The eusociality continuum

Eusocial societies are traditionally characterized by a reproductive division of labor, an overlap of generations, and cooperative care of the breeders' young. Eusociality was once thought to occur only in termites, ants, and some bee and wasp species, but striking evolutionary convergences have recently become apparent between the societies of these insects and those of cooperatively breeding birds and mammals. These parallels have blurred distinctions between cooperative breeding and eusociality, leading to calls for either drastically restricting or expanding wage of these terms. We favor the latter approach. Cooperative breeding and eusociality are not discrete phenomena, but rather form a continuum of fundamentally similar social systems whose main differences lie in the distribution of lifetime reproductive success among group members. Therefore we propose to array vertebrate and invertebrate cooperative breeders along a common axis, representing a standardized measure of reproductive variance, and to drop such (loaded) terms as ''primitive'' and ''advanced'' eusociality. The terminology we propose unites all occurrences of alloparental helping of kin under a single theoretical umbrella (e.g., Hamilton's rule). Thus, cooperatively breeding vertebrates can be regarded as eusocial, just as eusocial inverbrates are cooperative breeders. We believe this integrated approach will foster potentially revealing cross-taxon comparisons, which are essential to understanding social evolution in birds, mammals, and in sects.

Insufficient coping behavior under chronic stress and vulnerability to psychiatric disorders

Epidemiological data indicate that 75% of subjects with major psychiatric disorders have their onset in the age range of 17-24 years. An estimated 35-50% of college and university students drop out prematurely due to insufficient coping skills under chronic stress, while 85% of students receiving a psychiatric diagnosis withdraw from college/university prior to the completion of their education. In this study we aimed at developing standardized means for identifying students with insufficient coping skills under chronic stress and at risk for mental health problems. A sample of 1,217 college students from 3 different sites in the U.S. and Switzerland completed 2 self-report questionnaires: the Coping Strategies Inventory "COPE" and the Zurich Health Questionnaire "ZHQ" which assesses "regular exercises", "consumption behavior", "impaired physical health", "psychosomatic disturbances", and "impaired mental health". The data were subjected to structure analyses by means of a Neural Network approach. We found 2 highly stable and reproducible COPE scales that explained the observed inter-individual variation in coping behavior sufficiently well and in a socio-culturally independent way. The scales reflected basic coping behavior in terms of "activity-passivity" and "defeatism-resilience", and in the sense of stable, socio-culturally independent personality traits. Correlation analyses carried out for external validation revealed a close relationship between high scores on the defeatism scale and impaired physical and mental health. This underlined the role of insufficient coping behavior as a risk factor for physical and mental health problems. The combined COPE and ZHQ instruments appear to constitute powerful screening tools for insufficient coping skills under chronic stress and for risks of mental health problems.

Northern Ireland Point Prevalence Survey of Hospital-acquired Infections and Antimicrobial Use 2012

The PHA�coordinated Northern Ireland's participation in ECDC's National Prevalence Survey on�Hospital-Acquired Infections & on Antimicrobial Use. Hospitals in Northern Ireland participated in data collection between May and June 2012.This report provides a snapshot of the levels of hospital-acquired infections (HAI) and levels of antimicrobial use (AMU) in hospitals in Northern Ireland during 2012.There have been three previous HAI PPS surveys and the last survey was carried out in 2006. It is difficult to compare each survey as the data was collected in a different way. However, after making allowances, there was an overall drop in HAI prevalence of 18% from 2006 to 2012.The PPS data collection was undertaken by hospital teams between May and June 2012 (one hospital deferred data collection until September 2012 because of a move to a new hospital); 16 hospitals surveyed 3,992 eligible patients. The median age of all patients was 66 years. A total of 383 (10 per cent) children under 16 years of age were surveyed.�Key results from this year's survey:The prevalence of HAI was 4.2%. A total of 166 patients were diagnosed with an active HAI with 3 patients having more than one infection.When comparing ward specialties, HAI prevalence was highest for patients in adult intensive care units (ICUs) at 9.1 per cent, followed by care of the elderly wards at 5.7%.The most common types of HCAI were respiratory infections (including pneumonia and infections of the lower respiratory tract) (27.9 per cent of all infections), surgical site infections (18.9 per cent) and urinary tract infections (UTI) (11.8 per cent).Since the last PPS in 2006 there has been a reduction in MRSA infections - from 0.9 per cent �of the hospital population to less than 0.1 per cent in patients; and a five-fold reduction in C. difficile infections (from 1.1 per cent to 0.2 per cent).The prevalence of antimicrobial use was 29.5%.Most antibiotic use (60 per cent) in hospitals was in patients receiving treatment for infections which commenced in the community. Eleven percent of surgical prophylaxis was prescribed for greater than one day.��

