HtrA2/Omi, a Sheep in Wolf's Clothing

Mammalian mitochondrial HtrA2/Omi was originally described as an apoptosis inducer, but rather than having extra cells, mice with mutant HtrA2/Omi suffer from a neurodegenerative disease due to progressive mitochondrial damage. This suggests that instead of promoting cell death by antagonizing inhibitor of apoptosis (IAP) proteins, the primary function of HtrA2/Omi is to handle misfolded protei...

Attrition Bias in Panel Data: A Sheep in Wolf's Clothing? A Case Study Based on the Mabel Survey.

This paper investigates the nature and consequences of sample attrition in a unique longitudinal survey of medical doctors. We describe the patterns of non-response and examine if attrition affects the econometric analysis of medical labour market outcomes using the estimation of physician earnings equations as a case study. We compare the econometric gestimates obtained from a number of differ...

Sheep in wolf's clothing: host nestling vocalizations resemble their cowbird competitor's.

Nestlings of many avian brood parasites are virtuosos at mimicking host nestling vocalizations, which, like egg mimicry, presumably ensures acceptance by host parents. Having been accepted, parasitic nestlings then often exaggerate the aspects of the host's display to increase parental care. Host nestlings may, in turn, exaggerate their vocalizations to keep up with the parasite, though this po...

Periampullary carcinoid of the ampulla of Vater presenting as an intraductal papillary mucinous tumour of the pancreas: a sheep in wolf's clothing.

estimated incidence at all anatomic sites of 1 in 12 000. Although 67% of these lesions are found within the gastrointestinal tract, fewer than 1% are located at or near the ampulla of Vater. These periampullary tumours have characteristics that set them apart from carcinoids at other sites, including strong immunohistochemical positivity for somatostatin and presence of psammoma bodies. Althou...
