Authors: Dobryanska G. M. , Yanovych D. O. , Shvets T. M. , Butsyak A. A. 
Published: May 2017

The paper presents results of investigations of zinc and manganese concentration in the water, bottom deposits and ichthyofauna of Yavoriv water reservoir, which was formed in 2002 in frames of project of Yavoriv sulfur quarry revitalization. Mentioned elements are characterized by wide spectrum of action in fish body, which, depending on their concentration, can be either physiologic or toxic. It was revealed, that concentration of Zn and Mn in the water of Yavoriv water reservoir varied considerably depending on place of samples taking. The lowest Zn concentration in the water was below 1 MPL (maximum permitted level), namely 0.6 µg/l, and the highest – more than 7 MPL (70.5 µg/l). Similar differences were observed concerning Mn concentration in the water – the range of determined values varied from 3.3 (0.3 MPL) to 48.6 µg/l. The same peculiarities of Zn and Mn distribution were estimated in regard to their content in bottom deposits. In particular, difference of Zn concentration in samples of bottom deposits was near 23 times – from 5.4 to 230.0 mg/kg depending on the point of samples taking. Mn content in bottom deposits varies from 61.5 to 1500 mg/kg. Zn and Mn concentration in skeletal muscles, gills and skin of perch and rudd didn’t exceed MPL regardless their content in the water and bottom deposits. In most of cases, gills accumulated these elements more than other investigated tissues.

Published: May 2017

This article presents data on dynamics of linear growth and weight rates of obroshynska gray and obroshynska gray natural groups geese, factional fluff content, correlation coefficients between body weight and body sizes and amount of feathers. It has been found that male and female individuals of obroshynska gray natural group geese dominated by live weight of obroshynska white natural group geese. Particularly, this advantage in 90 days aged males was 549.4 (P < 0.05), in 120 days aged males – 635.6 (P < 0.01) and in 180 days aged males – 422.6 (P < 0.05) g, in females – 177.0, 461.8 (P < 0.01) and 401.8 g respectively. It has been also revealed the obroshynska gray natural group geese domination by researched body sizes in all geese ages, but it was only reliable in some cases. Geese of both sexes in both natural groups were characterized by high fluff and feather level. We investigated age, sex and interbreed differentiation on fluff and feather levels in studied geese groups. It should be noted that fluff and feather level was better in white geese indicating a better fluff and feather quality. The correlation coefficients between body weight and overall fluff and feather levels in females of obroshynska gray natural group geese dependent on ages and fluff and feather levels were between -0.30 – +0.63, in males – between -0.51 – +0.68 and in obroshynska white natural groups geese coefficients were between -0.29 – +0.70 and -0.30 до +0.82 respectively. It has been found the correlations between geese body sizes and fluff and feather levels. In males and females geese from abroshynska gray natural group depenent on ages, body sizes and fluff and feather levels coefficients were -0.49 – +0.81 and -0.76 – +0.88, and for obroshynska white natural group geese – -0.49 – +0.90 and -0.65 – +0.65.

The aim of research was to study the duration the effectiveness and lifelong use of Ukrainian Black-Spotted dairy breed cows and the impact on these indicators of milk yield for the first and best of lactation. Research was carried out in Ltd. «Milk River» Sokal district, Lviv region. It is established, that the highly indices of life expectancy, productive use, lactation, number of lactations for life and the coefficient of economic use there were cows, milk yield for the first lactation of which was 3501–4000, for the best – 5001–5500 kg, but for the lifelong yields and the amount of milk fat – with the milk yield for the first lactation 4001–4500, for better – more than 6000 kg. Better by yields and the number of butterfat on one day of life, productive use and lactation were cows with milk yield for the first lactation of over 5500 kg, and for better – more than 6000 kg. Thanks to the correlation analysis is set different levels and the direction of indicators duration communication and the efficiency and lifetime use of experimental cows with their milk yield for the first lactation. The highest positive and significant correlation coefficients have been established between the animals yields for the first lactation and their yields (0.426–0.812) and the amount of milk fat (0.445–0.811) for a day of life, productive use and lactation. Negative, but probable links were between milk yield of cows for the first lactation and the duration of their life, productive use, lactation, number of lactations in life, the coefficient economic use. The greatest influence of cows yield for the first lactation had their yield and the amount of milk fat for a day of productive use (61.89 and 62.47% respectively) and lactation (54.97 and 56.44%) and the lowest – in a lifelong yield (2.01%) and the lifelong number of milk fat (1.97%). The largest predicted value had the links between the yields for the best lactation of cows and their lifelong milk yield, lifelong number of milk fat, yields and the amount of milk fat for a day of life and productive use and lactation. These links in all cases were close, highly reliable and were in the range 0.598–0.911. The lowest correlation coefficient, in addition improbable and negative, was observed between milk yield of cows for the best lactation and average fat content in milk for all lactation (-0.008). Significant influence of better lactation on the above mentioned indicators are confirmed by our calculation the indicators of influence power, which ranged from 39.53 to 77.68%. The lowest power of influence of this factor was observed in the average fat content in milk for all investigated lactation (1.02%).
Iodine deficiency in pigs and the solutions to the problem
Authors: Hunchak R. V. , Sedilo H. M. 
Published: May 2017

