Abstract: we analyzed the reproductive status, ovarian development, daily survival rate, and length of the gonotrophic cycle in females of anopheles ( kerteszia ) cruzii dyar & knab, to determine how these factors influence the risk of malaria transmission in the coastal region of the state of paraná, southern brazil. in the palmito state forest, paranaguá, females were captured at dawn and dusk by aspiration, bimonthly from december 2006 through march 2007. a total of 2,268 females were captured, of which 454 were dissected. of these, 48% were parous, 50% not reproductive, 73% in christopher and mer stages i and ii, 23% in stages iii to v, 55% nulliparous, 14% uniparous, and 11% had blood in their midgut. daily survival was 0.24 ± 0.03 overall, 0.51 ± 0.04 for females captured at dusk, and 0.25 ± 0.03 for those captured at dawn. the davidson equation for calculation of the gonotrophic cycle was inadequate for an. cruzii populations. females captured at dusk had a higher survival rate than those from dawn, which means that more females of the dusk population enter the parasite extrinsic cycle. the continuous activity and abundance of a. cruzii in the palmito state forest suggests that the conditions are very favorable for its development, with a potential for participation in the protozoan's transmission cycle.
Dinamica da Araucaria angustifolia (Bert.) O. Ktze. e Ilex paraguariensis St. Hil. em duas florestas de araucária no estado do Paraná, Brasil / Dynamic of Araucaria angustifolia (Bert.) Ktze. e Ilex paraguariensis St. Hil. in two araucária forest located in the state of Paraná, Brazil

Abstract: Neste trabalho, estudaram-se o crescimento volumétrico, a mortalidade e o recrutamento das espécies Ilex paraguariensis St. Hil. e Araucaria angustifolia (Bert.) O. Ktze em duas florestas de araucária localizadas no Estado do Paraná, Brasil. Os dados foram coletados em 4 parcelas permanentes, no município de S o Jo o do Triunfo e 8 nos municípios de General Carneiro e Coronel Domingos Soares, medidas a partir de 1998, todas com 1,00 hectare cada, exceto uma com 0,5 hectare em S o Jo o do Triunfo. As espécies foram analisadas por meio de indicadores estruturais e dinamicos: IVI, abundancia, área basal, volume, distribui o diamétrica, distribui o espacial, recrutamento, mortalidade e incrementos. Os resultados demonstraram que em sete anos de dinamica estrutural a espécie Araucaria angustifolia (Bert.) O. Ktze, teve decréscimo acentuado na sua posi o de importancia na comunidade já a espécie Ilex paraguariensis St. Hil., de maneira geral, manteve seu IVI nas comunidades. Observou-se na comunidade de S o Jo o do Triunfo, a espécie Araucaria angustifolia (Bert.) O. Ktze, passa por una diminui o de densidade, porque a mortalidade está sendo maior que o recrutamento, entretanto na área de General Carneiro o quadro é inverso, está ocorrendo um aumento na densidade total para a espécie. Já para a Ilex paraguariensis St. Hil., a densidade tem aumentado gradativamente. Assim, evidenciou-se que as duas florestas, com rela o às duas espécies analisadas, apresentaram comportamentos diferentes em termos de recrutamento, mortalidade e crescimento volumétrico e a provável causa para isso tenha sido a diferen a no histórico de explora o no passado, bem como outros fatores relacionados ao sítio. A área de General Carneiro e Coronel Domingos Soares apresentou maior crescimento para estas duas espécies que a área de S o Jo o do Triunfo, com valor incremento volumétrico periódico anual (IPA vol) médio de 2,163 m3/ha.ano-1 e 0,608 m3/ha.ano-1 para araucária e erva-mate, respectivamente, enquanto que em S o Jo o do Triunfo o crescimento foi de 1,891 m3/ha.ano-1 e 0,255 m3/ha.ano-1, respectivamente. Concluiu-se que, perdurando o atual quadro, estas duas espécies presentes nestas florestas estudadas dever o continuar a se desenvolver em termos estruturais nos próximos anos.

Abstract: The genetic variability of populations of Aedes (Stegomyia) aegypti (Linnaeus, 1762) is often low due to the intense selection pressure caused by chemical control measures. In this study, we evaluated the susceptibility of larvae and adults of this mosquito to chemical insecticides, the frequency of the Val1016IIe mutation, and the genetic variability of the mitochondrial ND4 gene fragment in the urban area of Foz do Igua u, Paraná. The populations of A. aegypti in the southern and central regions of the city were resistant to the diagnostic dose of temephos 0.0162 ppm. Additionally, we detected difference in susceptibility in the northern population. The resistance ratios (RR95) were 3.8, 4.1, and 4.6 for the populations in the north, central, and south of the city, respectively. The entire population of A. aegypti in Foz do Igua u is resistant to pyrethroids. The mortality rates are as follows: 72.2% for cypermethrin (CD: 146 mg i.a./m2) and 57% for deltamethrin (CD: 18 mg i.a./m2). These results corroborate the hypothesis that the mutated 1016Ile allele is present in all analyzed strata. Out of the 234 samples genotyped for the Val1016Ile mutation, 15% were homozygous dominant for the wild allele (Val/Val), 62% were heterozygous (Va/Ile) and 23% were homozygous for the recessive mutation (Ile/Ile). With respect to the genetic variability of the mitochondrial ND4 gene fragment, 93% of the sequences analyzed belonged to haplotype 1, and 7% belonged to haplotype 2. The genetic diversity was low, the fixation index was not significant, and gene flow was high. The control of A. aegypti in Foz do Igua u using temephos and pyrethroids may be compromised because of the reduced vector susceptibility. Populations of A. aegypti, that undergoes a sudden reduction in effective population size and become resistant to pyrethroids may differ from the original population in vector capacity.

