AbstractWe derive a necessary and sufficient condition for HNN-extensions of cyclic subgroup separable groups with cyclic associated subgroups to be cyclic subgroup separable. Applying this, we explicitly characterize the residual finiteness and the cyclic subgroup separability of HNN-extensions of abelian groups with cyclic associated subgroups. We also consider these residual properties ofHNN-extensions of nilpotent groups with cyclic associated subgroups.

The work examines the connection between the size of informal subgroups that arise in production groups and some relationship phenomena (interpersonal and subgroup trust, interpersonal and subgroup identity, interpersonal and subgroup conflict) within these subgroups. It also compares the convexity of the corresponding relationship phenomena in informal dyads and larger subgroups. The data from two empirical studies on different samples of work groups (N=37 and N=42) were used. In these groups, 65 and 71 informal subgroups, respectively, were found.

Furthermore, we present the associated examples and theorems, and prove these associated theorems. After that, we interpret the image and pre-image of BCF subgroups under homomorphism and prove the related theorems.

Its planarity is discussed whenever $G$ is an abelian group, $p$-group, nilpotent, supersoluble or soluble group. Finally, the induced subgraph of stable subgroup graph with vertex set whole non-normal subgroups is considered and its planarity is verified for some certain groups.

AbstractA subgroup H of an abelian p–group G is pure in G if the inclusion map of H into G is an isometry with respect to the (pseudo-) metrics on H and G associated with their p–adic topologies. In this paper, those subgroups (called here imbedded subgroups) of abelian groups for which the inclusion is a homeomorphism with respect to the p–adic topologies are studied, the aim being to compare the concepts of imbeddedness and purity. Perhaps the main results indicate that imbedded subgroups are considerably more abundant than pure subgroups. Groups for which this is not the case are characteri

4519 Background: Metastatic RCC (mRCC) is a molecularly heterogeneous disease. Transcriptomic analysis in the Phase 3 IMmotion 151 (Im151) trial identified 7 molecular subtypes that showed differential outcomes to Atezolizumab+Bevacizumab (A+B) vs Sunitinib (S) treatment (Motzer, Cancer Cell 2020). Here, we present histological correlates of these subtypes as identified in whole slide images (WSI) of hematoxylin and eosin (H&E) stained tumors. Methods: ML models identified 922 H&E derived, human interpretable histological features (ML HIFs) in RCC associated with tumor and stromal (inc

Let G be a nondiscrete locally compact Hausdorff abelian group. It is shown that if G contains an open torsion subgroup, then every proper dense subgroup of G is contained in a maximal subgroup; while if G has no open torsion subgroup, then it has a dense subgroup D such that G/D is algebraically isomorphic to R, the additive group of reals. With each G, containing an open torsion subgroup, we associate the least positive integer n such that the nth multiple of every discontinuous character of G is continuous. The following are proved equivalent for a nondiscrete locally compact abelian group

Calcium carbide (CaC2) is a commonly used ripening agent, although its primary use is in welding. Use of CaC2 in ripening fruits is considered harmful because it contains traces of phosphorous and arsenic. Aim of this study was to investigate associated risks and pathogenic (biochemical and histological) effects of consuming CaC2-ripened banana as a meal, before and/or during pregnancy on maternal and neonatal livers of adult female wistar rats. 36 healthy-looking, nulliparous, adult female wistar rats weighing between 150-200g were utilized.

Abstract Background Atypical teratoid/rhabdoid tumors (ATRTs) are known to exhibit molecular and clinical heterogeneity even though SMARCB1 inactivation is the sole recurrent genetic event present in nearly all cases. Indeed, recent studies demonstrated 3 molecular subgroups of ATRTs that are genetically, epigenetically, and clinically distinct. As these studies included different numbers of tumors, various subgrouping techniques, and naming, an international working group sought to align previous findings and to reach a consensus on nomenclature and clinicopathological significance of ATRT su

Endocrine therapy (ET) is typically the first-line treatment in hormone receptor-positive, human epidermal growth receptor 2-negative (HR+/HER2) breast cancer (BC) patients; however, almost half of the patients exhibit ET resistance after initial response. Mechanisms of ET resistance are not fully understood, and require an integrated epigenetic, transcriptomic and genetic approach. We conducted ATAC, RNA, and whole-exome sequencing on primary and metastatic BC (pBC and mBC) from 459 HR+/HER2- patients. pBC samples were derived from tumor resections of patients, which were then treated with ad

A multidimensional model of intragroup conflict was used, which includes two dimensions: five levels of conflict (i.e., interpersonal (individual–individual), micro-group (individual–subgroup), group (individual–group), subgroup–subgroup, and subgroup–group) and two types of conflict (activity-oriented and subject-oriented).

Abstract Recognition of specific T-ALL subgroups based upon cytogenetic aberrations may have prognostic relevance. The prognostic relevance of recurrent molecular-cytogenetic abnormalities using RQ-PCR and FISH was established for T-ALL patients enrolled on the DCOG protocols, and assigned to SIL-TAL, HOX11, HOX11L2, or CALM-AF10 subgroups or a rest group lacking any of these abnormalities. RQ-PCR data almost completely matched with FISH data. CALM-AF10 was associated with a poor outcome (p=0.005), whereas HOX11L2 and TAL1 subgroups demonstrated a strong trend towards poor and good outcome, re

It turned out that apart from, perhaps, the type 2Dl, such intermediate subgroups are standard, that is, they are exhausted by the groups G(P)H for some intermediate subfield P, K ⊆ P ⊆ F, and of the diagonal subgroup H

Medulloblastoma (MB) is the most common type of malignant pediatric brain tumor. Neuropilin-1 (NRP1), encoded by the NRP1 gene, is a transmembrane glycoprotein overexpressed in several types of cancer. Previous studies indicate that NRP1 inhibition displays antitumor effects in MB models and higher NRP1 levels are associated with poorer prognosis in MB patients. Here, we used a large MB tumor dataset to examine NRP1 gene expression in different molecular subgroups and subtypes of MB. We found overall widespread NRP1 expression across MB samples. Tumors in the sonic hedgehog (SHH) subgroup show

Bacterial vaginosis (BV) is the most common infection of the lower reproductive tract among women of reproductive age. Recurrent infections and antibiotic resistance associated with biofilms remain significant challenges for BV treatment. Gardnerella species are commonly found in women with and without BV, indicating that genetic differences among Gardnerella isolates may distinguish pathogenic from commensal subgroups. This study isolated 11 Gardnerella strains from vaginal samples obtained from women with BV before or after treatment. The biofilm formation ability of each strain was examined
