An investigation of the effects of self-reported self-control strength on shooting performance
Authors: Englert Chris , Dziuba Anna , Wolff Wanja , Giboin Louis-Solal
Published: May 2020

During professional shooting tournaments, which typically last multiple hours, athletes must stay focused at all times in order to perform at their highest levels. Sustaining attention over extended periods of time relies on self-control. Crucially, perceived state self-control strength appears to wane as a function of task duration, which ultimately can impair shooting performance. In the present study, we tested the assumption that the level of self-reported self-control strength decreases over the course of a 1-hour shooting task measured twice during a regular training day and separated by a 2-hour break. Additionally, we assumed that shooting performance would be linked with fluctuations in self-control. A total of 21 shooters (14 elite and 7 sub-elite) took part in this study and were asked to perform a series of 10 shots at a standardized target, five times in the morning and five times in the afternoon (i.e., 100 shots total). The participants also reported their perceived state self-control strength at the baseline (prior to the start of the morning session as well as the afternoon session) and after a series of 10 shots each in the morning and afternoon (i.e., 12 measurements in total). In line with our hypotheses, we observed that perceived state self-control diminished with the number of shots performed, and that perceived state self-control could explain shooting performance. Additionally, these observations could explain the difference in shooting performance between elite and sub-elite athletes. The results suggest that the perception of self-control strength is highly important for optimal shooting performance. Practical implications are discussed.
Working Memory Capacity Predicts Individual Differences in Social Distancing Compliance during the COVID-19 Pandemic in the U.S.
Authors: Xie Weizhen , Campbell Stephen , Zhang Weiwei
Published: May 2020

Noncompliance with social distancing during the early stage of the COVID-19 pandemic poses a great challenge to the public health system. These noncompliance behaviors partly reflect people’s concerns for the inherent costs of social distancing while discounting its public health benefits. We propose that this oversight may be associated with the limitation in one’s mental capacity to simultaneously retain multiple pieces of information in working memory (WM) for rational decision making that leads to social distancing compliance. We tested this hypothesis in 850 U.S. residents during the first 2 weeks following the presidential declaration of national emergency because of the COVID-19 pandemic. We found that participants’ social distancing compliance at this initial stage could be predicted by individual differences in WM capacity, partly due to increased awareness of benefits over costs of social distancing among higher WM capacity individuals. Critically, the unique contribution of WM capacity to the individual differences in social distancing compliance could not be explained by other psychological and socioeconomic factors (e.g., moods, personality, education, and income levels). Furthermore, the critical role of WM capacity in social distancing compliance can be generalized to the compliance with another set of rules for social interactions, namely the fairness norm, in Western cultures. Collectively, our data reveal novel contributions of a core cognitive process underlying social distancing compliance during the early stage of the COVID-19 pandemic, highlighting a potential cognitive venue for developing strategies to mitigate a public health crisis.

Published: May 2020

Many Indian COVID-19 suicide cases are turning the press-media attention and flooding in the social media platforms although, no particular studies assessed the COVID-19 suicide causative factors to a large extent. Therefore, the present study presents 69 COVID-19 suicide cases (aged 19 to 65 years; 63 cases were males). The suicide causalities are included as follows – fear of COVID-19 infection (n=21), followed by financial crisis (n=19), loneliness, social boycott and pressure to be quarantine, COVID-19 positive, COVID-19 work-related stress, unable to come back home due to lockdown, unavailability of alcohol etc. Considering the extreme psychological impacts related to COVID-19, there emerges a need for countrywide extensive tele-mental health care services.

Published: May 2020

Early numeracy is related to preschoolers’ acquisition of skills such as understanding and operating with quantities. Consequently, early numeracy has substantial impact on first Graders’ attainments in typical mathematics. Meta-analysis was conducted to address the extent in which early numeracy interventions are effective. Twenty studies were analyzed, including 3.080 young low-performing children (Ncontrol=1.815, Ntreatment=1.265). The overall best estimate for programs based on Early Numeracy Interventions odds ratio was moderately effective g=0.61 (95% CI=[0.44, 0.78]). Heterogeneity was large. Results of the final meta-regression model predicted larger treatment effects for short-term interventions including 1 to 9 sessions. On average, the interventions included instructional strategies such as Explicit Instruction (g=0.57), Corrective Feedback (g = 0.55), CRA (g =0.64), Concrete Manipulatives (g=0.60) Visual Representations (g=0.57) and one-to-one instructional arrangement g=0.79 are moderately effective for children aged 5-8. Results of the study are discussed with respect to implications for designing early numeracy interventions.
A University Based Social Services Parent Training Model: A Telehealth Adaptation During the COVID-19 Pandemic
Authors: Britwum Kwadwo , Catrone Rocco , Smith G. David , Koch Darwin Shane
Published: May 2020

