[(18)F]-5-Fluoro-5-deoxyribose ([(18)F]-FDR) conjugates much more rapidly than [(18)F]-FDG under mild reaction conditions to peptides and offers new prospects for mild and rapid bioconjugation for fluorine-18 labelling in PET imaging.
Variation of the methoxycarbonyl and C-18 substituents of the antiaddictive compound 18-methoxycoronaridine, and contraction of its isoquinuclidine ring segment, provided 15 congeners for SAR evaluation at opioid and alpha3beta4 nicotinic acetylcholine receptors. The opioid activities were relatively low, and the alpha3beta4 nicotinic acetylcholine receptor activities were found to correlate wi...
The cytokine IL-18 acts on the CNS both in physiological and pathological conditions. Its action occurs through the heterodimeric receptor IL-18Ralpha\beta. To better understand IL-18 central effects, we investigated in the mouse brain the distribution of two IL-18Ralpha transcripts, a full length and an isoform lacking the intracellular domain hypothesized to be a decoy receptor. Both isoforms...
A family is described in which 2 sibs had similar congenital abnormalities. Chromosome investigation of the mother and another child disclosed they were carriers of a translocation t(18;21)(q21;q22). The karyotype of one of the abnormal infants was determined and was found to be consistent with partial trisomy 18,46,XY,-21,+der (21),t(18;21) ((18pter leads to 18q21::21q22 leads to 2 lqter)mat.
The potential asymmetries in the birth-date distributions of youth soccer players across ten European countries (2175 age citations) were considered. First, we examined the birth-dates of players representing national youth teams in international competitions. Second, the birth-dates of players representing professional club teams in international youth tournaments were analysed. Kolmogorov-Smi...
واکنش تشکیل کمپلکس بین کاتیون با لیگاندهای درشت حلقوی دی سیکلو هگزیل18– کرون-6 و دی بنزو18–کرون–6 در مخلوط های دو جزئی 1,2– دی کلرواتان/ استونیتریل (dce/an)، 1,2 – دی کلرواتان/ متانول (dce/meoh)، 1,2– دی کلرواتان/ اتانول (dce/etoh) و 1,2– دی-کلرواتان/ اتیل استات (dce/etoac) در دماهای مختلف با استفاده از روش هدایت سنجی مورد بررسی قرار گرفت. نتایج به دست آمده نشان می دهند که در اکثر موارد، استوکی...
spastic paraplegia 18 is an autosomal recessive disorder characterized by motor dysfunction, joint contracture and mental retardation. we describe two families as three cases. case 1 is a 35-year-old woman with and spasticity and mild weakness in lower limbs. case 2 and 3 are a sister and brother aged six and two respectively. the older sister suffered from lower limb spasticity, equinovarus an...
