Published: October 2020

An important common hematological finding in veterinary patients with chronic kidney disease (CKD) in more advanced cases is normocytic, normochromic and non-regenerative anemia, which causes numerous clinical signs, including muscle weakness, lethargy, anorexia and weight loss. Several factors of CKD are known to lead to anemia in animals, including low levels of erythropoietin hormone by washing, reduction of red blood cells as a result of a uremic condition and increased risk of oxidation, nutritional deficiencies from inappropriate use in erythropoiesis (due to anorexia) and mucosal ulcerations that lead to blood loss. The aim of this paper is to report the case of a canine patient diagnosed with chronic kidney disease presenting with normocytic, normochromic and non-regenerative anemia, in which treatment with recombinant human erythropoietin should be chosen, resulting in hematological effects as well as benefits how it improves the quality of life.
Avaliação da terapia com células-tronco mesenquimais halógenas em doença renal crônica de cães e gatos
Authors: Brunel Hilana
Published: October 2020

Chronic kidney disease (CKD), a disease characterized by tubulo-interstitial inflammation, tubular atrophy and interstitial fibrosis with progressive loss of renal function, has become a relatively common condition in dogs and cats. Due to the fact that renal transplantation is not yet a viable option in veterinary med-icine, studies have been carried out to evaluate the possibility of treatment of CKD with mesenchymal stem cells (MSCs) due to the anti-inflammatory, anti-oxidant, an-ti-fibrotic and immunomodulatory responses that these cells possess. Eleven patients with CKD (6 dogs and 5 cats) were evaluated and submitted to therapy with halogen MSCs. All 5 cats and 4 out of the 6 dogs had a decrease in serum creatinine levels after cell transplantation, indicating that there was a significant decrease in creati-nine in dogs (P = 0.0238). There was also a considerable decrease in the frequency of vomiting (P

PHILOGENETIC DIVERSITY OF FUNGI OF THE GENUS PENICILLIUM AND TALAROMYCES ASSOCIATED WITH BROWN ALGAE OF THE GENUS SARGASSUM
Authors: Kirichuk N. , Pivkin M. , Hudyakova Yu.
Published: October 2020

The results of the investigation of Penicillium sensu lato phylogenetic diversity of brown algae Sargassum spp. (the Sea of Japan) are presented in this article. Seventeen fungal strains were studied using traditional methods of phenotypic investigations and modern molecular-genetic approaches. As a result of phylogenetic analysis of ITS and BenA gene sequences, Penicillium species from five sections were revealed (sections Fasciculata, Paradoxa, Ramosa, Canescentia, Aspergilloides). One strain was identified as species of Talaromyces which more related to section Talaromyces. Five species (P. spinulosum, P. subspinulosum, P. roseomaculatum, P. thomii, P. murcianum, P. antarcticum) were identified based on BenA gene analysis. For species identification of some strains additional analysis of genetic and phenotypic features is necessary.
STRUCTURAL TRANSFORMATION OF THE NICRMNSI – FE NANODISPERSE SYSTEM IN A CORROSIVE ENVIRONMENT
Authors: Salikova E.
Published: October 2020

Structural changes in the NiCrMnSi nanodisperse system deposited on a metal Fe substrate by the HVOF method in a CORROSIVE H2S medium (pH-2,4) were studied. Structural transformation in the NiCrMnSi - Fe system is caused by the oxidation process in a hydrogen sulfide-containing medium. It was found that 216 hours later, when interacting with a corrosive medium, the boundary zone of the interfacial boundaries of the iron substrate with the NiCrMnSi nanodisperse system was destroyed. The evolution of the destruction of the border zone is studied using the IMAGEJ software package.

Decoupling Seascapes
Authors: Hamada Shingo
Published: October 2020

The roles played in fishery resource management by the nonhuman species that coevolve with humans are often marginalized in both discourse and practice. Built on existing reviews of the multispecies ethnography of maritime conservation, domestication, and marine biology, this article aims to reconceptualize the politics of difference in stock enhancement. By examining the herring stock enhancement program in Japan as an assemblage of multispecies inter- and intra-action in the context of marine science and seascaping, this article recontextualizes fisheries management and crosses the methodological and ontological borders in maritime studies. The article shows that multispecies ethnography serves as a heuristic means to describe the co-constitution of seascapes, which are beings, things, and bodies of information and processes that shape marine surroundings, or what fisheries biologists and fisheries resource managers tend to overlook as mere background.
Appropriate Targets
Authors: Durney Florence
Published: October 2020

