Abstract
After being extensively explored, observations and theories have shown that satellites are preferentially aligned with major axes of their host centrals. There are still some unresolved issues on this topic. In this paper, we present studies on satellite spatial distribution. To fairly compare with observations, we develop a novel galaxy finder and reconstruction algorithm in hydrodynamical simulation, which is based on the projected mock image, taking into account the full consideration of the point-spread function, pixel size, surface brightness limit, resolution, and redshift dimming effects. With galaxy samples constructed using such an algorithm, the satellite alignment is examined by comparing with observational results. It is found that the observational alignment can be reproduced for red galaxies, which dominate the sample in this study, but not for blue galaxies. Satellites’ radial distribution is also investigated. It exhibits that outer satellites within host halos show stronger alignment signal than satellites in the inner regions, especially for red satellites, which is in contrast with previous studies. The disagreement is mainly due to extra galaxies identified by our new galaxy finder, which are mainly located in the inner region of host halos. Our study illustrates that at lower redshift, the alignment strength becomes stronger, while the radial distribution curve becomes flatter. This suggests differences in the evolution of the angular distribution between satellites residing in the inner and outer halos and implies that the post-infall evolution reduces the original alignment signal and that the impact decreases for satellites with later infall times.

Abstract
We examined two decades of SpeX/NASA Infrared Telescope Facility observations from the Small Main-Belt Asteroid Spectroscopic Survey (SMASS) and the MIT–Hawaii Near-Earth Object Spectroscopic Survey (MITHNEOS) to investigate uncertainties and systematic errors in reflectance spectral slope measurements of asteroids. From 628 spectra of 11 solar analogs used for calibration of the asteroid spectra, we derived an uncertainty of

on slope measurements over 0.8–2.4 μm. Air mass contributes to −0.92% μm−1 per 0.1 unit air mass difference between the asteroid and the solar analog and therefore for an overall 2.8% μm−1 slope variability in SMASS and MITHNEOS designed to operate within 1.0–1.3 air mass. No additional observing conditions (including the parallactic angle, seeing, and humidity) were found to contribute systematically to slope change. We discuss implications for asteroid taxonomic classification works. Uncertainties provided in this study should be accounted for in future compositional investigation of small bodies to distinguish intrinsic heterogeneities from possible instrumental effects.
Gratitude is female. Biological sex, socio-cultural gender versus gratitude and positive orientation
Authors: Skalski Sebastian , Pochwatko Grzegorz 
Published: April 2020

BackgroundAccording to previous studies, women experience emotions more frequently and intensively than men, and also reveal greater sensitivity to emotions of other people. Relationships turn out to be more complicated in the case of socio-cultural gender. The objective of the study was to search for relations between biological sex, socio-cultural gender, gratitude and positive orientation.Participants and procedureThe study involved 238 participants (125 women and 113 men). The average age of the participants was 33.28 (SD = 8.95). The following research tools were employed: the Masculinity and Femininity Scale, the Gratitude Questionnaire and the Positivity Scale. To determine the significance of differences, Student’s t-test and analy-sis of variance (ANOVA) were used. In order to establish the relationships between variables, Pearson’s corre-lation coefficient and linear regression were applied. The significance of the mediation model was tested using Sobel’s test.ResultsBiological sex and socio-cultural gender differentiated the results of gratitude. Femininity was associated with higher scores on the scales of gratitude and positive orientation. Gratitude showed a correlation with positive orientation.ConclusionsWomen exhibit a higher level of gratitude than men. Androgynous people show a higher level of gratitude than people who are sex-typed, undifferentiated and cross-sex-typed. Sex-typed women show a higher level of gratitude compared to sex-typed men. Women who are cross-sex-typed display a lower level of gratitude than cross-sex-typed men. Gratitude is a mediator of the relationship between femininity and positive orientation.

