Inferring the rates of change of a population from a reconstructed phylogeny of genetic sequences is a central problem in macro-evolutionary biology, epidemiology, and many other disciplines. A popular solution involves estimating the parameters of a birth-death process (BDP), which links the shape of the phylogeny to its birth and death rates. Modern BDP estimators rely on random Markov chain Monte Carlo (MCMC) sampling to infer these rates. Such methods, while powerful and scalable, cannot be guaranteed to converge, leading to results that may be hard to replicate or difficult to validate. We present a conceptually and computationally different parametric BDP inference approach using flexible and easy to implement Snyder filter (SF) algorithms. This method is deterministic so its results are provable, guaranteed, and reproducible. We validate the SF on constant rate BDPs and find that it solves BDP likelihoods known to produce robust estimates. We then examine more complex BDPs with time-varying rates. Our estimates compare well with a recently developed parametric MCMC inference method. Lastly, we performmodel selection on an empirical Agamid species phylogeny, obtaining results consistent with the literature. The SF makes no approximations, beyond those required for parameter quantisation and numerical integration, and directly computes the posterior distribution of model parameters. It is a promising alternative inference algorithm that may serve either as a standalone Bayesian estimator or as a useful diagnostic reference for validating more involved MCMC strategies. The Snyder filter is implemented in Matlab and the time-varying BDP models are simulated in R.

Oligomeric organophosphate esters (OOPEs) like 2,2-bis(chloromethyl)-propane-1,3-diyltetrakis (2-chloroethyl) bisphosphate (V6), resorcinol bis(diphenylphosphate) (RDP) and bisphenol A bis(diphenylphosphate) (BDP), are widely used as alternatives of Deca-BDE in plastic and electronic consumer products. However, studies on the environmental occurrence and fate of OOPEs are very scarce. This work studied the occurrence, distribution and fate of V6, BDP and RDP during the different treatment stages of a sewage treatment plant (STP) in Beijing, China. To accomplish this, a method to analyze trace V6, BDP and RDP in suspended solids samples and aqueous samples of sewage and sludge was developed by using liquid chromatography tandem mass spectrometry (LC-MS/MS). Using this method, BDP and RDP were detected for the first time in suspended solids of sewage and sludge with a concentration of 2.06-5.82 ng/g dry weight and 0.44-3.45 ng/g dry weight, respectively, whereas their concentration level in the aqueous phase of these samples were below the detection limits of the method. However, V6 was detected in all treatment stages of the STP, with concentrations in the range of 10.2-27.1 ng/L in aqueous phase and 0.40-1.73 ng/g dw in solid phase. Mass balance results indicated that 75.6% of the original V6 mass flow was discharged along with effluent, while 83.3% and 72.2% of the initial RDP and BDP mass flow were lost due to biodegradation, respectively. Nevertheless, compared to the 14 widely used monomeric organophosphate esters (MOPEs), the concentration levels of OOPEs in this studied STP were relatively low. Copyright © 2017 Elsevier Ltd.

An efficient functional mimic of the photosynthetic antenna-reaction center has been designed and synthesized. The model contains a near-infrared-absorbing aza-boron-dipyrromethene (ADP) that is connected to a monostyryl boron-dipyrromethene (BDP) by a click reaction and to a fullerene (C60 ) using the Prato reaction. The intramolecular photoinduced energy and electron-transfer processes of this triad as well as the corresponding dyads BDP-ADP and ADP-C60 have been studied with steady-state and time-resolved absorption and fluorescence spectroscopic methods in benzonitrile. Upon excitation, the BDP moiety of the triad is significantly quenched due to energy transfer to the ADP core, which subsequently transfers an electron to the fullerene unit. Cyclic and differential pulse voltammetric studies have revealed the redox states of the components, which allow estimation of the energies of the charge-separated states. Such calculations show that electron transfer from the singlet excited ADP ((1) ADP*) to C60 yielding ADP(.+) -C60 (.-) is energetically favorable. By using femtosecond laser flash photolysis, concrete evidence has been obtained for the occurrence of energy transfer from (1) BDP* to ADP in the dyad BDP-ADP and electron transfer from (1) ADP* to C60 in the dyad ADP-C60 . Sequential energy and electron transfer have also been clearly observed in the triad BDP-ADP-C60 . By monitoring the rise of ADP emission, it has been found that the rate of energy transfer is fast (≈10(11)  s(-1) ). The dynamics of electron transfer through (1) ADP* has also been studied by monitoring the formation of C60 radical anion at 1000 nm. A fast charge-separation process from (1) ADP* to C60 has been detected, which gives the relatively long-lived BDP-ADP(.+) C60 (.-) with a lifetime of 1.47 ns. As shown by nanosecond transient absorption measurements, the charge-separated state decays slowly to populate mainly the triplet state of ADP before returning to the ground state. These findings show that the dyads BDP-ADP and ADP-C60 , and the triad BDP-ADP-C60 are interesting artificial analogues that can mimic the antenna and reaction center of the natural photosynthetic systems.

The myotonic dystrophy-related Cdc42-binding kinases MRCKα and MRCKβ contribute to the regulation of actin-myosin cytoskeleton organization and dynamics, acting in concert with the Rho-associated coiled-coil kinases ROCK1 and ROCK2. The absence of highly potent and selective MRCK inhibitors has resulted in relatively little knowledge of the potential roles of these kinases in cancer. Here, we report the discovery of the azaindole compounds BDP8900 and BDP9066 as potent and selective MRCK inhibitors that reduce substrate phosphorylation, leading to morphologic changes in cancer cells along with inhibition of their motility and invasive character. In over 750 human cancer cell lines tested, BDP8900 and BDP9066 displayed consistent antiproliferative effects with greatest activity in hematologic cancer cells. Mass spectrometry identified MRCKα S1003 as an autophosphorylation site, enabling development of a phosphorylation-sensitive antibody tool to report on MRCKα status in tumor specimens. In a two-stage chemical carcinogenesis model of murine squamous cell carcinoma, topical treatments reduced MRCKα S1003 autophosphorylation and skin papilloma outgrowth. In parallel work, we validated a phospho-selective antibody with the capability to monitor drug pharmacodynamics. Taken together, our findings establish an important oncogenic role for MRCK in cancer, and they offer an initial preclinical proof of concept for MRCK inhibition as a valid therapeutic strategy. Significance: The development of selective small-molecule inhibitors of the Cdc42-binding MRCK kinases reveals their essential roles in cancer cell viability, migration, and invasive character.

The kinetics, dosimetry, and response of iodine-131 alpha-amino-(4-hydroxybenzylidene)-diphosphonate ([131I]BDP3) treatment were investigated with patients who had pain symptoms from bone metastases of various primary carcinoma. The blood clearance of [131I]BDP3 was rapid. More than 90% disappeared from the blood pool at 2 hr after injection. The excretion of the activity occurred solely through the kidneys and mean total-body retention at 48 hr was 48.6%. The urinary activity showed a metabolite which must be formed by an in vivo cleavage reaction of a phosphorus-carbon bond. The uptake of in vivo cleaved [131I]iodide in the unblocked thyroid was approximately 0.5%. The effective half-life of [131I]BDP3 in metastatic bone (median 182 hr; range 177-205 hr) proved to be longer than in unaffected areas (145 hr; 140-165 hr). Palliative therapies were performed with 18 patients. They received doses ranging between 6 and 48 mCi [131I]BDP3. The response was 44% complete pain relief, 6% substantial pain relief, 22% minimal improvement, and 28% no change. The duration of response ranged between 1 and 8 wk.

Asthma is a chronic disease characterized by acute symptomatic episodes with variable severity and duration. Pharmacological asthma management aims to achieve and maintain control without side effects, thus improving quality of life and reducing the economic impact. Recently, a clinical trial showed the non-inferiority of beclomethasone/formoterol (BDP/F) versus fluticasone propionate/salmeterol (FP/S) in adults with moderate to severe persistent asthma. However, this study did not provide evidence on costs and did not quantify quality-of-life parameters. The objective of the present study was to assess the cost effectiveness and cost utility of BDP/F versus FP/S in patients with moderate to severe asthma from the perspective of the Italian National Health Service (NHS). A Markov model (MM) was used, with five health states for the different levels of asthma control: successful control, sub-optimal control, outpatient-managed exacerbation, inpatient-managed exacerbation, and death. Model data were derived from the ICAT SE study and from expert panels. Three outcomes were considered: time spent in successful control state, costs and quality-adjusted life-years (QALYs). The model shows that BDP/F treatment led to a slight increase of weeks in successful control compared with FP/S, with a lower cost. The probabilistic sensitivity analysis highlights that in 64% and 68% of the Monte Carlo simulations, BDP/F outperformed FP/S in terms of weeks in successful control and QALYs. Considering the expected cost of the two strategies, in 90% of simulations BDP/F was the least expensive choice. In particular, BDP/F was cost saving as compared with FP/S in about 63% and 59% of simulations as shown by the cost-utility and cost-effectiveness analysis, respectively. Overall, from the Italian NHS perspective, BDP/F treatment is associated with a reduction in cost and offers a slight increase of effectiveness in terms of weeks spent in successful control and QALYs. © 2012 Adis Data Information BV.

The choice among the different treatments available can have a great impact on the costs of asthma, The objective of this study was to estimate the incremental cost-utility ratio of three inhaled corticosteroids (ICs): budesonide (BUD), fluticasone propionate (FP), and ciclesonide, compared to beclomethasone dipropionate (BDP) (the only IC included in the Compulsory Health Insurance Plan of Colombia), A Markov-type model was developed to estimate costs and health outcomes of a simulated cohort of patients less than 18 years of age with persistent asthma treated over a 12-month period. Effectiveness parameters were obtained from a systematic review of the literature. Cost data were obtained from a hospital´s bills and from the national manual of drug prices. The study assumed the perspective of the national healthcare in Colombia. The main outcome was the variable "quality-adjusted life years" (QALY), RESULTS: While treatment with BDP was associated with the lowest cost (£106.16 average cost per patient during 12 months), treatment with FP resulted in the greatest gain in QUALYs (0.9325 QALYs). FP was associated with a greater gain in QALYs compared to BUD and ciclesonide (0.9325 vs. 0.8999 and 0.9051 QALYs, respectively) at lower costs (£231.19 vs. £309.27 and £270.15, respectively), thus leading to dominance. The incremental cost-utility ratio of FP compared to BDP was £19,835.28 per QALY, CONCLUSIONS: BDP is the most cost-effective therapy for treating pediatric patients with persistent asthma when willingness to pay (WTP) is less than £21,129.22/QALY, otherwise, FP is the most cost-effective therapy.

Although cognitive deficits are consistent endophenotypes of schizophrenia and bipolar disorder, findings in psychotic bipolar disorder (BDP) are inconsistent. In this study we compared adult unaffected first-degree relatives of schizophrenia and BDP patients on cognition, psychopathology, social functioning and quality of life. Sixty-six unaffected first-degree relatives of schizophrenia patients (SUnR), 36 unaffected first-degree relatives of BDP patients (BDPUnR) and 102 controls participated in the study. Between-group differences were examined and Discriminant Function Analysis (DFA) predicted group membership. Visual memory, control inhibition, working memory, cognitive flexibility and abstract reasoning were linearly impaired in the relatives' groups. Poorer verbal fluency and processing speed were evident only in the SUnR group. The SUnR group had higher depressive and somatization symptoms while the BDPUnR group had higher anxiety and lower social functioning compared with the controls. Individuals with superior cognition were more likely to be classified as controls; those with higher social functioning, prolonged processing speed and lower anxiety were more likely to be classified as SUnR. The relatives' sample is quite heterogeneous; the effects of genetic or environmental risk-factors were not examined. Cognitive functions mediated by a fronto-parietal network, show linear impairments in unaffected relatives of BDP and schizophrenia patients; processing speed and verbal fluency impairments were evident only in schizophrenia relatives. Self-perceived symptomatology and social functioning also differ between schizophrenia and BDP relatives. The continuum seen in patients in several indices was also seen in the cognitive impairments in unaffected relatives of schizophrenia and BDP patients. Copyright © 2016 Elsevier B.V.

Disrupted sensory processing is a core feature of psychotic disorders. Auditory paired stimuli (PS) evoke a complex neural response, but it is uncertain which aspects reflect shared and/or distinct liability for the most common severe psychoses, schizophrenia (SZ) and psychotic bipolar disorder (BDP). Evoked time-voltage/time-frequency domain responses quantified with EEG during a typical PS paradigm (S1-S2) were compared among proband groups (SZ [n = 232], BDP [181]), their relatives (SZrel [259], BDPrel [220]), and healthy participants (H [228]). Early S1-evoked responses were reduced in SZ and BDP, while later/S2 abnormalities showed SZ/SZrel and BDP/BDPrel specificity. Relatives' effects were absent/small despite significant familiality of the entire auditorineural response. This pattern suggests general and divergent biological pathways associated with psychosis, yet may reflect complications with conditioning solely on clinical phenomenology.

Ulcerative colitis (UC) is a chronic and remitting inflammatory disease that is characterized by chronic idiopathic inflammation of the colon and bloody diarrhea. Currently drug treatment is the main intervention for patients with mild to moderate UC. Mesalazine (5-ASA) and beclomethasone dipropionate (BDP) have been widely used for the treatment of UC and have yielded satisfactory results. This study compared the effectiveness of 5-ASA and BDP in the treatment of UC. The PubMed, Medline, SinoMed, Embase, and Cochrane Librinary databases were searched for eligible studies. Data were extracted by two of the coauthors independently and were analyzed using RevMan statistical software, version 5.3. Weighted mean differences (WMDs), odds ratios (ORs), and 95% confidence intervals (CIs) were calculated. Cochrane Collaboration's Risk of Bias Tool was used to assess the risk of bias. Seven randomized controlled trials that compared BDP with 5-ASA in treating UC were identified as eligible. The methodological quality of the trials ranged from low to moderate. A pooled analysis of effectiveness based on the Disease Activity Index (DAI) or other assessment method after treatment revealed that in the treatment of UC, there are no obvious differences between BDP and 5-ASA in inducing remission and clinical improvement (OR = 0.76, 95% CI = 0.56-1.03, P = 0.08). The total numbers of adverse events associated with BDP and 5-ASA treatments for UC were similar (OR = 1.21, 95% CI = 0.71-2.09, P = 0.48). The safety profiles for these two drugs are good. According to subgroup-analysis, we found no obvious differences of clinical efficacy between BDP and 5-ASA no matter oral or enema administration was used in the treatment of UC. A sensitivity analysis demonstrated the stability of the pooled results. During induction treatment of mild to moderate UC, there is no obvious difference between the two groups with respect to remission and clinical improvement. Given that the upper confidence limit for the OR barely exceeds 1.0 and that the p-value is close to 0.05 for this primary efficacy outcome as well as that the horizontal block lies to the left of the vertical line, it indicates that the clinical efficacy of BDP may be better than 5-ASA. However, taking into account that BDP has the risk of hypothalamic-pituitary-adrenal axis (HPA) suppression, 5-ASA has a potential advantage of safety in the treatment of mild to moderate UC.

With a 4-aminostyryl group introduced at its 3-position, a BODIPY BDP-ODTAC was derived as a new ratiometric sensor for Ag + by modifying 4-amino group as a Ag + chelator, 1-oxa-4,10-dithia-7-azacyclododecane (ODTAC). In addition to the specific Ag + -induced hypsochromic absorption shift from 606 to 562 nm, this sensor demonstrated an excitation shift from 600 to 560 nm due to the internal charge transfer (ICT) effect endowed by the introduced α-4-aminostyryl group. The Ag + -induced recovery and enhancement of the intrinsic local emission band was also observed. The different sensing behavior of ODTAC-BDP with chelator ODTAC substituting on the meso-phenyl group infers that the ratiometric sensing behavior of BDP-ODTAC is correlated to the amino group in ODTAC acting as the electron donor for the ICT effect. With high Ag + selectivity over interfering cations such as Hg 2+ and Pb 2+ , BDP-ODTAC displays a fluorometric limit of detection (LOD) of ∼17 nM (∼0.002 ppm), which is distinctly lower than EPA and WHO standards for drinking water (500 nM, ∼0.055 ppm). Moreover, the BDP-ODTAC-doped PVC film shows the Ag + sensitivity of 1 ppm with a color switch from blue to purple, providing this sensor the ability to determine Ag + in totally aqueous solution sensitively via naked-eye detection.

Inhaled corticosteroids have the potential to produce upper-airway side effects such as hoarseness. As new compounds and delivery devices are developed and compared, it is difficult to quantify their adverse upper-airway effects. We undertook the following study to test the ability of an acoustic analysis technique to quantify changes in vocal function in steroid-naive patients with asthma who receive inhaled beclomethasone dipropionate (BDP), 1,000 microg/d for 4 months. Patients self-administered one of four regimens of inhaled BDP. Group 1 patients received one 250-microg puff qid via metered-dose inhaler (MDI); group 2 patients received one 250-microg puff qid via MDI with a holding chamber; group 3 patients received two 250-microg puffs bid via MDI; and group 4 patients received two 250-microg puffs bid via MDI with a holding chamber. A smaller cohort of nonsmoking asthmatic patients was managed without steroid intervention for 4 months. At baseline and again at 8 weeks and 16 weeks after the initiation of BDP treatment, patients underwent spirometry and methacholine challenge. At baseline and again at 2, 4, 8, 12, and 16 weeks, patients underwent voice recording for analysis of voice parameters. The recorded vowels were low-pass filtered (10 KHz), digitized (22 KHz), and analyzed by software to obtain two acoustic measures: (1) jitter, the cycle-to-cycle variation in the time period of the voice signal; and (2) shimmer, the cycle-to-cycle variation in voice signal amplitude. We recruited 77 patients for randomization to inhaled steroid therapy and 10 patients who continued to receive only occasional inhaled bronchodilator therapy. In all active treatment groups, FEV(1), FVC, and provocative concentration of methacholine causing a 20% fall in FEV(1) improved significantly after BDP treatment. Mean jitter scores, a measurement of variation in voice pitch, were not significantly influenced by BDP treatment. However, mean shimmer scores, a reflection of perturbation in vocal amplitude, fell significantly (p < 0.05) in the active treatment groups. These reductions in shimmer scores were not significantly different in the active treatment groups. Shimmer scores in the bronchodilator-treated group were unchanged during the 16 weeks of follow-up. Our data show that a simple and noninvasive acoustic analysis of voice is sensitive to subclinical changes associated with inhaled corticosteroid therapy. We have shown that 1,000 microg/d of inhaled BDP actually improves specific acoustic measures of voice in patients with inadequately controlled asthma. These improvements were uninfluenced by dosing schedule and whether a spacing chamber was used.

Tissue penetration depth is a major challenge in practical photodynamic therapy (PDT). A biocompatible and highly effective near infrared (NIR)-light-absorbing carbazole-substituted BODIPY (Car-BDP) molecule is reported as a class of imaging-guidable deep-tissue activatable photosensitizers for PDT. Car-BDP possesses an intense, broad NIR absorption band (600-800 nm) with a remarkably high singlet oxygen quantum yield (Φ Δ = 67%). After being encapsulated with biodegradable PLA-PEG-FA polymers, Car-BDP can form uniform and small organic nanoparticles that are water-soluble and tumor-targetable. Rather than using laser light, such nanoparticles offer an unprecedented deep-tissue, tumor targeting photodynamic therapeutic effect by using an exceptionally low-power-density and cost-effective lamp light (12 mW cm -2 ). In addition, these nanoparticles can be simultaneously traced in vivo due to their excellent NIR fluorescence. This study signals a major step forward in photodynamic therapy by developing a new class of NIR-absorbing biocompatible organic nanoparticles for effective targeting and treatment of deep-tissue tumors. This work also provides a potential new platform for precise tumor-targeting theranostics and novel opportunities for future affordable clinical cancer treatment.

Conductive metal-organic frameworks are an emerging class of three-dimensional architectures with degrees of modularity, synthetic flexibility and structural predictability that are unprecedented in other porous materials. However, engendering long-range charge delocalization and establishing synthetic strategies that are broadly applicable to the diverse range of structures encountered for this class of materials remain challenging. Here, we report the synthesis of K x Fe 2 (BDP) 3 (0 ≤ x ≤ 2; BDP 2-  = 1,4-benzenedipyrazolate), which exhibits full charge delocalization within the parent framework and charge mobilities comparable to technologically relevant polymers and ceramics. Through a battery of spectroscopic methods, computational techniques and single-microcrystal field-effect transistor measurements, we demonstrate that fractional reduction of Fe 2 (BDP) 3 results in a metal-organic framework that displays a nearly 10,000-fold enhancement in conductivity along a single crystallographic axis. The attainment of such properties in a K x Fe 2 (BDP) 3 field-effect transistor represents the realization of a general synthetic strategy for the creation of new porous conductor-based devices.

The toxic effect of aflatoxins (AF) and zearalenone (ZEA) and their combination on laying performance, egg quality and toxins residues in eggs, as well as the efficacy of Bacillus subtilis biodegradation product (BDP) for ameliorating these effects in layers were evaluated. Layers were submitted to a two phase experiment. The first phase was an intoxication period (18-23 wk) with birds fed 7 (3 × 2 + 1) diets (3 treatments with mycotoxins: AF (123.0 μg/kg), ZEA (260.2 μg/kg), or AF + ZEA (123.0 + 260.2 μg/kg); 2 treatments with or without BDP (1000 g/t); and a control group contained no toxins nor BDP). The next phase was a recovery period (24-29 wk) in which birds were fed a toxin-free diet. In the intoxication period, AF and AF + ZEA groups exhibited lower egg production, feed intake and shell thickness, and higher AFB1, AFB2 and AFM1 residues as compared with the control group. In addition, AF and ZEA exerted synergistic effects on egg production and feed intake. Moreover, AF alone or combined with ZEA had a continuous toxic effect on laying performance in the recovery phase. Addition of BDP offset these negative effects, showing that BDP has a protective effect on layers fed contaminated diets. Copyright © 2016 Elsevier Ltd. All rights reserved.

Viscosity, as one of the major factors of intracellular microenvironment, influences the function of proteins. To detect local micro-viscosity of a protein, it is a precondition to apply a viscosity sensor for specifically target to proteins. However, all the reported small-molecule probes are just suitable for sensing/imaging of macro-viscosity in biological fluids of entire cells or organelles. To this end, we developed a hybrid sensor BDP-V BG by connecting a viscosity-sensitive boron-dipyrromethene (BODIPY) molecular rotor (BDP-V) to O 6 -benzylguanine (BG) for specific detection of local micro-viscosity of SNAP-tag fused proteins. We measured and calculated the reaction efficiency between the sensor and SNAP-tag protein in vitro to confirm the high labeling specificity. We also found that the labeling reaction results in a 53-fold fluorescence enhancement for the rotor, which qualifies it as a wash-free sensor with ignorable background fluorescence. The high sensitivity of protein labeled sensor (BDP-V-SNAP) to the changes of local viscosity was evaluated by detecting the enhancement of fluorescence lifetimes. Further, with the sensor BDP-V BG, we achieved high specific labeling of cells expressing two SNAP-tag fused proteins (nuclear histone H2B and mitochondrial COX8A). Two-photon excited fluorescence lifetime imaging revealed that, the micro-viscosities nearby the SNAP-tag fused two proteins are distinct. The different changes of local micro-viscosity of SNAP-tag fused histone protein in apoptosis induced by three nucleus-targeted drugs were also characterized for the first time.

A metal organic framework Fe.sub.2(bdp).sub.3 (BDP.sup.2-=1,4-benzenedipyrazolate) with triangular channels is particularly suited for C5-C7 separations of alkanes according to the number of branches in the molecule rather than by carbon number. The metal-organic framework can offer pore geometries that is unavailable in zeolites or other porous media, facilitating distinct types of shape-based molecular separations.

This study sought to examine whole brain and regional gray matter (GM) phenotypes across the schizophrenia (SZ)–bipolar disorder psychosis dimension using voxel-based morphometry (VBM 8.0 with DARTEL segmentation/normalization) and semi-automated regional parcellation, FreeSurfer (FS 4.3.1/64 bit). 3T T1 MPRAGE images were acquired from 19 volunteers with schizophrenia (SZ), 16 with schizoaffective disorder (SAD), 17 with psychotic bipolar I disorder (BD-P) and 10 healthy controls (HC). Contrasted with HC, SZ showed extensive cortical GM reductions, most pronounced in fronto-temporal regions; SAD had GM reductions overlapping with SZ, albeit less extensive; and BD-P demonstrated no GM differences from HC. Within the psychosis dimension, BD-P showed larger volumes in fronto-temporal and other cortical/subcortical regions compared with SZ, whereas SAD showed intermediate GM volumes. The two volumetric methodologies, VBM and FS, revealed highly overlapping results for cortical GM, but partially divergent results for subcortical volumes (basal ganglia, amygdala). Overall, these findings suggest that individuals across the psychosis dimension show both overlapping and unique GM phenotypes: decreased GM, predominantly in fronto-temporal regions, is characteristic of SZ but not of psychotic BD-P, whereas SAD display GM deficits overlapping with SZ, albeit less extensive.

By three-dimensional (3D) finite element method (FEM) plasmon mapping, gradual plasmon evolutions of both bonding dipole plasmon (BDP) and charge transfer plasmon (CTP) modes are visualized. In particular, the evolved BDP mode provides a physical insight into the rapid degeneration of electromagnetic hot spots in practical applications, while the rising CTP mode enables a huge near-field enhancement for potential plasmonic devices at infrared wavelengths.

Effect of interstitial palladium on plasmon-driven charge transfer in nanoparticle dimers.

PubMed

Lerch, Sarah; Reinhard, Björn M

2018-04-23

Capacitive plasmon coupling between noble metal nanoparticles (NPs) is characterized by an increasing red-shift of the bonding dipolar plasmon mode (BDP) in the classical electromagnetic coupling regime. This model breaks down at short separations where plasmon-driven charge transfer induces a gap current between the NPs with a magnitude and separation dependence that can be modulated if molecules are present in the gap. Here, we use gap contained DNA as a scaffold for the growth of palladium (Pd) NPs in the gap between two gold NPs and investigate the effect of increasing Pd NP concentration on the BDP mode. Consistent with enhanced plasmon-driven charge transfer, the integration of discrete Pd NPs depolarizes the capacitive BDP mode over longer interparticle separations than is possible in only DNA-linked Au NPs. High Pd NP densities in the gap increases the gap conductance and induces the transition from capacitive to conductive coupling.

The effect of intranasal corticosteroids and oral antihistamines on acoustic rhinometry parameters was not directly compared in previous studies. Objectives: The primary aim was to compare the effect of 21-day treatment with nasal beclomethasone dipropionate (nBDP) versus cetirizine (CTZ) on nasal patency measured by acoustic rhinometry in children with PAR. Comparing their effect on nasal cytology, symptom severity, sleep quality and quality of life was the secondary aim. In this 21-day, open-label, randomized controlled study, 34 PAR children (6-14 years) with Total 5 Symptom Score (T5SS) ≥5 received nBDP 100 µg per nostril twice daily or CTZ 10 mg tablets once daily. Effect measures were the least square mean changes (LSmc) in nasal volume and Minimal Cross-sectional Area (MCA), nasal cytology, T5SS, Pittsburgh Sleep Quality Index (PSQI) and Paediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ). After 21 days, nBDP improved nasal volume and MCA more than CTZ (LSmc 2.21 cm3 vs 0.20 cm3, p=0.013 and LSmc 0.63 cm2 vs 0.13 cm2, p=0.002, respectively). In the nBDP group, with respect to the CTZ group, larger improvement was found in: eosinophil (LSmc -1.10 vs -0.40, p=0.031) and neutrophil (LSmc -0.97 vs -0.17, p=0.010) classes, T5SS (LSmc -5.63 vs -3.54, p=0.008), PSQI (LSmc -1.30 vs -0.19, p=0.025) and PRQLQ total scores (LSmc -1.15 vs -0.69, p=0.031). In children with PAR, nBDP is more effective than CTZ in improving nasal patency measured by acoustic rhinometry, with associated beneficial effects on nasal cytology, symptoms, sleep quality and quality of life.

Polarization optics of the Brewster's dark patch visible on water surfaces versus solar height and sky conditions: theory, computer modeling, photography, and painting.

When the sun is near the horizon, a circular band with approximately vertically polarized skylight is formed at 90° from the sun, and this skylight is only weakly reflected from the region of the water surface around the Brewster's angle (53° from the nadir). Thus, at low solar heights under a clear sky, an extended dark patch is visible on the water surface when one looks toward the north or south quarter perpendicular to the solar vertical. In this work, we study the radiance distribution of this so-called Brewster's dark patch (BDP) in still water as functions of the solar height and sky conditions. We calculate the pattern of reflectivity R of a water surface for a clear sky and obtain from this idealized situation the shape of the BDP. From three full-sky polarimetric pictures taken about a clear, a partly cloudy, and an overcast sky, we determine the R pattern and compose from that synthetic color pictures showing how the radiance distribution of skylight reflected at the water surface and the BDPs would look under these sky conditions. We also present photographs taken without a linearly polarizing filter about the BDP. Finally, we show a 19th century painting on which a river is seen with a dark region of the water surface, which can be interpreted as an artistic illustration of the BDP.

Arsenic in groundwaters of rural India: its geochemistry and mitigation approaches

During the last few decades, arsenic (As) has been recognized as the most threatening contaminant in natural waters (especially groundwater). It has become a menace to the health of millions of people worldwide. Many large and small communities experience As contamination in groundwater and/or drinking water supplies in south-east Asia and the problem is grave in West Bengal and Bangladesh (Bengal Delta Plain, BDP) both in terms of human exposure as well as spatial coverage. It is frequently observed that As concentration in contaminated wells exceeds both WHO guideline value (10 mg/l) and stipulated National standard (50 mg/l) for both Bangladesh and India. Dissolved forms of As in the BDP water include arsenite (~50-70%), arsenate (~30-50%) and ultra-trace amount of monomethylarsonic acid and dimethylarsinic acid. Arsenite and arsenate species can interchange depending on redox potential (Eh), pH and biological processes. The prevailing local geomorphological features (surface water, sanitation, agricultural activity) can also influence the mobilization of As in addition to the dominant geological factors. Therefore, the local sedimentology and hydrogeology should also be given importance prior to implement or consider any policy to mitigate the As contamination of groundwater. Conventional treatment techniques to remove As from groundwater are costly and difficult to practice in rural areas of the BDP. There are several techniques available for groundwater As removal. Iron and Alum coagulation, softening [mediated by calcite or Mg(OH)2 formation], by reverse osmosis, using zero-valent iron and nanoparticulate zero-valent iron, several natural/synthetic metal oxides, naturally found minerals like siderite, hematite, using iron doped activated carbons, development of bio-physicochemical techniques, using granular TiO2 adsorbent are some of the many proposed removal techniques investigated by various researchers. Instead of using hazardous chemicals (e.g. chlorine, ozone in conventional method) As from groundwater can also be removed by exposure to sunlight (solar oxidation) in presence of dissolved iron (Fe) and a chelating agent (citrate, naturally available) followed by filtration with cloth or simple decantation. The technique is user friendly, low cost and easy to perform by the rural mass of the BDP.

To investigate the influence of different actuator materials and nozzle designs on the electrostatic charge properties of a series of solution metered dose inhaler (pMDI) aerosols. Actuators were manufactured with flat and cone nozzle designs using five different materials from the triboelectric series (Nylon, Polyethylene terephthalate, Polyethylene-High density, Polypropylene copolymer and Polytetrafluoroethylene). The electrostatic charge profiles of pMDI containing beclomethasone dipropionate (BDP) as model drug in HFA-134a propellant, with different concentrations of ethanol were studied. Electrostatic measurements were taken using a modified electrical low-pressure impactor (ELPI) and the deposited drug mass assayed chemically using HPLC. The charge profiles of HFA 134a alone have shown strong electronegativity with all actuator materials and nozzle designs, at an average of -1531.34 pC ± 377.34. The presence of co-solvent ethanol significantly reduced the negative charge magnitude. BDP reduced the suppressing effect of ethanol on the negative charging of the propellant. For all tested formulations, the flat nozzle design showed no significant differences in net charge between different actuator materials, whereas the charge profiles of cone designs followed the triboelectric series. The electrostatic charging profiles from a solution pMDI containing BDP and ethanol can be significantly influenced by the actuator material, nozzle design and formulation components. Ethanol concentration appears to have the most significant impact. Furthermore, BDP interactions with ethanol and HFA have an influence on the electrostatic charge of aerosols. By choosing different combinations of actuator materials and orifice design, the fine particle fractions of formulations can be altered.

