Toward Global Harmonization of Training and Certification of Specialists in Laboratory Animal Veterinary Medicine.

Laboratory animal medicine (LAM) is a corner stone of animal-based research and has been a veterinary specialty for over 60 y. Today 5 Colleges of LAM (American, European, Japanese, Korean, and Indian) that certify specialists (Diplomates) in LAM are members of the International Association of Colleges of LAM (IACLAM). Goals of IACLAM are to support the development of new Colleges of LAM, to harmonize expectations for the knowledge and skills of newly certified LAM Diplomate, and to harmonize the standards (best practices) for training and examination of candidates among the member Colleges.

Justice Is the Missing Link in One Health: Results of a Mixed Methods Study in an Urban City State.

Background: One Health (OH) is an interdisciplinary collaborative approach to human and animal health that aims to break down conventional research and policy 'silos'. OH has been used to develop strategies for zoonotic Emerging Infectious Diseases (EID). However, the ethical case for OH as an alternative to more traditional public health approaches is largely absent from the discourse.

Introducing One Health to the Ethical Debate About Zoonotic Diseases in Southeast Asia.

Pandemic plans recommend phases of response to an emergent infectious disease (EID) outbreak, and are primarily aimed at preventing and mitigating human-to-human transmission. These plans carry presumptive weight and are increasingly being operationalized at the national, regional and international level with the support of the World Health Organization (WHO). The conventional focus of pandemic preparedness for EIDs of zoonotic origin has been on public health and human welfare.

Reproductive performance of mice in disposable and standard individually ventilated cages.

This study assessed the reproductive performance of mice housed in 2 types of individually ventilated caging systems. Breeding pairs from 48 female and 24 male mice of 3 established transgenic mouse breeding colonies were placed in either a standard or disposable ventilated caging system. For 3 breeding cycles, the number of pups born, pup survival rate to weaning, time interval between litters, and pup weights were monitored for each breeding pair.

Operation of an air filtration device results in morbidity and mortality in growing chickens (Gallus gallus domesticus).

Environmental conditions may influence experimental outcomes in laboratory animals. In this study, we measured the effects of a vortex air-filtration device (AFD) on growth rate, morbidity, mortality, behavior, and gross pathology in P2a Leghorn chickens (Gallus gallus domesticus) raised from hatchlings to 6 wk of age. Growth rate was reduced in the group exposed to the operating AFD ('AFD on' group) compared with the 2 control groups ('AFD off' and 'Historical' groups).

Medical records for animals used in research, teaching, and testing: public statement from the American College of Laboratory Animal Medicine.

Medical records are considered to be a key element of a program of adequate veterinary care for animals used in research, teaching, and testing. However, prior to the release of the public statement on medical records by the American College of Laboratory Animal Medicine (ACLAM), the guidance that was available on the form and content of medical records used for the research setting was not consistent and, in some cases, was considered to be too rigid. To address this concern, ACLAM convened an ad hoc Medical Records Committee and charged the Committee with the task of developing a medical record guideline that was based on both professional judgment and performance standards.

Criteria for high-level expression of a fungal laccase gene in transgenic maize.

Expression of industrial enzymes in transgenic plants offers an alternative system to fungal fermentation for large-scale production. Very high levels of expression are required to make the enzymes cost-effective. We tested several parameters to determine the best method for achieving high levels of expression for a fungal laccase gene.

An analysis of avidin, biotin and their interaction at attomole levels by voltammetric and chromatographic techniques.

The electroanalytical determination of avidin in solution, in a carbon paste, and in a transgenic maize extract was performed in acidic medium at a carbon paste electrode (CPE). The oxidative voltammetric signal resulting from the presence of tyrosine and tryptophan in avidin was observed using square-wave voltammetry. The process could be used to determine avidin concentrations up to 3 fM (100 amol in 3 microl drop) in solution, 700 fM (174 fmol in 250 microl solution) in an avidin-modified electrode, and 174 nM in a maize seed extract.

Advantageous features of plant-based systems for the development of HIV vaccines.

Plants have recently become an attractive option for the production of recombinant proteins. Plant-based systems can be used to produce many classes of foreign proteins including candidate vaccine antigens. The selected antigen can be purified from plant material prior to delivery by the preferred route, or alternatively delivered orally in edible plant material that has been processed to give a homogeneous and stable product.

The long-term survival of baboon-to-monkey kidney and liver xenografts.

The present study was undertaken to develop an optimum immunosuppressive regimen in baboon-to-monkey life-supporting kidney xenografts. Baseline therapy for all groups include cyclosporine (CsA) and steroids. We compared adding (1) cyclophosphamide (CyP) at dose of 20 mg/kg/day given on post-operative day (POD) 0, 2, 5 and 7; (2) mycophenolic mofetil (MMF) at a dose of 40 mg/kg/day by daily gavage; or (3) CyP + rapamycin (Rap).

Application of avidin-biotin technology and adsorptive transfer stripping square-wave voltammetry for detection of DNA hybridization and avidin in transgenic avidin maize.

The proteins streptavidin and avidin were electrochemically detected in solution by adsorptive transfer stripping square wave voltammetry (AdTS SWV) at a carbon paste electrode (CPE). AdTS SWV was used to quantify biotinylated oligonucleotides, DNA hybridizations, and avidin in extracts of transgenic avidin maize. The detection limits of denatured and native streptavidin were 6 pM and 120 nM, respectively.

Maize (Zea mays)-derived bovine trypsin: characterization of the first large-scale, commercial protein product from transgenic plants.

Bovine trypsin (EC 3.4.21.

Improvement in human decay accelerating factor transgenic porcine kidney xenograft rejection with intravenous administration of gas914, a polymeric form of alphaGAL.

Background: The present study was undertaken to determine whether intravenous administration of GAS914, a polymeric form of alphaGal, would minimize porcine kidney xenograft rejection in baboons. Human decay accelerating factor renal xenografts were transplanted into 16 baboon recipients.

Methods: Baseline immunosuppression for all groups included cyclosporine A, cyclophosphamide, SDZ-RAD, and methylprednisolone.
