Dificultades en la integración y cooperación de los cuerpos policiales de América Latina en la lucha contra el narcotráfico. Estudio de caso: AMERIPOL

La presente investigación analiza los principales retos que afectan la cooperación e integración de los cuerpos policiales latinoamericanos en la lucha contra el narcotráfico. Para realizar dicho análisis se toma como caso de estudio AMERIPOL, organización creada en el año 2007 y que actualmente constituye el único mecanismo de cooperación policial en el hemisferio americano. Se considera que la cooperación e integración de los cuerpos policiales en la lucha contra el narcotráfico en la región enfrentan dos retos principales: la disparidad de los marcos jurídicos entre los Estados y la descoordinación política. Estos retos suponen la existencia de factores que impiden una política de cooperación conjunta contra las drogas y por tanto, el desarrollo de actitudes aislacionistas que limitan la cooperación en contra de éste flagelo

Melhoria da Prevenção e Controle do Câncer de Colo de Útero e de Mama na UBS Rodrigues, Lagoa Vermelha/RS

O cancer de mama e o segundo tipo mais frequente do cancer no mundo, o segundo que mais aparece na populaçao feminina, e que constitui a quarta causa de morte de mulheres com cancer no Brasil. O trabalho apresentado trata de uma intervençao que tem como objetivo melhorar e qualificar a atençao do cancer de colo de utero e controle de cancer de mama, na UBS Rodrigues , Lagoa Vermelha R/S. A intervençao foi realizada de abril a junho, no ano 2015, em 12 semanas. a equipe foi capacitada de acordo com o protocolo do Ministerio da Saude,na area adstrita a UBS residem 1287 mulheres mais atençao a entre 25 e 64 anos de idade, e 517 mulheres entre 50 e 69 anos, tinhamos como metas cadastrar 80% das usuarias para o controle de cancer de mama e utero,, participam um total de 499mulheres durante as 12 semanas de intervençao, 363 {28%] na faixa etaria de 25 a 64 anos, e 136{26%} na faixa etaria de 50 a 69 anos.Todas as mulheres cadastradas estavam com coleta satifatoria de exame citopatologico de colo de utero nos tres meses da intervençao, alcanzando assim 100% de cobertura e todas receberam orientalçoes sobre doenças sexuaimente transmissiveis.A intervençao foi importante para o equipe , ja que as açoes foram incorporadas a rotina do serviço, a mesma reviu as atribuiçoes da equipe, viabilizando atençao a um maior grupo de pessoas, melhoria em os registros mais atençao a demanda espontanea e classificaçao de risco.Pretendemos implementar outras açoes prioritarias, como atençao a hipertensos, diabeticos, pre natal e puerperio. ,

DNA alignment and Bayesian trees of partial sequences of COI, COIII and the haemocyanin functional unit f-g of 28 octopod species

Background: Octopods have successfully colonised the world's oceans from the tropics to the poles. Yet, successful persistence in these habitats has required adaptations of their advanced physiological apparatus to compensate impaired oxygen supply. Their oxygen transporter haemocyanin plays a major role in cold tolerance and accordingly has undergone functional modifications to sustain oxygen release at sub-zero temperatures. However, it remains unknown how molecular properties evolved to explain the observed functional adaptations. We thus aimed to assess whether natural selection affected molecular and structural properties of haemocyanin that explains temperature adaptation in octopods. Results: Analysis of 239 partial sequences of the haemocyanin functional units (FU) f and g of 28 octopod species of polar, temperate, subtropical and tropical origin revealed natural selection was acting primarily on charge properties of surface residues. Polar octopods contained haemocyanins with higher net surface charge due to decreased glutamic acid content and higher numbers of basic amino acids. Within the analysed partial sequences, positive selection was present at site 2545, positioned between the active copper binding centre and the FU g surface. At this site, methionine was the dominant amino acid in polar octopods and leucine was dominant in tropical octopods. Sites directly involved in oxygen binding or quaternary interactions were highly conserved within the analysed sequence. Conclusions: This study has provided the first insight into molecular and structural mechanisms that have enabled octopods to sustain oxygen supply from polar to tropical conditions. Our findings imply modulation of oxygen binding via charge-charge interaction at the protein surface, which stabilize quaternary interactions among functional units to reduce detrimental effects of high pH on venous oxygen release. Of the observed partial haemocyanin sequence, residue 2545 formed a close link between the FU g surface and the active centre, suggesting a role as allosteric binding site. The prevalence of methionine at this site in polar octopods, implies regulation of oxygen affinity via increased sensitivity to allosteric metal binding. High sequence conservation of sites directly involved in oxygen binding indicates that functional modifications of octopod haemocyanin rather occur via more subtle mechanisms, as observed in this study.

