AbstractThis study examines resource use (diet, habitat use, and trophic level) within and among demographic groups (males, females, and juveniles) of bottlenose dolphins (Tursiops truncatus). We analyzed the δ13C and δ15N values of 15 prey species constituting 84% of the species found in stomach contents. We used these data to establish a trophic enrichment factor (TEF) to inform dietary analysis using a Bayesian isotope mixing model. We document a TEF of 0‰ and 2.0‰ for δ13C and δ15N, respectively. The dietary results showed that all demographic groups relied heavily on low trophic level seagrass‐associated prey. Bayesian standard ellipse areas (SEAb) were calculated to assess diversity in resource use. The SEAb of females was nearly four times larger than that of males indicating varied resource use, likely a consequence of small home ranges and habitat specialization. Juveniles possessed an intermediate SEAb, generally feeding at a lower trophic level compared to females, potentially an effect of natal philopatry and immature foraging skills. The small SEAb of males reflects a high degree of specialization on seagrass associated prey. Patterns in resource use by the demographic groups are likely linked to differences in the relative importance of social and ecological factors.
The Treponema denticola AtcR LytTR domain‐containing response regulator interacts with three architecturally distinct promoter elements: implications for understanding the molecular signaling mechanisms that drive the progression of periodontal disease
Authors: Miller D.P. , Frederick J.R. , Sarkar J. , Marconi R.T. 
Published: May 2014

SummaryTreponema denticola is an oral spirochete and periopathogen that transitions from low abundance in healthy subgingival crevices to high abundance in periodontal pockets. The T. denticola response regulator AtcR harbors the relatively rare, LytTR DNA‐binding domain. LytTR domain containing response regulators control critical transcriptional responses required for environmental adaptation. Using a multi‐step bioinformatics approach, 26 strong lytTR recognition motifs were identified in the genome of T. denticola strain 35405. Electrophoretic mobility shift assays demonstrated that AtcR binds to these recognition motifs. High specificity–high affinity complexes formed with phosphorylated AtcR. The LytTR recognition sequences were found to exist in three distinct promoter architectures designated as LytTR1, LytTR2 and LytTR3 promoters. LytTR1 and LytTR2 promoters harbor σ54 binding sites. The functional diversity of the proteins encoded by the putative AtcR regulon suggests that AtcR sits at the top of a regulatory cascade that plays a central role in facilitating T. denticola's ability to adapt to changing environmental conditions and thrive in periodontal pockets.

ObjectiveTo evaluate minimally invasive treatment of clavicular fractures with cannulated screw.MethodsData of 65 patients who had undergone minimally invasive treatment with cannulated screws for clavicular fractures from April 2009 to October 2010 were retrospectively analyzed and compared with those of 65 patients with clavicular fractures who had been treated by the same surgeons with plates. In the study group, there were 41 males and 24 females, aged from 19–67 years (mean, 35.8 years). According to Craig's classification, there were 29 group 1 and 36 of group 2‐II. Neer scores were used to evaluate shoulder function and radiographs to assess fracture union.ResultsThe incision length was 4–5 cm in the cannulated screw group (CSG) and 10–11 cm in the reconstructive plate group (RPG). Radiographs showed bone union was achieved in both groups, the bone healing time being 13.2 ± 6.9 weeks in the CSG and 16.3 ± 8.7 weeks in the RPG. All patients were followed up for 6 to 20 months (average, 10.6 months). The average Neer score was 96.6 ± 3.4 in the CSG and 94.2 ± 5.8 in the RPG. In the CSG, screw loosening occurred in five, and fracture displacement in three. There was a significant difference in fracture healing time between two groups but not in Neer score.ConclusionMinimally invasive treatment of clavicular fractures with cannulated screws has the advantages of minimal invasion, short bone healing time, good clinical outcomes, and being relatively inexpensive.
Pollen competition between two sympatric Orchis species (Orchidaceae): the overtaking of conspecific of heterospecific pollen as a reproductive barrier

