recently multiple studies have shown that elevated homocysteine levels may be associated with ophthalmic vascular disease. to investigate the role of high plasma levels of homocysteine in the patients with retinal vein occlusion, 21 patients with retinal vein occlusion (rvo) and 20 age and sex matched controls without rvo were included in this retrospective case–control study. information regar...

Relative centricity RC values of vertices/atoms are calculated within the Distance Detour and Cluj-Distance criteria on their corresponding Shell transforms. The vertex RC distribution in a molecular graph gives atom equivalence classes, useful in interpretation of NMR spectra. Timed by vertex valences, RC provides a new index, called Centric Connectivity CC, which can be useful in the topologi...

: As a dentist, it is very important to know the occlusal relationship of primary dentition so that any malocclusion in permanent can be predicted at early stages and corrected accordingly by orthodontic treatments. The ideal occlusion spacing acts as mirror for prevalence dentition. aim study was assess relationships between canines molars spacings among group 3-6-year-old children. A total 12...
