    The present experiment had two purposes: (i) to study crystalline amino acid supplementation to crude protein-reduced diets, and (ii) to study the effect of different isoleucine (Ile) to lysine (Lys) and valine (Val) to Lys ratios in diets for young pigs. A total of 145 pigs were weaned at 28 days...... and fed one of 5 diets for a total of 4 weeks. Two basal diets were formulated to provide crude protein in levels either as recommended (positive reference diet, PRD), or below recommendations (negative reference diet, NRD). The basal diets contained 95% of recommended Lys, and all other essential amino...... acids were provided proportionally to Lys. The NRD diet contained 0.53 Ile and 0.61 Val relative to Lys. This diet was supplemented with either Ile (0.61 of Lys) or Val (0.72 of Lys), or both Ile and Val, in order to make up the 5 diets. Supplementation with Ile to the NRD diet did not improve (P>0...

    The goal of this pilot study was to ascertain the effectiveness of an occupation-based after-school program for improving self-concept in children, ages five through eight. Fifty-four randomly selected children ages five through eight from two schools (one being the control group) with similar socioeconomic status along the Ohio River were involved in this research study. The Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PCSA; Harter & Pike, 1984) was administered to all participants (N = 54), four subtests were analyzed: cognitive competence, social competence with peers, physical competence in sports, and maternal acceptance. The experimental group (n = 25) attended occupation-based groups two times a week after school. The control group (n = 29) did not participate in an after-school program. Data from pre-test and post-test were analyzed using a t-test. Findings demonstrated that the experimental group improved their self-concept scores when compared to the control group in the areas of peer acceptance and cognitive competence. This would offer tentative evidence that an after-school program directed by occupational therapists that is designed to improve self-concept may be successful.

    Full Text Available Background: The goal of the present study was to develop and validate the Persian version of the Acceptable Noise Level (ANL test in normal, Persianspeaking children aged 5-8 years. Methods: This tool-making and non-experimental research was conducted in two stages. In the first stage the proper story was selected and recorded after evaluation of its content validity. In the second stage this test material was administered to a total 181 normal children (97 girls and 84 boys randomly chosen from the population of preschool and primary school children of Tehran (District 5, aged 5-8 years in four age groups to evaluate the reliability of test in order to develop the Persian version of the ANL test and assess its changes during the growth. Lawshe’s method and Cronbach’s alpha coefficient were used to assess the content validity and reliability of the test, respectively. Mann– Whitney U test was used to examine gender differences, and Kruskal-Wallis test was to examine age differences. Results: Test-retest correlation of 0.74 indicated acceptable reliability of the test. Significant differences were found between most of different age groups for the ANL mean scores (P0.05. Conclusion: The study results indicated good validity and reliability of the Persian version of the ANL test in children. Therefore this test can be useful in designing classrooms suitable for 5-8 year-old children of both genders.

    Increased skin surface pH is an important host-related factor for deteriorated barrier function in the aged. We investigated whether restoration of the skin pH through topical application of a water-in-oil (w/o) emulsion with pH 4 improved the barrier homeostasis in aged skin and compared the effects to an identical galenic formulation with pH 5.8. The effects of the test formulations on the barrier recovery were investigated by repeated measurements of transepidermal water loss (TEWL) and skin pH 3 h, 6 h and 24 h after acetone-induced impairment of the barrier function in aged skin. The long-term effects of the pH 4 and pH 5.8 emulsions were analyzed by investigation of the barrier integrity/cohesion, the skin surface pH and the skin roughness and scaliness before and after a 4-week, controlled application of the formulations. The application of the pH 4 emulsion accelerated the barrier recovery in aged skin: 3 h and 6 h after acetone-induced barrier disruption the differences in the TEWL recovery between the pH4-treated and acetone control field were significant. Furthermore, the long-term application of the pH 4 formulation resulted in significantly decreased skin pH, enhanced barrier integrity and reduced skin surface roughness and scaliness. At the same time points, the pH 5.8 formulation exerted only minor effects on the barrier function parameters. Exogenous acidification through topical application of a w/o emulsion with pH 4 leads to improvement of the barrier function and maintenance of the barrier homeostasis in aged skin.

    To investigate the differential association of three modes (fussing, crying, unsoothable crying) and three properties (duration/day, frequency/day, maximum bout length) of infant distress with daily caregiver frustration. Replicated cross-sectional studies were completed in Vancouver, British Columbia (n = 1065) and Seattle, Washington (n = 1857). Infant fussing, crying, and unsoothable crying and caregiver frustration were measured daily for 4 days at 5 weeks of age by the Baby's Day Diary. Generalized estimating equation models were used to predict caregiver frustration from nine measurements of distress. In Vancouver, measurements of distress significantly associated with caregiver frustration in decreasing order of magnitude were as follow: (1) maximum bout length of unsoothable crying; (2) duration/day of crying; and (3) frequency of unsoothable crying and duration/day of fussing. In Seattle, associated measurements of distress were: (1) maximum bout length of unsoothable crying; (2) maximum bout length and duration/day of crying, frequency of unsoothable crying, and duration/day of fussing; and (3) frequency/day of crying. Daily caregiver frustration is associated differentially with different modes and properties of infant distress. Specifically, maximum bout length of unsoothable crying was most strongly related in both sites. Additionally, frequency/day of unsoothable crying and duration/day of crying and of fussing were significantly associated at both sites. Copyright © 2011 Mosby, Inc. All rights reserved.

    The purpose of this study was to evaluate on a longitudinal basis, the changes in intercanine and intermolar widths over a 45-year span. The subjects in this study were from two pools of normal persons: (1) 28 male and 33 female infants evaluated longitudinally at approximately 6 weeks, 1 year, and 2 years of age (before the complete eruption of the deciduous dentition); and (2) 15 male and 15 female subjects from the Iowa facial growth study evaluated at ages 3, 5, 8, 13, 26, and 45. Arch width measurements on maxillary and mandibular dental casts were obtained independently by two investigators. Intraexaminer and interexaminer reliability were predetermined at 0.5 mm. From the findings in the current study, the following conclusions can be made: (1) Between 6 weeks and 2 years of age, i.e., before the complete eruption of the deciduous dentition, there were significant increases in the maxillary and mandibular anterior and posterior arch widths in both male and female infants. (2) Intercanine and intermolar widths significantly increased between 3 and 13 years of age in both the maxillary and mandibular arches. After the complete eruption of the permanent dentition, there was a slight decrease in the dental arch widths, more in the intercanine than in the intermolar widths. (3) Mandibular intercanine width, on the average, was established by 8 years of age, i.e., after the eruption of the four incisors. After the eruption of the permanent dentition, the clinician should either expect no changes or a slight decrease in arch widths. In conclusion, although the dental arch widths undergo changes from birth until midadulthood, the magnitude as well as the direction of these changes do not provide a scientific basis for expanding the arches, in the average patient, beyond its established dimensions at the time of the complete eruption of the canines and molars. Both patients and clinicians should be aware of these limitations.

    Behaviour of broilers up to 6 weeks of age has been studied extensively, but little is known what happens after 6 weeks. Insight in the behavioural abilities after 6 weeks may also yield insight in the period before 6 weeks as the disbalance between motivation and physical abilities is more clearly

    To study outcome of low-risk moderately preterm birth between 32 and 36/7 weeks' gestation. 377 Moderately preterm children (M: 34.7, SD: 1.2 complete weeks), without need for neonatal intensive care and without dysmaturity or congenital malformations, were compared with 182 term children and assessed at eight years (M: 8.9, SD: 0.54). School situation, IQ, sustained attention, behavior problems, and attention-deficit/hyperactivity characteristics were studied. Special education was attended by 7.7% of the moderately preterm children, more than twice the rate of 2.8% in the general Dutch population of this age. Additional exploration for two preterm subgroups of 32 to 33 versus 34 to 36 weeks' gestation showed a need for special education in 9.7% versus 7.3% and a significant difference in grade retention for 30% versus 17%, respectively. Of the children attending mainstream primary schools, grade retention was found in 19% of the preterm versus 8% of the comparison children. Adjusting for maternal education, a group difference of 3 points was found in IQ. The preterm children needed more time for the sustained attention task. The preterm children had more behavior problems (specifically internalizing problems with 27% scoring above the borderline cut-off), as well as more attention-deficit/hyperactivity disorder characteristics (specifically attention deficits). Cognitive and emotional regulation difficulties affect functioning of moderately preterm children, as school problems, a slightly lower IQ, attention and behavioral problems are found when they are compared with term-born children. Identification and monitoring of precursors of these problems at younger age is needed in view of prevention purposes.

    White Leghorn pullets were fed rations in which the protein supplementary to that provided by the grain portion of the ration was derived from soybean meal, meat and bone meal, anchovy fish meal or cottonseed meal from 8 to 21 weeks of age. Protein levels were varied so that each protein supplement was tested in a feeding program in which pullets received 16% protein diets from 8 to 14 weeks and 14% protein from 14 to 21 weeks and in another feeding program in which 14% protein was fed from 8 to 14 weeks and 12% protein from 14 to 21 weeks. Each of the developing rations contained sufficient nutrient to enable pullets to develop and attain high rate of laying performance. The 14% and 12% protein cottonseed meal diets contained only 0.50% and 0.45% lysine respectively. Thus the lysine requirement of White Leghorn pullets from 8 to 14 weeks and from 14 to 21 weeks is not over 0.50% and 0.45% respectively.

    OBJECTIVE: To examine the relationship between gestational age and mental and psychomotor development scores in healthy infants born between 37 and 41 weeks. METHODS: The cohort included 1562 participants enrolled during infancy in an iron deficiency anemia preventive trial in Santiago, Chile. All participants were healthy, full-term (37–41 weeks) infants who weighed 3 kg or more at birth. Development at 12 months was assessed using the Bayley Scales of Infant Development. Using generalized linear modeling, we analyzed the association between gestational age and 1-year-old developmental status, taking into account potential confounders including birth weight percentile, gender, socioeconomic status, the home environment, iron status, and iron supplementation. RESULTS: For each additional week of gestation, the Mental Development Index increased by 0.8 points (95% confidence interval = 0.2–1.4), and the Psychomotor Development Index increased by 1.4 points (95% confidence interval = 0.6–2.1) controlling for birth weight percentile, gender, socioeconomic status, and home environment. CONCLUSIONS: In a large sample of healthy full-term infants, developmental scores obtained using the Bayley Scales of Infant Development at 12 months increased with gestational age (37–41 weeks). There is increasing evidence that birth at 39 to 41 weeks provides developmental advantages compared with birth at 37 to 38 weeks. Because cesarean deliveries and early-term inductions have increased to 40% of all births, consideration of ongoing brain development during the full-term period is an important medical and policy issue.

    To describe the neurodevelopmental outcome and perinatal factors associated with favorable outcome among extremely preterm children at 3 years of age. All infants born before 26 weeks of gestation between 2007 and 2011, admitted to intensive care units participating in a French regional network (western PACA-southern Corsica) were included. Perinatal data were collected to assess the main neonatal morbidities. At 3 years of age, the children's neurodevelopment was assessed by trained physicians participating in the follow-up network. Children were classified according to their disability: none, moderate, or severe. Using logistic regression, we determined the perinatal factors associated with the absence of disability at 3 years of age. One hundred and sixty-two very preterm newborns were admitted to neonatal intensive care units. At discharge the survival rate was 62% (101). Rates of survival increased with gestational age (33% at 23 weeks, 57% at 24 weeks and 68% at 25 weeks). Among the 101 surviving extremely preterm children, 66 were evaluated at 3 years. The perinatal characteristics were not significantly different from those of the children lost to follow-up. Overall, 56% of extremely preterm children had no disability and 6% had severe disability. Cerebral palsy was diagnosed in 13% of children. At 3 years of age, the main perinatal factors associated with no disability were short duration of mechanical ventilation (OR=0.96 [0.93-0.99]; P=0.03) and complete course of prenatal corticosteroids (OR=4.7 [1.2-17.7]; P=0.02). As mortality rates continue to decrease for very preterm infants, concerns are rising about their long-term outcome. In this high-risk population, improving perinatal care remains a challenge to improve long-term outcome. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The aim of this study was to detail the incidence of cerebral palsy in children born before 32 weeks of gestation and to evaluate the scholastic and intellectual performance in non-handicapped children. The population included 63 survivors hospitalized in 1984-85 (gestational age: 30.06 +/- 1.21 weeks; birth weight: 1386 +/- 267 g; inborn 60%; male: 38.7%; small for gestational age: 4.8%; hyaline membrane disease: 32%; European: 98.4%). Neurodevelopmental assessment was performed by pediatricians and psychologists using Wisc-R, visual screening by Monoyer scale, hearing by audiometry realized by oto-rhinolaryngologists. There were 62 survivors (one child dead by sudden infant death syndrome). Fifty children evaluated at a mean age of 9.3 +/- 0.7 years and written data available for another eight. Twelve children presented with cerebral palsy. Risk factors were ultrasound abnormalities of parenchymal brain and male gender. In children without cerebral palsy, we observed 12 visual and two hearing impairment. Three were in special education, 32 were in an age-appropriate level, nine with one year below. Neonatal events were not associated with the Wisc-R results except for ultrasound abnormalities of parenchymal brain. Wisc-R was strongly correlated with familial economic and education level. School performances in non-handicapped children born before 32 weeks is satisfying. Intellectual performance is mainly correlated with familial economic and education level.

    Full Text Available Aim. To find predictive and indicative markers of risk for development of retinopathy of prematurity (ROP and its progression to the stage requiring laser treatment, in premature infants whose gestational age (GA was under 33 weeks. Methods. We retrospectively reviewed medical records of 197 premature infants born in 2005–2010 whose GA<33 weeks and underwent eye screening at Keio University Hospital. The association between candidate risk factors and development or progression of ROP was assessed. Results. Among the 182 eligible infants (median GA, 29.1 weeks; median birth weight (BW, 1028 g, 84 (46% developed any stage of ROP, of which 45 (25% required laser treatment. Multivariate analysis using a stepwise method showed that GA (P=0.002; 95% confidence interval (CI, 0.508–0.858, BW (P<0.001; 95% CI, 0.994–0.998, and lower maternal age (P=0.032; 95% CI, 0.819–0.991 were the risk factors for ROP development and GA (P<0.001; 95% CI, 0.387–0.609 and lower maternal age (P=0.012; 95% CI, 0.795–0.973 were for laser treatment. The odds ratio of requiring laser treatment was 3.3 when the maternal age was <33 years. Conclusion. ROP was more likely to be developed and progressed in infants born from younger mother and low GA.

    To compare the motor development of patients with hypoplastic left heart syndrome (HLHS) and other types of univentricular heart (UVH) with peers who are healthy at the ages of 16 and 52 weeks. Motor development was assessed with the Alberta Infant Motor Scale (AIMS). Both the 23 patients with HLHS and the 13 patients with UVH had lower total AIMS scores in both observations than the controls. At the age of 52 weeks, patients with HLHS had significantly lower scores in all 4 AIMS subscales, whereas patients with UVH had lower scores only in the prone and standing subscales. Motor development of patients with HLHS or UVH is delayed during the first year of life, especially in the prone and standing subscales.

    Background Exercise has been shown to be effective in cardiovascular endurance in the elderly. We studied the effect of Thai dancing on physical performance of Thai elderly. Methods This was an open-labeled, randomized intervention study. The Thai dancing group exercised for 40 minutes three times a week for 6 weeks. Physical performance ability was the primary outcome, including a 6-minute walk test (6MWT), five-times sit-to-stand (FTSST), and a sit-and-reach test measured before and after 6 weeks of intervention. Results There were 42 subjects enrolled in the study, and 38 female subjects completed (20 in Thai dance group, 18 controls), with an average age of 65.8 ± 5.1 years. The Thai dance group had significantly better physical performance in all measurements at the end of the study. The 6MWT was longer (416.7 ± 58.7 versus 345.7 ± 55.1 m; P = 0.011), FTSST was quicker (10.2 ± 1.5 versus 14.4 ± 3.3 seconds; P dance group than the control group. Conclusion Thai dance can improve physical performance in recently aged (elderly) female adults. PMID:23950640

    Trunk flexibility may be associated with arterial stiffness in young, middle-aged, and older healthy men after adjusting for blood pressure. This study assessed the effects of 4 weeks of regular static stretching on arterial stiffness in middle-aged men. Sixteen healthy men (43 ± 3 years) were assigned to control or intervention groups (n = 8 each). The control group did not alter their physical activity levels throughout the study period. The intervention group participated in five supervised stretching sessions per week for 4 weeks. Each session comprised 30 min of mild stretching that moved the major muscle groups through the full range of motion and stretches were held three times for 20 s at the end range. Flexibility was assessed by sit-and-reach test. Arterial stiffness was assessed by brachial-ankle pulse wave velocity (baPWV) and cardio-ankle vascular index (CAVI). Four weeks of stretching increased sit-and-reach (Control, Pre: 31.4 ± 2.1, Post: 30.8 ± 2.7 vs. Intervention, Pre: 30.6 ± 5.3, Post: 43.9 ± 4.3 cm), and reduced baPWV (Control, Pre: 1204 ± 25, Post: 1205 ± 38 vs. Intervention, Pre: 1207 ± 28, Post: 1145 ± 19 cm/s) and CAVI (Control, Pre: 7.6 ± 0.3, Post: 7.5 ± 0.3 vs. Intervention, Pre: 7.7 ± 0.2, Post: 7.2 ± 0.2 units) in the intervention group. However, the change in sit-and-reach did not significantly correlate with the changes in arterial stiffness. These findings suggest that short-term regular stretching induces a significant reduction in arterial stiffness in middle-aged men.

    Apnea of prematurity (AoP) is, in part, a reflection of brainstem-mediated respiratory control system maturation. We previously demonstrated changes in brainstem function in relation to hyperbilirubinemia (bilirubin encephalopathy, (BE)) as evaluated by auditory brainstem evoked responses (ABR) in infants 28 to 32 weeks gestational age (GA). We hypothesized that in this population, as bilirubin increases and causes auditory brainstem dysfunction, respiratory control system may also be adversely affected leading to increased frequency of AoP. We studied 100, 28 to 32 weeks GA infants and identified 66 with normal and 34 with abnormal ABR progression in temporal relation to hyperbilirubinemia (BE). The abnormal ABR progression was associated with elevated bilirubin, specifically elevated unbound bilirubin levels. A blinded, retrospective chart review quantified the amount of weekly apnea and bradycardia events during the hospital stay, total duration of methylxanthine treatment, total duration of mechanical ventilation, CPAP, and/or nasal cannula, and risk factors for apnea (sepsis, IVH grade >II, asphyxia). Since mechanical ventilation confounds the identification of apnea, infants requiring mechanical ventilation were excluded from further review (n = 60; 21 with BE and 39 with normal ABR progression). Data from the remaining 40 infants were analyzed. Student's t-test was used to analyze continuous variables if the distribution was normal otherwise Wilcoxon-ranked-sum test was used. chi(2) was used to analyze nominal variables. A p apnea and bradycardia between infants with and without BE was most pronounced during the first week. Premature infants with transient bilirubin encephalopathy as defined by abnormal ABR progression in relation to hyperbilirubinemia have more concurrent apneic events and require more prolonged respiratory support and medications.

    Full Text Available Two-hundred sixteen white laying hens were used to assess the ideal ratio of digestible threonine:lysine in diets for laying hens at 24 to 40 weeks of age. Birds were assigned to a randomized block design, with six treatments, six replicates per treatment and six birds per experimental unit. The cage was used as the blocking criterion. Experimental diets contained different digestible threonine:digestible lysine ratios (65, 70, 75, 80, 85 and 90% with 142 g/kg of crude protein. Experimental diets were formulated to be isonitrogenous and isocaloric with different contents of L-glutamic acid. Feed intake (g/hen/d, egg production (%, egg weight (g, egg mass (g/hen/d, feed conversion ratio (kg/dozen and kg/kg egg, eggshell weight (g, albumen weight (g, yolk weight (g and body weight gain (g were assessed. The maximum egg production was observed at 78% digestible threonine:digestible lysine ratio, while the best values of feed conversion ratio (kg/dozen egg and feed conversion ratio (kg/kg of egg were observed at 77.6% and 75%, respectively. Feed intake, egg mass and egg contents (yolk, albumen and eggshell were not affected by treatments. The estimated digestible threonine:digestible lysine ratio of Hy-Line W36 laying hens at 24 to 40 weeks of age is 78%, corresponding to 5.70 g/kg of dietary digestible threonine.

    Polyhydramnios carries a high rate of complications during pregnancy and adverse perinatal outcomes. We could find no studies of this condition in a large Asian population. The aim of this investigation was to evaluate the risks of adverse perinatal outcomes in a large study population with polyhydramnios without associated fetal anomalies after the gestational age of 20 weeks in Taiwan. We retrospectively reviewed the computerized records of women who had babies without associated fetal anomalies after the gestational age of 20 weeks at Chang Gung Memorial Hospital from July 1990 to December 2001. Possible confounding factors that could affect the occurrence of polyhydramnios were analyzed. We then investigated the relative risks of these events to adverse perinatal outcome by adjusting the variants. Significantly higher incidences of preeclampsia, placental abruption, placenta accreta, past history of fetal death or preterm delivery, multiple pregnancy, bodyweight gain > or = 20kg during pregnancy and primiparity were noted in patients with polyhydramnios than in patients without this condition. The presence of polyhydramnios significantly increased the rate of preterm delivery, low birth weight or very low birth weight, low one- and five-minute Apgar scores, fetal death, large for gestational age babies, meconium-stained amniotic fluid, Cesarean section, fetal distress in labor, NICU transfer and neonatal death. Polyhydramnios carried a higher incidence of adverse perinatal outcomes, such as low Apgar scores, fetal death, fetal distress in labor, NICU transfer and neonatal death, despite exclusion of congenital anomalies from the study population. Detailed antepartum fetal well-being surveillance, intensive intrapartum monitoring and further attention postpartum are warranted in patients with this condition.

    The purpose of this study was to examine the influence of prone and supine position in preterm infants during acute pain of blood collection. Level III Neonatal Intensive Care Unit (NICU). Thirty-eight preterm infants (birthweight 1339 [590-2525] g, GA 29 [25- 32] wks) were in 2 groups depending on their position in the isolette prior to and during heel lance at 32 weeks post-conceptional age. The study design was a comparison between groups (Prone, Supine) during 2 events (Baseline, Heel lance). Pain measures were multidimensional, including behavioral (sleep-wake state and facial activity) and physiological (heart rate) responses measured continuously prior to (Baseline) and during blood collection (Lance). Both groups of infants displayed statistically significant shifts in sleep-wake state to greater arousal, and increased facial activity and heart rate, from Baseline to Lance. Prone position was associated with significantly more deep sleep during Baseline, compared with Supine position, but there were no differences in sleep-wake state during Lance. Minor increased facial activity was shown in some time segments of Baseline for infants in Supine compared with Prone, but did not differ overall between positions. Prone and Supine position did not affect heart rate significantly during Baseline or Lance events. Prone position promotes deep sleep in preterm neonates at 32 weeks post-conceptional age when they are undisturbed. However, placement in prone position is not a sufficient environmental comfort intervention for painful invasive procedures such as heel lance for blood sampling in the NICU. Neonates require other environmental supports to promote coping with this stressful event.

    o assess associations of caesarean section with body mass from birth through adolescence. ongitudinal birth cohort study, following subjects up to 15 years of age. Children born in 1991-1992 in Avon, UK who participated in the Avon Longitudinal Study of Parents and Children (ALSPAC) (n=10 219). standardized measures of body mass (weight-for length z-scores at 6 weeks, 10 and 20 months; and body mass index (BMI) z-scores at 38 months, 7, 9, 11 and 15 years). Secondary outcome: categorical overweight or obese (BMI: 85th percentile) for age and gender, at 38 months, 7, 9, 11 and 15 years. Of the 10 219 children, 926 (9.06%) were delivered by caesarean section. Those born by caesarean had lower-birth weights than those born vaginally (-46.1 g, 95% confidence interval(CI): 14.6-77.6 g; P=0.004). In mixed multivariable models adjusting for birth weight, gender, parental body mass, family sociodemographics, gestational factors and infant feeding patterns, caesarean delivery was consistently associated with increased adiposity, starting at 6 weeks (+0.11 s.d. units, 95% CI: 0.03-0.18; P=0.005), through age 15 (BMI z-score increment+0.10 s.d. units, 95% CI: 0.001-0.198; P=0.042). By age 11 caesarean-delivered children had 1.83 times the odds of overweight or obesity (95% CI: 1.24-2.70; P=0.002). When the sample was stratified by maternal pre-pregnancy weight, the association among children born of overweight/obese mothers was strong and long-lasting. In contrast, evidence of an association among children born of normal-weight mothers was weak. Cesarean delivery is associated with increased body mass in childhood and adolescence. Research is needed to further characterize the association in children of normal weight women. Additional work is also needed to understand the mechanism underlying the association, which may involve relatively enduring changes in the intestinal microbiome.

    Full Text Available The biological material which was studied has been represented by 34 ROSO SL hybrid that lay eggs, of 45 weeks of age. We have analyzed the 45 weeks age as a middle age for the intensity of egg laying on the level of over 80%. Measurements have been made for the following conformation traits: body weight, body length, former depth, former width, pelvis width, length of the breast-bone careen, thoracic perimeter, shin perimeter and length. The measurements have been made according to the methodology and the known speciality instruments. The observation data have been overworked, this way we have established the average values and the variability parameters for the traits we followed, which fit the values presented in the specialty literature and are even over these for the age group chosen for studies. The body weight of 2058.82 ± 38.49 g, superior to the one mentioned in the technological guide, confirms a proper unrolling of the body weight deposits and shows that the Roso SL hybrid will properly support both the body growth in weight and also egg production in parallel, respectively this double effort, fact that gives the hybrid a higher quality. Other registered values are of 18.06 ± 0.15 for the body length, of 10.85 ± 0.11 cm for the length of the breastbone careen, together with the sizes which maintain a proper egg production, such as the width of the pelvis of 9.75 ± 0.14, the former width of 6.78 ± 0.10 cm and, why not, even the former depth of 10.72 ± 0.12. We would also notice an appreciable uniformity of these values, the limits of the variation factor being between 4.66 (length of the shin and 8.36 (former width. The values that the biological material represent for the characters we studied, convince us about the hybrid’s availability for being exploited in the egg production.

    Two independent studies assessed the duration of immunity of an inactivated adjuvanted Mycoplasma hyopneumoniae vaccine against mycoplasmal pneumonia in seronegative (study A, n=52) and seropositive (study B, n=52) pigs. The pigs were allocated randomly to treatment and were then injected with a single dose of either the vaccine or a placebo at approximately 1 week of age. Twenty-five weeks after treatment administration, the pigs were challenged with a virulent strain (LI 36, Strain 232) of M. hyopneumoniae and the extent of lung lesions consistent with mycoplasmal pneumonia was assessed 4 weeks later. In study A, the geometric mean lung lesion score (expressed as least squares mean percentages of lung lesions) was significantly (P=0.0001) lower in vaccinated (0.3%, n=20) than in control pigs (5.9%, n=24) seronegative to M. hyopneumoniae at enrolment; similarly, in study B, the extent of lung lesions was significantly reduced (P=0.0385) in seropositive vaccinated pigs (2.0%, n=22) compared to controls (4.5%, n=26). At the end of the investigation period, 4 weeks after challenge, mean antibody sample-to-positive (S/P) ratios were significantly higher both in seronegative (P=0.0012) and seropositive (P=0.0001) vaccinated pigs (mean values=0.77 and 0.81, respectively) than in controls (mean values=0.51 and 0.38, respectively).

    Language development is often slower in preterm children compared with their term peers. We investigated factors associated with vocabulary acquisition at 2 years in a cohort of children born at 28 weeks' gestation or less. For children entered into the United Kingdom Oscillation Study, language development was evaluated by using the MacArthur-Bates Communicative Development Inventories score, completed by parents as part of a developmental questionnaire. The effect of demographic, neonatal, socioeconomic factors, growth, and disability were investigated using multifactorial random effects modelling. Questionnaires were returned by 288 participants (148 males, 140 females). The mean number of words vocalized was 42 (SD 29). Multifactorial analysis showed only four factors were significantly associated with vocabulary acquisition. These were: (1) level of disability (mean words: no disability, 45; other disability, 38; severe disability, 30 [severe disability is defined as at least one extreme response in one of the following clinical domains: neuromotor, vision, hearing, communication, or other physical disabilities]; 95% confidence interval [CI] for the difference between no and severe disability 7- 23); (2) sex (39 males, 44 females; 95% CI 0.4-11); (3) length of hospital stay (lower quartile, 47; upper quartile, 38; 95% CI -12 to -4); and (4) weight SD score at 12 months (lower quartile, 39; upper quartile, 44; 95% CI 1-9). There was no significant association between gestational age and vocabulary after multifactorial analysis. There was no significant effect of any socioeconomic factor on vocabulary acquisition. We conclude that clinical factors, particularly indicators of severe morbidity, dominate the correlates of vocabulary acquisition at age 2 in children born very preterm.

    Full Text Available Two hundred and fifty-two Hy-Line W36 laying hens were allotted in a completely randomized design with 6 treatments, 7 replicates and 6 hens per experimental unit in order to determine the ideal ratio of isoleucine (Ile in relation to lysine (Lys to laying hens aged 42-58 weeks. Experimental diets contained digestible Ile at different levels, resulting in different Ile:Lys ratios (0.73:1; 0.78:1; 0.83:1; 0.88:1; 0.93:1 and 0.98:1. A basal diet was formulated to provide Isoleucine in levels below recommendations. This diet was supplemented with L-isoleucine to make up the 6 diets. Each diet was made isonitrogenous by varying the dietary contents of glutamic acid and isocaloric by adjusting the contents of cornstarch. All essential amino acids were provided proportionally to lysine. Egg production, egg weight, egg mass, feed conversion ratio, albumen, yolk and eggshell contents were recorded and compiled at every 28-day period. No differences were observed in the performance over a wide range of dietary isoleucine concentrations from 5.76 to 7.73 g/kg corresponding to 0.73:1 to 0.98:1 Ile:Lys ratios. The lowest Ile:Lys ratio (0.73:1 was sufficient to ensure satisfactory performance of birds, corresponding to the consumption of 534 mg of isoleucine and 731 mg of lysine/day.

    The early postnatal development of functional corticospinal connections in human infants is not fully clarified. We used EEG and EMG to investigate the development of corticomuscular and intramuscular coherence as indicators of functional corticospinal connectivity in healthy infants aged 1...... for infants younger than 9 weeks, whereas a short-lasting (10-20 ms) central peak was observed for EMG-EMG synchronization in older infants. This peak was largest for infants aged 9-25 weeks. These data suggest that the corticospinal drive to lower and upper limb muscles shows significant developmental...... changes with an increase in functional coupling in infants aged 9-25 weeks, a period which coincides partly with the developmental period of normal fidgety movements. We propose that these neurophysiological findings may reflect the existence of a sensitive period where the functional connections between...

    There is insufficient information regarding acute pain reactions among premature infants with a gestational age of less than 26 weeks and no appropriate scale for pain measurement in this age group. We hypothesized that these infants present specific reactions to a standardized pain stimulus within the first 3 days of life. Mixed-methods, prospective, open-label, single-arm, observational study. Routine capillary or peripheral blood takes were filmed. The model consisting of a baseline, a preparatory, an interventional and a return-to-baseline phase was filmed. After a pilot evaluation, experienced medical and nursing neonatal intensive care unit (NICU) staff analysed the videos. Twenty infants with gestational ages ranging from 22 weeks and 3 days to 26 weeks (mean 24 weeks) were recruited. Nineteen infants showed pain reactions, with a mean latency of 8.3 s (range 2-30). The majority presented eye movements, changes of the breath pattern and a slight increase in the mean SpO2 value. A high degree of interrater and intrarater reliability was found. Premature infants with a gestational age of up to 26 weeks can present a variety of discrete reactions as response to a pain stimulus within the first 72 h of life. Experienced NICU staff can perform a valid and reliable evaluation of these reactions. © 2016 S. Karger AG, Basel.

    Full Text Available This study investigated the onset of age-related changes in the myocardial antioxidant enzymes and apoptosis and the vulnerability of the myocardium to oxidative stress following exercise training. Few studies have investigated the influence of the most prevalent life-prolonging strategy physical exercise, on the age increment alterations in the myocardial antioxidant enzymes and apoptosis at mid age and to determine whether exercise-induced antioxidant defense system could attenuate lipid peroxidation. Thirty six male Wistar rats were randomly assigned to exercise trained (n = 18 and sedentary (n = 18 groups. The rats in the training group went under 12, 24 and 36 weeks of moderate exercise trainings (25 m·min-1 for 60-min with a 0% slope. Six sedentary controls were killed together with each exercise group at the end of the training programs. Levels of thiobarbituric acid-reactive substances (TBARS and catalase (CAT activity in myocardial homogenates were unchanged by training irrespective of the protocol duration. However, an increased content of the TBARS was detected in hearts from both the 24 and 36-week trained and sedentary control rats when compared with their corresponding 12-week groups (p<0.01. The activity of superoxide dismutase (SOD remained unchanged after the 12-week training period whereas a significant increase was observed in heart homogenates of 24-week trained animals as compared with their sedentary controls (p<0.05. The activity of glutathione peroxidase (GPX remained unchanged. The rates of apoptosis which was detected by ELISA assays, were significantly modified after 24 and 36-week of training (p<0.05. These results demonstrate that a long-term endurance training (24 weeks induced increases in SOD activities in rat myocardium and elicited a marked reduction in apoptosis rate. However, a shorter training program (12 weeks was not effective in increasing heart antioxidant defenses

    The purpose of this study was to determine the effectiveness of a 4-week running sprint interval training protocol to improve both aerobic and anaerobic fitness in middle-aged adults (40-50 years) as well as compare the adaptations to younger adults (20-30 years). Twenty-eight inactive participants - 14 young 20-30-year-olds (n = 7 males) and 14 middle-aged 40-50-year-olds (n = 5 males) - completed 4 weeks of running sprint interval training (4 to 6, 30-s "all-out" sprints on a curved, self-propelled treadmill separated by 4 min active recovery performed 3 times per week). Before and after training, all participants were assessed for maximal oxygen consumption (VO2max), 2000 m time trial performance, and anaerobic performance on a single 30-s sprint. There were no interactions between group and time for any tested variable, although training improved relative VO2max (young = 3.9, middle-aged = 5.2%; P training on the 30-s sprint test. The current study demonstrates that a 4-week running sprint interval training programme is equally effective at improving aerobic and anaerobic fitness in younger and middle-aged adults.

    The purpose of this study was to determine the effectiveness of an 8-week Tai Chi Chih exercise program on physical functional performance (PFP) among women aged 45 to 65 years. A quasi-experimental design with a nonequivalent comparison group was used. Forty-one healthy inactive women were assigned to either an intervention group (n = 19) or a comparison group (n = 19). A 60-min Tai Chi Chih exercise class was conducted twice a week for 8 weeks. PFP was measured at baseline and postintervention using the Continuous Scale Physical Functional Performance-10 (CS-PFP 10). Between-group differences were analyzed using one-way analysis of covariance (ANCOVA). After participating in the 8-week program, intervention group participants showed greater improvement in the CS-PFP measures (p .06). However, the comparison group had little changes. The findings from this study suggest that participation in an 8-week Tai Chi Chih exercise program can improve PFP in healthy, community-dwelling middle-aged women. © The Author(s) 2013.

    Full Text Available Introduction: Resistin is an adipocyte-specific hormone secreted from adipose tissue which plays a significant role in the energy homeostasis and regulation of energy metabolism. The purpose of this study was to examine the effects of eight weeks of aerobic training on the resistin levels and insulin resistance in sedentary middle-aged women. Methods: In this quasi-experimental research, 20 sedentary women were randomly selected and assigned to two groups: experimental group, n=10, aged 47.70±5.35; and control, n=10, age 41.30±3.02, respectively. The participants in the training group performed an exercise protocol three times per week with the goal of 55 to 65 per cent of maximum heart rate. Before and after the completion, the resistin, insulin, glucose and insulin resistance levels were measured after 12 h of overnight fasting. Data were analyzed before and after the intervention by t-test. The significant level was defined as P≤0.05. Results: Aerobic training in compared with the control group showed significant effect in decreasing resistin levels (P=0.012, BMI (P=0.01, insulin resistance (P=0.01, and increasing VO2 max (P=0.004. Conclusion: It appears that eight weeks of aerobic training significantly changes the level of resistin and the insulin resistance index in sedentary middle-aged women. Plasma resistin may be associated with insulin resistance in sedentary women. In general, according to the results, we may say that an eight-week aerobic training with a significant reduction in plasma resistin has a preventive effect as a new and effective training method on insulin resistance in middle-aged sedentary women.

This was a retrospective cohort study from National Institute of Child Health and Human Development Neonatal Research Network's Generic Database and Follow-Up Studies. Infants born at impairment was defined as any of the following: cognitive score blindness (bilateral vision impairment. The SGA group comprised 385 infants; the non-SGA group, 2586 infants. Compared with mothers of non-SGA infants, mothers of SGA infants were more likely to have a high school education, prenatal care, cesarean delivery, pregnancy-induced hypertension, and antenatal corticosteroid exposure. Compared with non-SGA infants, SGA infants had higher mortality and were more likely to have postnatal growth failure, prolonged mechanical ventilation, and postnatal steroid use. SGA status was associated with increased risk of death or neurodevelopmental impairment (OR, 3.91; 95% CI, 2.91-5.25; P impairment at 18-22 months corrected age. Copyright © 2013.

    To examine the response of the endocrine system, strength development and muscle circumference to moderate-resistance training in younger and middle-aged men. Two groups of men of similar activity background, but differing in age (Y: 21.2±2.2years and M: 49.7±2.1years) participated in an 8-week moderate-resistance training program. Blood sampling was obtained at rest before and after training for analysis of serum testosterone, growth hormone, cortisol and ACTH concentrations. One repetition maximum for the bench press (1RM(BP)) and squat (1RM(S)); thigh (TC) and arm circumference (AC) were also measured. Both groups underwent a 1-h standardized moderate-resistance training session (three series of 8 to 15RM; nine exercises with 1-3min rest between sets) three times a week for 8weeks. Both the Y and M groups gained significant improvements in 1RM(BP), 1RM(S), TC and AC (Pstrength, muscle circumference and increases anabolic hormone secretion for M men and consequently promoting of health, improve daily life and delay negative effects with aging.

    A dose-response assay was conducted using broken-line regressions to estimate the lysine (Lys) requirements of quail chicks from 21 to 35 d of age. A basal diet was formulated to be adequate in all nutrients other than Lys. Incremental levels of L-Lys.HCl were added to the basal diet at the expense of a mix of cornstarch, NaHCO3, and NaCl to create 6 experimental diets containing 0.84 to 1.59% Lys. Feed intake (FI), weight gain (WG), and feed conversion ratio (FCR) responded quadratically to incremental levels of Lys (P Japanese quail at the late stage of production might be 1.36% of diet, which is 105% of NRC recommendations. © 2015 Poultry Science Association Inc.

    Full Text Available Introduction: Over the last decades, survival of extremely preterm infants improved but there´s still significant morbidity among this group. We pretend to evaluate if specific attitudes/characteristics are associated with higher survival or survival without severe disabilities and elaborate predicting outcome models. Material and Methods: Observational descriptive study, including the 205 liveborn/stillborn infants -gestational age 22w0d-26w6d- born at an Obstetrics Unit or transferred to a Neonatology Unit of a Level III Hospital, from January-2000 to December-2009. We collected variables related to management in the prenatal/neonatal period, neonate performances and psychomotor development(18-24 months. Significant associations between variables/outcomes were identified by chi-square test or t-test; multivariate logistic regression models were used to describe and predict mortality/morbidity. Results: Advanced Gestational Age (GA (p=0.001, antenatal corticotherapy(p=0.001, cesarean section(p=0.001, inborn delivery(p=0.021 and increased weight(p=0.001 were associated with survival. Absence of Intraventricular Hemorrhage (IVH grade 3-4(p=0.001 and absence of Periventricular Leukomalacia (PVL (p=0.005 were associated with survival without severe neurossensorial deficit. According to multivariable models, advanced GA (OR=0.353,CI95% 0.208-0.599, increased weight (OR=0.996,CI95% 0.993-0.999 and antenatal corticotherapy (OR=0.150,CI95% 0.044-0.510 were associated with lower mortality risk. Rupture of membranes less than 12 h duration was associated with higher mortality risk (OR=3.88,CI95% 1.406-10.680. IVH grades 3-4 was associated with higher morbidity risk (OR=16.931,CI95% 2.744-104.452. Mortality and severe morbidity models predicted correctly the outcome in 78.1% and 85.7% of the cases, respectively. Conclusions: Mortality/morbidity models might be valuable tools providing insight in the prediction of the outcome of these neonates and helping

    Full Text Available An experiment was conducted to assess the optimal levels of dietary lysine (Lys in Japanese quail from 7 to 21 days of age. A dose-response diet was formulated to be adequate in all amino acid concentrations with the exception of Lys. Different levels of supplemental L-Lysine.HCl were added to the dose-response diet at the expense of corn starch, sodium bicarbonate, and NaCl to create 6 levels of Lys ranged from 0.91% to 1.51% in diet. Optimal Lys for feed conversion ratio, breast meat yield, and leg meat yield were estimated at 1.15%, 1.21%, and 1.16% of diet, respectively, based on linear broken-line regression. With quadratic broken-line regression, the Lys requirements for body weight gain, feed conversion ratio, thigh meat yield, and breast meat yield were estimated at 1.27%, 1.21%, 1.32%, and 1.34% of diet, respectively. Overall, Lys requirements of starting Japanese quail may be at least 1.34% of diet for optimizing carcass attributes fed low-CP dose-response diet.

    Full Text Available Regular moderate physical activity positively affects health, fitness, and body composition; it regulates the pro- and anti-inflammatory cytokines levels. Vitamin D plays an important regulatory role; its adequate levels correlate with low values of inflammation markers and an increase in muscle strength and fitness in exercising people. The study’s aim was to evaluate changes in somatic variables, oxidative stress, and inflammation markers, as well as blood calcidiol concentration in middle-aged healthy women after 12 weeks of aerobics classes—endurance exercises, including choreographic sequences, aiming to improve fitness and motor coordination. The training led to a significant reduction of body mass and fat tissue; it induced an increase in lean body mass. After the 12-week training program, plasma antioxidant status increased (0.65 ± 0.21, p<0.01 and the concentration of lipid peroxidation products decreased (0.07 ± 0.02, p<0.001. A significant increase in plasma antioxidant status associated with training could have reduced the level of proinflammatory interleukin as indicated by a positive correlation between these variables (rs = 0.64, p<0.05. The study proved that a 12-week health training program in physically inactive middle-aged women might provide improvements in their anthropometric parameters and selected biochemical indicators.