Patterns in the situated activity of substance use in the careers of elite doping athletes

Objectives This article presents a psychological approach to substance use in sport using a dynamic and situated activity framework. The aim was to analyze the various relationships between activity and the consumption of substances during the sporting life course of athletes who recognized doping violation. Design Data were collected from secondary sources and biographical and self-confrontational interviews to build traces of the past activity. Method Twelve doping athletes or those admitting to having used banned substances volunteered to participate. The data were coded and compared to identify typical activities and their intrinsic dynamics. Results Six activities were identified: "Agree to use," "Drop out of a non-viable state," Return to a former state," "Prevent a potential deficiency," "Maintain an acquired state," and "Balance the sporting life with substance use," comprising 11 patterns. Conclusions The athletes' activity embedded substance use in reciprocal relationships that consisted of freezing, exploring and exploiting fields of possible actions created and offered by the situation dynamics. Recommendations for situated and dynamic prevention are provided.

Pathogenesis-related proteins and the jasmonate signaling pathway

Résumé Etant une importante source d'énergie, les plantes sont constamment attaquées par des pathogènes. Ne pouvant se mouvoir, elles ont développé des systèmes de défense sophistiqués afin de lutter contre ces prédateurs. Parmi ces systèmes, les voies de signalisation mettant en jeu des éliciteurs endog8nes tels que les jasmonates permettent d'induire la production de protéines de défense telles que les protéines dites "liées à la pathogénèse". Les gènes codant pour ces protéines appartiennent à des familles multigéniques. Le premier but de cette thèse est d'évaluer le nombre de ces gènes dans le génome d'Arabidopsis thaliana et d'estimer la part de ce système de défense, dépendant de la voie de signalisation des jasmonates. Nous avons défini un cluster de seulement 1S gènes sur 266, "liés à la pathogénèse", exclusivement régulés par les jasmonates. De multiples membres des familles des lectines de type jacaline et des inhibiteurs de trypsines semblent dépendre du jasmonate. Présente dans tous les systèmes immunitaires des eucaryotes, la famille des défensines est une famille très intéressante. Chez Arabidopsis thaliana, 317 protéines similaires aux défensines ont été définies, cependant seulement 15 défensines (PDF) sont bien annotées. Ces 15 défensines sont séparées en deux groupes dont un semble avoir évolué plus récemment. Le second but de cette thèse est d'étudier ce groupe de défensines à l'aide de la bioinformatique et des techniques de biologie moléculaire (gêne rapporteur, PCR en temps réel). Nous avons montré que ce groupe contenait une défensine acide intéressante, PDF1.5, qui semblait avoir subi une sélection positive. Cette protéine n'avait encore jamais été étudiée. Contrairement à ce que nous pensions, nous avons établi que cette protéine pouvait avoir une activité biologique liée à la défense. Ce travail de thèse a permis de préciser le nombre de gènes "liées à la pathogénèse" induits par la voie des jasmonates et d'apporter des éléments de réponse sur la question de la redondance des gènes de défense. En conclusion, même si de nombreuses familles de gènes intervenant dans la défense sont bien définies chez Arabidopsis, il reste encore de nombreuses études à faire sur chacun de ces membres. Abstract Being an important source of energy, plants are constantly attacked by herbivores and pathogens. As sessile organisms, they have developed sophisticated defense responses to cope with attack. Among these responses, signalling pathways, using endogenous elicitors including jasmonates (JA), allow the plant to induce the production of defense proteins such as pathogenesis-related (PR) proteins. The genes encoding these proteins belong to multigenic families. The first goal of this thesis was to evaluate the number of PR genes in the genome of Arabidopsis thaliana and estimate how much of this plant defense system was dependent on the jasmonate signaling pathway in leaves. Surprisingly a cluster of only 1S genes out of 2ó6 PR genes was exclusively regulated by JA. Multiple members of the jacalin lectin and trypsin inhibitor gene families were shown to be regulated by JA. Present in all eukaryotic immune systems, defensins are an attractive PR family to study. In Arabidopsis thaliana, 317 defensin-related proteins have been found but just 1S defensins (i.e. PDF family) are well annotated. These defensins are split into 2 groups. One of these groups may have appeared and diversified recently. The second goal of this thesis was to study this defensin gene group combining bioinformatic, reporter gene and quantitative PCR techniques. We have shown that this group contains an interesting acidic defensin, PDF1.S, which seems to have undergone positive selection. No information was known on this protein. We have established that this protein may have a biological activity in plant defense. This thesis allowed us to define the number of PR genes induced by the jasmonate pathway and gave initial leads to explain the redundancy of the PR genes in the genome of Arabidopsis. In conclusion, even if many defense gene families are already defined in the Arabidopsis genome, much work remains to be done on individual members.

