Irregularidade do ciclo menstrual no menacme como marcador para fatores de risco cardiovasculares na pós-menopausa
Azevedo, George D.;Duarte, Joo-Marcelo B.P.;Souza, Maxwell O.;Costa-e-Silva, Thiago D.N.;Soares, Elvira M.M.;Maranh?o, Técia M.O.;
Arquivos Brasileiros de Endocrinologia & Metabologia , 2006, DOI: 10.1590/S0004-27302006000500008
Abstract: to evaluate the association between cardiovascular risk factors (cvrf) during postmenopausal years and previous menstrual irregularity during reproductive years, we performed a case-control study in 414 postmenopausal women (mean age 60.4 ± 5.5 years; bmi 25.3 ± 4.7 kg/m2). the variables assessed were: menstrual cycle characteristics at age 20-35y (independent) and records of arterial hypertension, dyslipidemia, diabetes mellitus, and coronary heart disease (dependent). statistical analysis used the chi-square test and logistic regression, adjusting for potential confounders for cardiovascular risk, with significance set at 5%. women reporting previous menstrual irregularity were associated with increased risk for some cvrf [adjusted odds ratio (or) 2.14; ci-95%= 1.02-4.48], when compared with those reporting regular menstrual cycles. stratified analysis demonstrated significant associations of previous menstrual irregularity with: arterial hypertension [or= 2.74; ci-95%= 1.39-5.41), hypercholesterolemia (or= 2.32; ci-95%= 1.17-4.59), hypertriglyceridemia (or= 2.09; ci-95%=1.10-4.33), and coronary angioplasty (or= 6.82; ci-95%= 1.44-32.18). these data suggest that a prior history of menstrual irregularity, as indicative of polycystic ovary syndrome, may be related to increased risk for cvd during postmenopausal years.

Golden Research Thoughts , 2012, DOI: 10.9780/22315063
Abstract: Soil pH, Electric Conductivity, Organic Carbon, NPK, Potassium, Sodium, Lime, are the essential nutrients, present in soil and helpful to growth of crops. Distribution of nutrients is unequal. In this paper, an attempt has been made to find out the level of nutrients and their distribution. It covers an area 75025 of hectares of agricultural land where 1 87, 937 population reside. Area covers 46, 683.87 sq hectors (34%) out of 138248.8 hectares of Baramati tahsil, where 76 % population are concentrated. Average village wise nutrient level of 400 soil samples from NLBC area of Baramati is calculated and presented graphically. It shows that NLBC area soil is Alkaline and indicates 11 % area are of high saline. Organic Carbon is high but there is not enough Nitrogen. Phosphorus and Potassium are in good condition. Villages Nimbut, Bajrangwadi and Late are in an excessive Alkaline condition of pH. Use of organic fertilizers, reducing excessive use of chemical fertilizers, green compost and wherever needed reclamation is recommended to maintain soil health.

Advances in Diagnosis of Rabies
Shankar B.P.
Veterinary World , 2009,
Abstract: Rabies is a major zoonosis for which diagnostic techniques have been standardised internationally. Laboratory techniques are preferably conducted on central nervous system (CNS) tissue removed from the cranium. Agent identification is preferably done using the fluorescent antibody test. A drop of purified immunoglobulin previously conjugated with fluorescein isothiocyanate is added to an acetone-fixed brain tissue smear, preferably made from several parts of the brain, including the hippocampus, cerebellum and medulla oblongata. For a large number of samples, as in an epidemiological survey, the immunoenzyme technique can provide rapid results (the rapid rabies enzyme immunodiagnosis). FAT provides a reliable diagnosis in 98-100% of cases for all genotypes if a potent conjugate is used, while RREID detects only genotype 1 virus. Infected neuronal cells have been demonstrated by histological tests and these procedures will reveal aggregates of viral material (the Negri bodies) in the cytoplasm of neurones. However, the sensitivity of histological techniques is much less than that of immunological methods, especially if there has been some autolysis of the specimen. Consequently, histological techniques can no longer be recommended. As a single negative test on fresh material does not rule out the possibility of infection, inoculation tests, or other tests, should be carried out simultaneously. Newborn or 3-4-week-old mice are inoculated intracerebrally with a pool of several CNS tissues, including the brain stem, and then kept under observation for 28 days. For any mouse that dies between 5 and 28 days, the cause of death should be confirmed by FAT. Alternatively, a monolayer culture of susceptible cells is inoculated with the same material as used for mice. FAT carried out after appropriate incubation will demonstrate the presence or absence of viral antigen. Wherever possible, virus isolation in cell culture should replace mouse inoculation tests. The identification of the agent can be supplemented in specialised laboratories by identifying any variant virus strains through the use of monoclonal antibodies, specific nucleic acid probes, or the polymerase chain reaction followed by DNA sequencing of genomic areas. Such techniques can distinguish between field and vaccine strains, and possibly identify the geographical origin of the field strains. Virus neutralisation assays in cell cultures are the prescribed tests for international trade. [Vet. World 2009; 2(2.000): 74-78]

