Authors: Varlamova A. I. , Arkhipov I. A.
Published: July 2020

The purpose of the research is studying acute toxicity of supramolecular complexes of fenbendazole with different polymers obtained by mechanochemical technology as compared to the substance of the drug when administered to the stomach of white mice.

Materials and methods. The acute toxicity parameters of supramolecular complexes of fenbendazole (SMCF) with different polymers were studied under the “Guide to experimental (preclinical) study of new pharmacological substances” and other rules. The drugs were administered once to the stomach of white mice of both genders with a body weight of 16–18 g at doses of 7,000, 10,000, 15,000 and 20,000 mg/kg by the drug. Each dose was tested on 10 white mice. For 14 days, we observed the general condition and behavior of animals, symptoms of intoxication and possible death. Postmortem examination was performed for the dead animals. Acute toxicity was determined by Litchfield and Wilcoxon (M. D. Belenky, 1963).

Results and discussion. LD50 of the SMCF and the major drug of fenbendazole could not be established due to low toxicity. LD50 of the SMCF administered to the stomach of white mice was 20 000 mg/kg.

Authors: Abdulmagomedov S. Sh. , Bakrieva R. M.
Published: July 2020

The purpose of the research is studying the duration of the chemoprophylactic effect of prolonged solutions of DAC (diminazene aceturate) in combination with a solution of glycerin in bovine pyroplasmidoses.

Materials and methods. 300 cattle were examined at the farms of the Kizilyurt and Kumtorkalinsky Districts of the Republic of Dagestan for tick infection. 45 blood smears were examined. Three groups of animals of 15 animals each were formed according to the principle of analogues. The first control group was administered DAC without glycerol, and the experimental groups were given prolonged solutions of DAC in combination with glycerin 10–12 days after the animals were sent to the pasture with rare solutions of acaricides during the mass tick infection period. The drug was administered intramuscularly at a dose of 4–5 ml per 100 kg of body weight. Animals were observed during the season; in case of any change in general condition, thermometry was performed, and blood smears were examined.

Results and discussion. 5% aqueous solution of DAC in combination with a solution of glycerol provides prophylaxis of pyroplasmidoses in cattle. The chemoprophylactic effect of 5 % aqueous glycerol solution of DAC is kept in the animal body for 25 days. Its 6 times' use ensures the well-being of animals during the season (from April to September).
Trilogía de Dolan: ¿dos o tres?
Authors: Rabain Nicolas
Published: July 2020

A partir de las tres primeras películas dirigidas por Xavier Dolan – Yo maté a mi madre (2009), Los amores imaginarios (2010) y Laurence anyways (2012) –, abordaremos el resurgimiento de los fantasmas matricidas en la pubertad. Si el asesinato del padre constituye uno de los pilares del psicoanálisis, el matricidio remite tanto a fantasmas edípicos como arcaicos. ¿Cómo lograr desprender las investiduras del objeto primario y destinarlas a objetos de substitución en la adolescencia? ¿Sobre quién sostenerse para alejar a una madre de mil caras: dedicada, paraexcitante, primer espejo del ser, amorosa y amada; pero también seductora, intrusiva, abusiva y traicionera, que puede, alternativamente, invadir y abandonar… En Dolan, el odio de la madre es crudo, masivo e incontrolable. Proviene del exceso de lo sexual infantil que viene a obstaculizar el trabajo de la represión. De hecho, no permite ninguna separación y hace de la progenitora una divinidad sobrehumana, todo-poderosa, aterradora, al resistir a la agresividad de su hijo con tanta tenacidad y éxito.Si la trilogía de Dolan bordea toda lógica binaria hetero-normativa –al poner en escena recorridos subjetivos singulares lejos de todo estereotipo–, subsiste de todas formas un punto ciego: la transformación progresiva de los lazos a la imago materna. Odiar a la madre va de la mano con la imposibilidad de abandonarla. El precio: una lucha desenfrenada contra la angustia, la amenaza depresiva e incluso el derrumbe melancólico. Es el hijo, su madre y nadie más. Con esta coyuntura, ¿cómo podría tener lugar la guerra de Tres?
El cine como pasador de lo real
Authors: Laso Eduardo , Michel Fariña Juan Jorge
Published: July 2020

El cine permite dar palabras e imágenes al acontecimiento catastrófico. Ofrece la posibilidad de operar con el real traumático social y en consecuencia simbolizarlo. Tanto el psicoanálisis como el arte emprenden, por vías distintas, esta ardua tarea de hacer pasar lo real a lo simbólico, de inscribir lo imposible. Se trata de dar imágenes, palabras y representaciones a aquello que en principio está ausente, silenciado, rechazado. Para que ese real deje de ser una mortificación hecha herida abierta, instalada como repetición vana. En ese sentido, el cine es pasador de lo real a lo simbólico a través de las imágenes. El presente artículo introduce esta tesis a través de ejemplos de la pintura, la performance y el cine.

