ABSTRACT Salinity is one of the abiotic stresses that affect gas exchange and growth of pomegranate. In this context, the application of nitrogen fertilizer through the leaves can minimize these effects. Thus, the objective of present study was to evaluate the effect of foliar nitrogen fertilization on pomegranate seedlings irrigated with brackish water. The design used was randomized blocks, in an incomplete factorial scheme (Central Composite Design) with five electrical conductivities of irrigation water - ECw (0.50, 1.15, 2.75, 4.35, and 5.00 dS m-1) and five doses of foliar nitrogen fertilization - FNF (0, 0.33, 1.15, 1.97, and 2.30 g L-1), with four replicates and two plants per experimental plot. Plant height, number of leaves, stem diameter, and gas exchange (stomatal conductance, net photosynthesis, intercellular CO2 concentration, transpiration rate, instantaneous carboxylation efficiency, instantaneous water use efficiency, and intrinsic water use efficiency) were evaluated at 60 days after the beginning of irrigation with saline water. Salinity of irrigation water negatively affects the gas exchange of pomegranate seedlings. Foliar nitrogen fertilization up to 1.31 g L-1 improves plant height and number of leaves in pomegranate seedlings under salt stress. Foliar nitrogen fertilization up to 1.59 g L-1 increases the net photosynthesis of pomegranate seedlings.

RESUMO A salinidade é um dos estresses abióticos que afeta as trocas gasosas e o crescimento de romãzeira. Neste sentido, à aplicação de adubo nitrogenado via foliar poderá minimizar estes efeitos. Com isso, o objetivo do presente estudo foi avaliar o efeito da aplicação foliar com nitrogênio em mudas de romã irrigadas com águas salobra. O delineamento utilizado foi de blocos casualizados, em esquema fatorial incompleto (Composto Central de Box), sendo cinco condutividade elétrica da água - CEa (0,50; 1,15; 2,75; 4,35 e 5,00 dS m-1) e cinco doses de adubação nitrogenada via foliar - ANF (0; 0,33; 1,15; 1,97 e 2,30 g L-1), com quatro repetições. A salinidade da água de irrigação afeta negativamente as trocas gasosas de mudas de romãzeira. A adubação nitrogenada foliar até 1,31 g L-1 melhora o crescimento em altura e no número de folhas em mudas de romãzeira sob estresse salino. Adubação nitrogenada foliar até a dose de 1,59 g L-1 aumenta a fotossíntese das mudas de romãzeira.

Abstract Medication-related osteonecrosis of the jaw (MRONJ) is characterized by bone exposure for more than eight weeks in patients who have used or been treated with antiresorptive or antiangiogenic drugs, without a history of radiation therapy or metastatic diseases in the jaws. Obesity is associated with changes in periodontal tissues and oral microbiota that are linked to bone alterations. This study aimed to analyze the influence of obesity on the development of bisphosphonate-induced osteonecrosis. The experiment randomly and simply divided 24 male Wistar rats (Rattus norvegicus) into four groups: healthy, with osteonecrosis, obese, and obese with osteonecrosis (n=6 per group). Osteonecrosis was induced through weekly intraperitoneal injection for eight weeks at a dose of 250 µg/kg of zoledronic acid in a 4 mg/5 mL solution, combined with trauma (exodontia). Obesity was induced through a high glycaemic index diet. Each group was qualitatively and quantitatively evaluated regarding the development of models and pathological anatomy of the lesions. The results were expressed in mean percentage and standard deviation and statistically analyzed using one-way analysis of variance (ANOVA) followed by Tukey's post-hoc test, with a significance level of 5% (p<0.05) to establish differences found between the groups. Animals in the osteonecrosis group and the obese with osteonecrosis group presented larger necrosis areas (averages: 172.83±18,19 µm2 and 290.33±15,77 µm2, respectively) (p<0,0001). Bone sequestration, hepatic steatosis, and increased adipocyte size were observed in the obese group (average: 97.75±1.91 µm2) and in the obese with osteonecrosis group (average: 98.41±1.56 µm2), indicating greater tissue damage in these groups (p<0,0001). All parameters analyzed (through histological, morphometric, and murinometric analyses) increased for the obese and obese with osteonecrosis groups, suggesting a possible influence of obesity on the results. However, further studies are needed to confirm the role of obesity in the possible exacerbation of osteonecrosis and understand the underlying mechanisms.

