Important Diagnostic Feature

Cabassous comprises armadillos lacking a full osteoderm cover in the tail, justifying its common name naked-tailed armadillos. In the only taxonomic revision of the genus, in 1980, four living species were recognized, including a polytypic taxon with two subspecies. Recent studies have questioned this classification, but a comprehensive taxonomic review is lacking. Here, we revise the taxonomy of the genus Cabassous using complementary morphological approaches and clarify the geographical limits of naked-tailed armadillo species. Based on qualitative and quantitative analyses, we recognize five living species: C. centralis, C. chacoensis, C. squamicaudis, C. unicinctus, and C. tatouay. Most of the species can be easily differentiated using external or cranial traits, except C. centralis and C. unicinctus, which share several morphological features. The scutes pattern on the cephalic shield is an important diagnostic feature in naked-tailed armadillos and can be easily applied in field studies. Cabassous squamicaudis and C. unicinctus were previously treated as subspecies but we show they have conspicuous diagnostic traits, without mixture of characters even in closer contact. Cabassous species can be classified as open-dwellers (C. chacoensis and C. squamicaudis), forest-dwellers (C. centralis and C. unicinctus), or of more generalist habits (C. tatouay). We designate a lectotype for C. unicinctus to preserve its long-term nomenclature use.

Prosocial Behaviours

This article documents the long-term impacts of international development volunteering (IDV) on the prosocial behaviours, educational or career choices, and global citizenship activities of returned international volunteers (RVs). Findings from a 2018 survey completed by 450 Canadian RVs show how IDV can contribute to global citizenship and civic engagement. Qualitative and quantitative analyses demonstrate how IDV can help to build a more empathetic and justice-oriented society dedicated to addressing the causes and consequences of global poverty and inequality. As a distinctive model for transformational learning, this study illustrates the value of IDV as a model for cross-cultural education shaping values of global civic responsibility.

Important Diagnostic Feature

Context.— Presence of antibodies to nuclear antigens (ANAs) above a threshold titer is an important diagnostic feature of several autoimmune diseases, yet titers reported vary between laboratories. Proficiency survey results can help clarify factors contributing to the variability. Objective.— To determine the contribution of HEp-2 ANA kits from different manufacturers to the variation in titers, and assess whether the differences between kits are consistent over the long term. Design.— HEp-2 ANA titers reported by laboratories participating in the external quality assessment proficiency testing surveys conducted by the College of American Pathologists between 2008 and 2018 were analyzed. The ANA titers reported for each specimen were ranked according to the kits being used by testing laboratories, and the statistical significance of the differences was determined. Results.— The ANA titer results were strongly influenced by the HEp-2 ANA kit used (P < .001). During the 11 years studied, the rank order of the ANA titer for each kit relative to the other kits was remarkably consistent. The rank of ANA titer for individual ANA patterns observed for each kit was similar to the overall rank of that kit. Conclusions.— Variability in ANA titers was strongly associated with the kits used, and the differences between kits were quite consistent during the 11 years studied. Because the variability is not random, it has the potential to be managed by harmonizing kits, which could lead to improved consistency in reporting ANA titers.

BackgroundThe aims were to investigate cross-culturally the subjective experience of long-term psychiatric patients to determine whether or not they would define their current life situation predominantly in terms of illness.MethodThe design is a two-by-two comparison by ethnicity (Latino and Euro-American) and diagnosis (schizophrenia and unipolar depression) of 80 subjects for DSM–III–R criteria according to the SADS. Patients were interviewed using a semi-structured interview (Context of Illness Experience) yielding data coded for qualitative and quantitative analyses.ResultsWhile significant ethnic differences were observed, nearly half the sample did not include illness in their description of their life situation. Other domains (e. g. activities, events) and the extent to which patients perceived themselves as in- or out-of-step with the “rhythm of life” were identified as central patient concerns.ConclusionsEmpirical research on the subjective experiences and representations of the life situation of patients offers clues to the course and treatment of persistent psychiatric disorder.

