Pengaruh senam lansia terhadap derajat depresi pada lansia di panti werda

Abstract : Depression is a serious medical illness with mood, cognitive, and physical symptoms. Mood symptoms include depressed, sad, or irritable mood; loss of interest in usual activities; inability to experience pleasure; feelings of guilt or worthlessness; and thoughts of death or suicide. Cognitive symptoms include inability to concentrate and difficulty in making decisions. Physical symptoms include fatigue, lack of energy and changes in sleep, appetite, and activity levels. Geriatric depression is more severe than depression in other groups of age, where it causes depressive symptomps to 15% elderly. This study was carried out to identify the impact of Senam Lansia on the degree of depression in elderly. This is an experimental study that was conducted to 18 participants that live in Senja Cerah Hospice Manado. The degree of depression was assessed using Hamilton Depression Rating Scale. This 8-weeks senam-lansia-intervented study found a positively moderate and significant impact of Senam Lansia on the degree of depression in elderly (r = 0,594; p < 0,05). Futhermore, Senam Lansia has a positive impact on participants’ activities of daily living (ADL) such as increasing mobility and appetite, decreasing muscle fatigue, and developing positive feelings such as happy, healthy, fresh and fit.

Fragile X Syndrome: Prevalence, Treatment, and Prevention in China

Fragile X syndrome (FXS) is the most common inherited cause of intellectual disability and the leading monogenic cause of autism spectrum disorder. Although FXS has been studied for several decades, there is relatively little basic science or clinical research being performed on FXS in China. Indeed, there is a large gap between China and Western countries in the FXS field. China has a potentially large number of FXS patients. However, many of them are underdiagnosed or even misdiagnosed, and treatments are not always administered in the Chinese population. This review discusses the prevalence, treatment, and prevention of FXS in China to facilitate an understanding of this disease in the Chinese population.
MONOCLONAL ANTIBODY TO THE SECOND lgE Fc RECEPTOR Washed human platelets

Several characteristics of human eosinophil heterogeneity in some diseases associated with eosinophilia have been reported. They concerned eosinophil morphology with reduced numbers of granules and increased membrane receptors (1), cell density, and cytotoxic functions (2) or metabolism (3). The more interesting topic related to this point is the functional role of these altered eosinophils in human pathology, as suspected in a variety of diseases characterized mainly by cardiac or lung injury (4). Our previous works showed that the presence of receptors for IgE (FcE receptors), directly involved in the effector function of human eosinophils against IgE-coated parasite targets, was restricted to a subpopulation of eosinophils (5). This eosinophil subpopulation of abnormally low density, named for this reason "hypodense" (2), was only present in the blood of highly hypereosinophilic patients (eosinophil counts >3,000/mm 3) or in the tissues, mainly in some cases of lung diseases (6). In addition, a recent report indicating that pulmonary eosinophils could kill lung parenchymal cells (7), suggested a particularly effective function of these eosinophils, not only in antiparasite cytotoxicity but also in various pathological situations. Like eosinophils, human platelets were discovered to be effector cells against schistosomula ofSchistosoma mansoni, in vitro and in vivo, in the presence of IgE antibodies (8). Both mechanisms of killing involved Fce receptors, which bind IgE immunoglobulins with a relatively low affinity (9). Antigenic similarities between FceR of eosinophils and platelets were suggested by the parallel inhibition of both IgE-dependent cytotoxicity and IgE binding, with polyclonal antibodies also able to inhibit Fc~R on human lymphocytes and monocytes (5, 9-1 1). The original aim of this study was to prepare an mAb specifically directed against the bypodense subpopulation of human eosinophils in order to obtain a phenotypic marker that could characterize and quantify these cells both in the blood and tissues of hypereosinophilic patients. Moreover, since recent data suggested that these hypogranular cells were activated in vivo (6), the presence
Digital radiology using active matrix readout of amorphous selenium: theoretical analysis of detective quantum efficiency.