With the COVID-19 pandemic resulting in social distancing recommendations many service providers find themselves altering the way they must provide medically necessary therapy. Even with the advent of more advanced telehealth technology, implementation of behavioral programming falls mainly on the caregivers of the clients that are served. This crisis brings to question ethical dilemmas and upends the current ways many programs may have been implemented across the world. As a result, a re-evaluation of how these services are delivered is in order. This paper reviews how a University-Based, State-funded Service Delivery Program (USSDP) provided essential and necessary services during the COVID-19 pandemic. Specifically, the purpose of this paper is to describe how the USSDP quickly adopted a telehealth care model in a program that previously had not delivered services in this modality. Ethical, contextual, and competency-based factors are reviewed in the context of this organization followed by a dialogue on broader generalization suggestions utilizing an active support model of care within telehealth restrictions.
Connecting Self-Reported Social Distancing to Real-World Behavior During the COVID-19 Pandemic

Published: May 2020

In an effort to combat COVID-19 and future pandemics, researchers have attempted to identify the factors underlying social distancing. Yet, much of this research relies on self-report measures. In two studies, we examine whether self-reported social distancing predicts objective distancing behavior. In Study 1, individuals’ self-reported social distancing predicted decreased mobility (assessed via smartphone step-counts) during the COVID-19 pandemic. While participants high in self-reported distancing (+1 SD) exhibited a 33% reduction in daily step-count, those low in distancing (-1 SD) exhibited only a 3% reduction. Study 2 extended these findings to the group-level. Self-reported social distancing at the U.S. state level accounted for 20% of the variance in states’ objective reduction in overall movement and visiting nonessential services (calculated via the GPS coordinates of ~15 million people). Collectively, our results indicate that self-reported social distancing tracks actual social distancing behavior.
The Dutch Auditory & Image Vocabulary Test (DAIVT): A New Dutch Receptive Vocabulary Test for Students
Authors: Bousard Ibrich , Brysbaert Marc
Published: May 2020

We introduce a new Dutch receptive vocabulary test, the Dutch auditory & image vocabulary test (DAIVT). The test is multiple choice and assesses vocabulary knowledge for spoken words. The measure has an online format, has free access, and allows easy data collection. The test was developed with the intent to enable testing for research purposes with university students. This paper describes the test construction. We cover three phases: 1) collecting stimulus materials and developing the test’s first version, 2) an exploratory item-analysis on the first draft (n= 93), and 3) validating the test (both the second and the final version) by comparing it to two existing tests (n= 270, n= 157). The results indicate that the test is reliable and correlates well with existing Dutch receptive vocabulary tests (convergent validity). The final version of the DAIVT comprises 90 test items and 1 practice item. It can be used freely for research purposes.

Published: May 2020

BACKGROUND: Comorbidity between obsessive compulsive disorder (OCD) and psychotic disorders has long been a subject of interest and speculation, with much overlap being reported. The current review seeks to: (1) Investigate the prevalence of co-occurring OCD and psychosis, reporting pooled prevalence rates; and (2) Explore variability in reported rates on the basis of categorical and/or dimensional classifications of OCD and psychosis and (3) explore potential moderators of variability. METHOD: A systematic search was performed of key databases (Embase, PSYCHInfo, MEDLINE, Scopus) from January 1988 to October 2017. Included in the meta-analyses were studies that reported adult (18+) prevalence of comorbid OCD, obsessional compulsive symptoms (OCS) and psychosis-related disorders. RESULTS: 94 articles with 103 effect sizes were extracted. Overall, when using categorical diagnoses the prevalence rate of comorbid OCD and psychotic disorder was 12% (n=155649; k= 81; 95% CI=9-15%). Using diagnostic plus symptom criteria, the prevalence was 24% (n=9563; k = 46, 95% CI=20-28%).CONCLUSION: Given the substantial co-occurrence, it is important that individuals presenting in routine clinical practice are assessed for both disorders. To advance understanding, future research must go beyond comorbidity to explore latent dimensions that may account for their development and/or maintenance (e.g., trauma).

