Comparative Studies for Cryopreservation of Shoot Tips by Droplet-Vitrification.

The objective of this work was to assess the suitability of the Droplet-vitrification protocol previously developed with shoot tips for the cryopreservation of six species. Shoot tips were precultured for 1 day on a medium with 0.3 M sucrose in the dark, loaded in a solution with 1.

seroprevalence in sheep herd from Paraguay: First evidence of bacterial circulation in the country.

is the agent of Q fever, a disease that poses risks to public health and damages livestock. We discovered the circulation of for the first time in Paraguay, based on the seropositivity of a flock of >300 sheep. The animals were tested by IFA for anti- antibodies and by SAM for anti- spp.

Increased Plasticity in Invasive Populations of a Globally Invasive Cactus.

Biological invasions pose global threats to biodiversity and ecosystem functions. Invasive species often display a high degree of phenotypic plasticity, enabling them to adapt to new environments. This study examines plasticity to water stress in native and invasive populations, a prevalent invader in arid and semi-arid ecosystems.

[Quality of life of patients who underwent a bile duct reconstruction].

Background: Bile duct reconstruction (BDR) secondary to bile duct injury during cholecystectomy (BDIC) is a complex surgery, and an important issue is the quality of life (QL) after the procedure.

Aim: To compare the QL of a cohort of patients who underwent BDR due to BDIC with a cohort of patients who underwent a cholecystectomy without incidents.

Material And Methods: The cohort was composed of 32 patients aged 47 ± 18 years (78% women) who underwent BDR due to BDIC.
