Studies of the flocking behaviour of Sanderlings [PDF]
, 1990 The behaviour of sanderlings, Calidris alba, was studied at Teesmouth, N. E. England. Flock sizes and within-flock spacing were related to factors such as substrate type, season, and prey distribution. Sightings of individually-identifiable colour-ringed

Collective escape in bird flocks [PDF]
, 2023 Flocks of birds exhibit mesmerizing aerial displays when under predation by raptors, but little is known about the variation of these displays, how they relate to each other, and how they depend on the actions of the predator.

Rubin H. Flocks and Colloidal Gold Treatments for Prostate Cancer
The Scientific World Journal, 2011 In the early 1950s, Rubin H. Flocks of the University of Iowa began to treat prostate cancer patients with colloidal gold (Au198) therapy, evolving his technique over nearly 25 years in 1515 patients.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Seroprevalence survey for Salmonella Abortusovis infection in Swiss sheep flocks
, 2010 Between 1976 and 2003, no infections with Salmonella Abortusovis had been officially recorded in Switzerland. Since then, however, several sheep flocks were infected and suffered massive fetal losses suggesting a re-emergence of the disease.

Is the species flock concept operational? The Antarctic shelf case. [PDF]
PLoS ONE, 2013 There has been a significant body of literature on species flock definition but not so much about practical means to appraise them. We here apply the five criteria of Eastman and McCune for detecting species flocks in four taxonomic components of the ...

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Animal, 2019 On-farm hatching systems for broiler chicks are increasingly used in practice. We studied whether or not performance, health and welfare aspects differed between commercial flocks hatched on-farm or in a hatchery (control).

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Parasite, 2021 The effects of gastrointestinal nematode infections and anthelmintic treatment on milk yields was compared between flocks with a low level (LL) of eggs per gram (epg) before partum and with a high level (HL).
