Authors: Bakhtushkina A.I.
Published: November 2019

The purpose of the research is to study the lifespan of Lipoptena cervi imaginal forms under exposure of different temperature conditions and humidity. Materials and methods. L. cervi caught in natural habitats and taken off from marals’ skin served as the material for the research. Overall, 38 samplings have been conducted, 18 thousand L. cervi have been sampled. Caught imagoes were put into mattresses after suffocation with ether-chloroform mixture; the most viable insects were used in experiments. Research for L. cervi lifespan except host of volatiles (not fed) and taken off from marals were conducted under exposure of different temperature conditions and humidity as well as in different types of cages, in wool on skins that were taken off. L. cervi were kept in small quantities in free cages made of capron mesh. Results and discussion. The winged forms under mid-mountain zone conditions of the Republic of Altai can be seen from June up to October; wingless forms (on the feeders’ body) can be seen from June of the current year up to June of the following year and including. Chrysalides are present in nature throughout the year, as L. cervi can’t hatch out from chrysalides of the previous year generation fast enough in June and July before the chrysalides of the new generation begin to appear. The weight of the hatched out L. cervi is 7.9-11.5 mg, they die if the weight is decreased up to 3.0-3.9 mg. It would appear that, the energy and water reserve is 4.9-7.6 mg per one insect. Young not fed L. cervi live rather longer than sexually mature insects. The L. cervi lifespan reliably increases without food as the humidity increases. The longest lifespan is when the humidity is about 60-80% and temperature is about 14-16°С. In laboratory conditions, at the air temperature of about 20-25°C, the humidity of about 60-80%, and moderate airing the chrysalis development lasts for 90 days on the average.

White outbred rats, mice and guinea pigs were used in the experiment. In the study of acute oral toxicity in mice and rats, acute cutaneous toxicity, subacute toxicity, irritant action of an aqueous suspension of a combination of active substances, allergenic properties of the collar «Neoterika Protecto 12» conventional methods were used. Results and discussion. The median lethal doses LD50 for oral supplementation to white mice (1070 mg/kg) and oral supplementation to white rats (3210 mg/kg) were diagnosed, which allowed to designate the preparation to the 3rd hazard class (moderately hazardous substances). In the study of acute cutaneous toxicity on white rats LD50 amounted to more than 10 000 mg/kg, therefore, according to the generally accepted hygienic classification, the preparation belongs to the 4th hazard class during cutaneous application. In the study of subacute toxicity of the medication on rats for 6 months after application of the aqueous suspension of the combination of active ingredients in doses of 1000, 500 and 200 mg/kg, no changes in general state and behavior were observed in animals. When an aqueous suspension of a combination of active substances of the collar was applied to the skin of rats, there were no signs of irritant effect, but a mild effect on the mucous membrane of the guinea pig's eyes was recorded. It was found that the preparation does not have allergic and sensitizing effects.

The purpose of the research is to determine the therapeutic efficiency of the moxidectin-based domestic anthelmintics and develop protocol of medical and preventive activities in dog's dirofilariasis under the conditions of Central Black Earth Region of Russia. Materials and methods. Blood from ill dogs infected naturally with both species of dirofilariases that was tested for presence of helminths' larvae by Millipore® (Ireland) membrane filter method served as the material for the research. Experimental groups were formed out of 76 infected with dirofilariasis dogs aged 1-14 years under the principle of analogs to determine the therapeutic efficiency of moxidectin-based domestic anthelmintics. Drugs weren’t administered into intact animals of the first group (n = 21). MKTc Ankir-B® in the dose of 500 mg per animal was administered orally to animals of the second group (n = 19) as placebo. Inspector Total C anthelmintic was administered in the single dose of 2.5 mg per kg of body weight to the third group of dogs (n = 19) epidermally, Helmimax anthelmintic was administered in the single dose of 0.25 mg per kg of body weight orally to animals of the fourth group (n = 17). During experiments animals were examined clinically and hemolarvoscopically before administration of drugs and on the 3rd, 14th, 30th, 45th and 60th day after administration. Results and discussion. Inspector Total C anthelmintic in the dose of 2.5 mg per kg according to an active substance in the form of spot-on and Helmimax anthelmintic in the dose of 0.25 mg per kg according to an active substance in single administration in dogs infected with Dirofilaria immitis and D. repens species dirofilariasis have 100 % microfilaricidal efficiency. Anthelmintics do not change physiological parameters, do not cause side effects and well tolerated by animals. It should be noted that drugs therapeutic action starts on the third day after treatment regardless of the infection intensity and germ's species.