Data Result

Inorganic particulate material of diverse types is present in the ambient and occupational environment, and exposure to such materials is a well recognized cause of some lung disease. To investigate the interaction of inhaled inorganic particulates with the lung it is necessary to obtain quantitative information on the particulate burden of lung tissue in a wide variety of situations. The vast majority of diagnostic and experimental tissue samples (biopsies and autopsies) are fixed with formaldehyde solutions, dehydrated with organic solvents and embedded in paraffin wax. Over the past 16 years, I have attempted to obtain maximal analytical use of such tissue with minimal preparative steps. Unique diagnostic and research data result from both qualitative and quantitative analyses of sections. Most of the data has been related to inhaled inorganic particulates in lungs, but the basic methods are applicable to any tissues. The preparations are primarily designed for SEM use, but they are stable for storage and transport to other laboratories and several other instruments (e.g., for SIMS techniques).

By obtaining changes on gene sequences of living things with the applied biotechnological methods; The idea of "Genetically Modified Organisms (GMO)", which aims to bring the living creature in question the original gene combinations with the desired characteristics, came to life in the late twentieth century. Despite the high probability that hunger problems may increase with the increasing world population; It is thought that plant breeding with classical farming methods will be insufficient in solving these problems. With various GMO applications developed all over the world, it aims to produce solutions to these problems. With the presence of GMO, it was possible to increase the shelf life of qualitative and quantitative values of the existing foods. In addition, decreases in agricultural use of pesticides used in agricultural struggle and threatening human health with GMO production are noteworthy. However, some concerns about anomalies that may occur in living things fed GMO products remain on the agenda. Because, in the long term, there is no clear and precise information that GMO will not have negative effects on living things; There are many recorded incidents showing their negative effects.

The article presents and analyzes data of competitive varietal testing of promising varieties and lines of spring barley for yield and brewing qualities. Field studies were conducted in 2014–2017 on dark gray forest heavy loam soil. Agrochemical parameters are total nitrogen – 0.24%, humus content in a layer of 0-40 cm (according to Tyurin) – 5.19%, hydrolysis nitrogen – 123.5 mg / kg, salt extract pH – 4.92 mg-eq / 100g; labile phosphorus - 34.6 mg / 100g, labile potassium – 20.0 mg / 100g. The forerunner is winter wheat. Meteorological conditions in the years of research differed from each other and from the average long-term value. Barley samples were assessed by the protein content in the grain (GOST 10846-91), extract content (GOST 12130-77), weight 1000 grains (GOST 10842-89). Ecological plasticity was determined by the method proposed by E.D. Nettevich, A.I. Morgunov and M.I. Maksimenko, stability index (Ľ) by A. A. Gryaznov, indicator of stability level (Puss) by E. D. Nettevich and A. I. Morgunov. The main measure for assessing quality indicators is protein content. Many other biochemical and technological features of grain depend on its level. The experimental data convincingly testify to the significant influence of the soil and climatic conditions on the yield and, especially, on the brewing qualities of barley in the conditions of the Central Region of the Nonchernozem Zone. According to the studied traits, new valuable varieties Nadezhny, Sir, Noble and selection lines 141 / 1-09 h 746, 23 / 1-10 h 784, distinguished by high adaptability and resistance to adverse environmental factors, have been identified.

Social behaviour in solitary carnivores has long been an active area of investigation but for many species remains largely founded in conjecture compared to our understanding of sociality in group-living species. The social organization of the wolverine has, until now, received little attention beyond its portrayal as a typical mustelid social system. In this chapter the authors compile observations of social interactions from multiple wolverine field studies, which are integrated into an ecological framework. An ethological model for the wolverine is proposed that reveals an intricate social organization, which is driven by variable resource availability within extremely large territories and supports social behaviour that underpins offspring development.
