Branching morphogenesis is a fundamental process in the development of the kidney. This process gives rise to a network of ducts, which form the collecting system. Defective branching can lead to a multitude of kidney disorders including agenesis and reduced nephron number. The formation of branching tubules involves changes in cell shape, cell motility, and reorganization of the cytoskeleton. ...

Internal iliac artery (IIA) shows frequent variations in its branching pattern. We saw variations in the branching pattern of right IIA in a male cadaver. The IIA divided into anterior and posterior divisions. The branches of the anterior division included umbilical artery, inferior vesical artery, obturator artery. The other branches arose from posterior trunk such as iliolumbar, lateral s...

The stability and stoichiometry of β(3)-peptide bundles is influenced by side-chain identity. β(3)-peptides containing β(3)-homoleucine on one helical face assemble into octamers, whereas those containing β(3)-homovaline form tetramers. From a structural perspective, the side chains of β(3)-homoleucine and β(3)-homovaline differ in terms of both side-chain length and γ-carbon branching. To eval...

The effects of long chain branching (LCB) degree on the shear-induced isothermal crystallization kinetics of a series of LCB polylactides (LCB PLAs) have been investigated by using rotational rheometer, polarized optical microscopy (POM) and scanning electron microscopy (SEM). Dynamic viscoelastic properties obtained by small-amplitude oscillatory shear (SAOS) tests indicate that LCB PLAs show ...

Glycolipids form materials of considerable potential for a wide range of surfactant and thin film applications. Understanding the effect of glycolipid covalent structure on the properties of their thermotropic and lyotropic assemblies is a key step toward rational design of new glycolipid-based materials. Here, we perform molecular dynamics simulations of anhydrous bilayers of dodecyl β-maltosi...

Polyethylenes (PE) are the most commonly occurring ingredients for post-consumer recyclates (PCR). The structure–property relationships of different types model PE-based blends established using multiple thermo-rheological analyses. Although considered “simple”, complex behavior is experimentally demonstrated first time metallocene-catalyzed, linear, low-density polyethylenes (mLLDPE) with micr...

We investigate the long-time and long-range behavior of branching diffusion processes (starting with a single particle) in two different situations: when the branching potential has compact support and when it is constant. For compactly supported branching potentials, the qualitative behavior of the processes depends on the intensity of the branching. We analyze the super-critical case, when th...

Songs of songbird species such as Bengalese finch consist of sequences of syllables. While syllables are temporally stereotypical, syllable sequences can vary and follow complex, probabilistic transition rules. Recent experiments and computational models suggest that a syllable is encoded in a chain network of projection neurons in premotor nucleus HVC (proper name). Precisely timed spikes prop...

on the basis of experimental data a kinetic model for the heterogeneous interaction between alkylperoxyradicals and organic compounds in langmuir- hinshelwood approach at room temperature has been offered.the effect of oxygen on the kinetics of process in the presence, [o2]o = 1 x 1011 – 1.6 x 1012 molecules.cm-2, and absence of oxygen has been analyzed. over time the chain degenerate branching...