Perennial allergic rhinitis (PAR) exerts significant quality-of-life and economic burdens on society. Beclomethasone dipropionate (BDP) nasal aerosol is the first nonaqueous, hydrofluoroalkane-propelled intranasal corticosteroid approved for patients in the United States to treat PAR and seasonal allergic rhinitis. To evaluate real-world effectiveness of BDP nasal aerosol from the patient's perspective by using a postmarketing observational registry. Patients (N = 824) from 43 U.S. study sites completed monthly patient-reported outcome instruments, including the Rhinitis Control Assessment Test (primary outcome variable), Treatment Satisfaction Questionnaire for Medication, Work Productivity and Activity Impairment Questionnaire plus Classroom Impairment Questions: Allergy-Specific, Pittsburgh Sleep Quality Index, and Mini Rhinoconjunctivitis Quality of Life Questionnaire for 6 months. The primary outcome assessment (Rhinitis Control Assessment Test score) (N = 527) indicated significant symptomatic improvement over baseline beginning at month 1 (p < 0.001), with >78.8% of respondents who achieved clinically meaningful improvement over 6 months. Secondary outcome measures Mini Rhinoconjunctivitis Quality of Life Questionnaire (p < 0.001), Pittsburgh Sleep Quality Index (p < 0.001), and Treatment Satisfaction Questionnaire for Medication-9 scales of effectiveness (p < 0.001), global satisfaction (p = 0.001), and patient-rated convenience (p = 0.03), significantly increased from baseline to month 6. Five of seven measurements of the Work Productivity and Activity Impairment Questionnaire plus Classroom Impairment Questions: Allergy-Specific, with the exception of work time missed and class time missed, were significantly (p < 0.001) improved in patients treated with BDP compared with baseline. Treatment with nonaqueous BDP nasal aerosol in a real-world setting significantly improved PAR symptoms and measures of quality of life, work, and school-related activities, and is associated with high patient satisfaction, reduced productivity loss and activity impairment, and improvement in sleep quality.

In order to determine whether interferon-gamma (IFN-gamma) inhibits eosinphil infiltration in the trachea of asthmatic guinea pigs induced by Rhizopus nigricans. We had administered aerosolized rIFN-gamma in the tracheas of 30 sensitized guinea pigs which had been divided into six groups, then teated animal inhaled rIFN-gamma of 5 x 10(4), 20 x 10(4), and 40 x 10(4) concentration, BDP and normal saline respectively at 24 h, 12 h, 2 h before being challenged. (1) Provocation positive rates decreased in 40 x 10(4) rIFN-gamma and BDP group compared with that in normal saline group and before intervention (P < 0.05), airway resistence decreased (P < 0.01). (2) The administration of aerosolized rIFN-gamma (40 x 10(4)) and BDP also decreased fungus-induced eosnophils but not other cells infiltration in the trachea. (3) In BALF, Eos count and ECP level were obviously lower than those in other groups. However, eosinophil numbers did not show significant change in the peripheral blood. Local administration of rIFN-gamma (40 x 10(4)) may reduce airway inflammation and intervene asthmatic attack by inhibition of Eos, ECP infiltration in airways.

Crossover from isotropic to directed percolation

We generalize the directed percolation (DP) model by relaxing the strict directionality of DP such that propagation can occur in either direction but with anisotropic probabilities. We denote the probabilities as p↓=ppd and p↑=p(1-pd), with p representing the average occupation probability and pd controlling the anisotropy. The Leath-Alexandrowicz method is used to grow a cluster from an active seed site. We call this model with two main growth directions biased directed percolation (BDP). Standard isotropic percolation (IP) and DP are the two limiting cases of the BDP model, corresponding to pd=1/2 and pd=0,1 respectively. In this work, besides IP and DP, we also consider the 1/2

A general methodology for population analysis

Lazov, Petar; Lazov, Igor

2014-12-01

For a given population with N - current and M - maximum number of entities, modeled by a Birth-Death Process (BDP) with size M+1, we introduce utilization parameter ρ, ratio of the primary birth and death rates in that BDP, which, physically, determines (equilibrium) macrostates of the population, and information parameter ν, which has an interpretation as population information stiffness. The BDP, modeling the population, is in the state n, n=0,1,…,M, if N=n. In presence of these two key metrics, applying continuity law, equilibrium balance equations concerning the probability distribution pn, n=0,1,…,M, of the quantity N, pn=Prob{N=n}, in equilibrium, and conservation law, and relying on the fundamental concepts population information and population entropy, we develop a general methodology for population analysis; thereto, by definition, population entropy is uncertainty, related to the population. In this approach, what is its essential contribution, the population information consists of three basic parts: elastic (Hooke's) or absorption/emission part, synchronization or inelastic part and null part; the first two parts, which determine uniquely the null part (the null part connects them), are the two basic components of the Information Spectrum of the population. Population entropy, as mean value of population information, follows this division of the information. A given population can function in information elastic, antielastic and inelastic regime. In an information linear population, the synchronization part of the information and entropy is absent. The population size, M+1, is the third key metric in this methodology. Namely, right supposing a population with infinite size, the most of the key quantities and results for populations with finite size, emerged in this methodology, vanish.

Singlet and triplet excitation management in a bichromophoric near-infrared-phosphorescent BODIPY-benzoporphyrin platinum complex

Multichromophoric arrays provide one strategy for assembling molecules with intense absorptions across the visible spectrum but are generally focused on systems that efficiently produce and manipulate singlet excitations and therefore are burdened by the restrictions of (a) unidirectional energy transfer and (b) limited tunability of the lowest molecular excited state. In contrast, we present here a multichromophoric array based on four boron dipyrrins (BODIPY) bound to a platinum benzoporphyrin scaffold that exhibits intense panchromatic absorption and efficiently generates triplets. The spectral complementarity of the BODIPY and porphryin units allows the direct observation of fast bidirectional singlet and triplet energy transfermore » processes (k ST( 1BDP→ 1Por) = 7.8 × 10 11 s -1, k TT( 3Por→ 3BDP) = 1.0 × 10 10 s -1, k TT( 3BDP→ 3Por) = 1.6 × 10 10 s -1), leading to a long-lived equilibrated [ 3BDP][Por]⇌[BDP][ 3Por] state. This equilibrated state contains approximately isoenergetic porphyrin and BODIPY triplets and exhibits efficient near-infrared phosphorescence (λ em = 772 nm, Φ = 0.26). Taken together, these studies show that appropriately designed triplet-utilizing arrays may overcome fundamental limitations typically associated with core-shell chromophores by tunable redistribution of energy from the core back onto the antennae.« less

Dispersibility of lactose fines as compared to API in dry powders for inhalation.

PubMed

Thalberg, Kyrre; Åslund, Simon; Skogevall, Marcus; Andersson, Patrik

2016-05-17

This work investigates the dispersion performance of fine lactose particles as function of processing time, and compares it to the API, using Beclomethasone Dipropionate (BDP) as model API. The total load of fine particles is kept constant in the formulations while the proportions of API and lactose fines are varied. Fine particle assessment demonstrates that the lactose fines have higher dispersibility than the API. For standard formulations, processing time has a limited effect on the Fine Particle Fraction (FPF). For formulations containing magnesium stearate (MgSt), FPF of BDP is heavily influenced by processing time, with an initial increase, followed by a decrease at longer mixing times. An equation modeling the observed behavior is presented. Surprisingly, the dispersibility of the lactose fines present in the same formulation remains unaffected by mixing time. Magnesium analysis demonstrates that MgSt is transferred to the fine particles during the mixing process, thus lubrication both BDP and lactose fines, which leads to an increased FPF. Dry particle sizing of the formulations reveals a loss of fine particles at longer mixing times. Incorporation of fine particles into the carrier surfaces is believed to be behind this, and is hence a mechanism of importance as regards the dispersion performance of dry powders for inhalation.

Non-ionic surfactant vesicles in pulmonary glucocorticoid delivery: characterization and interaction with human lung fibroblasts.

Non-ionic surfactant vesicles (NSVs) were proposed for the pulmonary delivery of glucocorticoids such as beclomethasone dipropionate (BDP) for the treatment of inflammatory lung diseases, e.g. asthma, chronic obstructive pulmonary disease and various type of pulmonary fibrosis. The thin layer evaporation method followed by sonication was used to prepare small non-ionic surfactant vesicles containing beclomethasone dipropionate. Light scattering experiments showed that beclomethasone dipropionate-loaded non-ionic surfactant vesicles were larger than unloaded ones and showed a significant (P<0.001) decrease of the zeta potential. The morphological analysis, by freeze-fracture transmission electron microscopy, showed the maintenance of a vesicular structure in the presence of the drug. The colloidal and storage stability were evaluated by Turbiscan Lab Expert, which evidenced the good stability of BDP-loaded non-ionic surfactant vesicles, thus showing no significant variations of mean size and no colloidal phase segregation. Primary human lung fibroblast (HLF) cells were used for in vitro investigation of vesicle tolerability, carrier-cell interaction, intracellular drug uptake and drug-loaded vesicle anti-inflammatory activity. The investigated NSVs did not show a significant cytotoxic activity at all incubation times for concentrations ranging from 0.01 to 1 μM. Confocal laser scanning microscopy showed vesicular carrier localization at the level of the cytoplasm compartment, where the glucocorticoid receptor (target site) is localized. BDP-loaded non-ionic surfactant vesicles elicited a significant improvement of the HLF intracellular uptake of the drug with respect to the free drug solution, drug/surfactant mixtures and empty vesicles used as references. The treatment of HLF cells with BDP-loaded non-ionic surfactant vesicles determined a noticeable increase of the drug anti-inflammatory activity by reducing the secretion of both constitutive and interleukin-1β-stimulated nerve growth factor (as inflammatory index) of 68% and 85%, respectively. Obtained data indicate that the investigated NSVs represent a promising tool as a pulmonary drug delivery system. Copyright © 2010 Elsevier B.V. All rights reserved.

An improved model for the combustion of AP composite propellants

1981-01-01

This paper presents several improvements to the BDP model of steady-state burning of AP composite solid propellants. The Price-Boggs-Derr model of AP monopropellant burning is incorporated to represent the AP. A separate energy equation is written for the binder to permit a different surface temperature from the AP; this includes an analysis of the sharing of primary diffusion flame energy, and correction of a BDP model inconsistency in treating the binder regression rate. A method for assembling component contributions to calculate the burning rates of multimodal propellants is also presented. Results are shown in the form of representative burning rate curves, comparisons with data, and calculated internal details of interest. Ideas for future work are discussed in an Appendix.

Na-APR-1(M74) is an aspartic protease that is rendered enzymatically inactive by site-directed mutagenesis and is a candidate antigen component in the Human Hookworm Vaccine. The mutant protease exerts vaccine efficacy by inducing antibodies that neutralize the enzymatic activity of wild type enzyme (Na-APR-1wt) in the gut of the hookworm, thereby depriving the worm of its ability to digest its blood meal. Previously, canines immunized with Na-APR-1(M74) and challenged with Ancylostoma caninum were partially protected against hookworm challenge infection, especially from the loss in hemoglobin observed in control canines and canine immunoglobulin (Ig) G raised against Na-APR-1 was shown to inhibit the enzymatic activity of Na-APR-1 wt in vitro, thereby providing proof of concept of Na-APR-1(M74) as a vaccine antigen. The mutated version, Na-APR-1(M74), was then expressed at the cGMP level using a Nicotiana benthamiana expression system (Fraunhofer, CMB, Delaware, MD), formulated with Alhydrogel®, and used to immunize mice in a dose-ranging study to explore the enzyme-neutralizing capacity of the resulting anti- Na-APR-1(M74) IgG. As little as 0.99 μg of recombinant Na-APR-1(M74) could induce anti Na-APR-1(M74) IgG in mice that were capable of inhibiting Na-APR-1w t-mediated digestion of a peptide substrate by 89%. In the absence of enzymatic activity of Na-APR-1(M74) as a surrogate marker of protein functionality, we developed an assay based on the binding of a quenched fluorescence-labeled inhibitor of aspartic proteases, BODIPY-FL pepstatin A (BDP). Binding of BDP in the active site of Na-APR-1 wt was demonstrated by inhibition of enzymatic activity, and competitive binding with unlabelled pepstatin A. BDP also bound to Na-APR-1(M74) which was assessed by fluorescence polarization, but with an ∼ 50-fold reduction in the dissociation constant. Taken together, these assays comprise a "toolbox" that could be useful for the analyses of Na-APR-1(M74) as it proceeds through the clinical development as part of the Human Hookworm Vaccine pipeline.

Taken together, these assays comprise a “toolbox” that could be useful for the analyses of Na-APR-1M74 as it proceeds through the clinical development as part of the Human Hookworm Vaccine pipeline.

Topical 5-aminosalicylic acid (5-ASA) and corticosteroids are used frequently in the treatment of active distal ulcerative colitis (UC). Our study aimed to determine the efficacy and safety of different topical drugs used to treat active distal UC. A random-effects model within a Bayesian framework was utilized to compare treatment effects and safety as odds ratios (ORs) with corresponding 95% credible intervals (CrI). The surface under the cumulative ranking area (SUCRA) and median rank (MR) with corresponding 95% CrI were calculated to rank the treatment outcomes. In the induction of clinical and endoscopic remission, most regimens showed significant advantages over placebo except topical budesonide 0.5 mg/d and hydrocortisone 100 mg/d. According to SUCRA and MR values, rectal 5-ASA 1.5 to 2.0 g/d + Beclomethasone dipropionate (BDP) 3 mg/d rendered the highest probability of being the best regimen to achieve clinical and endoscopic remission, followed by the separate use of 5-ASA 4 g/d and BDP 3 mg/d. The occurrence of adverse events was not significantly different between each treatments and placebo. In conclusion, the combined use of topical 5-ASA and BDP proved to be the best choice for active distal UC and further well-designed researches are warranted to assess its efficacy and safety.

Mono- and di-AcO substituted BODIPYs (1 and 2) were synthesized from TM-BDP. The structures of 1 and 2 were supported by single crystal X-ray analysis. Both 1 and 2 possess a large absorption coefficient, high fluorescence quantum yield, and high light stability. Compound 2 has much improved water solubility which is highly desirable for biological applications. Theoretical calculation supports our observations in X-ray analysis, absorption, and cyclic voltammetry. © 2011 American Chemical Society

Diseases affecting posterior eye segment, like macular edema, infection and neovascularization, may cause visual impairment. Traditional treatments, such as steroidal-drugs intravitreal injections, involve chronic course of therapy usually over a period of years. Moreover, they can require frequent administrations of drug in order to have an adequately disease control. This dramatically reduce patient's compliance. Efforts have been made to develop implantable devices that offer an alternative therapeutic approach to bypass many challenges of conventional type of therapy. Implantable drug delivery systems (DDS) have been developed to optimize therapeutic properties of drugs and ensure their slow release in the specific site. Polymeric materials can play an essential role in modulating drug delivery and their use in such field has become indispensable. During last decades, acrylic polymers have obtained growing interest. Biocompatibility and chemical properties make them extremely versatile, allowing their use in many field such as biomedical. In particular, block methacrylate copolymer with a balance of hydrophilic and hydrophobic properties can be suitable for prolonged DDS in biomedical devices. In this work, we focused on the realization of a system for controlled and long term release of betamethasone 17,21-dipropionate (BDP), a cortisone drug, from methacrylic block copolymers, to be tested in the treatment of the posterior eye's diseases. Different series of methyl methacrylate/hydroxyethyl methacrylate (MMA/HEMA) block and random copolymers, with different monomer compositions (10-60% HEMA), were synthetized by Atom Transfer Radical Polymerization (ATRP) to find the best hydrophilic/hydrophobic ratio, able to ensure optimal kinetic release. Copolymer samples were characterized by NMR spectroscopy (1H-NMR, 13C-NMR, CosY), SEC, TGA and DSC. Monitoring of drug release from films loaded with BDP was carried out by HPLC analysis. Evaluation of different kinetic models allowed to deduce that release of BDP is controlled over time from PMMA-b-PHEMA 53/47. In particular, PMMA-b-PHEMA 53/47 showed the best release profile to achieve the therapeutic reference dose of 3 µg/die, employed in treatment of posterior eye disease, up to four months. Accordingly, PMMA-b-PHEMA 53/47 has been tested to prepare ocular inserts. Ocular inserts with different shape and the same area of polymer films have been obtained using silicon moulds made by a 3D printer.

The Open Commons Consortium (OCC) is one of the five "Data Alliance" anchoring institutions in the NOAA Big Data Project (BDP) that was announced on April 21st, 2015. This study will present lessons learned from the first year of the BDP. The project so far has set up a pilot data commons with some initial datasets and established a digital ID service. Demonstrations on how to work with the digital ID service and the NEXRAD radar data will be shown. The proof of concept for the OCC NOAA Data Commons was established using the level 2 NEXRAD data made available to the BDP partners. Approximately 50 TiB of NEXRAD data representing the year 2015 was incorporated into the data commons. The digital ID service supports a common persistent data ID that can access data from across multiple data locations. Using this digital ID service allows users to access the NEXRAD data from their choice of the OCC NOAA Data Commons or from Amazon's NEXRAD data holdings in the same manner. To demonstrate the concept further, a sample Jupyter notebook was created to utilize the data. The notebook, which uses the Py-ART package, creates an animated loop of the NEXRAD data showing a Mayfly hatch in Wisconsin during June 2015. The notebook also demonstrates how to do a basic quality control procedure on the radar data, in this instance to remove meteorological echoes in favor of showcasing the biological scatters. For grantees on the Open Science Data Cloud there are additional premade resources available such as virtual machine images preloaded with the tools needed to access the NEXRAD data.

As a cleaner, cheaper, and more globally evenly distributed fuel, natural gas has considerable environmental, economic, and political advantages over petroleum as a source of energy for the transportation sector. Despite these benefits, its low volumetric energy density at ambient temperature and pressure presents substantial challenges, particularly for light-duty vehicles with little space available for on-board fuel storage. Adsorbed natural gas systems have the potential to store high densities of methane (CH4, the principal component of natural gas) within a porous material at ambient temperature and moderate pressures. Although activated carbons, zeolites, and metal-organic frameworks have been investigated extensively for CH4 storage, there are practical challenges involved in designing systems with high capacities and in managing the thermal fluctuations associated with adsorbing and desorbing gas from the adsorbent. Here, we use a reversible phase transition in a metal-organic framework to maximize the deliverable capacity of CH4 while also providing internal heat management during adsorption and desorption. In particular, the flexible compounds Fe(bdp) and Co(bdp) (bdp2- = 1,4-benzenedipyrazolate) are shown to undergo a structural phase transition in response to specific CH4 pressures, resulting in adsorption and desorption isotherms that feature a sharp ‘step’. Such behaviour enables greater storage capacities than have been achieved for classical adsorbents, while also reducing the amount of heat released during adsorption and the impact of cooling during desorption. The pressure and energy associated with the phase transition can be tuned either chemically or by application of mechanical pressure.

The Baikal Drilling Project (BDP) is a multinational effort to investigate the paleoclimatic history and tectonic evolution of the Baikal sedimentary basin during the Late Neogene. In March 1993 the Baikal drilling system was successfuly deployed from a barge frozen into position over a topographic high, termed the Buguldeika saddle, in the southern basin of Lake Baikal. The BDP-93 scientific team, made up of Russian, American and Japanese scientists, successfully recovered the first long (>100 m) hydraulic piston cores from two holes in 354 m of water. High quality cores of 98 m (Hole 1) and 102 m (Hole 2), representing sedimentation over the last 500,000 years, were collected in 78 mm diameter plastic liners with an average recovery of 72% and 90%, respectively. Magnetic susceptibility logging reveals an excellent hole-to-hole correlation. In this report the scientific team describes the preliminary analytical results from BDP-93 hole 1 cores. Radiocarbon dating by accelerator mass spectrometry provides an accurate chronology for the upper portion of Hole 1. Detailed lithologic characteristics, rock magnetic properties and inorganic element distributions show a significant change to the depositional environment occuring at 50 m subbottom depth, approximately 250,000 BP. This change may be due to uplift and rotation of the horst block in the Buguldeika saddle. The sedimentary section above 50 m is pelitic with varve-like laminae, whereas the section below 50 m contains a high proportion of sand and gravel horizons often organized into turbidite sequences. Accordingly, high resolution seismic records reveal a change in sonic velocity at this depth. It is inferred that sedimentation prior to 250 ka BP was from the west via the Buguldeika river system. After 250 ka BP the Buguldeika saddle reflects an increase in hemipelagic sediments admixed with fine-grained material from the Selenga River drainage basin, east of Lake Baikal. Variations in the spore-pollen assemblage, diatoms, biogenic silica content, rock magnetic properties, clay mineralogy and organic carbon in the upper 50 m of BDP-93-1 reveal a detailed record of climate change over approximately the last 250,000 years. These variables alternate in a pattern characteristic of glacial/interglacial climatic fluctuations. The present age model suggests that the climate signal recorded in Lake Baikal sediments is similar to Late Quaternary signals recorded in Chinese loess sections and in marine sediments.

The aim of this study was to determine the output of salbutamol nebulised in combination with either flunisolide or beclometasone dipropionate (BDP) from two different nebulisers under simulated breathing conditions. The BimboNeb and Nebula nebulisers were used to nebulise 3.0 mL of the two drug mixtures (salbutamol, 5000 microg plus either flunisolide, 600 microg, or BDP, 800 microg). Particle size was determined by inertial impaction. Total outputs of all drugs from both nebulisers were measured using a sinus flow pump under simulated paediatric and adult breathing patterns. The mass median aerodynamic diameter (MMAD) of BDP particles from the mixture was 6.34 mum using the BimboNeb and 5.34 mum using the Nebula. Values for salbutamol in this mixture were 3.93 and 3.32 microm, respectively. The MMAD of flunisolide particles from the BimboNeb and Nebula were 3.74 and 3.65 microm, respectively, while for salbutamol were 3.79 and 3.74 microm, respectively. With the simulated adult breathing pattern, all drug outputs from both mixtures were greater from the BimboNeb than from the Nebula after 5 and 10 min' nebulisation. Drug delivery from the BimboNeb, but not the Nebula, was affected by the simulated breathing pattern. Outputs with the BimboNeb were lower with the paediatric breathing pattern than with the adult pattern. In the majority of cases, nebulising for 10 min produced significantly greater drug output than after 5 min. For the Nebula, outputs were generally similar at 5 and 10 min, irrespective of the breathing pattern. These results highlight the need to assess the amount of aerosolised drug available when drugs are combined, when different nebulisers are used and when they are used with patients of different ages.

The Barcode of Life Data Portal: Bridging the Biodiversity Informatics Divide for DNA Barcoding

With the volume of molecular sequence data that is systematically being generated globally, there is a need for centralized resources for data exploration and analytics. DNA Barcode initiatives are on track to generate a compendium of molecular sequence–based signatures for identifying animals and plants. To date, the range of available data exploration and analytic tools to explore these data have only been available in a boutique form—often representing a frustrating hurdle for many researchers that may not necessarily have resources to install or implement algorithms described by the analytic community. The Barcode of Life Data Portal (BDP) is a first step towards integrating the latest biodiversity informatics innovations with molecular sequence data from DNA barcoding. Through establishment of community driven standards, based on discussion with the Data Analysis Working Group (DAWG) of the Consortium for the Barcode of Life (CBOL), the BDP provides an infrastructure for incorporation of existing and next-generation DNA barcode analytic applications in an open forum.

Anti-infective activity of apolipoprotein domain derived peptides in vitro: identification of novel antimicrobial peptides related to apolipoprotein B with anti-HIV activity

PubMed Central

2010-01-01

Background Previous reports have shown that peptides derived from the apolipoprotein E receptor binding region and the amphipathic α-helical domains of apolipoprotein AI have broad anti-infective activity and antiviral activity respectively. Lipoproteins and viruses share a similar cell biological niche, being of overlapping size and displaying similar interactions with mammalian cells and receptors, which may have led to other antiviral sequences arising within apolipoproteins, in addition to those previously reported. We therefore designed a series of peptides based around either apolipoprotein receptor binding regions, or amphipathic α-helical domains, and tested these for antiviral and antibacterial activity. Results Of the nineteen new peptides tested, seven showed some anti-infective activity, with two of these being derived from two apolipoproteins not previously used to derive anti-infective sequences. Apolipoprotein J (151-170) - based on a predicted amphipathic alpha-helical domain from apolipoprotein J - had measurable anti-HSV1 activity, as did apolipoprotein B (3359-3367) dp (apoBdp), the latter being derived from the LDL receptor binding domain B of apolipoprotein B. The more active peptide - apoBdp - showed similarity to the previously reported apoE derived anti-infective peptide, and further modification of the apoBdp sequence to align the charge distribution more closely to that of apoEdp or to introduce aromatic residues resulted in increased breadth and potency of activity. The most active peptide of this type showed similar potent anti-HIV activity, comparable to that we previously reported for the apoE derived peptide apoEdpL-W. Conclusions These data suggest that further antimicrobial peptides may be obtained using human apolipoprotein sequences, selecting regions with either amphipathic α-helical structure, or those linked to receptor-binding regions. The finding that an amphipathic α-helical region of apolipoprotein J has antiviral activity comparable with that for the previously reported apolipoprotein AI derived peptide 18A, suggests that full-length apolipoprotein J may also have such activity, as has been reported for full-length apolipoprotein AI. Although the strength of the anti-infective activity of the sequences identified was limited, this could be increased substantially by developing related mutant peptides. Indeed the apolipoprotein B-derived peptide mutants uncovered by the present study may have utility as HIV therapeutics or microbicides. PMID:20298574

Computational discovery of metal-organic frameworks with high gas deliverable capacity

NASA Astrophysics Data System (ADS)

Bao, Yi

Metal-organic frameworks (MOFs) are a rapidly emerging class of nanoporous materials with largely tunable chemistry and diverse applications in gas storage, gas purification, catalysis, sensing and drug delivery. Efforts have been made to develop new MOFs with desirable properties both experimentally and computationally for decades. To guide experimental synthesis, we here develop a computational methodology to explore MOFs with high gas deliverable capacity. This de novo design procedure applies known chemical reactions, considers synthesizability and geometric requirements of organic linkers, and efficiently evolves a population of MOFs to optimize a desirable property. We identify 48 MOFs with higher methane deliverable capacity at 65-5.8 bar condition than the MOF-5 reference in nine networks. In a more comprehensive work, we predict two sets of MOFs with high methane deliverable capacity at a 65-5.8 bar loading-delivery condition or a 35-5.8 bar loading-delivery condition. We also optimize a set of MOFs with high methane accessible internal surface area to investigate the relationship between deliverable capacities and internal surface area. This methodology can be extended to MOFs with multiple types of linkers and multiple SBUs. Flexibile MOFs may allow for sophisticated heat management strategies and also provide higher gas deliverable capacity than rigid frameworks. We investigate flexible MOFs, such as MIL-53 families, and Fe(bdp) and Co(bdp) analogs, to understand the structural phase transition of frameworks and the resulting influence on heat of adsorption. Challenges of simulating a system with a flexible host structure and incoming guest molecules are discussed. Preliminary results from isotherm simulation using the hybrid MC/MD simulation scheme on MIL-53(Cr) are presented. Suggestions for proceeding to understand the free energy profile of flexible MOFs are provided.

This study examined hippocampal volume as a putative biomarker for psychotic illness in the Bipolar-Schizophrenia Network on Intermediate Phenotypes (B-SNIP) psychosis sample, contrasting manual tracing and semiautomated (FreeSurfer) region-of-interest outcomes. The study sample (n = 596) included probands with schizophrenia (SZ, n = 71), schizoaffective disorder (SAD, n = 70), and psychotic bipolar I disorder (BDP, n = 86); their first-degree relatives (SZ-Rel, n = 74; SAD-Rel, n = 62; BDP-Rel, n = 88); and healthy controls (HC, n = 145). Hippocampal volumes were derived from 3Tesla T1-weighted MPRAGE images using manual tracing/3DSlicer3.6.3 and semiautomated parcellation/FreeSurfer5.1,64bit. Volumetric outcomes from both methodologies were contrasted in HC and probands and relatives across the 3 diagnoses, using mixed-effect regression models (SAS9.3 Proc MIXED); Pearson correlations between manual tracing and FreeSurfer outcomes were computed. SZ (P = .0007–.02) and SAD (P = .003–.14) had lower hippocampal volumes compared with HC, whereas BDP showed normal volumes bilaterally (P = .18–.55). All relative groups had hippocampal volumes not different from controls (P = .12–.97) and higher than those observed in probands (P = .003–.09), except for FreeSurfer measures in bipolar probands vs relatives (P = .64–.99). Outcomes from manual tracing and FreeSurfer showed direct, moderate to strong, correlations (r = .51–.73, P < .05). These findings from a large psychosis sample support decreased hippocampal volume as a putative biomarker for schizophrenia and schizoaffective disorder, but not for psychotic bipolar I disorder, and may reflect a cumulative effect of divergent primary disease processes and/or lifetime medication use. Manual tracing and semiautomated parcellation regional volumetric approaches may provide useful outcomes for defining measurable biomarkers underlying severe mental illness. PMID:24557771

Background-Modeling-Based Adaptive Prediction for Surveillance Video Coding.

Zhang, Xianguo; Huang, Tiejun; Tian, Yonghong; Gao, Wen

2014-02-01

The exponential growth of surveillance videos presents an unprecedented challenge for high-efficiency surveillance video coding technology. Compared with the existing coding standards that were basically developed for generic videos, surveillance video coding should be designed to make the best use of the special characteristics of surveillance videos (e.g., relative static background). To do so, this paper first conducts two analyses on how to improve the background and foreground prediction efficiencies in surveillance video coding. Following the analysis results, we propose a background-modeling-based adaptive prediction (BMAP) method. In this method, all blocks to be encoded are firstly classified into three categories. Then, according to the category of each block, two novel inter predictions are selectively utilized, namely, the background reference prediction (BRP) that uses the background modeled from the original input frames as the long-term reference and the background difference prediction (BDP) that predicts the current data in the background difference domain. For background blocks, the BRP can effectively improve the prediction efficiency using the higher quality background as the reference; whereas for foreground-background-hybrid blocks, the BDP can provide a better reference after subtracting its background pixels. Experimental results show that the BMAP can achieve at least twice the compression ratio on surveillance videos as AVC (MPEG-4 Advanced Video Coding) high profile, yet with a slightly additional encoding complexity. Moreover, for the foreground coding performance, which is crucial to the subjective quality of moving objects in surveillance videos, BMAP also obtains remarkable gains over several state-of-the-art methods.

Folding domain B of protein A on a dynamically partitioned free energy landscape.

PubMed

Nelson, Erik D; Grishin, Nick V

2008-02-05

The B domain of staphylococcal protein A (BdpA) is a small helical protein that has been studied intensively in kinetics experiments and detailed computer simulations that include explicit water. The simulations indicate that BdpA needs to reorganize in crossing the transition barrier to facilitate folding its C-terminal helix (H3) onto the nucleus formed from helices H1 and H2. This process suggests frustration between two partially ordered forms of the protein, but recent varphi value measurements indicate that the transition structure is relatively constant over a broad range of temperatures. Here we develop a simplistic model to investigate the folding transition in which properties of the free energy landscape can be quantitatively compared with experimental data. The model is a continuation of the Muñoz-Eaton model to include the intermittency of contacts between structured parts of the protein, and the results compare variations in the landscape with denaturant and temperature to varphi value measurements and chevron plots of the kinetic rates. The topography of the model landscape (in particular, the feature of frustration) is consistent with detailed simulations even though variations in the varphi values are close to measured values. The transition barrier is smaller than indicated by the chevron data, but it agrees in order of magnitude with a similar alpha-carbon type of model. Discrepancies with the chevron plots are investigated from the point of view of solvent effects, and an approach is suggested to account for solvent participation in the model.