Published: May 2020

Objectives. This study aimed to understand the relationship between resource gains and losses, coping, and quality of life during the growth phase of the COVID-19 pandemic.Material and Methods. The Internet-based survey covered 353 individuals who had participated in a psychological support project operated by one of the non-governmental organisations in Lublin, Poland, in the 12 months prior to the outbreak of the pandemic. The questionnaire used in the study contained questions to collect sociodemographic data and psychometric scales to measure resource gains and losses (Conservation of Resources – Evaluation), quality of life (World Health Organization [WHO] Quality of Life-BREF), and strategies of coping with the pandemic situation (modified Brief Cope).Results. Higher global quality of life occurred with higher gains and minor losses, as well as with coping through planning, positive reframing, emotional support seeking, reduced substance use tendency, low self-blame, avoidance, and disengagement. Moreover, helplessness-based coping strategies were found to mediate both the relationship between resource gains and quality of life and between resource loss and quality of life.Conclusions. Factors that may reduce people’s quality of life during the COVID-19 pandemic are an increase in losses and limited gains, experienced over the six months preceding the pandemic, as well as not using active, meaning-oriented, and support-seeking coping strategies, but using avoidance behaviours instead. Coping strategies specific to people experiencing helplessness are a mediating mechanism between losses and limited gains of resources and quality of life.

Personal transformation and advance directives: an experimental bioethics approach
Authors: Earp Brian D. , Latham Stephen R. , Tobia Kevin
Published: May 2020

Some people with dementia are transformed by the disease, to the point that family members may describe them as a “different person.” These transformations may be negative or positive. What factors affect the judgements of ordinary people about whether an advance directive (AD) should be followed in such cases? We conducted three studies to test the influence of (1) positive versus negative transformation and (2) “treat” versus “withhold treatment” AD on the judgements of US participants (n = 1676) as to whether the AD should be followed and the extent to which the late-stage dementia patient had become a different person. We found that participants generally endorsed following the AD, irrespective of condition, but much less so when the patient had a positive transformation. Participants also favored “treat” over “withhold treatment” ADs. Unexpectedly, we found that AD type affected “different person” judgments: participants registered significantly weaker agreement with the proposition that the patient had become a different person when the AD instructed treatment. We discuss these results in the context of Walsh’s (2020) newly proposed normative model for AD decision-making.

A comprehensive analysis of the journal evaluation system in China
Authors: HUANG Ying , LI Ruinan , Zhang Lin , Sivertsen Gunnar
Published: May 2020

Journal evaluation systems are important in science because they focus on the quality of how new results are critically reviewed and published. They are also important because the prestige and scientific impact of journals is given attention in research assessment and in career and funding systems. Journal evaluation has become increasingly important in China with the expansion of the country’s research and innovation system and its rise as a major contributor to global science. In this paper, we first describe the history and background for journal evaluation in China. Then, we systematically introduce and compare the most influential journal lists and indexing services in China. These are: the Chinese Science Citation Database (CSCD); the journal partition table (JPT); the AMI Comprehensive Evaluation Report (AMI); the Chinese STM Citation Report (CJCR); the “A Guide to the Core Journals of China” (GCJC); the Chinese Social Sciences Citation Index (CSSCI); and the World Academic Journal Clout Index (WAJCI). Some other lists published by government agencies, professional associations, and universities are briefly introduced as well. Thereby, the tradition and landscape of the journal evaluation system in China is comprehensively covered. Methods and practices are closely described and sometimes compared to how other countries assess and rank journals.
Social Communication Across the Lifespan: The Influence of Empathy
Authors: Rothermich Kathrin
Published: May 2020

Studies testing the effects of aging on social communication have mainly focused on one sensory modality, for example using written vignettes. In the current study, we examine the effect of healthy aging, empathy, and anxiety traits on a social communication task using video stimuli that reflect real-world interactions. By means of an online recruitment platform, we asked young, middle-aged, and older adults between the ages 18 and 76 (N=100) to evaluate videos of actors using different forms of literal and nonliteral language, such as sarcasm or teasing. The participants’ task was to infer the speakers’ belief and the speaker’s intention, and we also collected data on self-reported social anxiety levels and empathy. Older participants demonstrated lower accuracy in discriminating nonliteral from literal interactions compared to younger and middle-aged groups, while older adults with higher perspective-taking scores were more accurate at identifying teasing as nonliteral. This effect was partially mediated by empathy. When evaluating speaker intentions, older adults judged sarcasm as friendlier compared to literal negative utterances. Our results expand on age-related similarities and differences in evaluating speaker intentions and we discuss our results in the context of the Tinge Hypothesis.
Atoms, quanta, and qubits: Atomism in quantum mechanics and information
Authors: Penchev Vasil Dinev
Published: May 2020