With the International Whaling Commission’s 1982 moratorium on commercial whaling in force, much of today’s cetacean hunting is done by traditional or indigenous communities for subsistence use. However, many communities continue to face pressure from other global stakeholders to stop. Informed by my research with marine hunters in Indonesia, this article combines scholarship from biology, philosophy, and law with global anthropology on cetacean hunting groups to explore a set of recurring arguments arising between hunting communities, management and conservation bodies, and publics. These include the role of charismatic species in Western imagination and conservation; how understandings of animal sentience determine acceptable prey; disputes about the authenticity of and control over traditional hunting practice; and the entanglement of cultural sovereignty and rights to animal resources. Bringing these arguments together allows for an examination of how the dominant global discourse about traditional whaling is shaped and how it affects extant hunting communities.
Documenting Sea Change
Authors: Sullivan Kathleen M.
Published: October 2020

This review examines social science and practitioner literature regarding the relationship between ocean sciences big data projects and ocean governance. I contend that three overarching approaches to the study of the development of ocean sciences big data techne (the arts of data creation, management, and sharing) and data technologies can be discerned. The first approach traces histories of ocean sciences data technologies, highlighting the significant role of governments in their development. The second approach is comprised of an oceanic contribution to the study of ontological politics. The third takes a human-social centered approach, examining the networks of people and practices responsible for creating and maintaining ocean sciences big data infrastructure. The three approaches make possible a comparative reflection on the entangled ethical strands at work in the literature.

Limited utility of 5-ALA optical fluorescence in endoscopic endonasal skull base surgery: a multicenter retrospective study
Authors: Micko Alexander , Rapoport Benjamin I. , Youngerman Brett E. , Fong Reginald P. , Kosty Jennifer , Brunswick Andrew , Shahrestani Shane , Zada Gabriel , Schwartz Theodore H.
Published: October 2020

OBJECTIVE

Incomplete resection of skull base pathology may result in local tumor recurrence. This study investigates the utility of 5-aminolevulinic acid (5-ALA) fluorescence during endoscopic endonasal approaches (EEAs) to increase visibility of pathologic tissue.

METHODS

This retrospective multicenter series comprises patients with planned resection of an anterior skull base lesion who received preoperative 5-ALA at two tertiary care centers. Diagnostic use of a blue light endoscope was performed during EEA for all cases. Demographic and tumor characteristics as well as fluorescence status, quality, and homogeneity were assessed for each skull base pathology.

RESULTS

Twenty-eight skull base pathologies underwent blue-light EEA with preoperative 5-ALA, including 15 pituitary adenomas (54%), 4 meningiomas (14%), 3 craniopharyngiomas (11%), 2 Rathke’s cleft cysts (7%), as well as plasmacytoma, esthesioneuroblastoma, and sinonasal squamous cell carcinoma. Of these, 6 (21%) of 28 showed invasive growth into surrounding structures such as dura, bone, or compartments of the cavernous sinus. Tumor fluorescence was detected in 2 cases (7%), with strong fluorescence in 1 tuberculum sellae meningioma and vague fluorescence in 1 pituicytoma. In all other cases fluorescence was absent. Faint fluorescence of the normal pituitary gland was seen in 1 (7%) of 15 cases. A comparison between the particular tumor entities as well as a correlation between invasiveness, WHO grade, Ki-67, and positive fluorescence did not show any significant association.

CONCLUSIONS

With the possible exception of meningiomas, 5-ALA fluorescence has limited utility in the majority of endonasal skull base surgeries, although other pathology may be worth investigating.
Assessment of burnout prevention and wellness programs for US-based neurosurgical faculty and residents: a systematic review of the literature
Authors: Berardo Laura , Gerges Christina , Wright James , Stout Amber , Shah Hamid , Papanastassiou Alexander , Kimmell Kristopher , _ _
Published: October 2020

OBJECTIVE

Neurosurgeon burnout is a serious and prevalent issue that has been shown to impact professionalism, physician health, and patient outcomes. Interventions targeting physician burnout primarily focus on improving physician wellness. Many academic neurosurgery programs have established wellness curricula to combat burnout and improve wellness. No official recommendations exist for establishing a wellness program that effectively targets sources of burnout. The aim of this review was to examine measures of burnout and report objective results of wellness interventions for neurosurgical faculty and residents.

METHODS

Two systematic literature reviews were performed in parallel, in accordance with PRISMA 2009 guidelines. Following removal of duplicates, a query of PubMed/MEDLINE, Scopus, Ovid, Cochrane, and EMBASE databases yielded 134 resident-related articles and 208 faculty-related articles for abstract screening. After abstract screening, 17 articles with a primary focus of resident wellness and 10 with a focus on faculty wellness met criteria for full-text screening. Of the total 27 screened articles, 9 (6 resident, 2 faculty, 1 both resident and faculty) met criteria and were included in the final analysis. Article quality was assessed using the Joanna Briggs Institute critical appraisal tools for cohort studies.

