Published: November 2021

Introduction: Trinitrobenzenesulfonic acid (TNBS)-induced experimental colitis in animals is a commonly used model of inflammatory bowel disease (IBD). Eugenol (Eug) is a natural phenolic compound possessing promising antioxidant and anti-inflammatory therapeutic properties.

Aim: The present study investigated the effects of Eug in a TNBS-induced rat colitis model using criteria for histopathological evaluation of the colonic damage.

Materials and methods: Male Wistar rats were divided into 6 experimental groups, each of 10 rats: Control, TNBS, TNBS+Eug1, TNBS+Eug5, TNBS+Eug25, and TNBS+Eug125 group. Eug or the solvent (sunflower oil) was applied orally using an orogastric cannula. The control group and TNBS group were treated only with sunflower oil. Eug groups were treated with corresponding doses of Eug (1, 5, 25 and 125 mg/kg) dissolved in sunflower oil. Colitis was induced by the application of TNBS in the colon. The animal treatment began 6 days before the colitis induction and continued for 8 days after it. At the end of the experiment, colitis severity was evaluated histopathologically regarding epithelium injury, inflammatory cell infiltration, and formation of granulation tissue.

Results: In all TNBS+Eug groups, the formation of granulation tissue was enhanced compared to TNBS. In group TNBS+Eug125 the difference was significant compared to the control group (p < 0.05). No significant improvement regarding the scores of epithelium injury and inflammatory cell infiltration was observed in Eug groups compared to TNBS group.

Conclusion: Eug did not improve the signs of TNBS-induced epithelial injury and inflammatory cell infiltration, but stimulated the formation of granulation tissue which might be considered as a sign of healing.

Published: November 2021

Background: Conventional cytogenetic is one of the most important diagnostic tools for predicting the overall survival of the patients. Molecular genetics in acute myeloid leukemia (AML) has provided insights into the molecular mechanism of leukemogenesis. In this study we aimed to investigate the impact of cytogenetic and molecular methods on the survival of patients with de novo established AML in order to achieve a useful marker or test in the process of predicting the disease course.

Material and methods: Eighty newly diagnosed AML patients who were treatment naive entered the study. Cytogenetic and molecular studies such as, the conventional karyotyping, sequencing and reverse transcriptase real time quantitative PCR (RT-qPCR) were included. Overall survival was calculated by Kaplan-Maier technique and the data were analyzed by SPSS.V.19.

Results: Among 80 patients, 36 (45%) were female and 44 (55%) were male patients. Patients’ median age was 29 years, ranging from 1 to 76 years. The mean overall survival was 19 months (95% CI: 1523 months). The 1-year AML survival rate was 61%. There were significant differences in overall survival between the NPM1-mutated groups compared to the patients without any mutations (19% versus 61%) (p < 0.032).

Conclusion: This study makes a significant contribution in assessing the prognostic value of cytogenetic and molecular markers. This study showed the heterogeneity of de novo AML that involved various factors and prevalence of distinct cytogenetic subgroups. Our data in comparison with other population-based studies, confirmed a differential distribution of cytogenetic and molecular classification indicating geographic heterogeneity.

India remains as a top supplier of value-added seafoods to the global markets. Cochin is one of the leading fishing ports in India contributing to country’s major seafood export. As part of risk assessment, we analyzed the prevalence of multi-drug resistant Vibrio parahaemolyticus; seafood borne gastroenteritis-causing pathogen, in shellfishes collected from major fish markets in Cochin. This bacterial species was initially isolated on thiosulfate-citrate-bile salts-sucrose agar and HiCrome™ Vibrio agar, further confirmed by detection of V. parahaemolyticus species-specific toxR gene and by 16S r RNA sequencing. A total of 113 confirmed V. parahaemolyticus were recovered. Almost all the strains exhibited resistance towards three or more antibiotics (multiple-drug resistant) and harbored virulence related exoenzymes especially hemolysin (Kanagawa phenomenon); which is indeed a matter of concern. The multiple antibiotic resistance (MAR) index of the isolates ranged from 0.21 to 0.57. Furthermore, our results also indicate a substantial increase in the incidence of the pathogen in seafood from the area compared to previous years. This may pose a risk to the local and international consumers of the seafood. Practicing complete hygiene and adequate cooking is strongly recommended. Regular monitoring of aquaculture areas and fish markets is urged to reduce dissemination of pathogenic V. parahaemolyticus in seafood and to prevent fatal cases of human infection induced by this species in the country.

