Assessment of a Remedial Community College Cohort for Multiple Intelligences.

According to a 1996 study by the National Center for Education Statistics, 75%. of America's colleges offer remedial courses and 29% of first-time freshmen take them. Community colleges typically spend more on remedial education than do four-year institutions, and they are anticipating increased demand for such programs. The study cites Howard Gardner, who identified eight different intelligences--musical, kinesthetic, mathematical, spatial, linguistic, interpersonal, intrapersonal, and naturalist. Gardner argues that Multiple Intelligences (MI) offers an intelligence fair means to consider an individual's potential. The purpose of this study was threefold: (1) to identify the dominant domains, specific skills, and predominant intellectual styles of remedial community college students using the Multiple Intelligences Developmental Assessment Scales (MIDAS) instrument; (2) to determine whether statistically significant differences exist among students in their identification of a particular dominant domain, specific skill, or intellectual style in regard to the variables of gender, age, and ethnicity; and (3) to determine whether there were statistically significant differences between teachers and students in their identification of dominant MI domains. Data was compiled from responses from 81 students in remedial classes at College of the Redwoods in California. Highlights of data analysis include: Women rated themselves higher in seven out if the eight MI domains; men rated themselves higher only in the kinesthetic domain; no significant differences were shown between minority and white students.

Lack of the H-NS Protein Results in Extended and Aberrantly Positioned DNA during Chromosome Replication and Segregation in Escherichia coli

ABSTRACT The architectural protein H-NS binds nonspecifically to hundreds of sites throughout the chromosome and can multimerize to stiffen segments of DNA as well as to form DNA-protein-DNA bridges. H-NS has been suggested to contribute to the orderly folding of the Escherichia coli chromosome in the highly compacted nucleoid. In this study, we investigated the positioning and dynamics of the origins, the replisomes, and the SeqA structures trailing the replication forks in cells lacking the H-NS protein. In H-NS mutant cells, foci of SeqA, replisomes, and origins were irregularly positioned in the cell. Further analysis showed that the average distance between the SeqA structures and the replisome was increased by ∼100 nm compared to that in wild-type cells, whereas the colocalization of SeqA-bound sister DNA behind replication forks was not affected. This result may suggest that H-NS contributes to the folding of DNA along adjacent segments. H-NS mutant cells were found to be incapable of adopting the distinct and condensed nucleoid structures characteristic of E. coli cells growing rapidly in rich medium. It appears as if H-NS mutant cells adopt a “slow-growth” type of chromosome organization under nutrient-rich conditions, which leads to a decreased cellular DNA content. IMPORTANCE It is not fully understood how and to what extent nucleoid-associated proteins contribute to chromosome folding and organization during replication and segregation in Escherichia coli. In this work, we find in vivo indications that cells lacking the nucleoid-associated protein H-NS have a lower degree of DNA condensation than wild-type cells. Our work suggests that H-NS is involved in condensing the DNA along adjacent segments on the chromosome and is not likely to tether newly replicated strands of sister DNA. We also find indications that H-NS is required for rapid growth with high DNA content and for the formation of a highly condensed nucleoid structure under such conditions.
Submodular Function Maximization

Submodularity is a property of set functions with deep theoretical consequences and far– reaching applications. At first glance it appears very similar to concavity, in other ways it resembles convexity. It appears in a wide variety of applications: in Computer Science it has recently been identified and utilized in domains such as viral marketing (Kempe et al., 2003), information gathering (Krause and Guestrin, 2007), image segmentation (Boykov and Jolly, 2001; Kohli et al., 2009; Jegelka and Bilmes, 2011a), document summarization (Lin and Bilmes, 2011), and speeding up satisfiability solvers (Streeter and Golovin, 2008). In this survey we will introduce submodularity and some of its generalizations, illustrate how it arises in various applications, and discuss algorithms for optimizing submodular functions. Our emphasis here is on maximization; there are many important results and applications related to minimizing submodular functions that we do not cover.
Hilbert Space Embeddings and Metrics on Probability Measures