BackgroundPrevious studies indicate that being in a relationship has a beneficial effect on the physical and mental health and also significantly affects the quality of life. One of the essential elements of the relationship is intimacy, which includes sharing experiences, support and mutual understanding, as well as respect and care for the good of the partner. Being in a relationship, the nature of this relationship (marriage vs. informal relationship) as well as the level of intimacy and the assessment of the quality of the relationship may be in relation to the personal sense of well-being. In this research we intended to estimate the significance of these variables for the sense of well-being and analyze which of these variables have the same meaning for the sense of well-being of young women and men.Participants and procedureThe sample consisted of 431 people (217 women and 214 men) aged 23 to 37 years (46% of the study group were people in relationships, and 54% were single).ResultsThe conducted research confirmed the relationship between the sense of eudaimonic well-being and having a partner, as well as the relationship between sense of intimacy with the partner and the assessment of the quality of the relationship, indicating some differences in this respect between women and men.ConclusionsIt seems that an important issue, worth investigating in our research, concerns the reasons why individuals live a single life (voluntary and involuntary singles), and whether or not they are satisfied with this kind of life. Just as in the case of relationships it is not only the fact of being in a relationship that makes a difference but the level of satisfaction with the relationship as well, also in the case of singles satisfaction (or dissatisfaction) with living alone may prove to be significant.

PurposeThe management of patients with disorders of consciousness (DOC) constitutes a challenge for clinicians.Case reportWe present the case of a 66-year-old man who developed coma with subsequent DOC after a severe traumatic brain injury. Behavioural assessment constitutes the gold standard in the evaluation of patients with DOC. In the case presented herein the neuropsychological findings were ambiguous, and the patient underwent functional magnetic resonance imaging (fMRI) to determine whether he was in a vegetative state or minimally conscious state. Three paradigms: passive, active, and resting state fMRI were used to study the brain activity in our patient.ConclusionsfMRI provided reliable evidence of preserved minimal consciousness. The neuroimaging techniques used in our patient were vital for his further treatment.

PurposeIdentification of the group of patients meeting the criteria of a severe multiple trauma (polytrauma) among those admitted to the regional trauma centre and subjected to whole-body computed tomography (WBCT) due to injuries. Identification the patients for whom WBCT was the optimal choice.Material and methodsRetrospective analysis of the data of 303 patients undergoing WBCT in the period 2015-2017 with assessment of the injury severity based on the abbreviated injury scale (AIS) and injury severity score (ISS).ResultsAmong 303 patients undergoing WBCT due to trauma, multiple injuries with ISS > 15 were found in 74 individuals (24.4%). After excluding patients whose limb fractures increased ISS above 15, the group decreased to 63 patients (20.8%). For these patients, the WBCT may be described as the optimal imaging method at an early stage of management.ConclusionsTrauma patients are too often qualified for WBCT. Exposure to a high dose of ionising radiation associated with this modality requires critical analysis of the scope of indications and rules of conduct for trauma teams.

PurposeTo plan a treatment strategy for a spinal arteriovenous shunt (SAVS), identifying the artery of Adamkiewicz (AKA) and its origin is indispensable. However, detecting the AKA is very difficult in patients with an SAVS when using computed tomography angiography (CTA) by the usual method to find the hairpin curved artery because dilated drainage veins nearly always coexist with the hairpin curved AKA. We designed a method to identify the AKA by focusing on the diameter and pathway of the anterior radiculomedullary arteries (RMAs).Material and methodsSeven consecutive patients with an SAVS were surveyed. They underwent contrast-enhanced CTA and conventional angiography from January 2009 to December 2012. Two readers evaluated the CTA images and assumed that the AKA was the artery that ran through the anterior portion of the neural foramen and continued to pass on the ventral side of the spinal cord.ResultsAmong the seven patients, nine AKAs were detected with conventional angiography. When using our method, seven AKAs and six AKAs were identified on CTA by Reader 1 and Reader 2, respectively. The average sensitivity was 72.3%, and the specificity, accuracy, positive predictive value, and negative predictive value were sufficiently high (i.e. > 85%) for both readers. The kappa value for detecting the AKA was 0.98.ConclusionsDetecting the origin of the AKA with CTA is challenging in patients with an SAVS. However, focusing on the diameter and pathway of the RMAs may allow successful identification.

