Oral History Interview: James F. Summers and Ivy B. Summers
No full textMr. and Mrs. Summers taught school beginning in the decade after 1910. This interview deals with their teaching experiences in Kanawha County, West Virginia, and other West Virginia counties. At the time of the interview, Mr. and Mrs. Summers resided in Walton, West Virginia. Mrs. Summers was responsible for the formation of the Kanawha County hot lunch program. They both taught in sundry one-room schoolhouses.https://mds.marshall.edu/oral_history/1097/thumbnail.jp

Endomyzostoma neridae Summers, Al-Hakim & Rouse, 2014, n. sp.
No full textEndomyzostoma neridae n. sp. Summers & Rouse Fig. 2 F–G Holotype: AM W. 43447 hologenophore (1 spm: ½—in 70 % ethanol after formalin fixation; ½— 95 % ethanol). Dili, Banda Sea, Timor-Leste (8 ° 31 ' 15 "S, 125 ° 36 ' 46 " E). Collected using scuba on 19 September 2012 by Nerida Wilson and GWR. Genbank (COI—KM014169). Host. Cenometra bella (Hartlaub) (Colobometridae, Comatulida, Crinoidea). AM J. 25425. Genbank (COI—KM 491772). Paratypes: AM P. 90322 paragenophore (1 spm: in 70 % ethanol after formalin fixation). Collected on same host as holotype. Etymology. Named for Nerida Wilson, who collected this new species with GWR. Diagnosis and description. Located in cysts along ambulacral grooves of the host’s arms (Fig. 2 G). Holotype body folded along anterior-posterior axis, dorsal side inward (Fig. 2 F). Length ~ 5 mm, width ~ 3–3.5 mm (folded) following fixation. Mouth and cloaca terminal. Five pairs of very small parapodia with noticeable chaetae midway between midline and body margin (Fig. 2 F). Live color orange, cream in preservative. Remarks. Endomyzostomum neridae n. sp. is the first Endomyzostoma described from a crinoid host belonging to Mariametroidea. Remscheid (1918) recorded Endomyzostoma cysticolum (Graff, 1883) from a mariametroid, likely Amphimetra tesselata (AH Clark, 1911) in the Aru Islands (Indonesia). The drawing of the gall and specimen cannot be distinguished from E. neridae n. sp. and may represent an earlier record. Endomyzostoma cysticolum was originally described from Cape Frio, Brazil, associated with Comactinia meridionalis, a member of Comatulidae. See discussion above regarding other Endomyzostoma.Published as part of Summers, Mindi M., Al-Hakim, Iin Inayat & Rouse, Greg W., 2014, Turbo-taxonomy: 21 new species of Myzostomida (Annelida), pp. 301-344 in Zootaxa 3873 (4) on pages 305-306, DOI: 10.11646/zootaxa.3873.4.1, http://zenodo.org/record/25220

Mathematical and experimental approaches to the dimer catastrophe theory
No full textMulticopy plasmids rely on random distribution for stable inheritance by daughter cells at division. Threats to plasmid copy number increase the probability of plasmid loss, which can be detrimental to both plasmid and host. Plasmid dimers emerge through homologous recombination. Dimers have two independent origins of replication and thus have a replicative advantage and reduced copy number. Models of plasmid behaviour suggest that dimers would overtake a cell population, but that this can be prevented if they impose a small metabolic load, which has been observed in vivo. Plasmid ColE1 also contains a cer site, which allows for dimer resolution by XerCD site-specific recombination. A small RNA, Rcd, is expressed from the cer site in dimers and interacts with tryptophanase to increase the concentration of indole in the cell. It is proposed that, as indole inhibits cell division, Rcd imposes a checkpoint on the cell until plasmid dimers are resolved.
In this work, plasmid behaviour in a growing cell population was modelled stochastically in more detail than previous work. A plasmid replication model suggested that dimers replicate to more than half the average copy number of monomers, perhaps accounting for their increased metabolic load. A cell population model suggested that the presence of dimer-only cells decreased the average plasmid stability by less than in previous models, which used a fixed plasmid copy number. The rate of dimer resolution required to affect plasmid stability was unreasonably high, indicating the necessity of the Rcd checkpoint. The model thus suggested that the checkpoint may be an escape route for dimer-only cells rather than an immediate response to the emergence of an initial dimer.
The Rcd checkpoint itself was also subject to critical analysis. It was realised that neither inhibition of cell division nor cell growth were sufficient to assist dimer resolution; inhibition of plasmid replication was required. Experiments in vivo found that indole inhibited plasmid replication at a concentration that may be achievable endogenously. DNA gyrase was investigated as a component of the mechanism of this inhibition, and indole was found to inhibit its supercoiling activity in vitro