A Hilbert space embedding for probability measures has recently been proposed, with applications including dimensionality reduction, homogeneity testing, and independence testing. This embedding represents any probability measure as a mean element in a reproducing kernel Hilbert space (RKHS). A pseudometric on the space of probability measures can be defined as the distance between distribution embeddings: we denote this as γk, indexed by the kernel function k that defines the inner product in the RKHS. We present three theoretical properties of γk. First, we consider the question of determining the conditions on the kernel k for which γk is a metric: such k are denoted characteristic kernels. Unlike pseudometrics, a metric is zero only when two distributions coincide, thus ensuring the RKHS embedding maps all distributions uniquely (i.e., the embedding is injective). While previously published conditions may apply only in restricted circumstances (e.g., on compact domains), and are difficult to check, our conditions are straightforward and intuitive: integrally strictly positive definite kernels are characteristic. Alternatively, if a bounded continuous kernel is translation-invariant on ℜd, then it is characteristic if and only if the support of its Fourier transform is the entire ℜd. Second, we show that the distance between distributions under γk results from an interplay between the properties of the kernel and the distributions, by demonstrating that distributions are close in the embedding space when their differences occur at higher frequencies. Third, to understand the nature of the topology induced by γk, we relate γk to other popular metrics on probability measures, and present conditions on the kernel k under which γk metrizes the weak topology.
Comparative hepatotoxicity of deoxynivalenol in rat, mouse and human liver cells in culture

The present study was undertaken to assess, in vitro, the hepatotoxic potential of the food‐borne mycotoxin, deoxynivalenol (DON), using rat (Clone9 and MH1C1), mouse (NBL CL2) and human (WRL68 and HepG2) liver cells in culture. The cells were treated with DON for 24 h at 37 °C in 5% CO2 at concentrations of 0–25 µg ml−1. Following the treatment period, the cells were assayed for biochemical markers of hepatotoxicity that included three independent cytotoxicity assays, oxidative stress and mitochondrial dysfunction. Concentration‐dependent cytotoxicity of DON was observed in each of the five different liver cells derived from three different species (rat, mouse and human) over the entire concentration range studied, beginning at 0.1 µg ml−1. At these concentrations DON did not induce a biologically significant increase in oxidative stress in these liver cells, and showed a significant decrease in the mitochondrial function only in the rat liver MH1C1 cells compared with the control. The results of this in vitro study suggest that DON is a potential hepatotoxin for the rat, mouse and human liver cells in the concentration range tested in this study. The liver cells used in this study showed distinct endpoint‐sensitivity to DON related to the species. Published in 2010 by John Wiley and Sons, Ltd.
Human herpes virus type 8 seroprevalence in pregnant women in Geneva, Switzerland

Because of increasing migration, European countries are facing new pathogens and diseases, such as human herpes virus-8 (HHV-8). We assessed the prevalence of HHV-8 using a new ELISA test in 140 pregnant women delivering in Geneva (Switzerland). The prevalence of HHV-8 was 7.9% globally and up to 33.3% in the African subpopulation. Seropositive women were more frequently older (≥32 years old) than seronegative ones: 81.8% vs. 43%; p = 0.023, respectively. In conclusion, HHV-8 infection is present in European pregnant women. Attention should be given to the emergence of infectious diseases, such as HHV-8, and their impact on health in nonendemic countries.
The future of hemostasis management

We are in the midst of an unprecedented period for the development of new therapeutic products to treat patients with bleeding diseases. While current hemostatic treatments are already very effective and safe, new agents to enhance convenience and further improve both short‐ and long‐term efficacy of treatment are under development. Some of these products have already reached the clinic for early phase trials, and others will be available shortly. The strategies being evaluated for hemostatic enhancement range from gene and nucleic acid‐based approaches, to the development of complex, naturally occurring molecules such as the non‐anticoagulant polysaccharide, fucoidan. There is every likelihood that combinations of these treatment approaches will further improve the quality of bleeding disease management over the next 5 years and beyond.