Published: November 2019

The purpose of the research to study the antihelminthic efficiency of the new antihelminthic medication asmegum. Materials and methods. The object of the research is the antihelminthic medication asmegum, which has been synthesized at the Institute of Chemistry and Chemical Technologies of the National Academy of Sciences of the Kyrgyz Republic by streamlined synthesis. Asmegum was tested on 45 spontaneously infested sheep born in 2015 with the body weight of about 40-50 kg at the experimental base of the Kyrgyz Scientific Research Institute of Veterinary named after A. Duysheev. Animals were divided into 9 groups, 5 animals in each group, according to the principle of analogues. All test animals were kept under the same conditions. Asmegum was given orally as a single dose in the form of water emulsion, powder and medicated feed mixture at a dose of 50 mg/kg of live weight. Animals from the 1st, 2nd and 3rd groups received asmegum in a water emulsion form. Animals from the 4th, 5th and 6th groups received the medication in a powder form. Sheep from the 7th, 8th and 9th groups received asmegum in a medicated feed mixture form. The animals were monitored during 10 days. The anthelminthic activity of the medication was determined according to the results of coproovolarscopical (by Fulleborn's method, sequential washing method and Berman's method) research in 10 days after giving medication. The therapeutic efficiency of the anthelmintic agent was assessed according to the requirements of the World Association for the Advancement of Veterinary Parasitology (1995). Results and discussion. The asmegum efficiency at a dose of 50 mg/kg versus strongylata, nematodiroses and dicrocelium was determined. Its efficiency in strongylatosis, dicroceliosis and nematodirus was 90.3-91.28%, 89.76-92.0% and 86.52-91.56% respectively. The medication dosage form did not effect its efficiency. Asmegum administration in a recommended dose did not induce adverse events in animals. The medication promoted the intestine function regeneration. Sheep treated with asmegun bulked up quickly due to presence of asparaginic acid in its composition.

Towards sustainable developing cities: A simplified forecasting model for grid-tied PV using monthly electricity bills
Authors: Gerber Stefan , Rix Arnold , Booysen Marthinus Johannes
Published: November 2019

The recent reductions in PV costs and the convenient concurrence of insolation and schools' energy usage have resulted in increased interest in augmenting supply with solar PV to save on energy costs and unburden the grid in developing countries.However, optimal sizing of PV solutions requires a detailed analysis and hourly simulation to match demand, council tariff structures (incl.\ import vs.\ export rates) and geography. This complexity exposes already resource-constrained authorities to abuse by overzealous and unwitting suppliers, and currently impedes large-scale deployment of solar PV in a sunshiny cities depraved of its requisite energy. We present a novel approach to forecast schools' hourly demand using only monthly utility bills and a trained forecasting model. We also propose an iterative solar sizing technique to assess the economic viability of using PV at schools to support government and city council officials. The results show that the method is able to forecast annual energy usage and monthly demand to within 5% and 6% respectively, while accurately determining the potential return on investment.

Sustained volcanic impact and ecosystem disturbance over continental Europe during the Early Holocene
Authors: Zanon Marco , Feeser Ingo , Dreibrodt Stefan , Schwark Lorenz , van den Bogaard Christel , Dörfler Walter
Published: November 2019

