Abstract |
Bullying was investigated as a group process, a social phenomenon taking place in a school setting among 573 Finnish sixth-grade children (286 girls, 287 boys) aged 12–13 years. Different Participant Roles taken by individual children in the bullying process were examined and related to a) self-estimated behavior in bullying situations, b) social acceptance and social rejection, and c) belongingness to one of the five sociometric status groups (popular, rejected, neglected, controversial, and average). The Participant Roles assigned to the subject were Victim, Bully, Reinforcer of the bully, Assistant of the bully, Defender of the victim, and Outsider. There were significant sex differences in the distribution of Participant Roles. Boys were more frequently in the roles of Bully, Reinforcer and Assistant, while the most frequent roles of the girls were those of Defender and Outsider. The subjects were moderately well aware of their Participant Roles, although they underestimated their participation in active bullying behavior and emphasized that they acted as Defenders and Outsiders. The sociometric status of the children was found to be connected to their Participant Roles. © 1996 Wiley-Liss, Inc. |

Abstract |
Während einer fünftägigen Gotthardüberquerung im Sommer 2016 haben drei Maultiere als Tragtiere mit einer Gepäcklast von je 80 kg rund 94,46 Kilometer und 3�364 Höhenmeter bewältigt. Die Leistungsanforderung wurde anhand der Erholungswerte der Vitalparameter Herzfrequenz, Atemfrequenz und Körpertemperatur, sowie durch kontinuierliche Herzfrequenzmessung während der Belastung evaluiert. Die Bestimmung der Glucokortikoid- Metabolit Konzentration im Kot diente zur Einschätzung des Stresslevels der drei Maultiere. Die Erholungswerte der Herzfrequenzen der drei Maultiere lagen während allen Trekkingetappen in einem Bereich, der nicht auf eine Leistungsüberforderung schliessen liess. Anhand der kontinuierlichen Herzfrequenzaufzeichnung bei einem der Maultiere konnte gezeigt werden, dass die physische Leistungsanforderung im Ausdauerbereich lag. Wie als normale physiologische Reaktion des Körpers nach einer fünftägigen körperlichen Belastung erwartet, stieg Stresslevel gemessen an den Glucokortikoid- Metaboliten im Kot gegen Ende des Trecks bei allen Maultieren an. In der vorliegenden Studie konnte gezeigt werden, dass die Maultiere während des Gotthardtrecks ausdauernd belastbar waren, ohne durch die Anstrengung beeinträchtigt zu sein, die schon historisch von Maultieren abverlangt wurde.[
Durant une traversée du Gothard de cinq jours pendant l�été 2016, trois mulets ont été employés comme animaux de bât pour porter une charge de 80 kg sur 94,46 km, avec un dénivelé de 3364 m. Les exigences de performance ont été évaluées à partir des valeurs de récupération des paramètres vitaux (fréquence cardiaque, fréquence respiratoire et température corporelle) et de la fréquence cardiaque durant l�effort. La concentration en métabolites glucocorticoïdes dans le crottin a permis d�estimer le niveau de stress des trois animaux. Durant toute la durée du trek, les valeurs de récupération de la fréquence cardiaque des trois mulets étaient comprises dans un intervalle n�indiquant aucun effort excessif. La mesure constante des pulsations cardiaques a montré que l�intensité des performances physiques de ces animaux ne sortait pas de leur zone d�endurance. Comme on pouvait s�y attendre, le niveau de stress mesuré par le biais des métabolites glucocorticoïdes a augmenté chez tous les mulets à la fin du trek, réaction physiologique normale du corps après un effort de cinq jours. La présente étude a montré que durant un trek sur le Gothard, les mulets ont fait preuve d�endurance et de résistance, sans altération due à l�effort que l�on exige traditionnellement de leur part.][Nell�estate del 2016 tre muli impiegati come animali da soma hanno attraversato il Gottardo portando un carico di 80 kg ciascuno e percorrendo in cinque giorni un percorso di circa 94,46 chilometri con un dislivello di 3364 metri. La prestazione è stata valutata sulla base dei valori di recupero dei parametri vitali (frequenza cardiaca, frequenza respiratoria, temperatura corporea) e misurando costantemente la frequenza cardiaca sotto sforzo. Il livello di stress dei tre muli è stato valutato in funzione della concentrazione di metaboliti glicocorticoidi riscontrata nelle feci. In tutte le tappe del trekking i valori di recupero della frequenza cardiaca registrati nei muli rientravano in un intervallo che non lasciava supporre un sovraccarico. Sulla base della registrazione costante della frequenza cardiaca di uno dei tre muli è stato possibile dimostrare che l�intensità dello sforzo fisico non superava il loro intervallo di resistenza. Come previsto, verso la fine del trekking la concentrazione di metaboliti glicocorticoidi nelle feci di tutti e tre i muli indicava un aumento del livello di stress; si tratta di una reazione fisiologica normale dopo uno sforzo fisico di cinque giorni. Questo studio ha dimostrato che lo sforzo sopportato dai muli per portare un carico attraverso il Gottardo, un compito da secoli richiesto a questi animali, rientrava nel loro intervallo di resistenza e non ha avuto ripercussioni negative sul loro fisico.][In the summer of 2016, three pack mules, each carrying a load weighing 80kg, accompanied a 94.46km trek across the Gotthard Pass with a total altitude difference of 3,364m. The mules� performances were evaluated by measuring vital recovery parameters such as heart- and respiratory rates and body temperature, and by continuous heartrate monitoring during the trek. The stress levels of the animals were estimated by determining glucocorticoid metabolite levels in their faeces. Throughout the trekking days, recovery heartrates lay within a range which indicated that the animals were not being overworked. The continuous heartrate monitoring of one of the mules showed that its physical performance lay within the endurance zone. As expected, glucocorticoid metabolite levels were elevated in the faeces of all the mules � a normal physiological response after five consecutive days of exercise. The study shows the mules as being capable of performing at an endurance level during the Gotthard trek with no adverse affects on their health � a performance which was historically expected of the animals.] |