A flat-panel x-ray imaging detector using a layer of amorphous selenium (a-Se) for direct conversion of x rays (to charge) and an active matrix for self-scanned readout is being investigated for digital radiology. A theoretical analysis of the spatial frequency dependent detective quantum efficiency (DQE(f)) of the self-scanned a-Se detector is performed based on a model of signal and noise propagation in a cascaded imaging system. Because of the high intrinsic resolution of a-Se and the pixelated active matrix readout method, such detectors are inherently undersampled and aliasing is present. The presampling modulation transfer function (MTF) and aliased noise power spectrum (NPS) of the detector were used in the analysis of DQE(f). It is proven that the aliased NPS for the self-scanned a-Se detectors is white. Since the shape of DQE(f) is determined by the ratio of MTF squared and the NPS, the shape of DQE(f) follows the square of the presampling MTF of the detector as a result of the white NPS. The analysis also shows that DQE(0) is proportional to the pixel fill factor, i.e., the fraction of each pixel area used for image charge collection. The DQE analysis is applied to detector parameters for three x-ray imaging applications: mammography, chest radiography, and fluoroscopy. The effects of pixel fill factor, imaging geometry (i.e., incident angle of x rays), and various sources of electronic noise on the detector DQE(f) are discussed. Strategies for maximizing detector DQE for each x-ray imaging application are proposed.

Oxidative Stress in Erythrocytes from Premature and Full-term Infants During their First 72 h of Life

Objective : The aim of this study was to evaluate the extent of lipid peroxidation and the response of the enzymatic and non-enzymatic antioxidant defence system in erythrocytes from full-term and premature infants at birth, after 3 and after 72 h of life. Study design: Twenty infants were selected and divided in two groups according to their gestational age. Blood samples were taken at birth, at 3 and at 72 h of life, erythrocytes were isolated and the following parameters were measured: fatty-acid profile, coenzyme Q, f -tocopherol, hydroperoxides and the activity of the antioxidant enzymes catalase, superoxide dismutase (SOD) and cytosolic glutathione peroxidase (cGPx). Results: For the three studied periods, several differences between full-term and premature infants were found. Premature children showed a higher concentration of hydroperoxides, a lower level of f -tocopherol and lower SOD and cGPx activity (except for cGPx at birth). Moreover, n-3 polyunsaturated fatty-acids percentages (essential for good neonatal development) were higher in full term children throughout all the study. Conclusion: Results suggest a strong imbalance between oxidants and antioxidants in premature infants during their first 72 h of life, a situation which could lead to several pathologies. Therefore, further research is needed, including possible nutritional intervention (with antioxidant therapy, supplementation of essential fatty acids and other dietary constituents) before and after birth.
Computer Games versus Maps before Reading Stories: Priming Readers' Spatial Situation Models

The current study investigated how computer games and maps compare as preparation for readers to comprehend and retain spatial relations in text narratives. Readers create situation models of five dimensions: spatial, temporal, causal, goal, and protagonist (Zwaan, Langston, & Graesser 1995). Of these five, readers mentally model the spatial dimension least well (Rinck, 2005). Studying maps before reading improves retention of general details from non-narrative readings (Kulhavy & Stock, 1996). The current study investigated how playing interactive computer games compared with studying a computer-based map as a preparation for reading a narrative. The dependent variables were: 1) evidence of monitoring spatial relations while reading stories, and 2) comprehension and retention of spatial relations in stories. Evidence of monitoring of the spatial relations was measured by average times, in milliseconds, for reading individual sentences with changes in protagonist location. Comprehension and retention of spatial relations in stories were measured by multiple-choice posttests of spatial relations in the stories. Eighty 11-year-olds participated in all three experimental conditions: 1) studying a map with sound and animations but no interaction, 2) playing an interactive computer game, and 3) completing a filler task. Each condition was followed by reading a narrative and then taking a spatial posttest. In terms of multiple-choice posttests, map condition had the highest average number correct, closely followed by the computer game. Filler task condition was a distant third. No between-condition differences were found for the reading times on sentences with changes in protagonist location. Results suggest that maps may be superior to computers games as preparation for spatial reading.
Optimizing the Nominal Introduction Rule in (Hyper)Tableau Calculi