Estimating the environmental and societal impact of recent volcanic eruptions is a task aided by direct measurements and historical sources. Beyond the reach of first-hand accounts, our understanding of pre-historic volcanism is often hindered by the dating uncertainties inherent to stratigraphic archives. Here, we minimise this source of error by analysing the annually laminated sequences of two European lakes. We focus on environmental transformations that occurred in the decades preceding and following the deposition of the Icelandic Saksunarvatn tephra, dated between ca. 10,300 and 10,200 cal. BP. Evidence for continuous eruptive activity pre-dates the tephra deposition by nearly two decades, revealing a period of sustained volcanism and its effects on aquatic and terrestrial ecosystems. These results provide a new insight into the spatial and temporal effects of clustered volcanic eruptions. As such, they might prove useful to refine the simulation of volcanic forcing on continental ecosystems and to evaluate the resilience of prehistoric societies against sudden environmental downturns.
Interval Timing and Motivation are Dissociable when Interval-Initiating Responses are Discriminable from Target Responses
Authors: Daniels Carter W. , Sanabria Federico
Published: November 2019

Data have accumulated suggesting that motivation and timing are correlated processes, yet few studies have tested whether motivation and timing are procedurally dissociable. This may be attributed to the fact that the most common framework in which to study timing, the pacemaker-accumulator model, does not readily suggest a route by which to dissociate motivation and timing. In contrast, the behavioral systems framework suggests that motivation and timing could be dissociated if subjects were trained in response-initiated (RI) interval-timing procedures rather than in common externally-initiated (EI) procedures. RI procedures were predicted to enhance temporal control and yield timing performance robust to fluctuations in motivation. Experiment 1 tested this hypothesis by training rats to either initiate switch-timing trials with a single press on the lever associated with the shorter FI schedule (SL-RI), or wait for switch-timing trials to be initiated (EI). Motivation was varied through pre-feeding. SL-RI and EI rats showed similar levels of temporal control and sensitivity to pre-feeding in their switch-timing performance. Experiment 2 tested a revised RI hypothesis, the discriminative-RI hypothesis, which predicts that as the trial-initiating response becomes progressively different from target responses, motivation and timing are increasingly dissociated. This experiment replicated Experiment 1 and added a trial-initiating condition in which a nose-poke into a nose port (NP-RI) initiated trials. As predicted, the sensitivity of switching-timing performance to pre-feeding scaled such that EI > SL-RI > NP-RI. These data suggest that it is possible to dissociate timing and motivation, challenging the notion that these processes are correlated.
Schematic Support increases Memory Strategy Use in Young and Older Adults
Authors: Kuhns Jack , Touron Dayna R
Published: November 2019

During learning, a shift in processing often occurs with increased task experience, where initialslow, algorithmic processing proceeds into fast, retrieval-based processing. Older adults are slower than young adults in the rate at which this shift occurs, in part due a reluctance to use a retrieval strategy. The present research employed task materials that alleviate age-related differences in associative memory so that participants could rely on prior knowledge, or schematic support. The goal was to determine whether older adults’ retrieval reluctance is due to a general avoidance of using the retrieval strategy or to low confidence in their memory for unfamiliar task materials. Participants completed two learning tasks: the Noun-Pair Lookup Task, where task materials consist of unrelated noun pairs, and an isomorph, the Grocery-Price Look Task, where task materials were grocery-items and prices. In this second task, the prices were either market-priced and consistent with everyday experience or were overpriced. Older adults were retrieval reluctant in the Noun-Pair Lookup Task, replicating previous findings. Stark condition differences were found in the Grocery-Price Lookup Task; older adults shifted much sooner for market-priced materials than for overpriced materials, and young adults shifted much later than expected for overpriced materials, where their final levels of learning were inconsistent with their memory use. Condition differences in retrieval use were substantially larger than the differences in retrieval accuracy. These results imply that confidence in using the retrieval strategy matters for both young and older adults, and that retrieval reluctance is not solely an age-related phenomenon.
Everyday Music in Infancy
Authors: Mendoza Jennifer K. , Fausey Caitlin M.
Published: November 2019

