Substrate Specificity and Peptide Motif Preferences of β-Lytic and L5 Proteases from <i>Lysobacter</i> spp. Revealed by LC-MS/MS Analysis. [PDF]

Int J Mol Sci
β-Lytic protease (Blp) and protease L5 are enzymes from Lysobacter bacteria with distinct proteolytic and bacteriolytic activities. To characterize their substrate specificity, we employed liquid chromatography–tandem mass spectrometry (LC–MS/MS ...

Environmental conditions and marine heatwaves influence blue whale foraging and reproductive effort. [PDF]

Ecol Evol, 2023
Our work links animal behavior and oceanography to provide insights into species life history and investigate the impacts of environmental change. We examine environmental correlates of blue whale vocalization patterns in Aotearoa New Zealand. Our results demonstrate the vulnerability of marine predator populations to marine heatwaves due to the links ...

Inversion of Rayleigh Wave Dispersion Curves via Long Short-Term Memory Combined with Particle Swarm Optimization. [PDF]

Comput Intell Neurosci, 2022
An essential step in surface wave exploration is the inversion of dispersion curves. By inverting dispersion curves, we can effectively establish the shear‐wave velocity model and obtain reliable subsurface stratigraphic information. The inversion of dispersion curves is an inversion problem with multiple parameters and multiple poles, and obtaining a ...

Vascularization of the gastrointestinal tract of the bottlenose dolphin (Tursiops truncatus, Montagu 1821). [PDF]

J Anat
Representative scheme of the gastrointestinal blood supply of the bottlenose dolphin. The duodenum is supplied by multiple duodenal arteries, the pacreaticoduodenal arteries do not supply the pancreas, and the caudal mesenteric artery can originate both from the cranial mesenteric artery or the aorta.

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps). [PDF]

Anat Rec (Hoboken)
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland
