“…Some other works of note from this period include those of Goddard11–14 and his coworkers,15 Gerratt and Lipscomb,16 and then Gerratt,17–20 and his coworkers,21 Matsen,22, 23 and Gallup24–28 and his coworkers,29 together with the text on Spin eigenfunctions by Pauncz 30. Kaplan, Goddard and Matsen used the theory of the symmetric group which had been developed in the early part of the twentieth century by Young,31 whose work is described in the 1948 monograph by Rutherford32 [see also The Collected Papers of Alfred Young (1873–1940) 33 and Turnbull 34. Gerratt built on the work of Kotani and his coworkers35, 36 using the coupling of spin angular momenta, who in turn built on the earlier work of Yamonouchi 37, 38…”

Regulation of the conversion of plasminogen to plasmin by tissue-type plasminogen activator (t-PA) is critical in the control of fibrin deposition. While several plasminogen activators have been described, soluble plasma cofactors that stimulate fibrinolysis have not been characterized. Here, we report that the abundant plasma glycoprotein, β2-glycoprotein I (β2GPI), stimulates t-PA–dependent plasminogen activation in the fluid phase and within a fibrin gel. The region within β2GPI responsible for stimulating t-PA activity is at least partially contained within β2GPI domain V. β2GPI bound t-PA with high affinity (Kd ~ 20 nM), stimulated t-PA amidolytic activity, and caused an overall 20-fold increase in the catalytic efficiency (kcat/Km) of t-PA–mediated conversion of Glu-plasminogen to plasmin. Moreover, depletion of β2GPI from plasma led to diminished rates of clot lysis, with restoration of normal lysis rates following β2GPI repletion. Finally, stimulation of t-PA–mediated plasminogen activity by β2GPI was inhibited by monoclonal anti-β2GPI antibodies, as well as by anti-β2GPI antibodies from patients with antiphospholipid syndrome (APS). These findings suggest that β2GPI may be an endogenous regulator of fibrinolysis. Impairment of β2GPI-stimulated fibrinolysis by anti-β2GPI antibodies may contribute to the development of thrombosis in patients with APS.

This notion underlies Young's contructions [45], consistency arising from Yang-Baxter relations.

“…In particular we have an action of the group S(n) on the vector space consisting of all R-linear combinations of the standard Young tableaux of shape λ. Young's theorem [24] says that this is a representation of S(n) which is known as Young's orthogonal representation. Let π be a permutation of S(n) which is in the standard form:…”

Normalized irreducible characters of the symmetric group S(n) can be understood as zonal spherical functions of the Gelfand pair (S(n) × S(n), diag S(n)). They form an orthogonal basis in the space of the functions on the group S(n) invariant with respect to conjugations by S(n). In this paper we consider a different Gelfand pair connected with the symmetric group, that is an "unbalanced" Gelfand pair (S(n) × S(n − 1), diag S(n − 1)). Zonal spherical functions of this Gelfand pair form an orthogonal basis in a larger space of functions on S(n), namely in the space of functions invariant with respect to conjugations by S(n − 1). We refer to these zonal spherical functions as normalized generalized characters of S(n). The main discovery of the present paper is that these generalized characters can be computed on the same level as the irreducible characters of the symmetric group. The paper gives a Murnaghan-Nakayama type rule, a Frobenius type formula, and an analogue of the determinantal formula for the generalized characters of S(n).