    Full Text Available Visfatin is a highly expressed protein with insulin-like functions located predominantly in visceral adipose tissue and has been linked to obesity and increased health risks. The purpose of this study was to examine the effects of 12 weeks of combined exercise training on visfatin and metabolic syndrome factors in obese middle-aged women. Subjects were randomly assigned to either a training (n = 10 or control (n = 10 group. The training group exercised for 1 hour, 3 days per week during the 12 week supervised training program. The training program included 3 sets of 10 repetition maximum (10RM resistance exercise as well as aerobic exercise at an intensity of 60-70% of their heart rate reserve (HRR. The control group was asked to maintain their normal daily activities. Two-way (group X time repeated measured analysis of variance revealed no significant main effects, but there was a significant group X time interaction for the following variables: body weight (p < 0.01, percent body fat (% fat (p < 0.01, waist hip ratio (WHR (p < 0.01, diastolic blood pressure (DBP (p < 0.05, fasting glucose level (p < 0.01, triglyceride levels (TG (p < 0.01, high density lipoprotein cholesterol levels (HDL-C (p < 0.05, and visfatin (p < 0.01. In conclusion, the 12 week combined resistance and aerobic training program used in this study was very effective for producing significant benefits to body composition and metabolic syndrome factors, as well as lowering visfatin levels in these obese middle-aged women.

    Introduction Extremely low gestational age newborns (ELGANs) are at increased risk of chronic lung disease (CLD) and of developmental delay. Some studies have suggested that CLD contributes to developmental delay. Patients and Methods We examined data collected prospectively on 915 infants born before the 28th week of gestation in 2002–2004 who were assessed at 24 months of age with the Bayley Scales of Infant Development-2nd Edition or the Vineland Adaptive Behavior Scales. We excluded infants who were not able to walk independently (Gross Motor Function Classification System score mechanical ventilation (MV) (CLD without MV) or receiving MV (CLD with MV). Results Forty-nine percent of ELGANs had CLD; of these, 14% were receiving MV at 36 weeks' postmenstrual age. ELGANs without CLD had the lowest risk of a Mental Developmental Index (MDI) or a Psychomotor Developmental Index (PDI) of <55, followed by ELGANs with CLD not receiving MV, and ELGANs with CLD receiving MV (9%, 12%, and 18% for the MDI and 7%, 10%, and 20% for the PDI, respectively). In time-oriented multivariate models, the risk of an MDI of <55 was associated with the following variables: gestational age of <25 weeks; single mother; late bacteremia; pneumothorax; and necrotizing enterocolitis. The risk of a PDI of <55 was associated with variables such as single mother, a complete course of antenatal corticosteroids, early and persistent pulmonary dysfunction, pulmonary deterioration during the second postnatal week, pneumothorax, and pulmonary interstitial emphysema. CLD, without or with MV, was not associated with the risk of either a low MDI or a low PDI. However, CLD with MV approached, but did not achieve, nominal statistical significance (odds ratio: 1.9 [95% confidence interval: 0.97–3.9]) for the association with a PDI of <55. Conclusions Among children without severe gross motor delays, risk factors for CLD account for the association between CLD and developmental delay. Once those

    Heredity as well as external factors influences the development of allergic rhinitis. The aim of this study was to analyse early risk factors and protective factors for allergic rhinitis at school age. This is a prospective, longitudinal study of children born in western Sweden in 2003 where 50% of the birth cohort was randomly selected. The parents answered questionnaires at 6 months, 12 months, 4.5 yr and 8 yr. At 8 yr, 5044 questionnaires were distributed. Of these, 4051 responded, that is, 80.3%. Current allergic rhinitis was defined as symptoms and use of medication during the past 12 months. Current allergic rhinitis at 8 yr was reported by 10.9%. Mean onset age was 5.7 yr, and 61.9% were boys. In a multivariate analysis, antibiotics in the first week of life increased the risk of allergic rhinitis (adjusted odds ratio 1.75, 95% confidence interval (1.03, 2.97)). Increased risk was also seen with parental allergic rhinitis (aOR 2.73 (2.12, 3.52)), food allergy first year (aOR 2.45 (1.61, 3.73)), eczema first year (aOR 1.97 (1.50, 2.59)) and male gender (aOR 1.35 (1.05, 1.74)). Living on a farm at 4.5 yr reduced the risk (aOR 0.31 (0.13, 0.78)). Antibiotics in the first week of life increased the risk of allergic rhinitis at school age, while living on a farm at preschool age reduced the risk. Both findings are compatible with the hygiene hypothesis. © 2014 The Authors. Pediatric Allergy and Immunology Published by John Wiley & Sons Ltd.

    Preterm infants undergo frequent painful procedures in the neonatal intensive care unit. Electroencephalography (EEG) changes in reaction to invasive procedures have been reported in preterm and full-term neonates. Frontal EEG asymmetry as an index of emotion during tactile stimulation shows inconsistent findings in full-term infants, and has not been examined in the context of pain in preterm infants. Our aim was to examine whether heel lance for blood collection induces changes in right-left frontal asymmetry, suggesting negative emotional response, in preterm neonates at different gestational age (GA) at birth and different duration of stay in the neonatal intensive care unit. Three groups of preterm infants were compared: set 1: group 1 (n=24), born and tested at 28 weeks GA; group 2 (n=22), born at 28 weeks GA and tested at 33 weeks; set 2: group 3 (n=25), born and tested at 33 weeks GA. EEG power was calculated for 30-second artifact-free periods, in standard frequency bandwidths, in 3 phases (baseline, up to 5 min after heel lance, 10 min after heel lance). No significant differences were found in right-left frontal asymmetry, or in ipsilateral or contralateral somatosensory response, across phases. In contrast, the Behavioral Indicators of Infant Pain scores changed across phase (PPain scores (P=0.039). There are technical challenges in recording EEG during procedures, as pain induces motor movements. More research is needed to determine the most sensitive approach to measure EEG signals within the context of pain in infancy.

    Full Text Available The large utilization of coccidiostats in dairy herds has raised the question regards the best product to use, based on better animal performance. Sixty-four Holstein calves were randomly assigned to four treatments at 10 (±4 d of age to evaluate calf performance when fed approved coccidiostats available on the market in Arizona, USA. Calves received a dry calf starter without (control or with one of the following coccidiostats: lasalocid, 30 mg kg-1; decoquinate, 19 mg kg-1; and monensin, 30 mg kg-1. Calves received 3.6 kg d-1 of a commercial 22% CP:20% fat milk replacer until 6 wk of age. Calves were offered starter "ad libitum" up to 2 kg d-1, and calves had free access to water throughout the trial. Alfalfa hay was offered "ad libitum" after weaning. Performance and dry matter intake (DMI were monitored for 20 weeks and broken down in different periods of measurement (0-6, 7-12 and 13-20 weeks, respectively. Despite the lower dry matter intake and weight gain for females on monensin treatment during the whole period, differences among coccidiostats were seldom observed under the conditions of this study. Good calf management and the dry, hot climate of Arizona perhaps diminished the chances for subclinical and chronic disease appearance which negated potential differences and differences in calf performances.

    Full Text Available Abstract Background Studies comparing perinatal outcomes in multiples conceived following the use of artificial reproductive technologies (ART vs. spontaneous conception (SC have reported conflicting results in terms of mortality and morbidity. Therefore, the objective of our study was to compare composite outcome of mortality and severe neonatal morbidities amongst preterm multiple births ≤ 32 weeks gestation infant born following ART vs. SC. Methods We conducted a single center cohort study at Mount Sinai Hospital, Toronto, Ontario, Canada. Data on all preterm multiple births (≤ 32 weeks GA discharged between July 2005 and June 2008 were retrospectively collected from a prospective database at our centre. Details regarding mode of conception were collected retrospectively from maternal health records. Preterm multiple births were categorized into those born following ART vs. SC. Composite outcome was defined as combination of death or any of the three neonatal morbidities (grade 3/4 intraventricular hemorrhage or periventricular leukomalacia; retinopathy of prematurity > stage 2 or chronic lung disease. Univariate and multivariate regression analysis were preformed after adjustment of confounders (maternal age, parity, triplets, gestational age, sex, and small for gestational age. Results One hundred and thirty seven neonates were born following use of ART and 233 following SC. The unadjusted composite outcome rate was significantly higher in preterm multiples born following ART vs. SC [43.1% vs. 26.6%, p = 0.001; OR 1.98 (95% CI 1.13, 3.45]; however, when adjusted for confounders the difference between groups was not statistically significant [OR 1.39, 95% CI 0.67, 2.89]. Conclusion In our population of preterm multiple births, the mode of conception had no detectable effect on the adjusted composite neonatal outcome of mortality and/or three neonatal morbidities.

    Sarcopenia is the age-related loss of muscle mass and function, reducing force generation and mobility in the elderlies. Contributing factors include a severe decrease in both myofiber size and number as well as a decrease in the number of motor neurons innervating muscle fibers (mainly of fast type) which is sometimes accompanied by reinnervation of surviving slow type motor neurons (motor unit remodeling). Reduced mobility and functional limitations characterizing aging can promote a more sedentary lifestyle for older individuals, leading to a vicious circle further worsening muscle performance and the patients’ quality of life, predisposing them to an increased risk of disability, and mortality. Several longitudinal studies have shown that regular exercise may extend life expectancy and reduce morbidity in aging people. Based on these findings, the Interreg IVa project aimed to recruit sedentary seniors with a normal life style and to train them for 9 weeks with either leg press (LP) exercise or electrical stimulation (ES). Before and at the end of both training periods, all the subjects were submitted to mobility functional tests and muscle biopsies from the Vastus Lateralis muscles of both legs. No signs of muscle damage and/or of inflammation were observed in muscle biopsies after the training. Functional tests showed that both LP and ES induced improvements of force and mobility of the trained subjects. Morphometrical and immunofluorescent analyses performed on muscle biopsies showed that ES significantly increased the size of fast type muscle fibers (pimprove the functional performances of aging muscles. Here ES is demonstrated to be a safe home-based method to counteract fast type fiber atrophy, typically associated with aging skeletal muscle. PMID:26913162

In fact, adiponectin and leptin concentrations that are called adipokines are altered in obesity with a decreased production of adiponectin and an increased production of leptin. Adiponectin has anti-inflammatory, anti-atherosclerotic and anti-insulin resistance properties, but increased levels of leptin are observed in patients with diabetes and cardiovascular diseases. The aim of the present study was to investigate the effects of an 8-week aerobic training program on the plasma levels of adiponectin and leptin in healthy middle-aged men.

    Enzootic pneumonia, resulting from infection with Mycoplasma hyopneumoniae, is of considerable economic importance to the pig industry and normally is controlled through active vaccination of piglets. We have demonstrated that administration of an inactivated Mycoplasma hyopneumoniae vaccine to piglets less than 1 week old is efficacious under field conditions and reduces the level of lung lesions observed in comparison to that in control pigs. Here, the results of two separate studies, one in piglets with and the second one in piglets without maternal antibodies, conducted to satisfy the requirements of the European Pharmacopoeia (monograph no. 07/2009:2448), are reported. Piglets received either minimal titer Suvaxyn MH-One or saline at less than 1 week of age and were challenged with Mycoplasma hyopneumoniae 2 weeks later. The number of lung lesions was recorded 4 weeks after challenge, and bronchial swab and lung tissue specimens were analyzed for quantification of Mycoplasma hyopneumoniae DNA. In the presence and absence of maternal antibodies, vaccination of piglets at less than 1 week of age was efficacious, with vaccinated piglets having significantly lower percentages of lung with lesions and lower Mycoplasma hyopneumoniae counts detected in bronchial swab and lung tissue specimens at necropsy. In conclusion, the vaccination of piglets at 1 week of age with Suvaxyn MH-One is efficacious in the presence of high levels of maternal antibodies.

    Preterm infants younger than 37 weeks corrected gestational age are at increased risk for abnormal control of respiration. The infant car seat challenge has been used as a screening tool to ensure cardiorespiratory stability before discharging preterm infants from many hospitals in Canada. While it is clear that infants placed in a car seat are more likely to experience oxygen desaturation and/or bradycardia than when they are supine, neither positioning predicts an adverse neurodevelopmental outcome or mortality post-discharge. A review of the literature yielded insufficient evidence to recommend routine use of the infant car seat challenge as part of discharge planning for preterm infants. This finding has prompted a change in recommendation from a previous Canadian Paediatric Society position statement published in 2000.

    Background: Polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), and 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT) are ubiquitous compounds with carcinogenic and teratogenic properties. They are chemically very stable and lipophilic and, therefore, accumulate in our food-chain. They are prenatally transmitted from mother to foetus, and mother's milk due to its high lipid content is an elimination pathway of special importance. Therefore, breast-feeding has been held responsible for elevated concentrations of these organochlorine compounds as well as for harmful effects in children later in life. Methods: Blood samples (2.5 ml) were taken from each 10 breast-fed and bottle-fed infants at 6 weeks of age. Blood specimens were immediately centrifuged, and serum was stored in glass tubes at -20 degree sign C until analysis. Three higher chlorinated PCB congeners (IUPAC nos. 138, 153 and 180), HCB, and the organic metabolite of DDT, p,p<<-DDE, were analysed with capillary gas chromatography with electron capture detection. Reliability was tested with gas chromatography-mass spectrometry. Results: There were no differences between the study groups of breast-fed and bottle-fed infants with regard to sex distribution, gestational age, birth-weight, age of the mothers, and smoking behaviour of the parents. In contrast, serum concentrations of all organochlorine compounds were significantly higher (P<0.0001) in breast-fed than in bottle-fed infants (mean): PCB 138, 0.38 vs. 0.10 μg/l; PCB 153, 0.49 vs. 0.1 μg/l; PCB 180, 0.31 vs. 0.04 μg/l; ΣPCB, 1.19 vs. 0.29 μg/l; HCB, 0.13 vs. 0.04 μg/l; p,p<<-DDE, 1.05 vs. 0.18 μg/l. Conclusions: Breast-feeding significantly increases the pollution of our infants with different organochlorine compounds as early as at 6 weeks of age. The progress of the present study will show whether this pollution will further increase with longer duration of breast-feeding, and whether breast-feeding bears any health risks for our

    Sarcopenia is the age-related loss of muscle mass and function, reducing force generation and mobility in the elderlies. Contributing factors include a severe decrease in both myofiber size and number as well as a decrease in the number of motor neurons innervating muscle fibers (mainly of fast type) which is sometimes accompanied by reinnervation of surviving slow type motor neurons (motor unit remodeling). Reduced mobility and functional limitations characterizing aging can promote a more sedentary lifestyle for older individuals, leading to a vicious circle further worsening muscle performance and the patients' quality of life, predisposing them to an increased risk of disability, and mortality. Several longitudinal studies have shown that regular exercise may extend life expectancy and reduce morbidity in aging people. Based on these findings, the Interreg IVa project aimed to recruit sedentary seniors with a normal life style and to train them for 9 weeks with either leg press (LP) exercise or electrical stimulation (ES). Before and at the end of both training periods, all the subjects were submitted to mobility functional tests and muscle biopsies from the Vastus Lateralis muscles of both legs. No signs of muscle damage and/or of inflammation were observed in muscle biopsies after the training. Functional tests showed that both LP and ES induced improvements of force and mobility of the trained subjects. Morphometrical and immunofluorescent analyses performed on muscle biopsies showed that ES significantly increased the size of fast type muscle fibers (p<0.001), together with a significant increase in the number of Pax7 and NCAM positive satellite cells (p<0.005). A significant decrease of slow type fiber diameter was observed in both ES and LP trained subjects (p<0.001). Altogether these results demonstrate the effectiveness of physical exercise either voluntary (LP) or passive (ES) to improve the functional performances of aging muscles. Here ES is

    Full Text Available Introduction: Frailty syndrome and advanced age may decrease the acceptance of illness and quality of life, and worsen patients’ existing health conditions, as well as leading to an increase in health care expenses. Purpose: The purpose of this study is to reduce frailty risk via the use of a FRED game which has been expressly designed and put together for the study. Materials and methods: A total of 40 frail volunteers with a score of <10 points in the short physical performance battery (SPPB took part in a feasibility study in order to validate the FRED game. Following randomisation, the study group (20 subjects took part in nine sessions of 20 min each over a three-week period. The control group (19 subjects continued to lead their daily lives in the course of which they had no physical activity scheduled; Results: After three weeks and having taken part in nine physical activity sessions with the FRED game, 60% of subjects from the study group (12/20 obtained a score of ≥10 points at the end of the study, i.e., less risk of evidencing frailty. This result proved to be statistically significant (p < 0.001. The degree of compliance with and adherence to the game was confirmed by 100% attendance of the sessions. Discussion: Our findings support the hypothesis that FRED, an ad hoc designed exergame, significantly reduced the presence and severity of frailty in a sample of sedentary elders, thus potentially modifying their risk profile. Conclusions: The FRED game is a tool that shows a 99% certain improvement in the degree of frailty in frail elderly subjects. The effectiveness of the design of ad hoc games in a certain pathology or population group is therefore evidenced.

    Full Text Available Introduction. Aneuploidies are the major cause of perinatal death and early psychophysical disorders. Objective. In this study, we analyzed detection and false-positive rates of screening for aneuploidies in the first trimester by the combination of maternal age, fetal nuchal translucency (NT thickness and maternal serum free beta-human chorionic gonadotrophin (β-hCG, and pregnancy-associated plasma protein-A (PAPP-A at 11-13+6 weeks of gestation, using the appropriate software developed by the Fetal Medicine Foundation. Methods. Our screening study for aneuploidies analyzed 4172 singleton pregnancies from January 2006 to December 2010. The sensitivities and false-positive rates using the combined aneuploidies determination for the risk cut-off of 1:275 were evaluated. Results. In the trisomy 21 pregnancies, the fetal NT was higher than 95th centile, in 72.8%, serum free b-hCG concentration it was above the 95th centile in 55% and serum PAPP-A was below the 5th centile in 47% of the cases. In the trisomy 18 and 13, the fetal NT was above 95th centile in 66.6% and 44.4% of the cases, respectively. The serum free b-hCG concentration was above the 95th centile in 0 and 10%, but serum PAPP-A was below 5th centile in 80.9% and 88.8% of pregnancies. In the trisomy 21 pregnancies the median free beta-hCG was 2.3 MoM and the median PAPP-A was 0.45 MoM. Chromosomal abnormalities were detected in 169 fetuses: trisomy 21 (97, Turner syndrome (19, trisomy 18 (28, trisomy 13 (11 and others (14. Detection rate of combined screening for aneuploides were 86.0% with false positive rate of 5.3% (mean age 33±4.9 years, >35 years in 35% of pregnancies. Conclusion. Our study suggests that the strategy of first-trimester combined screening of biochemical values and ultrasonographic parameters at 12 gestational weeks identifies higher percentage of aneuploidies with a lower false-positive rate than a single parameter strategy.

    Full Text Available The objective of this study was to determine the requirement of digestible methionine + cystine of brown-eggs laying hens from 50 to 66 weeks age at the end of the first production cycle. The design was completely randomized, with 150 Brown Shaver hens, which were distributed in five treatments with six replications of five birds each. Birds received a basal diet with 2857 kcal/kg metabolizable energy and 15.97% crude protein, supplemented with 0.132; 0.174, 0.215, 0.256 and 0.298% DL-methionine (98%, in order to provide 0.572, 0.613, 0.653, 0.693 and 0.734% digestible methionine + cystine. The levels of digestible methionine + digestible cystine followed, respectively, the relations of 67, 72, 77, 81 and 86% with lysine fixed at 0.851%. Feed intake, methionine + cystine intake, feed conversion per dozen eggs, egg weigth and mass, percentage of egg components, internal egg quality and weight gain were evaluated. Methionine + cystine levels showed a quadratic effect on feed conversion per dozen eggs and egg weight, a linear effect on feed conversion per kilogram of eggs and percentage of albumen. There was also a positive linear effect on yolk percentage. The methionine + cystine requirement was estimated at 0.572%, corresponding to 682 mg of digestible methionine + cystine/bird/day.

    Despite extensive research on the relationship between acute stress and hippocampal function in adults, little is known about the short- and long-term effects of prolonged juvenile stress on learning, memory, and other hippocampal functions. This experiment investigated whether spatial learning would be altered in juvenile and adult rats previously exposed to a chronic stressor: 6 h of social isolation (SI) daily at 15-21 days of age. SI was found to increase circulating plasma levels of corticosterone (CORT) and allopregnanolone (3-alpha,5-alpha-pregnan-20-one; 3,5-THP) at 1 h after separation on the fourth day, indicating that the isolation was an effective stressor. When tested as juveniles (post-natal (PN) 22-24), spatial learning was impaired on the Morris water maze in the previously isolated subjects compared to non-isolated controls. However, when tested as adults (PN 92-94), subjects previously exposed to SI during the third week of life demonstrated more rapid learning of the task than controls. These results are discussed in light of research on the effects of CORT on the developing hippocampus.

    We sought to determine perinatal outcome and maternal morbidities based on gestational age (GA) at onset of expectant management in severe preeclampsia (PE) between 27(0/7) and 33 (6/7) weeks. In this retrospective analysis of outcome in patients with severe preeclampsia, we studied 66 patients (71 fetuses) with severe PE at 27 (0)/ (7) to 33(6/ 7). All patients received corticosteroids. Perinatal and maternal complications were analyzed. Five patients had twin gestations. Median for days of prolongation was 5 days (range, 3 to 35). Birth weights of 19 (27%) were or= grade ?). Rate of abruption was significantly higher at 27 to 28 weeks as compared with > 28 weeks (25% vs 6%, p = 0.05). There was no eclampsia, and two had transient renal insufficiency at 27 weeks. Four of 11 (36%) patients with expectant management at >or= 32 weeks had pulmonary edema or hemolytic anemia, elevated liver enzymes, and low platelet count. During expectant management, rate of respiratory distress syndrome and other serious neonatal complications decrease with increasing GA, supporting a role for such management in early severe preeclampsia. Because there is significant maternal morbidity at >or= 32 weeks with minimal neonatal benefit, consideration should be given for delivery of these pregnancies following corticosteroid administration.

    The near-UV induced photoreaction of 4,5',8-trimethylpsoralen (TMP) with adenosine was investigated in a dry film state. Four major photoadducts were isolated and purified by reverse-phase liquid chromatography. The structures of the photoproducts were elucidated on the basis of spectroscopic methods, including UV, FT-IR, mass spectrometry (FAB and EI methods) and 1 H-NMR analysis. These photoproducts were characterized to be TMP-adenosine 1:1 adducts, which resulted from the covalent bond formation between the carbon C(4) of TMP and ribose 1' or 5' carbon of adenosine. Of the photoadducts, one photoadduct (V) was the major product, reflecting some selectivity in the photoreaction of TMP with adenosine in the solid state. (author)

    Enhancement of lipoprotein lipase (LPL) activity through drug administration has been shown to increase pre-heparin serum LPL concentrations; however, pre-heparin serum LPL responses to exercise training have not been determined. The present study was undertaken to investigate the effects of 12 weeks of supervised aerobic exercise training on pre-heparin serum LPL concentrations in overweight/obese men. Fifteen overweight/obese middle-aged men were assigned to one of two 12-week supervised exercise interventions: a walking group (eight participants gradually increasing brisk walking to 60 min/day 3 days a week) or a jogging group (seven participants gradually increasing jogging to 60 min/day 3 days a week). All participants maintained ad libitum diets. Blood samples were collected at baseline and immediately after 12 weeks. The primary outcome was pre-heparin serum LPL. Pre-heparin serum LPL concentrations were increased in the jogging group after 12 weeks compared with the baseline values (mean+/-SEM: 37.6+/-4.7 vs. 51.0+/-6.6 ng/mL, respectively, p= 0.033). In the walking group, pre-heparin serum LPL concentrations remained unchanged after 12 weeks. This study demonstrates that 12 weeks of jogging training increases pre-heparin serum LPL concentrations in overweight/obese middle-aged men.

The aim of this study was to investigate the effect of eight weeks aerobic training on levels of adiponectin and quality of life in middle aged women. Methods: 21 subjects with range of 50-60 year and BMI 22-25 kg/m2 were selected by convenience sampling method. Volunteers were randomly assigned into experimental (n=10 and control (n=11 groups. The eight weeks aerobic training included (3 times a week, 60 minutes per session, with intensity of 50-70 percent of reserve heart rate. Quality of life and adiponectin levels were taken at baseline and at the end of the study. Data were analyzed using paired and independent t-test for comparison of means within and between groups respectively. The level of significance was set at p<0.05. Results: Eight weeks aerobic exercise lead to the increase in adiponectin levels and subscales of quality of life such as: job, sensation, sexual scales and quality of life in inactive middle aged women (p<0.05. Significant difference was observed between active and inactive middle aged woman in weight, BMI, job, sensation and sexual scales(p<0.05. Conclusion: Eight weeks of aerobic training through improving the adiponectin levels among middle aged women can prevent the incidence of atherosclerosis diseases.

    Hip spica casting regimens for the treatment of femoral shaft fractures in a pediatric population aged 1 to 3 years vary. Patient charts were reviewed to determine if there are any clinical differences between 3 and 4 weeks in an ambulatory single-leg hip spica (SLHS) cast versus 6 to 8 weeks in a standard double-leg, non-weight-bearing hip spica cast. The medical records of 109 patients with femoral shaft fractures treated with a hip spica casting from January 1, 2008 to December 31, 2011 were examined. After exclusions, 94 patients were eligible for inclusion in the study. Patient records were assessed, noting age, weight, type of cast, time in cast, and complications. All casts were applied by senior pediatric orthopaedic surgeons at a single institution. Two groups were evaluated: 59 patients in the SLHS group and 35 in the double-leg hip spica group. The 2 groups were demographically similar with an average age of 2 years, 70.2% of patients were male, 45.7% were black, and 35.1% were white. The average time to cast removal was 4.1 weeks for the single-leg group and 5.3 weeks for the double-leg group (Pshaft fractures in patients less than 4 years old can be treated in a weight-bearing SLHS casts for approximately 4 weeks with fewer alignment and skin complications.

Thirty-one calves were weighted weekly, and the mean daily growth rate was 1.2 ± 0.03 kg from birth up to 13 weeks of age. Illness in calves and young stock was not observed. In the cows, the mean incidences of ketosis, displaced abomasum, puerperal paresis, mastitis, teat injury and retained placenta were 0, 0, 8, 22, 1 and 1%, respectively, during a 6-year period. The mean daily gain of 56 growing bulls was 1.4 kg when slaughtered at 15 months of age, which is higher than the mean daily gain of 0.95 kg in the population. Probiotics, hormones and vaccines were not used, and antibiotics were only used for treating illness. The present study indicates many advantages and few problems when dairy calves are penned together with the cows and allowed natural feeding up to 6–8 weeks of age. This production system was easy to manage, preferred by the farmer, and may satisfy the public concern regarding the practice of immediate separation of cow and calf in commercial milk production.

    Osteochondrosis (OC) is one of the main causes of leg weakness causing premature culling in breeding sows and develops in a short time frame in young growing gilts. Dietary restriction may have different effects on OC prevalence depending on the age of the gilts. The aim of this study is to investigate age-dependent effects of dietary restriction, ad libitum vs. restricted (80% of ad libitum), on the occurrence of OC in gilts at slaughter (26 wk of age). At weaning (4 wk of age), 211 gilts were subjected to one of 4 treatments of a feeding regime. Gilts were administered either ad libitum feeding from weaning until slaughter (AA); restricted feeding from weaning until slaughter (RR); ad libitum feeding from weaning until 10 wk of age, after which gilts were switched to restricted feeding (AR); or restricted feeding from weaning until 10 wk of age, after which gilts were switched to ad libitum feeding (RA). At slaughter, the elbow, hock, and knee joints were harvested. Joints were scored macroscopically for articular surface deformations indicative of OC. Gilts in the RA treatment had significantly higher odds of being affected by OC than gilts in the RR and AR treatments in the hock joint (OR=3.3, P=0.04 and OR=8.5, P=0.002, respectively) and at animal level (OR=2.5, P=0.001 and OR=1.9, P=0.01, respectively). Gilts in the AA treatment had higher odds of being affected by OC than gilts in the AR treatment in the hock joint (OR=5.3, P=0.01). The results indicate a possible pathway to reduce the prevalence of OC in breeding gilts that will have to last several parities. Switching from restricted feeding to ad libitum feeding after 10 wk of age increases OC prevalence as opposed to restricted feeding after 10 wk of age.

    In this study, scalar values for the fetal brain from 12 to 20 weeks gestational age were obtained. Fifty-two fetal specimens of 12-20 weeks gestational age with an anatomically normal and developmentally appropriate central nervous system (CNS) were scanned using a 7.0 T magnetic resonance imaging (MRI) scanner. The linear biometric measurements of the brain were then determined. All the measurements (except for the interhemispheric distance) were found to increase linearly with gestational age, although each increased at a different growth rates. The 95% confidence interval for each value was obtained. These data may be considered to be a valuable reference for the assessment of normal fetal brain development in clinical settings and as a supplement to post-mortem MRI or anatomical investigations.

    Preterm infants are recognised as developing at a significantly slower rate than their full-term peers and with different movement quality. This study aimed to describe the longitudinal gross motor trajectories of these infants in the first 18 months of (corrected) age and investigate factors associated with gross motor development. A longitudinal study was conducted with convenience samples of 58 preterm infants born Alberta Infant Motor Scale (AIMS). Forty-six preterm and 48 control infants completed all four assessments. The preterm group scored significantly lower on various sub-scores at all age levels. Almost half of the preterm infants demonstrated less progression in the sit sub-scale from 4 to 8 months (corrected) age, possibly due to an imbalance between flexor and extensor strength in the trunk. At 12 and 18 months of (corrected) age, lack of rotation and fluency in their movements were evident in some preterm infants. Presence of intra-ventricular haemorrhage and chronic lung disease were associated with poor motor performance at 4 months and use of postnatal steroids was associated with poor motor performance at 4, 8 and 18 months of corrected age. The imbalance between flexor and extensor muscle strength in preterm infants had a stronger impact on motor development than usually expected. The AIMS appears to be a sensitive assessment tool to demonstrate the unique movement characteristics in this preterm cohort. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Background Studies on exercise in knee osteoarthritis (OA have focused on elderly subjects. Subjects in this study were middle-aged with symptomatic and definite radiographic knee osteoarthritis. The aim was to test the effects of a short-term, high-intensity exercise program on self-reported pain, function and quality of life. Methods Patients aged 36–65, with OA grade III (Kellgren & Lawrence were recruited. They had been referred for radiographic examination due to knee pain and had no history of major knee injury. They were randomized to a twice weekly supervised one hour exercise intervention for six weeks, or to a non-intervention control group. Exercise was performed at ≥ 60% of maximum heart rate (HR max. The primary outcome measure was the Knee injury and Osteoarthritis Outcome Score (KOOS. Follow-up occurred at 6 weeks and 6 months. Results Sixty-one subjects (mean age 56 (SD 6, 51 % women, mean BMI 29.5 (SD 4.8 were randomly assigned to intervention (n = 30 or control group (n = 31. No significant differences in the KOOS subscales assessing pain, other symptoms, or function in daily life or in sport and recreation were seen at any time point between exercisers and controls. In the exercise group, an improvement was seen at 6 weeks in the KOOS subscale quality of life compared to the control group (mean change 4.0 vs. -0.7, p = 0.05. The difference between groups was still persistent at 6 months (p = 0.02. Conclusion A six-week high-intensive exercise program had no effect on pain or function in middle-aged patients with moderate to severe radiographic knee OA. Some effect was seen on quality of life in the exercise group compared to the control group.

    Osteochondrosis (OC) is a degenerative joint condition developing in a short time frame in young growing gilts that may cause lameness at an older age, affecting welfare and leading to premature culling of breeding sows. Causes of OC are multifactorial including both genetic and environmental factors. Floor type has been suggested to affect OC prevalence and effects might be age dependent during the rearing period. The aim of this study was to investigate possible age-dependent effects of floor type, conventional concrete partially slatted versus wood shavings as deep bedding, on OC prevalence in gilts (Dutch Large White × Dutch Landrace) at slaughter (24 wk of age; 106.5 [14.7 SD] kg of BW). At weaning (4 wk of age; 6.9 [1.3 SD] kg of BW), 212 gilts were subjected to 1 of 4 flooring regimens. Gilts were either subjected to a conventional floor from weaning until slaughter (CC), wood shavings as bedding from weaning until slaughter (WW), a conventional floor from weaning until 10 wk of age after which gilts were switched to wood shavings as bedding (CW), or wood shavings as bedding from weaning until 10 wk of age after which gilts were switched to a conventional floor (WC). After slaughter the elbow, hock, and knee joints were macroscopically examined for OC and scored on a 5 point scale where 0 indicates no OC and 4 indicates the severest form of OC. There was no significant difference (P > 0.4) between treatments on the overall OC prevalence for any joint assessed or at the animal level (all joints combined). At the animal level, however, gilts had greater odds to have OC scores 3 and 4 in the CW treatment (odds ratios [OR] = 2.3; P = 0.05), WC treatment (OR = 2.6; P = 0.02), and WW treatment (OR = 3.7; P gilts in the CC treatment. The results indicate that there are no age-dependent effects of floor types on overall OC prevalence. However, wood shavings as bedding seems to increase the odds for severe OC and might affect animal welfare in the long term.

    Even though mental disorders represent a major public health problem for women and respective children, there remains a lack of epidemiological longitudinal studies to assess the psychological status of women throughout pregnancy and later in life. This epidemiological cohort study assessed the relationship between mental disorders of 409 Brazilian women in pregnancy and 5-8 years after delivery. The women were followed from 1997 to 2000 at 17 health services, and subsequently from 2004 to 2006 at their homes. Mental disorders were investigated by the Perceived Stress Scale-PSS, General Health Questionnaire-GHQ and State-Trait Anxiety Inventories-STAI. The relationship between scores of the PSS, GHQ and STAI 5-8 years after delivery and in pregnancy was assessed by multivariate linear regression analysis, controlling for the following confounders: maternal age, education, per capita income, family size, work, marital status and body mass index. Scores of the PSS, GHQ and STAI 5-8 years after delivery were positively associated with scores of the PSS, GHQ and STAI in the three trimesters of pregnancy, and inversely associated with maternal age and per capita income (adj. R 2 varied from 0.15 to 0.37). PSS, GHQ and STAI scores in the 3rd trimester of pregnancy were positively associated with scores of the PSS, GHQ and STAI in the 1st and 2nd trimesters of pregnancy (adj. R 2 varied from 0.31 to 0.65). The results of this study reinforce the urgency to integrate mental health screening into routine primary care for pregnant and postpartum women.

    The intensity data collected by the U.S. Geological Survey (USGS) "Did You Feel It?" (DYFI) Website (USGS, DYFI; http://earthquake.usgs.gov/earthquakes/dyfi/events/se/082311a/us/index.html, last accessed Sept 2011) for the Mw5.8 Mineral, Virginia, earthquake, are unprecedented in their spatial richness and geographical extent. More than 133,000 responses were received during the first week following the earthquake. Although intensity data have traditionally been regarded as imprecise and generally suspect (e.g., Hough 2000), there is a growing appreciation for the potential utility of spatially rich, systematically determined DYFI data to address key questions in earthquake ground-motions science (Atkinson and Wald, 2007; Hauksson et al., 2008).

    Growth performance and metabolism were investigated in mink kits (n = 210) exposed to the same dietary treatment as their dams (n = 30), i.e. high (HP; 61% of metabolisable energy, ME), medium (MP; 48% of ME) or low (LP; 30% of ME) protein supply, from birth until 10 weeks of age. The kits were weighed weekly, and were measured by means of balance experiment and indirect calorimetry, in weeks eight and nine post-partum (p.p.). At weaning (seven weeks p.p.) and 10 weeks p.p. one kit per litter was killed and blood, liver and kidneys were collected. Plasma amino acid profiles, and hepatic abundance of mRNA for phosphoenolpyruvate carboxykinase (PEPCK), fructose 1,6-biphosphatase, pyruvate kinase and glucose-6-phosphatase (G-6-Pase) by q-PCR, were determined. There were no differences in live weights among kits the first four weeks of life when kits solely consumed milk, but male LP kits were the heaviest. After transition to solid feed MP kits weighed most at nine weeks of age (p < 0.05). At eight weeks of age, the kits fed the LP diet retained less (p < 0.05) N than HP and MP kits. Heat production did not differ among kits, although protein oxidation was higher (p < 0.001) in HP kits than in LP kits. Kits fed the LP diet had lower (p < 0.05) plasma concentrations of lysine, methionine and leucine than MP kits. Dietary treatment was not reflected in the relative abundance of any of the studied mRNAs, but kits had significantly lower abundance of all studied mRNA than their dams, ranging from 83% less PEPCK abundance to 40% less for G-6-Pase. The kidney mass was smallest (p < 0.01) in kits fed the LP diet, and liver masses were largest (p < 0.001) in HP kits. The results indicate that the LP diet did not meet the protein requirements for mink kits in the transition period from milk to solid feed. The capacity to regulate the rate of gluconeogenesis was even more limited in young mink kits than in adult dams. However, young mink kits can regulate protein oxidation in

    Children in Guinea-Bissau receive measles vaccine (MV) at 9 months of age, but studies have shown that an additional dose before 9 months of age might have beneficial nonspecific effects. Within a randomized trial designed to examine nonspecific effects of early MV receipt on mortality, we conducted a substudy to investigate the effect of early MV receipt on morbidity. Children were randomly assigned at a ratio of 2:1 to receive 2 doses of MV at 18 weeks and age 9 months (intervention group) or 1 dose of MV at age 9 months, in accordance with current practice (control group). Children were visited weekly from enrollment to age 9 months; the mother reported morbidity, and the field assistants examined the children. Using Cox and binomial regression models, we compared the 2 randomization groups. Among the 1592 children, early measles vaccination was not associated with a higher risk of the well-known adverse events of fever, rash, and convulsions within the first 14 days. From 15 days after randomization to age 9 months, early measles vaccination was associated with reductions in maternally reported diarrhea (hazard ratio [HR], 0.89; 95% confidence interval [CI], .82-.97), vomiting (HR, 0.86; 95% CI, .75-.98), and fever (HR, 0.93; 95% CI, .87-1.00). Early MV receipt was associated with reduced general morbidity in the following months, supporting that early MV receipt may improve the general health of children.

    Full Text Available Objective. To identify factors affecting closure of patent ductus arteriosus (PDA in newborn infants born at 22–27 weeks gestational age (GA during pharmacological treatment with cyclooxygenase inhibitors. Method. Infants born at 22–27 weeks of GA between January 2006 and December 2009 who had been treated pharmacologically for PDA were identified retrospectively. Medical records were assessed for clinical, ventilatory, and outcome parameters. Echocardiographic examinations during treatment were reviewed. Results. Fifty-six infants were included in the study. Overall success rate of ductal closure with pharmacological treatment was 52%. Infants whose PDA was successfully closed had a higher GA (25+4 weeks versus 24+3 weeks; P=0.047, and a higher pretreatment left to right maximal ductal flow velocity (1.6 m/s versus 1.1 m/s; P=0.023. Correcting for GA, preeclampsia, antenatal steroids, and age at start of treatment, a higher maximal ductal flow velocity was still associated with successful ductal closure (OR 3.04; P=0.049. Conclusion. Maximal ductal flow velocity was independently associated with success of PDA treatment.

    Ruminal cannulation techniques are frequently used to study fermentation in the ruminant forestomach. Unsatisfactory results with the traditionally applied procedure for cannulation of young calves stimulated the development of a simpler and more robust procedure; this procedure was tested for effects on performance traits and gross anatomy of the gastrointestinal tract compared with a control group not undergoing surgery. Five calves were ruminally cannulated at approximately 10 d of age and 5 matching calves were used as controls. All calves were fed milk replacer and a diet based on clover grass silage and sodium hydroxide-treated wheat. Ruminal fluid was collected from cannulated calves once weekly for 3 consecutive weeks. All calves were euthanized at 43+/-3 d of age. No apparent adverse effects of cannulation were observed. Feed intake, BW gain, and gross anatomy of the gastrointestinal tract were not affected by cannulation. Minimum ruminal pH increased with sampling week, but average ruminal pH, total volatile fatty acids concentration, and volatile fatty acids proportions were not affected by sampling week. In conclusion, the implemented surgical technique was found to have no major effect on apparent animal health and performance traits, and the cannula proved useful for multiple samplings of ruminal contents in young calves.

    Full Text Available The aim of the present research was to evaluate the effect of the origin and caponisation on selected slaughter traits and quality indicators of meat in cockerels and capons of strains N88 (New Hampshire, R55 (Rhode Island Red, S11 (Sussex, and P55 (Plymouth Rock. The slaughter yield, breast muscle weight, percentage share of muscles in total in the carcasses, and fatness in general did not differ between the cockerels and capons within the evaluated strains. The trait that mostly distinguished cockerels from capons of strain N88 was the weight of leg muscles. Similarly, the fat content of carcasses expressed with the weight and percentage share of the skin with subcutaneous fat and abdominal fat did not differ between the evaluated groups of cockerels and capons. However, the weight of the leg muscles varied depending on the origin of cockerels and capons. As for the physiochemical properties of meat as well as its chemical composition, no significant differences were recorded in 18-week-old birds. The only obvious effect of the origin and caponisation was found on varied contents of fat in breast muscles in cockerels of strains N88 and P55, and capons of strain P55.

    Offspring of mice treated with cyclophosphamide (Cy; 1, 2.5 or 5 mg/kg) during pregnancy (6-18 days of gestation) and tested for immunocompetence from 5 to 10 weeks of age were found to have defective reticuloendothelial clearance. The main effects were: (a) increased elimination half time (T 1/2) of {sup 51}Cr-labeled SRBC from circulation, (b) decreased liver uptake of {sup 51}Cr and (c) impaired ability of the spleen, mostly affecting the female pups, to compensate for decreased liver uptake. The highest dose group suffered the most pronounced effects. This group was also found to have increased IgG immunoglobulin levels at 7 weeks of age. IgG antibody production in response to specific antigenic stimulation and delayed hypersensitivity reactions to oxazolone did not appear to be affected by Cy treatment.

    The present work was conducted to examine the effects of dietary crude protein (CP) levels (18, 21 and 24%) on growth performance (Initial and final body weight, daily body weight gain, feed consumption, feed conversion and protein efficiency ratio) during 2-9 weeks of age and certain body measurements (body height, tibiotarsus length and tibiotarsus girth) at 9 weeks of age. A total of 30 African Black unsexed ostrich chicks were used in the present study in simple randomized design. The results of the present work indicated that initial and final live body weight, body weight gain, feed consumption, feed conversion of ostrich chicks were insignificantly affected by dietary protein level used. Protein efficiency ratio was high in the group of chicks fed diet contained 18% CP. Results obtained indicated that tibiotarsus girth was decreased (P≤0.01) with the increasing dietary protein level, where the highest value of tibiotarsus girth (18.38 cm) was observed in chicks fed 18% dietary protein level. Body height and tibiotarsus length were not significantly different. In conclusion, the results of the present study indicate that ostrich chicks (during 2-9 weeks of age) could grow on diets contain lower levels of CP (18%).