RESULTS

Included studies reported burnout rates for neurosurgery residents of 30%–67%. Work-life imbalance, imbalance of duties, inadequate operative exposure, and hostile faculty were contributors to burnout. The 2 included studies reported burnout rates for neurosurgery faculty members of 27% and 56.7%. Psychosocial stressors, relational stressors, and financial uncertainty were generally associated with increased feelings of burnout. Of the 4 studies reporting on outcomes of wellness initiatives included in this review, 3 reported a positive impact of the wellness interventions and 1 study reported no significant improvement after implementing a wellness initiative.

CONCLUSIONS

Burnout among neurosurgical faculty and residents is prevalent and permeates the daily lives of neurosurgeons, negatively affecting patient outcomes, career satisfaction, and quality of life. Many neurosurgery programs have instituted wellness programs to combat burnout, but few have published evidence of improvement after implementation. While studies have shown that residents and faculty recognize the importance of wellness and look favorably on such initiatives, very few studies have reported objective outcomes.
A cadaveric precision and accuracy analysis of augmented reality–mediated percutaneous pedicle implant insertion
Authors: Molina Camilo A. , Phillips Frank M. , Colman Matthew W. , Ray Wilson Z. , Khan Majid , Orru’ Emanuele , Poelstra Kornelis , Khoo Larry
Published: October 2020

OBJECTIVE

Augmented reality–mediated spine surgery (ARMSS) is a minimally invasive novel technology that has the potential to increase the efficiency, accuracy, and safety of conventional percutaneous pedicle screw insertion methods. Visual 3D spinal anatomical and 2D navigation images are directly projected onto the operator’s retina and superimposed over the surgical field, eliminating field of vision and attention shift to a remote display. The objective of this cadaveric study was to assess the accuracy and precision of percutaneous ARMSS pedicle implant insertion.

METHODS

Instrumentation was placed in 5 cadaveric torsos via ARMSS with the xvision augmented reality head-mounted display (AR-HMD) platform at levels ranging from T5 to S1 for a total of 113 total implants (93 pedicle screws and 20 Jamshidi needles). Postprocedural CT scans were graded by two independent neuroradiologists using the Gertzbein-Robbins scale (grades A–E) for clinical accuracy. Technical precision was calculated using superimposition analysis employing the Medical Image Interaction Toolkit to yield angular trajectory (°) and linear screw tip (mm) deviation from the virtual pedicle screw position compared with the actual pedicle screw position on postprocedural CT imaging.

RESULTS

The overall implant insertion clinical accuracy achieved was 99.1%. Lumbosacral and thoracic clinical accuracies were 100% and 98.2%, respectively. Specifically, among all implants inserted, 112 were noted to be Gertzbein-Robbins grade A or B (99.12%), with only 1 medial Gertzbein-Robbins grade C breach (> 2-mm pedicle breach) in a thoracic pedicle at T9. Precision analysis of the inserted pedicle screws yielded a mean screw tip linear deviation of 1.98 mm (99% CI 1.74–2.22 mm) and a mean angular error of 1.29° (99% CI 1.11°–1.46°) from the projected trajectory. These data compare favorably with data from existing navigation platforms and regulatory precision requirements mandating that linear and angular deviation be less than 3 mm (p < 0.01) and 3° (p < 0.01), respectively.

CONCLUSIONS

Percutaneous ARMSS pedicle implant insertion is a technically feasible, accurate, and highly precise method.

Published: October 2020

In scientific work it is shown, that our goal is to choose the desired option from variety of alternatives (in our case different options of loading-unloading operations on the vessel) or to take decision which is the best (optimal). Classification in this case is the grounds, as taking the choice is based on choosing certain class, which can be assigned to an alternative. Stratification and rating gives us wide option to make reasonable selection, or to take a kind of decision which will be optimal for the certain moment and occasion. These methods can be used with equal strength at all stages of the processes taking place in the area of current decision making management. This refers to the object of our study of course – solution of selecting optimal option to optimize loading-unloading operation on the vessel.

It goes without saying that variety of alternatives doesn’t have any structure, thus abundance of each element was never structured randomly retrieved or no consideration has been proposed, and they are not a priority and in any order. Coming out of this it’s impossible to mention which alternative is better and which is less desirable. In order to solve the task of selecting a set of alternatives successfully, it is necessary, to make structure of the given abundance of alternatives in any form.