Archives of Materials Science and Engineering , 2007,
Abstract: Purpose: The aim of this paper is description of the process of the crystallization of new aluminium bronzes with the complex silicides of the iron.Design/methodology/approach: Additions Cr, W, Mo and Si were introduced to create in the microstructure of the aluminium bronze of the complex silicides of the iron about high mechanical and physical proprieties to the bronze BA1044. The process of formation the microstructure of the bronze with use of the method of the thermal and derivative analysis (TDA) was analysed. The examinations under the microscope and X-ray microanalysis of the surface distribution of elements were conducted.Findings: From carried research results, that in the aluminium bronze BA1044 after addition Si, Cr, Mo and/or W the phase κFe, κNi crystallize as the complex silicides of the iron. Elements such as: Fe and Si dissolve first of all in silicides in the smaller stage in the matrix of the bronze, Mn and Ni they dissolve in matrix and silicides, Cr dissolves in the larger stage in silicides than in the matrix, W and Mo dissolve in silicides however they crystallize as nanocrystals in the metal matrix and create with her composite.Research limitations/implications: Results of investigations of aluminium bronze BA1044 and alloys after adding to him about 1% Si were introduced in the article and suitably: 1.22 % Cr; 0.82 % Mo; 0.020 % W; 0.60 % Cr, 0.17 % Mo and 0.017 % W.Originality/value: The original results of the investigations of the crystallization of the new bronzes (innovative materials and casting technologies) for which the process of arising microstructure the method TDA was not analysed so far were introduced in the article. The article possesses cognitive values not only essential for researcher but and practician-melters.

Abstract: Aluminium bronzes belong to the high-grade constructional materials applied on the put under strongly load pieces of machines, about good sliding, resistant properties on corrosion both in the cast state how and after the thermal processing. It moves to them Cr and Si in the aim of the improvement of their usable proprieties. Additions Mo and/or W were not applied so far in the larger concentration, these elements were introduced to the melts of the copper as the components of modifiers. It was worked out therefore the new kind of bronzes casting including these elements. Make additions to the Cu-Al-Fe-Ni bronze of Si, Cr, Mo and/or W in the rise of these properties makes possible. The investigations of the influence of the wall thickness of the cast on size of crystallites were conducted: the primary phase β and intermetallic phase κ and the width separates of the secondary phase α precipitate at phase boundary. It results from conducted investigations, that in the aluminium bronze BA1055 after simultaneous makes additions Si, Cr, Mo and in the primary phase β it undergoes considerable reducing size. The addition W reduce size of the grain phase β in the thin walls of the cast 3-6 mm, and addition Cr in the range of the thickness of the wall of the cast 3-6 mm it favors to reducing size the phase β, in walls 12-25 mm the growth causes it. The addition Mo does not influence the change of the size of the grain of the β phase significantly. The make addition singly or simultaneously of the Cr, Mo and W to the bronze CuAl10Fe5Ni5Si it influences the decrease of the quantity separates of the phase α on the interface boundary and of width it separates independently from the thickness of the wall of the cast. The simultaneous make addition of the Si, Cr, Mo and W it enlarges the surface of the phase κFe, κMo. The make addition to the bronze CuAl10Fe5Ni5Si of the Cr, Mo or W the quantity of crystallizing hard phase κ enlarges and the hardness HB of the bronze raises. The make addition singly the Mo or W, if also simultaneous with the addition Cr reduces their make addition it sensibility on the change of the thickness of the wall of the cast (3-25 mm) guaranteeing the possibly small fall the hardness the bronze about 22-28 HB. More far works over new multicomponent aluminium bronzes will be guided in the direction of the identification of the changes of mechanical properties of studied bronzes under the influence of the thermal processing.
A Study of Schottky Barrier Height Inhomogeneity on In/P-Silicon
B.P. Modi
Journal of Nano- and Electronic Physics , 2011,
Abstract: The current-voltage characteristics of In/p-Si Schottky diode measured over a temperature range of 120-360 K have been interpreted on the basis of thermionic emission across an inhomogenous Schottky contact. The experiment shows that the apparent barrier height Φbe increases and ideality factor decreases from 0.26 eV and 6.36 at 120 K to 0.70 eV and 1.91 at 360 K respectively. The variation of effective Schottky barrier height and ideality factor with temperature has been explained considering lateral inhomogeneties at the metal-semiconductor interface. We have also discussed whether or not the junction current has been connected themionic field emission (TFE) mechanisms.

