Differential growth of body components among coexisting passerines in response to nest predation risk
… can exert strong selection pressures on growth strategies across taxa. Studies of growth responses need to consider multiple body components because components can compete for resources during growth in an integrated growth strategy. However, such studies are lacking and little is known …

Analysis of post-translational modifications of the blue light photoreceptor, phot1, by the CRL3NPH3 ubiquitin ligase complex
… redistribution of auxin, and initiation of a differential growth response (resulting in phototropic curvature). Loss-of-function genetic screens have identified several key proteins involved in phototropic signal-response, including the primary photoreceptors, phototropins 1 and 2 (phot1 and …

Limb cell behaviors in Monodelphis domestica growth and development: the effects of Fgf pathway activators and inhibitors
A fundamental question in biology is, “how is growth differentially regulated during development to produce organs of particular sizes?” Research in invertebrates has shown that answers to this question can be gained by studying how serially homologous organs of a single animal (e.g., Drosophila …

Identifying genetic variation in candidate genes for heat stress and association thereof with growth performance in dusky kob (Argyrosomus japonicus)
… change, and the association of heat stress and growth performance. As temperature increases, so does growth, but only up to a point. Once the threshold temperature is reached, growth is hindered following the induction of heat stress. Furthermore, since many genes involved in regulating heat …

The discovery of a novel peptide, QUB-2274, from the defensive skin secretion of Rana amurensis
… these tests, QUB-2274 was found to exhibit differential growth-inhibitory activity towards the Gram-positive bacterium S.aureus, the Gram-negative bacterium E.coli, and the yeast C.albicans, but with a high haemolytic activity. It also had a strong anti-proliferative effect on the four …

Human canalization and female growth buffering with Drosophila as a model organism
… biological processes may lead to instances of differential growth outcomes among boys and girls. The causes of such differences may be misinterpreted when examining health and nutrition survey data and are deserving of inspection. This research utilizes an evolutionary female canalization model …

Three-dimensional assessment of facial morphology in infants with cleft lip and palate
Differential growth was demonstrated between facial features and within some facial features. In particular, the columella, nostrils and philtrum did not grow significantly after surgery, although this would be considered normal in the age group studied. Facial growth in children with UCL and UCLP …

Disciples of the state : secularization and state building in the former Ottoman World
… integration and coöptation spawned a dynamic of differential growth that severely weakened religious institutions. When religious institutions were weakened in this way in the 19 th century, it became possible for states to exert full control over the religious establishment upon independence, …

A new twist on black holes: the role of black hole spin in galaxy formation.
… in the AGN population, in terms of the differential growth with redshift of the space density of faint and bright AGN. This arises naturally from the interplay between the different accretion channels that drive the growth of BHs. The predictions of our model are extended to 6 < z < 20 …

Characterization of inducible antibiotic production by streptomycetes isolated from hyper-arid environments
… despite inhabiting different locations.;However, differential growth inhibition of several indicator strains, e.g. Staphylococcus aureus and Enterococcus faecalis was observed between isolates of both locations. Furthermore, phenotypic analysis and hyper-spectral imaging revealed hidden diversity …

Superfetation in beef cattle
… Other explanations such as embryonic diapause or differential growth of twins have been suggested as more accurate descriptions of the cases reported as superfetation. The hypothesis of this study is that if a viable pregnancy can ensure maternal recognition in cattle, an asynchronous embryo can …

Early life history dynamics of a stocked striped bass (Morone saxatilis) population and assessment of strategies for improving stocking success in Smith Mountain Lake, Virginia
… of their largest percent increases in first-year growth, overwinter survival, and recruitment to age 1. Age-0 striped bass exhibited dissimilar patterns of dispersion and size-dependent spatial distribution as a result of differences in habitat availability between stocking sites and water …

Discovery and design of novel bioactive peptides from the skin secretion of Ranidae frogs
… Frog (Limnonectes fujianensis), displaying differential growth-inhibiting activity on different microorganisms, even multi-drug resistant bacteria. Most of the MIC values against Gram-positive bacteria like S. aureus, MRSA (NCTC 12493) and E. faecalis, were at 4 µM. Besides, QUB 2282 was …

Abscisic acid : interactions with auxin in the regulation of root growth under water deficit conditions
Water stress has been shown to inhibit shoot growth more than root growth (Sharp et al., 1988). Abscisic acid (ABA) has been shown to be involved in this differential growth response in maize (Zea mays L.) seedlings (Saab et al., 1990; Sharp et al., 1994). ABA accumulates in the elongation zone of …

Airborne multispectral and hyperspectral remote sensing techniques in archaeology: a comparative study
… the phenomena, whose occurrence relies upon the differential availability of moisture to a crop growing over buried archaeological remains, reflecting different soil depths and precipitation, to create differential growth patterns in times of moisture stress. Consistently successful aerial …

Differential Response of a Virginia Common Lambsquarters (Chenopodium album) Collection to Glyphosate
… Westmoreland County, Virginia, which exhibited a differential response to glyphosate treatments as compared to most other common lambsquarters. Plants from this site that survived glyphosate applications were collected in both 2002 and 2004. Greenhouse studies were conducted on F1, F2, and F3 …

Defining Epithelial Cell Fate Dynamics of the Oesophagus during Postnatal Development and Homeostasis
… model of rapid but restricted tissue growth, in which cells switch from a state of expansion to the steady state of homeostasis. In this project, I investigated the cellular and molecular mechanisms that govern this transition in the mouse oesophageal epithelium. Using wholemounting …

How the Heart Grows: From Multi-scale Data to a Multi-scale Model
… were used for a spatio-temporal analysis of growth during C-looping at the tissue and cellular levels, and with respect to each other. The experimental pipeline used in the chicken and rat embryo models resulted in time-course, multi-scale datasets. The chicken embryo dataset was then …