FGF10 is differentially expressed in high-grade serous ovarian cancers.
Authors: Mamoor Shahan
Published: July 2020

Ovarian cancer is the most lethal gynecologic cancer (1). Soluble factors are an important part of the tumor microenvironment (2). We sought to identify genes associated with high-grade serous ovarian cancer (HGSC) by comparing global gene expression profiles of normal ovary with that of primary tumors from women diagnosed with HGSC using published microarray data (3, 4). We found significant differential expression of the morphogen fibroblast growth factor 10 (FGF10) in high-grade serous ovarian tumors.
Maltreatment and Emotional Development
Authors: Harms Madeline , Leitzke Brian , Pollak Seth
Published: July 2020

The family environment has strong impacts on children’s emotional development.Although children can adapt to a high degree of variation in the type of input they receive, child maltreatment is a species-atypical experience that disrupts the biological systems that underlie children’s social and emotional development. In this chapter we describe the consequences of maltreatment on children’s emotional development, focusing on alterations in 1) emotion perception, recognition, and attention, 2) emotion expression, 3) regulation of negative emotions and stress, and 4) reward processing. We consider several target mechanisms through which child maltreatment impacts these aspects of emotion processing, including behavioral, physiological, cognitive, and neurobiological, pathways. We also discuss clinical implications of this body of research, including the potential for designing effective interventions aimed at targeting specific emotional biases associated with the experience of maltreatment.
Bayesian Scepsis About SWEPIS: Quantifying the Evidence That Early Induction of Labour Prevents Perinatal Deaths
Authors: Wagenmakers Eric-Jan , Ly Alexander
Published: July 2020

In a recent randomized clinical trial, Wennerholm and colleagues compared induction of labour at 41 weeks with expectant management and induction at 42 weeks. The trial was stopped early, because six perinatal deaths occurred in the expectant management group, whereas none occurred in the induction group. Our Bayesian reanalysis finds that the SWEPIS data indeed support the hypothesis that induction of labour at 41 weeks of pregnancy is associated with a lower rate of stillbirths. However, the degree of this support is moderate at best, and arguably provides insufficient ground for terminating the study. In general, it seems hazardous to terminate clinical studies on the basis of a single P<0.05 result, without converging support of a Bayesian analysis.

Deficits in early auditory information processing contribute to cognitive and psychosocial disability; this has prompted development of interventions that target low-level auditory processing, which may alleviate these disabilities. The frequency following response (FFR) is a constellation of event-related potential and frequency characteristics that reflect the processing of simple acoustic stimuli at the level of the brainstem and ascending portions of the auditory pathway. While FFR is a promising candidate biomarker of response to auditory-based cognitive training interventions, the psychometric properties of FFR in schizophrenia patients have not been studied. Here we assessed the internal consistency characteristics and magnitude of group differences across 18 different FFR parameters to determine which, if any, of these parameters demonstrate adequate internal consistency for use in intervention studies. Electroencephalography from 40 schizophrenia patients and 40 nonpsychiatric comparison subjects was recorded during rapid presentation of an auditory speech stimulus (6,000 trials). Patients showed normal response amplitudes but longer latencies for most FFR peaks and lower signal-to-noise ratios (SNRs) than healthy subjects. Analysis of amplitude and latency estimates of peaks, however, indicated a need for a substantial increase in task length to obtain internal consistency estimates above .80. In contrast, excellent internal consistency (> .95) was shown for FFR sustained responses. Only SNR scores reflecting the FFR sustained response yielded significant group differences and excellent internal consistency, suggesting that this measure is a viable candidate for use in clinical treatment studies. The present study highlights the use of internal consistency estimates of FFR to guide future intervention studies interested in individual differences among patients.
Verbal suggestions about treatment effectiveness do not modulate the effectiveness of a laboratory model of EMDR therapy: Results of two preregistered studies
Authors: Mertens Gaëtan , van Schie Kevin , Lammertink Sophie , Littel Marianne , Engelhard Iris
Published: July 2020

Background: As for many psychotherapies, there is ongoing discussion about the role of specific versus unspecific mechanisms in the effectiveness of Eye-Movement and Desensitization Reprocessing (EMDR) therapy for post-traumatic stress disorder. However, research directly examining the potential role of non-specific mechanisms in EMDR is scarce. Objectives: Here, we address the role of one non-specific factor that is often put forward, namely treatment effectiveness expectations, in a laboratory model of EMDR therapy. Method: In a lab-based study (N = 96) and an online study (N = 173), we gave participants verbal instructions to manipulate their treatment expectations. Instructions emphasized EMDR’s effectiveness or infectiveness. Then, participants were asked to recollect an unpleasant autobiographical memory with or without making eye-movements. Results: In line with previous studies, we found significant reductions of reported vividness and emotionality of negative autobiographical memories. However, this effect was not modulated by manipulated treatment efficacy expectations. It must be noted that manipulation checks indicated that it was difficult to influence treatment effectiveness expectations using verbal suggestions. Conclusions: These findings corroborate the results of two earlier reports, suggesting that the role of treatment expectations in EMDR therapy may be limited.

