The Convergence of Behavioral Biology and Operant Psychology: Toward an Interlevel and Interfield Science [PDF]

The Behavior Analyst, 1989
Behavioral biology and operant psychology have developed in parallel but separate paths since their origins in the 1930s. In the first three decades, both fields dealt with microscopic (or molecular) controlling variables and qualitative data. Since about 1960, both have primarily focused on macroscopic (or molar) controlling variables.

A Richer and More Diverse Future for Cell Biology [PDF]

, 2010
Our vision: within the next few decades the composition of the faculty of cell biology, and of all biological science departments, will reflect the diverse composition of the graduate students in those departments.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Operator identities for standard weighted Bergman shift and Toeplitz operators [PDF]

, 2013
We prove an operator identity for the shift operator in the scale of standard weighted Bergman spaces in the unit disc. This operator identity is then applied in the context of functional calculus for the shift operator and a characterization of harmonic

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

An Evolutionary Algorithm With Heuristic Operator for Detecting Protein Complexes in Protein Interaction Networks With Negative Controls

IEEE Access
Computational biology research faces a formidable challenge in the detection of complexes within protein-protein interaction (PPI) networks, critical for unraveling cellular processes, predicting functions of uncharacterized proteins, and diagnosing ...

Tunicates push the limits of animal evo-devo [PDF]

, 2011
The phylum to which humans belong, Chordata, takes its name from one of the major shared derived features of the group, the notochord. All chordates have a notochord, at least during embryogenesis, and there is little doubt about notochord homology at ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Towards molecular systems biology of gene transcription and regulation [PDF]

, 2010
Ten years after the determination of the RNA polymerase 11 structure, the basic mechanism of mRNA synthesis during gene transcription is known. In the future, the initiation and regulation of transcription must be studied with a combination of structural

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
