Abstract:

A major nutritional problem to crops grown in highly weathered Brazilian soils is phosphorus (P) deficiencies linked to their low availability and the capacity of the soils to fix P in insoluble forms. Our studies examined factors that might influence P behavior in soils of the Amazon region. This study was conducted to evaluate the maximum phosphate adsorption capacity (MPAC) of the soils developed from mafic rocks (diabase), their parent materials and other factors resulting in the formation of eutrophic soils having A chernozemic horizon associated with Red Nitosols (Alfisol) and Red Latosols (Oxisol) of the Amazonian environment. The MPAC was determined in triplicates as a function of the remnant P values. The different concentrations used to determine the MPAC allowed maximum adsorption values to be reached for all soils. The Latosol (Oxisol) and Nitosol (Alfisol) soils presented higher phosphate adsorption values that were attributed to the oxidic mineralogy and high clay texture while the Chernosol (Mollisol) soils presented the lowest phosphate adsorption values.

Abstract: Myofibroblastoma (MFB) is a rare mesenchymal tumor arising in breast's soft tissue with a great variety of microscopic features that can be mistaken with a wide variety of biphasic lesions. The authors report a rare case of myofibroblastoma of the breast arising in a mammary hamartoma (MH), present a review of the clinicopathological features of these lesions, and make some diagnostic considerations. The tumour consisted of a well-circumscribed nodule. MFB component comprised about fifty percent of the lesion and was made up of bipolar spindle cells arranged in fascicular clusters separated by bands of hyalinized collagen. There were fat cells and several residual hamartoma glands intermingled and distorted in MFB area. MFB component was positive for Desmin, CD34, bcl-2, and Calponin. To the best of our knowledge, MFB has not been reported in MH, neither has any of the reports described mammary glands joined within MFB. 1. Introduction Myofibroblastoma (MFB) is a rare mesenchymal tumor arising in breast’s soft tissue [1, 2]. In 1987, Wargotz et al. [2] described a benign tumour of the breast composed of spindle cells arranged in fascicular clusters with interspersed bands of hyalinized collagen and called this lesion “myofibroblastoma”. After that, several cases have subsequently been reported, and it has become clear that MFB of the breast may exhibit a greater variety of morphological features than originally described. Glandular structures have not been described in MFB [3–9]. Mammary hamartomas (MH) comprise about 0.7% of all benign breast masses that were first described in 1928 by Prym [10], who referred to them as “mastomas”. Further cases were reported as adenolipomas and fibroadenolipomas. In 1971, Arrigoni was the first to introduce the term mammary hamartoma, that is further characterized by the variety of mature tissues they contain [11]. The authors report a case of MFB developed in MH. This very rare association may be a potential diagnostic pitfall in the spectrum of biphasic cell lesions of the breast. To our knowledge, the coexistence of MFB and MH in the same mass has not been published. 2. Case Report A 59-year-old woman presented with a solitary nodule in the left breast which was first noted on routine mammography. Left breast echography showed a sharply demarcated nodule in the breast parenchyma. A complete surgical excision of the mass was performed. Gross pathology showed a well-circumscribed, round to slightly lobulated, tan, rubbery, 2,5?cm nodule. On cut sections, a whitish tumour mass with scanty interspersed yellow areas was

Abstract: anastrepha sororcula zucchi, 1979, is a fruit fly species that can be considered a key pest to the production of guava (psidium guajava l., 1758), fruit tree which has a wide distribution in brazil. in view of the importance of this species as a natural pest of brazilian horticulture and, considering the lack of data about its biology and behavior, the aim of this paper is to obtain information about the age of sexual maturation of a. sororcula in the laboratory and to describe its reproductive behavior. the males reached sexual maturity between 7 and 18 days after emergence, with most of the individuals becoming sexually mature between 10 and 13 days of age. they exhibited signalling behavior to the females, characterized by the distension of the pleural area of the abdomen, forming a small pouch on each side, and by the protrusion of a tiny membranous pouch of rectal cuticle that surrounds the anal area. during this display, the males produced rapid movements of vibration of the wings, producing audible sounds. a droplet was liberated from the anal area during the vibration movements of the wings. after attracting the females, the males accomplished a series of elaborated movements of courtship behavior. the females reached sexual maturation between 14 and 24 days after emergence, with the majority becoming sexually mature at 19 days. the daily exhibition of sexual activities was confined almost exclusively to the period of 16:00-17:30h. a. sororcula presented a sharp protandry pattern.

Abstract: The study aimed to determine the effects of heat treatments applied to seeds of bitter yellow passionfruit (/Passiflora edulis/ Sims f. flavicarpa DEG) in the uniformity of seed germination. The experimental design was completely randomized blocks under a factorial scheme (3 x 2) +1, the factors being temperature (40, 50 and 60°C) and time of water immersion (10 and 15 minutes) plus a control (ambient temperature), with four replicates. The characteristics evaluated were: percentage of germination and speed of germination, being obtained both accumulated germination within 13 days and average germination velocity index. Concerning to cumulative germination percentage, treatments can be grouped into three groups as follows: first group, treatment T1D2 with 74.5%; second group with treatments T0, T1D1 and T2D2 with 55%, 53% and 52.5% respectively; third group with treatments T2D1, T3D1 and T3D2 with 35.5%, 17% and 13.5% respectively. Treatment with bitter passion fruit seed immersion in water heated to 40 oC for 15 minutes showed 75% germination and a better uniformity of seedlings.

