Racial/ethnic differences in the use of psychotropic medication in high-risk children and adolescents.

OBJECTIVES To investigate rates of psychotropic medication use by youths served in public service sectors as a function of race/ethnicity. METHOD Logistic regression models were used to examine racial/ethnic differences in caregiver report of psychotropic medication use for a random stratified sample of 1,342 children who were served in public service sectors during the second half of fiscal year 1996-97. RESULTS Race/ethnicity predicted caregiver report of past-year and lifetime psychotropic medication use when all other factors were held constant. Specifically, caregivers of African-American and Latino children were less likely to report past-year use compared to white children; caregivers of Latino children and "others" were less likely to report lifetime use. Additional factors predictive of medication use in regression models included younger age, male gender, higher household income, insurance type, active to mental health sector at time of enumeration into the study, impairment and diagnosis of mood, and anxiety or attentional disorder. CONCLUSIONS Racial/ethnic differences in use of psychotropic medication occur in children served in public service sectors and need to be considered in clinical diagnosis and treatment.
Associations of Truancy, Perceived School Performance, and Mental Health With Alcohol Consumption Among Adolescents.

BACKGROUND This study examined associations of truancy, perceived school performance, and mental health with adolescents' week, weekend, and binge drinking. METHODS A cross-sectional study was conducted among 1167 secondary school students of Dutch ethnicity (mean age, 15.9 years, SD = 0.69). Alcohol consumption, truancy, perceived school performance, and mental health status were assessed with self-report questionnaires. Ordinal regression analyses were performed to assess the associations. RESULTS Truancy (odds ratio [OR] = 2.53; 95% confidence interval [CI], 1.70-3.77) and poorer mental health (OR = 1.04; 95% CI, 1.02-1.07) were associated with binge drinking more often. Truancy (OR = 1.89; 95% CI, 1.14-3.16) and poorer mental health (OR = 1.06; 95% CI, 1.02-1.09) were also associated with drinking (more) alcohol on week days. Furthermore, truancy (OR = 2.60; 95% CI, 1.76-3.83) and having an average (OR = 1.81; 95% CI, 1.19-2.77) or less than average (OR = 3.65; 95% CI, 1.93-6.90) perceived school performance were associated with drinking (more) alcohol on the weekend. CONCLUSIONS Findings of this study suggest that adolescents who are truant and/or have a poor mental health status are at increased risk of binge and week drinking. Furthermore, adolescents who are truant and/or have an average or less than average perceived school performance are at increased risk of weekend drinking.
Role of Nuclear Ca2+/Calmodulin-Stimulated Phosphodiesterase 1A in Vascular Smooth Muscle Cell Growth and Survival

In response to biological and mechanical injury, or in vitro culturing, vascular smooth muscle cells (VSMCs) undergo phenotypic modulation from a differentiated “contractile” phenotype to a dedifferentiated “synthetic” one. This results in the capacity to proliferate, migrate, and produce extracellular matrix proteins, thus contributing to neointimal formation. Cyclic nucleotide phosphodiesterases (PDEs), by hydrolyzing cAMP or cGMP, are critical in the homeostasis of cyclic nucleotides that regulate VSMC growth. Here, we demonstrate that PDE1A, a Ca2+-calmodulin–stimulated PDE preferentially hydrolyzing cGMP, is predominantly cytoplasmic in medial “contractile” VSMCs but is nuclear in neointimal “synthetic” VSMCs. Using primary VSMCs, we show that cytoplasmic and nuclear PDE1A were associated with a contractile marker (SM-calponin) and a growth marker (Ki-67), respectively. This suggests that cytoplasmic PDE1A is associated with the “contractile” phenotype, whereas nuclear PDE1A is with the “synthetic” phenotype. To determine the role of nuclear PDE1A, we examined the effects loss-of-PDE1A function on subcultured VSMC growth and survival using PDE1A RNA interference and pharmacological inhibition. Reducing PDE1A function significantly attenuated VSMC growth by decreasing proliferation via G1 arrest and inducing apoptosis. Inhibiting PDE1A also led to intracellular cGMP elevation, p27Kip1 upregulation, cyclin D1 downregulation, and p53 activation. We further demonstrated that in subcultured VSMCs redifferentiated by growth on collagen gels, cytoplasmic PDE1A regulates myosin light chain phosphorylation with little effect on apoptosis, whereas inhibiting nuclear PDE1A has the opposite effects. These suggest that nuclear PDE1A is important in VSMC growth and survival and may contribute to the neointima formation in atherosclerosis and restenosis.
Acute generalized exanthematous pustulosis. Analysis of 63 cases.

