The rare and ancient coelacanth fish is “neutrally buoyant”, allowing it to perform its unusual headstand drift hunting technique – according to new research published in BMCBiology.
]), in 70% v/v EtOH at varying temperatures from 20 to 40 °C in steps of 5 °C was measured by incubating lipids with 70% v/v EtOH in separate containers on a thermoshaker using 3 h of shaking and 1 h of rest pr. temperature level. Samples of the lipid mixtures were drawn at each temperature and dried .
To measure absolute mass of bone mineral, lipid, and lean tissue for each segment of the specimen, slice-wise proportions of each substance was multiplied by the modeled density of the substance at the given depth . Lean muscle density [ ] was adjusted to pressure and temperature by the same factor as sea water. To measure absolute buoyancy for each segment, the volume displaced by the segment was multiplied by density of Comoran sea water at the given depth.

Induction, decay, and determinants of functional antibodies following vaccination with the RTS,S malaria vaccine in young children - BMC MedicineBackground RTS,S is the first malaria vaccine recommended for implementation among young children at risk. However, vaccine efficacy is modest and short-lived. Antibodies play the major role in vaccine-induced immunity, but knowledge on the induction, decay, and determinants of antibody function is limited, especially among children. Antibodies that promote opsonic phagocytosis and other cellular functions appear to be important contributors to RTS,S immunity. Methods We studied a phase IIb trial of RTS,S/AS02 conducted in young children in malaria-endemic regions of Mozambique. We evaluated the induction of antibodies targeting the circumsporozoite protein (CSP, vaccine antigen) that interact with Fcγ-receptors (FcRγs) and promote phagocytosis (neutrophils, monocytes, THP-1 cells), antibody-dependent respiratory burst (ADRB) by neutrophils, and natural killer (NK) cell activity, as well as the temporal kinetics of responses over 5 years of follow-up (ClinicalTrials.gov registry number NCT00197041). Results RTS,S vaccination induced CSP-specific IgG with FcγRIIa and FcγRIII binding activity and promoted phagocytosis by neutrophils, THP-1 monocytes, and primary human monocytes, neutrophil ADRB activity, and NK cell activation. Responses were highly heterogenous among children, and the magnitude of neutrophil phagocytosis by antibodies was relatively modest, which may reflect modest vaccine efficacy. Induction of functional antibodies was lower among children with higher malaria exposure. Functional antibody magnitude and the functional activity of antibodies largely declined within a year post-vaccination, and decay were highest in the first 6 months, consistent with the decline in vaccine efficacy over that time. Decay rates varied for different antibody parameters and decay was slower for neutrophil phagocytosis. Biostatistical modelling suggested IgG1 and IgG3 contribute in promoting FcγR binding and phagocytosis, and IgG targeting the NANP-repeat and C-terminal r
