Principal component analysis of variation pattern among Cola nitida, Cola acuminata (Sterculiaceae) and their interspecific hybrids
Authors: Adebola P. O. 
Published: August 2010

AbstractMorphological variation among selected accessions of Cola nitida (Vent.) Schott & Endl., C. acuminata (P. Beauv.) Schott & Endl. and their interspecific hybrids were studied at Cocoa Research Institute of Nigeria, Ibadan using Principal Component Analysis (PCA) and Average Cluster Linkage Analysis (ACLA). Measurements were taken on 30 vegetative and floral characters and the data obtained were subjected to statistical analysis. The results from both methods showed that the three groups of plants were morphologically similar but separable. The PCA revealed that the first five principal component axes accounting for 71.78% of the total variation with the first two axes accounting for 31.93% and 18.72% respectively. The major characters which account for the variation among the two species and their hybrids were peak flowering period, leaf shape, tree height, number of primary leaf veins, proportion of female flowers, leaf blade length and extent growth of twig.

AbstractDie Epidermis von Odontopteris subcrenulata aus dem Stefan (Oberkarbon) des Beckens von Blanzy Montceau (Zentralfrankreich) wird beschrieben. Die epidermale Anatomie von O. subcrenulata ist in vielen Aspekten mit der anderer odontopteridischer Taxa (z. B. Lescuropteris genuina, Odontopteris minor f. zeilleri, O. reichiana) vergleichbar, weist jedoch einige charakteristische Eigentümlichkeiten auf. Ein besonderes Merkmal der Epidermis von O. subcrenulata sind sekundäre, offenbar altersbedingte Veränderungen der stomatatragenden Bereiche der Fiederachsenunterseiten und der Interkostalbereiche der Fiederblättchenunterseiten durch zusätzliche Ein und/oder Auflagerungen, die auch die Spaltöffnungsapparate mit einschließen. Während junge Spaltöffnungsapparate offene äuβere Atemhöhlen besitzen, sind diese bei alten Spaltöffnungen fast vollständig verschlossen.

AbstractIt has been shown that the three Umbelliferae species, distributed in Eastern Himalaya, and previously referred to the genera Angelica and Peucedanum, are very similar in their characters, including carpological ones, to the genus Arcuatopterus, which was regarded as Chinese endemic. Three new nomenclatural combinations are proposed. A key is provided to the six species of Arcuatopterus now recognized, and a nomenclatural summary is also given. The generic area does not go limits beyond of the East Asian floristic subingdom (from Sichuan to Nepal, Sikkim and Khasia Hills).
Restionaceae seedlings: Morphology, anatomy and systematic implications
Authors: Linder H. P. , Caddick L. R. 
Published: August 2010

AbstractRestionaceae differ from most monocot families in having both epigeal and hypogeal germination. The green cotyledons associated with epigeal germination have a central vascular strand as found in most epigeal monocotyledons. In some genera the cotyledon may have a hairpin‐like structure, also described for Anthericaceae. The cotyledon of the hypogeal seedlings is short, without green pigment and largely remains embedded in the seed coat. Hypogeal germination is correlated with large, woody, indehiscent, frequently myrmecochorous nuts, while epigeal germination is found in species with smaller indehiscent nutlets or seeds, dispersed in a variety of ways. The primitive condition is most likely epigeal germination. In hypogeal seedlings of some African and Australian taxa an epicotyledonary rhizome is found between the primary root and the first leaves. Seedlings of African Restionaceae frequently have elongated culm internodes, whereas in the Australian species studied, internodes are very short, resulting in a cluster of seedling leaves. The leaf blades, which in most species are only found on the seedlings, are very simple anatomically. However, they appear to be unifacial, similar to the leaf blades of Anarthria (Anarthriaceae). The anatomical specialisations in the blades mirror those recorded for the culm anatomy. These observations are consistent with the hypothesis that Centrolepidaceae may be neotonous Restionaceae. They also corroborate the morphology of the African Restionaceae, and the presently accepted phylogeny of the African genera of Restionaceae.

Authors: Strassberger Verena , Trüssel Sabrina , Fugmann Tim , Neri Dario , Roesli Christoph 
Published: August 2010

AbstractThe in vivo perfusion of rodent models of disease with biotin derivatives and the subsequent comparative proteomic analysis of healthy and diseased tissues represent a promising methodology for the identification of vascular accessible biomarkers. A novel, triply charged biotinylation reagent, NHS‐β‐Ala‐(L‐Asp)3‐biotin, was synthesized and validated in terms of its applicability for in vivo protein biotinylation. Compared to sulfo‐NHS‐LC‐biotin, NHS‐β‐Ala‐(L‐Asp)3‐biotin exhibited a reduced membrane permeability and a preferential labeling of proteins localized in compartments readily accessible in vivo from the vasculature.