Tendencias de la mortalidad por enfermedades cardiovasculares en Andalucía entre 1975 y 2004

Background: Cardiovascular diseases are ranked among the leading causes of death in the industrialized countries. This study is aimed at ascertaining the mortality trends by ischemic heart disease (IHD) and cerebrovascular diseases (CVD) in Andalusia within the 1975-2004 period. Method: Based on the official IHD and CVD death statistics and the related populations, the gross rates (GR) and age-adjusted rates (TS) and the Potential Years of Life Lost (PYLL) were calculated. To quantify the trends and their change points, a joinpoint regression analysis was made. Results: The number of IHD deaths for females rose from 2,086 deaths in 1975 to 3,336 in 2004, the TS having dropped from 74.29 to 50.94 deaths/100,000 females, the PYLL having dropped from 173.65 years to 90.56 years/100,000 females. The number of deaths for males rose from 2,854 deaths in 1975 to 4,085 in 2004, the TS having dropped from 147, 67 to 104.96 deaths /100,000 males. The PYLL showed a like behaviour from the first to the last year of the series, showing values of 716.46 and 460.04 years / 100,000 males. For the IHD in females, the number of deaths in absolute numbers dropped from 4,712 to 4,221, the TS having dropped from 166.00 to 62.08 deaths in females, and the PYLL from 338.08 to 87.63 years / 100,000 females. For males, the number of deaths dropped from 3,714 to 2,951, the TS from 206.88 deaths /100,000 males in 1975 to 76.12 /100,000 males in 2004, and the PYLL dropping from 533.12 to 182.38 years / 100,000 males. Conclusions: The trend in mortality due to IHD was not constant either among females or males, although it has always been a downward trend, the drop being statistically significant. The drop in the CVD has been such a major one that both the absolute numbers and the gross rates are lower for the most recent years that the first years in the series studied despite the aging of Andalusia’s population.

Circulating natural killer and γδ T cells decrease soon after infection of rhesus macaques with lymphocytic choriomeningitis virus

Rhesus macaques infected with the WE strain of lymphocytic choriomeningitis virus (LCMV-WE) serve as a model for human infection with Lassa fever virus. To identify the earliest events of acute infection, rhesus macaques were monitored immediately after lethal infection for changes in peripheral blood mononuclear cells (PBMCs). Changes in CD3, CD4, CD8 and CD20 subsets did not vary outside the normal fluctuations of these blood cell populations; however, natural killer (NK) and γδ T cells increased slightly on day 1 and then decreased significantly after two days. The NK subsets responsible for the decrease were primarily CD3-CD8+ or CD3-CD16+ and not the NKT (primarily CD3+CD56+) subset. Macaques infected with a non-virulent arenavirus, LCMV-Armstrong, showed a similar drop in circulating NK and γδ T cells, indicating that this is not a pathogenic event. V³9 T cells, representing the majority of circulating γδ T cells in rhesus macaques, displayed significant apoptosis when incubated with LCMV in cell culture; however, the low amount of cell death for virus-co-cultured NK cells was insufficient to account for the observed disappearance of this subset. Our observations in primates are similar to those seen in LCMV-infected mice, where decreased circulating NK cells were attributed to margination and cell death. Thus, the disappearance of these cells during acute hemorrhagic fever in rhesus macaques may be a cytokine-induced lymphopenia common to many virus infections.

