Abstract
Myrkos, A, Smilios, I, Zafeiridis, A, Iliopoulos, S, Kokkinou, EM, Douda, H, and Tokmakidis, SP. Effects of work and recovery duration and their ratio on cardiorespiratory and metabolic responses during aerobic interval exercise. J Strength Cond Res 36(8): 2169–2175, 2022—This study examined the effect of work and recovery durations and of work-to-rest ratio (WRR) on total exercise time and oxygen consumption (V̇o
2max), on exercise time above 80, 90, and 95% of V̇o
2max and HRmax, and on blood lactate concentrations during aerobic interval exercise. Twelve men (22.1 ± 1 year) executed, until exhaustion, 4 interval protocols at an intensity corresponding to 100% of maximal aerobic velocity. Two protocols were performed with work bout duration of 120 seconds and recovery durations of 120 (WRR: 1:1) or 60 seconds (WRR: 2:1), and 2 protocols with work bout duration of 60 seconds and recovery durations of 60 (WRR: 1:1) or 30 seconds (WRR: 2:1). When compared at equal exercise time, total V̇o
2 and exercise time at V̇o
2 above 80, 90, and 95% of V̇o
2max were longer (p < 0.05) in 120:120, 120:60 and 60:30 vs. the 60:60 protocol. When analyzed for total exercise time (until exhaustion), total V̇o
2 was higher (p < 0.01) in the 60:60 compared with all other protocols, and in the 120:120 compared with 120:60. Exercise time >95% of V̇o
2max and HRmax was higher (p < 0.05) in the 120:120 vs. the 60:60 protocol; there were no differences among protocols for exercise time >90% of V̇o
2max and HRmax. Blood lactate was lower (p < 0.05) in the 60:60 compared with all other protocols and in the 60:30 vs. the 120:60. In conclusion, when interval exercise protocols are executed at similar effort (until exhaustion), work and recovery durations do not, in general, affect exercise time at high oxygen consumption and HR rates. However, as work duration decreases, a higher work-to-recovery ratio (e.g., 2:1) should be used to achieve and maintain high (>95% of maximum) cardiorespiratory stimulus. Longer work bouts and higher work-to-recovery ratio seem to activate anaerobic glycolysis to a greater extent, as suggested by greater blood lactate concentrations.

Abstract
Robles-Palazón, FJ, Ayala, F, Cejudo, A, De Ste Croix, M, Sainz de Baranda, P, and Santonja, F. Effects of age and maturation on lower extremity range of motion in male youth soccer players. J Strength Cond Res 36(5): 1417–1425, 2022—Restricted joint range of motion (ROM) has been considered as a primary risk factor for some sport-related injuries. Consequently, preparticipation assessment of lower extremity joints ROM could help identify youth soccer players at high risk of injury and to aid in the design of tailored age and maturational specific training interventions. The purpose of this study was to analyze and compare the influence of chronological age and maturational stage on several lower extremity ROM measures, as well as to describe the lower extremity ROM profile using a comprehensive approach in youth soccer players. A total of 286 male youth soccer players' ROM were assessed including passive hip (extension [PHE], adduction with hip flexed 90° [PHADHF90°], flexion with knee flexed [PHFKF] and extended [PHFKE], abduction with hip neutral [PHABD] and flexed 90° [PHABDHF90°], external [PHER] and internal [PHIR] rotation), knee (flexion [PKF]) and ankle (dorsiflexion with knee flexed [ADFKF] and extended [ADFKE]) ROMs. Between-group differences were analyzed using a one-way analysis of variance (ANOVA) and magnitude-based decisions. The results only report statistically significant (p < 0.05; d > 0.5) and clinically relevant differences (>8°) for the PKF ROM between U12 vs. U19, and Pre-PHV vs. Post-PHV groups. Furthermore, approximately 40, 35, and 20% of players displayed restrictions in their PHFKE, PKF, and ADFKF ROM values, respectively. These findings emphasize the necessity of prescribing (across all age groups and periods of growth and maturation) compensatory measures in daily soccer training, and these exercises should be equally applied to both limbs with the aim of improving PHFKE, PKF and ADFKF ROM values.