ABSTRACT The Aptian-Albian paleoichthyofauna in Brazil and Africa is quite diverse, yet their geographic patterns still require accounts. This work consists of a panbiogeographical analysis of paleoichthyofauna from Aptian-Albian through track analysis. Geographic coordinates were obtained and converted into paleocoordinates. Individual Tracks (ITs) and Generalized Tracks (GTs) were built with the aid of ArcView GIS v3.2 program using Trazos2004 extension. As a result, four GTs and tree Biogeographic Nodes (A, B and C) had been identified. GTs 1 and 2 shows two different faunas. GT3 indicates similarity between Brazil and Africa paleoichthyofauna suggesting the break-up of Gondwana as the event that separated it. GT4 represents a probable local seaway produced by transgressions. In the Node A a unique fauna was found indicating the presence of a third biota with its own characteristics. Node B is associated with the break-up of the supercontinent Gondwana. Node C was related to fauna exchange promoted by marine ingression and epicontinental seas that occurred during Aptian-Albian. We concluded that there is a relationship between the distributional patterns of biota and events such as the break-up of Gondwana, the formation of Atlantic Ocean and eustatic movements that affected South America and Africa.

ABSTRACT Clupeomorphs are found in many assemblages of the northeastern Brazil, whose ages range from the Neocomian to Paleogene. Ten species were described. Among them †Scutatuspinosus itapagipensis, a torpedo-like fish found in shales of the Marfim Formation from Bahia, remains poorly known. At first it was positioned within †Scutatuspinosinae and indicated as closely related to †Diplomystus. Diagnoses for the subfamily and genus were based on certain characters masking relationships. Recently it was placed in †Ellimmichthyiformes, but its systematic position remains controversial. We furnish additional data and restorations together with a parsimony analysis with TNT program, using 60 unordered and unweighted characters from selected species of 13 genera. Our analysis produced 12 trees with 158 steps, a consistency index (CI) of 0.44 and retention index (RI) of 0.52. Low support indices still indicate insufficient data for many taxa and uncertain status for clades. According to the majority rule consensus, †Scutatuspinosus itapagipensis is placed within a “†paraclupeine” group with †Ezkutuberezi carmenae, †Ellimma branneri, †Ellimmichthys longicostatus, and †Paraclupea chetunguensis. Its minimum age and position among †paraclupeids indicate an early history of the group older than it was thought to be, supporting a biogeographical hypothesis based on generalized track from China to northeastern Brazil during the Lower Cretaceous.

ABSTRACT †Codoichthys carnavalii is a clupeomorph fish only found in calcareous concretions of Codó Formation, State of Maranhão. It is known based on three specimens housed in the paleontological collection of the Museu de Ciências da Terra of Departamento Nacional da Produção Mineral, Rio de Janeiro. It was omitted in most of recent cladistic analyses about clupeomorphs. We revisited its anatomy furnishing new data and additional restorations. Furthermore we explored the relationships of †Codoichthys with the computer program TNT based on a matrix with 30 taxa and 60 unordered and unweight characters. Elops was used to root the tree. The strict consensus was obtained from three shortest trees (L=181; CI=0.387; RI=0.632). The monophyly of †Ellimmichthyiformes is supported by a sigmoid cleithrum and an uniquely derived predorsal scute series. Most of subgroups showed low support indices. †Sorbinichthyidae and †Horseshoeichthys appear in the most basal position, and not closely related to †Armigatus or †Diplomystus. A †Diplomystus clade is more advanced than †Armigatus and sister-group of remaining †ellimmichthyiforms. Within †Paraclupeidae, †Codoichthys is sister-group of remaining †paraclupeids (including †thorectichthyines and †paraclupeines). Within †Paraclupeinae, †Triplomystini includes a †Triplomystus clade, a sister group of †Rhombichthys plus †Tycheroichthys, and †Paraclupeini with †S. itapagipensis and all other †ellimmichthyiform taxa.

