Drosophila tracheal terminal branches are plastic and have the capacity to sprout-out projections towards oxygen-starved areas, in a process analogous to mammalian angiogenesis. It was previously shown that this sprouting response involves the upregulation of the FGF homolog Branchless in hypoxic tissues, which binds its receptor Breathless on tracheal cells, thereby attracting the outgrowth of...

Hypoxia-Inducible Factor (HIF) prolyl hydroxylase domains (PHDs) have been proposed to act as sensors that have an important role in oxygen homeostasis. In the presence of oxygen, they hydroxylate two specific prolyl residues in HIF-a polypeptides, thereby promoting their proteasomal degradation. So far, however, the developmental consequences of the inactivation of PHDs in higher metazoans hav...

In this paper, we present our approach to introduce dynamism support to simulation environments, which adopts a Discrete Event System Specification (DEVS)-based modeling and simulation approach and builds upon previous work on Simulation Modeling Architecture (SiMA), a DEVS-based simulation framework developed at TUBITAK UEKAE. In the relevant literature there are already proposed solutions to ...

The Drosophila melanogaster gene archipelago (ago) encodes the F-box/WD-repeat protein substrate specificity factor for an SCF (Skp/Cullin/F-box)-type polyubiquitin ligase that inhibits tumor-like growth by targeting proteins for degradation by the proteasome. The Ago protein is expressed widely in the fly embryo and larva and promotes degradation of pro-proliferative proteins in mitotically ac...

The initial response of plants to aluminum (Al) is the inhibition of root elongation, while the transition zone is the most Al sensitive zone in the root apex, which may sense the presence of Al and regulate the responses of root to Al toxicity. In the present study, the effect of Al treatment (30 μM, 24 h) on root growth, Al accumulation, and properties of cell wall of two pea (Pisum sativum L...

BACKGROUND Although the potential survival benefit of bilateral internal mammary artery (BIMA) grafting in comparison with single internal mammary artery (SIMA) grafting has been emphasized by many investigators, the use of BIMA is still low in clinical practice in the absence of randomized trials and long-term results. In the current study, we aimed to assess if there is a long-term survival b...