Ciência e Tecnologia de Alimentos , 1999, DOI: 10.1590/S0101-20611999000300003
Abstract: currently, sulfites are employed on board to inhibit melanosis (blackspot) on crustaceans. however, when used in excess this chemical compound not only can cause adverse reactions in so2-sensitive individuals, but also favors the decomposition of trimethylamine oxide (tmao) into dimethylamine (dma) and formaldehyde (fa), thus compromising the quality of the product, which can be observed mainly through the texture change of the meat after cooking. this study was conducted to verify the increase of the contents of dma and fa by the excessive use of sodium metabisulfite in white shrimp (penaeus schmitti). for laboratory trials, shrimp were beheaded, washed and immersed in a 2% sodium metabisulfite solution for 10 minutes. specimens were stored either on ice and maintained for 48 hours in refrigeration, or stored in a freezer for 48 hours. samples were collected at intervals of 0, 24 and 48 hours, and analyzed for residual so2, tmao, tma, dma and fa. the immersion of shrimp in a 2% sodium metabisulfite for 10 minutes favored the decomposition of tmao which greatly increased the contents of dma and fa. the fa and dma measured in fresh shrimp was low. moreover, the storage of shrimp tails on ice resulted in a significant reduction of the tma, dma, fa and residual so2 contents compared to the specimens under frozen storage.

Ciência e Tecnologia de Alimentos , 1999,
Abstract: Currently, sulfites are employed on board to inhibit melanosis (blackspot) on crustaceans. However, when used in excess this chemical compound not only can cause adverse reactions in SO2-sensitive individuals, but also favors the decomposition of trimethylamine oxide (TMAO) into dimethylamine (DMA) and formaldehyde (FA), thus compromising the quality of the product, which can be observed mainly through the texture change of the meat after cooking. This study was conducted to verify the increase of the contents of DMA and FA by the excessive use of sodium metabisulfite in white shrimp (Penaeus schmitti). For laboratory trials, shrimp were beheaded, washed and immersed in a 2% sodium metabisulfite solution for 10 minutes. Specimens were stored either on ice and maintained for 48 hours in refrigeration, or stored in a freezer for 48 hours. Samples were collected at intervals of 0, 24 and 48 hours, and analyzed for residual SO2, TMAO, TMA, DMA and FA. The immersion of shrimp in a 2% sodium metabisulfite for 10 minutes favored the decomposition of TMAO which greatly increased the contents of DMA and FA. The FA and DMA measured in fresh shrimp was low. Moreover, the storage of shrimp tails on ice resulted in a significant reduction of the TMA, DMA, FA and residual SO2 contents compared to the specimens under frozen storage.