The articles provides an overview of literature dedicated to the study of iodine status in pigs and establishes an interrelation between the level of microelement in animal diet and the functional activity of thyroid gland. Close correlation between thyroid hormone levels in blood and the reproductive abilities and productiveness of pigs has been observed. Resulting thyroxin and triiodothyronine synthesis and metabolic disorders are among the most common causes of pathological states in animals, which are characterized by lower fertility, increased intrauterine fetal deaths, and birth of non-viable piglets with apparent signs of goiter. Moreover, thyroid hypofunction leads to decreased general and lipoid metabolism in pigs, young animals in particular. Feed is the source of iodine for pigs. Yet, due to intensive growing practices the primary place in pig nutrition is occupied by concentrated feed with as a rule low content of this microelement. In addition, a number of other factors affect iodine levels in organism. Iodine digestibility is particularly hindered by glucosinolates and cyanogenic glycosides, nitrates, nitrites, perchlorates, residue of some pesticides. Iodine absorption in gastrointestinal tract is slowed down by fluorine and sulfur. Pigs may receive enough iodine with additional feed containing inorganic (КІ, NaІ) and organic (iodates) compounds. For this purpose industrial farms tend to use premixtures and mineral additives containing iodine and other macro- and microelements. However, said forms of iodine-containing preparations are often unstable or even aggressive in combination with other components of additives, namely vitamins. In this connection, we are facing a relevant problem of finding new preparations that in small doses would be stable and compatible with other components of compound feed while solving the problem of microelement nutrition. In humane and veterinary medicine nanomaterials, namely metal aquachelates, are used increasingly more often. There is information as to positive impact that iodine aquacitrate has on animals which needs to be further confirmed by profound research.

Superar la sostenibilidad urbana: una ruta para América Latina
Authors: Contreras Christian Hernán 
Published: May 2017

Resumen: El presente trabajo de reflexión es un análisis teórico sobre sostenibilidad urbana y ecología política urbana. El desarrollo del artículo indaga sobre cómo la sostenibilidad urbana y la ecología política urbana, asumen la dialéctica naturaleza/urbanismo como elemento central en sus proposiciones y cuales son las diferencias radicales que se conciben desde sus respectivas bases teóricas. Adicionalmente se discute sobre las visiones globales que promueve la sostenibilidad urbana y se proponen planteamientos, desde la ecología política urbana, como una ruta posible para el análisis urbano en América Latina. A manera de conclusión se plantea superar los cuerpos teóricos de la sostenibilidad urbana de corte global, por enfoques que asuman los procesos naturaleza/urbanismo como construcciones co-constituidas, en entornos complejos y dinámicos, donde prevalezcan análisis multi-escalares (local, nacional, regional y global) de los procesos sociales, económicos, políticos y ecológicos de los actuales paisajes urbanos latinoamericanos.
Social networking addiction, attachment style, and validation of the Italian version of the Bergen Social Media Addiction Scale
Authors: Monacis Lucia , de Palo Valeria , Griffiths Mark D. , Sinatra Maria 
Published: May 2017

Aim
Research into social networking addiction has greatly increased over the last decade. However, the number of validated instruments assessing addiction to social networking sites (SNSs) remains few, and none have been validated in the Italian language. Consequently, this study tested the psychometric properties of the Italian version of the Bergen Social Media Addiction Scale (BSMAS), as well as providing empirical data concerning the relationship between attachment styles and SNS addiction.