    The impact of graded levels of day length on turkey health and behavior was determined in hens and toms raised to 18 wk of age. Birds were allocated to one of 4 lighting treatments (trt) providing 14 (14L), 17 (17L), 20 (20L), and 23 (23L) h of day length. Two time-replicated trials were completed with each, providing 2 rooms per lighting trt and each room having 3 hen (n = 720) and 3 tom (n = 480) pens. Data collection included gait score (GS), the incidence of footpad dermatitis (FPD), breast buttons and blisters, ocular size and pressure (males only), and behavioral observations (males only). Data were analyzed using SAS 9.3 based on a completely randomized design nested within 4 lighting trt. Regression analysis established relationships between response criteria and day length. Differences were considered significant at P ≤ 0.05 and trends noted at P ≤ 0.10. Gait score, FPD, and the incidence of breast buttons and blisters were assessed on 5 birds per pen at 11 and 17 wk of age. Average GS increased linearly with day length at 11 and 17 wk for both hens and toms, but the effect was larger in toms. Day length did not affect FPD, but more lesions and severe scores were found for hens than toms. The presence of breast buttons and blisters increased linearly with day length (11 wk) with the effect on blisters predominately seen in toms. Eye weight and size increased with increasing day length at 12 and 18 wk. Ocular pressure was not affected by day length. Infrared cameras recorded tom behavior over a 24 h period, and behaviors were classified over 10-min intervals using a scan sampling technique at 11 and 17 wk. Alterations in behavioral repertoire were observed with a linear increase in inactive resting and a linear decrease in standing, walking, preening, and environmental and feather pecking behaviors with increased day length. To conclude, day length affected bird mobility and incidence of breast blisters in an age- and gender-specific manner, and time

    Clinically, preterm infants show motor delay and atypical postures compared with their peers born at term. A longitudinal cohort study was designed to describe the motor development of very preterm infants from 4 to 18 months corrected age (CA). The study was also designed to investigate how the atypical postures observed in early infancy in the preterm infants might be related to their later motor development. Here we report the findings in early motor skills from 4 to 8 months CA. Early motor skills were assessed in 62 preterm infants (32 males, 30 females, mean gestation 26.94wks, SD 1.11) and 53 term infants (32 males, 21 females, mean gestation 39.55wks, SD 1.17) using the Alberta Infant Motor Scale (AIMS). The preterm infants demonstrated different motor behaviours from their term peers, with an uneven progression of motor skills in different positions from 4 to 8 months CA. At 8 months CA, 90%of the term infants were able to sit without arm support, but only 56%of the preterm infants could maintain sitting very briefly without arm support. This uneven progression may have been due to an imbalance between the active flexor and extensor strength and hence inadequate postural control in these positions. The AIMS has also been shown to be a valid assessment tool to demonstrate unique characteristics in movement quality in the preterm population.

    Background: Wolves have been shown to be better in independent problem-solving tasks than dogs, however it is unclear whether cognitive or motivational factors underlie such differences. In a number of species problem solving has been linked to both persistence in exploration and neophobia, suggesting both these aspects may underlie dog-wolf differences in problem solving. Indeed adult wolves have been shown to be more likely to approach a novel object and more persistent in their investigation of it, but also slower in making contact with it and more fearful of it than dogs. Methods: In the current study we investigated potential differences in equally-raised dogs' and wolves' explorative and neophobic behaviors in a novel environment and with novel objects at 5, 6, and 8 weeks of age. Results: Results showed that wolves were more persistent in exploring both the environment and the objects than dogs, and this was the case at all ages. There were no differences in the frequency of fear-related behaviors and time spent in proximity to humans. Stress-related behaviors were similarly expressed at 5 and 6 weeks, although wolves showed a higher frequency of such behaviors at 8 weeks. Discussion: Overall, results with puppies confirm those with adult animals: wolves appear to be more explorative than dogs. Such motivational differences need to be taken into account when comparing dogs and wolves in cognitive tasks.

    This study compared the effects of 3 weeks of upper-body vibration training, vibration and stretching, and stretching alone on shoulder flexibility in college-aged men. Twenty-one men were randomly assigned to vibration-stretching (VS; n = 8), vibration only (VO; n = 6), or stretching only (SO; n = 7) groups that trained 3 times per week for 3 weeks. All 3 groups performed 9 total sets of 30-second stretches. The VS group performed four 30-second upper-body vibration exercises and five 30-second upper-body stretching exercises. The VO group performed nine 30-second upper-body vibration exercises. The SO group performed nine 30-second upper-body stretching exercises. Shoulder flexion (SF), shoulder extension (SE), and shoulder transverse extension (STE) were assessed by a Leighton Flexometer and back scratch tests bilaterally (BSR, BSL) were measured via tape measure. A 1-way analysis of variance (ANOVA) evaluated groups at baseline and a 2-way repeated-measures ANOVA evaluated the interventions over time. At baseline, there were no group differences in age, height, or weight. There was a significant (p alone or combined with stretching, is a viable alternative to a standard stretching routine when attempting to increase shoulder flexibility. Adding vibration training to a flexibility regimen may improve the likelihood of regularly performing flexibility sessions because of increased variety.

    Evidence on the optimal time to initiation of complementary feeding in preterm infants is scarce. We examined the effect of initiation of complementary feeding at 4 months versus 6 months of corrected age on weight for age at 12 months corrected age in preterm infants less than 34 weeks of gestation. In this open-label, randomised trial, we enrolled infants born at less than 34 weeks of gestation with no major malformation from three public health facilities in India. Eligible infants were tracked from birth and randomly assigned (1:1) at 4 months corrected age to receive complementary feeding at 4 months corrected age (4 month group), or continuation of milk feeding and initiation of complementary feeding at 6 months corrected age (6 month group), using computer generated randomisation schedule of variable block size, stratified by gestation (30 weeks or less, and 31-33 weeks). Iron supplementation was provided as standard. Participants and the implementation team could not be masked to group assignment, but outcome assessors were masked. Primary outcome was weight for age Z-score at 12 months corrected age (WAZ 12 ) based on WHO Multicentre Growth Reference Study growth standards. Analyses were by intention to treat. The trial is registered with Clinical Trials Registry of India, number CTRI/2012/11/003149. Between March 20, 2013, and April 24, 2015, 403 infants were randomly assigned: 206 to receive complementary feeding from 4 months and 197 to receive complementary feeding from 6 months. 22 infants in the 4 month group (four deaths, two withdrawals, 16 lost to follow-up) and eight infants in the 6 month group (two deaths, six lost to follow-up) were excluded from analysis of primary outcome. There was no difference in WAZ 12 between two groups: -1·6 (SD 1·2) in the 4 month group versus -1·6 (SD 1·3) in the 6 month group (mean difference 0·005, 95% CI -0·24 to 0·25; p=0·965). There were more hospital admissions in the 4 month group compared with the 6

    Cancer has emerged as a growing public health problem in many parts of the world. We describe the synthesis of a series of carbohydrate-based isoquinoline-5,8-diones through the 1,4-addition reaction between 5,8-dioxo-5,8-dihydroisoquinoline and aminocarbohydrates. Halogenated quinones were also synthesized. Their inhibitory effects on the proliferation of human cancer cell lines were studied. The most promising compound, derived from isoquinoline-5,8-dione, containing ribofuranosidyl ring, was selectively active in vitro against H1299 cancer cells, with 1.7-fold higher activity than that of vinorelbine tartrate. This result suggests that the glycoconjugate in question may constitute a valuable lead compound to design and synthesize a more active and less toxic derivative with respect to the development of a new antitumor substance.

    The aim of the research was to study the effects of an insect meal from Hermetia illucens larvae (HILM) as complete replacement of soybean meal (SBM) on productive performance and blood profiles of laying hens, from 24 to 45 wk of age. A total of 108 24-week-old Lohmann Brown Classic laying hens was equally divided into 2 groups (54 hens/group, 9 replicates of 6 hens/group). From 24 to 45 wk of age, the groups were fed 2 different isoproteic and isoenergetic diets: the control group (SBM) was fed a corn-soybean meal based diet, while in the HILM group the soybean meal was completely replaced by Hermetia illucens larvae meal. Feed intake, number of eggs produced, and egg weight were recorded weekly along the trial. At 45 wk of age, blood samples were collected from 2 hens per replicate. The use of HIML led to a more favorable (P meal produced a higher percentage of eggs from small (S), medium (M), and extra-large (XL) classes (P meal, while creatinine was higher (P meal can be a suitable alternative protein source for laying hens even if the complete replacement of soybean meal needs further investigation to avoid the negative effects on feed intake. © 2017 Poultry Science Association Inc.

    Full Text Available Background: Preterm neonates are at a high risk of respiratory depression at birth. Incidence of respiratory distress is reported in 60-80% of the neonates born with the gestational age of less than 28 weeks and 15-30% of the neonates with the gestational age of less than 32-34 weeks. The present study aimed to compare the incidence and risk of failed extubation in using caffeine and aminophylline in the preterm neonates with the gestational age of ≤30 weeks in the periextubation period.Methods: This single-centered, parallel, open-label, randomized controlled trial was conducted in a tertiary care referral hospital in India during June 2014-2016. Neonates with the gestational age of ≤30 weeks who were intubated for a minimum of 24 hours were enrolled in the study. Neonates with major anomalies, heart disease, and sepsis were excluded from the study. After the random allocation of the infants to treatment with the standard dose of caffeine citrate and aminophylline methylxanthine, intubation continued for seven consecutive days with or without non-invasive ventilatory support. As the primary objective, the incidence and risk of failed extubation were assessed. Secondary objective of the research was to compare the relative incidence of acute adverse effects, persistent apnea, and the associated morbidities.Results: Neonates treated by caffeine were at a higher risk of extubation failure (1.09 times adjusted with birth weight (31.5% versus 21.4%; RR=1.09; 95% CI: 0.81-1.46; P=0.55, which was not statistically significant. In addition, risk of apnea within seven days and after seven days of methylxanthine therapy was 1.57 (95% CI: 0.95-2.61 and 1.10 (95% CI: 0.95-2.61 times higher in the neonates with caffeine treatment. Also, rate of tachycardia was high in the neonates treated by aminophylline, which was statistically significant (RR=0.27; 95% CI: 0.13-0.56; P

    Poor physical abilities of broilers may prevent them from performing behaviours for which they are motivated. The aim of this study was to measure the influence of physical ability and motivation on the performance of broilers in short physical tasks. We tested birds from a fast- and a slow-growing broiler strain in a runway to 12 weeks of age. To manipulate motivation, half of the birds of each strain was feed deprived for 3h and the other half for 24h before testing. Each bird was tested in a control and a slalom runway test once a week. With a similar motivation, slow growers had a shorter latency to start walking and walked faster through the runway than fast growers in both tests. In fast growers walking speed decreased faster with age than in slow growers. Slow growers vocalised more in both tests. In the slalom test, 24h deprived birds vocalised more than 3h deprived birds. Although the fast and slow growers have a different genetic background, the results indicated that motivation is the dominant determinative factor for walking in birds with a low body weight, while physical ability is the dominant determinative factor for walking in birds with a high body weight.

    Developmental gradients play a central role in axial patterning in hydra. As part of the effort towards elucidating the molecular basis of these gradients as well as investigating the evolution of the mechanisms underlying axial patterning, genes encoding signaling molecules are under investigation. We report the isolation and characterization of HyBMP5-8b, a BMP5-8 orthologue, from hydra. Processes governing axial patterning are continuously active in adult hydra. Expression patterns of HyBMP5-8b in normal animals and during bud formation, hydra's asexual form of reproduction, were examined. These patterns, coupled with changes in patterns of expression in manipulated tissues during head regeneration, foot regeneration as well as under conditions that alter the positional value gradient indicate that the gene is active in two different processes. The gene plays a role in tentacle formation and in patterning the lower end of the body axis.

  4. Behavior in the elevated plus maze is differentially affected by testing conditions in rats under and over three weeks of age

    2015-02-01

    Full Text Available The late postnatal period in rats is marked by numerous changes in perceptual and cognitive abilities. As such, age-related variation in cognitive test performance might result in part from disparate sensitivities to environmental factors. To better understand how testing conditions might interact with age, we assessed anxiety behavior on an elevated plus maze in juvenile rats around three weeks of age under diverse testing conditions. Plasma corticosterone and neuronal activation patterns in the forebrain were examined after maze exposure. We found that anxiety was differentially expressed during different stages of late postnatal development. Bright illumination and morning testing encouraged greatest open arm exploration on the elevated plus maze in younger animals, while older rats explored open areas more under dim illumination in the morning compared to bright illumination in the afternoon/evening. Older rats exhibited higher plasma corticosterone levels at baseline compared to younger rats; however, this trend was reversed for post-testing corticosterone. Additionally, post-testing corticosterone levels were inversely related to time of testing. Compared to testing in the morning, elevated plus maze exposure in the afternoon/evening elicited greater neuronal Arc expression in the amygdala. Arc expression in the amygdala after morning testing was greater at P22-24 than P17-19. In layer 2/3 of primary visual cortex, Arc expression was elevated in younger animals and age interacted with time of testing to produce opposing effects at P17-19 and P22-24. These data suggest that age-related differences in anxiety-associated behavior during the late postnatal period are due in part to changes in light sensitivity and emergence of a circadian cycle for corticosterone. The findings illustrate that late postnatal behavioral development in rodents is a complex orchestration of changes in neural systems involved in perception, cognition, affect and

    A reconnaissance team documented the geotechnical and geological aspects in the epicentral region of the Mw (moment magnitude) 5.8 Mineral, Virginia (USA), earthquake of 23 August 2011. Tectonically and seismically induced ground deformations, evidence of liquefaction, rock slides, river bank slumps, ground subsidence, performance of earthen dams, damage to public infrastructure and lifelines, and other effects of the earthquake were documented. This moderate earthquake provided the rare opportunity to collect data to help assess current geoengineering practices in the region, as well as to assess seismic performance of the aging infrastructure in the region. Ground failures included two marginal liquefaction sites, a river bank slump, four minor rockfalls, and a ~4-m-wide, ~12-m-long, ~0.3-m-deep subsidence on a residential property. Damage to lifelines included subsidence of the approaches for a bridge and a water main break to a heavily corroded, 5-cm-diameter valve in Mineral, Virginia. Observed damage to dams, landfills, and public-use properties included a small, shallow slide in the temporary (“working”) clay cap of the county landfill, damage to two earthen dams (one in the epicentral region and one further away near Bedford, Virginia), and substantial structural damage to two public school buildings.

    Mollusks represent the largest lophotrochozoan phylum and exhibit highly diverse body plans. Previous studies have demonstrated that transcription factors such as Pax genes play important roles during their development. Accordingly, in ecdysozoan and vertebrate model organisms, orthologs of Pax2/5/8 are among others involved in the formation of the midbrain/hindbrain boundary, the auditory/geosensory organ systems, and the excretory system. Pax2/5/8 expression was investigated by in situ hybridization during the development of representatives of the two major molluscan subclades, Aculifera and Conchifera. Compared to the investigated polyplacophoran and bivalve species that lack larval statocysts as geosensory organs and elaborate central nervous systems (CNS), cephalopods possess highly centralized brains and statocysts. Pax2/5/8 is expressed in regions where sensory cells develop subsequently during ontogenesis. Expression domains include esthetes and the ampullary system in polyplacophorans as well as the eyes of cephalopods. No Pax2/5/8 expression was observed in the less centralized CNS of bivalve, polyplacophoran, and gastropod embryos, thus arguing for a loss of Pax2/5/8 involvement in CNS development in these lineages. In contrast, Pax2/5/8 is expressed among others in brain lobes along the trajectory of the esophagus that divides the cephalopod brain. Our results, along with those on Otx- and Hox-gene expression, demonstrate that the cephalopod condition is similar to that in mouse and fruit fly, with Otx being expressed in the anterior-most brain region (except for the vertical lobe) and a Pax2/5/8 expression domain separating the Otx-domain from a Hox-gene expressing posterior brain region.

In addition, Pax2/5/8 is expressed in multimodal sensory systems in mollusks such as the

    Statins are used to lower cholesterol in plasma and are one of the most used drugs in the world. Many statin users experience muscle pain, but the mechanisms are unknown at the moment. Many studies have hypothesized that mitochondrial function could be involved in these side effects. The aim of the study was to investigate mitochondrial function after 2 weeks of treatment with simvastatin (S; n = 10) or pravastatin (P; n = 10) in healthy middle-aged participants. Mitochondrial respiratory capacity and substrate sensitivity were measured in permeabilized muscle fibers by high-resolution respirometry. Mitochondrial content (citrate synthase (CS) activity), antioxidant content, as well as coenzyme Q 10 concentration (Q 10 ) were determined. Fasting plasma glucose and insulin concentrations were measured, and whole body maximal oxygen uptake (VO 2max ) was determined. No differences were seen in mitochondrial respiratory capacity although a tendency was observed for a reduction when complex IV respiration was analyzed in both S (229 (169; 289 (95% confidence interval)) vs. 179 (146; 211) pmol/s/mg, respectively; P = 0.062) and P (214 (143; 285) vs. 162 (104; 220) pmol/s/mg, respectively; P = 0.053) after treatment. A tendency (1.64 (1.28; 2.00) vs. 1.28 (0.99; 1.58) mM, respectively; P = 0.092) for an increased mitochondrial substrate sensitivity (complex I-linked substrate; glutamate) was seen only in S after treatment. No differences were seen in Q 10 , CS activity, or antioxidant content after treatment. Fasting glucose and insulin as well as VO 2max were not changed after treatment. Two weeks of statin (S or P) treatment have no major effect on mitochondrial function. The tendency for an increased mitochondrial substrate sensitivity after simvastatin treatment could be an early indication of the negative effects linked to statin treatment.

    Full Text Available BACKGROUND: To estimate the cost and cost-effectiveness of a project administering de-worming and weekly iron-folic acid supplementation to control anaemia in women of reproductive age in Yen Bai province, Vietnam. METHODS AND FINDINGS: Cost effectiveness was evaluated using data on programmatic costs based on two surveys in 2006 and 2009 and impact on anaemia and iron status collected in 2006, 2007, and 2008. Data on initial costs for training and educational materials were obtained from the records of the National Institute of Malariology, Parasitology and Entomology and the Yen Bai Malaria Control Program. Structured questionnaires for health workers at district, commune and village level were used to collect ongoing distribution and monitoring costs, and for participants to collect transport and loss of earnings costs. The cost per woman treated (defined as consuming at least 75% of the recommended intake was USD0.76 per annum. This estimate includes financial costs (for supplies, training, and costs of health care workers' time. Prevalence of anaemia fell from 38% at baseline, to 20% after 12 months. Thus, the cost-effectiveness of the project is assessed at USD 4.24 per anaemia case prevented per year. Based on estimated productivity gains for adult women, the benefit:cost ratio is 6.7∶1. Cost of the supplements and anthelminthics was 47% of the total, while costs of training, monitoring, and health workers' time accounted for 53%. CONCLUSION: The study shows that weekly iron-folic acid supplementation and regular de-worming is a low-cost and cost-effective intervention and would be appropriate for population-based introduction in settings with a high prevalence of anaemia and iron deficiency and low malaria infection rates.

    Key points This study aimed to provide molecular insight into the differential effects of age and physical inactivity on the regulation of substrate metabolism during moderate‐intensity exercise.Using the arteriovenous balance technique, we studied the effect of immobilization of one leg for 2 weeks on leg substrate utilization in young and older men during two‐legged dynamic knee‐extensor moderate‐intensity exercise, as well as changes in key proteins in muscle metabolism before and after exercise.Age and immobilization did not affect relative carbohydrate and fat utilization during exercise, but the older men had higher uptake of exogenous fatty acids, whereas the young men relied more on endogenous fatty acids during exercise.Using a combined whole‐leg and molecular approach, we provide evidence that both age and physical inactivity result in intramuscular lipid accumulation, but this occurs only in part through the same mechanisms. Abstract Age and inactivity have been associated with intramuscular triglyceride (IMTG) accumulation. Here, we attempt to disentangle these factors by studying the effect of 2 weeks of unilateral leg immobilization on substrate utilization across the legs during moderate‐intensity exercise in young (n = 17; 23 ± 1 years old) and older men (n = 15; 68 ± 1 years old), while the contralateral leg served as the control. After immobilization, the participants performed two‐legged isolated knee‐extensor exercise at 20 ± 1 W (∼50% maximal work capacity) for 45 min with catheters inserted in the brachial artery and both femoral veins. Biopsy samples obtained from vastus lateralis muscles of both legs before and after exercise were used for analysis of substrates, protein content and enzyme activities. During exercise, leg substrate utilization (respiratory quotient) did not differ between groups or legs. Leg fatty acid uptake was greater in older than in young men, and although young men demonstrated net

    Full Text Available In this study, a classic survey adjustment computation method was used for data obtained in the Inner Mongolia and Ningxia gravimetric networks between September 2013 and April 2015 so as to investigate the variation of gravity before the Alxa Zuoqi M5.8 earthquake. The relationship between gravity variation and the Alxa Zuoqi M5.8 earthquake was analyzed. The results showed that: (1 the severe variation in gravity field at the test sites before the Alxa Zuoqi M5.8 earthquake, as well as the subsequent accelerated rising, might be an earthquake precursor; (2 the Alxa Zuoqi M5.8 earthquake occurred at the turning point where the high-gravity gradient zone changed from the NE direction to NW.

    Corn with naturally occurring aflatoxin (AF), wheat with naturally occurring doxynivalenol (DON), and barley with naturally occurring zearalenone (ZEA) were used to make rations for feeding turkey hen poults to 6 weeks of age. Control rations with equal amounts of corn, wheat, and barley were also fed. The control rations did contain some DON while both sets of rations contained ZEA. Within each grain source, there were 4 treatments: the control ration plus 3 rations each with a different feed additive which were evaluated for the potential to lessen potential mycotoxin effects on bird performance and physiology. The additives were Biomin BioFix (2 lb/ton), Kemin Kallsil (4 lb/ton), and Nutriad UNIKE (3 lb/ton). The mycotoxin rations reduced poult body weight (2.31 vs. 2.08 ± 0.02 kg) and increased (worsened) poult feed conversion (1.47 vs. 1.51 ± 0.01) at 6 wk. Feeding the poults the mycotoxin feed also resulted in organ and physiological changes typical of feeding dietary aflatoxin although a combined effect of AF, DON, and ZEA which cannot be dismissed. The feed additives resulted in improved feed conversion to 6 wk in both grain treatment groups. The observed physiological effect of feeding the additives was to reduce relative gizzard weight for both groups and to lessen the increase in relative kidney weight for the birds fed the mycotoxin feed. In conclusion, the feed additives used in this study did alleviate the effect of dietary mycotoxins to some degree, especially with respect to feed conversion. Further studies of longer duration are warranted. © 2017 Poultry Science Association Inc.

    Leaves of Phyllanthus acidus (PA) have been used in Thai traditional medicine for the treatment of hypertension. We have previously shown that chronic treatment of a PA water extract to middle-aged male rats caused a lowering of the body and serum lipids, two of the parameters that are implicated in cardiovascular disease. To investigate if chronic treatment of middle-aged male rats with a PA water extract affected the perivascular (aortic) adipose tissue (PVAT) and/or their vascular functions Fresh leaves of PA were extracted with water and orally gavaged to the middle-aged male rats for 6 weeks. Vascular functions were studied in vitro using isolated thoracic aorta with and without PVAT, and mesenteric rings in Krebs Heinseleit solution with results recorded with a Polygraph or a Myograph system. The amount of blood vessel eNOS and CSE (cystathionine-γ-lyase) expression was measured by Western blotting. PA treatment caused a lower maximal contractile response to phenylephrine (Phe) of the endothelium-intact aortic ring than that of the control group. This effect was abolished by N(G)-nitro-l-arginine (l-NA) or by denudation of the endothelium. dl-propargylglycine (PAG, H2S inhibitor) and TEA (Ca(2+)-activated K(+) channel blocker), but not glybenclamide (ATP-activated K(+) channel blocker), caused a similar increase in the baseline of the endothelium-intact aortic ring in the presence of l-NA in both the PA-treated and control aortic rings. This effect sequentially resulted in a greater contractile response of the aortic rings of both groups to Phe. Glybenclamide also caused a similar increase in the maximal contraction of the endothelium-intact blood vessels with l-NA to both groups. PAG, TEA or glybenclamide did not modify the phenylephrine C-R curves for either group of the PVAT-endothelium-intact aortic rings preincubated with l-NA. The CSE levels of the thoracic aorta and at the PVAT were not different between the PA-treated and the control group

    We report on the use of a 5.8 GHz microwave applicator to treat choroidal melanoma (Greene) in rabbits. The physical requirements needed to treat these intraocular tumors are quite different from those encountered elsewhere in the body. From a trans-scleral approach the penetration needed is minimal (5 to 10 mm.). The fibrous sclera is the only structure between the heat source and the tumor. The sclera has a relatively low water content when compared to tumor. This fact in addition to the frequency dependent interactions of tissue and electromagnetic radiation, results in an advantage to the use of the 5.8 GHz microwave device in treating intraocular malignancies

    Ketosis is a metabolic disorder closely associated with both lipid and carbohydrate metabolism. Recent studies show that angiopoietin-like protein 3 (ANGPTL3) contributes to the development of metabolic disorder. The objective of this study was to explore the inhibitory effect of 1,3,5,8-tetrahydroxyxanthone (Xan), a naturally occurring flavonoid compound, on ketosis and the mechanisms involved in this regulation. After 4weeks, Xan (10 or 30mg/kg, intragastrically) treatment decreased plasma total ketone bodies, malondialdehyde, 8-isoprostane, triglyceride, total cholesterol levels, and hepatic ANGPTL3 expression concomitantly with increased plasma glucose concentration and adipose lipoprotein lipase (LPL) expression in ketosis murine. The present results suggest that Xan regulates ANGPTL3-LPL pathway to lessen the ketosis in mice. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available ABSTRACT An experiment was conducted to determine the effect of varying dietary supplemental inclusion levels of onion and garlic mixture on semen quality characteristics of Koekoek breeder cocks aged 35-41 weeks. The experimental diets were isocaloric and isonitrogenous but with different supplemental inclusion levels of onion and garlic. A complete randomized design was used for the experiment. The three dietary supplemental levels based on garlic and onion supplemental inclusion levels were Q0 (0 g onion and 0 g garlic per 600 g DM feed, Q1 (2.5 g onion and 2.5 g garlic per 600 g DM feed, and Q2 (5 g onion and 5 g garlic per 600 g DM feed with each treatment having three replicates. A quadratic type equation was used to determine the onion and garlic levels for optimum semen quality characteristics. Daily supplementation with 5 g onion and 5 g garlic per 600 g DM feed increased progressive motile cells (%, actual life sperm count (×106/nl, and live sperm (% by 221.20%, 301.51%, and 352.43%, while 2.5 g onion and 2.5 g garlic per 600 g DM feed reduced them by 28.67%, 12.69%, and 19.00%, respectively. However, daily supplementation with 2.5 g onion and 2.5 g garlic per 600 g DM feed increased sperm count (×106/nl by 12.82%, whereas daily supplementation with 5 g onion and 5 g garlic per 600 g DM feed reduced it by 10.26% in Koekoek breeder cocks. Dietary onion and garlic supplemental inclusion levels of 3.009, 3.191, 4.621, 6.601, 6.719, 2.327, 2.385, and 2.247 g per 600 g DM feed supported optimum progressive motile cells (%, immotile sperm cells (%, actual dead sperm count (×106/nl, actual live sperm count (×106/nl, live sperm (%, acrosome morphology defects (%, acrosome detachment (%, and acrosome swelling (%, with probability values ranging from 0.003 to 0.783, whereas minimum progressive motile cells (% increase was achieved at an optimum onion and garlic supplementation levels of 3.009 g per 600 g DM feed.

    OBJECTIVES: The study sought to test the hypothesis that genetic variation in ABCG5/8, the transporter responsible for intestinal and hepatobiliary cholesterol efflux, may simultaneously influence plasma and biliary cholesterol levels, and hence risk of myocardial infarction (MI) and gallstone...... disease in opposite directions. BACKGROUND: High plasma levels of low-density lipoprotein (LDL) cholesterol are a causal risk factor for MI, whereas high levels of biliary cholesterol promote gallstone formation. METHODS: A total of 60,239 subjects from Copenhagen were included, including 5,647 with MI...... and 3,174 with symptomatic gallstone disease. Subjects were genotyped for 6 common, nonsynonymous and functional variants in ABCG5/8, and a combined weighted genotype score was calculated. RESULTS: Combined, weighted genotype scores were associated with stepwise decreases in LDL cholesterol of up to 5...

    Background. IMPAACT P1066 is a phase I/II open-label multicenter trial to evaluate pharmacokinetics, safety, tolerability, and efficacy of multiple raltegravir formulations in human immunodeficiency virus (HIV)–infected youth. Methods. Dose selection for each cohort (I: 12 to <19 years; II: 6 to <12 years; and III: 2 to <6 years) was based on review of short-term safety (4 weeks) and intensive pharmacokinetic evaluation. Safety data through weeks 24 and 48, and grade ≥3 or serious adverse events (AEs) were assessed. The primary virologic endpoint was achieving HIV RNA <400 copies/mL or ≥1 log10 reduction between baseline and week 24. Results. The targeted pharmacokinetic parameters (AUC0-12h and C12h) were achieved for each cohort, allowing dose selection for 2 formulations. Of 96 final dose subjects, there were 15 subjects with grade 3 or higher clinical AEs (1 subject with drug-related [DR] psychomotor hyperactivity and insomnia); 16 subjects with grade 3 or higher laboratory AEs (1 with DR transaminase elevation); 14 subjects with serious clinical AEs (1 with DR rash); and 1 subjects with serious laboratory AEs (1 with DR transaminase increased). There were no discontinuations due to AEs and no DR deaths. Favorable virologic responses at week 48 were observed in 79.1% of patients, with a mean CD4 increase of 156 cells/µL (4.6%). Conclusions. Raltegravir as a film-coated tablet 400 mg twice daily (6 to <19 years, and ≥25 kg) and chewable tablet 6 mg/kg (maximum dose 300 mg) twice daily (2 to <12 years) was well tolerated and showed favorable virologic and immunologic responses.

    1990-04-15

    The dark and photoreactions of 4'-aminomethyl-4,5',8-trimethylpsoralen (AMT) with T7 phage were investigated from biological and structural points of view. The dark reaction leads to the structural destabilization of the double helix of the DNA as is shown by optical melting measurements. The genotoxicity of AMT in the dark is comparable with that of known genotoxic drugs as determined by phage inactivation. The photoreaction with UVA light leads to the formation of mono- and di-adducts depending on the wavelength and dose used. Mono- and di-adducts influence DNA stability differently; biologically both types of adducts are genotoxic as measured by action spectra.

    We present low-temperature thermal expansion measurements on the heavy fermion system CeCu 5.8 Ag 0.2 , which is located at an antiferromagnetic (AF) quantum critical point (QCP). At zero magnetic field, the volume expansion coefficient divided by temperature shows a logarithmic divergence upon cooling below 1K. This temperature dependence is incompatible with the predictions of the itinerant spin-density wave theory for an AF QCP. The application of magnetic fields leads to a cross-over to Landau Fermi liquid behavior as expected for a zero-field QCP

    Full Text Available The association of 5',8-cyclo-2'-deoxyguanosine (cdG, a DNA tandem lesion, with its complementary base cytosine has been studied by voltammetry and NMR in chloroform, using properly silylated derivatives of the two nucleobases for increasing their solubilities. Both voltammetric data and NMR titrations indicated that the Watson-Crick complex of cytidine with cdG is weaker than that with guanosine, the difference being approximately of one order of magnitude between the two association constants.

    Full Text Available Introduction: The evidence has shown that expansion of cardiovascular disease has inflammation base, and general inflammation (systemic plays a pivotal role in the development of atherosclerosis. The purpose of this research was evaluation of changes in intercellular adhesion molecule – 1, vascular adhesion molecule-1 and C – reactive protein in middle-aged men with heart failure after eight weeks of aerobic exercise. Methods: Twenty four middle-aged men with heart failure were selected as volunteers, and were divided into two groups; the aerobic training and the control groups. Aerobic training program was eight weeks, three times per week with the intensity of 40%-70% maximum heart rate. Fasting blood samples were taken from all subjects before and after eight weeks of aerobic exercise. . Data were analyzed by paired sample t-test and independent sample t-test at a significance levels of P<0.05. Results: In the aerobic training group, comparison within groups showed, serum levels of ICAM-1, VCAM-1 and CRP (respectively P=0.001, P=0.001 and P=0.001 were significantly reduced. There was a significant reduction in comparison between groups only for VCAM-1 (P=0.001 and CRP (P=0.002. Conclusion: Aerobic exercise with reducing levels of inflammatory markers ICAM-1 and CRP may play an important role in the prevention and control of cardiovascular diseases in middle-aged men with heart failure.

    The development of the gastrointestinal tract in newborn calves is essential for sufficient nutrient uptake. An intensive milk feeding during the neonatal period may impair the rumen development in calves. The aim of this study was to investigate effects of milk replacer (MR) feeding in unlimited amounts for the first 5 wk of age on the gastrointestinal growth and development in preruminant calves at wk 9 of age. Twenty-eight newborn Holstein and Holstein × Charolais crossbred calves (19 male and 9 female) were fed MR ad libitum (ADLIB) or in restricted amounts (6 L per day; RES) until wk 5 of age. Thereafter, the MR intake of ADLIB was gradually reduced at wk 6 and 7, and all calves received 6 L of MR per day until wk 9 of age. In wk 9, calves were slaughtered and carcass and organ weight as well as rumen papilla size in the atrium, ventral sac, and ventral blind sac, and villus size of the mucosa in the small intestine (duodenum; proximal, mid, and distal jejunum; and ileum) were determined. The expression of mRNA associated with the local insulin-like growth factor (IGF) system was measured in the rumen epithelium. Ad libitum MR feeding increased MR intake and growth in ADLIB without influencing concentrate intake compared with RES. Carcass weight in wk 9 was greater in ADLIB than in RES. The density of the rumen papillae in the atrium and ventral blind sac was greater in RES than in ADLIB calves, but surface area of the epithelium was not different between groups in the investigated regions of the rumen. The mRNA abundance of IGF1 in the atrium tended to be greater and the IGFR1 mRNA abundance in the ventral sac tended to be lower in the ADLIB than in the RES feeding group. The rumen pH and volatile fatty acid concentrations were not affected by MR feeding intensity. In mid-jejunum, villus circumference was greater in ADLIB than in RES calves. In the distal jejunum, villus surface area and the villus height/crypt depth ratio were greater and the villus

    To determine whether breech presentation is an independent risk factor for neonatal morbidity, mortality, or long-term neurologic morbidity in very preterm infants. Prospective population-based cohort. Singletons infants without congenital malformations born from 27 to 32 completed weeks of gestation enrolled in France in 1997 in the EPIPAGE cohort. The neonatal and long-term follow-up outcomes of preterm infants were compared between those in breech presentation and those in vertex presentation. The relation of fetal presentation with neonatal mortality and neurodevelopmental outcomes was assessed using multiple logistic regression models. Among the 1518 infants alive at onset of labor included in this analysis (351 in breech presentation), 1392 were alive at discharge. Among those eligible to follow up and alive at 8 years, follow-up data were available for 1188 children. Neonatal mortality was significantly higher among breech than vertex infants (10.8% vs. 7.5%, P = 0.05). However the differences were not significant after controlling for potential confounders. Neonatal morbidity did not differ significantly according to fetal presentation. Severe cerebral palsy was less frequent in the group born in breech compared to vertex presentation but there was no difference after adjustment. There was no difference according to fetal presentation in cognitive deficiencies/learning disabilities or overall deficiencies. Our data suggest that breech presentation is not an independent risk factor for neonatal mortality or long-term neurologic deficiencies among very preterm infants.

    Full Text Available Abstract Background TGFβ is both neuroprotective and a key immune system modulator and is likely to be an important target for future stroke therapy. The precise function of increased TGF-β1 after stroke is unknown and its pleiotropic nature means that it may convey a neuroprotective signal, orchestrate glial scarring or function as an important immune system regulator. We therefore investigated the time course and cell-specificity of TGFβ signaling after stroke, and whether its signaling pattern is altered by gender and aging. Methods We performed distal middle cerebral artery occlusion strokes on 5 and 18 month old TGFβ reporter mice to get a readout of TGFβ responses after stroke in real time. To determine which cell type is the source of increased TGFβ production after stroke, brain sections were stained with an anti-TGFβ antibody, colocalized with markers for reactive astrocytes, neurons, and activated microglia. To determine which cells are responding to TGFβ after stroke, brain sections were double-labelled with anti-pSmad2, a marker of TGFβ signaling, and markers of neurons, oligodendrocytes, endothelial cells, astrocytes and microglia. Results TGFβ signaling increased 2 fold after stroke, beginning on day 1 and peaking on day 7. This pattern of increase was preserved in old animals and absolute TGFβ signaling in the brain increased with age. Activated microglia and macrophages were the predominant source of increased TGFβ after stroke and astrocytes and activated microglia and macrophages demonstrated dramatic upregulation of TGFβ signaling after stroke. TGFβ signaling in neurons and oligodendrocytes did not undergo marked changes. Conclusions We found that TGFβ signaling increases with age and that astrocytes and activated microglia and macrophages are the main cell types that undergo increased TGFβ signaling in response to post-stroke increases in TGFβ. Therefore increased TGFβ after stroke likely regulates glial

    The aim of this study was to investigate the efficacy of feed-grade preparations of mannan oligosaccharides ( MOS: ) and oregano essential oil ( OEO: ) in forced molted or fully fed 82-week-old, laying hens. A 2 × 3 factorial experiment investigated the influence of molting vs. full feeding and dietary supplements [i.e., unsupplemented control, MOS (1 g/kg) diet, and OEO (24 mg/kg) diet] on production parameters, egg quality, serum stress indicators, blood constituents, tibial characteristics, liver antioxidant status, and cecal microflora composition. A total of 864 Single Comb White Leghorn hens were randomly assigned to 6 treatments, each with 6 replicates of 24 hens each, and studied for 25 wk. Hens were fed a molt diet containing of 50% alfalfa and 50% wheat bran ( AA+WB: ) for 12 d, then returned to the laying ration. Results indicate that molt vs. full feed impacted more on most variables measured than supplementation or supplement type. Significant (P feed conversion ratio ( FCR: ). In fully fed hens, MOS supplementation improved (P hens. Molting improved egg quality despite the significant regression in ovary and oviduct weight (P hens were significantly lower than those of fully fed counterparts; however, poor mineralization was not reflected in the bones' mechanical properties. No significant differences were observed among treatments for hematological characteristics.

    Blood lactate at birth as result of activated anaerobic glycolysis is a marker of perinatal asphyxia. To evaluate the dynamics of blood lactate, pH and base excess (BE) as a tool for assessing the severity of fetal hypoxia and predicting neonatal outcome. 79 neonates (> or = 34 gestational weeks) were included and followed up until discharge: 43 with pathologic fetal hearth rate patterns and/or 1-minute Apgar score asphyxia group"); 36 without obstetric or clinical signs of asphyxia (control group). Samples from umbilical artery (u.a.), capillary blood at 2h and 12-24 h after birth were analyzed for blood lactate, pH and BE. Lactate value (u.a.) was significantly higher (5.3 +/- 3.4 mmol/l), pH and BE were lower (7.29 +/- 0.05 and -14.1 +/- 5.9 mmol/l) in the "asphyxia group" compared to the control group (2.7 +/- 1.2 mmol/l, 7.29 +/- 0.05 and -5.9 +/- 3.3 respectively). The 2 h lactate-values increased significantly in infants with asphyxia (6,.7 +/- 4.7) compared to the controls (3.2 +/- 1.1), the 12-24 h values were reduced in the main group (4.6 +/- 1.5) and without changes in the controls (3.2 +/- 0.88). Values of pH and BE at 2 h and 12-24 h increased progressively in both groups without significant differences between them. Hypoxic-ischemic encephalopathy (HIE) stage II-III was observed in infants with u.a. pH asphyxia. Increasing lactate concentration after birth is better predictor of severe HIE.

DESIGN, SETTING, AND PARTICIPANTS A prospective, population-based follow-up study (Extremely Preterm Infants in Sweden Study [EXPRESS]) was conducted in Sweden. The population included extremely preterm infants (children (83.7%). Visual acuity, manifest strabismus, and refractive errors were evaluated. Visual impairment was identified in 3.1% of the children, and 1.0% were blind. Refractive errors, defined as myopia less than -3 diopters (D), hypermetropia greater than +3 D, astigmatism 2 D or more, and/or anisometropia 2 D or more, were found in 25.6% of the children, and 14.1% had manifest strabismus. There were significant associations between visual impairment and treated ROP (P = .02), cognitive disability (P Children who had been treated for ROP had the highest frequency (69.0%) of eye and visual abnormalities. One-third of the extremely prematurely born children in this study had some kind of eye or visual problems, such as visual impairment, strabismus, or major refractive error. Despite being born extremely preterm, the present cohort has a similar prevalence of blindness and visual impairment as in previous Swedish cohorts of children born less prematurely.

    Newborn Holstein bull calves (n = 96) were assigned randomly at birth to receive 150 g (C150) or 450 g (C450) of IgG in the first 24 h of life from a lacteal-based colostrum replacer in 2 trials. Mass of product fed was 500 and 1,500 g, respectively. Replacer was reconstituted with warm water and administered by esophageal feeder at approximately 1, 6, and 12 h of age. Thereafter, calves were fed 2 L of whole milk twice daily at approximately 0700 and 1700 h until transported to the experimental facility at 2 to 3 d of age. Calves fed C450 had greater serum total protein and IgG concentrations at 2 to 3 d of age. Failure of passive transfer of immunity (serum IgG calves fed C150 and C450, respectively. Calves (n = 48) in trial 1 were assigned randomly within colostrum group to receive 0.68 kg/d of milk replacer (MR) for 42 d, and then 0.34 kg/d for 7 d (moderate MR, MMR) or 1 kg/d of MR for 5 d, 1.36 kg/d for 37 d, and 0.68 kg/d for 7 d (high MR, HMR). Starter and water were available for ad libitum consumption. Calves fed HMR had greater average daily gain, higher average fecal scores, more days with abnormal fecal scores, and more medical days than calves fed MMR. Calves fed HMR also had lower starter intake and tended to have lower gain-to-feed ratio than calves fed MMR. Calves fed C450 and MMR began eating calf starter earlier and ate more starter than other groups from 3 wk. In trial 2, calves (n = 48) were assigned randomly within colostrum group to housing in nursery pens bedded with clean, dry straw (clean bedding) or soiled straw used in previous studies (dirty bedding). Milk replacer was fed at 0.68 kg/d for 39 d, and then 0.34 kg/d for 3 d along with free-choice texturized starter and water. Calves fed C450 had fewer days with abnormal fecal scores and days with medical treatments compared with calves fed C150. Calves housed in dirty bedding tended to grow more slowly and have lower gain-to-feed ratio than calves housed with clean bedding. Temporal

    Presented herein are the luminescence properties of several 1,4,5,8- polinahthalisoimides. The luminescence decay curves after deconvolution exhibit three decay times: τ{sub 1}, τ{sub 2}, and τ{sub 3}.The luminescence lifetimes change along with the growth of excitation energy, as well as the contribution of each luminescence decay mechanism (A{sub 1}, A{sub 2}, and A{sub 3}). The manner of change is distinct for one sample, namely, the pure E-isomer, in comparison to the others. The radiative deexcitation coupled with radiationless vibrational energy transfer to other luminescence centers, mainly other isomer units, is discussed as a possible deexcitation mechanism of fluorescence. The Kasha–Vavilov empirical rule is not fulfilled for the studied samples, as the luminescence quantum efficiency (Φ{sub F}) distinctly depends on the excitation wavelength (λ{sub exc}). The quantum yield of one sample (about 63% of Z-isomer) is quite high, at 1%. - Highlights: • The fluorescence decay curves and quantum yields of naphthalimides are presented for the first time. • Luminescence decay curves (3 compounds) and deexcitation processes are discussed. • Fluorescence quantum efficiency measurements did not confirmed Kasha-Vavilov rule. • Large Stokes shift is regard as the main cause of the characteristics of the studied samples.

