The Padmakar-Ivan (PI) index is a Wiener-Szeged-like topological index which reflects certain structural features of organic molecules. The PI index of a graph G is the sum of all edges uv of G of the number of edges which are not equidistant from the vertices u and v. In this paper we obtain the second and third extremals of catacondensed hexagonal systems with respect to the PI index.

Neandertal faces have been described as being derived with respect to their overall length or degree of anterior projection. A comparison of cranial and mandibular indicators of lower facial projection across archaic and modern Homo indicates that Neandertal facial lengths on average are similar to those of preceding archaic Homo and principally contrast with those of recent humans. Neandertal ...

Santiago Ramón y Cajal was not only a great scientist but he was also a dedicated teacher who managed to create his own School in Spain. Cajal was active at the end of the XIX and the beginning of the XX century, a period in which Ivan Petrovich Pavlov, another great contemporary scientist, also established a strong School in Russia. While these two acclaimed scientists shared a similar vision ...

The problem of initial singularity in cosmology, beyond the technical aspects, set the insurmountable limits of every description purely dynamics of the universe. In this brief note we present the main conceptual aspects of the Archaic Universe cosmological program. The adoption of a de Sitter prespace as a structure of the quantum vacuum allows you to rethink the problem of time in cosmology b...

BACKGROUND: This uncontrolled open label study evaluated the effect of dipeptidyl peptidase-4 inhibitors (DPP-4i): sitagliptin and vildagliptin on augmentation index standardized for 75 beats per minute (cAiX@75), blood pressure (BP), lipid profile and high-sensitivity C-reactive protein (hsCRP) in patients with type 2 diabetes mellitus (T2DM). METHODS: Fifty-one well-regulated T2DM patients we...

At the 44th and 51st meetings of JECFA, reference was made to the requirement for the results of a reproductive toxicity study on a substance complying with the specification for curcumin. The Report of the 51st meeting of JECFA also asked for information on the need and technological justification for alternative solvents for use in the current manufacturing processes of curcumin. The Call for...

PURPOSE To compare three commonly used retinal vessel caliber measurement software systems, and propose an algorithm for conversion between measurement systems. METHODS We used 120 retinal photographs to evaluate the agreement between three commonly used software (Retinal Analysis [RA], Integrative Vessel Analysis [IVAN], and Singapore I Vessel Assessment [SIVA]). Bland-Altman plots were used...
