Efectos de un programa de meditación (mindfulness) en la medida de la alexitimia y las habilidades sociales

Effects of a meditation program (mindfulness) on the measure of alexithymia and social skills. This study aimed to determine whether training in meditation (mindfulness) produced effects on measures of alexithymia and social skills in a group of students. The results indicated that the meditation program produced significant differences in the variable social skills and in five of its factors at posttest. In the intra-analysis, the differences were significant both in alexithymia and in social skills, and in all its factors in the experimental group, and no significant differences were observed in the control group. The percentages of change in the experimental group presented reductions in the total score of alexithymia and its three factors of about 20% and an increase in the variable social skills and its six factors ranging between 15.96 and 22.60%. In the control group, the two variables and their factors ranged from -0.14 to 4.43%. These results should be considered with caution as the study sample was non-clinical and relatively small; therefore, these results should be confirmed with larger samples and patients with high alexithymia.
Contractile Response of Spontaneously Hypertensive Rat Caudal Artery to Phorbol Esters

Stimulation of pbosphatidylinositol metabolism by neurotransmitters produces diacylglycerol, an activator of protein kinase C, which may be involved in hormone-mediated contractions. We studied the effect of a tumor-promoting phorbol ester, 12-deoxyphorbol 13-isobutyrate 20-acetate (DPBA), on contraction of caudal artery rings of Wistar-Kyoto control (WKY) and spontaneously hypertensive rats (SHR) in order to examine whether protein kinase C-mediated mechanisms are increased in SHR. Although DPBA alone did not produce contractions of either WKY or SHR caudal artery rings, it greatly potentiated the contractions evoked by norepinephrine, vasopressin, potassium, and calcium ionophore A23187. The potentiation of contractile response to these agents by DPBA was dependent on extracellular calcium. The DPBA potentiation of contractions evoked by norepinephrine, vasopressin, and potassium was significantly greater (p < 0.05) in SHR than in WKY, while no differences were observed between strains for the contractions evoked by calcium ionophore A23187. These results indicate that the protein kinase C-mediated responses are increased in SHR caudal artery rings, and this effect appears to be due to increased calcium influx through cell membrane calcium channels.
Nanotechnology and Nanotoxicology in Retinopathy

Nanoparticles are nanometer-scaled particles, and can be utilized in the form of nanocapsules, nanoconjugates, or nanoparticles themselves for the treatment of retinopathy, including angiogensis-related blindness, retinal degeneration, and uveitis. They are thought to improve the bioavailability in the retina and the permeability of therapeutic molecules across the barriers of the eye, such as the cornea, conjunctiva, and especially, blood-retinal barriers (BRBs). However, consisting of multiple neuronal cells, the retina can be the target of neuronal toxicity of nanoparticles, in common with the central and peripheral nervous system. Furthermore, the ability of nanoparticles to pass through the BRBs might increase the possibility of toxicity, simultaneously promoting distribution in the retinal layers. In this regard, we discussed nanotechnology and nanotoxicology in the treatment of retinopathy.
Trace gas and radical diurnal behavior in the marine boundary layer during INDOEX 1999

Arabia causing, for instance, a reduction in j(O( 1 D)) by up to 40%. The diurnal behavior of the trace gases and parameters in the MBL has been investigated by using a timedependent zero-dimensional chemical model. Significant differences between the diurnal behavior of RO* 2 derived from the model and observed in measurements were identified. The measured HCHO concentrations differed from the model results and are best explained by some missing chemistry involving low amounts of Cl. Other possible processes describing these two effects are presented and discussed.

Les nouvelles formes d’organisation du travail : Le rôle des perspectives contingente et institutionnelle

Cette etude analyse le taux de penetration des nouvelles formes d’organisation du travail (NFOT) ainsi que leurs determinants. Pour ce faire, les perspectives contingente et institutionnelle ont ete mises a profit afin de caracteriser les facteurs explicatifs des NFOT dans 252 entreprises quebecoises. Les resultats de cette etude sont concluants : la perspective contingente explique mieux la presence des NFOT lorsque le taux de penetration de ces pratiques est eleve, alors que la perspective institutionnelle s’avere dominante lorsque ce taux est faible. Concretement, les resultats suggerent que la strategie d’affaires, la gestion participative, le type de culture et la qualite totale, caracterisant la perspective contingente, sont les facteurs determinants d’une penetration elevee des NFOT, alors que le secteur d’activites, la concurrence a l’international et la structure de gouvernance, caracterisant la perspective institutionnelle, expliquent mieux la presence des NFOT lorsque celles-ci sont implantees superficiellement.
The relevance of ligament balancing in total knee arthroplasty: how important is it? A systematic review of the literature