Resumo O estudo teve como propósito investigar a presença do efeito da idade relativa e a influência do quartil de nascimento na antropometria, maturação biológica e desempenho físico e técnico de jovens futebolistas. Foram amostrados 119 futebolistas do sexo masculino, sendo 74 da categoria infantil (sub-15) e 45 da categoria juvenil (sub-17). A data de nascimento dos atletas foi dividida em quatro quartis. Foram avaliadas a massa corporal, a estatura e as dobras cutâneas. A maturação biológica foi acedida através da idade esquelética, pelo método de Fels. O desempenho físico incluiu testes de força de membros inferiores, velocidade, resistência aeróbica e potência anaeróbica. O desempenho técnico foi avaliado pelas provas de controle da bola, condução da bola e precisão de chute. No geral, 65,5% dos futebolistas nasceram no primeiro semestre do ano (c2=8,069, p=0,04), porém, na análise por categoria, não houve diferença significante na distribuição das datas de nascimento por quartil quando comparado com a população de referência (sub-15: c2=6,322, p=0,10; sub-17: c2=2,339, p=0,50). A MANCOVA não revelou diferenças significantes entre os quartis na antropometria, maturação biológica e desempenho físico e técnico em ambas as categorias competitivas. Estes resultados sugerem que existe maior proporção de jovens futebolistas brasileiros nascidos nos primeiros meses do ano, mas que o EIR não constitui necessariamente uma vantagem sob o ponto de vista antropométrico, físico e técnico. Os processos individuais de maturação biológica devem ser considerados pelos técnicos na seleção dos atletas.

Abstract The study examined the presence of the relative age effect (RAE) and association between birth quartile and anthropometry, biological maturation and physical and technical performance of young Brazilian soccer players. The sample included 119 male players, 74 of U-15 category and 45 of U-17 category, which were divided into quartiles according to the birth year. Biological maturation was assessed using the method of skeletal age of Fels. Anthropometric measurements included body weight, stature and subcutaneous adiposity. Physical fitness assessment included strength tests in the lower limbs, speed, aerobic endurance and anaerobic power. Technical skills included ball control, dribbling and kicking accuracy. Overall, 65.5% of soccer players were born on the first half of the year (c2= 8.069, p = 0.04); however, in the analysis by category, there was no significant difference in the distribution of birth dates for quartile when compared with the reference population (U-15: c2=6.322, p=0.10; U-17: c2=2.339, p=0.50). MANCOVA revealed no significant differences between anthropometry, biological maturation and physical and technical performance in both competitive categories. These results suggest that there is a higher proportion of young Brazilian soccer born on the first months of the year, but that RAE does not necessarily constitute an advantage under the anthropometric, physical and technical standpoint. The process of biological maturation of individuals should be considered by coaches in the selection of athletes.

Objective To assess the morphological changes of penile vascular structures and the corpus cavernosum area in alloxan-induced diabetic rabbits. Materials and Methods Twenty male rabbits (2 months old) were divided into two groups with 10 rabbits each, the control group (CG) and the diabetic group (DG). The animals from DG received an intravenous injection of alloxan (100mg/kg) to induce the diabetes. Ten weeks after the induction of diabetes, all animals were euthanized. Two fragments of the penile shaft were harvested and samples were processed and paraffin embedded. Sections (5µm) were cut and stained for histological and immunohistochemical markers. Results Nuclear protrusion toward the lumen, and cytoplasmic vacuolization were observed in the tunica intima of the dorsal artery of the penis in DG. The thicknesses of the tunica media increased significantly in DG (p = 0.0350). It was also observed a significant increase in the area of the tunica media (p = 0.0179). There was no significant change in smooth muscle cell density in the tunica media of the dorsal artery of the penis (p = 0.0855). The collagen fiber pattern of the tunica adventitia of the dorsal artery of the penis was different between the control and diabetic groups. There was a significant decrease in the area occupied by the cavernous sinuses in DG (p = 0.0013). Conclusion Alloxan-induced diabetes mellitus in rabbits promotes important changes in penile vascular structures, thereby decreasing blood supply and affecting penile hemodynamics, leading to erectile dysfunction.

The goal of this investigation was to analyze and quantify changes of the reticular fibers in the prostatic urethra of patients with benign prostatic hyperplasia (BPH) and compare with a control group. Prostatic urethra tissue samples were obtained from ten patients (age range 65 to 79 years, mean 66) with clinical symptoms of bladder outlet obstruction who had undergone open prostatectomy. The ten control group samples (urethral tissue samples from the transitional zone) were collected from prostates obtained during autopsy of accidental death adults of less than 25 years. The Vv of the reticular fibers was determined with stereologic methods from 25 random fields per sample using the point-count method with a M-42 grid test system. The quantitative data were analyzed using the Kolmogorov-Smirnov and Mann-Whitney U tests. The Vv (mean±SD) in the control and BPH groups respectively were: 23.4± 1.8 and 30.3 ± 1.2 (0.001). BPH cause significant increase of reticular fibers in prostatic urethra.

