Inbreeding studies in Brasilian schoolchildren

Abstract: We present results of comparisons between consanguineous and control couples and their children in Southern Brasil. Multiple regression, t-test and χ2 analyses were applied to the data. The following variables were investigated; Parents: structure of first cousin marriages, latitude and longitude of birthplaces, cohabitation time, rurality, marriage age, occupation, number of liveborn children, and frequency of twinning. Schoolchildren: clinical data as classified into 24 discontinuous traits, each one subdivided into two categories (number and severity), and seven continuous traits (weight, height, pulse rate, respiratory rate, systolic pressure, diastolic pressure, and temperature); nutrition indices and biotype; family names; intelligence tests and school performances; birth order, age, hair color, hair type, eye color, and skin color; twinning in the sibship, and infant mortality among sibs of the propositi. Our study showed a) nonrandomness of consanguineous marriages as detected on structural, racial, geographical, and temporal levels; b) a heavy mutational load of about 1.5 lethons acting on infant mortality; c) no inbreeding effect on morbidity in general (with a possible exception of “ear morbidity”, including hearing deficit); d) a modest inbreeding depression on height (a decrease of 2 cm with an increase of 10% of inbreeding); e) a suggestion of inbreeding depression on “intelligence”.

The use of sugar in infected wounds

Abstract: As we knew that hiperconcentrated solutions possibly have a bacterial killing effect by osmotic action, acting across bacteria wall and membrane the authors in this issue report their experience with the use of sugar in the treatment of wound-breaking and scars. The results are shown and accepted as satisfatory, and we display the low cost of the treatment and the possibility of being used any hospital structure and even at home, by the patient himself

Evidências preliminares de estratificação vertical de postura de ovos por alguns culicidae (diptera), em floresta no município de manaus - amazonas

Abstract: Resumo Foram instalados criadouros artificiais e 0; 1,0; 6,0 e 11 metros de altura, numa floresta de terra firme em Manaus, Amazonas. O presente trabalho descreve um tipo de plataforma para estudo de estratificacao vertical para postura de ovos de Culicidae e os resultados obtidos. Foram coletadas 10 especies de Culicidae: Limatus durhami, Limatus flavisetosus, Culex bonnei, Culex mathesoni, Culex urichii, Culex originator, Trichoprosopon d. digitatum, Toxorhychites h. haemorrhoidalis, Wyeomyia aphobema e Orthopodomyia sp. As seis primeiras especies foram coletadas em todos os niveis de alturas e suas populacoes diminuiram conforme a elevacao. Tr. d. digitatum so foi encontrado ate 6 metros de altura e sua populacao aumentou conforme a elevacao do criadouro. To. h haemorrhoidalis foi coletado a 1 e 6 metros, Orthopodomyia sp. somente a 6 metros e W. aphobema somente a 11 metros de altura.

QUANTIFICAÇÃO E USO DE CARACTERES ANATÔMICOS E FISIOLÓGICOS DE FOLHAS NA DETERMINAÇÃO DE EFICIÊNCIA HÍDRICA EM CLONES DE Hevea spp.

Abstract: Resumo Em trabalhos anteriores os autores em epifgrafe determinaram caracteres anatomo-ecologicos de folhas para sugerir possivel comportamento fisiologico de diversos clones de Hevea spp e outros generos de interesse economico O presente trabalho correlaciona caracteres anatomicos com parâmetros fisiologicos, visando a determinar a dependencia dos segundos com os primeiros Foram determinados diversos indices anatomicos nas folhas de seis clones de Hevea spp e correlacionados com medicoes fisiologicas nos mesmos, tais como, potencial hidrico, resistencia estomatica e eficiencia fotossintetica Os resultados sugerem uma estreita correlacao entre a estrutura da folha e seu comportamento, indicando que a anatomia pode ser utilizada eficientemente como indicador de tolerância a seca, eficiencia fotossintetica e consequentemente, produtividade Com base nos indices de correlacao, tornou-se possivel situar os parâmetros anatomicos, fisiologicos e os fisio-anatomicos, relativos a magnitude de importância para diagnostico de plantas com resistencia a desidratacao e a seca, sendo possivel tambem, situar parâmetros relacionados com a produtividade Todos os indices foram tomados com base na eficiencia fotossintetica de folhas submetidas a diferentes graus de hidratacao Notou-se tambem que os parâmetros corrigidos foram invariavelmente, mais decisivos quando comparados com os resultados analisados sem correcoes

"Bone Wax" implantation into dental sockets. Clinical and histological evaluation in patients.

