    Feather holes have traditionally been suggested to be feeding traces of chewing lice (mallophagans). There is controversy whether mallophagans are the real source of feather holes. We studied mallophagan infestations and holes in tail feathers of 528 ...

    Iceland is free of the major infectious diseases of horses. However, in 2010 an epidemic of respiratory disease of unknown cause spread through the country’s native horse population of 77,000. Microbiological investigations ruled out known viral agents ...

    Apicomplexans comprise a group of unicellular, often highly pathogenic, obligate parasites exploiting either one or two hosts to complete a full reproductive cycle. For decades, various scallop populations have suffered cyclical mass mortality events, ...

    Populations of rock ptarmigan (Lagopus muta) in Iceland fluctuate in multiannual cycles with peak numbers c. every 10 years. We studied the ptarmigan-parasite community and how parasites relate to ptarmigan age, body condition, and population density. ...
  • Foxler, Daniel E.; Bridge, Katherine S.; James, Victoria; Webb, Thomas M.; Mee, Maureen; Wong, Sybil C. K.; Feng, Yunfeng; Constantin-Teodosiu, Dumitru; Petursdottir, Thorgunnur Eyfjord; Bjornsson, Johannes; Ingvarsson, Sigurður; Ratcliffe, Peter J.; Longmore, Gregory D.; Sharp, Tyson V. (Springer Nature, 2012-01-29)
    There are three prolyl hydroxylases (PHD1, 2 and 3) that regulate the hypoxia-inducible factors (HIFs), the master transcriptional regulators that respond to changes in intracellular O(2) tension. In high O(2) tension (normoxia) the PHDs hydroxylate ...

    The miR-451 was found to be frequently down-regulated in tumors, indicating that miR-451 could play an important role in carcinogenesis. This study uncovered the mechanism by which the miR-451 functions as a tumor suppressor. The target genes of miR-451 ...

    Winter ulcer disease, caused by Moritella viscosa, is a significant problem in cold water salmonid farming, although the bacterium can infect and cause disease in a number of other fish species, such as lumpfish (Cyclopterus lumpus). Lumpfish are used ...

    Neonatal foals respond poorly to conventional vaccines. These vaccines typically target T-helper (Th) cell dependent B-cell activation. However, Th2-cell immunity is impaired in foals during the first three months of life. In contrast, neonatal basophils ...