Biological Properties of Staphylococcal Enterotoxin-Like Toxin Type R

ABSTRACT We investigated the biological properties of a novel staphylococcal enterotoxin-like putative toxin, staphylococcal enterotoxin-like toxin type R (SElR). Major histocompatibility complex class II molecules were required for T-cell stimulation by SElR. SElR stimulated T cells bearing receptors Vβ 3, 11, 12, 13.2, and 14. These results suggested that SElR acts as a superantigen.
Forcing Properties of Ideals of Closed Sets

Abstract With every σ-ideal I on a Polish space we associate the σ-ideal I* generated by the closed sets in I. We study the forcing notions of Borel sets modulo the respective σ -ideals I and I* and find connections between their forcing properties. To this end, we associate to a σ-ideal on a Polish space an ideal on a countable set and show how forcing properties of the forcing depend on combinatorial properties of the ideal. We also study the 1–1 or constant property of σ-ideals, i.e., the property that every Borel function defined on a Borel positive set can be restricted to a positive Borel set on which it either 1–1 or constant. We prove the following dichotomy: if I is a σ-ideal generated by closed sets, then either the forcing P1 adds a Cohen real, or else I has the 1–1 or constant property.
The knowledge and practices of oral hygiene methods and attendance pattern among school teachers in Riyadh, Saudi Arabia.

OBJECTIVE The aim of this study was to find out the knowledge and practices of oral hygiene methods among primary and secondary school teachers in Riyadh, Kingdom of Saudi Arabia (KSA). METHODS The study was carried out using a self-administered questionnaire. Four hundred and seventy teachers, male 236 (50.2%) and female 234 (48.8%) responded with a response rate of 85.5%. The study was conducted during October to December 2001 at primary and secondary schools in Riyadh City, KSA. RESULTS Almost 86% of male and 90% of female teachers felt that dental caries is due to the wrong method of tooth brushing, while sugar and sugary drinks were considered the main factor by 90% of male and 98% of female teachers. Seventy-five percent of male and 72% of female teachers considered irregular tooth brushing a cause of gums disease with 32% of male and 39% of female teachers not knowing details with regards to microbial relationship of gum disease. Tooth brushing preference was common among 45% male and 49% female teachers due to perceived effect of better cleaning, while almost an equal percentage of male and females (62%) used miswak due to Sunnah. Thirty-three point five percent of female teachers brushed 3 times a day as compared to 19% male teachers. On daily basis brushing 3 times, a day was common among >5000 SR monthly income group. Male teachers preferred horizontal tooth brushing (40%) while female teachers preferred circular tooth brushing (45%). Miswak was more commonly used by male teachers as compared to female teachers. Female school teachers had a higher income as compared to male schoolteachers. Thirty-two percent of females and 28% of male teachers were regular attendees to the dentist. Males were more satisfied by their oral health as compared to female teachers and 56% of male and 63% of female teachers visited the dentist only on having pain (toothache). CONCLUSION It is concluded that there is much resemblance in knowledge and practice of oral hygiene habits among male and female schoolteachers and there is a need to enhance their knowledge regarding oral health and disease. Both need more awareness regarding oral health promotion to have a positive role in school oral health education for their students in collaboration with oral health care workers.
The Impact of a Nitric Oxide Synthase Inhibitor (L-NAME) on Ischemia–Reperfusion Injury of Cholestatic Livers by Pringle Maneuver and Liver Resection after Bile Duct Ligation in Rats

