Full Text Available In pediatrics, skeletal maturity, also called “bone age”, an expression of biological maturity of a child, is an important quantitative measure for the clinical diagnosis of endocrinological problems and growth disorders. Bone age is also used in monitoring children with hormone therapy. Skeletal maturity may be assessed by analysis of the ossification centers of the hand, foot, knee, elbow or pelvis but most often used is the hand. Skeletal maturity diagnosis is usually based on a visual comparison of a left-hand wrist radiograph with atlas patterns and the most common method used is the Tanner-Whitehouse method. With the help of PHP and MySQL a computer-assisted software we developed, based on Tanner-Whitehouse method, for bone age assessment of children and young people. The program is a client-server one and all data are saved into a database server. The program (1 display control radiographies, schematic drawings and specifications for every stage of hand bones until maturity stage, (2 allow user to select a maturity stage for every bone, (3 save and query personal data of patients, (4 save and query consultations and (5 make consultation reports.

Patterns in connectivity and retention of simulated Tanner crab (Chionoecetes bairdi) larvae in the eastern Bering Sea

Science.gov (United States)

Richar, Jonathan I.; Kruse, Gordon H.; Curchitser, Enrique; Hermann, Albert J.

The eastern Bering Sea (EBS) population of Tanner crab (Chionoecetes bairdi) has exhibited high variability in recruitment to the commercially exploited stock since the late 1970s. Concurrently, apparent shifts in crab distribution have also been observed. Larval advection patterns and associated local retention offer a potential mechanism for these observations. The Regional Ocean Modeling System (ROMS) was used to simulate larval Tanner crab advection patterns over 1978-2004 based on larval hatching sites inferred from the distributions of reproductive females sampled during annual National Marine Fisheries Service trawl surveys. Connectivity among EBS subregions was examined by comparing start and end float locations after 60 days of simulated drift. High levels of retention (>50% of floats) were observed in the majority of source subregions, and contributed significantly to the total number of endpoints in each region. Patterns in advection and resultant interregional connectivity were variable, with strongest sustained connectivity occurring along shelf, within individual domains. Increased settlement potential in the outer domain and southern middle domain after 1990 is consistent with an observed geographic shift in fishery productivity. Apparent reliance of Bristol Bay on local larval retention validates recent spatial fishery management to conserve this area as a subpopulation.

Sweeney, M.H.; Walrath, J.; Waxweiler, R.J.

1985-08-01

A retrospective cohort mortality study was conducted on 807 fur dyers, fur dressers (tanners), and fur service workers who were pensioned between 1952 and 1977 by the Fur, Leather and Machine Workers Union of New York City. Workplace exposures of fur workers varied with job category. Dyers were exposed to oxidative dyes used in commercial hair dyes; dressers and service workers were exposed to tanning chemicals. In a comparison with the New York City population, no significant increases in mortality were observed among the fur dyers. Among fur dressers, mortality from all malignant neoplasms and lung cancer was significantly elevated, as was mortality from cardiovascular disease among fur service workers. When examined by ethnic origin, the elevated SMR values and directly age-adjusted rate ratios suggested that foreign-born fur dressers and eastern European-born fur workers experienced the highest risks for lung and colorectal cancers, respectively. These data support previous findings of increased mortality from colorectal cancer in the foreign-born population of the United States and suggest a possible occupational etiology for the observed lung cancer excess.

Indoor tanning (IT) increases risk for melanoma and is particularly common among young adult women. IT has also been linked with some psychiatric symptoms, and frequent tanning may indicate tanning dependence (addiction) associated with endorphin release during ultraviolet radiation exposure. The objective of the current study was to investigate associations between IT, tanning dependence, and psychiatric and substance use symptoms in young adult women. Cross-sectional survey and psychiatric interview. Online, except for the Mini International Neuropsychiatric Interview (MINI), which was completed over the telephone. Participants were 306 female university students aged 18 to 25 years. MINI, Seasonal Scale Index, tanning dependence scales, reporting ever having used a tanning bed or booth with tanning lamps (single item), reporting smoking a cigarette in the last 30 days (single item). Descriptive statistics, χ(2) analysis, multivariate logistic regression. Forty-six percent of the sample reported a history of IT, and 25% were classified as tanning dependent. Multivariate logistic regression analyses showed that IT was significantly associated with symptoms of alcohol use disorders, generalized anxiety, and not having social anxiety. Tanning dependence was associated with symptoms of alcohol use disorders. Tanning is of concern not only for its association with skin cancer but for its association with psychiatric and substance use symptoms. Young women with certain psychological problems may seek relief from their symptoms by IT. These findings suggest that indoor tanners may benefit from health behavior and other psychosocial interventions.

Effects of ocean acidification on juvenile red king crab (Paralithodes camtschaticus and Tanner crab (Chionoecetes bairdi growth, condition, calcification, and survival.

Directory of Open Access Journals (Sweden)

William Christopher Long

Full Text Available Ocean acidification, a decrease in the pH in marine waters associated with rising atmospheric CO2 levels, is a serious threat to marine ecosystems. In this paper, we determine the effects of long-term exposure to near-future levels of ocean acidification on the growth, condition, calcification, and survival of juvenile red king crabs, Paralithodes camtschaticus, and Tanner crabs, Chionoecetes bairdi. Juveniles were reared in individual containers for nearly 200 days in flowing control (pH 8.0, pH 7.8, and pH 7.5 seawater at ambient temperatures (range 4.4-11.9 °C. In both species, survival decreased with pH, with 100% mortality of red king crabs occurring after 95 days in pH 7.5 water. Though the morphology of neither species was affected by acidification, both species grew slower in acidified water. At the end of the experiment, calcium concentration was measured in each crab and the dry mass and condition index of each crab were determined. Ocean acidification did not affect the calcium content of red king crab but did decrease the condition index, while it had the opposite effect on Tanner crabs, decreasing calcium content but leaving the condition index unchanged. This suggests that red king crab may be able to maintain calcification rates, but at a high energetic cost. The decrease in survival and growth of each species is likely to have a serious negative effect on their populations in the absence of evolutionary adaptation or acclimatization over the coming decades.

Development of a software to bone age assessment by Tanner and Whitehouse method

International Nuclear Information System (INIS)

Caetano, Nattan R.; Ghilardi Netto, Thomaz; Tomita, Ines

2011-01-01

The aim of the present work was to optimize the process of bone age reading. Several methods existent nowadays consist of skeletal maturity analysis, based on the bone details of the hand and wrist. The most effective method is proposed by Tanner and Whitehouse (TW), which produces results about five times more accurate than the other methods like the Grelish and Pyle (GP) one, which is widely used due the simplicity of the reading processes. However, the TW method is not often used at most hospitals because it presents high complexity degree. Thus, a computational program was developed to implement it in pediatric services, where the precision in bone age measurement is important. The program is similar to TW atlas, presenting images of skeletal maturity stages of analyzed bones, followed by explanatory texts. Besides, the reading processes and the calculations are automated by the program. Therefore, the diagnosis based on bone ages is produced faster and safely, taking into account that 19% of readings by means of GP present deviations of about 30% in comparison to TW. The TW method produces results with a precision five times greater than GP and with the program developed in this work, bone age reading becomes simple. The automation of bone age reading turns TW method more dynamic, enabling its use without interference in measurement values. (author)

[Age of onset of puberty in Chilean boys according to testicular volume and Tanner stage].

A secular trend towards a younger age of puberty onset has been reported in Chilean girls. To evaluate the age of onset of puberty and prevalence of early puberty in Chilean boys. A pediatric endocrinologist examined 319 children attending schools in central Santiago. Pubertal development was assessed by testicular volume (TV) and genital inspection (GI) using Tanner graduation. Precocious and early puberty development was diagnosed if TV ≥ 4 ml or GI > stage 2 occurred in boys younger than 9 years and at 9-10 years of age, respectively. Pubertal onset occurred at 10.2 ± 1.5 years according to TV and at 11.1 ± 1.6 years according to GI (p puberty was observed in 23.8% of children according to TV and 9.5% according to GI. However, no child of less than 11 years old had a TV ≥ 4 ml, genital changes and pubic hair simultaneously. Late pubertal stages occurred at the same age according to both criteria used. Body mass index z score was not associated with the age of pubertal onset. Testicular enlargement occurs one year earlier than changes in genitalia according to inspection. Testicular growth, but not late stages of puberty, are occurring one year earlier than previously reported in Chile 10 years ago.

Electroosmotic flow of Phan-Thien-Tanner fluids at high zeta potentials: An exact analytical solution

Science.gov (United States)

Sarma, Rajkumar; Deka, Nabajit; Sarma, Kuldeep; Mondal, Pranab Kumar

2018-06-01

We present a mathematical model to study the electroosmotic flow of a viscoelastic fluid in a parallel plate microchannel with a high zeta potential, taking hydrodynamic slippage at the walls into account in the underlying analysis. We use the simplified Phan-Thien-Tanner (s-PTT) constitutive relationships to describe the rheological behavior of the viscoelastic fluid, while Navier's slip law is employed to model the interfacial hydrodynamic slip. Here, we derive analytical solutions for the potential distribution, flow velocity, and volumetric flow rate based on the complete Poisson-Boltzmann equation (without considering the frequently used Debye-Hückel linear approximation). For the underlying electrokinetic transport, this investigation primarily reveals the influence of fluid rheology, wall zeta potential as modulated by the interfacial electrochemistry and interfacial slip on the velocity distribution, volumetric flow rate, and fluid stress, as well as the apparent viscosity. We show that combined with the viscoelasticity of the fluid, a higher wall zeta potential and slip coefficient lead to a phenomenal enhancement in the volumetric flow rate. We believe that this analysis, besides providing a deep theoretical insight to interpret the transport process, will also serve as a fundamental design tool for microfluidic devices/systems under electrokinetic influence.

Skin grafting is the current standard care in the treatment of full thickness burns. It was first described around 1500 BC but the vast majority of advancements have been achieved over the past 200 years. An extensive literature review was conducted on Pubmed, Medline and Google Scholar researching the evolution of skin grafting techniques. The authors concentrated on the major landmarks of skin grafting and also provide an overview of ongoing research efforts in this field. The major innovations of skin grafting include Reverdin pinch grafting, Ollier grafting, Thiersch grafting, Wolfe grafting, Padgett dermatome and modifications, Meek-wall microdermatome and Tanner mesh grafting. A brief description of the usage, advantages and limitations of each technique is included in the manuscript. Skin grafting technique have evolved significantly over past 200 years from Reverdin pinch grafting to modern day meshed skin grafts using powered dermatome. Increasing the expansion ratio and improving the cosmetic and functional outcome are the main focus of ongoing skin grafting research and emerging techniques (such as Integra ® , Recell ® , Xpansion ® ) are showing promise.

Metabolic syndrome (MetS) is a major risk factor for cardiovascular disease and diabetes. Previous studies in obese children demonstrating a positive association between serum uric acid (sUA) and components of MetS are confounded by lack of uniformity in age and pubertal status of children. Therefore, we have examined the role of sUA in MetS and its components in pre-pubertal children (Tanner Stage I, age ≤ 9 years). Pre-pubertal obese children (32 boys, 27 girls, age 6-9 years) were recruited from Nuevo Leon, Mexico. For comparison, an equal number of children with normal body mass index (BMI) in the same age range (22 Boys, 39 girls, age 6-9 years) were also recruited from the same community. Presence of MetS and its components was defined according to the criteria of International Diabetes Federation. Fasting blood was analyzed for lipids, glucose, insulin, and uric acid. Among the obese children, sUA was positively associated with insulin resistance and hypertriglyceridemia and negatively associated with high density lipoprotein-cholesterol (HDLc). Subjects were three times more likely to have a MetS diagnosis per one unit (md/dL) difference in sUA. Of the 59 obese pre-pubertal children, 20 were classified as having MetS defined by the presence of abdominal obesity and two or more of other components described under methods. Of these, 57.1% (20/61) had sUA between 5.1 and 7.1 mg/dl. The findings of this study clearly indicate a positive relationship between uric acid and MetS and its components in pre-pubertal obese children with Tanner stage I and ≤9 years of age.

Secular trends in height and weight are reasonably well documented in Europe. Corresponding observations for skeletal maturation are lacking. To assess secular trends in height, body mass and skeletal maturity of Portuguese children and adolescents and to provide updated reference values for skeletal maturity scores (SMSs). Data for 2856 children and adolescents of 4-17 years, 1412 boys and 1444 girls, from The 'Madeira Growth Study' (MGS; 1996-1998) and from the'Healthy Growth of Madeira Children Study' (CRES; 2006) were used. Height and body mass were measured. Skeletal maturity was assessed with the Tanner-Whitehouse 2 and 3 methods. Children from CRES were taller and heavier than peers from MGS. Differences in height reached 5.8 cm in boys and 5.5 cm in girls. RUS SMSs did not differ consistently between surveys boys, while higher RUS scores were observed in CRES girls. Adult RUS SMSs for MGS and CRES combined were attained at 15.8 years in boys and 14.8 years in girls. Corresponding ages for adult Carpal SMSs were 14.4 and 14.0, respectively. The short-term trends for height and mass were not entirely consistent with the trends in RUS and Carpal SMSs and SAs.

Modern optical fibers require double-layer coating on the glass fiber to provide protection from signal attenuation and mechanical damage. The most important plastic resins used in wires and optical fibers are plastic polyvinyl chloride (PVC) and low-high density polyethylene (LDPE/HDPE), nylon and Polysulfone. In this paper, double-layer optical fiber coating is performed using melt polymer satisfying PTT fluid model in a pressure type die using wet-on-wet coating process. The assumption of fully developed flow of Phan-Thien-Tanner (PTT) fluid model, two-layer liquid flows of an immiscible fluid is modeled in an annular die, where the fiber is dragged at a higher speed. The equations characterizing the flow and heat transfer phenomena are solved exactly and the effects of emerging parameters (Deborah and slip parameters, characteristic velocity, radii ratio and Brinkman numbers on the axial velocity, flow rate, thickness of coated fiber optics, and temperature distribution) are reported in graphs. It is shown that an increase in the non-Newtonian parameters increase the velocity in the absence or presence of slip parameters which coincides with related work. The comparison is done with experimental work by taking λ → 0 (non-Newtonian parameter).

Full Text Available The article presents preliminary data from a prospective investigation in a sample of healthy 14-17-year-old students from a technical school in Sao Paulo, Brazil. Ninety-six Tanner stage 5 and thirty-one Tanner stage 4 adolescents were evaluated: testicular volume was measured using a Prader orchidometer, and semen analysis was performed according to standard procedures. Median testicular volume was 20.0ml among Tanner 5 students and 15.0ml in Tanner 4 students in both the right and left testes. No significant differences were found in sperm volume or motility. Median concentration was 66.0 million/ml for Tanner 5 and 47.0 million/ml for Tanner 4 subjects. Morphological patterns showed abnormal forms in 81.9% of Tanner 5 and 93.6% of Tanner 4 adolescents.

Hemodynamic factors, such as Wall Shear Stress (WSS), play a substantial role in arterial diseases. In the larger arteries, such as the carotid artery, interaction between the vessel wall and blood flow affects the distribution of hemodynamic factors. The fluid is considered to be non-Newtonian, whose flow is governed by the equation of a second-grade viscoelastic fluid and the effects of viscoelastic on blood flow in carotid artery is investigated. Pulsatile flow studies were carried out in a 3D model of carotid artery. The governing equations were solved using finite volume C++ based on open source code, OpenFOAM. To describe blood flow, conservation of mass and momentum, a constitutive relation of simplified Phan-Thien-Tanner (sPTT), and appropriate relations were used to explain shear thinning behavior. The first recirculation was observed at t = 0.2 s, in deceleration phase. In the acceleration phase from t = 0.3 s to t = 0.5 s, vortex and recirculation sizes in bulb regions in both ECA and ICA gradually increased. As is observed in the line graphs based on extracted data from ICA, at t = 0.2 s, τyy is the maximum amount of wall shear stress and τxy the minimum one. The maximum shear stress occurred in the inner side of the main branch (inner side of ICA and ECA) because the velocity of blood flow in the inner side of the bulb region was maximum due to the created recirculation zone in the opposite side in this area. The rheology of blood flow and shear stress in various important parts (the area that are in higher rates of WSS such as bifurcation region and the regions after bulb areas in both branches, Line1-4 in Fig. 7) were also analyzed. The investigation of velocity stream line, velocity profile and shear stress in various sections of carotid artery showed that the maximum shear stress occurred in acceleration phase and in the bifurcation region between ECA and ICA which is due to velocity gradients and changes in thinning behavior of blood and

To compare the reliability of the Greulich-Pyle (GP) method, Tanner-Whitehouse 3 (TW3) method and Korean standard bone age chart (KS) in the evaluation of bone age of prepubertal healthy Korean children. Left hand-wrist radiographs of 212 prepubertal healthy Korean children aged 7 to 12 years, obtained for the evaluation of the traumatic injury in emergency department, were analyzed by two observers. Bone age was estimated using the GP method, TW3 method and KS, and was calculated in months. The correlation between bone age measured by each method and chronological age of each child was analyzed using Pearson correlation coefficient, scatterplot. The three methods were compared using one-way analysis of variance. Significant correlations were found between chronological age and bone age estimated by all three methods in whole group and in each gender (R2 ranged from 0.87 to 0.9, p < 0.01). Although bone age estimated by KS was slightly closer to chronological age than those estimated by the GP and TW3 methods, the difference between three methods was not statistically significant (p > 0.01). The KS, GP, and TW3 methods show good reliability in the evaluation of bone age of prepubertal healthy Korean children without significant difference between them. Any are useful for evaluation of bone age in prepubertal healthy Korean children.

Effect of slip on heat transfer and entropy generation characteristics of simplified Phan-Thien–Tanner fluids with viscous dissipation under uniform heat flux boundary conditions: Exponential formulation

International Nuclear Information System (INIS)

Anand, Vishal

2016-01-01

Highlights: • Exponential formulation of s-PTT model used. • Heat transfer and entropy generation characteristics studied. • Effects of three slip laws examined. • Exponential formulation more accurate than linear formulation. - Abstract: This study concerns the heat transfer and entropy generation characteristics of viscoelastic fluid flow modeled by the exponential formulation of simplified Phan-Thien–Tanner (s-PTT) model. This is the first such study in literature of thermal behavior of viscoelastic fluids modeled by the exponential formulation of s-PTT model. The flow between two parallel plates is laminar, hydrodynamically and thermally fully developed, viscous dissipative and subject to uniform heat flux on the walls. The slip velocity boundary condition is imposed on the fluid–solid interface and the slip is captured by three slip laws, namely, Navier's non-linear slip law, Hatzikiriakos slip law, and asymptotic slip law. The governing equations have been solved analytically. Closed form solutions for the velocity distribution have been derived while the temperature distribution is presented in terms of an infinite but convergent series. The results pertaining to the three slip laws have been presented in detail. Finally, a comparison has been made between the results for exponential formulation and those for the linear formulation of the s-PTT model. The comparison shows that results for linear formulation deviate significantly from those for exponential formulation and thus the accuracy of the exponential formulation justifies the extra mathematical complexity which it entails.

The success of oil well drilling process depends on the correct prediction of the velocities and stresses fields inside the gap between the drill string and the rock formation. Using CFD is possible to predict the behavior of the drilling fluid flow along the annular space, from the bottom to the top of the well. Commonly the drilling fluid is modeled as a Herschel-Bulkley fluid. An alternative is to employ a non-linear viscoelastic model, like the one developed by Phan-Thien-Tanner (PTT). In the present work the PTT constitutive equation is used to model the drilling fluid flow along the annular space. Thus, this work investigates the influence of the Deborah number on the laminar flow pattern through the numerical solution of the equations formed by the coupled velocity-pressure-stress fields. The results are analyzed and validated against the analytical solution for the fully developed annular pipe flow. The relation between the Deborah number (De) and the entry length is investigated, along with the influence of high values of Deborah number on the friction factor, stress and velocity fields.

Fasting glucose (hexoquinase) and insulin blood levels (chemiluminiscence), were determined and HOMA index was calculated. Percentile distributions of these variables were calculated. The reference group included only subjects with normal body mass index and fasting blood glucose (n = 1,192). Girls had higher insulin and HOMA values than boys (12.5 ± 6.0 and 9.1 ± 4.9 μϋ/mL (p HOMA mean values than subjects with Tanner III and IV (9.0 ± 4.3 and 12.5 ± 6.2μϋ/ml (p HOMA distributions according to sex and maturation, was selected as the upper cut-off point to identify individuals with insulin resistance. HOMA cutoff point for Tanner I and II boys was 3.2, for Tanner I and II girls was 4.1, for Tanner III and IV boys was 4.2 and for Tanner III and IV girls was 5.0.

Estimations of bone maturation and calculations of prediction of adult height as tools for the evaluation of growth disorders

Energy Technology Data Exchange (ETDEWEB)

Zachmann, M

1982-03-01

The methods of estimation of bone maturation (Greulich and Pyle, Tanner et al.) and the possibilities for the calculation of future adult heigth (Bayley and Pinneau, Roche et al., Tanner et al.) are briefly described and their advantages and disadvantages in normal children and in children with growth disorders are discussed. In normal children, all methods provide valuable results, but there are small differences of precision depending on whether the pubertal development is early, average, or late. In pathological conditions, however, as e.g. in precocious puberty or in girls with Turner syndrome, the methods of Roche et al. and of Tanner et al. may overestimate adult height considerably, while that of Bayley and Pinneau remains reasonably accurate. A computerized system, which facilitates the complicated and time-consuming calculations is briefly presented.

Our aim is to describe changes in the muscle-bone unit assessed as a ratio of bone mineral content (BMC) to lean body mass (LBM) through puberty at total body and various skeletal sites in Indian boys and girls. A cross-sectional study was conducted (888 children, 480 boys, aged 5-17 years) in Pune, India. Pubertal staging was assessed. BMC, LBM and fat percentage at the arms, legs, android, gynoid and total body (less the head) were assessed by dual energy X-ray absorptiometry. The amount of BMC per unit LBM (BMC/LBM) was computed. Changes in mean BMC/LBM at 5 Tanner (pubertal) stages after adjustment for age and fat percentage were calculated. In boys, adjusted BMC/LBM was significantly higher with successive Tanner stages [legs (TS-II vs TS-I), android (TS-III vs TS-II, TS-IV vs TS-III) and gynoid region (TS-III vs TS-II and TS-II vs TS-I) (p LBM was significantly higher with successive Tanner stages at total body, legs and gynoid (TS-III vs TS-II; TS-II vs TS-I; TS-V vs TS-IV), arms (TS-I to TS-V) and android regions (TS-V vs TS-IV) (p LBM than girls at earlier Tanner stages (TS-I to TS-III), whereas girls had significantly higher adjusted BMC/LBM than boys at later Tanner stages (TS-IV, TS-V) (p LBM with successive pubertal stages. Girls had higher BMC/LBM than boys which may possibly act as a reservoir for later demands of pregnancy and lactation.

To determine how the homeostasis model assessment of insulin resistance (HOMA-IR) is related to metabolic risk in a sample of overweight and obese Chilean youths accounting for Tanner stage. A cross-sectional study assessing 486 overweight and obese youths (aged 5-15 years) recruited from the University of Chile, Pediatric Obesity Clinic. We measured anthropometry, Tanner stage, HOMA-IR, and laboratory tests related to metabolic risk. HOMA-IR was categorized by quartile for children (Tanner stages I and II) and adolescents (Tanner stage III and above) from a normative Chilean sample. Children and adolescents with HOMA-IR in the highest quartile were likely to have higher body mass index (BMI) Z-scores, elevated waist circumference, systolic and diastolic blood pressure, and triglycerides and low high-density lipoprotein. HOMA-IR had good negative predictive value for characteristics of the metabolic syndrome (MetS; 0.82). In a multivariate regression model, BMI Z-score [odds ratio (OR) 1.5] and HOMA-IR (OR 3.3) predicted 22% of the variance for the MetS, with 36% of the explained variance attributed to HOMA-IR. In a large clinical sample of overweight and obese Chilean youths, HOMA-IR ≥ 75th percentile was significantly associated with the cluster of factors referred to as the MetS. We emphasize the importance of establishing percentiles for HOMA-IR based on a normative sample and taking Tanner stage into account. Although BMI is easy to assess and interpret with minimal costs in a clinical setting, adding HOMA-IR explains more of the variance in the MetS than BMI Z-score alone. © 2011 John Wiley & Sons A/S.

2012-02-01

Full Text Available Abstract Background Despite educational and public health campaigns to convey the risks of indoor tanning, many individuals around the world continue to engage in this behavior. Few descriptive studies of indoor tanning have collected information pertaining to the lifetime history of indoor tanning, thereby limiting our ability to understand indoor tanning patterns and potentially target interventions for individuals who not only initiate, but continue to persistently engage in indoor tanning. Methods In-person interviews elicited detailed retrospective information on lifetime history of indoor tanning among white individuals (n = 401 under age 40 seen by a dermatologist for a minor benign skin condition. These individuals were controls in a case-control study of early-onset basal cell carcinoma. Outcomes of interest included ever indoor tanning in both males and females, as well as persistent indoor tanning in females - defined as females over age 31 who tanned indoors at least once in the last three or all four of four specified age periods (ages 11-15, 16-20, 21-30 and 31 or older. Multivariate logistic regression was used to identify sociodemographic and lifestyle correlates of ever and persistent indoor tanning in females. Results Approximately three-quarters (73.3% of females and 38.3% of males ever tanned indoors, with a median age of initiation of 17.0 and 21.5, respectively. Among indoor tanners, 39.3% of females and 21.7% of males reported being burned while indoor tanning. Female ever indoor tanners were younger, had darker color eyes, and sunbathed more frequently than females who never tanned indoors. Using unique lifetime exposure data, 24.7% of female indoor tanners 31 and older persistently tanned indoors starting as teenagers. Female persistent indoor tanners drank significantly more alcohol, were less educated, had skin that tanned with prolonged sun exposure, and sunbathed outdoors more frequently than non-persistent tanners

Childhood and adolescence are critical periods of bone mineral content (BMC) accrual that may have long-term consequences for osteoporosis in adulthood. Adequate dietary calcium intake and weight-bearing physical activity are important for maximizing BMC accrual. However, the relative effects of physical activity and dietary calcium on BMC accrual throughout the continuum of pubertal development in childhood remains unclear. The purpose of this study was to determine the effects of self-reported dietary calcium intake and weight-bearing physical activity on bone mass accrual across the five stages of pubertal development in a large, diverse cohort of US children and adolescents. The Bone Mineral Density in Childhood study was a mixed longitudinal study with 7393 observations on 1743 subjects. Annually, we measured BMC by dual-energy X-ray absorptiometry (DXA), physical activity and calcium intake by questionnaire, and pubertal development (Tanner stage) by examination for up to 7 years. Mixed-effects regression models were used to assess physical activity and calcium intake effects on BMC accrual at each Tanner stage. We found that self-reported weight-bearing physical activity contributed to significantly greater BMC accrual in both sexes and racial subgroups (black and nonblack). In nonblack males, the magnitude of the activity effect on total body BMC accrual varied among Tanner stages after adjustment for calcium intake; the greatest difference between high- and low-activity boys was in Tanner stage 3. Calcium intake had a significant effect on bone accrual only in nonblack girls. This effect was not significantly different among Tanner stages. Our findings do not support differential effects of physical activity or calcium intake on bone mass accrual according to maturational stage. The study demonstrated significant longitudinal effects of weight-bearing physical activity on bone mass accrual through all stages of pubertal development. © 2014 American

Review of interventions to reduce ultraviolet tanning: Need for treatments targeting excessive tanning, an emerging addictive behavior.

Science.gov (United States)

Stapleton, Jerod L; Hillhouse, Joel; Levonyan-Radloff, Kristine; Manne, Sharon L

2017-12-01

Millions of Americans engage in tanning each year, defined as intentional ultraviolet radiation (UVR) exposure in the form of sunbathing or the use of indoor tanning beds. An emerging body of research suggests that UVR has addictive properties and some tanners engage in excessive tanning. This article provides an overview of the evidence of tanning addiction and a systematic review of existing tanning interventions with the goal of evaluating their potential to impact addicted tanners. Our search identified 24 intervention studies that were summarized and discussed according to 3 primary themes. First, there is a dearth of tanning interventions that target excessive tanning or are designed as treatments for tanning addiction. Second, tanning interventions are primarily educational interventions designed to increase knowledge of the risks of tanning. Third, there are notable aspects of existing tanning interventions that are relevant to addiction science, including the use of brief motivational and cognitive-behavioral-based interventions. Future directions are considered including recommendations for utilizing the existing evidence base to formulate interventions targeting excessive tanners.

Raw hide/skins come to the tanners as a by-product of meat industry which is converted into value-added leather as product for fashion market. Leather manufacturing is a chemical process of natural biological matrix. It employs a huge quantity of water and inorganic and organic chemicals for processing and thereby discharges solid and liquid wastes into the environment. One of the potential solid wastes generated from leather industry is chrome-tanned leather shavings (CTLSs), and its disposal is increasingly becoming a huge challenge on disposal to tanners due to presence of heavy metal chromium. Hence, finding a sustainable solution to the CTLS disposal problem is a prime challenge for global tanners and researchers. This paper aims to the deeper review of various disposal methods on CTLS such as protein, chromium, and energy recovery processes and its utilization methodologies. Sustainable technologies have been developed to overcome CTLS solid wastes emanating from leather processing operations. Further, this review paper brings a broader classification of developed methodologies for treatment of CTLSs.

Urinary hormone concentrations are often adjusted to correct for hydration status. We aimed to determine whether first morning void urine hormones in growing adolescents require adjustments and, if so, whether urinary creatinine or specific gravity are better adjustments. The study population was adolescents aged 10.1 to 14.3 years initially who provided fasting morning blood samples at 0 and 12 months (n = 343) and first morning urine every three months (n = 644). Unadjusted, creatinine and specific gravity-adjusted hormonal concentrations were compared by Deming regression and Bland-Altman analysis and grouped according to self-rated Tanner stage or chronological age. F-ratios for self-rated Tanner stages and age groups were used to compare unadjusted and adjusted hormonal changes in growing young adolescents. Correlations of paired serum and urinary hormonal concentration of unadjusted and creatinine and specific gravity-adjusted were also compared. Fasting first morning void hormone concentrations correlated well and were unbiased between unadjusted or adjusted by either creatinine or specific gravity. Urine creatinine concentration increases with Tanner stages, age and male gender whereas urine specific gravity was not influenced by Tanner stage, age or gender. Adjustment by creatinine or specific gravity of urinary luteinizing hormone, estradiol, testosterone, dihydrotestosterone and dehydroepiandrosterone concentrations did not improve correlation with paired serum concentrations. Urine steroid and luteinizing hormone concentrations in first morning void samples of adolescents are not significantly influenced by hydration status and may not require adjustments; however, if desired, both creatinine and specific gravity adjustments are equally suitable. © The Author(s) 2015.

To compare the associations between neuromuscular performance and anthropometric characteristics with habitual levels of physical activity in boys and girls during the initial stages of puberty. In a cross-sectional study of 72 healthy children (39 boys and 33 girls) ranging in age from 8 to 14 years, sex differences in anthropometric and motor performance characteristics were compared at 3 Tanner stages (T1-T3). Outcome variables included dual-energy x-ray absorptiometry measurements of body composition, assessments of neuromuscular function, and levels of physical activity (steps/day) measured by accelerometry. Physical activity was lower in girls than boys at T2 and T3, but there was no sex difference at T1. Physical activity increased with Tanner stage for boys but did not differ between Tanner stages in girls. Physical activity at each Tanner stage was strongly associated (R(2) > 0.85) with neuromuscular characteristics for both boys and girls, but percentage of body fat also was associated with physical activity for T3 girls. The attenuated gains in neuromuscular function experienced by girls in early stages of puberty were strongly associated with lower levels of physical activity, whereas the increase in physical activity exhibited by boys was mostly related to increases in the strength and endurance of leg muscles. Because sedentary activity is a known contributor to the development of obesity and type 2 diabetes in youth, this study helps to identify possible contributors to decreases in physical activity in young girls and provides potential targets for early intervention.

Ever since David Marsh and Anne Maljers ushered in the era of CLIL in 1994, this new methodology has remained a source of hot debate in ELT. While many teachers are suspicious of or indeed resistant to the very notion of Content and Language Integrated learning, others view it as the future of language teaching. For those unfamiliar with the concept, CLIL is an approach which aims to marry the learning of content to the acquisition of an additional language, thus teaching both the subject and...

2006-09-01

Motives for UV exposure have been shown to be related to appearance concerns, yet little research has examined specific tan appearance attitudes. Given this lacuna, Study 1 involved the identification of six factors among college female tanners: general attractiveness, media influence, family/friends influence, physical fitness appearance, acne reasons, and skin aging concerns. In Study 2, a separate sample of college female tanners were used to validate a higher order factor model, which demonstrated acceptable fit. Additionally, the factors converged in the expected directions, with the general attractiveness and skin aging concerns being the best correlate of UV exposure and sun-protection intentions. The relevance of these findings to skin cancer prevention is discussed.

