Electrocardiographic Patterns: Their Diagnostic and Clinical Significance

Distribution patterns of Iranian species of Saxifraga with their phytogeographical significance

Numerical analysis of Saxifraga in Iran was carried out on the basis of morphological and chorological data. The cluster analysis confirmed that the genus in Iran includes two distinct groups: Group one consists of two subgroups, a) alpine Irano-Turanian endemic species (S. ramsarica, S. iranica, S. wendelboi, S. koelzii), and b) Euxino-Hyrcanian species (S. paniculata subsp. Cartilaginea, S. k...

Iridoid patterns of genus Plantago L. and their systematic significance.

The distribution of 14 iridoid glucosides in 14 Plantago L. species (44 samples corresponding to 18 taxa) was shown. P. tenuiflora and P. gentianoides were studied for iridoids for the first time. The iridoid patterns showed a good correlation with morphological and other chemical features of the representatives of genus Plantago. The studied species are grouped together according to the iridoi...

Periodic EEG patterns: importance of their recognition and clinical significance.

Periodic electroencephalographic (EEG) patterns consist of discharges usually epileptiform in appearance, which occur at regular intervals, in critical patients. They are commonly classified as periodic lateralized epileptiform discharges (PLEDs), bilateral independent PLEDs or BIPLEDs, generalized epileptiform discharges (GPEDs) and triphasic waves. Stimulus-induced rhythmic, periodic or ictal...

Vascular patterns of the mammalian testis and their functional significance.

Even a superficial examination of the testes of various animals, for example rat and rabbit, is sufficient to make obvious that there are fundamental differences in their vascular supply and that the vessels display remarkable complexity both in their venous and arterial course. That morphological differences may exist between different animals has long been realized; thus de Graff (1677) clear...
