1. Association of L-arginine with heparin on the sperm capacitation improves in vitro embryo production in bovine
Abstract We aimed to evaluate the effects of L-arginine (L-arg) in the quality of in vitro heparin-induced capacitation of cryopreserved bovine spermatozoa and its effects on IVP. The experimental groups were: Control 0 hour without pre-capacitation, and groups of sperm capacitated for 30 min in the absence of COC with heparin (Control 30 min), with 1 mM L-a

4. Estudos das propriedades ópticas dos complexos európio tetraciclinas e suas aplicações na detecção de lipoproteínas / Studies of optical properties of complexes europium tetracycline and its applications in detection of lipoproteins
This work presents the optical properties of europium complexes - Tetracyclines (EuTcs) in the presence of LDL and oxidized LDL with potential applications in clinical analysis. Four elements were chosen from the Tetracyclines family: Tetracycline (Tc), Chlortetracycline (CTc), Metatetraciclina (MTc) and Oxytetracycline (OTc) to be part of complexes with eur

5. Polarographic study and electrode kinetics of [Zn(II) - antibiotics - cephaloglycin] system vis a vis kinetics of electrode reactions
Electrode kinetics and complex formation of Zn(II) using doxycycline, chlortetracycline, oxytetracycline, tetracycline, minocycline, amoxicillin, chloramphenicol and cephaloglycin were reported at pH = 7.30 ± 0.01 in = 1.0 molL-1 NaClO4 used as supporting electrolyte at 25.0°C. Kinetic parameters viz. transfer coefficient (α), degree of irreversibility (�

6. Programas preventivos com antibióticos para suínos em fase de creche e efeitos no desempenho, características de carcaça e índices sanitários
The use of "pulses" or "shocks" with antibiotics has been recommended and widely used throughout the production chain from pigs in Brazil. Accordingly, the objective of this study was to identify the best preventive program with antibiotics waived at the stage of nursery, which has effects consistent and lasting until the slaughter, reducing potential for lo

7. Electrochemical study and dependence of 'transition state' in Co(II) and Ni(II) complexes with some antibiotics and cephalothin
Electrode kinetics and study of 'transition state' with applied potential in case of [M - antibiotics - cephalothin] system were reported at pH = 7.30 ± 0.01 at suitable supporting electrolyte at 25.0ºC. The M = Co or Ni and antibiotics were doxycycline, chlortetracycline, oxytetracycline, tetracycline, minocycline, amoxicillin and chloramphenicol used as

8. Three new complexes of platinum(II) with doxycycline, oxytetracycline and chlortetracycline and their antimicrobial activity
Este artigo descreve a síntese e a caracterização de três novos complexos de platina(II) com a oxitetraciclina, doxiciclina e clortetraciclina por análise elementar, espectroscopias IV e RMN de 195Pt. As interações da doxiciclina com íons PtII em função do pH foram estudadas por RMN de ¹H. Todas as tetraciclinas investigadas formam complexos 1:1 c

10. Complexação da tetraciclina, da oxitetraciclina e da clortetraciclina com o catião cobre (II). Estudo potenciométrico
Stability constants of complexes formed by copper (II) with three different tetracyclines (tetracycline, oxytetracycline and chlortetracycline) have been determined potentiometrically with an automatic system in aqueous medium at 25,0 ± 0,2 ºC and I = 0,1 mol L-1 NaNO3. The protonation constants of the three tetracyclines were also determined under the sam

11. Some characteristics and antibiotic resistance of anaerobic bacteria from the ceca and colons of pigs fed chlortetracycline-containing and unmedicated diets.
Morphology and end product patterns were used to group 112 bacterial isolates from the ceca and colons of pigs fed unmedicated and chlortetracycline-containing diets. Most of the isolates (68%) were resistant to chlortetracycline (greater than 4 micrograms/ml). Chlortetracycline resistance was associated with all groups of anaerobic and facultative bacteria.

12. Changes in the prevalence of resistant Escherichia coli in cattle receiving subcutaneously injectable oxytetracycline in addition to in-feed chlortetracycline compared with cattle receiving only in-feed chlortetracycline
Information about the prevalence of antibiotic resistance in commensal enteric bacteria is of interest because these bacteria are potential indicators of selection pressure on enteric bacteria and represent a reservoir of resistance genes in potentially pathogenic bacteria. This study reports changes in the prevalence of resistance to antibiotics in commensa
