The objective of this study was evaluate the maintenance of the corneal endothelium of horses in cold EUSOL-C® preservation medium over different periods (seven and 14 days) using scanning electron microscopy. A total of 20 pairs of eyes from horses were analysed. The corneas were divided into four groups of 10 corneas each (G1, G2, G3 and G4): G1 - the samples were kept in the preservation medium for seven days; G3 - the samples were kept in the preservation medium for for 14 days; G2 and G4 were formed by the control corneal buttons of G1 and G3, respectively. The average cell loss observed in G1 was 7.62%, in G2 it was 7.04%, in G3 9.12% and in G4 7.16%. No statistically significant differences were observed between the four groups. It was concluded that the Eusol-C® hypothermic preservation medium provided satisfactory preservation of the corneal endothelium in equine species for up to 14 days.

ABSTRACT Liquid-based microbiology (LBM) devices incorporating flocked swabs and preservation medium ease transport of specimens and improve specimen yield compared to traditional fiber wound swabs; however, the performance of LBM collection devices has not been evaluated in many molecular assays. It is unclear how the differences in matrix and specimen loading with an LBM device will affect test performance compared to traditional collection devices. The purpose of this study was to evaluate the performance of specimens collected in FecalSwab transport medium (Copan Diagnostics, Murrieta, CA) compared to unpreserved stool using the Cepheid Xpert C. difficile assay (Cepheid, Sunnyvale, CA). Results equivalent to unpreserved stool samples were obtained when 400 μl of FecalSwab-preserved stool was employed in the Xpert assay. The positive and negative percent agreement of specimens inoculated with FecalSwab medium ( n = 281) was 97.0% (95% confidence interval [CI], 90.9 to 96.4%) and 99.4% (95% CI, 96.4 to 99.9%), respectively, compared to reference results obtained using unpreserved stool. Throughout this study, only four discrepant results occurred when comparing preserved specimens to unpreserved stool specimens in the Xpert C. difficile PCR assay. Post discrepant analysis, using the BD MAX Cdiff assay, the specificity and sensitivity both increased to 100%. The high positive and negative percent agreements observed in this study suggest that stool preserved in FecalSwab media yields equivalent results to using unpreserved stool when tested on the Xpert C. difficile assay, allowing laboratories to adopt this liquid-based microbiology collection device.

Abstract Viability of rabbit platelets stored for 1 to 6 days in different media at 4 C. was studied using the Cr51-platelet survival technic. Platelets stored for 24 hours in Triton-saline or DAS-gelatin had practically no viability. When platelets were stored for 24 hours in diluted plasma, significant degrees of viability were found, but this decreased rapidly in the successive 48 hours. The viability of platelets stored in diluted plasma containing inosine, adenine, glucose and phosphate buffer was maintained at significant levels over a six day period. The data presented here suggest that viability and, consequently, the hemostatic properties of platelets stored at 4 C. can be maintained over relatively long periods of time provided that loss of the ATP reserve of the cells can be prevented.

The objective of this research was  to obtain suitable concentration of sucrose and agar in the sweet potato (Ipomea batatas (L) Lam) in vitro preservation medium, in order to make plant grow slowly and healthy. Experiment was done in Molecular Biologi Laboratory of PAU IPB. The experiment was arranged in factorial complete random design, using sweet potato var. Sukuh in order to know the effect of sucrose (40,50,60,70 and 80 g l-1) and agar (7 and 8 g l-1) which were added 1 g l-1 hyponex fertilizer 20-20-20. The experiment was replicated four times. Data were analyzed parametrically and non-parametrically. The result of these experiments showed the suitable conservation media was 1 g l-1 hyponex 20-20-20 + 60 g l-1sucrose + 7 g l-1 agar. Threfore, the media composition MS could produce high green inter nodes number, high root number and more than two green leaf number. This experiment also showed that MS media could be replaced by a cheaper and easily found conservation medium.
