Blood lactate concentration (BLC) is widely used to guide resuscitation in critically ill patients [1]. Muscular microdialysis has previously been used illustrate the importance of the Na/K pump in hyperlactatemia in septic shock patients [2], with BLC reflecting metabolic changes rather than oxygen debt [3]. Microdialysis has now also been applied to intravascular continuous monitoring [4] (Ei...

d before initiating treatments. Cows were blocked by lactation number and assigned randomly to 3 treatments consisting of variations of the Ovsynch protocol. Cows in Cosynch-48 and Ovsynch received injections of GnRH 7 d before and 48 h after a PGF injection. Fixed-time inseminations (TAI) were made at the time of the second GnRH injection (0 h; Cosynch-48) or 24 h (Ovsynch). Those in Cosynch-7...

Bisphenol A (BPA) and phthalates are common environmental contaminants that have been proposed to influence incidence and development of types 1 and 2 diabetes. Thus, effects of BPA and three phthalate metabolites (monoisobutyl phthalate (MiBP), mono-n-butyl phthalate (MnBP), and mono-(2-ethylhexyl) phthalate (MEHP)) were studied in the pancreatic β-cell line INS-1E, after 2-72 h of exposure to...

Prepuberal (P) gilts were induced to ovulate with pregnant mare serum gonadotropin followed 72 h later by human chorionic gonadotropin (hCG). Three P gilts and three mature (M) gilts each were ovariectomized on d 10, 14, 18, 22 and 26 (d 0 = day of hCG for P gilts and onset of estrus for M gilts). Gilts ovariectomized on d 14, 18, 22 and 26 were hysterectomized on d 6 to ensure maintenance of t...

The pharmacokinetic characteristics of cefonicid, a highly protein-bound expanded-spectrum cephalosporin, were examined in six noninfected, clinically stable patients undergoing continuous ambulatory peritoneal dialysis. After a 1.0-g intravenous dose of cefonicid, the mean concentrations in serum were 105 +/- 25 and 35.6 +/- 14.4 micrograms/ml at 3 and 72 h, respectively. Despite a prolonged h...

The reaction of three-dimensional cultures of pulp-derived cells in a dentin barrier test was recorded after exposure to All-Bond 2, Prime & Bond NT, Syntac SC, Syntac Classic, and Prompt L-Pop. The materials were applied on bovine dentin disks in a perfusion chamber, and the experiments were performed with (0.3 ml/h, 2 ml/h) and without perfusion of the pulpal part of the chamber. The cell rea...

Nowadays, plant allelopathy, as a new type of biological algal and/or bacterial inhibition technology, has attracted extensive attention. Eight substances were isolated and identified from Jussiaea stipulacea Ohwi, five concentration gradients, well control (0, 1.25, 5, 10, 20, 50 mg/L) set, with three parallels in each group, then sampled detected at 24, 48, 72, 96 h. When the was mg/L, rate A...

This study was designed to compare the effect of fluid percussion brain injury (FPI) on the hypotensive cerebrovascular response in newborn and juvenile pigs as a function of time postinsult and to determine the role of endothelin-1 (ET-1) in any age-dependent differences in hypotensive cerebrovascular regulation after injury. Ten minutes of hypotension (10-15 ml blood/kg) decreased mean arteri...

The golden mussel Limnoperna fortunei (Dunker 1857) is one of the most distributed Nuisance Invasive Species (NIS) in South America, and a threat of great concern for the industry of the area. In this study, we carried out toxicity tests made with a Neem's oil solution with L. fortunei larvae and benthonic adults (7, 13 and 19 ± 1 mm). Tests with non-target species (Daphnia magna, Lactuca sativ...

The green seaweed Enteromorpha prolifera was used as a feedstock for the production of enzymatic hydrolysate using cellulase. The selection of the conditions for enzymatic hydrolysis of the biomass was carried out for different enzyme doses and incubation periods. The obtained extract was examined in terms of its multielemental composition, content of polyphenols and antibacterial properties (t...
