In recent studies, miRNAs have been found to be extremely influential in many of the essential biological processes. They exhibit a self-regulatory mechanism through which they act as positive/negative regulators of expression of genes and other miRNAs. This has direct implications in the regulation of various pathophysiological conditions, signaling pathways and different types of cancers. Studying miRNA-disease associations has been an extensive area of research; however deciphering miRNA-miRNA network regulatory patterns in several diseases remains a challenge...

BACKGROUND: A detailed gait analysis (e.g., measures related to speed, self-affinity, stability, and variability) can help to unravel the underlying causes of gait dysfunction, and identify cognitive impairment. However, because geriatric patients present with multiple conditions that also affect gait, results from healthy old adults cannot easily be extrapolated to geriatric patients. Hence, we (1) quantified gait outcomes based on dynamical systems theory, and (2) determined their discriminative power in three groups: healthy old adults, geriatric patients with- and geriatric patients without cognitive impairment...

BACKGROUND: Previous evaluation showed insufficient use of a national guideline for integrated local health policy by Regional Health Services (RHS) in the Netherlands. The guideline focuses on five health topics and includes five checklists to support integrated municipal health policies. This study explores the determinants of guideline use by regional Dutch health professionals. METHODS: A web survey was send to 304 RHS health professionals. The questionnaire was based on a theory- and research-based framework of determinants of public health innovations...

AIMS: Using qualitative interviews, this study explored the experiences of GPs, vocational advisers and patients towards a new vocational advice (VA) service in primary care. METHODS: This study was nested within the Study of Work and Pain (SWAP) cluster randomised controlled trial. The SWAP trial located a VA service within three general practices in Staffordshire. Interviews took place with 10 GPs 12 months after the introduction of the VA service, four vocational advisers whilst the VA service was running and 20 patients on discharge from the VA service...

In chemical or physical reaction dynamics, it is essential to distinguish precisely between reactants and products for all times. This task is especially demanding in time-dependent or driven systems because therein the dividing surface (DS) between these states often exhibits a nontrivial time-dependence. The so-called transition state (TS) trajectory has been seen to define a DS which is free of recrossings in a large number of one-dimensional reactions across time-dependent barriers and thus, allows one to determine exact reaction rates...

Patient motivation is important in managing medication regimens such as antiretroviral treatment for HIV/AIDS. We tested whether self-determination theory could predict adherence behavior among 115 HIV-positive patients in the China Adherence through Technology Study, a randomized controlled trial of an intervention using text reminders and supportive counseling to increase adherence. Being in the treatment group had a significant effect on improving adherence; however, we did not find evidence that self-determination theory predicts adherence in this population of HIV-positive patients...

We employ a first-principles-based, force-level approach to construct the anharmonic tube confinement field for entangled fluids of rigid needles, and also for chains described at the primitive-path (PP) level in two limiting situations where chain stretch is assumed to either be completely equilibrated or unrelaxed. The influence of shear and extensional deformation and polymer orientation is determined in a nonlinear elastic limit where dissipative relaxation processes are intentionally neglected. For needles and PP-level chains, a self-consistent analysis of transverse polymer harmonic dynamical fluctuations predicts that deformation-induced orientation leads to tube weakening or widening...

Liquid water can persist in a supercooled state to below 238 K in the Earth's atmosphere, a temperature range where homogeneous nucleation becomes increasingly probable. However, the rate of homogeneous ice nucleation in supercooled water is poorly constrained, in part, because supercooled water eludes experimental scrutiny in the region of the homogeneous nucleation regime where it can exist only fleetingly. Here we present a new parameterization of the rate of homogeneous ice nucleation based on classical nucleation theory...

Women in recovery from addiction experience significant sociostructural barriers to reestablishing self, family, and home after having a baby. The aim of this grounded theory study was to describe pathways that women and their families followed and how transitions were experienced in the early years after receiving services through an integrated community-based maternity program. Eighteen women completed questionnaires and participated in a series of semistructured interviews over 2 years. The overall process women experienced was that of holding it together, which women did by restoring their sense of self during recovery, becoming a strong center for their family, and creating a sense of home no matter what the circumstances...

Piano lessons, weekly laboratory meetings, and visits to health care providers have in common an accountability that encourages people to follow a specified course of action. The accountability inherent in the social interaction between a patient and a health care provider affects patients' motivation to adhere to treatment. Nevertheless, accountability is a concept not found in adherence models, and is rarely employed in typical medical practice, where patients may be prescribed a treatment and not seen again until a return appointment 8-12 weeks later...