A tableau calculus for SHIQ has been known for some time, and it forms the basis for several highly successful implementations [2, 9, 10]. Extending this calculus to SHOIQ, however, was notoriously difficult due to an interaction between nominals, inverse roles, and number restrictions, which results in (partial) loss of the forest-model property for models of SHOIQ knowledge bases. In this paper, we analyze the problems that arise from this combination of features and present an overview of two solutions. The first solution, described in [4], extends the SHIQ calculus with an NNrule that extends the non-forest-like portion of a model with new individuals. Applications of this rule can be highly nondeterministic, however, and can substantially increase the size of the generated models, which can lead to inefficiency. We present an alternative solution based on a new NI-rule. Our approach does not introduce new individuals; instead, existing individuals are incorporated into the non-forest-like portion of the model. We implemented our solution in HermiT. As we discuss in [8], this approach seems to work well in practice.
Efficient Estimation of Spatially Varying Subsurface Scattering Parameters

We present an image-based technique to efficiently acquire spatially varying subsurface reflectance properties of a human face. The estimated properties can be used directly to render faces with spatially varying scattering, or can be used to estimate a robust average across the face. We demonstrate our technique with renderings of peoples’ faces under novel, spatially-varying illumination and provide comparisons with current techniques. Our captured data consists of images of the face from a single viewpoint under two small sets of projected images. The first set, a sequence of phase-shifted periodic stripe patterns, provides a per-pixel profile of how light scatters from adjacent locations. The second set of structured light patterns is used to obtain face geometry. We subtract the minimum of each profile to remove the contribution of interreflected light from the rest of the face, and then match the observed reflectance profiles to scattering properties predicted by a scattering model using a lookup table. From these properties we can generate images of the subsurface reflectance of the face under any incident illumination, including local lighting. The rendered images exhibit realistic subsurface transport, including light bleeding across shadow edges. Our method works more than an order of magnitude faster than current techniques for capturing subsurface scattering information, and makes it possible for the first time to capture these properties over an entire face.
Mapping next generation learning spaces as a designed quality enhancement process

Abstract The learning spaces of higher education are changing with collaborative, agile and technology-enabled spaces ever more popular. Despite the massive investment required to create these new spaces, current quality systems are poorly placed to account for the value they create. Such learning spaces are typically popular with students but the impact they have on learning outcomes is difficult to capture. Taking a design-research approach, this paper presents a way of assessing the value of learning spaces in context through systematically mapping the expectations reified in their designs. While presenting a series of specific tools that support this mapping exercise, this paper also contributes to a larger conversation about the sorts of tools and processes the academic community might use in accounting for the quality of its work.
A Parametric Analysis of Rehearsal Opportunities During Training of Functional Analysis Conditions

The purpose of the current studies was to evaluate the use of rehearsal during training on the fidelity of functional analysis conditions. Study 1 used a parametric analysis of the number of rehearsal opportunities to examine the effects on the fidelity with which participants implemented three functional analysis conditions. One, three, and 10 rehearsals were examined, which were counterbalanced across three undergraduate participants. Next, participants experienced additional rehearsals until they met criterion. On average, participants met criterion after 7.6 rehearsals (4, 5.7, and 13 rehearsals for the one, three, and 10 rehearsal conditions, respectively). Study 2 incorporated a video model to evaluate the effects of the number of rehearsal opportunities with a behavioral skills training package with 18 undergraduate participants. Results indicate the addition of the video model decreased the average number of rehearsals (M = 6.3) necessary to meet criterion by just over one and a half rehearsals (3.5, 4.8, and 11.5 rehearsals for the one, three, and 10 rehearsal conditions, respectively) compared to Study 1. A training acceptability survey suggested rehearsal with feedback was more acceptable than instructions and the full behavioral skills training package was highly acceptable.
Predicting short and long-term exercise intentions and behaviour in patients with coronary artery disease: A test of protection motivation theory