Published: May 2014

AbstractThe frequency of hybrid formation in angiosperms depends on how and when heterospecific pollen is transferred to the stigma, and on the success of that heterospecific pollen at fertilising ovules. We applied pollen mixtures to stigmas to determine how pollen interactions affect siring success and the frequency of hybrid formation between two species of Mediterranean deceptive orchid. Plants of Orchis italica and O. anthropophora were pollinated with conspecific and heterospecific pollen (first conspecific pollen then heterospecific pollen and vice versa) and molecular analysis was used to check the paternity of the seeds produced. In this pair of Mediterranean orchids, competition between conspecific and heterospecific pollen functions as a post‐pollination pre‐zygotic barrier limiting the frequency of the formation of hybrids in nature. Flowers pollinated with heterospecific pollen can remain receptive for the arrival of conspecific pollen for a long time. There is always an advantage of conspecific pollen for fruit formation, whether it comes before or after heterospecific pollen, because it overtakes the heterospecific pollen. The conspecific pollen advantage exhibited in O. italica and O. anthropophora is likely to result from the reduced germination of heterospecific pollen or retarded growth of heterospecific pollen tubes in the stigma and ovary. Overall, the results indicate that our hybrid zone represents a phenomenon of little evolutionary consequence, and the conspecific pollen advantage maintains the genetic integrity of the parental species.

The effect of soil solarization and Trichoderma harzianum on induced resistance to grey mould (Botrytis cinerea) and powdery mildew (Podosphaera xanthii) was studied. Plants were grown in soils pretreated by solarization, T. harzianum T39 amendment or both, and then their leaves were inoculated with the pathogens. There was a significant reduction in grey mould in cucumber, strawberry, bean and tomato, and of powdery mildew in cucumber, with a stronger reduction when treatments were combined. Bacillus, pseudomonad and actinobacterial communities in the strawberry rhizosphere were affected by the treatments, as revealed by denaturing gradient gel electrophoresis fingerprinting. In tomato, treatments affected the expression of salicylic acid (SA)‐, ethylene (ET)‐ and jasmonic acid (JA)‐responsive genes. With both soil treatments, genes related to SA and ET – PR1a, GluB, CHI9 and Erf1 – were downregulated whereas the JA marker PI2 was upregulated. Following soil treatments and B. cinerea infection, SA‐, ET‐, and JA‐related genes were globally upregulated, except for the LOX genes which were downregulated. Upregulation of the PR genes PR1a, GluB and CHI9 in plants grown in solarized soil revealed a priming effect of this treatment on these genes' expression. The present study demonstrates the capacity of solarization and T. harzianum to systemically induce resistance to foliar diseases in various plants. This may be due to either a direct effect on the plant or an indirect one, via stimulation of beneficial microorganisms in the rhizosphere.

Published: May 2014

AbstractObjectivesThe ‘healthy migrant effect’ (HME) hypothesis postulates that health selection has a positive effect on migrants' health outcomes, especially in the first years after migration. We examined the potential role of the HME by assessing the association between residence duration and disease occurrence.MethodsWe performed a historical prospective cohort study. We included migrants who obtained residence permits in Denmark between 1 January 1993 and 31 December 2010 (n = 114 331). Occurrence of severe conditions was identified through linkage to the Danish National Patient Register. Hazard Ratios (HRs) were modelled for disease incidence by residence duration since arrival (0–5 years; 0–10 years; 0–18 years) adjusting for age and sex.ResultsCompared with Danish‐born individuals, refugees and family reunited immigrants had lower HRs of stroke and breast cancer within 5 years after arrival; however, HRs increased at longer follow‐up. For example, HRs of stroke among refugees increased from 0.77 (95% CI: 0.66; 0.91) to 0.96 (95% CI: 0.88; 1.05). For ischaemic heart disease (IHD) and diabetes, refugees and family reunited migrants had higher HRs within 5 years after arrival, and most HRs had increased by end of follow‐up. For example, HRs of IHD among family reunited migrants increased from 1.29 (95% CI: 1.17; 1.42) to 1.43 (95% CI: 1.39; 1.52). In contrast, HRs for TB and HIV/AIDS showed a consistent decrease over time.ConclusionOur analyses of the effect of duration of residence on disease occurrence among migrants imply that, when explaining migrants' advantageous health outcomes, the ruling theory of the HME should be used with caution, and other explanatory models should be included.

