Published: July 2017

ContentsMicrobial environment is one of the important factors that affect the quality of preserved semen. Iodine methionine (IM), participating in the production and activation of metabolic enzymes, is a new type of amino acid chelate. To date, there has been no report to evaluate the effects of IM on boar semen preservation at 17°C. This study was designed to investigate the effects of IM on boar sperm quality and reproductive performance during liquid storage at 17°C and its antibacterial effect. Semen samples collected from six Yorkshire boars were diluted with basic liquid containing different concentrations of IM (0, 20, 40, 80, 160 and 320 μM). Subsequently, sperm motility, plasma membrane integrity and acrosome integrity were determined. After 6 days of preservation, the difference in microbial composition between control group and 80 μM IM group was compared using 16S rDNA sequencing, and the effects of IM on reproductive performance were also compared and analysed between the two groups. The results demonstrated that 20, 40 and 80 μM IM improved boar sperm motility, plasma membrane integrity and acrosome integrity. 80 μM IM was the optimum concentration. Conversely, 160 and 320 μM IM resulted in deleterious consequences to boar sperm quality compared to the control group and other treatment groups (p < .05). After 6 days of preservation, sperm motility, plasma membrane integrity and acrosome integrity were 56.0%, 51.8% and 59.4%, respectively. There was no significant difference in non‐return rate between the two groups (p > .05). But the litter size of 80 μM IM group was significantly higher than that of control group (p < .05). 80 μM IM inhibited proliferation of the phylum Proteobacteria and the genus Staphylococcus as well as Pseudomonas (p < .05). Further studies are required to understand the antibacterial mechanism of IM in liquid‐preserved boar semen.

Published: July 2017

AbstractDeforestation of tropical forests has led to widespread loss and extirpation of forest bird species around the world, including the Hawaiian Islands which have experienced a dramatic loss of forests over the last 200–800 years. Given the important role birds play in forest ecosystem functions via seed dispersal and pollination, a bird community's response to forest restoration is an important measure of the success of such conservation actions. We evaluated the bird response to reforestation at an important bird sanctuary, Hakalau Forest National Wildlife Refuge, Hawai′i Island, using 26 years of bird count data. We show that most species from within the diverse avian community increased significantly, but species colonized the restoration forest at different rates. Distance from intact forest and time since restoration were both important predictors of colonization rate, interacting such that for most species it took more time to colonize areas farther from the intact forest. In addition, both forest cover and understory diversity helped to explain bird densities, but the effect varied among species, suggesting that different habitat requirements may help drive variation in colonization rates. This article provides the first detailed evaluation of how a diverse community of birds has responded to one of the largest, ongoing reforestation projects in Hawai′i.

Aims: The elastic properties of circumscribed tissues (e.g., tendons, lymph nodes, prostates, brain tumors) are of considerable clinical interest. The purpose of this study was thus to compare the Intra-/Inter-observer variation and accuracy in vitro of point shear wave elastography (pSWE) with that of 2D-SWE and to assess 2D-SWE’s precision with variable ROI (vROI) incircumscribed objects.Material and methods: Round targets (Elasticity QA Phantom Model 049) were examined for varying degrees of stiffness (8, 14, 45, and 80 kPa) and diameters (20/10 mm). Three ultrasound systems and four probes were applied (pSWE: Acuson/S3000 9L4/4C1 and Epiq7 C51, 2D-SWE: Aplio/500 PVT375BT). Three different ROIs were used, namely fixed ROI (fROI) and variable ROI: rectangular-best-fitted ROI, and round-best-fitted ROI. Each measurement was performed twice by four observers.Results: A total of 3,604 measurements were conducted. The intra-observer variation of 2D-SWE measurements indicated better agreement (Intraclass Correlation Coefficient (ICC) = 0.971; 95% CI=[0.945; 0.985]), than for the pSWE measurements (ICC = 0.872; 95% CI=[0.794; 0.92]). With both methods, the shear wave elastography applied showed low inter-observer variation: ICC = 0.980; 95% CI=[0.970; 0.987]. However, a significant difference was observed between fROI (pSWE) and vROI (2D-SWE) on circumscribed objects in terms of accuracy. The lowest degree of observationerror was detected in situations where the ROI was not “best fitted”, but placed within the target of 3mm from the border (target diameter: 20mm; mean relative error = 0.15).Conclusions: When estimating the elastic properties of circumscribed tissues, the different measurement techniques performed by commercial shear wave elastography systems reveal a strong susceptibility for observational errors, depending upon the fixed vs. variable ROI of the pSWE vs. 2D-SWE technique.