The original conception of atomism suggests “atoms”, which cannot be divided more into composing parts. However, the name “atom” in physics is reserved for entities, which can be divided into electrons, protons, neutrons and other “elementary particles”, some of which are in turn compounded by other, “more elementary” ones. Instead of this, quantum mechanics is grounded on the actually indivisible quanta of action limited by the fundamental Planck constant. It resolves the problem of how both discrete and continuous (even smooth) to be described uniformly and invariantly in thus. Quantum mechanics can be interpreted in terms of quantum information. Qubit is the indivisible unit (“atom”) of quantum information. The imagery of atomism in modern physics moves from atoms of matter (or energy) via “atoms” (quanta) of action to “atoms” (qubits) of quantum information. This is a conceptual shift in the cognition of reality to terms of information, choice, and time.
Warfare, Ethics, Ethology: evolutionary fundamentals for conflict and cooperation
Authors: Barreiros Daniel
Published: May 2020

The aim of this article is to set a macro-historical narrative concerning the emergence of warfare and social ethics as symplesiomorphic features in the lineage of Homo sapiens. This means that these two behavioral aspects, representative of a very selected branch in the phylogenetic tree of the Primate order, are shared by the two lineages of great African apes that diverged from a common ancestor around six million years in the past, leading to extant humans and chimpanzees. Therefore, this article proposes an ethological understanding of warfare and social ethics, as both are innate to the social high-specialized modular mind present in the species of genera Pan and Homo. However behavioral restraints to intersocietal coalitionary violence seems to be an exclusive aspect of the transdominial modular cognition that characterizes modern humans. Thus, if in the evolutionary long durée, warfare and restrictions to intrasocial violence both appear to be ethologically common to humans and chimpanzees to a certain extent, an ethics of warfare - and, of course, the cognitive capability for intersocietal peace - seems to be distinctly human.
From the “Free Will Theorems” to the “Choice Ontology” of Quantum Mechanics
Authors: Penchev Vasil Dinev
Published: May 2020

If the concept of “free will” is reduced to that of “choice” all physical world share the latter quality. Anyway the “free will” can be distinguished from the “choice”: The “free will” involves implicitly certain preliminary goal, and the choice is only the mean, by which it can be achieved or not by the one who determines the goal. Thus, for example, an electron has always a choice but not free will unlike a human possessing both. Consequently, and paradoxically, the determinism of classical physics is more subjective and more anthropomorphic than the indeterminism of quantum mechanics for the former presupposes certain deterministic goal implicitly following the model of human freewill behavior.The choice is usually linked to very complicated systems such as human brain or society and even often associated with consciousness. In its background, the material world is deterministic and absolutely devoid of choice. However, quantum mechanics introduces the choice in the fundament of physical world, in the only way, in which it can exist: All exists in the “phase transition” of the present between the uncertain future and the well-ordered past. Thus the present is forced to choose in order to be able to transform the coherent state of future into the well-ordering of past. The concept of choice as if suggests that there is one who chooses. However quantum mechanics involves a generalized case of choice, which can be called “subjectless”: There is certain choice, which originates from the transition of the future into the past. Thus that kind of choice is shared of all existing and does not need any subject: It can be considered as a low of nature.There are a few theorems in quantum mechanics directly relevant to the topic: two of them are called “free will theorems” by their authors, Conway and Kochen, and according to them: “Do we really have free will, or, as a few determined folk maintain, is it all an illusion? We don’t know, but will prove in this paper that if indeed there exist any experimenters with a modicum of free will, then elementary particles must have their own share of this valuable commodity” “The import of the free will theorem is that it is not only current quantum theory, but the world itself that is non-deterministic, so that no future theory can return us to a clockwork universe”Those theorems can be considered as a continuation of the so-called theorems about the absence of “hidden variables” in quantum mechanics.
Two strategies to finity: completeness and incompleteness. The completeness of quantum mechanics
Authors: Penchev Vasil Dinev
Published: May 2020

