Abstract
Aim To evaluate if adult persons with spina bifida (SB) who have urinary tract complications have cognitive difficulties that can be identified by neuropsychological tests. Methods All individuals with SB >= 18 years of age registered at a regional outpatient clinic (n = 219) were invited, of which, 154 persons were included. Neuropsychological assessment of their cognitive status was performed with Wechsler Adult Intelligence Scale (R)-Fourth Edition: Coding, Block design, Arithmetic's, FAS (word generation), Rey Auditory Verbal Test for learning, and delayed recall 30 min. Bladder and bowel function were assessed with questions used by the Nordic Spinal Cord Injury Registry (NSCIR) in structured interviews, by questionnaires, and by chart reviews. Results Average neuropsychological test results for this SB population was shown to be approximately 1 SDunder the median for the general population. The Coding test showed significantly lower test results as compared with the whole SB group in persons with urinary tract complications, especially urinary tract infections, reduced kidney function, dependent emptying of the bladder, and the bowel and accidental bowel leakage. The Arithmetic's test showed a significant difference between subgroups in all parameters except reduced kidney function whereas the other neuropsychological tests were significantly correlated with some but not all urological parameters. Conclusion We propose neuropsychological testing with primarily two tests to find those persons with SB who, due to cognitive challenges, might need extra support to minimize urological complications.

Abstract
The spindle tree (Euonymus europaeusL.) is a much-branched deciduous shrub or small tree. Its fruit capsules contain seeds with remarkably high content of oil interesting for industry, especially the 3-acetyl-1,2-diacyl-sn-glycerols (AcDAG) synthesized by a specific acetyl-CoA diacylglycerol acetyltransferase. The distribution and amount of individual triacylglycerols (TAG) and especially acetyl-triacylglycerols (AcDAG) inEuonymusfruit have previously been assigned to specific tissues. Using anatomical and microscopical observations, we studied the fruit morphology, and for the first time, we identified a more detailed allocation of oil bodies in individual tissue structures. Thin layer chromatography separation of extracts from immature and mature fruits confirmed TAG and AcDAG as the most abundant lipid classes in both endosperm and embryo, followed by fatty acids and polar lipids. The abundance of fatty acids was further studied in the TAG and AcDAG fractions using gas chromatography. Data revealed particular FAs in both fractions allocated in tissue-specific manner and/or as indicators of maturation ofE. europaeusseeds. While the abundance ofcis-vaccenic-, linoleic as well as alpha-linolenic acids in the AcDAG structures generally drop with maturation in both embryo and endosperm, content of oleic acid increases. Abundance ofcis-vaccenic acid in TAG was recorded in immature endosperm. For embryo, the abundance of stearic acid in AcDAG and oleic acid in TAG fraction was distinctive. Deeper understanding of underlying metabolic processes will be essential for targeted metabolic engineering and/or application for oilseed crops.
