ABSTRACT Various genotypes of norovirus (NoV) (genogroup I genotype 1 [GI.1], -2, -4, -5, -8, -11, -12, and -14; GII.3, -4, -6, -7, -10, -13, -14, and -15), and sapovirus (SaV) (GI.1 and GI.2, GII.1, and GIV.1) were detected from raw sewage from April 2006 to March 2008, while limited numbers of genotypes of NoV (GI.8, GII.4, GII.6, and GII.13) and SaV (GII.3 and GIV.1) and of NoV (GII.4, GII.7, and GII.13) were detected from clinical cases and healthy children, respectively. During the winter 2006 to 2008, a large number of sporadic gastroenteritis outbreaks and many outbreaks caused by NoV GII.4 occurred among inhabitants in Toyama, Japan. The copy number of genomes of NoV GII detected from raw sewage changed in relation to the number of outbreaks. NoV strains of the same genotypes observed in both raw sewage and human specimens belonged to the same cluster by phylogenetic analysis and had almost identical nucleotide sequences among each genotype. These data suggest that NoVs and SaVs detected from raw sewage reflect the viruses circulating in the community, irrespective of symptoms, and that subclinical infections of NoV are common in Japan. Combined surveys of raw sewage with those of clinical cases help us to understand the relationship between infection of these viruses and gastroenteritis.

In Uruguay, Lacanian ideas arrived in the 1960s, into a context of Kleinian hegemony. Adopting a discursive approach, this study researched the initial reception of these ideas and its effects on clinical practices. We gathered a corpus of discursive data from clinical cases and theoretical-doctrinal articles (from the 1960s, 1970s and 1980s). In order to examine the effects of Lacanian ideas, we analysed the difference in the way of interpreting the clinical material before and after Lacan's reception. The results of this research illuminate some epistemological problems of psychoanalysis, especially the relationship between theory and clinical practice.

A number of clinical studies have revealed that there is an association between major depression (MD) and gastroesophageal reflux disease (GERD). Both the diseases are shown to affect a large proportion of the global population. More advanced studies for understanding the comorbidity mechanism of these two diseases can shed light on developing new therapies of both diseases. To the best of our knowledge, there has not been any research work in the literature investigating the relationship between MD and GERD using their miRNA biomarkers. We adopt a phylogenetic analysis to analyze their miRNA biomarkers. From our analyzed results, the association between these two diseases can be explored through miRNA phylogeny. In addition to evidence from the phylogenetic analysis, we also demonstrate epidemiological evidence for the relationship between MD and GERD based on Taiwan biobank data.

AbstractChromothripsis is detectable in 20–30% of newly diagnosed multiple myeloma (NDMM) patients and is emerging as a new independent adverse prognostic factor. In this study we interrogate 752 NDMM patients using whole genome sequencing (WGS) to investigate the relationship of copy number (CN) signatures to chromothripsis and show they are highly associated. CN signatures are highly predictive of the presence of chromothripsis (AUC = 0.90) and can be used identify its adverse prognostic impact. The ability of CN signatures to predict the presence of chromothripsis is confirmed in a validation series of WGS comprised of 235 hematological cancers (AUC = 0.97) and an independent series of 34 NDMM (AUC = 0.87). We show that CN signatures can also be derived from whole exome data (WES) and using 677 cases from the same series of NDMM, we are able to predict both the presence of chromothripsis (AUC = 0.82) and its adverse prognostic impact. CN signatures constitute a flexible tool to identify the presence of chromothripsis and is applicable to WES and WGS data.

The Relationship

MicroRNA (miRNA) is a small non-coding RNA that functions in the epigenetics control of gene expression, which can be used as a useful biomarker for diseases. Anti-NMDA receptor (anti-NMDAR) encephalitis is an acute autoimmune disorder. Some patients have been found to have tumors, specifically teratomas. This disease occurs more often in females than in males. Most of them have a significant recovery after tumor resection, which shows that the tumor may induce anti-NMDAR encephalitis. In this study, I review microRNA (miRNA) biomarkers that are associated with anti-NMDAR encephalitis and related tumors, respectively. To the best of my knowledge, there has not been any research in the literature investigating the relationship between anti-NMDAR encephalitis and tumors through their miRNA biomarkers. I adopt a phylogenetic analysis to plot the phylogenetic trees of their miRNA biomarkers. From the analyzed results, it may be concluded that (i) there is a relationship between these tumors and anti-NMDAR encephalitis, and (ii) this disease occurs more often in females than in males. This sheds light on this issue through miRNA intervention.

The research of the microbiome concerning various diseases has grown in the last ten years due to the advances in molecular biology and next-generation sequencing, finding interactions with various pathologies. The new coronavirus 19 (SARS-COV 2) pandemic has aroused interest in the study of multiple factors that could influence in the development of symptoms mainly due to the interaction of the microbiome whether of the respiratory or gastrointestinal tract finally in the prognosis. Therefore, in this study, we focus on reviewing and analyzing the current bibliography of research and clinical cases about the relationship between the lung and gut microbiome and COVID-19, highlighting its effect on infected patients, aiming to contribute to this new line of research. Keywords: Microbiome, COVID-19, SARS-COV 2, gut microbiome, lung microbiome.