Analysing trends in cardiovascular mortality: some methodological points.

This paper comments on the drop in coronary heart disease mortality observed in Switzerland among middle-aged men since the mid-seventies. Several methodological points are made regarding the consistency of this decline (relationships with mortality from other causes), and the reasons for this drop (possible change in population mix). It is suggested that a more complete use of vital statistics is still possible and that this can provide useful clues for the assessment and the interpretation of mortality trends in the field of cardiovascular epidemiology.

Guiding blind T cells and dendritic cells: A closer look at fibroblastic reticular cells found within lymph node T zones.

It is within the T cell rich zone of secondary lymphoid organs (SLO) that dendritic cells (DC) present the captured pathogens to recirculating T cells in order to activate the rare antigen-specific T cells. While we have made considerable progress in understanding the biology of mobile hematopoietic cells found within SLO, notably DC and lymphocytes, we still have a lot to learn about the sessile stromal cells. This review is focused on the recent progress made in our understanding of the fibroblastic reticular stromal cells that form the 'niches' within the T zone.

Decreased levels of uric acid after oral glucose challenge is associated with triacylglycerol levels and degree of insulin resistance

Hyperuricaemia is one of the components of metabolic syndrome. Both oxidative stress and hyperinsulinism are important variables in the genesis of this syndrome and have a close association with uric acid (UA). We evaluated the effect of an oral glucose challenge on UA concentrations. The study included 656 persons aged 18 to 65 years. Glycaemia, insulin, UA and plasma proteins were measured at baseline and 120 min after an oral glucose tolerance test (OGTT). The baseline sample also included measurements of total cholesterol, triacylglycerol (TAG) and HDL-cholesterol. Insulin resistance was calculated with the homeostasis model assessment. UA levels were significantly lower after the OGTT (281.93 (sd 92.19) v. 267.48 (sd 90.40) micromol/l; P < 0.0001). Subjects with a drop in UA concentrations >40.86 micromol/l (>75th percentile) had higher plasma TAG levels (P = 0.0001), baseline insulin (P = 0.02) and greater insulin resistance (P = 0.034). Women with a difference in plasma concentrations of UA above the 75th percentile had higher baseline insulin levels (P = 0.019), concentration of plasma TAG (P = 0.0001) and a greater insulin resistance index (P = 0.029), whereas the only significant difference in men was the level of TAG. Multiple regression analysis showed that the basal TAG levels, insulin at 120 min, glycaemia at 120 min and waist:hip ratio significantly predicted the variance in the UA difference (r2 0.077). Levels of UA were significantly lower after the OGTT and the individuals with the greatest decrease in UA levels are those who have greater insulin resistance and higher TAG levels.

How to increase the population of a Phlebotomus perniciosus (Diptera: Psychodidae) colony: a new method

The sandfly Phlebotomus perniciosus is the most widespread vector of Leishmania infantum in Spain. Laboratory colonisation represents the most feasible source of information on the biology of these insects, but in conducting any study, the density of individuals in the colony may drop to such an extent that it is sometimes difficult to recover the initial population levels. A new technique was tested for the recovery of sandfly eggs in three different colonies; the recovery rate was studied by comparing the standard method of mass rearing with this new method of colony management. The results demonstrate a mean increase of 18.4% in adult production, a growth in colony productivity that justifies the inclusion of this process in the routine maintenance of any colony of sandflies.

