  1. Theoretical study on the bactericidal nature of nanopatterned surfaces

    Journal of Theoretical Biology 385:1 (2015) PMID 26343860

    A natural biomaterial has been discovered with bactericidal activities, which is mainly attributed to its nanopatterned surface structure. The surface of Clanger cicada (Psaltoda claripennis) wings has been identified as a natural bactericidal material, which has lead to the emergence ...
  2. Models for Allee effect based on physical principles

    Journal of Theoretical Biology 385:143 (2015) PMID 26343260

    We propose some models of single species with Allee effect based on physical principles. A method is used to obtain the expression for the per capita growth rate (a macroscopic information) starting from the characteristics of interactions between the individuals (a microscopic informa...
  3. Progressive alignment of genomic signals by multiple dynamic time warping

    Journal of Theoretical Biology 385:20 (2015) PMID 26300069

    This paper presents the utilization of progressive alignment principle for positional adjustment of a set of genomic signals with different lengths. The new method of multiple alignment of signals based on dynamic time warping is tested for the purpose of evaluating the similarity of d...
  4. Cultural evolution of hinoeuma superstition controlling human mate choice: The role of half-believer

    Journal of Theoretical Biology 385:40 (2015) PMID 26334475

    In this study, we used a cultural dynamic model to explain the persistence of the hinoeuma superstition in traditional Japan. Men with this superstition avoid marrying women born in a hinoeuma year (or hinoeuma-women). Parents avoided childbirth during the last hinoeuma year out of the...
  5. Computational assay of Zanamivir binding affinity with original and mutant influenza neuraminidase 9 using molecular docking

    Journal of Theoretical Biology 385:31 (2015) PMID 26341387

    Based upon molecular docking, this study aimed to find notable in silico neuraminidase 9 (NA9) point mutations of the avian influenza A H7N9 virus that possess a Zanamivir resistant property and to determine the lead compound capable of inhibiting these NA9 mutations. Seven amino acids...
  6. Exploring the structure and conformational landscape of human leptin. A molecular dynamics approach

    Journal of Theoretical Biology 385:90 (2015) PMID 26342543

    Leptin is a hormone that regulates energy homeostasis, inflammation, hematopoiesis and immune response, among other functions (Houseknecht et al., 1998; Zhang et al., 1995; Paz-Filho et al., 2010). To obtain its crystallographic structure, it was necessary to substitute a tryptophan fo...
  7. Front propagation speeds of T7 virus mutants

    Journal of Theoretical Biology 385:112 (2015) PMID 26300067

    We propose a new reaction–diffusion model with an eclipse time to study the spread of viruses on bacterial populations. This new model is both biologically and physically sound, unlike previous ones. We determine important parameter values from experimental data, such as the one-step g...
  8. The dynamics of temperature and light on the growth of phytoplankton

    Journal of Theoretical Biology 385:8 (2015) PMID 26301719

    Motivated by some lab and field observations of the hump shaped effects of water temperature and light on the growth of phytoplankton, a bottom-up nutrient phytoplankton model, which incorporates the combined effects of temperature and light, is proposed and analyzed to explore the dyn...
  9. Neutrophil dynamics during concurrent chemotherapy and G-CSF administration: Mathematical modelling guides dose optimisation to minimise neutropenia

    Journal of Theoretical Biology 385:77 (2015) PMID 26343861

    The choice of chemotherapy regimens is often constrained by the patient's tolerance to the side effects of chemotherapeutic agents. This dose-limiting issue is a major concern in dose regimen design, which is typically focused on maximising drug benefits. Chemotherapy-induced neutropen...
  10. Role of structural flexibility in the evolution of emerin

    Journal of Theoretical Biology 385:102 (2015) PMID 26319992

    Emerin is a short inner nuclear membrane protein with an LEM-domain at the N-terminal end and a transmembrane domain at the C-terminal end. The middle region of human emerin contains multiple binding motifs. Since emerin is often found in evolutionarily newer species, the functional co...