The efficacy of extrafine beclomethasone dipropionate–formoterol fumarate in COPD patients who are not “frequent exacerbators”: a post hoc analysis of the FORWARD study

The GOLD 2017 strategy document recommends that the pharmacological management of COPD patients be based on the risk of future exacerbations and the severity of symptoms. A threshold of two moderate exacerbations or one hospitalization is used to define high-risk patients. The FORWARD study was a randomized, double-blind, parallel-group trial that compared 48 weeks’ treatment with extrafine beclomethasone dipropionate plus formoterol fumarate (BDP-FF) versus FF in severe COPD patients with a history of one or more exacerbations in the previous year. The new GOLD 2017 recommendations mean that many patients in the FORWARD study are now reclassified as GOLD B. We conducted a post hoc analysis of the FORWARD study, in order to investigate the effects of extrafine BDP/FF in patients with one exacerbation in the previous year, focusing on those categorized as group B using the GOLD 2017 definition. The analysis showed a 35% reduction in exacerbation rate with an inhaled corticosteroid (ICS) + long-acting β-agonist (LABA) versus LABA. We propose that ICS-LABA treatment is a therapeutic option for COPD patients with one exacerbation in the previous year. PMID:29138555

An inhomogeneous time series of measurements of the percentage content of biogenic silica in the samples of joint cores BDP-96-1 and BDP-96-2 from the bottom of Lake Baikal drilled at a depth of 321 m under water has been analyzed. The composite depth of cores is 77 m, which covers the Pleistocene Epoch to 1.8 Ma. The time series was reduced to a regular form with a time step of 1 kyr, which allowed 16 distinct quasi-periodic components with periods from 19 to 251 kyr to be revealed in this series at a significance level of their amplitudes exceeding 4σ. For this, the combined spectral periodogram (a modification of the spectral analysis method) was used. Some of the revealed quasi-harmonics are related to the characteristic cyclical oscillations of the Earth's orbital parameters. Special focus was payed to the temporal change in the parameters of the revealed quasi-harmonic components over the Pleistocene Epoch, which was studied by constructing the spectral density of the analyzed data in the running window of 201 and 701 kyr.

SummaryBioavailable phosphorus (P) losses due to agriculture activity in a purple soil watershed in the Sichuan Basin of Southwestern China were monitored to define the hydrological controls of P transport. Our results indicate that the proportion of P that was transported in particulate form increased in the rainy season, and that the mass of total bioavailable P (BAP) loads exhibited seasonal fluctuations, wherein the majority (over 90%) was observed to have been exported between June and September. The proportion of bioavailable dissolved P (BDP) in the BAP discharge budget in the watershed varied between 11% and 15% during the monitoring period. The bioavailable particulate P (BPP) and BDP concentrations of stream water under rainstorm events increased by over 40% in comparison to their annual mean concentrations, and the annual BAP load was primarily dominated by the loads that occurred during rainstorm events in the study year. BAP concentration in groundwater significantly fluctuated with the seasons, and the ratio of total BAP in groundwater to that in surface water gradually increased during the rainy season. Thus, the impact of agriculture on the water quality of this watershed becomes clearly evident.

In an attempt to establish how treatment with inhaled extra-fine beclomethasone/formoterol (I-EF-BDP/F) formulation differs from other combinations of inhaled corticosteroid (ICS) and long acting beta-agonist (LABA), we studied lung function and markers of airway inflammation upon switching to the extra-fine formulation and after 8 weeks of treatment with it. We carried out a real-life clinical observation of undercontrolled asthmatic patients switched over from dry powder inhalers of fluticasone/salmeterol and budesonide/formoterol to I-EF-BDP/F (Foster(®), Chiesi Farmaceutici S.p.A., Italy). The effects of 8-weeks of treatment were documented by means of visual analog scale (VAS), quality of life by Asthma Quality of Life Questionnaire (AQLQ), spirometry and markers of airway or systemic inflammation: exhaled breath temperature (EBT), blood eosinophils (Eos), and high sensitivity C-reactive protein (CRP). Before/after treatment differences between forced vital capacity percent of predicted (%FVC), a simple indicator of small airways involvement, were calculated and subjects were ranked accordingly to reflect the magnitude of the therapeutic response. Subjects above the 75th percentile (n = 15), "top responders", were then compared with those below the 25th percentile (n = 15) "poor responders". On average, the 59 patients completing the study (mean age ± SD 51 ± 12 years, 38 women) had significant improvement in VAS and QLQ scores at the end of the treatment period (49.1 ± 2.4 vs. 73.1 ± 2.05 and 146.1 ± 2.7 vs. 176.7.1 ± 3.4 respectively, P < 0.001), but not in the inflammatory indicators (EBT, CRP and Eos). However, when comparing the "top responders" with the "poor responders", significant improvement in these inflammatory indicators was observed: EBT significantly decreased from 34.04/mean/± 0.30/s.e.m./[°C] to 33.57 ± 0.33, P = 0.003, Eos in blood fell from 381.7 ± 91.2 [cells/μL] to 244.2 ± 43.2, P = 0.02. Before/after treatment differences in hsCRP decreased significantly in the top responders compared with the poor responders (Mann-Whitney test, P = 0.04). Asthmatic subjects who had the most improvement in FVC after transition to I-EF-BDP/F from other combined ICS/LABA preparations also demonstrated a significant decrease in some indicators of airway/systemic inflammation. These results support the notion that I-EF-BDP/F exerts an effect also at the level of the small airways through a reduction of the level of air trapping. Patients in whom inflammation of the small airways plays an important clinical role are the ones to derive most benefit from this small airways tailored treatment. However, improved compliance due to the "promise of a new drug" effect should also be considered as contributing to the treatment results. Copyright © 2013 Elsevier Ltd. All rights reserved.

The NAVSTAR satellites have two missions: navigation and nuclear detonation detection. The main objective of this paper is to describe one of the key elements of the Nuclear Detonation Detection System (NDS), the Burst Detector W-Sensor (BDW) that was developed for the Air Force Space and Missle Systems Center, its mission on GPS Block IIR, and how it utilizes GPS timing signals to precisely locate nuclear detonations (NUDET). The paper will also cover the interface to the Burst Detector Processor (BDP) which links the BDW to the ground station where the BDW is controlled and where data from multiple satellitesmore » are processed to determine the location of the NUDET. The Block IIR BDW is the culmination of a development program that has produced a state-of-the-art, space qualified digital receiver/processor that dissipates only 30 Watts, weighs 57 pounds, and has a 12in. {times} l4.2in. {times} 7.16in. footprint. The paper will highlight several of the key multilayer printed circuit cards without which the required power, weight, size, and radiation requirements could not have been met. In addition, key functions of the system software will be covered. The paper will be concluded with a discussion of the high speed digital signal processing and algorithm used to determine the time-of-arrival (TOA) of the electromagnetic pulse (EMP) from the NUDET.« less

Inhaled corticosteroids (ICS) offer targeted treatment for bronchopulmonary dysplasia (BPD) with minimal systemic effects compared to systemic steroids. However, dosing of ICS in the management of infants at high-risk of developing BPD is not well established. The objective of this study was to determine an effective dose of ICS for the treatment of ventilator-dependent infants to facilitate extubation or reduce fractional inspired oxygen concentration. Forty-one infants born at < 32 weeks gestational age (GA) or < 1250 g who were ventilator-dependent at 10-28 days postnatal age were included. A non-randomized dose-ranging trial was performed using aerosolized inhaled beclomethasone with hydrofluoralkane propellant (HFA-BDP). Four dosing groups (200, 400, 600 and 800 μg twice daily for 1 week) with 11, 11, 10 and 9 infants in each group, respectively, were studied. The primary outcome was therapeutic efficacy (successful extubation or reduction in FiO 2 of > 75% from baseline) in ≥60% of infants in the group. Oxygen requirements, complications and long-term neurodevelopmental outcomes were also assessed. The median age at enrollment was 22 (10-28) postnatal days. The primary outcome, therapeutic efficacy as defined above, was not achieved in any group. However, there was a significant reduction in post-treatment FiO 2 at a dose of 800 μg bid. No obvious trends were seen in long-term neurodevelopmental outcomes. Therapeutic efficacy was not achieved with all studied doses of ICS. A significant reduction in oxygen requirements was noted in ventilator-dependent preterm infants at 10-28 days of age when given 800 μg of HFA-BDP bid. Larger randomized trials of ICS are required to determine efficacy for the management of infants at high-risk for development of BPD. This clinical trial was registered retrospectively on clinicaltrials.gov. The registration number is NCT03503994 .

A series of semi-empirical equations were utilised to design two solution based pressurised metered dose inhaler (pMDI) formulations, with equivalent aerosol performance but different physicochemical properties. Both inhaler formulations contained the drug, beclomethasone dipropionate (BDP), a volatile mixture of ethanol co-solvent and propellant (hydrofluoroalkane-HFA). However, one formulation was designed such that the emitted aerosol particles contained BDP and glycerol, a common inhalation particle modifying excipient, in a 1:1 mass ratio. By modifying the formulation parameters, including actuator orifice, HFA and metering volumes, it was possible to produce two formulations (glycerol-free and glycerol-containing) which had identical mass median aerodynamic diameters (2.4μm±0.1 and 2.5μm±0.2), fine particle dose (⩽5μm; 66μg±6 and 68μg±2) and fine particle fractions (28%±2% and 30%±1%), respectively. These observations demonstrate that it is possible to engineer formulations that generate aerosol particles with very different compositions to have similar emitted dose and in vitro deposition profiles, thus making them equivalent in terms of aerosol performance. Analysis of the physicochemical properties of each formulation identified significant differences in terms of morphology, thermal properties and drug dissolution of emitted particles. The particles produced from both formulations were amorphous; however, the formulation containing glycerol generated particles with a porous structure, while the glycerol-free formulation generated particles with a primarily spherical morphology. Furthermore, the glycerol-containing particles had a significantly lower dissolution rate (7.8%±2.1%, over 180min) compared to the glycerol-free particles (58.0%±2.9%, over 60min) when measured using a Franz diffusion cell. It is hypothesised that the presence of glycerol in the emitted aerosol particles altered solubility and drug transport, which may have implications for BDP pharmacokinetics after deposition in the respiratory tract.

Neurotensin is a peptide with effects on appetite and intestinal lipid absorption. Experimental data suggest a role in glucose homeostasis, while human data is missing. Here, 20 morbidly obese subjects either underwent biliopancreatic diversion with duodenal switch (BPD), or Roux-en-Y gastric bypass (RYGB) in a randomized fashion. Before and 1 year after surgery, anthropometric data, body composition, clinical biochemistry, insulin sensitivity by means of euglycemic hyperinsulinemic clamps (HEC) and fasting plasma proneurotensin 1-117 were analyzed. Plasma proneurotensin increased significantly more 1 year after BDP than RYGB (P = 0.028), while weight loss was comparable. After metabolic surgery, proneurotensin correlated positively with insulin sensitivity (M-value) (r = 0.55, P < 0.001), while an inverse relationship with fasting glucose, HOMA-IR and HbA1c was observed (P < 0.05 for all components). After adjustment for age and gender, proneurotensin and BMI remained independently related with delta of M-value (β = 0.46 and β = 0.51, P < 0.05, resp.). From these data we conclude that proneurotensin positively correlates with insulin sensitivity uniquely after weight loss induced by metabolic surgery in humans. BDP leads to a stronger increase in the anorexigenic peptide compared to RYGB.

To investigate the influence of different actuator nozzle designs on aerosol electrostatic charges and aerosol performances for pressurised metered dose inhalers (pMDIs). Four actuator nozzle designs (flat, curved flat, cone and curved cone) were manufactured using insulating thermoplastics (PET and PTFE) and conducting metal (aluminium) materials. Aerosol electrostatic profiles of solution pMDI formulations containing propellant HFA 134a with different ethanol concentration and/or model drug beclomethasone dipropionate (BDP) were studied using a modified electrical low-pressure impactor (ELPI) for all actuator designs and materials. The mass of the deposited drug was analysed using high performance liquid chromatography (HPLC). Both curved nozzle designs for insulating PET and PTFE actuators significantly influenced aerosol electrostatics and aerosol performance compared with conducting aluminium actuator, where reversed charge polarity and higher throat deposition were observed with pMDI formulation containing BDP. Results are likely due to the changes in plume geometry caused by the curved edge nozzle designs and the bipolar charging nature of insulating materials. This study demonstrated that actuator nozzle designs could significantly influence the electrostatic charges profiles and aerosol drug deposition pattern of pMDI aerosols, especially when using insulating thermoplastic materials where bipolar charging is more dominant.

In this study, a niosome nanodispersion was manufactured using high-pressure homogenization following the hydration of proniosomes. Using beclometasone dipropionate (BDP) as a model drug, the characteristics of the homogenized niosomes were compared with vesicles prepared via the conventional approach of probe-sonication. Particle size, zeta potential, and the drug entrapment efficiency were similar for both size reduction mechanisms. However, high-pressure homogenization was much more efficient than sonication in terms of homogenization output rate, avoidance of sample contamination, offering a greater potential for a large-scale manufacturing of noisome nanodispersions. For example, high-pressure homogenization was capable of producing small size niosomes (209 nm) using a short single-step of size reduction (6 min) as compared with the time-consuming process of sonication (237 nm in >18 min) and the BDP entrapment efficiency was 29.65% ± 4.04 and 36.4% ± 2.8. In addition, for homogenization, the output rate of the high-pressure homogenization was 10 ml/min compared with 0.83 ml/min using the sonication protocol. In conclusion, a facile, applicable, and highly efficient approach for preparing niosome nanodispersions has been established using proniosome technology and high-pressure homogenization.

The aim of this study was to prepare and characterize novel hydrogels with polysaccharide-polyaminoacid structure, able to undergo an enzymatic hydrolysis in the colon and potentially useful for treating inflammatory bowel diseases (IBD). Starting materials were methacrylated dextran (DEX-MA) and methacrylated alpha,beta-poly(N-2-hydroxyethyl)-dl-aspartamide (PHM). These polymers were photocrosslinked by exposure of their aqueous solutions at 313 nm without photoinitiators. Different samples, shaped as microparticles, were obtained as a function of polymer concentration and irradiation time. FT-IR analysis confirmed the occurrence of a co-crosslinking between DEX-MA and PHM in all experimental conditions. Size analysis evidenced a narrow particle distribution and swelling studies, performed in twice-distilled water and simulated gastrointestinal fluids, showed a good affinity of these hydrogels towards the aqueous medium. DEX-MA/PHM based hydrogels undergo a negligible chemical hydrolysis, whereas they are partially degraded by dextranase. In vitro biological assays showed cell compatibility of these samples. Beclomethasone dipropionate (BDP), a drug recently proposed for the treatment of IBD was entrapped into a DEX-MA/PHM based hydrogel and its release was evaluated in the absence or in the presence of dextranase. Obtained release profiles suggest the potential use of BDP loaded DEX-MA/PHM based hydrogels for the treatment of IBD.

Reaching the native states of small proteins, a necessary step towards a comprehensive understanding of the folding mechanisms, has remained a tremendous challenge to ab initio protein folding simulations despite the extensive effort. In this work, the folding process of the B domain of protein A (BdpA) has been simulated by both conventional and replica exchange molecular dynamics using AMBER FF03 all-atom force field. Started from an extended chain, a total of 40 conventional (each to 1.0 μs) and two sets of replica exchange (each to 200.0 ns per replica) molecular dynamics simulations were performed with different generalized-Born solvation models and temperature control schemes. The improvements in both the force field and solvent model allowed successful simulations of the folding process to the native state as demonstrated by the 0.80 A˚ Cα root mean square deviation (RMSD) of the best folded structure. The most populated conformation was the native folded structure with a high population. This was a significant improvement over the 2.8 A˚ Cα RMSD of the best nativelike structures from previous ab initio folding studies on BdpA. To the best of our knowledge, our results demonstrate, for the first time, that ab initio simulations can reach the native state of BdpA. Consistent with experimental observations, including Φ-value analyses, formation of helix II/III hairpin was a crucial step that provides a template upon which helix I could form and the folding process could complete. Early formation of helix III was observed which is consistent with the experimental results of higher residual helical content of isolated helix III among the three helices. The calculated temperature-dependent profile and the melting temperature were in close agreement with the experimental results. The simulations further revealed that phenylalanine 31 may play critical to achieve the correct packing of the three helices which is consistent with the experimental observation. In addition to the mechanistic studies, an ab initio structure prediction was also conducted based on both the physical energy and a statistical potential. Based on the lowest physical energy, the predicted structure was 2.0 A˚ Cα RMSD away from the experimentally determined structure.

Probing sequence dependence of folding pathway of α-helix bundle proteins through free energy landscape analysis.

PubMed

Shao, Qiang

2014-06-05

A comparative study on the folding of multiple three-α-helix bundle proteins including α3D, α3W, and the B domain of protein A (BdpA) is presented. The use of integrated-tempering-sampling molecular dynamics simulations achieves reversible folding and unfolding events in individual short trajectories, which thus provides an efficient approach to sufficiently sample the configuration space of protein and delineate the folding pathway of α-helix bundle. The detailed free energy landscape analyses indicate that the folding mechanism of α-helix bundle is not uniform but sequence dependent. A simple model is then proposed to predict folding mechanism of α-helix bundle on the basis of amino acid composition: α-helical proteins containing higher percentage of hydrophobic residues than charged ones fold via nucleation-condensation mechanism (e.g., α3D and BdpA) whereas proteins having opposite tendency in amino acid composition more likely fold via the framework mechanism (e.g., α3W). The model is tested on various α-helix bundle proteins, and the predicted mechanism is similar to the most approved one for each protein. In addition, the common features in the folding pathway of α-helix bundle protein are also deduced. In summary, the present study provides comprehensive, atomic-level picture of the folding of α-helix bundle proteins.

Distracting emotional information impairs attention more in schizophrenia (SCZ) than in never-psychotic individuals. However, it is unclear whether this impairment and its neural circuitry is indicative generally of psychosis, or specifically of SCZ, and whether it is even more specific to certain SCZ symptoms (eg, deficit syndrome). It is also unclear if this abnormality contributes to impaired behavioral performance and real-world functioning. Functional imaging data were recorded while individuals with SCZ, bipolar disorder with psychosis (BDP) and no history of psychotic disorders (CON) attended to identity of faces while ignoring their emotional expressions. We examined group differences in functional connectivity between amygdala, involved in emotional evaluation, and sub-regions of medial prefrontal cortex (MPFC), involved in emotion regulation and cognitive control. Additionally, we examined correlation of this connectivity with deficit syndrome and real-world functioning. Behaviorally, SCZ showed the worst accuracy when matching the identity of emotional vs neutral faces. Neurally, SCZ showed lower amygdala-MPFC connectivity than BDP and CON. BPD did not differ from CON, neurally or behaviorally. In patients, reduced amygdala-MPFC connectivity during emotional distractors was related to worse emotional vs neutral accuracy, greater deficit syndrome severity, and unemployment. Thus, reduced amygdala-MPFC functional connectivity during emotional distractors reflects a deficit that is specific to SCZ. This reduction in connectivity is associated with worse clinical and real-world functioning. Overall, these findings provide support for the specificity and clinical utility of amygdala-MPFC functional connectivity as a potential neural marker of SCZ. PMID:26908926

Three conjugated pigment molecules with fused hydrogen bonds, 3,7-diphenylpyrrolo[2,3-f]indole-2,6(1H,5H)-dione (BDP), (E)-6,6'-dibromo-[3,3'-biindolinylidene]-2,2'-dione (IIDG), and 3,6-di(thiophen-2-yl)-2,5-dihydropyrrolo-[3,4-c]pyrrole-1,4-dione (TDPP), were studied in this work. The insoluble pigment molecules were functionalized with tert-butoxylcarbonyl (t-Boc) groups to form soluble pigment precursors (BDP-Boc, IIDG-Boc, and TDPP-Boc) with latent hydrogen bonding. The single crystals of soluble pigment precursors were obtained. Upon simple thermal annealing, the t-Boc groups were removed and the soluble pigment precursor molecules with latent hydrogen bonding were converted into the original pigment molecules with fused hydrogen bonding. Structural analysis indicated that the highly crystalline soluble precursors were directly converted into highly crystalline insoluble pigments, which are usually only achievable by gas-phase routes like physical vapor transport. The distinct crystal structure after the thermal annealing treatment suggests that fused hydrogen bonding is pivotal for the rearrangement of molecules to form a new crystal in solid state, which leads to over 2 orders of magnitude enhancement in charge mobility in organic field-effect transistor (OFET) devices. This work demonstrated that crystalline OFET devices with insoluble pigment molecules can be fabricated by their soluble precursors. The results indicated that a variety of commercially available conjugated pigments could be potential active materials for high-performance OFETs.

Regulation of TFIIIB during F9 cell differentiation.

2010-03-12

Differentiation of F9 embryonal carcinoma (EC) cells into parietal endoderm (PE) provides a tractable model system for studying molecular events during early and inaccessible stages of murine development. PE formation is accompanied by extensive changes in gene expression both in vivo and in culture. One of the most dramatic is the ~10-fold decrease in transcriptional output by RNA polymerase (pol) III. This has been attributed to changes in activity of TFIIIB, a factor that is necessary and sufficient to recruit pol III to promoters. The goal of this study was to identify molecular changes that can account for the low activity of TFIIIB following F9 cell differentiation. Three essential subunits of TFIIIB decrease in abundance as F9 cells differentiate; these are Brf1 and Bdp1, which are pol III-specific, and TBP, which is also used by pols I and II. The decreased levels of Brf1 and Bdp1 proteins can be explained by reduced expression of the corresponding mRNAs. However, this is not the case for TBP, which is regulated post-transcriptionally. In proliferating cells, pol III transcription is stimulated by the proto-oncogene product c-Myc and the mitogen-activated protein kinase Erk, both of which bind to TFIIIB. However, c-Myc levels fall during differentiation and Erk becomes inactive through dephosphorylation. The diminished abundance of TFIIIB is therefore likely to be compounded by changes to these positive regulators that are required for its full activity. In addition, PE cells have elevated levels of the retinoblastoma protein RB, which is known to bind and repress TFIIIB. The low activity of TFIIIB in PE can be attributed to a combination of changes, any one of which could be sufficient to inhibit pol III transcription. Declining levels of essential TFIIIB subunits and of activators that are required for maximal TFIIIB activity are accompanied by an increase in a potent repressor of TFIIIB. These events provide fail-safe guarantees to ensure that pol III output is appropriate to the diminished metabolic requirements of terminally differentiated cells.

1. Three experiments of 39 d were simultaneously conducted to assess the efficacy of three carbohydrase combinations on performance, apparent nutrient digestibility, intestinal morphology and digestive organ relative weights of chickens fed on a wheat-based diet. 2. Experiment 1 was performed under laboratory conditions, with the birds housed in cages. In experiment 2, the birds were placed in floor pens built in a commercial farm, and raised with their contemporaries at the farm. In experiment 3, broilers were reared under industrial management circumstances in commercial farms. A two-phase feeding programme was used: starter from 1 to 21 d of age and finisher from 22 to 39 d. The basal diet without supplementation (BD) and three enzyme preparations (BDF, BDP and BDR) were evaluated. 3. No differences in growth traits were observed among treatments in experiments 1 and 2. 4. When overall growing period was evaluated, all enzyme combinations improved apparent DM ileal digestibility of feed in the three experiments, but significant differences were only found in experiments 2 and 3. For this same period, an increase in apparent CP ileal digestibility of broiler chickens fed supplemented diets against the control group was found in experiment 3. Moreover, a significant greater apparent ileal fat digestibility in the enzyme treatments compared with the control group was shown when broilers were raised under industrial conditions (experiment 3). 5. Enzyme combinations had no effect on villus heights and crypt depths of broilers in experiment 1, whereas, in experiment 2, a greater villus height was found in BDF and BDP treatments than in control birds. 6. There were no differences in digestive organ relative weights among dietary treatments except for pancreas in experiment 1.

Two members, Bright/ARID3A and Bdp/ARID3B, of the ARID (AT-Rich Interaction Domain) transcription family are distinguished by their ability to specifically bind to DNA and to self-associate via a second domain, REKLES. Bright and Bdp positively regulate immunoglobulin heavy chain gene (IgH) transcription by binding to AT-rich motifs within Matrix Associating Regions (MARs) residing within a subset of VH promoters and the Eµ intronic enhancer. In addition, REKLES provides Bright nuclear export function, and a small pool of Bright is directed to plasma membrane sub-domains/lipid rafts where it associates with and modulates signaling of the B cell antigen receptor (BCR). Here, we characterize a third, highly conserved, physically condensed ARID3 locus, Brightlike/ARID3C. Brightlike encodes two alternatively spliced, SUMO-I-modified isoforms that include or exclude (Δ6) the REKLES-encoding exon 6. Brightlike transcripts and proteins are expressed preferentially within B lineage lymphocytes and coordinate with highest Bright expression--in activated follicular B cells. Brightlike, but not BrightlikeΔ6, undergoes nuclear-cytoplasmic shuttling with a fraction localizing within lipid rafts following BCR stimulation. Brightlike, but not BrightlikeΔ6, associates with Bright in solution, at common DNA binding sites in vitro, and is enriched at Bright binding sites in chromatin. Although possessing little transactivation capacity of its own, Brightlike significantly co-activates Bright-dependent IgH transcription with maximal activity mediated by the unsumoylated form. In sum, this report introduces Brightlike as an additional functional member of the family of ARID proteins, which should be considered in regulatory circuits, previously ascribed to be mediated by Bright.

By using fractal model, this paper studied the fractal dimension of soil aggregate structure (D) in the slope farmland (CK), its 5-year de-farmed Neosinocalamus affinis plantation (NAP), Bambusa pervariabilis x Dendrocalamopsis oldhami plantation (BDP), Alnus crenastogyne + Neosinocalamus affinis plantation (ANP), and abandoned farmland (AFL) in south Sichuan Province of China, and analyzed the relationships between the D and soil physical and chemical properties. In the de-farmed plantations and abandoned farmland, the contents of > 0.25 mm soil aggregates and water-stable aggregates were increased significantly, compared with those in the slope farmland. The D was 1.377-2.826, being in the order of NAP < BDP < ANP < AFL < CK, and decreased with the increasing contents of > 0.25 mm soil aggregates and water-stable aggregates. Comparing with CK, de-farming increased the soil natural water content, capillary porosity, and contents of soil organic matter, total N, alkali-hydrolysable N, total P, and total K, and decreased soil bulk density, non-capillary porosity, and aeration porosity. There were close relationships between the fractal dimension of soil aggregate structure and the soil physical and chemical properties. All the results suggested that the de-farming of slope farmland was beneficial to the increase of the contents of > 0.25 mm soil aggregates and water-stable aggregates, and the enhancement of soil structure stability. The D could be used as an ideal index to evaluate soil fertility, and planting Neosinocalamus affinis on the de-farming slope farmland was a good measure for the improvement of soil fertility in the research area.

With different polarity responses, coumarin and 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) were hybridised to construct polarity fluorescent sensors, CBDP and iso-CBDP, to overcome the disadvantages of solvatochromic sensors in ratiometric polarity sensing. Only CBDP displayed an emission ratio (I Cou /I BDP , coumarin to BODIPY emissions) that increased with an exponential dependence on medium relative permittivity over a wide polarity range (ϵ r <57.9). This sensing ability of CBDP was not affected by medium pH; viscosity; and most intracellular species, especially reactive oxygen, nitrogen, and sulfur species. Apart from local cytoplasmic polarity quantification through lambda imaging, CBDP enables real-time ratiometric imaging for intracellular polarity oscillation induced by oxidative stimulation. Ratiometric polarity flow cytometry was developed, for the first time, with CBDP, which demonstrated that a high concentration H 2 O 2 induced cytoplasmic polarity enhancement, whereas pre-incubation with N-acetyl-l-cysteine inhibited this effect. © 2018 Wiley-VCH Verlag GmbH & Co.

Abstract Background: Electroencephalographic (EEG) studies of the visual steady-state response (ssVEP) probe the oscillatory capacity and synchronization in the primary visual cortex. Previous ssVEP studies have demonstrated early visual processing deficits in schizophrenia (SZ). However, few studies have examined the ssVEP across diagnostic categories and included the full spectrum of psychotic subgroups (schizophrenia: SZ, schizoaffective disorder: SAD, bipolar disorder with psychosis: BDP, and bipolar disorder without psychosis: BD-NP). This is a critical step in order to investigate its potential as a biomarker and to examine specific neural deficits that are unique to each disorder. In this study visual steady-state stimuli in the central, bilateral, left, and right hemisphere were administered to a large sample of well characterized participants diagnosed with SZ, SAD, BDP, or BD-NP. Methods: Four hundred and seven individuals (HC = 153, SZ = 64, SAD = 79, BDP = 65, BD-NP = 46) completed the ssVEP EEG task at the 5 BSNIP sites. A black and white square oscillating at 18.75 Hz was placed in the subject’s central, bilateral, left, and right visual field for 2000 ms. Inter-trial phase coherence (ITC) was calculated for each subject, sensor, and task. The resulting time-frequency values ranged from 4 to 53 Hz and −500 to 2000 ms poststimulus. The 7 peak sensors from the grand average for each task were selected and used to average over the 0–2000 ms ssVEP period for each subject. One-way ANOVA’s and Welch’s t tests were conducted to determine group differences for each task. Results: SAD had significantly reduced ITC in comparison to HC during the bilateral ssVEP task. SZ and SAD both had significantly reduced ITC in comparison to HC and BD-NP during the center visual field trials. There were no significant group differences in either left or right visual field trials for any of the groups. BDP and BD-NP did not differ from HC in any of the conditions. Conclusion: There are 2 main conclusions that can be drawn from this study. (1) Both SZ and SAD had a reduced response to the central stimuli. This is suggestive of a core deficit at the beginning of the visual processing pathway. (2) SAD had a reduction in response the bilateral stimuli. This suggests that SAD has a unique deficit in interhemispheric visual response that is not found in any of the other psychotic or bipolar disorders. Examining differences in the ssVEP between proband groups offers unique insight into how neural synchronization relates to the etiology of SZ and SAD. This provides novel information about core visual processing deficits that could potentially be used as a translational biomarker.

The Adverse Outcome Pathway (AOP) framework represents a valuable conceptual tool to systematically integrate existing toxicological knowledge from a mechanistic perspective to facilitate predictions of chemical-induced effects across species. However, its application for decision-making requires the transition from qualitative to quantitative AOP (qAOP). Here we used a fish model and the synthetic glucocorticoid beclomethasone dipropionate (BDP) to investigate the role of chemical-specific properties, pharmacokinetics, and internal exposure dynamics in the development of qAOPs. We generated a qAOP network based on drug plasma concentrations and focused on immunodepression, skin androgenisation, disruption of gluconeogenesis and reproductive performance. We showed that internal exposure dynamics and chemical-specific properties influence the development of qAOPs and their predictive power. Comparing the effects of two different glucocorticoids, we highlight how relatively similar in vitro hazard-based indicators can lead to different in vivo risk. This discrepancy can be predicted by their different uptake potential, pharmacokinetic (PK) and pharmacodynamic (PD) profiles. We recommend that the development phase of qAOPs should include the application of species-species uptake and physiologically-based PK/PD models. This integration will significantly enhance the predictive power, enabling a more accurate assessment of the risk and the reliable transferability of qAOPs across chemicals.

