Traumatic brain injury, executive functioning, and suicidal behavior: a brief report.

OBJECTIVE The aim of this pilot study was to explore the relationship between executive dysfunction and suicidal behavior in two groups of participants: (Group 1, n = 18) veterans with traumatic brain injury (TBI) and a history of at least one suicide attempt (SA), and (Group 2, n = 29) veterans with TBI and no history of SA. Controlling for the severity of TBI, it was hypothesized that participants in Group 1 would perform more poorly than those in Group 2 on measures of executive functioning. DESIGN The primary outcome variable was decision making as assessed by performance on the Iowa Gambling Task (IGT). Secondary outcome variables included laboratory-measured impulsivity as measured by the Immediate and Delayed Memory Test (IMT/DMT), abstract reasoning as measured by the Wisconsin Card Sorting Test (WCST), and aggression as measured by the Lifetime History of Aggression (LHA) scale. RESULTS Among those in Group 1, time between TBI and first suicide attempt postinjury varied widely (months to nearly 30 years). Only the WCST perseverative errors score differed significantly between individuals with and without histories of one or more suicide attempts (SAs). CONCLUSION Suggestions for future study of SA among those with TBI are provided. When working with individuals with TBI, clinicians are encouraged to incorporate suicide risk assessment into their practice. Augmenting this process with a measure of perseveration may be beneficial.
Electrospun Nanofibers‐Mediated On‐Demand Drug Release

A living system has a complex and accurate regulation system with intelligent sensor‐processor‐effector components to enable the release of vital bioactive substances on demand at a specific site and time. Stimuli‐responsive polymers mimic biological systems in a crude way where an external stimulus results in a change in conformation, solubility, or alternation of the hydrophilic/hydrophobic balance, and consequently release of a bioactive substance. Electrospinning is a straightforward and robust method to produce nanofibers with the potential to incorporate drugs in a simple, rapid, and reproducible process. This feature article emphasizes an emerging area using an electrospinning technique to generate biomimetic nanofibers as drug delivery devices that are responsive to different stimuli, such as temperature, pH, light, and electric/magnetic field for controlled release of therapeutic substances. Although at its infancy, the mimicry of these stimuli‐responsive nanofibers to the function of the living systems includes both the fibrous structural feature and bio‐regulation function as an on demand drug release depot. The electrospun nanofibers with extracellular matrix morphology intrinsically guide cellular drug uptake, which will be highly desired to translate the promise of drug delivery for the clinical success.
Induction of acrosomal exocytosis in chicken spermatozoa by inner perivitelline-derived N-linked glycans.

In birds, the ovum is surrounded by a glycoprotein coat known as the inner perivitelline layer (IPVL), which is analogous to the mammalian zona pellucida and, as such, is the site of initial sperm binding and induction of acrosomal exocytosis (the acrosome reaction). In this study, we demonstrate that oligosaccharides isolated from chicken-IPVL glycoproteins are capable of inducing the acrosome reaction in chicken spermatozoa. Preparations containing only O-linked glycans were unable to induce the acrosome reaction whereas N-linked oligosaccharides released from the IPVL by PNGaseF treatment could induce the acrosome reaction. Addition of galactose to terminal N-acetyglucosamine residues suppressed the acrosome reaction-inducing capacity of the oligosaccharide preparation; however, this capacity could be restored by co-incubation with beta-galactosidase. This evidence suggests that the acrosome reaction-inducing factor is probably an N-linked oligosaccharide with terminal N-acetyl-glucosamine residues.

[Poster] Utilizing contact-view as an augmented reality authoring method for printed document annotation

In Augmented Reality (AR) the real world is enhanced by superimposed digital information commonly visualized through augmented annotations. The visualized data comes from many different data sources. One increasingly important source of data is user generated content. Unfortunately, AR tools that support user generated content are not common hence the majority of augmented data within AR applications is not generated utilizing AR technology. In this paper we discuss the main reasons for this and evaluate how the contact-view paradigm could enhance annotation authoring process within the class of tabletop size AR workspaces. This evaluation is based on a prototype that allows musicians to annotate a music score manuscript utilizing freehand drawing on top of device screen. Experimentation showed the potential of contact-view paradigm as an annotation authoring method that performs well in single and collaborative multi-user situations.
Association of attention-deficit/hyperactivity disorder symptoms with levels of cigarette smoking in a community sample of adolescents.

