Triatoma rubrovaria (Blanchard, 1843) (Hemiptera - Reduviidae - Triatominae) IV: bionomic aspects on the vector capacity of nymphs

Triatoma rubrovaria has become the most frequently captured triatomine species since the control of T. infestans in the state of Rio Grande do Sul (RS), Brazil. The aim of this study was to evaluate aspects of the vectorial competence of T. rubrovaria using nymphs raised in laboratory under environmental conditions of temperature and humidity and fed on mice. The average developmental period of T. rubrovaria was 180.1 days. The percentage of defecation shortly after feeding was still higher than previous studies in which samples of T. rubrovaria subjected to a slight starvation period before the blood meal were used. The obtained results support former indication that T. rubrovaria presents bionomic characteristics propitious to be a good vector of Trypanosoma cruzi to man. Therefore its domiciliary invasion process must be continuously monitored.

Quarterly analysis of Mental Capacity Act 2005, Deprivation of Liberty Safeguards Assessments (England) Quarters 1 to 3 2009/10

Hospitals and care homes are making use of new measures designed to protect people unable to give consent for their care.The Mental Capacity Act Deprivation of Liberty Safeguards were introduced by law on 1 April 2009 to provide a legal framework for depriving someone of their liberty where they are unable to give informed consent regarding their care. The statistics presented here provide the first official information about authorisations to legally detain a person using the legislation.The safeguards apply to people aged 18 and above who suffer from a mental disorder of the mind (such as dementia or a profound learning disability) and who lack capacity to give consent to the arrangements made for their care and / or treatment. The safeguards cover people in all hospitals and care homes in the statutory, independent and voluntary sectors.A rigorous, standardised assessment and authorisation process is used to ensure only appropriate use is made of the safeguards.Key facts?The number of authorisation requests were: 1,772 in quarter 1 1,681 in quarter 2 and, 1,869 in quarter 3. ?Of the total assessments completed in each quarter, a higher proportion were for females than for males ?For each quarter, around three out of four assessments were made by local authorities while the remaining ones were made by primary care trusts. ?The percentage of authorisations granted leading to someone being deprived of their liberty varied between 33.5 per cent and 50.7 per cent across quarters 1 to 3. ?At 31 December 2009 1,074 people were subject to such authorisations.Quarterly analysis of Mental Capacity Act 2005, Deprivation of Liberty Safeguards Assessments (England) Quarter 1 (0.31MB)Quarterly analysis of Mental Capacity Act 2005, Deprivation of Liberty Safeguards Assessments (England) Quarter 2 (0.31MB)Quarterly analysis of Mental Capacity Act 2005, Deprivation of Liberty Safeguards Assessments (England) Quarter 3 (0.31MB)Have your say - give us your comments on this publication��

Nous processos i formes de creixement urbà: el cas del districte industrial de Montebelluna a Itàlia

This article analyses the spatial organization of Montebelluna's industrial district (Italy) as an exemple of the dinamics of urbanization phenomenon in small urban areas. The study is divided in two parts: in the first one I present the social organisation's model of production named «industrial district» and its relation with the space, which is characterizeded by the rising of diffused urbanization settlements; in the second part I try to verify some explanatory factors pointed out by different autors in this specific area with an historical analysis of processes point of view. The diffused organisation of economic and housing activity show a change in the urban morphology

L’ article fa un repàs de l’evolució del concepte de districte industrial des de l’ òptica de l’experiència italiana. Partint de la constatació dels canvis que hi ha hagut en les formes d’organització de la producció en els tres darrers decennis, s’exposa l’evolució del model del districte industrial com a paradigma d’ Alfred Marshall, de principis del segle XX, s’ha anat enriquint a mesura que ha madurat l’ experiència districtual, que avui afronta els reptes de la globalització econòmica

Total antioxidant capacity of plasma in asymptomatic carrier state of Neisseria meningitidis

Reduction of the antioxidant capacity of plasma has been linked with the impairment of an effective immune response and so we hypothesized that the carriage rate of Neisseria meningitidis in asymptomatic subjects might correlate with the levels of antioxidants in plasma. To this end we took pharyngeal swabs from 339 children in Marquesado Basic Health Zone, Granada, Spain and in addition determined the total antioxidant capacity (TAC) in plasma samples from these subjects. The overall prevalence of N. meningitidis carriage was 5.9% (mean age 7.1 years) with rates of 10.3% in children aged 3 < or =years, 3.9% between 4 and 7 years and 2.4% in older subjects. Plasma TAC for the < or =3-year-olds was 0.13 for carriers and 1.10 for non-carrier controls (P=0.04), 0.13 for carriers aged 4-7 years (controls 0.63) and 0.28 for carriers aged >7 years (controls 0.52). We analysed the association between TAC in plasma (<0.37 - 2 S.D.) and the carrier state of N. meningitidis. In the carrier state, the odds ratio for this association (TAC in plasma <0.25) was 8.44 (95% CI 1.5-48.9). These findings may suggest a reduced immune response in the host favourable to nasopharyngeal persistence of meningococci.