In recent years, the computer networking community has seen a steady growth in bandwidth-delay products (BDPs). Several TCP variants were created to combat the shortcomings of legacy TCP when it comes to operation in high-BDP environments. These variants, among which are CUBIC, STCP, and H-TCP, have been extensively studied in some empirical contexts, and some analytical models exist for CUBIC and STCP. However, since these studies have been conducted, BDPs have risen even more, and new bulk data transfer tools have emerged that utilize multiple parallel TCP streams. In view of these new developments, it is imperative to revisit themore » question: Which congestion control algorithms are best adapted to current networking environments? In order to help resolve this question, we contribute the following: (i) using first principles, we develop a general throughput-prediction framework that takes into account buffer sizes and maximum window constraints; (ii) we validate the models using measurements and achieve low prediction errors; (iii) we note differences in TCP dynamics between two experimental configurations and find one of them to be significantly more deterministic than the other; we also find that CUBIC and H-TCP outperform STCP, especially when multiple streams are used; and (iv) we present preliminary results for modelling multiple TCP streams for CUBIC and STCP.« less

Glucosinolates (GLSs) are found in Brassica vegetables. Examples of these sources include cabbage, Brussels sprouts, broccoli, cauliflower and various root vegetables (e.g. radish and turnip). A number of epidemiological studies have identified an inverse association between consumption of these vegetables and the risk of colon and rectal cancer. Animal studies have shown changes in enzyme activities and DNA damage resulting from consumption of Brassica vegetables or isothiocyanates, the breakdown products (BDP) of GLSs in the body. Mechanistic studies have begun to identify the ways in which the compounds may exert their protective action but the relevance of these studies to protective effects in the human alimentary tract is as yet unproven. In vitro studies with a number of specific isothiocyanates have suggested mechanisms that might be the basis of their chemoprotective effects. The concentration and composition of the GLSs in different plants, but also within a plant (e.g. in the seeds, roots or leaves), can vary greatly and also changes during plant development. Furthermore, the effects of various factors in the supply chain of Brassica vegetables including breeding, cultivation, storage and processing on intake and bioavailability of GLSs are extensively discussed in this paper.

During the aerosol delivery device design and optimization process, in vitro lung dose (LD) measurements are often performed using soft face models, which may provide a more clinically relevant representation of face mask dead volume (MDV) and face mask seal (FMS) than hard face models. However, a comparison of MDV, FMS, and LD for hard and soft face models is lacking. Metal, silicone, and polyurethane represented hard, soft, and very soft facial materials, respectively. MDV was measured using a water displacement technique. FMS was measured using a valved holding chamber (VHC) flow rate technique. The LD of beclomethasone dipropionate (BDP) delivered via a 100-μg Qvar® pressurized metered dose inhaler with AeroChamber Plus® Flow-Vu® VHC and Small Mask, defined as that which passes through the nasal airways of the idealized infant geometry, was measured using a bias tidal flow system with a filter. MDV, FMS, and LD were measured at 1.5 lb and 3.5 lb of applied force. A mathematical model was used to predict LD based on experimental measurements of MDV and FMS. Experimental BDP LD measurements for ABS, silicone, and polyurethane at 1.5 lb were 0.9 (0.6) μg, 2.4 (1.9) μg, and 19.3 (0.9) μg, respectively. At 3.5 lb, the respective LD was 10.0 (1.5) μg, 13.8 (1.4) μg, and 14.2 (0.9) μg. Parametric analysis with the mathematical model showed that differences in FMS between face models had a greater impact on LD than differences in MDV. The use of soft face models resulted in higher LD than hard face models, with a greater difference at 1.5 lb than at 3.5 lb. A lack of a FMS led to decreased dose consistency; therefore, a sealant should be used when measuring LD with a hard ABS or soft silicone face model at 1.5 lb of applied force or less.

Vascular access infections are of concern to hemodialysis patients and nurses. Best demonstrated practices (BDPs) have not been developed for home hemodialysis (HHD) access use, but there have been generally accepted practices (GAPs) endorsed by dialysis professionals. We developed a survey to gather information about training provided and actual practices of HHD patients using the NxStage System One HHD machine. We used GAP to assess training used by nurses to teach HHD access care and then assess actual practice (adherence) by HHD patients. We also assessed training and adherence where GAPs do not exist. We received a 43% response rate from patients and 76% response from nurses representing 19 randomly selected HHD training centers. We found that nurses were not uniformly instructing HHD patients according to GAP, patients were not performing access cannulation according to GAP, nor were they adherent to their training procedures. Identification of signs and symptoms of infection was commonly trained appropriately, but we observed a reluctance to report some signs and symptoms of infection by patients. Of particular concern, when aggregating all steps surveyed, not a single nurse or patient reported training or performing all steps in accordance with GAP. We also identified practices for which there are no GAPs that require further study and may or may not impact outcomes such as infection. Further research is needed to develop strategies to implement and expand GAP, measure outcomes, and ultimately develop BDP for HHD to improve infectious complications. © 2014 The Authors.

Gadolinium ion (Gd(3+)) complexes are commonly used as magnetic resonance imaging (MRI) contrast agents to enhance signals in T(1)-weighted MR images. Recently, several methods to achieve cell-permeation of Gd(3+) complexes have been reported, but more general and efficient methodology is needed. In this report, we describe a novel method to achieve cell permeation of Gd(3+) complexes by using hydrophobic fluorescent dyes as a cell-permeability-enhancing unit. We synthesized Gd(3+) complexes conjugated with boron dipyrromethene (BDP-Gd) and Cy7 dye (Cy7-Gd), and showed that these conjugates can be introduced efficiently into cells. To examine the relationship between cell permeability and dye structure, we further synthesized a series of Cy7-Gd derivatives. On the basis of MR imaging, flow cytometry, and ICP-MS analysis of cells loaded with Cy7-Gd derivatives, highly hydrophobic and nonanionic dyes were effective for enhancing cell permeation of Gd(3+) complexes. Furthermore, the behavior of these Cy7-Gd derivatives was examined in mice. Thus, conjugation of hydrophobic fluorescent dyes appears to be an effective approach to improve the cell permeability of Gd(3+) complexes, and should be applicable for further development of Gd(3+)-based MRI contrast agents.

Background Hirschsprung disease (HSCR) is a heterogeneous genetic disorder characterized by absence of ganglion cells along intestines resulting in functional bowel obstruction. NRG1 gene has been implicated in the intestinal ganglionosis. This study aimed to investigate the contribution of NRG1 gene into the HSCR development in Indonesian population. Methods We performed Sanger sequencing to find NRG1 variants in 54 HSCR patients. Results All patients were sporadic non-syndromic HSCR with 53/54 (98%) and 1/54 (2%) were short-segment and long-segment patients, respectively. NRG1 analysis showed one rare variant, c.397G > C (p.V133L), and three common variants, rs7834206, rs3735774, and rs75155858. The p.V133L was predicted to reside within in a region of high mammalian conservation, overlap with the promoter and enhancer histone marks of relevant tissues such as digestive and smooth muscle tissues and alter AP-4_2, BDP1_disc3, Egr-1_known1, Egr-1_known4, HEN1_2 transcription factor binding motifs. Furthermore, this variant was absent in 92 controls. Conclusions This study is the first report of NRG1 rare variant associated with HSCR patients in South-East Asian ancestry and adds insights into the NRG1 effect in the molecular pathogenesis of HSCR.

BODIPY fluorophores linked with an imidazo-phenanthroline donor at α and β positions have been synthesized. Intriguing intramolecular charge transfer phenomenon is observed in both the dyes which has been extensively investigated using UV-vis absorption, steady-state and time-resolved fluorescence measurements. H-bonding and intrinsic polarity of the solvents has modulated the absorption and emission bands of these fluorophores strongly causing significant increase in the Stokes shifts. In spite of having difference only in terms of the position of donor subunit, the photophysics of these dyes are not only significantly different from each other, but contradictory too. Interestingly, acidochromic studies revealed the shuttling mechanism between ICT and PET processes for BDP 2. Quantum chemical calculations have been employed further to support experimental findings. DFT and TD-DFT method of analysis have been used to optimize ground and excited state geometries of the synthesized dyes.

The VLA Sky Survey (VLASS) is a 5520 hour spectropolarimetric synoptic survey covering the 33885 square degrees of the sky above Declination -40 degrees from 2-4 GHz at 2.5" angular resolution using the upgraded Karl G. Jansky Very Large Array (VLA). Over the survey duration of 7 years, each area of the sky will be covered in 3 epochs spaced 32 months apart, to a projected depth of 0.12mJy/beam rms noise per epoch and 0.07mJy/beam for 3 epochs combined. The VLASS employs on-the-fly mosaicking (OTFM) to rapidly scan the sky with a net speed of approximately 20 sq. degrees per hour. The high-level science goals for the survey include the identification and precise location of radio transients, the measurement of magnetic fields in our galaxy and beyond, and the study of radio emission from galaxies and active galactic nuclei throughout the Universe. The ability of the VLASS to see through dust allows us to unveil phenomena such as hidden cosmic explosions, emission from deep within our galaxy, and supermassive black holes buried within host galaxies.The VLASS was proposed in 2014 by our community-led Survey Science Group (SSG). VLASS Pilot observations were taken in mid-2016, and the first epoch covering half the area (VLASS1.1) commenced in September 2017. The raw data from the VLASS are available in the NRAO archive immediately with no proprietary period. The Basic Data Products (BDP) that will be produced by the survey team are public and will additionally include: calibrated visibility data, quick-look continuum images (with a goal of posting to the archive within 1 week of observation), single-epoch and cumulative combined-epoch images, spectral image cubes, and basic object catalogs. Single-epoch and cumulative images are in intensity and linear polarization (Stokes IQU). In addition to the BDP provided by NRAO and served through the NRAO archive, there are plans for Enhanced Data Products and Services to be provided by the community in partnership with the VLASS team.In this presentation we describe the science goals, survey design, and technical implementation for the VLASS, and highlight results from the Pilot and the first epoch observations taken so far.

RNA polymerase III (Pol III) synthesizes tRNAs and other small noncoding RNAs to regulate protein synthesis. Dysregulation of Pol III transcription has been linked to cancer, and germline mutations in genes encoding Pol III subunits or tRNA processing factors cause neurogenetic disorders in humans, such as hypomyelinating leukodystrophies and pontocerebellar hypoplasia. Here we describe an autosomal recessive disorder characterized by cerebellar hypoplasia and intellectual disability, as well as facial dysmorphic features, short stature, microcephaly, and dental anomalies. Whole-exome sequencing revealed biallelic missense alterations of BRF1 in three families. In support of the pathogenic potential of the discovered alleles, suppression or CRISPR-mediated deletion of brf1 in zebrafish embryos recapitulated key neurodevelopmental phenotypes; in vivo complementation showed all four candidate mutations to be pathogenic in an apparent isoform-specific context. BRF1 associates with BDP1 and TBP to form the transcription factor IIIB (TFIIIB), which recruits Pol III to target genes. We show that disease-causing mutations reduce Brf1 occupancy at tRNA target genes in Saccharomyces cerevisiae and impair cell growth. Moreover, BRF1 mutations reduce Pol III–related transcription activity in vitro. Taken together, our data show that BRF1 mutations that reduce protein activity cause neurodevelopmental anomalies, suggesting that BRF1-mediated Pol III transcription is required for normal cerebellar and cognitive development.

While emotional difficulties are highly implicated in borderline personality disorder (BPD), the dynamic relationships between emotions and BPD symptoms that occur in everyday life are unknown. The current paper examined the function of negative emotions as they relate to BPD symptoms in real time. Experience sampling methodology with 281 participants measured negative emotions and borderline symptoms, expressed as a spectrum of experiences, five times daily for two weeks. Overall, having a BDP diagnosis was associated with experiencing more negative emotions. Multilevel modeling supported positive concurrent relationships between negative emotions and BPD symptoms. Lagged models showed that even after three hours negative emotions and several symptoms continued to influence each other. Therefore, results indicated that negative emotions and BPD symptoms are intricately related; some evidenced long-lasting relationships. This research supports emotion-symptom contingencies within BPD and provides insight regarding the reactivity and functionality of negative emotions in borderline pathology. PMID:25710731

Highly porous nanocellulose aerogels prepared by freeze-drying from various nanofibrillar cellulose (NFC) hydrogels are introduced as nanoparticle reservoirs for oral drug delivery systems. Here we show that beclomethasone dipropionate (BDP) nanoparticles coated with amphiphilic hydrophobin proteins can be well integrated into the NFC aerogels. NFCs from four different origins are introduced and compared to microcrystalline cellulose (MCC). The nanocellulose aerogel scaffolds made from red pepper (RC) and MCC release the drug immediately, while bacterial cellulose (BC), quince seed (QC) and TEMPO-oxidized birch cellulose-based (TC) aerogels show sustained drug release. Since the release of the drug is controlled by the structure and interactions between the nanoparticles and the cellulose matrix, modulation of the matrix formers enable a control of the drug release rate. These nanocomposite structures can be very useful in many pharmaceutical nanoparticle applications and open up new possibilities as carriers for controlled drug delivery.

Biogenic silica contents of sediments on the lower Selenga Delta and Buguldeika saddle in Lake Baikal show distinct fluctuations that reflect changes in diatom productivity, and ultimately, climate. The pattern of the upper 50 m of the section, dating from about 334 ka, is similar to that of the marine oxygen-isotope record, increasingly so as the younger sediments become progressively finer grained and less locally derived with time. The last two interglaciations are marked by biogenic silica abundances similar to those of the Holocene. The equivalent of marine oxygen-isotope stage 3 is distinctly intermediate in character between full glacial and full interglacial biogenic silica values. Following near-zero values during the last glacial maximum, biogenic silica began to increase at about 13 ka. The rise in biogenic silica to Holocene values was interrupted by an abrupt decrease during Younger Dryas time, about 11 to 10 14C ka.

The thermomagnetic and microprobe analyses were done for sedimentary samples from the highland Darhad Basin located in northern Mongolia; from the southwest of the Baikal Rift Zone and sedimentary samples from DSDP 386, 387, 391A, and 391C boreholes in the northwestern Atlantic; sediments from the lower section of the borehole BDP-98 drilled at the bottom on the Akademichesky Ridge of Lake Baikal. All sediment has different sedimentation rates from 1-2 cm/kyr to 47 m/myr. The thermomagnetic analysis (TMA) measurements were made using the Curie express balance, constructed by Burov et.al. The TMA included measuring the specific magnetization of the samples in the magnetic field up to 500 mT at room temperature and recording the temperature dependence of magnetization. The heating rate is 100°C/min. The resulting thermomagnetic curves were used for identifying the Curie points of the magnetic minerals present in the sample and for establishing the character of the heating related mineral alterations, which can often be treated as the diagnostic signs of certain minerals. More interesting particles for us - native iron are identified from Curie points Tc = 710-770 °C. For some samples which contain minerals with the temperatures higher than 710 °C were made magnetic extraction. Magnetic extracts investigated on electron microscope. This analysis have done for determine the origin (cosmic or terrestrial) of native iron. The concentrations of native iron are bimodal everywhere with the zero mode necessarily present it testifies to the predominantly cosmic origin of the native iron. It is shown that quantity of cosmic dust depends on sedimentation rate and if it is slow, we have more particles if the speed is high more difficult to determine native iron. The work was carried out according to the Russian Government's Program of Competitive Growth of Kazan Federal University, supported by the grant provided to the Kazan State University for performing the state program in the field of scientific research, and partially supported by the Russian Foundation for Basic research №14-05-31376.

Progress in understanding protein folding relies heavily upon an interplay between experiment and theory. In particular, readily interpretable experimental data are required that can be meaningfully compared to simulations. According to standard mutational φ analysis, the transition state for Protein L contains only a single hairpin. However, we demonstrate here using ψ analysis with engineered metal ion binding sites that the transition state is extensive, containing the entire four-stranded β sheet. Underreporting of the structural content of the transition state by φ analysis also occurs for acyl phosphatase1, ubiquitin2 and BdpA3. The carboxy terminal hairpin in the transition state of Protein L is found to be non-native, a significant result that agrees with our PDB-based backbone sampling and all-atom simulations. The non-native character partially explains the failure of accepted experimental and native-centric computational approaches to adequately describe the transition state. Hence, caution is required even when an apparent agreement exists between experiment and theory, thus highlighting the importance of having alternative methods for characterizing transition states.

3,5-Diformyl-4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (3,5-diformyl-BODIPY) can be used as an efficient biofunctional cross-linker to generate a new class of chitosan-based hydrogels with fluorescence resonance energy transfer (FRET) dynamics and good solubility in water. The hydrogel was fully characterized by FT-IR, UV-vis, fluorescence, FE-SEM, AFM, rheology and picosecond time-resolved spectroscopic techniques. The self-healing ability was demonstrated by rheological recovery and macroscopic and microscopic observations. The fluorescence lifetime was found to increase in aqueous solution of the BODIPY-chitosan hydrogel compared to the 3,5-diformyl-BODIPY monomer. Calculations based on experimental results such as red-shift and decreased intensity of the emission spectrum of highly dye-concentrated hydrogel in comparison to dilute hydrogels, together with changes in the fluorescence lifetime of the hydrogel at different concentration of dyes, suggest that the BDP-CS hydrogels fluorescence dynamics obey the Förster resonance energy transfer (FRET). Improvements in mechanical and photochemical properties and the acceptable values of BODIPY fluorescence lifetime in the hydrogel matrix indicate the utility of the newly synthesized hydrogels for biomedical applications.

To evaluate the effect of fetal sex on singleton pregnancy growth charts customized for parental characteristics, race, and parity Methods: In a multicentric cross-sectional study, 8070 ultrasonographic examinations from low-risk singleton pregnancies between 16 and 40 weeks of gestation were considered. The fetal measurements obtained were biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL). Quantile regression was used to examine the impact of fetal sex across the biometric percentiles of the fetal measurements considered together with parents' height, weight, parity, and race. Fetal gender resulted to be a significant covariate for BDP, HC, and AC with higher values for male fetuses (p ≤ 0.0009). Minimal differences were found among sexes for FL. Parity, maternal race, paternal height and maternal height, and weight resulted significantly related to the fetal biometric parameters considered independently from fetal gender. In this study, we constructed customized biometric growth charts for fetal sex, parental, and obstetrical characteristics using quantile regression. The use of gender-specific charts offers the advantage to define individualized normal ranges of fetal biometric parameters at each specific centile. This approach may improve the antenatal identification of abnormal fetal growth.

Identifying effective internal factors for regulating germline commitment during development and for maintaining spermatogonial stem cells (SSCs) self-renewal is important to understand the molecular basis of spermatogenesis process, and to develop new protocols for the production of the germline cells from other cell sources. Therefore, this study was designed to investigate single-cell RNA-sequencing data for identification of differentially expressed genes (DEGs) in 12 mouse-derived single SSCs (mSSCs) in compare with 16 mouse-derived single mesenchymal stem cells. We also aimed to find transcriptional regulators of DEGs. Collectively, 1,584 up-regulated DEGs were identified that are associated with 32 biological processes. Moreover, investigation of the expression profiles of genes including in spermatogenesis process revealed that Dazl, Ddx4, Sall4, Fkbp6, Tex15, Tex19.1, Rnf17, Piwil2, Taf7l, Zbtb16, and Cadm1 are presented in the first 30 up-regulated DEGs. We also found 12 basal transcription factors (TFs) and three sequence-specific TFs that control the expression of DEGs. Our findings also indicated that MEIS1, SMC3, TAF1, KAT2A, STAT3, GTF3C2, SIN3A, BDP1, PHC1, and EGR1 are the main central regulators of DEGs in mSSCs. In addition, we collectively detected two significant protein complexes in the protein-protein interactions network for DEGs regulators. Finally, this study introduces the major upstream kinases for the main central regulators of DEGs and the components of core protein complexes. In conclusion, this study provides a molecular blueprint to uncover the molecular mechanisms behind the biology of SSCs and offers a list of candidate factors for cell type conversion approaches and production of germ cells. © 2017 Wiley Periodicals, Inc.

How Do Stress Exposure and Stress Regulation Relate to Borderline Personality Disorder?

Borderline personality disorder (BPD) is a severe and frequent disorder characterized by a pervasive pattern of instability affecting impulse control, emotional regulation, cognitive processing, self-image and interpersonal relationships. Patients’ personal histories are often marked by stressful or traumatic experiences, either unique or repeated. Moreover, while clinical signs of the disorder include both chronic and acute features, acute features are mostly triggered by acute stressful situations. Such features include transient cognitive distortion, intense anger, uncontrollable impulsivity, and self-harm behavior – including suicide – and contribute to the burden of the disease. In this paper, we review the various aspects (epidemiological, clinical, and physiological) contributing to the relationship between BDP and stress. In particular, we explore the statistical association between stress exposure and the emergence of BPD while taking into account other psychopathologies, such as post-traumatic stress disorder. Then, the different aspects of stress responses (namely, the phenomenological, behavioral, hormonal, neuro-vegetative and neural responses) are reviewed in BPD patients. Pathophysiological hypotheses are formulated to explain the differences in responses between BPD patients and healthy subjects and their relation to BPD symptoms. Although the pathogenesis remains uncertain, our conclusions seem to reflect a specific biological and neural pattern of altered stress perception and regulation in BPD. PMID:29250007

We elaborate on a linear-time implementation of Collective-Influence (CI) algorithm introduced by Morone, Makse, Nature 524, 65 (2015) to find the minimal set of influencers in networks via optimal percolation. The computational complexity of CI is O(N log N) when removing nodes one-by-one, made possible through an appropriate data structure to process CI. We introduce two Belief-Propagation (BP) variants of CI that consider global optimization via message-passing: CI propagation (CIP) and Collective-Immunization-Belief-Propagation algorithm (CIBP) based on optimal immunization. Both identify a slightly smaller fraction of influencers than CI and, remarkably, reproduce the exact analytical optimal percolation threshold obtained in Random Struct. Alg. 21, 397 (2002) for cubic random regular graphs, leaving little room for improvement for random graphs. However, the small augmented performance comes at the expense of increasing running time to O(N2), rendering BP prohibitive for modern-day big-data. For instance, for big-data social networks of 200 million users (e.g., Twitter users sending 500 million tweets/day), CI finds influencers in 2.5 hours on a single CPU, while all BP algorithms (CIP, CIBP and BDP) would take more than 3,000 years to accomplish the same task.

Facile and High-Throughput Synthesis of Functional Microparticles with Quick Response Codes.

2016-06-01

Encoded microparticles are high demand in multiplexed assays and labeling. However, the current methods for the synthesis and coding of microparticles either lack robustness and reliability, or possess limited coding capacity. Here, a massive coding of dissociated elements (MiCODE) technology based on innovation of a chemically reactive off-stoichimetry thiol-allyl photocurable polymer and standard lithography to produce a large number of quick response (QR) code microparticles is introduced. The coding process is performed by photobleaching the QR code patterns on microparticles when fluorophores are incorporated into the prepolymer formulation. The fabricated encoded microparticles can be released from a substrate without changing their features. Excess thiol functionality on the microparticle surface allows for grafting of amine groups and further DNA probes. A multiplexed assay is demonstrated using the DNA-grafted QR code microparticles. The MiCODE technology is further characterized by showing the incorporation of BODIPY-maleimide (BDP-M) and Nile Red fluorophores for coding and the use of microcontact printing for immobilizing DNA probes on microparticle surfaces. This versatile technology leverages mature lithography facilities for fabrication and thus is amenable to scale-up in the future, with potential applications in bioassays and in labeling consumer products. © 2016 WILEY-VCH Verlag GmbH & Co.

Quantifying the structural requirements of the folding transition state of Protein A and other systems

The B-domain of protein A (BdpA) is a small 3-helix bundle that has been the subject of considerable experimental and theoretical investigation. Nevertheless, a unified view of the structure of the transition state ensemble (TSE) is still lacking. To characterize the TSE of this surprisingly challenging protein, we apply a combination of ψ-analysis (which probes the role of specific side chain to side chain contacts) and kinetic H/D amide isotope effects (which measures of hydrogen bond content), building upon previous studies using mutational φ-analysis (which probes the energetic influence of side chain substitutions). The second helix (H2) is folded in the TSE, while helix formation appears just at the carboxy and amino termini of the first and third helices, respectively. The experimental data suggest a homogenous, yet plastic TS with a native-like topology. This study generalizes our earlier conclusion, based on two larger α/β proteins, that the TSEs of most small proteins achieve ~70% of their native state’s relative contact order. This high percentage limits the degree of possible TS heterogeneity and requires a re-evaluation of the structural content of the TSE of other proteins, especially when they are characterized as small or polarized.

We detected the longitudinal variability of phosphorus speciations and its relation to metals and grain size distribution of sediments in three cascade canyon reservoirs (Xiaowan, Manwan and Dachaoshan) along Lancang River, China. Five phosphorus speciations including loosely bound P (ex-P), reductant soluble P (BD-P), metal oxide-bound P (NaOH-P) calcium-bound P (HCl-P) and residual-P were extracted and quantified. Results showed that in Manwan Reservoir HCl-P accounted for the largest part of total phosphorus (TP) (49.69%), while in Xiaowan and Dachaoshan reservoirs, NaOH-P was the most abundant speciation which accounted for 57.21% and 55.19% of total phosphorus respectively. Higher contents of bio-available phosphorus in Xiaowan and Dachaoshan reservoirs suggested a high rate of P releasing from sediments. Results also showed ex-P and HCl-P had positive correlation with Ca. Total phosphorus was positively correlated with Fe. The silt/clay contents of the sediments had close relationship with ex-P (r=0.413, p<0.05), NaOH-P (r=0.428, p<0.05) and BAP (r=0.458, p<0.05). The concentration of Ca, Mn and silt/clay speciation in the sediments explained 40%, 10% and 4% of the spatial variation of phosphorus speciations, respectively. Copyright © 2014 Elsevier Ltd.

Impaired growth and neurological abnormalities in branched-chain α-keto acid dehydrogenase kinase-deficient mice

The BCKDH (branched-chain α-keto acid dehydrogenase complex) catalyses the rate-limiting step in the oxidation of BCAAs (branched-chain amino acids). Activity of the complex is regulated by a specific kinase, BDK (BCKDH kinase), which causes inactivation, and a phosphatase, BDP (BCKDH phosphatase), which causes activation. In the present study, the effect of the disruption of the BDK gene on growth and development of mice was investigated. BCKDH activity was much greater in most tissues of BDK−/− mice. This occurred in part because the E1 component of the complex cannot be phosphorylated due to the absence of BDK and also because greater than normal amounts of the E1 component were present in tissues of BDK−/− mice. Lack of control of BCKDH activity resulted in markedly lower blood and tissue levels of the BCAAs in BDK−/− mice. At 12 weeks of age, BDK−/− mice were 15% smaller than wild-type mice and their fur lacked normal lustre. Brain, muscle and adipose tissue weights were reduced, whereas weights of the liver and kidney were greater. Neurological abnormalities were apparent by hind limb flexion throughout life and epileptic seizures after 6–7 months of age. Inhibition of protein synthesis in the brain due to hyperphosphorylation of eIF2α (eukaryotic translation initiation factor 2α) might contribute to the neurological abnormalities seen in BDK−/− mice. BDK−/− mice show significant improvement in growth and appearance when fed a high protein diet, suggesting that higher amounts of dietary BCAA can partially compensate for increased oxidation in BDK−/− mice. Disruption of the BDK gene establishes that regulation of BCKDH by phosphorylation is critically important for the regulation of oxidative disposal of BCAAs. The phenotype of the BDK−/− mice demonstrates the importance of tight regulation of oxidative disposal of BCAAs for normal growth and neurological function. PMID:16875466

To study the efficacy of different preparations of budesonide combined with pulmonary surfactant (PS) in improving blood gas levels and preventing bronchopulmonary dysplasia (BPD) in preterm infants with neonatal respiratory distress syndrome (NRDS). A total of 184 preterm infants who developed NRDS within 4 hours after birth were randomly administered with PS + continuous inhalation of budesonide aerosol (continuous aerosol group), PS+budesonide solution (solution group), PS + single inhalation of budesonide aerosol (single aerosol group), and PS alone, with 46 neonates in each group. The changes in arterial blood gas levels, rate of invasive mechanical ventilation after treatment, time of assisted ventilation, rate of repeated use of PS, and the incidence of BPD were compared between the four groups. On the 2nd to 4th day after treatment, pH, PCO2, and oxygenation index (FiO2/PaO2) showed significant differences among the four groups, and the continuous aerosol group showed the most improvements of all indicators, followed by the solution group, single aerosol group, and PS alone group. The continuous aerosol group had a significantly shorter time of assisted ventilation than the other three groups (P<0.05). The solution group had a significantly shorter time of assisted ventilation than the single aerosol and PS alone groups (P<0.05). The rate of invasive mechanical ventilation after treatment, rate of repeated use of PS, and incidence of BPD showed significant differences among the four groups (P<0.05), and the continuous aerosol group had the lowest rates, followed by the solution group. A combination of PS and continuous inhalation of budesonide aerosol has a better efficacy in the treatment of NRDS than a combination of PS and budesonide solution. The difference in reducing the incidence of BDP between the two administration methods awaits further investigation with a larger sample size.

DGT (diffusive gradients in thin films) technique and DIFS (DGT induced fluxes in sediment) model are firstly designed for macrophyte-rhizobox system and in-situ macrophytes in Lake Erhai. Dynamics of phosphorus (P) transfer in Zizania latifolia (ZL) and Myriophyllum verticiilatur (MV) rhizosphere is revealed and phytoremediation performance for P in sediment is evaluated. Dynamic transfer process of P at DGT/sediment interface includes (i) diffusion flux and concentration gradients at DGT(root)/porewater interface leading to porewater concentration (C 0 ) depletion and (ii) P desorption from labile P pool in sediment solid to resupply C 0 depletion. Fe-redox controlled P release from Fe-bound P (BD-P2) and then NH 4 Cl-P1 in rhizosphere sediment resupplies porewater depletion due to DGT (root) sink. K d (labile P pool size in solid phase), r (resupply ratio) and kinetic exchange (Tc and k -1 ) lead to change characters of DIFS curves of (1) r against deployment time and (2) C solu (dissolved concentration) against distance at 24 h. They include two opposite types of "fast" and "slow" rate of resupplies. Sediment properties and DIFS parameters control P diffusion and resupply in rhizosphere sediment. Phytoremoval ability for sediment P in lake is estimated to be 23.4 (ZL) or 15.0 t a -1 (MV) by "DGT-flux" method. Copyright © 2018 Elsevier B.V. All rights reserved.

The extensive use of reclaimed wastewater (RW) as a source of urban landscape pond replenishment, stimulated by the lack of surface water (SW) resources, has raised public concern. Greater attention should be paid to pond sediments, which act as 'sinks' and 'sources' of contaminants to the overlying pond water. Three ponds replenished with RW (RW ponds) in three Chinese cities were chosen to investigate 22 indices of sediment quality in four categories: eutrophication, heavy metal, ecotoxicity and pathogens risk. RW ponds were compared with other ponds of similar characteristics in the same cities that were replenished with SW (SW ponds). Our results show a strong impact of RW to the eutrophication and pathogenic risks, which are represented by organic matter, water content, total nitrogen, total phosphorus and phosphorus fractions, and pathogens. In particular, total phosphorus concentrations in the RW pond sediments were, on average, 50% higher than those of SW ponds. Moreover, the content of phosphorus, extracted by bicarbonate/dithionite (normally represented by BD-P) and NaOH (NaOH-P), were 2.0- and 2.83-times higher in RW ponds, respectively. For pathogens, the concentrations of norovirus and rotavirus in RW pond sediments were, on average, 0.52 and 0.30- log times those of SW ponds. The duration of RW replenishment was proved to have a marked impact on the eutrophication and pathogens risks from sediments. The continued use of RW for replenishment increases the eutrophication risk, and the pathogens risk, especially by viral pathogens, becomes greater. Copyright © 2018 Elsevier Ltd.