We retrospectively analyzed 63 observations collected in nine French departments of dermatology of an acute pustular dermatosis, recently named in the French literature acute generalized exanthematous pustulosis (AGEP). Even though 11 of these cases occurred in patients with a history of psoriasis, AGEP appeared distinct from pustular psoriasis based on several slight pathologic differences, drug induction in most cases, and a more acute course of fever and pustulosis, with rapid spontaneous healing. We, therefore, suggest that AGEP is a reaction pattern, perhaps favored by a "psoriatic background. " The most frequent causes of AGEP seem to be drug reactions, acute infections with enteroviruses, and hypersensitivity to mercury. With 55 (87%) of 63 cases attributed to drugs in this series, AGEP should be added to the list of cutaneous adverse drug reactions. Among drug-induced skin eruptions, AGEP is remarkable by its short time to onset after the administration of the suspected drug (less than 24 hours in half of our cases) and the great predominance (80%) of antibiotics as causative agents. It is suggested that some cases previously reported as "drug-induced pustular psoriasis" were in fact AGEP.
OsYSL6 Is Involved in the Detoxification of Excess Manganese in Rice1[W][OA]

Yellow Stripe-Like (YSL) proteins belong to the oligopeptide transporter family and have been implicated in metal transport and homeostasis in different plant species. Here, we functionally characterized a rice (Oryza sativa) YSL member, OsYSL6. Knockout of OsYSL6 resulted in decreased growth of both roots and shoots only in the high-manganese (Mn) condition. There was no difference in the concentration of total Mn and other essential metals between the wild-type rice and the knockout line, but the knockout line showed a higher Mn concentration in the leaf apoplastic solution and a lower Mn concentration in the symplastic solution than wild-type rice. OsYSL6 was constitutively expressed in both the shoots and roots, and the expression level was not affected by either deficiency or toxicity of various metals. Furthermore, the expression level increased with leaf age. Analysis with OsYSL6 promoter-green fluorescent protein transgenic rice revealed that OsYSL6 was expressed in all cells of both the roots and shoots. Heterogolous expression of OsYSL6 in yeast showed transport activity for the Mn-nicotianamine complex but not for the Mn-mugineic acid complex. Taken together, our results suggest that OsYSL6 is a Mn-nicotianamine transporter that is required for the detoxification of excess Mn in rice.
A subthreshold persistent sodium current mediates bursting in rat subfornical organ neurones

1 It is widely accepted that while release of amino acid neurotransmitters occurs with relatively high fidelity, peptidergic synapses require clustered bursts of action potentials for optimal transmitter release. Here we describe for the first time the occurrence and mechanisms of bursting by neurones in the subfornical organ (SFO), cells that utilize the peptide angiotensin II (ANG) in neurotransmission in autonomic pathways. 2 In current clamp recording of isolated SFO neurones in vitro, 53 % (n= 74) showed either spontaneous or evoked burst‐like discharge patterns. Bursts typically appeared as shifts in bistable membrane potential, with action potentials superimposed on a depolarizing afterpotential (DAP). Similarly, in vivo single unit recordings of identified SFO neurones showed that 9 of 15 neurones fired in bursts. 3 The pattern of bursting, as well as duration of evoked DAPs was strongly dependent upon membrane potential, suggesting that the DAP contributes to burst generation. Based on our previous observation of calcium‐sensing receptor (CaR)‐activated bursts, we investigated the effects of NPS R‐467, an allosteric agonist of the CaR, on evoked DAPs. NPS R‐467 (1 μM) potentiated DAP duration throughout the voltage range tested. 4 We observed a dependence of evoked DAPs upon Na+ channels, as shown by sensitivity to tetrodotoxin (0.5 μM) or reduction of external [Na+] from 140 to 40 |mM. The duration of DAPs suggested that a persistent Na+ current mediates these events. Voltage‐clamp analysis revealed the presence of a subthreshold sodium current, INaP. 5 Pharmacological blockade of INaP with 100 μM lidocaine reduced the duration of evoked DAPs, and inhibited bursting in SFO neurones. Facilitation of INaP with 10 nM anemone toxin (ATX) increased DAP duration and led to marked excitation of bursting cells. These data indicate that INaP is the main current underlying bursting in SFO neurones. 6 Our observations of receptor‐mediated facilitation of bursting by SFO neurones represents an intriguing mechanism through which the release of the peptide neurotransmitter ANG may be regulated.
Action recognition from a different view