ObjectivesSpecific systemic autoimmune syndrome characterized by inflammatory myopathy, arthritis or arthralgias, interstitial lung disease (ILD), fever, Raynaud’s phenomenon, and mechanic’s hands is called antisynthetase syndrome (AS). The aim of this study was to assess the clinical spectrum associated with presence of aminoacyl-transfer RNA synthetase autoantibodies (ASA).Material and methodsA total of 305 patients with presence of myositis-specific autoantibodies were identified in the database of immunological tests performed in the Clinical Immunology and Transplantology Unit, Medical University of Gdansk between January 2011 and March 2016. In 110 patients (36%) ASA were detected. The detailed analysis included 50 patients with ASA for whom full clinical data were available.ResultsThe incidence of specific ASA in the analyzed group was: Jo-1 46% (23 patients), PL-12 32% (16 patients), PL-7 16% (8 patients), OJ 12% (6 patients), EJ 6% (3 patients). In 10% (5 patients) there was coexistence of at least one ASA, and in another 5 patients there was coexistence of ASA with other antibodies specific for myositis (MSA). In the analyzed group of patients 11 (22%) satisfied the Bohan and Peter criteria for dermatomyositis, 1 for polymyositis. In 5 patients (10%) based on clinical presentation and ASA presence the AS was recognized. Another 3 patients met the criteria of the overlap syndrome polymyositis respectively with systemic lupus, rheumatoid arthritis, and scleroderma. In 5 patients undifferentiated connective tissue disease was diagnosed, and 14 consecutive patients were diagnosed with other connective tissue diseases, while 12 patients did not receive a definitive diagnosis.ConclusionsThe clinical presentation of patients with the presence of ASA is varied. Their presence indicates not only idiopathic inflammatory myopathies, but also non-specifically other disease entities. These patients require observation for the development of idiopathic inflammatory myopathy, and ILD.

ObjectivesThe introduction of vaccinations against viral hepatitis B in the years 1994–1996 in Poland significantly improved the epidemiological situation of hepatitis B virus (HBV) infections in our country. According to the report of the National Institute of Public Health – National Institute of Hygiene in 2018, 40 cases of acute hepatitis B were noted while still in the 1980s between 10 and 20 thousand new cases were reported annually. The aim of the study was to determine whether in children treated with biological drugs (adalimumab, etanercept, infliximab) due to juvenile idiopathic arthritis (JIA), vaccinated against hepatitis B in infancy, a protective concentration of anti-HBs antibodies persists. In patients, the value ≥ 10 mIU/ml is regarded as a protective concentration of antibodies, determined at least four weeks after administration of the last vaccine dose. Among healthy individuals, presence of anti-HBs antibodies in any concentration means seroprotection. No booster vaccinations are recommended in basically vaccinated healthy individuals.Material and methodsThe concentrations of anti-HBs antibodies were determined in 56 children with JIA (38 girls – 67.9% and 18 boys – 32.1%) aged from 2 years and 4 months to 17.5 years, treated for at least three months with biological drugs. The diagnosis of JIA was made based on the International League of Associations for Rheumatology (ILAR) criteria. All studied patients were at the stable stage of the disease and received a full course of hepatitis B vaccination during infancy (in accordance with 0,1,6 months injection scheme).ResultsIn the studied children a protective anti-HBs antibody concentration was found in 34 cases (60.7%), and 22 children (39.3%) had anti-HBs antibody concentration < 10 mIU/ml (in these children no seroprotection was found).ConclusionsThe post-vaccination antibody concentration should be determined in children with JIA, treated with biological drugs and, in case of absence of a protective concentration, revaccination should be started.

Authors: Boyarchuk Oksana 
Published: April 2020

ObjectivesHeritable disorders of connective tissue (HDCT) are associated with morphological and functional disorders of different organs and systems. The aim of our study was to determine the clinical signs of heritable disorders of connective tissue and oxyproline levels in children with acute rheumatic fever (ARF) and rheumatic heart disease (RHD).Material and methodsA total of 155 patients aged 4 to 17 years participated in the study: 23 with ARF, 78 with RHD, and 54 healthy patients with a history of ARF. All patients underwent a standardized examination protocol, which consisted of a detailed medical history recorded by the physician, general and special laboratory tests, electrocardiogram, echocardiography, and Doppler echocardiography. Special attention was paid to the clinical signs of HDCT. The intensity of the metabolic processes in the connective tissue was evaluated by serum oxyproline levels.ResultsThe signs of HDCT were revealed in 121 (78.1%) of the patients with ARF and RHD. Among cardiovascular manifestations, we observed mitral valve prolapse most often – in 91 (58.7%) patients. Musculoskeletal anomalies were observed in 94 (60.7%) patients. Both groups of patients with ARF and RHD had elevated mean serum oxyproline levels.ConclusionsChildren with acute rheumatic fever and rheumatic heart disease presented with a number of signs characteristic of heritable connective tissue disorders. The cardiovascular and musculoskeletal system changes are the most frequent among all features of HDCT. Elevated levels of serum oxyproline in patients with ARF and RHD confirm connective tissue disorders. Children with manifestations of HDCT are at the risk of ARF and RHD development.