Reflective journaling for clinical judgment development and evaluation.

Lasater, Kathie; Nielsen, Ann

2009-01-01

Reflective journaling is a strategy used often in clinical education to gain insight into students' clinical thinking; however, studies indicate that students may benefit from guided reflections. Numerous tools have been used to structure student reflection with varying results. This article describes the outcomes from using the Guide for Reflection based on Tanner's Clinical Judgment Model. The Lasater Clinical Judgment Rubric, created from the Model, is used to evaluate development of clinical judgment and provides language to communicate about clinical thinking with students. Senior immersion course competencies, also developed with language from Tanner's Clinical Judgment Model,offer a comprehensive package that fosters students' clinical judgment development, faculty-student communication about clinical judgment, and evaluation of students' clinical thinking.

Banerjee, Smita C; Hay, Jennifer L; Greene, Kathryn

2013-09-01

To examine construct and predictive utility of an adapted cognitive rationalization scale for tanning-bed use. Current/former tanning-bedusing undergraduate students (N = 216; 87.6% females; 78.4% white) at a large northeastern university participated in a survey. A cognitive rationalization for tanning-bed use scale was adapted. Standardized self-report measures of past tanning-bed use, advantages of tanning, perceived vulnerability to photoaging, tanning-bed use dependence, and tanning-bed use intention were also administered. The cognitive rationalization scale exhibited strong construct and predictive validity. Current tanners and tanning-bed-use-dependent participants endorsed rationalizations more strongly than did former tanners and not-tanning-bed-use-dependent participants respectively. Findings indicate that cognitive rationalizations help explain discrepancy between inconsistent cognitions.

Mood changes after indoor tanning among college women: associations with psychiatric/addictive symptoms

Directory of Open Access Journals (Sweden)

Carolyn Heckman

2016-06-01

Full Text Available Indoor tanning (IT has been linked with psychiatric and addictive symptoms, and frequent tanning may indicate tanning dependence (addiction. The current study evaluated the effects of an IT episode on mood states and the association of these effects with psychiatric and addictive symptoms among young adult female indoor tanners. One-hundred thirty-nine female university students aged 18-25 years who had indoor tanned completed an online survey including the Positive and Negative Affects Scales and a standardized psychiatric interview (the MINI International Neuropsychiatric Interview via telephone. Psychiatric and addictive symptoms were relatively common among these young adult female indoor tanners. Overall, participants reported significant decreases in both negative (upset, scared, irritable, nervous, jittery, afraid and positive (feeling interested mood states after their most recent tanning episode. Multivariable linear regression analyses showed that more frequent indoor tanning in the past month and symptoms of illicit drug use disorders were associated with decreases in negative mood, and symptoms of generalized anxiety disorder were associated with a decrease in feeling interested. In summary, indoor tanners report relatively high rates of psychiatric and substance use symptoms, including symptoms of tanning dependence, and indoor tanning appears to alter mood. Women with certain substance use and psychiatric characteristics may be more vulnerable to such mood changes after tanning indoors. Further research is needed to clarify the relationships among these variables.

A Pilot Study of the Normative Range of Overnight Urinary Free Cortisol Corrected for Creatinine in Children.

Wolthers, Ole D; Mersmann, Sabine; Dissanayake, Sanjeeva

2018-04-01

For more than a decade, urinary free cortisol corrected for creatinine (OUFCC) has been used to assess the systemic bioactivity of inhaled corticosteroids in children with asthma. Paediatric normative ranges, however, have not been established. The aim of the present study was to define a preliminary range for OUFCC in Tanner stage 1 children. A post hoc analysis was performed of 26 Tanner stage one children (aged 5-11 years) with mild asthma only requiring prn (pro re nata) treatment with short-acting β 2 -agonists, who participated in a 3-way cross-over knemometry study. The study comprised a run-in, two washout periods and three treatment periods (2 weeks each). Urine was collected at the end of each period. A normative range was derived using the 95% prediction interval for the geometric mean OUFCC, calculated from run-in and washout periods. Twenty-six children contributed 41 OUFCC values. The geometric mean OUFCC was 9.0 nmol/mmol (95% PI: 3.6, 22.7 nmol/mmol). The OUFCC preliminary normative range was 3.6 to 22.7 nmol/mmol in Tanner stage one children. A larger study in healthy children is warranted to confirm these findings and to assess potential differences in OUFCC across developmental stages and age groups, and by gender and race. 2013-004719-32, CLINICALTRIALS.

A physiological increase in androgen levels occurs during adolescence. Measuring androgen concentrations is the best method to distinguish normal evolution processes from hyperandrogenic disorders. The increase in circulating androgens during puberty is inversely associated with insulin sensitivity in normal weight girls. To assess circulating levels of ovarian androgens and anti-Müllerian hormone (AMH) at baseline and after GnRH analogue (GnRH-a) stimulation in normal pubertal girls across different Tanner stages. We also studied the association between this response and insulin sensitivity. Prospective study of healthy girls (6-12 years) from the local community (n = 63). Tanner I (n = 23) subjects were assessed cross-sectionally, and Tanner II girls (n = 40) were evaluated every 6 months until they reached Tanner V. Early morning dehydroepiandrosterone sulphate (DHEA-S), AMH, sex hormone-binding globulin (SHBG), androstenedione, glucose and insulin levels were measured. A GnRH-a test (500 μg/m(2) ; sc) and oral glucose intolerance test (OGTT) were performed. Differences throughout puberty were evaluated. Basal and/or stimulated Testosterone DHEA-S and 17-hydroxyprogesterone (17OHP) were inversely associated with insulin sensitivity (WIBSI) from the beginning of puberty, whereas androstenedione was directly associated with gonadotrophins. AMH was inversely associated with basal and stimulated gonadotrophins and directly with insulin area under the curve (AUC) only in the early stages of puberty. 17OHP and testosterone responsiveness increased significantly during puberty in all subjects, whereas testosterone levels changed less consistently. This pattern of ovarian-steroidogenic response was most evident during mid- and late puberty. Moreover, during late puberty only, basal 17OHP, testosterone and DHEA-S were positively associated with gonadotrophins. In normal nonobese girls born appropriate for gestational age, androgen synthesis was associated with

Instructional Storytelling: Application of the Clinical Judgment Model in Nursing.

Science.gov (United States)

Timbrell, Jessica

2017-05-01

Little is known about the teaching and learning implications of instructional storytelling (IST) in nursing education or its potential connection to nursing theory. The literature establishes storytelling as a powerful teaching-learning method in the educational, business, humanities, and health sectors, but little exploration exists that is specific to nursing. An example of a story demonstrating application of the domains of Tanner's clinical judgment model links storytelling with learning outcomes appropriate for the novice nursing student. Application of Tanner's clinical judgment model offers consistency of learning experience while preserving the creativity inherent in IST. Further research into student learning outcomes achievement using IST is warranted as a step toward establishing best practices with IST in nursing education. [J Nurs Educ. 2017;56(5):305-308.].

To investigate the importance of a maternal and paternal family history of Type 2 diabetes and their combined association with plasma leptin and adiponectin levels in overweight Latino children with a family history of Type 2 diabetes (T2DM). This cross-sectional study investigated the combined association of a maternal and paternal family history of T2DM with leptin and adiponectin in 175 overweight Latino children (age 11.1 +/- 1.7 years). All subjects had a family history of T2DM. Plasma adiponectin and leptin levels, body fat measured by dual-energy X-ray absorptiometry, Tanner stage, age and insulin sensitivity were assessed. After adjustment for age, gestational diabetes, insulin sensitivity and body fat, a combined maternal and paternal family history of T2DM was associated with higher leptin concentrations (P = 0.004) compared with a maternal or paternal family history alone. This association was most pronounced at Tanner stage 1 (P for interaction family history x tanner stage = 0.022). The presence of a combined maternal and paternal family history of T2DM accounted for 4% (P = 0.003) of the variation in leptin concentrations. No such combined association was observed for adiponectin levels. Maternal and paternal family history of T2DM may have an additive impact on leptin, but not on adiponectin levels independent of adiposity and insulin sensitivity in overweight Latino children. This may contribute to a further clinically relevant deterioration of metabolic health in this population.

The role of testosterone and estradiol in brain volume changes across adolescence: a longitudinal structural MRI study.

Herting, Megan M; Gautam, Prapti; Spielberg, Jeffrey M; Kan, Eric; Dahl, Ronald E; Sowell, Elizabeth R

2014-11-01

It has been postulated that pubertal hormones may drive some neuroanatomical changes during adolescence, and may do so differently in girls and boys. Here, we use growth curve modeling to directly assess how sex hormones [testosterone (T) and estradiol (E₂)] relate to changes in subcortical brain volumes utilizing a longitudinal design. 126 adolescents (63 girls), ages 10 to 14, were imaged and restudied ∼2 years later. We show, for the first time, that best-fit growth models are distinctly different when using hormones as compared to a physical proxy of pubertal maturation (Tanner Stage) or age, to predict brain development. Like Tanner Stage, T and E₂ predicted white matter and right amygdala growth across adolescence in both sexes, independent of age. Tanner Stage also explained decreases in both gray matter and caudate volumes, whereas E₂ explained only gray matter decreases and T explained only caudate volume decreases. No pubertal measures were related to hippocampus development. Although specificity was seen, sex hormones had strikingly similar relationships with white matter, gray matter, right amygdala, and bilateral caudate volumes, with larger changes in brain volume seen at early pubertal maturation (as indexed by lower hormone levels), followed by less robust, or even reversals in growth, by late puberty. These novel longitudinal findings on the relationship between hormones and brain volume change represent crucial first steps toward understanding which aspects of puberty influence neurodevelopment.

To describe the patients with gender identity disorder referred to a pediatric medical center. We identify changes in patients after creation of the multidisciplinary Gender Management Service by expanding the Disorders of Sex Development clinic to include transgender patients. Data gathered on 97 consecutive patients gender behaviors, provided letters from current mental health professional, and parental support. Main descriptive measures included gender, age, Tanner stage, history of gender identity development, and psychiatric comorbidity. Genotypic male:female ratio was 43:54 (0.8:1); there was a slight preponderance of female patients but not significant from 1:1. Age of presentation was 14.8 ± 3.4 years (mean ± SD) without sex difference (P = .11). Tanner stage at presentation was 4.1 ± 1.4 for genotypic female patients and 3.6 ± 1.5 for genotypic male patients (P = .02). Age at start of medical treatment was 15.6 ± 2.8 years. Forty-three patients (44.3%) presented with significant psychiatric history, including 20 reporting self-mutilation (20.6%) and suicide attempts (9.3%). After establishment of a multidisciplinary gender clinic, the gender identity disorder population increased fourfold. Complex clinical presentations required additional mental health support as the patient population grew. Mean age and Tanner Stage were too advanced for pubertal suppressive therapy to be an affordable option for most patients. Two-thirds of patients were started on cross-sex hormone therapy. Greater awareness of the benefit of early medical intervention is needed. Psychological and physical effects of pubertal suppression and/or cross-sex hormones in our patients require further investigation.

To investigate associations between aspects of time use and health-related quality of life (HRQoL) in youth. 239 obese and healthy-weight 10- to 13-year-old Australian children completed the Pediatric Quality of Life Inventory (PedsQL™) quantifying their health-related quality of life. Time use was evaluated over four days using the Multimedia Activity Recall for Children and Adolescents (MARCA), a validated 24 h recall tool. The average number of minutes/day spent in physical activity (divided into sport, active transport and play), screen time (divided into television, videogames and computer use), and sleep were calculated. Percent fat was measured using dual-energy X-ray absorptiometry, Tanner stage by self-report, and household income by parental report. Sex-stratified analysis was conducted using Partial Least Squares regression, with percent fat, Tanner stage, household income, and use-of-time as the independent variables, and PedsQL™ total, physical and psychosocial subscale scores as the dependent variables. For boys, the most important predictors of HRQoL were percent fat (negative), videogames (negative), sport (positive), and Tanner stage (negative). For girls, the significant predictors were percent fat (negative), television (negative), sport (positive), active transport (negative), and household income (positive). While body fat was the most significant correlate of HRQoL, sport was independently associated with better HRQoL, and television and videogames with poorer HRQoL. Thus, parents and clinicians should be mindful that not all physical activity and screen-based behaviours have equivocal relationships with children's HRQoL. Prospective research is needed to confirm causation and to inform current activity guidelines.

A socio-economic gradient exists for most reasons of morbidity and mortality including delayed puberty in lower (LSES) as compared to higher (HSES) socio-economic stratum and puberty is an important factor affecting bone status in children and adolescents. Thus, a cross-sectional study was conducted on 195 age-matched pairs of girls (8-17years) from LSES and HSES in Pune City, India to assess the hypothesis that socio-economic factors working through late puberty would have a negative association with bone status of adolescents. Height, weight and Tanner stage were assessed. Total body bone mineral content (TBBMC), total body bone area (TBBA), total body bone mineral density (TBBMD), lean body mass (LBM) and total body fat mass (TBFM) were measured using GE Lunar DPX Pro Pencil Beam DXA (Wisconsin, USA) scanner. Mean TBBMC (1172±434g), TBBA (1351±356cm(2)), TBBMD (0.846±0.104g/cm(2)), LBM (21,622±5306g) and TBFM (7746±5194g) in LSES girls were significantly lower than that of HSES girls [TBBMC (1483±525g), TBBA (1533±380cm(2)), TBBMD (0.942±0.119g/cm(2)), LBM (24,308±5829g) and TBFM (12,196±7404g)] (pbone parameters. The differences in TBBMC, TBBA, LBM and TBFM between the 2 socio-economic strata at Tanner stage I were not significant (p>0.1) whereas there were significant differences in these parameters from Tanner stages II to V (pbone health in adolescent girls from the lower socio-economic stratum.

Progestins can be used to attenuate endogenous hormonal effects in late-pubertal transgender (trans) adolescents (Tanner stage B4/5 and G4/5). Currently, no data are available on the effects of progestins on the development of bone mass or body composition in trans youth. To study prospectively the evolution of body composition and bone mass in late-pubertal trans adolescents using the proandrogenic or antiandrogenic progestins lynestrenol (L) and cyproterone acetate (CA), respectively. Forty-four trans boys (Tanner B4/5) and 21 trans girls (Tanner G4/5) were treated with L or CA for 11.6 (4 to 40) and 10.6 (5 to 31) months, respectively. Anthropometry, grip strength, body composition, and bone mass, size, and density were determined by dual-energy X-ray absorptiometry and peripheral quantitative computed tomography before the start of progestin and before addition of cross-sex hormones. Using L, lean mass [+3.2 kg (8.6%)] and grip strength [+3 kg (10.6%)] significantly increased, which coincided with a more masculine body shape in trans boys. Trans girls showed loss of lean mass [-2.2 kg (4.7%)], gain of fat mass [+1.5 kg (9.4%)], and decreased grip strength Z scores. CA limited normal bone expansion and impeded pubertal bone mass accrual, mostly at the lumbar spine [Z score: -0.765 to -1.145 (P = 0.002)]. L did not affect physiological bone development. Proandrogenic and antiandrogenic progestins induce body composition changes in line with the desired appearance within 1 year of treatment. Bone health, especially at the lumbar spine, is of concern in trans girls, as bone mass accrual is severely affected by androgen suppressive therapy.

Studies of the relationship of weight status with timing of puberty in boys have been mixed. This study examined whether overweight and obesity are associated with differences in the timing of puberty in US boys. We reanalyzed recent community-based pubertal data from the American Academy of Pediatrics' Pediatric Research in Office Settings study in which trained clinicians assessed boys 6 to 16 years for height, weight, Tanner stages, testicular volume (TV), and other pubertal variables. We classified children based on BMI as normal weight, overweight, or obese and compared median age at a given Tanner stage or greater by weight class using probit and ordinal probit models and a Bayesian approach. Half of boys (49.9%, n = 1931) were white, 25.8% (n = 1000) were African American, and 24.3% (n = 941) were Hispanic. For genital development in white and African American boys across a variety of Tanner stages, we found earlier puberty in overweight compared with normal weight boys, and later puberty in obese compared with overweight, but no significant differences for Hispanics. For TV (≥3 mL or ≥4 mL), our findings support earlier puberty for overweight compared with normal weight white boys. In a large, racially diverse, community-based sample of US boys, we found evidence of earlier puberty for overweight compared with normal or obese, and later puberty for obese boys compared with normal and overweight boys. Additional studies are needed to understand the possible relationships among race/ethnicity, gender, BMI, and the timing of pubertal development.

Full Text Available The hide tanners of Brazil Northeast region have in Anadenanthera colubrina (Vell. Brenan var. cebil (Gris. Alts. their only source of tannins. As the activity of exploration is extractiviste without the concern of recovery of explored trees and the absence of other tannin sources, exposes the specie to exhaustion and the tanners and extractivistes family to go bankruptcy. Thus, this work aimed to evaluate the tanin potential of Prosopis juliflora, Anadenanthera colubrina var. cebil, Anacardium occidentale, Mimosa tenuiflora, Mimosa arenosa and Croton sonderianus. These species, Anacardium occidentale, Mimosa arenosa and Mimosa temuiflora showed, respectively, 19.83%, 18.11% and 17.74% of tannins. The Anadenanthera colubrina showed 11.89% and was inferior them mentioned species. The Prosopis juliflora and Croton sonderianus showed 3.02% and 6.62%, respectively. The abundance of Mimosa arenosa and Mimosa tenuiflora in the Brazilian Semi-arid proposes them as potential of tannin production. However, there is need of researches to verify their technical viability for skins, as well as for other uses for tannins.

Adolescent development and eating disorder related quality of life in Indian females.

Lal, M; Abraham, S

2011-03-01

To study the relationship of adolescent development and eating disorder related quality of life in Indian females. 461 female school students (aged 12-17 yrs) were recruited from middle to high socio-economic status (SES), English speaking schools in Delhi, India. Adolescent development was measured by Tanner stage and months since menarche. Subjects completed the Quality of Life for Eating Disorders questionnaire (QOL ED), which included six subscores. Correlation and partial correlation coefficient analysis to control for Body Mass Index (BMI) were performed. After controlling for BMI, all adolescent development measures were correlated with the psychological feelings (PSY) subscore. This subscore contained items relating to confusion, social unease, sadness, difficulty coping, desiring perfection and loss of control. Tanner breast stage was correlated with the eating behaviour (EB) subscore. During adolescent development, Indian girls became more aware of their psychological feelings and emotions. Only those reporting breast development were using behaviours to control their body, weight and shape. These behaviours are not associated with the presence of disordered eating thoughts, such as preoccupation with food, eating, body weight or shape.

El objetivo fue describir síntomas crecientes por intoxicación con el diseño de una escala valorativa de daños crecientes, adicionalmente se evaluaron cambios histológicos de raíz tallo y hojas mediante microscopia de luz de alta resolución (MLAR. Las plantas fueron sometidas a estrés abiótico con los tratamientos de sales de CdCl2 en concentración de 10 ppm, y de Pb (NO32 500 ppm, respectivamente. Los resultados principales mostraron un mayor detrimento cuando las plantas fueron expuestas al metal plomo que al cadmio en las raíces, tallos y hojas. Se apreciaron deformaciones extremas en paredes celulares de las células del cortex y en la endodermis de la raíz; en las hojas los daños fueron notorios para ambos metales sobre todo en el parénquima clorofílico y en la deformación de paredes de la epidermis tanto en haz como envés; en los tallos aparecieron deformaciones de las células del parénquima de relleno cuando ocurre bioacumulación intensa de plomo. Estos resultados sugieren que la bioconcentración en los tejidos vegetales ocasiona trastornos histológicos, que pueden involucrar una red trófica y por consiguiente consecuencias en la Salud Pública.

Jun-Hu, Shao; Bao-Ming, Bai; Wei, Lin; Lin, Zhou

2010-01-01

For quantum sparse graph codes with stabilizer formalism, the unavoidable girth-four cycles in their Tanner graphs greatly degrade the iterative decoding performance with a standard belief-propagation (BP) algorithm. In this paper, we present a jointly-check iterative algorithm suitable for decoding quantum sparse graph codes efficiently. Numerical simulations show that this modified method outperforms the standard BP algorithm with an obvious performance improvement. (general)

The aim of this study was to examine the efficacy of three indices i.e. adiponectin/leptin ratio, HOMA-IR and HOMA-AD in assessing insulin resistance among obese children. One hundred and twenty-two obese children (57 girls, 65 boys): mean age 13.7±1.3 years, BMI 30.1±4.5kg/m(2), eight tanner stage I, 48 tanner stage II-III, 66 tanner stage IV-V, participated in this study. They were classified into four groups according to sex and the presence of metabolic syndrome characteristics: with metabolic syndrome (MS; 21 girls and 36 boys) and controls without metabolic syndrome (CON, 36 girls and 29 boys). The correlations between these three indices of insulin resistance and the MS criteria were analyzed using linear and multiple regressions and receiver operating characteristics (ROC) curves analysis. The majority of anthropometric and biological parameters as well as adiponectin/leptin ratio, HOMA-IR and HOMA-AD were significantly different between MS and CON in both sexes. Both HOMA-AD and HOMA-IR were significantly correlated with the majority of metabolic syndrome components than was the adiponectin/leptin ratio in MS of both sexes. In boys and girls with and without MS, multiple regression analyses highlighted that both HOMA-AD and adiponectin/leptin ratio (r=-0.99 and r=-0.54 for MS girls and boys respectively, 0.05HOMA-AD and HOMA-IR (r=0.66 and r=0.31 for MS girls and boys respectively, 0.05HOMA-IR. Additionally, the area under the ROC curves for predicting insulin resistance were 0.69 (CI 95%, 0.60-0.77), 0.68 (CI 95%, 0.59-0.76) and 0.71 (CI 95%, 0.62-0.79) for adiponectin/leptin ratio, HOMA-IR and HOMA-AD, respectively. The current study strengthens the validity of the HOMA-AD as an adequate tool for determining insulin resistance among obese children with MS. Copyright © 2012. Published by Elsevier Masson SAS.

Although tamoxifen has been shown to be fairly safe and effective for idiopathic pubertal gynecomastia, it remains unknown whether it is also beneficial for gynecomastia associated with endocrine disorders. Here, we report the effect of tamoxifen on pubertal gynecomastia in 2 siblings with partial androgen insensitivity syndrome (PAIS). Cases 1 and 2 presented with persistent pubertal gynecomastia at 13 and 16 years of age, respectively. Physical examinations revealed breast of Tanner stage 3 and normal male-type external genitalia in both cases. Clinical features such as female-type pubic hair and borderline small testis indicated mildly impaired masculinization. Molecular analysis identified a previously reported p.Arg789Ser mutation in the androgen receptor gene (AR) in the 2 cases. Two months of oral administration of tamoxifen ameliorated gynecomastia to Tanner stage 2 with no adverse events. Additional treatment with testosterone enanthate showed negligible effects on body hair and penile length. Hormone values of the 2 cases during tamoxifen treatment remained similar to those in previously reported untreated patients with PAIS. The results indicate that tamoxifen was effective in treating pubertal gynecomastia in these 2 patients with PAIS and may be considered as a therapeutic option in this situation pending further studies.

To examine the association between demographic and behavioral characteristics and sunburn among U.S. adults. We used 2010 National Health Interview Survey data (N=24,970) to conduct multivariable logistic regressions examining associations with having 1 or more sunburns in the past year and having 4 or more sunburns in the past year. Overall, 37.1% of adults experienced sunburn in the past year. The adjusted prevalence of sunburn was particularly common among adults aged 18-29years (52.0%), those who repeatedly burn or freckle after 2weeks in the sun (45.9%), whites (44.3%), indoor tanners (44.1%), those with a family history of melanoma (43.9%), and those who are US-born (39.5%). Physical activity, alcohol consumption, and overweight/obesity were positively associated with sunburn (all Psunburn (P=0.35). Among those who were sunburned in the past year, 12.1% experienced 4 or more sunburns. Sunburn is common, particularly among younger adults, those with a more sun-sensitive skin type, whites, those with a family history of melanoma, the highly physically active, and indoor tanners. Efforts are needed to facilitate sun-safety during outdoor recreation, improve the consistency of sun protection practices, and prevent sunburn, particularly among these subgroups.

Neuroimaging studies demonstrate considerable changes in white matter volume and microstructure during adolescence. Most studies have focused on age-related effects, whilst puberty-related changes are not well understood. Using diffusion tensor imaging and tract-based spatial statistics, we investigated the effects of pubertal status on white matter mean diffusivity (MD) and fractional anisotropy (FA) in 61 males aged 12.7-16.0 years. Participants were grouped into early-mid puberty (≤Tanner Stage 3 in pubic hair and gonadal development; n=22) and late-post puberty (≥Tanner Stage 4 in pubic hair or gonadal development; n=39). Salivary levels of pubertal hormones (testosterone, DHEA and oestradiol) were also measured. Pubertal stage was significantly related to MD in diverse white matter regions. No relationship was observed between pubertal status and FA. Regression modelling of MD in the significant regions demonstrated that an interaction model incorporating puberty, age and puberty×age best explained our findings. In addition, testosterone was correlated with MD in these pubertally significant regions. No relationship was observed between oestradiol or DHEA and MD. In conclusion, pubertal status was significantly related to MD, but not FA, and this relationship cannot be explained by changes in chronological age alone. Copyright © 2014 The Authors.

This study aimed to determine the effect of syntan and mimosa combination on the quality of tanned red snapper leather. The study was designed using complete randomized design (CRD) and the advanced test of Least Significant Difference (LSD) with three replications and three treatments of combined syntan and mimosa, namely: p1 (4 % syntan, 5 % mimosa), p2 (8 % syntan, 5 %mimosa), p3 (12 % syntan, 5 % mimosa). Data were analyzed using SPSS 18. The measured parameters were tensile strength (N·cm-2), elongation (%), tear strength (N·cm-1), enervation (mm), wrinkle temperature (°C), fat/oil content (%) and water content (%). The results indicate that the combined syntan and mimosa tanners gave no significant effect on the physical parameters (tensile strength, elongation, tear strength, enervation and wrinkle temperature) and chemical parameters (moisture and fat/oil). All treatments (p1, p2 and p3) met the Indonesian National Standard (SNI) 06-4586-1998 for chrome tanned freshwater snake leather for the parameters of tensile strength, tear strength, enervation, wrinkle temperature and moisture. The parameter of elongation and fat/oil content did not meet with the SNI 06-4586-1998. Among the three combinations of a tanner, syntan 4 % and mimosa 5 % treatment gave the best leather quality.

A longitudinal study: changes in cortical thickness and surface area during pubertal maturation.

Full Text Available Sex hormones have been shown to contribute to the organization and function of the brain during puberty and adolescence. Moreover, it has been suggested that distinct hormone changes in girls versus boys may contribute to the emergence of sex differences in internalizing and externalizing behavior during adolescence. In the current longitudinal study, the influence of within-subject changes in puberty (physical and hormonal on cortical thickness and surface area was examined across a 2-year span, while controlling for age. Greater increases in Tanner Stage predicted less superior frontal thinning and decreases in precuneus surface area in both sexes. Significant Tanner Stage and sex interactions were also seen, with less right superior temporal thinning in girls but not boys, as well as greater decreases in the right bank of the superior temporal sulcus surface area in boys compared to girls. In addition, within-subject changes in testosterone over the 2-year follow-up period were found to relate to decreases in middle superior frontal surface area in boys, but increases in surface area in girls. Lastly, larger increases in estradiol in girls predicted greater middle temporal lobe thinning. These results show that within-subject physical and hormonal markers of puberty relate to region and sex-specific changes in cortical development across adolescence.

Anomalous diffusion measured by a twice-refocused spin echo pulse sequence: analysis using fractional order calculus.

Gao, Qing; Srinivasan, Girish; Magin, Richard L; Zhou, Xiaohong Joe

2011-05-01

To theoretically develop and experimentally validate a formulism based on a fractional order calculus (FC) diffusion model to characterize anomalous diffusion in brain tissues measured with a twice-refocused spin-echo (TRSE) pulse sequence. The FC diffusion model is the fractional order generalization of the Bloch-Torrey equation. Using this model, an analytical expression was derived to describe the diffusion-induced signal attenuation in a TRSE pulse sequence. To experimentally validate this expression, a set of diffusion-weighted (DW) images was acquired at 3 Tesla from healthy human brains using a TRSE sequence with twelve b-values ranging from 0 to 2600 s/mm(2). For comparison, DW images were also acquired using a Stejskal-Tanner diffusion gradient in a single-shot spin-echo echo planar sequence. For both datasets, a Levenberg-Marquardt fitting algorithm was used to extract three parameters: diffusion coefficient D, fractional order derivative in space β, and a spatial parameter μ (in units of μm). Using adjusted R-squared values and standard deviations, D, β, and μ values and the goodness-of-fit in three specific regions of interest (ROIs) in white matter, gray matter, and cerebrospinal fluid, respectively, were evaluated for each of the two datasets. In addition, spatially resolved parametric maps were assessed qualitatively. The analytical expression for the TRSE sequence, derived from the FC diffusion model, accurately characterized the diffusion-induced signal loss in brain tissues at high b-values. In the selected ROIs, the goodness-of-fit and standard deviations for the TRSE dataset were comparable with the results obtained from the Stejskal-Tanner dataset, demonstrating the robustness of the FC model across multiple data acquisition strategies. Qualitatively, the D, β, and μ maps from the TRSE dataset exhibited fewer artifacts, reflecting the improved immunity to eddy currents.

2009-01-01

In this paper, we propose the approach of employing circulant permutation matrices to construct quantum quasicyclic (QC) low-density parity-check (LDPC) codes. Using the proposed approach one may construct some new quantum codes with various lengths and rates of no cycles-length 4 in their Tanner graphs. In addition, these constructed codes have the advantages of simple implementation and low-complexity encoding. Finally, the decoding approach for the proposed quantum QC LDPC is investigated.

2008-03-01

To measure the plasma levels of total homocysteine (tHcy) in children with type I diabetes mellitus and their relationship with the control of the disease. We studied a total of 46 patients with ages between 4 and 19 years. The analyzed variables were: sex, age, puberty stage by Tanner, BMI, years of evolution of the illness, self-monitoring, associated diseases, tHcy, folic acid, vitamin B12, glycosylated haemoglobin (HbA1c), lipid profile and renal function. The mean tHcy was of 5.48 +/- 1,64 microm/l, similar to that in our control population. There was a positive correlation with tHcy when analyzing the puberty stage by the Tanner scale. The years of evolution of diabetes varied between 0.4 and 15, with a mean of 5.77 +/- 3.69, with no correlation with tHcy. The glycosylated haemoglobin mean was 7.35 %, with no correlation with tHcy. The levels of folic acid and vitamin B12 were similar to the control population. The lipid profile of our patients was normal, with no association with tHcy levels. There was no correlation between GFR and tHcy. A clinically correct control of children with diabetes mellitus type 1, appears to ensure a normal total homocysteinemia, with no significant differences with the healthy individuals of the same age and social environment.

Full Text Available Background The ages of onset of pubertal characteristics are influenced by genetic, geographic, dietary and socioeconomic factors; however, due to lack of country-specific norms, clinicians in Saudi Arabia use Western estimates as standards of reference for local children. Aims The aim of the Riyadh Puberty Study was to provide data on pubertal development to determine the average age of onset of pubertal characteristics among Saudi boys. Methods Cross-sectional study among male school children in Riyadh, Saudi Arabia, in 2006, 542 schoolboys, aged 6 to 16 years old, from diverse socioeconomic levels were selected into the sample using a cluster sample design. Tanner stages were ascertained during physical examination by pediatric endocrine consultants, and also trained pediatric residents and fellows. Results The mean age (standard deviation at Tanner Stages 2, 3, 4, and 5 for pubic hair development of Saudi boys was 11.4 (1.6, 13.3 (1.3, 14.4 (1.0 and 15.1 (0.8 years old, respectively. For gonadal development, the mean age (standard deviation at stages 2, 3, 4, and 5 were 11.4 (1.5, 13.3 (1.2, 14.3 (1.1 and 15.0 (0.9 years old, respectively. Conclusion The ages of onset of pubertal characteristics, based on gonadal development, among Saudi boys are comparable to those reported in Western populations.

The purpose of this study was to examine the influence of the energy cost of swimming, body composition, and technical parameters on swimming performance in young swimmers. Twenty-nine swimmers, 15 prepubertal (11.9 +/- 0.3 years; Tanner Stages 1-2) and 14 pubertal (14.3 +/- 1.4 years; Tanner Stages 3-4) boys participated in the study. The energy cost of swimming (Cs) and stroking parameters were assessed over maximal 400-m front-crawl swimming in a 25-m swimming pool. The backward extrapolation technique was used to evaluate peak oxygen consumption (VO2peak). A stroke index (SI; m2 . s(-1) . cycles(-1)) was calculated by multiplying the swimming speed by the stroke length. VO2peak results were compared with VO2peak test in the laboratory (bicycle, 2.86 +/- 0.74 L/min, vs. in water, 2.53 +/- 0.50 L/min; R2 = .713; p = .0001). Stepwise-regression analyses revealed that SI (R2 = .898), in-water VO2peak (R2 = .358), and arm span (R2 = .454) were the best predictors of swimming performance. The backward-extrapolation method could be used to assess VO2peak in young swimmers. SI, arm span, and VO2peak appear to be the major determinants of front-crawl swimming performance in young swimmers.