Two strategies to infinity are equally relevant for it is as universal and thus complete as open and thus incomplete. Quantum mechanics is forced to introduce infinity implicitly by Hilbert space, on which is founded its formalism. One can demonstrate that essential properties of quantum information, entanglement, and quantum computer originate directly from infinity once it is involved in quantum mechanics. Thus, thеse phenomena can be elucidated as both complete and incomplete, after which choice is the border between them. A special kind of invariance to the axiom of choice shared by quantum mechanics is discussed to be involved that border between the completeness and incompleteness of infinity in a consistent way. The so-called paradox of Albert Einstein, Boris Podolsky, and Nathan Rosen is interpreted entirely in the same terms only of set theory. Quantum computer can demonstrate especially clearly the privilege of the internal position, or “observer”, or “user” to infinity implied by Henkin’s proposition as the only consistent ones as to infinity.
Magnitude Based Inference in Relation to One-sided Hypotheses Testing Procedures
Authors: Aisbett Janet , Lakens Daniel , Sainani Kristin
Published: May 2020

Magnitude based inference (MBI) was widely adopted by sport science researchers as an alternative to null hypothesis significance tests. It has been criticized for lacking a theoretical framework, mixing Bayesian and frequentist thinking, and encouraging researchers to run small studies with high Type 1 error rates. MBI terminology describes the position of confidence intervals in relation to smallest meaningful effect sizes. We show these positions correspond to combinations of one-sided tests of hypotheses about the presence or absence of meaningful effects, and formally describe MBI as a multiple decision procedure. MBI terminology operates as if tests are conducted at multiple alpha levels. We illustrate how error rates can be controlled by limiting each one-sided hypothesis test to a single alpha level. To provide transparent error control in a Neyman-Pearson framework and encourage the use of standard statistical software, we recommend replacing MBI with one-sided tests against smallest meaningful effects, or pairs of such tests as in equivalence testing. Researchers should pre-specify their hypotheses and alpha levels, perform a priori sample size calculations, and justify all assumptions. Our recommendations show researchers what tests to use and how to design and report their statistical analyses to accord with standard frequentist practice.
Clinicopathological study of gall bladder carcinoma: Our experience from Patan Hospital, Patan Academy of Health Sciences
Authors: Paudyal Sanjaya , K.C. Shiva Raj , Maharjan Shanta Bir , Shah Surendra , Giri Niraj
Published: May 2020

Introduction: Gall bladder carcinoma is not a common disease. The overall prevalence is low worldwide. It is a highly malignant tumor with a poor prognosis. The outcome of gallbladder carcinoma is poor, and the overall 5-year survival rate is less than 5%. The carcinoma gall bladder is 2-6 times more common in females compared to males and its incidence increases with increasing age. Aggressive surgical management and preoperative adjuvant therapy have helped to prolong survival in patients with gallbladder cancer. We conducted a study with an aim to evaluate the clinicopathological aspect of the disease in patients of gall bladder cancer managed in our surgical department.

Methods: Data were recorded retrospectively by reviewing the charts of the patients who were diagnosed and treated for carcinoma gall bladder in Patan hospital from Aug 2017 to Aug 2019.

Results: Thirty patients were included in the study. Twenty (66.7%) were female and ten (33.33%) were males. Age ranged from 36 to 83 years with the median age of presentation at 63.5 yrs. Curative treatment was possible in 43.33% of the patients, among them 12 had radical surgery and one had cholecystectomy alone for the T1a stage.  All other (56.6%) required palliative treatment. One patient developed liver metastasis within six months of radical excision.

Conclusions: The majority of the patients present with an advanced disease which makes it less chance for curative surgical resection. Since only palliative care is possible in an advanced stage, early detection and curative treatment are advisable.
Transarterial embolization in management of post-traumatic hematuria
Authors: Chataut Dinesh , Suwal Sundar , Thapa Ajit , Chaudh Ranjit , Ghimire Ram Kumar
Published: May 2020

Introduction: Iatrogenic injuries are the most common (>50%) cause of renal vascular lesions and most of these vascular lesions resolve spontaneously, however, surgical or percutaneous treatment is recommended when there is massive bleeding, renal hemorrhage persisting for more than 72 hours, or progressively deteriorating renal functions. Renal artery embolization is considered safe, effective as well as less invasive as the alternative treatment method is emergent nephrectomy or clamping of the renal artery which results in the loss of the kidney. We conducted a study to describe the efficacy of transarterial embolization in the management of post-traumatic hematuria.