Identification of patients with a bipolar disorder (BPD) among those presenting a major depressive episode is often difficult, resulting in common misdiagnosis and mistreatment. Our aim was to identify clinical variables unrelated to current depressive episode and relevant to suicidal behavior that may help to improve the detection of BPD in suicide attempters presenting with recurrent major depressive disorder. 211 patients suffering from recurrent major depressive disorder or BPD, hospitalized after a suicide attempt (SA), were interviewed by semi-structured interview and validated questionnaires about DSM-IV axis I disorders, SA characteristics and a wide range of personality traits relevant to suicidal vulnerability. Multivariate logistic regression analysis was performed to determine differences between RMDD and BPD attempters. Logistic regression analysis showed that serious SA and family history of suicide are closely associated with a diagnosis of BPD [respectively OR=2.28, p=0.0195; OR=2.98, p=0.0081]. The presence of both characteristics increase the association with BDP [OR=4.78, p=0.005]. Conversely, when looking for the features associated with a serious SA, BPD was the only associated diagnosis [OR=2.03, p=0.004]. Lastly, affect intensity was higher in BPD samples [OR=2.08, p=0.041]. Retrospective nature of the study, lack of the separate analysis of bipolar subtypes. Serious suicide attempt and a familial history of completed suicide in patients with major depression seem to be a clinical marker of bipolarity. Facing suicide attempters with recurrent depression, clinician should be awareness to these characteristics to detect BPD. Copyright 2009 Elsevier B.V. All rights reserved.

A membrane glucocorticoid receptor mediates the rapid/non-genomic actions of glucocorticoids in mammalian skeletal muscle fibres

Glucocorticoids (GCs) are steroid hormones released from the adrenal gland in response to stress. They are also some of the most potent anti-inflammatory and immunosuppressive drugs currently in clinical use. They exert most of their physiological and pharmacological actions through the classical/genomic pathway. However, they also have rapid/non-genomic actions whose physiological and pharmacological functions are still poorly understood. Therefore, the primary aim of this study was to investigate the rapid/non-genomic effects of two widely prescribed glucocorticoids, beclomethasone dipropionate (BDP) and prednisolone acetate (PDNA), on force production in isolated, intact, mouse skeletal muscle fibre bundles. The results show that the effects of both GCs on maximum isometric force (Po) were fibre-type dependent. Thus, they increased Po in the slow-twitch fibre bundles without significantly affecting that of the fast-twitch fibre bundles. The increase in Po occurred within 10 min and was insensitive to the transcriptional inhibitor actinomycin D. Also, it was maximal at ∼250 nm and was blocked by the glucocorticoid receptor (GCR) inhibitor RU486 and a monoclonal anti-GCR, suggesting that it was mediated by a membrane (m) GCR. Both muscle fibre types expressed a cytosolic GCR. However, a mGCR was present only in the slow-twitch fibres. The receptor was more abundant in oxidative than in glycolytic fibres and was confined mainly to the periphery of the fibres where it co-localised with laminin. From these findings we conclude that the rapid/non-genomic actions of GCs are mediated by a mGCR and that they are physiologically/therapeutically beneficial, especially in slow-twitch muscle fibres.

Combined Fe/P and Fe/S ratios as a practicable index for estimating the release potential of internal-P in freshwater sediment.

Release of phosphorus (P) from sediment is a major source of P in many freshwater lakes. Currently, assessing the ability of sediment to release P, which is valuable to the management of water eutrophication, remains a challenge. Thus, the purpose of this study was to find effective indexes for predicting the release potential of internal-P. In this study, high-resolution diffusive gradients in thin films (DGT) and conventional sequential extraction were used to characterize the distribution and speciation of P, iron (Fe), and sulfur (S) in the surface sediment of a mildly eutrophic reservoir in southwestern China. Sediment samples exhibited large variations in Fe, S, and P, thereby providing favorable conditions for investigating the effects of Fe and S on sediment P mobilization. In contrast to traditional knowledge, our results show that total P (TP) and redox-sensitive P(BD-P) are poorly correlated with releasable P(DGT-P). This implies that high levels of sedimentary TP and BD-P do not necessarily result in an elevated release of internal-P under anaerobic conditions. Sedimentary P release was greatly suppressed at ratios of Fe/P > 30 and Fe/S > 6. Significant positive correlations between DGT-P and DGT-Fe or DGT-S suggest that Fe and S play an important role in governing the mobility of sedimentary P. These results support the combined Fe/P and Fe/S ratios as an effective and practicable index for assessing the ability of sediment to release P. Thus, our study provides a new and simple method for assessing sedimentary P pollution in freshwater ecosystems.

Estimation for general birth-death processes

Crawford, Forrest W.; Minin, Vladimir N.; Suchard, Marc A.

2013-01-01

Birth-death processes (BDPs) are continuous-time Markov chains that track the number of “particles” in a system over time. While widely used in population biology, genetics and ecology, statistical inference of the instantaneous particle birth and death rates remains largely limited to restrictive linear BDPs in which per-particle birth and death rates are constant. Researchers often observe the number of particles at discrete times, necessitating data augmentation procedures such as expectation-maximization (EM) to find maximum likelihood estimates. For BDPs on finite state-spaces, there are powerful matrix methods for computing the conditional expectations needed for the E-step of the EM algorithm. For BDPs on infinite state-spaces, closed-form solutions for the E-step are available for some linear models, but most previous work has resorted to time-consuming simulation. Remarkably, we show that the E-step conditional expectations can be expressed as convolutions of computable transition probabilities for any general BDP with arbitrary rates. This important observation, along with a convenient continued fraction representation of the Laplace transforms of the transition probabilities, allows for novel and efficient computation of the conditional expectations for all BDPs, eliminating the need for truncation of the state-space or costly simulation. We use this insight to derive EM algorithms that yield maximum likelihood estimation for general BDPs characterized by various rate models, including generalized linear models. We show that our Laplace convolution technique outperforms competing methods when they are available and demonstrate a technique to accelerate EM algorithm convergence. We validate our approach using synthetic data and then apply our methods to cancer cell growth and estimation of mutation parameters in microsatellite evolution. PMID:25328261

High blood pressure (HBP) is a modifiable cardiovascular risk factor and its detection at early ages may allow strategies to be designed to reduce cardiovascular risk in adulthood. To provide blood pressure (BP) values in a sample of adolescents using an electronic oscillometric device. BP was measured according the European Society of Hypertension guidelines using an oscillometric device. Height and weight were also measured. Four height groups were used in order to associate the 90, 95, and 99 percentiles with systolic BP (pSBP) and diastolic BP percentiles (pDBP) for sex and age: H150 (≤ 150cm), H160(151-160cm), H170(161-170cm), and H180(≥171cm). Data from 2,758 students aged 12-17 years were included in the analysis. BP increases with age, with differences of up to 11mmHg in boys vs. 3mmHg in girls for SBP and 3mmHg vs. 1mmHg for DBP. In high SBP, for the younger adolescents, the difference related to height was 15mmHg in boys vs. 8mmHg in girls, with no significant increase in the older ones in either gender. The high BDP varied depending on the height, 10mmHg in younger boys and 3mmHg in older ones, while in girls the variation was 3mmHg for all ages. SBP/DBP in adolescents increases with age and also with height, giving similar figures in the taller ones, regardless of age. Copyright © 2017 SEH-LELHA. Publicado por Elsevier España, S.L.U.

Nonlinear Insolation Forcing: A Physical Mechanism for Climate Change

NASA Technical Reports Server (NTRS)

Liu, H. S.

1998-01-01

This paper focuses on recent advances in the understanding of nonlinear insolation forcing for climate change. The amplitude-frequency resonances in the insolation variations induced by the Earth's changing obliquity are emergent and may provide a physical mechanism to drive the glaciation cycles. To establish the criterion that nonlinear insolation forcing is responsible for major climate changes, the cooperative phenomena between the frequency and amplitude of the insolation are defined as insolation pulsation. Coupling of the insolation frequency and amplitude variations has established an especially new and interesting series of insolation pulses. These pulses would modulate the insolation in such a way that the mode of insolation variations could be locked to generate the 100-kyr ice age cycle which is a long-time geophysical puzzle. The nonlinear behavior of insolation forcing is tested by energy balance and ice sheet climate models and the physical mechanism behind this forcing is explained in terms of pulse duration in the incoming solar radiation. Calculations of the solar energy flux at the top of the atmosphere show that the duration of the negative and positive insolation pulses is about 2 thousand years which is long enough to prolong glaciation into deep ice ages and cause rapid melting of large ice sheets in the high latitudes of the northern hemisphere. We have performed numerical simulations of climate response to nonlinear insolation forcing for the past 2 million years. Our calculated results of temperature fluctuations are in good agreement with the climate cycles as seen in the terrestrial biogenic silica (BDP-96-2) data as well as in the marine oxygen isotope (delta(sup 18)O) records.

Computational high-throughput screening was carried out to assess a large number of experimentally reported metal–organic frameworks (MOFs) and zeolites for their utility in hexane isomer separation. Through the paper, we identified many MOFs and zeolites with high selectivity (S L+M > 10) for the group of n-hexane, 2-methylpentane, and 3-methylpentane (linear and monobranched isomers) versus 2,2-dimethylbutane and 2,3-dimethylbutane (dibranched isomers). This group of selective sorbents includes VICDOC (Fe 2(BDP) 3), a MOF with triangular pores that is known to exhibit high isomer selectivity and capacity. For three of these structures, the adsorption isotherms for a 10-component mixture of hexane andmore » heptane isomers were calculated. Subsequent simulations of column breakthrough curves showed that the DEYVUA MOF exhibits a longer process cycle time than VICDOC MOF or MRE zeolite, which are previously reported, high-performing materials, illustrating the importance of capacity in designing MOFs for practical applications. Among the identified candidates, we synthesized and characterized a MOF in a new copper form with high predicted adsorbent capacity (q L+M > 1.2 mol/L) and moderately high selectivity (S L+M ≈ 10). In conclusion, we examined the role of pore shape in hexane isomer separations, especially of triangular-shaped pores. We show through the potential energy surface and three-dimensional siting analyses that linear alkanes do not populate the corners of narrow triangular channels and that structures with nontriangular pores can efficiently separate hexane isomers. Detailed thermodynamic analysis illustrates how differences in the free energy of adsorption contribute to shape-selective separation in nanoporous materials.« less

Improving Device Efficiencies in Organic Photovoltaics through the Manipulation of Device Architectures and the Development of Low-Bandgap Materials

NASA Astrophysics Data System (ADS)

Rice, Andrew Hideo

Over the past two decades, vast amounts of research have been conducted in the pursuit of suitable organic semiconductors to replace inorganic materials in electronic applications due to their advantages of being lightweight, flexible, and solution-processible. However, before organic photovoltaics (OPVs) can be truly competitive and commercially viable, their efficiencies must be improved significantly. In this examination, we pursue higher efficiency OPVs in two different ways. Our attempts focus on 1) altering the microstructure of devices to improve charge dissociation, charge transport, and our understanding of how these devices function, and 2) tailoring materials to achieve optimal band gaps and energy levels for use in organic electronics. First, we demonstrate how the vertical morphology of bulk heterojunction (BHJ) solar cells, with an active layer consisting of self-assembled poly(3-hexylthiophene) (P3HT) nanowires and (6,6)-phenyl C61-butyric acid methyl ester (PCBM), can be beneficially influenced. Most device fabrication routes using similar materials employ an annealing step to influence active layer morphology, but this process can create an unfavorable phase migration where P3HT is driven toward the cathode. In contrast, we demonstrate devices that exhibit an increase in relative fullerene concentration at the top of the active layer by introducing the donor phase as a solid nanowire in the active layer solution and altering the pre-spin drying time. X-ray photoelectron spectroscopy (XPS) and conductive and photoconductive atomic force microscopy (cAFM and pcAFM) provide detailed information about how the surface of the active layer can be influenced; this is done by tracking the concentration and alignment of P3HT and PCBM domains. Using this new procedure, devices are made with power conversion efficiencies surpassing 2%. Additionally, we show that nanowires grown in the presence of the fullerene perform differently than those that are grown and mixed separately; exposure to the nanowire during self-assembly may allow the fullerene to coat nanowire surfaces and influence the photocurrent within the device. Furthermore, because we are able to carefully control the regioregularity of our P3HT, we are able to produce a series of nanowires with regioregularities ranging between 93% and 99%. X-ray diffraction (XRD) shows that as the regioregularity of the polymer increases, the coherent domain size along the long-axis of the nanowires also becomes larger. When organic field effect transistors (OFETs) are made from these materials, the hole mobility of the nanowire films also has a positive correlation with regioregularity. As the domains within the nanowires grow larger, the frequency of domain boundaries decreases, allowing charges to percolate more efficiently along the nanowire. Additionally, we show that by introducing C60 into the active layer of P3HT:PCBM devices, we can modulate the crystal habit of the PCBM domains. Using optical microscopy and UV-vis absorption spectroscopy, we demonstrate that C60 additions alter the crystal morphology and greatly reduce the size of fullerene crystallites that are observed after extended annealing times and under aggressive aging conditions. We also show by fabricating organic field-effect transistors (OFETs) from PCBM:C60 blends that the incorporation of C60 does not adversely affect the electron mobility in these films. Finally, we show that as C60 is incorporated into P3HT:PCBM OPVs, devices become more thermally stable and do not degrade in performance as rapidly as traditional P3HT:PCBM blends. Lastly, the synthesis of four alternating copolymers using benzo[2,1- b;3,4-b']dithiophene (BDP) as the common donor unit is presented. Incorporating BDP, which consists of fused dithiophene units with a benzene ring, into these polymers should produce a low-lying highest occupied molecular orbital (HOMO) energy level. Low-lying HOMO levels are desirable to produce high open circuit voltages (V OC) in organic BHJ photovoltaic devices. The preliminary results of their performance in solar cells, using PCBM as the electron acceptor, is presented. The VOC values follow the expected trend: increasing with decreasing HOMO level of the polymer. High VOC values of 0.81 and 0.82 V have been obtained from two polymers: PBDPBT and PBDPDPP. The highest initial power conversion efficiency (PCE) achieved in these unoptimized devices was 1.11% due to relatively low JSC values. The variation observed in the J SC values between the four polymers is discussed. Device performance is expected to increase with optimization of processing conditions for the devices.

Fluticasone furoate/Vilanterol 92/22 μg once-a-day vs Beclomethasone dipropionate/Formoterol 100/6 μg b.I.D.: a 12-month comparison of outcomes in mild-to-moderate asthma.

Bronchial asthma is an inflammatory disease of the airways. Beclomethasone dipropionate/Formoterol (BDP/F) and Fluticasone furoate/Vilanterol (FF/V) are two of the most effective LABA/ICS combinations for managing persistent bronchial asthma. Aim of the study was to compare the outcomes achieved in mild-to-moderate asthma patients assuming BDP/F 100/6 μg b.i.d. (Group A) or FF/V 92/22 μg once-daily (Group B) for 12-months. No head-to-head long-term comparison is available at present. Data were automatically and anonymously obtained from the institutional database: FEV 1 % predicted values; the exacerbation and hospitalization rates; days of hospitalization; GP and/or specialist visits; days of inactivity; courses of systemic steroids and/or antibiotics were recorded at baseline and after 3, 6 and 12 months of both treatments. The overall adherence to treatments was also calculated. The propensity score method was used for matching and comparing the two cohorts of patients; Anova and Wilcoxon tests were used for checking the trends and time-to-time comparisons over the period; statistical significance was accepted for p  < 0.05. The PS-matching process returned a cohort of 40 group A patients matched with 40 patients of group B, fully comparable for demographics, clinical characteristics, and comorbidities. The improvement in lung function was significant in both groups ( p  < 0.001), even if it was significantly higher and time-dependent in group B. The mean (±SE) exacerbation rate/patient changed from 0.63 (±0.13) at baseline to 0.53 (±0.12) after three; to 0.58 (±0.13) after six, and to 0.60 (±0.18) after twelve months in group A (p = ns), while from of 1.05 (±0.16) at baseline, to 0.28 (±0.07) after three; to 0.33 (±0.08) after six, and to 0.18 (±0.08) after twelve months in group B ( p  < 0.001), respectively. The mean hospitalization rate/patient changed from 0.25 ± 0.07 at baseline to 0.15 (±0.06) after three; to 0.08 (±0.04) after six, and to 0.13 (±0.05) after twelve months in group A (p = ns), while from 0.30 (±0.07) at baseline to 0.08 (±0.04) after three; to 0.10 (±0.05) after six, and to 0.03 (±0.03) after twelve months in group B ( p  < 0.001), respectively. Also mean duration of hospitalization and days of inactivity were in favour of FF/V treatment over time (in both cases p  < 0.001). GP's visits were reduced by both treatments ( p  < 0.007 in group A and p < 0.001 in group B, respectively, while Specialist's visits only dropped during FF/V ( p  < 0.001). Steroid and antibiotic courses were significantly reduced by both treatments, even if more systematically in group B (p < 0.001 vs p  < 0.007, and p < 0.001 vs p  < 0.044, respectively). Moreover, changes in all outcomes considered proved time-dependent during the FF/V treatment only, particularly over the second semester. Finally, the overtime adherence to treatment was higher by 22 days during FF/V . Both the ICS/LABA combinations proved effective, even if characterized by different patterns of effectiveness either in terms of lung function and of long-term clinical outcomes. Only the once-daily inhalation of combined FF/V 92/22 μg once-daily optimized systematically the exacerbation and hospitalization rates in mild-to-moderate asthma, together with all other outcomes over time. The effectiveness of FF/V 92/22 once-daily μg proved progressive and time-dependent over the twelve-month period of the study, and associated to a higher adherence to treatment.

Organophosphorus flame retardants (PFRs) and emerging PFRs (ePFRs) are two groups of compounds used as replacements for brominated flame retardants (BFRs). They have already been detected in indoor dust (mainly in homes and offices). To date, few studies investigated the occurrence of FRs in car dust and the information of possible health risks is still limited. The present study reports on the investigation of the levels and profiles of eight target PFRs: tris(2-ethylhexyl) phosphate (TEHP), tris(2-chloroethyl) phosphate (TCEP), tris(2-butoxyethyl) phosphate (TBEP), triphenyl phosphate (TPHP), 2-ethylhexyl diphenyl phosphate (EHDPHP), tris(1-chloro-2-propyl) phosphate (TCIPP), tri cresyl phosphate (TCP), tris(1,3-dichloro-2-propyl) phosphate (TDCIPP) and four target ePFRs; 2,2-bis(chloromethyl)propane-1,3-diyltetrakis(2-chloroethyl)bisphosphate (V6), isodecyl diphenyl phosphate (iDDPHP), resorcinol bis(diphenylphosphate) (RDP) and bisphenol A-bis(diphenyl phosphate) (BDP) in car dust from Greece. The samples were collected from the interior of 25 private cars in Thessaloniki, Greece, with different years of manufacture (1997-2015) and continents of origin. After ultrasonic extraction and Florisil fractionation, the PFR analysis was carried out by GC-EI/MS, whereas the ePFRs were analyzed by LC-MS/MS. Levels of Σ 8 PFRs varied from 2000 to 190,000 ng g -1 , with mean and median concentrations of 20,000 and 11,500 ng g -1 , respectively. The concentrations of Σ 4 ePFRs ranged from 44 to 8700 ng g -1 , with mean and median values at 1100 and 190 ng g -1 , respectively. Estimations of human exposure showed that toddlers are more exposed than adults to both PFRs and ePFRs. Yet, the intake via dust ingestion and dermal absorption was several orders of magnitude lower than the corresponding reference doses. Copyright © 2017 Elsevier Ltd. All rights reserved.

The molecular pathogenesis of bipolar disorder (BPD) is poorly understood. Using human-induced pluripotent stem cells (hiPSCs) to unravel such mechanisms in polygenic diseases is generally challenging. However, hiPSCs from BPD patients responsive to lithium offered unique opportunities to discern lithium's target and hence gain molecular insight into BPD. By profiling the proteomics of BDP-hiPSC-derived neurons, we found that lithium alters the phosphorylation state of collapsin response mediator protein-2 (CRMP2). Active nonphosphorylated CRMP2, which binds cytoskeleton, is present throughout the neuron; inactive phosphorylated CRMP2, which dissociates from cytoskeleton, exits dendritic spines. CRMP2 elimination yields aberrant dendritogenesis with diminished spine density and lost lithium responsiveness (LiR). The "set-point" for the ratio of pCRMP2:CRMP2 is elevated uniquely in hiPSC-derived neurons from LiR BPD patients, but not with other psychiatric (including lithium-nonresponsive BPD) and neurological disorders. Lithium (and other pathway modulators) lowers pCRMP2, increasing spine area and density. Human BPD brains show similarly elevated ratios and diminished spine densities; lithium therapy normalizes the ratios and spines. Consistent with such "spine-opathies," human LiR BPD neurons with abnormal ratios evince abnormally steep slopes for calcium flux; lithium normalizes both. Behaviorally, transgenic mice that reproduce lithium's postulated site-of-action in dephosphorylating CRMP2 emulate LiR in BPD. These data suggest that the "lithium response pathway" in BPD governs CRMP2's phosphorylation, which regulates cytoskeletal organization, particularly in spines, modulating neural networks. Aberrations in the posttranslational regulation of this developmentally critical molecule may underlie LiR BPD pathogenesis. Instructively, examining the proteomic profile in hiPSCs of a functional agent-even one whose mechanism-of-action is unknown-might reveal otherwise inscrutable intracellular pathogenic pathways.

Traumatic Brain Injury (TBI) is a major cause of death and disability worldwide with 1.5 million people inflicted yearly. Several neurotherapeutic interventions have been proposed including drug administration as well as cellular therapy involving neural stem cells (NSCs). Among the proposed drugs is docosahexaenoic acid (DHA), a polyunsaturated fatty acid, exhibiting neuroprotective properties. In this study, we utilized an innovative intervention of neonatal NSCs transplantation in combination with DHA injections in order to ameliorate brain damage and promote functional recovery in an experimental model of TBI. Thus, NSCs derived from the subventricular zone of neonatal pups were cultured into neurospheres and transplanted in the cortex of an experimentally controlled cortical impact mouse model of TBI. The effect of NSC transplantation was assessed alone and/or in combination with DHA administration. Motor deficits were evaluated using pole climbing and rotarod tests. Using immunohistochemistry, the effect of transplanted NSCs and DHA treatment was used to assess astrocytic (Glial fibrillary acidic protein, GFAP) and microglial (ionized calcium binding adaptor molecule-1, IBA-1) activity. In addition, we quantified neuroblasts (doublecortin; DCX) and dopaminergic neurons (tyrosine hydroxylase; TH) expression levels. Combined NSC transplantation and DHA injections significantly attenuated TBI-induced motor function deficits (pole climbing test), promoted neurogenesis, coupled with an increase in glial reactivity at the cortical site of injury. In addition, the number of tyrosine hydroxylase positive neurons was found to increase markedly in the ventral tegmental area and substantia nigra in the combination therapy group. Immunoblotting analysis indicated that DHA+NSCs treated animals showed decreased levels of 38kDa GFAP-BDP (breakdown product) and 145kDa αII-spectrin SBDP indicative of attenuated calpain/caspase activation. These data demonstrate that prior treatment with DHA may be a desirable strategy to improve the therapeutic efficacy of NSC transplantation in TBI. Copyright © 2017 Elsevier B.V.

OSI-930, a potent thiophene inhibitor of the Kit, KDR, and platelet-derived growth factor receptor tyrosine kinases, was used to selectively inhibit tyrosine phosphorylation downstream of juxtamembrane mutant Kit in the mast cell leukemia line HMC-1. Inhibition of Kit kinase activity resulted in a rapid dephosphorylation of Kit and inhibition of the downstream signaling pathways. Attenuation of Ras-Raf-Erk (phospho-Erk, phospho-p38), phosphatidyl inositol-3' kinase (phospho-p85, phospho-Akt, phospho-S6), and signal transducers and activators of transcription signaling pathways (phospho-STAT3/5/6) were measured by affinity liquid chromatography tandem mass spectrometry, by immunoblot, and by tissue microarrays of fixed cell pellets. To more globally define additional components of Kit signaling temporally altered by kinase inhibition, a novel multiplex quantitative isobaric peptide labeling approach was used. This approach allowed clustering of proteins by temporal expression patterns. Kit kinase, which dephosphorylates rapidly upon kinase inhibition, was shown to regulate both Shp-1 and BDP-1 tyrosine phosphatases and the phosphatase-interacting protein PSTPIP2. Interactions with SH2 domain adapters [growth factor receptor binding protein 2 (Grb2), Cbl, Slp-76] and SH3 domain adapters (HS1, cortactin, CD2BP3) were attenuated by inhibition of Kit kinase activity. Functional crosstalk between Kit and the non-receptor tyrosine kinases Fes/Fps, Fer, Btk, and Syk was observed. Inhibition of Kit modulated phosphorylation-dependent interactions with pathways controlling focal adhesion (paxillin, leupaxin, p130CAS, FAK1, the Src family kinase Lyn, Wasp, Fhl-3, G25K, Ack-1, Nap1, SH3P12/ponsin) and septin-actin complexes (NEDD5, cdc11, actin). The combined use of isobaric protein quantitation and expression clustering, immunoblot, and tissue microarray strategies allowed temporal measurement signaling pathways modulated by mutant Kit inhibition in a model of mast cell leukemia.

Biomaterial compounds and bioactivity of horseshoe crab Carsinoscorpius rotundicauda biomass harvested from the Madura Strait

Carsinoscorpius rotundicauda or horseshoe crab biomass has great potential in pharmaceutical aspects, one of them as an antibacterial substance. Information related to the benefits of Carsinoscorpius rotundicauda biomass such as meat and blood is essential because in fact, this species is considered a pest by fishermen, a low market value and has no legal protection in Indonesia. The purpose of this study was to determine the content of biomaterial compounds of meat and bioactivity of Carsinoscorpius rotundicauda plasma on bacterial inhibition from three different stations harvested from the waters in Madura Strait. The observation of the utilization of the potential from horseshoe crab biomass ie meat and plasma was performed by measuring the content of biomaterial compound in horseshoe crab meat by HPLC method and zone of inhibition test for gram-positive and gram-negative bacteria in horseshoe crab plasma. Analysis of the relationship between the two parameters used the Principal Component Analysis. The highest content of biomaterial compounds of monoterpenoid and zoosterol is found in horseshoe crab from Bangkalan waters, namely monoterpenoid (18.33 ppm) and zoosterol (22.67 ppm), while the smallest compound content obtained in horseshoe crab from Probolinggo waters, namely monoterpenoid (13.67) ppm and zoosterol (17.33 ppm). The bioactivity of Dark Blue Plasma (BDP) and Light Blue Plasma (LBP) samples of horseshoe crab obtained around the Madura Strait has the ability to inhibit gram-positive bacteria higher than gram-negative bacteria. The total average of DBP plasma inhibitory power on Staphylococcus aureus was 10.00 mm and 10.07 mm on Bacillus, while that in LBP sample, Staphylococcus aureus was 9.11 mm and Bacillus was 9.67 mm. The high biomaterial compound content of horseshoe crab is in line with the ability of horseshoe crab plasma to inhibit Bacillus and Staphylococcus aureus.

Bodily Sensory Inputs and Anomalous Bodily Experiences in Complex Regional Pain Syndrome: Evaluation of the Potential Effects of Sound Feedback

PubMed Central

Tajadura-Jiménez, Ana; Cohen, Helen; Bianchi-Berthouze, Nadia

2017-01-01

Neuroscientific studies have shown that human's mental body representations are not fixed but are constantly updated through sensory feedback, including sound feedback. This suggests potential new therapeutic sensory approaches for patients experiencing body-perception disturbances (BPD). BPD can occur in association with chronic pain, for example in Complex Regional Pain Syndrome (CRPS). BPD often impacts on emotional, social, and motor functioning. Here we present the results from a proof-of-principle pilot study investigating the potential value of using sound feedback for altering BPD and its related emotional state and motor behavior in those with CRPS. We build on previous findings that real-time alteration of the sounds produced by walking can alter healthy people's perception of their own body size, while also resulting in more active gait patterns and a more positive emotional state. In the present study we quantified the emotional state, BPD, pain levels and gait of twelve people with CRPS Type 1, who were exposed to real-time alteration of their walking sounds. Results confirm previous reports of the complexity of the BPD linked to CRPS, as participants could be classified into four BPD subgroups according to how they mentally visualize their body. Further, results suggest that sound feedback may affect the perceived size of the CRPS affected limb and the pain experienced, but that the effects may differ according to the type of BPD. Sound feedback affected CRPS descriptors and other bodily feelings and emotions including feelings of emotional dominance, limb detachment, position awareness, attention and negative feelings toward the limb. Gait also varied with sound feedback, affecting the foot contact time with the ground in a way consistent with experienced changes in body weight. Although, findings from this small pilot study should be interpreted with caution, they suggest potential applications for regenerating BDP and its related bodily feelings in a clinical setting for patients with chronic pain and BPD.

2007-01-01

Background Clinical guidelines are considered important instruments to improve quality in health care. Since 1998 the Royal Dutch Society for Physical Therapy (KNGF) produced evidence-based clinical guidelines, based on a standardized program. New developments in the field of guideline research raised the need to evaluate and update the KNGF guideline program. Purpose of this study is to compare different guideline development programs and review the KNGF guideline program for physical therapy in the Netherlands, in order to update the program. Method Six international guideline development programs were selected, and the 23 criteria of the AGREE Instrument were used to evaluate the guideline programs. Information about the programs was retrieved from published handbooks of the organizations. Also, the Dutch program for guideline development in physical therapy was evaluated using the AGREE criteria. Further comparison the six guideline programs was carried out using the following elements of the guideline development processes: Structure and organization; Preparation and initiation; Development; Validation; Dissemination and implementation; Evaluation and update. Results Compliance with the AGREE criteria of the guideline programs was high. Four programs addressed 22 AGREE criteria, and two programs addressed 20 AGREE criteria. The previous Dutch program for guideline development in physical therapy lacked in compliance with the AGREE criteria, meeting only 13 criteria. Further comparison showed that all guideline programs perform systematic literature searches to identify the available evidence. Recommendations are formulated and graded, based on evidence and other relevant factors. It is not clear how decisions in the development process are made. In particular, the process of translating evidence into practice recommendations can be improved. Conclusion As a result of international developments and consensus, the described processes for developing clinical practice guidelines have much in common. The AGREE criteria are common basis for the development of guidelines, although it is not clear how final decisions are made. Detailed comparison of the different guideline programs was used for updating the Dutch program. As a result the updated KNGF program complied with 22 AGREE criteria. International discussion is continuing and will be used for further improvement of the program. PMID:18036215

Logic models as a tool for sexual violence prevention program development.

PubMed

Hawkins, Stephanie R; Clinton-Sherrod, A Monique; Irvin, Neil; Hart, Laurie; Russell, Sarah Jane

2009-01-01

Sexual violence is a growing public health problem, and there is an urgent need to develop sexual violence prevention programs. Logic models have emerged as a vital tool in program development. The Centers for Disease Control and Prevention funded an empowerment evaluation designed to work with programs focused on the prevention of first-time male perpetration of sexual violence, and it included as one of its goals, the development of program logic models. Two case studies are presented that describe how significant positive changes can be made to programs as a result of their developing logic models that accurately describe desired outcomes. The first case study describes how the logic model development process made an organization aware of the importance of a program's environmental context for program success; the second case study demonstrates how developing a program logic model can elucidate gaps in organizational programming and suggest ways to close those gaps.