Designing novel diffusion-weighted NMR and MRI pulse sequences aiming to probe tissue microstructure with techniques extending beyond the conventional Stejskal-Tanner family is currently of broad interest. One such technique, multidimensional diffusion MRI, has been recently proposed to afford...... model-free decomposition of diffusion signal kurtosis into terms originating from either ensemble variance of isotropic diffusivity or microscopic diffusion anisotropy. This ability rests on the assumption that diffusion can be described as a sum of multiple Gaussian compartments, but this is often...

We point out that a cold dark matter condensate made of gauge bosons from an extra hidden U(1) sector - dubbed hidden-photons - can create a small, oscillating electric density current. Thus, they could also be searched for in the recently proposed LC-circuit setup conceived for axion cold dark matter search by Sikivie, Sullivan and Tanner. We estimate the sensitivity of this setup for hidden-photon cold dark matter and we find it could cover a sizable, so far unexplored parameter space.

Full Text Available Leather tanning industries generally use sintetic tanner such as chrome (Cr+3 which can damage environment. Therefore, it is needed to find environmentally friendly tannery material, one is by using gambier. The aim of this research was to know tannic ability of gambier on goat’s leather and tuna fish. The gambier for tannery material contained high tannin (>70% namely Cube black and liquid waste from gambier processing. Concentration of tannery material that would be used for tanned was 1 kg. Tanned leather was tested to tannery degree (DP and physical test included pull strength, elongation, and rip strength, at same treatment compared to chrome tannery. Test results leather tanned showed that, the higher the concentration of tannery material the higher the results of DP, and the physical characteristic was better. Tanned leather from goat that used Cube black gambier concentration at 4% gave DP value approximately equal to chrome tanner (38,45% and 36,60%. For tanned tuna fish gave value of DP were 39,57% and 31,35%. Tannery material of gambier gave value of pull strength, rip strength, and elongation were higher than chrome’s. The value of pull strength of goat’s leather was 730,37 kg cm-2, tuna fish was 353,33 kg cm-2 got from liquid waste tanner. The value of rip strength fof goat’s leather was 353,33 kg cm-2, tuna fish skin 29,96 kg cm-2, and elongation value from tuna fish skin 202,0% was gotten from Cube black gambier. The result of the research showed that tannery material of gambier had tannery characteristic that can replace tanner of chrome.ABSTRAKIndustri penyamakan kulit umumnya menggunakan bahan penyamak sintetis seperti krom (Cr+3 yang dapat merusak lingkungan.

The Rayleigh–Bénard convection for non-Newtonian fluids possessing both viscoelastic and shear-thinning behaviours is examined. The Phan-Thien–Tanner (PTT) constitutive equation is implemented to model the non-Newtonian character of the fluid. It is found that while the shear-thinning and viscoelastic effects could annihilate one another for the steady roll flow, presence of both behaviours restricts the roll stability limit significantly compared to the cases when the fluid is either inelastic shear-thinning or purely viscoelastic with constant viscosity.

Weight-bearing exercise and bone mineral accrual in children and adolescents: a review of controlled trials.

Science.gov (United States)

Hind, K; Burrows, M

2007-01-01

Osteoporosis is a serious skeletal disease and as there is currently no cure, there is a large emphasis on its prevention, including the optimisation of peak bone mass. There is increasing evidence that regular weight-bearing exercise is an effective strategy for enhancing bone status during growth. This systematic review evaluates randomised and non-randomised controlled trials to date, on the effects of exercise on bone mineral accrual in children and adolescents. An online search of Medline and the Cochrane database enabled the identification of studies. Those that met the inclusion criteria were included in the review and graded according to risk for bias. Twenty-two trials were reviewed. Nine were conducted in prepubertal children (Tanner I), 8 in early pubertal (Tanner II-III) and 5 in pubertal (Tanner IV-V). Sample sizes ranged from n=10 to 65 per group. Exercise interventions included games, dance, resistance training and jumping exercises, ranging in duration from 3 to 48 months. Approximately half of the trials (n=10) included ground reaction force (GRF) data (2 to 9 times body weight). All trials in early pubertal children, 6 in pre pubertal and 2 in pubertal children, reported positive effects of exercise on bone (P<0.05). Mean increases in bone parameters over 6 months were 0.9-4.9% in prepubertal, 1.1-5.5% in early pubertal and 0.3-1.9% in pubertal exercisers compared to controls (P<0.05). Although weight-bearing exercise appears to enhance bone mineral accrual in children, particularly during early puberty; it remains unclear as to what constitutes the optimal exercise programme. Many studies to date have a high risk for bias and only a few have a low risk. Major limitations concerned selection procedures, compliance rates and control of variables. More well designed and controlled investigations are needed. Furthermore, the specific exercise intervention that will provide the optimal stimulus for peak bone mineral accretion is unclear. Future

BACKGROUND Skin cancer represents a significant health threat with over 1.3 million diagnoses, 8000 melanoma deaths, and more than $1 billion spent annually for skin cancer healthcare in the US. Despite findings from laboratory, case-control, and prospective studies that indicate a link between youthful indoor tanning (IT) and skin cancer, IT is increasing among US youth. Appearance-focused interventions represent a promising method to counteract these trends. METHODS A total of 430 female indoor tanners were randomized into intervention or no intervention control conditions. Intervention participants received an appearance-focused booklet based on decision-theoretical models of health behavior. Outcome variables included self-reports of IT behavior and intentions, as well as measures of cognitive mediating variables. RESULTS Normative increases in springtime IT rates were significantly lower (ie, over 35%) at 6-month follow-up in intervention versus control participants with similar reductions in future intentions. Mediation analyses revealed 6 cognitive variables (IT attitudes, fashion attitudes, perceived susceptibility to skin cancer and skin damage, subjective norms, and image norms) that significantly mediated change in IT behavior. CONCLUSIONS The appearance-focused intervention demonstrated strong effects on IT behavior and intentions in young indoor tanners. Appearance-focused approaches to skin cancer prevention need to present alternative behaviors as well as alter IT attitudes. Mediational results provide guides for strengthening future appearance-focused interventions directed at behaviors that increase risk of skin cancer. PMID:18937268

(i) gender; (ii) performance and; (iii) gender versus performance interactions in young swimmers' anthropometric, kinematic and energetic variables. One hundred and thirty six young swimmers (62 boys: 12.76 ± 0.72 years old at Tanner stages 1-2 by self-evaluation; and 64 girls: 11.89 ± 0.93 years old at Tanner stages 1-2 by self-evaluation) were evaluated. Performance, anthropometrics, kinematics and energetic variables were selected. There was a non-significant gender effect on performance, body mass, height, arm span, trunk transverse surface area, stroke length, speed fluctuation, swimming velocity, propulsive efficiency, stroke index and critical velocity. A significant gender effect was found for foot surface area, hand surface area and stroke frequency. A significant sports level effect was verified for all variables, except for stroke frequency, speed fluctuation and propulsive efficiency. Overall, swimmers in quartile 1 (the ones with highest sports level) had higher anthropometric dimensions, better stroke mechanics and energetics. These traits decrease consistently throughout following quartiles up to the fourth one (i.e. swimmers with the lowest sports level). There was a non-significant interaction between gender and sports level for all variables. Our main conclusions were as follows: (i) there are non-significant differences in performance, anthropometrics, kinematics and energetics between boys and girls; (ii) swimmers with best performance are taller, have higher surface areas and better stroke mechanics; (iii) there are non-significant interactions between sports level and gender for anthropometrics, kinematics and energetics.

To evaluate the robustness of an appearance-focused intervention to prevent skin cancer in individuals reporting seasonal affective disorder (SAD) symptoms and pathological tanning motives. Randomized, controlled clinical trial. College campus. Four hundred thirty adult female indoor tanners (200 in the intervention group and 230 control participants). A booklet discussing the history of tanning, current tanning norms, UV radiation's effects on skin, recommendations for indoor tanning use focusing on abstinence and harm reduction recommendations, and information on healthier, appearance-enhancing alternatives to tanning. Self-reported attitudes, intentions, and tanning behaviors; pathological tanning motives assessed by a questionnaire developed for this study; and SAD symptoms assessed by the Seasonal Pattern Assessment Questionnaire. Two of the 4 pathological tanning scales, opiatelike reactions to tanning and dissatisfaction with natural skin tone, were significant moderators demonstrating stronger treatment effects for individuals scoring higher on these scales. Treatment effects were equivalently positive (ie, no significant moderator effects) for all levels of SAD symptoms and all levels of the other 2 pathological tanning motive scales (ie, perceiving tanning as a problem and tolerance to the effects of tanning). The appearance-focused skin cancer prevention intervention is robust enough to reduce indoor tanning among tanners who exhibit SAD symptoms or pathological tanning motives. Tailored interventions may address individuals' motivations for tanning and their relation to maladaptive behavior, such as dissatisfaction with appearance or the need for relaxation because of anxiety.

To investigate the relationships between pubertal gynecomastia, prostate-specific antigen (PSA), free androgen index (FAI), sex hormone-binding globulin (SHBG) and sex steroids. A total of 61 male adolescents (10-17 years old; mean: 13.67 +/- 1.08) with gynecomastia were enrolled into the study group. A total of 65 healthy age-matched adolescents were included in the control group. Body mass index (BMI), Tanner staging, testis volume, stretched penis length (SPL) and bone age were evaluated. Serum follicle-stimulating hormone, luteinizing hormone (LH), estradiol (E2), testosterone, free testosterone, SHBG, PSA levels were determined and FAI was calculated. In the study group, free testosterone (p = 0.012) and FAI (p = 0.05) were significantly lower than the control group. In the control group, SHBG levels decreased (p 0.05). High FAI was found to decrease the risk of gynecomastia (odds ratio: 0.211, 95% confidence interval: 0.064-0.694, p = 0.01). PSA showed a positive correlation with FAI, free testosterone, Tanner staging, testosterone, E2 and LH levels. PSA is a good indicator of androgen activity during puberty. However, owing to FAI remaining as the single significant variable for pubertal gynecomastia, we suggest that it is still the best parameter to elucidate the etiopathogenesis of gynecomastia as well as other pubertal developmental abnormalities in male adolescents, and further longitudinal studies are needed to investigate the relationships between PSA and FAI in puberty.

To describe gonadal dysfunction and evaluate polycystic ovary syndrome (PCOS) and its association with metabolic syndrome (MeS) among girls in a morbidly obese adolescent population. In a cross-sectional study of 174 girls, height, weight, waist circumference, Tanner stage, reproductive hormones, carbohydrate and lipid markers, drug use, and menstrual history were obtained at baseline. Exclusion criteria were menarcheal age PCOS or MeS classification. University medical center outpatient clinic. Ninety-eight girls ages 13-19.6 years, Tanner 5, average body mass index of 46.6 kg/m(2), menarche at 11.4 years, and average menarcheal age of 5 years. None. Polycystic ovary syndrome and MeS. Ninety-eight girls were divided into four groups: PCOS by National Institutes of Health criteria (PCOSN, n = 24), irregular menses only (n = 25), elevated T (≥55 ng/dL) only (n = 6), and obese controls (n = 43). Metabolic syndrome by modified Cook criteria affected 32 girls or 33% overall: 6 of 24 PCOSN, 7 of 25 irregular menses only, 4 of 6 elevated T only, and 15 of 43 obese controls. Polycystic ovary syndrome by National Institutes of Health criteria and its individual components were not associated with MeS after adjusting for body mass index. Unlike obese adults, PCOSN and its individual components were not associated with MeS in the untreated morbidly obese adolescent population.

This paper discusses the Stejskal-Tanner diffusion spin-echo sequence modified for the in vivo diffusion spectroscopy. The apparent diffusion constant D α was measured as a function of the diffusion time. Contrary to the results in phantom samples, a strong dependency of the D α for phosphocreatine (PCr) in the rat muscle tissue on diffusion time was observed, clearly indicating restricted diffusion effects and allowing an approximation of the size of the restricted volume (8-13 μm). This size fits well with the known dimensions of a normal muscle cell

This paper considers the Holling–Tanner model for predator–prey with self and cross-diffusion. From the Turing theory, it is believed that there is no Turing pattern formation for the equal self-diffusion coefficients. However, combined with cross-diffusion, it shows that the system will exhibit spotted pattern by both mathematical analysis and numerical simulations. Furthermore, asynchrony of the predator and the prey in the space. The obtained results show that cross-diffusion plays an important role on the pattern formation of the predator–prey system.

We propose a novel scheme for error-resilient image transmission. The proposed scheme employs a product coder consisting of low-density parity check (LDPC) codes and Reed-Solomon codes in order to deal effectively with bit errors. The efficiency of the proposed scheme is based on the exploitation of determinate symbols in Tanner graph decoding of LDPC codes and a novel product code optimization technique based on error estimation. Experimental evaluation demonstrates the superiority of the proposed system in comparison to recent state-of-the-art techniques for image transmission.

Entretanto, alterações objetivas do tamanho peniano podem levar ao diagnóstico de doenças. Além disso, é motivo comum de consulta médica a busca por parâmetros de normalidade do tamanho do pênis. Contudo, a antropometria do pênis da criança e do adolescente brasileiros ainda não foi devidamente estudada. O objetivo do estudo é realizar a antropometria do pênis de crianças e adolescentes brasileiros, estabelecendo referências para aplicação clínica. MÉTODOS: Foi realizado um estudo transversal, envolvendo 2.010 pacientes com idades variando entre 0 e 18 anos. Foram obtidas cinco medidas penianas: diâmetro da haste peniana; comprimento aparente e real do pênis flácido; comprimento aparente e real (CRTmax do pênis flácido sob tração máxima. O desenvolvimento puberal foi caracterizado pelos critérios de Tanner.

HIV-infected (HIV-pos) male children/youth showed lower bone mineral density at sexual maturity than HIV-uninfected (HIV-neg) females. It is not known whether complications of HIV disease, including abnormal body fat distribution, contribute to lower bone accrual in male HIV-pos adolescents. In a cross-sectional study, we evaluated the relationship between body composition (fat and lean mass) and bone mass in HIV-pos and HIV-neg children/youth and determined if it is modified by HIV status and sex. We used generalized estimating equations to simultaneously model the effect of fat/lean mass on multiple bone outcomes, including total body bone mineral density and bone mineral content and spine bone mineral density. We evaluated effect modification by HIV and sex. The analysis cohort consisted of 143 HIV-neg and 236 HIV-pos, of whom 55% were black non-Hispanic and 53% were male. Ages ranged from 7 to children/youth were at Tanner stage 1 and 20% at Tanner 5. Fat mass was more strongly positively correlated with bone mass in HIV-neg than HIV-pos children/youth and these relationships were more evident for total body bone than spine outcomes. Within HIV strata, fat mass and bone were more correlated in female than male children/youth. The relationship between lean mass and bone varied by sex, but not by HIV status. HIV disease diminishes the positive relationship of greater fat mass on bone mass in children/youth. Disruptions in body fat distribution, which are common in HIV disease, may have an impact on bone accretion during pubertal development.

Knowledge of bone age in achondroplasia is required for the prediction of adult height, timings of limb lengthening, and epiphysiodesis procedures. The purpose of this investigation was to determine the differences in skeletal age in achondroplasia and a control population with the Tanner-Whitehouse 3 method using the RUS score and to determine the right age for the interventional procedure for limb lengthening procedure or deformity correction in these patients. Left hand radiographs of 34 patients (age range, 5-18 years) with achondroplasia were evaluated for skeletal age using the RUS scoring system, which were compared with the left hand radiographs of 41 patients (age range, 5-18 years) without achondroplasia measuring skeletal age. The difference in chronological age and RUS bone age were evaluated statistically according to gender and age group. In the achondroplasia group, chronological age were 10.5±4.3 years for males and 10.1±3.6 years for females and RUS bone age were 9.2±4.0 years for males and 8.9±3.4 years for females, which showed statistically significantly difference (males p=0.0003 and females p 10 years in the study group, while 0.1±1.1 for 10 years in the control group, which also showed >statistically significant difference ( 10 years p 10 years in achondroplasia patients compared to nonachondroplasia patients. We recommend the use of the Tanner-Whitehouse 3 method especially the radius, ulna, short bone score to measure the skeletal age and to wait for a longer time before interventional procedures in achondroplasia patients.

In Denmark, the incidence of melanoma has been increasing since the 1960s. Intermittent exposure to ultraviolet radiation and a history of sunburn and sunbed use are known risk factors. We describe the association between use of protective measures, sun-related behaviour and experience of sunburn in the Danish population three months after the start of the campaign. A population-based sample of 3,499 persons aged 15-59 years completed a questionnaire that included items on exposure to ultraviolet radiation. We examined the relations between sunburn and sun-related behaviour by logistic regression analysis. Within the previous 12 months, 35% of the study population had experienced sunburn. Sunburn became less frequent with age (odds ratio (OR) 4.44; 15-19 vs. 50-59) and skin type (OR 2.57; I vs. III). Sunburn was negatively associated with shade and clothing and positively with use of sunscreens. We found no significant difference in sunscreen use between intentional tanners who experienced sunburn and those who did not. A larger fraction of unintentional tanners with sunburn than those who were not sunburnt had used sunscreen. Sunscreen was used to prolong the time spent in the sun by 66% of sunburnt people; however, we found no association between duration of sun exposure and sunscreen use. Future campaigns to reduce the prevalence of sunburn in the Danish population must especially target young persons and intentional tanning, and they should emphasize that sunscreen cannot be used to extend the time spent in the sun and that shade and clothing provide the best protection against sunburn.

Rigorous asymptotics of traveling-wave solutions to the thin-film equation and Tanner’s law

Science.gov (United States)

Giacomelli, Lorenzo; Gnann, Manuel V.; Otto, Felix

2016-09-01

We are interested in traveling-wave solutions to the thin-film equation with zero microscopic contact angle (in the sense of complete wetting without precursor) and inhomogeneous mobility {{h}3}+{λ3-n}{{h}n} , where h, λ, and n\\in ≤ft(\\frac{3}{2},\\frac{7}{3}\\right) denote film height, slip parameter, and mobility exponent, respectively. Existence and uniqueness of these solutions have been established by Maria Chiricotto and the first of the authors in previous work under the assumption of sub-quadratic growth as h\\to ∞ . In the present work we investigate the asymptotics of solutions as h\\searrow 0 (the contact-line region) and h\\to ∞ . As h\\searrow 0 we observe, to leading order, the same asymptotics as for traveling waves or source-type self-similar solutions to the thin-film equation with homogeneous mobility h n and we additionally characterize corrections to this law. Moreover, as h\\to ∞ we identify, to leading order, the logarithmic Tanner profile, i.e. the solution to the corresponding unperturbed problem with λ =0 that determines the apparent macroscopic contact angle. Besides higher-order terms, corrections turn out to affect the asymptotic law as h\\to ∞ only by setting the length scale in the logarithmic Tanner profile. Moreover, we prove that both the correction and the length scale depend smoothly on n. Hence, in line with the common philosophy, the precise modeling of liquid-solid interactions (within our model, the mobility exponent) does not affect the qualitative macroscopic properties of the film.

Structured LDPC Codes over Integer Residue Rings

2008-01-01

Full Text Available Abstract This paper presents a new class of low-density parity-check (LDPC codes over represented by regular, structured Tanner graphs. These graphs are constructed using Latin squares defined over a multiplicative group of a Galois ring, rather than a finite field. Our approach yields codes for a wide range of code rates and more importantly, codes whose minimum pseudocodeword weights equal their minimum Hamming distances. Simulation studies show that these structured codes, when transmitted using matched signal sets over an additive-white-Gaussian-noise channel, can outperform their random counterparts of similar length and rate.

This study evaluated the colorimeter as an objective measure of children's ultraviolet (UV) radiation exposure. Fifty-eight children, ages 6 to 9 years, attended two summer measurement sessions, with 46 attending a subsequent winter session. Comparisons between summer sessions for the L* scale showed that only the upper arm significantly changed in the tanner direction, while b* scale values indicated significant tanning for all body sites. All exposed body sites changed significantly in the less tan direction between summer and winter measurements. Using colorimeters to objectively measure children's UV exposure has potential applications for skin cancer prevention programs.

2009-02-01

Full Text Available Abstract Background Skin cancer is the most prevalent yet most preventable cancer in the US. While protecting oneself from ultraviolet radiation (UVR can largely reduce risk, rates of unprotected sun exposure remain high. Because the desire to be tan often outweighs health concerns among sunbathers, very few interventions have been successful at reducing sunbathing behavior. Sunless tanning (self-tanners and spray tans, a method of achieving the suntanned look without UVR exposure, might be an effective supplement to prevention interventions. Methods and Design This cluster randomized trial will examine whether a beach-based intervention that promotes sunless tanning as a substitute for sunbathing and includes sun damage imaging and sun safety recommendations is superior to a questionnaire only control group in reducing sunbathing frequency. Female beach visitors (N = 250 will be recruited from 2 public beaches in eastern Massachusetts. Beach site will be the unit of randomization. Follow-up assessment will occur at the end of the summer (1-month following intervention and 1 year later. The primary outcome is average sunbathing time per week. The study was designed to provide 90% power for detecting a difference of .70 hours between conditions (standard deviation of 2.0 at 1-year with an intra-cluster correlation coefficient of 0.01 and assuming a 25% rate of loss to follow-up. Secondary outcomes include frequency of sunburns, use of sunless tanning products, and sun protection behavior. Discussion Interventions might be improved by promoting behavioral substitutes for sun exposure, such as sunless tanners, that create a tanned look without exposure to UVR.

2003-01-01

Full Text Available Data obtained during the past five years have indicated that there are important age- and gender-based differences in the regulation and action of leptin in humans. To study the physiological changes of leptin during puberty in both sexes, and its relationship with body composition and sexual maturation, we measured leptin concentrations in 175 healthy adolescents (80 girls, 95 boys, 10-18 years of age, representing all pubertal stages. We excluded individuals with a body mass index (BMI below the 5thor above the 95th percentile relative to age. Serum concentrations of leptin were determined by a monoclonal antibody-based immunofluorimetric assay, developed in our laboratory. Body composition was determined by dual-energy X-ray absorptiometry. Pubertal stage was assigned by physical examination, according to Tanner criteria for breast development in females and genital development in males. Leptin concentration in girls (N = 80 presented a positive linear correlation with age (r = 0.35, P = 0.0012, BMI (r = 0.65, P < 0.0001 and %fat mass (r = 0.76, P < 0.0001. In boys (N = 95 there was a positive correlation with BMI (r = 0.49, P < 0.0001 and %fat mass (r = 0.85, P < 0.0001, but a significant negative linear correlation with Tanner stage (r = -0.45, P < 0.0001 and age (r = -0.40, P < 0.0001. The regression equation revealed that %fat mass and BMI are the best parameters to be used to estimate leptin levels in both sexes. Thus, the normal reference ranges for circulating leptin during adolescence should be constructed according to BMI or %fat mass to assure a correct evaluation.

A number of studies of adults have shown that pituitary deficiencies can develop in a considerable proportion of subjects during the acute phase of meningitis or years after the infection has disappeared. The results of the very few studies of the impact of pediatric meningitis on hypothalamic-pituitary function are conflicting. In order to determine the incidence of pituitary dysfunction in children with central nervous system infection, we evaluated pituitary function and anthropometric parameters in 19 children with meningitis of different etiologies (15 males; mean age ± standard deviation [SD] at pituitary evaluation, 5.9 ± 4.0 years; mean time from the acute event ± SD, 18 ± 10 months). All of the subjects had a normal stature and growth velocity for their age and gender, and none of them was obese. On the basis of Tanner's reference charts, 17 subjects (13 boys and all four girls) were pre-pubertal; two boys were in Tanner stage 2. None of the subjects had central hypothyroidism. All of the patients had normal serum of insulin growth factor (IGF)-I and prolactin. Their sex steroid and gonadotropin levels were concordant with their age and pubertal status. Early morning urine osmolality and serum electrolyte levels showed no signs of diabetes insipidus. All of the patients had normal plasma adrenocorticotropic hormone (ACTH) levels. Peak cortisol responses to the standard dose Synacthen test (SDST) were normal in all cases. The results showed that hypopituitarism following infectious meningitis appears to be infrequent in childhood and children's pituitary glands seem to be less vulnerable to damage than those of adults.

To analyze the correlation between subjective symptoms and clinical signs of dry eye among tannery workers. In this cross-sectional study, three classic clinical tests, namely the fluorescein tear film break-up time (FTBUT) test, the fluorescein staining (FS) test, and the Schirmer test (ST), were performed to assess the clinical signs of dry eye disease in 246 tanners who were found symptomatic for dry eye in a prior ocular surface disease index survey. All workers were male with a mean age of 35 ± 9 years, and the mean duration of work at tanneries was 8 ± 5 years. Among 246 symptomatic subjects, the FTBUT test, the FS test and the ST were positive in 63.8%, 30.9% and 41.9% workers, respectively. Mean FTBUT and ST scores were 10.6 ± 4.2 seconds and 10.1 ± 7.7mm, respectively. Mean FTBUT for mild, moderate and severe symptom categories differed significantly. Mean ST scores for the mild symptom group were significantly higher than that of the moderate group (p < 0.0001). The FTBUT and ST score showed a strong negative correlation with severity of symptoms (p < 0.0001). A moderate positive correlation was observed between FS positivity and increasing symptom severity (p < 0.0001). The effect of age was insignificant for FTBUT (p = 0.10), while significant for ST score (p < 0.001). The effect of duration of tannery work was significant for both FTBUT and ST scores (p < 0.0001). Clinical tests correlated well with symptom severity among tanners, and a multifactorial etiology is suggested for dry eye diseases.

Goldie Roth unchained: risk and its management in Lian Tanner’s Museum of Thieves

Directory of Open Access Journals (Sweden)

Wood, Danielle

2014-06-01

Full Text Available In her children’s action adventure novel Museum of Thieves, Lian Tanner overtly critiques adult risk-aversion and the over-protection of children. The protagonist is Goldie, an unruly child who escapes the oppressive regime of the City of Jewel where children up to the age of 12 are chained, for their own safety, to adult companions. Goldie escapes Jewel’s power structures and enters a mysterious museum housing the city’s unwanted wildness and danger. In its opening chapter Museum of Thieves establishes a subversive schema that problematises concepts of safety and order and glorifies chaos and risk, but this paper argues that as the novel progresses the author finds the schema increasingly difficult to control. It is tempting to read the museum as a “time out” zone such as CS Lewis’s Narnia, L Frank Baum’s Oz, and Maurice Sendak’s “place where the wild things are”: a space in which child characters can gain self-knowledge and skills before returning to an adult-dominated order. However, because of the degree to which Jewel and its structures are pathologised, Tanner finds she cannot bring Goldie back from “time out”. But rather than being a transgressive text, Museum of Thieves ends in a much less subversive place than it sets out to reach; the museum is revealed as a tightly controlled space and Goldie is well-protected, both within the diegesis by the museum’s special features, and beyond the diegesis by the author and the author’s cognisance of contemporary publishing industry expectations about the depiction of risk in children’s fiction.

2012-01-01

The paper investigates the viscoelastic behaviour of blood over low value of elasticity, to analyse the influence of inertia in the presence of elasticity. For viscoelastic fluids shear-thinning and strain-softening PTT (phan- Thien/tanner) constitutive model is employed to identify the influence of elasticity. The computational method adopted is based on a finite element semi-implicit time stepping Taylor-Galerkin/pressure-correction scheme. Simulations are conducted via atherosclerotic vessels along with various percentages of deposition at distinct values of Reynolds numbers. The numerical simulations are performed for recirculation flow structure and development of recirculation length to investigate the impact of atherosclerosis on partially blocked plaque deposited vessels.

Full Text Available Herein, we present a 14-year-old patient with short stature (134 cm referred from Paediatrics to our department for complementary evaluation since growth hormone (GH treatment failed to show any improvement. He was born premature and small for gestational age. Genital examination classified the patient as Tanner I–II with small penis and testicular size for his age. Biochemical analyses revealed normal GH levels with low serum insulin-like growth factor-1 (IGF-1. Molecular diagnosis confirmed several mutations in IGF1R and IGFALS, and so he was diagnosed with Laron Syndrome or GH insensibility and treated with IGF-1 substitutive therapy.

Design LDPC Codes without Cycles of Length 4 and 6

Directory of Open Access Journals (Sweden)

Kiseon Kim

2008-04-01

Full Text Available We present an approach for constructing LDPC codes without cycles of length 4 and 6. Firstly, we design 3 submatrices with different shifting functions given by the proposed schemes, then combine them into the matrix specified by the proposed approach, and, finally, expand the matrix into a desired parity-check matrix using identity matrices and cyclic shift matrices of the identity matrices. The simulation result in AWGN channel verifies that the BER of the proposed code is close to those of Mackay's random codes and Tanner's QC codes, and the good BER performance of the proposed can remain at high code rates.

2016-04-01

Full Text Available When in his Tanner lectures Stanley Cavell sets out to define Ordinary Language Philosophy or – rather – to explain how it demarcates philosophy as such, he takes up psychoanalytic literary criticism in order to articulate the terms of this task. Yet the constitution of the ordinary, in Cavell, is never quite accessed from within psychoanalysis-cum-literature alone; instead, it takes another relation, that of psychoanalysis and literature to classical Hollywood, for Cavell to address the ordinary in terms of its constitution. I propose to discuss this complex using two films by Billy Wilder as a passageway to Cavell’s analytic procedure.

2016-04-01

Do variants of the genes encoding follicle stimulating hormone (FSH) beta subunit (B) and FSH receptor (R) impact circulating reproductive hormone levels and ovarian follicle maturation in healthy peripubertal girls? FSHB and FSHR genetic variants exert, alone or their combination, distinct effects on reproductive hormone levels as well as ovarian follicle maturation in healthy peripubertal girls. FSHB and FSHR genetic variants impact reproductive hormone levels as well as associated pathologies in women. While FSHR c. 2039A>G is known to alter gonadotrophin levels in women, FSHR c.-29G>A has not yet been shown to exert effect and there are conflicting results concerning FSHB c.-211G>T. This population-based study included 633 girls recruited as part of two cohorts, the COPENHAGEN Puberty Study (2006-2014, a cross-sectional and ongoing longitudinal study) and the Copenhagen Mother-Child Cohort (1997-2002, including transabdominal ultrasound (TAUS) of the ovaries in a subset of 91 peripubertal girls). Clinical examinations, including pubertal breast stage (Tanner's classification B1-B5) were performed. Circulating levels of FSH, luteinizing hormone (LH), estradiol, anti-Mullerian hormone (AMH) and inhibin-B were assessed by immunoassays. In a subset of the girls (n = 91), ovarian volume and the number/size of antral follicles were assessed by TAUS. Genotypes were determined by competitive PCR. FSHR c.2039A>G minor alleles were positively associated with serum FSH (β = 0.08, P = 0.004), LH (β = 0.06, P = 0.012) and estradiol (β = 0.06, P = 0.017) (adjusted for Tanner stages). In a combined model, FSHR c.-29G>A and FSHR c.2039A>G alleles were positively associated with FSH levels in early-pubertal girls (B2 + B3, n = 327, r = 0.1, P = 0.02) and in young adolescents (B4 + B5, n = 149, r = 0.2, P = 0.01). Serum AMH and inhibin B levels were not significantly influenced by the single nucleotide polymorphisms (SNPs). Single SNPs were not associated with follicles

Full Text Available In thisarticle the authors examine the current understanding ofthe foundations ofthe philosophy of education. Lately when it is spoken about human development and education and concretized that it is the perfection of its mind. And if at the end of the twentieth century the subject of educational impact was human being, consisting of social and biological entities, at the beginning of the XXI century the situation has changed. Advances in neuroscience (Risto Nааtаnеn, James Olds, Donald Hebb, Elkhonon Goldberg and others allowed specifying the subject of the educational impact and identifying in a person the material organization that really makes him standing out from the world of living organisms. We are talking about the neural structures that are formed and developed in the human brain and which are not observed (and if they are observed, then in a different format and with different functional manifestations in the brain of higher animals. We are talking about consistently evolving neural networks and subconscious consciousness which perform the corresponding functions: subliminal (unconscious and conscious. If the consistent development of the structure of the human brain sees neuroscience, the development of the functions of this structure, considering psychology. Methods, ways and means of transmission of socio-cultural heritage from one generation to another explores pedagogy. Therefore, the philosophy of education that considers the impact of educational technology, global educational model should be based on the integration of research in neuroscience, psychology and pedagogy.