Published: November 2021

The role of reactive oxygen species (ROS) during oocyte in vitro maturation (IVM) is still controversial. Although an increase in ROS production may cause deleterious effects in cells, these reactive species may also act as signaling molecules influencing different cell functions. The aim of this study was to examine the effect of varying endogenous ROS levels during IVM on the process of bovine oocyte maturation. To do so, different enzymatic antioxidant (catalase, or superoxide dismutase + catalase, or diphenyl iodonium) or pro-oxidant systems (xanthine + xanthine oxidase, or xanthine + xanthine oxidase + catalase) were added to the culture medium. ROS levels were determined by 2′,7′-dichlorodihydrofluorescein diacetate stain, nuclear maturation was evaluated by the presence of the metaphase II chromosome configuration at 22h of IVM and cleavage rate was recorded 48h post- in vitro fertilization. ROS levels were only significantly increased (P<0.05) by the O2
.- generating system (xanthine + xanthine oxidase + catalase), but meiotic maturation rates were significantly lower (P<0.05) in all the evaluated systems compared with the control, except for the diphenyl iodonium group. However, this last group presented a significantly lower (P<0.05) cleavage rate in comparison to the control group. These results indicate that ROS would play an essential role during oocyte maturation, since its increase or decrease beyond a physiological level significantly reduced nuclear or cytoplasmic maturation rates in bovine oocytes.

The large intestine epithelium plays an important role in water absorption and participates in fluid, acid-base and electrolyte balance, and the removal of waste products. The large intestine is rich in microorganism-presented enzyme activity. Apart from energy supply, the colon also participates in the synthesis of trophic factors and the modulation of the immune system and the systemic inflammatory response. The current study investigated the effects of dietary HMB administration to pregnant sows on the postnatal development of the colon in their offspring, at weaning. From the 70th to the 90th day of gestation, sows received either a basal diet (n = 12) or the basal diet supplemented with HMB (n = 12) at a dose of 0.2 g/kg of body weight/day. Maternal HMB treatment increased serum IgG and glucose concentrations and decreased serum urea concentration in the piglets. Basal histomorphometric analysis of offspring large intestines showed that prenatal HMB treatment led to a reduction in the thickness of the mucosa, submucosa and both types of myenterons, as well as reduced crypt thickness. The immunoreaction performed to mark T0 lymphocytes and total T lymphocytes in the colon wall showed that prenatal HMB treatment decreased the number of both types of lymphocytes. Greater expression for cadherin was found in the colon of piglets delivered by the HMB-treated sows. The expression of both tight junction proteins (occludin and claudin-3), as well as that of leptin, was stronger in the HMB-treated group. Vasoactive intestinal peptide (VIP) expression was stronger in the submucosal plexuses in the HMB maternal treated piglets, while no changes were observed in the myenteric plexuses. The results obtained indicate that the administration of HMB to pregnant sows significantly influenced the expression of leptin, VIP and some proteins of the intestinal barrier in their offspring, with less influence on large intestine basal morphology.

Published: November 2021

The aim of the study was to determine the effect of two proportions of arginine (95% and 105%) relative to lysine (Lys), where Lys content in the diet is in accordance with NRC (1994) recommendations or 10% higher, on the metabolism, antioxidant status, and growth performance of turkeys. The experiment had a 2x2 factorial design with two levels of Lys and Arg. The diets with a low level of Lys were according to the NRC (1994) requirements. In the diets with a high level of Lys, the content of Lys was increased by 10% relative to the low level Lys. The two Arg levels in the experimental diets were determined so as to provide 95% and 105% Arg relative to the content of dietary Lys. An increase in the amount of Lys in the diet of turkeys by 10% relative to NRC nutritional recommendations (1994) was not shown to improve growth performance, but had beneficial effects on the metabolism and antioxidant status of the birds, as evidenced by the improvement of hepatic indices (reduction of AST and ALT activity at 9th week of life) and renal indices (reduction of UREA at 9th week of life and reduction of TP and increase level of ALB levels at 16th week of life), as well as an increase in the level of glutathione with strong antioxidant properties at 16th week of life. In comparison to the lower level of Arg in the diet, an increase in the amount of this amino acid to 105% Lys did not improve growth performance, metabolism, or antioxidant status. An Arg level of 95% Lys can be used in a diet for turkeys containing 10% more Lys than the level recommended by the NRC (1994).
The importance of nutrition in alleviating high stocking density stress in poultry - A Review
Authors: Gül Esra Tuğçe , Yildiz Alpönder , Olgun Osman
Published: November 2021

