance. Applications representative of ENS problems were ported to each of the evaluated languages, along with a set of ldquodwarfrdquo codes representing a broader workload. In addition, a user study was undertaken where teaching modules were developed for each paradigm, and delivered to groups of both novice and expert programmers to measure productivity. Results was presented from six paradigms currently undergoing ongoing evaluation. Experiences with each of these models was presented, including performance of applications re-coded across these models and feedback from users.
Genetic and environmental contributions to dimensions of personality disorder.

OBJECTIVE The authors estimated the heritability of the basic dimensions of personality disorder and the relative proportions of the variance attributable to genetic and environmental sources. METHOD The subjects were 175 volunteer twin pairs (90 monozygotic and 85 dizygotic) from the general population. Each twin completed the Dimensional Assessment of Personality Pathology, a questionnaire that assesses 18 dimensions of personality disorder. The questionnaire was developed on the basis of factor analytic studies that identified a stable structure underlying personality disorders in clinical and nonclinical subjects. Structural equation model-fitting methods were used to estimate the influence of additive genetic, common environmental, and unique environmental effects. RESULTS The estimates of broad heritability ranged from 0%, for conduct problems, to 64%, for narcissism. Behaviors associated with submissiveness and attachment problems had low heritability. For most dimensions, the best-fitting model was one that specified additive genetic and unique environmental effects. CONCLUSIONS These results are similar to those reported for normal personality and suggest a continuity between normal and disordered personality.
Plasma gonadotropin concentrations and ovarian characteristics in Inverdale ewes that are heterozygous for a major gene (FecX1) on the X chromosome that influences ovulation rate.

Ewes heterozygous (I+) for the Inverdale prolificacy gene (FecX1) located on the X chromosome have ovulation rates approximately 1.0 times higher than noncarriers (++). The aims of this study were to examine, in I+ and ++ ewes, the peripheral plasma concentrations and/or ovarian secretion rates of FSH, LH, inhibin, estradiol, and progesterone during anestrus and the estrous cycle and after ovariectomy. Also examined were aspects of ovarian morphology and functions of granulosa cells in vitro. No FecX1-specific differences were noted for the ovarian hormones or for FSH or LH. However, I+ animals contained significantly more ovarian antral follicles (p < 0.05) and their granulosa cells had a higher mean LH responsiveness in vitro with respect to cAMP synthesis at smaller follicular diameters relative to ++ ewes (I+ = > 2.5 mm; ++ = > 4.5 mm). Moreover, nonatretic follicles in I+ animals compared to the ++ genotype contained fewer granulosa cells and smaller CL. Although the I+ animals had a higher ovulation rate than the controls (p < 0.05), the total weight of CL was not different between the genotypes. These findings suggest that the FecX1 gene affects ovarian function without altering ovarian hormone secretion. The findings also suggest that there are no FecX1-specific differences in the mean concentrations of gonadotropins, although further studies on temporal changes in gonadotropin secretion are warranted.
HOPE-Trial: Hemiarthroplasty Compared with Total Hip Arthroplasty for Displaced Femoral Neck Fractures in Octogenarians

Background: The choice of primary hemiarthroplasty or total hip arthroplasty in patients ≥80 years of age with a displaced femoral neck fracture has not been adequately studied. As the number of healthy, elderly patients ≥80 years of age is continually increasing, optimizing treatments for improving outcomes and reducing the need for secondary surgery is an important consideration. The aim of the present study was to compare the results of hemiarthroplasty with those of total hip arthroplasty in patients ≥80 years of age. Methods: This prospective, randomized, single-blinded trial included 120 patients with a mean age of 86 years (range, 80 to 94 years) who had sustained an acute displaced femoral neck fracture <36 hours previously. The patients were randomized to treatment with hemiarthroplasty (n = 60) or total hip arthroplasty (n = 60). The primary end points were hip function and health-related quality of life at 2 years. Secondary end points included hip-related complications and reoperations, mortality, pain in the involved hip, activities of daily living, surgical time, blood loss, and general complications. The patients were reviewed at 3 months and 1 and 2 years. Results: We found no differences between the groups in terms of hip function, health-related quality of life, hip-related complications and reoperations, activities of daily living, or pain in the involved hip. Hip function, activities of daily living, and pain in the involved hip deteriorated in both groups compared with pre-fracture values. The ability to regain previous walking function was similar in both groups. Conclusions: We found no difference in outcomes after treatment with either hemiarthroplasty or total hip arthroplasty in active octogenarians and nonagenarians with a displaced femoral neck fracture up to 2 years after surgery. Hemiarthroplasty is a suitable procedure in the short term for this group of patients. Level of Evidence: Therapeutic Level I.