Objective. To investigate published, peer-reviewed literature on pharmacy teaching and learning development programs and to synthesize existing data, examine reported efficacy and identify future areas for research. Methods. Medline and ERIC databases were searched for studies on teaching development programs published between 2001 and 2015. Results. Nineteen publications were included, representing 21 programs. Twenty programs were resident teaching programs, one program described faculty development. The majority of programs spanned one year and delivered instruction on teaching methodologies and assessment measures. All except one program included experiential components. Thirteen publications presented outcomes data; most measured satisfaction and self-perceived improvement. Conclusion. Published literature on teacher development in pharmacy is focused more on training residents than on developing faculty members. Although programs are considered important and highly valued by program directors and participants, little data substantiates that these programs improve teaching. Future research could focus on measurement of program outcomes and documentation of teaching development for existing faculty members. PMID:27293226

Seven community hospitals have worked cooperatively for 18 months to develop an initial hospital pharmacy quality assurance program. Auditing criteria were developed for nine service areas corresponding to the model program developed by the American Society of Hospital Pharmacists. Current plans are to implement and modify this program as required at each participating hospital. Follow-up programs will also be essential to a functional, ongoing program, and these will be developed in the future.

Developing a Family-Centered, Hospital-Based Perinatal Education Program

PubMed Central

Westmoreland, Marcia Haskins; Zwelling, Elaine

2000-01-01

The development of a family-centered, comprehensive perinatal education program for a large, urban hospital system is described. This program was developed in conjunction with the building of a new women's center and, although the authors were fortunate that several opportunities for educational program development were linked to this project, many of the steps taken and the lessons learned can be helpful to anyone desiring to develop a similar program. This article relates perinatal education to the principles of family-centered maternity care, outlines the criteria for a quality educational program, gives rationale for this type of program development, and offers practical suggestions for starting or enhancing a perinatal education program within a hospital system.

Evaluating Youth Development Programs: Progress and Promise

PubMed Central

Brooks-Gunn, Jeanne

2016-01-01

Advances in theories of adolescent development and positive youth development have greatly increased our understanding of how programs and practices with adolescents can impede or enhance their development. In this paper the authors reflect on the progress in research on youth development programs in the last two decades, since possibly the first review of empirical evaluations by Roth, Brooks-Gunn, Murray, and Foster (1998). The authors use the terms Version 1.0, 2.0 and 3.0 to refer to changes in youth development research and programs over time. They argue that advances in theory and descriptive accounts of youth development programs (Version 2.0) need to be coupled with progress in definitions of youth development programs, measurement of inputs and outputs that incorporate an understanding of programs as contexts for development, and stronger design and evaluation of programs (Version 3.0). The authors also advocate for an integration of prevention and promotion research, and for use of the term youth development rather than positive youth development. PMID:28077922

Characteristics of sports-based youth development programs.

PubMed

Perkins, Daniel F; Noam, Gil G

2007-01-01

The term "sports-based youth development programs" is coined and defined in the context of the community youth development framework. Sports-based youth development programs are out-of-school-time programs that use a particular sport to facilitate learning and life skill development in youth. Community youth development programs use a community youth development approach to create opportunities for youth to connect to others, develop skills, and use those skills to contribute to their communities. This, in turn, increases their ability to succeed. The authors describe how sports-based youth development programs can be contexts that promote positive youth development. The features of positive developmental settings for youth from the work of the National Research Council and the Institute of Medicine, as well as the features identified by other researchers, are presented in the context of sports-based youth development programs. For example, a sports program that provides appropriate structure has delineated clear rules, expectations, and responsibilities for youth, parents, coaches, officials, and other organizers.

Objectives. To describe characteristics of faculty development programs designed to facilitate interprofessional education, and to compile recommendations for development, delivery, and assessment of such faculty development programs. Methods. MEDLINE, CINAHL, ERIC, and Web of Science databases were searched using three keywords: faculty development, interprofessional education, and health professions. Articles meeting inclusion criteria were analyzed for emergent themes, including program design, delivery, participants, resources, and assessment. Results. Seventeen articles were identified for inclusion, yielding five characteristics of a successful program: institutional support; objectives and outcomes based on interprofessional competencies; focus on consensus-building and group facilitation skills; flexibility based on institution- and participant-specific characteristics; and incorporation of an assessment strategy. Conclusion. The themes and characteristics identified in this literature overview may support development of faculty development programs for interprofessional education. An advanced evidence base for interprofessional education faculty development programs is needed.

Thompson, Jon M; Temple, April

2015-01-01

Health care organizations are increasingly embracing leadership development programs. These programs include a variety of specific activities, such as formally structured leadership development, as well as mentoring, personal development and coaching, 360-degree feedback, and job enlargement, in order to increase the leadership skills of managers and high-potential staff. However, there is a lack of information on how early careerists in health care management view these programs and the degree to which they participate. This article reports on a study undertaken to determine how early careerists working in health care organizations view leadership development programs and their participation in such programs offered by their employers. Study findings are based on a survey of 126 early careerists who are graduates of an undergraduate health services administration program. We found varying levels of interest and participation in specific leadership development activities. In addition, we found that respondents with graduate degrees and those with higher compensation were more likely to participate in selected leadership development program activities. Implications of study findings for health care organizations and early careerists in the offering of, and participation in, leadership development programs are discussed.

Developing parenting programs to prevent child health risk behaviors: a practice model

PubMed Central

Jackson, Christine; Dickinson, Denise M.

2009-01-01

Research indicates that developing public health programs to modify parenting behaviors could lead to multiple beneficial health outcomes for children. Developing feasible effective parenting programs requires an approach that applies a theory-based model of parenting to a specific domain of child health and engages participant representatives in intervention development. This article describes this approach to intervention development in detail. Our presentation emphasizes three points that provide key insights into the goals and procedures of parenting program development. These are a generalized theoretical model of parenting derived from the child development literature, an established eight-step parenting intervention development process and an approach to integrating experiential learning methods into interventions for parents and children. By disseminating this framework for a systematic theory-based approach to developing parenting programs, we aim to support the program development efforts of public health researchers and practitioners who recognize the potential of parenting programs to achieve primary prevention of health risk behaviors in children.

We have created an education and career development program within the CTSA structure at OHSU that serves the entire institution. We believe that this is unusual in scope among CTSA programs and has contributed to an increase in career development funding and research skills among fellows and faculty. While the key element is the institutional scope, important elements include: Tailoring programs of emphasis to points of inflection on the career pathway. Minimizing barriers to education by creating a flexible, tuition-free program. An integrated one-stop education and career development approach. An institutional program for career development award applicants as well as recipients. This career development program was developed within the context of a midsize health science university but the overall strategy may be applied to other CTSAs to simplify and reduce costs of education program development.

Do less effective teachers choose professional development does it matter?

PubMed

Barrett, Nathan; Butler, J S; Toma, Eugenia F

2012-10-01

In an ongoing effort to improve teacher quality, most states require continuing education or professional development for their in-service teachers. Studies evaluating the effectiveness of various professional development programs have assumed a normal distribution of quality of teachers participating in the programs. Because participation in many professional development programs is either targeted or voluntary, this article suggests past evaluations of the effectiveness of professional development may be subject to selection bias and policy recommendations may be premature. This article presents an empirical framework for evaluating professional development programs where treatment is potentially nonrandom, and explicitly accounts for the teacher's prior effectiveness in the classroom as a factor that may influence participation in professional development. This article controls for the influence of selection bias on professional development outcomes by generating a matched sample based on propensity scores and then estimating the program's effect. In applying this framework to the professional development program examined in this article, less effective teachers are found to be more likely to participate in the program, and correcting for this selection leads to different conclusions regarding the program's effectiveness than when ignoring teacher selection patterns.

Implementing quality improvement programs that require behavior change on the part of health care professionals and patients has proven difficult in routine care. Significant randomized trial evidence supports creating fall prevention programs for community-dwelling older adults, but adoption in routine care has been limited. Nationally-collected data indicated that our local facility could improve its performance on fall prevention in community-dwelling older people. We sought to develop a sustainable local fall prevention program, using theory to guide program development. We planned program development to include important stakeholders within our organization. The theory-derived plan consisted of 1) an initial leadership meeting to agree on whether creating a fall prevention program was a priority for the organization, 2) focus groups with patients and health care professionals to develop ideas for the program, 3) monthly workgroup meetings with representatives from key departments to develop a blueprint for the program, 4) a second leadership meeting to confirm that the blueprint developed by the workgroup was satisfactory, and also to solicit feedback on ideas for program refinement. The leadership and workgroup meetings occurred as planned and led to the development of a functional program. The focus groups did not occur as planned, mainly due to the complexity of obtaining research approval for focus groups. The fall prevention program uses an existing telephonic nurse advice line to 1) place outgoing calls to patients at high fall risk, 2) assess these patients' risk factors for falls, and 3) triage these patients to the appropriate services. The workgroup continues to meet monthly to monitor the progress of the program and improve it. A theory-driven program development process has resulted in the successful initial implementation of a fall prevention program.

From professional development for science teachers to student learning in science

NASA Astrophysics Data System (ADS)

Tinoca, Luis Fonseca

This study investigates the effects of professional development for science teachers on student learning. It is usually expected that professional development programs positively impact student learning, however this dimension is not commonly incorporated in the programs evaluation. It is simply assumed that students will be indirectly impacted through their participating teachers in the work with their students. Two main research questions are addressed: (1) Are professional development programs effective in enhancing student learning in science? (2) What are the characteristics of the most and least effective programs? To answer these questions a meta-analysis of 37 professional development programs reporting their impact on student learning was performed. Program characteristics have been defined according to the categories defined by Loucks-Horsley et al (1998), the National Science Education Standards (NRC, 1996), as well as new categories developed by us analyzing other variables such as the programs length. A significant impact of professional development for science teachers on student learning has been found in the form of an overall correlation effect size of r = 0.22 (p < 0.001). Moreover, a Fixed Effects Model was used to differentiate between the impacts of the different characteristics of professional development programs for science teachers. In particular, programs emphasizing work on curriculum development, replacement, or implementation, scientific inquiry, pedagogical content knowledge, lasting over 6 month and with a total duration of at least 100 hours have been identified as having a larger impact on student learning. To enhance the findings vignettes have been developed based on the attained effect sizes describing possible professional development programs. Recommendations for present and future professional development programs are made based on what works best in order to maximize their impact on student learning.

The present paper is a longitudinal study which aims to develop and deliver cancer nursing education conferences in Honduras using volunteer nurse educators. This program intends to (1) perform site assessments of work environments and resources for cancer care in Honduras, (2) develop cancer nursing education programs, (3) survey conference participants continuing education needs, (4) deliver cancer nursing education conferences, and (5) share data with local and global partners for future cancer programs. The study draws on a longitudinal program development with site assessments, data collection, and educational conferences at two time points. Assessments and surveys were used for conference development and delivery by volunteer nurse educators. Site assessments and conferences were delivered twice. Data were collected regarding assessments and surveys to inform program development. Survey data revealed that <4 % had formal training in cancer care and >65 % had internet access. Participants desired more information about handling of chemotherapy, symptom management, and palliative care. Volunteer nurse educators perform site assessments and develop educational programming for cancer nurses. Local and global partners should explore internet-based programs between site visits to create sustainable education programs.

Overview of Advanced Turbine Systems Program

NASA Astrophysics Data System (ADS)

Webb, H. A.; Bajura, R. A.

The US Department of Energy initiated a program to develop advanced gas turbine systems to serve both central power and industrial power generation markets. The Advanced Turbine Systems (ATS) Program will lead to commercial offerings by the private sector by 2002. ATS will be developed to fire natural gas but will be adaptable to coal and biomass firing. The systems will be: highly efficient (15 percent improvement over today's best systems); environmentally superior (10 percent reduction in nitrogen oxides over today's best systems); and cost competitive (10 percent reduction in cost of electricity). The ATS Program has five elements. Innovative cycle development will lead to the demonstration of systems with advanced gas turbine cycles using current gas turbine technology. High temperature development will lead to the increased firing temperatures needed to achieve ATS Program efficiency goals. Ceramic component development/demonstration will expand the current DOE/CE program to demonstrate industrial-scale turbines with ceramic components. Technology base will support the overall program by conducting research and development (R&D) on generic technology issues. Coal application studies will adapt technology developed in the ATS program to coal-fired systems being developed in other DOE programs.

2009-01-01

Prospective, ongoing faculty development programs are important in the initial orientation and short- and long-term development of faculty in higher education. Pharmacy practice faculty are likely to benefit from a comprehensive faculty development program due to the complex nature of their positions, incomplete training in select areas, and multiple demands on their time. The need for faculty development programs is supported by the increased need for pharmacy practice faculty due to the increased number of colleges and schools of pharmacy, expanding enrollment in existing colleges and schools, and loss of existing senior faculty to retirement or other opportunities within or outside the academy. This White Paper describes a comprehensive faculty development program that is designed to enhance the satisfaction, retention, and productivity of new and existing pharmacy practice faculty. A comprehensive faculty development program will facilitate growth throughout a faculty member's career in pertinent areas. The structure of such a program includes an orientation program to provide an overview of responsibilities and abilities, a mentoring program to provide one-on-one guidance from a mentor, and a sustained faculty development program to provide targeted development based on individual and career needs. The content areas to be covered in each component include the institution (e.g., culture, structure, roles, responsibilities), student-related activities, teaching abilities, scholarship and research abilities, practice abilities and the practice site, and professional abilities (e.g., leadership, career planning, balancing responsibilities). A general framework for a comprehensive pharmacy practice faculty development program is provided to guide each college, school, department, and division in the design and delivery of a program that meets the needs and desires of the institution and its faculty.

Effective Practices for Evaluating Education and Public Outreach Programs

NASA Astrophysics Data System (ADS)

Wilkerson, S.

2013-12-01

Stephanie Baird Wilkerson, PhD Carol Haden EdD Magnolia Consulting,LLC Education and public outreach (EPO) program developers and providers seeking insights regarding effective practices for evaluating EPO activities programs benefit from understanding why evaluation is critical to the success of EPO activities and programs, what data collection methods are appropriate, and how to effectively communicate and report findings. Based on our extensive experience evaluating EPO programs, we will share lessons learned and examples of how these practices play out in actual evaluation studies. EPO program developers, providers, and evaluators must consider several factors that influence which evaluation designs and data collection methods will be most appropriate, given the nature of EPO programs. Effective evaluation practices of EPO programs take into account a program's phase of development, duration, and budget as well as a program's intended outcomes. EPO programs that are just beginning development will have different evaluation needs and priorities than will well-established programs. Effective evaluation practices consider the 'life' of a program with an evaluation design that supports a program's growth through various phases including development, revision and refinement, and completion. It would be premature and inappropriate to expect the attainment of longer-term outcomes of activities during program development phases or early stages of implementation. During program development, EPO providers should clearly define program outcomes that are feasible and appropriate given a program's scope and expected reach. In many respects, this directly relates to the amount of time, or duration, intended audiences participate in EPO programs. As program duration increases so does the likelihood that the program can achieve longer-term outcomes. When choosing which outcomes are reasonable to impact and measure, program duration should be considered. Effective evaluation practices include selecting appropriate data collection methods given a program's duration and corresponding intended outcomes. Data collection methods for programs of short duration might involve simple evaluation activities, whereas programs of longer duration might involve ongoing data collection measures including longitudinal student surveys, implementation logs, student journals, and student achievement measures. During our presentation, we will share examples from our own experience to illustrate how effective evaluation practices can be applied to various EPO programs based on program duration. Irrespective of duration, we find that EPO program developers and providers want both formative feedback to guide improvements and summative feedback on outcomes. More often than not, evaluation budgets for EPO programs are meager at best, yet come with the same information needs and priorities as programs with larger evaluation budgets. So how do program providers get the information they need given their limited funds for evaluation? We will offer several recommendations for helping EPO program providers work with evaluators to become better-informed consumers of evaluation by maximizing evaluation offerings and minimizing costs. During our presentation we also will share examples of communicating and reporting results for EPO program developers, EPO facilitators and practitioners, and funders.

A potential role of anti-poverty programs in health promotion

PubMed Central

Silverman, Kenneth; Holtyn, August F.; Jarvis, Brantley

2016-01-01

Poverty is one of the most pervasive risk factors underlying poor health, but is rarely targeted to improve health. Research on the effects of anti-poverty interventions on health has been limited, at least in part because funding for that research has been limited. Anti-poverty programs have been applied on a large scale, frequently by governments, but without systematic development and cumulative programmatic experimental studies. Anti-poverty programs that produce lasting effects on poverty have not been developed. Before evaluating the effect of anti-poverty programs on health, programs must be developed that can reduce poverty consistently. Anti-poverty programs require systematic development and cumulative programmatic scientific evaluation. Research on the therapeutic workplace could provide a model for that research and an adaptation of the therapeutic workplace could serve as a foundation of a comprehensive anti-poverty program. Once effective anti-poverty programs are developed, future research could determine if those programs improve health in addition to increasing income. The potential personal, health and economic benefits of effective anti-poverty programs could be substantial, and could justify the major efforts and expenses that would be required to support systematic research to develop such programs.

Leadership development programs for health care middle managers: An exploration of the top management team member perspective.

PubMed

Whaley, Alan; Gillis, William E

Hospitals throughout the United States establish leadership and management programs for their middle managers. Despite their pervasiveness and an increased emphasis on physician leadership, there is limited research regarding the development programs designed for clinical and nonclinical health care middle managers. Using two theoretical lenses, signaling and institutional theory, this exploratory study investigates mid-sized hospital development programs from the perspective of top management team (TMT) members. Our objective is to find out what types of programs hospitals have, how they are developed, and how they are evaluated. We conducted semistructured interviews with 13 TMT members in six purposefully selected hospitals and matched these interviews with program curricula. Careful coding of the data allowed us not only to show our data in a meaningful visual representation but also to show the progression of the data from raw form to aggregate themes in the qualitative research process. We identified four types of development programs used in the selected hospitals: (a) ongoing series, (b) curriculum-based, (c) management orientation, and (d) mentoring. Challenges existed in aligning the need for the program with program content. Communication occurred both through direct messaging regarding policies and procedures and through hidden signals. TMT members referenced other programs for guidance but were not always clear about what it is they wanted the programs to accomplish. Finally, there was limited program outcome measurement. Our small sample indicates that specific, structured, and comprehensive programs perform best. The better programs were always trying to improve but that most needed better accountability of tracking outcomes. In setting up a program, a collaborative approach among TMT members to establish what the needs are and how to measure outcomes worked well. Successful programs also tied in their leadership development with overall employee development.

Residency is an intense period. Challenges, including burnout, arise as new physicians develop their professional identities. Residency programs provide remediation, but emotional support for interns is often limited. Professional development coaching of interns, regardless of their performance, has not been reported. Design, implement, and evaluate a program to support intern professional development through positive psychology coaching. We implemented a professional development coaching program in a large residency program. The program included curriculum development, coach-intern interactions, and evaluative metrics. A total of 72 internal medicine interns and 26 internal medicine faculty participated in the first year. Interns and coaches were expected to meet quarterly; expected time commitments per year were 9 hours (per individual coached) for coaches, 5 1/2 hours for each individual coachee, and 70 hours for the director of the coaching program. Coaches and interns were asked to complete 2 surveys in the first year and to participate in qualitative interviews. Eighty-two percent of interns met with their coaches 3 or more times. Coaches and their interns assessed the program in multiple dimensions (participation, program and professional activities, burnout, coping, and coach-intern communication). Most of the interns (94%) rated the coaching program as good or excellent, and 96% would recommend this program to other residency programs. The experience of burnout was lower in this cohort compared with a prior cohort. There is early evidence that a coaching program of interactions with faculty trained in positive psychology may advance intern development and partially address burnout.

A growing body of evidence demonstrates that text messaging-based programs (short message service [SMS]) on mobile phones can help people modify health behaviors. Most of these programs have consisted of automated and sometimes interactive text messages that guide a person through the process of behavior change. This paper provides guidance on how to develop text messaging programs aimed at changing health behaviors. Based on their collective experience in designing, developing, and evaluating text messaging programs and a review of the literature, the authors drafted the guide. One author initially drafted the guide and the others provided input and review. Steps for developing a text messaging program include conducting formative research for insights into the target audience and health behavior, designing the text messaging program, pretesting the text messaging program concept and messages, and revising the text messaging program. The steps outlined in this guide may help in the development of SMS-based behavior change programs.

Astronomy for a Better World: IAU OAD Task Force-1 Programs for Advancing Astronomy Education and Research in Universities in Developing Countries

Guinan, Edward; Kolenberg, Katrien

2015-03-01

We discuss the IAU Commission 46 and Office for Astronomy Development (OAD) programs that support advancing Astronomy education and research primarily in universities in developing countries. The bulk of these operational activities will be coordinated through the OAD's newly installed Task Force 1. We outline current (and future) IAU/OAD Task Force-1 programs that promote the development of University-level Astronomy at both undergraduate and graduate levels. Among current programs discussed are the past and future expanded activities of the International School for Young Astronomers (ISYA) and the Teaching Astronomy for Development (TAD) programs. The primary role of the ISYA program is the organization of a three week School for students for typically M.Sc. and Ph.D students. The ISYA is a very successful program that will now be offered more frequently through the generous support of the Kavli Foundation. The IAU/TAD program provides aid and resources for the development of teaching, education and research in Astronomy. The TAD program is dedicated to assist countries that have little or no astronomical activity, but that wish to develop or enhance Astronomy education. Over the last ten years, the ISYA and TAD programs have supported programs in Africa, Asia, Central America and the Caribbean, the Middle East, South East and West Asia, and South America. Several examples are given. Several new programs being considered by OAD Task Force-1 are also discussed. Other possible programs being considered are the introduction of modular Astronomy courses into the university curricula (or improve present courses) as well as providing access to ``remote learning`` courses and Virtual Astronomy labs in developing countries. Another possible new program would support visits of astronomers from technically advanced countries to spend their sabbatical leaves teaching and advising University Astronomy programs in developing countries. Suggestions for new Task Force -1 programs are also welcomed. Useful information about the participation of IAU members and volunteers in these programs will be discussed and practical information will be provided.

Faculty development activities in family medicine: in search of innovation.

PubMed

Lawrence, Elizabeth A; Oyama, Oliver N

2013-01-01

To describe the Accreditation Council for Graduate Medical Education's (ACGME) faculty development requirements, explore the range of faculty development activities and support currently used by family medicine residencies to meet these requirements, and describe one innovative approach to satisfy this need. An electronic survey of faculty development activities and support offered to faculty by residency programs was sent to a random sample of 40 medical school and community based family medicine residency programs across the United States. Data were examined using t-tests, Fisher's exact tests, and Analysis of Variance. Faculty development, beyond traditional clinical CME, was strongly encouraged or required by a large proportion of the sample (73%). Only 58% of programs reported having discussed the ACGME's faculty development component areas (clinical, educational, administrative, leadership, research, and behavioral). In each component area except the "clinical" area, the absence of discussing the ACGME component areas with residency faculty was associated with fewer faculty development activities and support being offered by the program. These results, although preliminary, suggest that family medicine residency programs may value and encourage faculty development. The majority of programs use traditional activities and strategies such as CME, faculty meetings, faculty conferences and workshops; and a smaller number of programs are exploring the utility of mentoring programs, faculty discussion groups, and technology based learning systems. The challenge is to develop faculty development activities tailored to individual program and faculty needs and resources.

The Guidelines for Creating, Implementing, and Evaluating Mind-Body Programs in a Military Healthcare Setting outline key strategies and issues to consider when developing, implementing, and evaluating a mind-body focused family empowerment approach in a military healthcare setting. Although these guidelines were developed specifically for a military setting, most of the same principles can be applied to the development of programs in the civilian setting as well. The guidelines particularly address issues unique to mind-body programs, such as choosing evidence-based modalities, licensure and credentialing, safety and contraindications, and choosing evaluation measures that capture the holistic nature of these types of programs. The guidelines are practical, practice-based guidelines, developed by experts in the fields of program development and evaluation, mind-body therapies, patient- and family-centered care, as well as, experts in military and veteran's health systems. They provide a flexible framework to create mind-body family empowerment programs and describe important issues that program developers and evaluators are encouraged to address to ensure the development of the most impactful, successful, evidence-supported programs possible.

Kim, Ji Soo

2010-04-01

The purpose of the study is to develop a web-based program on child health care, and to identify the effect of the program on knowledge of, attitudes towards child health care, and health care practice in staff of daycare centers. The program was developed through the processes of needs analysis, contents construction, design, development, and evaluation. After the program was developed, it was revised through feedback from 30 experts. To identify the effect of developed program, onegroup pretest-posttest design study was conducted with 64 staff members from 12 daycare centers in Korea. The program was developed based on users' needs and consisted of five parts: health promotion, disease and symptoms management, oral health, injury and safety, sheets and forms. This study showed that the total score of staff who used the program was significantly higher in terms of knowledge, attitudes, and their health care practice compared with pretest score (p<.05). These results suggest that this Web-based program can contribute to the child health promotion as well as can provide the staff with the insightful child health information. Therefore, it is expected that this program will be applied to staff of other child care settings for children's health.

Academic medicine has initiated changes in policy, practice, and programs over the past several decades to address persistent gender disparity and other issues pertinent to its sociocultural context. Three career development programs were implemented to prepare women faculty to succeed in academic medicine: two sponsored by the Association of American Medical Colleges, which began a professional development program for early career women faculty in 1988. By 1995, it had evolved into two programs one for early career women and another for mid-career women. By 2012, more than 4000 women faculty from medical schools across the U.S and Canada had participated in these intensive 3-day programs. The third national program, the Hedwig van Ameringen Executive Leadership in Academic Medicine(®) (ELAM) program for women, was developed in 1995 at the Drexel University College of Medicine. Narratives from telephone interviews representing reflections on 78 career development seminars between 1988 and 2010 describe the dynamic relationships between individual, institutional, and sociocultural influences on participants' career advancement. The narratives illuminate the pathway from participating in a career development program to self-defined success in academic medicine in revealing a host of influences that promoted and/or hindered program attendance and participants' ability to benefit after the program in both individual and institutional systems. The context for understanding the importance of these career development programs to women's advancement is nestled in the sociocultural environment, which includes both the gender-related influences and the current status of institutional practices that support women faculty. The findings contribute to the growing evidence that career development programs, concurrent with strategic, intentional support of institutional leaders, are necessary to achieve gender equity and diversity inclusion.

Abstract Background: Academic medicine has initiated changes in policy, practice, and programs over the past several decades to address persistent gender disparity and other issues pertinent to its sociocultural context. Three career development programs were implemented to prepare women faculty to succeed in academic medicine: two sponsored by the Association of American Medical Colleges, which began a professional development program for early career women faculty in 1988. By 1995, it had evolved into two programs one for early career women and another for mid-career women. By 2012, more than 4000 women faculty from medical schools across the U.S and Canada had participated in these intensive 3-day programs. The third national program, the Hedwig van Ameringen Executive Leadership in Academic Medicine® (ELAM) program for women, was developed in 1995 at the Drexel University College of Medicine. Methods: Narratives from telephone interviews representing reflections on 78 career development seminars between 1988 and 2010 describe the dynamic relationships between individual, institutional, and sociocultural influences on participants' career advancement. Results: The narratives illuminate the pathway from participating in a career development program to self-defined success in academic medicine in revealing a host of influences that promoted and/or hindered program attendance and participants' ability to benefit after the program in both individual and institutional systems. The context for understanding the importance of these career development programs to women's advancement is nestled in the sociocultural environment, which includes both the gender-related influences and the current status of institutional practices that support women faculty. Conclusions: The findings contribute to the growing evidence that career development programs, concurrent with strategic, intentional support of institutional leaders, are necessary to achieve gender equity and diversity inclusion.

Genetic Programming as Alternative for Predicting Development Effort of Individual Software Projects

PubMed Central

Chavoya, Arturo; Lopez-Martin, Cuauhtemoc; Andalon-Garcia, Irma R.; Meda-Campaña, M. E.

2012-01-01

Statistical and genetic programming techniques have been used to predict the software development effort of large software projects. In this paper, a genetic programming model was used for predicting the effort required in individually developed projects. Accuracy obtained from a genetic programming model was compared against one generated from the application of a statistical regression model. A sample of 219 projects developed by 71 practitioners was used for generating the two models, whereas another sample of 130 projects developed by 38 practitioners was used for validating them. The models used two kinds of lines of code as well as programming language experience as independent variables. Accuracy results from the model obtained with genetic programming suggest that it could be used to predict the software development effort of individual projects when these projects have been developed in a disciplined manner within a development-controlled environment.

Viljoen, Myra; Coetzee, Isabel; Heyns, Tanya

2016-12-01

Society demands competent and safe health care, which obligates professionals to deliver quality patient care using current knowledge and skills. Participation in continuous professional development programs is a way to ensure quality nursing care. Despite the importance of continuous professional development, however, critical care nurse practitioners' attendance rates at these programs is low. To explore critical care nurses' reasons for their unsatisfactory attendance at a continuous professional development program. A nominal group technique was used as a consensus method to involve the critical care nurses and provide them the opportunity to reflect on their experiences and challenges related to the current continuous professional development program for the critical care units. Participants were 14 critical care nurses from 3 critical care units in 1 private hospital. The consensus was that the central theme relating to the unsatisfactory attendance at the continuous professional development program was attitude. In order of importance, the 4 contributing priorities influencing attitude were communication, continuous professional development, time constraints, and financial implications. Attitude relating to attending a continuous professional development program can be changed if critical care nurses are aware of the program's importance and are involved in the planning and implementation of a program that focuses on the nurses' individual learning needs. ©2016 American Association of Critical-Care Nurses.

Designing an orientation program for new faculty.

Holyfield, Lavern J; Berry, Charles W

2008-12-01

The Faculty Development Committee (FDC) at Baylor College of Dentistry (BCD) is charged with providing programs and activities that facilitate the success of existing faculty in the constantly changing environment of academia. In response to concerns regarding the challenges wrought by current and projected shortages of dental faculty across the nation, the FDC was prompted to assess development opportunities available to BCD faculty. A professional development resource that we found deficient was a formal, comprehensive orientation program for newly hired faculty. To guide the efforts of the committee in developing this program, a survey was designed and administered during an annual faculty retreat. Respondents were new and junior faculty, senior faculty, and some administrators. The results of the survey to determine requirements for new faculty orientation became the basis for formalizing BCD's new faculty orientation program. This article provides an overview of the new faculty orientation process from design to program implementation and describes the development and use of a faculty survey to determine the fundamental elements of a faculty development program, identification of essential individuals for designing/implementing the program, and implementation of a new faculty orientation program at BCD.

Intervention mapping: a process for developing theory- and evidence-based health education programs.

PubMed

Bartholomew, L K; Parcel, G S; Kok, G

1998-10-01

The practice of health education involves three major program-planning activities: needs assessment, program development, and evaluation. Over the past 20 years, significant enhancements have been made to the conceptual base and practice of health education. Models that outline explicit procedures and detailed conceptualization of community assessment and evaluation have been developed. Other advancements include the application of theory to health education and promotion program development and implementation. However, there remains a need for more explicit specification of the processes by which one uses theory and empirical findings to develop interventions. This article presents the origins, purpose, and description of Intervention Mapping, a framework for health education intervention development. Intervention Mapping is composed of five steps: (1) creating a matrix of proximal program objectives, (2) selecting theory-based intervention methods and practical strategies, (3) designing and organizing a program, (4) specifying adoption and implementation plans, and (5) generating program evaluation plans.

