2. Effect of glycerol, n, n-dimethylformamide and n-methyl-2-pyrrolidone on rabbit sperm stored at 4 °C and 16 °C
Abstract Artificial insemination with cooled semen is the most common practice in rabbit farms and any improvement on it helps to increase the efficiency and productivity of rabbit meat farms. Therefore, the aim of this study was to assess whether different cryoprotectant agents (CPA) as glycerol, N, N-Dimethylformamide (DMF) and N-Methyl-2-Pyrrolidone (NMP)

3. Development of a natural molluscicide prototype kit (MoluSchall) for the control of schistosomiasis mansoni transmission
Abstract INTRODUCTION In Brazil, Biomphalaria glabrata, B. tenagophila, and B. straminea are intermediate hosts of Schistosoma mansoni, the etiological agent of schistosomiasis mansoni. Molluscicide use is recommended by the WHO for controlling the transmission of this parasite. Euphorbia milii latex has shown promising results as an alternative molluscici

5. EVALUATION OF COCAINE SAMPLES SEIZED IN THE STREETS OF THE STATE OF RIO DE JANEIRO, BRAZIL
Fifty-two samples of street cocaine seized in the state of Rio de Janeiro, from May 2016 to April 2017, were evaluated according to their purity, presence of inorganic and sugar diluents and concentration of pharmacologically active adulterants. Cocaine contents, as well as the adulterants caffeine, lidocaine and phenacetin, were evaluated by gas chromatogra

6. Influence of the Fraction of Comonomers and Diluents on the Preparation of Polymeric Microspheres Based on Poly (Methacrylic acid-co-divinylbenzene) Obtained by Precipitation Polymerization
Abstract Preparation and characterization of polymeric microspheres based on poly(methacrylic acid-co-divinylbenzene) (P(MAA-co-DVB)) by precipitation polymerization are reported. The influence of the change in comonomer composition, crosslinking degree, ratio of total monomers/diluents by weight/volume (g/100 mL) and the volume ratio of diluents were studie

7. EFFECTS OF GRADUAL FEED DILUTION WITH INERT OR LESS NUTRITIVE MATERIALS ON GROWTH PERFORMANCE, FEED COST AND MEAT ORGANOLEPTIC PROPERTIES OF BROILER CHICKEN
ABSTRACT The objective of the present study was to determine the effects of the gradual dilution of broiler finisher diets with inert or less nutritive materials on growth performance, feed cost, and meat organoleptic properties. Broiler chicks (n=147) were allocated into 49 pens and fed a mash broiler finisher diet (control) or the control diet diluted eith

8. A study of parameters affecting the solvent extraction of lactic acid from fermentation broth
Lactic acid has recently been drawing much interest as a raw material for biodegradable polymer. One of the promising technologies for recovery of lactic acid from fermentation broth is reactive liquid - liquid extraction. Equilibrium studies on the reactive extraction of lactic acid with trioctylamine (TOA) in various organic phases and its re-extraction in

9. Assessing the growth and recovery of Salmonella Enteritidis SE86 after sodium dichloroisocyanurate exposure
The objective of the present study was to assess the growth and the recovery of Salmonella (S.) Enteritidis SE86 in different diluents, culture media and using different plating methods after the exposure to 200 mg/kg sodium dichloroisocyanurate (NaDCC). Before and after NaDCC exposure, SE86 was cultured at 30 °C and 7 °C in the following diluents: Peptone

10. Efeitos do trimetilaminoetano (TES) e ringer lactato em sêmen de macacos-aranha mantidos em cativeiro ( Ateles paniscus e A. marginatus)
The performances of the diluents TES and CEBRAN II were compared as cryopreservatives of semen from non human primates of the genus Ateles. The experiment was carried out using one Ateles marginatus and two Ateles paniscus specimens, males and adults, maintained in the same captivity conditions at the National Center of Primates (CENP-SVS/MS). The animals we

12. Simvastatin assay and dissolution studies by feasible RP-HPLC in tablets
Commonly used HPLC acetonitrile solvent has been through a worldwide shortage with a cost increase in 2008 and 2009. In order to get around this situation, a method by RP-HPLC employing methanol and aqueous acid mobile phase was developed and validated to evaluate simvastatin. The quality control assay and dissolution studies of this lipid-lowering drug were