The Pringle maneuver (PM) has been widely used to control blood loss during liver resection. However, hepatic inflow occlusion can also result in hepatic ischemia–reperfusion injury (IRI), especially in patients with a cholestatic, fibrotic, or cirrhotic liver. Here we investigate a nitric oxide synthase (NOS) inhibitor N-Nitroarginine methyl ester (L-NAME) on IRI after the PM and partial hepatectomy of cholestatic livers induced by bile duct ligation (BDL) in rats. Control group (non-BDL/no treatment), BDL + T group (BDL/L-NAME treatment) and BDL group (BDL/no treatment) were analyzed. Cholestasis was induced by BDL in the L-NAME and BDL group and a 50% partial hepatectomy with PM was performed. L-NAME was injected before PM in the BDL + T group. Hepatocellular damage, portal venous flow, microcirculation, endothelial lining, and eNOS, iNOS, interleukin (IL)-6, and transforming growth factor-β (TGF-β) were evaluated. Microcirculation of the liver in the BDL + T group tended to be higher. Liver damage and apoptotic index were significantly lower and Ki-67 labeling index was higher in the BDL + T group while iNOS and TGF-β expression was decreased. This was corroborated by a better preserved endothelial lining. L-NAME attenuated IRI following PM and improved proliferation/regeneration of cholestatic livers. These positive effects were considered as the result of improved hepatic microcirculation, prevention of iNOS formation, and TGF-β mRNA upregulation.
Studies about the low voltage ride through capabilities of variable-speed motor-generators of pumped storage hydro power plants

In order to fulfil the new challenges within power grids arising from an increasing utilization of renewable energy resources, there is an upcoming demand for pumped storage hydro power plants. Thereby, a full flexibility of active and reactive power production in generating mode as well as power consumption in pumping mode in conjunction with the best available efficiency of both electric and hydraulic devices gains in significance. Nowadays, the utilization of variable-speed pump-turbine units with either synchronous or doubly-fed asynchronous motor-generators can be applied for these tasks. Since these variable-speed units have a very different behaviour in comparison to fixed-speed synchronous machines, more detailed analyses should to be carried out in the design phase of such units. In order to achieve accurate data about steady-state as well as transient behaviour, simulation models of both mentioned arrangements are developed.
Evaluation of a new enzyme immunoassay for hepatitis C virus (HCV) core antigen with clinical sensitivity approximating that of genomic amplification of HCV RNA

The aim of this study was to analyze the clinical performance of a new enzyme immunoassay (EIA) for hepatitis C virus (HCV) core antigen in comparison with the reverse transcription polymerase chain reaction (RT‐PCR). A total of 310 patients with acute or chronic hepatitis C, and 132 HCV‐negative controls were studied. Chemiluminescence EIA with monoclonal anti‐HCV core antigen was used, and qualitative and quantitative commercial RT‐PCRs and an in‐house nested RT‐PCR were performed. Compared with nested RT‐PCR, the core antigen assay showed 97% sensitivity and 100% specificity in 75 patients with chronic hepatitis C and 132 controls. HCV core antigen was positive in 16 (94%) of 17 patients with acute hepatitis C at initial consultation. In 3 persons prospectively followed, core antigen was detected in the first available (1‐3 weeks) post‐transfusion sample. In 167 anti‐HCV–positive individuals, 129 (77%) were viremic; core antigen was detected in 126 (98%) compared with 129 (100%) for nested RT‐PCR and 121 (94%) for the commercial RT‐PCR. In 48 patients with chronic hepatitis C treated with interferon alfa, the concentration of core antigen before treatment was significantly (P < .002) lower in patients with sustained response than in nonresponders. All responders had a sustained loss of core antigen, whereas all nonresponders remained core antigen positive. The concentrations of HCV core antigen and HCV RNA correlated significantly (n = 48, r = .627, P < .001). In conclusion, the HCV core antigen assay is useful for the diagnosis of acute and chronic hepatitis C, and for predicting and monitoring the effect of interferon alfa treatment.
Peripheral Spatial Cues and Spatial Stroop Effect Can Modulate Each Other: Analyzing the Relationship between Input Selection and Dimensional Selection