OBJECTIVE Research on the association of attention-deficit/hyperactivity disorder (ADHD) with cigarette smoking has primarily occurred within samples of clinically referred youths. This paper reports the association of ADHD symptoms with smoking practices in a community sample of adolescents. METHOD Confidential self-report surveys were completed by 1,066 tenth-grade students enrolled in five public high schools who were taking part in a longitudinal study of biobehavioral predictors of adolescent smoking adoption. A well-standardized measure of ADHD inattention and hyperactivity-impulsivity symptoms, as well as demographic and social risk factors, were examined in relation to three levels of cigarette smoking: (1) never having smoked, (2) ever having smoked, and (3) current smoking (having smoked a cigarette within the past 30 days). RESULTS Regarding lifetime cigarette use, approximately 43% of students had ever smoked. Among those who had ever smoked, approximately 31% of students were current smokers. Ever having smoked was associated with family (odds ratio [OR] = 2.49, confidence interval [CI] = 1.85, 3.36) and peer smoking (OR = 4.05, CI = 3.07, 5.33) and clinically significant ADHD inattention symptoms (OR = 3.39, CI = 1.53, 7.54). Current smoking was also associated with peer smoking (OR = 2.99, CI = 1.72, 5.20) and clinically significant ADHD inattention symptoms (OR = 2.80, CI = 1.20, 6.56). CONCLUSION Clinically significant ADHD symptoms should be taken into account when identifying adolescents at risk to smoke, since those with problematic inattention may be more likely to experiment with smoking and to become regular tobacco users.
Multiple cancers in the prostate. Morphologic features of clinically recognized versus incidental tumors

Multiple independent tumors were identified in specimens from 117 of 234 prostatectomies for clinical adenocarcinoma; there were 266 incidental cancers in these 117 prostates. The clinically detected carcinoma was the largest (or only) tumor in all 202 Stage B cases. However, among 32 Stage A cases (detection by transurethral resection), there were 8 prostates in which an incidental tumor was larger than the clinically manifest cancer. These were all small tumors except for two incidental cancers with a volume greater than 2 cm3; roughly 80% of incidental carcinomas were smaller than 0.5 cm3, whereas fewer than 20% of manifest tumors were smaller than 0.5 cm3. Comparison with a series of cancers found incidentally at cystoprostatectomy for bladder cancer showed the same volume distribution as incidental (smaller) carcinomas in patients with prostate cancer. This distribution was thought to reflect the volume distribution of prostate cancer in the general population older than 50 years of age. It was concluded that additional incidental tumors are common in patients with prostate cancer, but their sum of volumes is seldom as large as the clinical cancer volume. Cancer 1992; 70:2313‐2318.
An Analytical Yield Model for Zero- $V_{\mathrm {GS}}$ -Load Thin-Film Transistor Logic Circuits

This letter presents an analytical circuit yield model for zero-VGS-load thin-film transistor (TFT) logic circuits, which describes the circuit yield as a function of the circuit complexity, threshold voltage dispersion of TFTs, and circuit design parameters. By comparing the calculation result through the model with that by Monte Carlo statistical circuit simulations, the model is proved to be capable of providing a simple and effective way to predict the yield of a given zero-VGS-load TFT circuit design, and is thus applicable for TFT performance evaluation or device and process optimization.

Effects of isoflavone and counter-resistance training on bone mineral density in postmenopausal women

