25. SPATIO-TEMPORAL DYNAMICS OF TOXIC CYANOBACTERIA IN AN ARTIFICIAL LAKE IN THE BRAZILIAN SEMI-ARID REGION
RESUMO A intensificação do processo de eutrofização nas águas superficiais leva a um aumento da intensidade e frequência de florações de cianobactérias comprometendo a disponibilidade hídrica para o uso consuntivo. Deste modo, objetivou-se estudar a dinâmica espaço-temporal das cianobactérias e a identificação dos nutrientes de maior peso ness

26. Dynamics of nuclear and cytoplasm maturation of bovine oocytes cultivated in vitro in medium supplemented with fulerol
RESUMO O objetivo deste estudo foi avaliar, in vitro, a dinâmica da maturação nuclear e citoplasmática de oócitos bovinos em meio MIV tradicional (TC) e suplementado com fulerol (MF50), durante 36 horas. Na maturação nuclear do TC (n=300) e do MF50 (n=270) a cada seis horas, corados com Hoechst 33342, e na citoplasmática, avaliou-se a distribuição

27. Temperature Dependent Emission Properties of ReI Tricarbonyl Complexes with Dipyrido-Quinoxaline and Phenazine Ligands
In this work, the emission properties of fac-[Re(CO)3(NN)(py)]+, NN = 1,10-phenanthroline (phen), dipyrido[3,2-f:2’,3’-h]quinoxaline (dpq) and dipyrido[3,2-a:2’3’-c]phenazine (dppz); py = pyridine were investigated in different temperatures, ranging from 80 to 300 K, and in different solvent mixtures and in polymethyl methacrylate. The changes observ

28. Surgical Outcome of Modified Karydakis Flap and Modified Limberg Flab in the Management of Sacroccygeal Pilonidal Disease: A Comparative Study
Abstract Introduction Sacrococcygeal pilonidal disease (SPD) is a chronic suppurative condition of the sacrococcygeal region causing chronic sinus tract or cyst. It is an acquired complex disease more common in young adult males, causing considerable morbidity and long periods of interruption in work or education. From simple conservative techniques to comp

30. The circadian timing of noise exposure influences noise-induced inflammatory responses in the mouse cochlea
Abstract Introduction: Noise-induced hearing loss is one of the most common forms of sensorineural hearing loss. Nevertheless, the mechanisms of noise-induced hearing loss are still not fully understood. Objective: To investigate the dynamics of inflammatory responses in the mammalian cochlea following noise trauma at two different times, once during the l

31. Perfil cientométrico da Quimiometria no Brasil
The interest of researchers in understanding the stage of development of specific areas of knowledge is a way to understand their scientific maturity and their capacity for consolidation. This “popularization” of the knowledge of researchers working in a specific area of knowledge also allows a greater ability to recognize where science is produced and w

34. TRAILER HEAT ZONES AND THEIR RELATION TO HEAT STRESS IN PIG TRANSPORT
ABSTRACT This study evaluates the dynamics of heat zones in the load and its relationship with the stress of pigs during transport. Four journeys of 170 km were monitored, recording the physiological variables of 192 animals (48 per journey), namely rectal temperature (RT), body temperature (BT), respiratory rate (RR), blood lactate concentrations and saliva

35. Record of Conotelus luteicornis Erichson (Coleoptera: Nitidulidae) in passion fruit vine in Acre state, Brazil
ABSTRACT The first record of Conotelus luteicornis Erichson (Coleoptera: Nitidulidae) was made in a commercial passion fruit vine planting in the municipality of Senador Guiomard, Acre state, Brazil. The insects were found inside the flowers where larvae and adults feed, causing early abortion and, consequently, losses in production. Therefore, the first rec

36. Linear and Nonlinear Heart Rate Variability Analysis in Gonadal Dysgenesis (Swyer Syndrome): A Case Report
Abstract Swyer syndrome is one of the disorders of sexual differentiation. Previous studies have demonstrated increased sympathetic activity with heart rate variability (HRV) analysis with decreasing estradiol levels. One patient presented a pure 46, XY gonadal dysgenesis with female phenotype. Cardiac autonomic modulation was assessed through HRV analysis w