The study was conducted to investigate the relationships between attentional input selection and dimensional selection by combining the peripheral cueing procedure developed by Posner with a variant of spatial Stroop task used by Funes et al (2007). The outcome showed that peripheral cueing and the spatial Stroop effect could modulate each other at short SOA but not long SOA. It is suggested that the processes that govern (a) input selection from the visual field and (b) dimensional selection from the stimulus might affect each other.
Fibroblast growth factor 23 is associated with the presence of coronary artery disease and the number of stenotic vessels

Fibroblast growth factor 23 (FGF23) has been reported to be involved in cardiovascular disease. The aim of this study was to investigate the association between FGF23 and the presence of coronary artery disease (CAD), as well as the number of stenotic vessels. A total of 254 eligible participants (167 men and 87 postmenopausal women) were enrolled in this study. Coronary angiography was used for diagnosis of CAD. Serum intact FGF23 levels were determined by a two‐sided sandwich enzyme‐linked immunosorbent assay. The median serum FGF23 levels of the entire study population were 39.9 (33.1–47.5) pg/mL. Serum FGF23 levels were higher in subjects with one‐vessel disease than those without CAD (P < 0.05), which further increased significantly in the subjects with multi‐vessel disease (P < 0.05). Serum FGF23 levels increased with cumulative number of stenotic vessels (P for trend < 0.001). Multiple stepwise regression analysis revealed estimated glomerular filtration rate (standardized β = −0.298; P < 0.001) and body mass index (standardized β = 0.132; P = 0.049) were independent factors correlated with FGF23. Multivariate logistic regression analysis showed that FGF23 was positively and independently associated with the presence of CAD (odds ratio = 1.058, 95% confidence interval = 1.025–1.092; P = 0.001). Additionally, FGF23 was also correlated with multi‐vessel disease significantly (odds ratio = 1.034, 95% confidence interval = 1.007–1.062; P = 0.013). In conclusion, serum FGF23 levels exhibit positive and independent association with the presence of CAD and increase with the cumulative number of stenotic vessels.
Allele frequency covariance among cohorts and its use in estimating effective size of age‐structured populations

A general expression for the covariance of allele frequencies among cohorts in age‐structured populations is derived. The expression is used to extend the so‐called temporal method for estimating effective population size from allele frequency shifts among samples from cohorts born any number of years apart. Computer simulations are used to check on the accuracy and precision of the method, and an application to coastal Atlantic cod is presented.
Consistency of Moderate to Vigorous Physical Activity in Middle School Physical Education

This study assessed the consistency of moderate to vigorous physical activity (MVPA) in a sample of middle school physical education lessons. Random intercept hierarchical linear regressions were employed to model the relationship between consistency of MVPA and independent variables, including lesson and teacher characteristics. Larger classes spent significantly more time in consistent MVPA in the absence of controlling for teacher characteristics. A significant interaction between class size and teacher experience suggests that experience may play a beneficial role in larger classes, and overall class size does not have to be a barrier to achieving high levels of MVPA.
SOLAR X-RAY FLARE DATA USING NEURAL NETWORK

In this study we develop a set of solar proton event (SPE) forecast models with NOAA scales by Multi Layer Perceptron (MLP), one of neural network methods, using GOES solar X-ray flare data from 1976 to 2011. Our MLP models are the first attempt to forecast the SPE scales by the neural network method. The combinations of X-ray flare class, impulsive time, and location are used for input data. For this study we make a number of trials by changing the number of layers and nodes as well as combinations of the input data. To find the best model, we use the summation of F-scores weighted by SPE scales, where F-score is the harmonic mean of PODy (recall) and precision (positive predictive value), in order to minimize both misses and false alarms. We find that the MLP models are much better than the multiple linear regression model and one layer MLP model gives the best result.