In this paper, we propose a novel approach to recognise human activities from a different view. Although appearance-based recognition methods have been shown to be unsuitable for action recognition for varying views, there must be some regularity among the same action sequences of different views. Self-similarity matrices appear to be relative stable across views. However, the ability to effectively realise this stability is a problem. In this paper, we extract the shape-flow descriptor as the low-level feature and then choose the same number of key frames from the action sequences. Self-similarity matrices are obtained by computing the similarity between any pair of the key frames. The diagonal features of the similarity matrices are extracted as the highlevel feature representation of the action sequence and Support Vector Machines (SVM) is employed for classification. We test our approach on the IXMAS multi-view data set. The proposed approach is simple but effective when compared with other algorithms.
Control of Neuronal Migration and Aggregation by Reelin Signaling in the Developing Cerebral Cortex

The mammalian cerebral neocortex has a well-organized laminar structure, achieved by the highly coordinated control of neuronal migration. During cortical development, excitatory neurons born near the lateral ventricle migrate radially to reach their final positions to form the cortical plate. During this process, dynamic changes are observed in the morphologies and migration modes, including multipolar migration, locomotion, and terminal translocation, of the newborn neurons. Disruption of these migration processes can result in neuronal disorders such as lissencephaly and periventricular heterotopia. The extracellular protein, Reelin, mainly secreted by the Cajal-Retzius neurons in the marginal zone during development, plays a crucial role in the neuronal migration and neocortical lamination. Reelin signaling, which exerts essential roles in the formation of the layered neocortex, is triggered by the binding of Reelin to its receptors, ApoER2 and VLDLR, followed by phosphorylation of the Dab1 adaptor protein. Accumulating evidence suggests that Reelin signaling controls multiple steps of neuronal migration, including the transition from multipolar to bipolar neurons, terminal translocation, and termination of migration beneath the marginal zone. In addition, it has been shown that ectopically expressed Reelin can cause neuronal aggregation via an N-cadherin-mediated manner. This review attempts to summarize our knowledge of the roles played by Reelin in neuronal migration and the underlying mechanisms.
Impact of the Union Budget on the Indian Stock Market

The stock market of a country is said to act as a barometer of its economic health. All economic activities happening in the country and outside the country lead to a change in the market conditions. Different market players who invest their money in stocks are not only interested to know about the rise and fall in the stock market, they are keen to know about the various economic events / activities that are going to take place in the near future. The stock market reacts depending on how the investors interpret the economic activities. The Union Budget is perhaps the most watched event in economic policy making in India. The core fiscal issues - taxation, expenditures, and the fiscal deficit - are obviously important for macroeconomics. In addition, governments have often chosen to use the Budget speech as a mechanism for announcing important new policy initiatives, and for outlining some plans for economic policy in the coming months. The stock market response to a Budget is often viewed as an important summary statistic of the 'quality' of a Budget in terms of improving the macroeconomic prospects. In this research paper, I intended to find an interplay between the Budget and the stock market, in the areas like informational efficiency and implications for portfolios and trading. In this study, the main focus is on return and volatility impact along with different event windows.
A State-of-the-Art Review on the Integration of Building Information Modeling (BIM) and Geographic Information System (GIS)

The integration of Building Information Modeling (BIM) and Geographic Information System (GIS) has been identified as a promising but challenging topic to transform information towards the generation of knowledge and intelligence. Achievement of integrating these two concepts and enabling technologies will have a significant impact on solving problems in the civil, building and infrastructure sectors. However, since GIS and BIM were originally developed for different purposes, numerous challenges are being encountered for the integration. To better understand these two different domains, this paper reviews the development and dissimilarities of GIS and BIM, the existing integration methods, and investigates their potential in various applications. This study shows that the integration methods are developed for various reasons and aim to solve different problems. The parameters influencing the choice can be summarized and named as “EEEF” criteria: effectiveness, extensibility, effort, and flexibility. Compared with other methods, semantic web technologies provide a promising and generalized integration solution. However, the biggest challenges of this method are the large efforts required at early stage and the isolated development of ontologies within one particular domain. The isolation problem also applies to other methods. Therefore, openness is the key of the success of BIM and GIS integration.
Fuzzy control for fuzzy interval systems part II: application to inverse model based control

This part aims at designing a fuzzy inverse controller for fuzzy linear interval systems. The controller is designed from the fuzzy interval ranges of the system parameters. Indeed, for a given degree of confidence on the fuzzy system parameters, the control objective can be viewed as maintaining the system output within a tolerance envelope, around the exact trajectory, specified by a degree of preference on the fuzzy trajectory. The validity of the proposed method is illustrated by simulation examples.
Optimal Pricing and Order-Up-To S Inventory Policy with Expected Utility of the Present Value Criterion