Learning about wave optics: the effects of combining external visualizations with extreme case reasoning
Authors: Vidak A. , Dananić V. , Mešić V.
Published: July 2020

In this study we investigated whether combining external visualizations with extreme case reasoning may facilitate developing of conceptual understanding about wave optics. For purposes of answering our research question we conducted a pretest-posttest quasi-experiment which included 179 students from a first year introductory physics course at the University of Zagreb, Croatia. Students who were guided through extreme case reasoning in their wave optics seminars significantly outperformed their peers who received conventional teaching treatment. Findings from our study suggest that combining external visualizations with extreme case reasoning facilitates development of visually rich internal representations which are a good basis for performing mental simulations about wave optics phenomena. In addition, it has been also found that many students use the “closer to the source implicates greater effect” p-prim when reasoning about certain relationships, such as the relationship between fringes’ dimension and slits-screen separation.

Canadian Electricity Markets during the COVID-19 Pandemic: An Initial Assessment
Authors: Leach Andrew , Rivers Nic , Shaffer Blake
Published: July 2020

This article examines the effect of the coronavirus disease 2019 (COVID-19) pandemic on electricity markets across select Canadian provinces, using available data. Using high-frequency electricity data, we find electricity demand declined by roughly 10 percent in Ontario and by about 5 percent in Alberta, British Columbia, and New Brunswick. On the supply side, in Alberta we find reductions from some natural gas plants and an increase in net generation from the oil sands region, whereas Ontario sees an increase in net electricity exports. Policy implications include potential rate impacts as a result of fixed charges spread over a smaller rate base, the potential use of electricity data as a real-time economic indicator during the pandemic, and a call to arms to make electricity data across all Canadian provinces more readily available.
The Dangers of Mystifying Artificial Intelligence and Robotics
Authors: Heffernan Teresa
Published: July 2020

From the outset, the field of artificial intelligence (AI) has been steeped in myth and magic, distracting us from the real threat of this technology. Promising miracles, Big Tech has amassed wealth and power by colonizing and privatizing the material world and restructuring labour. From the erosion of democracy, to data theft, to invasive surveillance, to the automation of bias, to tax- evasion, the world run by corporate-owned machines is proving to be anything but “magical.”

The main objective of this study was to extract the essential oils from Clerodendrum formicarum and
Syzygium cordatum in order to determine the anticancer activity and establish the chemical constituents of
that kind of essential oils. Hence, we have used hydrodistillation method to obtain the desired extracts or
samples of essential oils. Indeed, the assessment of the anticancer activities showed that, at 100 µg/mL, the
essential oils from S. cordatum inhibited the proliferation (98.2%) of breast cancer (MCF-7) cells. In the
same context, the essential oils from C. formicarum also inhibited the proliferation (98.9%) of breast cancer
(MCF-7) cells. We have additionally determined the chemical composition of the essential oils by GC-MS
and identified 17 compounds in C. formicarum including caryophyllene (18.6%), (E)-3,7-dimethylocta1,3,6-triene (7.6%), β-Myrcene (6.2%), and [1S-(1α, 7α, 8α)]-1,8a-dimethyl-7-(1-methylethenyl)-
1,2,3,5,6,7,8,8a-octahydronaphthalene (5.6%) as major compounds. We have observed an unknown
compound (25%) in the essential oils from C. formicarum (H-12) The chemical analysis showed 28
compounds in S. cordatum (HE-9) essential oils such as caryophyllene (7.2%) and cedrene (6.7%) as major