Published: July 2017

Papillary fibroelastomas (PFEs) are one of the most frequent primary cardiac tumors and occur more often in patients with hypertrophic obstructive cardiomyopathy (HOCM). PFEs have been linked to an increased risk of neurological events. We report a case of a 59-year-old woman with HOCM in whom echocardiography (transthoracic and transesophageal, using 2D and 3D techniques) revealed multiple masses in various locations in the left cardiac chambers. Surgical excision of the cardiac tumors and aortic valve replacement was performed and the pathologic report confirmed the diagnosis of PFEs. Patient followup using ultrasonography is crucial since recurrence is a possibility. Current cardiac ultrasound techniques are essential for diagnosing and for guiding the management of these conditions.
Fractal planetary rings: Energy inequalities and random field model
Authors: Malyarenko Anatoliy , Ostoja-Starzewski Martin 
Published: July 2017

This study is motivated by a recent observation, based on photographs from the Cassini mission, that Saturn’s rings have a fractal structure in radial direction. Accordingly, two questions are considered: (1) What Newtonian mechanics argument in support of such a fractal structure of planetary rings is possible? (2) What kinematics model of such fractal rings can be formulated? Both challenges are based on taking planetary rings’ spatial structure as being statistically stationary in time and statistically isotropic in space, but statistically nonstationary in space. An answer to the first challenge is given through an energy analysis of circular rings having a self-generated, noninteger-dimensional mass distribution [V. E. Tarasov, Int. J. Mod Phys. B 19, 4103 (2005)]. The second issue is approached by taking the random field of angular velocity vector of a rotating particle of the ring as a random section of a special vector bundle. Using the theory of group representations, we prove that such a field is completely determined by a sequence of continuous positive-definite matrix-valued functions defined on the Cartesian square [Formula: see text] of the radial cross-section [Formula: see text] of the rings, where [Formula: see text] is a fat fractal.
Electron beam irradiation of fluorinated graphene

Published: July 2017

Fluorinated graphene was irradiated by electron beam, and the changing of fluorinated graphene after electron beam irradiation was found by several detection techniques of Raman, electrical characterization and X-ray photoelectron spectroscopy (XPS). Raman spectra and electric characterization confirmed that the crystal structure and electrical performance of graphene was recovered partially after electron beam irradiation. XPS results indicated that the concentration of fluorine quickly dropped from 35% to 15% just after 30 min irradiation, and then dropped, slowly to 10% with the irradiation time to 150 min. The results indicate that stimulate fluorine desorption from fluorinated graphene used electron beam completely is difficult, which means a big challenge for ESD to fabricate all graphene electronics.
The De medicina, a 4th/5th-Century Poem of Gallo-Roman Origin, Rediscovered
Authors: Cilliers Louise 
Published: July 2017

Abstract
In 1536 a short poem with the title De medicina was published in Basel by Janus Cornarius in the editio princeps of Marcellus Empiricus’ De medicamentis liber.1 Cornarius based his edition on the Codex Laudunensis 4202 (9th/10th century), a manuscript which in the centuries after the publication suffered damage, losing inter alia the preface which contained the only evidence about the author of the work.3 In the course of the following centuries the authorship of the poem was variously ascribed to Vindicianus, Marcellus and Serenus Sammonicus, which gave rise to a protracted polemic in the 16th, 17th and 18th centuries. In this article the question of authorship will be discussed, followed by a translation and brief commentary on the poem.
High-Level Expression of Vascular Endothelial Growth Factor and its Receptors in an Aphthous Ulcer
Authors: Arbiser Jack L. , Johnson Darlene , Cohen Cynthia , Brown Lawrence F. 
Published: July 2017

