A topological index of graph G is a numerical parameter related to G which characterizes its molecular topology and is usually graph invariant. In the field of quantitative structure-activity (QSAR)/quantitative structure-activity structure-property (QSPR) research, theoretical properties of the chemical compounds and their molecular topological indices such as the Randić connectivity index, at...

The atom–bond connectivity (ABC) index of a graph G is defined as

The division of diffuse large B-cell lymphoma (DLBCL) into germinal center B-cell-like (GCB) and activated B-cell-like (ABC) subtypes based on gene expression profiling has proved to be a landmark in understanding the pathogenesis of the disease. This study aims to identify a novel biomarker to facilitate the translation of research into clinical practice. Using a training set of 350 patients, ...

BACKGROUND Patients with severe aortic stenosis at increased surgical risk continue to experience compromised long-term survival despite successful transcatheter aortic valve implantation. We used time-related pathways in a multistate analysis to identify predictors of adverse long-term outcome in patients who underwent transcatheter aortic valve implantation. METHODS AND RESULTS In a cohort ...

AIM To compare the Ki-67 labelling index determined using the enhanced peroxidase one step (EPOS) method with that using the standard ABC technique in pituitary tumours. METHODS Adjacent sections were immunostained using the EPOS and ABC techniques with the same Ki-67 antibody and same antigen retrieval method. RESULTS The labelling index measurements with the EPOS Ki-67 antibody were signi...

Background: Mobility difficulty in cancer survivors is the leading functional problem that impacts independence, participation, and quality of life. Purpose: This study examined the relationships of demographics, health-related variables, Timed Up and Go (TUG), and short version of Activities-specific Balance Confidence scale (ABC-6) with respect to mobility limitations in older cancer survivor...

The concept of Zagreb eccentricity indices ( 1 E and 2 E ) was introduced in the chemical graph theory very recently. The eccentric connectivity index ( ) c ξ is a distance-based molecular structure descriptor that was used for mathematical modeling of biological activities of diverse nature. The second geometric-arithmetic index 2 ( ) GA was introduced in 2010, is found to be useful tool in QS...

the present study was designed to determine the effect of different levels of body mass index (bmi) on fundamental motor skills in 6-year-old children of isfahan city. for this purpose, fundamental motor skills of 19 underweight children (grade 3 thinness) and 19 children with normal weight and 19 overweight children who were matched according to their gender and socioeconomic background were a...

Chondroitinase ABC (C-ABC) is expected to be a novel agent for chemonucleolysis. The effect of C-ABC was investigated by magnetic resonance (MR) and radiograph. C-ABC was administered into the lumbar intervertebral disks on the clinically normal beagles (n=5), in a dose of 50 microl (12.5 units as C-ABC). MR scans were performed pre-dose, and 1, 3, 7, 14 and 28 days after administration of C-AB...