Published: August 2010

AbstractBackgroundIntrahepatic cholangiocarcinoma (IHC) is a rare liver malignancy with a rising incidence worldwide. Since no standard treatment has been established so far, the aim of this study was to assess the safety and efficacy of repeated liver resection and/or radiofrequency ablation (RFA) in selected cases with recurrent IHC.Patients and methodsThe outcome of 13 patients who had been treated at least once for recurrent IHC by repeated liver resection and/or RFA was retrospectively analyzed. A total of 12 repeated liver resections and 8 radiofrequency ablations were performed in these patients between 2002 and 2008.ResultsAfter a median follow‐up period of 28 months after primary liver resection (12–69 months), seven patients (54%) are still alive and three of these patients (23% of the entire cohort) are regarded as disease‐free. The median survival for all patients was 51 months (12–69 months). One‐ and three‐year survival after primary surgery was 92 and 52%, respectively, with an overall complication rate of 7.6%.ConclusionAccording to the present data, repeated liver resection and radiofrequency ablation are feasible in select patients with recurrent IHC. Both procedures can be regarded as safe and might lead to a prolongation of patient survival.
Expanding Roles: A Survey of Public Health Genetic Counselors
Authors: Powell Karen Potter , Hasegawa Lianne , McWalter Kirsty 
Published: August 2010

AbstractAccording to the 2008 National Society of Genetic Counselors (NSGC) Professional Status Survey (PSS), 31 genetic counselor respondents reported spending at least 50% of their time in the area of public health. The NSGC Public Health Special Interest Group (PHSIG) had 49 dues‐paying members in 2009. The purpose of this study was to identify the work settings and public health activities in which genetic counselors participate. A novel online survey was disseminated over the NSGC PHSIG Listserv. Forty‐one percent (n = 13) of public health genetic counselor respondents worked in a university medical system, while 53% (n = 17) were grant‐funded and held a non‐clinical appointment. The most common public health activities included educating healthcare professionals (82%) and community members (61%), research (55%), grant writing (55%) and grant administration (36%). Most respondents (82%) reported learning certain public health skills outside of their genetic counseling training programs. Differences in work settings were found, with a significantly greater percentage of public health genetic counselors working in government agencies. Genetic counselors have opportunities to become involved in public health activities as the scope of public health genetics grows. Furthermore, genetic counseling competencies are compatible with the Institute of Medicine's “10 Essential Public Health Services.” The NSGC and genetic counseling training programs are encouraged to offer more public health learning opportunities for genetic counselors and genetic counseling students interested in this specialty area.
Crayfish learning abilities: how does familiarization period affect the capture rate of a new prey item?
Authors: Ramalho Ricardo Oliveira , Anastácio Pedro Manuel 
Published: August 2010

AbstractThis study explores the effect of the length of learning period on capture rate of a previously unfamiliar prey by an invasive freshwater crayfish (Procambarus clarkii). Juvenile crayfish were subjected to different periods of contact (learning period) with a larvae prey (Chaoborus sp.). The length of the learning period significantly affected the number of prey consumed by the predator. Our results indicate that the naive crayfish require less than 12 h to learn to maximize capture rate of this prey. The learning coefficient, adopted in the present study, may be useful in exploring predation capabilities of alien species in newly invaded habitats.

Published: August 2010

AbstractThe use of waste oils/fats, as well as catalysts from waste materials, for producing biodiesel via transesterification have been of recent interest. As such, in the present work, the transesterification of chicken fat using crab and cockle shells as a catalyst was attempted. X‐ray diffraction (XRD) and electron dispersive X‐ray (EDX) results show that, upon thermal activation, both shells transformed into CaO, the active ingredient that catalyzes the reaction. In addition, the catalytic performance of individual shells as well as the combination of both shells in various ratios was similar. Under the optimal reaction conditions of 4.9 wt% catalyst amount and 0.55:1 methanol to oil mass ratio, methyl esters conversion above 98% was achieved in 3 h. The chicken fat methyl esters that were produced were found to meet several key specifications of biodiesel based on EN 14214 and ASTM D6751 test procedures.