Promoting Success: A Professional Development Coaching Program for Interns in Medicine

Palamara, Kerri; Kauffman, Carol; Stone, Valerie E.; Bazari, Hasan; Donelan, Karen

2015-01-01

Background Residency is an intense period. Challenges, including burnout, arise as new physicians develop their professional identities. Residency programs provide remediation, but emotional support for interns is often limited. Professional development coaching of interns, regardless of their performance, has not been reported. Objective Design, implement, and evaluate a program to support intern professional development through positive psychology coaching. Methods We implemented a professional development coaching program in a large residency program. The program included curriculum development, coach-intern interactions, and evaluative metrics. A total of 72 internal medicine interns and 26 internal medicine faculty participated in the first year. Interns and coaches were expected to meet quarterly; expected time commitments per year were 9 hours (per individual coached) for coaches, 5 1/2 hours for each individual coachee, and 70 hours for the director of the coaching program. Coaches and interns were asked to complete 2 surveys in the first year and to participate in qualitative interviews. Results Eighty-two percent of interns met with their coaches 3 or more times. Coaches and their interns assessed the program in multiple dimensions (participation, program and professional activities, burnout, coping, and coach-intern communication). Most of the interns (94%) rated the coaching program as good or excellent, and 96% would recommend this program to other residency programs. The experience of burnout was lower in this cohort compared with a prior cohort. Conclusions There is early evidence that a coaching program of interactions with faculty trained in positive psychology may advance intern development and partially address burnout. PMID:26692977

Lankshear, Sara; Huckstep, Sherri; Lefebre, Nancy; Leiterman, Janis; Simon, Deborah

2010-05-01

Home healthcare nurses often work in isolation and rarely have the opportunity to meet or congregate in one location. As a result, nurse leaders must possess unique leadership skills to supervise and manage a dispersed employee base from a distance. The nature of this dispersed workforce creates an additional challenge in the ability to identify future leaders, facilitate leadership capacity, and enhance skill development to prepare them for future leadership positions. The ALIVE (Actively Leading In Virtual Environments) web-based program was developed to meet the needs of leaders working in virtual environments such as the home healthcare sector. The program, developed through a partnership of three home healthcare agencies, used nursing leaders as content experts to guide program development and as participants in the pilot. Evaluation findings include the identification of key competencies for nursing leaders in the home healthcare sector, development of program learning objectives and participant feedback regarding program content and delivery.

Exploratory technology research program for electrochemical energy storage

NASA Astrophysics Data System (ADS)

Kinoshita, K.

1992-06-01

The U.S. Department of Energy's Office of Propulsion Systems provides support for an electrochemical energy storage program, that includes research and development (R&D) on advanced rechargeable batteries and fuel cells. A major goal of this program is to develop electrochemical power sources suitable for application in electric vehicles. The program centers on advanced systems that offer the potential for high performance and low life-cycle costs. The DOE Electrochemical Energy Storage Program is divided into two projects: the Electric Vehicle Advanced Battery Systems Development (EVABS) Program and the Exploratory Technology Research (ETR) Program. The EVABS Program management responsibility has been assigned to Sandia National Laboratory, and the Lawrence Berkeley Laboratory is responsible for management of the ETR Program. The EVABS and ETR Programs include an integrated matrix of R&D efforts designed to advance progress on several candidate electrochemical systems. The United States Advanced Battery Consortium (USABC), a tripartite undertaking between DOE, the U.S. automobile manufacturers and the Electric Power Research Institute (EPRI), was formed in 1991 to accelerate the development of advanced batteries for consumer EVs. The role of the ETR Program is to perform supporting research on the advanced battery systems under development by the USABC and EVABS Program, and to evaluate new systems with potentially superior performance, durability and/or cost characteristics. The specific goal of the ETR Program is to identify the most promising electrochemical technologies and transfer them to the USABC, the battery industry and/or the EVABS Program for further development and scaleup. This report summarizes the research, financial and management activities relevant to the ETR Program in FY 1991.

"Initiate-build-operate-transfer" - a strategy for establishing sustainable telemedicine programs not only in the developing countries.

PubMed

Latifi, Rifat

2011-01-01

Establishing sustainable telemedicine has become a goal of many developing countries around the world. Yet, despite initiatives from a select few individuals and on occasion from various governments, often these initiatives never mature to become sustainable programs. The introduction of telemedicine and e-learning in the Balkans has been a pivotal step in advancing the quality and availability of medical services in a region whose infrastructure and resources have been decimated by wars, neglect, lack of funding, and poor management. The concept and establishment of the International Virtual e-Hospital (IVeH) has significantly impacted telemedicine and e-health services in Kosova. The success of the IVeH in Kosova has led to the development of similar programs in other Balkan countries and other developing countries in the hope of modernizing and improving their healthcare infrastructure. A comprehensive, four-pronged strategy developed by IVeH "Initiate-Build-Operate-Transfer" (IBOT), may be a useful approach in establishing telemedicine and e-health educational services not only in developing countries, but in developed countries. The development strategy, IBOT, used by the IVeH to establish and develop telemedicine programs is described. IBOT includes assessment of healthcare needs of each country, the development of a curriculum and education program, the establishment of a nationwide telemedicine network, and the integration of the telemedicine program into the very core of healthcare infrastructure. The end point is the transfer of a sustainable telehealth program to the nation involved. By applying IBOT, a sustainable telemedicine program of Kosova and Albania has been established as an effective prototype for telemedicine in the Balkans. Once fully matured, the program is transitioned to the Ministry of Health, which ensures the sustainability and ownership of the program. Similar programs are being established in Macedonia, Montenegro and other countries around the world. The IBOT model has been effective in creating sustainable telemedicine and e-health integrated programs in the Balkans and may be a good model for establishing such programs in developing countries.

The U.S. Department of Energy (DOE) national laboratories use their expertise in nuclear science and technology (S&T) to support a robust national nuclear S&T enterprise from the ground up. Traditional academic programs do not provide all the elements necessary to develop this expertise, so the DOE has initiated a number of supplemental programs to develop and support the nuclear S&T workforce pipeline. This document catalogs existing workforce development programs that are supported by a number of DOE offices (such as the Offices of Nuclear Energy, Science, Energy Efficiency, and Environmental Management), and by the National Nuclear Security Administration (NNSA) andmore » the Naval Reactor Program. Workforce development programs in nuclear S&T administered through the Department of Homeland Security, the Nuclear Regulatory Commission, and the Department of Defense are also included. The information about these programs, which is cataloged below, is drawn from the program websites. Some programs, such as the Minority Serving Institutes Partnership Programs (MSIPPs) are available through more than one DOE office, so they appear in more than one section of this document.« less

Development of a Teen-Friendly Health Education Program on Facebook: Lessons Learned.

PubMed

Park, Bu Kyung; Nahm, Eun-Shim; Rogers, Valerie E

2016-01-01

Facebook is the most popular online platform among adolescents and can be an effective medium to deliver health education. Although Korean American (KA) adolescents are at risk of obesity, a culturally tailored health education program is not available for them. Thus, our research team developed a health education program for KA adolescents on Facebook called "Healthy Teens." The aim of this study was to discuss important lessons learned through the program development process. This program includes culturally tailored learning modules about healthy eating and physical activity. The program was developed on the basis of the social cognitive theory, and the online program was developed by applying Web usability principles for adolescents. Upon completion, the usability of the program was assessed using heuristic evaluation. The findings from the heuristic evaluation showed that the Healthy Teens program was usable for KA adolescents. The findings from this study will assist researchers who are planning to build similar Facebook-based health education programs.

Establishing sustainable telemedicine has become a goal of many developing countries around the world. Yet, despite initiatives from a select few individuals and on occasion from various governments, often these initiatives never mature to become sustainable programs. The introduction of telemedicine and e-learning in Kosova has been a pivotal step in advancing the quality and availability of medical services in a region whose infrastructure and resources have been decimated by wars, neglect, lack of funding, and poor management. The concept and establishment of the International Virtual e-Hospital (IVeH) has significantly impacted telemedicine and e-health services in the Balkans. The success of the IVeH in Kosova has led to the development of similar programs in other Balkan countries and other developing countries in the hope of modernizing and improving their healthcare infrastructure. A comprehensive, four-pronged strategy, "Initiate-Build-Operate-Transfer" (IBOT), may be a useful approach in establishing telemedicine and e-health educational services in developing countries. The development strategy, IBOT, used by the IVeH to establish and develop telemedicine programs, was discussed. IBOT includes assessment of healthcare needs of each country, the development of a curriculum and education program, the establishment of a nationwide telemedicine network, and the integration of the telemedicine program into the healthcare infrastructure. The endpoint is the transfer of a sustainable telehealth program to the nation involved. By applying IBOT, a sustainable telemedicine program of Kosova has been established as an effective prototype for telemedicine in the Balkans. Once fully matured, the program will be transitioned to the national Ministry of Health, which ensures the sustainability and ownership of the program. Similar programs are being established in Albania, Macedonia, and other countries around the world. The IBOT model has been effective in creating sustainable telemedicine and e-health integrated programs in the Balkans and may be a good model for establishing such programs in developing countries.

Background Exercise is an important therapy to improve well-being after a cancer diagnosis. Accordingly, cancer-exercise programs have been developed to enhance clinical care; however, few programs exist in Canada. Expansion of cancer-exercise programming depends on an understanding of the process of program implementation, as well as enablers and barriers to program success. Gaining knowledge from current professionals in cancer-exercise programs could serve to facilitate the necessary understanding. Methods Key personnel from Canadian cancer-exercise programs (n = 14) participated in semistructured interviews about program development and delivery. Results Content analysis revealed 13 categories and 15 subcategories, which were grouped by three organizing domains: Program Implementation, Program Enablers, and Program Barriers. ■ Program Implementation (5 categories, 8 subcategories) included Program Initiation (clinical care extension, research project expansion, program champion), Funding, Participant Intake (avenues of awareness, health and safety assessment), Active Programming (monitoring patient exercise progress, health care practitioner involvement, program composition), and Discharge and Follow-up Plan.■ Program Enablers (4 categories, 4 subcategories) included Patient Participation (personalized care, supportive network, personal control, awareness of benefits), Partnerships, Advocacy and Support, and Program Characteristics.■ Program Barriers (4 categories, 3 subcategories) included Lack of Funding, Lack of Physician Support, Deterrents to Participation (fear and shame, program location, competing interests), and Disease Progression and Treatment. Conclusions Interview results provided insight into the development and delivery of cancer-exercise programs in Canada and could be used to guide future program development and expansion in Canada.

Development of behavior theory-based health promotion programs is encouraged with the paradigm shift from contents to behavior outcomes. This article describes the development process of the diabetes self-management program for older Koreans (DSME-OK) using intervention mapping (IM) protocol. The IM protocol includes needs assessment, defining goals and objectives, identifying theory and determinants, developing a matrix to form change objectives, selecting strategies and methods, structuring the program, and planning for evaluation and pilot testing. The DSME-OK adopted seven behavior objectives developed by the American Association of Diabetes Educators as behavioral outcomes. The program applied an information-motivation-behavioral skills model, and interventions were targeted to 3 determinants to change health behaviors. Specific methods were selected to achieve each objective guided by IM protocol. As the final step, program evaluation was planned including a pilot test. The DSME-OK was structured as the 3 determinants of the IMB model were intervened to achieve behavior objectives in each session. The program has 12 weekly 90-min sessions tailored for older adults. Using the IM protocol in developing a theory-based self-management program was beneficial in terms of providing a systematic guide to developing theory-based and behavior outcome-focused health education programs.

The Italian severe/uncontrolled asthma (SUA) web-based registry encompasses demographic, clinical, functional, and inflammatory data; it aims to raise SUA awareness, identifying specific phenotypes and promoting optimal care. Four hundred and ninety three adult patients from 27 Italian centers (recruited in 2011-2014) were analyzed. Mean age was 53.8 years. SUA patients were more frequently female (60.6%), with allergic asthma (83.1%). About 30% showed late onset of asthma diagnosis/symptoms (>40 years); the mean age for asthma symptoms onset was 30.2 years and for asthma diagnosis 34.4 years. 97.1% used ICS (dose 2000 BDP), 93.6% LABA in association with ICS, 53.3% LTRAs, 64.1% anti-IgE, 10.7% theophylline, and 16.0% oral corticosteroids. Mean FEV 1 % pred of 75.1%, median values of 300/mm 3 of blood eosinophil count, 323 kU/L of serum total IgE, and 24 ppb of FENO were shown. Most common comorbidities were allergic rhinitis (62.4%), gastroesophageal reflux (42.1%), sinusitis (37.9%), nasal polyposis (30.2%), and allergic conjunctivitis (30.2%). 55.7% of SUA patients had exacerbations in the last 12 months, 9.7% emergency department visits, and 7.3% hospitalizations. Factors associated with exacerbation risk were obesity (OR, 95% CI 2.46, 1.11-5.41), psychic disorders (2.87, 0.89-9.30-borderline), nasal polyps (1.86, 0.88-3.89-borderline), partial/poor asthma treatment adherence (2.54, 0.97-6.67-borderline), and anti-IgE use in a protective way (0.26, 0.12-0.53). Comparisons to severe asthma multicenter studies and available registries showed data consistency across European and American populations. An international effort in the implementation of SUA patients' registries could help to better understand the clinical features and to manage severe asthma, representing a non-negligible socioeconomic burden for health services. © 2017 EAACI and John Wiley and Sons A/S.

Adaptation to bipolar disorder and perceived risk to children: a survey of parents with bipolar disorder.

Peay, Holly L; Rosenstein, Donald L; Biesecker, Barbara B

2013-12-02

Bipolar disorder (BPD) is a common condition associated with significant morbidity and reduced quality of life. In addition to challenges caused by their mood symptoms, parents affected with BPD harbor concerns about the mental health of their children. Among adult parents who perceive themselves to have BPD, this study aims to examine participants' coping methods; identify predictors of adaptation; assess parental perceptions of risks for mood disorders among their children; and describe the relationships among illness appraisals, coping, adaptation to one's own illness, and perceived risk to one's children. Parents who self-identified as having BPD completed a web-based survey that assessed dispositional optimism, coping, perceived illness severity, perceived etiology of BPD, perceived risk to offspring, and adaptation to BPD. Participants had at least one unaffected child who was 30 years of age or below. 266 parents were included in the analysis. 87% of parents endorsed a "somewhat greater" or "much greater" risk for mood disorders in one's child(ren) than someone without a family history. Endorsing a genetic/familial etiology to BPD was positively correlated with perceived risk for mood disorders in children (rs = .3, p < 0.01) and active coping with BDP (r = .2, p < 0.01). Increased active coping (β = 0.4, p < 0.001) and dispositional optimism (β = 0.3, p < 0.001) were positively associated with better adaptation, while using denial coping was negatively associated with adaptation (β = -0.3, p < 0.001). The variables explained 55.2% of the variance in adaptation (F = 73.2, p < 0.001). Coping mediated the effect of perceived illness severity on adaptation. These data inform studies of interventions that extend beyond symptom management and aim to improve the psychological wellbeing of parents with BPD. Interventions targeted at illness perceptions and those aimed at enhancing coping should be studied for positive effects on adaptation. Parents with BPD may benefit from genetic counseling to promote active coping with their condition, and manage worry about perceived risk to their children.

Characteristics of effective summer learning programs in practice.

PubMed

Bell, Susanne R; Carrillo, Natalie

2007-01-01

The Center for Summer Learning examined various summer program models and found that there are nine characteristics that provide a framework for effective summer programs. In this chapter, the authors demonstrate how effective practices lead to positive results for young people. The nine characteristics of effective summer learning programs are (1) accelerating learning, (2) youth development, (3) proactive approach to summer learning, (4) leadership, (5) advanced planning, (6) staff development, (7) strategic partnerships, (8) evaluation and commitment to program improvement, and (9) sustainability and cost-effectiveness. These characteristics are divided into two sections. The first three characteristics address a program's approach to learning. Summer instructional techniques are most effective when academic learning is woven into enrichment activities and youth development. The second section covers program infrastructure to ensure the organization achieves and maintains quality programming. The nine characteristics complement each other to ensure a strong program that works to prevent summer learning loss and narrow the achievement gap. To demonstrate the variety of high-quality programs that include the nine characteristics, thirteen program profiles at the conclusion of the chapter each highlight one of the characteristics. These profiles show the various approaches that different summer programs have developed to accelerate academic achievement and promote positive development for young people in their communities.

Piskorowski, Wilhelm A; Fitzgerald, Mark; Mastey, Jerry; Krell, Rachel E

2011-08-01

Increasing the use of community-based programs is an important trend in improving dental education to meet the needs of students and the public. To support this trend, understanding the history of programs that have established successful models for community-based education is valuable for the creation and development of new programs. The community-based education model of the University of Michigan School of Dentistry (UMSOD) offers a useful guide for understanding the essential steps and challenges involved in developing a successful program. Initial steps in program development were as follows: raising funds, selecting an outreach clinical model, and recruiting clinics to become partners. As the program developed, the challenges of creating a sustainable financial model with the highest educational value required the inclusion of new clinical settings and the creation of a unique revenue-sharing model. Since the beginning of the community-based program at UMSOD in 2000, the number of community partners has increased to twenty-seven clinics, and students have treated thousands of patients in need. Fourth-year students now spend a minimum of ten weeks in community-based clinical education. The community-based program at UMSOD demonstrates the value of service-based education and offers a sustainable model for the development of future programs.

Kinoshita, Kim

1994-09-01

The U.S. Department of Energy's Office of Propulsion Systems provides support for an Electrochemical Energy Storage Program, that includes research and development (R&D) on advanced rechargeable batteries and fuel cells. A major goal of this program is to develop electrochemical power sources suitable for application in electric vehicles (EV's). The program centers on advanced systems that offer the potential for high performance and low life-cycle costs, both of which are necessary to permit significant penetration into commercial markets. The DOE Electrochemical Energy Storage Program is divided into two projects: the Electric Vehicle Advanced Battery Systems (EVABS) Development Program and the Exploratory Technology Research (ETR) Program. The EVABS Program management responsibility has been assigned to Sandia National Laboratories (SNL); Lawrence Berkeley Laboratory (LBL) is responsible for management of the ETR Program. The EVABS and ETR Programs include an integrated matrix of R&D efforts designed to advance progress on selected candidate electrochemical systems. The United States Advanced Battery Consortium (USABC), a tripartite undertaking between DOE, the U.S. automobile manufacturers and the Electric Power Research Institute (EPRI), was formed in 1991 to accelerate the development of advanced batteries for consumer EV's. The role of the FIR Program is to perform supporting research on the advanced battery systems under development by the USABC and EVABS Program, and to evaluate new systems with potentially superior performance, durability and/or cost characteristics. The specific goal of the ETR Program is to identify the most promising electrochemical technologies and transfer them to the USABC, the battery industry and/or the EVABS Program for further development and scale-up. This report summarizes the research, financial and management activities relevant to the ETR Program in CY 1993.

How development programs can affect fertility: the case of Bangladesh.

PubMed

Robey, B

1988-09-01

Improving living standards and increasing productivity in developing countries may result in fertility reduction. In Bangladesh, government policy stresses rural development and fertility reduction. Programs that raise women's status reduce fertility. Educational level is inversely correlated to childbearing. Women aged 25-29 with a Secondary School Certificate have 2.4 children, versus 4.0 for those with no education. Employment also decreases fertility. Thus, improving the educational and employment status of women could have major effects on fertility. Studying the Bangladesh Rural Social Services program revealed that community organization efforts and self-help programs for economic and social improvement also decrease fertility. Rural electrification programs, which have been emphasized in development planning, contribute to changing attitudes and behavior of residents of these regions. In addition to electrification, improved transportation and communications should enhance the spread of information to rural areas. Agricultural development programs, such as the Comilla development program, have not affected fertility. This is attributed to the concentration of benefits to a few farms, with the majority becoming poorer. Unless agricultural development benefits are widely distributed, there will probably be little effect on fertility. Thus, the development programs most likely to affect fertility are those which emphasize female education and employment, open rural areas to information and ideas, and are open to a whole community.

Blum, Robert L.; Walker, Michael G.

1986-01-01

The LISP language provides a useful set of features for prototyping knowledge-intensive, clinical applications software that is not found In most other programing environments. Medical computer programs that need large medical knowledge bases, such as programs for diagnosis, therapeutic consultation, education, simulation, and peer review, are hard to design, evolve continually, and often require major revisions. They necessitate an efficient and flexible program development environment. The LISP language and programming environments bullt around it are well suited for program prototyping. The lingua franca of artifical intelligence researchers, LISP facllitates bullding complex systems because it is simple yet powerful. Because of its simplicity, LISP programs can read, execute, modify and even compose other LISP programs at run time. Hence, it has been easy for system developers to create programming tools that greatly speed the program development process, and that may be easily extended by users. This has resulted in the creation of many useful graphical interfaces, editors, and debuggers, which facllitate the development of knowledge-intensive medical applications.

Future Mars missions require new capabilities that currently are not available. The Mars Technology Program (MTP) is an integral part of the Mars Exploration Program (MEP). Its sole purpose is to assure that required technologies are developed in time to enable the baselined and future missions. The MTP is a NASA-wide technology development program managed by JPL. It is divided into a Focused Program and a Base Program. The Focused Program is tightly tied to the proposed Mars Program mission milestones. It involves time-critical deliverables that must be developed in time for infusion into the proposed Mars 2005, and, 2009 missions. In addition a technology demonstration mission by AFRL will test a LIDAR as part of a joint NASNAFRL experiment. This program bridges the gap between technology and projects by vertically integrating the technology work with pre-project development in a project-like environment with critical dates for technology infusion. A Base Technology Program attacks higher riskhigher payoff technologies not in the critical path of missions.

Abstract Mental health service users (MHSUs) have elevated rates of cardiometabolic disturbance. Improvements occur with physical activity (PA) programs. We report the development and evaluation of three innovative peer-developed and peer-led PA programs: 1) walking; 2) fitness; and 3) yoga. Qualitative evaluation with 33 MHSUs in British Columbia, Canada, occurred. These programs yielded improvements for participants, highlighted by powerful narratives of health improvement, and improved social connections. The feasibility and acceptability of innovative peer-developed and peer-led programs were shown. Analyses revealed concepts related to engagement and change. Relating core categories, we theorize effective engagement of MHSUs requires accessibility on three levels (geographic, cost, and program flexibility) and health behavior change occurs within co-constituent relationships (to self, to peers, and to the wider community). This study highlights the benefits of peer involvement in developing and implementing PA programs and provides a theoretical framework of understanding engagement and behavior change in health programs for MHSUs.

Developing a videocassette program for pharmacy education.

PubMed

Klamerus, K J; Belsheim, D J

1988-03-01

The development of a videocassette program to educate pharmacists about congestive heart failure (CHF) is described. The CHF videocassette program was developed to provide the equivalent of four hours of instruction to pharmacists in continuing-education programs or Pharm.D. degree programs. CHF was chosen as the topic because it is a common medical problem that pharmacists likely would encounter, and the material would lend itself well to visual illustration. A program-development team consisting of a pharmacist-author, an educational-design specialist, and a writer-producer was established. The group dealt first with treatment of ideas, or discussions of ways in which the educational material could best be illustrated. The pharmacist-author developed the text for the program, and the writer-producer converted the text into a script with numbered scenes. Information that could be presented more appropriately in written format was gathered into a supplemental guidebook. A storyboard script that linked the text with the audio and visual elements was developed with the help of a professional director and medical illustrator, and the program was filmed using volunteer and professional actors as well as simple animation. The program comprises two videocassettes that are 40 and 44 minutes long, respectively. The estimated cost of the production was +28,000, which includes estimates of the value of time volunteered by the pharmacist-author, educational-design specialist, nonprofessional talent, and secretaries. The program has been used for six continuing-education programs and two classes of Pharm.D. students; subjective evaluations of the program have been favorable. Videocassette technology can be applied successfully to educational programs for pharmacists.(ABSTRACT TRUNCATED AT 250 WORDS)

2017-11-15

The interprofessional development, implementation, and outcomes of a pharmacist professional advancement and recognition program (PARP) at an academic medical center are described. Limitations of the legacy advancement program, in combination with low rates of employee engagement in peer recognition and professional development, at the UW Health department of pharmacy led to the creation of a task force comprising pharmacists from all practice areas to develop a new pharmacist PARP. Senior leadership within the organization expanded the scope of the project to include an interprofessional work group tasked to develop guidelines and core principles that other professional staff could use to reduce variation across advancement and recognition programs. Key program design elements included a triennial review of performance against advancement standards and the use of peer review to supplement advancement decisions. The primary objective was to meaningfully improve pharmacists' engagement as measured through employee engagement surveys. Secondary outcomes of interest included the results of pharmacist and management satisfaction surveys and the program's impact on the volume and mix of pharmacist professional development activities. Of the 126 eligible pharmacists, 93 participated in the new program. The majority of pharmacists was satisfied with the program. For pharmacists who were advanced as part of the program, meaningful increases in employee engagement scores were observed, and a mean of 95 hours of professional development and quality-improvement activities was documented. Implementation of a PARP helped increase pharmacist engagement through participation in quality-improvement and professional development activities. The program also led to the creation of organizationwide interprofessional guidelines for advancement programs within various healthcare disciplines.

A Component-based Programming Model for Composite, Distributed Applications

NASA Technical Reports Server (NTRS)

Eidson, Thomas M.; Bushnell, Dennis M. (Technical Monitor)

2001-01-01

The nature of scientific programming is evolving to larger, composite applications that are composed of smaller element applications. These composite applications are more frequently being targeted for distributed, heterogeneous networks of computers. They are most likely programmed by a group of developers. Software component technology and computational frameworks are being proposed and developed to meet the programming requirements of these new applications. Historically, programming systems have had a hard time being accepted by the scientific programming community. In this paper, a programming model is outlined that attempts to organize the software component concepts and fundamental programming entities into programming abstractions that will be better understood by the application developers. The programming model is designed to support computational frameworks that manage many of the tedious programming details, but also that allow sufficient programmer control to design an accurate, high-performance application.

This study was designed to develop an evidence- and community based falls prevention program -- Tai Chi: Moving for Better Balance. A mixed qualitative and quantitative approach was used to develop a package of materials for program implementation and evaluation. The developmental work was conducted in 2 communities in the Pacific Northwest. Participants included a panel of experts, senior service program managers or activity coordinators, and older adults. Outcome measures involved program feasibility and satisfaction. Through an iterative process, a program package was developed. The package contained an implementation plan and class training materials (ie, instructor's manual, videotape, and user's guidebook). Pilot testing of program materials showed that the content was appropriate for the targeted users (community-living older adults) and providers (local senior service organizations). A feasibility survey indicated interest and support from users and providers for program implementation. A 2-week pilot evaluation showed that the program implementation was feasible and evidenced good class attendance, high participant satisfaction, and interest in continuing Tai Chi. The package of materials developed in this study provides a solid foundation for larger scale implementation and evaluation of the program in community settings.

Murphy, Andrea L; Gardner, David M; Kutcher, Stan P; Martin-Misener, Ruth

2014-01-01

Pharmacists are knowledgeable, accessible health care professionals who can provide services that improve outcomes in mental health care. Various challenges and opportunities can exist in pharmacy practice to hinder or support pharmacists' efforts. We used a theory-informed approach to development and implementation of a capacity-building program to enhance pharmacists' roles in mental health care. Theories and frameworks including the Consolidated Framework for Implementation Research, the Theoretical Domains Framework, and the Behaviour Change Wheel were used to inform the conceptualization, development, and implementation of a capacity-building program to enhance pharmacists' roles in mental health care. The More Than Meds program was developed and implemented through an iterative process. The main program components included: an education and training day; use of a train-the-trainer approach from partnerships with pharmacists and people with lived experience of mental illness; development of a community of practice through email communications, a website, and a newsletter; and use of educational outreach delivered by pharmacists. Theories and frameworks used throughout the program's development and implementation facilitated a means to conceptualize the component parts of the program as well as its overall presence as a whole from inception through evolution in implementation. Using theoretical foundations for the program enabled critical consideration and understanding of issues related to trialability and adaptability of the program. Theory was essential to the underlying development and implementation of a capacity-building program for enhancing services by pharmacists for people with lived experience of mental illness. Lessons learned from the development and implementation of this program are informing current research and evolution of the program.

2011-01-01

As NASA undertakes increasingly complex projects, the need for expert systems engineers and leaders in systems engineering is becoming more pronounced. As a result of this issue, the Agency has undertaken an initiative to develop more systems engineering leaders through its Systems Engineering Leadership Development Program; however, the NASA Office of the Chief Engineer has also called on the field Centers to develop mechanisms to strengthen their expertise in systems engineering locally. In response to this call, Marshall Space Flight Center (MSFC) has developed a comprehensive development program for aspiring systems engineers and systems engineering leaders. This presentation will summarize the two-level program, which consists of a combination of training courses and on-the-job, developmental training assignments at the Center to help develop stronger expertise in systems engineering and technical leadership. In addition, it will focus on the success the program has had in its pilot year. The program hosted a formal kickoff event for Level I on October 13, 2009. The first class includes 42 participants from across MSFC and Michoud Assembly Facility (MAF). A formal call for Level II is forthcoming. With the new Agency focus on research and development of new technologies, having a strong pool of well-trained systems engineers is becoming increasingly more critical. Programs such as the Marshall Systems Engineering Leadership Development Program, as well as those developed at other Centers, help ensure that there is an upcoming generation of trained systems engineers and systems engineering leaders to meet future design challenges.

Recognizing that over half of STEM Ph.D. graduates are finding work outside of academia, a new, NSF-funded program at Syracuse University, EMPOWER (or Education Model Program on Water-Energy Research) is encouraging its graduate students to take ownership of their graduate program and design it to meet their anticipated needs. Launched in 2016, EMPOWER's goal is to prepare graduate students for careers in the water-energy field by offering targeted workshops, professional training coursework, a career capstone experience, a professional development mini-grant program, and an interdisciplinary "foundations" seminar. Through regular student feedback and program evaluation, EMPOWER has learned some important lessons this first year: career options and graduate students' interests are diverse, requiring individualized programs designed to meet the needs of prospective employers and employees; students need exposure to the range of careers in their field to provide a roadmap for designing their own graduate school experience; effective programs nurture a culture that values professional development thereby giving students permission to pursue career paths and professional development opportunities that meet their own needs and interests; and existing university resources support the effective and efficient integration of professional development activities into graduate programs. Many of the positive outcomes experienced by EMPOWER students may be achieved in departmental graduate programs with small changes to their graduate curricula.

The schedule assessment technique was developed using historical cost/schedule performance data.

Creating a foundation for a synergistic approach to program management

NASA Technical Reports Server (NTRS)

Knoll, Karyn T.

1992-01-01

In order to accelerate the movement of humans into space within reasonable budgetary constraints, NASA must develop an organizational structure that will allow the agency to efficiently use all the resources it has available for the development of any program the nation decides to undertake. This work considers the entire set of tasks involved in the successful development of any program. Areas that hold the greatest promise of accelerating programmatic development and/or increasing the efficiency of the use of available resources by being dealt with in a centralized manner rather than being handled by each program individually are identified. Using this information, an agency organizational structure is developed that will allow NASA to promote interprogram synergisms. In order for NASA to efficiently manage its programs in a manner that will allow programs to benefit from one another and thereby accelerate the movement of humans into space, several steps must be taken. First, NASA must develop an organizational structure that will allow potential interprogram synergisms to be identified and promoted. Key features of the organizational structure are recommended in this paper. Second, NASA must begin to develop the requirements for a program in a manner that will promote overall space program goals rather than achieving only the goals that apply to the program for which the requirements are being developed. Finally, NASA must consider organizing the agency around the functions required to support NASA's goals and objectives rather than around geographic locations.