In recent decades, the number of birds reared per unit area has dramatically spiked to increase profitability in egg and meat production. However, nowadays, the increase in sensitivity to animal welfare and consumer demands brings along with it a raised interest in stocking density. Stocking density is defined either as the number of animals or body weight per unit area or as the area per animal. High stocking density, which is a stress factor, can be defined as an increase in the number of animals per unit area or a decrease in the area per animal. Stress caused by high stocking density negatively affects the bird’s physiology and performance as well as the quality of the product obtained. The ideal stocking density should be 9 laying hens, 35 kilograms for broilers, and 45 quails per square metre. Otherwise, one will observe stress indicators in birds reared in more than the recommended stocking density per unit area and, consequently, a decrease in bird growth, egg production, feed efficiency, and egg or meat quality. Apart from increasing the concentrations of amino acids such as lysine, methionine, tryptophan and arginine, minerals such as selenium and chromium, and vitamins such as C and E in the diet, the addition of additives such as probiotics, humates, phytophenol compounds, and propolis is also effective in reducing or eliminating these negative effects caused by high stocking density. As a result, regulations in the nutrition of animals are effective in reducing/preventing such negative effects, thus improving animal welfare and ensuring the maintenance of optimum yield.
β-glucan as a promising food additive and immunostimulant in aquaculture industry
Authors: Khanjani Mohammad Hossein , Sharifinia Moslem , Ghaedi Gholamreza
Published: November 2021

The use of antibiotics in aquatic feed reduces the incidence of disease and enhances growth performance, although it presents harmful effects, such as development of resistant bacteria and accumulation in the natural environment. A variety of immune stimulants including probiotics, prebiotics, synbiotics, phytobiotics, organic acids, nucleotides, antioxidants, microalgae, yeast and enzymes have been used in the aquaculture industry. In recent decades, much attention has been paid to finding a variety of immunostimulants with lower cost which also affect specific and non-specific immunity and improve fish resistance against a wide range of pathogens. These stimulants strengthen the fish’s immune system by increasing the number of phagocytes, lysozyme activity and level of immunoglobulin. The use of immune stimulants as an effective tool to overcome diseases and strengthen the immune system of farmed species, leads to the promotion of cellular and humoral defense mechanisms and increases resistance to infectious diseases. Among these immunostimulants used in aquaculture, β-glucans are of particular importance. Glucans are complex polysaccharide compounds extracted from the cell wall of yeasts and fungi. These compounds can stimulate fish growth, survival, and immune function. Therefore, this review discusses the role and importance of β-glucan as a food additive in aquaculture and examines the impact of these compounds on the growth performance, immunity and biochemical parameters of farmed species.

Published: November 2021

Canine DNA is widely used in forensic investigations, particularly in cases of dog attacks on humans. Nowadays, STR markers are employed worldwide in forensic laboratories to test human and animal genotypes. In the study we analysed the effectiveness of 18 STR panel as previously recommended by ISAG and the same panel with three additional markers – 21 STR, which has been recommended by ISAG as the core panel for dog identification since 2016. We calculated the PD, PID for these sets of panels and estimated RMP based on the DNA profile obtained during an investigation of a woman bitten by a dog. The high combined CPD value for 18 and 21 STRs showed values close to 1.0. The CPID value for theses panels was 5.2 × 10−10 to 6.4 × 10−14. Statistical analysis estimated the random DNA match, in the case of the woman bitten by a dog, with a probability of 4.3×1019 and 2.8×1022, using 18 and 21 STR panels respectively, and that the canine DNA profile from the crime scene originated from the suspected dog and not from another random dog. Our results show that both STR panels can be used effectively for individual identification and forensic casework.

Modifying the chemical composition of a diet can be a good strategy for reducing methane emission in the rumen. However, this strategy can have adverse effects on the ruminal microbial flora. The aim of our study was to reduce methane without disturbing ruminal function by stimulating the growth and propagation of methanotrophs. In this study, we randomly divided twenty multiparous Holstein dairy cows into 4 groups in a 2×2 factorial design with two forage levels (40% and 60%) and two nitrate supplementation levels (3.5% and zero). We examined the effect of experimental diets on cow performance, ruminal fermentation, blood metabolites and changes of ruminal microbial flora throughout the experimental period (45-day). Additionally, in vitro methane emission was evaluated. Animals fed diet with 60% forage had greater dry matter intake (DMI) and milk fat content, but lower lactose and milk urea content compared with those fed 40% forage diet. Moreover, nitrate supplementation had no significant effect on DMI and milk yield. Furthermore, the interactions showed that nitrate reduces DMI and milk fat independently of forage levels. Our findings showed that nitrate can increase ammonia concentration, pH, nitrite, and acetate while reducing the total volatile fatty acids concentration, propionate, and butyrate in the rumen. With increasing nitrate, methane emission was considerably decreased possibly due to the stimulated growth of Fibrobacteria, Proteobacteria, type II Methanotrophs, and Methanoperedense nitroreducens, especially with high forage level. Overall, nitrate supplementation could potentially increase methane oxidizing microorganisms without adversely affecting cattle performance.
Correlation of Rheological Properties of Ferrofluid-Based Magnetorheological Fluids Using Some Dimensionless Numbers Defined in Magnetorheology