The numerical solution of the boundary value problem was found by the finite difference method and proposed the algorithm for computer implementation. The proposed algorithm may be used for creating software with effective risk assessment strategies and predicting the cleaning and further useful use of the soil massifs.
Sex and Age Effects on Neurobehavioral Toxicity Induced by Binge Alcohol
Authors: Cortez Ibdanelo , Rodgers Shaefali P. , Kosten Therese A. , Leasure J. Leigh
Published: October 2020

Historically, most alcohol neurotoxicity studies were conducted in young adult males and focused on chronic intake. There has been a shift towards studying the effects of alcohol on the adolescent brain, due to alcohol consumption during this formative period disrupting the brain’s developmental trajectory. Because the most typical pattern of adolescent alcohol intake is heavy episodic (binge) drinking, there has also been a shift towards the study of binge alcohol-induced neurobehavioral toxicity. It has thus become apparent that binge alcohol damages the adolescent brain and there is increasing attention to sex-dependent effects. Significant knowledge gaps remain in our understanding of the effects of binge alcohol on the female brain, however. Moreover, it is unsettling that population-level studies indicate that the prevalence of binge drinking is increasing among American women, particularly those in older age groups. Although study of adolescents has made it apparent that binge alcohol disrupts ongoing brain maturational processes, we know almost nothing about how it impacts the aging brain, as studies of its effects on the aged brain are relatively scarce, and the study of sex-dependent effects is just beginning. Given the rapidly increasing population of older Americans, it is crucial that studies address age-dependent effects of binge alcohol, and given the increase in binge drinking in older women who are at higher risk for cognitive decline relative to men, studies must encompass both sexes. Because adolescence and older age are both characterized by age-typical brain changes, and because binge drinking is the most common pattern of alcohol intake in both age groups, the knowledge that we have amassed on binge alcohol effects on the adolescent brain can inform our study of its effects on the aging brain. In this review, we therefore cover the current state of knowledge of sex and age-dependent effects of binge alcohol, as well as statistical and methodological considerations for studies aimed at addressing them.
Proposal of 5-phase 3-degree-of-freedom spherical actuator with auxiliary poles
Authors: Takahara Kazuaki , Hirata Katsuhiro , Niguchi Noboru , Amazutsumi Tomoya
Published: October 2020

Multi-Degree-of-Freedom (multi-DOF) actuating systems are usually composed of several single-DOF motors, which results in large, heavy and complicated structures. In order to solve these problems, various multi-DOF spherical actuators have been actively studied. However, a large number of current phases are required in the spherical actuator. In this paper, in order to reduce the number of current phases, a 3-DOF spherical actuator with auxiliary poles which is driven using 5-phase currents is proposed. Finally, the torque characteristics of the proposed actuator are evaluated through 3-D finite element analysis.

Authors: Xu Bing
Published: October 2020

In the process of e-commerce transactions, a large amount of data will be generated, whose effective classification is one of current research hotspots. An improved feature selection method was proposed based on the characteristics of Bayesian classification algorithm. Due to the long training and testing time of modern large-scale data classification on a single computer, a data classification algorithm based on Naive Bayes was designed and implemented on the Hadoop distributed platform. The experimental results showed that the improved algorithm could effectively improve the accuracy of classification, and the designed parallel Bayesian data classification algorithm had high efficiency, which was suitable for the processing and analysis of massive data.

Authors: Song Chunhuan , Qian Fucai
Published: October 2020

With its unique array arrangement, the detection system radar has both space diversity gain and waveform diversity gain, and is currently recognized as a stealth target buster. The detection system radar is applied to a high-speed moving platform. Using distributed cooperative detection technology, non-coherent fusion detection based on signals can further improve the detection of stealthy targets. Aiming at the high-speed motion radar signal processing algorithm, this paper mainly studies the following three aspects: the first content is the analysis of the waveform characteristics: the basic principles and characteristics of the radar are explained; then the three orthogonal waveforms commonly used in the radar are introduced, including Stepwise frequency division chirp signal, quadrature phase coded signal and mixed-signal; the second content detects radar targets and analyzes the correlation between the scattering coefficients of different radar channels; for scenarios where the scattering coefficients between the channels are non-coherent Introduced two kinds of non-coherent fusion detectors based on generalized likelihood ratio algorithm: centralized detector and double threshold detector; the third content radar multi-target pairing is aimed at the problem of radar multi-target pairing with large inertial navigation error. A multi-target pairing algorithm that uses target delay information and combines the radar’s multi-channel information redundancy characteristics is presented. An expression for judging the correctness of target pairing is derived, and the target pairing steps are given. The relationship between the amount of algorithm operation and the number of radar stations and the number of targets is analyzed in conclusion.