Published: August 2010

Background Results of randomized controlled trials have shown that carotid endarterectomy poses greater perioperative risks to women than to men. There are limited studies regarding sex differences in carotid angioplasty and stenting. Objectives To compare male and female patients undergoing carotid stenting with regard to their intraprocedural complications and 30-day outcome. Methods We reviewed patients who underwent carotid stenting between 1997 and 2007 at our tertiary centre. Distal protection devices were used in all patients after 1999. Demographics, risk factors, intraprocedural complications, and 30-day outcomes were compared between female and male patients. Results Among 243 patients who underwent 255 procedures, 67 were women (27.6%). The mean (SD) age of the female patients was 72.2 ± 8.4 years and that of the male patients was 72.0 ± 9.6 years ( P = .83). The majority of patients had symptomatic carotid artery disease; 11 women (16.4%) and 30 men (16.0%) were asymptomatic. The following intraprocedural complications were noticed in female vs male patients: asymptomatic carotid and/or iliac dissections 7.5% vs 0% ( P = .001), minor stroke 0% vs 1.1% ( P = 1.00), major stroke 0% vs 0.5% ( P = 1.00), and cardiac dysrhythmias 3% vs 2.7% ( P = 1.00). At 30 days, the outcomes in women vs men were as follows: mortality 3.0% vs 3.2% ( P = 1.00), major stroke 3.0% vs 2.1 % ( P = .66), and minor stroke 3.0% vs 3.2% ( P = 1.00). Conclusion Although minor asymptomatic intraprocedural dissections were more common in women, we did not find any impact of sex on the 30-day outcome. We concluded that carotid stenting can be performed as safely in women as in men.
Doing good better? The differential subsidization of charitable contributions
Authors: Carmichael Calum M 
Published: August 2010

Abstract
This article introduces the practice and theory of subsidizing at different rates the private financial contributions made to different categories of charitable or publicly beneficial civic activities. It describes and compares the practices by which eight governments apply differential subsidies, and then summarizes guidelines for their design that can be inferred from optimal tax and expenditure theory. It does this in the hope that differential subsidies will receive greater attention in the public policy literatures that deal with financing the third-sector.
Population genetic structure of the prairie dog flea and plague vector, Oropsylla hirsuta
Authors: BRINKERHOFF R. JORY , MARTIN ANDREW P. , JONES RYAN T. , COLLINGE SHARON K. 
Published: August 2010

SUMMARYOropsylla hirsuta is the primary flea of the black-tailed prairie dog and is a vector of the plague bacterium, Yersinia pestis. We examined the population genetic structure of O. hirsuta fleas collected from 11 prairie dog colonies, 7 of which had experienced a plague-associated die-off in 1994. In a sample of 332 O. hirsuta collected from 226 host individuals, we detected 24 unique haplotype sequences in a 480 nucleotide segment of the cytochrome oxidase II gene. We found significant overall population structure but we did not detect a signal of isolation by distance, suggesting that O. hirsuta may be able to disperse relatively quickly at the scale of this study. All 7 colonies that were recently decimated by plague showed signs of recent population expansion, whereas 3 of the 4 plague-negative colonies showed haplotype patterns consistent with stable populations. These results suggest that O. hirsuta populations are affected by plague-induced prairie dog die-offs and that flea dispersal among prairie dog colonies may not be dependent exclusively on dispersal of prairie dogs. Re-colonization following plague events from plague-free refugia may allow for rapid flea population expansion following plague epizootics.

An alignment-free model for comparison of regulatory sequences
Authors: Koohy Hashem , Dyer Nigel P. , Reid John E. , Koentges Georgy , Ott Sascha 
Published: August 2010

AbstractMotivation: Some recent comparative studies have revealed that regulatory regions can retain function over large evolutionary distances, even though the DNA sequences are divergent and difficult to align. It is also known that such enhancers can drive very similar expression patterns. This poses a challenge for the in silico detection of biologically related sequences, as they can only be discovered using alignment-free methods.Results: Here, we present a new computational framework called Regulatory Region Scoring (RRS) model for the detection of functional conservation of regulatory sequences using predicted occupancy levels of transcription factors of interest. We demonstrate that our model can detect the functional and/or evolutionary links between some non-alignable enhancers with a strong statistical significance. We also identify groups of enhancers that are likely to be similarly regulated. Our model is motivated by previous work on prediction of expression patterns and it can capture similarity by strong binding sites, weak binding sites and even the statistically significant absence of sites. Our results support the hypothesis that weak binding sites contribute to the functional similarity of sequences.Our model fills a gap between two families of models: detailed, data-intensive models for the prediction of precise spatio-temporal expression patterns on the one side, and crude, generally applicable models on the other side. Our model borrows some of the strengths of each group and addresses their drawbacks.Availability: The RRS source code is freely available upon publication of this manuscript: http://www2.warwick.ac.uk/fac/sci/systemsbiology/staff/ott/tools_and_software/rrsContact: s.ott@warwick.ac.uk; hashem.koohy@warwick.ac.ukSupplementary information: Supplementary data are available at Bioinformatics online.
