Terahertz (THz) radiation has many far reaching applications—of specific interest is that many non-metallic and non-polar substances are transparent in the THz frequency range. This provides many practical uses for security purposes, where it is possible to detect and determine various substances that may be hidden or undetectable via conventional methods such as X-rays. In addition to this pro...

The aim of our study was to examine the effect of 3-isobutyl-1-methyl-xanthine (IBMX) and dibutyryl cyclic adenosine monophosphate (dbcAMP), stimulators of cAMP/protein kinase A-dependent intracellular signaling pathway, on reproductive function of gonadotropin-stimulated rabbit females. Ovarian cycle and ovulation in the control group were stimulated by PMSG (pregnant mare serum gonadotropin) ...

Biodegradation of 2-methylenebornane (2-MB) by Enterobacter cloaceae, which is one of the dehydration products of 2-methylisoborneol (2-MIB) led to 2-MIB, 2methylcamphene (2-MC) and an unidentifiable oxidation product, in addition to the previously reported camphor and lactonic compound. On the other hand, 2-MC, which is another dehydration product of 2-MIB was oxidatively degraded to fenchone ...

UNLABELLED This report presents findings of a community survey of 3,021 adolescents and young adults aged 14-24 years in Munich, Germany, carried out to determine the prevalence of use and abuse of and dependence on ecstasy, amphetamines and hallucinogens. The response rate was 71%. RESULTS (1) In 1995, 4% of the male and 2.3% of the female respondents aged 14-24 reported the use of ecstasy. ...

"Organic chemical nomenclature is an infuriating subject." So wrote Cahn in 1959. One of the fundamental differences between organic and inorganic chemistry is that carbon atoms have the property of Unking on to one another to form chains or rings. The ordinary inorganic molecular formula rarely contains more than ten atoms, but the organic molecule may number its component atoms in dozens, in ...

Various saccharides and related substances were mixed with carthamin in aqueous solutions and their effects on red colour stability compared. At a low temperature range (5 °C), monoand disaccharides contributed to preservation of the carthamin red colouration. No monoand disaccharides could relieve carthamin from being bleached at a high temperature (30 °C). Among poly­ saccharides and their de...
