    Sammanfattning : This work focuses on the design, synthesis, characterization, and application projections of low-coordinated heavy pnictogen-containing (described by the generic letter E, hence E=C) phosphaalkenes (P=C) and arsaalkenes (As=C), with emphasis on the E=C group motifs. The work aims to understand their functional and modular character, reactivity, and potential applications by stabilizing, isolating, and characterizing these species in low-coordination environments.

  2. 2. The Chicago Painter and the Villa Giulia Painter's group

    Författare :Siv Blomqvist-Linér; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Attic pottery; Classical art; Dionysos; iconography; maenads; mythological motifs; red-figure; satyrs; stamnoi; vase-painting;

    Sammanfattning : The Chicago Painter is a member of the Villa Giulia Painter's group during the decades around 450 B.C. in Athens. He is a red-figure vase painter who has been named by J. LÄS MER

  3. 3. Studies on the Polymorphism and Transcriptional Regulation of the ABO and P1PK Histo-blood Group Genes

    Författare :Britt Thuresson; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood group; ABO; A4GALT; P1PK; Gene regulation; Enhancer;

    Sammanfattning : Antigens of the clinically important ABO and P1PK blood group systems are carbohydrate structures. Thus the underlying genes do not encode antigens directly but glycosyltransferases that add specific sugar molecules to selected precursor chains. LÄS MER

  4. 4. Methyltransferase Ash1, histone methylation and their impact on Polycomb repression

    Författare :Eshagh Dorafshan Esfahani; Yuri B. Schwartz; Jan Larsson; Dale Dorsett; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Trithorax Group proteins; Polycomb Group proteins; PRC1; PRC2; PRE; histone methylation; histone ubiquitylation; Ash1; SET domain; H3K36; H3K27; Drosophila;

    Sammanfattning : Antagonistic interactions between Polycomb Group (PcG) and Trithorax Group (TrxG) proteins orchestrate the expression of key developmental genes. Distinct maternally loaded repressors establish the silenced state of these genes in cells where they should not be expressed and later PcG proteins sense whether a target gene is inactive and maintain the repression throughout multiple cell divisions.

  5. 5. Ya nos cayó el chahuistle: El cuento apocalíptico mexicano contemporáneo (1996-2016)

    Författare :Gabriela Mercado Narváez; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Mexican literature; short stories; End of the World; apocalyptic literature; apocalyptic motifs; quantitative analysis;

    Sammanfattning : The aim of this dissertation is to cover a gap left by literary criticism in the study of Mexican apocalyptic literature. Its main objective is to make a systematized and comprehensive characterization of contemporary apocalyptic short stories in Mexico, which have been overlooked in critical works due to their status as speculative fiction.