Abstract: Objetivou-se com este trabalho avaliar a fixa o biológica de nitrogênio em feij o-caupi submetido a diferentes manejos da vegeta o natural, com e sem aduba o organica com esterco bovino, da savana de Roraima. O experimento foi instalado na área experimental do CCA/UFRR, em Boa Vista, Roraima. O plantio das sementes de feij o-caupi, cultivar BRS Aracê, inoculadas com Bradyrhizobium BR 3262, foi realizado em julho de 2011 e os tratamentos foram dispostos em umdelineamento experimental de blocos ao acaso em esquema fatorial (3 x 2) com quatro repeti es. O primeiro fator correspondeu ao manejo da vegeta o natural: com aplica o de glifosato, com corte da vegeta o natural e sem corte da vegeta o natural. O segundo fator correspondeu à aplica o de esterco bovino: com e sem aplica o. Aos 35 dias após o plantio foi efetuada a coleta das plantas de feij o-caupi para mensurar o número de nódulos; massa fresca e seca dos nódulos; altura da planta; número de folhas, massa fresca e seca da parte aérea; massa fresca e seca da raiz. A aplica o a lan o de esterco bovino na quantidade de 2,0 L m-2 sobre a vegeta o natural da savana de Roraima favorece o aumento do número de nódulos por planta de feij o-caupi.O manejo da vegeta o natural com o uso do glifosato, independentemente do uso do esterco, favorece a nodula o das raízese contribui com o maior crescimento e desenvolvimento da planta de feij o-caupi.This study evaluated the biological fixation of nitrogen in cowpea beans subjected to different managements of the natural vegetation of the savannah in Roraima. The experiment was done in the experimental area of the CCA/UFRR, Boa Vista, Roraima, Brazil. The planting of the BRS Aracê cowpea seeds, inoculated with Bradyrhizobium BR 3262, wasdone in July, 2011 and the treatments were arranged in factorial schemes (3 x 2) of experimental randomized blocks with fourrepetitions. The first factor was the management of natural vegetation: with the application of glyphosate, cutting the naturalvegetation and without cutting it. The second factor was the application of manure: with and without the manure. 35 days afterthe planting the cowpea plants were collected to measure the number of nodes; fresh and dry mass of the nodes; plant height; number of leaves; fresh and dry mass of the upper segment of the plant; fresh and dry mass of the root and root length. The application of manure, at the amount of 2,0 L m-2, over the natural vegetation of the savanna, favored the increase of the number of nodes per cowpea plant.

Brazilian Journal of Pharmaceutical Sciences , 2012,
Abstract: Amburana cearensis is a medicinal plant known as "cumaru". It is used in Northeast Brazil in the treatment of respiratory diseases. This was a randomized, double-blind, placebo-controlled study, with the aim of evaluating the efficacy and safety of cumaru syrup as complementary therapy in mild persistent asthma. The study consisted of 3 phases, pre-treatment, treatment and post-treatment. The primary efficacy outcome was comparison of the changes reported by patients of the cumaru and placebo groups after treatment, using the "Asthma Quality of Life Questionnaire" (AQLQ). The secondary outcome was the effect of cumaru syrup on lung function based on spirometry. The results showed that in the cumaru group, the proportion of patients who had global improvement in asthma symptoms was significantly greater (61.90%, P=0.0009) than in the placebo group (9.52%). Only the spirometric parameters Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1) showed significant intergroup differences in post-treatment (P<0.05). The hematological and serum chemistry tests performed in the pre-treatment and post-treatment showed no statistically significant differences (P>0.05). Adverse events were reported by 3 patients (14.29%) in the cumaru group and 3 patients (14.29%) in the placebo group. All adverse events were considered non-serious and mild. Amburana cearensis é uma planta medicinal conhecida como "cumaru". No Nordeste do Brasil é usada no tratamento de doen as respiratórias. Este é um estudo randomizado, duplo-cego e controlado por placebo, com o objetivo de avaliar a eficácia e seguran a do xarope de cumaru como terapia complementar da asma persistente leve. O estudo consistiu de três fases, pré-tratamento, tratamento e pós-tratamento. A variável primária para determina o da eficácia foi a compara o das mudan as referidas pelos pacientes dos grupos cumaru e placebo após o tratamento, usando o "Questionário sobre Qualidade de Vida na Asma" (QQVA). A variável secundária foi o efeito do xarope de cumaru na fun o pulmonar baseado na espirometria. Os resultados mostraram que no grupo cumaru, a propor o de pacientes com melhora global dos sintomas da asma foi significativamente maior (61,90%, P=0.0009) que no grupo placebo (9,52%). Somente os parametros espirométricos, capacidade vital for ada (CVF) e volume expiratório for ado no primeiro segundo (VEF1), mostraram diferen a intergrupo significtivas no pós-tratamento (P<0.05).
