    Notizen: Abstract Several lines of evidence suggest that nicotine may be useful in treating the symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD). The current study was an acute, placebo-controlled double-blind experiment to determine whether nicotine might be useful as an alternative treatment of adults with ADHD symptomatology. Six smokers and 11 nonsmokers who were outpatient referrals for ADHD were diagnosed by DSM-IV criteria. Measures of treatment effect included the Clinical Global Impressions (CGI) scale, Hopkins' symptom check list (SCL-90-R), the Profile of Mood States (POMS), Conners' computerized Continuous Performance Test (CPT), the Stroop test, and an interval-timing task. The smokers underwent overnight deprivation from smoking and were given a 21 mg/day nicotine skin patch for 4.5 h during a morning session. The nonsmokers were given a 7 mg/day nicotine skin patch for 4.5 h during a morning session. Active and placebo patches were given in a counterbalanced order approximately 1 week apart. Nicotine caused a significant overall nicotine-induced improvement on the CGI. This effect was significant when only the nonsmokers were considered, which indicated that it was not due merely to withdrawal relief. Nicotine caused significantly increased vigor as measured by the POMS test. Nicotine caused an overall significant reduction in reaction time (RT) on the CPT, as well as, with the smokers, a significant reduction in another index of inattention, variability in reaction time over trial blocks. Nicotine improved accuracy of time estimation and lowered variability of time-estimation response curves. Because improvements occurred among nonsmokers, the nicotine effect appears not to be merely a relief of withdrawal symptoms. It is concluded that nicotine deserves further clincal trials with ADHD.

    Notizen: Abstract Two types of sinasin, a rice-based fermented kanuri flat bread, were prepared and evaluated for their nutrient content and nutritional qualities. The preparation of the sinasin entailed using ‘traditional’ and ‘developed’ methods. The nutritional qualities of the products were evaluated in Wistar-strain albino rats using the Food Efficiency Ratio (FER), and Protein Efficiency Ratio (PER) methods. There was a higher protein content (11.11 percent) in the traditional sinasin than in the developed sinasin (9.93 percent). However, a one-way analysis of variance indicated no significant difference in FER, but a significantly different mean PER (p〈0.01) of 1.3 and 1.5 for the traditional and developed sinasin respectively. The two methods of preparation of the sinasin, their nutrient composition and nutritional qualities are described in this paper.

    Notizen: Oligosilsesquioxanes (OSS) may be considered as molecular sections of silica. The incompletely condensed (cy-clopentyl)7T7(OH)3 (T = SiO3/2) has been used to generate a phosphine-functionalized T8-OSS system by reaction with 2-(trichlorosilyl)diphenylphosphinoethane. The resulting model molecule (cyclopentyl)7T8(CH2)2PPh2 (1) is well suited to coordinate to transition metal clusters via the phosphorous atom. We selected the tetrahedral bimetallic cluster [HFeCo3-(CO)12]. Depending on the stoichiometry, one or two phosphine ligands could be added to the cobalt atoms, with substitution of CO molecules. Owing to the cyclopentyl substituents, the resulting complexes [HFeCo3(CO)11{Ph2P(CH2)2T8-(cyclopentyl)7}] (2) and [HFeCo3-(CO)10{Ph2P(CH2)2T8(cyclopentyl)7}2] (3) are soluble in numerous organic solvents. Therefore, they could be completely characterized by 1H, 13C, 29Si, and 31P NMR spectroscopy.