Published: May 2014

SummaryGene–background interaction is a commonly observed phenomenon in many species, but the molecular mechanisms of such an interaction is less well understood. Here we report the cloning of a maize mutant gene and its modifier. A recessive mutant with a virescent yellow‐like (vyl) phenotype was identified in an ethyl methanesulfonate‐mutagenized population derived from the maize inbred line B73. Homozygous mutant maize plants exhibited a yellow leaf phenotype after emergence but gradually recovered and became indistinguishable from wild‐type plants after approximately 2 weeks. Taking the positional cloning approach, the Chr.9_ClpP5 gene, one of the proteolytic subunits of the chloroplast Clp protease complex, was identified and validated as the candidate gene for vyl. When introgressed by backcross into the maize inbred line PH09B, the mutant phenotype of vyl lasted much longer in the greenhouse and was lethal in the field, implying the presence of a modifier(s) for vyl. A major modifier locus was identified on chromosome 1, and a paralogous ClpP5 gene was isolated and confirmed as the candidate for the vyl‐modifier. Expression of Chr.1_ClpP5 is induced significantly in B73 by the vyl mutation, while the expression of Chr.1_ClpP5 in PH09B is not responsive to the vyl mutation. Moreover, expression and sequence analysis suggests that the PH09B Chr.1_ClpP5 allele is functionally weaker than the B73 allele. We propose that functional redundancy between duplicated paralogous genes is the molecular mechanism for the interaction between vyl and its modifier.

Published: May 2014

ObjectivesTo explore the views of optometrists, general practitioners (GPs) and ophthalmologists regarding the development and organisation of community-based enhanced optometric services.DesignQualitative study using free-text questionnaires and telephone interviews.SettingA minor eye conditions scheme (MECS) and a glaucoma referral refinement scheme (GRRS) are based on accredited community optometry practices.Participants41 optometrists, 6 ophthalmologists and 25 GPs.ResultsThe most common reason given by optometrists for participation in enhanced schemes was to further their professional development; however, as providers of ‘for-profit’ healthcare, it was clear that participants had also considered the impact of the schemes on their business. Lack of fit with the ‘retail’ business model of optometry was a frequently given reason for non-participation. The methods used for training and accreditation were generally thought to be appropriate, and participating optometrists welcomed the opportunities for ongoing training. The ophthalmologists involved in the MECS and GRRS expressed very positive views regarding the schemes and widely acknowledged that the new care pathways would reduce unnecessary referrals and shorten patient waiting times. GPs involved in the MECS were also very supportive. They felt that the scheme provided an ‘expert’ local opinion that could potentially reduce the number of secondary care referrals.ConclusionsThe results of this study demonstrated strong stakeholder support for the development of community-based enhanced optometric services. Although optometrists welcomed the opportunity to develop their professional skills and knowledge, enhanced schemes must also provide a sufficient financial incentive so as not to compromise the profitability of their business.
A study on the microstructural and magnetic properties of the Sr0.70-xBaxLa0.30Fe11.78Cu0.22O19 hexagonal ferrites
Authors: Yang Yujie , Liu Xiansong 
Published: May 2014

Hexagonal ferrite Sr 0.70-x Ba x La 0.30 Fe 11.78 Cu 0.22 O 19 (0 ≤ x ≤0.7) magnetic powders and magnets were synthesized by the ceramic process. The phase compositions of the magnetic powders were investigated by X-ray diffraction. There is a single magnetoplumbite phase in the magnetic powders with barium content (x) from 0 to 0.70. The micrographs of the magnets were observed by a field emission scanning electron microscopy. All magnets have formed hexagonal structures and the particles are distributed evenly. Magnetic properties of the magnets were measured by a magnetic properties test instrument. The remanence, intrinsic coercivity, magnetic induction coercivity and maximum energy product of the magnets continuously decrease with the increase of barium content (x).
RESOURCE UTILISATION ASSOCIATED WITH SINGLE DIGIT DUPUYTREN'S CONTRACTURE TREATED WITH EITHER SURGERY OR INJECTION OF COLLAGENASE CLOSTRIDIUM HISTOLYTICUM
Authors: Povlsen Bo , Shields Adrian M. , Bhabra Gev S. 
Published: May 2014

The gold standard treatment for Dupuytren's contracture is surgical excision of the cord. A non-surgical treatment with collagenase clostridium histolyticum injection is available but appears costly. Objectives: To provide data on resource consumption related to surgical and non-surgical treatment for Dupuytren's contracture. Design and Participants: Twenty patients with a single digit Dupuytren's contracture, 10 treated with surgical excision, and 10 treated with a single injection of collagenase. Measurements: Minutes spent in theatre, number of follow-up appointments, time to skin healing, and patients return to normal activities of daily living. Results: The injection group was significantly better regarding theatre time (p < 0.0001), follow-up appointments (p = 0.048), skin healing time (p < 0.001), and return to normal activities of daily living (p = 0.02) than the operated group. Conclusions: There are significant personal and health economic differences between the two methods of treatment which may influence local choice.