Body condition score and milk fatty acids as indicators of dairy cattle reproductive performances

Improving cow fertility by means of genetic selection has become increasingly important over the last years in order to overcome the decline in dairy cow fertility that has taken place over the past decades. However, fertility traits are difficult to measure and have low heritabilities. Consequently, indicator traits are of interest for breeding value estimation for fertility especially if these traits are easier to measure, have higher heritabilities and are well correlated with fertility. Therefore, the objective of this thesis was to investigate the opportunity of using either fatty acid contents (FA) in milk predicted by mid-infrared spectrometry or body condition score (BCS; i.e., a subjective measure of the amount of metabolizable energy stored in a live animal) as indicator traits of female fertility. Research conducted on BCS and fertility records from Canadian Ayrshire and Holstein cows indicated that BCS was heritable and showed a low to moderate favorable genetic correlation with fertility suggesting that higher BCS would be related to better fertility. Also, based on results obtained on Walloon data, selection for higher nadir BCS was suggested as useful to change BCS curve over the lactation and improve fertility. Furthermore, using records from Walloon Holstein cows, FA were demonstrated to be moderately heritable. Genetic correlations among FA and fertility were low to moderate and changed over the lactation. Overall, the pattern of genetic correlations of fertility with BCS and FA substantiated the known relationship between energy balance status and fertility. Body fat mobilization in early lactation induces BCS loss. Also, the release of long-chain FA in milk from the body fat mobilization inhibits de novo FA synthesis in the mammary gland, leading to a decrease of shortand mediumchain FA. To conclude, this research has shown that traits based on BCS and milk FA profile fulfill criteria to be considered as indicator traits to improve indirectly fertility of dairy cows.

The Sloan Digital Sky Survey Quasar Catalog. III. Third Data Release

We present the third edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of the 46,420 objects in the SDSS Third Data Release that have luminosities larger than Mi = -22 (in a cosmology with H0 = 70 km s-1 Mpc-1, ΩM = 0.3, and ΩΛ = 0.7), have at least one emission line with FWHM larger than 1000 km s-1 or are unambiguously broad absorption line quasars, are fainter than i = 15.0, and have highly reliable redshifts. The area covered by the catalog is ≈4188 deg2. The quasar redshifts range from 0.08 to 5.41, with a median value of 1.47; the high-redshift sample includes 520 quasars at redshifts greater than 4, of which 17 are at redshifts greater than 5. For each object the catalog presents positions accurate to better than 0. ″2 rms per coordinate, five-band (ugriz) CCD-based photometry with typical accuracy of 0.03 mag, and information on the morphology and selection method. The catalog also contains radio, near-infrared, and X-ray emission properties of the quasars, when available, from other large-area surveys. The calibrated digital spectra cover the wavelength region 3800–9200 Å at a spectral resolution of ≃2000; the spectra can be retrieved from the public database using the information provided in the catalog. A total of 44,221 objects in the catalog were discovered by the SDSS; 28,400 of the SDSS discoveries are reported here for the first time.
The Relationship between Perceived Teachers' Self-Disclosure and Out-of-Classroom Communication among Malaysian Undergraduates in a Private Institution of Higher Learning.

