13. DESEMPENHO DO ELETRODO DE FILME DE PALÁDIO NA DETERMINAÇÃO DE TÁLIO E CHUMBO EM AMOSTRAS DE ÁGUAS NATURAIS POR VOLTAMETRIA DE REDISSOLUÇÃO ANÓDICA COM PULSO DIFERENCIAL
The use of a palladium film electrode (PdFE) as an alternative electrode for the determination of thallium (Tl+) and lead (Pb2+) in water samples by anodic stripping voltammetry is proposed. Preliminary studies of the influence of the substrate were performed on the electrochemical behavior of PdFE prepared ex situ. Using a silver solid amalgam electrode as

14. Improvement of Solubility and Antifungal Activity of a New Aminothiophene Derivative by Complexation with 2-Hydroxypropyl-β-cyclodextrin
This study aimed to prepare a complex of 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) and 6CN10, a poorly water soluble 2-aminothiophene derivative with antifungal properties, by freeze-drying technique. The complex was characterized by thermal analysis, infrared/Raman spectroscopy, X-ray diffraction and scanning electron microscopy. In addition, we used the d

15. In vivo potential hypoglycemic and in vitro vasorelaxant effects of Cecropia glazioviistandardized extracts
ABSTRACTThe aim of this study is to investigate the effect of Cecropia glaziovii Snethl, Urticaceae, extracts on the oral glucose tolerance curve, on glycemia in alloxan-induced diabetic rats and vasorelaxant effect after the extraction process, and to standardize the extractive solutions. The effects of the process variables and their interactions were calc

16. Assessment of som (Persea bombycina) clones for resistance against Phyllosticta persae
Som (Persea bombycina) is an economically important tree used as food source by the muga silkworm, Antheraea assamensis. Phyllactinia leaf spot (PLS), caused by Phyllosticta persae, affects all som cultivars during June to September (rainy season) and is responsible for foliage losses up to 26%. Information about the effect of this disease at the farmer leve

17. Synergistic antibacterial action of β-sitosterol-D-glucopyranoside isolated from Desmostachya bipinnata leaves with antibiotics against common human pathogens
Desmostachya bipinnata (L.) Stapf, Poaceae, or Kusha in Sanskrit, is a sacred grass used extensively in Indian Vedic practices. It is well known for its medicinal value and is used in traditional Indian medicine to treat microbial infection in combination with other herbs. An effort has been made to isolate and characterize the bioactive compounds from the h

18. Marcadores do sistema hemostático e sua associação com parâmetros clínicos e laboratoriais em mulheres com síndrome dos ovários policísticos = : Markers of the hemostatic system and their association with clinical and laboratory parameters in women with polycystic ovary syndrome / Markers of the hemostatic system and their association with clinical and laboratory parameters in women with polycystic ovary syndrome
Introduction: Few studies have been conducted on hemostatic disorders in polycystic ovary syndrome (PCOS). In women with PCOS, thromboembolic risk factors such as obesity, hyperandrogenism and insulin resistance are often present, indirectly suggesting a greater probability of coagulation disorders. Objective: To evaluate some markers of the hemostatic syste

19. Estresse precoce e alterações do eixo hipotálamo-pituitária-adrenal (HPA) na depressão. / Early Life Stress and alterations of the Hypothalamic-Pituitary-Adrenal (HPA) axis in depression.
Introduction: Several studies suggest that stress in early stages of development can induce persistent changes in the ability of the Hypothalamic-Pituitary-Adrenal (HPA) axis to respond to stress in adulthood. The imbalance of cortisol has been identified as a biological correlate of depressive disorders. These abnormalities seem to be related to changes in

20. Mensurações ultrassonográficas da cisterna da glândula mamária de caprino transgênico
Milk production of transgenic does was evaluated by ultrasound measurements of the mammary gland. Two Canindé goats, which were nine months of age were used in the trial, one non-transgenic or other transgenic for hG-CSF. For hormone-induced lactation, animals were given estradiol (0.25mg/kg, IM), progesterone (0.75mg/kg, IM), and prednisolone (0.4mg/kg, IM

21. Influência de combinações de diferentes caotrópicos no espectro visível da hemoglobina e na estabilidade de membrana de eritrócitos humanos / Influence of combinations of different chaotropes in the visible spectrum of hemoglobin
CHAPTER II: This study aimed to investigate the influence of combinations of urea, ethanol and hypotonicity on the stability and spectrum of human hemoglobin. Protocols with fixed incubation time of 30 minutes at 37 C were used to analyze the spectra of commercial hemoglobin and hemoglobin of venous blood obtained from 20 healthy volunteers. The visible spec

22. Effect of moxifloxacin administration on pharmacokinetics of tolfenamic acid in rats
Pharmacokinetics of tolfenamic acid as a single drug (4 mg/kg, intramuscularly) and its co-administration with moxifloxacin (5 mg/kg, intramuscularly) in wistar rats were studied. The plasma drug concentration of tolfenamic acid was assayed by LC-MS/MS. Following intramuscular administration of tolfenamic acid as single drug and in combination with moxifloxa

23. Partially aerated attached biomass bed reactor applied to treatment sanitary sewage treatment / Reator com leito de biomassa aderida aerado parcialmente aplicado ao tratamento de esgoto sanitário
This work aimed to evaluate the performance of a full scale up-flow attached biomass bed reactor (159 M POT.3) and with continuous aeration at 7 m above bottom of the reactor to sanitary sewage treatment. The bed of the reactor was constituted for activated granular carbon, anthracite carbon and sand. The work was divided into two stages. In the first stage,

24. Componentes do balanço de água em um Cambissolo cultivado com meloeiro irrigado por gotejamento, com e sem cobertura da superfície / Water balance components in an Inceptsol cropped with muskmelon drip irrigated, with and without covered surface
The knowledge about the soil water balance is essential to soil-water-plant system management. Thus, this research aimed to study the water balance components in an Inceptsol cropped with muskmelon under drip irrigation, with and without surface covering, in the county of Baraúna, Rio Grande do Norte State, Brazil (05º0448 S, 37º3700 W).