Methods: Retrospective review of 30 patients from April 2013 to July 2017 who underwent transarterial embolization for renal vascular lesions following blunt and iatrogenic renal injuries was done. Type of renal vascular lesions, the angiographic status of visualized vascular lesions immediately following embolization, and post-procedural status of hematuria were evaluated.

Results: Thirty patients with a mean age of 35.3 years were included in the study.  Twenty-two patients with pseudoaneurysm and eight with arteriovenous fistula in the kidney underwent transarterial embolization. Selective embolization was done in 28 out of 30 patients with complete resolution of hematuria. Two patients underwent non-selective embolization of the main renal artery which was necessary for control of hematuria.  

Conclusions: Transarterial embolization is a highly effective technique in the management of traumatic renal vascular lesions presenting with left threatening or continuous hematuria.

A great asset of our time is a significant increase in life expectancy. This is especially true for women’s health issues, as women live longer than men and are more stubbornly opposed to age-related changes and aging, trying to preserve not only beauty and youth, but also reproductive function. The use of algorithms and mathematical models for predicting the occurrence of pathology in medical practice makes it possible to predict in advance not only the fact of the occurrence of this complication, but also to determine the likelihood of its occurrence, which is very important for the subsequent identification of risk groups in order to develop individualized preventive and treatment measures. Namely, the timely appointment of preventive measures and the development of individual treatment programs will improve the quality of life of every woman. The purpose of the work is to develop an algorithm and a mathematical model for predicting the risk of developing early climax (EC) against the background of a woman’s biological aging by studying various factors with the subsequent development of individualized preventive and treatment measures. In order to study the possibilities of predicting the occurrence of RK against the background of a woman’s biological aging, a retrospective analysis of the frequency of the studied factors in patients with EC was carried out in comparison with women with preserved menstrual function and timely onset of menopause. The method of step-by-step discriminant analysis was used as a mathematical model, which made it possible to identify the probability of a difference between the comparison groups by the F value of Fisher statistics, to develop a forecast algorithm and conduct mathematical modeling. 12 out of 145 factors were identified by discriminant analysis, which most influenced the occurrence of this pathology, including the following: early menopause in relatives, smoking, history of artificial abortion (more than 3), extragenital pathology; the presence of stressful situations at home, at work; surgery on the uterus and appendages; inadequate physical and mental activity; adiposity; low serum estradiol concentrations; high levels of follicle-stimulating hormone in serum; anti-Mullerian serum hormone levels below normal and more than three in vitro fertilization attempts. It is the method of multivariate mathematical analysis, considering all the most informative factors and variants of their expression, made it possible to create this prognostic model. The algorithm and mathematical model developed by the authors to predict the occurrence of this pathology, considering certain factors, have a high sensitivity and informativeness, which makes it possible to identify the risk groups of patients of reproductive age in the occurrence of this pathology in order to prevent and prescribe individual treatment in a timely manner.

The article presents and analyzes data from an experimental study conducted on white rats in females and males of reproductive age. The purpose of the study to study the morphometric and histological changes in the parenchyma of the lymph nodes of rats under the high-calorie diet (HCD) and with the correction of melatonin. The study was performed on 80 white rats of reproductive age. Microanatomy of the structural components of lymph nodes of white rats under physiological norms was examined in 10 intact animals. Experimental animals are divided into 5 groups. Statistical processing of digital data was performed using “Excel” software and “STATISTICA 6.0” using the parametric method. Eight weeks after HCD, there was a significant decrease in the relative area of the cortical substance in the parenchyma of lymph nodes of white rats of males and females by 10.3 % and 8.3 %, respectively, and an increase in the relative area of the medullary substance by 16.1 % and 13.2 %, respectively, greater than the intact animal group parameter. Corticomedullary index (CMI) decreased by 22.9 % and 19.0 %. After six weeks of HCD and the next six weeks of standard vivarium diet and melatonin administration, the relative area of cortical substance in the parenchyma of lymph nodes of white rats in males and females was 2.0 % and 2.9 %, respectively, greater than the parameters of the intact group of animals. Accordingly, the relative area of the medullary substance is 3.1 % and 4.6 % less than the parameters of the intact group of animals. CMI in both male and male rats was 5.1 % and 7.6 %, respectively, greater than the intact animal group parameter. Under the conditions of melatonin correction, it was found that on the histological preparations of lymph nodes the vein and artery were full-blooded. Empty hemocapillaries with thickened wall are observed. In the paracortical region, the number of high endothelial capillary venules decreases. Thus, long-term administration of melatonin improves the morphometric parameters of the parenchyma of the lymph nodes of rats, restores the morphological structure of the organ.