Distribution of sibling species of Anopheles culicifacies s.l. and Anopheles fluviatilis s.l. and their vectorial capacity in eight different malaria endemic districts of Orissa, India

The study was undertaken in eight endemic districts of Orissa, India, to find the members of the species complexes of Anopheles culicifacies and Anopheles fluviatilis and their distribution patterns. The study area included six forested districts (Keonjhar, Angul, Dhenkanal, Ganjam, Nayagarh and Khurda) and two non-forested coastal districts (Puri and Jagatsingpur) studied over a period of two years (June 2007-May 2009). An. culicifacies A, B, C and D and An. fluviatilis S and T sibling species were reported. The prevalence of An. culicifacies A ranged from 4.2-8.41%, B from 54.96-76.92%, C from 23.08-33.62% and D from 1.85-5.94% (D was reported for the first time in Orissa, except for occurrences in the Khurda and Nayagarh districts). The anthropophilic indices (AI) were 3.2-4.8%, 0.5-1.7%, 0.7-1.37% and 0.91-1.35% for A, B, C and D, respectively, whereas the sporozoite rates (SR) were 0.49-0.54%, 0%, 0.28-0.37% and 0.41-0.46% for A, B, C and D, respectively. An. fluviatilis showed a similarly varied distribution pattern in which S was predominant (84.3% overall); its AI and SR values ranged from 60.7-90.4% and 1.2-2.32%, respectively. The study observed that the co-existence of potential vector sibling species of An. culicifacies (A, C and D) and An. fluviatilis S (> 50%) was responsible for the high endemicity of malaria in forested districts such as Dhenkanal, Keonjhar, Angul, Ganjam, Nayagarh and Khurda (> 5% slide positivity rate). Thus, the epidemiological scenario for malaria is dependent on the distribution of the vector sibling species and their vectorial capacity.

Refrigeració de les gillettes d’ una talladora industrial

L’empresa Proslit Equipment forma part del Grup Comexi i la seva activitat consisteix en la fabricació de màquines talladores de material flexible. Degut als avenços tecnològics, s’han incrementat les prestacions de les seves màquines, entre altres coses, s’ha augmentat la velocitat de tall del film fins a 800 m/min. Aquest factor afegit a condicionants com per exemple treballar amb materials gruixuts i abrasius, a temperatures ambientals elevades, etc. fa que sorgeixi una problemàtica en el tall gillette. Degut a la fricció entre el film que circula i les gillettes que el tallen, es crea una energia calorífica que fa augmentar la temperatura de les gillettes fins a tal extrem que aquestes provoquen petites fusions del plàstic, aquest s’incrusta a les gillettes que s’acaben trencant. L’objecte principal d’aquest projecte és fer una anàlisi tècnica mitjançant elements finits de la problemàtica que s’ha detectat a les màquines talladores de l’empresa Proslit Equipment, concretament de l’escalfament de les gillettes utilitzades en el sistema de tall. Es pretén crear un model teòric que s’aproximi al màxim a la realitat de manera que es pugui observar el comportament tèrmic del sistema de tall en funció de les condicions que es determinin com a més desfavorables. Una vegada s’obtinguin aquests resultats teòrics, es valoraran i es proposaran solucions

Regulation of free corticosterone and CBG capacity under different environmental conditions in altricial nestlings.

The concentration of circulating glucocorticoids is regulated in response to environmental and endogenous conditions. Total circulating corticosterone, the main glucocorticoid in birds, consists of a fraction which is bound to corticosterone-binding globulins (CBG) and a free fraction. There is increasing evidence that the environment modulates free corticosterone levels through varying the concentration of CBG, but experimental evidence is lacking. To test the hypothesis that the regulation of chronic stress in response to endogenous and environmental conditions involves variation in both corticosterone release and CBG capacity, we performed an experiment with barn owl (Tyto alba) nestlings in two different years with pronounced differences in environmental conditions and in nestlings experimentally fed ad libitum. In half of the individuals we implanted a corticosterone-releasing pellet to artificially increase corticosterone levels and in the other half we implanted a placebo pellet. We then repeatedly collected blood samples to measure the change in total and free corticosterone levels as well as CBG capacity. The increase in circulating total corticosterone after artificial corticosterone administration varied with environmental conditions and with the food regime of the nestlings. The highest total corticosterone levels were found in nestlings growing up in poor environmental conditions and the lowest in ad libitum fed nestlings. CBG was highest in the year with poor environmental conditions, so that, contrary to total corticosterone, free corticosterone levels were low under poor environmental conditions. When nestlings were fed ad libitum total corticosterone, CBG and free corticosterone did not increase when administering corticosterone. These results suggest that depending on the individual history an animal experienced during development the HPA-axis is regulated differently.