This quantitative study was conducted to determine whether a significant relationship exists between perceived teachers’ self-disclosure and students’ out of classroom communication with teachers in a Malaysian private institution of higher learning. A survey consisting of two questionnaires, namely the Perceived Teacher’s Self-Disclosure scale designed by Cayanus and Martin (2008) as well as Knapp and Martin’s (2002) Out-of-Classroom Communication Scale were collected from 144 final year undergraduates from a Malaysian private institution of higher learning. Using the SPSS, the Pearson product-moment correlation coefficient, independent-samples t-test and one-way between-groups ANOVA with post-hoc tests were used to analyze the data. The findings indicated a positive relationship between the dimensions of amount and relevance in perceived teachers’ self-disclosure and students’ out of classroom communication. There was no significant difference recorded between gender, with perceived teachers’ self-disclosure and students’ out of classroom communication. Besides, there was also no significant difference recorded between age, with perceived teachers’ self-disclosure and students’ out of classroom communication. The study concludes that Malaysian undergraduates’ perceptions towards teachers’ self-disclosure influences the out of classroom communication with teachers.
Biomagnification and polychlorinated biphenyl congener distribution in an aquatic predator‐prey, host‐parasite system

Biomagnification and polychlorinated biphenyl (PCB) congener distribution was examined in a predator‐prey, hostparasite system, in which Atlantic salmon (Salmo salar) preyed upon sprat (Sprattus sprattus). Eubothrium crassum was an intestinal parasite in salmon that also “preyed upon” sprat, because the parasites gained access to foodstuffs via the host (salmon) gut. Salmon contained significantly higher concentrations of total PCBs compared to both parasites and prey (sprat), but no difference in PCB concentration was found between sprat and E. crassum. Salmon biomagnified several PCB congeners from their diet (sprat), whereas parasites did not, despite the fact that both salmon and their parasites ingested the same prey. Differences in nutrient uptake mechanisms between the host and their parasites, in addition to the lack of a gastrointestinal tract in the cestode, may explain the lack of biomagnification in E. crassum. No difference was found in PCB congener distribution between parasites, salmon, and sprat, and none of the animal types showed a preference for accumulating more or less lipophilic congeners (congeners with a high or low octanol/water partition coefficient [KOW]). Biomagnification factors for individual congeners in salmon did not increase with KOW; rather, they were constant, as shown by a linear relationship for congener concentration in prey and predator.
Impact of Work Life Balance on Organizational Commitment of University Teachers: Evidence from Jashore University of Science and Technology

Increased imbalance between work and family life of university teachers is an alarming issue now-a-days. The purpose of this study is to investigate the relationship between work life balance and organizational commitment of teaching employees of Jashore University of Science and Technology in Bangladesh. Data has been collected from 80 respondents through a questionnaire survey. Pearson correlation and regression model have been developed based on this dataset to get the result. The result shows that significant number of teachers perceived there is a positive impact of work life balance on the level of commitment towards their organization. This study certainly answers the question regarding the impact of work life balance on organizational commitment of the teaching employees. Moreover, further studies are encouraged to analyze the impact of work life balance by incorporating all the stakeholders of an organization which may help to generalize the findings of this study.
Responses of squirrel monkeys to seasonal changes in food availability in an eastern Amazonian forest

Tropical forests are characterized by marked temporal and spatial variation in productivity, and many primates face foraging problems associated with seasonal shifts in fruit availability. In this study, I examined seasonal changes in diet and foraging behaviors of two groups of squirrel monkeys (Saimiri sciureus), studied for 12 months in Eastern Brazilian Amazonia, an area characterized by seasonal rainfall. Squirrel monkeys were primarily insectivorous (79% of feeding and foraging time), with fruit consumption highest during the rainy season. Although monkeys fed from 68 plant species, fruit of Attalea maripa palms accounted for 28% of annual fruit‐feeding records. Dietary shifts in the dry season were correlated with a decline in ripe A. maripa fruits. Despite pronounced seasonal variation in rainfall and fruit abundance, foraging efficiency, travel time, and distance traveled remained stable between seasons. Instead, squirrel monkeys at this Eastern Amazonian site primarily dealt with the seasonal decline in fruit by showing dietary flexibility. Consumption of insects, flowers, and exudates increased during the dry season. In particular, their foraging behavior at this time strongly resembled that of tamarins (Saguinus sp.) and consisted of heavy use of seed‐pod exudates and specialized foraging on large‐bodied orthopterans near the forest floor. Comparisons with squirrel monkeys at other locations indicate that, across their geographic range, Saimiri use a variety of behavioral tactics during reduced periods of fruit availability. Am. J.