    In India, 75% of children hemoglobin response with two dosages of daily (20 mg iron and 100 μg folic acid, or 40 mg iron and 200 μg folic acid) and weekly (40 mg iron and 200 μg folic acid) IFA supplementation in children of 3-5 years of age with mild or moderate anemia (hemoglobin 7-10 g/dl). Community-based cluster randomized control trial in nine adjoining Anganwadi Centers. Four hundred twenty six enrolled participants received directly supervised IFA tablet supplementation as per the above three groups. After 100 days, the number of available subjects in the NNACP daily dose (A), daily dose doubled (B) and weekly dose (C) groups were 112, 114 and 110, respectively. Hemoglobin was estimated at baseline, 50 and 100 days by the Cynmeth hemoglobin method. At 50 days, there were no differences between the three groups, but at 100 days, adjusted hemoglobin was lowered with weekly supplementation. The mean (95% confidence interval) hemoglobin (g/dl) differences were: (i) A-B: -0.05 (-0.17, 0.05), (ii) A-C: -0.38 (-0.50, -0.27) and (iii) B-C: -0.33, (-0.45, -0.21). Anemia reduction was 18.8%, 18.4% and 10.9%, respectively, in the three groups. Directly supervised IFA supplementation at the NNACP or double dose is equally efficacious but superior to weekly regimen.

    2017-05-01

    Molto si è discusso sui quattro livelli progressivi secondo i quali Varrone struttura l’etimologia in ling. 5, 8; a ogni livello è associato un diverso tipo di analisi e si applica a una diversa categoria di parole. Una formulazione criptica ed ellittica, in un passo che nel manoscritto del testo è quasi certamente corrotto, avvolgono il quarto livello in una nube di incertezza e ambiguità. Se alcuni filologi hanno difeso il mantenimento del tradito Quartus, ubi est aditus et initia regis (“Il quarto livello è dove è l’ingresso e le origini del re”, la maggior parte delle interpretazioni moderne opta piuttosto per l’emendazione di aditus in adytum (“santuario” e legge il passo come un riferimento a vari tipi di culti misterici, collocando il quarto livello etimologico in un quadro di esoterismo. Nel presente contributo, si avanza la proposta che nel passo in questione non vi sia alcuna allusione ai misteri, ma un riferimento all’episodio storico-leggendario della fondazione, da parte di Romolo, di un “santuario” sul Campidoglio, destinato all’accoglienza di supplici provenienti da ogni popolo ed estrazione sociale. Questa istituzione portò alla formazione del primo nucleo abitativo di Roma e anche, di conseguenza, del sostrato vernacolare alle origini della lingua latina; come tale, tale episodio converge con gli interessi e le idee di Varrone. L’ipotesi che il quartus gradus etymologiae alluda al santuario di Romolo può essere difesa o dando una nuova interpretazione al termine adytum, o proponendo un’emendazione testuale (aditus > asylum, che produca il testo Quartus, ubi est asylum et initia regis.

    A ML 5.8 earthquake, the largest instrumental earthquake in the Korean peninsula, occurred on 12 September 2016 in the Gyeongju-city, SE Korea, where is regarded as a stable intraplate region. The earthquake was widely felt in the southern peninsula and had a maximum MMI VIII in the epicentral region. Most of the intraplate earthquakes occur along preexisting weaknesses, but the potentially seismogenic structures are mostly not exposed at the surface. This study focuses on (1) the structural features in the neighboring area of the epicenter, (2) the distribution of earthquake hypocenter locations during the first 10 days of the aftershock sequence of the Gyeongju earthquake, and (3) the focal mechanism solution of select events to reveal the geometry and kinematics of its causative fault. The earthquake hypocenters in plan view clearly show a linear distribution of N 28°E, which extends about 7 km southwestward from the Yangsan Fault to the Deokcheon Fault. In cross-sectional views along N28°E and perpendicularly, the hypocenters at depths between 11 and 16 km clearly delineate a subsurface fault which has a rupturing size of about 3 ´ 3 km2 and a dip of 78°SE. Based on focal mechanism solutions, the fault acted as dextral strike-slip fault under ENE-WSW compressional stress that has been widely known as the major component of current stress field in and around Korean peninsula. The general trend, N 28°E, of the seismogenic fault slightly differs from the strike of the adjacent NNE-striking Yangsan Fault with an angular difference of 15°. The Yangsan fault is the most prominent dextral strike-slip fault in SE Korea, which can be traced for 170 km with a right-lateral offset of 30 km. The strike-slip movement is well-reported to have occurred during the Paleogene. At that time, probably numerous subsidiary fractures, such as Y-, R-, R'-, and T fractures, in various directions were produced along the Yangsan master fault. It is thus interpreted that a large R

    Full Text Available The objective of this study was to evaluate the influence of a 15-month program based on aerobic, stretching, and localized exercises at different weekly amounts on the fle­xibility of middle-aged women. The study included 107 women randomly divided into three groups: Group 1 (n = 36, G1: 50.8 ± 12.5 years trained three times a week; Group 2 (n = 36, G2: 51.0 ± 14.0 years trained twice a week; and the control group (CG: n = 35, 52.1 ± 13.4 years did not practice any exercise. During 15 months, G1 and G2 underwent a training program including aerobic, stretching, and localized exercises for 60 minutes. Participants were assessed every three months to check their progression. We found that both G1 and G2 showed improvement in flexibility (sit and reach test. However, from assessment “1” to post-test, G1 showed better results (20.16 ± 8.06; 23.61 ± 7.75; 25.22 ± 7.19; 26.76 ± 7.37; 27.71 ± 7.24; 29.47 ± 7.13 compared with G2 (17.69 ± 10.06; 18.58 ± 9.19; 19.44 ± 8.94; 20.67 ± 8.20; 21.17 ± 8.26; 23.17 ± 8.35. We concluded that practicing combined physical exercises two or three times a week tend to improve the levels of flexibility and that more satisfactory values are achieved when the amount of training is larger.

    To study the long-term development (104 weeks) of insulin antibodies during treatment with insulin detemir (IDet) and insulin aspart (IAsp) in children with type 1 diabetes aged 2-16 years. A 52-week, two-arm, randomized trial comparing IDet and neutral protamine Hagedorn insulin, both in combination with IAsp, was followed by a one-arm, 52-week extension trial of the IDet + IAsp arm. The present analysis was conducted in children who completed the randomized trial and entered into the extension trial. Of the 177 children randomized to IDet treatment, 146 entered the extension trial. IDet-IAsp cross-reacting antibodies peaked within the first 39 weeks of treatment before gradually declining. A similar pattern was seen for IDet-specific and IAsp-specific antibodies. At end of trial (EOT), no correlation was observed between the level of IDet-specific or IAsp-specific antibodies or IDet-IAsp cross-reacting antibodies and either glycated hemoglobin (HbA1c) or basal insulin dose. Mean HbA1c was stable during the treatment period, with a slight increase over time from 8.41% (68.4 mmol/mol) at baseline to 8.74% (72 mmol/mol) at EOT. Mean IDet dose increased from 0.43 U/kg at baseline to 0.66 U/kg at EOT. Mean IAsp dose increased from 0.46 U/kg to 0.51 U/kg at EOT. Although treatment with IDet and IAsp is associated with development of specific and cross-reacting antibodies, no correlation between insulin antibodies and basal insulin dose or HbA1c was found.

    Our aim was to determine whether 12 weeks' aerobic Nordic walking (NW) or resistance exercise training (RT) without diet-induced weight loss could decrease oxidative stress and atherogenic index of plasma (AIP), prevalence of metabolic syndrome (MetS) and MetS score in middle-aged men with impaired glucose regulation (IGR) (n=144. 54.5 ± 6.5 years). In addition, we compared effects of intervention between overweight and obese subgroups. Prevalence of MetS and AIP index decreased only in NW group and MetS score in both NW and RT groups but not in control group. The changes in AIP index correlated inversely with changes in plasma antioxidant capacity. The change in AIP index remained a significant independent predictor of the changes in MetS score after the model was adjusted for age, BMI and volume of exercise (MET h/week) in NW group. There were no changes in the other measured markers of oxidative stress and related cytokines (e.g. osteopontin and osteoprotegerin) in any of the groups. Nordic walking decreased prevalence of MetS and MetS score. Improved lipid profile remained a predictor of decreased MetS score only in NW group and it seems that Nordic walking has more beneficial effects on cardiovascular disease risks than RT training.

    To assess effects of foods fortified with docosahexaenoic acid (DHA)-rich fish oil on cognitive, memory, psychomotor, immunologic, and retinal function and other measures of development in healthy puppies. Evaluation study. 48 Beagle puppies. Puppies were assigned to 3 groups after weaning (n = 16/group) and received 1 of 3 foods (low-DHA, moderate-DHA, or high-DHA food) as their sole source of nutrition until 1 year of age. Visual discrimination learning and memory tasks, psychomotor performance tasks, and physiologic tests including blood and serum analysis, electroretinography, and dual-energy x-ray absorptiometry were performed at various time points. Anti-rabies virus antibody titers were evaluated 1, 2, 4, and 8 weeks after vaccination at 16 weeks of age. Foods had similar proximate analysis results but varied in concentration of DHA from fish oil; the high-DHA food also contained higher concentrations of vitamin E, taurine, choline, and l-carnitine than did other foods. The high-DHA group had significantly better results for reversal task learning, visual contrast discrimination, and early psychomotor performance in side-to-side navigation through an obstacle-containing maze than did the moderate-DHA and low-DHA groups. The high-DHA group had significantly higher anti-rabies antibody titers 1 and 2 weeks after vaccination than did other groups. Peak b-wave amplitudes during scotopic electroretinography were positively correlated with serum DHA concentrations at all evaluated time points. Dietary fortification with fish oils rich in DHA and possibly other nutrients implicated in neurocognitive development following weaning improved cognitive, memory, psychomotor, immunologic, and retinal functions in growing dogs.

    UNICEF/WHO recommends that infants born to HIV-infected mothers who do not have access to acceptable, feasible, affordable, sustainable, and safe replacement feeding should be exclusively breastfed for at least 6 months. The aim of three trials in Ethiopia, India, and Uganda was to assess whether daily nevirapine given to breastfed infants through 6 weeks of age can decrease HIV transmission via breastfeeding. HIV-infected women breastfeeding their infants were eligible for participation. Participants were randomly assigned to receive either single-dose nevirapine (nevirapine 200 mg to women in labour and nevirapine 2 mg/kg to newborns after birth) or 6 week extended-dose nevirapine (nevirapine 200 mg to women in labour and nevirapine 2 mg/kg to newborn babies after birth plus nevirapine 5 mg daily from days 8-42 for the infant). The randomisation sequences were generated by computer at a central data coordinating centre. The primary endpoint was HIV infection at 6 months of age in infants who were HIV PCR negative at birth. Analyses were by modified intention to treat, excluding infants with missing specimens and those with indeterminate or confirmed HIV infection at birth. These studies are registered with ClinicalTrials.gov, numbers NCT00074399, NCT00061321, and NCT00639938. 2024 liveborn infants randomised in the study had at least one specimen tested before 6 months of age (1047 infants in the single-dose group and 977 infants in the extended-dose group). The modified intention-to-treat population included 986 infants in the single-dose group and 901 in the extended-dose group. At 6 months, 87 children in the single-dose group and 62 in the extended-dose group were infected with HIV (relative risk 0.80, 95% CI 0.58-1.10; p=0.16). At 6 weeks of age, 54 children in the single-dose group and 25 in the extended-dose group were HIV positive (0.54, 0.34-0.85; p=0.009). 393 infants in the single-dose group and 346 in the extended-dose group experienced grade 3 or 4

    Research into the language sampling practices of Australian speech pathologists suggests the Bus Story Test is a frequently used standardized tool for eliciting story retelling samples for screening, diagnosis, goal-setting, and progress monitoring purposes. Because this task has not been normed on an Australian population, this study investigated the usefulness of the Bus Story for young school-age Australian children. In total, 125 Australian primary-school children (aged 5;3-8;9) participated in the Bus Story task. Children attending Year 2 also retold the story Frog Where Are You. Children's performance was analysed for measures of information and sentence length (Bus Story only), story length, MLU, number of different words and clausal density. Performance on the Bus Story improved with year-of-schooling for all measures. Between 21-64% of the children performed below expectations on information or length scores when using the published norms. The retell task Frog Where Are You elicited longer samples, containing a higher number of different words. Using the published Bus Story norms will potentially result in over- identification of language impairment. The retell task Frog Where Are You may provide a useful alternative for assessing young school-aged children's story retelling ability.

     Maternal vaccination with tetanus, reduced-dose diphtheria, and acellular pertussis vaccine (Tdap) could be an effective way of mitigating the high residual burden of infant morbidity and mortality caused by Bordetella pertussis To better inform such interventions, we conducted a burden-of-disease study to determine the incidence of severe and nonsevere pertussis among a population of Zambian infants.  Mother-infant pairs were enrolled at 1 week of life, and then seen at 2- to 3-week intervals through 14 weeks of age. At each visit, nasopharyngeal (NP) swabs were obtained from both, and symptoms were catalogued. Using polymerase chain reaction (PCR) to identify cases, and a severity scoring system to triage these into severe/nonsevere, we calculated disease incidence using person-time at risk as the denominator.  From a population of 1981 infants, we identified 10 with clinical pertussis, for an overall incidence of 2.4 cases (95% confidence interval [CI], 1.2-4.2) per 1000 infant-months and a cumulative incidence of 5.2 cases (95% CI, 2.6-9.0) per 1000 infants. Nine of 10 cases occurred within a 3-month window (May-July 2015), with highest incidence between birth and 6 weeks of age (3.5 cases per 1000 infant-months), concentrated among infants prior to vaccination or among those who had only received 1 dose of Diphtheria Tetanus whole cell Pertussis (DTwP). Maternal human immunodeficiency virus (HIV) modestly increased the risk of infant pertussis (risk ratio, 1.8 [95% CI, .5-6.9]). Only 1 of 10 infant cases qualified as having severe pertussis. The rest presented with the mild and nonspecific symptoms of cough, coryza, and/or tachypnea. Notably, cough durations were long, exceeding 30 days in several cases, with PCRs repeatedly positive over time.  Pertussis is circulating freely among this population of Zambian infants but rarely presents with the classical symptoms of paroxysmal cough, whooping, apnea, and cyanosis. Maternal HIV appears to increase the

    Full Text Available Abstract Background The aim of this study, conducted in Europe, was to develop a validated risk factor based model to predict RSV-related hospitalisation in premature infants born 33–35 weeks' gestational age (GA. Methods The predictive model was developed using risk factors captured in the Spanish FLIP dataset, a case-control study of 183 premature infants born between 33–35 weeks' GA who were hospitalised with RSV, and 371 age-matched controls. The model was validated internally by 100-fold bootstrapping. Discriminant function analysis was used to analyse combinations of risk factors to predict RSV hospitalisation. Successive models were chosen that had the highest probability for discriminating between hospitalised and non-hospitalised infants. Receiver operating characteristic (ROC curves were plotted. Results An initial 15 variable model was produced with a discriminant function of 72% and an area under the ROC curve of 0.795. A step-wise reduction exercise, alongside recalculations of some variables, produced a final model consisting of 7 variables: birth ± 10 weeks of start of season, birth weight, breast feeding for ≤ 2 months, siblings ≥ 2 years, family members with atopy, family members with wheeze, and gender. The discrimination of this model was 71% and the area under the ROC curve was 0.791. At the 0.75 sensitivity intercept, the false positive fraction was 0.33. The 100-fold bootstrapping resulted in a mean discriminant function of 72% (standard deviation: 2.18 and a median area under the ROC curve of 0.785 (range: 0.768–0.790, indicating a good internal validation. The calculated NNT for intervention to treat all at risk patients with a 75% level of protection was 11.7 (95% confidence interval: 9.5–13.6. Conclusion A robust model based on seven risk factors was developed, which is able to predict which premature infants born between 33–35 weeks' GA are at highest risk of hospitalisation from RSV. The model could be

    Advances in perinatal care have resulted in increased survival rates for extremely low birth weight children, but it is fundamental to know if these improved survival rates have been accompanied by increased impairment rates. To compare, over two different time periods, the survival and disability rates at 2 years of corrected age, among newborns birth. Follow-up study that included 963 children born in the hospital between 1991 and 2004 who met the study criteria. Neonatal morbidity, mortality and disability to 2 years of corrected age in 2 time periods 1991-1998 (period I) and 1999-2004 (period II) have been evaluated and analysed by subgroups of weight (weight birth weight birth weight between 1000 and 1500 g ( 3,6% vs 9%). Analysing all children birth weight 1000-1500 g (67% vs 82%). In our study, globally analysing all children with birth weight birth weight 1000-1500 g subgroup.

    Physical and sedentary activity in children and adolescents has immediate health benefits and can also set a pattern that carries over into adulthood, resulting in long-term health benefits. Activity levels in a free-living biracial sample of children and adolescents, ages 9-15 yr (N = 995), were examined using a 24-h recall instrument, the Self-Administered Physical Activity Checklist. Selected sedentary activities (television watching and video-/computergame playing) were also assessed. Overall, boys were more physically active than girls and engaged in more heavy physical activity, while girls reported a larger percentage of time spent in light and moderate physical activities. Gender and, to a lesser extent, ethnic differences were seen in the types of activities reported. Although most physical activity occurred after school, children who reported no physical education class during school had less physical activity overall. There was a decrease in moderate physical activity with increasing grade levels in school and an increase in sedentary behavior. Black children reported more sedentary activity than white children, and girls reported more than boys. Although this 24-h recall method has limitations, it allows characterization of the activity of groups of children and provides useful data for policy recommendations.

    Background: Malnutrition in fetal life and during suckling have in some animal studies resulted in adaptive changes related to the fat and glucose metabolism, which in the long term might predispose the offspring for metabolic disorders such as obesity later in life. The objective was to study...... the effect of fetal life malnutrition in male mink on the gene expression of leptin and adiponectin in different adipose tissue sites. Results: Thirty-two male mink, strict carnivore species, exposed to low (FL) or adequate (FA) protein provision the last 16.3 ± 1.8 days of fetal life and randomly assigned.......5 weeks of age. Relative abundances of leptin and adiponectin mRNAs were different between adipose tissue sites and were significantly higher in subcutaneous than in perirenal and mesenteric tissues. Conclusion:Fetal life protein malnutrition in male mink, did not result in adaptive changes in the gene...

    This randomized, controlled, high-intensity strength and sprint training trial in middle-aged and older male sprint athletes showed significant improvements in mid-tibial structure and strength. The study reveals the adaptability of aging bone, suggesting that through a novel, intensive training stimulus it is possible to strengthen bones during aging. High-load, high-speed and impact-type exercise may be an efficient way of improving bone strength even in old age. We evaluated the effects of combined strength and sprint training on indices of bone health in competitive masters athletes, who serve as a group of older people who are likely to be able to participate in vigorous exercise of this kind. Seventy-two men (age 40-85) were randomized into an experimental (EX, n = 40) and a control (CTRL, n = 32) group. EX participated in a 20-week program combining heavy and explosive strength exercises with sprint training. CTRL maintained their usual, run-based sprint training schedules. Bone structural, strength and densitometric parameters were assessed by peripheral QCT at the distal tibia and tibial midshaft. The intervention had no effects on distal tibia bone traits. At the mid-tibia, the mean difference in the change in cortical thickness (Th CO ) in EX compared to CTRL was 2.0% (p = 0.007). The changes in structure and strength were more pronounced in the most compliant athletes (training adherence >75%). Compared to CTRL, total and cortical cross-sectional area, Th CO , and the area and density-weighted moments of inertia for the direction of the smallest flexural rigidity (I minA , I minD ) increased in EX by 1.6-3.2% (p = 0.023-0.006). Polar mass distribution analysis revealed increased BMC at the anteromedial site, whereas vBMD decreased (p = 0.035-0.043). Intensive strength and sprint training improves mid-tibia structure and strength in middle-aged and older male sprint athletes, suggesting that in the presence of high-intensity loading exercise

    The sequence of 436 nucleotides around the region coding for 5.8S RNA in the Sciara coprophila rDNA transcription unit (1) has been determined. Regions coding for 5.8S and 2S RNAs have been identified; they are 80 - 90% homologous to the corresponding Drosophila sequences and are separated by a 22 nucleotide long spacer. This sequence as well as the two before the 5.8 and after the 2S coding region are very different from the corresponding Drosophila sequences. The main features reported in the Drosophila study (2) are however also found, i.e. all three spacers are very rich in A-T; the sequence of the internal spacer allows base pairing; 5.8S and 2S RNAs can pair through their 3' and 5' terminal regions respectively. The features previously proposed as processing sites in the Drosophila case are thus all found in Sciara in spite of very different spacer sequences.

    Full Text Available We sought to determine the effects of L-leucine (LEU or different protein supplements standardized to LEU (~3.0 g/serving on changes in body composition, strength, and histological attributes in skeletal muscle and adipose tissue. Seventy-five untrained, college-aged males (mean ± standard error of the mean (SE; age = 21 ± 1 years, body mass = 79.2 ± 0.3 kg were randomly assigned to an isocaloric, lipid-, and organoleptically-matched maltodextrin placebo (PLA, n = 15, LEU (n = 14, whey protein concentrate (WPC, n = 17, whey protein hydrolysate (WPH, n = 14, or soy protein concentrate (SPC, n = 15 group. Participants performed whole-body resistance training three days per week for 12 weeks while consuming supplements twice daily. Skeletal muscle and subcutaneous (SQ fat biopsies were obtained at baseline (T1 and ~72 h following the last day of training (T39. Tissue samples were analyzed for changes in type I and II fiber cross sectional area (CSA, non-fiber specific satellite cell count, and SQ adipocyte CSA. On average, all supplement groups including PLA exhibited similar training volumes and experienced statistically similar increases in total body skeletal muscle mass determined by dual X-ray absorptiometry (+2.2 kg; time p = 0.024 and type I and II fiber CSA increases (+394 μm2 and +927 μm2; time p < 0.001 and 0.024, respectively. Notably, all groups reported increasing Calorie intakes ~600–800 kcal/day from T1 to T39 (time p < 0.001, and all groups consumed at least 1.1 g/kg/day of protein at T1 and 1.3 g/kg/day at T39. There was a training, but no supplementation, effect regarding the reduction in SQ adipocyte CSA (−210 μm2; time p = 0.001. Interestingly, satellite cell counts within the WPC (p < 0.05 and WPH (p < 0.05 groups were greater at T39 relative to T1. In summary, LEU or protein supplementation (standardized to LEU content does not provide added benefit in increasing whole-body skeletal muscle mass or strength above PLA

    There is a paucity of data on left ventricular (LV) rotational physiology, twist, and torsional mechanics in preterm infants. The principal aims of the present study were to assess the feasibility and reproducibility of measuring LV rotation, twist, and torsion in preterm infants (changes in those parameters over the first week after birth. This was a prospective observational study involving preterm infants time points. Intra- and interobserver reproducibility were assessed using Bland-Altman analysis and the intraclass correlation coefficient. Fifty-one infants with a mean ± SD gestational age of 26.8 ± 1.5 weeks and a mean birth weight of 945 ± 233 g were included. There was high intra- and interobserver reproducibility for basal and apical rotation, LV twist, and LV torsion, with intraclass correlation coefficients ranging from 0.78 to 0.96 (P fashion (11.8 ± 5.0° vs 12.1 ± 6.1° vs 11.7 ± 8.3°, P = .92). Basal rotation changed from counterclockwise on day 1 to clockwise on day 7 (median, 5.5° [interquartile range, -0.3° to 8.3°] vs 4.0 [interquartile range, -4.7° to 7.2°] vs -4.5° [interquartile range, -5.8° to -2.3°], P change in LVTR (P = .60), but LVUTR increased across the same time period (P = .01). Assessment of twist, LVTR, and LVUTR is feasible in preterm infants, with acceptable reproducibility. There are increases in LV twist and torsion in addition to LVUTR, suggesting changes in LV mechanics during the first week of age. Copyright © 2015 American Society of Echocardiography.

    1995-01-01

    Irradiated fuel from research and test reactors has been stored at various facilities for several decades. As these facilities age and approach or exceed their original design lifetimes, there is mounting concern about closure of the fuel cycle and about the integrity of ageing fuels from the materials point of view as well as some concern about the loss of self-protection of the fuels as their activity decays. It is clear that an international effort is necessary to give these problems sufficient exposure and to ensure that work begins on appropriate solutions. To obtain an overall picture of the size and extent of these problems, an Advisory Group Meeting on Storage Experience with Spent Fuel from Research Reactors was convened in Vienna 5-8 July 1993, and attended by twelve participants and three observers representing thirteen different countries. These proceedings contain the country reports presented at the meeting. Refs, figs and tabs

    The hypothesis that exposure to ionizing radiation accelerates the aging process has been actively investigated at ABCC-RERF since 1958, when longitudinal cohort studies of the Adult Health Study (AHS) and the Life Span Study (LSS) were initiated. In their 1975 overall review of aging studies related to the atomic bomb (A-bomb) survivors, Finch and Beebe concluded that while most studies had shown no correlation between aging and radiation exposure, they had not involved the large numbers of subjects required to provide strong evidence for or against the hypothesis. Extending LSS mortality data up to 1978 did not alter the earlier conclusion that any observed life-shortening was associated primarily with cancer induction rather than with any nonspecific cause. The results of aging studies conducted during the intervening 15 years using data from the same populations are reviewed in the present paper. Using clinical, epidemiological, and laboratory techniques, a broad spectrum of aging parameters have been studied, such as postmortem morphological changes, tests of functional capacity, physical tests and measurements, laboratory tests, tissue changes, and morbidity. With respect to the aging process, the overall results have not been consistent and are generally thought to show no relation to radiation exposure. Although some preliminary results suggest a possible radiation-induced increase in atherosclerotic diseases and acceleration of aging in the T-cell-related immune system, further study is necessary to confirm these findings. In the future, applying the latest gerontological study techniques to data collected from subjects exposed 45 years ago to A-bomb radiation at relatively young ages will present a new body of data relevant to the study of late radiation effects.

    The sequences of the ITS (internal transcribed spacer) and 5.8S rDNA of three cultivated strains of Porphyra haitanensis thalli (NB, PT and ST) were amplified, sequenced and analyzed. In addition, the phylogenic relationships of the sequences identified in this study with those of other Porphyra retrieved from GenBank were evaluated. The results are as follows: the sequences of the ITS and 5.8S rDNA were essentially identical among the three strains. The sequences of ITS1 were 331 bp to 334 bp, while those of the 5.8S rDNA were 158 bp and the sequences of ITS2 ranged from 673 bp to 681 bp. The sequences of the ITS had a high level of homology (up to 99.5%) with that of P. haitanensis (DQ662228) retrieved from GenBank, but were only approximately 50% homologous with those of other species of Porphyra. The results obtained when a phylogenetic tree was constructed coincided with the results of the homology analysis. These results suggest that the three cultivated strains of P. haitanensis evolved conservatively and that the ITS showed evolutionary consistency. However, the sequences of the ITS and 5.8S rDNA of different Porphyra species showed great variations. Therefore, the relationship of Porphyra interspecies phyletic evolution could be judged, which provides the proof for Porphyra identification study. However, proper classifications of the subspecies and the populations of Porphyra should be determined through the use of other molecular techniques to determine the genetic variability and rational phylogenetic relationships.

    Less-invasive treatment of caries has been needed in laser dentistry. Based on the absorption property of dentin substrates, 6 μm wavelength range shows specific absorptions and promising characteristics for the excavation. In our previous study, 5.8 μm wavelength range was found to be effective for selective excavation of carious dentin and restoration treatment using composite resin from the irradiation experiment with bovine sound and demineralized dentin. In this study, the availability of 5.8 μm wavelength range for selective excavation of human carious dentin was investigated for clinical application. A mid-infrared tunable nanosecond pulsed laser by difference-frequency generation was used for revealing the ablation property of human carious dentin. Irradiation experiments indicated that the wavelength of 5.85 μm and the average power density of 30 W/cm2 realized the selective excavation of human carious dentin, but ablation property was different with respect to each sample because of the different caries progression. In conclusion, 5.8 μm wavelength range was found to be effective for selective excavation of human carious dentin.

    The Pawnee M5.8 event is the largest earthquake in Oklahoma since instrumented history. How this earthquake affects known seismogenic areas in the state is a key issue for seismic hazard probability studies. In this study, we quantify stress loading and unloading on seismicity-delineated faults from the Oklahoma Geological Survey relocated-earthquake catalog. Our modeling indicates that areas in Noble, Pawnee, and Payne county are more prone to triggered seismicity, while areas in Alfalfa, Grant, Garfield, Logan, Major, Oklahoma, and Woods county are less prone to seismic triggering.

    Between 250,000 and 400,000 individuals in the United States are diagnosed with Down syndrome (DS). Nearly all adults with DS will develop Alzheimer's disease pathology starting in their thirties. Recent studies suggest that increased physical activity (PA) may be important for maintaining components of cognition, including memory. The purpose of this study was to evaluate changes in cognitive function after completion of a 12-week exercise intervention in adults with DS. Participants were randomized to attend 30-minute group exercise sessions 1 or 2 times a week for 12 weeks. The exercise sessions were delivered via video conferencing on a tablet computer to groups of 5-8 participants. Sessions consisted of aerobic based exercises such as walking and jogging to music, dancing, as well as strength based exercises such as vertical jumps, bicep curls, and squats. Cognitive function was measured at baseline and end of study using the Cantab Dementia Battery for iPads, which assessed the cognitive domains of memory, attention, and reaction time. Twenty-seven participants (27.9 ± 7.1 years of age, 40.7% female) enrolled and completed the 12-week intervention. Participants randomized to 1 session/week averaged 26.6 ± 3.0 min/week of PA from the group exercise session. Participants randomized to 2 sessions/week averaged 57.7 ± 15.3 min/week of PA from the group exercise sessions. Participants improved their performance on the two memory variables (p = 0.048 and p = 0.069). Increased exercise may have positive changes on memory and other cognitive functions.

    A warm and early October afternoon saw the beginning of the 2005 ATLAS overview week, which took place Rue de La Montagne Sainte-Geneviève in the heart of the Quartier Latin in Paris. All visitors had been warned many times by the ATLAS management and the organisers that the premises would be the subject of strict security clearance because of the "plan Vigipirate", which remains at some level of alert in all public buildings across France. The public building in question is now part of the Ministère de La Recherche, but used to host one of the so-called French "Grandes Ecoles", called l'Ecole Polytechnique (in France there is only one Ecole Polytechnique, whereas there are two in Switzerland) until the end of the seventies, a little while after it opened its doors also to women. In fact, the setting chosen for this ATLAS overview week by our hosts from LPNHE Paris has turned out to be ideal and the security was never an ordeal. For those seeing Paris for the first time, there we...

  3. Protective Effects of Quercetin and Quercetin-5',8-Disulfonate against Carbon Tetrachloride-Caused Oxidative Liver Injury in Mice

    Full Text Available Oxidative stress is one of the major factors in the pathogenesis of liver disease. Quercetin is a plant-based antioxidant traditionally used as a treatment for hepatic injury, but its poor solubility affects its bioavailability. We here report the regulative effects on hepatoprotection and absorption in mice of quercetin sulfation to form quercetin-5',8-disulfonate (QS, a novel synthetic compound. Oral administration of both QS and the parent quercetin at 100, 200 and 500 mg/kg·bw prior to acute CCl4 oxidative damage in mice, effectively attenuated serum alanine aminotransferase (ALT, aspartate aminotransferase (AST and lactate dehydrogenase (LDH activities and hepatic malondialdehyde (MDA levels (p < 0.05, and suppressed the CCl4-induced depletion of glutathione peroxidase (GSH-Px and total superoxide dismutase (T-SOD. Selective 5',8-sulfation of quercetin increased the hepatoprotective effect, and its relative absorption relative to quercetin (p < 0.05 as indicated by an improved 24-hour urinary excretion and a decreased fecal excretion determined by HPLC. These results and histopathological observations collectively demonstrate that quercetin sulfation increases its hepatoprotective effects and absorption in mice, and QS has potential as a chemopreventive and chemotherapeutic agent for liver diseases.

  4. Sequence Variation in the Ribosomal Internal Transcribed Spacers, Including the 5.8S rDNA, of Naegleria spp.

    The ribosomal internal transcribed spacer (ITS), including the 5.8S rDNA, from the majority of the 11 described species of the amoeboflagellate Naegleria and from Willaertia magna have a size between 300 and 450 bp. In N. jadini and N. minor these products are approximately 750 bp long. The products from strains of the pathogenic N. fowleri vary between 323 and 423 bp. These length variations in N. fowleri are due to insertions of short repeats in the ITS1, causing the elongation of one stem-loop in the putative secondary structure. In all other species the sizes were identical from strains of the same species. In N. jadini and N. minor there are long inserts in the ITS2. Naegleria italica, N. clarki and N. galeacystis have shorter inserts in the ITS2. These inserts cause the elongation of one stem-loop in the putative secondary structure proposed for the ITS2. Because of the small differences in sequence between N. fowleri and N. lovaniensis the ITS does not provide target sequences for specifically identifying the pathogenic N. fowleri. However, differences in ITS1 do allow to distinguish different N. fowleri isolates. The ITS and 5.8S rDNA sequences will be of additional help in describing new Naegleria spp., which becomes more based on molecular data because morphological differences are scarce in these organisms.

    The prevalence of Candida in bloodstream infections (BSIs) has increased. To date, the identification of Candida in BSIs still mainly relies on blood culture and serological tests, but they have various limitations. Therefore, a real-time PCR assay for the detection of Candida from whole blood is presented. The unique primers/probe system was designed on 5.8S rRNA gene (5.8S rDNA) of Candida genus. The analytical sensitivity was determined by numbers of positive PCRs in 12 repetitions. At the concentration of 10(1) CFU/ml blood, positive PCR rates of 100 % were obtained for C. albicans, C. parapsilosis, C. tropicalis, and C. krusei. The detection rate for C. glabrata was 75 % at 10(1) CFU/ml blood. The reaction specificity was 100 % when evaluating the assay using DNA samples from clinical isolates and human blood. The maximum CVs of intra-assay and inter-assay for the detection limit were 1.22 and 2.22 %, respectively. To assess the clinical applicability, 328 blood samples from 82 patients were prospectively tested and real-time PCR results were compared with results from blood culture. Diagnostic sensitivity of the PCR was 100 % using as gold standard blood culture, and specificity was 98.4 %. Our data suggest that the developed assay can be used in clinical laboratories as an accurate and rapid screening test for the Candida from whole blood. Although further evaluation is warranted, our assay holds promise for earlier diagnosis of candidemia.

    The isolation and structural characterization are described of the major monoaddition products formed in the photoreaction of two naturally occurring psoralens, 8-methoxypsoralen and 4,5',8-trimethylpsoralen, with high molecular weight, double-stranded DNA. Hydrolysis of the psoralen-modified DNA and subsequent chromatography resulted in the isolation of four modified nucleosides from each psoralen. Structural characterization was accomplished by mass spectrometry and 1 H NMR analysis. The major products, accounting for 44 to 52% of the covalently bound psoralen, are two diastereomeric thymidine adducts formed by cycloaddition between the 5,6 double bond of the pyrimidine and the 4',5' (furan) double bond of the psoralen. All of the isolated adducts have cis-syn stereochemistry. The stereochemistry and product distribution of the adducts are determined in part by the constraints imposed by the DNA helix on the geometry of the noncovalent intercalation complex formed by psoralen and DNA prior to irradiation

    Extraction of uranium(VI) by a liquid surfactant membrane has been studied. The stability of water-in-oil (w/o) emulsion dispersed in the continuous aqueous phase increased with an increase in surfactant concentrations and in the fraction of the organic phase in emulsion globules. Uranium(VI) in dilute acid solutions was extracted into (w/o) emulsions containing 5,8-diethyl-7-hydroxy-6-dodecanone oxime (LIX 63) as a mobile carrier and its concentration decreased according to [U]sub(t)=[U]sub(o)exp(-ksub(obsd)t). The apparent rate constants (ksub(obsd)) increased with an increase in carrier concentrations and in external pH values, while they were slightly dependent on the stripping acid concentrations. Uranium was transported and concentrated into the internal aqueous droplets. The final concentration of uranium in the external aqueous phase dropped to about 10 -3 of its initial value. (author)

    Myc-interacting zinc finger protein-1 (Miz-1) is a BTB/POZ transcription factor that activates the transcription of cytostatic genes, such as p15{sup INK4B} or p21{sup CIP1}. The C-terminus of Miz-1 contains 13 consensus C{sub 2}H{sub 2} zinc finger domains (ZF). ZFs 1-4 have been shown to interact with SMAD3/4, while the remaining ZFs are expected to bind the promoters of target genes. We have noted unusual features in ZF 5 and the linker between ZFs 5 and 6. Indeed, a glutamate is found instead of the conserved basic residue two positions before the second zinc-coordinating histidine on the ZF 5 helix, and the linker sequence is DTDKE in place of the classical TGEKP sequence. In a canonical {beta}{beta}{alpha} fold, such unusual primary structure elements should cause severe electrostatic repulsions. In this context, we have characterized the structure and the dynamics of a Miz-1 construct comprising ZFs 5-8 (Miz 5-8) by solution-state NMR. Whilst ZFs 5, 7 and 8 were shown to adopt the classical {beta}{beta}{alpha} fold for C{sub 2}H{sub 2} ZFs, the number of long-range NOEs was insufficient to define a classical fold for ZF 6. We show by using {sup 15}N-relaxation dispersion experiments that this lack of NOEs is due to the presence of extensive motions on the {mu}s-ms timescale. Since this negatively charged region would have to be located near the phosphodiester backbone in a DNA complex, we propose that in addition to promoting conformational searches, it could serve as a hinge region to keep ZFs 1-4 away from DNA.

    Boundary layer transition on high-speed vehicles is expected to be affected by unsteady surface compliance. The stability properties of a Mach 5.8 zero-pressure-gradient laminar boundary layer grazing a nominally-flat thermo-mechanically compliant panel is considered. The linearized compressible Navier-Stokes equations describe small amplitude disturbances in the fluid while the panel deformations are described by the Kirchhoff-Love plate equation and its thermal state by the transient heat equation. Compatibility conditions that couple disturbances in the fluid to those in the solid yield simple algebraic and robin boundary conditions for the velocity and thermal states, respectively. A local convective stability analysis shows that the panel can modify both the first and second Mack modes when, for metallic-like panels, the panel thickness exceeds the lengthscale δ99 Rex- 0 . 5 . A global stability analysis, which permits finite panel lengths with clamped-clamped boundary conditions, shows a rich eigenvalue spectrum with several branches. Unstable modes are found with streamwise-growing panel deformations leading to Mach wave-type radiation. Stable global modes are also found and have distinctly different panel modes but similar radiation patterns. Air Force Office of Scientific Research.

    The 2016 Mw 5.8 Pawnee earthquake occurred in a region with active wastewater injection into a basal formation group. Prior to the earthquake, fluid injection rates at most wells were relatively steady, but newly collected data show significant increases in injection rate in the years leading up to earthquake. For the same time period, the total volumes of injected wastewater were roughly equivalent between variable‐rate and constant‐rate wells. To understand the possible influence of these changes in injection, we simulate the variable‐rate injection history and its constant‐rate equivalent in a layered poroelastic half‐space to explore the interplay between pore‐pressure effects and poroelastic effects on the fault leading up to the mainshock. In both cases, poroelastic stresses contribute a significant proportion of Coulomb failure stresses on the fault compared to pore‐pressure increases alone, but the resulting changes in seismicity rate, calculated using a rate‐and‐state frictional model, are many times larger when poroelastic effects are included, owing to enhanced stressing rates. In particular, the variable‐rate simulation predicts more than an order of magnitude increase in seismicity rate above background rates compared to the constant‐rate simulation with equivalent volume. The observed cumulative density of earthquakes prior to the mainshock within 10 km of the injection source exhibits remarkable agreement with seismicity predicted by the variable‐rate injection case.

    Skeletal patterning in the sea urchin embryo requires coordinated signaling between the pattern-dictating ectoderm and the skeletogenic primary mesenchyme cells (PMCs); recent studies have begun to uncover the molecular basis for this process. Using an unbiased RNA-Seq-based screen, we have previously identified the TGF-ß superfamily ligand, LvBMP5-8, as a skeletal patterning gene in Lytechinus variegatus embryos. This result is surprising, since both BMP5-8 and BMP2/4 ligands have been implicated in sea urchin dorsal-ventral (DV) and left-right (LR) axis specification. Here, we demonstrate that zygotic LvBMP5-8 is required for normal skeletal patterning on the left side, as well as for normal PMC positioning during gastrulation. Zygotic LvBMP5-8 is required for expression of the left-side marker soxE, suggesting that LvBMP5-8 is required for left-side specification. Interestingly, we also find that LvBMP5-8 knockdown suppresses serotonergic neurogenesis on the left side. While LvBMP5-8 overexpression is sufficient to dorsalize embryos, we find that zygotic LvBMP5-8 is not required for normal DV specification or development. In addition, ectopic LvBMP5-8 does not dorsalize LvBMP2/4 morphant embryos, indicating that, in the absence of BMP2/4, BMP5-8 is insufficient to specify dorsal. Taken together, our data demonstrate that zygotic LvBMP5-8 signaling is essential for left-side specification, and for normal left-side skeletal and neural patterning, but not for DV specification. Thus, while both BMP2/4 and BMP5-8 regulate LR axis specification, BMP2/4 but not zygotic BMP5-8 regulates DV axis specification in sea urchin embryos. Copyright © 2016 Elsevier Inc.