El objetivo de esta investigación fue analizar y cuantificar los cambios de las fibras reticulares en la uretra prostática de pacientes con hiperplasia prostática benigna (HPB) y compararlo con un grupo control. Muestras de tejido de uretra prostática se obtuvieron de diez pacientes (rango de edad 65 a 79 años, media 66) con síntomas clínicos de obstrucción del tracto urinario inferior que se habían sometido a prostatectomía abierta. Las diez muestras del grupo de control (muestras uretrales de tejido de la zona de transición) se obtuvieron de próstatas durante la autopsia de sujetos adultos con muerte accidental menores de 25 años. El Vv de las fibras reticulares se determinó con métodos estereológicos de 25 campos al azar por muestra utilizando el método de valor de conteo con el sistema M-42. Los datos cuantitativos se analizaron mediante la prueba de Kolmogorov-Smirnov y Mann-Whitney U. El Vv (media ± DE) en el grupo control y BPH, respectivamente, fueron: 23,4 ± 1,8 y 30,3 ± 1,2 (0,001). La BPH causó aumento significativo de fibras reticulares en uretra prostática.

OBJETIVO: Os efeitos da hemodiluição normovolêmica com diferentes níveis de hemoglobina na perfusão esplâncnica são pouco conhecidos. Testamos a hipótese que durante a hemodiluição moderada e acentuada, os parâmetros hemodinâmicos sistêmicos e regionais e as variáveis relacionadas ao metabolismo de oxigênio não refletem a adequação da perfusão da mucosa gástrica. MÉTODOS: Vinte e um cães anestesiados com fentanil e vecurônio (16±1 kg) foram randomizados como controles (CT, n=7, sem hemodiluição normovolêmica), hemodiluição normovolêmica moderada (Ht 25±3%, n=7) ou hemodiluição normovolêmica acentuada (Ht 15±3%, n=7), pela troca isovolêmica entre o sangue total e hidroxietil amido a 6%, 20 mL/min até o hematócrito pré-estabelecido para cada grupo. Os animais foram acompanhados por 120 min após a hemodiluição normovolêmica. Durante todo o experimento foram medidos o débito cardíaco (CO, L/min), o fluxo de veia porta (PVF, mL/min), e os gradientes de CO2 veia porta-arterial e mucosa gástrica-arterial (PV-artCO2 and PCO2-gap, mmHg, respectivamente). RESULTADOS: O volume de sangue trocado foi de 33,9±3,3 mL/kg para hemodiluição normovolêmica moderada e de 61,5±5,8 mL/kg para a hemodiluição normovolêmica acentuada. A pressão arterial e os níveis de lactato sistêmico e regional permaneceram estáveis em todos os grupos. Houve aumentos iniciais de débito cardíaco e de fluxo de veia porta, tanto na hemodiluição normovolêmica moderada quanto na hemodiluição normovolêmica acentuada; o consumo de oxigênio sistêmico e regional permaneceram estáveis, principalmente por conta de aumentos na taxa de extração de oxigênio. O PCO2-gap apresentou aumento significativo apenas nos animais submetidos a hemodiluição normovolêmica acentuada. CONCLUSÃO: Ocorre estabilidade hemodinâmica global e regional tanto na hemodiluição normovolêmica moderada quanto na acentuada. Entretanto, o hematócrito de 15% induziu acidose moderada de mucosa gástrica, o que pode ser relevante em procedimentos cirúrgicos de grande porte ou no trauma.