Accuracy of metabolic cost predictive equations during military load carriage. J Strength Cond Res 36(5): 1297–1303, 2022—To quantify the accuracy of 5 equations to predict the metabolic cost of load carriage under ecologically valid military speed and load combinations. Thirty-nine male serving infantry soldiers completed thirteen 20-minute bouts of overground load carriage comprising 2 speeds (2.5 and 4.8 km·h−1) and 6 carried equipment load combinations (25, 30, 40, 50, 60, and 70 kg), with 22 also completing a bout at 5.5 km·h−1 carrying 40 kg. For each speed-load combination, the metabolic cost was measured using the Douglas bag technique and compared with the metabolic cost predicted from 5 equations; Givoni and Goldman, 1971 (GG), Pandolf et al. 1997 (PAN), Santee et al. 2001 (SAN), American College of Sports Medicine 2013 (ACSM), and the Minimum-Mechanics Model (MMM) by Ludlow and Weyand, 2017. Comparisons between measured and predicted metabolic cost were made using repeated-measures analysis of variance and limits of agreement. All predictive equations, except for PAN, underpredicted the metabolic cost for all speed-load combinations (p < 0.001). The PAN equation accurately predicted metabolic cost for 40 and 50 kg at 4.8 km·h−1 (p > 0.05), underpredicted metabolic cost for all 2.5 km·h−1 speed-load combinations as well as 25 and 30 kg at 4.8 km·h−1, and overpredicted metabolic cost for 60 and 70 kg at 4.8 km·h−1 (p < 0.001). Most equations (GG, SAN, ACSM, and MMM) underpredicted metabolic cost while one (PAN) accurately predicted at moderate loads and speeds, but overpredicted or underpredicted at other speed-load combinations. Our findings indicate that caution should be applied when using these predictive equations to model military load carriage tasks.

El objetivo de este trabajo es determinar los parámetros sanguíneos y la presencia de parásitos en una población salvaje de tortugas deslizantes (Trachemys scripta emolli), durante la estación seca de 2013, en el Refugio de Vida Silvestre Caño Negro, Costa Rica. Utilizando redes, los individuos fueron capturados de diferentes huecos. Se tomó muestras de sangre para determinar los parámetros químicos de esta y el hematocrito, así como los valores morfológicos y las condiciones corporales. Además, se recolectaron muestras de heces y ectoparásitos. El IC del hematocrito 95.0 % fue [14 7091, 18 7356] y no se encontraron diferencias significativas entre los sexos. Los IC del 95 % para los parámetros de la química sanguínea fueron: AST (U/L) [87 6214, 148 929], CK (U/L) [1439.2, 2487.08], AU (umol/L) [68.22, 90.43], GLU (mmol/L) [4.26, 5.47], PHOS [0.46, 0.61], Ca (mmol/L) [1.99, 2.15], PT (g/L) [22.16, 24.44], K (mmol/L) [3.31, 3.83 ] y Na (mmol/L) [127.92, 130.93]. También se obtuvo 21 muestras de heces, de las cuales 10 fueron positivas para parásitos (23.8 % Strongyloides, 14.3 % Ascaridia, 9.5 % Coccidia y 9.5 % Pentastomida). Una sanguijuela de la familia Rhynchobdellidae fue el único ectoparásito encontrado (Placobdella sp.). Ninguno de los individuos estaba enfermo o presentaba abscesos en relación con sus atributos morfológicos. Según los resultados, el manejo empleado no representa un riesgo para esta población de reptiles.

AbstractAn epizootic caused by a new orthobunyavirus called Schmallenberg virus (SBV) was recognised in European ruminants in 2011 and 2012. The re-emergence of the infection was reported in several countries in the subsequent years. Although the main clinical sign of SBV infection is abortion, the impact of SBV in natural cases of abortion in domestic ruminants had not been systematically examined before this study. The aim of the study was to investigate the role of SBV infection and to compare it to the importance of other causes of abortion by examining 537 natural cases of abortion that had occurred between 2011 and 2017 in Hungary. The cause of abortion was determined in 165 (31%) cases. An infectious cause was proved in 88 (16%) cases. SBV infection was found only in a total of four cases (0.8%) using real-time polymerase chain reaction. Three of them proved to be inapparent SBV infection, and one case was attributed to SBV-induced abortion by detecting non-purulent encephalitis and SBV nucleoprotein by immunohistochemistry in a brain tissue sample. According to the results, SBV played a minor role in natural cases of domestic ruminant abortion in Hungary during the 7-year period following the first SBV outbreak in 2011.

