Abstract: technological advances in positioning methods have enabled the development of methodologies that allow its use in a great variety of applications. one method of gnss (global navigation satellite system) positioning of high performance is the rtk (real time kinematic) whose basic principle takes advantage of the high correlation of the errors caused by ionosphere, troposphere and satellite orbit in a reference station and a nearby station of interest, besides requiring a radio link or other communication system to transmit the data from the base to the user. but as the distances increase, the correlation decreases and the performance is reduced. to reduce this problem, the concept of network stations (rtk network) was developed. such approach uses the infrastructure of a network of reference stations to provide corrections to the network users. the rtk and rtk network allows introducing the concept of integrity, widely used in navigation, in the context of geodesy. in this article, we present the concept of integrity and its use for evaluating the integrity on rtk and rtk network in the context of s?o paulo state gnss network. results showed that to guarantee the integrity displayed by hpl

Abstract: Differentiation syndrome (DS) represents a life-threatening complication in patients with acute promyelocytic leukemia (APL) undergoing induction therapy with all-trans retinoic acid (ATRA) or arsenic trioxide (ATO). It affects about 20-25% of all patients and there are no definitive diagnostic criteria. Clinically, DS is characterized by weight gain, fever not attributable to infection, respiratory distress, cardiac involvement, hypotension, and/or acute renal failure. At the histological point of view, there is an extensive interstitial and intra-alveolar pulmonary infiltration by maturing myeloid cells, endothelial cell damage, intra-alveolar edema, inter-alveolar hemorrhage, and fibrinous exsudates. DS pathogenesis is not completely understood, but it is believed that an excessive inflammatory response is the main phenomenon involved, which results in increased production of chemokines and expression of adhesion molecules on APL cells. Due to the high morbidity and mortality associated with DS, its recognition and the prompt initiation of the treatment is of utmost importance. Dexamethasone is considered the mainstay of treatment of DS, and the recommended dose is 10 mg twice daily by intravenous route until resolution of DS. In severe cases (respiratory or acute renal failure) it is recommended the discontinuation of ATRA or ATO until recovery.

Abstract: The contribution of the sternocleidomastoid branch of the occipital artery (superior arterial pedicle - SAP) to the irrigation of the sternocleidomastoid muscle (SCM) was evaluated in fresh human cadavers by injecting radiological dye and a resin for microvasculature corrosion casts. From its insertion in the mastoid process of the temporal bone, the SCM was divided into superior, medium, and inferior thirds. In most of the SCM, The SAP are formed by two longitudinal parallel branches. In all specimens, the radiological dye injected into the SAP reached or trespassed the middle part of the studied SCM. The SAP was poorly distributed in the lowermost region of the inferior third of the SCM, suggesting the contribution of other arteries or pedicles. The corrosion casts of the microvasculature showed a profuse network of microscopic vessels in those levels where the SAP was detected.

Abstract: THE granulocyte colony-stimulating factor (G-CSF) plays an important role in normal granulopoiesis. Its functions are mediated by specific receptors on the surface of responsive cells and, upon ligand binding, several cytoplasmic tyrosine kinases are activated. The cytoplasmic region proximal to the membrane of the G-CSF receptor (G-CSF-R) transduces proliferative and survival signals, whereas the distal carboxy-terminal region transduces maturation signals and suppresses the receptor's proliferative signals. Mutations in the G-CSF-R gene resulting in truncation of the carboxy-terminal region have been detected in a subset of patients with severe congenital neutropenia who developed acute myelogenous leukemia (AML). In addition, the AML1-ETO fusion protein, expressed in leukemic cells harboring the t(8;21), disrupt the physiological function of transcription factors such as C/EBPα and C/EBPε, which in turn deregulate G-CSF-R expression. The resulting high levels of G-CSF-R and G-CSF-dependent cell proliferation may be associated with pathogenesis of AML with t(8;21). Moreover, in vitro and in vivo studies demonstrated that G-CSF may act as a co-stimulus augmenting the response of PML-RARα acute promyelocytic leukemia cells to all-trans-retinoic acid treatment. Finally, in the PLZF-RARα acute promyelocytic leukemia transgenic model, G-CSF deficiency suppressed leukemia development. Altogether, these data suggest that the G-CSF signaling pathway may play a role in leukemogenesis.

Abstract: photosynthetic capacity of runner peanuts (arachis hypogaea l.) cv. iac-caiapó and cv. runner iac-886 was evaluated under controlled condition, in plants grown on pots maintained in a greenhouse, and in irrigated plants grown on soil-filled tanks made of concrete, and exposed to natural ambient condition. co2 net assimilation rate (a) response in relation to photosynthetic photon flux density (dfff) was better in controlled condition, but in both conditions the same maximum a of ca. 28 μmol m-2 s-1 was reached. under controlled condition, light saturation was about 1,000 μmol m-2 s-1 , although under natural condition, saturation occurred at higher dfff. leaf temperature between 23 and 36°c did not affect a, and leaf to air vapor pressure difference caused partial stomatal closing, decreasing a, when above 3.0 kpa. photosynthetic capacities of the two cultivars were similar. both cultivars showed good adaptation to daily changes of environmental conditions that occur during summer, showing dynamic photoinhibition of photosynthesis in the beginning of the afternoon (13-14h), as revealed by a reversible decrease in the maximum quantum efficiency (fv/fm) of photosystem ii.