Methods
A total of 769 participants were recruited to this study. Confirmatory factor analysis (CFA) and multigroup analyses were applied to assess construct validity of the Italian version of the BSMAS. Reliability analyses comprised the average variance extracted, the standard error of measurement, and the factor determinacy coefficient.

Results
Indices obtained from the CFA showed the Italian version of the BSMAS to have an excellent fit of the model to the data, thus confirming the single-factor structure of the instrument. Measurement invariance was established at configural, metric, and strict invariances across age groups, and at configural and metric levels across gender groups. Internal consistency was supported by several indicators. In addition, the theoretical associations between SNS addiction and attachment styles were generally supported.

Conclusion
This study provides evidence that the Italian version of the BSMAS is a psychometrically robust tool that can be used in future Italian research into social networking addiction.
Which dimensions of impulsivity are related to problematic practice of physical exercise?
Authors: Kotbagi Gayatri , Morvan Yannick , Romo Lucia , Kern Laurence 
Published: May 2017

Background and aims
Problematic practice of physical exercise (PPPE) has been suggested to be a behavioral addiction. Impulsivity represents a core dimension of behavioral addictions. However, little is known about impulsivity facets in PPPE. The aim of this study was to investigate the role of impulsivity facets in PPPE.

Methods
A total of 684 students (between 18 and 25 years) took part in this study and filled up a battery of questionnaire, which consisted of following measures – Global Physical Activity Questionnaire, Exercise Dependence Scale – Revised, and the UPPS Impulsive Behavior Scale. Multiple regression analyses were utilized to investigate the predictive role of each impulsivity facet in PPPE.

Results
Age, the total level of physical activity per day, sex (male), negative urgency, and sensation seeking were found to be significant predictors of PPPE. A categorical analysis of PPPE revealed that negative urgency, positive urgency, and sensation seeking were significantly higher in the dependent category of PPPE.

Discussion and conclusions
Associations to negative urgency and sensation seeking might indicate that PPPE serves to regulate or alleviate negative affect or aversive emotional states. Thus, PPPE could be conceptualized as a short-term coping strategy dedicated to relieving negative affective states, like other maladaptive behaviors such as binge eating, binge drinking, or compulsive buying.

Abstract

Background
Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, is a rare malignant neoplasm of the olfactory mucosa. Despite surgical resection combined with radiotherapy and adjuvant chemotherapy, ENB often relapses with rapid progression. Current multimodality, nontargeted therapy for relapsed ENB is of limited clinical benefit.

Materials and Methods
We queried whether comprehensive genomic profiling (CGP) of relapsed or refractory ENB can uncover genomic alterations (GA) that could identify potential targeted therapies for these patients. CGP was performed on formalin-fixed, paraffin-embedded sections from 41 consecutive clinical cases of ENBs using a hybrid-capture, adaptor ligation based next-generation sequencing assay to a mean coverage depth of 593X. The results were analyzed for base substitutions, insertions and deletions, select rearrangements, and copy number changes (amplifications and homozygous deletions).

Results
Clinically relevant GA (CRGA) were defined as GA linked to drugs on the market or under evaluation in clinical trials. A total of 28 ENBs harbored GA, with a mean of 1.5 GA per sample. Approximately half of the ENBs (21, 51%) featured at least one CRGA, with an average of 1 CRGA per sample. The most commonly altered gene was TP53 (17%), with GA in PIK3CA, NF1, CDKN2A, and CDKN2C occurring in 7% of samples.

Conclusion
We report comprehensive genomic profiles for 41 ENB tumors. CGP revealed potential new therapeutic targets, including targetable GA in the mTOR, CDK and growth factor signaling pathways, highlighting the clinical value of genomic profiling in ENB.