    The purpose of our study was to evaluate the effects of six weeks of Pilates regarding functional balance, fear of falling and pain in community living women older than 65 years old with chronic low-back pain. A single blind controlled randomized trial of six weeks of Pilates in addition to physiotherapy treatment (n=50) vs. physiotherapy treatment alone (n=47) was conducted on 97 community living women (71.14 ± 3.30 years) with chronic low-back pain (CLBP). Main outcome measures were fear of falling (FoF), assessed by the Falls Efficacy Scale-international; functional mobility and balance, measured with the Timed up and Go Test; and pain, evaluated using the numeric rating scale. Only the Pilates group showed improvement in FoF (ES; d=.68) and functional mobility and balance (ES; d=1.12) after treatment, and also had better results in pain (ES; d=1.46) than the physiotherapy-only group. Six weeks of Pilates exercises may be effective in fall prevention through the improvement of FoF, functional balance, and pain in Spanish women over 65 years old with CLBP.

    The M5.8 23 August 2011 Mineral, Virginia, earthquake was felt over nearly the entire eastern United States and was recorded by a wide array of seismic broadband instruments. The earthquake occurred ~200 km southeast of the boundary between two distinct geologic belts, the Piedmont and Blue Ridge terranes to the southeast and the Valley and Ridge Province to the northwest. At a dominant period of 3 s, coherent postcritical P-wave (i.e., direct longitudinal waves trapped in the crustal waveguide) arrivals persist to a much greater distance for propagation paths toward the northwest quadrant than toward other directions; this is probably related to the relatively high crustal thickness beneath and west of the Appalachian Mountains. The seismic surface-wave arrivals comprise two distinct classes: those with weakly dispersed Rayleigh waves and those with strongly dispersed Rayleigh waves. We attribute the character of Rayleigh wave arrivals in the first class to wave propagation through a predominantly crystalline crust (Blue Ridge Mountains and Piedmont terranes) with a relatively thin veneer of sedimentary rock, whereas the temporal extent of the Rayleigh wave arrivals in the second class are well explained as the effect of the thick sedimentary cover of the Valley and Ridge Province and adjacent Appalachian Plateau province to its northwest. Broadband surface-wave ground velocity is amplified along both north-northwest and northeast azimuths from the Mineral, Virginia, source. The former may arise from lateral focusing effects arising from locally thick sedimentary cover in the Appalachian Basin, and the latter may result from directivity effects due to a northeast rupture propagation along the finite fault plane.

    The 2016 M5.8 Gyeongju earthquake, the largest event in Korea since 1978, occurred at 05:38:47 UTC on 12 September, the south-eastern province of the Korean peninsula (35.77°N, 129.18°E). It provided an opportunity to examine the changes in groundwater responding to the local moderated-scale earthquake. We obtained the long-term monitoring data which were recorded in every hour from the National Groundwater Monitoring Network (NGMN). The depths of monitoring wells range from 70 to 200m, and have three screening sections. From the daily data, 46 out of 440 wells in the country-wide were qualitatively identified as influenced. However, the data interval of 1-day is too large to detect the short-term responses, and there was uncertainty issue remained due to interferences by heavy rainfall on 12 and 13 September. Therefore, we identified the abrupt changes (outliers) in long-term data of water level, temperature, and electric conductivity. The time span of data was set as from February 2015 to January 2017 to identify the possible precursory movement. For the water-level data, the effects of rainfall and earth tides were statistically removed prior to identification abrupt changes. By the primary test of this study, 43 and nine wells were identified as influenced by the earthquake in water level and temperature, respectively. The further analysis including the identification of precursory changes and comparison with the results from previous researches on the impacts of near and distant earthquakes is under progression.

    Full Text Available Objective: The goal of this research is to attest Covert Repair Hypothesis (CRH i.e, discovering the phonological loop of the word production process in stuttering children. Materials & Methods: In this analytical (Case – Control research, forty bisyllabic and trisyllabic nonwords were designed. After the pilot study, these nonwords were presented to twelve stuttering children with the ages 5-8 and twelve nonstuttering children by the use of DMDX software. Children were asked to repeat the nonwords immediately after hearing them, the reaction time were recorded by the DMDX. The number of phonological errors and correct responses were determined. Results: Findings proved that stuttering children in all its forms except of reaction time of trisyllabic nonwords had a weak performance. However, the research results were not statistically significant. Conclusion: The study evidences show differences between stuttering and nonstuttering children performances. This may outline the possible of defect in language processes of stuttering children, especially in phonological encoding of word production mechanism. Also, the difference pattern between groups had coordination with CRH assumptions.

    To compare the effects of two energy-restricted healthy diets, one with a low GI and one with a high GI, on heart disease risk factors and weight loss in subjects at risk of heart disease. A 12-week randomized parallel study of low and high GI, healthy eating diets was carried out. The study was carried out at the Hammersmith Hospital. Eighteen subjects were recruited by advertisement and randomized to one of the two diets. Fourteen completed the study but one was excluded from the final analysis. At randomization, subjects were advised to follow the intervention diet for 12 weeks. Before randomization and on completion of the study, anthropometrics, fasting cholesterol and glucose blood tests and 24-h glucose measurements were taken using a continuous glucose monitoring system (CGMS). Statistical analysis was carried out using non-parametric tests. Median (IQR) are presented. A significantly different dietary GI was achieved in the low GI (median: 51.3 (IQR: 51.0-52.0) compared to the high GI (59.3 (59.2-64.0) (P=0.032) group. By week 12, both groups reduced their energy intake by: low GI group: (-)167 ((-)312-(-)123) kcal/day (P=0018) vs high GI group: (-)596 ((-)625-(-)516) (P=0.018) kcal/day, the difference between the groups being significant (P=0.010). However, only the low GI group lost weight ((-)4.0 ((-)4.4-(-)2.4) kg (P=0.018) whereas the high GI group did not significantly change in weight ((-)1.5 ((-)3.6-0.8) kg (P=0.463). By week 12, the low GI group also had a significantly lower 24-h area under the curve (AUC) (7556 (7315-8434) vs 8841 (8424-8846) mmol-h/l (P=0.045) and overnight AUC (2429 (2423-2714) vs 3000 (2805-3072) mmol-h/l (P=0.006) glucose as measured by CGMS. There were no differences in the other heart disease risk factors assessed. This pilot study provides some evidence that consuming a low GI diet in addition to weight loss and healthy eating may reduce cardiovascular risk. Other potential benefits of GI might have been masked by weight

    Solar Week is a week-long set of games and activities allowing students to interact directly with solar science and solar scientists. Solar Week was developed as a spin-off of the highly successful Yohkoh Public Outreach Project (YPOP). While YPOP provided access to solar images, movies and activities, the main goal of Solar Week was to enhance the participation of women, who are under-represented in the physical sciences. Solar Week achieves this by providing young women, primarily in grades 6-8, with access to role models in the sciences. The scientists participating in Solar Week are women from a variety of backgrounds and with a variety of scientific expertise. In this paper, our aim is to provide some insight into developing activity-based space science for the web and to discuss the lessons-learned from tailoring to a specific group of participants.

    Space-time fluctuations of Earth's emitted Thermal Infrared (TIR) radiation have been observed from satellite months to weeks before earthquakes occurrence. Different authors, in order to explain the appearance of anomalously high TIR records near the place and the time of earthquake occurrence, attributed their appearance to the increase of green-house gas (such as CO2, CH4, etc.) emission rates, to the modification of ground water regime and/or to the increase of convective heat flux. In this contest, an approach called Robust Satellite Techniques (RST) has been proposed in order to discriminate normal (i.e. related to the change of natural factor and/or observation conditions) TIR signal fluctuations from anomalous signal transient possibly associated to earthquake occurrence. In the past RST was already tested in the case of tens of earthquakes with a wide range of magnitudes (from 4.0 to 7.9) occurred in different continents and in various geo-tectonic setting (e.g. 1980 Irpinia-Basilicata earthquake; Izmit earthquake, 17 August 1999; Hector Mine earthquake, 16 October 1999, etc.). The RST analysis is based on a statistically definition of "TIR anomalies" and a suitable method for their identification even in very different local (e.g. related to atmosphere and/or surface) and observational (e.g. related to time/season, but also to solar and satellite zenithal angles) conditions, and has been always carried out by using a validation/confutation approach, to verify the presence/absence of anomalous space-time TIR transients in the presence/absence of seismic activity. In this work the same approach is applied to the case of Abruzzo 6 April 2009 event (ML=5.8) and compared with an identical analysis (confutation) performed in seismically unperturbed years. RST analysis was performed on a historical data set made of 30 years of contemporary observations done by 3 independent satellite systems (5 years of MSG/SEVIRI, 15 years of NOAA/AVHRR and 10 years of EOS

    Studies assessing the effects of protein supplementation on changes in body composition (BC) and health rarely consider the impact of total protein intake (TPro) or the change in TPro (CTPro) from participants' usual diets. This secondary data analysis assessed the impact of TPro and CTPro on changes in BC and metabolic syndrome (MetS) indexes in overweight and obese middle-aged adults who participated in an exercise training program. Men and women [n = 117; age: 50 ± 0.7 y, body mass index (BMI; in kg/m(2)): 30.1 ± 0.3; means ± SEs] performed resistance exercise 2 d/wk and aerobic exercise 1 d/wk and consumed an unrestricted diet along with 200-kcal supplements (0, 10, 20, or 30 g whey protein) twice daily for 36 wk. Protein intake was assessed via 4-d food records. Multiple linear regression model and stratified analysis were applied for data analyses. Among all subjects, TPro and CTPro were inversely associated (P changes in body mass, fat mass (FM), and BMI. Changes in BC were different (P changes in FM, %FM, and %LM. The gain in LM was not different among groups. In addition, MetS indexes were not influenced by TPro and CTPro. In conjunction with exercise training, higher TPro promoted positive changes in BC but not in MetS indexes in overweight and obese middle-aged adults. Changes in TPro from before to during the intervention also influenced BC responses and should be considered in future research when different TPro is achieved via diet or supplements.

    Small RNAs derived from ribosomal RNAs (srRNAs) are rarely explored in the high-throughput data of plant systems. Here, we analyzed srRNAs from the deep-sequenced small RNA libraries of Piper nigrum, a unique magnoliid plant. The 5' end of the putative long form of 5.8S rRNA (5.8S L rRNA) was identified as the site for biogenesis of highly abundant srRNAs that are unique among the Piperaceae family of plants. A subsequent comparative analysis of the ninety-seven sRNAomes of diverse plants successfully uncovered the abundant existence and precise cleavage of unique rRF signature small RNAs upstream of a novel 5' consensus sequence of the 5.8S rRNA. The major cleavage process mapped identically among the different tissues of the same plant. The differential expression and cleavage of 5'5.8S srRNAs in Phytophthora capsici infected P. nigrum tissues indicated the critical biological functions of these srRNAs during stress response. The non-canonical short hairpin precursor structure, the association with Argonaute proteins, and the potential targets of 5'5.8S srRNAs reinforced their regulatory role in the RNAi pathway in plants. In addition, this novel lineage specific small RNAs may have tremendous biological potential in the taxonomic profiling of plants.

    Full Text Available Lack of bone formation-related health problems are a major problem for the aging population in the modern world. As a part of the ongoing trend of developing natural substances that attenuate osteoporotic bone loss conditions, dioxinodehydroeckol (DHE from edible brown alga Ecklonia cava was tested for its effects on osteoblastogenic differentiation in MC3T3-E1 pre-osteoblasts. DHE was observed to successfully enhance osteoblast differentiation, as indicated by elevated cell proliferation, alkaline phosphatase activity, intracellular cell mineralization, along with raised levels of osteoblastogenesis indicators at the concentration of 20 μM. Results suggested a possible intervening of DHE on the bone morphogenetic protein (BMP signaling pathway, according to elevated protein levels of BMP-2, collagen-I, and Smads. In addition, the presence of DHE was also able to raise the phosphorylated extracellular signal–regulated kinase (ERK and c-Jun N-terminal kinase (JNK levels which are also activated by the BMP signaling pathway. In conclusion, DHE is suggested to be a potential bioactive compound against bone loss that could enhance osteoblastogenesis with a suggested BMP pathway interaction.

    Multiple lines of evidence have indicated that the dose of hemodialysis (HD) affects patient outcome. According to K-DOQI, daily spKt/V > 1.2 predicts the morbidity and mortality among thrice-weekly HD. However in developing countries, about three-fourths of end stage renal disease patients undergo twice-weekly HD. No data studied the outcome and nutritional status between twice- and thrice-weekly HD patients. To compare the nutritional parameters in twice- and thrice-weekly HD patients who had weekly Kt/V > 3.6. The cross-sectional study was performed in the HD unit of the National Kidney Foundation of Thailand. One hundred and forty two informed consent HD patients were enrolled in the present study. Nutritional status was evaluated following a HD treatment by bioelectrical impedance analysis. All patients were interviewed for three-day food record and data were analyzed by Inmucal software program. Sixty patients had thrice-weekly HD and 82 patients were on twice-weekly HD. The characteristics and duration of dialysis of both groups were similar except age. Duration of dialysis in thrice-weekly HD group was 82.64 +/- 50 82 and twice-weekly HD group was 68.92 +/- 31.49 months. The mean age of the thrice-weekly HD group and twice-weekly HD group patients were 47.78 +/- 9.89 and 41.63 +/- 10.47 years, respectively (p nutrition parameters except daily energy intake which was lower in the thrice-weekly HD group than twice-weekly HD group (19.21 +/- 6.42 vs. 25.02 +/- 7.70 kcal/kg/day, p patients with delivered weekly Kt/V > 3.6, nutritional status of patients undergoing twice-weekly HD are not different from that of thrice-weekly HD patients. Higher energy intake in twice-weekly HD patients might be the explanation.

    The influence of grinding size of the main cereal of the diet on production and egg quality traits was studied in brown hens from 33 to 65 wk of age. The experiment was completely randomized with 6 treatments arranged as a 3 × 2 factorial with 3 main cereals (barley, corn, and wheat) and 2 grinding size of the cereal (6 and 10 mm screen). Each treatment was replicated 11 times (10 hens/replicate). Diets were isonutritive and contained 2,740 kcal/kg AMEn and 16.8% CP. Egg production, ADFI, egg weight, and feed conversion ratio (FCR) were determined by period (4 wk) and for the entire experiment. Egg quality traits (percentage of undergrades, Haugh units, thickness, strength, color of the shell, and proportion of albumen, yolk, and shell) were measured also by period. No interactions between main cereal and grinding size of the main cereal of the diet were observed for any of the traits studied. Feed intake, egg production, and BW gain were not affected by diet or grinding size. Eggs were heavier (P hens fed barley than in hens fed corn or wheat, probably because of the higher fat content of the barley diets. Also, FCR tended to improve in hens fed barley compared with hens fed corn or wheat (P = 0.07). Diet did not affect any of the egg quality traits studied. In summary, barley and wheat conveniently supplemented with enzymes, can be used in substitution of corn at levels of up to 55% in diets for laying hens, without any adverse effect on egg production or egg quality traits. Moreover, the substitution of corn by a combination of barley and supplemental fat increased egg size. Consequently, the inclusion of one or other cereal in the diet will depend primarily on their relative cost. Within the range studied, screen size (6 vs. 10 mm) of the cereal had limited effects on hen production.

    The ATLAS Overview Weeks always provide a good opportunity to see the status and progress throughout the experiment, and the July week at Glasgow University was no exception. The setting, amidst the traditional buildings of one of the UK's oldest universities, provided a nice counterpoint to all the cutting-edge research and technology being discussed. And despite predictions to the contrary, the weather at these northern latitudes was actually a great improvement on the previous few weeks in Geneva. The meeting sessions comprehensively covered the whole ATLAS project, from the subdetector and TDAQ systems and their commissioning, through to offline computing, analysis and physics. As a long-time ATLAS member who remembers plenary meetings in 1991 with 30 people drawing detector layouts on a whiteboard, the hardware and installation sessions were particularly impressive - to see how these dreams have been translated into 7000 tons of reality (and with attendant cabling, supports and services, which certainly...

    Internal transcribed spacers (ITS) and the 5.8S ribosomal gene of 21 Naegleria fowleri strains and eight other species including Naegleria gruberi were sequenced. The results showed that this region can help differentiate between and within species. The phylogeny of Naegleria spp. deduced from the ITS and the 5.8S gene produced four major lineages, fowleri-lovaniensis, galeacystis-italica-clarki-gruberi-australiensis, andersoni-jamiesoni, and pussardi, that fit perfectly with those inferred from the 18S rRNA gene analysis. The N. gruberi isolate, NG260, was closely related to Naegleria pussardi. The other N. gruberi isolates branched together with Naegleria australiensis in another lineage. The ITS and 5.8S results for N. fowleri were congruent with those previously deduced by RAPD analysis. The phylogenetic analysis inferred from ITS and RAPD data revealed two major groups. The French Cattenom and Chooz and South Pacific strains constituted the first group. The second group encompassed the strains corresponding to the Euro-American and Widespread RAPD variants and shared the same substitution in the 5.8S gene. In addition, it was possible to define species specific primers in ITS regions to rapidly identify N. fowleri.

    Green algae, Chlorella ellipsoidea , Haematococcus pluvialis and Aegagropila linnaei (Phylum Chlorophyta) were simultaneously decoded by a genomic skimming approach within 18-5.8-28S rRNA region. Whole genomic DNAs were isolated from green algae and directly subjected to low coverage genome skimming sequencing. After de novo assembly and mapping, the size of complete 18-5.8-28S rRNA repeated units for three green algae were ranged from 5785 to 6028 bp, which showed high nucleotide diversity (π is around 0.5-0.6) within ITS1 and ITS2 (Internal Transcribed Spacer) regions. Previously, the evolutional diversity of algae has been difficult to decode due to the inability design universal primers that amplify specific marker genes across diverse algal species. In this study, our method provided a rapid and universal approach to decode the 18-5.8-28S rRNA repeat unit in three green algal species. In addition, the completely sequenced 18-5.8-28S rRNA repeated units provided a solid nuclear marker for phylogenetic and evolutionary analysis for green algae for the first time.

    The outreach programme Semanas da Astronomia (Astronomy Weeks) is held in late spring or summer on the island of Madeira, Portugal. This programme has been attracting enough interest to be mentioned in the regional press/TV/radio every year and is now, without doubt, the astronomical highlight of the year on Madeira. We believe that this programme is a good case study for showing how to attract the general public to astronomy in a small (population 250 000, area 900 km2) and fairly isolated place such as Madeira. Our Astronomy Weeks have been different each year and have so far included exhibitions, courses, talks, a forum, documentaries, observing sessions (some with blackouts), music and an astro party. These efforts may contribute towards putting Madeira on the map with respect to observational astronomy, and have also contributed to the planned installation of two observatories in the island.

    Pilcher, J

    Over 200 ATLAS participants gathered at Brookhaven National Laboratory during the first week of June for our annual overview week. Some system communities arrived early and held meetings on Saturday and Sunday, and the detector interface group (DIG) and Technical Coordination also took advantage of the time to discuss issues of interest for all detector systems. Sunday was also marked by a workshop on the possibilities for heavy ion physics with ATLAS. Beginning on Monday, and for the rest of the week, sessions were held in common in the well equipped Berkner Hall auditorium complex. Laptop computers became the norm for presentations and a wireless network kept laptop owners well connected. Most lunches and dinners were held on the lawn outside Berkner Hall. The weather was very cooperative and it was an extremely pleasant setting. This picture shows most of the participants from a view on the roof of Berkner Hall. Technical Coordination and Integration issues started the reports on Monday and became a...

    Phthalate diesters are commonly used and have been well established as environmental endocrine disruptors. However, few studies have examined their effects on sex steroid hormones in children. We followed children over time to examine the association between pre- and post-natal phthalate exposure and sex steroid hormone levels at 2, 5, 8, and 11 years of age. We recruited 430 pregnant women from central Taiwan from 2000 to 2001 and assessed their children at birth, 2, 5, 8, and 11 years of age. We studies children with at least one measurement for both phthalate and hormone levels during each any of the follow-up time point (n = 193). Estradiol, free testosterone, testosterone, and progesterone were measured from venous blood. Three monoesters of di-2-ethylhexyl phthalate (DEHP), mono-benzyl phthalate, mono-n-butyl phthalate, mono-ethyl phthalate, and mono-methyl phthalate were measured in maternal urine collected during the 3rd trimester and child urine collected at each follow-up point. The sum of mono-2-ethylhexyl phthalate (∑MEHP) was calculated by summing the concentrations of the three DEHP monoesters. Generalized estimating equation regression analysis with repeated measures was used to estimate associations between phthalate metabolites and hormone levels. After adjustment for potential confounders, maternal ∑MEHP level was associated with decreased levels of progesterone in girls (β = -0.309 p = 0.001). The child ∑MEHP concentration was associated with decreased levels of progesterone for girls (β = -0.194, p = 0.003) and with decreased levels of free testosterone for boys (β = -0.124, p = 0.004). Early-life DEHP exposure may alter sex steroid hormones of children over time, which may pose potential reproductive health risks. Copyright © 2017 The Authors.

    The secondary structure of mouse Ehrlich ascites 18S, 5.8S and 28S ribosomal RNA in situ was investigated by chemical modification using dimethyl sulphate and 1-cyclohexyl-3-(morpholinoethyl) carbodiimide metho-p-toluene sulphonate. These reagents specifically modify unpaired bases in the RNA. The reactive bases were localized by primer extension followed by gel electrophoresis. The three rRNA species were equally accessible for modification i.e. approximately 10% of the nucleotides were reactive. The experimental data support the theoretical secondary structure models proposed for 18S and 5.8/28S rRNA as almost all modified bases were located in putative single-strand regions of the rRNAs or in helical regions that could be expected to undergo dynamic breathing. However, deviations from the suggested models were found in both 18S and 28S rRNA. In 18S rRNA some putative helices in the 5'-domain were extensively modified by the single-strand specific reagents as was one of the suggested helices in domain III of 28S rRNA. Of the four eukaryote specific expansion segments present in mouse Ehrlich ascites cell 28S rRNA, segments I and III were only partly available for modification while segments II and IV showed average to high modification.

    EEW(Earthquake Early Warning) service to the public has been officially operated by KMA (Korea Meteorological Administration) from 2015 in Korea. For the KMA's official EEW service, KIGAM has adopted ElarmS from UC Berkeley BSL and modified local magnitude relation, 1-D travel time curves and association procedures with real time waveform from about 201 seismic stations of KMA, KIGAM, KINS and KEPRI. There were two moderate size earthquakes with magnitude Ml 5.1 and Ml 5.8 close to Gyeongju city located at the southeastern part of Korea on Sep. 12. 2016. We have checked the performance of EEWS(Earthquake Early Warning System) named as TrigDB by KIGAM reviewing of these two Gyeongju earthquakes. The nearest station to epicenters of two earthquakes Ml 5.1(35.7697 N, 129.1904 E) and Ml 5.8(35.7632 N, 129.1898 E) was MKL which detected P phases in about 2.1 and 3.6 seconds after the origin times respectively. The first events were issued in 6.3 and 7.0 seconds from each origin time. Because of the unstable results on the early steps due to very few stations and unexpected automated analysis, KMA has the policy to wait for more 20 seconds for confirming the reliability. For these events KMA published EEW alarms in about 26 seconds after origin times with M 5.3 and M 5.9 respectively.

    2009-01-01

    This has been a busy week for the CERN Council, and there is much to report. Firstly, I’m pleased to say that Council approved the Organization’s Medium Term Plan, and with it the budget for financial year 2010. In a time of global recession, this is a strong vote of confidence from the Member States. This meeting of Council provided an opportunity for the working group on the scientific and geographical enlargement of CERN to set out a roadmap towards its final report, which is to be made at Council’s December session this year. One part of the process over the coming months is to bring the major players in particle physics from beyond the European region into the discussion, ensuring that the working group’s recommendations lead to an optimum position for CERN and European particle physics in the global context. An indicator of the continuing attractiveness of CERN is the fact that Council has received four new applications...

Se midieron las ganancias de peso vivo y el rendimiento y la calidad del pastizal y de las arbóreas. El pastoreo se realizó con 36 animales, en un área de la vaquería de la EEPF ¨Indio Hatuey¨(12 ha. La leucaena y los pastos se establecieron en años anteriores. La densidad de la arbórea fue de 555 árboles/ha y la poda en el período seco se efectuó a una altura de 150 cm. Se empleó una carga global de 3 animales/ha; la rotación fue de 50 días en la época poco lluviosa y de 40 días en la lluviosa. Los animales dispusieron de agua y sales minerales durante las 24 horas del día. No se ofreció suplementación energética ni proteica. La oferta diaria de pastos en el período seco estuvo alrededor de los 11 kg de MS/100 kg de PV/día al inicio y fue superior a los 7 kg al final; por concepto de poda y ramoneo de arbóreas los valores oscilaron entre los 0,295 y 0,133 kg de MS/100 kg de PV/día. En el período lluvioso la oferta de pastos fue de 16,85 kg de MS/100 kg de PV/día; mientras que la disponibilidad de leucaena en ramoneo superó los 0,285 kg de MS/100 kg de PV/día. La ganancia diaria de peso vivo promedio fue de 455 g, que permitió un peso de incorporación a la reproducción de 286 kg, a los 24 meses. El intervalo incorporación-cubrición promedio fue de 43 días.

    The purpose of this study was to evaluate, on a longitudinal basis, changes in maxillary and mandibular arch length over a 45-year period. Subjects were drawn from two pools of normal individuals. Twenty-eight male and 33 female infants were evaluated longitudinally at 6 weeks, 1 year, and 2 years (before the eruption of the deciduous dentition). Fifteen males and 15 females from the Iowa Facial Growth Study were evaluated at 3, 5, 8, 13, 26, and 45 years. Arch length measurements were obtained independently by two investigators. Intra- and interexaminer reliabilities were predetermined at 0.25 and 0.5 mm, respectively. The greatest incremental increases occurred during the first two years of life. Arch length continued to increase until 13 years in the maxillary arch, and until 8 in the mandibular. Then significant and consistent decreases occurred in both arches mesial to the permanent first molars.

    To determine the differential efficacy and safety of twice-weekly administration of 3 RDAs of iron and folic acid, with and without a complement of 2 RDAs of 11, and 1 RDA of 3 additional essential micronutrients as compared to a placebo control (PlbCON) given as foodLETs. A total of 250 children aged 6-24 months were enrolled after recruitment by village health workers; 19 of them dropped out during the trial. Children were assigned to one of three treatment arms and followed for 20.5 weeks; 41 supervised twice-weekly dosings of 30 mg of iron plus folic acid, either with or without accompanying micronutrients or placebo were given as foodLETs, a tool for ready-to-eat fortification in infant food. Initial and final measurements of anthropometry and blood biomarkers for hematological, iron stores and inflammatory status, as well as for abnormal hemoglobin (Hb), were obtained. Symptoms of listlessness, vomiting, watery stools and acute respiratory infections were monitored weekly. Iron-containing supplements increased Hb concentrations significantly (P<0.0001) and virtually eradicated any IDA, as compared to no change in hematological status in the PlbCON group (P=0.011). Iron stores, as reflected by ferritin, increased significantly with iron-containing treatments (P<0.0001). Responses were as effective in individuals with HbE as in those with exclusively HbA phenotypes. Watery stools (P=0.002) and listlessness (P=0.001) were significantly more frequent in those receiving iron and folic acid alone than in the PlbCON group. In contrast, acute respiratory infections (P=0.014) and listlessness (P=0.001) were significantly less frequent in those receiving the multiple micronutrient formulation than in the PlbCON group. Supplementation of micronutrients along with iron and folic acid mitigates the excess morbidity of iron-folate alone, without reducing its efficacy in correcting anemia and building iron stores. FoodLETs are a suitable vehicle to provide micronutrient

    The compressional and shear wave velocities for coesite have been measured simultaneously up to 5.8 GPa and 1073 K by ultrasonic interferometry for the first time. The shear wave velocity decreases with pressure along all isotherms. The resulting contrasts between coesite and stishovite reach 34% and 45% for P and S wave velocities, respectively, and 64% and 75% for their impedance at mantle conditions. The large velocity and impedance contrasts across coesite-stishovite transition imply that to generate the velocity and impedance contrasts observed at the X-discontinuity, only a small amount of silica would be required. The velocity jump dependences on silica, d(lnVP)/d(SiO2) = 0.38 (wt %)-1 and d(lnVS)/d(SiO2) = 0.52 (wt %)-1, are utilized to place constraints on the amount of silica in the upper mantle and provide a geophysical approach to track mantle eclogite materials and ancient subducted oceanic slabs.

    N-channel operation of thin-film transistors based on 1,4,5,8-naphthalene tetracarboxylic dianhydride (NTCDA) with a 9-nm-thick poly(methyl methacrylate) (PMMA) gate buffer layer was examined. The uniform coverage of the ultrathin PMMA layer on an SiO 2 gate insulator, verified by X-ray reflectivity measurement, caused the increase of electron field-effect mobility because of the suppression of electron traps existing on the SiO 2 surface. In addition, air stability for n-channel operation of the NTCDA transistor was also improved by the PMMA layer which possibly prevented the adsorption of ambient water molecules onto the SiO 2 surface.

    Full Text Available Background: Topotecan is the standard second line agent used in relapsed small cell lung cancer (SCLC. However, the erratic availability and the cost of the drug has been a prohibitive factor for its use in second-line setting in India. Paclitaxel has shown antitumor activity in heavily pretreated patients with SCLC. Hence, this audit was performed to study the efficacy of weekly paclitaxel as a form of metronomic therapy in the second-line setting in SCLC. Materials and Methods: Fifty-seven patients of relapsed SCLC who presented to the thoracic medical oncology unit of Tata Memorial Centre, Mumbai between January 2011 and December 2015 were selected for this analysis. Weekly paclitaxel at a dose of 80 mg/m 2 was administered until progression or development of intolerable side effects or patient refusal. Data regarding baseline demographics, previous treatment history, response rate, progression-free survival, overall survival (OS, and toxicity to weekly paclitaxel was extracted from a prospectively maintained database in the thoracic medical oncology unit and was analyzed using SPSS version 16 (IBM, New York, USA.

    Full Text Available A bone-remodeling imbalance induced by increased bone resorption and osteoclast formation causes skeletal diseases such as osteoporosis. Induction of osteogenic differentiation of bone marrow stromal cells (BMSCs leads to bone regeneration. Many researchers have tried to develop new adjuvants as specific stimulators of bone regeneration for therapeutic use in patients with bone resorption. We tried to develop a new adjuvant that has stronger osteogenic differentiation-promoting activity than bone morphogenetic proteins (BMPs. In this study, we identified a new peptide, which we called bone-forming peptide (BFP-3, derived from the immature precursor of BMP-7. Upon osteogenic differentiation, BMSCs treated with BFP-3 exhibited higher alkaline phosphatase (ALP activity and mineralization ability and significantly up-regulated expression of osteogenic genes such as ALP, osteocalcin (OC, Osterix, and Runx2 compared with control BMSCs. Furthermore, fluorescence-activated cell sorting (FACS and immunofluorescence analyses demonstrated that BFP-3 treatment up-regulated CD44 expression. Interestingly, extracellular signal-regulated kinase 1/2 (ERK1/2 and Smad1/5/8 phosphorylation was increased by BFP-3 treatment during osteogenic differentiation. Furthermore, BFP-3-induced osteogenic differentiation was significantly decreased by treatment with ERK1/2- and Smad-specific inhibitors. These results suggest that BFP-3 plays an important role in regulating osteogenic differentiation of BMSCs through increasing levels of osteogenic-inducing factors and regulating the ERK1/2 and Smad1/5/8 signaling pathways. Our finding indicates that BFP-3 may be a potential new therapeutic target for promoting bone formation.

    The 3 Sep 2016 M­­w5.8 Pawnee, Oklahoma earthquake was the largest event to occur in recorded history of the state. Widespread shaking from the event was felt in seven central U.S. states and caused damage as far away as Oklahoma City ( 115 km SSW). The Pawnee earthquake occurred soon after the deployment of a subsurface pore-fluid pressure monitoring network in Aug 2016. Eight pressure transducers were installed downhole in inactive saltwater disposal wells that were completed in the basal sedimentary zone (the Arbuckle Group). The transducers are located in Alfalfa, Grant, and Payne Counties at distances of 48 to 140 km from the Pawnee earthquake. We observed coseismic fluid pressure changes in all monitoring wells, indicating a large-scale poroelastic response in the Arbuckle. Two wells in Payne County lie in a zone of volumetric compression 48-52 km SSE of the rupture and experienced a co-seismic rise in fluid pressures that we conclude was related to poroelastic rebound of the Arbuckle reservoir. We compare measurements of the pore-fluid pressure change to estimated values given by the product of the volumetric strain, a Skempton's coefficient of 0.33, and a Bulk modulus of 25 GPa for fractured granitic basement rocks. We explore the possibility that the small increase in pore-fluid pressure may increase the rate of seismicity in regions outside of the mainshock region. We test this hypothesis by supplementing the Oklahoma Geological Survey earthquake catalog by semi-automated detection smaller magnitude (<2.6 M) earthquakes on seismic stations that are located in the vicinity of the wells. Using the events that occur in the week before the mainshock (27 Aug to 3 Sep 2016) as the background seismicity rate and the estimated pore-fluid pressure increase, we use a rate-state model to predict the seismicity rate change in the week following the event. We then compare the model predictions to the observed seismicity in the week following the Pawnee earthquake

    2014-01-01

    Current ringing in an Inductive Pulsed Plasma Thruster (IPPT) can lead to reduced energy efficiency, excess heating, and wear on circuit components such as capacitors and solid state devices. Clamping off the current using a fast turn-off power diode is an effective way to reduce current ringing and increase energy efficiency. A diode with a shorter reverse recovery time will allow the least amount of current to ring back through the circuit, as well as minimize switching losses. The reverse recovery response of a new 5.8 kilovolt SiC PiN diode from Cree, Inc. in the IPPT plasma drive circuit is investigated using a physicsbased Simulink model, and compared with that of a 5SDF 02D6004 5.5 kilovolt fast-switching Si diode from ABB. Parameter extraction was carried out for each diode using both datasheet specifications and experimental waveforms, in order to most accurately adapt the model to the specific device. Further experimental data will be discussed using a flat-plate IPPT developed at NASA Marshall Space Flight Center and used to verify the simulation results. A final quantitative measure of circuit efficiency will be described for both the Si and SiC diode configuration.

    Double-stranded M13 phage DNA (M13 mp10 replicative form) was photoreacted with 4'-hydroxymethyl-4,5',8-trimethylpsoralen, using light of wavelength greater than 320 nm or greater than 390 nm to generate predominantly crosslinks or monoadducts, respectively. The damaged DNAs were scored for inactivation and mutagenesis after transfection into Escherichia coli. The appearance of light-blue or colorless plaques on indicator medium showed that mutation had occurred in the lac insert of the viral DNA. A comparison of the consequences of the two phototreatments with psoralen supports the idea that crosslinks are both more lethal and more mutagenic than monoadducts. Numerous mutant clones partially or totally deficient in beta-galactosidase were plaque-purified and amplified. The viral DNA of each clone was sequenced by the dideoxy chain-terminating procedure. All of the observed base-pair changes were mapped to the lac promoter region and consisted of 3 transition, 14 transversion, and 6 single base-pair frame-shift mutations. The predominant mutation was a T.A----G.C transversion

    We have previously shown that the PLAG1 gene on chromosome 8q12 is consistently rearranged in pleomorphic adenomas of the salivary glands with t(3;8)(p21;q12) translocations. The t(3;8) results in promoter swapping between the PLAG1 gene, which encodes a novel zinc finger protein, and the constitutively expressed gene for beta-catenin (CTNNB1), a protein with roles in cell-cell adhesion and the WG/WNT signalling pathway. In order to assess the importance of other translocation partner genes of PLAG1, and their possible relationship to CTNNB1, we have characterized a second recurrent translocation, i.e. the t(5;8)(p13;q12). This translocation leads to ectopic expression of a chimeric transcript consisting of sequences from the ubiquitously expressed gene for the leukemia inhibitory factor receptor (LIFR) and PLAG1. As for the t(3;8), the fusions occurred in the 5'-noncoding regions of both genes, exchanging regulatory control elements while preserving the coding sequences. The results of the current as well as previous studies indicate that ectopic expression of PLAG1 under the control of promoters of distinct translocation partner genes is a general pathogenetic mechanism for pleomorphic adenomas with 8q12 aberrations.

    There is widespread concern about young girls displaying 'grown up' or sexualized behaviours, as well as experiencing body image and appearance concerns that were previously thought to only impact much older girls. The present study examined the influence of three maternal attributes, self-objectification, materialism and parenting style, on sexualized behaviours and appearance concerns in young girls. A sample of 252 Australian mothers of 5-8year old girls reported on the behaviours and appearance concerns observed in their daughters and also completed measures of their own self-objectification, materialism and parenting style. It was found that a significant proportion of young girls were engaging with 'teen' culture, using beauty products and expressing some degree of appearance concern. Maternal self-objectification was related to daughters' engagement in teen culture, use of beauty products and appearance concern. Maternal materialism was related to girls' engagement in teen culture and appearance concern, while an authoritative parenting style was negatively related to girls' use of beauty products. The findings suggest that maternal self-objectification and materialism play a role in the body image and appearance concerns of young girls, and in so doing, identify these maternal attributes as novel potential targets for intervention.

    High sensitivity and specificity of molecular biology techniques have proven usefulness for the detection, identification and typing of different pathogens. The ITS (Internal Transcribed Spacer) regions of the ribosomal DNA are highly conserved non-coding regions, and have been widely used in different studies including the determination of the genetic diversity of human fungal pathogens. This article wants to contribute to the understanding of the intra- and interspecific genetic diversity of isolates of the Histoplasma capsulatum and Sporothrix schenckii species complexes by an analysis of the available sequences of the ITS regions from different sequence databases. ITS1-5.8S-ITS2 sequences of each fungus, either deposited in GenBank, or from our research groups (registered in the Fungi Barcode of Life Database), were analyzed using the maximum likelihood (ML) method. ML analysis of the ITS sequences discriminated isolates from distant geographic origins and particular wild hosts, depending on the fungal species analyzed. This manuscript is part of the series of works presented at the "V International Workshop: Molecular genetic approaches to the study of human pathogenic fungi" (Oaxaca, Mexico, 2012).

    Abstract The Buffelgrass (Cenchrus ciliaris L., Poaceae) is one of the most important pasturage grasses due to its high productivity and good forage qualities. This species possess a high adaptability to bioclimatic constraints of arid zones and may be used for the restoration of degraded arid ecosystems. Tunisian populations present three ploidy levels (4x, 5x and 6x) with a basic chromosome number x=9. This study reported for the first time the distribution of the ribosomal genes (rRNA) for pentaploid and hexaploid cytotypes of Cenchrus ciliaris. Molecular cytogenetic study using double fluorescence in situ hybridization has shown that the two rDNA families, 5S and 18S-5.8S-26S (18S), displayed intraspecific variation in number of loci among different ploidy levels. Each ploidy level was characterized by specific number of both 5S and 18S rDNA loci (two loci in tetraploid, five in pentaploid and six in hexaploid level). For three studied cytotypes (4x, 5x and 6x) all 5S rDNA loci were localized on the subcentromeric region of chromosomes, while 18S loci were situated on the telomeric region of short chromosome arms. Data of the FISH experiments show proportional increase of ribosomal loci number during polyploidization processes. PMID:24260668

    The anti pp elastic differential cross section at 30 GeV/c incident momentum has been measured in a two-arm spectrometer experiment (WA7) at the CERN SPS. The vertical stroketvertical stroke-range covered extends from 0.5 to 5.8 (GeV/c)/sup 2/. A pronounced dip-bump structure is observed, with a sharp minimum around vertical stroketvertical strokeapprox.=1.7 (GeV/c)/sup 2/. The results are compared with existing anti pp data at lower energies and with our earlier anti pp data at 50 GeV/c. A number of model predictions are discussed. We also compare the anti pp 30 GeV/c differential cross section with that of pp at the same momentum. Finally, the energy dependence of the anti pp fixed-vertical stroketvertical stroke differential cross section in the incident momentum range 3.6 to 50 GeV/c is presented.

    Full Text Available The title complex, [Mn2(C18H4O10(H2O4]n, was synthesized from manganese(II chloride tetrahydrate and 9,10-dioxo-9,10-dihydroanthracene-1,4,5,8-tetracarboxylic acid (H4AQTC in water. The anthraquinone unit is located about a crystallographic center of inversion. Each asymmetric unit therefore contains one MnII atom, two water ligands and one half AQTC4− anion. The MnII atom is coordinated in a distorted octahedral geometry by four O atoms from three AQTC4− ligands and two water O atoms. Two of the carboxylate groups coordinate one MnII atom in a chelating mode, whereas the others each coordinate two MnII atoms. Each AQTC4− tetra-anion therefore coordinates six different MnII ions and, as a result, a three-dimensional coordination polymer is formed. O—H...O hydrogen bonds, some of them bifurcated, between water ligands and neighboring water or anthraquinone ligands are observed in the crystal structure.

    The synthesis is described of four oligo(gamma-glutamyl) conjugates of N10-propargyl-5,8-dideazafolic acid containing a total of two, three, four, and five L-glutamic acid residues. The tert-butyl group was chosen as the carboxyl protecting group in order to obviate the use of alkali and thus the possibility of gamma----alpha transpeptidation. The starting material, di-tert-butyl glutamate, was coupled to N-(benzyloxycarbonyl)-L-glutamic acid alpha-tert-butyl ester via a mixed anhydride with isobutyl chloroformate. Hydrogenolysis of the benzyloxycarbonyl group in the product gave a carboxyl-protected diglutamate, which either was acylated with 4-[(benzyloxycarbonyl)amino] benzoyl chloride to give a protected aminobenzamide or was cycled further by using the above mixed anhydride/hydrogenolysis sequence into tri-, tetra-, and pentaglutamates. Each of the last named was also acylated, as above, to give a benzamide. The benzyloxycarbonyl group in the benzamides was removed by hydrogenolysis and the amino groups thus exposed were N-alkylated with propargyl bromide. The resulting proparglyamines were further alkylated with 2-amino-6-(bromomethyl)-4-hydroxyquinazoline hydrobromide to give the antifolate poly(t-Bu) esters. Deprotection with trifluoroacetic acid in the final step delivered the desired antifolates as their trifluoroacetate salts. The di- to pentaglutamates were, respectively, 31-, 97-, 171-, and 167-fold more inhibitory to WI-L2 human thymidylate synthase than the parent compound.

    Vertical one-dimensional shear wave velocity (Vs) profiles are presented for 25 strong-motion instrument sites along the Mid-Atlantic eastern seaboard, Piedmont region, and Appalachian region, which surround the epicenter of the M5.8 Mineral, Virginia, Earthquake of August 23, 2011. Testing was performed at sites in Pennsylvania, Maryland, West Virginia, Virginia, the District of Columbia, North Carolina, and Tennessee. The purpose of the study is to determine the detailed site velocity profile, the average velocity in the upper 30 meters of the profile (VS,30), the average velocity for the entire profile (VS,Z), and the National Earthquake Hazards Reduction Program (NEHRP) site classification. The Vs profiles are estimated using a non-invasive continuous-sine-wave method for gathering the dispersion characteristics of surface waves. A large trailer-mounted active source was used to shake the ground during the testing and produce the surface waves. Shear wave velocity profiles were inverted from the averaged dispersion curves using three independent methods for comparison, and the root-mean square combined coefficient of variation (COV) of the dispersion and inversion calculations are estimated for each site.