Abstract: the understanding of the adsorption mechanisms of collectors is of primary importance for the optimization and, eventually, the feasibility of the flotation process. although anionic collectors are included in the main reagents used in various flotation systems, only a few studies of adsorption of these reagents in silicate flotation systems have been carried out when compared with the large number of studies developed with sparingly soluble minerals and oxides. the present work makes a concise revision of the adsorption mechanisms for the main anionic silicate collectors, carboxylic and sulfonic acids and sulfates. carboxylic acids are emphasized due to their ability to form insoluble salts with metallic cations.

Abstract: the restart metabolism of the embryo during germination is carried out by metabolic processes that culminate in root protrusion and energy supply for the initial seedling development. thus, the objective of this study was to investigate changes in the activity of the polygalacturonase and alpha-galactosidase enzymes and the mono and oligosaccharides reserves during germination of schizolobium parahyba seeds. seeds were placed in petri dishes to germinate and samples were removed periodically for analyses. the galactose levels in the embryonic axis differed significantly only between the treatment control and the eighth day sample, although continuous increase occurred until the fourth day. there was an increase in the amount of galactose in the cotyledons only on the sixth day of germination; on other days the values were similar. levels of arabinose, mannose and glucose tended to increase in the embryonic axis and the presence of xylose was not detected on the eighth day. the same sugars were not originally detected at time zero in the cotyledons, but other samples presented their highest values on the eighth day. the sucrose levels increased in the axis and cotyledons, while those of raffinose decreased in both. the stachiose concentration remained relatively constant in the axis and cotyledons until the sixth day and then decreased in the axis on the eighth day. the enzyme alpha-galactosidase was pre-formed and was reduced in its specific activity as of the second day and remaining constant until the eighth day. activity in cotyledons varied throughout the analysis period. polygalacturonase was also a pre-formed enzyme, with most of its activity in the axis. the activity in the cotyledons increased until the sixth day, reaching larger values than those of the axis, and then decreased to values below that observed in the axis.

Abstract: The objective of this study was to evaluate the occurrence of infectious and contagious diseases inherds of sheep and goats in northern Minas Gerais State, Brazil. Visits were carried out to eighteenbreeders of sheep and goats, six visits in the region of Montes Claros, three in the core production ofFrancisco Sá, two in Janaúba, two in Cora o de Jesus and five Ibiaí in the municipality, with fourcores in total production. The total number of animals in these properties was 2,052. Was carriedout through interviews, questionnaires to collect data on the occurrence of diseases and diarrheawas observed in young animals in 94.4% of the properties, caseous lymphadenitis in 88.9%, 33.3% inmastitis, foot pad dermatitis in 25.0%, conjunctivitis in 22.3%, contagious ecthyma in 11.1% and 5.55%in enterotoxemia. Only seven property held sporadic vaccination against clostridiosis. Practiceproper hygiene of premises and environments and handling young animals were not adopted.These figures are worrying, considering that the levels of occurrence of diseases was high. It is theneed for formation of a culture among producers that prophylactic measures should prevail on thehealing, because they represent higher costs and lower profit.

Abstract: The soil compaction promoted for animal trampling and traffic of machines, is one of great impediments to attainment of raised pasture productivities. However, the soil-pasture relationship studies have not taken in consideration the biological soil descompaction, as well as its effect in productivity. This study objective was to evaluate dry mass production of Tifton 85 grass in function of different soil compaction degrees and potential of structural quality recovery of an Red-Yellow Argisol, promoted by forage plant. The experiment was carried out in green house, in delineation entirely randomized, with the tifton 85 grass crop in the following degrees of compacting: 64%, 84%, 90%, 93% and 100%, gotten for the assay of Normal Proctor. The attributes had been evaluated the soil physical- hydric, least limiting water range and forage dry mass production. Tifton 85 grass recovered the structure of Red-Yellow Argisol. The soil descompaction promoted adequate soil biophysics conditions to forage development. The dry mass production increased with the cutting succession independent of initial degree of soil compaction. KEY WORDS: Biological soil descompaction, Cynodon sp., least limiting water range, recovery of pastures. A compacta o do solo, promovida pelo pisoteio animal e pelo tráfego de máquinas, é um dos grandes entraves à obten o de elevadas produtividades das pastagens. Entretanto, os estudos de rela o solo–pastagem n o têm levado em considera o a descompacta o biológica do solo, nem seus efeitos na produtividade. O objetivo deste estudo foi avaliar a produ o de massa seca do capim-tifton 85 em fun o de diferentes graus de compacta o do solo e o potencial de recupera o da qualidade estrutural de um argissolo vermelho-amarelo, promovida pela planta forrageira. Desenvolveu-se o experimento em casa de vegeta o, mediante delineamento inteiramente casualizado, com o cultivo do capim-tifton 85 nos seguintes graus de compacta o: 64%, 84%, 90%, 93% e 100%, obtidos pelo ensaio de Proctor Normal. Avaliaram-se os atributos físico-hídricos do solo, o intervalo hídrico ótimo e a produ o de massa seca da forrageira. O capim-tifton 85 recuperou a estrutura do argissolo vermelho-amarelo. A descompacta o do solo promoveu condi es biofísicas do solo adequadas ao desenvolvimento da forrageira. A produ o de massa seca aumentou com a sucess o dos cortes, independentemente do grau de compacta o inicial do solo. PALAVRAS-CHAVES: Cynodon sp., descompacta o biológica do solo, intervalo hídrico ótimo, recupera o de pastagem.