Background: Aphthous ulcers are an extremely common disorder of unknown etiology. These ulcers cause significant morbidity through pain and interference with eating. Thalidomide, an angiogenesis inhibitor, is efficacious for the treatment of aphthous ulcers. Methods: In situ hybridization was performed on an idiopathic aphthous ulcer using probes specific for the angiogenesis factor vascular endothelial growth factor, and its receptors, in order to determine whether these ulcers are highly angiogenic. Conclusions: Aphthous ulcers are highly angiogenic. Thalidomide may act to heal aphthous ulcers by inhibiting angiogenesis and promoting reepithelialization. Excess angiogenesis may inhibit reepithelialization in certain types of ulcers, and angiogenesis inhibitors may actually promote wound healing if ulcers are caused by excess angiogenesis.
Unusual Presentation of Angiocentric T-Cell Lymphoma Mimicking Perianal Abscess
Authors: Dashkovsky Igor , Cozacov Juan Carlos 
Published: July 2017

Background: Subcutaneous angiocentric T cell is a common form of cutaneous lymphoma localized within subcutis mimicking lobular panniculitis. It is rarely manifested as perianal skin lesion. Objective: To suggest that perianal T-cell lymphoma is a rare entity that should be included in the differential diagnosis of perianal infiltrate mimicking perianal abscess. Methods and Results: A 65-year-old woman presented with painful perianal infiltrate mimicking a perianal abscess. The pain lasted seven days and there was no evidence of fever. Bacterial examination of tissue of the infiltrate discovered Staphylococcus aureus. Angiocentric T-cell lymphoma was demonstrated on biopsy. Conclusion: Our case represented sequela of subcutaneous angiocentric T-cell malignant lymphoma with a complication of a secondary infection mimicking perianal abscess. In patients presenting with a perianal infiltrate without abscess, a malignant condition should be considered a differential diagnosis and a biopsy should be performed.
Transdermal and Skin-Targeted Drug Delivery
Authors: Merino Virginia , Alberti Ingo , Kalia Yogeshvar N. , Guy Richard H. 
Published: July 2017

Background: The application of therapeutic agents to the skin addresses three general objectives: (a) the treatment of a variety of dermatologic diseases; (b) the “targeted” delivery of drugs to deeper subcutaneous tissues, with a concomitant reduction in systemic exposure; and (c) socalled transdermal administration to elicit a systemic pharmacologic effect. Objective: Recently, significant progress towards all three goals has been recorded and the level of research and development activity remains high. We aim to discuss these advances from mechanistic and clinical standpoints. Results: For the topical treatment of skin disease, novel vehicles (e.g., stabilized, supersaturated systems and liposomal formulations) have led to dramatic improvements in local drug bioavailability. Transdermal delivery of drugs for systemic effect, though limited in terms of the number of compounds, is perhaps the most commercially successful (in terms of the number of products) of the controlled release technologies. Considerable activity continues to enhance drug delivery (and hence to extend the range of drugs for which transdermal delivery can be used). Existing patches use formulations that contain solvents and adjuvants capable of reducing the barrier function of the skin. Much effort is directed at iontophoresis (electrically enhanced transport), particularly for small peptides that are difficult to administer by other routes. “Reverse iontophoresis” may allow the extraction of glucose (without skin puncture) so that continuous, noninvasive monitoring of blood sugar in diabetics approaches realization. Conclusion: In the not too distant future, the skin may also play a role not only in drug delivery, but also with respect to measurements in clinical chemistry.

Role of an manager in a dual career of athletes
Authors: Gulak-Lipka Patrycja 
Published: July 2017

Many athletes begin their career at a very young age, joining then with varying degrees of success the role of an athlete and a student. In the initial stage of their sporting career it is hard to predict whether it will develop to the level of a career which will ensure a player with funds for a long period of time. Therefore, in parallel with their career, athletes should develop other competencies that will allow them at the end of a career switch smoothly to life after the end of the adventure with sport. During a career athletes can count on various types of support that help them achieve sporting goals, or those outside of the sport. Support usually comes from coaches, parents, sponsors, or even sports managers. Young athletes (especially those playing team sports) more often sign contract with an intermediary or sports manager, who for many years is responsible for leading their careers.In this article the author focuses on the role of a manager in a non-athletic development (education and professional development) of a player that he represents. The silhouette of sports managers will be presented as well as competences, their responsibilities and the expectations which they face during their work. Based on the interviews with the players and sports managers, it will be possible to demonstrate if the expectations of both parties are satisfied and, in particular, to what extent the expectations of athletes to managers in the area of support of their non-sport development are met. It has been shown that care and range of actions of a sports manager varies depending on the stage of player's career. They perform a number of activities not directly related to sport, which provide tranquility and peace of mind that allow for even greater focus on the development of their sports careers. Managers want to increase the importance of their work in the life of an athlete.
Techno - doping legal and ethical aspects
Authors: Kopczyk Renata 
Published: July 2017