    Purpose: Fractionated external beam radiotherapy (EBRT) ± carmustine (BCNU) is the standard of care for patients with glioblastoma multiforme (GBM), but survival results remain poor. Preclinical studies indicate synergy between RT and paclitaxel (TAX) in astrocytoma cell lines. Phase I studies in GBM have demonstrated a maximum tolerated dose for TAX of 225 mg/m 2 /3 h/week x 6, during EBRT, with no exacerbation of typical RT-induced toxicities. The Radiation Therapy Oncology Group (RTOG) therefore mounted a Phase II study to determine the feasibility and efficacy of conventional EBRT and concurrent weekly TAX at its MTD. Patients and Methods: Sixty-two patients with histologic diagnosis of GBM were enrolled from 8/16/96 through 3/21/97 in a multi-institutional Phase II trial of EBRT and TAX 225 mg/m 2 /3 h (1-3 h before EBRT), administered the first treatment day of each RT week. Total EBRT dose was 60 Gy (200 cGy/fraction), 5 days per week. A smaller treatment field, to include gross disease plus a margin only, was used after 46 Gy. Results: Sixty-one patients (98%) were evaluable. Median age was 55 years (range, 28-78). Seventy-four percent were ≥50 years. Recursive partitioning analysis (RPA) Classes III, IV, V, VI included 10 (17%), 21 (34%), 25 (41%), and 5 (8%) patients, respectively. Gross total resection was performed in only 16%. There was no Grade 3 or 4 neutropenia or thrombocytopenia. Hypersensitivity reactions precluding further use of TAX occurred in 4 patients. There were 2 instances of late neurotoxicity (4% Grade 3 or 4). Ninety-one percent of patients received treatment per protocol. Seventy-seven percent completed prescribed treatment (6 weeks). Of 35 patients with measurable disease, CR/PR was observed in 23%, MR in 17%, and SD in 43%. Seventeen percent demonstrated progression at first follow-up. Median potential follow-up time is 20 months. Median survival is 9.7 months, with median survivals for RPA classes III, IV, V, and VI of 16.3, 10

    Clinical, gross, and histopathology lesions and molecular characterization of Trichomonas spp. infection were described in two striped owls (Asio (Rhinoptynx) clamator), one American kestrel (Falco sparverius), two green-winged saltators (Saltator similis), and in a toco toucan (Ramphastos toco) from Brazil. These birds presented clinical signs including emaciation, ruffled feathers, abundant salivation and open mouth breathing presumably due to abundant caseous material. Gross lesions were characterized by multifocal yellow friable plaques on the surface of the tongue, pharynx and/or caseous masses partially occluding the laryngeal entrance. In the owls, the caseous material extended into the mandibular muscles and invaded the sinuses of the skull. Histopathologically, marked necrotic and inflammatory lesions were associated with numerous round to oval, pale eosinophilic structures (6-10μm) with basophilic nuclei, consistent with trichomonads. Organisms similar to those described above also were found in the liver of the two green-winged saltators. To the authors' knowledge, this is the first report of trichomonosis in a striped owl and a toco toucan. Sequence analysis of the Trichomonas spp. internal transcribed spacer 1 (ITS-1) region and partial 5.8S of the ribosomal RNA (rRNA) disclosed significant genetic diversity. Two sequences had 100% identity to Trichomonas gallinae, whereas two sequences had a 99% and 92% identity to a Trichomonas vaginalis-like sequence, respectively. One sequence (green-winged saltator 502-08) had a 100% identity to a newly recognized genus Simplicomonas. Copyright © 2012 Elsevier B.V. All rights reserved.

    Plasmodium parasites degrade hemoglobin producing reactive oxygen species as toxic byproducts which are detoxified by a series of antioxidant mechanisms. Quinoline compounds have demonstrated activity against hemoglobin degradation with 5,8-dimethylthieno[2,3-b]quinoline-2-carboxylic acid (TQCA) representing a recent compound inhibiting this process. Thus, this study was undertaken to determine the ability of TQCA to modify the oxidative status in Plasmodium berghei-infected erythrocytes. After hemolysis, activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR) and dehydrogenase enzymes as well as lipid peroxidation were investigated by spectrophotometry. Saturated and unsaturated fatty acids were determined by gas-liquid chromatography and the in vivo effects of TQCA were confirmed by a malaria murine model (Rane test). The activity of glucose-6-phosphate dehydrogenase (G6PDH) and 6-phosphogluconate dehydrogenase (6PGDH) in infected cells was diminished by this compound compared to control infection in 75.1 ± 3.5% and 26.5 ± 0.3%, respectively, while that of GPx and GR was also lowered (p quinoline derivate in 49.2 ± 1.32% and 37 ± 0.06%, respectively, protecting the cells from hemolysis caused by the infection. The in vitro results were in concordance with the potential in vivo activity of this compound in an established malaria murine model in which TQCA showed significant decrease in the parasitemia levels and increased the mean survival days of infected mice. In conclusion, the antioxidant defense represents a biochemical target for TQCA actions as a potent antimalarial whose effects were also confirmed in vivo. Copyright © 2015 Elsevier Inc.

    Ultrawideband (UWB) antennas, as core devices in high-speed wireless communication, are widely applied to mobile handsets, wireless sensor networks, and Internet of Things (IoT). A compact printed monopole antenna for UWB applications with triple band-notched characteristics is proposed in this paper. The antenna has a very compact size of 10 x 16 mm2 and is composed of a square slotted radiation patch and a narrow rectangular ground plane on the back of the substrate. First, by etching a pair of inverted T-shaped slots at the bottom of the radiation patch, one notched band at 5-6 GHz for rejecting the Wireless Local Area Network (WLAN) is generated. Then, by cutting a comb-shaped slot on the top of the radiation patch, a second notched band for rejecting 3.5 GHz Worldwide Interoperability for Microwave Access (WiMAX) is obtained. Further, by cutting a pair of rectangular slots and a C-shaped slot as well as adding a pair of small square parasitic patches at the center of the radiating patch, two separate notched bands for rejecting 5.2 GHz lower WLAN and 5.8 GHz upper WLAN are realized, respectively. Additionally, by integrating the slotted radiation patch with the narrow rectangular ground plane, an enhanced impedance bandwidth can be achieved, especially at the higher band. The antenna consists of linear symmetrical sections only and is easy for fabrication and fine-tuning. The measured results show that the designed antenna provides a wide impedance bandwidth of 150% from 2.12 to 14.80 GHz for VSWR antenna exhibits nearly omnidirectional radiation characteristics, low gain at the stopbands, and flat group delay over the whole UWB except at the stopbands. Simulated and experimental results show that the proposed antenna can provide good frequency-domain and time-domain performances at desired UWB frequencies and be an attractive candidate for portable IoT applications.

    Full Text Available Genes coding for 45S ribosomal RNA are organized in tandem arrays of up to several thousand copies and contain 18S, 5.8S and 26S rRNA units separated by internal transcribed spacers ITS1 and ITS2. While the rRNA units are evolutionary conserved, ITS show high level of interspecific divergence and have been used frequently in genetic diversity and phylogenetic studies. In this work we report on the structure and diversity of the ITS region in 87 representatives of the family Musaceae. We provide the first detailed information on ITS sequence diversity in the genus Musa and describe the presence of more than one type of ITS sequence within individual species. Both Sanger sequencing of amplified ITS regions and whole genome 454 sequencing lead to similar phylogenetic inferences. We show that it is necessary to identify putative pseudogenic ITS sequences, which may have negative effect on phylogenetic reconstruction at lower taxonomic levels. Phylogenetic reconstruction based on ITS sequence showed that the genus Musa is divided into two distinct clades--Callimusa and Australimusa and Eumusa and Rhodochlamys. Most of the intraspecific banana hybrids analyzed contain conserved parental ITS sequences, indicating incomplete concerted evolution of rDNA loci. Independent evolution of parental rDNA in hybrids enables determination of genomic constitution of hybrids using ITS. The observation of only one type of ITS sequence in some of the presumed interspecific hybrid clones warrants further study to confirm their hybrid origin and to unravel processes leading to evolution of their genomes.

    A series of trinuclear Ln 3 complexes (Ln III = Yb (1), Er (2), Dy (3) and Gd (4)) were prepared from the tris-chelate bidentate ligand 1,4,5,8,9,12-hexaazatriphenylene (HAT). 1 and 2 exhibited field-induced single-molecule-magnet (SMM) behavior with estimated U eff values of 21.30 and 13.86 K, respectively. Complex 3 behaved as a SMM even at zero field, and two different thermally assisted relaxation processes were detected with U eff values of 29.6 K (fast relaxation process, FR) and 69 K (slow relaxation process, SR) due to the existence of two magnetically different Dy III centers in the molecule. Ab initio studies reveal that all the Dy 3+ centers have almost an Ising ground state. The local anisotropy axes are not coplanar but form angles with the Dy3 plane in the range 58-78°. The magnetic interaction between the anisotropic Dy 3+ ions is antiferromagnetic in nature and very weak in magnitude. However, due to the extreme feebleness of the magnetic interaction with regard to the local excitation energies, the magnetization blockade is most probably of single-ion origin. Calculations support the existence of two relaxation processes, which take place through the first excited state following an Orbach/Raman mechanism. Finally, for complex 4, the magnetocaloric effect was simulated using the magnetic parameters extracted from the fit of the magnetization and susceptibility data and demonstrated that the simulated -ΔS m values were almost coincident with those extracted from the integration of the field dependence of the magnetization. The simulated MCE value at 2 K and 5 T (20.46 J kg -1 K -1 ) makes complex 4 an attractive candidate for cryogenic magnetization.

    This study compared the accuracy of ultrasound cervical assessment (cervical length and cervical index) and digital examination (Bishop score and cervical score) in the prediction of spontaneous birth before 34 weeks in twin pregnancies. In a prospective multicenter study, digital examination and transvaginal sonography were performed consecutively in twin pregnancies attending for routine sonography at either 22 weeks (175 women) or 27 weeks (153 women). The digital examination took place first, and the Bishop score and cervical score (cervical length minus cervical dilatation) were calculated. Ultrasound measurements were then made of cervical length and funnel length to yield the cervical index (1 + funnel length/cervical length). The association between each variable and delivery before 34 weeks was tested by the Mann-Whitney U-test. The receiver-operating characteristics (ROC) curves of the ultrasound and digital indicators were determined for both gestational age periods, and the areas under the ROC curves compared. The best cut-off values for each indicator were used to determine predictive values for delivery before 34 weeks. The median gestational age at delivery among the women included in the 22-week examination period was 36.0 (range, 21-40) weeks; 10.9% (19) gave birth spontaneously before 34 weeks. The median cervical length was 40 (range, 6-65) mm. All four parameters were predictors of delivery before 34 weeks. The areas under the ROC curves for cervical index, cervical length, Bishop score and cervical score did not differ significantly. The median gestational age at delivery among the women in the 27-week examination period was 36.0 (range, 27-40) weeks; 9.2% (14) gave birth spontaneously before 34 weeks. The median cervical length was 35 (range, 1-57) mm. All parameters except the Bishop score were predictors of delivery before 34 weeks.

    The Mw5.8 Pawnee, Oklahoma earthquake occurred on 03 September 2016 (07:02:44 local time; depth 5.6 km) in a rural, sparsely populated area. The USGS, Mw-phase moment tensor indicated slip occurred on a sub-vertical fault plane, striking WNW or NNE. Relocations of this mainshock and a dozen aftershocks (Mw 2.5-3.6) in the day following the event were broadly aligned along a WNW trend. These data, along with USGS `Did You Feel It?' and ShakeMap products, helped guide our field response. Our team arrived to the epicentral region 10 hours after the mainshock and spent the next 1.5 days examining 60 km of paved and dirt roads across a 40 km2 area for evidence of surface deformation, liquefaction, and structural damage. We completed a 2 km-long, NNE transect on foot centered on the epicenter, perpendicular to the suspected WNW-striking source fault. No surface rupture was observed during our reconnaissance surveys. We interviewed 10 residents within a 1-6 km radius of the epicenter, who reported up to 30 seconds of shaking. Structural damage was common and ranged from minor to moderate. Failure and collapse of masonry chimneys and exterior house facades made of stone or brick was common near the epicenter, yet a few were undamaged. At several locations, damage patterns suggest an E-W shaking direction; for example, only the western wall of a century-old unreinforced brick storage building failed, elevated fuel tanks shook E-W, and most metal straps securing a trailer home to its cinder-block foundation were sheared in an E-W direction. One earthquake-related injury was caused by chimney bricks that struck a man on the head. Strong ground motion cracked foundations and interior walls at many homes near the epicenter. Minor ground settlement and ground cracking was observed in artificial fill surrounding houses and along the crests of small earthen dams. A large barn fire was attributed to the earthquake. Landowners reported sand blows in farm fields underlain by sandy

    The Mw 5.8 earthquake of 23 August 2011 (17:51:04 UTC) (moment, M0 5.7×1017  N·m) occurred near Mineral, Virginia, within the central Virginia seismic zone and was felt by more people than any other earthquake in United States history. The U.S. Geological Survey (USGS) received 148,638 felt reports from 31 states and 4 Canadian provinces. The USGS PAGER system estimates as many as 120,000 people were exposed to shaking intensity levels of IV and greater, with approximately 10,000 exposed to shaking as high as intensity VIII. Both regional and teleseismic moment tensor solutions characterize the earthquake as a northeast‐striking reverse fault that nucleated at a depth of approximately 7±2  km. The distribution of reported macroseismic intensities is roughly ten times the area of a similarly sized earthquake in the western United States (Horton and Williams, 2012). Near‐source and far‐field damage reports, which extend as far away as Washington, D.C., (135 km away) and Baltimore, Maryland, (200 km away) are consistent with an earthquake of this size and depth in the eastern United States (EUS). Within the first few days following the earthquake, several government and academic institutions installed 36 portable seismograph stations in the epicentral region, making this among the best‐recorded aftershock sequences in the EUS. Based on modeling of these data, we provide a detailed description of the source parameters of the mainshock and analysis of the subsequent aftershock sequence for defining the fault geometry, area of rupture, and observations of the aftershock sequence magnitude–frequency and temporal distribution. The observed slope of the magnitude–frequency curve or b‐value for the aftershock sequence is consistent with previous EUS studies (b=0.75), suggesting that most of the accumulated strain was released by the mainshock. The aftershocks define a rupture that extends between approximately 2–8 km in depth and 8–10 km along

    Sequence variability of the ITS spacers and 5.8S rRNA gene was examined in 11 accessions of the subfamily Scilloideae, including seven accessions of rare and endangered species Bellevalia sarmatica from Volgograd region. The intraspecific polymorphism level of the examined ITS1–5.8S–ITS2 sequence of B. sarmatica accessions constituted 1.3%. The phylogenetic position of B. sarmatica within the genus Bellevalia was determined. It was demonstrated that B. sarmatica belonged to the section Nutantes, and the most closely related species were B. webbiana and B. dubia. Nucleotide substitutions in the 5.8S rRNA gene sequence of the analyzed Scilloideae accessions were identified and studied. The predicted secondary structure of 5.8S rRNA gene was constructed. It was demonstrated that in the examined accessions, mutations in the 5.8S rRNA gene were mainly localized in the third hairpin region and had no effect on the secondary structure of the 5.8S rRNA molecule.

    Oppositional defiant disorder (ODD)is associated with a high degree of impairment in social skills, family interaction, and academic functioning. Comorbid ODD is reportedly present in 40% to 70% of children and adolescents with attention-deficit/hyperactivity disorder (ADHD). The goal of this study was to assess the efficacy and safety of mixed amphetamine salts extended release (MAS XR) for the treatment of ODD in children and adolescents aged 6 to 17 years. This was a 4-week, multicenter, randomized, double-blind, parallel-group, placebo-controlled, forced-dose-escalation study. Patients were randomized to receive active treatment with MAS XR 10, 20, 30, or 40 mg/d or placebo. The primary efficacy end point was the ODD subscale of the Swanson, Nolan, and Pelham-IV (SNAP-IV) parent rating. Primary safety measures included adverse events recorded at each visit and for 30 days after study drug discontinuation, and changes in vital signs, 12-lead electrocardiographic (ECG) findings, laboratory tests and physical examinations, and body weight. A post hoc efficacy reanalysis was completed based on the results for the per-protocol population. For this analysis, patients were divided into high and low baseline severity categories according to the dichotomized baseline ODD parent or teacher score or dichotomized baseline ADHD parent or teacher score (high defined as scores at the median or greater and low defined as scores less than the median). A total of 308 children and adolescents (age range, 6-17 years; 213 males, 95 females) were randomized to receive active treatment with MAS XR 10 mg/d (n = 60) 20 mg/d (n = 58), 30 mg/d (n = 69), or 40 mg/d (n = 61) or placebo (n = 60). Of the 308 study patients, 244 (79.2%) had comorbid ADHD. A significant change from baseline in the ODD symptoms measured with the SNAP-IV parent rating subscale was found for the MAS XR 30-mg/d (-0.52; P < 0.001) and 40-mg/d (-0.56; P = 0.002) groups in the per-protocol analysis and for the MAS XR

    The purpose of this study was to evaluate the clinical, radiographic, and patient-based outcomes of dental implants placed at an undergraduate student dental clinic. A retrospective study was performed to determine the success and survival rates of dental implants placed at the undergraduate dental clinic at Dalhousie University between January 1999 and January 2012. Only patients with a minimum of 1-year follow-up were included. Clinical and radiographic assessments determined implant success and survival rates. Questionnaires recorded patients' satisfaction with esthetics, comfort, and ease of hygiene. Of the 352 patients (n = 591 implants) who received implants over 13 years, 165 patients completed the clinical and radiographic examinations. By the end of the study period, demographic information and implant characteristics were collected for 111 (n = 217 implants; 47.5% in the maxilla, 52.6% in the mandible) of these patients. Of those assessed clinically, 36.4% were males and 63.6% females, with a mean age of 56.1 ± 14.15 years (range, 17 to 86 years) at the time of implant placement. The mean follow-up period was 5.8 years (range, 1 to 13 years). The overall implant success and survival rates were 88.0% and 97.2%, respectively. No observable bone loss was evident in 88.0% of the surviving implants. There were no implant fractures. Most patients (91.2%) were very satisfied with the implant restoration appearance, 88.0% were very comfortable with the implant, 92.6% were very satisfied with their ability to chew, and 84.8% reported easy hygiene maintenance at the implant sites. Implant success and survival in an undergraduate student clinic were comparable to those reported in the literature. It seems that inexperienced students were able to provide restorations that were very satisfying to the patients.

    To characterize risk of hypotension requiring admission to hospital in middle aged and older men treated with tamsulosin for benign prostatic hyperplasia. Population based retrospective cohort study (between patient methodology) and self controlled case series (within patient methodology). Healthcare claims data from the IMS Lifelink database in the United States. Men aged 40-85 years with private US healthcare insurance entering the cohort at their first dispensing for tamsulosin or for a 5α reductase inhibitor (5ARI) between January 2001 and June 2011 after a minimum of six months' enrolment. Hypotension requiring admission to hospital. Cox proportional hazards models estimated rate ratios at time varying intervals during follow-up: weeks 1-4, 5-8, and 9-12 after tamsulosin initiation; weeks 1-4, 5-8, and 9-12 after restarting tamsulosin (after a four week gap); and maintenance tamsulosin treatment (remaining exposed person time). Covariates included age, calendar year, demographics, antihypertensive use, healthcare use, and a Charlson comorbidity score. A self controlled case series, having implicit control for time invariant covariates, was additionally conducted. Among 383,567 new users of study drugs (tamsulosin 297,596; 5ARI 85,971), 2562 admissions to hospital for severe hypotension were identified. The incidence for hypotension was higher for tamsulosin (42.4 events per 10,000 person years) than for 5ARIs (31.3 events per 10,000 person years) or all accrued person time (29.1 events per 10,000 person years). After tamsulosin initiation, the cohort analysis identified an increased rate of hypotension during weeks 1-4 (rate ratio 2.12 (95% confidence interval 1.29 to 3.04)) and 5-8 (1.51 (1.04 to 2.18)), and no significant increase at weeks 9-12. The rate ratio for hypotension also increased at weeks 1-4 (1.84 (1.46 to 2.33)) and 5-8 (1.85 (1.45 to 2.36)) after restarting tamsulosin, as did maintenance tamsulosin treatment (1.19 (1.07 to 1.32)).

    Full Text Available History of present illness: A 35-year-old female presented to the ED with a Glasgow Coma Scale (GCS of 11. Per her boyfriend, the patient was having headaches for the past 3 weeks. She was initially taken to an outside hospital where her GCS was reported as 13. A non-contrast head computed tomography (CT revealed a large lobar intraparenchymal hemorrhage within the left frontal parietal lobe with midline shift. Upon examination, vitals were notable for blood pressure of 209/88mmHg, and her left pupil was fixed and dilated. The patient had extension of her right arm to noxious stimuli, paralysis of her right leg, and purposeful movement of the left arm and left leg. The patient was started on a nicardipine drip in the ED and subsequently taken to the operating room for a decompressive craniectomy. Significant findings: The patient’s head CT showed a significant area of hyperdensity consistent with an intracranial hemorrhage located within the left frontal parietal lobe (red arrow. Additionally, there is rightward midline shift up to 1.1cm (green arrow and entrapment of the right lateral ventricle (blue arrow. Discussion: Intraparenchymal hemorrhage (IPH is associated with high morbidity and mortality. Although the mortality for subarachnoid hemorrhage (SAH has declined steadily over the past several decades, the mortality for IPH mortality has not significantly.1 One of the most serious considerations when treating a patient with IPH is the management of intracranial pressure (ICP.2 Once an IPH is identified, immediate steps should be taken to bring ICP within acceptable levels including elevating the head of the bed to 30 degrees, sedation, and controlling hypertension with medications.2-3 Even with early and aggressive care, the prognosis for IPH remains poor; the 30-day mortality rate for IPH is estimated to be less than 50%, and a 2010 systematic review estimated only 12-39% of IPH patients achieve independent function.4-5 Predictors of

    Alves, AR, Marta, CC, Neiva, HP, Izquierdo, M, and Marques, MC. Concurrent training in prepubescent children: the effects of 8 weeks of strength and aerobic training on explosive strength and V[Combining Dot Above]O2max. J Strength Cond Res 30(7): 2019-2032, 2016-The purpose of this study was to compare the effects of 8-week training periods of strength training alone (GS), combined strength and aerobic training in the same session (GCOM1), or in 2 different sessions (GCOM2) on explosive strength and maximal oxygen uptake (V[Combining Dot Above]O2max) in prepubescent children. Of note, 168 healthy children, aged 10-11 years (10.9 ± 0.5), were randomly selected and assigned to 3 training groups to train twice a week for 8 weeks: GS (n = 41), GCOM1 (n = 45), GCOM2 (n = 38) groups, and a control group (GC) (n = 44; no training program). The GC maintained the baseline level, and trained-induced differences were found in the experimental groups. Differences were observed in the 1 and 3-kg medicine ball throws (GS: +5.8 and +8.1%, respectively; GCOM1: +5.7 and +8.7%, respectively; GCOM2: +6.2 and +8%, respectively, p training period induced gains in the 20-m time (GS: +2.1%; GCOM1: +2.1%; GCOM2: +2.3%, p concurrent training when it was performed in different sessions. These results suggest that concurrent training in 2 different sessions seems to be an effective and useful method for training-induced explosive strength and V[Combining Dot Above]O2max in prepubescent children. This could be considered as an alternative way to optimize explosive strength training and cardiorespiratory fitness in school-based programs.

    Clodronate is a bisphosphonate used for the treatment of postmenopausal osteoporosis and all conditions characterized by excess bone resorption. We have previously reported that intramuscular (IM) therapy with clodronate at a dose of 100 mg/week displays significant effects on bone mineral density (BMD) although a plateau effect is observed after 1 year of treatment. Previous reports indicate that the densitometric effects of bisphosphonates directly correlate with the drug dosage and suggest that using IM clodronate at doses higher than 100 mg/week may result in improved efficacy. However, to the best of our knowledge, this has never been proved. The primary endpoint of the study was the effect on BMD of IM clodronate 100 mg once weekly or 100 mg twice weekly in patients with postmenopausal osteoporosis. The incidence of non-traumatic vertebral fractures and adverse events was also reported. The present study was a randomized, open-label, parallel-group trial conducted between January 2007 and December 2009 in the Osteoporosis and Osteoarticular Instrumental Diagnosis Centre (University of Siena, Siena, Italy). The study involved 60 women, aged 57-78 years, with a history of postmenopausal osteoporosis for more than 5 years. Patients were randomized to receive IM clodronate 100 mg once weekly (Group A, 30 patients) or 100 mg twice weekly (Group B, 30 patients), for 2 years. Significant increases compared with baseline in BMD were observed for both groups at 1 and 2 years, with significantly higher increases for Group B compared with Group A. Group B displayed a BMD increase (± SD) at the lumbar spine of +4.0 % (± 2.1) and +5.9 % (± 2.0) at 1 and 2 year(s), respectively, compared with +2.8 % (± 1.7) and +3.5 % (± 2.2), respectively, observed for Group A. Similarly, Group B showed better performance compared with Group A for BMD increase at the femoral neck, with an observed increase of +3.5 % (± 1.7) and +5.4 % (± 1.8) at 1 and 2 year(s), respectively

    To establish normal ranges of maternal serum thyroid-stimulating hormone (TSH), free thyroxine (FT4) and free triiodothyronine (FT3) at 11-13 weeks of gestation. Maternal serum concentrations of FT3, FT4, TSH, anti-thyroperoxidase (anti-TPO) and anti-thyroglobulin (anti-Tg) antibodies were measured at 11-13 weeks. Normal ranges were constructed from the data of singleton pregnancies with no anti-thyroid antibodies resulting in live births after 34 weeks of phenotypically normal neonates with birth weight above the 5th percentile. Adjustments were made for maternal characteristics found by multiple regression analysis to affect the levels of TSH, FT3 and FT4. 3,592 of the 4,318 pregnancies examined were antibody negative, and in this group serum TSH increased whereas FT3 and FT4 decreased with gestation, and all three were lower in black than in white women. Serum FT3 and FT4 decreased but TSH did not change significantly with maternal age; TSH and FT3 increased whereas FT4 decreased with body mass index; TSH decreased whereas FT3 and FT4 increased with serum free beta-hCG. In the antibody-positive group, compared to the negative group, median TSH was higher and median FT3 and FT4 were lower. The study established normal ranges for maternal thyroid function at 11-13 weeks. Copyright 2010 S. Karger AG, Basel.

    To determine the benefit of a 4-week incubation for mycology cultures, we evaluated all positive cultures during the fourth week of incubation in a 1-year period. Of 3,855 positive mycology cultures (yeast, 82%; molds, 18%), 62 (1.6%) were positive during the fourth week (yeast, 42%; molds, 58%). Only 15 of the 62 cultures (24%) were considered clinically relevant (2 isolates from invasive fungal infection and 13 isolates from cutaneous mycosis). With the exception of those from skin samples, isolates recovered during the fourth week are rarely important for patient care. PMID:9817896

    2015-01-01

    We aimed to investigate whether conservative management of preterm premature rupture of membranes (PPROM) at 32-34 weeks' gestation improves outcome. In this retrospective analysis of singleton pregnancies, the study group included patients with PPROM at 28-34 weeks' gestation and the control group included patients presented with spontaneous preterm delivery at 28-34 weeks' gestation. Both groups were subdivided according to gestational age - early (28-31 weeks' gestation) versus late (32-34 weeks' gestation). Adverse neonatal outcome included neonatal death, intraventricular haemorrhage grade 3/4, respiratory distress syndrome, periventricular leucomalacia and neonatal sepsis. The study and control groups included 94 and 86 women, respectively. The study group had a lower incidence of adverse neonatal outcome at the earlier weeks (28-31), compared with the control group at the same gestational age. In contrast, at 32-34 weeks' gestation no difference in the risk for adverse neonatal outcome was noticed. Additionally, within the study group, chorioamnionitis rate was significantly higher among those who delivered at 32-34 weeks' gestation (p < 0.01). No advantage for conservative management of PPROM was demonstrated beyond 31 weeks' gestation. Moreover, conservative management of PPROM at 32-34 weeks' gestation may expose both mother and neonate to infectious morbidity.

    The purpose of this study was to determine the effects of a 12-week strength training program on movement time (MT) on fencers of national level. Twelve male fencers were randomly divided into 2 groups: the control group (CG: N = 6; age, 22.3 ± 8.1 years) and the treatment group (TG: N = 6; age, 24.8 ± 7.2 years). The CG fencers followed the standard physical conditioning program, which was partially modified for the TG. The TG participated in a 12-week strength training program divided into 2 parts: maximal strength training, including weightlifting exercises (2 days a week for 6 weeks) and explosive strength training, with combined weights and plyometric exercises (2 days a week for 6 weeks). Body mass, body fat, muscle mass, jumping ability, maximal strength, reaction time, and MT were measured on 4 separate occasions. The TG demonstrated significant increases (p ≤ 0.05) in maximal strength and jumping ability after 6 weeks of training and in MT after 12 weeks. These improvements remained unaltered during the 4-week detraining period. It may be concluded that a 12-week strength training program can improve maximal and explosive strength, and these increases can be transferred to MT performance. However, fencers need time to transfer the gains.

  11. Intracorneal blood removal six weeks after canaloplasty

    Directory of Open Access Journals (Sweden)

    Alberto Rossetti

    2013-01-01

    Full Text Available In a 71-year-old patient with bilateral open-angle glaucoma, intracorneal blood was found after a canaloplasty procedure in the right eye. Six weeks after surgery on ultrasound biomicroscopy examination, liquified blood and blood clots could be observed nasally in the deep corneal stroma close to the Descemet′s membrane. The intracorneal blood was washed out with balanced saline solution following deep corneal incision and lamellar dissection. Descemet′s membrane was reattached with air injection into the anterior chamber. Two months later, visual acuity improved to 20/50, intraocular pressure was 16 mm Hg without medication and confocal microscopy showed deep stromal folds and limited endothelial cell loss. Viscoelastic entering the cornea at Schwalbe′s line and reflux of blood from the collector channels to Schlemm′s canal can account for corneal hematoma. Even six weeks after canaloplasty, successful blood removal could be fulfilled without rupturing the Descemet′s membrane.

    A study was conducted to determine the solar day, lunar day, and weekly rhythms in human copulatory behavior. The study subjects were young married couples, with a median age of 25, living in North Carolina. All avoided conception by means other than oral contraception (OC). The husband and wife were paid $1.00/day for completing a questionnaire each morning, reporting whether they had engaged in intercourse in the previous 24 hours. Subjects recorded copulatory events to the nearest hour. Discrepancies between report pairs on whether intercourse had occurred were less than 1%. The data presented are from 2 studies, 1 consisting of 48 couples, reporting 1230 copulations between September 3 and December 2, 1973, and the other of 30 couples, over 711 copulations recorded between June 8 and September 5, 1974. Only the women's responses are reported here; menses were ignored. The average copulation rate/couple was 2.48 times/week in the 1973 study and 2.34 times/week for the 1974 group. The extreme values were 7.4 times/week and 0.64 times/week. Combining all the data produced a mean rate of 2.44 copulations/week. Mean daily copulatory rates for both studies were so similar that the data were pooled into a single curve for presentation. The copulation rates on weekdays were very similar, with just under 1/3 of the sample copulating each day. The average daily rates increased to 40.3% on Saturdays and to 52.6% on Sundays. The rate on Friday differed significantly from Saturday and Saturday from Sunday. 38.3% of the week's copulations occurred on the weekend. On 10.6% of the days that couples copulated, they did so twice or (rarely) 3 times, in a single day. Single-couple multiple copulations were 3.4 times more common on Sundays than on a weekday and 1.6 times more common than on Saturdays. 61% in 1973 and 66% in 1974 of all weekday copulations took place between the hours of 10:00 p.m. and 1:00 a.m. For the weekend it was mainly the augmented copulation rates during

    Docetaxel-based chemotherapy will remain clinically relevant and many of our patients will continue to receive the drug. In a recent phase 2 study of docetaxel 35 mg/m2 (weekly) in patients with metastatic breast cancer, the incidence of grade 3 cutaneous toxicity is 19%. The skin toxicity observed consists of limb/palmar-plantar erythematous reactions, or fixed-plaque erythrodysesthesia. Case series or reports have reported varied manifestations of skin reactions and include erythema multiforme, nail changes (onycholysis, pigmentation, paronychia), scleroderma, supravenous discoloration, radiation recall dermatitis, and flagellate erythema. We would like to report four patients with cutaneous reactions resulting from weekly administration of docetaxel. All cases are heavily pre-treated patients, receiving docetaxel as second or third line therapy. The cutaneous reactions occur at cycle 5. The time between chemotherapy to development of skin lesions is from 1 to 7 days. Lesions usually resolve with desquamation leaving behind areas with hyper-pigmentation or hypo-pigmentation over a period of 2 to 3 weeks. The management strategies include hand elevation, warm or cold compresses, topical and/or systemic antibiotics, topical and/or systemic corticosteroids, and cessation of drug. There is a need for a systematic approach to manage these cutaneous reactions. Oncology trained pharmacists play vital roles in assessing, managing, documenting and patient education.

    A prospective single-center interventional cohort study was conducted to evaluate the effects of a 5-week comprehensive cardiac rehabilitation program on terms exercise capacity, quality of life, echocardiographic findings and autonomic modulation after first-time myocardial infarction. We studied 37 consecutive post-myocardial infartion patients (mean age 66 years). All patients began a 5-week cardiac rehabilitation supervised training. The exercise program consisted of 40 minutes of training, three times a week, on a cycle ergometer at 60-80% of the maximal heart rate. At baseline and after training program we analyzed: the distance walked after the Six-Minutes Walking Test (6MWT); quality of life (QoL) assesed using the Psychological General Well-Being Inventory (PGWBI) questionnaire; echocardiographic finding and autonomic balance assesed heart rate variability (HRV). We observed statistically significant improvement in exercise capacity (from 423±94 to 496±13 m; P<0.05). Also we observed statistically significant improvements in the many PGWBI dimensions; particularly, anxiety +5.8% (from 18.11±5.2 to 19.12±4.4); depression +6.0% (from 12.00±3.0 to 12.73±2.4); positive well-being +6% (from 11.55±3.5 to 12.23±4.0); general health +10.3% (from 9.48±3.5 to 10.46±2.87); vitality +6.8% (from 12.96±4.2 to 13.85±4.2). Finally, we observed changes in HRV indices after training program: RR (from 903±169 ms to 952±163 ms; P<0.05), pNN50% (from 4.74±4.89 to 6.23±5.53; P<0.05), in time-domain; LF (from 274±169 to 362±233 ms2; P<0,05); HF (from 214±154 to 314±194 ms2; P<0.05) and LF/HF (from 1.53±0.54 to 1.24±0.47; P<0.05) in frequency-domain. The study suggest that a cardiac rehabilitation program in postmyocardial infarction improves exercise capacity, QoL and autonomic modulation.

    To evaluate the long-term aesthetic outcome of the single crowns supported by soft tissue level implants placed in healed sites in the anterior maxilla region via the pink aesthetic score (PES) and the white aesthetic score (WES). According to the inclusion criteria, patients who had received a single Straumann(®) Standard Plus implant in the anterior maxilla at the Shanghai 9th People's Hospital between 2005 and 2008 were invited for a re-examination based on a number of inclusion criteria and exclusion criteria. Clinical, radiographic and aesthetic outcomes (PES/WES) were assessed during their revisit at 5-8 years after crown placement. Forty-five patients were enrolled in the study. All 45 implants were successfully integrated and most of the implants did not show signs of peri-implant disease at the time of the assessment. The marginal bone resorption was 1.10 ± 0.92 mm. The mean total PES was 8.48 ± 2.62 at the baseline, 9.57 ± 2.37 at the 6-10 months revisit and 9.01 ± 2.45 at the 5-8 years follow-up. The scores of the mesial and distal papillae increased significantly between the baseline and 6-10 months follow-up, this improvement remained stable at the 5-8 years follow-up. The scores of soft tissue level, colour of the soft tissue, soft tissue texture and the alveolar process decreased significantly between the 6-10 months and 5-8 years revisits. The mean WES was 7.83 ± 1.60 at the baseline and 7.72 ± 1.43 at the 5-8 years revisit. There was no significant difference of the WES between the baseline and 5-8 years revisit. The possibility of spontaneous papillae regeneration after implant treatment and the long-term stability of the regenerated papillae were confirmed. However, recession of the facial soft tissue has been found. The incidence of the recession at thin biotype sites tended to be higher. © 2014 John Wiley & Sons A/S.

    The purpose of this study was to determine the effects of an 18-week strength training program on variables related to low-handicap golfers' performance. Ten right-handed male golfers, reporting a handicap of 5 or less, were randomly divided into two groups: the control group (CG) (N = 5, age: 23.9 ± 6.7 years) and the treatment group (TG) (N = 5, age: 24.2 ± 5.4 years). CG players followed the standard physical conditioning program for golf, which was partially modified for the TG. The TG participated in an 18-week strength training program divided into three parts: maximal strength training including weightlifting exercises (2 days a week for 6 weeks), explosive strength training with combined weights and plyometric exercises (2 days a week for 6 weeks), and golf-specific strength training, including swings with a weighted club and accelerated swings with an acceleration tubing system (3 days a week for 6 weeks). Body mass, body fat, muscle mass, jumping ability, isometric grip strength, maximal strength (RM), ball speed, and golf club mean acceleration were measured on five separate occasions. The TG demonstrated significant increases (p strength after 6 weeks of training and in driving performance after 12 weeks. These improvements remained unaltered during the 6-week golf-specific training period and even during a 5-week detraining period. It may be concluded that an 18-week strength training program can improve maximal and explosive strength and these increases can be transferred to driving performance; however, golfers need time to transfer the gains.

    The study of sedentary behavior is a relatively new area in population health research, and little is known about patterns of sitting time on week-days and weekend-days. To compare self-reported week-day and weekend-day sitting time with reported weekly time spent in other activities. Data were from 8,717 women born between 1973 and 1978 ('younger'), and 10,490 women born between 1946 and 1951 ('mid-age') who completed surveys for the Australian Longitudinal Study on Women's Health in 2003 and 2001, respectively. They were asked about time spent sitting on week-days and weekend-days. The women were also asked to report time spent in employment, active leisure, passive leisure, home duties, and studying. Mean week-day and weekend-day sitting times were compared with time-use using analysis of variance. Younger women sat more than mid-aged women, and sitting time was higher on week-days than on weekend-days in both cohorts. There were marked positive associations between week-day and weekend-day sitting times and time spent in passive leisure in both cohorts, and with time spent studying on week-days for the younger women. Week-day sitting time was markedly higher in women who reported >35 h in employment, compared with those who worked day sitting time was higher than weekend-day sitting time, the patterns of the relationships between week-day and weekend-day sitting and time-use were largely similar, except for time spent in employment.

    A 12-week multi-team sport programme was provided to employees of a large services organisation and conducted in workplaces. This programme was used to investigate the short-term effect of regular sports team participation on individual employee and organisational health. A large services organisation participated in this study. Two regional worksites of office workers were assigned as the team sport (intervention) (n = 28 participants) or control (n = 20 participants) groups. The team sport sessions were underpinned by psychological behaviour change theory and consisted of weekly 1-h team sport sessions for 12 weeks. Measures of aerobic fitness, physical activity behaviour, group cohesion, interaction and communication, psychological wellbeing, health, anthropometrics and workplace experiences were recorded pre- and post-intervention. Data were analysed using a series of mixed ANOVAs. After 12 weeks significant improvements were observed in VO 2 max (+ 4.5 ± 5.8 ml/min kg, P intervention group. A significant (P intervention group. Participation in team sport may be an effective method to improve the aerobic fitness and physical activity behaviour of employees, and promote interpersonal communication between colleagues. Individual health outcomes and social interactions have the capacity to influence the health of the organisation. The extent of which these findings are replicable across a scope of organisations should be examined objectively over the long term.

    Full Text Available Cheese whey is a dairy industry waste have high lactose concentration, which case environmental problem. Therefore biofuel production from cheese whey become an interest as renewable energy. In this study 28 yeasts were isolated from Kenyan cheese whey and characterized for lactose fermentation. Out of them one isolate, designated as BM9 had high efficiency for lactose fermentation was selected. For genetically identification PCR amplification of both internal transcribed spacer (ITS and 5.8 rDNA region (ITS1-5.8S-ITS2 and the variable D1/D2 domain of the 26S rRNA gene were used. RFLP of the PCR-amplified ITS1-5.8S-ITS2 region (750 bp using two restriction enzymes HaeIII and HinfI yielded fragments with 650 + 80 bp and 250 + 190 + 120 + 80 bp respectively witch identified the isolate as Kluyveromyces marxianus. 26S rRNA of the isolate was sequenced and compared with known 26S rRNA sequences in the GenBank database. Results of 26S rRNA gene confirmed that the isolate was highly related to K. marxianus with similarity 99%. Phylogenetic analysis show that BM9 shared a one cluster with K. marxianus. The fermentative performance of the strain BM9 on cheese whey to produce bio-ethanol at different parameters such as incubation temperature, initial pH, whey sugar concentrations, and yeast concentrations was evaluated.

    Post-term pregnancy, a pregnancy exceeding 294 days or 42 completed weeks, is associated with increased perinatal morbidity and mortality and is considered a high-risk condition which requires specialist surveillance and induction of labour. However, there is uncertainty on the policy concerning the timing of induction for post-term pregnancy or impending post-term pregnancy, leading to practice variation between caregivers. Previous studies on induction at or beyond 41 weeks versus expectant management showed different results on perinatal outcome though conclusions in meta-analyses show a preference for induction at 41 weeks. However, interpretation of the results is hampered by the limited sample size of most trials and the heterogeneity in design. Most control groups had a policy of awaiting spontaneous onset of labour that went far beyond 42 weeks, which does not reflect usual care in The Netherlands where induction of labour at 42 weeks is the regular policy. Thus leaving the question unanswered if induction at 41 weeks results in better perinatal outcomes than expectant management until 42 weeks. In this study we compare a policy of labour induction at 41 + 0/+1 weeks with a policy of expectant management until 42 weeks in obstetrical low risk women without contra-indications for expectant management until 42 weeks and a singleton pregnancy in cephalic position. We will perform a multicenter randomised controlled clinical trial. Our primary outcome will be a composite outcome of perinatal mortality and neonatal morbidity. Secondary outcomes will be maternal outcomes as mode of delivery (operative vaginal delivery and Caesarean section), need for analgesia and postpartum haemorrhage (≥1000 ml). Maternal preferences, satisfaction, wellbeing, pain and anxiety will be assessed alongside the trial. This study will provide evidence for the management of pregnant women reaching a gestational age of 41 weeks. Dutch Trial Register (Nederlands Trial Register): NTR

    Full Text Available Randomized studies have shown that bortezomib (BTZ can be given weekly via intravenous (IV route or twice weekly via subcutaneous (SC route with lower neuropathy risk and no loss of anti-myeloma efficacy compared to original standard IV twice weekly schedule. Weekly SC should therefore yield the best therapeutic index and is widely used but has not been compared to established administration schedules in the context of a clinical trial.Comprehensive electronic medical record review was done for disease control and neuropathy symptoms of 344 consecutive patients who received their first BTZ-containing regimen for myeloma or AL amyloidosis before or after we changed to SC weekly in December 2010. Univariate and multivariable analyses were carried out that adjusted for age, underlying disease, concurrently used anticancer agents, underlying conditions predisposing to neuropathy, and number of prior regimens compared SC weekly to other schedules.Fifty-three patients received BTZ SC weekly, 17 SC twice weekly, 127 IV weekly and 147 IV twice weekly. Risk for neuropathy of any grade was higher with other schedules compared to SC weekly (44.3% vs. 26.9%, p = 0.001 while response rate was similar (72.1% vs. 76.6%, respectively, p = 0.15. Multivariable analyses upheld higher neuropathy risk (Odds ratio 2.45, 95% CI 1.26-4.76, p = 0.008 while the likelihood of not achieving a response (= partial response or better was comparable (Odds ratio 1.25, 95% CI 0.58-2.71, p = 0.56 for other schedules compared to SC weekly, respectively. Lower neuropathy risk translated into longer treatment duration when BTZ was started SC weekly (p = 0.001.Weekly SC BTZ has activity comparable to other schedules and causes low rates of neuropathy.

