Definitive Glasgow acute pain scale for cats: validation and intervention level
In order to improve the performance of the tool, a simple three-point facial scale, which in preliminary testing had performed very well in classifying cats in pain, was developed ( Holden and others 2014 ) with the intention of embedding it within the behaviour-based cat tool, an approach adopted previously in paediatric medicine (CRIES ( Krechel and others 1995 ); Premature Infant Pain Profile ( Stevens and others 1996 )). In summary, the CMPS-Feline with its embedded facial image component has been shown to be a valid scale for the measurement of acute pain in cats in general veterinary practice with a recommended intervention level of 5 and above (out of a total possible score of 20).

PRELIMINARY RESULTS FROM GLASGOW INTERNATIONAL RADIOCARBON INTERCOMPARISON
GIRI (Glasgow International Radiocarbon Intercomparison) was designed to meet a number of objectives, including to provide an independent assessment of the analytical quality of the laboratory/measurement and an opportunity for a laboratory to participate and improve (if needed). The principles in the design of GIRI were to provide the following: (a) a series of unrelated individual samples, spanning the dating age range, (b) linked samples to earlier intercomparisons to allow traceability, (c) known age samples, to allow independent accuracy checks, (d) a small number of duplicates, to allow independent estimation of laboratory uncertainty, and (e) two categories of samples—bulk and individual—to support laboratory investigation of variability. All of the GIRI samples are natural (wood, peat, and grain), some are known age, and overall their age spans approx. >40,000 years BP to modern. The complete list of sample materials includes humic acid, whalebone, grain, single ring dendro-dated samples, dendro-dated wood samples spanning a number of rings (e.g., 10 rings), background and near background samples of bone and wood. We present an overview of the results received and preliminary consensus values for the samples supporting a more in-depth evaluation of laboratory performance and variability.

Violent ends : a novel in seventeen points of view
Relates how one boy--who had friends, enjoyed reading, playing saxophone in the band, and had never been in trouble before--became a monster capable of entering his high school with a loaded gun and firing on his classmates, as told from the viewpoints of several victims. Each perspective is written by a different writer of young adult fiction.

Helminth-host-environment interactions: Looking down from the tip of the iceberg
In 1978, the theory behind helminth parasites having the potential to regulate the abundance of their host populations was formalized based on the understanding that those helminth macroparasites that reduce survival or fecundity of the infected host population would be among the forces limiting unregulated host population growth. Now, 45 years later, a phenomenal breadth of factors that directly or indirectly affect the host–helminth interaction has emerged. Based largely on publications from the past 5 years, this review explores the host–helminth interaction from three lenses: the perspective of the helminth, the host, and the environment. What biotic and abiotic as well as social and intrinsic host factors affect helminths? What are the negative, and positive, implications for host populations and communities? What are the larger-scale implications of the host–helminth dynamic on the environment, and what evidence do we have that human-induced environmental change will modify this dynamic? The overwhelming message is that context is everything. Our understanding of second-, third-, and fourth-level interactions is extremely limited, and we are far from drawing generalizations about the myriad of microbe-helminth-host interactions.Yet the intricate, co-evolved balance and complexity of these interactions may provide a level of resilience in the face of global environmental change. Hopefully, this albeit limited compilation of recent research will spark new interdisciplinary studies, and application of the One Health approach to all helminth systems will generate new and testable conceptual frameworks that encompass our understanding of the host–helminth–environment triad.

Association between polymorphisms in the Clock gene, obesity and the metabolic syndrome in man
Objective: Accumulating evidence raises the hypothesis that dysregulation of intrinsic clock mechanisms are involved in the development of the metabolic syndrome, type 2 diabetes mellitus and cardiovascular disease. The aim of the present study was to investigate the relationship between three known common polymorphisms in the Clock gene and features of the metabolic syndrome in man. Methods: Genotype and haplotype analysis was carried out in a cohort of 537 individuals from 89 families characterized for inflammatory, atherothrombotic and metabolic risk associated with insulin resistance. Results: Heritability of the metabolic syndrome, defined according to International Diabetes Federation criteria, was 0.40. Haplotype analysis indicated three common haplotypes: CAT, TGT and CGC (rs4864548-rs3736544-rs1801260) with frequencies of 31, 33 and 28%, respectively. The CGC haplotype was less prevalent in subjects with the metabolic syndrome (P=0.0015) and was associated with lower waist circumference (P=0.007), lower hip circumference (P=0.023), lower body mass index (P=0.043) and lower leptin levels (P=0.028). The CAT haplotype was significantly associated with the presence of the metabolic syndrome (P=0.020). Conclusions: These findings suggest that the Clock gene CGC haplotype may be protective for the development of obesity and support the hypothesis that genetic variation in the Clock gene may play a role in the development of the metabolic syndrome, type 2 diabetes and cardiovascular disease.

Learning from the Wood Samples in ICS, TIRI, FIRI, VIRI, and SIRI
Each of the laboratory intercomparisons (from ICS onwards) has included wood samples, many of them dendrochronologically dated. In the early years, as a result of the majority of laboratories being radiometric, these samples were typically blocks of 20–40 rings, but more recently (SIRI), they have been single ring samples. The sample ages have spanned background through to modern. In some intercomparisons, we have examined different wood pretreatment effects, in others the focus has been on background samples. In this paper, we illustrate what we have learned from these extensive intercomparisons involving wood samples and how the results contribute to the global IntCal effort.

Acute Phase Proteins in Bovine Milk in an Experimental Model of Staphylococcus aureus Subclinical Mastitis
The objectives were to establish the origin of 2 acute phase proteins in milk during subclinical bovine mastitis and to characterize the relationship between those proteins in milk and blood. Haptoglobin (Hp) and mammary-associated serum amyloid A (M-SAA3) appear in milk during mastitis, whereas Hp and serum amyloid A increase in serum during mastitis. The concentrations of these proteins were determined in an experimental model using a field strain of Staphylococcus aureus to induce subclinical mastitis in dairy cows. The expression of mRNA coding for these proteins was assessed and the presence of M-SAA3 in mammary tissues was determined using immunocytochemistry. Increases of M-SAA3 and Hp in milk occurred within 12h of Staphylococcus aureus infusion, with peak concentrations occurring 3 d after infusion of the bacteria. The increase of acute phase proteins in milk (15h) preceded the increase in serum concentrations of both proteins (24h). Expression of mRNA for M-SAA3 and Hp increased in both mammary and hepatic tissues 48h after infusion of the mammary glands. In mammary tissue, the increase of M-SAA3 mRNA was greater than the increase in Hp mRNA expression, whereas in hepatic tissue, the increase in M-SAA3 mRNA was less than that for Hp mRNA. Immunocytochemistry demonstrated that M-SAA3 protein was present within secretory epithelial cells at significantly higher levels in infected mammary glands than in control tissues. These proteins, which have host defense and antibacterial activities, may play a significant role in the early response to invasion of mammary tissues by pathogenic bacteria.
