| A new matrix resin was recently introduced for composite materials, based on acrylic resin chemistry allowing standard room temperature infusion techniques to be used to produce recyclable thermoplastic composites. This is a significant advance, particularly for more environmentally-friendly production of large marine structures such as boats. However, for such applications it is essential to demonstrate that composites produced with these resins resist sea water exposure in service. This paper presents results from a wet aging study of unreinforced acrylic and glass and carbon fibre reinforced acrylic composites. It is shown that the acrylic matrix resin is very stable in seawater, showing lower property losses after seawater aging than those of a... |

| This study was conducted to investigate the effects of the replacement of drinking water by herb infusions on the performance, relative weight of internal organs, hematocrit and immune response to Newcastle disease virus of broiler chickens. A total of 540 male broiler chicks (Ross 308) were divided into five groups, corresponding to four different treatments and one control group. Treatments were replicated eight times, and the control group four times. Experimental treatments included infusions (5 grams per liter) of cinnamon, thyme and turmeric in equal ratios in replacement of drinking water. Experimental period lasted 21 days and all chicks were fed with a corn-soybean based diet. Results showed that all herbs infusions caused significant (p<0.05)... |

| Stress hormones can alter metabolic functions in adipose tissue and liver, as well as the sensitivity of rat white adipocytes and rat atrial responses to ß-adrenergic agonists. In this study, we examined the effects of three daily footshock stress sessions on the plasma corticosterone, glucose, glycerol and triacylglycerol levels of fed, conscious male rats, and on the plasma glucose, glycerol and triacylglycerol levels of the same rats following iv infusions of ß-adrenergic agonists (isoproterenol: 0.4 nmol kg-1 min-1, noradrenaline: 5.0 µg kg-1 day-1, and BRL 37344 ([±]-[4-(2-[(2-[3-chlorophenyl]-2-hydroxyethyl)amino]propyl)phenoxy]acetic acid), a selective ß3-adrenoceptor agonist: 0.4 nmol kg-1 min-1). Plasma corticosterone levels increased... |

| ABSTRACT: The aqueous extract of Aristolochia triangularis leaves showed activity against Artemia salina larvae, with an LD50 of 370.6 µg/mL. In experiments with Allium cepa seeds, the extract caused a 51.26% reduction in the germination index, inhibited mean root growth, and was cytotoxic at concentrations of 668 and 2,000 µg/mL. Its antioxidant activity was additionally assessed in this research and the ferric reducing antioxidant power value was found to be 391.2 µM/g. Such health-beneficial property can be attributed partly to the total phenolic content, spectrophotometrically determined as 52.67 mg/g. The occurrence of cytotoxicity suggested caution when consuming teas from A. triangularis leaves for medicinal purposes, and equally reveals the need... |