Published: November 2021

In this paper we investigated from rheological point of view some samples of ferrofluid-based magnetorheological fluids (FF-MRFs) with different volumic fractions of Fe microparticles, but with the same ferrofluid used as carrier liquid. We correlated the dimensionless flow curves, measured at different values of the magnetic field induction, using either Mason number or Casson number. It has been shown that in this approach, data sets measured under different conditions collapse on a single curve. This master curve is useful for controlling the concentration of Fe particles, so that the magnetic and magnetorheological properties of FF-MRF to be adapted to obtain high-performance applications.
Scattering of Fermions by a Magnetic Dipole Field
Authors: Hategan Sergiu , Crucean Cosmin
Published: November 2021

In this paper we study the problem of fermions scattering by the field of a magnetic dipole in Minkowski space-time. The amplitude and differential cross section for scattering of massive fermions are obtained using the exact solution of the Dirac equation written in the helicity basis. We found that the most probable transitions are those that scatter the fermions perpendicular to the direction of the magnetic field and we consider only the transverse momenta in our analysis. The differential cross section behavior in terms of scattering angle and energy is graphically analysed and we perform a comparative study with the Coulomb scattering.
The Development of Organic Agriculture in Serbia and Worldwide
Authors: Golijan Jelena , Sečanski Mile
Published: November 2021

Organic agriculture is a food production system that sustains the health of people, soils and ecosystems with no adverse consequences, combining tradition, innovation and science. The development of such type of agricultural production, from its beginnings to the present day, has encompassed a number of specific stages both in Serbia and worldwide. Accordingly, the purpose of this survey study is to present the developmental course of organic agricultural production in Serbia and worldwide. The paper also summarises the state of organic plant production across different regions of Serbia, arguing that the Serbian organic production has been increasing since the 1990s. Following the political changes in Serbia in 2000, foreign donations, investments and organisations have significantly enhanced the country’s organic production sector as a whole. The largest number of organic producers (1/3) and the largest areas devoted to organic farming are concentrated in Vojvodina.

Published: November 2021

Allelopathic effects of different plant allelochemicals have become the focus of studies that aim to determine new pesticidal compounds. Plant extracts with different chemical compositions can be obtained using different methods of extraction, whereas studies dealing with allelopathic properties use biotests to obtain fast and precise results. Such studies were undertaken after noticing the allelopathic effects of industrial hemp (Cannabis sativa L.) on the surrounding crops. Trials that involve the application of hemp extracts obtained by different methods resulted in determining the hemp allelopathic effects on Stellaria media (L.)Scop., Beta vulgaris ssp. vulgaris var. vulgaris, Lupinus albus L., corn (Zea mays L.), Cyperus rotundus L., Matricaria recutita L., Lepidium sativum L., lettuce (Lactuca sativa L.), rapeseed (Brassica napus L.), wheat (Triticum aestivum L.), rye (Secale cereal M. Bieb.), Ambrosia artemisiifolia L., Chenopodium album L., and Sorghum halepense L..

Published: November 2021

The objective of the present paper was to isolate microorganisms (Pseudomonas sp., Bacillus sp. and Azotobacter sp.) from the rhizospheric soil of rosemary (Rosmarinus officinalis L.) and investigate their biostimulatory (plant growth-promoting – PGP) and biocontrol potential. The bacteria isolated from the rhizosphere of rosemary included 15 bacteria of the genus Pseudomonas, 20 of the genus Bacillus, and 11 of the genus Azotobacter. Based on the morphological characteristics of colonies and cells, representative isolates of each genus were chosen (marked as Pseudomonas sp. P42, P43, P44; for Bacillus isolates B83, B84, B85, B92, B93; and for Azotobacter isolates A15 and A16) for different physiological and biochemical examination. The study included in vitro screening of the bacterial isolates for their PGP and biocontrol properties. Pseudomonas isolates showed the ability to live at low temperature (10ºC) and high pH (9), and to use different sources of carbon. All Pseudomonas isolates produced lipase, siderophore, hydrogen cyanide, and utilized organic and inorganic phosphorus, while only isolate P42 produced amylase, pectinase and cellulase. Only Bacillus isolates could grow at 45 ºC (all Bacillus isolates), pH 5 (isolates B83), and on a medium containing NaCl 5 and 7% (all isolates). Isolates denoted as B83 and B93 produced lipase, amylase, and pectinase. All isolates had the ability to solubilize phosphate, produce siderophores (except B85) and hydrogen cyanide, while only two isolates (B84 and B85) produced IAA. Azotobacter isolates had the optimal growth at 37ºC and minimal growth on a medium with pH 6 and 9. All Azotobacter isolates used all carbohydrates as a source of carbon and produced lipase, amylase, and hydrogen cyanide. The best result in suppressing the growth of pathogenic fungi Fusarium oxysporum was achieved by using isolate B92. Application of isolate B83 led to the greatest growth suppression of Sclerotinium sclerotiorum.