Over the past several decades, the age of pubertal onset in girls has shifted downward worldwide. As early pubertal onset is associated with increased risky behavior and psychological issues during adolescence and cardiometabolic disease and cancer in adulthood, this is an important public health concern. Exposure to endocrine disrupting chemicals during critical windows of in utero development may play a role in this trend. Our objective was to investigate trimester-specific phthalate and BPA exposure in relation to pubertal development among girls in the Early Life Exposure in Mexico to Environmental Toxicants (ELEMENT) birth cohort. We measured maternal urinary phthalate metabolites and BPA in samples collected during the first, second, and third trimesters of pregnancy. To assess reproductive development among their female children, we measured serum testosterone, estradiol, dehydroepiandrosterone sulfate (DHEA-S), inhibin B, and sex hormone-binding globulin (SHBG), and assessed sexual maturation, including Tanner staging for breast and pubic hair development and menarche status, at age 8-13 years (n = 120). We used linear and logistic regression to examine measures of trimester-specific in utero exposure as predictors of peripubertal hormone levels and pubertal onset, respectively. In secondary analyses, we evaluated estimated exposure at the midpoint of the first trimester and rates of change in exposure across pregnancy in relation to outcomes. Several phthalate metabolites measured throughout in utero development were associated with higher serum testosterone concentrations, while a number of metabolites measured in the third trimester were associated with higher DHEA-S. For example, an interquartile range (IQR) increase in mean monoethyl phthalate (MEP) levels across pregnancy was associated with 44% higher peripubertal testosterone (95% CI: 13-83%), while an IQR increase in di-2-ethylhexyl phthalate metabolites (ΣDEHP) specifically in the third trimester

The aim of this study was to examine the effect of 3-yr soccer practice on bone acquisition in prepubescent boys. We investigated 65 boys (aged 10-13 yr, Tanner stage I) at baseline, among which only 40 boys (Tanner stages II and III) have continued the 3-yr follow-up: 23 soccer players (F) completed 2-5 h of training plus 1 competition game per week and 17 controls (C). Bone mineral density (BMD, g/cm(2)) and bone mineral content (BMC, g) were measured by dual-energy X-ray absorptiometry at different sites. At baseline, BMD was higher in soccer players than in controls in the whole body and legs. In contrast, there was nonsignificant difference BMD in head, femoral neck, arms, and BMC in all measured sites between groups. At 3-yr follow-up, soccer players were found to have higher BMD and BMC at all sites than controls, except for head BMD and BMC and arms BMC in which the difference was nonsignificant between groups. During the 3-yr follow-up, the soccer players were found to gain significantly more in lumbar spine (31.2% ± 2.9% vs 23.9% ± 2.1%; p soccer players have less %BMD and %BMC changes in the head than controls. A nonsignificant difference was found in legs, dominant arm, head %BMD and %BMC changes, and whole-body %BMC changes between groups. In summary, we suggest that soccer has an osteogenic effect BMD and BMC in loaded sites in pubertal soccer players. The increased bone mass induced by soccer training in the stressed sites was associated to a decreased skull bone mass after 3 yr of follow-up.

Evapotranspiration is a key process of hydrological cycle and a sole term that links land surface water balance and land surface energy balance. Due to the higher information requirements of the Penman-Monteith method and the existing data uncertainty, simplified empirical methods for calculating potential and actual evapotranspiration are widely used in hydrological models. This is especially important in Brazil, where the monitoring of meteorological data is precarious. In this study were compared different methods for estimating evapotranspiration for Rio Grande do Sul, the Southernmost State of Brazil, aiming to suggest alternatives to the recommended method (Penman-Monteith-FAO 56) for estimate daily reference evapotranspiration (ETo) when meteorological data is missing or not available. The input dataset included daily and hourly-observed data from conventional and automatic weather stations respectively maintained by the National Weather Institute of Brazil (INMET) from the period of 1 January 2007 to 31 January 2010. Dataset included maximum temperature (Tmax, °C), minimum temperature (Tmin, °C), mean relative humidity (%), wind speed at 2 m height (u2, m s-1), daily solar radiation (Rs, MJ m- 2) and atmospheric pressure (kPa) that were grouped at daily time-step. Was tested the Food and Agriculture Organization of the United Nations (FAO) Penman-Monteith method (PM) at its full form, against PM assuming missing several variables not normally available in Brazil in order to calculate daily reference ETo. Missing variables were estimated as suggested in FAO56 publication or from climatological means. Furthermore, PM was also compared against the following simplified empirical methods: Hargreaves-Samani, Priestley-Taylor, Mccloud, McGuiness-Bordne, Romanenko, Radiation-Temperature, Tanner-Pelton. The statistical analysis indicates that even if just Tmin and Tmax are available, it is better to use PM estimating missing variables from syntetic data than

Insulin resistance (IR) in adolescence is associated with type 2 diabetes mellitus [T2DM]. The PREVIEW (Prevention of Diabetes Through Lifestyle Intervention and Population Studies in Europe and Around the World) study assessed the effectiveness of a high-protein, low-glycaemic-index diet and a moderate-protein, moderate-glycaemic-index diet to decrease IR in insulin-resistant children who were overweight or obese. Inclusion criteria were age 10 to 17 years, homeostatic model assessment of IR (HOMA-IR) ≥2.0 and overweight/obesity. In 126 children (mean ± SD age 13.6 ± 2.2 years, body mass index [BMI] z-score 3.04 ± 0.66, HOMA-IR 3.48 ± 2.28) anthropometrics, fat mass percentage (FM%), metabolic characteristics, physical activity, food intake and sleep were measured. Baseline characteristics did not differ between the groups. IR was higher in pubertal children with morbid obesity than in prepubertal children with morbid obesity (5.41 ± 1.86 vs 3.23 ± 1.86; P = .007) and prepubertal and pubertal children with overweight/obesity (vs 3.61 ± 1.60, P = .004, and vs 3.40 ± 1.50, P < .001, respectively). IR was associated with sex, Tanner stage, BMI z-score and FM%. Fasting glucose concentrations were negatively associated with Baecke sport score (r = -0.223, P = .025) and positively with daytime sleepiness (r = 0.280, P = .016) independent of sex, Tanner stage, BMI z-score and FM%. In conclusion, IR was most severe in pubertal children with morbid obesity. The associations between fasting glucose concentration and Baecke sport score and sleepiness suggest these might be possible targets for diabetes prevention. © 2018 John Wiley & Sons Ltd.

The purpose of this project was to examine the clinical judgment and reasoning skills of nursing students in high-fidelity simulation. Two levels of students (N = 104), novices and those who are slightly more advanced, participated in individual videotaped simulations. Afterward, interviews were conducted to explore what the student was thinking and feeling during simulation. Five themes emerged from the interviews: thinking like a nurse, assessment, looking for answers, communication, and magical or reflective thinking. There was a clear distinction in the reasoning skills of the novice students compared with students with more clinical experience. Tanner's model of clinical judgment in nursing is used to understand the findings of the study. Copyright 2014, SLACK Incorporated.

Protograph LDPC Codes for the Erasure Channel

Pollara, Fabrizio; Dolinar, Samuel J.; Divsalar, Dariush

2006-01-01

This viewgraph presentation reviews the use of protograph Low Density Parity Check (LDPC) codes for erasure channels. A protograph is a Tanner graph with a relatively small number of nodes. A "copy-and-permute" operation can be applied to the protograph to obtain larger derived graphs of various sizes. For very high code rates and short block sizes, a low asymptotic threshold criterion is not the best approach to designing LDPC codes. Simple protographs with much regularity and low maximum node degrees appear to be the best choices Quantized-rateless protograph LDPC codes can be built by careful design of the protograph such that multiple puncturing patterns will still permit message passing decoding to proceed

The aim of this study was to determine the utility of diffusion-weighted echo planar imaging (DW-EPI) for detecting acute and subacute brain ischemic foci less than 2 cm in size. Thirty patients underwent DW-EPI on a 1.5 T super-conducting unit using a SE-EPI sequence with an arbitrary pair of Stejskal-Tanner gradients applied along the imaging axes. DW-EPI demonstrated all the mast recent ischemic lesions as areas of decreased diffusion, providing greater conspicuity and larger size than conventional spin-echo imaging. DW-EPI is a promising method to detect within a subsecond early ischemia and reversible ischemic changes that are not demonstrate on routine spin-echo images. (author)

Effect of orientation dynamics on the growth of a passive vector in a family of model flows

International Nuclear Information System (INIS)

Gonzalez, M

2014-01-01

The stretching properties of a parameterized model flow used to study the fast dynamo (Tanner and Hughes 2003 Astrophys. J. 586 685–91) are analyzed by paying special attention to the dependence of the growth rate of a passive vector on its orientation with respect to strain principal axes. More specifically, the study brings out that, rather than strain intensity, it is the dynamics of orientation resulting from the alternating tilting of the strain principal axes that explains the evolution of the passive vector mean growth rate in this class of flows. On a more general level, this view of stretching may bring an alternative understanding of the growth mechanisms of vectors such as the magnetic field vector. (paper)

The postoperative growth rates achieved in eight early pubertal adolescent males with Crohn's disease undergoing surgery for obstructive complications is reported as a function of the use of 1 month's preoperative central venous alimentation. All patients had ileal strictures with ileocolitis, bone ages less than 13, Tanner stages 1 or 2, and growth velocities below the 3rd percentile for age. During a 3-year follow-up, those receiving preoperative venous alimentation demonstrated greater oral caloric intake (significant for 1 year) and greater postoperative growth velocity (significant for 2 years) in comparison to those patients who did not receive preoperative venous alimentation. There was no significant difference between the two groups of patients in postoperative weight gain, sexual development, and 3-year disease control.

Golfingia (Nephasoma) nicolasi n. sp. is described. It is a long, slender species with a filiform introvert that is 6 to 7 times the length of the trunk. The species was often the numerically dominant taxon in samples collected from the San Nicolas Basin, California, and was also callected from several other basins off southern California. Analyses of several collections from the San Nicolas Basin show that the population was spatially patchy; temporal variation was also indicated but only one year was sampled adequately. Average population densities were highest at the base of the slopes descending into the basin from the highly productive Santa Rosa-Cortes Ridge and Tanner Bank. G. nicolasi appears to feed on the large amounts of organic detritus that accumulate from this source.

Many young women experiment with using indoor tanning beds with some becoming regular users. There is a dearth of research focused on factors related to the development of regular tanning. This study was designed to gain an in-depth understanding of the experiences of a regular indoor tanning bed user for the purpose of discovering working hypotheses related to the development of this behavior. The article thesis is that initial interactions with tanning salon employees transmit insider knowledge that serves to encourage the regular use of indoor tanning beyond experimentation. We used Spradley's ethnographic interviewing technique to conduct six iterative interviews with a key informant who was an active indoor tanning bed user and former salon employee. The research was completed in the United States in 2015. The informant described her experiences as a salon employee including her interactions with salon patrons. The informant was trained as a salon employee to talk about tanning as a complex process that requires multiple salon visits to achieve desired results and to develop rapport with salon patrons to be viewed as an important source of guidance and advice. In the informant's experience, indoor tanning users who viewed tanning as a complex process and felt connected to salon employees were more receptive to purchasing larger amounts of bulk tanning sessions and committing to purchasing salon memberships. Findings provide insights into our understanding of the development of regular tanning behavior and we propose working hypotheses about this behavior to be examined in future research. There are also implications for policy makers to reduce excessive tanning behaviors including considering point-of-sale regulations that limit sales techniques of salon employees and pricing restrictions.

Duncan Tanner Essay Prize 2016: Historical Pageants, Citizenship, and the Performance of Women's History before Second-Wave Feminism.

Thomas, Zoë

2017-09-01

This article argues that the early twentieth-century craze for historical pageants provided an opportunity for women's groups to bring a nascent, accessible form of women's history into the lives of local communities across Britain. Mainstream historical pageants were organized across the country, depicting selected episodes from the past usually relating to the local area. However, more than 200 inter-war pageants staged by women's organizations, church groups, and a number of university colleges have not yet been studied. In these pageants, women imaginatively portrayed professional, religious, political, noble, and 'ordinary' women from across history. Prior to second-wave feminism, when scholars advanced the study of women within the academy, thousands of people had been invested in re-enacting women's history since the inter-war years. Emphasizing the bravery and public duties of women in the past, historical pageants provided a non-controversial format through which women's groups could effectively project their beliefs about the role they felt women should play as newly enfranchised citizens. These popular performances capture the dispersed, yet committed, dedication to encouraging women's social citizenship in the inter-war years, and a more pluralistic understanding of women's engagement with 'feminist' ideas in everyday life across Britain. © The Author [2017].

Background: Associations between abnormal body fat distribution and clinical variables are poorly understood in pediatric HIV disease. Objective: Our objective was to compare total body fat and its distribution in perinatally HIV-infected and HIV-exposed but uninfected (HEU) children and to evaluate associations with clinical variables. Design: In a cross-sectional analysis, children aged 7–16 y in the Pediatric HIV/AIDS Cohort Study underwent regionalized measurements of body fat via anthropometric methods and dual-energy X-ray absorptiometry. Multiple linear regression was used to evaluate body fat by HIV, with adjustment for age, Tanner stage, race, sex, and correlates of body fat in HIV-infected children. Percentage total body fat was compared with NHANES data. Results: Males accounted for 47% of the 369 HIV-infected and 51% of the 176 HEU children. Compared with HEU children, HIV-infected children were older, were more frequently non-Hispanic black, more frequently had Tanner stage ≥3, and had lower mean height (−0.32 compared with 0.29), weight (0.13 compared with 0.70), and BMI (0.33 compared with 0.63) z scores. On average, HIV-infected children had a 5% lower percentage total body fat (TotF), a 2.8% lower percentage extremity fat (EF), a 1.4% higher percentage trunk fat (TF), and a 10% higher trunk-to-extremity fat ratio (TEFR) than did the HEU children and a lower TotF compared with NHANES data. Stavudine use was associated with lower EF and higher TF and TEFR. Non-nucleotide reverse transcriptase inhibitor use was associated with higher TotF and EF and lower TEFR. Conclusion: Although BMI and total body fat were significantly lower in the HIV-infected children than in the HEU children, body fat distribution in the HIV-infected children followed a pattern associated with cardiovascular disease risk and possibly related to specific antiretroviral drugs.

Purpose To estimate the prevalence of sperm banking among adolescent males newly diagnosed with cancer and to identify factors associated with banking outcomes. Patients and Methods A prospective, single-group, observational study design was used to test the contribution of sociodemographic, medical, psychological/health belief, communication, and developmental factors to fertility preservation outcomes. At-risk adolescent males (N = 146; age 13.00 to 21.99 years; Tanner stage ≥ 3), their parents, and medical providers from eight leading pediatric oncology centers across the United States and Canada completed self-report questionnaires within 1 week of treatment initiation. Multivariable logistic regression was used to calculate odds ratios (ORs) and 95% CIs for specified banking outcomes (collection attempt v no attempt and successful completion of banking v no banking). Results Among adolescents (mean age, 16.49 years; standard deviation, 2.02 years), 53.4% (78 of 146) made a collection attempt, with 43.8% (64 of 146) successfully banking sperm (82.1% of attempters). The overall attempt model revealed adolescent consultation with a fertility specialist (OR, 29.96; 95% CI, 2.48 to 361.41; P = .007), parent recommendation to bank (OR, 12.30; 95% CI, 2.01 to 75.94; P = .007), and higher Tanner stage (OR, 5.42; 95% CI, 1.75 to 16.78; P = .003) were associated with an increased likelihood of a collection attempt. Adolescent history of masturbation (OR, 5.99; 95% CI, 1.25 to 28.50; P = .025), banking self-efficacy (OR, 1.23; 95% CI, 1.05 to 1.45; P = .012), and parent (OR, 4.62; 95% CI, 1.46 to 14.73; P = .010) or medical team (OR, 4.26; 95% CI, 1.45 to 12.43; P = .008) recommendation to bank were associated with increased likelihood of sperm banking completion. Conclusion Although findings suggest that banking is underutilized, modifiable adolescent, parent, and provider factors associated with banking outcomes were identified and should be targeted in future

In vivo high angular resolution diffusion-weighted imaging of mouse brain at 16.4 Tesla.

Othman I Alomair

Full Text Available Magnetic Resonance Imaging (MRI of the rodent brain at ultra-high magnetic fields (> 9.4 Tesla offers a higher signal-to-noise ratio that can be exploited to reduce image acquisition time or provide higher spatial resolution. However, significant challenges are presented due to a combination of longer T1 and shorter T2/T2* relaxation times and increased sensitivity to magnetic susceptibility resulting in severe local-field inhomogeneity artefacts from air pockets and bone/brain interfaces. The Stejskal-Tanner spin echo diffusion-weighted imaging (DWI sequence is often used in high-field rodent brain MRI due to its immunity to these artefacts. To accurately determine diffusion-tensor or fibre-orientation distribution, high angular resolution diffusion imaging (HARDI with strong diffusion weighting (b >3000 s/mm2 and at least 30 diffusion-encoding directions are required. However, this results in long image acquisition times unsuitable for live animal imaging. In this study, we describe the optimization of HARDI acquisition parameters at 16.4T using a Stejskal-Tanner sequence with echo-planar imaging (EPI readout. EPI segmentation and partial Fourier encoding acceleration were applied to reduce the echo time (TE, thereby minimizing signal decay and distortion artefacts while maintaining a reasonably short acquisition time. The final HARDI acquisition protocol was achieved with the following parameters: 4 shot EPI, b = 3000 s/mm2, 64 diffusion-encoding directions, 125×150 μm2 in-plane resolution, 0.6 mm slice thickness, and 2h acquisition time. This protocol was used to image a cohort of adult C57BL/6 male mice, whereby the quality of the acquired data was assessed and diffusion tensor imaging (DTI derived parameters were measured. High-quality images with high spatial and angular resolution, low distortion and low variability in DTI-derived parameters were obtained, indicating that EPI-DWI is feasible at 16.4T to study animal models of white

Full Text Available Knowledge of the processes shaping deep-sea benthic communities at seasonal scales in cold-seep environments is incomplete. Cold seeps within highly dynamic regions, such as submarine canyons, where variable current regimes may occur, are particularly understudied. Novel Internet Operated Vehicles (IOVs, such as tracked crawlers, provide new techniques for investigating these ecosystems over prolonged periods. In this study a benthic crawler connected to the NEPTUNE cabled infrastructure operated by Ocean Networks Canada was used to monitor community changes across 60 m2 of a cold-seep area of the Barkley Canyon, North East Pacific, at ~890 m depth within an Oxygen Minimum Zone (OMZ. Short video-transects were run at 4-h intervals during the first week of successive calendar months, over a 14 month period (February 14th 2013 to April 14th 2014. Within each recorded transect video megafauna abundances were computed and changes in environmental conditions concurrently measured. The responses of fauna to environmental conditions as a proxy of seasonality were assessed through analysis of abundances in a total of 438 video-transects (over 92 h of total footage. 7698 fauna individuals from 6 phyla (Cnidaria, Ctenophora, Arthropoda, Echinodermata, Mollusca, and Chordata were logged and patterns in abundances of the 7 most abundant taxa (i.e. rockfish Sebastidae, sablefish Anoplopoma fimbria, hagfish Eptatretus stoutii, buccinids (Buccinoidea, undefined small crabs, ctenophores Bolinopsis infundibulum, and Scyphomedusa Poralia rufescens were identified. Patterns in the reproductive behaviour of the grooved tanner crab (Chionnecetes tanneri were also indicated. Temporal variations in biodiversity and abundance in megabenthic fauna was significantly influenced by variabilities in flow velocity flow direction (up or down canyon, dissolved oxygen concentration and month of study.

Analytical solution for dynamic pressurization of viscoelastic fluids

International Nuclear Information System (INIS)

Hashemabadi, S.H.; Etemad, S.Gh.; Thibault, J.; Golkar Naranji, M.R.

2003-01-01

The flow of simplified Phan-Thien-Tanner model fluid between parallel plates is studied analytically for the case where the upper plate moves at constant velocity. Two forms of the stress coefficient, linear and exponential, are used in the constitutive equation. For the linear stress coefficient, the dimensionless pressure gradient, the velocity profile and the product of friction factor and Reynolds number are obtained for a wide range of flow rate, Deborah number and elongational parameter. The results indicate the strong effects of the viscoelastic parameter on the velocity profile, the extremum of the velocity, and the friction factor. A correlation for the maximum pressure rise in single screw extruders is proposed. For the exponential stress coefficient, only velocity profiles were obtained and compared with velocity profiles obtained with the linear stress coefficient

2007-01-01

Mechanical strain in biological tissues causes a change in the diffusion properties of water molecules. This paper proposes a method of estimating mechanical strain in biological tissues using diffusion magnetic resonance imaging (MRI). Measurements were carried out on uncompressed and compressed chicken skeletal muscles. A theoretical model of the diffusion of water molecules in muscle fibers was derived based on Tanner's equation. Diameter of the muscle fibers was estimated by fitting the model equation to the measured signals. Changes in the mean diffusivity (MD), the fractional anisotropy (FA), and diameter of the muscle fiber did not have any statistical significance. The intracellular diffusion coefficient (D int ) was changed by mechanical strain (p<.05). This method has potential applications in the quantitative evaluation of strain in biological tissues, a though it poses several technical challenges. (author)

Maximum sustainable yield and species extinction in a prey-predator system: some new results.

Science.gov (United States)

Ghosh, Bapan; Kar, T K

2013-06-01

Though the maximum sustainable yield (MSY) approach has been legally adopted for the management of world fisheries, it does not provide any guarantee against from species extinction in multispecies communities. In the present article, we describe the appropriateness of the MSY policy in a Holling-Tanner prey-predator system with different types of functional responses. It is observed that for both type I and type II functional responses, harvesting of either prey or predator species at the MSY level is a sustainable fishing policy. In the case of combined harvesting, both the species coexist at the maximum sustainable total yield (MSTY) level if the biotic potential of the prey species is greater than a threshold value. Further, increase of the biotic potential beyond the threshold value affects the persistence of the system.

2016-01-01

In many countries throughout the world, increasing numbers of gender nonconforming/transgender youth are seeking medical services to enable the development of physical characteristics consistent with their experienced gender. Such medical services include use of agents to block endogenous puberty at Tanner stage II with subsequent use of cross-sex hormones, and are based on longitudinal studies demonstrating that those individuals who were first identified as gender dysphoric in early or middle childhood and continue to meet the mental health criteria for being transgender at early puberty are likely to be transgender as adults. This review addresses terms and definitions applicable to gender nonconforming youth, studies that shed light on the biologic determinants of gender identity, current clinical practice guidelines for transgender youth, challenges to optimal care, and priorities for research.

Nurses need to quickly process information to form clinical judgments, communicate with the healthcare team, and guide optimal patient care. Electronic health records not only offer potential for enhanced care but also introduce unintended consequences through changes in workflow, clinical judgment, and communication. We investigated nurses' use of improvised (self-made) and electronic health record-generated cognitive artifacts on clinical judgment and team communication. Tanner's Clinical Judgment Model provided a framework and basis for questions in an online survey and focus group interviews. Findings indicated that (1) nurses rated self-made work lists and medication administration records highest for both clinical judgment and communication, (2) tools aided different dimensions of clinical judgment, and (3) interdisciplinary tools enhance team communication. Implications are that electronic health record tool redesign could better support nursing work.

Nurse educators are increasingly using high-fidelity simulators to improve prelicensure nursing students' ability to develop clinical judgment. Traditionally, oral debriefing sessions have immediately followed the simulation scenarios as a method for students to connect theory to practice and therefore develop clinical judgment. Recently, video recording of the simulation scenarios is being incorporated. This qualitative, interpretive description study was conducted to identify whether self-reflection on video-recorded high-fidelity simulation (HFS) scenarios helped prelicensure nursing students to develop clinical judgment. Tanner's clinical judgment model was the framework for this study. Four themes emerged from this study: Confidence, Communication, Decision Making, and Change in Clinical Practice. This study indicated that self-reflection of video-recorded HFS scenarios is beneficial for prelicensure nursing students to develop clinical judgment. [J Nurs Educ. 2016;55(9):522-527.].

MRI may be a noninvasive and alternative tool for skeletal age assessment in children, although few studies have reported on this topic. In this article, skeletal age was assessed over a wide range of ages using an open, compact MRI optimized for the imaging of a child's hand and wrist, and its validity was evaluated. MR images and their three-dimensional segmentation visualized detailed skeletal features of each bone in the hand and wrist. Skeletal age was then independently scored from the MR images by two raters, according to the Tanner-Whitehouse Japan system. The skeletal age assessed by MR rating demonstrated a strong positive correlation with chronological age. The intrarater and inter-rater reproducibilities were significantly high. These results demonstrate the validity and reliability of skeletal age assessment using MRI. Copyright © 2012 Wiley Periodicals, Inc.

Weighted-Bit-Flipping-Based Sequential Scheduling Decoding Algorithms for LDPC Codes

Directory of Open Access Journals (Sweden)

Qing Zhu

2013-01-01

Full Text Available Low-density parity-check (LDPC codes can be applied in a lot of different scenarios such as video broadcasting and satellite communications. LDPC codes are commonly decoded by an iterative algorithm called belief propagation (BP over the corresponding Tanner graph. The original BP updates all the variable-nodes simultaneously, followed by all the check-nodes simultaneously as well. We propose a sequential scheduling algorithm based on weighted bit-flipping (WBF algorithm for the sake of improving the convergence speed. Notoriously, WBF is a low-complexity and simple algorithm. We combine it with BP to obtain advantages of these two algorithms. Flipping function used in WBF is borrowed to determine the priority of scheduling. Simulation results show that it can provide a good tradeoff between FER performance and computation complexity for short-length LDPC codes.

Full Text Available A adolescência constitui etapa de risco para o desenvolvimento da anemia ferropriva, uma vez que ocorre aumento da necessidade de ferro decorrente do crescimento estatural e da maturação biológica. Estudaram-se 130 adolescentes, de ambos os sexos, para verificar os valores de hemoglobina sérica em diferentes fases de maturação sexual. Utilizou-se o método de fotometria para dosar a hemoglobina sérica e realizou-se auto-avaliação do estágio de maturação sexual com base nos critérios de Tanner. Os níveis médios de hemoglobina foram semelhantes entre sexos, bem como entre meninas que menstruavam ou não. O nível médio de hemoglobina foi de 13,3g/dL tanto para os meninos como para as meninas (p=0,64, com desvios-padrão de 1,12 e de 0,83, respectivamente. Entre os adolescentes estudados, 7,7% tinham anemia ferropriva. Recomenda-se atenção ao grupo de adolescentes, devido ao aumento da necessidade de ferro durante o estirão de crescimento, principalmente entre as meninas, aumentando a suscetibilidade à anemia.During adolescence, the risk of development of iron-deficiency anemia is higher because of the growth spurt and the sexual maturation which increase the iron requirement. One hundred and thirty adolescents (males and females were studied, in order to assess the serum hemoglobin values in different sexual maturation stages. The photometric method was used and a self-evaluation of the sexual maturation stage based on Tanner's criteria was applied. The average hemoglobin values were similar for both sexes, as well for girls who had menstruated or not. The average hemoglobin values were 13.3 (s.d. 1.12g/dL for males and 13.3 (s.d. 0.83g/dL for females (p=0.64. Among the studied adolescents, 7.7% had iron-deficiency anemia. Due to the iron requirement increase during the growth spurt, mainly in females, and the higher susceptibility to iron deficiency anemia, special attention to the adolescents is recommended.

How Mathematics Describes Life

Science.gov (United States)

Teklu, Abraham

2017-01-01

The circle of life is something we have all heard of from somewhere, but we don't usually try to calculate it. For some time we have been working on analyzing a predator-prey model to better understand how mathematics can describe life, in particular the interaction between two different species. The model we are analyzing is called the Holling-Tanner model, and it cannot be solved analytically. The Holling-Tanner model is a very common model in population dynamics because it is a simple descriptor of how predators and prey interact. The model is a system of two differential equations. The model is not specific to any particular set of species and so it can describe predator-prey species ranging from lions and zebras to white blood cells and infections. One thing all these systems have in common are critical points. A critical point is a value for both populations that keeps both populations constant. It is important because at this point the differential equations are equal to zero. For this model there are two critical points, a predator free critical point and a coexistence critical point. Most of the analysis we did is on the coexistence critical point because the predator free critical point is always unstable and frankly less interesting than the coexistence critical point. What we did is consider two regimes for the differential equations, large B and small B. B, A, and C are parameters in the differential equations that control the system where B measures how responsive the predators are to change in the population, A represents predation of the prey, and C represents the satiation point of the prey population. For the large B case we were able to approximate the system of differential equations by a single scalar equation. For the small B case we were able to predict the limit cycle. The limit cycle is a process of the predator and prey populations growing and shrinking periodically. This model has a limit cycle in the regime of small B, that we solved for

The Heidelberg Basin Drilling Project - Sedimentology and Stratigraphy of the Quaternary succession

Within the context of the Heidelberg Basin Drilling Project (Gabriel et al. 2008), a detailed sediment succession is presented here based upon deep drillings taken at Heidelberg UniNord and Mannheim Käfertal. Sediment structures, and micromorphological and pollen analyses were conducted and used to reconsider some of the climate transitions within the lower Pleistocene. A new and novel scenario is postulated regarding the preservation of Quaternary sediment packages within the Cenozoic Graben environment of the Heidelberg basin. The palynological evidence comprises the periods of warm climate of the Holsteinian (mainly Abies (fir), some Fagus (beech), Pterocarya & Azolla); the Cromerian (Pinus-Picea-QM (pine-spruce-QM)); the Bavelian (Abies, Tsuga (hemlock fir), QM & phases of increased NAP including Pinus); the Waalian (Abies, Tsuga, QM); and the Tiglian (Fagus & early Pleistocene taxa especially Sciadopytis, downward increasing Tertiary taxa). The sediment package was studied both macroscopically and microscopically. Both techniques provide evidence of fluvial, lacustrine and mass movement sedimentary processes. Some include evidence of periglacial processes (silt droplets within fine grained sands indicative of frozen ground conditions). The periglacial structures are often, not always, accompanied by pollen spectra dominated by pine and NAP. E.g. the Tiglian part of the succession shows periglacial sediment structures at its base and top but not in its middle sections. I.e. it appears not as a series of warm and cold phases but rather as a constant warm period with warm-cold-alternations at its bottom and top. All results illustrate sediment preservation in the Heidelberg basin almost throughout the Quaternary. This may be due to tectonic subsidence, but also to compaction by sediment loading of underlying fine sediments (Oligocene to Quaternary) leading to incomplete but virtually continuous sediment preservation (Tanner et al. 2009).

The prevalence of Idiopathic Hypogonadotropic Hypogonadism (IHH) is approximately 1 in 10,000 men. Objectives of this study were to evaluate the role of basal and stimulated serum prolactin in differentiating Constitutional Delayed Puberty (CDP) from IHH. This cross-sectional study was carried out at the Department of Diabetes and Endocrinology, Military Hospital, Rawalpindi. A total of 20 male patients presenting with provisional diagnosis of IHH/CDP were enrolled in the study. Patients with known diseases were excluded from the study. Baseline FSH, LH, testosterone, and prolactin were estimated and the patients were subjected to provocative prolactin stimulation by Thyrotropin releasing hormone stimulation (TRH) test and chlorpromazine challenge. At each 6 monthly follow-up visit for 4 years, the patients were evaluated for adrenarche, pubarche and other secondary sexual characters. Tanner scale was taken as standards for comparing stage of puberty at a particular age. No treatment was given to both groups for 2 years. At the end of 2 years IHH patients with failed puberty or progression of puberty and CDP who lagged behind by more than 2 years by Tanner scale or 4 years per bone age with compelling psychosocial or psychosexual reasons at school or at home were given short courses of 50 mg injection testosterone in an attempt to expedite the onset or progression of puberty. Patients from either group with failed puberty after low dose testosterone were managed with high dose testosterone therapy to induce secondary sexual characters. Twenty patients enrolled in the study were provisionally divided into 2 groups called IHH (n = 9), and CDP (n = 11) based on high basal and provocative serum prolactin levels in CDP group. Two patients from CDP group were lost in the follow-up leaving 9 patients in each group. A total of 10 (56%) patients, 3 (17%) from IHH group and 7 (39%) from CDP group achieved grade 4 puberty without any treatment. Remaining 8 (44%) patients, 6

We evaluated bone mineralization and metabolism changes related to vitamin D receptor (VDR) polymorphic genotypes in children with juvenile idiopathic arthritis. One hundred and ninety eight children (82 boys and 116 girls) were included in our study. Bone mineral density (BMD) was measured by lumbar spine DXA. Osteocalcin, CTX, parathyroid hormone, total and ionized calcium, inorganic phosphate, total alkaline phosphatase activity was utilized for assessment of bone metabolism. Molecular testing: TaqI (rs731236) and Cdx2 (rs11568820) polymorphisms of VDR were detected by RFLP. No differences in TaqI and Cdx2 haplotypes, genotypes and alleles distribution related with normal and low BMD (Zscore 90th percentile) had the highest frequency of allele A-contained genotypes (GA+AA) of Cdx2 VDR (p = 0.009). Girls with TT TaqI VDR, who never been treated by glucocorticoides had lower BMD-Zscore than C allele carriers (TT = -0.94SD [IQR: -2.1;-0.5], TC+CC = -0.62SD [IQR: -1.26;0.39], p = 0.03). Girls with Tanner I with TT had higher total and ionized Ca level than carriers of C allele (Ca: TT = 2.43 ± 0.15 mmol/l, TC+CC = 2.28 ± 0.2 mmol/l, p = 0.024; Ca(2+): TT = 1.15 ± 0.08 mmol/l, TC+CC = 1.06 ± 0.13 mmol/l, p = 0.026). Presence of TT genotype negatively correlated with BMD-Zscore (r = -0.28, p = 0.04), and positively with frequency of LBMD (r = 0.3, p = 0.037). Boy with GG Cdx2 genotype had lower total Ca (GG = 2.3 ± 0.17 mmol/l, GA+AA = 2.43 ± 0.17 mmol/l, p = 0.004) compare with carriers of A allele. Pubertal boys (Tanner IV-V) with GG had higher CTX (GG = 1.75 ± 0.11 ng/ml, GA+AA = 1.06 ± 0.07 ng/ml, p = 0.04.

