True precocious puberty associated with phenylketonuria
No full textWe studied a girl with phenylketonuria who demonstrated signs of precocious puberty. At the age of 7.5 years she had premature telarche. Her height age was 7-9/12 years and her bone age was 9 years. Gonadotropin responses to LHRH administration were consistent with central precocious puberty. Elevated serum phenylalanine levels in this patient, due to poor compliance with the phenylalanine restricted diet, may be related to the early onset of puberty. © 1994 Freund Publishing House Ltd

Measurement of cognitive dynamics during video watching through event-related potentials (ERPs) and oscillations (EROs)
No full textEvent-related potentials (ERPs) and oscillations (EROs) are reliable measures of cognition, but they require time-locked electroencephalographic (EEG) data to repetitive triggers that are not available in continuous sensory input streams. However, such real-life-like stimulation by videos or virtual-reality environments may serve as powerful means of creating specific cognitive or affective states and help to investigate dysfunctions in psychiatric and neurological disorders more efficiently. This study aims to develop a method to generate ERPs and EROs during watching videos. Repeated luminance changes were introduced on short video segments, while EEGs of 10 subjects were recorded. The ERP/EROs time-locked to these distortions were analyzed in time and time-frequency domains and tested for their cognitive significance through a long term memory test that included frames from the watched videos. For each subject, ERPs and EROs corresponding to video segments of recalled images with 25% shortest and 25% longest reaction times were compared. ERPs produced by transient luminance changes displayed statistically significant fluctuations both in time and time-frequency domains. Statistical analyses showed that a positivity around 450 ms, a negativity around 500 ms and delta and theta EROs correlated with memory performance. Few studies mixed video streams with simultaneous ERP/ERO experiments with discrete task-relevant or passively presented auditory or somatosensory stimuli, while the present study, by obtaining ERPs and EROs to task-irrelevant events in the same sensory modality as that of the continuous sensory input, produces minimal interference with the main focus of attention on the video stream
Ekimia ozcan-secmenii (Apiaceae), a new species from Southwest Anatolia, Turkey
No full textEkimia ozcan-secmenii Senol & Eroglu sp. nov. (Apiaceae) is described from SW Turkey. E. ozcan-secmenii differs from its close affinity, E. bornmuelleri, by life form (monocarpic), petal and bracteole morphology, and mericarp features. These data were more supported by the results of nrDNA ITS sequences. The ML tree depicted based on phylogenetic studies aimed to reveal the closeness of the Laserpitium and Prangos species as well as the location the affinity of species in the genus Ekimia. The taxonomic situation of Prangos hulusi was also evaluated based on nrDNA ITS sequences. Since E. ozcan-secmenii is distributed in Sami Soydam Sandalcik hydroelectric power plant in Acipayam, Denizli, the population is threatening by flooding. Therefore, conservation programs are urgently recommended.TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [TBAG-108T851]The author would like to thank the curators of GAZI and EGE Herbaria for their helpful assistance.