The purpose of this study is to assess the repellent activity of lemongrass (Cymbopogon citratus) essential oil (EO), grown in Serbia under greenhouse conditions, against four prevalent stored product pests: Plodia interpunctella (larvae), Sitophilus oryzae, Acanthoscelides obtectus and Tribolium castaneum (adults). The lemongrass EO repellency was tested using filter paper in Petri dishes and a Y-tube olfactometer. According to the repellency index (RI), the lemongrass EO repellency was divided into 5 classes. Prior to biotesting, the chemical characterization of lemongrass EO was performed and the following main compounds were detected: myrcene (31.0%), geranial (30.0%), and neral (23.6%). The C. citratus EO considered was found to exhibit the Class III repellent activity against P. interpunctella larvae only at the highest concentration (namely 0.5%). This is the very first report on the C. citratus EO repellent activity against this pest. The lemongrass EO examined showed strong repellency (Class IV) against S. oryzae (0.2% and 0.5% of EO), A. obtectus (0.1% and 0.2%), and T. castaneum (0.05-0.1%). Moreover, higher lemongrass EO concentrations (0.5%) were found to exhibit extreme repellency (Class V) against A. obtectus and T. castaneum. The results obtained were confirmed in the bioassays performed, indicating the great potential of lemongrass EO as a bio-repellent when applied in higher concentrations to all the insects considered, regardless of the exposure period.
“The Story is My Life”: Bridging Symbol to Self in a Novel Creative and Reflective Writing Task
Authors: Lang Jacob , Cupchik Gerald C.
Published: November 2021

This article describes the development and testing of a novel creative and reflective writing task. Following the rationale of sand-tray and play therapies, participants were asked to meaningfully incorporate four objects from a randomly generated matrix of options into a creative short story. They then composed a second story that incorporated four possessions from home associated with important memories. Afterwards, participants produced interpretive statements or reflections on what the stories meant to them. An exploratory qualitative study was conducted based on narrative data from 15 young adult participants in Canada. Our goals were to: (a) explore the extent to which object familiarity was associated with qualitative differences in stories and interpretations, and (b) investigate for connections between features of participants’ stories and depth of interpretation. Analysis of creative stories resulted in a scheme of four response categories with ten subcategories. Participants’ interpretations of their own stories were coded based on self-described sources of inspiration, such as critical life episodes or popular media. Results are accompanied with excerpts of participants’ stories and reflections, and percentage comparisons are reported. Findings are presented in dialogue with established interpretive frameworks originating in depth psychology. Manipulation of object familiarity resulted in demonstrable differences at the levels of word length, point of view, narrative forms and features, self-disclosure, and reflection. Use of familiar objects in such a task appears to be a largely untapped resource that shows promise as a route to insight.

Authors: Murillo Adolf , Riaño María Elena , Bautista Alfredo
Published: November 2021

While creativity is a key element of contemporary curriculum frameworks around the world, it is still insufficiently fostered in formal education settings. This study analyzes a project for collaborative musical creativity, entitled The Sonorous Paella. Participants (N = 12) were eight Year 4 secondary students, two professional musicians, an artist-in-residence, and a music teacher. Drawing on a graphic musical score, the participants worked together for 1.5 months to produce a group composition and performance. They were provided with various sound producers (instruments, everyday objects, technological devices) and were encouraged to flexibly utilize the physical space to maximize collaborative participation. Field notes and pictures taken during working sessions and rehearsals, audio recordings from the final concert, and individual interviews with all participants were qualitatively analyzed. In response to the three study objectives, we conclude that: (1) the design of this collaborative project was consistent with current research-based creativity discourses; (2) drawing on the quality and originality of the final concert, the project fostered the musical creativity of the group; and (3) participants’ perceptions of and opinions about their creativity learning processes were unanimously positive. Our final aim is to inspire music teachers in designing curriculum units that foster collaborative musical creativity.
Spreading one’s Wings, Milestones, Deus ex Machina: Self-creation as a Process of Changing Your Life with the Examples of Narrations Provided by Women
Authors: Chmielińska Aleksandra , Modrzejewska-Świgulska Monika
Published: November 2021