Abstract |
Virus vector studies were conducted in the States of Durango, Chihuahua, and Tamaulipas, Mexico, in June and July 1972. Apparently only a low level of Venzuelan equine encephalitis (VEE) virus transmission to equines occured at the time of the study, and the infection was restricted to areas which had not experienced overt activity during the preceding year. The low level of infection was associated with a scarcity of mosquitoes. The IB (epidemic) strain of VEE virus was isolated from two pools of Anopheles pseudopunctipennis (Theo.) and the blood of one symptomatic equine. The low mosquito population, the relatively few equine cases observed, and the absence of reports of VEE human disease from the outbreak area suggested VEE virus persistence through a low-level mosquito-equine transmission cycle. Other studies have already indicated that wild vertebrates play no more than a minor role in outbreaks of epidemic VEE. Mosquito collections made in areas of the states of Durango, Chihuahua, and Tamaulipas, where considerable epidemic activity of VEE had occurred in 1971, failed to reveal evidence of VEE virus persistence. Twenty-nine ioslations of other arboviruses were also made in these studies: including 22 of St. Louis encephalitis virus (SLE), 2 of Flanders virus, 1 of Turlock virus, 1 of Trivittatus virus of the California Group, 1 of western equine encephalitis virus (VEE), and 2 (from Santa Rose) which possibly represent a hitherto unknown virus in the Bunyamwera Group. These are the first reports of SLE virus isolations from mosquitoes in Mexico, and the first demonstration of Trivittatus, VEE Turlock and Flanders viruses in Mexico from any source. |

Abstract |
A cross-sectional seroepidemiologic study was carried out between 1985 and 1990 in 1,567 heterosexual intravenous drug users who had been seen at the AIDS Regional Reference Center in Palermo, Italy, to evaluate the rate of human immunodeficiency virus type 1 (HIV-1) seroprevalence in this group and its long-term trend. Sixty serum samples collected from drug users in 1980 and 1983, before the founding of the Center (1985), were tested as well. Some demographic and behavioral risk factors were studied in a subgroup of intravenous drug users enrolled in 1985, 1987, and 1990 for their possible association with HIV-1. These factors were also studied in relation to hepatitis B virus infection, since both viruses share the same modes of spread. These drug users had a higher prevalence of markers for hepatitis B virus than of HIV-1 antibodies, and the prevalence rates in sera collected declined over time for both infections. The presence of both antibodies to HIV-1 and markers for hepatitis B virus was independently associated with the age of the drug user, the duration of drug use, and the year of serum collection. Antibodies to HIV-1 were observed more frequently in females than in males. No relation was found between education or employment status and the presence of HIV-1 antibodies or hepatitis B virus markers. Although new HIV-1 infections still occur, the decline in seroprevalence observed at the end of the 1980s might be related to modifications in social behavior among newer drug users, partial exhaustion of the susceptible population, and increasing risk awareness in more experienced users. |