Full Text Available Abstract Background Low- to middle-income countries are undergoing a health transition with non-communicable diseases contributing substantially to disease burden, despite persistence of undernutrition and infectious diseases. This study aimed to investigate the prevalence and patterns of stunting and overweight/obesity, and hence risk for metabolic disease, in a group of children and adolescents in rural South Africa. Methods A cross-sectional growth survey was conducted involving 3511 children and adolescents 1-20 years, selected through stratified random sampling from a previously enumerated population living in Agincourt sub-district, Mpumalanga Province, South Africa. Anthropometric measurements including height, weight and waist circumference were taken using standard procedures. Tanner pubertal assessment was conducted among adolescents 9-20 years. Growth z-scores were generated using 2006 WHO standards for children up to five years and 1977 NCHS/WHO reference for older children. Overweight and obesity for those 2 for overweight and obesity respectively were used for those ≥ 18 years. Waist circumference cut-offs of ≥ 94 cm for males and ≥ 80 cm for females and waist-to-height ratio of 0.5 for both sexes were used to determine metabolic disease risk in adolescents. Results About one in five children aged 1-4 years was stunted; one in three of those aged one year. Concurrently, the prevalence of combined overweight and obesity, almost non-existent in boys, was substantial among adolescent girls, increasing with age and reaching approximately 20-25% in late adolescence. Central obesity was prevalent among adolescent girls, increasing with sexual maturation and reaching a peak of 35% at Tanner Stage 5, indicating increased risk for metabolic disease. Conclusions The study highlights that in transitional societies, early stunting and adolescent obesity may co-exist in the same socio-geographic population. It is likely that this profile

Glanzmann thrombasthenia (GT) is a rare inherited platelet disorder that is characterized by spontaneous or postprocedural bleeding. The diagnosis of GT depends on identifying the dysfunction of the platelets. The aim of this study was to compare a whole blood impedance Multiplate analyzer (MEA) with the standard method, light transmission aggregometry (LTA) in diagnosis of GT. Fifteen patients with GT were assessed on MEA and LTA using arachidonic acid (ASPI: 15 mm), (TRAP: 1 mm), collagen (100 μg/mL), ADP (0.2 mm), and ristocetin (Risto: 10 mg/mL). Whole blood samples were collected in sodium citrate and hirudin vacuum, blood collection tubes and tested within 4 h. Platelet-rich plasma was used for LTA using platelet agonists (ristocetin 1.5 mg/mL) (arachidonic acid 0.5 mg/mL) (ADP 2.5 mg/mL) and (collagen 1 mg/mL). The platelet count and PFA-100 results were (average and SD) 319 ± 93 × 10(9) L and 252 ± 34 s, respectively. Flow cytometry analysis showed that all samples are positive for CD42a and CD42b, whereas 9/15 samples were negative for CD61 and CD41. The other six patients had either partial or full expression of CD61/CD41. Aggregation analysis using both methods showed that all samples had no aggregation response to any of the agonists used apart from six samples which, using only the MEA, showed minimal aggregation in response to collagen (average = 14.3 ± 7 μg, which may suggest ability to detect qualitative abnormality of GPIIb/IIIa). These results suggest that the MEA is sensitive for the detection of Glanzmann thrombasthenia. Furthermore, MEA may also be able to differentiate between the subtypes of Glanzmann thrombasthenia. © 2014 John Wiley & Sons Ltd.

Here, we present the results of a pilot study of 10 adults with ADHD participating in short-term individual ­cognitive-behavioral therapy (CBT, 9 adults participating in cognitive training (CT, and 10 controls. Self-report ­questionnaires, independent evaluations, and computerized neurocognitive testing were ­collected before and after the treatments to evaluate change. There were distinctive pre-hypotheses regarding the treatments, and therefore the statistical comparisons were conducted in pairs: CBT vs control, CT vs control, and CBT vs CT. In a combined ADHD symptom score based on self-reports, 6 participants in CBT, 2 in CT and 2 controls improved. Using independent evaluations, improvement was found in 7 of the CBT participants, 2 of CT ­participants and 3 controls. There was no treatment-related improvement in cognitive performance. Thus, in the CBT group, some encouraging improvement was seen, although not as clearly as in ­previous research with longer interventions. In the CT group, there was improvement in the trained tasks but no generalization of the improvement to the tasks of the neurocognitive testing, the ­self-report questionnaires, or the independent evaluations. These preliminary results warrant further studies with more participants and with more elaborate cognitive testing.Keywords: CBT, attention-deficit/hyperactivity disorder, cognitive testing, non-­pharmacological treatments

2017-07-01

The spreading of a cap-shaped spherical droplet of non-Newtonian power-law liquids, both shear-thickening and shear-thinning liquids, that completely wet a spherical substrate is theoretically investigated in the capillary-controlled spreading regime. The crater-shaped droplet model with the wedge-shaped meniscus near the three-phase contact line is used to calculate the viscous dissipation near the contact line. Then the energy balance approach is adopted to derive the equation that governs the evolution of the contact line. The time evolution of the dynamic contact angle θ of a droplet obeys a power law θ∼t^{-α} with the spreading exponent α, which is different from Tanner's law for Newtonian liquids and those for non-Newtonian liquids on a flat substrate. Furthermore, the line-tension dominated spreading, which could be realized on a spherical substrate for late-stage of spreading when the contact angle becomes low and the curvature of the contact line becomes large, is also investigated.

Youth use of ultraviolet-emitting indoor tanning beds represents a present and emerging public health crisis. Nearly 30% of white female high school students report tanning indoors, and a quarter of high school tanners have used a tanning bed more than 20 times in the past year. Despite the significant health risks of tanning beds, including potentially deadly melanoma and eye problems, limited actions have been taken in the U.S. to protect youth. Tobacco control policies and campaigns, which have sharply reduced youth smoking, may provide a useful framework to control indoor tanning among young people. This article describes several evidence-based tobacco control strategies with potential applicability to indoor tanning within the context of the U.S. Further, current tobacco control policies and current indoor tanning policies in the U.S. are compared, and recommendations on how to curtail youth indoor tanning are discussed.

Summary Identification of risk factors for indoor tanning may ultimately aid the development of better indoor tanning prevention strategies, which is pertinent given the association between indoor tanning and skin cancer. This study aimed to examine the relationship between seasonal sleep change and indoor tanning. Women tanners (N= 139) completed self-report measures including items relating to seasonal sleep changes, seasonal affective disorder (SAD), reasons for tanning, tanning during the winter months, and the Tanning Pathology Scale (TAPS), which measures problematic tanning motives and symptoms of tanning dependence. It was hypothesized that seasonal sleep change and SAD would be associated with greater indoor tanning during the winter, more tanning to improve mood and to relax, and higher scores on the TAPS. Findings indicated that more seasonal sleep change was associated with tanning to improve mood and higher scores on the TAPS. Similarly, the presence of SAD was related to tanning to improve mood, tanning to relax, and more problematic tanning. PMID:25730744

The problem of low complexity, close to optimal, channel decoding of linear codes with short to moderate block length is considered. It is shown that deep learning methods can be used to improve a standard belief propagation decoder, despite the large example space. Similar improvements are obtained for the min-sum algorithm. It is also shown that tying the parameters of the decoders across iterations, so as to form a recurrent neural network architecture, can be implemented with comparable results. The advantage is that significantly less parameters are required. We also introduce a recurrent neural decoder architecture based on the method of successive relaxation. Improvements over standard belief propagation are also observed on sparser Tanner graph representations of the codes. Furthermore, we demonstrate that the neural belief propagation decoder can be used to improve the performance, or alternatively reduce the computational complexity, of a close to optimal decoder of short BCH codes.

Instanton-based techniques for analysis and reduction of error floors of LDPC codes

We describe a family of instanton-based optimization methods developed recently for the analysis of the error floors of low-density parity-check (LDPC) codes. Instantons are the most probable configurations of the channel noise which result in decoding failures. We show that the general idea and the respective optimization technique are applicable broadly to a variety of channels, discrete or continuous, and variety of sub-optimal decoders. Specifically, we consider: iterative belief propagation (BP) decoders, Gallager type decoders, and linear programming (LP) decoders performing over the additive white Gaussian noise channel (AWGNC) and the binary symmetric channel (BSC). The instanton analysis suggests that the underlying topological structures of the most probable instanton of the same code but different channels and decoders are related to each other. Armed with this understanding of the graphical structure of the instanton and its relation to the decoding failures, we suggest a method to construct codes whose Tanner graphs are free of these structures, and thus have less significant error floors.

This report presents results of a DARPA/MTO Composite CAD Project aimed to develop a comprehensive microsystem CAD environment, CFD-ACE+ Multiphysics, for bio and microfluidic devices and complete microsystems. The project began in July 1998, and was a three-year team effort between CFD Research Corporation, California Institute of Technology (CalTech), University of California, Berkeley (UCB), and Tanner Research, with Mr. Don Verlee from Abbott Labs participating as a consultant on the project. The overall objective of this project was to develop, validate and demonstrate several applications of a user-configurable VLSI-type mixed-dimensionality software tool for design of biomicrofluidics devices and integrated systems. The developed tool would provide high fidelity 3-D multiphysics modeling capability, l-D fluidic circuits modeling, and SPICE interface for system level simulations, and mixed-dimensionality design. It would combine tools for layouts and process fabrication, geometric modeling, and automated grid generation, and interfaces to EDA tools (e.g. Cadence) and MCAD tools (e.g. ProE).

In this work, we present a series of solutions for combined electro-osmotic and pressure-driven flows of viscoelastic fluids in microchannels. The solutions are semi-analytical, a feature made possible by the use of the Debye-Hückel approximation for the electrokinetic fields, thus restricted to cases with small electric double-layers, in which the distance between the microfluidic device walls is at least one order of magnitude larger than the electric double-layer thickness. To describe the complex fluid rheology, several viscoelastic differential constitutive models were used, namely, the simplified Phan-Thien-Tanner model with linear, quadratic or exponential kernel for the stress coefficient function, the Johnson-Segalman model, and the Giesekus model. The results obtained illustrate the effects of the Weissenberg number, the Johnson-Segalman slip parameter, the Giesekus mobility parameter, and the relative strengths of the electro-osmotic and pressure gradient-driven forcings on the dynamics of these viscoelastic flows.

Predicting new ordered phases in metallic alloys is a productive line of inquiry because configurational ordering in an alloy can dramatically alter their useful material properties. One is able to infer the existence of an ordered phase in an alloy using first-principles calculated formation enthalpies.ootnotetextG. L. W. Hart, ``Where are Nature's missing structures?,'' Nature Materials 6 941-945 2007 Using this approach, we have been able to identify stable (i.e. lowest energy) orderings in a variety of binary metallic alloys. Many of these phases have been observed experimentally in the past, though others have not. In pursuit of several of the missing structures, we have characterized potential orderings in PtCd, PtPd and PtMo alloys using synchrotron x-ray powder diffraction and symmetry-analysis tools.ootnotetextB.

We report a study on the ion-size dependent electroosmosis of viscoelastic fluids in microfluidic channels with interfacial slip. Here, we derive an analytical solution for the potential distribution in a parallel plate microchannel, where the effects of finite sized ionic species are taken into account by invoking the free energy formalism. Following this, a purely electroosmotic flow of a simplified Phan-Thien-Tanner (sPTT) fluid is considered. For the sPTT model, linear, quadratic, and exponential kernels are chosen for the stress coefficient function describing its viscoelastic nature across various ranges of Deborah number. The theoretical framework presented in our analysis has been successfully compared with experimental results available in the literature. We believe that the implications of the considered effects on the net volumetric throughput will not only provide a deeper theoretical insight to interpret the electrokinetic data in the presence of ionic species but also serve as a fundamental design tool for novel electrokinetically driven lab-on-a-chip biofluidic devices.

Tanning is often prompted by appearance concerns, yet little is known about associations between tanning and other appearance-altering behaviors. In the current study, we examined potential correlates of indoor and outdoor tanning that, like tanning, may enhance appearance but present health risks. College students (N = 284; Mage = 20.14, SD = 3.39) completed a survey. The main outcome measures were indoor tanning and outdoor sunbathing. Participants also answered questions pertaining to piercings and tattoos, healthy and unhealthy dieting behaviors, cigarette smoking, and interest in cosmetic surgery and enhancements. Results indicate that indoor tanners were more likely to have piercings, tattoos, to engage in healthy dieting behaviors, and to express interest in cosmetic enhancements. Outdoor sunbathers were more interested in cosmetic enhancements than non-outdoor sunbathers, and female outdoor sunbathers reported more unhealthy dieting behaviors than male outdoor sunbathers. These findings provide evidence for college students' engagement in a constellation of appearance-oriented risk behaviors.

This essay recovers organized opposition to the National Health Service (NHS) by considering the Fellowship for Freedom in Medicine (FFM), a conservative organization of doctors who challenged the 'Sacred Cow' of nationalized healthcare in the 1950s and 1960s. While there has been little interest in anti-NHS politics because of shortcomings in the institution's historiography, this study suggests ways a new history of the service can be written. Central to that project is taking the broader ideological and emotive quality of the NHS seriously, and appreciating the way, for all sides of the political spectrum, as well as the general public, the service has always been a contested symbol of post-war British identity. This essay argues that two NHS 'crises'--panics over costs, and disillusionment within general practice--were not merely disagreements over budgets and pay-packets but politically charged moments infused with conservative anxieties over Britain's post-war trajectory. The FFM imagined the NHS as an economically dangerous bureaucratic machine that crushed medical independence and risked pushing the country towards dictatorship. Allies within the Conservative Party, private health insurance industry, and free-market 'think-tanks' worked with the FFM to challenge defences of both the service's operation and meaning. To appreciate why the NHS remains 'the closest thing the English have to a religion', one must consider the apostates as well as the faithful.

Indoor tanning is prevalent among young adults and women and is associated with increased risk of melanoma. Evidence suggests that indoor tanners may be more inclined to adopt poor photoprotective practices that further increase their risk of skin cancer; however, gaps in the literature exist in young adults and by indoor tanning frequency. To examine the association between indoor tanning frequency and behaviors related to skin cancer prevention and to investigate whether these associations vary by age group or sex. Cross-sectional population-based study of US 2015 National Health Interview Survey data including 10 262 non-Hispanic white adults aged 18 to 60 years without a history of skin cancer. Rare/never use of sunscreen, protective clothing, shade; multiple sunburns within the past year; previous full-body skin examination. Of the 10 262 individuals in our study population (49% female; median age, 39 y), 787 (7.0%) reported having tanned indoors in the past year. Among individuals aged 18 to 34 years, frequent indoor tanners (≥10 times in the past year) were more likely to report never/rare use of protective clothing (adjusted prevalence ratio [aPR], 1.28; 95% CI, 1.10-1.49) and shade (aPR, 1.32; 95% CI, 1.03-1.70), compared with individuals who did not tan indoors. Among women aged 18 to 60 years, those who frequently tanned indoors were more likely to rarely/never use sunscreen (aPR, 1.34; 95% CI, 1.11-1.62), protective clothing (aPR, 1.27; 95% CI, 1.15-1.42), and shade (aPR, 1.54; 95% CI, 1.25-1.90) on a warm sunny day, as well as more likely to report multiple sunburns in the past year (aPR, 1.21; 95% CI, 1.00-1.45) compared with those who did not tan indoors. Individuals who tanned indoors in the past year were not significantly more likely to have undergone a previous full-body skin examination in any subpopulation examined. Individuals who tan indoors often exhibited a concurrent tendency to sunburn, avoid sun protection, and avoid skin cancer

Is a school-based physical activity intervention effective for increasing tibial bone strength in boys and girls?

Macdonald, Heather M; Kontulainen, Saija A; Khan, Karim M; McKay, Heather A

2007-03-01

This 16-month randomized, controlled school-based study compared change in tibial bone strength between 281 boys and girls participating in a daily program of physical activity (Action Schools! BC) and 129 same-sex controls. The simple, pragmatic intervention increased distal tibia bone strength in prepubertal boys; it had no effect in early pubertal boys or pre or early pubertal girls. Numerous school-based exercise interventions have proven effective for enhancing BMC, but none have used pQCT to evaluate the effects of increased loading on bone strength during growth. Thus, our aim was to determine whether a daily program of physical activity, Action Schools! BC (AS! BC) would improve tibial bone strength in boys and girls who were pre- (Tanner stage 1) or early pubertal (Tanner stage 2 or 3) at baseline. Ten schools were randomized to intervention (INT, 7 schools) or control (CON, 3 schools). The bone-loading component of AS! BC included a daily jumping program (Bounce at the Bell) plus 15 minutes/day of classroom physical activity in addition to regular physical education. We used pQCT to compare 16-month change in bone strength index (BSI, mg2/mm4) at the distal tibia (8% site) and polar strength strain index (SSIp, mm3) at the tibial midshaft (50% site) in 281 boys and girls participating in AS! BC and 129 same-sex controls. We used a linear mixed effects model to analyze our data. Children were 10.2+/-0.6 years at baseline. Intervention boys tended to have a greater increase in BSI (+774.6 mg2/mm4; 95% CI: 672.7, 876.4) than CON boys (+650.9 mg2/mm4; 95% CI: 496.4, 805.4), but the difference was only significant in prepubertal boys (p=0.03 for group x maturity interaction). Intervention boys also tended to have a greater increase in SSIp (+198.6 mm3; 95% CI: 182.9, 214.3) than CON boys (+177.1 mm3; 95% CI: 153.5, 200.7). Change in BSI and SSIp was similar between CON and INT girls. Our findings suggest that a simple, pragmatic program of daily activity

Unsteady viscoelastic flows were studied using the finite element method in this work. The Phan-Thien–Tanner (PTT) model was used to represent the rheological behavior of viscoelastic fluids. To effectively describe the microscale effects, the slip boundary condition and surface tension were added to the mathematical model for melt flow in micro-injection molding. The new variational equation of pressure, including the viscoelastic parameters and slip boundary condition, was generalized using integration by parts. A computer code based on the finite element method and finite difference method was developed to solve the melt flow problem. Numerical simulation revealed that the melt viscoelasticity plays an important role in the prediction of melt pressure, temperature at the gate and the succeeding melt front advancement in the cavity. Using the viscoelastic model one can also control the rapid increase in simulated pressure, temperature, and reduce the filling difference among different cavities. The short shot experiments of micro-motor shaft showed that the predicted melt front from the viscoelastic model is in fair agreement with the corresponding experimental results

To evaluate which factors are associated with alterations in pubertal development in pediatric patients with leukemia in the surveillance phase. A case-control study was carried out, including patients aged 8-14 years with diagnosis of acute lymphoblastic leukemia under surveillance. Demographic data were collected, age at diagnosis, type of leukemia, risk of leukemia, duration and type of treatment received, time of surveillance phase; and pubertal development was assessed by Tanner stage, bone age, pelvic ultrasound for women, and LH levels. Fisher's exact test and Mann-Whitney U-test were used. Twenty-five pediatric patients with a diagnosis of acute lymphoblastic leukemia between 8 and 14 years of age with a median of 8 were included, only 4 (16%) presented pubertal alterations, 1 had pubertal delay and 3 advanced puberty. The history of radiotherapy was related to pubertal alterations (p = 0.03). The antecedent of having received radiotherapy as part of the treatment in patients with acute lymphoblastic leukemia is a risk factor for developing pubertal abnormalities.

A 4-(o-chlorophenyl)-2-aminothiazole (CPAT) has been synthesized by reacting o-chloroacetophenone, iodine and thiourea under microwave irradiation as a green chemistry approach. The reactions proceed selectively and within a couple of minutes giving high yields of the products. The compound was characterized by elemental, spectral (UV-visible, IR, NMR and GC-MS), XRD and thermal analyses. The TG curve of the compound was analyzed to calculate various kinetic parameters (n, E, Z, ΔS and ΔG) by using Coats-Redfern (C.R.), MacCallum-Tanner (M.T.) and Horowitz-Metzger (H.M.) method. The compound was tested for the evaluation of antibacterial activity against B. subtilis and E. coli and antifungal activity against A. niger and C. albicans. The compound was evaluated for their in vitro nematicidal activity on plant parasitic nematode Meloidogyne javanica and molluscicidal activity on fresh water helminthiasis vector snail Lymnea auricularia. The compound is biologically active in very low concentration. X-ray diffraction study suggests a triclinic crystal system for the compound.

Full Text Available Vegetable tannins are found in several forest species. Actually, the Northeast Brazilian tanners have, on Anadenanthera colubrina var. cebil, their only source of vegetable tannins. This study aimed to evaluate the tanning capacity of tannins extracted from four vegetable species of Brazilian Semi-arid region, seeking to make possible the diversification of species to be used in tannings in the region. Thus, physical and mechanical characteristics of bovid treated skins with extract tannic of Anadenanthera colubrina var. cebil, Anacardium occidentale, Mimosa tenuiflora and Mimosa arenosa were analyzed. The bovid skins were tanned with extracted tannins of those species and compared to tanned skins by tannins of Acacia mearnsii (“Seta Natur” commercial tannin. The samples of tanned skins were submitted to tension, lengthening and progressive tear resistance tests. Good results were verified to tanned skins by Mimosa tenuiflora and Mimosa arenosa. Due to the abundance of these species in Brazilian Semi-arid region, they showed potential to exploration of tannins. However, researches are necessaries to indicate the best forms of application of obtained tannins.

Herein, we present a 14-year-old patient with short stature (134 cm) referred from Paediatrics to our department for complementary evaluation since growth hormone (GH) treatment failed to show any improvement. He was born premature and small for gestational age. Genital examination classified the patient as Tanner I–II with small penis and testicular size for his age. Biochemical analyses revealed normal GH levels with low serum insulin-like growth factor-1 (IGF-1). Molecular diagnosis confirmed several mutations in IGF1R and IGFALS, and so he was diagnosed with Laron Syndrome or GH insensibility and treated with IGF-1 substitutive therapy. Learning points: Evaluation of the GH/IGF-1 axis when short stature does not respond to conservative treatment must be included in the ordinary practice. Laron Syndrome real incidence should be calculated once undiagnosed cases arise, as treatment, due to lack of market, is unaffordable. Even when adulthood is reached, and no longitudinal growth can be achieved, still IGF-1 treatment in Laron Syndrome patients should be pursued as metabolic and protective derangements could arise.

The potential carcinogenic risk of tanning beds: clinical guidelines and patient safety advice

International Nuclear Information System (INIS)

Mogensen, Mette; Jemec, Gregor BE

2010-01-01

In 2009, the WHO listed ultraviolet (UV) radiation as a group 1 carcinogen. In spite of this, each year, millions of people tan indoor in Western countries. The aim of this review is to summarize evidence of tanning bed carcinogenesis and to present guidelines for use of tanning beds and patient safety advice. A narrative review of the literature was conducted based on both PubMed and Medline searches and on literature review of the retrieved papers. Use of indoor tanning beds represents a significant and avoidable risk factor for the development of both melanoma and nonmelanoma skin cancers. Frequent tanners are more often adolescent females. Tanning beds have additional potential adverse effects such as burns, solar skin damage, infection, and possibly also addictive behavior. The effort in preventing UV light-induced carcinogenesis should currently be aimed at developing new strategies for public health information. Tanning beds are one preventable source of UV radiation. In the majority of people solar UV radiation continues to be the major factor and therefore anti-tanning campaigns must always include sunbathers

Young, non-Hispanic white females represent the population most likely to use indoor tanning facilities. This population may be at increased risk of skin cancer as recent meta-analyses support a strong association between cutaneous malignancy and indoor tanning. Public perception of the purported health benefits of indoor tanning may be partially to blame for the popularity of tanning salons as a desire to prepare skin prior to sun exposure is among the most commonly cited motivations for indoor tanning. Improving education and counseling to address misconceptions regarding tanning safety will require the participation of healthcare providers for both physical and psychological screenings as well as for information dissemination. This review presents the association between tanning bed use and skin cancer, biological effects of UV radiation exposure, UV burden associated with tanning devices, public perception of tanning, demographic and psychological profile of indoor tanners, and current legislation regulating tanning bed use.

Full Text Available Hydatidosis is a common infestation caused by Echinococcus spp. Solitary hydatid cyst of the lung is not uncommon but coexistence of two or more pulmonary cysts are less common. These cysts may drain into the bronchial tree or very rarely into the pleural cavity which causes a poor outcome. Certain people such as slaughters, tanners, stockbreeders, shepherds, butchers, veterinarians and all whose job makes them to work closely with animals are at higher risk of the infection and developing echinococcosis. Herein, we present a 14-year-old shepherd who developed severe chest pain and hydropneumothorax following a minor trauma to his chest. He had two pulmonary hydatid cysts, one of which drained to the left pleural cavity and caused the symptoms. Another cyst was complicated during his hospital course. The patient was treated surgically, received albendazole and discharged home uneventfully. A high index of suspicion is of utmost importance for the correct diagnosis and treatment of hydatid disease in hyperendemic areas and in those whose occupation might put them at a higher risk of contraction of hydatid disease.

Clinical characteristics and laboratory and cabinet findings (hormone levels, bone age, pelvic ultrasound) were determined in a sample of 39 patients diagnosed with central precocious puberty (CPP) who started treatment with leuprolide acetate (LPA). The cross-sectional observational study was developed at the Hospital Nacional de Ninos 'Dr. Carlos Saenz Herrera' during the period 2004 and 2009. The chronological age of patients with CPP was specified at the time of diagnosis and to start treatment with LPA. Epidemiological characteristics (sex, origin) were described in patients with CPP. Bone age with respect to chronological age was identified in patients with CPP. Sexual maturity of patients with CPP was established by the Tanner scale. The hormone levels of estrogen, testosterone, luteinizing hormone and follicle stimulating hormone were specified in patients with CPP. The etiology was determined in patients with CPP treated with LPA. The adverse effects of treatment with LPA were described. Anthropometric measurements were detailed. The heredo-familial antecedents of precocious puberty were established in patients with diagnosis of CPP. The size of the pelvic organs was evaluated by pelvic ultrasound [es

Full Text Available We describe the case of a 6.5-year-old girl with central precocious puberty (CPP, which signifies the onset of secondary sexual characteristics before the age of eight in females and the age of nine in males as a result of stimulation of the hypothalamic-pituitary-gonadal axis. Her case is likely related to her adoption, as children who are adopted internationally have much higher rates of CPP. She had left breast development at Tanner Stage 2, adult body odor, and mildly advanced bone age. In order to halt puberty and maximize adult height, she was prescribed a gonadotropin releasing hormone analog, the first line treatment for CPP. She was administered Lupron (leuprolide acetate Depot-Ped (3 months intramuscularly. After her second injection, she developed swelling and muscle pain at the injection site on her right thigh. She also reported an impaired ability to walk. She was diagnosed with muscle fibrosis. This is the first reported case of muscle fibrosis resulting from Lupron injection.

The introduction of the Health and Social Care Bill (2011) changed the role of GPs to include commissioning of health services. Aim This study aimed to identify any differences in the media portrayal of GPs before and after the introduction of the Bill. We retrospectively searched four British newspapers over the period 2009-2013 using the media database Nexis. In order to directly compare the findings of the study with the work of Tanner et al., articles relating to GP pay were analysed using thematic analysis. Themes were identified and each article was scored to determine whether it portrayed GPs positively or negatively. GPs were portrayed slightly less negatively after the introduction of the Bill. The theme of 'high salaries' persisted despite reference to 'pay freezes'. References to decreased trust in the patient-doctor relationship appeared after the introduction of the Bill. Negative portrayal of GP pay has continued and a lack of trust in GPs has started to be portrayed. This trend may exacerbate the low morale amongst the profession and difficulties in recruiting and retaining GPs.

We examined the differences in physical self-perception and motivation toward physical activity in early- and mid-adolescent girls. Body Mass Index (BMI) and pubertal status, assessed by means of the Tanner scale, were collected in 11-year-old (n=74) and 13-year-old girls (n=60). The assessment included six scales from the Physical Self-Description Questionnaire, the Physical Activity Enjoyment Scale, and the Situational Intrinsic Motivation Scale. Age differences emerged, with older girls showing a poorer physical perception and lower scores in intrinsic motivation and enjoyment of physical activity. In the subsample of 11-year-olds, findings showed that more developed girls reported a poorer physical perception on the scales of body fat, global physical self-concept, and appearance, and a lower score in the PACES positive scale. Results underscore the need to promote interventions aimed at encouraging active lifestyles among children and adolescent girls, in order to prevent overweight prior to pubertal onset.

To build this process it is necessary to consult customers for preferences, build familiarity and knowledge to build a relationship and conduct business in a customized fashion. The process takes every opportunity to build customer satisfaction with each customer contact. It is an important process to have, since customers today are more demanding, sophisticated, educated and comfortable speaking to the company as an equal (Belk, 2003). Customers have more customized expectations so they want to be reached as individuals (Raymond and Tanner, 1994). Also, a disproportionate search for new business is costly. The cost to cultivate new customers is more than maintaining existing customers (Cathcart, 1990). Other reasons that customer retention is necessary is because many unhappy customers will never buy again from a company that dissatisfied them and they will communicate their displeasure to other people. These dissatisfied customers may not even convey their displeasure but without saying anything just stop doing business with that company, which may keep them unaware for some time that there is any problem (Cathcart, 1990).

Full Text Available Convolutional codes are comprehensively used as Forward Error Correction (FEC codes in digital communication systems. For decoding of convolutional codes at the receiver end, Viterbi decoder is often used to have high priority. This decoder meets the demand of high speed and low power. At present, the design of a competent system in Very Large Scale Integration (VLSI technology requires these VLSI parameters to be finely defined. The proposed asynchronous method focuses on reducing the power consumption of Viterbi decoder for various constraint lengths using asynchronous modules. The asynchronous designs are based on commonly used Quasi Delay Insensitive (QDI templates, namely, Precharge Half Buffer (PCHB and Weak Conditioned Half Buffer (WCHB. The functionality of the proposed asynchronous design is simulated and verified using Tanner Spice (TSPICE in 0.25 µm, 65 nm, and 180 nm technologies of Taiwan Semiconductor Manufacture Company (TSMC. The simulation result illustrates that the asynchronous design techniques have 25.21% of power reduction compared to synchronous design and work at a speed of 475 MHz.

Diffusion-weighted imaging (DWI) is a magnetic resonance imaging (MRI) technique that was established in the clinical routine primarily for the detection of brain ischemia. In the past 15 years its clinical use has been extended to oncological radiology, as tumor and metastases can be depicted in DWI due to their hypercellular nature. The basis of DWI is the Stejskal-Tanner experiment. The diffusion properties of tissue can be visualized after acquisition of at least two diffusion-weighted series using echo planar imaging and a specific sequence of gradient pulses. The use of DWI in prostate MRI was reported to be one of the first established applications that found its way into internationally recognized clinical guidelines of the European Society of Urological Radiology (ESUR) and the prostate imaging reporting and data system (PI-RADS) scale. Due to recently reported high specificity and negative predictive values of 94 % and 92 %, respectively, its regular use for breast MRI is expected in the near future. Furthermore, DWI can also reliably be used for whole-body imaging in patients with multiple myeloma or for measuring the extent of bone metastases. New techniques in DWI, such as intravoxel incoherent motion imaging, diffusion kurtosis imaging and histogram-based analyses represent promising approaches to achieve a more quantitative evaluation for tumor detection and therapy response.

