It is well known that injury ofthe capitulum is both common and important in childhood. Although much has been written on the subject, the frequency and importance of premature fusion of the epiphysis has not been fully appreciated. Clinical material-Twenty-eight children suffering from injury to the capitular epiphysis were reviewed. The age at the time of injury varied from three to twelve ye...

A scalp mass surgically excised from a 4-year-old Korean boy was identified as a tick through histological observations. In sections of the mass, characteristic features of a tick, including its gross contour, cuticular structures, well developed musculature and salivary glands, and the capitulum, were discovered. In particular, the capitulum is anteriorly protruded, which strongly suggests tha...

A.L. Cabrera's treatment of Argentine Vernonias (Cabrera, 1944) included four members of his Section Lepidaploa, subsection Flexuosae, three of which were listed as occurring in Entre Rios Province (Cabrera, 1974). Two of these, V. cognata Less. and V. platensis (Spreng.) Less., were said to be closely related, di!ering from each other only in the number of #owers in the capitulum, diameter of ...

PURPOSE Carrying out the chemical composition and antiproliferative effects against cancer cells from different biological parts of Artemisia herba alba. METHODS Essential oils were studied by gas chromatography coupled to mass spectrometry (GC-MS) and their antitumoral activity was tested against P815 mastocytoma and BSR kidney carcinoma cell lines; also, in order to evaluate the effect on n...

A new deep-sea stalked barnacle, Vulcanolepas scotiaensis sp. nov. is described from hydrothermal vents at depths of 2400-2600 metres along segments of the East Scotia Ridge and from 1400 metres in the Kemp Caldera. Both locations are areas of volcanic activity that lie on the Antarctic-South American Ocean Ridge complex near the South Sandwich Islands. This discovery confirms a wide distributi...

This study was conducted to investigate the effects of different silicon supplements and postharvest treatments on growth and yield of gerbera in a greenhouse experiment. Silicon supplements were including potassium silicate at three concentrations (0, 140 and 200 mg L−1), sodium silicate at three concentrations (0, 50 and 100 mg L−1) and rice hull ash (RHA) at three concentrations (0, 50 and 1...