Authors: Kwiatkowska Brygida , Maślińska Maria 
Published: April 2020

Eating habits have been analysed for years as a factor influencing the development of autoimmune diseases and susceptibility to infections. On the basis of research, observational studies and meta-analyses, special attention was paid to omega-3 and omega-6 acids. The purpose of the review is to show the importance of omega-3 and omega-6 acids as important ingredients in the healthy diet and as factors protecting against the development of the most common inflammatory rheumatic diseases. The influence of these omega-3 and -6 acids on the course of rheumatic diseases and arguments for their use as complementary therapy are also presented.
Lake and mire isolation data set for the estimation of post-glacial land uplift in Fennoscandia
Authors: Pohjola Jari , Turunen Jari , Lipping Tarmo 
Published: April 2020

Abstract. Postglacial land uplift is a complex process related to the continental ice retreat that took place about 10 000 years ago and thus started the viscoelastic response of the Earth's crust to rebound back to its equilibrium state. To empirically model the land uplift process based on past behaviour of shoreline displacement, data points of known spatial location, elevation and dating are needed. Such data can be obtained by studying the isolation of lakes and mires from the sea. Archaeological data on human settlements (i.e. human remains, fireplaces etc.) are also very useful as the settlements were indeed situated on dry land and were often located close to the coast. This information can be used to validate and update the postglacial land uplift model. In this paper, a collection of data underlying empirical land uplift modelling in Fennoscandia is presented. The data set is available at https://doi.org/10.1594/PANGAEA.905352 (Pohjola et al., 2019).

Parliamentary Scrutiny of Law Reform in Albania: Bodies, Procedures and Methods
This article throws light on the parliamentary scrutiny of law reform in Albania, which so far has not received sufficient attention in academic literature. The article provides a review of the bodies, procedures and mechanisms for the scrutiny of legal reform, as specified in the Constitution of Albania, Parliament’s Rules of Procedure and other specific statutes. Research on the activities of these bodies during the past three years, as reported by the official sources, throws light on the problematic aspects of their work and enables recommendations to be made which will lead to a more effective role of Parliament in legal reform. This is paramount considering the past few years of political instability in the country, at a time when Albanian’s European Integration is at stake
Characterizing Rapists and Their Victims in Select Nigeria Newspapers
Authors: Tade Oludayo , Udechukwu Collins 
Published: April 2020

While offender and victim characterization offers clues to devising preventive strategies and victim therapy, existing studies in Nigeria are yet to capture this empirically. Using two national dailies, about 331 rape cases have been analyzed. The rapists were found to be of the age group 18–55 years. The victims’ age has been reported to be between 1 and 20 years. Rape victims were mostly females (>90%) compared to males. Most of the rapists are labeled as familiar foes meaning, father, relatives, or neighbors. Third-party guardianship is mentioned as predatory.

Anthropogenic actions, including deforestation, disorganized urbanization, and globalization, contribute to emergence and reemergence of arboviruses worldwide, where Flavivirus is the most prevalent, and its continuous monitoring can help in preventive control strategies. Thus, the aim of this study was to detect flavivirus RNA in single hematophagous insects, which are used as sentinels. Total RNA was extracted from six Aedes aegypti stored since 2003 and from 100 Culicidae and collected through CDC trap in a public park of a Brazilian Northwest city of São Paulo State. Flavivirus was detected through RT/PCR targeting 230–250 bp of the RNA polymerase coding sequence (NS5). PCR amplicons were sequenced by Sanger method, used in comparative analysis over Basic Local Alignment Search Tool (BLAST) in GenBank, and subjected to Neighbor-Joining phylogenetic analyses. Efficiency of Flavivirus diagnosis was confirmed by detection of Dengue virus serotype 2 in Ae. aegypti. From the 100 collected insects, 19 were positive for Culex flavivirus (CxFV). NS5 partial sequence phylogenetic analysis clustered all CxFV in one branch separated from vertebrate flaviviruses, being applicable to the identification of Flavivirus species. The dipteran RNA extraction methodology described in this work supports detection of flaviviruses in single insects maintained in 80% ethanol, which can be used to constant arbovirus surveillance.