The article determines pricing and order-up-to level S inventory decisions over an infinite planning horizon from the point of view of a risk-averse decision maker. The demand is assumed to be stochastic but influenced by the selling price which is a decision variable. Shortages are allowed and backordered partially. We calculate the present value of the cash flow over the entire planning horizon and incorporate the notion of risk aversion into the model using a concave utility function. We numerically demonstrate the model and investigate the impact of different model-parameters on the optimal decisions. It is observed that the optimal selling price for a risk-averse decision maker is not less than the optimal selling price of a risk-neutral decision maker while the optimal order level for the risk-averse decision maker is always less than that of the risk-neutral decision maker.
Early diagnosis and treatment monitoring roles of tumor markers Cyfra 21‐1 and TPS in oral squamous cell carcinoma

Mucosal oral squamous cell carcinoma (SCC) accounts for 3–5% of all reported cancers, with a 5‐year survival rate of approximately 50%. Unfortunately, current detection means are of no value in diagnosing lesions early enough for cure, especially when they recur after resection. Postoperative radiotherapy and/or covering the resection site with reconstructive flaps (regional or free vascularized) often makes early diagnosis an impossible task.
Prevalence of Safer Needle Devices and Factors Associated with Their Adoption: Results of a National Hospital Survey

Objectives. In this study, we collected and analyzed the first data available on the extent of the adoption of safer needle devices (engineered sharps injury protections [ESIPs]) by U.S. hospitals and on the degree to which selected factors influence the use of this technology. Methods. We gathered data via a telephone survey of a random sample of 494 U.S. hospitals from November 1999 through February 2000. Results. Although 83% of the sample reported some ESIP adoption, adoption was inconsistent across types of devices. All of the appropriate units in 52% of the facilities had adopted needleless intravenous delivery systems, but the hospitals used other types of ESIPs less often. A respondent's perception that the cost of ESIPs would not be a problem for the hospital was the best predictor of adoption of ESIPs in the facility, explaining 8% of the variance. Other predictors of adoption included the size of the hospital and the presence or absence of state legislative activity on the needlestick issue. Conclusions. Smaller hospitals may require special encouragement and assistance from outside sources to adopt expensive risk-reduction innovations such as ESIPs. Although use of ESIPs is the mandated and preferred way to protect workers from needlesticks, complete adoption of this technology will depend on the support of the social systems in which it is used and the people who use it.
The Analysis of Pine Stumpage Prices Based on Timber Sale Characteristics of the Southern United States

Abstract The stumpage price changes were calculated and analyzed from the data collected by Timber Mart-South from 1998 to 2007. We analyzed the relationship between pine sawtimber stumpage prices and timber sale characteristics using hedonic pricing method. Quadratic transformation was employed for sale size and contract length. Stumpage prices increased with sale size, contract length, bid sales, and the number of bidders. The presence of above average or excellent grade, market conditions, and logging conditions also are positively related to stumpage prices.Key Words: stumpage prices, hedonic pricing method, timber-marth-south, timber sale characteristics Received: February 26, 2014.

Since timber markets basically de-pend on the supply and demand, timber buyers and sellers need up-to-date timber market information such as market trends and trade news. However, it is not an easy task to predict timber price (Mei et al. 2010). Timber market is a function of the relationship between timber and a variety of factors, such as wood consumption, wood supply, pro-duction technology, finished product demand, and stum-page prices, and also the change in timberland ownership may have had a significant influence on timber markets (TMS 2009). Delivered prices include harvesting, trans-portation, and other markups above the stumpage price, and fuel costs and distances to mills will have effect on transportation costs, where wood quality and tract size are the main factors concerning harvest costs (TMS 2009). The hedonic price method is an approach which most commonly uses regression analysis to estimate the implicit values of characteristics from a value of commodity price (Rosen 1974). In the process of manufacturing, some pro-duction inputs could be diverse and have significantly dif-ferent characteristics. In such cases, a hedonic pricing ap-proach is suitably employed for estimating the implicit pri-ces of the various characteristics of an input and the de-mand for the input subsequently (Ladd and Martini 1976). Thus, a hedonic model can be used to explain production factors or the prices of differentiated products. This he-donic price approach has been adapted to timber markets with heterogeneous inputs such as species composition, tree size, volume, and quality based on the assumption that such characteristics affect the lumber production (Puttock et al.