Ligament balancing affects many of the postoperative criteria for a successful knee replacement. A balanced knee contributes to improved alignment and stability. Ligament balancing helps reduce wear and loosening of the joint. A patient with a balanced knee is more likely to have increased range of motion and proprioception, and decreased pain. All these factors help minimize the need for revision surgery. Complications associated with ligament balancing can include instability caused by over-balancing and the possibility of neurovascular damage during or as a result of ligament balancing. This article attempts to summarize the literature, to define a balanced knee, and outline the benefits and possible complications of ligament balancing. Different techniques, sequences, and tools used in ligament balancing, and their relevance in correcting various deformities are reviewed.
Assessing the reliability and validity of the Self-Report Psychopathy Scales in a UK offender population

This study assessed the reliability and validity of the Hare Self-Report Psychopathy Scale (Hare SRP) and the short form of the measure in a UK prison sample, using the Psychopathy Checklist Revised (PCL-R) as a reference measure. The Hare SRP and PCL-R were compared for 107 UK adult male prisoners. The SRP and SRP-SF total scores depicted excellent levels of internal consistency and homogeneity and correlated with each other with significant and large effects sizes. Total scores correlated with PCL-R total scores producing medium effect sizes and were significantly predictive of PCL-R total scores with small effect sizes. Implications for practice are discussed.
Potentiodynamic polarization study of the in vitro corrosion behavior of 3 high-palladium alloys and a gold-palladium alloy in 5 media.

STATEMENT OF PROBLEM Corrosion of cast alloy restorations may lead to their failure or adversely affect their biocompatibility. Although some documentation of the corrosion behavior of the high-palladium dental alloys exists, questions remain about their corrosion resistance and mechanisms. PURPOSE This study compared the in vitro corrosion characteristics of 3 high-palladium alloys and 1 gold-palladium alloy in simulated body fluid and oral environments. MATERIAL AND METHODS Two Pd-Cu-Ga alloys and 1 Pd-Ga alloy were selected; an Au-Pd alloy served as the control. The corrosion behavior for the as-cast and simulated porcelain-firing (heat-treated) conditions of each alloy (N = 5) was evaluated in 0.9% NaCl, 0.09% NaCl, and Fusayama solutions. Heat-treated specimens of each alloy (N = 5) were also tested in N(2)-deaerated 0.09% NaCl and Fusayama solutions (pH 4). After immersion in the electrolyte for 24 hours, the open-circuit potential (OCP) was measured, and linear polarization was performed from -20 mV to +20 mV (vs. OCP) at a scanning rate of 0.125 mV/s. Cyclic polarization was performed from -300 mV to +1000 mV and back to -300 mV (vs. OCP) at a scanning rate of 1 mV/s. Data were evaluated with analysis of variance and the Ryan-Einot-Gabriel-Welsch multiple-range test (alpha=.05). RESULTS The OCP of each alloy varied with the condition (as-cast or heat-treated) and electrolyte used. Corrosion resistance was similar for the 4 alloys tested. For cyclic polarization, all alloys showed active-passive or spontaneous passive behavior in nearly all electrolytes. During some reverse scans, the 3 high-palladium alloys displayed 3 or 5 anodic peaks. No positive hysteresis was observed for any of the alloy/electrolyte combinations evaluated. CONCLUSION The corrosion resistances of the 3 high-palladium alloys in simulated body fluid and oral environments were comparable to that of the gold-palladium alloy. The similar corrosion resistance for the 3 high-palladium alloys was attributed to their high noble metal content and theorized stable structure at the submicron level. Selective corrosion of different phases and elements, surface enrichment of palladium, and adsorption of species are possible corrosion mechanisms. The cyclic polarization results suggest that none of the 4 alloys would be prone to pitting or crevice corrosion under in vivo conditions, but crevice conditions should nonetheless be avoided for these alloys in the oral environment.
Rohlin Distance and the Evolution of Influenza A Virus: Weak Attractors and Precursors

The evolution of the hemagglutinin amino acids sequences of Influenza A virus is studied by a method based on an informational metrics, originally introduced by Rohlin for partitions in abstract probability spaces. This metrics does not require any previous functional or syntactic knowledge about the sequences and it is sensitive to the correlated variations in the characters disposition. Its efficiency is improved by algorithmic tools, designed to enhance the detection of the novelty and to reduce the noise of useless mutations. We focus on the USA data from 1993/94 to 2010/2011 for A/H3N2 and on USA data from 2006/07 to 2010/2011 for A/H1N1. We show that the clusterization of the distance matrix gives strong evidence to a structure of domains in the sequence space, acting as weak attractors for the evolution, in very good agreement with the epidemiological history of the virus. The structure proves very robust with respect to the variations of the clusterization parameters, and extremely coherent when restricting the observation window. The results suggest an efficient strategy in the vaccine forecast, based on the presence of “precursors” (or “buds”) populating the most recent attractor.
Analysis of hydroxylated metabolites of PCBs (OH-PCBs) and other chlorinated phenolic compounds in whole blood from Canadian inuit.

