Article Synopsis
  • The food enzyme carboxypeptidase C is produced using a genetically modified strain by DSM Food Specialties, and its genetic modifications present no safety issues.
  • This enzyme is intended for use in nine food manufacturing processes, with estimated dietary exposure levels for Europeans being up to 2.053 mg TOS/kg body weight per day.
  • Toxicity studies show it has no significant adverse effects, but there is a potential, albeit low, risk of allergic reactions in individuals with wheat allergies.

Directive 2010/63/EU introduced requirements for the classification of the severity of procedures to be applied during the project authorisation process to use animals in scientific procedures and also to report actual severity experienced by each animal used in such procedures. These requirements offer opportunities during the design, conduct and reporting of procedures to consider the adverse effects of procedures and how these can be reduced to minimize the welfare consequences for the animals. Better recording and reporting of adverse effects should also help in highlighting priorities for refinement of future similar procedures and benchmarking good practice.

Brain trimming through defined neuroanatomical landmarks is recommended to obtain consistent sections in rat toxicity studies. In this article, we describe a matrix-guided trimming protocol that uses channels to reproduce coronal levels of anatomical landmarks. Both setup phase and validation study were performed on Han Wistar male rats (Crl:WI(Han)), 10-week-old, with bodyweight of 298 ± 29 (SD) g, using a matrix (ASI-Instruments(®), Houston, TX) fitted for brains of rats with 200 to 400 g bodyweight.

Aim: in the present study, we report the circadian profiles of a wide panel of hormones measured in rats and common marmosets (Callithrix jacchus), under physiological conditions, paying special attention to minimising the stress imposed on the animals.

Materials And Methods: blood collections were performed over a 24-hour period for the analysis of stress and pituitary hormones, metabolic markers and cytokines from male cannulated rats connected to a fully automatic system, and healthy marmosets in which gender differences were also evaluated.

Results: in rats, a significant time effect was observed for corticosterone, prolactin (PRL), thyroid stimulating hormone (TSH), growth hormone, follicle-stimulating hormone, brain-derived neurotrophic factor, total ghrelin, insulin, leptin, insulin-like growth factor-1, adiponectin and interleukin-10.

Objective: The main objective of the study was to determine the effects of three different infusion rates of fentanyl and remifentanil on the minimum alveolar concentration (MAC) of isoflurane in the rat. A secondary objective was to assess the cardiovascular and respiratory effects of the two opioid drugs.

Animal Population: Thirty-seven male Wistar rats were randomly allocated to one of six treatment groups.

This study was carried out to determine whether cyanoacrylate gel was suitable for use as a substitute for dental cement during brain implant surgery of rats. Intracerebroventricular (ICV) cannulations were performed in 24 rats by two surgeons, one with 3 years' experience in this type of surgery, and one novice, with only basic training performed on cadavers. Each surgeon prepared six randomly allocated animals using dental cement to secure the cannula and six with cyanoacrylate gel.
