Y-BLOKKA, 2019, sculpture, olive oil soap. The Y-Blokka sculpture was made of a solid bar of imported olive oil soap during the ongoing conflict surrounding the removal of the Y-Blokken at Akersgata 44, 0180 Oslo. The protest for the plan had great public momentum but no effect in saving the city planning changes to raze the building. The idea for the soap sculpture is the relationship to the Y form in the body and the impermanent qualities it has in both genetics and light. The bond between X and Y is dissolved in water, just as the soap will eventually become lesser and lesser when exposed to water. Yttrium and additional elemental qualities are connected to the Y-form. Visit this site for information on the architecture: Biological and medical reference follow the documentation photos. The artwork was exhibition in the Trøndelag Bildene Kunstneres summer exhibition 2021, prior to use. Fabrication of sculptures and inquiries:


“Structure, in the making and demolition of form, when brought into light with the human relationship with environment makes outcomes of social relationships evident to me. The description of toxic masculinity can be ascribed to the absence of masculinity. The exhausting petulance of progressive ideology has an emotional labor that seems to justify the self-proclaimed and righteous feminist. There are always costs and risks associated with any temporary benefit. The necessity for difference and discernment relative to constancy and healthy change has been fashioned into an ideological feedback loop with a populace unwilling to reconcile the consequences such ideologies have on life. In that I am interested in structures that endure, perhaps only in the intimate moments of grief, do humans reflect on the memory of what their actions cause.” -Mari Amman

Y Form, Biological Reference

Definition: noun, plural: immunoglobulins. (1) Any of several classes of structurally related glycoproteins in the blood serum, produced by plasma cells as an immune response against foreign agents (antigens); antibody. (2) The fraction of the blood serum containing antibodies.

Supplement: An immunoglobulin (Ig) is a glycoprotein; it is comprised of a glycan and a protein constituent. The basic functional unit of an immunoglobulin has a Y-shape. It consists of two identical heavy chains and two identical light chains. In each of these chains, there are variable and constant regions. The apical portion of the variable regions serves as antigen-binding site. The plasma cell produces immunoglobulins as a response to an antigen, i.e. non-self foreign agent. The immunoglobulin may also be described in this way: it is composed of two Fab (fragment, antigen-binding) regions and one fc (fragment, crystallizable) region. The Fabs include the antigen-combining sites whereas the fc region consists of the remaining constant sequence domains of the heavy chains, cell-binding site, and complement-binding sites. In placental mammals (including humans), there are five classes (or isotypes) of immunoglobulins based on structure and biological activity.

SS-B/La Antibodies, IgG, Serum Reporting Name: SS-B/La Ab, IgG, S, Useful for: evaluating patients with signs and symptoms of a connective tissue disease in whom the test for antinuclear antibodies is positive. Testing for SS-B/La antibodies is not useful in patients without demonstrable antinuclear antibodies.

Clinical Information: SS-B/La is an extractable nuclear antigen (ENA) composed of a 48-kD protein combined with RNA species. SS-B/La antibodies are found primarily in patients with Sjogren syndrome or lupus erythematosus (LE), where they occur with frequencies of approximately 60% and 15%, respectively.(1,2) SS-B/La antibodies occur only infrequently in the absence of SS-A/Ro antibodies. SS-B/La is 1 of 4 autoantigens commonly referred to as extractable nuclear antigens (ENA). The other ENA are SS-A/Ro, RNP, and Sm (Smith). Each ENA is composed of 1 or more proteins associated with cytoplasmic or small nuclear RNA species (snRNA) ranging in size from 80 to 350 nucleotides. Antibodies to ENA are common in patients with connective tissue diseases (systemic rheumatic diseases) including LE, mixed connective tissue disease, Sjogren syndrome, scleroderma (systemic sclerosis), and polymyositis/dermatomyositis. See Connective Tissue Disease Cascade (CTDC) in Special Instructions.

Interpretation: A positive result for SS-B/La antibodies is consistent with connective tissue disease, including Sjogren syndrome and lupus erythematosus.

Testing Algorithm: See Connective Tissue Disease Cascade (CTDC) in Special Instructions.
