Cross-Amplification and Validation of SNPs Conserved over 44 Million Years between Seals and Dogs
No full textHoffman J, Thorne MAS, McEwing R, Forcada J, Ogden R. Cross-Amplification and Validation of SNPs Conserved over 44 Million Years between Seals and Dogs. PLoS ONE. 2013;8(7): e68365.High-density SNP arrays developed for humans and their companion species provide a rapid and convenient tool for generating SNP data in closely-related non-model organisms, but have not yet been widely applied to phylogenetically divergent taxa. Consequently, we used the CanineHD BeadChip to genotype 24 Antarctic fur seal (Arctocephalus gazella) individuals. Despite seals and dogs having diverged around 44 million years ago, 33,324 out of 173,662 loci (19.2%) could be genotyped, of which 173 were polymorphic and clearly interpretable. Two SNPs were validated using KASP genotyping assays, with the resulting genotypes being 100% concordant with those obtained from the high-density array. Two loci were also confirmed through in silico visualisation after mapping them to the fur seal transcriptome. Polymorphic SNPs were distributed broadly throughout the dog genome and did not differ significantly in proximity to genes from either monomorphic SNPs or those that failed to cross-amplify in seals. However, the nearest genes to polymorphic SNPs were significantly enriched for functional annotations relating to energy metabolism, suggesting a possible bias towards conserved regions of the genome
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

The effect of melatonin implants on the response to the male effect and on the subsequent cyclicity of Rasa Aragonesa ewes implanted in April. Anim Reprod Sci,
No full textAbstract Rasa Aragonesa ewes were used to evaluate whether treatment with melatonin implants in spring could modify: (i) the response to the male effect in terms of oestrous behaviour and ovulation rate; and (ii) the maintenance of sexual activity and ovulation rate at medium term, i.e. over the next 306 days. On 12 April, 42 ewes were divided into two groups, with (M; n = 21) or without (C; n = 21) a subcutaneous implant containing 18 mg melatonin. On 17 May (day 0), three aproned rams were introduced to each group to induce a ram effect. Ewes were observed for oestrus daily. The rams were removed 40 days later after which one aproned ram was introduced daily. Oestrous detection continued until 28 February, 306 days after the first male-female contact. The ovulation rate was determined by endoscopy in the first three cycles after ram introduction and in September-October and January. Progesterone was assayed from blood samples taken on 6 May, 10 and from day 0 to day 22 after ram introduction. Luteal activity before ram introduction was seen in 33% (M) and 29 (C)% of the ewes, respectively. Significantly more M ewes showed oestrous behaviour during the first 40 days after ram introduction (M: 100%; C: 62%; P < 0.01). Similar differences were observed for ewes anovulatory at ram introduction (M: 100%, C: 47%; P < 0.01). These differences were maintained over the three oestrous cycles in both groups. Treatment with melatonin implants was without detrimental effect on cyclic functions in the following breeding season, after seasonal anoestrus. Melatonin treatment significantly increased (P < 0.05) the mean ovulation rate of the first (1.62 ± 0.11 versus 1.31 ± 0.13), second (1.78 ± 0.15 versus 1.36 ± 0.15) and third cycles (M: 1.73 ± 0.12 versus C: 1.27 ± 0.14). There was a significant interaction between the effects of cyclicity at day 0 and melatonin treatment on the ovulation rate in the first cycle (P < 0.05). The mean ovulation rates of both groups were similar at the beginning (September) and middle (January) of the subsequent breeding season. Overall, the results confirmed that melatonin implants, combined with the ram effect, * Corresponding author. Tel.: +34-976-761600; fax: +34-976-761612. E-mail address: [email protected] (F.

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Performance of turf‐type bermudagrass cultivars in the upper and lower limits of the European transition zone
No full text[EN]
Bermudagrass [Cynodon dactylon (L.) Pers.] is one of the most widely cultivated turfgrass species throughout the world. It has several important attributes, such as heat and drought tolerance, and one big disadvantage, which is susceptibility to cold temperatures. Although many seeded bermudagrass cultivars are widely used in Europe, research is warranted on new varieties released in recent decades. Two identical field studies were conducted in Valencia, Spain (39 degrees N lat) and Legnaro, Italy (45 degrees N lat) to evaluate the turfgrass quality, winter dormancy, and spring green-up of two new bermudagrass releases in Europe ('Arden 15' and 'MBG 002') and three older bermudagrasses ('Blackjack', 'Common', and 'Paul 1'). Even though bermudagrasses were successfully cultivated in the cooler temperature zone (45 degrees N lat), cultivars exhibited poorer establishment and longer winter dormancy as a consequence of the lower temperatures compared with those grown in the warmer temperature zone (39 degrees N lat). Cultivars Arden 15 and MBG 002 were able to mitigate the effects of low temperature that affected the older cultivars, especially during spring green-up, which is an essential characteristic when growing bermudagrass in the upper limit of the transition zone.The authors would like to acknowledge Semillas Dalmau Company in Valencia (Spain), Padana Sementi Elette s.r.l.