Objectives: To evaluate deferiprone related knee arthropathy in patients with fi-thalassemia major undergoing chelation therapy with deferiprone (LI). Materials and Methods. This study included 40 patients with β- thalassemia major on deferiprone; their ages ranged from 8 to 18 years with a mean age of 12.6 ± 3 years. Forty age and sex matched patients on desferal served as controls. Patients were subjected to clinical knee joint examination using the modified hemophilia joint health score (JHS), bilateral knee joint X-ray and bilateral knee joint ultrasound. Twenty patients of the deferiprone group with positive knee joint ultrasound findings were subjected to knee MRI. Data collected included age, sex, transfusion index, chelation history (dose, duration, and adverse effects), history of splenectomy and symptoms of knee or other joints arthropathy. Weight, height, BMI and Tanner staging of the patients were recorded. Laboratory investigations included CBC, ALT, serum ferritin, viral hepatitis markers (B,C) and echocardiography. Results: Among deferiprone group; 25 patients (62.5%) had knee symptoms while; 93.3% of the asymptomatic patients had evidence of knee joint affection by JHS compared to 17 symptomatic patients (42.5%) among desferal group (ρ> 0.05). Among deferiprone group 7 patients (17.5%) had symptoms of other joints arthropathy. Knee symptoms were more prevalent with longer duration of deferiprone therapy (ρ<0.05), knee joint effusion in US (ρ< 0.05) and Higher platelet count (ρ<0.05), while in desferal group it was related to poor compliance (ρ< 0.01) and higher serum ferritin levels (ρ=<0.01). JHS ranged from 0-33 with 39 (97.5%) affected patients. JHS was positively correlated to age, weight, height, BMI, Tanner staging and platelet count (ρ<0.01), and negatively correlated to transfusion index (ρ<0.01) with no significant correlation to ultrasound or MRI findings. JHS was higher among splenectomized patients in both groups (ρ<0.01). No

Knowledge of bone age in achondroplasia is required for the prediction of adult height, timings of limb lengthening, and epiphysiodesis procedures. The purpose of this investigation was to determine the differences in skeletal age in achondroplasia and a control population with the Tanner-Whitehouse 3 method using the RUS score and to determine the right age for the interventional procedure for limb lengthening procedure or deformity correction in these patients. Left hand radiographs of 34 patients (age range, 5-18 years) with achondroplasia were evaluated for skeletal age using the RUS scoring system, which were compared with the left hand radiographs of 41 patients (age range, 5-18 years) without achondroplasia measuring skeletal age. The difference in chronological age and RUS bone age were evaluated statistically according to gender and age group. In the achondroplasia group, chronological age were 10.5{+-}4.3 years for males and 10.1{+-}3.6 years for females and RUS bone age were 9.2{+-}4.0 years for males and 8.9{+-}3.4 years for females, which showed statistically significantly difference (males p=0.0003 and females p < 0.0001), while in the control group, chronological age were 11.1{+-}2.9 years for males and 10.7{+-}3.4 years for females and RUS bone age were 11.2{+-}3.4 years for males and 10.7{+-}3.3 years for females, which did not show statistically significantly difference (males p=0.54 and females p=0.76). Our finding suggested a delay of 1.4 years for males and 1.2 years for females in the maturation of bone in achondroplasia patients. Difference between chronological age and RUS bone age was 0.9{+-}1.1 for <10 years and 1.6{+-}0.9 for >10 years in the study group, while 0.1{+-}1.1 for <10 years and -0.2 {+-} 0.6 for >10 years in the control group, which also showed >statistically significant difference (<10 years p=0.04 and >10 years p<0.0001). These differences indicate that there was a delay in the maturation of bones by 1 year in the group <10

Objective: To investigate possible effect of 6 obesity-associated SNPs in contribution to central obesity and examine whether there is an interaction in the 6 SNPs in the cause of central obesity in school-aged children in China. Methods: A total of 3 502 school-aged children who were included in Beijing Child and Adolescent Metabolic Syndrome (BCAMS) Study were selected, and based on the age and sex specific waist circumference (WC) standards in the BCAMS study, 1 196 central obese cases and 2 306 controls were identified. Genomic DNA was extracted from peripheral blood white cells using the salt fractionation method. A total of 6 single nucleotide polymorphisms ( FTO rs9939609, MC4R rs17782313, BDNF rs6265, PCSK1 rs6235, SH2B1 rs4788102, and CSK rs1378942) were genotyped by TaqMan allelic discrimination assays with the GeneAmp 7900 sequence detection system (Applied Biosystems, Foster City, CA, USA). Logistic regression model was used to investigate the association between 6 SNPs and central obesity. Gene-gene interactions among 6 polymorphic loci were analyzed by using the Generalized Multifactor Dimensionality Reduction (GMDR) method, and then logistic regression model was constructed to confirm the best combination of loci identified in the GMDR. Results: After adjusting gender, age, Tanner stage, physical activity and family history of obesity, the FTO rs9939609-A, MC4R rs17782313-C and BDNF rs6265-G alleles were associated with central obesity under additive genetic model ( OR =1.24, 95 %CI : 1.06-1.45, P =0.008; OR =1.26, 95 %CI : 1.11-1.43, P =2.98×10(-4); OR =1.18, 95 % CI : 1.06-1.32, P =0.003). GMDR analysis showed a significant gene-gene interaction between MC4R rs17782313 and BDNF rs6265 ( P =0.001). The best two-locus combination showed the cross-validation consistency of 10/10 and testing accuracy of 0.539. This interaction showed the maximum consistency and minimum prediction error among all gene-gene interaction models evaluated. Moreover, the

For practical use of an under-sodium viewer, the behavior of sodium wetting is investigated by modeling the reactive and non-reactive wetting of metallic-plated steels by liquid sodium to simulate sodium wetting. The non-reactive wetting simulation results showed good agreement with Tanner's law, in which the time dependencies of the droplet radius and contact angle are expressed as R N ∝ t 1/10 and θ∝ t -3/10 , respectively; therefore, the model was considered suitable for the simulation. To simulate reactive wetting, the model of fluid flow induced by the interfacial reaction was incorporated into the simulation of non-reactive wetting. The reactive wetting simulation results, such as the behavior of the precursor liquid film and central droplet, showed good agreement with sodium wetting experiments using thin Au plating at 250°C. An important result of the reactive wetting simulation is that the gradient of the reaction energy at the interface appeared on the new interface around the triple line, and that fluid flow was induced. This interfacial reactivity during sodium wetting of thin Au plating was enhanced by the reaction of sodium and nickel oxide through pinholes in the plating. (author)

The historian Fernand Braudel considered that geography dictates history because a certain region or a certain state requires a characteristic of its economic life. Commerce was often called in mercantilist period the blood that provides life of the nation. These data imply progress in terms of demographic beyond doubt, especially in the employment of the German minority living in the urban communes of the Banat Mountain. We retain the dual nature of their occupations, with farm work kept in the background, but the main plane dominated the gradual effect of industrial labour and business activities. Along with farmers, most Germans residing in villages and hamlets in the mountains of Banat were devoted to jobs in the service sector and small crafts area. They worked both as employers and employees in the stores and workshops in rural and urban areas where they resided. Working as sellers, barbers, blacksmiths, carpenters, tailors, butchers, tanners, plumbers, painters or as doctors, dentists, teachers, lawyers, they have contributed to the development of material and spiritual not only their own minority but of communities within which they were born and prospered.

Growth charts of human development.

Science.gov (United States)

van Buuren, Stef

2014-08-01

This article reviews and compares two types of growth charts for tracking human development over age. Both charts assume the existence of a continuous latent variable, but relate to the observed data in different ways. The D-score diagram summarizes developmental indicators into a single aggregate score measuring global development. The relations between the indicators should be consistent with the Rasch model. If true, the D-score is a measure with interval scale properties, and allows for the calculation of meaningful differences both within and across age. The stage line diagram describes the natural development of ordinal indicators. The method models the transition probabilities between successive stages of the indicator as smoothly varying functions of age. The location of each stage is quantified by the mid-P-value. Both types of diagrams assist in identifying early and delayed development, as well as finding differences in tempo. The relevant techniques are illustrated to track global development during infancy and early childhood (0-2 years) and Tanner pubertal stages (8-21 years). New reference values for both applications are provided. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Puberty can affect vitamin D levels. The goal of this study was to analyze the relation between vitamin D deficiency and puberty in obese Spanish children, along with the possible interrelation between vitamin D status and degree of insulin resistance. A cross-sectional study was carried out, in which clinical and biochemical data were gathered from 120 obese and 50 normal weight children between January 2011 and January 2013. Mean vitamin D levels were 19.5 and 31.6 ng/mL in obese pubertal and obese prepubertal children, respectively. About 75% of the obese pubertal subjects and 46% of the obese prepubertal subjects had vitamin D deficiency. Vitamin D levels were significantly lower in pubescent subjects compared with pre-pubescent subjects in summer, fall, and winter. There was no apparent relation between vitamin D levels and homeostasis model assessment index for insulin resistence (expressed in standard deviation score for sex and Tanner stage) in either puberty or pre-puberty. Puberty may be a risk factor for the vitamin D deficiency commonly found in the obese child population. This deficiency is not associated with higher insulin resistance in obese pubertal children compared with obese prepubertal children.

Full Text Available Swyer syndrome is caused by abnormal sex differentiation during the embryonic period, resulting in incomplete intrauterine masculinization and undifferentiated gonads. The current case report describes a patient with Swyer syndrome associated with stage 3 gonadal dysgerminoma who has survived for 23 years. At age 18, this patient sought assistance for primary amenorrhea from the Gynecological Services Department of the University of Brasília Hospital. A physical examination revealed that the patient was at Tanner stage 4 with respect to axillary hair, breasts, and pubic hair; she presented with a eutrophic vagina and a small cervix. She was treated with a combination of estrogens and progestogens to induce cycling. Approximately 4 years later, a complex tumor was found and resected; a histopathological analysis revealed that this tumor was a right adnexal dysgerminoma with peritoneal affection. The patient was also subjected to chemotherapy. Her follow-up has continued to the present time, with no signs of tumor recurrence. In conclusion, this report describes an extremely rare case in which Swyer syndrome was associated with ovarian dysgerminoma; relative to similar patients, the described patient has survived for an unusually prolonged time.

Full Text Available The importance of assessing precocious puberty, especially in boys, is not only due to the great complications it has for the affected patients, but also to the fatal underlying diseases. Therefore, children with central precocious puberty should first undergo neuroimaging. In this case study, we present a 9.5-year-old boy who was referred to Rasoul-e-Akram Medical Center with increased intracranial pressure, nausea/vomiting, and severe headache having begun three months earlier. The development of secondary sexual changes had started two years earlier, and had been neglected. His testes, penis, and pubic hair were at the fourth Tanner stage. He had elevated luteinizing and follicle stimulating hormones. Microscopic evaluation confirmed low-grade pilocytic astrocytoma WHO grade 1. Emergency brain surgery was conducted in which the brain was decompressed, and chemotherapy was started postoperatively. Two years after the surgery, he remains under chemotherapy, with obvious sexual maturation and a height of 154 cm. Training families and medical staff efficiently can help prevent the late diagnosis and treatment of precocious puberty and, as a result, help patients in their social life.

A matched case-control study was carried out to evaluate biological risk indicators for recurrent non-specific low back pain in adolescents. Adolescents with recurrent non-specific low back pain (symptomatic; n = 28; mean (SD) age 14.9 (0.7) years) and matched controls (asymptomatic; n = 28; age 14.9 (0.7) years) with no history of non-specific low back pain participated. Measures of stature, mass, sitting height, sexual maturity (Tanner self assessment), lateral flexion of the spine, lumbar sagittal plane mobility (modified Schober), hip range of motion (Leighton flexometer), back and hamstring flexibility (sit and reach), and trunk muscle endurance (number of sit ups) were performed using standardised procedures with established reliability. Backward stepwise logistic regression analysis was performed, with the presence/absence of recurrent low back pain as the dependent variable and the biological measures as the independent variables. Hip range of motion, trunk muscle endurance, lumbar sagittal plane mobility, and lateral flexion of the spine were identified as significant risk indicators of recurrent low back pain (plow back pain in a group of adolescents. These risk indicators identify the potential for exercise as a primary or secondary prevention method.

This project analyzes in greater detail the coded-wire-tag (CWT) returns of Priest Rapids Hatchery fall chinook for the years 1976--1989 initially begun by Hilborn et al. (1993a). These additional analyses were prompted by suggestions made by peer reviews of the initial draft report. The initial draft and the peer review comments are included in this final report (Appendices A and B). The statistical analyses paired Priest Rapids stock with potential downriver reference stocks to isolate in-river survival rates. Thirty-three potential reference stocks were initially examined for similar ocean recovery rates; the five stocks with the most similar recovery patterns (i.e., Bonneville Brights, Cowlitz, Gray's River, Tanner Creek, and Washougal) to the Priest Rapids stock were used in the subsequent analysis of in-river survival. Three alternate forms of multiple regression models were used to investigate the relationship between predicted in-river survival and ambient conditions. Analyses were conducted with and without attempts to adjust for smolt transportation at McNary Dam. Independent variables examined in the analysis included river flows, temperature, turbidity, and spill along with the total biomass of hatchery releases in the Columbia-Snake River Basin

Exposure and possible adverse effects of the Exxon Valdez oil spill (EVOS) at depth were studied between 1989 and 1991 on several species of crustaceans, molluscs, and finfish that are characterized by ontogenetic shifts in distribution from meroplanktonic larvae to benthic and demersal juveniles and adults. The authors approach was to search for (1) evidence of exposure to Exxon Valdez crude oil (EVC) at depth (generally between 20 to 150 m) and (2) measurable perturbations at both the individual and population levels. Primary species targeted were Tanner crab (Chionoecetes bairdi), several pandalid shrimps (Pandalus platyceros, P. hypsinotus, P. borealis), flathead sole (Hippoglossoides elassodon), and several bivalves including scallops (Chlamys rubida) and infaunal clams (Nuculana, Yoldia, and Macoma spp.). The survey design provided a comparison between variables measured in oiled bays around Knight Island and non-oiled bays at other locations within Prince William Sound. Polycyclic aromatic hydrocarbons (PAHs) of petrogenic origin were measured in all bays sampled in this study and levels of PAHs derived from EVC were elevated in the oiled bays following the spill, yet attenuated to less than 200 ng/g sediment by 1991. 95 refs., 22 figs., 6 tabs

Skeletal age has been studied and proved that for most elite athletes, it was coincident with the chronological ages when they were young. In order to explore the application of skeletal age in selecting sports talent, 32 athletes (female, chronological age 5-12 y) were chosen from the Gymnastics Training Base in this study. Their left hand-wrists were photographed with X-rays, and then the skeletal ages were estimated by Chinese version of the Tanner-Whitehouse Skeletal Maturity Assessment System. At the same time, their body shapes, functions, and sports ability were also measured. Results showed that 71.88% of the skeletal age was proportional to their chronological age (+/- 1 y); while 18.75% of the skeletal maturity was retarded by 1- 2 year, 9.37% of those was advanced more than 1 year. On the other hand, the body shape, functions and sports ability of the athletes were positively related with their skeletal maturity. This study proved that the determination of skeletal maturity is a reliable evaluation for selecting sports talent. A further study on the influence of gymnastics on the skeletal age is of great significance.

Full Text Available Methylphenidate is a commonly prescribed treatment for attention deficit hyperactivity disorder (ADHD. However, little is known about its adverse effects on the male reproductive system. We report a 20-year-old male patient whose chief complaint was of delayed puberty. He spoke in a high-pitched voice and complained of lack of body hair, impaired libido, inadequate erectile function, chronic fatigue, and low energy. He had been treated with methylphenidate as an infant and had continued treatment for 17 years. On examination, the patient was lean and visibly lacked facial or body hair. He further explained that he had never been able to grow underarm or facial hair and that he was often mistakenly considered a young teenager rather than a 20-year-old. The patient’s genitalia were categorized as Tanner Stage 2. Laboratory studies confirmed low serum follicle-stimulating hormone (FSH, luteinizing hormone (LH, and testosterone levels. The patient was given exogenous testosterone supplementation with pellets and human chorionic gonadotropin to maintain testicular size. After 4 months his symptoms improved and he demonstrated signs of puberty. Our goal is to further elucidate the possible impact of methylphenidate on the male reproductive system.

Dynamic wettability and contact angle hysteresis can be correlated to shed insight onto any solid-liquid interaction. Complex fluids are capable of altering the expected hysteresis and dynamic wetting behavior due to interfacial interactions. We report the effect of capillary number on the dynamic advancing and receding contact angles of surfactant-based nanocolloidal solutions on hydrophilic, near hydrophobic, and superhydrophobic surfaces by performing forced wetting and de-wetting experiments by employing the embedded needle method. A segregated study is performed to infer the contributing effects of the constituents and effects of particle morphology. The static contact angle hysteresis is found to be a function of particle and surfactant concentrations and greatly depends on the nature of the morphology of the particles. An order of estimate of line energy and a dynamic flow parameter called spreading factor and the transient variations of these parameters are explored which sheds light on the dynamics of contact line movement and response to perturbation of three-phase contact. The Cox-Voinov-Tanner law was found to hold for hydrophilic and a weak dependency on superhydrophobic surfaces with capillary number, and even for the complex fluids, with a varying degree of dependency for different fluids.

Introduction: Precise evaluation of the developmental stage of a child is not only an integral part of both diagnosis and treatment of paediatric patients; it is also essential in Forensic Medicine and Dentistry. Physiologic age can be estimated by somatic, sexual, skeletal and dental maturity. Aim: Investigate the relationship between the dental age (DA) and skeletal age (SA) of children and comparing it with the chronological age (CA). Materials and Methods: The dental age estimation methods of Schour and Massler (S&M), and Demirjian and Goldstien (D&G) and skeletal assessment methods of Greulich and Pyle (G&P), and Tanner et al., (TW2) were used to analyze the orthopantomograms and hand-wrist radiographs respectively of 150 healthy subjects within the age range of 5-15 y and compared with the Chronological Age. Statistical Analysis: Data collected was statistically analysed using the SPSS version 15.0 Statistical Analysis Software. For all tests p-value of <0.05 were considered statistically significance. Results: Dental age estimation techniques were found comparable and equally reliable as the skeletal age estimation methods. Strong correlations between dental and skeletal maturation were demonstrated. PMID:25386525

Isolated premature menarche is isolated or recurrent vaginal bleeding in a female in the absence of appropriate secondary sexual characters. Retrospective chart review of patients with premature menarche, followed by a telephone questionnaire. Charts of patients evaluated in the Pediatric Endocrine Clinic for premature vaginal bleeding from 1982-2013 were reviewed. Of 21 patients identified, 17 could be contacted. Five newly diagnosed patients were recruited during the course of the study. The median age at initial presentation was 7 years. Most patients presented with Tanner I sexual development. Some had more advanced breast staging, which regressed later. All had prepubertal baseline and stimulated gonadotropins. Most of the patients reported a single or few episodes of menses. Two reported continuation of irregular bleeding into adulthood. All reported an adult height within the midparental target height. Premature menarche in the absence of other appropriate secondary sexual characteristics is a benign entity. Most patients have a few isolated episodes of menses that stop spontaneously; some may continue to have periods into adulthood. Unlike true puberty, these patients do not demonstrate advanced skeletal maturation, and the adult height is normal. Fertility appears to be normal. © 2015 S. Karger AG, Basel.

We developed a new noninvasive technique to visualize the anatomical structure of the nerve fiber system in vivo, and named this technique magnetic resonance (MR) tractography and the acquired image an MR tractogram. MR tractography has two steps. One is to obtain diffusion-weighted images sensitized along axes appropriate for depicting the intended nerve fibers with anisotropic water diffusion MR imaging. The other is to extract the anatomical structure of the nerve fiber system from a series of diffusion-weighted images by the maximum intensity projection method. To examine the clinical usefulness of the proposed technique, many contiguous, thin (3 mm) coronal two-dimensional sections of the brain were acquired sequentially in normal volunteers and selected patients with paralyses, on a 1.5 Tesla MR system (Signa, GE) with an ECG-gated Stejskal-Tanner pulse sequence. The structure of the nerve fiber system of normal volunteers was almost the same as the anatomy. The tractograms of patients with paralyses clearly showed the degeneration of nerve fibers and were correlated with clinical symptoms. MR tractography showed great promise for the study of neuroanatomy and neuroradiology. (author)

2011-02-22

At the request of the Pacific Northwest National Laboratory, an in-depth analysis of the rapidly evolving state of real estate investments, high-performance building technology, and interest in efficiency was conducted by HaydenTanner, LLC, for the U.S. Department of Energy (DOE) Building Technologies Program. The analysis objectives were • to evaluate the link between high-performance buildings and their market value • to identify core messaging to motivate owners, investors, financiers, and others in the real estate sector to appropriately value and deploy high-performance strategies and technologies across new and existing buildings • to summarize financial mechanisms that facilitate increased investment in these buildings. To meet these objectives, work consisted of a literature review of relevant writings, examination of existing and emergent financial and policy mechanisms, interviews with industry stakeholders, and an evaluation of the value implications through financial modeling. This report documents the analysis methodology and findings, conclusion and recommendations. Its intent is to support and inform the DOE Building Technologies Program on policy and program planning for the financing of high-performance new buildings and building retrofit projects.

On the robust optimization to the uncertain vaccination strategy problem

International Nuclear Information System (INIS)

Chaerani, D.; Anggriani, N.; Firdaniza

2014-01-01

In order to prevent an epidemic of infectious diseases, the vaccination coverage needs to be minimized and also the basic reproduction number needs to be maintained below 1. This means that as we get the vaccination coverage as minimum as possible, thus we need to prevent the epidemic to a small number of people who already get infected. In this paper, we discuss the case of vaccination strategy in term of minimizing vaccination coverage, when the basic reproduction number is assumed as an uncertain parameter that lies between 0 and 1. We refer to the linear optimization model for vaccination strategy that propose by Becker and Starrzak (see [2]). Assuming that there is parameter uncertainty involved, we can see Tanner et al (see [9]) who propose the optimal solution of the problem using stochastic programming. In this paper we discuss an alternative way of optimizing the uncertain vaccination strategy using Robust Optimization (see [3]). In this approach we assume that the parameter uncertainty lies within an ellipsoidal uncertainty set such that we can claim that the obtained result will be achieved in a polynomial time algorithm (as it is guaranteed by the RO methodology). The robust counterpart model is presented

To assess hepatic steatosis by ultrasound method as a concomitant risk factor among overweight adolescents. A case-control study including 83 cases (47 overweight and 36 obese) and 89 controls (normal weight), frequency matched by gender, year of birth, pubertal stage (Tanner 4/5), and income. Cases and controls were selected from 1,420 students enrolled in a Vila Mariana public high school, in São Paulo, Brazil. Must et al. criteria were used for nutritional status classification. Nonalcoholic fatty liver disease was diagnosed through hepatic ultrasonography performed and analyzed by one radiologist. Hepatic enzymatic activities (alanine and aspartate transaminases, alkaline phosphatase, gamma-glutamyl transpeptidase) and direct bilirubin were measured. Eight covariables were fitted into logistic regression models; criterion for inclusion of variables was the association with overweight in the bivariate analyses (p 24 U/L were 10.77 (2.45-47.22) and 4.18 (1.46-11.94), respectively. This is the first population-based study showing that hepatic steatosis is strongly associated with overweight/obesity among adolescents attending a Brazilian public school. The diagnostic tool used in this investigation is a non-invasive method that might be applied to monitor overweight and obese adolescents and to propose actions for preventing more severe hepatic diseases in adulthood.

Two Ways to Examine Differential Constitutive Equations: Initiated on Steady or Initiated on Unsteady (LAOS Shear Characteristics

Directory of Open Access Journals (Sweden)

Jana Zelenkova

2017-06-01

Full Text Available The exponential Phan–Tien and Tanner (PTT, Giesekus, Leonov, and modified extended Pom–Pom (mXPP differential constitutive models are evaluated in two ways: with regard to steady shear characteristics and with regard to large amplitude oscillatory shear characteristics of a solution of poly(ethylene oxide in dimethyl sulfoxide. Efficiency of the models with nonlinear parameters optimized with respect to steady shear measurements is evaluated by their ability to describe large amplitude oscillatory shear (LAOS characteristics. The reciprocal problem is also analyzed: The nonlinear parameters are optimized with respect to the LAOS measurements, and the models are confronted with the steady shear characteristics. In this case, optimization is based on the LAOS measurements and equal emphasis is placed on both real and imaginary parts of the stress amplitude. The results show that the chosen models are not adequately able to fit the LAOS characteristics if the optimization of nonlinear parameters is based on steady shear measurements. It follows that the optimization of nonlinear parameters is much more responsible if it is carried out with respect to the LAOS data. In this case, when the optimized parameters are used for a description of steady shear characteristics, efficiency of the individual models as documented differs.

Pneumatology and discipleship: Trinity and church in the theology of Stanley Grenz

Full Text Available In today’s ecclesiology, the notion of the Spirit and the church has been heavily influenced by a recent and broad retrieval of Trinitarian theology. In this article, I discuss this in relationship to baptist and evangelical traditions as it is represented by Stanley Grenz. His “theology for the community of God” demonstrates the fruitfulness of the Trinitarian retrieval for such traditions. However, the main argument in the article is that it also implies certain risks. According to the Baptist tradition, the central message of the New Testament is the invitation to be a disciple of Jesus Christ. As Kathryn Tanner and Karen Kilby have argued elsewhere, when the biblical challenge to be like Jesus Christ is turned into a more general exhortation to become an image of the Trinity, it often results in abstract ethics and an ecclesiology that focuses mainly on general exhortations to love and to live in community. In contrast, this article claims that the biblical notion of discipleship has greater possibilities to allow for a more substantial and more holistic account of the Church, one that reunites ecclesiology, ethics and the Spirit’s transformative work within liturgy, charismatic service and mission.

In view of the problems that the encoding complexity of quasi-cyclic low-density parity-check (QC-LDPC) codes is high and the minimum distance is not large enough which leads to the degradation of the error-correction performance, the new irregular type-II QC-LDPC codes based on perfect cyclic difference sets (CDSs) are constructed. The parity check matrices of these type-II QC-LDPC codes consist of the zero matrices with weight of 0, the circulant permutation matrices (CPMs) with weight of 1 and the circulant matrices with weight of 2 (W2CMs). The introduction of W2CMs in parity check matrices makes it possible to achieve the larger minimum distance which can improve the error- correction performance of the codes. The Tanner graphs of these codes have no girth-4, thus they have the excellent decoding convergence characteristics. In addition, because the parity check matrices have the quasi-dual diagonal structure, the fast encoding algorithm can reduce the encoding complexity effectively. Simulation results show that the new type-II QC-LDPC codes can achieve a more excellent error-correction performance and have no error floor phenomenon over the additive white Gaussian noise (AWGN) channel with sum-product algorithm (SPA) iterative decoding.

Infertility can be the result of some common cancer treatments and can significantly impact quality of life. Semen cryopreservation allows for fertility preservation. We analyzed the semen parameters of specimens collected from pubertal males from the Children's Hospital of Philadelphia (CHOP) in order to expand current knowledge on the quality of these specimens and inform a standard clinical practice. Males who were at least Tanner stage III and newly diagnosed with cancer at CHOP were approached regarding sperm banking. The success and quality of the samples collected were analyzed and compared in relation to prior treatment, age, and diagnosis. From 399 patients approached for semen collection, 339 (85%) attempted to bank sperm, of which 265 (78%) were successful and 60 (15%) refused to participate. Therapy prior to sperm banking significantly impacted a successful collection (P semen. There was no difference in azoospermia across diagnostic groups (P = 0.35), though there were differences in quality of semen parameters across diagnoses. Our data support that sperm banking pubertal males prior to the initiation of therapy is feasible. While there were differences in quality of semen parameters across age and diagnostic groups, most males, regardless of age or diagnosis, had adequate specimens for cryopreservation. © 2016 Wiley Periodicals, Inc.

The great pipeline debate : the Minister of everything

International Nuclear Information System (INIS)

This article described the challenges facing Trans-Canada Pipelines (TCPL) in the 1950s regarding the construction of a pipeline to deliver gas to central Canadian markets. Alberta had been granted gas export permits, and the proposed pipeline was financed primarily by American interests. In addition, TCPL had difficulties with several competing proposals to move gas east from Alberta. There was also opposition to TCPL's original route which was through American territory. When the pipeline was rerouted through rugged Precambrian Shield, private-sector financiers balked at the additional costs. During the Great Pipeline debate in 1956, federal Minister C.D. Howe encouraged TCPL and its competitors to merge and put a bill before Parliament to create a Crown corporation to build and own the Canadian Shield portion of the line, leasing it back to TCPL. The first president of TCPL was Eldon Tanner, member of Alberta's Legislative Assembly. He remained at the helm until the pipeline was completed. Industrialist Frank McMahon who participated in drilling activities in British Columbia and at Turner Valley, Alberta, also promoted a plan to complete the construction of the Westcoast Transmission pipeline from the Peace River, Canada's first large natural-gas pipeline. 4 figs

This study evaluated the impact of professional training on serum oxidant and antioxidant status in adolescent endurance athletes and compared it with that of untrained individuals. Firstly, serum thiobarbituric-acid-reactive substances (TBARSs), xanthine oxidase (XO), catalase (CAT), reduced glutathione (GSH), superoxide dismutase (SOD), and total antioxidant capacity (T-AOC) were measured in 67 male runners, cyclists, and untrained adolescents. Seven-day dietary intakes were also assessed. Secondly, for age- and Tanner-stage-matched comparison, 36 out of the 67 subjects (12 for each group) were then selected and investigated. In cyclists, XO, GSH, and CAT were higher as compared with runners and controls. The CAT in runners, but not GSH and XO, was also higher than in controls. TBARS, T-AOC, and SOD did not differ among the study populations. Regarding the inter-individual relationships among serum redox statuses and dietary nutrient intakes, significant correlations were noted in CAT versus carbohydrates, protein, magnesium, and manganese; GSH versus carbohydrates, protein, fat, selenium, zinc, iron, and magnesium; XO versus cholesterol; CAT versus GSH. These findings suggest that the resting blood redox balance in the professional adolescent athletes was well maintained partly by the increase of individual antioxidant in adaptation to chronic exercise.

In Thailand, studies of growth date back to 1975, but there have been no studies examining any trends in increasing/decreasing growth. To determine if there have been any secular trends of increasing/decreasing growth and/or ages at puberty in Thai children. In 2012, a cross-sectional study of growth was conducted in 3460 children. The median heights and weights and the ages of pubertal maturation were compared with previous studies. Correlations between the secular trends and the health statistics indicators were calculated. From 1975-2012, the median final height of boys and girls had increased by 1.32 and 0.86 cm/decade and weight by 2.49 and 1.76 kg/decade, respectively. In girls, the age at thelarche and menarche had declined by 0.39 and 0.12 years/decade, respectively. In boys, the age at testicular enlargement Tanner II had declined by 0.15 years/decade. Increased physical growth was positively correlated to life expectancy, per capita income and prevalence of overweight/obesity was negatively correlated to prevalence of malnutrition and under-five mortality rate. The positive secular trend towards an increase in growth and a decline in the age at onset of puberty of Thai children is correlated with improvements in overall living conditions in Thailand.

To date, tanning prevention programs have led to limited success. The aim of the present study was to investigate potential unexpected prevention effects of completing an online survey focused on tanning attitudes, behaviors, and knowledge among female college tanners. A sample of 92 female undergraduate students from the USA, mean age = 20.09, SD = 1.41 years, who engaged in indoor tanning completed an online survey assessing awareness of tanning-related health risks, appearance-based motivations to tan and not to tan, media literacy related to tanning marketing, and tanning behaviors in 2013. Four months later, participants were invited to complete a follow-up survey assessing tanning intentions and behaviors since completing the initial survey. Fifty-one participants (55%) completed the follow-up questions, of whom 43 (84.3%) reported having decreased or ceased engaging in indoor tanning. In addition participants provided comments indicating that completing the survey had lead to decreases in their tanning behaviors. Our study presents novel and compelling support for using brief online surveys for decreasing health-risk behaviors such as sunbed use. Such measures are extremely cost-effective and easy to disseminate and implement. Replication and extension of these findings are warranted.

Relationships between skeletal maturation and fundamental motor skills and gross motor coordination were evaluated in 429 children (213 boys and 216 girls) 7-10 years. Skeletal age was assessed (Tanner-Whitehouse 2 method), and stature, body mass, motor coordination (Körperkoordinations Test für Kinder, KTK) and fundamental motor skills (Test of Gross Motor Development, TGMD-2) were measured. Relationships among chronological age, skeletal age (expressed as the standardised residual of skeletal age on chronological age) and body size and fundamental motor skills and motor coordination were analysed with hierarchical multiple regression. Standardised residual of skeletal age on chronological age interacting with stature and body mass explained a maximum of 7.0% of the variance in fundamental motor skills and motor coordination over that attributed to body size per se. Standardised residual of skeletal age on chronological age alone accounted for a maximum of 9.0% of variance in fundamental motor skills, and motor coordination over that attributed to body size per se and interactions between standardised residual of skeletal age on chronological age and body size. In conclusion, skeletal age alone or interacting with body size has a negligible influence on fundamental motor skills and motor coordination in children 7-10 years.

Trivalent chromium (Cr) is an environmental contaminant, which is extensively used in tanning industries throughout the world and causes various forms of health hazards in tannery workers. Therefore, a cross-sectional study design was used to evaluate the DNA damage and oxidative stress condition in tannery workers exposed to Cr in North India. The study population comprised 100 male tanners in the exposed group and 100 healthy males (no history of Cr exposure) in the comparable control group. Baseline characteristics including age, smoking, alcohol consumption habits and duration of exposure were recorded via interviewing the subjects. Blood Cr level (measured by atomic absorption spectrophotometry), DNA damage (measured by comet assay) and oxidative stress parameters (malondialdehyde (MDA), glutathione (GSH) and superoxide dismutase (SOD)) were estimated in both the groups. As a result of statistical analysis, exposed group showed significantly higher level of Cr (p  0.05) on DNA damage and oxidative stress parameters in both the groups. In simple and multiple correlation analysis, DNA damage and oxidative stress parameters showed significant correlation with Cr level and duration of exposure in exposed group. The findings of the present study revealed that chronic occupational exposure to trivalent Cr may cause DNA damage and oxidative stress in tannery workers. © The Author(s) 2012.