Middle and Late Jurassic carbon stable-isotope stratigraphy and radiolarite sedimentation of the Umbria-Marche basin (Central Italy)

A continuous carbon isotope curve from Middle-Upper Jurassic pelagic carbonate rocks was acquired from two sections in the southern part of the Umbria-Marche Apennines in central Italy. At the Colle Bertone section (Terni) and the Terminilletto section (Rieti), the Upper Toarcian to Bajocian Calcari e Marne a Posidonia Formation and the Aalenian to Kimmeridgian Calcari e Marne a Posidonia and Calcari Diasprigni formations were sampled, respectively. Biostratigraphy in both sections is based on rich assemblages of calcareous nannofossils and radiolarians, as well as some ammonites found in the upper Toarcian-Bajocian interval. Both sections revealed a relative minimum of delta(13)C(PDB) close to + 2 parts per thousand in the Aalenian and a maximum around 3.5 parts per thousand in early Bajocian, associated with an increase in visible chert. In basinal sections in Umbria-Marche, this interval includes the very cherry base of the Calcari Diasprigni Formation (e.g. at Valdorbia) or the chert-rich uppermost portion of the Calcari a Posidonia (e.g at Bosso). In the Terminilletto section, the Bajocian-early Barthonian interval shows a gradual decrease in delta(13)C(PDB) values and a low around 2.3 parts per thousand. This part of the section is characterised by more than 40 m of almost chart-free limestones and correlates with a recurrence of limestone-rich facies in basinal sections at Valdorbia. A double peak with values of delta(13)C(PDB) around + 3 parts per thousand was observed in the Callovian and Oxfordian, constrained by well preserved radiolarian faunas. The maxima lie in the Callovian and the middle Oxfordian, and the minimum between the two peaks should be near the Callovian/Oxfordian boundary. In the Terminilletto section, visible chert increases together with delta(13)C(PDB) values from the middle Bathonian and reaches peak values in the Callovian-Oxfordian. In basinal sections in Umbria-Marche, a sharp increase in visible chert is observed at this level within the Calcari Diasprigni. A drop of delta(13)C values towards + 2 parts per thousand occurs in the Kimmeridgian and coincides with a decrease of visible chert in outcrop. The observed delta(13)C positive anomalies during the early Bajocian and the Callovian-Oxfordian may record changes in global climate towards warmer, more humid periods characterised by increased nutrient mobilisation and increased carbon burial. High biosiliceous (radiolarians, siliceous sponges) productivity and preservation appear to coincide with the delta(13)C positive anomalies, when the production of platform carbonates was subdued and ceased in many areas, with a drastic reduction of periplatform ooze input in many Tethyan basins. The carbon and silica cycles appear to be linked through global warming and increased continental weathering. Hydrothermal events related to extensive rifting and/or accelerated oceanic spreading may be the endogenic driving force that created a perturbation of the exogenic system (excess CO2 into the atmosphere and greenhouse conditions) reflected by the positive delta(13)C shifts and biosiliceous episodes.

Bi-ventricular axial micropump: impact on blood cell integrity.

BACKGROUND AND OBJECTIVE: Off-pump coronary artery bypass grafting has stimulated the development of micro-pumps designed to prevent the hemodynamic instability induced by heart luxation for the exposure of target vessels of the posterior wall. Impella (Aachen, Germany) developed micro-pumps with a miniaturized propeller system for both sides of the heart. The aim of this study was to analyze the impact of both pumps working together on blood cell integrity. MATERIALS AND METHODS: Both right and left-sided micro-pumps were implanted in 5 calves (body weight, 72_4 Kg) during 3 h. Blood samples for hematology and hemolysis parameters were drawn hourly. RESULTS: Both pumps performed well with a flow of 3.6 L +/- 0.3 L during the 3 h of the experiment with stable hemodynamic conditions. Mixed venous oxygen saturation was 63.4 +/- 15.2% at baseline and 63.8 +/- 16.3% at the end of the experiment (P = ns). Red cell count, LDH and free plasma hemoglobin were 6.7 +/- 2.1 x 10(12)/L, 1807 +/- 437 IU/L, and 32 +/- 9 mg/L at baseline vs. 6.1 +/- 2.1 x 10(12)/L, 1871 +/- 410 IU/L, and 52 +/- 9 mg/L at the end of the experiment (P = ns for all comparisons). Platelet count exhibited a non-significant drop (872 +/- 126 vs. 715 +/- 22 x 10(9)/L). CONCLUSIONS: This double pump system based on the Archimed screw principle is hematologically well tolerated under conditions of prolonged cardiac assist.