IL-10 enhances CTL-mediated tumor rejection by inhibiting highly suppressive CD4+ T cells and promoting CTL persistence in a murine model of plasmacytoma

Interleukin-10 (IL-10) is a potent anti-inflammatory cytokine that regulates immune responses. IL-10 has also been shown to enhance antitumor CD8+ T-cell responses in tumor models although the underlying mechanisms are not fully understood. In this study, we used a series of genetic mouse models and the mouse plasmacytoma J558 model to investigate this issue. J558 tumors grew significantly faster in IL-10−/− mice than in wild type (WT) mice, but similarly in IL-10−/−Rag2−/− and Rag2−/− mice. Tumors from IL-10−/− mice contained fewer IFN-γ-producing CD8+ and CD4+ T cells than tumors from WT mice. Strikingly, depletion of total CD4+ T cells, but not CD25+ cells, resulted in tumor eradication in IL-10−/− mice. Adoptive transfer studies revealed that CD4+ T cells from IL-10−/− mice exhibited more potent suppression of cytotoxic T lymphocyte (CTL)-mediated tumor rejection than their WT counterparts, and IL-10–deficient tumor-infiltrating CD4+ T cells expressed higher levels of PD-L1 and CTLA-4 inhibitory molecules. Although IL-10–deficient CD8+ T cells are not defective in activation and initial rejection of tumors, adoptive transfer studies using IL-10–deficient P1CTL transgenic T cells that recognize the tumor rejection antigen P1A reveal that IL-10 is required for long-term persistence of CTLs and control of tumor growth. Thus, we have found that IL-10 enhances antitumor CTL responses by inhibiting highly suppressive CD4+ T cells and promoting CTL persistence. These data have important implications for the design of immunotherapy for human cancer.
(2,2′-Bipyridine-κ2 N,N′)[2-tert-butylanilinato(2−)]dichloridooxidomolybdenum(VI) dichloromethane hemisolvate

The MoVI atom in the title structure, [Mo(C10H13N)Cl2O(C10H8N2)]·0.5CH2Cl2, has a distorted octahedral coordination sphere with cis-orientated oxide and imide ligands, trans-chloride ligands and the 2,2′-bipyridine (bipy) ligand N atoms lying trans to the oxide and imide ligands. An imide-ligand tert-butyl-methyl-group H atom makes a close approach with the oxide ligand (distance = 2.53 Å) and the imide-ligand N atom (distance = 2.41 Å). Another imide-ligand tert-butyl-methyl-group H atom makes a close approach to a chloride ligand (distance = 2.82 Å). One bipy-ligand α-H atom makes a close approach to the oxide ligand (distance = 2.4 Å) and the other α-H atom makes a close approach to the imide-ligand phenyl-ring ortho-H atom (distance = 2.52 Å). These close approaches suggest the presence of weak intramolecular hydrogen bonds. The solvent molecule has been modelled under consideration of half-occupancy.
Nutrition of fig (Ficus carica L.) under hydroponics and greenhouse conditions

Abstract In this investigation the extraction curve of macronutrients (N, P, K, Ca, Mg) and micronutrients (Fe, Cu, Zn and Mn) were determined in the cultivation of fig. A system of intensive production of fig in greenhouse and hydroponics was established with 1.25 plants m−2. The determination of the nitrogen content was done by the micro-Kjeldahl method. The P was by the yellow molybdovanadate method throughon a spectrophotometer. The K was determined by flamometry and the Ca, Mg, Fe, Cu, Zn and Mn were determined by atomic absorption spectrophotometry. Of the organs analyzed, the stem was the that accumulated more dry matter, then, the leaves and finally the fruits. The nutrient extraction dynamics presented similar upward behavior in all nutrients. The demand for macronutrients in decreasing order was N > K > P > Ca > Mg and for the micronutrients Cu > Fe > Mn > Zn.