Continuous fight for sport’s quality has been taking place throughout the last several decades, which is a result of morally weakened construction of sport. One of the most significant battles is taking place on legal field (but not only) and pertains to doping, which, in a way, has its roots in the aspiration for perfection, - "Citius Altius Fortius". However, this aspiration breaches legal regulations. Doping creates situations when sport no longer educates but corrupts. Fair play is vanishing, it is no longer the most valuable and prominent moral rule. Of course there is no doubt that doping is one of the highest threats to sports competition based on fair play basis. And techno-doping is one of the most controversial issues in sport. Legal aspect of techno-doping prevention in sport became one of the most significant and difficult issues of sports law.
The communication effects of sponsorship in local sports markets
Authors: Kowalski Sławomir 
Published: July 2017

Local sports market depends on the groups of stakeholders. One of them are the sponsors grouped around a particular club or sport. The problem that meet the organizers of sporting events or recreational activities is the inability to convince sponsors to the effectiveness of promotional activities based on the sport. Inability is due primarily to the fact that companies sponsoring do not use all aspects of the sponsorship and sometimes the club cannot indicate how it should be used. Meanwhile, the lasting effects of sponsorship can bring benefits not only its image but also financial, informational, promotional. The primary purpose of the article is to study the effect of the use of the communication by the sponsors local sports clubs. This study will be done by evaluating how the sponsors of these clubs to communicate the fact to support the outside. Space research will be websites of sports clubs from Częstochowa region and information from websites of their sponsors.Article will consist of theoretical and practical parts. In the theoretical part will be presented briefly the most important and latest information on modern forms of communication with the use in companies. The practical part of the study will fill your own. During the study it will be verified thesis that sponsors local sports clubs faint attach importance to communicate that fact to potential customers. In this way also it verifies opinion on the effectiveness of sponsorship and lack of ability to use image-supporting local sports clubs.The article is part of a multi-lane testing on the functioning of local sports clubs.

BACKGROUNDMedicare patients account for approximately 50% of hospital days. Hospitalization in older adults often results in poor outcomes.OBJECTIVETo test the feasibility and impact of using Assessing Care of Vulnerable Elders (ACOVE) quality indicators (QIs) as a therapeutic intervention to improve care of hospitalized older adults.DESIGNPost‐test only prospective intervention with a non‐equivalent retrospective control group.SETTINGLarge tertiary hospital in the greater New York Metropolitan area.PATIENTSHospitalized patients, 75 years and over, admitted to medical units.INTERVENTIONA checklist, comprised of four ACOVE QIs, administered during daily interdisciplinary rounds: venous thrombosis prophylaxis (VTE) (QI 1), indwelling bladder catheters (QI 2), mobilization (QI 3), and delirium evaluation (QI 4).MEASUREMENTSVariables were extracted from electronic medical records with QI compliance as primary outcome, and length of stay (LOS), discharge disposition, and read‐missions as secondary outcomes. Generalized linear mixed models for binary clustered data were used to estimate compliance rates for each group (intervention group or control group) in the postintervention period, along with their corresponding 95% confidence intervals.RESULTSOf the 2,396 patients, 530 were on an intervention unit. In those patients not already compliant with VTE, compliance rate was 57% in intervention vs 39% in control (P < .0056). For indwelling catheters, mobilization, and delirium evaluation, overall compliance was significantly higher in the intervention group 72.2% vs 54.4% (P = .1061), 62.9% vs 48.2% (P < .0001), and 27.9% vs 21.7% (P = .0027), respectively.CONCLUSIONThe study demonstrates the feasibility and effectiveness of integrating ACOVE QIs to improve the quality of care in hospitalized older adults.