This paper presents narrative-biographic research conducted with participation of women who declare that they have introduced important changes into their lives. The qualitative data was collected using narrative interviews as well as a tool to examine changes in the biographic perspective; namely, Line of life. In the presented paper, the authors reconstructed biographical self-creation, meaning the ways of life in which important changes are a central category of a story about life. The authors reconstruct three different ways of narrators’ lives – “spreading one’s wings,” “milestones,” “deus ex machina,” and a case study that describes the process of self-creation and introduction of important changes into a life in more detail.
Automated Monsters of Vengeance: Comparing Goddesses in Ancient Greece and Hindu India
Authors: Nuckolls Charles W.
Published: November 2021

Monsters that act “automatically,” without thought or conscious awareness, constitute a category whose primary exemplar in American culture is the zombie. However, automaticity can be found in other realizations of the monstrous, including in ancient Greece and contemporary India. This paper compares the two. In Greece, the beings known as Eryines hunt and attack people who are guilty of crimes against members of their own kin group. One of the best examples is Orestes, whom the Erinyes pursue relentlessly because he killed his own mother, Clytemnestra. On the southeastern coast of India, among members of the Jalari fishing caste, there is a spirit called Sati Polalmma, who, like the Erinyes, attacks those who have broken oaths made to kin, especially oaths that concern sexual fidelity. The Erinyes and Sati Polamma are chthonic beings, associated with the earth, and are said to predate the patriarchal order of male deities. The paper explores automatic action as a characteristic of one category of the monstrous.
Monsters, Disaster, and Organic Balance: Digesting History Through Oral Traditions
Authors: Veyrié Thierry
Published: November 2021

This paper examines “Coyote, Whirlwind, and Ravine,” a long tale told in the Northern Paiute language by McDermitt storyteller Pete Snapp and recorded by folklorist Sven Liljeblad in the early 1960’s. It weaves in traditional episodes of western Numic folklore to narrate the history of the Fort McDermitt Paiute-Shoshone community as witnessed by an elder born shortly after the beginning of the colonization of this area of the Northwestern Great Basin in the western United States. This paper explores how the bodies of certain characters who emanate from landscape, mainly monsters, are tools for the narrative expression of social change, for the telling of history, and the expression of Indigenous spiritual frameworks. It places the experience of the Indigenous social body, embodied by Coyote, through the grinds of the ultra-material Ravine and confronts it to ethereal nefarious powers. Poetics of materiality applied to the body of Coyote operate a structural transformation. Mythical turmoil expresses social experiences and change in the colonial context, but also makes manifest the transformation of the social body that result in the contemporary form of the Fort McDermitt Paiute-Shoshone community.
“With All The Ghosts that Haunt the Park...”: Haunted Recreation in Brent (Ontario)
Authors: Puppe Ian
Published: November 2021

When I first visited Brent, the defunct logging village, now campgrounds in the northern reaches of Algonquin Provincial Park I went searching for ghost stories. Often described as a “ghost town,” Brent has been occupied since the earliest days of logging in the Ottawa River/Kiji Sibi Valley and holds an important place in the oral history of the Park. The village was a place where many died after violent accidents during the timber rush of the eighteen-hundreds, where Algonquin Anishinaabe Peoples had camped and likely held a village of their own prior to colonization. Brent was once a bustling community, the former site of the Kish-Kaduk Lodge and an important railway stopover during the First World War. Further, Brent was home to the last year round resident of the Park. Mr. Adam Pitts, known to many local cottagers as the “Mayor” passed away in his home in 1998 one year after the railroad tracks were removed by the Canadian National Railway Company and the electricity was shut off. Now his cottage is a ruin some claim to be haunted by the Mayor’s restless ghost. And there are other ghost stories I heard in Brent that haunt the edges of the colonial imagination, stalking unwary travellers as they meander through what they sometimes assume to be “pristine wilderness.” Common patterns of self-apprehension and identity formation associated with tourism and heritage management in Algonquin Park are imbued with nationalist value through a prismatic complex of cultural appropriation, the denial of complicity in colonial violence, and the contingent obfuscation of Indigenous presence and persistence in the area, a process I call haunted recreation. Countering this complex is critical for working past the historical and intergenerational trauma associated with Canadian settler-colonialism and the contemporary inequities of Canadian society.
Growing Appetites and Hungry Subjects: Addicts, the Undead, and the Long Arc of Theory in Western Social Science
Authors: Saris A. Jamie
Published: November 2021