In this study, we identified the main hydroxylated polychlorinated biphenyls (OH-PCBs) and other chlorinated phenolic compounds and we determined their relative concentrations in whole blood from 13 male and 17 female Inuit from northern Quebec, Canada, and from a pooled whole blood sample from southern Quebec. We also determined concentrations of polychlorinated biphenyls (PCBs). Total OH-PCB concentrations were variable among the Inuit samples, ranging over 2 orders of magnitude (0.117-11.6 ng/g whole blood wet weight). These concentrations were equal to and up to 70 times those found for the southern Quebec pooled whole blood sample. Geometric mean concentrations of total OH-PCBs were 1.73 and 1.01 ng/g whole blood for Inuit men and women, respectively, and 0.161 ng/g whole blood for the southern population pool. There are limited data available for comparison, but the levels of OH-PCBs in Inuit are higher than those previously reported in the literature for other populations. There was a significant correlation (p < 0.005) between OH-PCBs and PCBs (r = 0.84) and both correlated significantly (p < 0.005) with age (r = 0.68 and 0.78, respectively). The ratio of OH-PCBs to PCBs was lower in Inuit (0.11) than in the southern Quebec pool (0.33). There is no apparent explanation for the difference. There was considerable variability in the congener pattern of the identified OH-PCBs. The main metabolite, 4-OH-CB109 (4-OH-2,3,3',4', 5-pentachlorobiphenyl), constituted 12-62% of the total OH-PCBs in the samples. Pentachlorophenol (PCP) was the dominant phenolic compound in blood, constituting 46% (geometric mean) of the total quantitated chlorinated phenolic compounds. PCP concentrations in Inuit blood ranged from 0.558 to 7.77 ng/g on a wet weight basis. All but two Inuit samples had lower concentrations than the southern Quebec pool (6.29 ng/g). The possible role of OH-PCBs in mediating PCB-induced adverse effects needs to be investigated further. ImagesFigure 1Figure 2Figure 3Figure 4
Energy Balance during Taekwondo Practice in Elite Male Taekwondo Players

Background The goal of this study was to evaluate energy expenditure and dietary intake of nutrients during Taekwondo practice in elite Korean male Taekwondo players. Methods: Elite Korean male high school (high school player: HP; n = 59) and college players (college player: CP; n = 58) wore an accelerometer to measure energy expenditure and recorded their daily dietary intake for nutritional analysis over the course of five days. Results: Nutritional adequacy ratios for total energy (0.82), vitamin C (0.97), calcium (0.78), and folate (0.75) were below recommended levels for all players. When comparing daily nutrient intake and energy expenditure between HP and CP, the HP group had significantly higher total calorie intake (402.7 kcal, p < 0.001), calcium (126.3 mg, p = 0.018), phosphorus (198.0 mg, p = 0.002), iron (1.3 mg, p = 0.002), and vitamin B2 (0.4 mg, p < 0.001) than the CP group. Although there was no significant difference in the estimated energy requirement during Taekwondo practice, the total energy expenditure (151.2 kcal, p = 0.001), total activity counts (130,674 counts, p = 0.038) and energy expenditure during Taekwondo practice (257.7 kcal, p < 0.001) were significantly higher in the HP than in the CP. Conclusion: The results indicate that a sports nutrition program based on energy balance is necessary to achieve optimal health and performance in elite male Taekwondo players.
Statistical Studies of the Verbal Agreements and their Impact on the Synoptic Problem *

The patterns of verbal agreement between the gospels have long been considered a key for solving the synoptic problem, and a subdiscipline within gospel source criticism of tabulating and interpreting these patterns of agreement has slowly emerged in the name of gathering the most objective evidence available. Studies of the verbal agreements have steadily grown in their sophistication (esp. in combinatory analysis), as well as in their appreciation for the nature of the gospel text as something more than a mere compilation. The question of whether this approach can substantially further the field, however, has yet to be answered. This article surveys and critiques all published statistical studies of the verbal agreements known to the author.
Triadic interactions in families with preterm children: a comparative study with children born at term