Infants enculturate to their soundscape over the first year of life, yet theories of how they do so rarely make contact with details about the sounds available in everyday life. Here, we report on properties of a ubiquitous early ecology in which foundational skills get built: music. We captured daylong recordings from 35 infants ages 6-12 months at home and fully double-coded 467 hours of everyday sounds for music and its features, tunes, and voices. Analyses of this first-of-its-kind corpus revealed two distributional properties of infants’ everyday musical ecology. First, infants encountered vocal music in over half, and instrumental in over three-quarters, of everyday music. Live sources generated one-third, and recorded sources three-quarters, of everyday music. Second, infants did not encounter each individual tune and voice in their day equally often. Instead, the most available identity cumulated to many more seconds of the day than would be expected under a uniform distribution. These properties of the everyday musical ecology in human infancy are different from what is discoverable in environments highly constrained by context (e.g., laboratories) and time (e.g., minutes rather than hours). Together with recent insights about the everyday motor, language, and visual ecologies of infancy, these findings reinforce an emerging priority to build theories of development that address the opportunities and challenges of real input encountered by real learners.

This study investigates the nature and context-based peculiarities of sustainability practices related to the supply chain of oil servicing firms operating in the downstream sector of Nigerian oil and gas industry. The supply chain management practices of oil servicing firms are crucial to the functioning of the downstream sector of the oil and gas industry. However, the literature on their supply chain sustainability is scant and scattered. To fully explore this field; therefore, survey data were collected from key practitioners in the industry and analysed using descriptive statistics. The results show that the supply chain management practices of oil servicing companies relating to designing, producing, marketing, delivering, and supporting the products of their clients rarely factor in the requirements of sustainability practices. Accordingly, this study points out strategic interventions that could help in greening the supply chain practices of oil servicing companies operating in the downstream sector of the Nigerian oil and gas industry

Published: November 2019

We have developed mathematical models and performed simulations of transfer of short optical impulses through the cloud layer into space. The main cloud layer variables chosen are its vertical optical and geometrical depths. The physical processes behind the time-amplitude characteristics of the radiative field are studied. It is shown that the presence of a cloud layer results in a formation of a secondary source at the upper boundary of a cloud and in substantial distortions in the temporal pattern of the initial impulse.

Published: November 2019

A concept of the comprehensive assessment of soil contamination is proposed. In this concept, the conclusion regarding the presence of toxic substances in a sample, which is being analyzed, is connected with the inhibition of enzymatic reactions that are responsible for various functions of a live organism, such as luminescence, respiration, etc., these functions are taken as test functions in classical bioassays, which are using live objects (luminous bacteria, daphnia, algae, etc.). The regularities of the impact of different classes of toxicants on the activity of individual enzymes or coupled oligo-enzyme chains have been established. These enzyme reactions are selected as potential test objects - markers of pollution. The set of enzymatic bioassays consists of three enzyme systems with maximum sensitivity to different classes of toxicants: butyrylcholinesterase, NAD(P)H:FMN‑oxidoreductase + luciferase and lactate dehydrogenase + NAD(P)H:FMN‑oxidoreductase + luciferase. The possibility of using enzymes instead of living organisms in the bioassay of natural complex systems is shown.

El trabajo hace parte de la investigación titulada: La arquitectura del concepto de goce en la obra de Jacques Lacan, donde se aborda la relación del goce con el amor en la estructura que Freud denominó como perversa, considerando el masoquismo desde la pulsión de muerte y articulando la posición subjetiva en Psicoanálisis. Por lo cual, el artículo ha intentado abordar un trayecto que permite representar la posición subjetiva en el complejo de Edipo como el amor, no como la subjetividad que intenta demostrar un lugar imaginario en el acto de amar, sino como la identificación con el síntoma, desde la obra de Jaques Lacan. La propuesta de esta relación permite articular las obras completas de Freud y los seminarios de Lacan, en especial el seminario VIII (Transferencia, 1961) y el XX (Aun, 1973); donde el significado del amor ocupa su lugar en el deseo que devela el goce. Por lo tanto, se ha llevado a cabo una metodología histórico hermenéutica y como técnica de recolección de información la revisión documental, agrupando las categorías de análisis en el presente escrito y el resumen de uno de los capítulos de la monografía mencionada en primer orden.
Von der Feminisierung zur Entmaskulinisierung