OBJECTIVE: The net effects of acute normovolemic hemodilution with different hemoglobin levels on splanchnic perfusion have not been elucidated. The hypothesis that during moderate and severe normovolemic hemodilution, systemic and splanchnic hemodynamic parameters, oxygen-derived variables, and biochemical markers of anaerobic metabolism do not reflect the adequacy of gastric mucosa, was tested in this study. METHODS: Twenty one anesthetized mongrel dogs (16 ± 1 kg) were randomized to controls (CT, n = 7, no hemodilution), moderate hemodilution (hematocrit 2 5% ± 3%, n = 7) or severe hemodilution (severe hemodilution, hematocrit 15% ± 3%, n = 7), through an isovolemic exchange of whole blood and 6% hydroxyethyl starch, at a 20 mL/min rate, to the target hematocrit. The animals were followed for 120 min after hemodilution. Cardiac output (CO, L/min), portal vein blood flow (PVF, mL/min), portal vein-arterial and gastric mucosa-arterial CO2 gradients (PV-artCO2 and PCO2 gap, mm Hg, respectively) were measured throughout the experiment. RESULTS: Exchange blood volumes were 33.9 ± 3.3 and 61.5 ± 5.8 mL/kg for moderate hemodilution and severe hemodilution, respectively. Arterial pressure and systemic and regional lactate levels remained stable in all groups. There were initial increases in cardiac output and portal vein blood flow in both moderate hemodilution and severe hemodilution; systemic and regional oxygen consumption remained stable largely due to increases in oxygen extraction rate. There was a significant increase in the PCO2-gap value only in severe hemodilution animals. CONCLUSION: Global and regional hemodynamic stability were maintained after moderate and severe hemodilution. However, a very low hematocrit induced gastric mucosal acidosis, suggesting that gastric mucosal CO2 monitoring may be useful during major surgery or following trauma.

Considerando-se o desenvolvimento do ciclo biológico, observou-se que mais de 70% da emergência dos adultos de P. guildinii, N. viridula e E. heros ocorreu depois de terem sido acumulados em média 307,7; 753,8 e 370,3 graus-dia respectivamente, sendo as diferenças entre a data prevista e a observada de 0-3 dias para P. guildinii e N. viridula e 5-6 dias E. heros.

The study was carried out to predict, in the field, the occurrence of populational peaks of adults of Piezodorus guildinii (West.), Nezara viridula (L.) and Euschistus heros (Fabr.) (Heteroptera: Pentatomidae), using a degree-day model. Considering the development of the biological cycle, it was observed that more than 70% of adult emergence of P. guildinii, N. viridula and E. heros occurred when means of 307.7, 753.8 and 370.3 degree-day respectively had been accumulated. The differences between predicted and observed dates for emergence were 0-3 days for P. guildinii and N. viridula and 5-6 days for E. heros.

No período de vinte anos (1960-1979), os autores observaram na Clínica de Doenças Infecciosas e Parasitárias da Faculdade de Medicina da Universidade Federal do Rio de Janeiro, sediada no Pavilhão Carlos Chagas do Hospital São Francisco de Assis, 4.652 casos de esquistossomose mansoni procedentes de 18 Estados do Brasil. Entre os casos observados 87,18% eram da forma hepatointestinal e 12,82% da forma hepatoesplênica entre os quais 30 tinham a forma pulmonar associada. Adicionalmente 30 casos da forma aguda ou toxémica foram estudados no mesmo Serviço, em famílias residentes no Rio de Janeiro. Além da observação clínica e do estudo epidemiológico incluindo o perfil migratório de cada caso e da casuística como um todo, foram realizados exames complementares como hemograma, mielograma, dosagem de transaminases, provas de função hepática, eletroforese de proteínas séricas, biópsia hepática, radiografias de tórax e de esôfago, esplenoportografia, eletrocardiograma e estudos hemodinâmicos do sistema porta, do coração e da artéria pulmonar em grupos de pacientes selecionados.

A study of 4.652 schistosomiasis mansoni patients from 18 different States in Brazil, indicates a general picture of the morbidity of this disease in the country. Patients migrants (4.652) from different States were studied in the Department of Tropical Medicine of Federal University of Rio de Janeiro, between 1960 and 1979, with the following parameters: selected by a positive stool examination (sedimentation technique), clinical and epidemiological evaluation to determine the clinical form, migration pattern, age, sex and race. A routine chest X ray, E. C. G., haematologic and biochemistry tests, were performed. In a selected group of hepatosplenic cases a liver, biopsy, splenoportography and a portal hemodynamic study were done. Although some regional, familial, racial and/or individual differences in morbidity have been observed, the intensity of the primary infection and reinfections in the first two decades of life seems to be most important factors in the severity of human infection in Brazil. A direct correlation between egg out put and disease severity was observed in patientes under 30, except in negros who almost always present a mild form of the disease regardless of parasite burden. The evolutive pattern of the disease should be crefully investigated in relation to adaptation of different strains according to the host's immunological reactions and genectic constitution.
