16. STUDY OF THE EFFECTS OF ADJUVANTS ASSOCIATED WITH INSECTICIDES ON THE PHYSICOCHEMICAL PROPERTIES OF THE SPRAY SOLUTION AND CHARACTERIZATION OF DEPOSITS ON WHEAT AND MAIZE LEAVES UNDER SIMULATED RAIN
ABSTRACT The association of adjuvants with phytosanitary products has been tested for several years but is commonly recommended without considering technical and scientific criteria. This study aimed to evaluate the influence of the association of insecticides with different adjuvants on surface tension, contact angle, coverage, hydrogen ionic potential (pH)

17. Moderate or severe LUTS is associated with increased recurrence of non - muscle - invasive urothelial carcinoma of the bladder
ABSTRACT Purpose: Non - muscle - invasive bladder cancer (NMIBC) can recur despite transurethral resection (TURBT) and adjuvant intravesical therapy. Tobacco products excreted in the urine are hypothesized to cause tumor - promoting effects on urothelial cells through direct contact. We determined if moderate or severe lower urinary tract symptoms (LUTS) (d

19. Evaluation of the Toxicity of Silver/Silica and Titanium Dioxide Particles in Mammalian Cells
ABSTRACT The increasing concern over the spread of diseases has lead to a high consumption of antimicrobial additives in the medical and industrial fields. Since these particles can lixiviate from loaded materials, the contact between this additive and mammalian cells can occur during manufacture, use and disposal of the products. Silver on fumed silica (AgN

20. Evaluation of metals in tomato sauces stored in different types of packaging
Abstract There is a growing concern about health and food safety when it comes to processed food. In the present study, it has been hypothesized that tomato sauces contain high amounts of metals possibly leached from packaging. Concentrations of As, Cd, Pb, Cr, Ni, Sn and Sb were determined by ICP-MS in tomato sauces stored in metallic, plastic, cellulosic

21. Risk factors for human Mycobacterium bovis infections in an urban area of Brazil
BACKGROUND The World Health Organization (WHO) has classified human zoonotic tuberculosis (TB) due to Mycobacterium bovis as a neglected issue in the developing world. In a recent cross-sectional study in Brazil, three of 189 TB patients presented with a coinfection of M. bovis and M. tuberculosis and were selected as cases for this study. OBJECTIVE The ai

22. Evaluation of the presence of allergens in children's products available for sale in a big city
Abstract: Children's products are considered safe by the general population and doctors. Labels with terms such as "hypoallergenic" or "dermatologically recommended and tested" denote trust and credibility with the idea that they can be used by any individual. Patients with allergic contact dermatitis may be sensitive to allergens present in any product, inc

24. Natural environmental water sources in endemic regions of northeastern Brazil are potential reservoirs of viable Mycobacterium leprae
BACKGROUND The detection of live Mycobacterium leprae in soil and animals other than humans suggests that the environment plays a role in the transmission of leprosy. OBJECTIVE The objective of this study was to investigate the presence of viable M. leprae in natural water sources used by the local population in five municipalities in the state of Ceará,
