BACKGROUND Patients with neuroendocrine tumors(NETs) of the gastrointestinal tract suffer frequently from chronic diarrhea. A well characterized medical advice containing zeolite(Detoxsan~? powder) was applied to patients suffered from therapyrefractory diarrhea either by its frequency or by watery stool, despite receiving standard pharmacotherapy according to the guidelines for carcinoid syndrome and comorbidities. Detoxsan~? powder acts as an adsorbent and might reduce significantly symptoms of diarrhea in patients suffering from *** To overcome the therapy-refractory diarrhea of patients with NETs by the zeolite containing medical advice Detoxsan~? *** A total of 20 patients(12 female and 8 male) suffering from diarrhea either by its frequency or from watery stool caused by NETs were included. in each patient,the diagnosis had been confirmed by histology and somatostatin receptors expression proven by positron emission tomography/computed tomography using Ga-68-labeled somatostatin analogs. All patients received standard-of-care pharmacotherapy and were additionally given Detoxsan~? powder as an extemporaneous drug containing 90% natural Cuban zeolite and 10% magnesium aspartate. Recommended daily dosage ranges between 3 g once to three times per day. Each day dose and bowel movements were documented by the patients themselves in a pre-defined table. Additionally to the bowel movements quantitative determinations of serotonin, urea, creatinine and single ions were performed within the serum of the patients by commercially available equipment used as a matter of routine in the *** All patients enrolled in this pilot study did not only suffer from NETs, but also from comorbidities and treatment-resistant diarrhea. There was insufficient control of diarrhea, most probably due to the secretion of hormones like serotonin produced by the slowly growing and highly differentiated NETs. All patients only took Detoxsan~? powder as an antidiarrhea

Leymus is a genus in the Triticeae tribe, Poaceae. The taxa of this genus are allopolyploid species which possess the Ns and Xm genomes. According to cytological, cytogenetic and molecular genetic analyses, some species of Hystrix and Elymus ought to be transferred to this genus. A world revision of the genus Leymus is needed. in this paper we summarize experimental results, provide a key to sections, species and varieties, and list all the taxa we recognize in Leymus with their synonyms. This synopsis is a new taxonomic system to be used for the revision of Leymus.

The thirty-three 5′ flanking conserved sequences of the known low-molecular-weight subunit (LMW-GS) genes have been divided into eight clusters, which was in agreement with the classification based on the deduced N-terminal protein sequences. The DNA polymorphism between the eight clusters was obtained by sequence alignment, and a total of 34 polymorphic positions were observed in the approximately 200 bp regions, among which 18 polymorphic positions were candidate SNPs. Seven cluster-specific primer sets were designed for seven out of eight clusters containing cluster-specific bases, with which the genomic DNA of the ditelosomic lines of group 1 chromosomes of a wheat variety ‘Chinese Spring’ was employed to carry out chromosome assignment. The subse-quent cloning and DNA sequencing of PCR fragments validated the sequences specificity of the 5′ flanking conserved sequences between LMW-GS gene groups in different genomes. These results suggested that the coding and 5′ flanking regions of LMW-GS genes are likely to have evolved in a concerted fashion. The seven primer sets developed in this study could be used to isolate the com-plete ORFs of seven groups of LMW-GS genes, respectively, and therefore possess great value for further research in the contributions of a single LMW-GS gene to wheat quality in the complex genetic background and the efficient selections of quality-related components in breeding programs.

Meteors are particles of space dust that enter the earth’s atmosphere and burnup, creating a streak of light in the night sky. Over 120 recognized meteor showersoccur during the year. Humans have recorded observations of meteor showers for atleast 3000 years. Within the last 50 years astronomers have begun to study meteorshowers with photography, video, radio, and radar equipment.

We have classified 11 species recently recognized as belonging to the genus Elymus into a resurrected and legitimate genus Campeiostachys Drobov according to the international Code of Botanical Nomenclature. Our action is based on the rationale of monophyly, discrimination, and practicality discussed in detail. Currently Elymus contains a vast number of species with different genomes which often, but not always, can be differentiated by cytological and molecular features, but are difficult to separate by traditional morphology, although an effort to do so is detailed and discussed. This difficulty can be attributed to the dominance effect of a particular genome on the other genome(s) present. Campeiostachys, with genome constitution StStHHYY, is a recent addition to a number of genera recently segregated out of Elymus, i.e. Douglasdeweya (StStPP), Kengyilia (StStPPYY), and Roegneria (StStYY, StStStStYY). A key to Campeiostachys taxa is provided, along with taxa descriptions, distribution, nomenclature, and cytology. Nineteen nomenclatural novelties, or combinations, resulted from this work, 10 species names, and nine varietal names.

A study was conducted on Cambisols in Northern Germany to analyze the effect of fast growing trees （Salix and Populus spp.） used in agroforestry on soil chemical and physical properties and also on endo- and ectomycorrhizal colonization of the fine roots. Representative plots of three trials, Giilzow （GUL）, Vipperow （ViP） and Rostock （ROS）, were used to measure the topsoil inventories at the very beginning and after six （GUL）, seven （ViP） and ten （ROS） years of afforestation with fast growing trees. The effect on soil organic carbon, plant available nutrients, reaction, bulk density, porosity and water conditions was analyzed, Arable soils without tree coppice were used as controls. Additionally, the endoand ectomycorrhizal colonization of two Salix and two Populus clones were investigated at one site （GUL） in 2002. The amounts of organic carbon in the topsoil increased significantly （P 〈 0.01） presumably induced by leaf and root litter and also by the lack of tillage. The soil bulk density significantly decreased and the porosity of the soil increased significantly （both P 〈 0.01）. The proportion of medium pores in the soil also rose significantly （P 〈 0.05 and 0.01）. Generally, afforestation of arable soils improved soil water retention. Ectomycorrhizas dominated the mycorrhizal formation of the Salix and Populus clones, with the accumulation of organic matter in the topsoil suspected of supporting the ectomycorrhizal formation. Thus, agroforestry with Salix and Populus spp. conspicuously affected chemical and additionally physical properties of the top layer of Cambisols within a period of six years.