The initial stage of creating the program, which can be deemed as successfully functioning, has been completed. The next stage entails further improvement of the program in order to create conditions for its sustainability and steady improvement. The educational program sustainability plan contains a number of steps, including the following: - Analysis of the status, standards and prospects for development of nuclear security educational programsmore » in the world; - Analysis of the current educational program, level of its functionality and the demand for the program as well as its capability to react adequately to external influences; - Analysis of the factors influencing program development at its current stage and in the future; - Assessment of needs and development of proposals for the program’s sustainability; - Assessment of needs and development of proposals for improving quality and increasing the demand for the program by potential employers; - Assessment of needs and development of proposals for expansion of the program’s content and the scope of its application; - Development of short-term and long-term plans for functioning and development. Strategic prospects for development are associated with the transition from MPC&A to a broader range of tasks covered by the specialization in the area of nuclear security.« less

The development and refinement of models of less established and more established high school environmental service-learning programs in Florida

NASA Astrophysics Data System (ADS)

Malikova, Yuliya

2005-07-01

Environmental Service-Learning (Env. S-L) appears to show great promise and practitioners tout its benefits, although there have been fewer than ten studies in this emerging area of environmental education. The overall study purpose was to describe the nature, status, and effects of Grade 9--16 Env. S-L programs in Florida, and develop descriptive models of those programs. The purpose of Phase I was to describe these programs and associated partnerships. Based on Phase I results, the purpose of Phase II was to develop, compare, and refine models for less and more established high school programs. This study involved: (1) defining the population of Florida 9--16 Env. S-L programs (Phase I); (2) developing and administering program surveys (Phase I, quantitative); (3) analyzing Phase I survey data and identifications of options for Phase II (Intermediate stage); (4) designing and implementing methodology for further data collection (Phase II, qualitative); (5) refining and finalizing program models (Phase II, descriptive); and (6) summarizing program data, changes, and comparisons. This study revealed that Env. S-L has been practiced in a variety of ways at the high school and college levels in Florida. There, the number of high school programs, and participating teachers and students has been growing. Among others, major program features include block scheduling, indirect S-L activities, external funding sources, and formal and ongoing community partnerships. Findings based on self-reported program assessment results indicate that S-L has had positive effects on students across Furco's S-L outcome domains (i.e., academic achievement/success, school participation/behavior, carrier development, personal development, interpersonal development, ethical/moral development, and development of civic responsibility). Differences existed between less established and more established Env. S-L programs. Less established programs had relatively few participating teachers, courses, projects, community partners, and service sites. Most S-L activities were offered as electives. Lead teachers used reflection to integrate academic learning with service experience to a moderate extent. More established programs had a larger number of participating teachers, courses, projects, community partners, partner representatives, and service sites. Students were consistently engaged in multiple forms of reflection. These teachers also practiced S-L before their exposure to the wider field of S-L.

Pound, Catherine M.; Moreau, Katherine A.; Ward, Natalie; Eady, Kaylee; Writer, Hilary

2015-01-01

Background Research training is essential to the development of well-rounded physicians. Although many pediatric residency programs require residents to complete a research project, it is often challenging to integrate research training into educational programs. Objective We aimed to develop an innovative research program for pediatric residents, called the Scholarly Activity Guidance and Evaluation (SAGE) program. Methods We developed a competency-based program which establishes benchmarks for pediatric residents, while providing ongoing academic mentorship. Results Feedback from residents and their research supervisors about the SAGE program has been positive. Preliminary evaluation data have shown that all final-year residents have met or exceeded program expectations. Conclusions By providing residents with this supportive environment, we hope to influence their academic career paths, increase their research productivity, promote evidence-based practice, and ultimately, positively impact health outcomes.

2015-05-01

The Hartford Gerontological Nursing Leaders (HGNL) formerly known as the Building Academic Geriatric Nursing Capacity Initiative (BAGNC), in conjunction with the National Hartford Centers of Gerontological Nursing Excellence (NHCGNE), developed and executed a peer mentoring program beginning in 2011 to enhance both (a) the experience of newly selected scholars and fellows to the NHCGNE and (b) the ongoing professional development of HGNL members. The purpose of this article is to describe key strategies used to develop and execute the peer mentoring program and to present formative program evaluation. The program was launched in January 2011 with seven peer mentor and mentee matches. In June 2012, the peer mentoring committee solicited feedback on the development of the peer mentoring program and changes were made for the subsequent cohorts. An additional 12 matches were made in the following 2 years (2012 and 2013), for a total of 31 matches to date. We have learned several key lessons from our three cohorts regarding how to structure, implement, and carefully evaluate a peer mentoring program. Informal evaluation of our peer mentoring program noted several challenges for both peer mentors and mentees. Having knowledge of and addressing those challenges may increase the overall quality and effectiveness of peer mentoring programs and, in turn, benefit academic nursing by strengthening the faculty workforce. Findings from development and implementation of a peer mentoring program for gerontological faculty could lead to new and adaptable programs in a variety of clinical and education settings. © 2015 Sigma Theta Tau International.

Office ergonomics programs. A case study of North American corporations.

PubMed

Moore, J S

1997-12-01

Subject matter experts from 13 North American corporations provided detailed descriptions of the historical development and the current components and operations of their office ergonomics programs. Results were summarized across corporations and presented for the following programmatic topics: backgrounds of key people, initial awareness and preliminary needs assessment, program development, program implementation, program monitoring and evaluation, program components, education and training, workstation and job analysis, early identification of cases, case management, and alternate office environments. The subject matter experts also provided comments about the strengths of their programs, their advice to others, and lessons they learned. These observations suggested the need for an office ergonomics program, and possibly other occupational health programs, to fit into a corporation's culture and capitalize on its infrastructure. Most corporations used multidisciplinary task forces or teams to develop their programs. Communication, which included training, awareness, advertising, and feedback, was also an important issue. Flexibility and simplicity were important attributes of these programs. It is hoped that this descriptive information will be helpful to some occupational health managers interested in or concerned about managerial perspectives and skills related to the development and implementation of programs within their own corporations.

Distributional effects of Oportunidades on early child development.

PubMed

Figueroa, José Luis

2014-07-01

The Mexican Oportunidades program is designed to increase human capital through investments in education, health, and nutrition for children in extreme poverty. Although the program is not expressly designed to promote a child's cognitive and non-cognitive development, the set of actions carried out by the program could eventually facilitate improvements in these domains. Previous studies on the Oportunidades program have found little impact on children's cognition but have found positive effects on their non-cognitive development. However, the majority of these studies use the average outcome to measure the impact of the program and thus overlook other "non-average" effects. This paper uses stochastic dominance methods to investigate results beyond the mean by comparing cumulative distributions for both children who are and children who are not aided by the program. Four indicators of cognitive development and one indicator of non-cognitive development are analyzed using a sample of 2595 children aged two to six years. The sample was collected in rural communities in Mexico in 2003 as part of the program evaluation. Similar to previous studies, the program is found to positively influence children's non-cognitive abilities: children enrolled in the program manifest fewer behavioral problems compared with children who are not enrolled. In addition, different program effects are found for girls and boys and for indigenous and non-indigenous children. The ranges where the effect is measured cover a large part of the outcome's distribution, and these ranges include a large proportion of the children in the sample. With regard to cognitive development, only one indicator (short-term memory) shows positive effects. Nevertheless, the results for this indicator demonstrate that children with low values of cognitive development benefit from the program, whereas children with high values do not. Overall, the program has positive effects on child development, especially for the most vulnerable, who are at the bottom of the distribution. Copyright © 2014 Elsevier Ltd. All rights reserved.

1988-01-01

Five federally funded family medicine faculty development programs were site visited from December 1985 to June 1986 to collect from experienced project directors, staff, and faculty their thoughts on training practices and future funding. The sites selected were the Faculty Development Center of Texas in Waco (McLennan County Medical Education and Research Foundation), the National Center for Faculty Development at the University of Miami, and programs at Michigan State University, the University of North Carolina-Chapel Hill, and Duke University. Since the late 1970s these programs have trained 259 fellows and 3,284 other participants. In total, $7,515,350 in federal dollars were spent. A variety of program formats and strategies were used to recruit faculty, and to prepare them in teaching, research, and other skill areas. Interviews (as well as phone conversations and letters) with key personnel at each site resulted in a summary of 30 critical elements identified for effective faculty development. Additionally, respondents made 11 specific recommendations to the Federal Faculty Development Grant Program that concern funding and future programs.

Scala and its multi-threaded model based on actors represent an excellent framework for developing purely reactive agents. This paper presents an early research on extending Scala with declarative programming constructs, which would result in a new agent-oriented programming language suitable for developing more advanced, BDI agent architectures. The main advantage the new language over many other existing solutions for programming BDI agents is a natural and straightforward integration of imperative and declarative programming constructs, fitted under a single development framework.

Zellner Keller, Brigitte; Singh, Nirbhay N; Winton, Alan S W

2014-01-01

A number of cognitive interventions have been developed to enhance cognitive functioning in the growing population of the elderly. We describe the Mindfulness-Based Cognitive Approach for Seniors (MBCAS), a new training program designed especially for seniors. It was conceived in the context of self-development for seniors who wish to enhance their relationship with their inner and outer selves in order to navigate their aging process more easily and fluently. Physical and psychosocial problems related to aging, as well as some temporal issues, were taken into account in developing this program. Unlike clinically oriented mindfulness-based programs, which are generally delivered during an 8-week period, the MBCAS training program is presented over a period of 8 months. The main objectives of this program are to teach seniors to observe current experiences with nonjudgmental awareness, to identify automatic behaviors or reactions to current experiences that are potentially nonadaptive, and to enhance and reinforce positive coping with typical difficulties that they face in their daily lives. Details of the program development and initial implementation are presented, with suggestions for evaluating the program's effectiveness.

Anticipatory guidance as a principle of faculty development: managing transition and change.

Schor, Nina F; Guillet, Ronnie; McAnarney, Elizabeth R

2011-10-01

Although one cannot anticipate every individual's unique responses to the transitions and changes that regularly occur in academic medicine, a department-wide faculty development program, based on predictable transition points and supporting faculty at all levels, can minimize such negative responses to change as stress and burnout. In 2007, the authors implemented a new, formal faculty development program in the pediatrics department built on the principle of anticipatory guidance, defined as providing guidance in anticipation of future academic events. The primary components of the program are mentoring committees for individual junior faculty, group leadership development and teaching forums for midlevel faculty, and events that focus on life and career changes for senior faculty. Other department-wide activities augment the program, including review of grant submissions, annual review by a senior faculty committee of the progress of National Institutes of Health mentored research (K-) awardees, women faculty luncheons, and discussions about faculty development at regular faculty meetings. The department's faculty also participate in the University of Rochester Medical Center's active faculty development program. Feedback on the faculty development program has been constructive and mainly positive and will serve to guide the continuing evolution of the program.

Sawyer, J. C., Jr.

1993-01-01

The activities of the joint NASA/DOE/DOD Nuclear Propulsion Program Technical Panels have been used as the basis for the current development of safety policies and requirements for the Space Exploration Initiatives (SEI) Nuclear Propulsion Technology development program. The Safety Division of the NASA Office of Safety and Mission Quality has initiated efforts to develop policies for the safe use of nuclear propulsion in space through involvement in the joint agency Nuclear Safety Policy Working Group (NSPWG), encouraged expansion of the initial policy development into proposed programmatic requirements, and suggested further expansion into the overall risk assessment and risk management process for the NASA Exploration Program. Similar efforts are underway within the Department of Energy to ensure the safe development and testing of nuclear propulsion systems on Earth. This paper describes the NASA safety policy related to requirements for the design of systems that may operate where Earth re-entry is a possibility. The expected plan of action is to support and oversee activities related to the technology development of nuclear propulsion in space, and support the overall safety and risk management program being developed for the NASA Exploration Program.

Community-based programs to address physical activity and diet are seen as a valuable strategy to reduce risk factors for chronic disease. Community partnerships are important for successful local implementation of these programs but little is published to describe the challenges of developing partnerships to implement health promotion programs. The aim of this study was to explore the experiences and opinions of key stakeholders on the development and maintenance of partnerships during their implementation of the HEAL™ program. Semi-structured interviews with key stakeholders involved in implementation of HEAL™ in four local government areas. The interviews were transcribed verbatim and analysed thematically. Partnerships were vital to the success of the local implementation. Successful partnerships occurred where the program met the needs of the partnering organisation, or could be adapted to do so. Partnerships took time to develop and were often dependent on key people. Partnering with organisations that had a strong influence in the community could strengthen existing relationships and success. In remote areas partnerships took longer to develop because of fewer opportunities to meet face to face and workforce shortages and this has implications for program funding in these areas. Partnerships are important for the successful implementation of community preventive health programs. They take time to develop, are dependent on the needs of the stakeholders and are facilitated by stable leadership. SO WHAT?: An understanding of the role of partnerships in the implementation of community health programs is important to inform several aspects of program delivery, including flexibility in funding arrangements to allow effective and mutually beneficial partnerships to develop before the implementation phase of the program. It is important that policy makers have an understanding of the time it takes for partnerships to develop and to take this into consideration when programs are funded and implemented in the community.

In a dynamic health care system, strong leadership has never been more important for surgeons. Little is known about how to design and conduct effectively a leadership program specifically for surgeons. We sought to evaluate critically a Leadership Development Program for practicing surgeons by exploring how the program's strengths and weaknesses affected the surgeons' development as physician-leaders. At a large academic institution, we conducted semistructured interviews with 21 surgical faculty members who applied voluntarily, were selected, and completed a newly created Leadership Development Program in December 2012. Interview transcripts underwent qualitative descriptive analysis with thematic coding based on grounded theory. Themes were extracted regarding surgeons' evaluations of the program on their development as physician-leaders. After completing the program, surgeons reported personal improvements in the following 4 areas: self-empowerment to lead, self-awareness, team-building skills, and knowledge in business and leadership. Surgeons felt "more confident about stepping up as a leader" and more aware of "how others view me and my interactions." They described a stronger grasp on "giving feedback" as well as a better understanding of "business/organizational issues." Overall, surgeon-participants reported positive impacts of the program on their day-to-day work activities and general career perspective as well as on their long-term career development plans. Surgeons also recommended areas where the program could potentially be improved. These interviews detailed self-reported improvements in leadership knowledge and capabilities for practicing surgeons who completed a Leadership Development Program. A curriculum designed specifically for surgeons may enable future programs to equip surgeons better for important leadership roles in a complex health care environment. Copyright © 2016 Elsevier Inc.

Structured Abstract Background In a dynamic healthcare system, strong leadership has never been more important for surgeons. Little is known about how to effectively design and conduct a leadership program specifically for surgeons. We sought to critically evaluate a Leadership Development Program for practicing surgeons by exploring the strengths and weaknesses of program components on surgeons’ development as physician-leaders. Methods At a large academic institution, we conducted semi-structured interviews with 21 surgical faculty members who voluntarily applied, were selected, and completed a newly-created Leadership Development Program in December 2012. Interview transcripts underwent qualitative descriptive analysis with thematic coding based on grounded theory. Themes were extracted regarding surgeons’ evaluations of the program on their development as physician-leaders. Results After completing the program, surgeons reported personal improvements in the following 4 areas: self-empowerment to lead, self-awareness, team-building skills, and business and leadership knowledge. Surgeons felt “more confident about stepping up as a leader” and more aware about “how others view me and my interactions.” They described a stronger grasp on “giving feedback” as well as “business/organizational issues.” Overall, surgeon participants reported positive impacts of the program on their day-to-day work activities, general career perspective, as well as their long-term career development plans. Surgeons also recommended areas for potential improvement for the program. Conclusions These interviews detailed self-reported improvements in leadership knowledge and capabilities for practicing surgeons who completed a Leadership Development Program. A curriculum designed specifically for surgeons may enable future programs to better equip surgeons for important leadership roles in a complex healthcare environment. PMID:27138180

Examining a math-science professional development program for teachers in grades 7-12 in an urban school district in New York State

NASA Astrophysics Data System (ADS)

Kaszczak, Lesia

With the adoption of the Common Core State Standards in New York State and the Next Generation Science Standards, it is more important than ever for school districts to develop professional development programs to provide teachers with the resources that will assist them in incorporating the new standards into their classroom instruction. This study focused on a mathematics and science professional development program known as STEMtastic STEM. The two purposes of the study were: to determine if there is an increase in STEM content knowledge of the participants involved in year two of a three year professional development program and to examine the teachers' perceptions of the impact of the professional development program on classroom instruction. The sample included teachers of grades 7-12 from an urban school district in New York State. The scores of a content knowledge pre-test and post-test were analyzed using a paired sample t-test to determine any significant differences in scores. In order to determine mathematics and science teachers' perceptions of the impact of the professional development program, responses from a 22 item Likert-style survey were analyzed to establish patterns of responses and to determine positive and negative perceptions of participants of the professional development program. A single sample t-test was used to determine if the responses were significantly positive. The results of this study indicated that there was no significant increase in content knowledge as a result of participation in the STEMtastic STEM professional development program. Both mathematics and science teachers exhibited significant positive perceptions of items dealing with hands-on participation during the professional development; support provided by STEMtastic STEM specialists; and the support provided by the administration. It was concluded that both mathematics and science teachers responded positively to the training they received during the professional development sessions, but that their classroom practices did not change as a result of the professional development program.

The goal of the Hui Malama o ke Kai project was the development of a community-based youth program that supported the prevention of youth violence and substance use among 5th- and 6th-grade students from a predominantly Hawaiian community. This program's development included engaging with a variety of community partners and mobilizing parents through the youths' cultural development. Recommendations for working with Hawaiians and other indigenous peoples include having program evaluators work more intimately with program participants and developing program components that address ethnic identity and family engagement. In doing so, youth programs with indigenous peoples can also galvanize small communities that are coping with destructive social concerns.

The study showed that the Geothermal Loan Guaranty Program has had only a negligible effect on geothermal development and the response to the program was far less than expected. The streamlining of environmental regulations and leasing policies, and the granting of intangible drilling cost write-offs and depletion allowances to operators would have had a greater impact on geothermal energy development. The loan guaranty program did not promote the undertaking of any new projects that would not have been undertaken without it. The program only accelerated the pace for some development which might have commenced in the future.

2018-01-01

The Astronomy Department and McDonald Observatory at the University of Texas at Austin has and continues to offer a suite of different astronomy based K-12 teacher professional development programs. One of our longest running, and most successful programs, is reaching its 20th anniversary, the EXES Teacher Associate Program, which was started in 1998. The EXES Teacher Associate program features sustained and continued professional development opportunities for K-12 science and math educators. It consists of 6 times per year day-long meetings, coupled with other professional development opportunities provided at various times. In total, there are approximately 30 active members of the group currently, but more than 90 teachers have participated in this group over its 20 year history. The program has had astronomy education as its focus throughout its history, but different partnerships and collaborations with other programs have supported the group and have allowed for a variety of professional development opportunities and themes for educators to engage in. We will give an overview of this program, present evaluation data and teacher feedback related to program success and student impact, and highlight a few specific program opportunities that are unique and have been shown to be most impactful for participants.

Using business plan development as a capstone project for MPH programs in Canada: validation through the student perspective.

PubMed

Papadopoulos, Andrew; Britten, Nicole; Hatcher, Meghan; Rainville, Keira

2013-10-01

Master of Public Health (MPH) programs have been developed across Canada as a response to the need for adequately trained individuals to work in the public health sector. Educational institutions that deliver MPH programs have a responsibility to ensure that graduates of their program have the essential knowledge, skills and attitudes to begin a successful career in public health. The Public Health Agency of Canada has created the core competencies for public health to guide the development, delivery and evaluation of MPH programs. In Canada, a capstone project is the recommended method of evaluating the MPH graduate's ability to demonstrate proficiency in the public health core competencies. A business plan that develops the framework for a public health program is an ideal capstone project currently used in practice within the University of Guelph MPH program. This group assignment incorporates all 36 of the public health core competencies while providing students with a real-world public health experience, and should be considered for inclusion within MPH programs across Canada. Business planning provides students the opportunity to engage in practice-based learning, applying theoretical knowledge to practice. Further, the ability to develop realistic but financially feasible public health problems is an invaluable skill for MPH graduates. As the development of programs becomes more restricted and the continuation of other programs are under constant threat, the ability to develop a sound business plan is a required skill for individuals entering the public health sector, and will ensure students are able to maximize outcomes given tight fiscal budgets and limited resources.

Evaluating a physician leadership development program - a mixed methods approach.

PubMed

Throgmorton, Cheryl; Mitchell, Trey; Morley, Tom; Snyder, Marijo

2016-05-16

Purpose - With the extent of change in healthcare today, organizations need strong physician leaders. To compensate for the lack of physician leadership education, many organizations are sending physicians to external leadership programs or developing in-house leadership programs targeted specifically to physicians. The purpose of this paper is to outline the evaluation strategy and outcomes of the inaugural year of a Physician Leadership Academy (PLA) developed and implemented at a Michigan-based regional healthcare system. Design/methodology/approach - The authors applied the theoretical framework of Kirkpatrick's four levels of evaluation and used surveys, observations, activity tracking, and interviews to evaluate the program outcomes. The authors applied grounded theory techniques to the interview data. Findings - The program met targeted outcomes across all four levels of evaluation. Interview themes focused on the significance of increasing self-awareness, building relationships, applying new skills, and building confidence. Research limitations/implications - While only one example, this study illustrates the importance of developing the evaluation strategy as part of the program design. Qualitative research methods, often lacking from learning evaluation design, uncover rich themes of impact. The study supports how a PLA program can enhance physician learning, engagement, and relationship building throughout and after the program. Physician leaders' partnership with organization development and learning professionals yield results with impact to individuals, groups, and the organization. Originality/value - Few studies provide an in-depth review of evaluation methods and outcomes of physician leadership development programs. Healthcare organizations seeking to develop similar in-house programs may benefit applying the evaluation strategy outlined in this study.

Given that patient safety measures are increasingly used for public reporting and pay-for performance, it is important for stakeholders to understand how to use these measures for improvement. The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSIs) are one particularly visible set of measures that are now used primarily for public reporting and pay-for-performance among both private sector and Veterans Health Administration (VA) hospitals. This trend generates a strong need for stakeholders to understand how to interpret and use the PSIs for quality improvement (QI). The goal of this study was to develop an educational program and tailor it to stakeholders' needs. In this paper, we share what we learned from this program development process. Our study population included key VA stakeholders involved in reviewing performance reports and prioritizing and initiating quality/safety initiatives. A pre-program formative evaluation through telephone interviews and web-based surveys assessed stakeholders' educational needs/interests. Findings from the formative evaluation led to development and implementation of a cyberseminar-based program, which we tailored to stakeholders' needs/interests. A post-program survey evaluated program participants' perceptions about the PSI educational program. Interview data confirmed that the concepts we had developed for the interviews could be used for the survey. Survey results informed us on what program delivery mode and content topics were of high interest. Six cyberseminars were developed-three of which focused on two content areas that were noted of greatest interest: learning how to use PSIs for monitoring trends and understanding how to interpret PSIs. We also used snapshots of VA PSI reports so that participants could directly apply learnings. Although initial interest in the program was high, actual attendance was low. However, post-program survey results indicated that perceptions about the program were positive. Conducting a formative evaluation was a highly important process in program development. The useful information that we collected through the interviews and surveys allowed us to tailor the program to stakeholders' needs and interests. Our experiences, particularly with the formative evaluation process, yielded valuable lessons that can guide others when developing and implementing similar educational programs.

Need for closer interaction between Space Science Education and Exploration programs in Developing Countries

NASA Astrophysics Data System (ADS)

Singh, R. N.

Space science has become a subject of prime interest. Important issue is the involvement of major expenditures. For overcoming this problem a global co-operation has developed and is proving to be successful. Space programs in developing countries have not yet started in the true sense. India is very well known as one of the pioneering countries for its contribution to upper atmospheric research that was initiated and grew on University campuses. With the advent of space research, the rocket launching facilities were developed and it was used by various scientists groups from many countries. India has developed capability of rocket and satellite launching. With development of space commission, the ground-based study programs spread all over India have decayed slowly. The space research programs are run by governmental agencies only. Universities that initiated space research programs using ground-based radio waves are out of business. Space research has not yet entered the teaching curricula in Indian Universities. It is high time that the teaching and laboratory work in space research be initiated in Indian universities. Development of such a system is emphasized. Its development would enable university's scientists to participate in Indian space research programs on equal footing as commonly seen in American, European, Russian and Japanese programs.

Development and alumni assessment of an interdisciplinary PhD program offered through a blended learning environment.

PubMed

Goldberg, Debora Goetz; Clement, Dolores G; Cotter, J James

2011-01-01

There is a growing need for doctoral-prepared allied health professionals in health care practice, research, and teaching. This paper describes the development and evolution of the PhD Program in Health Related Sciences at Virginia Commonwealth University, which was designed to meet the demand for flexible learning environments by working allied health professionals. The program, now on its 14th year, offers interdisciplinary education in allied health fields through a blended learning environment that includes online and on-site education. An alumni assessment of the program was conducted in 2006 and 2008 to understand how well the program trained its graduates and how well the program responded to the needs of students. Six primary areas were reviewed: 1) extent to which program goals were achieved, 2) general skills and knowledge development for the student, 3) adequacy of the advising function of the program, 4) specific skill development for the student, 5) adequacy of instructional technology, and 6) impressions of the overall program. Findings from the alumni assessment led to changes in curriculum, enhanced use of distance education teaching, additional instructor training on distance-based multimedia technologies, and enhanced student-faculty interaction. Assessment of this program identified key areas, such as technology support, student-student interaction, and student-instructor interaction, which should be emphasized in the development or redesign of allied health educational programs offered in blended learning formats.

The Father Friendly Initiative within Families: Using a logic model to develop program theory for a father support program.

PubMed

Gervais, Christine; de Montigny, Francine; Lacharité, Carl; Dubeau, Diane

2015-10-01

The transition to fatherhood, with its numerous challenges, has been well documented. Likewise, fathers' relationships with health and social services have also begun to be explored. Yet despite the problems fathers experience in interactions with healthcare services, few programs have been developed for them. To explain this, some authors point to the difficulty practitioners encounter in developing and structuring the theory of programs they are trying to create to promote and support father involvement (Savaya, R., & Waysman, M. (2005). Administration in Social Work, 29(2), 85), even when such theory is key to a program's effectiveness (Chen, H.-T. (2005). Practical program evaluation. Thousand Oaks, CA: Sage Publications). The objective of the present paper is to present a tool, the logic model, to bridge this gap and to equip practitioners for structuring program theory. This paper addresses two questions: (1) What would be a useful instrument for structuring the development of program theory in interventions for fathers? (2) How would the concepts of a father involvement program best be organized? The case of the Father Friendly Initiative within Families (FFIF) program is used to present and illustrate six simple steps for developing a logic model that are based on program theory and demonstrate its relevance.

Substance abuse prevention program content: systematizing the classification of what programs target for change.

PubMed

Hansen, William B; Dusenbury, Linda; Bishop, Dana; Derzon, James H

2007-06-01

We conducted an analysis of programs listed on the National Registry of Effective Programs and Practices as of 2003. This analysis focused on programs that addressed substance abuse prevention from among those on the effective or model program lists and that had manuals. A total of 48 programs met these inclusion criteria. We coded program manuals for content that was covered based on how much time was devoted to changing targeted mediating variables. The value of this approach is that program content can be judged using an impartial standard that can be applied to a wide range of intervention approaches. On average, programs addressed eight of 23 possible content areas. Our analyses suggested there were seven distinguishable approaches that have been used in substance abuse prevention programs. These include (i) changing access within the environment, (ii) promoting the development of personal and social skills, (iii) promoting positive affiliation, (iv) addressing social influences, (v) providing social support and helping participants develop goals and alternatives, (vi) developing positive schools and (vii) enhancing motivation to avoid substance use. We propose that the field use such analyses as the basis of future theory development.

A Systematic Review of Life Skill Development Through Sports Programs Serving Socially Vulnerable Youth.

Hermens, Niels; Super, Sabina; Verkooijen, Kirsten T; Koelen, Maria A

2017-12-01

Despite the strong belief in sports programs as a setting in which socially vulnerable youth can develop life skills, no overview exists of life skill development in sports programs serving this youth group. Therefore, the present systematic review provides an overview of the evidence on life skill development in sports programs serving socially vulnerable youth and, insofar as it was investigated in the included studies, of the conditions conducive to life skill development in these sports programs. Potentially relevant studies published during 1990 to 2014 were identified by a search in 7 electronic databases. The search combined terms relating to (a) sport, (b) youth AND socially vulnerable, and (c) life skills. Eighteen of the 2,076 unique studies met the inclusion criteria. Each included study reported that at least 1 life skill improved in youth who participated in the studied sports program. Improvements in cognitive and social life skills were more frequently reported than were improvements in emotional life skills. Only a few of the included studies investigated the conditions in the studied sports programs that made these programs conducive to life skill development. Sports programs have the potential to make a difference in the life skill development of socially vulnerable youth. This conclusion needs to be treated with some caution, because the studies experienced many challenges in reducing the risk for bias. Several alternative research strategies are suggested for future studies in this field.

Status review of NASA programs for reducing aircraft gas turbine engine emissions

Rudey, R. A.

1976-01-01

The paper describes and discusses the results from some of the research and development programs for reducing aircraft gas turbine engine emissions. Although the paper concentrates on NASA programs only, work supported by other U.S. government agencies and industry has provided considerable data on low emission advanced technology for aircraft gas turbine engine combustors. The results from the two major NASA technology development programs, the ECCP (Experimental Clean Combustor Program) and the PRTP (Pollution Reduction Technology Program), are presented and compared with the requirements of the 1979 U.S. EPA standards. Emission reduction techniques currently being evaluated in these programs are described along with the results and a qualitative assessment of development difficulty.

Test-driven programming

NASA Astrophysics Data System (ADS)

Georgiev, Bozhidar; Georgieva, Adriana

2013-12-01

In this paper, are presented some possibilities concerning the implementation of a test-driven development as a programming method. Here is offered a different point of view for creation of advanced programming techniques (build tests before programming source with all necessary software tools and modules respectively). Therefore, this nontraditional approach for easier programmer's work through building tests at first is preferable way of software development. This approach allows comparatively simple programming (applied with different object-oriented programming languages as for example JAVA, XML, PYTHON etc.). It is predictable way to develop software tools and to provide help about creating better software that is also easier to maintain. Test-driven programming is able to replace more complicated casual paradigms, used by many programmers.

2018-01-01

A survey of 345 volunteer water monitoring programs in the United States was conducted to document their characteristics, and perceived level of support for data to inform natural resource management or policy decisions. The response rate of 86% provided information from 46 states. Programs represented a range of ages, budgets, objectives, scopes, and level of quality assurance, which influenced data uses and perceived support by sponsoring agency administrators and external decision makers. Most programs focused on rivers, streams, and lakes. Programs had not made substantial progress to develop EPA or state-approved quality assurance plans since 1998, with only 48% reporting such plans. Program coordinators reported feeling slightly more support for data to be used for management as compared to policy decisions. Programs with smaller budgets may be at particular risk of being perceived to lack credibility due to failure to develop quality assurance plans. Over half of programs identified as collaborative, in that volunteers assisted scientists in program design, data analysis and/or dissemination of results. Just under a third were contributory, in which volunteers primarily collected data in a scientist-defined program. Recommendations to improve perceived data credibility, and to augment limited budgets include developing quality assurance plans and gaining agency approval, and developing partnerships with other organizations conducting monitoring in the area to share resources and knowledge. Funding agencies should support development of quality assurance plans to help ensure data credibility. Service providers can aid in plan development by providing training to program staff over time to address high staff turnover rates.

Bryant, Ashley Leak; Brody, Ab; Perez, Adriana; Shillam, Casey; Edelman, Linda S.; Bond, Stewart M.; Foster, Victoria; Siegel, Elena

2016-01-01

Purpose In conjunction with the National Hartford Centers of Gerontological Nursing Excellence (NHCGNE), formerly known as the Building Academic Geriatric Nursing Capacity Initiative (BAGNC), the Hartford Gerontological Nursing Leaders (HGNL) developed and executed a program beginning in 2011 to enhance both (a) the experience of newly selected scholars and fellows to the NHCGNE and (b) the ongoing professional development of the HGNL. The purpose of this article is to describe key strategies used to develop and execute the mentoring program and to present the formative and summative program evaluation. Design The program was launched in January 2011 with seven peer mentor and mentee matches. In June 2012, the peer mentoring committee solicited feedback on the development of the peer mentoring program and changes were made for the subsequent cohorts. Findings An additional 12 matches were made in the following 2 years (2012 and 2013), for a total of 31 matches to date. We have learned several key lessons from our three cohorts regarding how to structure, implement, and carefully evaluate a peer mentoring program. Conclusions Informal evaluation of our peer mentoring program noted several challenges for both peer mentors and mentees. Having knowledge of and addressing those challenges may increase the overall quality and effectiveness of peer mentoring programs and, in turn, benefit academic nursing by strengthening the faculty workforce. Clinical Relevance Findings from development and implementation of a peer mentoring program for gerontological faculty could lead to new and adaptable programs in a variety of clinical and education settings.