Abstract: “Bone Wax” (Ethicon) intra-alveolar implantation was evaluated clinically and histologically in patients after maxillary medial incisor extraction. Twenty-four patients were used forming control and treated groups. Clinical and radiographic examinations were made on the 4th to the 63rd postoperative day. Osseous biopsies were taken on the 7th, 21st, 42nd, and 63rd postoperative days.According to the results of this experiment, we think it is possible to conclude that “Bone Wax” is an effective hemostatic agent. It was well tolerated by the surrounding tissues when implanted into the dental socket, although, it promoted a moderate inflammatory reaction, delaying the healing of the alveolar apical third.

Estudo cariotipico em duas especies de cuculiformes americanos (aves)

Abstract: Two species of birds of the Cuculidae Family, Playa cayana (Phaenicophaeinae) and Crotophaga major (Crotophaginae), captured in Manaus (AM, Brazil) region have been cytogenetically studied The chromosomes were preparared for 4 hours in culture using bone narrow cells The karyotypic analyses were done by convencional methods from which numerical, morphological and metrical data of the chromosomes were drawn The mean size of the macrochromosomes, the Relative Lengths (PR) and Arm Ratlos (B) were calculated on the basis of the measurements obtained A system on decreasing order of size was used to arrange the chromosomes, designating each chromosome individually The macrochromosomes were morphologically classified according to Levan et al (1964) All chromosomes that had PR equal or bigger than 4% were considered as macrochromosomes P cayana has 2n complement of 76 chromosomes, from which 22 are considered as macrochromosomes The Z chromosome is submetacentric and the second of the karyotype, however the W is subtelocentric and the eleventh in size C major has 64 chromosomes, from which 22 are macro-chromosomes The Z chromosome is metacentric and the fourth of the karyotype, but the W chromosome is submetacentric and the sixth in size

O ciclo básico nas universidades do estado do Paraná visão critica e proposta de reestruturação

Abstract: O presente trabalho tem como objetivo verificar e avaliar ate que ponto o Ciclo Basico das Universidades do Estado do Parana estao exercendo as funcoes que a legislacao lhe conferiu e se estao correspondendo as expectativas da sociedade. Espera-se que seus resultados contribuam para uma tomada de posicao por parte das comunidades universitarias quanto a este importante aspecto da Reforma Universitaria. O trabalho e composto de algumas consideracoes preliminares, tratamento teorico do problema, conceituacao, procedimentos metodologicos resultados, analise dos principais problemas encontrados, uma proposta de reestruturacao e conclusoes. A proposta de reestruturacao consta de cinco partes referente especificamente a funcoes e objetivos, estrutura e funcionamento, conteudo, metodologia e estrategias de acompanhamento e avaliacao. Das conclusoes devem ser evidenciadas as seguintes: 1) — O Ciclo Basico nao foi uma ideia assumida pelas Universidade do Estado do Parana, sendo uma inovacao imposta pela legislacao nao envolveu as comunidades universitarias; 2) - Os docentes de modo geral estao preocupados em ensinar a "sua disciplina" nao se preocupando com uma "filosofia de ensino", com "uma filosofia da ciencia" ou ate com a destinacao de "sua disciplina" no contexto da formacao global do aluno; 3) - Reformas de ensino nao se restringem as simples substituicoes de disciplinas nos planos curriculares. Ha necessidade de reflexao para se chegar a um pacto comunitario. Nada adiantam as reformas se as bases nao estao convecidas de sua validade.

Ocorrência da doença meningocócica em japoneses e descendentes no município de Londrina, Paraná, Brasil (1965-1975)

Abstract: In the case of Japanese and their descendants living in the municipality of Londrina, State of Parana, the morbidity of meningococcic disease was about seven times lower than for the rest of the population, the death rate having been nil during both endemic and epidemic phases. A review of medical and hospital records, covering registered cases, showed no diagnoses of meningococcic disease in 75% of patients of Japanese origin or in 20% of samplings of non-Japanese patients. The possible relationship of socioeconomic and cultural (nutritional) factors, as regards above observations is discussed.