    To evaluate the perinatal results of infants born between 23 and 25.6 weeks of gestation. Medical charts of all women giving birth prematurely (23-25.6 w) from January 2005 to December 2011 were retrospectively reviewed. Cases of malformed infants or deliveries elsewhere were excluded. 198 infants were included. Chorioamnionitis occurred in 86 (43.4%) of the whole group: 26 (86.7%) in the 23-week; 35 (53.8%) in the 24-week and 25 (24.3%) in the 25-week groups. Foetal maturation with antenatal corticosteroids was complete in 119 cases (60.1%): 4 (13.3%) in the 23-week; 35 (53.8%) in the 24-week and 80 (77.7%) in the 25-week groups. Foetal death at birth occurred in 22 cases (11%) and 61 newborns (30.8%) died in the neonatal period. Of the 106 survivors with 2 years complete follow-up, 45 infants (42.4%) did not present sequelae; 16 infants (15.1%) had severe sequelae. A 66.6% (4) of infants born at 23 weeks of gestation did not present sequelae compared with a 32.3% (11) at 24 weeks and 45.4% (30) at 25 weeks. The chorioamnionitis rate was higher when gestational age was lower. The foetal maturation rate was higher when gestational age was higher. A low severe sequelae rate was observed in the whole series, particularly in the 23-week group where the rate was lower than expected; however, these results could have been influenced by the small size of the 23-week group.

    To elucidate the factors that contribute to prolonged pregnancy and promote neonate survival in women with bulging fetal membranes. A database was reviewed to identify women with singleton pregnancies who underwent amniocentesis on admission to determine amniotic fluid neutrophil elastase levels before 26 + 0 weeks gestation between July 2001 and January 2015. Following delivery, the placentas of these patients were examined for histologic chorioamnionitis. Ninety-seven women delivered before 28 weeks gestation, and 117 women delivered at or after 28 weeks gestation. Rescue cerclage performed via the McDonald procedure (adjusted odds ratio [aOR]: 3.78; 95% confidence interval [CI]: 1.35-11.80) was associated with a higher likelihood of reaching at least 28 weeks gestation before delivery, whereas protruding membranes (aOR: 0.38; 95% CI: 0.18-0.78), elevated amniotic neutrophil elastase levels (≥0.15 μg/ml) (aOR, 0.41; 95% CI: 0.20-0.82) and elevated peripheral C-reactive protein levels (≥0.4 mg/dl) (aOR: 0.34; 95% CI: 0.180.65) were associated with a significantly reduced likelihood of reaching this gestational age before delivery. Among women who underwent rescue cerclage, amniorrhexis was associated with a negative prognosis (aOR: 0.18; 95% CI: 0.05-0.51). Intra-amniotic inflammation, protrusion of fetal membranes and amniorrhexis are factors that may prevent pregnancy prolongation. Rescue cerclage improves pregnancy outcomes.

    Full Text Available Bronchogenic cysts are congenital foregut malformations forming from abnormal budding of the bronchial tree between the 4th and 6th weeks of embryonic development. While identified primarily in children, the cysts are often asymptomatic and may not be identified until adulthood. Most (70% are within the middle mediastinum and contain fluid or proteinaceous material. When involving the parenchyma, they generally do not communicate with the tracheobronchial tree. Communication with the airways may develop following infection, procedures, or trauma and may result in lesions with an air-fluid level (Figures 1 and 2. Bronchogenic cysts may be complicated by infection, bleeding, fistula formation, or most concerning, by malignant transformation. Unless the cyst contains air, it may manifest as a solitary pulmonary nodule on plain radiographs. Computed tomography or T2-weighted MRI images are used to confirm the diagnosis.

    To evaluate pregnancy outcome in patients with increased uterine artery (UtA) pulsatility at 34 weeks' gestation as an isolated finding. Normotensive women attending at 34 weeks' gestation for fetal growth assessment were enrolled in the study if fetal growth was appropriate for age and mean UtA pulsatility index (PI) was persistently above the 95(th) centile for gestational age. Patients were excluded with any of the following conditions: multiple pregnancy, sonographic suspicion of fetal anomaly or fetal growth restriction, history of chronic maternal disease, hypertensive disorder or diabetes in the current pregnancy or one or more adverse events in their past obstetric history. The control group consisted of age- and body mass index-matched low-risk women attending at 34 weeks with normal uterine artery Doppler since the midtrimester. Sixty-six normotensive patients with normal fetal growth and increased UtA-PI at 34 weeks were included in the study group. Women with abnormal Doppler findings compared with controls showed significantly lower gestational age at delivery (38.2 ± 1.6 vs. 38.9 ± 1.3 weeks, P = 0.006), birth weight (2942 ± 583 vs. 3404 ± 469 g, P UtA-PI as an isolated finding at 34 weeks' gestation is associated with an increased risk of delivering an SGA neonate.

    2017-04-21

    Sleep Awareness Week, the National Sleep Foundation's annual campaign to educate the public about the importance of sleep in health and safety, will be observed April 23-29, 2017. The amount of sleep a person needs changes with age. Adults need ≥7 hours each night to promote optimal health and well-being (1); children and adolescents require even more sleep. Sleep needs decrease from 12-16 hours of sleep per 24 hours (including naps) for infants aged 4-12 months to 8-10 hours of sleep for teenagers aged 13-18 years (2). Children who regularly sleep less than the recommended amount are more likely to have behavior and learning problems, physical and mental health conditions such as obesity, diabetes, depression, or injuries (2). A regular bedtime routine can help children get adequate sleep. The American Academy of Pediatrics provides advice for parents at https://www.healthychildren.org/English/healthy-living/sleep/. Additional details about how much sleep is recommended across a lifespan is available at https://www.cdc.gov/sleep/about_sleep/how_much_sleep.html.

    2008-01-01

    Prolonged immobilization reduces passive range of motion of joints creating joint contractures. Whether and to what extent these iatrogenic contractures can be reduced is unknown. We raised three questions using an animal model: What degree of contracture remains at the end of a defined remobilization period? Do contractures in sham-operated and immobilized joints differ? What is the contribution of the posterior knee capsule in limiting knee extension? We immobilized one knee of 11 adult male rats in flexion to induce a joint contracture; 10 control animals underwent a sham operation. After 8 weeks, the internal fixation device was removed, and the animals were allowed to resume unrestricted activity for 4 weeks at the end of which the knee range of motion was measured with standardized torques. The mean flexion contracture was higher in the immobilized group (51.9° ± 2.8°) than in the sham-operated group (18.9° ± 2.1°). Eighty-eight percent of the contractures remained in the immobilized group after dividing skin and muscle, suggesting an important contribution of the posterior knee capsule in limiting knee mobility. Based on our preliminary study the range of motion of rat knees immobilized for 8 weeks remained substantially reduced after a 4-week period of unassisted remobilization. PMID:18299947

    To report the outcomes of 38 monoamniotic twin pregnancies managed homogeneously to assess whether continuing the pregnancy past 32 weeks of gestation and vaginal delivery are reasonable options. Single-centre retrospective study including all monoamniotic pregnancies managed over a 20-year period at Port-Royal Obstetrics Department, Paris, France. In the study department, both continuation of the pregnancy up to 36 weeks of gestation and vaginal delivery are allowed for monoamniotic pregnancies in some conditions. Perinatal outcomes are described and then compared according to mode of delivery for patients who gave birth at or after 32 weeks of gestation. Three of the 38 pregnancies included fetal malformations; in two of these cases, both fetuses died in utero at 26 weeks of gestation. In cases without malformations, one twin died in utero in two women at 28.0 and 29.2 weeks of gestation, and both fetuses died in two other women at 24.0 and 24.5 weeks of gestation. Mean gestational age at delivery was 32.9 weeks (range 24.0-36.3). Five women gave birth between 22 and 26 weeks of gestation, six women gave birth between 27 and 31 weeks of gestation, and 27 women gave birth at or after 32 weeks of gestation (26 after excluding those with fetal malformations). No intrauterine or neonatal deaths were observed at or after 32 weeks of gestation. The 28 infants delivered vaginally did not differ significantly from the 22 infants born by caesarean section in terms of umbilical artery pH or 5-min Apgar scores. Continuation of monoamniotic pregnancies beyond 32 weeks of gestation and trial of vaginal delivery are both reasonable options if the parents agree, and optimal surveillance is provided.

    Trichomonas gallinae is a worldwide parasite that causes oropharyngeal avian trichomonosis. During eight years, 60 axenic isolates were obtained from different bird species and characterized by three molecular methods: RAPD analysis and PCR-sequencing of ITS1/5.8S rRNA/ITS2 fragment and Fe-hydrogenase gene. We have found two genotypes of ITS1/5.8S rRNA/ITS2 widely distributed among bird populations, a new variant and also two sequences with mixed pattern. Genotype ITS-OBT-Tg-1 was associated with the presence of gross lesions in birds. We have found eight genotypes of the Fe-hydrogenase (A1, A2, C2, C2.1, C4, C5, C6 and C7), three of them are new reports (C5, C6 and C7), and also three sequences with mixed pattern. Subtype A1 of the Fe-hydrogenase was also related with the presence of lesions. RAPD analyses included most of the strains isolated from animals with lesions in one of the sub-clusters. Potentially pathogenic isolates of T. gallinae obtained in this study fulfill the following criteria with one exception: isolated from lesions+ITS-OBT-Tg-1 genotype+FeHyd A1+RAPD sub-cluster I2.

    It is well known that semi-solid forming could only obtain coarse-grained microstructure in a few alloy systems with a low melting point, such as aluminum and magnesium alloys. This work presents that semi-solid forming could also produce novel bimodal microstructure composed of nanostructured matrix and micro-sized (CoFe)Ti2 twins in a titanium alloy, Ti62Nb12.2Fe13.6Co6.4Al5.8. The semi-solid sintering induced by eutectic transformation to form a bimodal microstructure in Ti62Nb12.2Fe13.6Co6.4Al5.8 alloy is a fundamentally different approach from other known methods. The fabricated alloy exhibits high yield strength of 1790 MPa and plastic strain of 15.5%. The novel idea provides a new insight into obtaining nano-grain or bimodal microstructure in alloy systems with high melting point by semi-solid forming and into fabricating high-performance metallic alloys in structural applications.

Small for gestational age infants had a 12.19 times greater chance of being malnourished at term. Being born at a Type I unit reduced the risk of malnutrition at term by 2.17 times, male sex reduced this risk by 0.4 times and achieving total enteral nutrition by the 10th day of life reduced it by 1.97 times (p < 0.03. CONCLUSIONS: The most effective means of preventing babies being born malnourished is by encouraging perinatal practices aimed at preventing restricted intrauterine growth, in addition to giving priority to aggressive nutritional management.

    Reducing the dietary glycaemic response has been proposed as a way to reduce the risk of diabetes complications. The aim of the present study was to evaluate the glycaemic control and cardiovascular risk biomarkers in fragile, elderly type 2 diabetes patients after the intake of a new fructose-free diabetes-specific formula enriched with resistant-starch type IV and high in monounsaturated fatty acids. Forty-one type 2 diabetes patients aged 78.9 ± 2.8 years were fed exclusively with an enteral diabetes-specific formula for 6 weeks. Data were collected at baseline and after 6 weeks of feeding. Carbohydrate and lipid metabolism and inflammatory and cardiovascular risk biomarkers were measured to evaluated the course of diabetes complications. Blood glycated haemoglobin significantly decreased after the intervention (6.1 ± 0.1 vs. 5.8 ± 0.1 %; pcardiovascular risk without altering lipid metabolism, which is useful for the prevention of diabetic complications. Longer intervention studies are needed in order to validate these results in a larger population.

    Once-weekly teriparatide (human parathyroid hormone [1-34]) (56.5 μg for 72 weeks) injections provided a vertebral fracture risk reduction in Japanese osteoporotic patients evaluated in the Teriparatide Once-Weekly Efficacy Research (TOWER) trial. Using data from the TOWER trial, a subgroup analysis was performed to study the efficacy of once-weekly teriparatide for a variety of baseline clinical risk factors in placebo (n = 281) and teriparatide (n = 261) groups. Significant fracture risk reductions were observed in the subgroups of individuals aged teriparatide group, no incident fracture was observed in the subgroups with a prevalent vertebral fracture number of 0, with grade 0-2 vertebral deformity, or with lumbar BMD ≥2.5 SD. Significant risk reduction was observed in all of the bone turnover marker and estimated glomerular filtration rate subgroups. In conclusion, once-weekly 56.5 μg teriparatide injection reduced the vertebral fracture risk in patients with varying degrees of fracture risk, age, vertebral fracture number and grade, bone turnover level, and renal function.

    Background: There is an inverse relation between the uterine cervical length during pregnancy and the frequency of preterm delivery. The purpose of this study was to construct a chart and evaluate the cervical length at 8 to 38 weeks of normal gestation in the center of Iran. Materials and Methods: Uterine cervical length was measured on 930 asymptomatic pregnant women by abdominal ultrasonographic technique. For statistical evaluation, regression analysis and calculation of percentiles were performed. Results: Our data show a significant decrease in uterine cervical length with increasing gestational age. The mean uterine cervical length exhibits minimal changes from 10 to 24 weeks for most women in this study, although the shortening is more prominent at 33 to 38 weeks’ gestation. The mean shortening of the uterine cervical length between the second and the ninth months was 14.82% (P < 0.05). Also, the cervical length means in trimesters 1, 2 and 3 were 39.30 ± 4.33, 38.28 ± 5.13 and 36.58 ± 4.58 mm, respectively. The third trimester showed a significant reduction (P < 0.05) in cervical length compared to the first and second trimesters (6.92% and 4.44%, respectively). New charts with the 5th, 10th, 50th, 90th, and 95th percentile are presented. Conclusion: Our study provides a new chart and reference values for normal uterine cervical length throughout gestation based on a large sample in the center of Iran. There was a progressive decrease in mean uterine cervical length with increasing gestational age in the population of this study. Our established charts for uterine cervical length throughout gestation might be more useful than a single cut-off value for more efficient prevention and management of preterm birth. PMID:26261817

    Full Text Available A longitudinal and prospective study was carried out at two state-operated maternity hospitals in Belo Horizonte during 1996 in order to assess the weight of preterm appropriate-for-gestational-age newborns during the first twelve weeks of life. Two hundred and sixty appropriate-for-gestational-age preterm infants with birth weight <2500 g were evaluated weekly. The infants were divided into groups based on birth weight at 250-g intervals. Using weight means, somatic growth curves were constructed and adjusted to Count's model. Absolute (g/day and relative (g kg-1 day-1 velocity curves were obtained from a derivative of this model. The growth curve was characterized by weight loss during the 1st week (4-6 days ranging from 5.9 to 13.3% (the greater the percentage, the lower the birth weight, recovery of birth weight within 17 and 21 days, and increasingly higher rates of weight gain after the 3rd week. These rates were proportional to birth weight when expressed as g/day (the lowest and the highest birth weight neonates gained 15.9 and 30.1 g/day, respectively. However, if expressed as g kg-1 day-1, the rates were inversely proportional to birth weight (during the 3rd week, the lowest and the highest weight newborns gained 18.0 and 11.5 g kg-1 day-1, respectively. During the 12th week the rates were similar for all groups (7.5 to 10.2 g kg-1 day-1. The relative velocity accurately reflects weight gain of preterm infants who are appropriate for gestational age and, in the present study, it was inversely proportional to birth weight, with a peak during the 3rd week of life, and a homogeneous behavior during the 12th week for all weight groups.

    Objectives The aims of this study were to (i) investigate the association between night work or long work weeks and the risk of accidental injuries and (ii) test if the association is affected by age, sex or socioeconomic status. Methods The study population was drawn from the Danish version of the European Labour Force Survey from 1999-2013. The current study was based on 150 438 participants (53% men and 47% women). Data on accidental injuries were obtained at individual level from national health registers. We included all 20-59-year-old employees working ≥32 hours a week at the time of the interview. We used Poisson regression to estimate the relative rates (RR) of accidental injuries as a function of night work or long work weeks (>40 hours per week) adjusted for year of interview, sex, age, socioeconomic status (SES), industry, and weekly working hours or night work. Age, sex and SES were included as two-way interactions. Results We observed 23 495 cases of accidental injuries based on 273 700 person years at risk. Exposure to night work was statistically significantly associated with accidental injuries (RR 1.11, 99% CI 1.06-1.17) compared to participants with no recent night work. No associations were found between long work weeks (>40 hours) and accidental injuries. Conclusion We found a modest increased risk of accidental injuries when reporting night work. No associations between long work weeks and risk of accidental injuries were observed. Age, sex and SES showed no trends when included as two-way interactions.

    The compressional and shear wave velocities for coesite have been measured simultaneously up to 5.8 GPa and 1073 K by ultrasonic interferometry for the first time. The shear wave velocity decreases with pressure along all isotherms. The resulting contrasts between coesite and stishovite reach ~34% and ~45% for P and S wave velocities, respectively, and ~64% and ~75% for their impedance at mantle conditions. The large velocity and impedance contrasts across coesite-stishovite transition imply that to generate the velocity and impedance contrasts observed at the X-discontinuity, only a small amount of silica would be required. The velocity jump dependences on silica, d(lnVP)/d(SiO2) = 0.38 (wt %)-1 and d(lnVS)/d(SiO2) = 0.52 (wt %)-1, are utilized to place constraints on the amount of silica in the upper mantle and provide a geophysical approach to track mantle eclogite materials and ancient subducted oceanic slabs.

    FT-IR and FT-Raman spectra of 1-hydroxy-4,5,8-tris(4-methoxyphenyl)anthraquinone were recorded and analyzed. The vibrational wavenumbers were computed using DFT quantum chemical calculations. The data obtained from wavenumber calculations were used to assign the vibrational bands obtained experimentally. A detailed molecular picture of the title compound and its interactions were obtained from NBO analysis. From the MEP plot it is clear that the negative electrostatic potential regions are mainly localized over carbonyl group. There is some evidence of a region of negative electrostatic potential due to π-electron density of the benzo groups. Molecular docking study shows that methoxy groups attached to the phenyl rings and hydroxyl group are crucial for binding and the title compound might exhibit inhibitory activity against PI3K and may act as an anti-neoplastic agent.

    Adequate production of progesterone by the corpus luteum is critical to the successful establishment of pregnancy. In animal models, bone morphogenetic protein (BMP) 4 and BMP7 have been shown to suppress either basal or gonadotropin-induced progesterone production, depending on the species examined. However, the effects of BMP4 and BMP7 on progesterone production in human granulosa cells are unknown. In the present study, we used immortalized (SVOG) and primary human granulosa-lutein cells to investigate the effects of BMP4 and BMP7 on steroidogenic acute regulatory protein (StAR) expression and progesterone production and to examine the underlying molecular mechanism. Treatment of primary and immortalized human granulosa cells with recombinant BMP4 or BMP7 decreased StAR expression and progesterone accumulation. In SVOG cells, the suppressive effects of BMP4 and BMP7 on StAR expression were blocked by pretreatment with inhibitors of activin receptor-like kinase (ALK)2/3/6 (dorsomorphin) or ALK2/3 (DMH1) but not ALK4/5/7 (SB-431542). Moreover, small interfering RNA-mediated depletion of ALK3, but not ALK2 or ALK6, reversed the effects of BMP4 and BMP7 on StAR expression. Likewise, BMP4- and BMP7-induced phosphorylation of SMAD 1/5/8 was reversed by treatment with DMH1 or small interfering RNA targeting ALK3. Knockdown of SMAD4, the essential common SMAD for BMP/TGF-β signaling, abolished the effects of BMP4 and BMP7 on StAR expression. Our results suggest that BMP4 and BMP7 down-regulate StAR and progesterone production via ALK3 and SMAD1/5/8-SMAD4 signaling in human granulosa-lutein cells.

    The gut is the most extensively studied niche of the human microbiome. The aim of this study was to characterise the initial gut microbiota development of a cohort of breastfed infants (n = 192) from 1 to 24 weeks of age. V4-V5 region 16S rRNA amplicon Illumina sequencing and, in parallel, bacteriological culture. The metabolomic profile of infant urine at 4 weeks of age was also examined by LC-MS. Full-term (FT), spontaneous vaginally delivered (SVD) infants' microbiota remained stable at both phylum and genus levels during the 24-week period examined. FT Caesarean section (CS) infants displayed an increased faecal abundance of Firmicutes (p microbiota closely resembling FT-SVD (which remained stable) by week 8 of life, which was maintained at week 24. The gut microbiota of preterm (PT) infants displayed a significantly greater abundance of Proteobacteria compared to FT infants (p microbiota of the infants. Tryptophan and tyrosine metabolic pathways, as well as fatty acid and bile acid metabolism, were found to be affected by delivery mode and gestational age. These findings confirm that mode of delivery and gestational age both have significant effects on early neonatal microbiota composition. There is also a significant difference between the metabolite profile of FT and PT infants. Prolonged breastfeeding was shown to have a significant effect on the microbiota composition of FT-CS infants at 24 weeks of age, but interestingly not on that of FT-SVD infants. Twins had more similar microbiota to one another than between two random infants, reflecting the influence of similarities in both host genetics and the environment on the microbiota..

    Muscular power is important for maintaining physical functioning with aging. Proper quantification of the reliability of muscular power tests is crucial to inform monitoring of individuals and sample size planning for interventional studies. This study evaluated short- and long-term reliability of leg extensor power measurement in 72 adults (age 62.7 ± 8.6 years). Participants completed four repeat trials on the Nottingham leg extensor power rig, with a further trial twelve weeks later. Mean change, typical error, and intraclass correlation coefficients (ICC) were calculated. For short-term reliability, mean change in power output was trivial after two trials (1.2-4.8%). Typical errors were small following four trials in the dominant leg of males (10.9-5.8%), three in the non-dominant leg of males (9.9-6.2%) and the dominant leg of females (10.0-9.6%) and two in the non-dominant leg in females (8.3%). Intraclass correlation coefficients (ICCs) were very high (0.88-0.96). For long-term reliability, mean change remained trivial (1.0-2.5%), typical errors remained small (5.8-8.6%), and ICCs very high (0.94-0.96). The leg extensor power rig is a reliable method for assessing lower body muscular power, both short- and long-term, with only minimal habituation effects.

    Middle-aged women with active commuting had significantly lower risk for wrist fracture than women commuting by car/bus. Our purpose was to investigate whether a physically active lifestyle in middle-aged women was associated with a reduced risk of later sustaining a low-trauma wrist fracture. The Umeå Fracture and Osteoporosis (UFO) study is a population-based nested case-control study investigating associations between lifestyle and fragility fractures. From a cohort of ~35,000 subjects, we identified 376 female wrist fracture cases who had reported data regarding their commuting habits, occupational, and leisure physical activity, before they sustained their fracture. Each fracture case was compared with at least one control drawn from the same cohort and matched for age and week of reporting data, yielding a total of 778 subjects. Mean age at baseline was 54.3 ± 5.8 years, and mean age at fracture was 60.3 ± 5.8 years. Conditional logistic regression analysis with adjustments for height, body mass index, smoking, and menopausal status showed that subjects with active commuting (especially walking) were at significantly lower risk of sustaining a wrist fracture (OR 0.48; 95 % CI 0.27-0.88) compared with those who commuted by car or bus. Leisure time activities such as dancing and snow shoveling were also associated with a lower fracture risk, whereas occupational activity, training, and leisure walking or cycling were unrelated to fracture risk. This study suggests that active commuting is associated with a lower wrist fracture risk, in middle-aged women.

    The optimal timing of separating the mink dam from the litter is suggested to be a balance between the partly conflicting needs of the mother and the kits. Early removal of the dam or partial removal of the litter may protect the dam against exhaustion. Little is known about the maternal motivation...... (8w, N=189) after birth. The aim was to investigate whether the dams had a different motivation to take care of the litter after 7 and 8 weeks, estimated by non-invasive determination of cortisol (FCM: Faecal Corticsol Metabolites) and dam calls the first week after separation. The two treatment.......014). Likewise, the dam calls increased on the separation day, peaking on the first day after separation (D1). The proportion of dams with calls decreased with litter age at separation (P=0.024). We interpret these results as a higher maternal motivation in dams at 7 weeks than at 8 weeks after delivery...

    To compare bone mineral density (BMD) in patients with or without weekly injection of teriparatide to promote bone ingrowth after cementless total knee arthroplasty (TKA). Records of 8 men and 32 women (mean age, 75.6 years) who underwent cementless TKA for medial knee osteoarthritis with (n=20) or without (n=20) once-weekly subcutaneous/hypodermic injection of teriparatide for 48 weeks were reviewed. BMD and bone volume/total volume (BV/TV) of the bone-prosthesis interface of the proximal tibia in 6 regions of interest (ROI) were assessed at 3, 6, 9, and 12 months using multi-detector computed tomography. Patients with or without weekly injection of teriparatide after cementless TKA were comparable in terms of baseline characteristics and pre- and post-operative knee range of motion and Knee Society knee and function scores. In ROI 1 (medial), ROI 3 (anteromedial), and ROI 4 (posteromedial), the BV/TV increased throughout the postoperative period in patients with weekly injection of teriparatide and declined after 6 months in patients without weekly injection of teriparatide. These 3 ROIs of the 2 groups differed significantly only in BMD at 6, 9, and 12 months. In ROI 2 (lateral), ROI 5 (anterolateral), and ROI 6 (posterolateral), both BV/TV and BMD showed a decreasing trend, and these 3 ROIs of the 2 groups did not differ significantly. Weekly injection of teriparatide after cementless TKA promoted bone ingrowth mostly in the medial aspect of the bone-prosthesis interface.

    Purpose: To evaluate the efficacy and toxicity of weekly paclitaxel with concurrent radiotherapy followed by adjuvant chemotherapy (AC) in patients with locally advanced nasopharyngeal carcinoma (NPC). Methods and materials: Between 2004 and 2007, 54 patients with locally advanced NPC were included in this protocol. Patient characteristics: median age 48; 69% male; 52% World Health Organization (WHO) III; 50% stage III, 50% stage IV. The patients underwent a course of definitive conventional radiotherapy (70 Gy in 7 weeks with 2 Gy/fraction), with concurrent weekly paclitaxel 35 mg/m 2 from the first to the sixth week of radiation. AC was started 4 weeks after the end of the radiotherapy (RT), paclitaxel 135 mg/m 2 on day 1 and cisplatin 30 mg/m 2 on days 1-3 were administered every 4 weeks for two cycles. Results: Median follow-up was 32 months. Eighty-five percentage of complete response and 15% partial response were achieved at the time of one month after AC. The 3-year actuarial rate of local regional control was 86%; distant metastases-free survival, progression-free survival and overall survival at 3 years were 81%, 69% and 76%, respectively. Forty-nine (91%) patients completed six courses of concurrent chemotherapy with weekly paclitaxel, and 4 (7%) patients delayed at the second cycle of AC. No patient developed severe acute toxicities. Conclusions: Weekly paclitaxel with concurrent RT followed by AC is a potentially effective and toxicity tolerable method for locally advanced NPC. Further studies are needed to identify the optimal dose of weekly paclitaxel in this strategy.

    To evaluate neonatal survival after prolonged preterm premature rupture of membranes (PROM) in the era of antenatal corticosteroids, surfactant, and inhaled nitric oxide. A single-center retrospective cohort study of neonates born from 2002-2011 after prolonged (1 week or more) preterm (less than 24 weeks of gestation) rupture of membranes was performed. The primary outcome was survival to discharge. Neonates whose membranes ruptured less than 24 hours before delivery (n=116) were matched (2:1) on gestational age at birth, sex, and antenatal corticosteroid exposure with neonates whose membranes ruptured 1 week or more before delivery (n=58). Analysis used conditional logistic regression for categorical data and Wilcoxon signed rank test for continuous data. The prolonged preterm PROM exposed and unexposed cohorts had survival rates of 90% and 95%, respectively, although underpowered to assess the statistical significance (P=.313). Exposed neonates were more likely have pulmonary hypoplasia (26/58 exposed, 1/114 unexposed, Prupture (20.4 weeks exposed, 22.3 weeks unexposed, P=.189), length of rupture (3.7 weeks exposed, 6.4 weeks unexposed, P=.717), and lowest maximal vertical pocket before 24 weeks of gestation (0 cm exposed, 1.4 cm unexposed, P=.114) did not discriminate between survivors and nonsurvivors after exposure to prolonged preterm PROM. With antenatal steroid exposure and aggressive pulmonary management, survival to discharge after prolonged preterm PROM was 90%. Pulmonary morbidities were common. Of note, the data were limited to women who remained pregnant 1 week or longer after rupture of membranes.

    Respiratory muscle endurance training (normocapnic hyperpnoea, RMET) improves maximal volitional ventilation (MVV) and respiratory muscle endurance while volitionally-assessed respiratory muscle strength remains unchanged (prior-to-post comparison). What remains unclear is how respiratory muscle function changes/adapts during a defined period of RMET in highly-trained subjects. This study assessed respiratory muscle function during a six-week period of RMET in 13 highly-trained, healthy subjects. Weekly-assessed twitch mouth pressure (prior/post 2.20 ± 0.41 kPa vs. 2.43 ± 0.61 kPa; p=0.14); twitch transdiaphragmatic pressure (prior/post 3.04 ± 0.58 kPa vs. 3.13 ± 0.48 kPa; p=0.58) and maximal inspiratory pressure (prior/post 12.6 ± 3.6 kPa vs. 13.9 ± 3.8 kPa; p=0.06) did not increase. MVV (prior/post 175 ± 18 l/min vs. 207 ± 30 l/min; p=0.001), sniff nasal pressure (prior/post 11.8 ± 2.8 kPa vs. 14.0 ± 2.9 kPa; p=0.003) and maximal expiratory pressure (prior/post 16.9 ± 5.8 kPa vs. 20.9 ± 4.9 kPa; p=0.006) each increased. In conclusion, non-volitionally assessed diaphragmatic strength does not increase during six weeks of RMET in highly-trained subjects, while expiratory muscle strength and MVV rose. Future studies should clarify if these findings apply when assessed during respiratory muscle strength rather than endurance training. Copyright © 2013 Elsevier B.V. All rights reserved.

  7. Topical Retinol Restores Type I Collagen Production in Photoaged Forearm Skin within Four Weeks

    Directory of Open Access Journals (Sweden)

    Full Text Available Production of type I collagen (COL1, the major structural protein of the skin, declines during aging, leading to skin thinning and becoming fragile, which increases the risk of bruising and wound healing disorders in the elderly. Topical treatments that can restore COL1 synthesis and ultimately COL1 content in aged skin hold promise to improve skin health. Much effort has been spent on developing agents that can safely and effectively enhance COL1 synthesis in aged skin. However, how fast and to what extent COL1 production in aged skin can be enhanced by a topical treatment remains unclear. Herein, we investigated a four-week topical retinol (ROL treatment. A one-day occlusion of ROL (0.4% or vehicle was applied on photoaged forearms of elderly (>65 years old subjects once a week for four weeks. Vehicle was also applied on forearms of young (23–33 years subjects in the same manner. Skin samples were obtained one week after the last treatment and analyzed for COL1 synthesis. We found that the ROL treatment increased the level of COL1 mRNA (2.3-fold and proCOL1 protein (1.8-fold in photoaged forearms to levels similar to that of young forearms within four weeks. Our study proves the concept that reduced COL1 production in aged skin can be readily restored. In addition, our study provides an evidence-based foundation for developing COL1-enhancing topical agents, and establishes a reliable and practical efficacy test for evaluating such agents.

    This report describes the synthesis of analogs of 4-[1-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydro-2-naphthyl)ethynyl]benzoic acid (1), commonly known as bexarotene, and their analysis in acting as retinoid-X-receptor (RXR)-specific agonists. Compound 1 has FDA approval to treat cutaneous T-cell lymphoma (CTCL); however, its use can cause side effects such as hypothyroidism and increased triglyceride concentrations, presumably by disruption of RXR heterodimerization with other nuclear receptors. The novel analogs in the present study have been evaluated for RXR activation in an RXR mammalian-2-hybrid assay as well as an RXRE-mediated transcriptional assay, and for their ability to induce apoptosis, as well as for their mutagenicity and cytotoxicity. Analysis of 11 novel compounds revealed the discovery of 3 analogs that best induce RXR-mediated transcriptional activity, stimulate apoptosis, have comparable Ki and EC50 values to 1, and are selective RXR agonists. Our experimental approach suggests that rational drug design can develop new rexinoids with improved biological properties. PMID:19791803

    Full Text Available Abstract: Tri-t-butylgallium has been reacted with the macrocycle 1,12-diaza-3,4:9,10-dibenzo-5,8-dioxocyclopentadecane which could be a potential ligand for gallium(III. A reaction product was analyzed and single crystal X-ray diffraction experiments showed that it consisted of the cyclic dimer of di-t-butylgallium-hydroxide hydrogen bonded to the macrocycle. Without a co-crystallized organic molecule di-t-butylgallium hydroxide crystallizes as a trimer. Density functional calculations have been used to predict the structures and the total energies for the monomer, dimer, trimer, and tetramer of dimethylgallium hydroxide in order to provide a basis for the understanding of oligomer population for the dimethylgallium hydroxides. Force field calculations are shown to be able to produce a similar strain energy difference for dimer, trimer, and tetramer forms of (CH32Ga(OH and this method can economically be used for larger alkyl groups. The force field computations show that the trimeric di-t-butyl gallium(III hydroxide is much more stable than the dimeric form which therefore must owe its existence to the association with the hydrogen-bonded macrocycle.

    Full Text Available Abstract Background The 5,8-disubstituted indolizidines are the largest class of poison-frog alkaloids found in anuran skin, and are of considerable interest because of their inhibitory effects on the neuronal nicotinic acetylcholine receptors. Many synthetic strategies for the construction of this nucleus have been reported: however, a flexible route has not been reported to date. Results Synthesis of lactam chiral building blocks for the flexible synthesis of the title alkaloids has been achieved using a Michael-type conjugate addition reaction to a chiral cyclic enamine ester as the key step in constructing the trisubstituted piperidine ring system. To demonstrate the usefulness of these chiral building blocks, syntheses of (--203A, (--205A from 1, and (--219F from 2 have been achieved. Conclusion The total synthesis of (--203A, (--205A, and (--219F was achieved, and the absolute stereochemistry of natural 203A was determined to be 5S, 8R, 9S. In addition, the relative stereochemistry of natural 219F was determined.

    The ZZ production cross section has been measured by the ATLAS experiment using the four-lepton decay channel, where the term lepton implies electrons and muons. A data sample of 5.8 fb$^{−1}$ collected in $pp$ collisions at $\\sqrt s$ = 8 TeV at the LHC in 2012 is used. Events are selected by requiring four leptons with $p_\\mathrm{T}$ > 15 GeV, forming two opposite-sign same-flavour lepton pairs with mass between 66 GeV and 116 GeV, with the leading lepton required to have $p_\\mathrm{T} > 25$ GeV. We observe 85 candidate events in the acceptance region $|\\eta| < 2.5$ for muons ($|\\eta| < 2.47$ for electrons) with a background expectation of 1.3$\\pm$1.2(stat.)$\\pm$0.5(syst.). The $ZZ\\to\\ell^+\\ell^-\\ell^{\\prime+}\\ell^{\\prime-}$ production cross section, measured in a fiducial phase-space corresponding closely to the acceptance defined above, is 21.0$^{+2.4}_{−2.2}$(stat.)$^{+0.6}_{−0.5}$(syst.)$\\pm$0.8(lumi.) fb.

    In the treatment of dental caries, less invasive methods are strongly required. However, conventional dental lasers cannot always achieve selective removal of caries or good bonding with a composite resin. Based on the optical absorption characteristics of dentin, wavelengths around 6 μm are promising in this regard. Our previous study indicated the possibility of selective removal of demineralized dentin using a nanosecond pulsed laser at wavelengths around 6 μm. In the present study, the optimal laser irradiation conditions were investigated for achieving selective removal of demineralized dentin. Bovine dentin was used, and its laser ablation characteristics were evaluated. The results indicated that demineralized dentin could be selectively removed, without causing cracking or damage to sound dentin, at laser wavelengths of 5.75 and 5.80 μm and average power densities of 30-40 W/cm(2). These optimal laser irradiation conditions also realized higher bonding strength with a composite resin than was possible using an Er:YAG laser. The use of nanosecond pulses allowed the thermal confinement condition to be satisfied, leading to a reduction in tissue damage, including degradation of dental pulp vitality. Thus, a nanosecond pulsed laser at 5.8 μm was found to be effective for less invasive caries treatment.

    Large scale electronic phase separation (EPS) between ferromagnetic metallic and charge-ordered insulating phases in La{sub 5/8-y}Pr{sub y}Ca{sub 3/8}MnO{sub 3} (y = 0.3) (LPCMO) is very sensitive to the structural changes. This work investigates the effects of post-annealing on the strain states and electrical transport properties of LPCMO films epitaxially grown on (001){sub pc} SrTiO{sub 3} (tensile strain), LaAlO{sub 3} (compressive strain) and NdGaO{sub 3} (near-zero strain) substrates. Before annealing, all the films are coherent-epitaxial and insulating through the measured temperature range. Obvious change of film lattice is observed during the post-annealing: the in-plane strain in LPCMO/LAO varies from −1.5% to −0.1% while that in LPCMO/STO changes from 1.6% to 1.3%, and the lattice of LPCMO/NGO keeps constant because of the good lattice-match between LPCMO and NGO. Consequently, the varied film strain leads to the emergence of metal-insulator transitions (MIT) and shift of the critical transition temperature in the electrical transport. These results demonstrate that lattice-mismatch combined with post-annealing is an effective approach to tune strain in epitaxial LPCMO films, and thus to control the EPS and MIT in the films.

    Walker, S, Serrano, J, and Van Roie, E. Maximum dynamic lower-limb strength was maintained during 24-week reduced training frequency in previously sedentary older women. J Strength Cond Res 32(4): 1063-1071, 2018-There is little study into the effects of reducing strength training below the recommended twice weekly frequency, particularly in older women, despite the possibility that individuals will encounter periods of reduced training frequency. The purpose of the present study was to determine the effects of a period of reduced training frequency on maximum strength and muscle mass of the lower limbs in comparison with the recommended training frequency of twice per week. After an initial 12-week period, where all subjects trained twice per week, a reduced strength training group (RST) trained once per week, whereas another strength training group (ST) continued to train twice per week for 24 weeks. A nontraining age-matched control group (CON) was used for comparison. All subjects were tested for leg press 1-repetition maximum (1RM), electromyogram (EMG) amplitude of vastus lateralis and medialis, and quadriceps cross-sectional area (CSA) measured by panoramic ultrasound at weeks 0, 12, and 36. Both ST and RST continued to increase 1RM during the reduced training frequency period compared with control (∼8% and ∼5% vs. ∼-3%, respectively; p ≤ 0.05). Accompanying these changes were significant increases in EMG amplitude in both ST and RST (p ≤ 0.05). However, the initial gains in quadriceps CSA made from week 0 to week 12 in RST were lost when training once per week (RST ∼-5%). Therefore, reduced training frequency in this population does not adversely affect maximum strength or muscle activity but can negatively affect muscle mass, even reversing training-induced gains. Older individuals not training at least twice per week may compromise potential increases in muscle mass, important in counteracting effects of aging.

  19. Weekly Cycle of Lightning: Evidence of Storm Invigoration by Pollution

    We have examined summertime 1998 2009 U.S. lightning data from the National Lightning Detection Network (NLDN) to look for weekly cycles in lightning activity. As was found by Bell et al. (2008) for rain over the southeast U.S., there is a significant weekly cycle in afternoon lightning activity that peaks in the middle of the week there. The weekly cycle appears to be reduced over population centers. Lightning activity peaks on weekends over waters near the SE U.S. The statistical significance of weekly cycles over the western half of the country is generally small. We found no evidence of a weekly cycle of synoptic-scale forcing that might explain these patterns. The lightning behavior is entirely consistent with the explanation suggested by Bell et al. (2008) for the cycles in rainfall and other atmospheric data from the SE U.S., that aerosols can cause storms to intensify in humid, convectively unstable environments.

    Physical activity has been shown to maintain or improve autonomy in the elderly. It has also been demonstrated that vibration exercise in adults achieves rapid benefits. This study analyses the effects of an 8-week program of reduced volume vibration training on autonomy and strength in a group of elderly subjects. The 23 participants (18 women and 5 men, aged between 70 and 92 years, mean age 81.2 years) underwent a training program of five 30-second series of mechanical vibrations at 25 Hz and 2 mm wavelength three times a week for eight weeks. The isometric strength of the extensor muscles of the knee was assessed with a MuscleLab(®) gauge, and autonomy was tested with the "Expanded-Timed-Get-Up-and-Go" (ETGUG) test, both before and immediately after the eight weeks of the program and then eight weeks afterwards. Significant differences were detected between the three time points in strength, and also in total time taken to complete the ETGUG and the various sections of the test, with the exception of the time taken to stand up and to turn. The vibration training program significantly improved the time taken to complete the ETGUG and strength after eight weeks of training. However, these benefits only endured for walking speed, not for strength. The results of the ETGUG test revealed significant changes overall. However, in two sections (standing up and turning) the differences were not significant, probably because the results do not depend exclusively on participants' physical capacity but are also related to their coordination skills. Eight weeks of reduced volume vibration training in the elderly improved autonomy, but not isometric strength. Copyright © 2012 SEGG. Published by Elsevier Espana. All rights reserved.