Abstract: glycogen supercompensation is one of the adaptations induced by physical training. to potentiate this phenomenon, many athletes use supraphysiological doses of anabolic androgenic steroids (aas). the purpose of this study was to evaluate the effects of nandrolone and aerobic physical exercise in rats, on body weight, plasmatic triglycerides levels, blood glucose and glycogen content. male wistar rats were randomly divided into 4 groups: sedentary + vehicle (sv), trained + vehicle (tv), sedentary + aas (saas) and trained + aas (taas) (n = 7-14/group). they received i.m. injections of nandrolone or vehicle for 9 weeks, and during the same period trained rats were submitted to aerobic exercise. data were analyzed by two-way anova and tukey tests (p < 0.05). the groups saas, tv and taas presented lower body weight than the sv group (saas: 339 ± 10 = tv: 342 ± 14 = taas: 332 ± 6 < sv: 398 ± 9 g). physical training significantly reduced plasmatic concentration of triglycerides [(tv: 46 ± 4 = taas: 44 ± 3) < (sv: 104 ± 1 = saas: 101 ± 6 mg/dl)] and of hepatic glycogen [(tv: 3,38 ± 0,57 = taas: 2,62 ± 0,34) < (sv: 4,95 ± 0,11 = saas: 4,43 ± 0,23 mg/100 mg)] and increased the cardiac glycogen concentration [(tv: 0,38 ± 0,04 = taas: 0,42 ± 0,03) > (sv: 0,2 ± 0,02 = saas: 0,21 ± 0,02 mg/100 mg)]. blood glucose and soleus glycogen reserves remained unaltered. the use of supraphysiological doses of nandrolone did not potentiate any of the effects obtained in response to aerobic physical training.

Abstract: through amniocentesis carried ou in 90 high-risk pregnant women a critical study of the citology of the amniotic fluid by the nile-blue sulphate method was undertaken. the results were compared with those obtained by using creatinine and simple x-rays of the abdomen as well as their relationship with the foetal-age of the babies when born (calculated by the lubchenco and capurro tables). the nile-blue sulphate method is of considerable value due to conditions in brazil and presents a lower percentage of errors than others. for evaluation of foetal maturity, however, one should use all methods simultaneously, along with clinical assessment.

Abstract: genetic variability of a population of aedes aegypti from paraná, brazil, using the mitochondrial nd4 gene. to analyze the genetic variability of populations of aedes aegypti, 156 samples were collected from 10 municipalities in the state of paraná, brazil. a 311 base pairs (bp) region of the nadh dehydrogenase subunit 4 (nd4) mitochondrial gene was examined. an analysis of this fragment identified eight distinct haplotypes. the mean genetic diversity was high (h = 0.702; p = 0.01556). amova analysis indicated that most of the variation (67%) occurred within populations and the fst value (0.32996) was highly significant. fst values were significant in most comparisons among cities. the isolation by distance was not significant (r = -0.1216 and p = 0, 7550), indicating that genetic distance is not related to geographic distance. neighbor-joining analysis showed two genetically distinct groups within paraná. the dna polymorphism and amova data indicate a decreased gene flow in populations from paraná, which can result in increased vectorial competence.
QUANTIFICATION OF FIXED CARBON STORED IN PINUS PLANTATION IN THE DOMAIN OF THE MIXED OMBROFILA FOREST IN PARANA STATE.
Ana Paula Dalla Corte,Carlos Roberto Sanquetta
CERNE , 2007,
Abstract: This paper, developed in the Mixed Araucaria Forest (F.O.M.), in Parana State, aimed at detecting the main carbon stock spots in forest plantations in the limits of the ecosystem, as well as estimating the amount of carbon being fixed by their biomass of these stands. A total of 22 CBERS and LANDSAT satellite imagery scenes were used for this purpose. Most of them came from 2004. The visual interpretation of the forest plantation stands inside the study area (F.O.M.) was carried out taking into account several criteria. Stand growth and yield simulation were carried out for pine plantations, the dominant genus in the study site, by using the SISPINUS software. Hence, it was possible to relate stand volume in different age classes to the biomass amount fixed by them. Subsequently, the spatial information was treated and summarized by meso-region adopted by the Paraná Sate Government, so that the comprehension of the carbon values became easier. The reforestation area interpreted summed 516,163.58 ha, and the total carbon stock was estimated at 26,726,950.2 t C or 97,999,708.2 t of CO2 equivalent.