Angelman Syndrome: Identification and Management
Authors: Bonello Daniela , Camilleri Francesca , Calleja-Agius Jean 
Published: May 2017

AbstractAngelman syndrome (AS) is a neurobehavioral and genetically determined condition, which affects approximately 1 in 15,000 individuals. It is caused by various genetic mutations and deletions of the maternally-inherited UBE3A gene, on the 15q11-13 chromosomal region. The UBE3A gene, which encodes E3 ubiquitin ligase, shows tissue-specific imprinting, being expressed entirely from the maternal allele.The diagnosis of AS is confirmed either by methylation test or by mutation analysis. A more severe clinical picture is linked with the deletion phenotype.Patients with AS have a behavioral and motor pattern defined as “happy puppet” because it is characterized by puppet-like ataxic jerky movements; a happy, sociable disposition; and paroxysms of laughter.There is currently no cure for AS, and management is mainly symptomatic. Novel therapeutic options are directed toward the possibility of activating the silenced paternal copy of the UBE3A gene.
Use of Placental/Umbilical Blood Sampling for Neonatal Admission Blood Cultures: Benefits, Challenges, and Strategies for Implementation
Authors: Moore Shannon P. , Newberry Desi M. , Jnah Amy J. 
Published: May 2017

AbstractPlacental blood remains an underused resource for early neonatal care despite ample evidence that placental blood provides the same clinical decision making information without the need for painful, invasive blood sampling procedures. Potential benefits of placental/umbilical blood sampling (PUBS) for neonatal admission labs include decreases in pain reactivity, rates of anemia, need for blood transfusions, use of vasopressors, and rates of intraventricular hemorrhage. Here, we present a unique case study of a critically ill infant with contradictory blood culture results from PUBS and direct infant sampling. A negative admission direct sample blood culture result compared with a positive admission PUBS blood culture result suggests that infection may have been missed in the direct infant sample. Relevant placental embryology and circulation is also described, as well as the benefits of PUBS for neonatal admission labs (with focus on the blood culture), challenges associated with PUBS practice, and strategies for implementation of PUBS.

Purpose:In this article, the authors discuss best strategies for recruitment and retention among faculty of color, international faculty, and women to diversify rehabilitation counselor education faculty.Method:Based on a comprehensive literature review, we have provided the reader with a brief review of the status of faculty of color, international faculty, and women in academia, issues in recruitment and retention, and strategies that may be beneficial in diversifying rehabilitation counselor education faculty.Results:Researchers in higher education have shown that a diverse faculty is not only beneficial to academia, but to communities as well. The authors have provided recruitment and retention strategies that have been used in other disciplines. Coupled with a sincere commitment by university administrators, faculty, students, and communities, these strategies may be beneficial in increasing diversity among the faculty ranks in rehabilitation counselor education programs.Conclusion:In order to increase diversity in our training and education programs, it is imperative that recruitment and retention plans are created and implemented. Various recruitment and retention strategies were discussed in this article that have been shown to be effective in other disciplines. Future research should explore the presence and use of recruitment and retention plans in rehabilitation counselor education programs. In addition, qualitative research is warranted to explore the experiences of faculty of color, international faculty, and women.
Working With Business: Counselor Expectations, Actions, and Challenges
Authors: McDonnall Michele C. 
Published: May 2017

Purpose:The purpose of this study was to (a) explore state-federal vocational rehabilitation (VR) agency expectations for counselor engagement with business, (b) determine what VR counselors are actually doing in terms of interacting with businesses, and © identify challenges VR counselors experience to working with business.Method:A mixed-methods approach, including both quantitative data from surveys and qualitative data from interviews, was used. Surveys were conducted with 47 VR agency administrators and 121 counselors, and interviews were conducted with 6 administrators and 19 counselors.Results:Almost all VR agencies had a clear expectation that counselors will engage with business, but the specific expectations varied by agency. Counselors spend approximately 20% of their time interacting with businesses, and most counselors reported providing one or more service to businesses on a regular basis. Challenges experienced by counselors were lack of time, lack of comfort, and lack of preparation to engage with business.Conclusion:Given the current expectations for business engagement and the increased importance of business engagement with the passage of the Workforce Innovation and Opportunity Act (2015), it is vital that rehabilitation counseling master’s programs increase their focus on working with business.