AbstractTwo adult barbels (Barbus barbus) with visible skin tumours were subjected to histopathological and molecular examinations. The fish were caught in the River Danube near Budapest. Papillomas were found around their oral cavity, at the operculum and at the pectoral fins, while epidermal hyperplasias were seen on the body surface. Cyprinid herpesvirus 1 (CyHV-1) was detected in the kidney of the specimens by polymerase chain reaction (PCR), and barbel circovirus 1 (BaCV1) was found in all internal organs and in the tissues of the tumours. The whole genome of BaCV1 and three conserved genes from the genome of CyHV-1 were sequenced. Previously, BaCV1 had been reported only once from a mass mortality event among barbel fry. The whole genome sequence of our circovirus shared 99.9% nucleotide identity with that of the formerly reported BaCV1. CyHV-1 is known to infect common carp and coloured carp (Cyprinus carpio), and has been assumed to infect other cyprinid fish species as well. We found the nucleotide sequences of the genes of CyHV-1 to be identical in 98.7% to those of the previous isolates from carp. To the best of our knowledge, this is the first molecular confirmation of the presence of CyHV-1 DNA in cyprinid fish species other than carp.
A pilot study on the pharmacokinetics of a single intramuscular injection of cefquinome in Arabian camel calves

Published: May 2020

AbstractThis study was conducted to evaluate the pharmacokinetics of cefquinome in camel calves after a single intramuscular injection in a dose of 2 mg/kg body weight (kg b. w.). Cefquinome concentrations were measured by ultra-high performance liquid chromatography–mass spectrometry (UPLC-MS/MS). A non-compartmental pharmacokinetic model was used to fit the time–concentration curve and estimate the pharmacokinetic parameters. The peak serum concentration (Cmax) was 28.4 μg/mL at the time of maximum concentration (Tmax) of 25 min. The elimination half-life (t1/2) was 17.4 h. The area under the concentration–time curve (AUC0–∞) was 103.7 μg/ml−1h and the mean residence time (MRT0–∞) was 21.3 h. In comparison with other animal species, the pharmacokinetics of cefquinome in Arabian camel calves showed faster absorption from the site of injection and slower elimination. Since cefquinome, as other beta-lactams, is a time-dependent antimicrobial agent, a single dose of 2 mg/kg b. w. might be sufficient against the most sensitive organisms in camel calves owing to its prolonged elimination phase. However, dose readjustment is required for cases needing concentrations above 2 µg/mL for 12 h or above 1 µg/mL for 24 h.

AbstractA 1-day-old male calf presented with clinical signs of severe progressive abdominal distension. Abdominal radiographic and ultrasonic images revealed several loop-like structures in the small intestine, which were indicative of gas retention. Experimental laparotomy was performed. However, the calf died during surgery. At necropsy, a round, well-circumscribed mass (3 × 3 × 2.5 cm) was found in the jejunal wall, and the jejunal lumen was narrowed. The mass was firm and had white to grey appearance on the cut surface. Histologically, the submucosa and the muscle layer were diffusely thickened due to abundance of neural tissues comprising several fascicles of nerve fibres and large aggregates of ganglion cells. Some ganglion cells contained basophilic Nissl substances in their cytoplasm. Immunohistochemically, these cells were positive for S-100 and synaptophysin. Ultrastructural examination revealed that the neoplastic ganglion cells contained dense core vesicles in the cytoplasm. Based on these findings, the neoplastic lesion was diagnosed as ganglioneuroma in the jejunum.

AbstractThe objective of this study was to examine whether serum iron (Fe) concentration is useful as a prognostic biomarker for cows with acute coliform mastitis (ACM). Our study was composed of determining the reproducibility of serum Fe concentration as a prognostic criterion in cows with ACM (Study 1) and clarifying the sequential changes in serum Fe concentration in cattle that received endotoxin (Study 2). Seventy-seven cows with (n = 47) or without (n = 30) ACM were enrolled in Study 1. The proposed diagnostic cut-off value of serum Fe concentration indicating a poor prognosis of ACM based on the analysis of the receiver operating characteristic curves was < 31.5 µg/dL. Ten young cattle aged 176.8 ± 23.7 days were enrolled in Study 2. Five young cattle received endotoxin (LPS group) and the remaining five received physiological saline (control group). Blood collections were carried out before endotoxin challenge (pre), and 0.5, 1, 2, 4, 8, 12, 24, and 48 h after the challenge. As a result, a significant decrease in serum Fe concentration was not observed until 24 h after endotoxin challenge. Because in cows with clinical ACM it is difficult to know the time course after infection, the alteration in serum Fe concentrations alone may be an insufficient prognostic criterion.