For age-, gender-, and Tanner-stage-matched comparison, 26 runners (n=13 in each group were selected and studied. Following the conditioning program, unaltered serum levels of thiobarbituric acid reactive substances (TBARS, total antioxidant capacity (T-AOC, and superoxide dismutase accompanied with an increase in oxidized glutathione (GSSG and decreases of xanthine oxidase, reduced glutathione (GSH, and GSH/GSSG ratio were observed in both Alt and SL groups. Serum glutathione peroxidase and catalase did not change in SL, whereas these enzymes, respectively, decreased and increased in Alt. Uric acid (UA decreased in SL and increased in Alt. Moreover, the decreases in GSH and GSH/GSSG ratio in Alt were relatively lower compared to those in SL. Further, significant interindividual correlations were found between changes in catalase and TBARS, as well as between UA and T-AOC. These findings suggest that long-term training at natural low altitude is unlikely to cause retained oxidative stress in professional adolescent runners.

Exploring rater agreement: configurations of agreement and disagreement

ALEXANDER VON EYE

Full Text Available At the level of manifest categorical variables, a large number of coefficients and models for the examination of rater agreement has been proposed and used for descriptive and explanatory purposes. This article focuses on exploring rater agreement. Configural Frequency Analysis (CFA is proposed as a method of exploration of cross-classifications of raters’ judgements. CFA allows researchers to (1 examine individual cells and sets of cells in agreement tables; (2 examine cells that indicate disagreement; and (3 explore agreement and disagreement among three or more raters. Four CFA base models are discussed. The first is the model of rater agreement that is also used for Cohen’s (1960  (kappa. This model proposes independence of raters’ judgements. Deviations from this model suggest agreement or disagreement beyond chance. The second CFA model is based on a log-linear null model. This model is also used for Brennan and Prediger’s (1981 n. It proposes a uniform distribution of ratings. The third model is that of Tanner and Young (1985. This model proposes equal weights for agreement cases and independence otherwise. The fourth model is the quasi-independence model. This model allows one to blank out agreement cells and thus to focus solely on patterns of disagreement. Examples use data from applicant selection.

Full Text Available In pediatrics, bone age also called skeletal maturity, an expression of biological maturity of a child, is an important quantitative measure for the clinical diagnosis of endocrinological problems and growth disorders. The present paper discusses a Java script implementation of Tanner-Whitehouse Method on computer, with complete graphical interface that include pictures and explanations for every bone. The program allows to select a stage (from a set of 7 or 8 stages for every bone (from a set of 20 bones, and also allow user to input some specific data such as natural age, sex, place of residence. Based on TW2 reported values, selected and input data, the program compute the bone age. Java script functions and objects were used in order to make an efficient and adaptive program. Note that in classic way, the program implementation it requires more than 160 groups of instructions only for user interface design. Using of dynamic creation of page, the program became smaller and efficient. The program was tested and put on a web server to serve for directly testing via http service and from where can also be download and runes from a personal computer without internet connection: http://vl.academicdirect.ro/medical_informatics/bone_age/v1.0/

In order to prevent an epidemic of infectious diseases, the vaccination coverage needs to be minimized and also the basic reproduction number needs to be maintained below 1. This means that as we get the vaccination coverage as minimum as possible, thus we need to prevent the epidemic to a small number of people who already get infected. In this paper, we discuss the case of vaccination strategy in term of minimizing vaccination coverage, when the basic reproduction number is assumed as an uncertain parameter that lies between 0 and 1. We refer to the linear optimization model for vaccination strategy that propose by Becker and Starrzak (see [2]). Assuming that there is parameter uncertainty involved, we can see Tanner et al (see [9]) who propose the optimal solution of the problem using stochastic programming. In this paper we discuss an alternative way of optimizing the uncertain vaccination strategy using Robust Optimization (see [3]). In this approach we assume that the parameter uncertainty lies within an ellipsoidal uncertainty set such that we can claim that the obtained result will be achieved in a polynomial time algorithm (as it is guaranteed by the RO methodology). The robust counterpart model is presented.

Full Text Available Abstract Background Non-invasive screening investigations are rarely used for assessing the activation and progression of the hypothalamic-pituitary gonadal axis through puberty. This study aimed to establish a normal range for urinary gonadotrophins in children progressing through puberty. Methods Urine samples were collected from 161 healthy school children (76 boys, 85 girls aged 4–19 yrs. Height and weight were converted to standard deviation score. Pubertal status, classified by Tanner staging, was determined by self-assessment. Urinary gonadotrophins were measured by chemiluminescent microparticle immunoassay. Results were grouped according to pubertal status (pre-pubertal or pubertal. Results Of the 161 children, 50 were pre-pubertal (28 boys; 22 girls and 111 were pubertal (48 boys; 63 girls. Overall, urinary gonadotrophins concentrations increased with pubertal maturation. All pre-pubertal children had a low urinary LH:Creatinine ratio. LH:Creatinine ratios were significantly higher in pubertal compared to pre-pubertal boys (pp = 0.006. However, LH:FSH ratios were a more consistent discriminant between pre-pubertal and pubertal states in both sexes (Boys 0.45 pubertal vs 0.1 pre-pubertal; girls 0.23 pubertal vs 0.06 pre-pubertal. Conclusion Urinary gonadotrophins analyses could be used as non-invasive integrated measurement of pubertal status which reflects clinical/physical status.

Parents of hospitalized children, especially parents of children with complex and chronic health conditions, report not being adequately prepared for self-management of their child's care at home after discharge. No theory-based discharge intervention exists to guide pediatric nurses' preparation of parents for discharge. To develop a theory-based conversation guide to optimize nurses' preparation of parents for discharge and self-management of their child at home following hospitalization. Two frameworks and one method influenced the development of the intervention: the Individual and Family Self-Management Theory, Tanner's Model of Clinical Judgment, and the Teach-Back method. A team of nurse scientists, nursing leaders, nurse administrators, and clinical nurses developed and field tested the electronic version of a nine-domain conversation guide for use in acute care pediatric hospitals. The theory-based intervention operationalized self-management concepts, added components of nursing clinical judgment, and integrated the Teach-Back method. Development of a theory-based intervention, the translation of theoretical knowledge to clinical innovation, is an important step toward testing the effectiveness of the theory in guiding clinical practice. Clinical nurses will establish the practice relevance through future use and refinement of the intervention. © 2017 Sigma Theta Tau International.

Cowan, David

2018-04-17

In 1948, worried that young people would take full employment and the welfare state for granted, the Labour Party trialled a new slogan: 'Ask your Dad'. This slogan encouraged the young to learn about the hardships which their parents had experienced in the inter-war years, largely under Conservative governments. Using archived interviews and letters sent to the press, this article provides the first study of the popular reception of this slogan. Most people had not heard of this slogan, and most of those who had heard of the phrase showed no knowledge that it was associated with politics, turning instead to popular culture. Those who understood the slogan were not the passive conduits of their party's message; often, they reworked political ideas to fit their own memories. Because repeating slogans was associated with a lack of political independence, not listening to party politics could conceal an intense interest in creating political change-an attitude which was, apparently, pronounced amongst the young. This article uses these responses to suggest how political language was as much produced by ordinary people's memories and daily discussion, as it was something drawn from professional campaigners.

Lower-limb growth: how predictable are predictions?

Science.gov (United States)

Kelly, Paula M; Diméglio, Alain

2008-12-01

The purpose of this review is to clarify the different methods of predictions for growth of the lower limb and to propose a simplified method to calculate the final limb deficit and the correct timing of epiphysiodesis. Lower-limb growth is characterized by four different periods: antenatal growth (exponential); birth to 5 years (rapid growth); 5 years to puberty (stable growth); and puberty, which is the final growth spurt characterized by a rapid acceleration phase lasting 1 year followed by a more gradual deceleration phase lasting 1.5 years. The younger the child, the less precise is the prediction. Repeating measurements can increase the accuracy of predictions and those calculated at the beginning of puberty are the most accurate. The challenge is to reduce the margin of uncertainty. Confrontation of the different parameters-bone age, Tanner signs, annual growth velocity of the standing height, sub-ischial length and sitting height-is the most accurate method. Charts and diagrams are only models and templates. There are many mathematical equations in the literature; we must be able to step back from these rigid calculations because they are a false guarantee. The dynamic of growth needs a flexible approach. There are, however, some rules of thumb that may be helpful for different clinical scenarios. For congenital malformations, at birth the limb length discrepancy must be multiplied by 5 to give the final limb length discrepancy. Multiple by 3 at 1 year of age; by 2 at 3 years in girls and 4 years in boys; by 1.5 at 7 years in girls and boys, by 1.2 at 9 years in girls and 11 years in boys and by 1.1 at the onset of puberty (11 years bone age for girls and 13 years bone age for boys). For the timing of epiphysiodesis, several simple principles must be observed to reduce the margin of error; strict and repeated measurements, rigorous analysis of the data obtained, perfect evaluation of bone age with elbow plus hand radiographs and confirmation with Tanner

Cluster Ions and Atmospheric Processes

Science.gov (United States)

D'Auria, R.; Turco, R. P.

We investigate the properties and possible roles of naturally occurring ions under at- mospheric conditions. Among other things, the formation of stable charged molecular clusters represents the initial stages of aerosol nucleation [e.g., Keesee and Castle- man, 1982], while the conversion of vapor to aggregates is the first step in certain atmospheric phase transitions [e.g. Hamill and Turco, 2000]. We analyze the stability and size distributions of common ionic clusters by solving the differential equations describing their growth and loss. The necessary reaction rate coefficients are deter- mined using kinetic and thermodynamic data. The latter are derived from direct labo- ratory measurements of equilibrium constants, from the classical charged liquid drop model applied to large aggregates (i.e., the Thomson model [Thomson, 1906]), and from quantum mechanical calculations of the thermodynamic potentials associated with the cluster structures. This approach allows us to characterize molecular clusters across the entire size range from true molecular species to larger aggregates exhibiting macroscopic behavior [D'Auria, 2001]. Cluster systems discussed in this talk include the proton hydrates (PHs) and nitrate-water and nitrate-nitric acid series [D'Auria and Turco, 2001]. These ions have frequently been detected in the stratosphere and tropo- sphere [e.g., Arnold et al., 1977; Viggiano and Arnold, 1981]. We show how the pro- posed hybrid cluster model can be extended to a wide range of ion systems, including non-proton hydrates (NPHs), mixed-ligand clusters such as nitrate-water-nitric acid and sulfate-sulfuric acid-water, as well as more exotic species containing ammonia, pyridine and other organic compounds found on ions [e.g., Eisele, 1988; Tanner and Eisele, 1991].

P. gingivalis is a black-pigmented gram-negative anaerobic rod and a secondary colonizer of dental plaque requiring antecedent organisms. The presence of this organism either alone or as a mixed infection with other bacteria and with the absence of beneficial species appears to be essential for disease activity. It is a predominant member of the subgingival microbiota in disease. It possesses and "excretes" numerous potentially toxic virulence factors. Aim of this study is to perform a systematic review of studies on P. gingivalis and its virulence factors with a special focus on its vaccine. Materials and Methods: An electronic and manual search based on agreed search phrases between the primary investigator and a secondary investigator was performed for the literature review till January 2014. The articles that were identified by this systematic review (total of 190 were analyzed in detail, which included the study of inference and conclusion. Conclusions: Within the limits of this systematic review, it can be concluded that P. gingivalis induce immune inflammatory response in periodontitis subjects. Therapeutic vaccines need to be developed and studied for their efficacy in controlling periodontitis.

A series of preliminary studies has been performed in the authors laboratories to explore the use of a priori information in Bayesian image restoration and reconstruction. One piece of a priori information is the fact that intensities of neighboring pixels tend to be similar if they belong to the same region within which similar tissue characteristics are exhibited. this property of local continuity can be modeled by the use of Gibbs priors, as first suggested by German and Geman. In their investigation, they also included line sites between each pair of neighboring pixels in the Gibbs prior and used discrete binary numbers to indicate the absence or presence of boundaries between regions. These two features of the a priori model permit averaging within boundaries of homogeneous regions to alleviate the degradation caused by Poisson noise. with the use of this Gibbs prior in combination with the technique of stochastic relaxation, German and Geman demonstrated that noise levels can be reduced significantly in 2-D image restoration. They have developed a Bayesian method that utilizes a Gibbs prior to describe the spatial correlation of neighboring regions and takes into account the effect of limited spatial resolution as well. The statistical framework of the proposed approach is based on the data augmentation scheme suggested by Tanner and Wong. Briefly outlined here, this Bayesian method is based on Geman and Geman's approach

Cardiopulmonary exercise testing is advised ahead of exercise intervention in obese adolescents to assess medical safety of exercise and physical fitness. Optimal validity and reliability of test results are required to identify maximal exercise effort. As fat oxidation during exercise is disturbed in obese individuals, it remains an unresolved methodological issue whether the respiratory gas exchange ratio (RER) is a valid marker for maximal effort during exercise testing in this population. RER during maximal exercise testing (RERpeak), and RER trajectories, was compared between obese and lean adolescents and relationships between RERpeak, RER slope and subject characteristics (age, gender, Body Mass Index [BMI], Tanner stage, physical activity level) were explored. Thirty-four obese (BMI: 35.1±5.1 kg/m²) and 18 lean (BMI: 18.8±1.9 kg/m²) adolescents (aged 12-18 years) performed a maximal cardiopulmonary exercise test on bike, with comparison of oxygen uptake (VO2), heart rate (HR), expiratory volume (VE), carbon dioxide output (VCO2), and cycling power output (W). RERpeak (1.09±0.06 vs. 1.14±0.06 in obese vs. lean adolescents, respectively) and RER slope (0.03±0.01 vs. 0.05±0.01 per 10% increase in VO2, in obese vs. lean adolescents, respectively) was significantly lower in obese adolescents, and independently related to BMI (Pexercise testing in this population.

The variation of skeletal maturity about chronological age is a sensitive indicator of population health. Age appropriate or advanced skeletal maturity is a reflection of adequate environmental and social conditions, whereas delayed maturation suggests inadequate conditions for optimal development. There remains a paucity of data, however, to indicate which specific biological and environmental factors are associated with advancement or delay in skeletal maturity. The present study utilises longitudinal data from the South African Birth to Twenty (Bt20) study to indentify predictors of relative skeletal maturity (RSM) in early adolescence. A total of 244 black South African children (n=131 male) were included in this analysis. Skeletal maturity at age 9/10 years was assessed using the Tanner and Whitehouse III RUS technique. Longitudinal data on growth, socio-economic position and pubertal development were entered into sex-specific multivariable general linear regression models with relative skeletal maturity (skeletal age-chronological age) as the outcome. At 9/10 years of age males showed an average of 0.66 years delay in skeletal maturation relative to chronological age. Females showed an average of 1.00 year delay relative to chronological age.

A male teenager formerly found to have a 46,XY,del(3)(p26)de novo karyotype was restudied. At the age of 14(8/12) yr, he attends the last grade of middle school and was a cooperating teenager with slender habitus, severe myopia, prominent nose, sacral dimples, pubertal stage Tanner III, and multiple surgical scars. Neuropsychological studies revealed a full scale IQ of 95 with slow performance (WISC-IV Spanish test) as well as an internalizing behavioral profile, poor social skills, a mild attention deficit, somatic complaints, and a feminized gender role. FISH with the 3p subtelomeric probe revealed that the deleted chromosome actually lacked the specific signal (n=10 cells). The patient's average intelligence confirms that euchromatic imbalances do not necessarily cause mental retardation and suggests that his deletion actually included the CALL gene, the Contactin 4 gene and other 3p26 genes related to intellectual capabilities; yet, the resulting hemizygosity either did not lead to haploinsufficiency or was minimally expressed. Moreover, the patient's peculiar cognitive and behavioral profile suggests that the 3p26 deletion is associated with a distinctive neuropsychological phenotype. Incidentally we comment on authorship and publication ethics in order to urge our institutional ethics committee to arbitrate authorship conflicts and thereby be consistent with its ethical commitment.

Production of waste hair in the leather manufacturing industry is increasing every year due to the adoption of hair-save unhairing techniques, leaving the tanners with the problem of coping with yet another solid by-product. Numerous potential strategies for hair utilisation have been proposed. However, the use of hair waste as agricultural fertiliser is one of its most promising applications due to the high nitrogen content of hair. Agricultural value of hair can be increased by composting. This paper deals with the composting of hair from the unhairing of bovine hide. Results indicated that hair cannot be either composted on its own or co-composted with de-inking sludge, a chemical complementary co-substrate. However, good results were obtained when co-composted with raw sludge from a municipal wastewater treatment plant at hair:raw sludge weight ratios 1:1, 1:2 and, 1:4 in lab scale and pilot plant scale composters. In all cases, a more stable product was achieved at the end of the process. Composting in the pilot plant composter was effectively monitored using Static Respiration Indices determined at process temperature at sampling (SRI(T)) and at 37 degrees C (SRI(37)). Notably, SRI(T) values were more sensitive to changes in the biological activity. In contrast, Respiratory Quotient (RQ) values were not adequate to follow the development of the process.

Full Text Available Mette Mogensen1, Gregor BE Jemec21Department of Dermatology, Gentofte Hospital, Hellerup, Denmark; 2Department of Dermatology, Roskilde Hospital, Health Sciences Faculty, University of Copenhagen, Roskilde, DenmarkIntroduction: In 2009, the WHO listed ultraviolet (UV radiation as a group 1 carcinogen. In spite of this, each year, millions of people tan indoor in Western countries. The aim of this review is to summarize evidence of tanning bed carcinogenesis and to present guidelines for use of tanning beds and patient safety advice.Methods: A narrative review of the literature was conducted based on both PubMed and Medline searches and on literature review of the retrieved papers.Results: Use of indoor tanning beds represents a significant and avoidable risk factor for the development of both melanoma and nonmelanoma skin cancers. Frequent tanners are more often adolescent females. Tanning beds have additional potential adverse effects such as burns, solar skin damage, infection, and possibly also addictive behavior.Discussion: The effort in preventing UV light-induced carcinogenesis should currently be aimed at developing new strategies for public health information. Tanning beds are one preventable source of UV radiation. In the majority of people solar UV radiation continues to be the major factor and therefore anti-tanning campaigns must always include sunbathers.Keywords: tanning beds, skin cancers, melanoma, nonmelanoma

Numerical modeling of bubble dynamics in viscoelastic media with relaxation

Cavitation occurs in a variety of non-Newtonian fluids and viscoelastic materials. The large-amplitude volumetric oscillations of cavitation bubbles give rise to high temperatures and pressures at collapse, as well as induce large and rapid deformation of the surroundings. In this work, we develop a comprehensive numerical framework for spherical bubble dynamics in isotropic media obeying a wide range of viscoelastic constitutive relationships. Our numerical approach solves the compressible Keller-Miksis equation with full thermal effects (inside and outside the bubble) when coupled to a highly generalized constitutive relationship (which allows Newtonian, Kelvin-Voigt, Zener, linear Maxwell, upper-convected Maxwell, Jeffreys, Oldroyd-B, Giesekus, and Phan-Thien-Tanner models). For the latter two models, partial differential equations (PDEs) must be solved in the surrounding medium; for the remaining models, we show that the PDEs can be reduced to ordinary differential equations. To solve the general constitutive PDEs, we present a Chebyshev spectral collocation method, which is robust even for violent collapse. Combining this numerical approach with theoretical analysis, we simulate bubble dynamics in various viscoelastic media to determine the impact of relaxation time, a constitutive parameter, on the associated physics. Relaxation time is found to increase bubble growth and permit rebounds driven purely by residual stresses in the surroundings. Different regimes of oscillations occur depending on the relaxation time.

The Use of High-Density SNP Array to Map Homozygosity in Consanguineous Families to Efficiently Identify Candidate Genes: Application to Woodhouse-Sakati Syndrome

Full Text Available Two consanguineous Qatari siblings presented for evaluation: a 17-4/12-year-old male with hypogonadotropic hypogonadism, alopecia, intellectual disability, and microcephaly and his 19-year-old sister with primary amenorrhea, alopecia, and normal cognition. Both required hormone treatment to produce secondary sex characteristics and pubertal development beyond Tanner 1. SNP array analysis of both probands was performed to detect shared regions of homozygosity which may harbor homozygous mutations in a gene causing their common features of abnormal pubertal development, alopecia, and variable cognitive delay. Our patients shared multiple homozygous genomic regions; ten shared regions were >1 Mb in length and constituted 0.99% of the genome. DCAF17, encoding a transmembrane nuclear protein of uncertain function, was the only gene identified in a homozygous region known to cause hypogonadotropic hypogonadism. DCAF17 mutations are associated with Woodhouse-Sakati syndrome, a rare disorder characterized by alopecia, hypogonadotropic hypogonadism, sensorineural hearing loss, diabetes mellitus, and extrapyramidal movements. Sequencing of the coding exons and flanking intronic regions of DCAF17 in the proband revealed homozygosity for a previously described founder mutation (c.436delC. Targeted DCAF17 sequencing of his affected sibling revealed the same homozygous mutation. This family illustrates the utility of SNP array testing in consanguineous families to efficiently and inexpensively identify regions of genomic homozygosity in which genetic candidates for recessive conditions can be identified.

Heterosexual Men's Ratings of Sexual Attractiveness of Adolescent Girls: A Cross-Cultural Analysis.

Following an identical procedure to the one we previously reported (O'Donnell, Lowe, Brotherton, & Bennett, 2014), we examined ratings of sexual attraction to photographs of (the same) adolescent girls (Tanner stages 3-4) labelled as either 14-15 years or 16-17 years old, women, and men. Ratings were made by Bulgarian heterosexual men by pressing buttons on a response box which recorded the ratings made and the time in milliseconds taken to respond. Despite the age of sexual consent in Bulgaria being 14 years, the pattern of findings did not differ from those found in the UK, where the age of consent is 16 years. That is, mean ratings of the sexual attractiveness of the girls labelled as younger were lower than those of the (same) girls labelled as older, and those of the women. In addition, correlations revealed significantly longer responding times when younger girls (and men) were rated as more highly sexually attractive. These associations were reversed in response to the photographs of women. We take these findings to indicate an inhibitory effect arising from generalized sexual norms relating to the inappropriateness of sexual attraction to young girls; the greater the attraction, the higher the inhibition. This second replication of our initial findings suggests a robust effect that may be of benefit in exploration of pedophile or sex offender groups.

46,XY pure gonadal dysgenesis (Swyer syndrome) is characterized by normal female genitalia at birth. It usually first becomes apparent in adolescence with delayed puberty and amenorrhea. Rarely, patients can present with spontaneous breast development and/or menstruation. A fifteen-year-old girl presented to our clinic with the complaint of primary amenorrhea. On physical examination, her external genitals were completely female. Breast development and pubic hair were compatible with Tanner stage V. Hormonal evaluation revealed a hypergonadotropic state despite a normal estrogen level. Chromosome analysis revealed a 46,XY karyotype. Pelvic ultrasonography showed small gonads and a normal sized uterus for age. SRY gene expression was confirmed by multiplex polymerase chain reaction. Direct sequencing on genomic DNA did not reveal a mutation in the SRY, SF1 and WT1 genes. After the diagnosis of Swyer syndrome was made, the patient started to have spontaneous menstrual cycles and therefore failed to attend her follow-up visits. After nine months, the patient underwent diagnostic laparoscopy. Frozen examination of multiple biopsies from gonad tissues revealed gonadoblastoma. With this report, we emphasize the importance of performing karyotype analysis, which is diagnostic for Swyer syndrome, in all cases with primary or secondary amenorrhea even in the presence of normal breast development. We also suggest that normal pubertal development in patients with Swyer syndrome may be associated with the presence of a hormonally active tumor.

To identify growth, maturation and biomechanical risk factors for overuse injury in elite adolescent ballet dancers. Maturation (Tanner scale), growth (foot length change) and age at onset of menarche were recorded in elite adolescent ballet dancers. A modified knee valgus angle and lateral tilt of the pelvis were measured using 2D video during two dance movements (fondu, temps levé) to quantify lower extremity alignment. Overuse dance injuries were recorded by a physiotherapist. The injury rate ratio (RR) associated with each variable was estimated using over-dispersed Poisson regression modelling. Changes in right foot length (RR = 1.41, CI = 0.93-2.13), right knee angles during the fondu (RR = 0.68, CI = 0.45-1.03) and temps levé (RR = 0.72, CI = 0.53-0.98), and pelvic angles during the temps levé on the left (RR = 0.52, CI = 0.30-0.90) and fondu on the right (RR = 1.28, CI = 0.91-1.80) were associated with substantial changes in injury risk. Rate of growth in elite adolescent ballet dancers is likely associated with an increase in risk of lower extremity overuse injury and better right lower extremity alignment is likely associated with a reduction in risk of right lower extremity overuse injury.

Full Text Available Cushing’s disease (CD is the most common cause of endogenous Cushing’s syndrome in children and adolescents and represents a rare cause of short stature. A 14-year-old boy came to our attention for progressive weight gain and short stature. At examination, height was 140 cm (3rd centile and weight was 37.7 kg (10th centile. Tanner stage was G2, PH 3, testis 3 mL. Hypothyroidism and growth hormone deficiency were excluded. A marked increase of urinary free cortisol, a nonsuppressible serum cortisol after Liddle 1 test, and an elevated ACTH value confirmed the diagnosis of ACTH dependent Cushing’s syndrome. Pituitary magnetic resonance imaging (MRI showed a left microadenoma and a right focal area of lesser enhancement. Therefore, bilateral inferior petrosal sinus sampling (BIPSS with CRH stimulation was performed to obtain an accurate preoperative localization of the adenoma: the interpetrosal sinus ACTH gradient indicated lateralization of ACTH secretion to the left side. The patient underwent transsphenoidal surgery with selective microadenomectomy, with an immediate ACTH decline in the postoperative phase. Histology confirmed the diagnosis of corticotrophic pituitary adenoma. Glucocorticoid replacement therapy was instituted. Clinical examination demonstrated a rapid catch-up growth (10th centile, with a normalization of body mass index and an adequate pubertal development.

High spatial resolution observations in the 1 to 3.5 μm/ region of the Galactic Center source known historically as IRS 13 are presented. They include ground-based adaptive optics images in the H, Kp (2.12/0.4 μm) and L bands, HST-NICMOS data in filters between 1.1 and 2.2 μm, and integral field spectroscopic data from BEAR, an Imaging FTS, in the He I 2.06 μm/ and the Brγ line regions. Analysis of all these data provides a completely new picture of the main component, IRS 13E, which appears as a cluster of seven individual stars within a projected diameter of ˜0.5 arcsec (0.02 pc). The brightest sources, 13E1, 13E2, 13E3 which is detected as a binary, and 13E4, are all massive stars of different type. The star 13E1 is a luminous, blue object, with no detected emission line. 13E2 and 13E4 are two hot, high-mass emission line stars, 13E2 being at the WR stage and 13E4 a massive O-type star. In contrast, 13E3A and B are extremely red objects, proposed as other examples of dusty WR stars, like IRS 21 (Tanner et al. \\cite{tanner}). All these sources have a common westward proper motion (Ott et al. \\cite{ott2}) indicating they are bounded. Two other sources, detected after deconvolution of the AO images in the H and Kp bands, are also identified. One, that we call 13E5, is a red source similar to 13E3A and B, while the other one, 13E6, is probably a main sequence O star in front of the cluster. Considering this exceptional concentration of comoving massive hot stars, IRS 13E is proposed as the remaining core of a massive star cluster, which could harbor an intermediate-mass black hole (IMBH) (Portegies Zwart & McMillan \\cite{zwart2)} of ˜1300 M⊙. This detection plays in favor of a scenario, first suggested by Gerhard (\\cite{gerhard}), in which the helium stars and the other hot stars in the central parsec originate from the stripping of a massive cluster formed several tens of pc from the center. This cluster would have spiraled towards SgrA*, and IRS 13E

The age of cutting had an effect on the composition of the studied grasses. In most of the grasses, total carbohydrate levels, non-fibrous carbohydrates and A+B1 fraction carbohydrates increased linearly according to the age of cutting. The potentially degradable fraction of carbohydrates (fraction B2 showed a quadratic behavior according to the cutting ages for all grasses. The C fraction of the carbohydrates in tifton-85 grass linearly increased with the age but it did not increase significantly for the other grasses. In setaria grass, the intermediate levels of B2 and B3 nitrogenous fractions were high, which might represent a potential source of protein for ruminal degradation and for the small intestine. Except for setaria grass, all studied grasses show similar values of the A, B1, B2 and B3 nitrogenous fractions.Avaliaram-se pelo Sistema Cornell as frações de carboidratos e os compostos nitrogenados dos capins acroceres (Acroceras macrum, angola, (Brachiaria purpurascens, canarana (Echinochloa polystachya, hemarthria (Hemarthria altíssima, setária (Setaria anceps, tanner grass (Brachiaria arrecta e tifton 85 (Cynodon spp nas idades de corte de 14, 28, 42 e 56 dias.

Full Text Available BACKGROUND: Gastric volvulus is frequently an asymptomatic disease, and it is usually diagnosed during radiographic examination of the superior digestive tract. The acute form, however, can spawn serious and lethal clinical consequences. This disease is defined by the anomalous rotation of the stomach over itself, and it can be classified according to type, extension, direction, etiology, and clinical presentation. AIM: To review the records from 38 patients with gastric volvulus diagnosed in the Hospital das Clínicas of University of São Paulo between 1968 and 2001. METHODS: This is retrospective analysis of 38 patient records. It was collected from each patient: name, age of first symptom appearance, gender, main clinical findings and complementary exams, volvulus type, extension, direction, etiology, and clinical presentation, therapeutic procedures, type of surgery performed, eventual recurrence, and long-term evolution. RESULTS: It was observed that occurrences of gastric volvulus are mainly secondary (75.8%. For the majority of patients (n=33, surgery was chosen as the treatment option: chronic disease in 29 cases and acute in four. Conservative treatment was reserved only for patients with no clinical conditions to surgical treatment. Anterior gastropexy was associated to high recurrence rates. Suturing the low gastric curve to the hepatic capsule and the transverse colon to the left subphrenic space (Tanner´s operation seemed to be the technical treatment of choice for primary gastric volvulus. CONCLUSION: Treatment of gastric volvolus must be tailored according the etiology of the disease.RACIONAL: O volvo gástrico é frequentemente condição assintomática e diagnosticado em exame radiológico feito por outras causas.

How does the formation of the blood-testis barrier (BTB), as reflected by the expression of connexin 43 and claudin 11 proteins during the pubertal transition period, take place in vitro compared to samples from a large cohort of pre/peripubertal boys? The BTB connexin 43 and claudin 11 expression patterns appeared to be partially achieved in organotypic culture when compared to that in samples from 71 pre/peripubertal patients. Although alterations in the protein expression patterns of the BTB, whose main components are connexin 43 and claudin 11, are known to be associated with impaired spermatogenesis in mice and adult men, there is a lack of knowledge on its formation in pre-peripubertal human tissue both in vitro and in vivo. Moreover, despite Sertoli cell (SC) maturation during long-term organotypic culture of immature testicular tissue (ITT), initiation of spermatogenesis has not yet been achieved. Histological sections from 71 pre-peripubertal patients were evaluated for the formation of the BTB acting as in-vivo controls according to age, SC maturation, clinical signs of puberty and germ cell differentiation. Testicular tissue fragments retrieved from three prepubertal boys were cultured in a long term organotypic system to analyze the BTB formation and expression pattern in correlation with SC maturation. Testicular histological sections from 71 patients aged 0-16 years who underwent a biopsy between 2005 and 2014 to preserve their fertility before gonadotoxic treatment were examined. Immunohistochemistry (IHC) results for connexin 43 and claudin 11 as BTB markers, using a semi-quantitative score for their expression, and for Anti-Mullerian hormone (AMH), as SC maturation marker, were analyzed. Germ cell differentiation was evaluated on Hematoxylin-Eosin sections. Tanner stages at the time of biopsy were recorded from medical files.

Previous investigations have explored stress and pubertal hormones in parallel; it has been a recent development, however, to explore the relationships between different hormones during puberty, and how this hormonal cross-talk may be influenced by the environment. The current study investigated neuroendocrine coupling, or the extent to which hormones are correlated within the individual, and also investigated early life stressors that may influence coupling. Participants were 405 adrenarcheal children (mean Tanner stage=1.73 for girls and 1.38 for boys) from a longitudinal study who provided saliva samples for analysis of cortisol, dehydroepiandrosterone (DHEA), and testosterone. Saliva was collected when children were 9-years-old, while early life stressors were assessed at each longitudinal assessment (ages 3, 6, and 9). Results from multi-level modeling (MLM) analyses provided evidence of positive cortisol-dehydroepiandrosterone (DHEA) and cortisol-testosterone coupling in middle childhood, and identified body mass index as a predictor of the strength of hormone coordination. While exposure to stressful life events did not impact cortisol-DHEA coupling patterns, stress interacted with sex to predict looser cortisol-testosterone coupling in girls, but not boys. The current study adds to the existing literature on the development of neuroendocrine coupling, and provided further evidence of sex differences in the impact of stress. Furthermore, hormone coupling may be investigated in the future as a mechanism by which puberty is associated with negative behavioral outcomes. Copyright © 2017 Elsevier B.V. All rights reserved.