The presence of an aberrant right hepatic artery is the most frequently encountered vascular anomaly during
pancreaticoduodenectomy, and its recognition and preservation are of paramount importance to prevent
ischemia of the bile duct and consequently the bilioenteric anastomosis, which can lead to anastomotic leak
or dehiscence and fistula. In this case report, we describe proximal branching of the common hepatic artery
(CHA) to give rise to a replaced right hepatic artery (RHA), which courses posterior to the portal vein (PV)
and common bile duct (CBD) to the right lobe of the liver. The location of this replaced RHA in the
hepatoduodenal ligament is consistent with the location of a replaced RHA described by the Michels
classification, although with the important distinction that origin was the CHA instead of the superior
mesenteric artery (SMA). From our review of the current literature, this is the first published description of
such an anatomic course of the RHA.
A remarkable pogonophoran from a desalted shallow near the mouth of the Yenisey River in the Kara Sea, with the description of a new species of the genus Galathealinum (Annelida: Pogonophora: Frenulata)
Authors: Smirnov R.V. , Zaitseva O.V. , Vedenin A.A.
Published: July 2020

A new species of Pogonophora obtained from one station at a depth of 25 m from near the Dikson Island in the Kara Sea is described. Galathealinum karaense sp. nov. is one of the largest pogonophorans, the first known representative of the rare genus Galathealinum Kirkegaard, 1956 in the Eurasian part of the Arctic Ocean and a highly unusual finding for the desalted shallow of the Yenisey Gulf. Several characters occurring in the new species are rare or unique among the congeners: under-developed, hardly discernible frills on the tube segments, extremely thin felted fibres in the external layer of the tube, and very faintly separated papillae in the anterior part of the trunk. Morphological characters useful in distinguishing species within the genus Galathealinum are defined and summarised in a table. Diagnosis of the genus Galathealinum is emended and supplemented by new characters. Additionally, three taxonomic keys are provided to the species of Galathealinum and to the known species of the Arctic pogonophorans using either animals or their empty tubes only, with the brief zoogeographical information on each Arctic species.

An assessment of the population of red steppe breed cows by exterior and productive characteristics in the formation of production groups allocated for the degree of development of live weight, assessment of the exterior, milk yield, milk fat, milk fat, kg. The following selection parameters were calculated: for live weight - selection group X≥595 kg, production 595> X≥514 kg, marriage X<514; assessment of the exterior – selection group X≥9,46, production 9,46> X≥7,78, marriage X<7,78; for a milk yield for 305 days of lactation, a selection group X≥4481 kg, production 4481> X≥2829 kg, marriage X <2829 kg; milk fat content – selection group X≥4,35 kg, production 4,35> X≥3,99 kg, marriage X<3,99; milk fat - selection group X≥186 kg, production group 186> X≥118kg, marriage X<118 kg. Comparative assessment of the herd shows that animals of the breeding group in live weight by 18,7% exceed the breed standard, in milk yield by 8,7%, in milk fat 20,7%. Evaluation of animal grouping by milk yield shows that cows of a selection group exceed the breed standard by live weight by 6,1%, milk yield by 38,5%, milk fat by 54,3% Animals of the breeding group for milk fat exceed the breed standard by 6,1% in live weight, 36%, in milk yield, in milk fat 53,8%. The selection of the breeding group by body weight contributes to the formation of an array of animals of tall, stretched type with increased milk yield and milk fat. Cows with high milk yield differ from their peers in their greater body weight, milk yield index and milk fat productivity, and have a stretched and wide-grip physique. Uterus with high productivity in milk fat differ from their peers in greater body weight, milk yield, milk yield index, and have a more stretched constitution. For most of the identified dependencies, a significant difference was noted between the traits of different breeding groups. It should be noted that, regardless of the choice of the main feature, there is a tendency to form an array of animals that are distinguished by tall and stretched physique.

Published: July 2020

The influence of flour composite mixes from wheat, lentil and millet flours in different proportions on baker’s yeast biotechnological properties is studded. It is shown, that multigrain bread with 5–10 % lentil/millet flour addition has better sensory qualities than traditional wheat bread. It is revealed, that introduction of 20 or 30 % lentil or millet flour into the flour mixture has the best stimulating effect for the yeast growth. In particular, the addition of average volumes of lentil or millet flour is accompanied by an increase in yeasts’ rising power 5 times. It is established, that introduction of 40 % lentil flour and complex three-component flour mixture formation reduces the specific growth rate of baker’s yeast by 1.5–2 times compared with the control. The best physicochemical parameters are recorded in samples, containing 30 % millet or 30 % lentil flour.

In controlled experiments during planned studies of cattle for leukemia, animals that showed leukemoid changes in blood – quantitative redistribution of granulocytes and agranulocytes-were identified. Individual analysis revealed that granulocytosis was detected in animals with inflammatory processes. In addition, the article presents comparative indicators of serum proteins in cows at the hematological stage of the leukemic process, with the manifestation of leukemoid reactions and in clinically healthy cows. Characteristic changes in the synthesis of immunoglobulins in cows with leukemia and leukemoid changes in the morphological composition of blood were established. With successful treatment of inflammatory processes, the hematological status of cows is restored to the initial indicators.