AbstractThe aim of this study was to evaluate the prevalence of uterine prolapse in cows and assess its effects on survival and subsequent fertility. Of 33,450 calving cows considered retrospectively, 216 (0.6%) developed uterine prolapse. A higher prevalence was found in beef cows (n = 57/5,700 cows, 1%) compared to dairy cows (n = 157/27,750 cows, 0.6%). Treatment consisted of cleaning and replacing the uterus with local administration of antibiotics, and applying a harness for uterine containment. The recovery rate was 81.9% (n = 177), similar in dairy (n = 129; 81.1%) and beef (n = 48; 84.2%) cows. Of the 216 cows with uterine prolapse, 18 (8.3%) died before or immediately after treatment; 21 cows (9.7%) were voluntarily culled for economic reasons (low milk yield, low fertility, insufficient weight gain). All recovered dairy cows were artificially inseminated with semen of proven fertility after a voluntary waiting period of 50 days; the beef cows were naturally mated. Among the 172 inseminated/mated cows, 84.7% (n = 150) became pregnant (83.7% dairy cows, 87.5% beef cows), while 15.2% (n = 27) did not conceive. Recurrence of uterine prolapse at subsequent calvings was recorded in one dairy cow. Based upon the data presented here, treated cows with uterine prolapse showed high chances of survival and conception, and a low risk of recurrence.
The first cohomology group of some operator algebras on Hilbert C*-modules

Published: May 2020

Abstract
Let X be a Hilbert C*-module over a C*-algebra B. In this paper we introduce two classes of operator algebras on the Hilbert C*-module X called operator algebras with property and operator algebras with property ℤ, and we study the first (continuous) cohomology group of them with coefficients in various Banach bimodules under several conditions on B and X. Some of our results generalize the previous results. Also we investigate some properties of these classes of operator algebras.
Man Versus Demon:Interconnections between Incantations and Belief Narratives
Authors: Popović Nikolić Danijela 
Published: May 2020

AbstractThe present paper examines the relationship between incantations and belief narratives, two types of oral genres based on human contact with the supernatural. Such contact attests to a dangerous disruption of the boundary between the human and demonic worlds and to the intensive efforts to reinforce it so that participants may return to the space they belong in. For this purpose, various verbal and nonverbal tools are used in belief narratives (gestures, objects, plants, sound or light signals, certain activities – such as walking backwards, placing a cap over the forehead, etc.). In contrast, incantations, an inseparable part of vernacular magical practices, rely solely on verbal communication with impure forces.This paper will analyse the following aspects of interconnection between these oral genres: 1) the display of a genre within a genre – the presence of incantations in belief narratives, e.g., about dispersing hailstorm clouds; 2) the types of verbal communication with the supernatural in belief narratives (swearing, cursing, command, reproach) and their equivalents in incantations; 3) various motifs of protection from demons (counting the uncountable, using bodily fluids; thorn, fire, metal, broom, etc.). The consideration of shared elements in these genres that preserve the relationship with the mythological narrative include elements of the ceremonial context in which incantations are performed. I argue that some of these elements appear also in belief narratives, where they undergo a transformation.
Charms and Wands in John the Lazy: Performance and Beliefs in Argentinean Folk Narrative
Authors: Palleiro María 
Published: May 2020

Abstract“Virtue wands” do appear in Argentinean folk narrative as useful devices used by the hero to achieve his dreams. Using the correct charm and waving his wand, the Argentinean folk hero John the Lazy manages to marry the princess and to live without working. Charms show in this way how to do things with words, pronouncing the proper words in the right situation. In this presentation, I deal with the formulaic use of a magic charm in this Argentinean folktale, collected in fieldwork in 1988. This charm deals with an invocation to the “Wand of virtue” given to the hero by God`s mercy, whose proper use shows the performative force of language. The tension between the absence of effort and the need of working is solved in this tale in a world of dream, in which the real effort is to learn how to use the correct words. Social beliefs in the supernatural are expressed in this tale, in which the wand is a God`s gift that allows the hero to avoid struggling. But the main gift is actually the knowledge of language which permits the hero to make an accurate usage of formulaic discourse, structured in the charm in an epigrammatic way. In this way, I propose a metapragmatic consideration of such charms that, as Urban (1989) says, deal with “speech about speech in speech about action”. In the Argentinean context in which I collected this folktale, the hero is the young son of a rural peasant family, poor and struggling, like the narrator and his audience. The lazy poor boy who marries the princess thanks to the force of the dreams shows how the language is the key both to repair social gaps and to restore collective order.