Abstract |
BACKGROUND: Peroxisome proliferator-activated receptor gamma (PPARgamma) ligands improve human hypertension. However, the mechanism and site of this effect remains unknown, confounded by PPARgamma expression in many cell types, including endothelial cells (ECs). METHODS: To evaluate the vascular role of PPARgamma we used a conditional null mouse model. Specific disruption of PPARgamma in ECs was created by crossing Tie2-Cre+ transgenic (T2T+) and PPARgamma-floxed (fl/fl) mice to generate PPARgamma (fl/fl)T2T+ (PPARgamma E-null) mice. Conscious 8- to 12-week-old congenic PPARgamma (fl/fl)Cre- (wild type) and PPARgamma E-null mice were examined for changes in systolic blood pressure (BP) and heart rate (HR), untreated, after 2 months of salt-loading (drinking water), and after treatment for 3 months with high fat (HF) diet alone or supplemented during the last 2 weeks with rosiglitazone (3 mg/kg/d). RESULTS: Untreated PPARgamma E-nulls were phenotypically indistinguishable from wild-type littermates. However, compared to similarly treated wild types, HF-treated PPARgamma E-nulls had significantly elevated systolic BP not seen after normal diet or salt-loading. Despite sex-dependent baseline differences, salt-loaded and HF-treated PPARgamma E-nulls of either sex had significantly elevated HR versus wild types. Interestingly, rosiglitazone improved serum insulin levels, but not HF diet-induced hypertension, in PPARgamma E-null mice. CONCLUSIONS: These results suggest that PPARgamma in ECs not only is an important regulator of hypertension and HR under stressed conditions mimicking those arising in type 2 diabetics, but also mediates the antihypertensive effects of rosiglitazone. These data add evidence supporting a beneficial role for PPARgamma-specific ligands in the treatment of hypertension, and suggest therapeutic strategies targeting ECs may prove useful. |

Abstract |
This paper reports the first isolation of Jamestown Canyon (JC) virus from coastal California and the results of tests for antibody to JC virus in mammals living in coastal California. The virus isolation was made from a pool of 50 Aedes dorsalis females collected as adults from Morro Bay, San Luis Obispo County, California. The virus isolate was identified by two-way plaque reduction-serum dilution neutralization tests done in Vero cell cultures. Sera from the mammals were tested for antibody to JC virus by a plaque-reduction serum dilution neutralization method. A high prevalence of JC virus-specific antibody was found in horses and cattle sampled from Morro Bay. This finding is additional evidence for the presence of a virus antigenically identical or closely related to JC virus in Morro Bay and indicates that the vectors of the virus in Morro Bay feed on large mammals. A high prevalence of virus-specific antibody was also found in horses sampled from Marin and San Diego counties. This finding suggests that viruses antigenically identical or closely related to JC virus are geographically widespread in coastal California. |

Abstract |
A population of adult Anopheles freeborni near Sheridan, CA was sampled daily during 13 August-7 September 1984. Data on abundance, trophic status, and gonotrophic age were recorded. Abundance and gonotrophic age data were analyzed to estimate daily survivorship and gonotrophic cycle length. Daily survivorship for unfed mosquitoes was estimated to be 0.72 with a gonotrophic cycle of 6 days duration. Daily survivorship for bloodfed mosquitoes was estimated to be 0.74 with a gonotrophic cycle of 4 days. The 2 day difference in gonotrophic cycles between unfed and bloodfed mosquitoes was the result of the period required for maturation and mating of teneral females. In 1986, an incage release of field-collected females estimated survivorship at 0.75 per day. Precipitin tests of 1,338 blood-engorged mosquito abdomens indicated that bovids, horses, rabbits, and canids comprised 92% of bloodmeals; no bloodmeals of human origin were detected. |