Today, the role of the traumatic factor and inflammation in the development and progression of osteoarthrosis is generally recognized, but the available research results do not allow to establish the role of impaired biomechanics as a monofactor in the development of deforming ostearthrosis of the shoulder joint. Violation of the function of the bone and bone-cartilage elements of the joint, which is compensated by soft tissue formations, leads to overloads of the joints, upsets the normal balance of the load forces in the joint, creates abnormal biomechanics and the resulting pathological manifestations of deforming osteoarthrosis. The aim of the study is research of the dynamics of the disturbed biomechanics influence of the shoulder joint on the development of deformation osteoarthrosis and the features of the development of its structural changes. The experiments were conducted on guinea pigs weighing 380-420 grams at the age of 5 months. A model of surgical restriction of joint mobility was reproduced, which caused the formation of contracture. Using the methods of histology and scanning electron microscopy, we studied the relief of the articular surface, the topography of degenerative changes, and structural changes in the articular cartilage and subchondral bone. A statistical evaluation of the obtained data samples was carried out using Student t-test. The results were considered reliable at р<0.05. The results of an experimental study demonstrated a decrease in the thickness and structure of articular cartilage when modeling deforming osteoarthrosis and confirmed the hypothesis that pathological limitation of the mobility of the shoulder joint and violation of biomechanics is an independent factor in the formation of osteoarthrosis. After surgery on day 30, degenerative changes and their progression with the formation of contracture on day 90 of observation were found in the articular cartilage. The features of the development of articular surface degeneration, the dynamics of the pathological changes and topography, which can expand the understanding of the pathogenesis of the disease, were established. The loss of the superficial zone caused the progression of dystrophic changes in the articular cartilage and sclerosis of the subchondral bone at 60 and 90 days.

One of the most effective anticancer drugs for breast cancer, lymphoma, soft tissue sarcoma, leukemia, some solid tumors is Doxorubicin. However, its antitumor effect directly correlates with the dose-dependent manifestation of toxicity to healthy tissues and body systems. The purpose of the study is to study the dynamics of ultrastructural changes of the hemomicrocirculatory bed under the influence of Doxorubicin. Animals were divided into 3 groups: I – intact rats (n=10); II – control (n=20); III – rats with Doxorubicin model (n=40). Doxorubicin was administered intraperitoneally at a dose of 5 mg/kg body weight once a week for 4 weeks. An animal control group was intraperitoneally injected with an equivalent volume of saline. Pulmonary tissue sampling for electron microscopic examination was performed under thiopental anesthesia 7, 14, 21, 28 days after the start of the experiment. Pieces of pulmonary tissue were fixed in 2.5% glutaraldehyde followed by fixation in 1% osmium tetroxide. After dehydration, the material was poured into araldite-epon. The sections obtained on a “Tesla BS-490” ultramicrotome were examined in an electron microscope “PEM-125K”. It is established that within 7 days after the first injection of Doxorubicin in the lungs changes in the structural organization of the hemomicrocapillary bed and the disturbance of blood rheological properties are determined, as evidenced by the excessive accumulation of neutrophils in the hemocapillaries, their adhesion and aggregation. With the extension of the study period (14-28 days) there is a progressive disturbance of the submicroscopic structure of hemocapillaries of the alveolar wall and marked changes in the rheological properties of blood. In endothelial cells, swelling phenomena with organelle disorganization are determined, and in some areas there is a desquamation of endothelial cells into the lumen of the hemocapillaries with basal membrane exposures. In the lumen of the microvessels, red blood cells and leuco-platelet aggregates are noted. Thus, the introduction of Doxorubicin leads to pronounced submicroscopic changes in the hemomicrocirculatory bed. Violation of the ultrastructural organization of the hemomicrocirculatory bed of the lungs is determined after 7 days after the start of the study.