This paper explores the Western philosophical idea of “appetites” through the lens of “addiction.” I begin with a brief ethnographic description of a woman whose subjectivity seems to emerge only in the play of her unmanageable desire for various pharmaceuticals. In other words, she is a self-described “addict.” I then look at the relationships between addicts and the undead, especially vampires and zombies, who are seemingly enslaved to their appetites. This leads me to an analysis of the centrality of what I am calling “recursive need satisfaction” in much of Western (especially Anglophone and Francophone) Social Theory that, I argue, relies on a particular understanding of “appetite” in establishing the political-economic subjectivity that lies at the heart of market-oriented state. This same understanding also pushes this formation in a specific historical direction of increasing growth and organisational and technological complexity. As a globalised Western society in the last few decades has become ever more anxious of its place in the world, its impact on various interdependent systems, and the validity of the grand récits that served as its charter, such growth and complexity have emerged as objects of anxiety, even apocalyptic fear, and the terms “addict” and “addiction” have seemed ever more useful for modelling these concerns. I end with some reflections on how we use both zombies and addicts to think through some of the same issues of unchecked and damaging consumption.

Soccer is the most common team sport in the world. A significant number of players are associated with a large number of injuries. Injuries occur in a variety of contexts regardless of the age or performance level of players. The vast majority of injuries involve soft tissues. Bone injuries are less common, but usually result in long-term exclusion from the game. Three different types of fractures related to soccer are classified as acute types, stress fractures and avulsion. This manuscript outlines the diagnostic procedures and treatments for stress fractures, avulsion fractures and bone cyst. The common feature of the described injuries includes frequent difficulties associated with the correct diagnosis and treatment direction. In therapeutic treatment, the doctor and the patient often have to choose between conservative treatment and surgical treatment, which in many cases is not simple. We suggest that in the event of injuries to soccer players, surgical treatment should be used, shortening the time to return to full sports activity. A very important element of the therapeutic process is proper rehabilitation, which should be individually tailored to the patient in order to optimize the treatment process. Some of the rehabilitation protocols should be permanently incorporated into the warm-up protocols for training. Such a procedure has a preventive effect.

The study aim was to analyze the effects of successive matches on the internal match load, stress tolerance, salivary cortisol concentration and countermovement vertical jump height in twelve youth soccer players (16.6 ± 0.5 yr; 175 ± 8 cm; 65 ± 8 kg) who performed four official matches within a four day-period with a 24-h recovery interval between the matches. The internal match load, monotony index and competitive strain, as well as stress tolerance were examined. Saliva samples were collected and countermovement vertical jump height was assessed 60 min pre and 30 min post each match; delta of salivary cortisol and countermovement vertical jump height for each match were analyzed. Salivary cortisol was analyzed using an enzyme-linked immunosorbent assay. The results of ANOVA with repeated measures showed no differences between matches for the internal match load (p > 0.05). The scores of the monotony index and competitive strain were 4.3 (±2.3) and 8104 (±6795) arbitrary units, respectively. There was no difference for stress tolerance between matches (p > 0.05). Delta values of salivary cortisol were not different among the assessed matches (F(3,33) = 1.397, p = 0.351, η2: 0.09); however, delta of countermovement vertical jump height decreased from match 1 to match 4 (F(3,33) = 8.64, p < 0.001, η2: 0.44). The current findings suggest that participating in four successive matches, with 24-h of recovery in between, may not lead to changes in stress tolerance and salivary cortisol of youth players, but it may induce a decrease in players’ jumping performance after the fourth match.

The aim of the study was to determine the effects of a 6-month training cycle on muscle damage and inflammatory markers in youth male soccer players. Twenty-one soccer players were tested four times: at the beginning (T1) and immediately after the pre-season period (T2), in the middle (T3) and at the end of the competitive period (T4). Muscle damage and inflammatory markers were determined in blood taken 36 hours after the match. Throughout the training cycle significant increases (p < 0.05) of creatine kinase (T1: 254.4 U·L-1; T4: 304.2 U·L-1) and lactate dehydrogenase (T1: 382.8 U·L-1; T4: 453.2 U·L-1) activities were observed. Significant changes (p < 0.05) in platelet count (T1: 210.5·109·L-1; T4: 234.2·109·L-1), percentage of lymphocyte (T1: 39.80%; T4: 42.97%), monocyte (T1: 6.88%; T4: 9.99%) and granulocyte (T1: 53.32%; T4: 47.05%) as well as in granulocyte-to-lymphocyte (T1: 1.41; T4: 1.17) and lymphocyte-to-monocyte (T1: 6.21; T4: 4.46) ratios were noted. The correlation analysis revealed statistically significant relationships (p < 0.05) between: myoglobin and the percentage of leukocyte subpopulations and the granulocyte to lymphocyte ratio; lactate dehydrogenase and the percentage of monocyte; lactate and leukocyte count. In conclusion, the reported muscle damage and inflammatory markers in T3 and T4 indicate the need for fatigue status monitoring in youth soccer players, especially in the competitive period. Moreover granulocyte to lymphocyte and lymphocyte to monocyte ratios proved to be sensitive to fatigue changes and therefore can provide coaches and sport scientists with a broader perspective on the biochemical monitoring of training status in soccer players.

