Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Internal medicine
  • Genetics

The scientist’s investigation covers issues in Animal science, Nest, Perch, Flock and Litter. His study in the fields of Dust bathing under the domain of Animal science overlaps with other disciplines such as Furnished cages. His research ties Beak and Nest together.

The study incorporates disciplines such as Eggshell, Deep litter, Animal-assisted therapy and Anatomy in addition to Flock. He focuses mostly in the field of Litter, narrowing it down to matters related to Nest box and, in some cases, Veterinary medicine and Stocking. His Veterinary medicine research includes themes of Feather and Claw.

His most cited work include:

  • The notion of ethological need, models of motivation and animal-welfare (381 citations)
  • Evolutionary conservation of the clk-1-dependent mechanism of longevity: loss of mclk1 increases cellular fitness and lifespan in mice (263 citations)
  • Poultry Behaviour and Welfare (133 citations)

What are the main themes of his work throughout his whole career to date?

His main research concerns Animal science, Veterinary medicine, Nest, Cell biology and Litter. His Animal science research integrates issues from Ecology, Feather, Flock and Animal-assisted therapy. His Feather study integrates concerns from other disciplines, such as Pecking order and Beak.

His Veterinary medicine research is multidisciplinary, incorporating elements of Food intake and Food conversion. As a part of the same scientific family, Barry O. Hughes mostly works in the field of Cell biology, focusing on Matrix metalloproteinase and, on occasion, Matrix, Troponin I and Pathology. His research investigates the link between Litter and topics such as Nest box that cross with problems in Nest site.

He most often published in these fields:

  • Animal science (40.91%)
  • Veterinary medicine (15.91%)
  • Nest (13.64%)

What were the highlights of his more recent work (between 2012-2018)?

  • Cell biology (12.50%)
  • Matrix metalloproteinase (11.36%)
  • Intracellular (5.68%)

In recent papers he was focusing on the following fields of study:

Barry O. Hughes focuses on Cell biology, Matrix metalloproteinase, Intracellular, Mitochondrion and Doxorubicin. In general Cell biology study, his work on Sarcomere, Matrix and Nuclear localization sequence often relates to the realm of Oncostatin M, thereby connecting several areas of interest. He combines subjects such as Troponin I and Pathology with his study of Matrix metalloproteinase.

His research in Intracellular intersects with topics in Myocyte and Clinical trial. His research in Mitochondrion focuses on subjects like Membrane, which are connected to Extracellular matrix. His Oxidative stress research entails a greater understanding of Endocrinology.

Between 2012 and 2018, his most popular works were:

  • Sequential fractionation and isolation of subcellular proteins from tissue or cultured cells (81 citations)
  • Targeting MMP-2 to treat ischemic heart injury (47 citations)
  • MMP-2 is localized to the mitochondria-associated membrane of the heart (33 citations)

In his most recent research, the most cited papers focused on:

  • Gene
  • Genetics
  • Internal medicine

His primary scientific interests are in Matrix metalloproteinase, Genetics, Gene, Cytosol and Exome. His study in Matrix metalloproteinase is interdisciplinary in nature, drawing from both Extracellular matrix, Matrix, Cell biology and Membrane. His study in the field of Caenorhabditis elegans, Organism and Mutant also crosses realms of Gompertz function.

As part of his studies on Gene, Barry O. Hughes often connects relevant subjects like Longevity. His Cytosol investigation overlaps with other disciplines such as Molecular biology, Proteolysis, Nucleus, Intermediate filament and Nuclear matrix. His Exome study combines topics in areas such as Missense mutation, Genome, Compound heterozygosity and Allele frequency.
