Methodological Approaches to the Design of Business Games and Definition of the Marine Specialist Training Content [PDF]

TransNav, 2012
Knowledge owned by marine specialists demand only in rare cases of extreme navigation situations. In this regard, the development of training game methods for actions in such situations is a very actual problem. The complex of professional business games

Fishers perceptions of ecosystem service change associated with climate‐disturbed coral reefs

People and Nature, 2021
Understanding ecosystem service change necessitates an understanding of the social and ecological dimensions of ecosystem services and how they contribute to the well‐being of different people. These empirical research gaps persist across the tropics and

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Reproductive aspects of Acanthurus chirurgus (Perciformes: Acanthuridae) captured by the artisanal fleet operating in Itamaracá Island, Pernambuco, Brazil

Scientia Marina
This study examined the reproductive biology of Acanthurus chirurgus through monthly collections from May 2016 to May 2018. A total of 505 specimens (317 males, 188 females) were analysed, with males having a larger total length than females (32.0 cm vs.

The Plasticity of Acipenser Baeri (Brandt, 1869) Species Expressed in Technological Bio-Indicators in Different Breeding Systems

Scientific Papers Animal Science and Biotechnologies, 2023
The undergoing of two experiments of breeding Acipenser baeri seedlings, in two intensive systems of sturgeon growing, placed in different locations, led to the establishment of sturgeons’ growing rates and of their survival percentages.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

The Influence of Wintering on Macronutrients in Fish Meat, in Species from a Wild Habitat

Scientific Papers Animal Science and Biotechnologies, 2023
To determine the macronutrient variations in fish meat at the end of the winter period compared to the start of wintering, 7 species from the Danube River were fished (Abramis brama, Ballerus sapa, Barbus barbus, Blicca bjoerkna, Gymnocephalus schraetser,

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...
