Crown-Size Profile Patterns and Presumed Evolutionary "Trends"

Crown-size profile pattern in trisomy G.

Effect of agenesis on the crown-size profile pattern.

Agenesis and hypodontia are associated with crown-size reduction in the remaining teeth (S. M. GARN ET AL, J Dent Res 41:717, 1962, Nature 200:488-489, 1963; J Dent Res 42:13441363, 1963; H. J. KEENE, Amer J Orth 50: 445-451, 1964; and K. HANIHARA ET AL, J Anthrop Soc Nippon 73:72-81, 1965). The question arises as to whether crown-size reduction associated with tooth number reduction is uniform...

Genetic basis of the crown-size profile pattern.

Although genetic control of crown diameters has been documented by a number of workers (R. H. OSBORNE ET AL, Amer J Hum Genet 10: 350-356, 1958; S. M. GARN ET AL, J Dent Res 44:228-242, 1965; D. W. LEWIS and R. M. GRAINGER, Arch Oral Biol 12:539-544, 1967; and D. H. GOOSE, J Dent Res 46:959-962, 1967), genetic involvement in crown-size patterning has not been ascertained for the whole dentition...

Evolutionary trends in body size of parasitic flatworms

Evolutionary trends in body size have been identified within several lineages, but not all have followed Cope’s rule, which states that average body size within a taxon tends to increase over time. In organisms such as parasites, space constraints may have shaped the evolution of body sizes, favouring small-bodied taxa capable of exploiting new niches. Here, the average adult body sizes of fami...

Fasting consequences during Ramadan on lipid profile and dietary patterns

Introduction: The aim was to assess the effects on lifestyle and lipid profile while fasting during holy month of Ramadan. Material and Methods: An interventional cohort study designed with 160 subjects who were fasting during Ramadan recruited from different mosques in Kermanshah. Data were collected in three stages at the beginning and at the end of Ramadan as well as one month following Rama...