O estudo teve como objetivo investigar o efeito isolado e combinado do treinamento contrarresistencia (TCR) e da suplementacao de isoflavona da soja (ISO) sobre a densidade mineral ossea (DMO) e a remodelacao ossea em mulheres na pos-menopausa (MPM). Tratou-se de estudo clinico, prospectivo, placebo-controlado, duplo-cego (ISO) e randomizado, envolvendo 80 MPM sedentarias, com idade entre 45-70 anos, randomizadas em quatro grupos (71 completaram nove meses): TCR+ISO (n=15); sem TCR+ISSO (n=20); TCR+ placebo (n=18); sem TCR + placebo (n=18). As participantes randomizadas no grupo ISO receberam 100mg/dia/VO (via oral) de isoflavona e as no grupo TCR realizaram sessoes supervisionadas de exercicios contrarresistencia (minimo de 2 dias/semana). Nos momentos inicial e final do estudo, as DMO do colo do femur e da coluna lombar foram estimadas pela absortometria radiologica de feixes duplos de energia (DXA) e a forca muscular pelo teste de 1-RM. Os valores plasmaticos de telopeptideos carboxiterminais do colageno tipo I (CTX), osteocalcina e fator de crescimento semelhante a insulina (IGF-1) foram dosados como marcadores de remodelacao ossea. Apos 9 meses de intervencao nao foram observados efeitos independentes ou aditivos do TCR e ISSO sobre a DMO bem como sobre os valores de osteocalcina, CTX e IGF-1 (p>0,05). Houve aumento da forca muscular (+ 35,2%) somente nos grupos submetidos ao TCR (p=0,02). Conclui-se que o TCR e ISO nao apresentam efeitos combinados ou independentes sobre a DMO do femur e da coluna lombar e marcadores da remodelacao ossea em MPM apos nove meses de intervencao.
Abnormal exhaled ethane concentrations in scleroderma

Abstract Scleroderma (systemic sclerosis) is a chronic multisystem autoimmune disease in which oxidative stress is suspected to play a role in the pathophysiology. Therefore, it was postulated that patients with scleroderma would have abnormally high breath ethane concentrations, which is a volatile product of free-radical-mediated lipid peroxidation, compared with a group of controls. There was a significant difference (p<0.05) between the mean exhaled ethane concentration of 5.27 pmol ml–1 CO2 (SEM=0.76) in the scleroderma patients (n=36) versus the mean exhaled concentration of 2.72 pmol ml−1 CO2 (SEM=0.71) in a group of healthy controls (n=21). Within the scleroderma group, those subjects taking a calcium channel blocker had lower ethane concentrations compared with patients who were not taking these drugs (p=0.05). There was a significant inverse association between lung diffusion capacity for carbon monoxide (per cent of predicted) and ethane concentration (b=−2.8, p=0.026, CI=−5.2 to −0.35). These data support the presence of increased oxidative stress among patients with scleroderma that is detected by measuring breath ethane concentrations.
Discapacidad y medios de comunicación; entre la información y el estereotipo

La discapacidad ha dado en Espana un paso significativo hacia delante durante la ultima decada. El compromiso de las instituciones, la existencia de una legislacion especifica y la progresiva vertebracion del colectivo a traves de un incipiente movimiento social ha posibilitado la conduccion de sus demandas hasta los circulos donde se producen las tomas de decisiones y su aparicion entre las noticias de actualidad de los distintos medios de comunicacion. La superacion de un formato periodistico caduco para la discapacidad, basado en el estereotipo y faciles generalizaciones, es el gran reto del colectivo en estos momentos en su relacion con los medios.
The weekend e ff ect within and downwind of Sacramento : Part 2 . Observational evidence for chemical and dynamical contributions

Observations of day-of-week patterns and diurnal profiles of ozone, volatile organic compounds and nitrogen oxides are examined to assess the chemical and dynamical factors governing the daytime ozone accumulation and the distribution of chemically related species in Central California. Isoprene observations show that urban OH con5 centrations are higher on the weekend whereas rural OH concentrations are lower on the weekend, confirming that NOx concentrations have a direct effect on the rate of photochemical ozone production and that the transition from NOx-saturated (VOC-limited) to NOx-limited chemistry occurs between the city and the downwind rural counties. We quantify the extent to which mixing of ozone and its precursors from aloft contributes 10 to the daytime accumulation of ozone at the surface in Sacramento. Ozone production in the rural Mountain Counties is currently NOx-limited and will decrease in response to NOx emission reductions in the Sacramento Valley. However, NOx emissions reductions of at least 50% (from weekday levels) are necessary to bring about a significant decrease in accumulation of ozone at the surface in the Sacramento Valley. The im15 pact of NOx emission reductions on the frequency of exceeding the federal 8-hour ozone standard at an individual site will depend on the balance between reduced titration and the sign and magnitude of production changes. We further show that HNO3 production, which depends on the product of OH and NO2 mixing ratios, is a constant at high NOx, suggesting that NOx must be reduced below a threshold before nitrate 20 aerosol can be expected to decrease.
Newly made enzymes determine ongoing cell wall synthesis and the antibacterial effects of cell wall synthesis inhibitors