X-Chromosome Effects on Attention Networks: Insights from Imaging Resting-State Networks in Turner Syndrome.

Attention deficit hyperactivity disorder (ADHD) is strongly affected by sex, but sex chromosomes' effect on brain attention networks and cognition are difficult to examine in humans. This is due to significant etiologic heterogeneity among diagnosed individuals. In contrast, individuals with Turner syndrome (TS), who have substantially increased risk for ADHD symptoms, share a common genetic risk factor related to the absence of the X-chromosome, thus serving as a more homogeneous genetic model. Resting-state functional MRI was employed to examine differences in attention networks between girls with TS (n = 40) and age- sex- and Tanner-matched controls (n = 33). We compared groups on resting-state functional connectivity measures from data-driven independent components analysis (ICA) and hypothesis-based seed analysis. Using ICA, reduced connectivity was observed in both frontoparietal and dorsal attention networks. Similarly, using seeds in the bilateral intraparietal sulcus (IPS), reduced connectivity was observed between IPS and frontal and cerebellar regions. Finally, we observed a brain-behavior correlation between IPS-cerebellar connectivity and cognitive attention measures. These findings indicate that X-monosomy contributes affects to attention networks and cognitive dysfunction that might increase risk for ADHD. Our findings not only have clinical relevance for girls with TS, but might also serve as a biological marker in future research examining the effects of the intervention that targets attention skills. © The Author 2017.

Full Text Available Introduction: Muslims fast from dawn to dusk during Ramadan. The effects of prolonged food deprivation on endocrine hormones have been studied in healthy adults but no previous study has investigated this effect on children. This study aimed to evaluate the feasible changes in serum level of thyroxin (T3, tetraiodothyronin (T4, thyroid stimulating hormone (TSH and body composition in pre-menarche girls. Methods: This cohort study was performed through Ramadan 2012. We enrolled fifty-eight 9-13years old girls (weight 34.20±7.96 kg, height 142.01±7.76 cm in two groups from (31  and 27 in fasted and non-fasted groups, respectively prior to Ramadan until afterwards. Weight and height of the subjects were measured using standard methods, and then Body Mass Index (BMI was calculated.  Body composition was measured using Bio Impedance Analyzer (BIA method.  Serum concentrations of T3, T4 and TSH hormones were measured by Radio Immunoassay (RIA. Paired t-test was used to compare result of each group before and after Ramadan. Independent t-test was used to compare two groups together. Tanner intervention variable was controlled by generalized linear models intervening test. SPSS.11 software was used for data analysis. Results: Ramadan fasting induces a significant decrease in BMI and weight on fasted group (p=0.005, p=0.044, respectively while a significant increase was observed in non-fasted group (p

We describe current pubertal development in healthy urban Chinese boys. A cross-sectional study of the pubertal development of 18,807 urban Chinese boys aged from 3.50 to 18.49years was conducted between 2003 and 2005. Testicular volume was evaluated with a Prader orchidometer. Pubic hair development was assessed according to the Tanner method. Data on spermarche were collected using the status quo method. Probit analysis was used to calculate the median age and 95% CI at different stages of testicular development, pubic hair development and spermarche. By age 9, 12.99% of the boys had a testicular volume of 4mL or greater. The median age of onset of puberty defined as the age at attainment of testicular volume of 4mL or greater was 10.55 (95% CI 10.27-10.79) years. The median age for onset of pubic hair development (PH(2) ) and spermarche was 12.78 (95%CI 12.67-12.89) years and 14.05 (95%CI 13.80-14.32) years, respectively. Pubertal onset in urban Chinese boys is earlier than currently used clinical norms but their pubic hair development occurs relatively late in comparison with the reported data from numerous other countries. There is also evidence of a secular trend towards an earlier age of spermarche since 1979 in Chinese urban boys. © 2011 The Authors.

To determine factors associated with pubertal gynecomastia. A cross-sectional study among healthy male school children and adolescents in Riyadh, Saudi Arabia. Subjects were selected from diverse socioeconomic backgrounds. Tanner stage, height, weight, blood hormonal levels (leutilizing hormone [LH], follicle-stimulating hormone [FSH], total testosterone, and estradiol), and anthropometric and lipid parameters (body mass index [BMI], triglycerides, high-density lipoprotein [HDL], and low-density lipoprotein [LDL]), were collected and compared in children with and without gynecomastia. The study included 542 children and adolescents. Median (interquartile range) age in the whole group was 11(8-13) years. The prevalence of gynecomastia was 185/542 (34%), with a peak at age 14. The 2 groups compared had nonsignificant difference in cholesterol (P=.331), LH (P=.215) and FSH (P=.571) levels. Those with gynecomastia were significantly older, had lower gonad stage, had higher anthropometric (height, weight, and BMI), and lipid (triglycerides, HDL, and LDL) values. In multivariate regression analysis, factors significantly associated with gynecomastia were BMI (odds ratio [OR]=1.05; 95%CI 1.00-1.10; P=.013), HDL (OR=0.42; 95%CI 0.19-0.92; P=.03), and gonad (Stage II OR=2.23; 95%CI 1.27-3.92; P=.005, Stage III OR=6.40; 95%CI 2.70-15.0; P gynecomastia tends to increase in mid-puberty. In our setting, BMI, HDL, and gonad stage were the major factors associated with the development of pubertal gynecomastia.

The assessment of the bone age, or skeletal maturity, is an important task in pediatrics that measures the degree of maturation of children's bones. Nowadays, there is no standard clinical procedure for assessing bone age and the most widely used approaches are the Greulich and Pyle and the Tanner and Whitehouse methods. Computer methods have been proposed to automatize the process; however, there is a lack of exploration about how to combine the features of the different parts of the hand, and how to take advantage of ensemble techniques for this purpose. This paper presents a study where the use of ensemble techniques for improving bone age assessment is evaluated. A new computer method was developed that extracts descriptors for each joint of each finger, which are then combined using different ensemble schemes for obtaining a final bone age value. Three popular ensemble schemes are explored in this study: bagging, stacking and voting. Best results were achieved by bagging with a rule-based regression (M5P), scoring a mean absolute error of 10.16 months. Results show that ensemble techniques improve the prediction performance of most of the evaluated regression algorithms, always achieving best or comparable to best results. Therefore, the success of the ensemble methods allow us to conclude that their use may improve computer-based bone age assessment, offering a scalable option for utilizing multiple regions of interest and combining their output.

NEW ECO-EFFICIENT PRODUCTS USED IN LEATHER INDUSTRY

2016-05-01

Full Text Available In today's move to "sustainable production" the leather industry, as well as many other industries is recognized as a polluting one. Traditional chemical operations are polluting because of the levels of inorganic chemical waste. Process chemicals which are not consumed within the reactions necessary to convert collagen to leather are currently discharged to waste. These are usually applied during bulk production, such as inorganic agents from beam house and tanning processes, e.g. lime, sulphide, ammonium salts, sulphuric acid and sodium chloride, mineral tanning agents – mainly Cr(III and the less common Al(III, Zr(III, Ti(III, Fe(III salts -, whereas depending on the tanning process and the leather article produced organic chemical waste discharged comprises aldehydic and polyphenolic tanning products, bating enzymes, organic carboxylic acids and excess electrolyte stable synthetic fat liquors. It is rare for chemicals and water to be recovered for re-use from several of these process steps. Moreover, tanners worldwide are required to operate within strict legislative boundaries. Serious drawbacks continuously arise concerning the chrome–tanning process in leather industry and the environmental hazardous consequences of chromium containing effluents. In order to overcome this impediment, a great deal of research has been focused on developing chrome–free tanning methods in the past years, such as titanium tanning. In the present study, Ti–Al tanned bovine leather was characterized by means of SEM microscopy, EDAX elemental analysis, ATR–FTIR spectroscopy, thermogravimetry TGA, and differential scanning calorimetry DSC techniques.

Background Indoor tanning increases skin cancer risk. Beyond early research describing melanoma and sun lamps, few recent reports describe where individuals indoor tan and whether skin cancer risk varies by location (business, home-based). Objective Assess where individuals tanned indoors and skin cancer risk by tanning device location. Methods Multivariate logistic regression in two US case-control studies of melanoma (1,161 cases, 1,083 controls, ages 25–59) and early-onset basal cell carcinoma (BCC) (375 cases, 382 controls, under age 40) conducted between 2004 and 2010. Results Most indoor tanners (86.4–95.1%), especially younger individuals, tanned exclusively in businesses. Persons who used indoor tanning exclusively in businesses were at increased risk of melanoma (OR=1.82, 95% CI=1.47–2.26) and BCC (OR=1.69, 95% CI=1.15–2.48) compared to non-users. Melanoma risk was also increased in the small number who reported tanning indoors only at home relative to non-users (OR=4.14, 95% CI=1.75–9.78); 67.6% used sun lamps. Limitations Self-reported tanning, potential recall bias. Conclusion Business only tanning, despite claims of “safe" tanning, was positively associated with a significant risk of melanoma and BCC. Home tanning was uncommon and mostly from sun lamps which were rarely used by younger participants. Regardless of location, indoor tanning was associated with increased risk of skin cancer.

Indoor tanning is a risk factor for melanoma among young white women. Health communications can be an effective way of reaching this population and promoting behavior change. The purpose of this study was (i) to investigate the associations between intention to quit indoor tanning and attitudes, normative pressure, and efficacy about quitting, and (ii) to identify beliefs about quitting indoor tanning that can be used to design effective health communication messages to reduce skin cancer risk. A national online survey was conducted with 279 non-Hispanic white women ages 18-25 in the USA who are indoor tanners. The survey, based on the reasoned action approach, assessed intention, attitudes, norms, and efficacy and their corresponding underlying beliefs related to quitting indoor tanning, along with other known covariates. Data were collected in November/December 2015. Intention to quit indoor tanning was significantly associated with attitudes, specifically with the beliefs that it would "reduce damage to skin" (increased intention) and "make me less happy" (decreased intention). While self-efficacy was not related to intention to quit indoor tanning, injunctive normative beliefs were with key referent groups including mothers, friends, and romantic partners. Messages aimed at discouraging indoor tanning among young, non-Hispanic, white women should highlight the salient belief that quitting indoor tanning will reduce skin damage, counter the belief that it will make them less happy, and highlight key people who would approve of them quitting indoor tanning.

Spatial Mapping of Translational Diffusion Coefficients Using Diffusion Tensor Imaging: A Mathematical Description.

In this article, we discuss the theoretical background for diffusion weighted imaging and diffusion tensor imaging. Molecular diffusion is a random process involving thermal Brownian motion. In biological tissues, the underlying microstructures restrict the diffusion of water molecules, making diffusion directionally dependent. Water diffusion in tissue is mathematically characterized by the diffusion tensor, the elements of which contain information about the magnitude and direction of diffusion and is a function of the coordinate system. Thus, it is possible to generate contrast in tissue based primarily on diffusion effects. Expressing diffusion in terms of the measured diffusion coefficient (eigenvalue) in any one direction can lead to errors. Nowhere is this more evident than in white matter, due to the preferential orientation of myelin fibers. The directional dependency is removed by diagonalization of the diffusion tensor, which then yields a set of three eigenvalues and eigenvectors, representing the magnitude and direction of the three orthogonal axes of the diffusion ellipsoid, respectively. For example, the eigenvalue corresponding to the eigenvector along the long axis of the fiber corresponds qualitatively to diffusion with least restriction. Determination of the principal values of the diffusion tensor and various anisotropic indices provides structural information. We review the use of diffusion measurements using the modified Stejskal-Tanner diffusion equation. The anisotropy is analyzed by decomposing the diffusion tensor based on symmetrical properties describing the geometry of diffusion tensor. We further describe diffusion tensor properties in visualizing fiber tract organization of the human brain.

The significant increase of skin cancer occurring in the western world is attributed to longer sun expose during leisure time. For prevention, people should become aware of the risks of UV light exposure by showing skin damage and the protective effect of sunscreen with an UV camera. An UV awareness imaging system optimized for 365 nm (UV-A) was develop using consumer components being interactive, safe and mobile. A Sony NEX5t camera was adapted to full spectral range. In addition, UV transparent lenses and filters were selected based on spectral characteristics measured (Schott S8612 and Hoya U-340 filters) to obtain the highest contrast for e.g. melanin spots and wrinkles on the skin. For uniform UV illumination, 2 facial tanner units were adapted with UV 365 nm black light fluorescent tubes. Safety of the UV illumination was determined relative to the sun and with absolute irradiance measurements at the working distance. A maximum exposure time over 15 minutes was calculate according the international safety standards. The UV camera was successfully demonstrated during the Dutch National Skin Cancer day and was well received by dermatologists and participating public. Especially, the 'black paint' effect putting sun screen on the face was dramatic and contributed to the awareness of regions on the face what are likely to be missed applying sunscreen. The UV imaging system shows to be promising for diagnostics and clinical studies in dermatology and potentially in other areas (dentistry and ophthalmology)

In order to meet the needs of high-speed development of optical communication system, a construction method of quasi-cyclic low-density parity-check (QC-LDPC) codes based on multiplicative group of finite field is proposed. The Tanner graph of parity check matrix of the code constructed by this method has no cycle of length 4, and it can make sure that the obtained code can get a good distance property. Simulation results show that when the bit error rate ( BER) is 10-6, in the same simulation environment, the net coding gain ( NCG) of the proposed QC-LDPC(3 780, 3 540) code with the code rate of 93.7% in this paper is improved by 2.18 dB and 1.6 dB respectively compared with those of the RS(255, 239) code in ITU-T G.975 and the LDPC(3 2640, 3 0592) code in ITU-T G.975.1. In addition, the NCG of the proposed QC-LDPC(3 780, 3 540) code is respectively 0.2 dB and 0.4 dB higher compared with those of the SG-QC-LDPC(3 780, 3 540) code based on the two different subgroups in finite field and the AS-QC-LDPC(3 780, 3 540) code based on the two arbitrary sets of a finite field. Thus, the proposed QC-LDPC(3 780, 3 540) code in this paper can be well applied in optical communication systems.

Among opinions issued by the Forensic Medicine Department, Medical Science University in Poznan, in the last six years, there are opinions concerning age estimation in child pornography materials. The issue subject to research is indicating persons under the age of 15 years in pornographic materials, since possession of pornographic materials featuring underage persons is considered a crime and is subject to article 202 of the Penal Code. The estimation of the age of teenagers based on secondary and tertiary sexual characteristics is increasingly more difficult and the available data in professional literature regarding the standard time of development differ among various authors of such studies. In the report, an attempt has been made at determining the agreement regarding different characteristics in the data included in the Tanner's scale, which has been modified to accommodate the research done on persons registered by electronic means. The modified scale, which up to now has been used in research of registered subjects in classified public prosecutors' materials, has been employed in children seen in a pediatric outpatient department. The goal has been a comparison of the outcome of the research to prove its usefulness so that in the future, the modified scale could be used as a research tool in estimation of age of persons appearing in pornography materials. medical forms of 205 children seen in a pediatric outpatient department, based on the scale created by the present authors us and later processed using Excel.

Thalassaemic patients are in need of frequent assessment of bone age because of growth failure and pubertal disorders. To compare the ''rapid'' Greulich and Pyle (G and P) method with the third edition of the Tanner and Whitehouse (TW3) method for determining skeletal maturity and predicting final height in thalassaemic patients. A total of 191 radiographs from 58 patients (28 male, 30 female) were retrospectively evaluated by two investigators, one for each method. In 47 radiographs from 15 patients having attained their adult height, predicted final height was calculated according to each method. The mean bone ages determined by both the G and P and TW3 methods were lower than mean chronological age, although the differences were not statistically significant (10.04 {+-} 3.69 years and 9.98 {+-} 3.39 years vs. 10.78 {+-} 3.96 years, respectively). Both methods had a tendency to over-estimate final height. Overall, the TW3 method seemed to be more accurate than the G and P method (mean absolute error 3.21 {+-} 2.51 years vs. 3.99 {+-} 2.99 years, respectively, P=0.048). The same method should be used when serial assessments are performed, as both methods provide similarly reliable, although not equivalent, results. The TW3 height prediction method seemed to be more accurate in patients with {beta}-thalassaemia major than the G and P method, albeit with a large confidence interval. (orig.)

The aim of the present investigation was to study the possible effects of specificity of training on muscle strength and anaerobic power in children from different sports and at different performance levels in relation to growth and maturation status. Hundred and eighty-four children of both gender participating either in swimming, tennis, team handball or gymnastics were recruited from the best clubs in Denmark. Within each sport, the coach had divided the children into an elite (E) and non-elite (NE) group according to performance level and talent. Tanner stage assessment and body weight and height measurements were performed by a physician. The anaerobic performances were assessed by Wingate tests and jumping performance in squat jump (SJ), countermovement jump (CMJ) and drop jump (DJ) from two heights. Most of the differences between groups in Wingate performance disappeared when the data were normalised to body mass. The gymnasts were the best jumpers and their superiority were increased in the more complex motor coordination tasks like DJ. The results may indicate some influence of training specificity, especially on the more complex motor tasks as DJ and there may be an effect of training before puberty. The performance in the less complex motor tasks like cycling and SJ and CMJ may also be influenced by specific training, but not to the same extent, and heritance may be an important factor for performance in these anaerobic tasks.

Numerous studies and monitoring campaigns in an aquatic medium have recorded the presence of pesticides. Generally speaking, they originate in the wash load from plant health activities in the farming sector or the manufacture and/or use of such products. Never the less, there are other causes, such as the tanning industry, as described in this article. During this industrial process, the hides releases organophosphate pesticides employed in eliminating parasites from the lambs and technical mixtures of hexachlorocyclohexane added to preserve the hides during transport. The case of the Vic area is described. This is a region of Catalonia, in Spain, where there are tanning factories, all of which have some type of pre-treatment of their waste waters as well as a biological waste water treatment plant for the local population and the factories. The influence on the receiving rivers, which have major reservoirs supplying Barcelona and other towns, is discussed. The water from these reservoirs is treated to make it fit for drinking in the Cardedeu waste water treatment plant, which pours the wash water from its filters into the river Mogent. Data are presented on the concentrations of pesticides at several points on this long route, taking note of the persistence of the pesticides. The article concludes by pointing out the need for the tanners to adapt good practices that will solve the problems they cause. (Author) 3 refs.

The aim of this study was to evaluate the effect of increasing the amount of time spent in physical education classes on bone mineral accrual and gain in bone size in prepubertal Danish children. A total of 135 boys and 108 girls, aged 6-8 years, were included in a school-based curriculum intervention program where the usual time spent in physical education classes was doubled to four classes (180 min) per week. The control group comprised age-matched children (62 boys and 76 girls) recruited from a separate community who completed the usual Danish school curriculum of physical activity (90 min/week). Dual-energy X-ray absorptiometry was used to evaluate bone mineral content (BMC; g), bone mineral density (g/cm(2)), and bone width at the calcaneus and distal forearm before and after 3 years of intervention. Anthropometrics and Tanner stages were evaluated on the same occasions. General physical activity was measured with an accelerometer worn for 4 days. In girls, the intervention group had a 12.5% increase (P = 0.04) in distal forearm BMC and a 13.2% increase (P = 0.005) in distal forearm scanned area compared with girls in the control group. No differences were found between the intervention and control groups in boys. Increasing the frequency of physical education classes for prepubertal children is associated with a higher accrual of bone mineral and higher gain in bone size after 3 years in girls but not in boys.

Methods: This retrospective study was conducted on 31 patients who underwent total gastrectomy due to gastric cancer in 2. Clinic of General Surgery, SSK Ankara Training Hospital. 6 different reconstruction methods were used and analyzed in terms of age, sex and postoperative complications. One from esophagus and two biopsy specimens from jejunum were taken through upper gastrointestinal endoscopy from all cases, and late period morphological and microbiological changes were examined. Postoperative weight change, dumping symptoms, reflux esophagitis, solid/liquid dysphagia, early satiety, postprandial pain, diarrhea and anorexia were assessed. Results: Of 31 patients,18 were males and 13 females; the youngest one was 33 years old, while the oldest- 69 years old. It was found that reconstruction without pouch was performed in 22 cases and with pouch in 9 cases. Early satiety, postprandial pain, dumping symptoms, diarrhea and anemia were found most commonly in cases with reconstruction without pouch. The rate of bacterial colonization of the jejunal mucosa was identical in both groups. Reflux esophagitis was most commonly seen in omega esophagojejunostomy (EJ, while the least-in Roux-en-Y, Tooley and Tanner 19 EJ. Conclusion: Reconstruction with pouch performed after total gastrectomy is still a preferable method. (The Medical Bulletin of Haseki 2010; 48:126-31

The alarming progression of pediatric obesity is associated with the development of sleep-disordered breathing (SDB), and both exhibit similar adverse cardiometabolic health outcomes. Physical activity level (PAL) may counteract sleep and metabolic disturbances. The present study investigates i) the association between the metabolic syndrome in childhood obesity and SDB, ii) the impact of SDB severity on cardiometabolic risk scores and PAL in children with obesity. Maturation status (Tanner stages), anthropometric (height, weight, body mass index, waist circumference, body adiposity index) and cardiometabolic characteristics (systolic and diastolic blood pressure, lipid and glycemic profiles) were assessed in 83 obese children (mean±SD, age: 10.7±2.7years). PAL and SDB were investigated with a step test and interviews, and an overnight sleep monitor, respectively. The presence or absence of metabolic syndrome (MS) was established and continuous cardiometabolic risk scores were calculated (MetScore BMI and MetScore WC ). Obese children with (61.4%) and without (38.6%) MS present similar SDB. SDB severity is associated with increased insulin concentrations, MetScore BMI and MetScore WC (pobese children. There is no association between SDB and PAL. In a context where no consensus exists for SDB diagnosis in children, our results suggest the influence of SDB severity on cardiometabolic risk factors. Further studies are needed to explore the association between PAL and both metabolic and sleep alterations in obese children. Copyright © 2016 Elsevier Inc. All rights reserved.

We wished to analyze, qualitatively and quantitatively, the noise performance of fractional anisotropy brain images along with the different diffusion gradient numbers by using the histogram method. Diffusion tensor images were acquired using a 3.0 T MR scanner from ten normal volunteers who had no neurological symptoms. The single-shot spin-echo EPI with a Stejskal-Tanner type diffusion gradient scheme was employed for the diffusion tensor measurement. With a b-valuee of 1000 s/mm 2 , the diffusion tensor images were obtained for 6, 11, 23, 35 and 47 diffusion gradient directions. FA images were generated for each DTI scheme. The histograms were then obtained at selected ROIs for the anatomical structures on the FA image. At the same ROI location, the mean FA value and the standard deviation of the mean FA value were calculated. The quality of the FA image was improved as the number of diffusion gradient directions increased by showing better contrast between the WM and GM. The histogram showed that the variance of FA values was reduced as the number of diffusion gradient directions increased. This histogram analysis was in good agreement with the result obtained using quantitative analysis. The image quality of the FA map was significantly improved as the number of diffusion gradient directions increased. The histogram analysis well demonstrated that the improvement in the FA images resulted from the reduction in the variance of the FA values included in the ROI

This article is a report on a phenomenological study of Chinese mothers' experiences of caring for their children who were living with atopic eczema. A mother's attitude and personality may have a direct influence on her child's adherence to treatment for atopic eczema. Thus, good communication between healthcare professionals and the mother is essential. Treatment and care should also be culturally appropriate. Using an interpretive phenomenological method, 14 interviews were conducted in Hong Kong, China from September 2007 to August 2008, with nine mothers caring for their children who were living with atopic eczema. Crist and Tanner's circular process of hermeneutic interpretive phenomenology was chosen to guide the data analysis. Mothers' coping patterns involved persistently dealing with enduring demands and seeking alternative therapies that were aimed at curing the disease. Four themes finally emerged from the data: (1) dealing with extra mothering, (2) giving up their life, (3) becoming an expert and (4) living with blame and worry. Mothers' coping patterns involved persistently finding ways to relieve their children's suffering with the aim of curing the disease and dealing with their own emotions related to the frustration resulting from giving up their life and living with blame and worry. The study findings provide nurses with an empathic insight into mothers' feelings and the enduring demands of caring for children with atopic eczema, and help nurses to develop culturally sensitive interventions, reinforce positive coping strategies, increase family function and improve health outcomes. © 2011 Blackwell Publishing Ltd.

As a follow-on to the first International Workshop on Residential Radon Epidemiology held in Alexandria VA, on July 24-26, 1989, a Second Workshop was convened, in Alexandria, VA, July 22-23 1991, also under the auspices of the US Department of Energy and the Commission of European Communities. The Workshop, co-chaired by Jonathan Samet and Jan Stolwijk, was attended by 20 active participants from seven countries representing epidemiologic studies recently completed, currently in progress, or in the last stages of preparation. The studies reported on are being conducted in the United States, Canada, Sweden, the United Kingdom, France, Belgium, Germany and the Peoples' Republic of China. The invited presentations that initiated the Workshop focused on a number of methodological problems that have surfaced in the last few years. Among these were: (1) the difficulties in predicting indoor radon concentrations, based on geologic information, (discussed by Alan Tanner, formerly of the US Geologic Survey); (2) the relationships between indoor radon concentrations and building characteristics (discussed by Richard Sextro, Lawrence Berkeley Laboratory, USA); (3) the approaches to analysis of case-control studies in radon epidemiology (discussed by Sarah Darby, Imperial Cancer Research Fund, UK); (4) statistical approaches to error in measurements and missing data (discussed by Donna Spiegelman, Tufts University, USA); (5) preliminary results of a data pooling effort dealing with several different studies of residential radon epidemiology and the lessons to be drawn from this effort (discussed by Jay Lubin, US National Cancer Institute)

Full Text Available OBJETIVO: Este estudo avaliou o consumo alimentar e a prevalência de excesso de peso entre adolescentes de Piracicaba, São Paulo. MÉTODOS: Estudo observacional transversal com amostra representativa de adolescentes maiores de 10 anos de 11 escolas públicas de Piracicaba. Realizou-se auto-avaliação da maturação sexual por planilhas dos estágios de Tanner. Pelo Questionário de Freqüência Alimentar Semi-Quantitativo, investigou-se o consumo de energia, macronutrientes, frutas, hortaliças e doces. Foram aferidos peso e altura para avaliação do perfil antropométrico pelos percentis de Índice de Massa Corporal e índice de altura-para-idade. RESULTADOS: Foram avaliados 390 adolescentes, com média de idade de 12,4 anos, sendo 46,4% meninos e 78,7% púberes. O consumo médio de energia foi de 3.645kcal (56,2%, 12,8% e 33,5% provenientes de carboidratos, proteínas e lipídios, respectivamente. Observou-se que 77,9% da amostra ingeria alto teor de gordura. O consumo médio de frutas, hortaliças e doces foi de 2,3, 2,4 e 4,5 porções diárias, respectivamente. Foi encontrado 21,0% de excesso de peso, 4,4% de baixo peso e 1,8% de déficit de altura-para-idade. CONCLUSÃO: Expressivo percentual de adolescentes apresentava reduzido consumo de frutas e hortaliças e consumo lipídico e de doces acima do recomendado, podendo haver relação com o elevado número de participantes com excesso de peso. Adolescentes devem ser alvo de programas que enfatizem a adoção de alimentação saudável, para diminuir risco e incidência de obesidade e prevenir futuros agravos à saúde.OBJECTIVE: This study assessed food consumption and prevalence of overweight among adolescents from Piracicaba, São Paulo, Brazil.

Full Text Available The aim of this study was to establish two new formulas for objectively evaluating skeletal maturation of cervical vertebrae in female and male Brazilian subjects using lateral cephalometric radiographs. The sample included 128 girls and 110 boys, aged 7.0 to 15.9 years, from the files of the Oral Radiology Clinic, Piracicaba Dental School, University of Campinas (Unicamp, SP, Brazil. The cervical vertebral bodies of C3 and C4 were traced and measured and regression formulas were developed in order to determine cervical vertebral bone age. Another sample of lateral teleradiographs and hand-wrist radiographs of 55 girls and 54 boys (aged 7.0 to 15.9 years was used to verify the reliability of the developed regression formulas, as compared with bone age assessed using the Tanner et al.15 (2001 Method (TW3 in hand-wrist radiographs. The analysis of both the boys’ and girls’ data (ANOVA showed no statistical difference between cervical vertebral bone age, bone age, and chronological age, indicating that these formulas can be used in this population (p = 0.5721 and p = 0.6007 for girls and boys, respectively. Female cervical vertebral bodies of C3 and C4 increased in an accelerated manner from 10 to 13 years. Analysis of the male sample showed that C3 measurements increased in an accelerated manner from 12 to 15 years. The C4 measurements, however, did not increase at all. Using cervical vertebral bone age it is possible to evaluate skeletal maturation objectively in cephalometric radiographs.O objetivo deste estudo foi estabelecer dois novos métodos para meninas e meninos brasileiros, no intuito de determinar de forma objetiva a maturação esquelética das vértebras cervicais em radiografias cefalométricas laterais.

Full Text Available OBJETIVO: Avaliar a associação de padrões alimentares com alterações metabólicas em adolescentes obesos. MÉTODOS: Estudo transversal envolvendo 76 estudantes (ambos os sexos, 14-19 anos, IMC³P95 e Tanner ³4 de escolas públicas da cidade de São Paulo, Brasil. Foram coletados dados antropométricos e bioquímicos, e aplicados questionários com informações sociodemográficas e registro alimentar de 4 dias, entre 2006 e 2007. Escores fatoriais foram obtidos na análise fatorial e, após ajustes, três padrões alimentares identificados foram associados a fatores de risco biológico por regressão linear múltipla. RESULTADOS: O padrão Tradicional (arroz e massas, feijões, carnes vermelhas, embutidos, óleos e doces foi positivamente associado com insulina, glicemia e triglicérides e negativamente associado com lipoproteína de alta densidade. O padrão Em Transição (peixe, aves, ovos, pães, manteiga, leite e derivados, hortaliças, frutas, sucos de frutas e açúcar refinado apresentou as mesmas associações, além de associação similar com a pressão arterial diastólica. O padrão Fast Food (cafeteria, hambúrguer, maionese, bolacha, bolos e tortas, chocolate e refrigerantes apresentou associação positiva com o colesterol, lipoproteína de baixa densidade e pressão arterial sistólica e diastólica, e associação negativa com insulina e lipoproteína de alta densidade. CONCLUSÃO: Os padrões Tradicional e Em transição apresentaram associações diferentes com o metabolismo lipídico e glicídico quando comparados com o padrão Fast Food. Os três padrões podem ser considerados obesogênicos, porém o padrão Fast Food pareceu ser o mais aterogênico e promotor de hipertensão arterial.OBJECTIVE: This study assessed the association between dietary patterns and metabolic changes in obese adolescents.

Constitutional delayed growth (CDG is defined as that condition in which height is below the third percentile in Tanner Whitehouse growth curves, associated to a similar delay in skeletal maturity (Greulich and Pyle Atlas, and to the absence of deficiencies of Growth and Thyroid hormones or of nutritional and psychosocial conditions. The subjects of this study were 15 boys and 6 girls (age 13.4 :t: 3.1 years, range 10.9-16. Thirteen boys and 1 girl were at a prepuberal stage of development at the beginning of the study. In order to check the spontaneous growth velocity (GV, the patients were followed for a four-month period before starting any treatment. The boys under 13 years and all the girls received clonidine during a 4-12 month period (0.1 mg/m2/day. With this drug the boys Increased their GV from 5.9 :t 3.12 cm/year to 7.04 :t 2.23 cm/year (NS, and the girls from 5.53 :t 2.31 to 6.45 :t 1.18 cm/year (NS. However, two subgroups were clearly differentiated: the children who had some response to clonidine and those who did not. In the boys that responded, the spontaneous GV before clonidine was significantly less than that of those who did not respond (3.8 :t 3.27 vs 7.67 :t 1.66 cm/year (P< 0.05. The figures for the girls were 3.5 :t 0.86 and 7.57 :t 0.4 cm/year, respectively (P< 0.01 . Nine boys received Testosterone Enantate (250 mg I.M./month for four doses; five of them had previously received clonidine. The GV before Testosterone, 5.0 :t 2.59 compared to post-testosterone, 9.26 :t 2.4 cm/year was significantly lower (P< 0.01 . The delay In skeletal maturation, as defined by the bone age/chronological age Index, dld not have any bearing on the eventual response to clonldine, nor this response was attributable to a progress In the sexual maturity index (Tanner during treatment with clonidine. We conclude that a subnormal spontaneous GV (Iess than 4 cm/year in these