    Once-weekly 56.5-μg teriparatide treatment was significantly associated with the increase in lumbar spine bone mineral density at 48 weeks among hemodialysis patients with hypoparathyroidism and low bone mass; however, discontinuation of treatment because of adverse events was frequently observed. Careful monitoring for adverse events should be required. Once-weekly 56.5-μg teriparatide is reportedly effective for treating osteoporotic patients without renal insufficiency. However, little is known about the efficacy and safety of once-weekly teriparatide in hemodialysis patients. We conducted a 48-week prospective, observational cohort study including 22 hemodialysis patients aged 20 years or older with hypoparathyroidism and low bone mass who received once-weekly teriparatide at 56.5 μg at a tertiary care hospital between January 2013 and January 2015. Primary outcomes were within-subject percent changes of bone mineral density (BMD) at the lumbar spine, femoral neck, and distal one-third radius at 24 and 48 weeks. Secondary outcomes included percent changes of serum bone turnover markers (osteocalcin, bone-specific alkaline phosphatase (BAP), N-terminal propeptide of procollagen type 1 (P1NP), and tartrate-resistant acid phosphatase 5b (TRAP-5b)). Adverse events were evaluated. The BMD increased at the lumbar spine by 3.3 ± 1.9 % (mean ± SEM) and 3.0 ± 1.8 % at 24 and 48 weeks but not in the femoral neck and distal one-third radius. Serum osteocalcin, BAP, and P1NP increased significantly at 4 weeks, maintaining higher concentrations up to 48 weeks, although TRAP-5b decreased gradually during treatment. The baseline BAP was significantly associated with the 48-week percent change in lumbar spine BMD. Transient hypotension was the most common adverse event. Ten patients discontinued treatment because of adverse events. Once-weekly teriparatide was associated with increased lumbar spine BMD in hemodialysis patients with hypoparathyroidism and low

    To evaluate the optimal time for delivery in singleton pregnancies with preterm premature rupture of membranes (PPROM) when delivered between 32 and 36 6/7 weeks gestational age (GA). We performed a retrospective cohort study of all singleton pregnancies with PPROM who delivered between 32 and 36 6/7 weeks gestation at our institution. We matched the delivery and NICU datasets to determine composite morbidity (COMP MORB) and NICU length of stay (LOS) stratified by weeks of gestation. COMP MORB was defined as one or more of: bronchopulmonary dysplasia, respiratory distress syndrome, necrotizing entercolitis, intraventricular hemorrhage, dissiminated intravascular coagulation, and culture proven sepsis. We used χ² and student 't' test as appropriate and a receiver operating characteristc curve (ROC). There were 195 newborns with PPROM with a range of 30 babies at 36 weeks to a high of 53 at 34 weeks. The mean (± SD) NICU LOS was 22.5 (± 9.9) days at 32 weeks, 17.8 (± 10.0) days at 33 weeks, 14.8 (± 11.0) days at 34 weeks, 4.5 (± 4.7) days at 35 weeks, and 1.5 (± 4.4) days at 36 weeks (p < 0.0001). There was no difference in duration of ROM by GA with a range of 6.8 to 1.9 by week (p = NS). The ROC curve had a cut point for COMP MORB at 34.1 weeks GA (sens = 95%, FPR 48.6%, area under curve 0.782, p = 0.0002). Our study suggests that delivery of PPROM pregnancies at 34.1 weeks GA avoids 95% of composite morbidity, and delivery after 35 weeks GA will decrease the NICU LOS.

    Full Text Available The objective of this work was to study the effect of the fatness level on carcass and commercial cuts yields of 5/8 Hereford 3/8 Nellore cull cows, as well as to perform the economic analysis of the marketing of these cuts by the slaughterhouse industry. We used 42 adult cows, all with eight teeth at slaughter, and average live body weight of 530 kg. The experimental design was completely randomized. After slaughter, the carcasses were classified in relation to fat cover, and separated into fat 1 (absent, fat 2 (scarce, fat 3 (median and fat 4 (uniform, according to the “Sistema Nacional de Tipificação e Classificação de Carcaças Bovinas”. Body weights at origin were higher for cows of fat class 4 in relation to class 2 and 1, being 571.9, 517.6, and 488.1 kg, respectively, not differing from fat class 3 (536.6 kg. The hot carcass yields increased as a function of the increase of the degree of carcass finishing, with mean values of 44.4, 46.1, 47.9 and 47.8% for fat classes 1, 2, 3 and 4, respectively. The cut of the rib is the cut with the largest increase in weight when the fat level increases. Considering the commercial cuts prices at the wholesale markets of São Paulo and Rio Grande do Sul, the industry could pay better prices for cows with fat 2 in relation to the other classes. The break-even point of the slaughterhouse industry would be R$ 6.21/kg of carcass for fat 2 cows, against R$ 6.02/kg, R$ 5.99/kg and R$ 5.98/kg, respectively, for fat 1, 3 and 4 cows.

    patients' own assessment of recovery after ambulatory surgery has not been well studied. The aim was to study patients' self-assessed recovery, the occurrence and time course of post-operative problems in relation to the type of ambulatory surgery. a questionnaire was filled in by 355 patients at five time points: pre-operative, first day at home, 1, 2 and 4 weeks post-operatively. Consecutive patients who underwent either inguinal hernia repair (IHR), arthroscopic procedures (AS) or cosmetic breast augmentation (CBA) were included. unplanned return to hospital was rare (3/355). Health care contacts were noted for 9% of the patients during the first week; a total of 70 contacts occurred during the entire period. Pain was the most frequently reported symptom; 40% of the patients reported pain or mobility problems at 1 week, 28% after 2 weeks and 20% after 4 weeks. Pre-operative pain was associated with an increased level of pain during the early post-operative course, in the recovery room and at 1 week post-operatively. IHR was associated with an overall rapid recovery, while AS patients experienced a slower restitution. All AS patients who reported pain after 4 weeks had reported pain problems already pre-operatively. Pain was not present pre-operatively in the CBA group, but was common at 1 and 2 post-operative weeks and was still reported by 11% at 4 weeks. self-assessed recovery was found to cover several weeks with procedure-specific recovery patterns. Pain and mobility impairment were still frequently reported 4 weeks post-operatively. 2010 The Acta Anaesthesiologica Scandinavica Foundation.

    PURPOSE This trial was designed to evaluate the optimal dose of massage for individuals with chronic neck pain. METHODS We recruited 228 individuals with chronic nonspecific neck pain from an integrated health care system and the general population, and randomized them to 5 groups receiving various doses of massage (a 4-week course consisting of 30-minute visits 2 or 3 times weekly or 60-minute visits 1, 2, or 3 times weekly) or to a single control group (a 4-week period on a wait list). We assessed neck-related dysfunction with the Neck Disability Index (range, 0–50 points) and pain intensity with a numerical rating scale (range, 0–10 points) at baseline and 5 weeks. We used log-linear regression to assess the likelihood of clinically meaningful improvement in neck-related dysfunction (≥5 points on Neck Disability Index) or pain intensity (≥30% improvement) by treatment group. RESULTS After adjustment for baseline age, outcome measures, and imbalanced covariates, 30-minute treatments were not significantly better than the wait list control condition in terms of achieving a clinically meaningful improvement in neck dysfunction or pain, regardless of the frequency of treatments. In contrast, 60-minute treatments 2 and 3 times weekly significantly increased the likelihood of such improvement compared with the control condition in terms of both neck dysfunction (relative risk = 3.41 and 4.98, P = .04 and .005, respectively) and pain intensity (relative risk = 2.30 and 2.73; P = .007 and .001, respectively). CONCLUSIONS After 4 weeks of treatment, we found multiple 60-minute massages per week more effective than fewer or shorter sessions for individuals with chronic neck pain. Clinicians recommending massage and researchers studying this therapy should ensure that patients receive a likely effective dose of treatment. PMID:24615306

    This study compared the effects of different weekly training frequencies on the cardiovascular and neuromuscular adaptations induced by concurrent training in previously trained elderly. After 20weeks of combined strength and endurance training, twenty-four healthy elderly men (65±4 years) were randomly placed into two frequency training groups: strength and endurance training performed twice a week (SE2, n=12); or, strength and endurance training performed three times per week (SE3, n=12). The interventions lasted 10 weeks and each group performed identical exercise intensity and volume per session. Before and after the exercise training, one maximum repetition test (1RM), isometric peak torque (PT), maximal surface electromyographic activity (EMG), as well as muscle thickness (MT) were examined. Additionally, peak oxygen uptake (VO(2peak)), maximum aerobic workload (W(max)), first and second ventilatory thresholds (VT1 and VT2) were evaluated. There were significant increases in upper and lower-body 1RM, MT, VO(2peak), VT1 and VT2, with no differences between groups. There were no changes after training in maximal EMG and isometric peak torque. W(max) was improved only in SE3. After 10 weeks of training, twice weekly combined strength and endurance training leads to similar neuromuscular and cardiovascular adaptations as three times per week, demonstrating the efficiency of lower frequency of concurrent training in previously trained elderly men. © 2013.

    Vaccination has been shown to reduce mortality and morbidity due to vaccine-preventable diseases. However, these diseases are still responsible for majority of childhood deaths worldwide especially in the developing countries. This may be due to low vaccine coverage or delay in receipt of age-appropriate vaccines. We studied the timeliness of routine vaccinations among children aged 12-59 months attending infant welfare clinics in semi-urban areas of The Gambia, a country with high vaccine coverage. A cross-sectional survey was conducted in four health centres in the Western Region of the Gambia. Vaccination dates were obtained from health cards and timeliness assessed based on the recommended age ranges for BCG (birth-8 weeks), Diphtheria-Pertussis-Tetanus (6 weeks-4 months; 10 weeks-5 months; 14 weeks-6 months) and measles vaccines (38 weeks-12 months). Risk factors for delay in age-appropriate vaccinations were determined using logistic regression. Analysis was limited to BCG, third dose of Diphtheria-Pertussis -Tetanus (DPT3) and measles vaccines. Vaccination records of 1154 children were studied. Overall, 63.3% (95 % CI 60.6-66.1%) of the children had a delay in the recommended time to receiving at least one of the studied vaccines. The proportion of children with delayed vaccinations increased from BCG [5.8% (95 % CI 4.5-7.0%)] to DPT3 [60.4% (95 % CI 57.9%-63.0%)] but was comparatively low for the measles vaccine [10.8% (95 % CI 9.1%-12.5%)]. Mothers of affected children gave reasons for the delay, and their profile correlated with type of occupation, place of birth and mode of transportation to the health facilities. Despite high vaccination coverage reported in The Gambia, a significant proportion of the children's vaccines were delayed for reasons related to health services as well as profile of mothers. These findings are likely to obtain in several countries and should be addressed by programme managers in order to improve and optimize the impact of the

    First-trimester screening for fetal aneuploidy using nuchal translucency (NT), pregnancy-associated plasma protein A, free or total beta-hCG, and maternal age constitutes a very effective screening test for fetal Down syndrome. We describe a case in which a patient presented at 14 weeks' gestation with an acute abdomen 1 week after first-trimester screening (including NT measurement) performed elsewhere, which was negative for trisomies 21 and 18. Sonographic examination revealed an interstitial pregnancy with a singleton fetus with present cardiac activity, which had not been noted 1 week earlier at the time of earlier transabdominal NT measurement. This case indicates that successful acquisition of a NT measurement during first-trimester screening for fetal aneuploidy does not negate the rare possibility of an unusual ectopic pregnancy. 2008 Wiley Periodicals, Inc.

    Hypertensive disorders are associated with maternal and neonatal complications. Though they are more common in women with history of prior preeclampsia, they can occur in uncomplicated pregnancies. To determine the proportion of adverse pregnancy outcomes in deliveries prior to or at ≥39 weeks, in uncomplicated singleton nulliparous women (low-risk), as well as women with history of preeclampsia in a prior gestation (high-risk). This was a secondary analysis from the multicenter trials of low dose aspirin for preeclampsia prevention in low and high-risk pregnancies. The proportion of adverse pregnancy outcomes including hypertensive disorders in pregnancy, small for gestational age, placental abruption, neonatal intensive critical unit admission, and respiratory distress syndrome were evaluated in the two groups. Adverse pregnancy outcomes were stratified by gestational age at delivery (39 weeks and ≥39 weeks). Descriptive statistics were performed, and results reported as percentages. Three thousand twenty-one pregnancies were included in the low risk group, and 600 in the high risk one. In the low risk group 362 (12%) had hypertensive disorders, with 58% occurring at ≥39 weeks. In the low risk group, the rate of small for gestational age was of 5.9%, placental abruption 0.4%, neonatal intensive care unit admission 9%, and respiratory distress syndrome 3.5%. Sixty percent of all small for gestational age, 31% of all placenta abruptions, 44% of all neonatal intensive care unit admissions and 33% of respiratory distress syndrome cases, occurred at ≥39 weeks in the low risk group. In contrast in the high risk group, 197 (33%) patients developed a hypertensive disorder, with 35.5% occurring at ≥39 weeks. The overall rate of small for gestational age was 9.2%, abruption 2%, neonatal intensive care unit admission 15.5%, and respiratory distress syndrome 5%. In this group, 24% of all small for gestational age, 8.3% of all placental abruptions, 16% of all

  16. An Iterative Travel Time Inversion and Waveform Modeling Method to Determine the Crust Structure and Focal Mechanism: Case Study of 2015 Alxa Left Banner Ms5.8 Earthquake

    Science.gov (United States)

    Song, C.; Ge, Z.

    2017-12-01

    The boundary region between Alxa Block and Ordos Block is an area of stress concentration with strong seismicity and frequent small earthquakes. However, the knowledge of this area is limited since only a few seismic stations were deployed in this area. The 2015 Ms5.8 Alxa Left Banner Earthquake on April 15 is the largest one occurred in the surroundings since the 1976 Ms6.2 Bayinmuren Earthquake. Abundant stations built in the northern part of Chinese North-South Seismic Belt recorded this event sequence well within short distance, which provides us a great opportunity to carry out studies. We use these data to obtain a mean 1-D layered velocity structure via iterative inversion based on both travel time and waveform misfits. Then we use the travel time difference between data and synthetic seismograms to relocate the epicenter. Finally we invert the best double-couple focal mechanism and centroid depths of the source. As the result, the source is located at (39.7027° N, 106.4207° E) with a depth of 18 km and Mw 5.28. Nodal plane Ⅰ has strike 86°, dip angle 90° and slip angle -3°, while plane Ⅱ has strike 176°, dip angle 87° and slip angle 180°. Considering the dynamic structure of regional fault zone, we believe this earthquake is caused by a nearly pure left-lateral strike-slip fault with nodal plane Ⅰ being the fault plane. The seismogenic structure is likely to be an E-W striking buried fault nearby. There develops several groups of NE, NEE and E-W striking faults in Jilantai tectonic zone, parts of which have been verified by geophysical investigations. But we still know little about the dynamic nature of them. From our study, the corresponding fault of this event may indicate all groups of faults with same E-W strike has the common character of large-dip left-lateral strike-slip. Moreover, there may be some buried faults being newly born or not found yet. These results could be an important supplement to the future research of seismicity and

    We analyzed the development of the area of the penis and erectile structures (corpora cavernosa and corpus spongiosum) and the thickness of the tunica albuginea during the fetal period (13 to 36 weeks after conception) in humans to establish normative patterns of growth. We studied 56 male human fetuses at 13 to 36 weeks after conception. We used histochemical and morphometric techniques to analyze the parameters of total penile area, area of corpora cavernosa, area of corpus spongiosum, and thickness of tunica albuginea in the dorsal and ventral regions using ImageJ software (National Institutes of Health, Bethesda, Maryland). Between 13 and 36 weeks after conception the area of the penis varies from 0.95 to 24.25 mm2. The area of the corpora cavernosa varies from 0.28 to 9.12 mm2, and the area of the corpus spongiosum varies from 0.14 to 3.99 mm2. The thickness of the tunica albuginea varies from 0.029 to 0.296 mm in the dorsal region and from 0.014 to 0.113 mm in the ventral region of the corpora cavernosa. We found a strong correlation between the total penile area, corpora cavernosa and corpus spongiosum with fetal age (weeks following conception). The growth rate was more intense during the second trimester (13 to 24 weeks of gestation) compared to the third trimester (25 to 36 weeks). Tunica albuginea thickness also was strongly correlated with fetal age and this structure was thicker in the dorsal vs ventral region.

    To describe the perinatal and infant and early childhood morbidity associated with preterm premature rupture of membranes (PROM) in a cohort of twin pregnancies evaluated prospectively with neonatal follow-up to 2 years of age. This was a secondary analysis of a randomized controlled trial of magnesium sulfate for prevention of cerebral palsy. Inclusion criteria were twin gestation with preterm PROM diagnosed between 24 0/7 and 31 6/7 weeks of gestation and planned expectant management. Latency (time from membrane rupture to delivery) and perinatal outcomes were evaluated by gestational age at membrane rupture. Long-term neonatal outcomes were also analyzed. Among 151 women who met inclusion criteria, the median gestational age at preterm PROM was 28.1 weeks (range 24.1-31.6 weeks). Approximately one-third of women achieved a latency of at least 1 week. Gestational age at preterm PROM (odds ratio [OR] 0.75, 95% confidence interval [CI] 0.63-0.90 for each week after 24 weeks of gestation) and cervical dilation at admission (OR 0.66, 95% CI 0.49-0.90 for each centimeter of dilation) were inversely associated with a latency period of at least 1 week. There were no stillbirths (95% CI 0-1%), but the rate of neonatal mortality was 90 per 1,000 newborns (95% CI 57-112) with a 7.3% cerebral palsy rate among survivors (95% CI 4.4-10.3%). In twin pregnancies, preterm PROM from 24 to 31 weeks of gestation is associated with a neonatal mortality rate of 9.0% and an overall cerebral palsy rate of 7.3%. A longer latency period is associated with less advanced cervical dilation and later gestational age at PROM. LEVEL OF EVIEDENCE: II.

  20. Weekly patterns of aerosol in the United States

    Directory of Open Access Journals (Sweden)

    D. M. Murphy

    2008-05-01

    Full Text Available Data from the Interagency Monitoring of Protected Visual Environments (IMPROVE network of aerosol samplers and NOAA monitoring sites are examined for weekly cycles. At remote and rural sites, fine particle elemental carbon, crustal elements, and coarse particle mass had pronounced (up to 20% weekly cycles with minima on Sunday or Monday. Fine particle organic carbon and mass had smaller amplitude cycles, also with Sunday or Monday minima. There was no statistically significant weekly cycle in fine particle sulfate despite a 5 to 15% weekly cycle in power plant SO2 emissions. Although results for nitrate may be more susceptible to sampling artifacts, nitrate also showed a pronounced weekly cycle with an amplitude similar to elemental carbon. The only species found with a weekend maximum was Pb, probably from general aviation on weekends. Aerosol optical properties at NOAA monitoring sites were consistent with the IMPROVE chemical data, with significant weekly cycles in aerosol light absorption but not light scattering. These results support a large role of diesel emissions in elemental carbon aerosol over the entire United States and suggest that a large fraction of the airborne soil dust is anthropogenic. They also suggest that studies of weekly cycles in temperature, cloudiness, precipitation, or other meteorological variables should look for causes more in light-absorbing particles and possible ice nucleation by dust rather than sulfate or total aerosol. There are also implications for personal exposure and epidemiological studies of aerosol health effects.

    Full Text Available Objectives: This study aimed to evaluate the changing survival rate and morbidities among infants born before 26 gestational weeks at the Sultan Qaboos University Hospital (SQUH in Muscat, Oman. Methods: This retrospective study assessed the mortality and morbidities of all premature infants born alive at 23–26 gestational weeks at SQUH between June 2006 and May 2013. Infants referred to SQUH within 72 hours of birth during this period were also included. Electronic records were reviewed for gestational age, gender, birth weight, maternal age, mode and place of delivery, antenatal steroid administration, morbidity and outcome. The survival rate was calculated and findings were then compared with those of a previous study conducted in the same hospital from 1991 to 1998. Rates of major morbidities were also calculated. Results: A total of 81 infants between 23–26 gestational weeks were admitted to the neonatal unit during the study period. Of these, 58.0% were male and 42.0% were female. Median gestational age was 25 weeks and mean birth weight was 770 ± 150 g. Of the 81 infants, 49 survived. The overall survival rate was 60.5% compared to 41% reported in the previous study. Respiratory distress syndrome (100.0%, retinopathy of prematurity (51.9%, bronchopulmonary dysplasia (34.6%, intraventricular haemorrhage (30.9% and patent ductus arteriosus (28.4% were the most common morbidities. Conclusion: The overall survival rate of infants between 23–26 gestational weeks during the study period had significantly improved in comparison to that found at the same hospital from 1991 to 1998. There is a need for the long-term neurodevelopmental follow-up of premature infants.

    To evaluate whether a department policy changing the scheduling of the postpartum visit from 6 weeks to 2-3 weeks after delivery is associated with higher long-acting reversible contraception initiation at the postpartum visit. We conducted a quasiexperimental before-after study to evaluate long-acting reversible contraception initiation, specifically an intrauterine device or contraceptive implant, at the postpartum visit between women scheduled for follow-up at 6 weeks (before policy change) and 2-3 weeks after delivery (after policy change). Secondary outcomes included postpartum visit completion, overall contraception initiation at the postpartum visit, overall contraceptive use at 6 months after delivery, and repeat pregnancies by 6 months postpartum. We obtained delivery and postpartum information using the electronic medical record and contacted participants 3 and 6 months after delivery to assess contraception use and repeat pregnancies. We enrolled 586 participants between December 2014 and November 2015, of whom 512 women (256 in each cohort) continued to meet eligibility criteria after delivery. Long-acting reversible contraception initiation rates at the postpartum visit were lower in the 2- to 3-week (16.5%, 95% CI 12.2-21.8) compared with the 6-week group (31.1%, 95% CI 25.2-37.7, Pcontraception initiation was higher in the 2- to 3-week group (27.3%, 95% CI 21.9-33.4) compared with the 6-week group (15.8%, 95% CI 11.5-21.4, Pcontraceptive use patterns at 6 months postpartum. No intrauterine device perforations or expulsions were observed in women who underwent insertion at 2-3 weeks postpartum. Five pregnancies were reported in each cohort by 6 months after delivery. Scheduling a visit at 2-3 weeks after delivery was not associated with increased long-acting reversible contraception initiation at this visit despite higher postpartum visit attendance.

    Prenatal magnetic resonance (MR) imaging is currently used to measure quantitative data concerning brain structural development. At present, morphometric MR imaging studies have been focused mostly on the third trimester of gestational age. However, in many countries, because of legal restriction on abortion timing, the majority of MR imaging fetal examination has to be carried out during the last part of the second trimester of pregnancy (i.e., before the 24th week of gestation). Accurate and reliable normative data of the brain between 20 and 24 weeks of gestation is not available. This report provides easy and practical parametric support to assess those normative data. From a database of 1,200 fetal MR imaging studies, we retrospectively selected 84 studies of the brain of fetuses aged 20-24 weeks of gestation that resulted normal on clinical and radiological follow-up. Fetuses with proved or suspected infections, twin pregnancy, and fetuses of mothers affected by pathology that might have influenced fetal growth were excluded. Linear biometrical measurements of the main cerebral structures were obtained by three experienced pediatric neuroradiologists. A substantial interobserver agreement for each measurements was reached, and normative data with median, maximum, and minimum value were obtained for brain structures. The knowledge of a range of normality and interindividual variability of linear biometrical values for the developing brain between 20th and 24th weeks of gestation may be valuable in assessing normal brain development in clinical settings.

    Full Text Available Objective: This exploratory study sought to measure current self-reported experiences of older Saudi adults. Method: Self-reported aging perceptions and demographic data from semistructured questions were obtained from 52 community-dwelling older Saudi adults aged 50 or older. A thematic content analysis was completed around issues of family life/social support, daily/weekly activities, health and health programs, and older adults’ own thoughts about aging and the experience and future of personal aging. Results: Several key themes emerged from the interviews. The majority of respondents in this preliminary study acknowledge a preference for family care. Formal programs in Saudi Arabia are attended with relative infrequency while older adults recognize family support as the preferred method of support. Older Saudi interviewees hold a positive view of aging, but physical functioning, varying financial resources, and other daily obligations are a concern for those in this study. Discussion: Data suggest as the Saudi population ages, more research is needed on the aging experience with particiular emphasis on issues relevant to older adults . Future research must work to clarify the aging experience as cultural context changes.

    This retrospective study of all women who accessed the 2006 Manitoba Pap Test Week clinics was designed to determine factors associated with inadequate cervical cancer screening and changes in cervical cancer screening behavior. Data were acquired using the CervixCheck Manitoba registry and an ancillary database of demographic information collected from clinic attendees. The study included 1124 women. Of these, 53% (n = 598) were under-screened (no Pap test in the previous 2 years) prior to accessing the clinics. Logistic regression analyses demonstrated that older age (odds ratio [OR] = 1.02, 95% confidence interval [CI] 1.01-1.03), no doctor (OR = 1.4, 95% CI 1.05-1.54), and living in Canada Pap Test Week clinics. Thirty-seven percent (n = 223) of under-screened women demonstrated improved screening status subsequent to the 2006 Pap Test Week (had a subsequent Papanicolaou [Pap] test performed within 2 years) and these women were more likely to live in an urban setting (P = 0.003), be younger (P Pap test result in 2006 (P Pap test performed at a Pap Test Week clinic compared to having a Pap test performed elsewhere (37% versus 60%, P Pap Test Week clinics whose screening status might be most modifiable.

The sample was 31 elderly women, with x _ = 68.97 years (SD = 5.34, all participants in a water exercise program. The women were tested in November 2005 and, after a 12-week pause in water exercises, in March2006, using the American Alliance for Health, Physical Education, Recreation and Dance – AAHPERD test battery. The statistical analysis was descriptive, using simple frequencies and percentages, plus the t test for paired samples. A statistically significant difference was observed between mean scores for coordination, agility and the general functional fitness index (GFFI at the end of the exercise program and 12 weeks later. The GFFI and coordination scores had reduced after the 12-week period, but the participants’ agility had improved. It was concluded that a 12-week pause in water exercise impacted the GFFI of these elderly women. These results emphasize the importance of physical exercise during the ageing process and of raising awareness of the need for the elderly to keep physically active even during the holiday period in order to improve and/or maintain functional fitness levels.

    To investigate the association between weekly lottery sales and number of suicide deaths in Taiwan. All suicides aged 15+ years during 2004-2006 in Taiwan were included. Poisson autoregression time series models investigated associations of weekly numbers with contemporaneous and recent sales from two national lotteries in operation. Adjustments were made for seasonal fluctuation, temperature, monthly unemployment and autocorrelation. In fully adjusted models, suicide deaths were negatively correlated with sales of tickets for a low-prize, low-cost lottery system. However, they were correlated positively with recent sales for a higher-cost, larger-prize system. Both correlations were stronger for male than female suicide numbers but differed in terms of age groups most strongly implicated. Associations between lottery sales and suicide numbers differed according to the nature of the lottery. A low-prize, low-publicity system appeared to be more benign than a high-prize, high-publicity one.

  20. A comparison of practice pattern and outcome of twice-weekly and thrice-weekly hemodialysis patients

    Full Text Available Renal replacement therapy (RRT options and practice varies in countries worldwide and is influenced by patients' choice, nephrologists' practice patterns, health system, payer practice, public policy, and socioeconomic factors. In India, hemodialysis (HD remains the dominant RRT modality, and the practice is largely influenced by socioeconomics of the region of practice since third party payer is limited. Resource stretch to maximize outcome benefit is essential and HD session twice weekly is an improvized and cost-effective clinical practice. However, within the country, the patient characteristics, practice patterns, and outcomes of twice-weekly HD compared against patients dialyzed thrice weekly remain unclear. We did a retrospective analysis of patients who underwent twice- and thrice-weekly HD in a single center under similar settings. The patients on thrice a week dialysis were older and with a higher proportion of diabetics and were insured by private payers. Weight gain, ultrafiltration rates, blood pressures, and hemoglobin remained more favorable in the thrice-weekly patients. There was no significant difference in the hospitalization rates or mortality rates in the two groups. Patients who undergo twice-weekly HD have poorer intermediate measures of the outcome; although, morbidity and survival were not different in a small study population with short follow-up. The small sample size and the short duration of follow-up may limit the scope of findings of our study.

    The 2006 Kidney Disease Outcomes Quality Initiative guidelines suggest twice-weekly or incremental hemodialysis for patients with substantial residual kidney function (RKF). However, in most affluent nations de novo and abrupt transition to thrice-weekly hemodialysis is routinely prescribed for all dialysis-naïve patients regardless of their RKF. We review historical developments in hemodialysis therapy initiation and revisit twice-weekly hemodialysis as an individualized, incremental treatment especially upon first transitioning to hemodialysis therapy. In the 1960's, hemodialysis treatment was first offered as a life-sustaining treatment in the form of long sessions (≥10 hours) administered every 5 to 7 days. Twice- and then thrice-weekly treatment regimens were subsequently developed to prevent uremic symptoms on a long-term basis. The thrice-weekly regimen has since become the 'standard of care' despite a lack of comparative studies. Some clinical studies have shown benefits of high hemodialysis dose by more frequent or longer treatment times mainly among patients with limited or no RKF. Conversely, in selected patients with higher levels of RKF and particularly higher urine volume, incremental or twice-weekly hemodialysis may preserve RKF and vascular access longer without compromising clinical outcomes. Proposed criteria for twice-weekly hemodialysis include urine output >500 ml/day, limited interdialytic weight gain, smaller body size relative to RKF, and favorable nutritional status, quality of life, and comorbidity profile. Incremental hemodialysis including twice-weekly regimens may be safe and cost-effective treatment regimens that provide better quality of life for incident dialysis patients who have substantial RKF. These proposed criteria may guide incremental hemodialysis frequency and warrant future randomized controlled trials. © 2015 S. Karger AG, Basel.

  2. Concomitant weekly cisplatin and radiotherapy for head and neck cancer

    The most common chemoradiotherapy regimen is high-dose (100 mg/m 2 ) three-weekly cisplatin with concomitant radiotherapy; however, this protocol is associated with acute and late toxicities. Here, we reviewed the dose intensity and toxicity for concomitant weekly cisplatin and radiotherapy in patients with head and neck cancer. Fifty-three patients with untreated head and neck cancer were enrolled and evaluated at our institution from April 2006 to April 2010. Weekly cisplatin (40 mg/m 2 ) was given on weeks 1, 2, 3, 5, 6 and 7 with radiotherapy, which comprised a standard dose of 70 Gy delivered in 35 daily fractions over 7 weeks. Fifty-one patients (96.2%) received the full dose of radiotherapy, while the course was disrupted by adverse events in two. Over the course of the chemotherapy, 31 patients (58.5%) received more than 200 mg/m 2 cisplatin. The toxicity was manageable in all except one patient, who died of sepsis after completing treatment. The 2-year overall survival rate and local progression-free rate for all patients were 93.7% and 88.0%, respectively. The primary site showed a complete response in 52 patients (98.1%) and a partial response in 1 patient (1.9%). The primary disease was well controlled by chemoradiotherapy in 47 patients (88.7%). Weekly cisplatin could be easier to manage than three-weekly cisplatin, because patients can be monitored more regularly for toxicity allowing the schedule to be altered if required. This regimen appears to be a suitable alternative to three-weekly high-dose cisplatin with concomitant radiotherapy. (author)

    Optimal management of pregnancies at 39 weeks gestational age is unknown. Therefore, we sought to perform a comparative effectiveness analysis of elective induction of labor (eIOL) at 39 weeks among nulliparous women with non-anomalous singleton, vertex fetuses as compared to expectant management (EM) which included IOL for medical or obstetric indications or at 41 weeks in undelivered mothers. A Monte Carlo micro-simulation model was constructed modeling two mutually exclusive health states: eIOL at 39 weeks, or EM with IOL for standard medical or obstetrical indications or at 41 weeks if undelivered. Health state distribution probabilities included maternal and perinatal outcomes and were informed by a review of the literature and data derived from the Consortium of Safe Labor. Analyses investigating preferences for maternal versus infant health were performed using weighted utilities. Primary outcome was determining which management strategy posed less maternal and neonatal risk. Secondary outcomes were rates of cesarean deliveries, maternal morbidity and mortality, stillbirth, neonatal morbidity and mortality, and preferences regarding the importance of maternal and perinatal health. A management strategy of eIOL at 39 weeks resulted in less maternal and neonatal risk as compared to EM with IOL at 41 weeks among undelivered patients. Cesarean section rates were higher in the EM arm (35.9% versus 13.9%, p39 week eIOL still resulted in fewer cesarean deliveries as compared to EM (8.0% versus 26.1%, p39 week eIOL was favored over EM. Mathematical modeling revealed that eIOL at 39 weeks resulted in lower population risks as compared to EM with induction of labor at 41 weeks. Specifically, eIOL at 39 weeks resulted in a lower cesarean section rate, lower rates of maternal morbidity, fewer stillbirths and neonatal deaths, and lower rates of neonatal morbidity.

    Week Hospital is an innovative inpatient health care organization and management, by which hospital stay services are planned in advance and delivered on week-time basis to elective patients. In this context, a strategic decision is the optimal clinical management of patients, and, in particular, devising efficient and effective admission and scheduling procedures, by tackling different requirements such as beds' availability, diagnostic resources, and treatment capabilities. The main aim is to maximize the patient flow, by ensuring the delivery of all clinical services during the week. In this paper, the optimal management of Week Hospital patients is considered. We have developed and validated an innovative integer programming model, based on clinical resources allocation and beds utilization. In particular, the model aims at scheduling Week Hospital patients' admission/discharge, possibly reducing the length of stay on the basis of an available timetable of clinical services. The performance of the model has been evaluated, in terms of efficiency and robustness, by considering real data coming from a Week Hospital Rheumatology Division. The experimental results have been satisfactory and demonstrate the effectiveness of the proposed approach.

    Full Text Available Little is known about motor development in late preterm born infants. Our objective was to determine long-term outcome of motor skills of infants born between 32 and 34 weeks. All infants were assessed at corrected ages of 3 and 9 months, using the Alberta Infant Motor Scale. At corrected ages of 4 years, the Movement Assessment Battery for Children was done. Seventy infants were seen at 4 years of age (median of 3 assessments per infant. Abnormal assessment at 3 or 9 months of age resulted in normal outcome in almost 80% at 4 years. On the other hand, a normal outcome in the first year of life resulted in an abnormal outcome at 4 years in 10% of the infants. Our results suggest that long-term followup of these late preterm born infants is necessary, as the assessments in the first year do not predict the long-term outcome.

    2001-06-01

    Until now, prospective studies of aging have begun with 50-60-year-olds, not adolescents. Premature death, childhood variables, and alcohol abuse have been often ignored, as has successful aging. The authors reviewed the existing literature on health in late life in order to highlight that, increasingly, successful aging is not an oxymoron. The present study followed two cohorts of adolescent boys (237 college students and 332 core-city youth) for 60 years or until death. Complete physical examinations were obtained every 5 years and psychosocial data every 2 years. Predictor variables assessed before age 50 included six variables reflecting uncontrollable factors: parental social class, family cohesion, major depression, ancestral longevity, childhood temperament, and physical health at age 50 and seven variables reflecting (at least some) personal control: alcohol abuse, smoking, marital stability, exercise, body mass index, coping mechanisms, and education. The six outcome variables chosen to assess successful aging at age 70-80 included four objectively assessed variables (physical health, death and disability before age 80, social supports, and mental health) and two self-rated variables (instrumental activities of daily living and life enjoyment). Multivariate analysis suggested that "good" and "bad" aging from age 70-80 could be predicted by variables assessed before age 50. More hopeful still, if the seven variables under some personal control were controlled, depression was the only uncontrollable predictor variable that affected the quality of subjective and objective aging. One may have greater personal control over one's biopsychosocial health after retirement than previously recognized.

This research has not, however, sufficiently considered that the age range of considered partners might change over the life span. Here we investigated the age limits (youngest and oldest) of considered and actual sex partners in a population-based sample of 2,655 adults (aged 18-50 years). Over the investigated age span, women reported a narrower age range than men and women tended to prefer slightly older men. We also show that men's age range widens as they get older: While they continue to consider sex with young women, men also consider sex with women their own age or older. Contrary to earlier suggestions, men's sexual activity thus reflects also their own age range, although their potential interest in younger women is not likely converted into sexual activity. Compared to homosexual men, bisexual and heterosexual men were more unlikely to convert young preferences into actual behavior, supporting female-choice theory.

    To describe morbidity in neonates born by cesarean section (CS) before labor between 34(+0) and 38(+6) weeks, stratified by gestational age. Cohort study from five Italian tertiary care hospitals. Consecutive singleton pregnancies delivered by CS before labor between 34(+0) and 38(+6) weeks of gestation from January 2010 to August 2011 were included. Women in labor, with premature rupture of membranes, or with previous administration of steroids were excluded. The incidence of neonatal complication by gestational week was calculated. A total of 1135 cases were analyzed. Composite adverse neonatal outcomes, respiratory distress syndrome, transient tachypnea and use of continuous airway positive pressure decreased from 50%, 28%, 5% and 22% at 34 weeks of gestation, to 4.7%, 1.0%, 0.9% and 0.3% at 38 weeks of gestation. Multivariate analysis showed that the only variable independently associated with composite adverse neonatal outcome was gestational age at delivery (adjusted odds ratio 0.49; 95% confidence interval 0.39-0.61). The prevalence of neonatal complications in newborns delivered by CS before labor halves at each week of gestation from 34 to 38 weeks. Nonetheless complications, and mainly respiratory problems, are still present at early term gestation.

    Weekly multimicronutrient supplementation was initiated as an appropriate intervention to protect poor urban populations from anemia. To identify the lessons learned from the Integrated Food Security Program (Programa Integrado de Seguridad Alimentaria [PISA]) weekly multimicronutrient supplementation program implemented in poor urban populations of Chiclayo, Peru. Data were collected from a 12-week program in which multimicronutrient supplements were provided weekly to women and adolescent girls 12 through 44 years of age and children under 5 years of age. A baseline survey was first conducted. Within the weekly multimicronutrient supplementation program, information was collected on supplement distribution, compliance, biological effectiveness, and cost. Supplementation, fortification, and dietary strategies can be integrated synergistically within a micronutrient intervention program. To ensure high cost-effectiveness of a weekly multimicronutrient supplementation program, the following conditions need to be met: the program should be implemented twice a year for 4 months; the program should be simultaneously implemented at the household (micro), community (meso), and national (macro) levels; there should be governmental participation from health and other sectors; and there should be community and private sector participation. Weekly multimicronutrient supplementation programs are cost effective options in urban areas with populations at low risk of energy deficiency and high risk of micronutrient deficiencies.

    1. A total of 11 826 records from 2489 quails, hatched between 2012 and 2013, were used to estimate genetic parameters for BW (body weight) of Japanese quail using random regression models. Weekly BW was measured from hatch until 49 d of age. WOMBAT software (University of New England, Australia) was used for estimating genetic and phenotypic parameters. 2. Nineteen models were evaluated to identify the best orders of Legendre polynomials. A model with Legendre polynomial of order 3 for additive genetic effect, order 3 for permanent environmental effects and order 1 for maternal permanent environmental effects was chosen as the best model. 3. According to the best model, phenotypic and genetic variances were higher at the end of the rearing period. Although direct heritability for BW reduced from 0.18 at hatch to 0.12 at 7 d of age, it gradually increased to 0.42 at 49 d of age. It indicates that BW at older ages is more controlled by genetic components in Japanese quail. 4. Phenotypic and genetic correlations between adjacent periods except hatching weight were more closely correlated than remote periods. The present results suggested that BW at earlier ages, especially at hatch, are different traits compared to BW at older ages. Therefore, BW at earlier ages could not be used as a selection criterion for improving BW at slaughter age.

    in adolescents aged 13-17 with schizophrenia were randomized 2:1 to olanzapine or placebo. ER was defined as ≥20 % reduction in Brief Psychiatric Rating Scale-children (BPRS-C) total score at week 2 (ER2) or 3 (ER3); UR was defined with increasing stringency as total BPRS-C score reduction ≥20, ≥30, ≥40 or ≥50...... %; remission was defined cross-sectionally using Andreasen et al. (2005) criteria. By week 2 (n = 69) and 3 (n = 66), olanzapine-treated youth achieved 73.3 and 85.5 % of their overall BPRS-C score reduction at 6 weeks last observation carried forward. ER and ENR patients did not differ significantly regarding...... and ENR groups. Adolescents with schizophrenia experienced the majority of symptomatic improvement early during olanzapine treatment. ER predicted UR and remission, with ER3 having best predictive power. A ≥ 20 % improvement threshold for defining ER was confirmed as a robust outcome indicator....

    Full Text Available Introduction: The menopause transition is associated with decreased health functioning. About 80-90% of women experience mild to severe physical or physiological menopause-related complaints per year when approaching menopause. Physical activity may reduce some climacteric symptoms and improve the quality of life. Aim of the study was to investigate the influence of a 12-week training programme on the quality of life (QoL in menopausal-aged women living in a rural area. Material and methods: Participants were 80 women aged 40-65 years and divided into two randomly selected groups in training sessions (exercising group, n = 40 and control group, n = 40. SF36 was used to assess the quality of life in both groups before and after 12 weeks. Exercising women participated in training session 3 times a week. Each 60-minute exercise session included warming-up exercises, walking, stretching, strengthening exercises with an elastic band and cooling down exercises. Results : A non-significant positive difference in all SF36 domains in the exercising group was observed. The results of the study showed a statistically significant higher QoL in the exercising group compared to the control group after 12-week training in two domains: vitality and mental health. The improvement in the quality of life in the study group was 0.19 points (role limits – physical domain, least change and 4.96 (vitality domain, most change. Conclusions : Controlled and regular exercise for 12 weeks was significantly correlated with a positive change in vitality and mental health. Sedentary women should consider modification of their lifestyle to include physical activity as it leads to improvement of their quality of life.

    Although dapsone is a commonly used alternative agent for prophylaxis against Pneumocystis carinii pneumonia in children intolerant to trimethoprim-sulfamethoxazole, there are few data that describe dapsone pharmacokinetics in children. We studied dapsone pharmacokinetics in 30 children (median age, 2.8 years; age range, 0.3 to 12 years) receiving a new proprietary liquid preparation by three dosing regimens (1 mg/kg of body weight daily, 2 mg/kg daily, or 4 mg/kg weekly). Dosing of children with 2 mg/kg daily or 4 mg/kg weekly resulted in peak concentrations equivalent to those reached in adults receiving 100-mg tablets daily. For the entire population, the median half-life was 22.2 h (range, 7.1 to 40.3 h), the median oral clearance was 0.0365 liter/kg/h (range, 0.0104 to 0.1021 liter/kg/h), and the median oral apparent volume of distribution was 1.13 liters/kg (range, 0.50 to 2.32 liters/kg). The median dapsone oral clearance was significantly increased in those infants less than 2 years of age compared to the oral clearance in those over 2 years of age (0.0484 versus 0.0278 liter/kg/h; P = 0.011). These data suggest that absorption of this liquid preparation is adequate and that the concentrations in the sera of children receiving 2 mg/kg daily or 4 mg/kg weekly are equivalent to those seen in adults receiving standard dapsone dosing. Dapsone oral clearance appears to be increased in children under 2 years of age. PMID:10543733