Síndrome de Rett: estudo retrospectivo e prospectivo de 28 pacientes

From November 1982 to May 1999, 28 children with Rett syndrome were followed-up for a medium period of 6 years and 2 months. Regression of developmental milestones started at the age between 5 and 20 months. Nineteen cases of typical Rett syndrome had uneventful pre and perinatal periods, loss of previously acquired purposeful hand skills, mental and motor regression and developed hand stereotypies; sixteen had head growth deceleration and 12 gait apraxia. Nine patients were atypical cases, 2 formes frustres, 2 congenital, 3 with early seizure onset, 1 preserved speech and 1 male. Epilepsy was present in 21 patients, predominantly partial seizures and the drug of choise was carbamazepine (15 patients). In the initial evaluation most patients were distributed on Stages II and III and on follow-up on Stages III and IV. Three children died.

Influence of spawning procedure on gametes fertilization success in Salminus hilarii Valenciennes, 1850 (Teleostei: Characidae): Implications for the conservation of this species

Artificial reproduction and gamete fertilization were evaluated in Salminus hilarii wild and domesticated broodstocks. Wild and domesticated broodstocks were artificially induced to reproduction using a carp pituitary treatment. Four groups were considered: Group 1 (G1), fish caught in the wild maintained for three years in the same conditions as the domesticated broodstocks and spawned naturally; Group 2 (G2), broodstock born and raised in captivity and spawned naturally; Group 3 (G3), wild broodstocks, which were manually stripped for gamete collection and dry fertilization; and Group 4 (G4), domesticated males and females, also manually stripped. Oocytes, eggs, and larvae were sampled at different time intervals throughout embryonic development. Yolk sac absorption occurred approximately 24-29 h after hatching. Twenty-six h after hatching, the larvae mouths opened. Cannibalism was identified just 28-30 h after hatching. There was no morphological difference in embryonic development among all groups. The number of released eggs per gram of female was: G1: 83.3 ± 24.5 and G2: 103.8 ± 37.4; however, the fertilization success was lower in G2 (42.0 ± 6.37 %) compared with G1 (54.7 ± 3.02%) (P = 0.011). Hand-stripping of oocytes was not successful and the fertilization rate was zero. The reproduction of this species in captivity is viable, but it is necessary to improve broodstock management to enhance fertilization rates and obtain better fingerling production for restocking programs.

Estudo descritivo da massa óssea e fatores de risco cardiovasculares em mulheres com síndrome de Turner

A síndrome de Turner é uma das doenças genéticas mais comuns, ocorrendo em cerca de 1:2.500 recém-nascidas. Representa a forma mais freqüente de hipogonadismo hipergonadotrófico. O hipoestrogenismo é a principal causa atribuída ao aumento do risco de doenças cardiovasculares, osteopenia e osteoporose. Diante da elevada incidência dessas doenças, o objetivo deste trabalho foi analisar a densidade mineral óssea das mulheres portadoras da síndrome de Turner e verificar a presença de fatores de risco de doença cardiovascular (DCV). Foram encontrados, pelo método Dexa, 14,28 por cento das mulheres com densidade mineral óssea normal, 28,5por cento com osteopenia e 57,1por cento com osteoporose. Foi observada hipertensão em uma mulher, obesidade em outra, diabetes em duas e todas referiram ser sedentárias (sete). Ressalta-se, portanto a importância da avaliação precoce do tecido ósseo e do rastreamento dos fatores de risco de DCV, assim como o controle dos fatores modificáveis e orientações de mudança do estilo de vida com finalidade preventiva