The purpose of this study was to examine the utility of protection motivation theory (PMT) in the prediction of exercise intentions and behaviour in the year following hospitalisation for coronary artery disease (CAD). Patients with documented CAD (n = 787), recruited at hospital discharge, completed questionnaires measuring PMT's threat (i.e. perceived severity and vulnerability) and coping (i.e. self-efficacy, response efficacy) appraisal constructs at baseline, 2 and 6 months, and exercise behaviour at baseline, 6 and 12 months post-hospitalisation. Structural equation modelling showed that the PMT model of exercise at 6 months had a good fit with the empirical data. Self-efficacy, response efficacy, and perceived severity predicted exercise intentions, which, in turn predicted exercise behaviour. Overall, the PMT variables accounted for a moderate amount of variance in exercise intentions (23%) and behaviour (20%). In contrast, the PMT model was not reliable for predicting exercise behaviour at 12 months post-hospitalisation. The data provided support for PMT applied to short-term, but not long-term, exercise behaviour among patients with CAD. Health education should concentrate on providing positive coping messages to enhance patients’ confidence regarding exercise and their belief that exercise provides health benefits, as well as realistic information about disease severity.
Deciding the Existence of a Time-Sharing Ability: A Combined Methodological and Theoretical Approach

Experimental and statistical methods for examining individual differences in dual-task performance and time-sharing ability are reviewed and criticized. Previous data and analysis procedures are generally inadequate to evaluate a time-sharing ability. Errors resulting from unsophisticated use of correlational and factor analytic procedures are described. Four previous studies that concern time-sharing are considered in detail. The nature of task selection, scoring methods, and control of practice and reliability issues are discussed. Based on a reanalysis of available data, a time-sharing ability is not rejected. Simulation, incorporation of theory in planning models, and crucial tests of the hypotheses are proposed as methods for assessing the time-sharing ability.
Cyclin I and p53 are differentially expressed during the terminal differentiation of the postnatal mouse heart

In this study, we have used Ki‐67 and MF20 mAb to determine how extensively cardiomyocytes proliferate in the postnatal mouse heart. It was established that the cardiomyocytes divided rapidly in 2‐day‐old hearts. However, at 13 days, the majority of cardiomyocytes had entered into terminal growth arrest and differentiation. We exploited this finding in order to identify proteins that were associated with cardiomyocyte growth and differentiation. The protein profiles of 2‐ and 13‐day‐old hearts were established by two‐dimensional electrophoresis and compared. Seventeen protein spots were found to be differentially expressed at day 13. Eight of them were up‐regulated while the remaining nine protein spots were down‐regulated. We focused our attention on 2 of the proteins identified by MALDI‐TOF MS, cyclin I and p53, because they are both believed to be involved in cell cycle regulation. Western blot analysis confirmed that both proteins were positively up‐regulated in the 13‐day‐old postnatal heart. To determine directly whether these proteins were associated with cell proliferation, we examined their expression patterns in H9c2 cardiomyocytes maintained in vitro. We established that cyclin I expression was low during the growing phase of H9c2 culture and high during the growth arrest/differentiation phases. In contrast, p53 expression was unchanged during both phases. The various growth phases were confirmed by the presence of cyclin A and growth arrest‐specific 1 proteins. We investigated whether silencing cyclin I expression using cyclin I‐siRNA could promote an increase in H9c2 cell proliferation. It was determined that silencing cyclin I could enhance a small, but significant, increase in H9c2 cell division. Similar results were obtained for cardiomyocytes extracted from 13‐day‐old hearts. These results imply that the reason why cardiomyocytes in 13‐day‐old hearts increased cyclin I expression was probably associated with terminal growth arrest. However, the increase in p53 expression was probably associated with cardiomyocyte differentiation, rather than growth arrest.
Faculty as Contributors to Learning for Native American Students

With a national sample of 700 Native American students who took the National Survey of Student Engagement (NSSE), this study tested the ways faculty interaction and inclusion of diverse perspectives in the classroom contributed to learning for Native American students. Significant predictors of learning were quality academic advising, faculty interactions that were supportive, instructor feedback that enabled students to work hard to meet expectations, and coursework that emphasized analysis, application, and diverse perspectives.
