SYSTEMATICS OF THE ZYGNEMATACEAE (CHLOROPHYCEAE). III. TRANSEAU COLLECTION OF THE ZYGNEMATACEAE: AN OLD COLLECTION WITH MODERN USES

Edgar Nelson Transeau, botanist-ecologist-phycologist, accumulated a worldwide collection of algal specimens for the compilation of a monograph on the algal family Zygnemataceae, published in 1951. Following his death on January 26, 1960 this Collection remained at The Ohio State University, Columbus until 1978 when it was transferred to the University of Arizona, Tucson. A set of glycerine-preserved specimens on microscope slides is the major item of the Collection with the number of species represented as follows: Spirogyra (138), Mougeotia (52), Zygnema (45), Zygnemopsis (16), Sirogonium (9), Debarya (9), Zygogonium (4), Mougeotiopsis (1) and Entransia (1). All specimens of Pleurodiscus, Sirocladium, Temnogametum and Temnogyra are unidentified. With the Transeau Collection it was demonstrated that an old collection need not be an historical relic, but does have continued usefulness. Potential future use is a powerful justification for maintaining seemingly useless collections whose accumulation often represents the expenditure of untold time, effort and money on the part of many persons and institutions worldwide. Further, as man continues to alter his environment and species are destroyed, collections with long histories become increasingly more valuable. Specimens of the Transeau Collection were subjected to modern techniques, not available earlier, resulting in improved characterization of zygospore-wall structure by scanning electron microscopy and the determination of nuclear DNA by cytofluorometry.

Triatominae species of Suriname (Heteroptera: Reduviidae) and their role as vectors of Chagas disease

Nine species of Triatominae, representing three tribes and five genera, are currently known in Suriname. An annotated list of the species based on the collections of the Bureau of Public Health (Suriname), the National Zoological Collection Suriname and the National History Museum Leiden (the Netherlands) is provided. Additionally, the results of several years of opportunistic collection in two domestic environments are presented. The most common species are Rhodnius pictipes Stål, 1972, Rhodnius robustus Larrouse, 1972 and Panstrongylus geniculatus (Latreille, 1811). The significance of the species as vectors of Chagas disease in Suriname is discussed.     

ICPLQuant – A software for non‐isobaric isotopic labeling proteomics

The main goal of many proteomics experiments is an accurate and rapid quantification and identification of regulated proteins in complex biological samples. The bottleneck in quantitative proteomics remains the availability of efficient software to evaluate and quantify the tremendous amount of mass spectral data acquired during a proteomics project. A new software suite, ICPLQuant, has been developed to accurately quantify isotope‐coded protein label (ICPL)‐labeled peptides on the MS level during LC‐MALDI and peptide mass fingerprint experiments. The tool is able to generate a list of differentially regulated peptide precursors for subsequent MS/MS experiments, minimizing time‐consuming acquisition and interpretation of MS/MS data. ICPLQuant is based on two independent units. Unit 1 performs ICPL multiplex detection and quantification and proposes peptides to be identified by MS/MS. Unit 2 combines MASCOT MS/MS protein identification with the quantitative data and produces a protein/peptide list with all the relevant information accessible for further data mining. The accuracy of quantification, selection of peptides for MS/MS‐identification and the automated output of a protein list of regulated proteins are demonstrated by the comparative analysis of four different mixtures of three proteins (Ovalbumin, Horseradish Peroxidase and Rabbit Albumin) spiked into the complex protein background of the DGPF Proteome Marker.     

Optimal design of the Wilcoxon–Mann–Whitney‐test

In scientific research, many hypotheses relate to the comparison of two independent groups. Usually, it is of interest to use a design (i.e., the allocation of sample sizes m and n for fixed ) that maximizes the power of the applied statistical test. It is known that the two‐sample t‐tests for homogeneous and heterogeneous variances may lose substantial power when variances are unequal but equally large samples are used. We demonstrate that this is not the case for the nonparametric Wilcoxon–Mann–Whitney‐test, whose application in biometrical research fields is motivated by two examples from cancer research. We prove the optimality of the design in case of symmetric and identically shaped distributions using normal approximations and show that this design generally offers power only negligibly lower than the optimal design for a wide range of distributions.

Feeding strategies for <Emphasis Type="Italic">E. coli</Emphasis> fermentations demanding an enriched environment

The addition of a carbon nutrient feed to a fed-batch cultivation is often not enough to obtain satisfactory growth and/or production. In some cases, an additional feed with for example supplementary amino acids or complex media is required. This work presents the development of feeding strategies where more than one feed is required and the knowledge of the growth requirements is low. Simulations and cultivations with E. coli are shown using the proposed feed controllers which are based on a probing control concept. The strategies work well and they can be used to shorten the process development phase considerably.

Collection data, habitat data, and distribution maps are presented for each species.     

Management of otitic hydrocephalus; with particular attention to the effect of antibiotics

Otitic hydrocephalus as a complication of otitis media is probably not so rare as is generally assumed. The onset is insidious and first symptoms are vague. Even after signs of elevated cerebrospinal fluid pressure appear, differential diagnosis remains a difficult problem. On the basis of what is known of the pathologic features and clinical course of otitic hydrocephalus a plan for the prevention and management of this complication is suggested. In children and adolescents with a history of recurrent otitis media and other conditions likely to produce hydrocephalic disturbances, new episodes of otitis media must be treated along classical lines, notwithstanding supplementary use of antibiotics. After recovery, extended follow-up observation is required, which should include repeated ophthalmoscopic examinations. A finding of changes in the eyegrounds calls for neurologic evaluation. Energetic treatment, particularly daily spinal taps, may prevent ultimate blindness.