The relationship between parents and infants born preterm is multifaceted and could present some relational patterns which are believed to predict psychological risk more than others. For example, insensitive parenting behavior has been shown to place very preterm children at greater risk of emotional and behavioral dysregulation. The main objective of this study was to compare the quality of family interactions in a sample of families with preterm children with one of the families with at-term children, exploring possible differences and similarities. The second aim of this research was to consider the associations among family interactions and parental empowerment, the child’s temperament, parenting stress, and perceived social support. The sample consisted of 52 children and their families: 25 families, one with two preterm brothers with preterm children (mean 22.3 months, SD 12.17), and 26 families with children born at term (mean 22.2 months, SD 14.97). The Lausanne Trilogue Play procedure was administered to the two groups to assess the quality of their family interactions. The preterm group was also administered the Questionari Italiani del Temperamento, the Family Empowerment Scale, the Multidimensional Scale of Perceived Social Support, and the Parenting Stress Index – Short Form. Differences in the quality of family interactions emerged between the preterm and at-term groups. The preterm group showed significantly lower quality of family interactions than the at-term group. The parenting stress of both parents related to their parental empowerment, and maternal stress was also related to the partner’s parental empowerment. Social support had a positive influence on parenting stress, with maternal stress also related to perceived social support from the partner, which underscores the protective role of the father on the dyad.

Toward a Developmental Criminology

The study of criminality will benefit from a developmental perspective that employs analyses of within-subject changes. A review of the evidence shows continuity in offending between adolescence and adulthood and continuity between prepubertal conduct problems and later offending. Three developmental processes of offending include activation, aggravation, and desistance. A variety of documentation indicates that developmental sequences can be identified for conduct problems, substance use, and delinquency. Quantitative and qualitative changes occur in the course of offending. Understanding developmental processes provides valuable insights into formulating strategies for longitudinal studies that can help to discriminate better between correlates and causes of crime. Examining developmental processes as youngsters grow older, such as increases in physical strength and motor skills, the emergence of personality traits, sexual maturation, and greater opportunities for crime commission, provides important contextual information for studies of offending. Developmental theories have direct implications for the prevention of offending and treatment of offenders.
Cytomegalovirus and Epstein-Barr Virus in Breast Cancer

Findings of polymerase chain reaction (PCR) studies of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) and breast cancer vary, making it difficult to determine whether either, both, or neither virus is causally associated with breast cancer. We investigated CMV and EBV in paired samples of breast cancer and normal breast tissue from 70 women using quantitative PCR. A serum sample from each woman was tested for CMV and EBV IgG. To place our results in context, we reviewed the existing literature and performed a meta-analysis of our results together with previous PCR studies of EBV, CMV, and breast cancer. Of the serology samples, 67 of 70 (96%) were EBV IgG positive and 49 of 70 (70%) were CMV IgG positive. QPCR detected EBV in 24 (34%) of the tumour and 9 (13%) of the paired normal specimens and CMV in 0 (0%) of the tumour and 2 (3%) of the paired normal specimens. Our findings, together with earlier results summarised in the meta-analysis, suggest several possibilities: variable findings may be due to limitations of molecular analyses; ‘hit and run’ oncogenesis may lead to inconsistent results; one or both viruses has a role at a later stage in breast cancer development; infection with multiple viruses increases breast cancer risk; or neither virus has a role. Future studies should focus on ways to investigate these possibilities, and should include comparisons of breast cancer tissue samples with appropriate normal tissue samples.
Why are Middle-Aged People so Depressed? Evidence from West Germany

Does happiness vary with age? The evidence is inconclusive. Some studies show happiness to increase with age (Diener et al. 1999; Argyle 2001). Others hold that the association is U-shaped with either highest depression rates (Mroczek and Christian 1998; Blanchflower and Oswald 2008) or highest happiness levels occurring during middle age (Easterlin 2006). Current studies suffer from two shortcomings. Firstly, they do not control for three confounding time variables: age, period and cohort effects. Secondly, all empirical research lacks a theoretical explanation as to why age affects happiness. The purpose of our analysis is to contribute to closing both of these research gaps. A social investment model frames the dynamics of happiness across the life-span. The empirical test draws on West German panel data that followed individuals from 1984 to 2005. Descriptive analysis shows a cubic age function with the lowest level at middle age. However, hierarchical three-level variance component models (Rabe-Hesketh and Skrondal 2005), find significant differences across pre-war and post-war cohorts, baby boomers and offspring of the baby bust as well as deviations during reunification. Yet, cohort and period effects account for less than 10% of the variance. (Un)happiness in midlife is more strongly determined by gender-specific occasional influences and individual characteristics. Both define objective and subjective returns of professional and personal life investments. These social investment decisions date back to early adulthood and bear a high risk of failure during midlife. Unforeseen consequences and long-term private and professional commitments make it costly to adjust, but at the same time new investments may pay off in a pro-longed future. This dilemma turns many middle-aged people into “frustrated achievers”.
