Abstract:

ABSTRACT The large virulence plasmid pMYSH6000 of Shigella flexneri contains a determinant that is highly effective in stabilizing otherwise unstable plasmids in Escherichia coli. Expression of two small contiguous genes, mvpAand mvpT (formerly termed STBORF1 and STBORF2), was shown to be sufficient for stability. Mutations in mvpT abolished plasmid stability, and plasmids expressing only mvpT killed the cells unless mvpA was supplied from a separate plasmid or from the host chromosome. When replication of a plasmid carrying the minimal mvp region was blocked, growth of the culture stopped aft

Abstract:

Children who encounter difficulties in the major childhood occupation of academic learning are often identified as having learning disabilities. The Motor-Free Test of Visual Perception Revised (MVPT-R) is a standardized assessment frequently used by occupational therapists to measure a child's visual perceptual skills that contribute to successful learning. Although the MVPT-R has been revised with additional normative data and test items, no validity studies using different populations have been reported. The present study investigated the ability of the MVPT-R to differentiate between child

Abstract:

Paediatric occupational therapists often assess and treat school-age children and youth presenting with visual perceptual dysfunction. It is, therefore, important that occupational therapists use visual perceptual instruments that possess sound measurement properties (such as validity, reliability, responsiveness and clinical utility). The Motor-Free Visual Perception Test – Revised (MVPT-R) is an instrument frequently used by paediatric occupational therapists. Clinicians need to be cognisant of the measurement properties of the assessments they use in order to provide the best level of care

Abstract:

Patients who have hemispatial visual neglect (HVN) have difficulty directing their attention toward the visual field contralateral to the side of the lesion. This affects their performance on perceptual assessment tests and masks related visual perceptual deficits. The aim of this study was to verify whether a vertical position of the answer cards of the Motor Free Visual Perceptual Test (MVPT) could overcome this problem. Three groups of subjects were involved in the study: 15 healthy subjects, 15 subjects who had right brain damage without HVN, and 9 subjects who had right brain damage with

Abstract:

Mouse polyomavirus has been used as a model system to study nucleocytoplasmic transport of mRNA. Three late mRNAs encoding the viral capsid proteins are generated by alternative splicing from common pre-mRNA molecules. mRNAs encoding the virion protein VP2 (mVP2) harbor an unused 5' splice site, and more than half of them remain fully unspliced yet are able to enter the cytoplasm for translation. Examination of the intracellular distribution of late viral mRNAs revealed, however, that mVP2 molecules are exported less efficiently than are mVP1 and mVP3, in which the 5' splice site has been remo

Abstract:

Background: Surveillance of domain-specific physical activity in the United States is lacking. Thus, the authors describe domain-specific moderate to vigorous physical activity (MVPA) in a nationwide sample of US adults. Methods: Participants from the AmeriSpeak panel (n = 2649; 20–75 y; 50% female) completed the Activities Completed Over Time in 24-Hours previous-day recall. The authors estimated average MVPA duration (in hours per day) overall and in major life domains by sex, age, race/ethnicity, and education. They also described the most commonly reported MVPAs and timing of MVPA during t

Abstract:

This investigation examined parental influence on children’s moderate to vigorous physical activity (MVPA) participation via an expectancy-value model that included parents’ behavior, parents’ beliefs about their children’s MVPA, and children’s beliefs about their MVPA. The influence of parents on their children’s MVPA was investigated via questionnaires tapping the belief systems of fourth- and fifth-grade children (n=71) and their parents (n=69). Self-reported MVPA was assessed for parents and children. Correlational analyses demonstrated a number of significant relationships between parents

Abstract:

Background:Objective physical activity data analyses focus on moderate-to-vigorous physical activity (MVPA) without considering lower intensity lifestyle-type activities (LA). We describe 1) quantity of LA (minutes and steps per day) across demographic groups, 2) proportion of LA to total physical activity, and 3) relationships between LA and MVPA using NHANES 2005−2006 accelerometer adult data (n = 3744).Methods:LA was defined as 760 to 2019 counts per minute (cpm) and MVPA as ≥2020 cpm. LA was compared within gender, ethnicity, age, and BMI groups. Regression analyses examined independent ef

Abstract:

Background: Interventions to raise population physical activity generally show modest effects; one possible reason is that trends and determinants of moderate to vigorous physical activity (MVPA) differ between population subgroups. This study examined differences in trends and determinants of reported MVPA by ethnicity/race and sex in a 15-year longitudinal study. Methods: Participants (n = 2092) in the Project Eating and Activity in Teens and Young Adults study were surveyed on MVPA behavior and potential determinants from adolescence to young adulthood.

Abstract:

This study aimed to examine the association among parental moderate-to-vigorous physical activity (MVPA), parental support, and the MVPA of children by gender. Participants comprised of 172 boys and 151 girls aged seven to 11 years old from three primary schools in Shanghai. Their parents were also included as research respondents. Accelerometers were utilized to measure MVPA duration among the children. Questionnaires that focused on parental support and MVPA were completed by the parents. Results indicated that only 4% of the children met the recommended MVPA duration of 60 minutes per day b

Abstract:

The health benefits of physical activity (PA) are well known. However, the association between an adequate amount of moderate–vigorous PA (MVPA) and clinical outcomes has limited evidence in chronic kidney disease (CKD). We assessed PA using a self-administered questionnaire. The amount of MVPA was categorized into four groups: none, low, moderate, and high (0, <7.5, 7.5–14.9, and 15.0–29.9 metabolic equivalent-hours/week, respectively). We analyzed the association between the amount of MVPA and clinical outcomes. Among a total of 1909 adults with CKD, adults with MVPA showed various benefi

Abstract:

Background:Pedometer step-frequency thresholds (120 steps·min-1, SPM) corresponding to moderate-to-vigorous intensity physical activity (MVPA) have been proposed for youth. Pedometers now have internal mechanisms to record time spent at or above a user-specified SPM. If pedometers provide comparable MVPA (P-MVPA) estimates to those from accelerometry, this would have broad application for research and the general public. The purpose of this study was to examine the convergent validity of P-MVPA to accelerometer-MVPA for youth.Methods:Youth (N = 149, average 8.6 years, range 5 to 14 years, 60 g

Abstract:

Background.Physical activity guidelines for adults only recognize the health benefits of accumulating bouted moderate-to-vigorous physical activity (MVPA), or MVPA occurring over at least 10 consecutive minutes. There is a lack of evidence supporting the health benefits of other patterns and intensities of activity including sporadic MVPA (i.e., MVPA occurring in periods of fewer than 10 consecutive minutes) and light intensity physical activity (LIPA). The objective of this study was to examine the health benefits associated with physical activity that does not meet the physical activity guid

Abstract:

The major vault protein (MVP) is the predominant constituent of ubiquitous, evolutionarily conserved large cytoplasmic ribonucleoprotein particles of unknown function. Vaults are multimeric protein complexes with several copies of an untranslated RNA. Double labeling employing laser-assisted confocal microscopy and indirect immunofluorescence demonstrates partial colocalization of vaults with cytoskeletal elements in Chinese hamster ovary (CHO) and nerve growth factor (NGF)-treated neuronlike PC12 cells. Transfection of CHO and PC12 cells with a cDNA encoding the rat major vault protein contai