Several soil samples from different habitats in Badakhshan province of Afghanistan were collected to isolate and characterize bacteria feeding nematodes. The Galleria mellonella-baiting method was used for the isolation of the Afghan insect-associated nematodes. The nematodes were studied using morphological and morphometric data. The Oscheius specimen was characterized by a longer body (630–820 µm) and shorter pharynx (125–145 µm), whereas other morphological characters were not unusual. The Diploscapter specimen had an annulated cuticle, with lip region width 1.5 times shorter than the stoma, and had separated pharyngeal corpus from the isthmus and vulva located in the middle of the body. The molecular data were derived using three loci; 18S, 28S (D2/D3 segment), and ITS rRNA region, which were utilized to measure the genetic distance. The phylogenetic analysis was conducted to reconstruct the relationship tree. Both morphological and molecular approaches confirmed the identity of nematode isolates as Oscheius tipulae and Diploscapter coronatus. This is the first report of insect-associated nematodes from the soil of Afghanistan. Both species were capable of infecting and killing G. mellonella larvae in less than 96 h.

Introduction Ventricular septal defect (VSD) is an opening in the interventricular septum. 30-50% of patients with congenital heart disease have VSD. Objective The aim of the study was to determine the dependence of the left ventricular diastolic dimension (LVD), left ventricular systolic dimension (LVS), shortening fraction (SF), left atrium (LA), pulmonary artery truncus (TPA) on the body surface and compare their values among experimental, control and a group of healthy children. Values of maximal systolic gradient pressure (Pvsd) of VSD were compared with children from one experimental and control group. Method Children were divided into three groups: experimental (32 children with VSD that were to go to surgery), control (20 children with VSD who did not require surgery) and 40 healthy children. Measurements of LVD, LVS, SF, LA, TPA were performed in accordance to recommendations of the American Echocardiographic Association. The value of Pvsd was calculated from the maximal flow velocity (V) in VSD using the following formula: Pvsd=4xV? (mm Hg). Results For children from the experimental group, the relationship between the body surface and the variability of the LVD was explained with 56.85%, LVS with 66.15%, SF with 4.9%, TPA with 58.92%. For children from the control group, the relationship between the body surface and the variability of LVD was explained with 88.8%, LVS with 72.5%, SF with 0.42%, PA with 58.92%. For healthy children, the relationship between the body surface and the variabilitiy of the LVD was explained with 88.8%, LVS with 88.78%, SF with 5.25% and PA with 84.75%. There was a significant statistical difference between average values of Pvsd in the experimental and control group (p<0.02). Conclusion The presence of the large VSD has an influence on the enlargement of LVD, LVS, SF, TPA. The enlargement of the size of the pulmonary artery depends on the presence of VSD and there is a direct variation in the magnitude of the shunt. There is a relationship and significant dependence of the LVS and LVD on the body surface. There is no statistically significant dependence between SF and body surface.

Introduction: The relationships within the Pyrrhura species complex are partly unresolved. In this study, a comprehensive phylogenetic analysis of the Pyrrhura picta-leucotis complex was carried out, covering all species except P. subandina. Material and Methods: We made a morphological analysis of 745 preserved specimens of all the taxa in different museums. Nucleotide sequences of the mitochondrial cytochrome gene were generated and used to reconstruct a molecular phylogeny of Pyrrhura. Results and Discussion: Our results show that the complex is divided into 6 main groups comprising 15 species. P. dilutissima, regarded up to now as a subspecies of P. peruviana, acquires species status and three new subspecies are described. We also provide evidence that P. roseifrons is a paraphyletic group, indicating the existence of probably 3 lineages of which 2 deserve species status.

AbstractMariner-like element sequences were recovered from the genome of the orange wheat midge, Sitodiplosis mosellana (Géhin), with degenerate PCR primers designed to conserved regions of mariner transposases. The deduced amino acid sequences of the mariner-like transposases from S. mosellana showed 67% to 78% identity with the peptide sequences of other mariner transposases. A phylogenetic analysis revealed that the mariner-like elements from S. mosellana grouped in the mauritiana subfamily of mariner transposons. Results from Southern blot analysis suggest mariner-like elements are at a moderate copy number in the genome of S. mosellana.

Phylogenetic Revision

AbstractA phylogenetic revision of the Neotropical riodinid genus Calydna Doubleday and relatives is presented. A phylogenetic analysis for all twenty species of Calydna using thirty-eight characters of adult morphology generated four most parsimonious cladograms. Calydna is characterised to contain eighteen species, divided here into three monophyletic species groups with the relationship caieta group + (thersander group + hiria group). A new genus Echydna Hall gen. n. is described for the most basal clade, containing chaseba Hewitson and punctata C. & R. Felder, which are transferred from Calydna (combs. n.). The taxonomy, morphology, biogeography and biology of both genera are discussed, locality data is listed and mapped, and the adults and male and female genitalia are illustrated for all species. Concealed male abdominal androconial scales, which phylogenetically unite the thersander and hiria groups, are reported for the first time outside of the tribes Symmachiini and Nymphidiini. Two new species are described, Calydna jeannea sp. n. and Calydna nicolayi sp. n., and the replacement name fissilisima is provided for the unavailable name fissilis Stichel; maculosa Bates is transferred from Calydna to Callistium Stichel (comb. n.).