Published: November 2019

Basierend auf der Tradition französischer Epistemologie thematisiert dieser Beitrag die Durchlässigkeit zwischen Alltags- und Wissenschaftswissen. Auf der Grundlage des Konzepts des ‚epistemologischen Bruchs‘ werden humanmedizinische und sozialwissenschaftliche Veröffentlichungen betrachtet, in denen der Begriff der Feminisierung verwendet wird, wobei beleuchtet werden soll, inwiefern er ein ‚Erkenntnishindernis‘ (Gaston Bachelard) darstellt. Anschließend an diese epistemologische Reflexion wird ein neues begriffliches Instrumentarium zur soziologischen Erforschung des Wandels der Geschlechterverhältnisse in der Berufssphäre skizziert, nämlich die Unterscheidung von drei Entmaskulinisierungstypen.

BACKGROUND: Previous studies have indicated that the kinematics of the knee joint affect the trunk and pelvis during gait. However, the factors that influence trunk movement in knee osteoarthritis patients during gait after surgery remain unclear. OBJECTIVE: To examine the effect of total knee arthroplasty (TKA) on trunk movement during gait by comparing knee osteoarthritis patients with healthy controls. METHODS: Fourteen medial knee osteoarthritis patients who underwent initial unilateral TKA and 11 controls participated in this study. Knee and hip joint flexion and trunk and pelvic tilts during gait were acquired using a three-dimensional motion analysis system. Knee joint range of motion, pain, and kinematic data were collected preoperatively and 1 year postoperatively for knee osteoarthritis patients. RESULTS: Knee extension limitation and pain significantly improved postoperatively compared with preoperative stages. Preoperatively, the peak anterior trunk tilt during the stance phase was significantly larger in osteoarthritis patients than in controls. The peak anterior trunk tilt during the stance phase was significantly smaller postoperatively than at preoperative stages. CONCLUSIONS: These results suggest that after TKA, the trunk movements of knee osteoarthritis patients were approximately equal to those of controls, with improvement in clinical outcomes such as knee extension limitation and pain.

Inflammation resolution is regulated by specialized pro-resolving lipid mediators (SPMs) and the levels of SPMs are found decreased in Alzheimer’s disease (AD) brain. We have previously found that one of the SPMs, Maresin1 (MaR1), improved neuronal survival and increase microglial phagocytosis of amyloid-β 1-42 (Aβ42); however, the mechanisms underlying the protective mechanism remain further investigation. We aim to investigate the effects of MaR1 on microglial chemotaxis and activation in this study. Both indirect and direct primary neuron and microglia co-culture system was used in this study. Our results showed MaR1 downregulated the increased microglial chemotaxis induced by Aβ42. The microglial inactivation marker CD200R was downregulated by Aβ42 and upregulated by MaR1. Pro-inflammatory cytokines secretion such as tumor necrosis factor (TNF)- α were increased by Aβ42 and these changes were revised by MaR1 treatment. In addition, the levels of chemokine monocyte chemoattractant protein (MCP)-1 were increased while the levels of anti-inflammatory factor IL-10 secretion were decreased by Aβ42, and these changes were abolished by MaR1 treatment. Moreover, by proteomics analysis, we identified cell signaling pathways affected by MaR1 were not only limited to inflammation-related pathways such as P38, but also in pathways involved in cell survival, autophagy, axon formation, and apoptosis, including PI3K/AKT, mTOR, ERK, caspase3, Cdc42, and p75NTR. In conclusion, MaR1 promoted inflammation resolution by inhibiting chemotaxis and regulating activation of microglia. MaR1 played a neuroprotective role by affecting cell signaling pathways involving inflammation, cell survival, autophagy, axon formation, and apoptosis inhibition.