Cell wall synthesis can continue with less than the total complement of cell wall synthetic enzymes present in normal growing cells. A method was developed to investigate whether there exists an excess of cell wall-synthesizing enzymes (penicillin-binding proteins [PBPs]) which all remain functional or whether a mixed population of functional and nonfunctional enzymes characterize normal cells. Surprisingly, cells in which less than 10% of the PBPs were functional could grow at a normal rate, as evidenced by increases in viable counts, culture turbidity, and rates of peptidoglycan, protein, and RNA synthesis. This subset of functional enzymes was biosynthetically new. Penicillin-induced lysis occurred contingent on the acylation of this same small fraction of PBPs, the copy number and affinities of which were below the level of detection by current fluorographic assay techniques. We propose that PBPs have a short functional half-life and that cell wall synthesis and bacterial lysis reflect the activity of newly synthesized PBPs.
Transversal , Helly and Tverberg type Theorems in Geometry , Combinatorics and Topology III

Helly’s Theorem and its relatives, the theorems of Radon and Caratheodory have played an important role in Discrete and Convex Geometry, there are numerous generalizations and variations of them that have been studied from different perspectives and points of view. The classical lemma of Radon for instance states that any d + 2 points in R can be partitioned into two classes with intersecting convex hulls. This theorem can be rephrased in the following equivalent way: Given any affine map: f : ∆ → R, been ∆ the d + 1 simplex in R there are two disjoint faces σ1 and σ2 of ∆ such that f(σ1) ∩ f(σ2) 6= ∅. During this workshop one of the main philosophical aspects was related with the question of up to what extent this classical theorems really depend on convexity or linearity, i.e., whether or not there are some more fundamental topological principles that underly them For instance topological generalizations of Helly’s theorem, topological generalizations of the classical theorems in discrete and convex geometry of BorosFüredi (d=2) and of Bárány. One of the most beautiful theorems in combinatorial convexity is due to Tverberg, that is the r-partite version of Radon’s Lemma. To be more precise,Tverberg’s theorem states that every (d+1)(r−1)+1 points in Euclidean d-space R can be partitioned into r parts such that the convex hulls of these parts have nonempty intersection. This theorem still remains central and is one of the most intriguing results of combinatorial geometry. It has been shown that there are many close relations between Tverberg’s theorem and several important results in mathematics, such as; Rado’s Central Theorem on general measures, the Ham Sandwich Theorem and the Four Color Theorem, just to mention some examples. The original Tverberg Theorem now has several different proofs, including those by Tverberg, Roudneff, Sarkaria and more recently due to Zvagelśkii. A specially elegant proof is due to Zarkaria with further simplifications of Onn. And could be rephrased in the following way.
[Obesity and its influencing factors in primary school students from Kaifu District of Changsha City].

OBJECTIVE To study the prevalence of obesity and the influencing factors for obesity in primary school students from Kaifu District of Changsha City. METHODS A total of 4 140 students aged 7 to 12 years sampled randomly from Kaifu District of Changsha City were enrolled. Obesity was identified based on the body mass index (BMI). The influencing factors for obesity were investigated by non-logistic regression analysis. RESULTS The prevalence of overweight and obesity were 9.76% and 7.39% respectively, and the prevalence of obesity in boys and girls were 9.37% and 5.13% respectively (P<0.05). The obese children had significantly higher BMI, waist circumference (WC), waist to hip ratio(WHR), percentage of body fat (%BF), systolic blood pressure, and serum triglyceride (TG) and low density lipoprotein-cholesterol (LDL-C) levels but significantly lower serum high density lipoprotein-cholesterol (HDL-C) level compared with the children with normal weight. BMI, %BF, WC and WHR were all positively correlated to serum levels of TG and LDL-C in obese children. Binge overeating, increased television viewing time, fast speed of eating and increased consumption of fried foods are all risk factors for the development of obesity. Preference for physical activity and sufficient physical activity were protective factors for obesity. CONCLUSIONS The prevalence of obesity of primary school students from Kaifu District of Changsha City is high in China. The development of childhood obesity is associated with poor eating behaviors, less physical activity and increased television viewing time. The control of childhood obesity may be beneficial to early prevention of some adult chronic diseases.