Authors: Wang Yu , Lian Zhengmei , Zou Jihua
Published: October 2020

The main reason that hinders early treatment of ACS patients is delayed patient decision-making (PD). In order to explore the delay factors of patients with ACS, this paper builds a machine learning-based analysis model of delay factors for patients with acute coronary syndrome based on machine learning. Moreover, this paper combines structural equations to analyze the factors affecting accidents, and uses the generalized ordered logit model in statistics and the popular random forest model in machine learning to establish the analysis models of the delay factors of acute coronary syndromes, and analyze the functional structure of the models. In addition, this paper obtains data through actual survey methods, and analyzes the data through the model constructed in this paper to explore the risk factors that affect the delay in seeking medical treatment, which is presented through charts. The research results show that the model constructed in this paper is more reliable and can be applied in practice.

Published: October 2020

This article discusses the design and implementation of a 100 G tunable laser optical module, and briefly introduces the functions of each module in the MCU. The main technologies involve TEC control, wavelength locking, wavelength tuning, and power compensation. By analyzing the traditional positional proportional integral and differential algorithm, improving the proportional integral and differential algorithm, and using the algorithm to achieve wavelength locking, this can prevent the wavelength drift or even the lock due to the overload of the adjustment during the system adjustment process.
A new weighted fuzzy C-means clustering approach considering between-cluster separability
Authors: Wu Ziheng , Li Cong , Zhou Fang , Liu Lei
Published: October 2020

Fuzzy C-means clustering algorithm (FCM) is an effective approach for clustering. However, in most existing FCM type frameworks, only in-cluster compactness is taken into account, whereas the between-cluster separability is overlooked. In this paper, to enhance the clustering, by incorporating the feature weighting and data weighting method, we put forward a new weighted fuzzy C-means clustering approach considering between-cluster separability, in which for achieving good compactness and separability, making the in-cluster distances as small as possible and making the between-cluster distances as large as possible, the in-cluster distances and between-cluster distances are taken into account; To achieve the optimal clustering result, the iterative formulas of the feature weights, membership degrees, data weights and cluster centers are obtained by maximizing the in-cluster compactness and the between-cluster separability. Experiments on real-world datasets were carried out, the results showed that the new approach could obtain promising performance.

Published: October 2020

BACKGROUND: Cortical reorganization between both cerebral hemispheres plays an important role in regaining the affected upper extremity motor function post-stroke. OBJECTIVES: The purpose of the current study was to investigate the recommended number of contra-lesion low frequency repetitive transcranial magnetic stimulation (LF-rTMS) sessions that could enhance cortical reorganization post-stroke. METHODS: Forty patients with right hemiparetic subacute ischemic stroke with an age range between 50–65 yrs were randomly assigned into two equal groups: control (GA) and study (GB) groups. Both groups were treated with a selected physical therapy program for the upper limb. Sham and real contra-lesion LF-rTMS was conducted for both groups daily for two consecutive weeks. Sequential changes of cortical excitability were calculated by the end of each session. RESULTS: The significant enhancement in the cortical excitability was observed at the fourth session in favor of the study group (GB). Sequential rate of change in cortical excitability was significant for the first eight sessions. From the ninth session onwards, no difference could be detected between groups. CONCLUSION: The pattern of recovery after stroke is extensive and not all factors could be controlled. Application of LF-rTMS in conjugation with a selected physical therapy program for the upper limb from four to eight sessions seems to be efficient.
Are epidural corticosteroid injections effective for lumbosacral radicular pain? A Cochrane Review summary with commentary
Authors: Negrini Francesco
Published: October 2020

BACKGROUND: Epidural corticosteroid injection is one of the most common non-surgical procedures for lumbosacral radicular pain. OBJECTIVE: To assess efficacy and safety of epidural corticosteroid injections compared with placebo injections in patients with lumbosacral radicular pain. METHODS: A summary and commentary of a Cochrane Review by Oliveira et al. RESULTS: 25 studies with a total of 2740 participants were included in the review. Moderate quality evidence pointed out a small effect on leg pain at immediate and short-term follow-up and on disability at short-term and intermediate follow-up. Adverse events were not different between corticosteroid and placebo injections. CONCLUSIONS: Epidural corticosteroid injection is slightly more effective than placebo for leg pain and disability at short-term follow up. Clinicians and patients however should be informed of the small effect size of the treatment.