The risk of dementia and mild cognitive impairment between older adults in same-sex relationships and those in opposite-sex relationships have been found to be statistically not different. However, studies examining subjective cognitive decline (SCD) among sexual and gender minority populations (SGM) are lacking. The primary objective was to determine if SGM report greater SCD compared to non-SGM populations in a U.S. population-based sample of non-institutionalized adults aged 45 and older. The secondary objective was to assess the association between gender and SCD. Cross-sectional data were obtained from the 2016 Behavioral Risk Factor Surveillance System ( n = 36,734). There were 1,094 SGM adults in the sample. Descriptive statistics examined sociodemographic characteristics and their distribution by SCD and SGM status. Crude and multivariable logistic regression models were used to determine the association between SGM status, gender, and SCD. Adjusted models controlled for age, race/ethnicity, income, education, employment, marital status, depression, and diabetes. Statistically significant differences in SGM status and SCD existed by age, race/ethnicity, education, employment, marital status, and depression. Differences in SCD also existed by income and diabetes status. There was no statistically significant association between SGM status and SCD (OR: 0.88; 95% CI: 0.63–1.24). However, men had 64% higher odds (OR: 1.64; 95% CI: 1.44–1.88) of reporting SCD compared to women. Future studies examining the potential reasons for this null association, including resilience and/or premature aging are warranted. Future research assessing potential reasons for gender differences in SCD, whether physiological or environmental, is also needed.
Carnosic Acid Reverses the Inhibition of ApoE4 on Cell Surface Level of ApoER2 and Reelin Signaling Pathway

The cell surface level of apolipoprotein E receptor 2 (ApoER2) increases by cyclic transport of ApoER2 and then activates Reelin signaling pathway to exert neuroprotective function in AD. ApoER2 ligand Apolipoprotein E4 (ApoE4) inhibits the recycling of ApoER2 to the cell surface rendering neurons unresponsive to Reelin. Carnosic acid (CA) is proven to possess neuroprotective and neurotrophic functions in Alzheimer’s disease (AD) mouse model. However, there are few reports about how ApoE4 impairs the recycling of ApoER2 and if CA can affect the cyclic transport of ApoER2. In this study, we demonstrated that ApoE4 attenuates the binding of sorting nexin 17 (SNX17) to ApoER2 and inhibits the recycling of ApoER2, resulting in decreased cell surface level of ApoER2. Further, we found that CA enhances the binding of SNX17 to ApoER2, counteracts the negative effects of ApoE4 on the cell surface level of ApoER2 to reverse the ApoE4-induced reduction in Reelin signaling activation by increasing the phosphorylation of the N-methyl-D-aspartate receptor (NMDAR) and cAMP-response element-binding protein (CREB) and the expression of Gria2. Thus, CA promotes neurite growth inhibited by ApoE4. Our work suggests that CA may be a potential approach to attenuate the risk of ApoE4-associated AD.

INTRODUCTION:

Extremely preterm infants are a population of high risk for morbidity and mortality. NICU's staffing is often lower during nights, weekends and holidays than weekdays, and this fact may contribute to higher morbidities and mortality. Our aim was to analyze the neonatal morbidity and mortality of very preterm infants delivered at our center and admitted to the NICU during the night period, weekends and holidays compared to that registered on weekday admissions.

METHODS:

A retrospective study was conducted at our level III NICU, including data on mother, pregnancy, delivery, and neonatal outcomes of preterm infants with a gestational age below 30 weeks, admitted between January 1st 2005 and December 31st 2017. Statistical analysis was performed using IBM SPSS® Statistics 23.

RESULTS:

220 infants were included in the study; median gestational age 27 weeks (min = 23; max = 29); median birth weight of 922 g (min = 360; max1555); 95 (43.2%) infants were delivered during weekdays and 125 (56.8%) were delivered during weeknights, weekends and holidays. There were no differences on mother's age, pregnancy complications, Apgar scores, birth weights, gestational ages and gender between the two groups. C-sections ( p = 0.006), and small for gestational age infants ( p = 0.010) were more prevalent in week day births. Chorioamnionitis with chorionic vasculitis ( p = 0.028) and cystic periventricular leukomalacia ( p = 0.032) were more prevalent in those delivered during the night period, weekends and holidays. In the multivariate analysis, cystic periventricular leukomalacia was not associated to a deliver during weeknights, weekends and holidays (OR = 0.580; 95% CI: 0.19–1.71, p = 0.324).

CONCLUSION:

We did not find any increased morbidity and mortality associated with a birth during nights, weekends and holidays compared to that registered on weekday admissions.