No research drawing from Self-Determination Theory has investigated the bereavement experience of individuals or how motivation can help facilitate posttraumatic growth (PTG) following the death of a loved one. In two cross-sectional studies, university students completed an online survey. Study 1 investigated the contribution of global autonomous and controlled motivation in statistically predicting PTG above and beyond previously researched correlates. Study 2 explored the mediating role of cognitive appraisals and coping in explaining the relationship between global motivation orientations and PTG...

INTRODUCTION: Children with cerebral palsy (CP) participate in leisure-time physical activities (PA) less often, with less intensity and reduced diversity than their typically developing peers. Participation in leisure-time physical activities may be an important source of habitual physical activity (HPA) for children with CP, who as a group have lower levels of HPA and increased sedentary time compared with their typically developing peers. The proposed study aims to compare the efficacy of a participation focused therapy (ParticiPAte CP) to usual care in a pragmatic, randomised waitlist controlled trial...

This study investigates the job demands-resources (JD-R) model in relation to work motivation in a self-determination theory (SDT) perspective, with the purpose of developing a model where social-contextual factors are seen in relation to psychological needs in order to explain autonomous work motivation and, in turn, self-reported work performance and somatic symptom burden. SEM-analyses of cross-sectional survey data including 405 waiters/waitresses in Norway were conducted to evaluate the hypothesized model...

INTRODUCTION: Interventions delivered in after-school programmes (ASPs) have the potential to become a means of ensuring adequate physical activity among schoolchildren. This requires a motivational climate, allowing for self-determined play. If trained, ASP staff may represent a valuable resource for supporting such play. Increasing knowledge and supportive skills among ASP staff may also potentially increase their motivation for work. The purpose of this article is to describe the development of the 'Active Play in ASP' intervention, which aims to promote physical activity among first graders attending ASP, and to present a protocol for a matched-pair cluster-randomised trial to evaluate the intervention...

Although prison life is generally characterized by little choice and autonomy, there exists considerable variation in the number and type of choices offered to different prisoners. Based on self-determination theory, which maintains that perceived afforded choice and autonomy are of crucial importance for individuals' psychological functioning, we investigated the relation between choice, autonomy satisfaction, and subjective quality of life among prisoners. We drew on quantitative cross-sectional data gathered among 156 Belgian prisoners (Mage = 38...

The Schrödinger theory for a system of electrons in the presence of both a static and time-dependent electromagnetic field is generalized so as to exhibit the intrinsic self-consistent nature of the corresponding Schrödinger equations. This is accomplished by proving that the Hamiltonian in the stationary-state and time-dependent cases {Ĥ;Ĥ(t)} are exactly known functionals of the corresponding wave functions {Ψ;Ψ(t)}, that is, Ĥ=Ĥ[Ψ] and Ĥ(t)=Ĥ[Ψ(t)]. Thus, the Schrödinger equations may be written as Ĥ[Ψ]Ψ=E[Ψ]Ψ and Ĥ[Ψ(t)]Ψ(t)=i∂Ψ(t)/∂t...

OBJECTIVE: Despite the benefits of physical activity, many cancer survivors do not adhere to clinically recommended levels. This qualitative study investigated factors of self-regulation contributing to survivor physical activity patterns. METHODS: Participants attended focus groups with prompts on exercise habits and self-regulation based on Social Cognitive Theory, Self-Determination Theory, and Self-Regulation Theory. Content analysis with a priori codes was conducted to identify emergent themes...

Joint refinement of X-ray and polarized neutron diffraction data has been carried out in order to determine charge and spin density distributions simultaneously in the nitronyl nitroxide (NN) free radical Nit(SMe)Ph. For comparison purposes, density functional theory (DFT) and complete active-space self-consistent field (CASSCF) theoretical calculations were also performed. Experimentally derived charge and spin densities show significant differences between the two NO groups of the NN function that are not observed from DFT theoretical calculations...

BACKGROUND: Guidelines recommend cardiac rehabilitation and long-term use of cardiac medications for most patients who have had a myocardial infarction (MI), but adherence to these secondary prevention treatments is suboptimal. METHODS: This is a multicenter, pragmatic, 3-arm randomized trial. Eligible patients (n = 2,742) with obstructive coronary artery disease are randomized post-MI to usual care or 1 of 2 intervention arms. Patients in the first intervention arm receive mail-outs sent on behalf of their cardiologist at 4, 8, 20, 32, and 44 weeks post-MI; content is designed to address determinants of adherence and facilitate discussion between the patient and their health care team...