Agility is an important ability for tennis players. To be successful in the rallies, players must perform rapid, multidirectional movements in response to the ball and/or the position of the opponent. For a test to be representative in monitoring agility performance, it should capture a combination of the physical and cognitive agility performance. Considering that literature reports no reliable and valid sport-specific agility test for tennis, the aim of this article was to design and evaluate the measurement properties of a Tennis-specific Agility Test (TAT). To evaluate the TAT, test-retest reliability, concurrent validity, and feasibility were assessed. For reproducibility, a two-way mixed ANOVA was performed. Concurrent validity was assessed using Pearson correlations. A total of 69 tennis players participated in this study of whom 16 competed at the international (22 ± 3.7 years, playing level (Dynamic Rating System): .8 ± .3), 43 at the national (14 ± 1.4 years, playing level: 4.6 ± 1.4), and 10 at the regional level (15 ± 0.8 years, playing level: 4.9 ± 1.1). Test-retest reliability was found to be moderate with an Intra-Class Correlation coefficient (ICC) of .74 (p < .01) and a percentual minimal detectable change (%MDC) of 6.2%. Concurrent validity was found to be moderate by comparison with a recognised agility test, the Spider Drill, which measures only the physical component (.70; p < .01), and by comparison with tennis performance for both boys (r = .67; p < .01) and girls (r = .72; p < .01). The feasibility was high with short time for preparation (five to ten minutes) and time per participant (<5 minutes). In conclusion, the TAT shows promising results for assessing sport-specific agility performance in tennis making it likely to be used in the practical setting.

This study examined changes in match running performance (MRP) in Under-14 soccer players (13.5 ± 0.7 yrs) during a congested match schedule (CMS) (4 matches played within a 5-day period). It also examined the difference in salivary testosterone (sT) concentration, somatic maturation, jumping tests, and Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IR1) between the players selected to play (SLG; group who participated in all matches) and players non-selected to play (NSG). A significant difference was observed for the frequency of decelerations (DEC) across matches (match 4 vs. matches 1, 2 and 3; p = 0.05; partial ƞ2 = 0.20). No difference between matches was observed for total running distance (TRD), high-speed running distance (HSRD), and frequency of accelerations (ACC) (p > 0.05). A wide range for within-player coefficient of variation (CV) values was observed for all MRP variables (range: 10.5 = TRD to 30.6 = HSRD). No difference between SLG and NSG for any of the assessed variables was observed (p > 0.05). The findings suggest that DEC was the most pertinent variable for monitoring changes in MRP during the CMS. In addition, at an elite youth soccer level, the biological maturity and fitness might not influence selection to play.

The assessment of the force-velocity (F-V) profile in athletes may have important applications for training prescription, injury management, and fatigue monitoring. This study aimed to assess whether a novel single kayak stroke test (SKST) is able to provide the F-V relationship variables (maximum force, maximum velocity and maximum power) of competitive kayakers with acceptable reliability and external validity. Six female (age: 20.3 ± 3.7 years) and eight male (age: 20.8 ± 2.4 years) elite kayakers performed the SKST, bench press, bench pull, and short Wingate kayak test. The individual F-V relationships were highly linear [median r (range): left stroke = 0.986 (0.897 - 0.998); right stroke = 0.987 (0.971 - 0.999)]. The reliability of the F-V relationship parameters obtained during the SKST was high (within-session: CV ≤ 4.48% and ICC ≥ 0.93; between-session: CV ≤ 8.06% and ICC ≥ 0.65). The validity of the F-V relationship parameters obtained during the SKST was generally very high for maximum power (r range = 0.825 - 0.975), high for maximum force during both the bench press and the bench pull (r range = 0.751 - 0.831), and high or moderate for maximal velocity during the bench pull (r = 0.770 - 0.829) and the bench press (r = 0.355 - 0.471), respectively. The SKST can be considered a feasible procedure for testing the maximal upper-body muscle mechanical capacities of kayakers.
