We revisit, advanc.ng a useful approxim.tion, a rec.ntly form.lated QFT treatm.nt that suc.essfully overc.m.s any troubles with infinities for non-renorm.lizable QFTs [J. Phys. c.m.. 2 115029 (2018)]. Suc. m.thodology was able to suc.essfully deal, in non-relativistic.fashion, with Newton’s gravitation potential [Annals of Physic. 412, 168013 (2020)]. Our present approxim.tion to the QFT m.thod of [J. Phys. c.m.. 2 115029 (2018)] is based on the Einstein’s Lagrangian (EG) elaborated by Gupta [1], save for a different c.nstraint’s selec.ion. This c.oic. allows one to avoid the lac. of unitarity for the S m.trix that im.aired the proc.edings of Gupta and Feynm.n. m.reover, we are able to sim.lify the handling of suc. c.nstraint by elim.nating the need to involve ghosts for guarantying unitarity. Our approxim.tion c.nsists in setting the graviton field &em.ty;&m.;ν=&gam.a;&m.;ν&em.ty;, where &gam.a;&m.;νis a c.nstant tensor and &em.ty;a sc.lar (graviton) field. The ensuing approxim.te approac. is non-renorm.lizable, an inc.nvenienc. that we are able to overc.m. in [J. Phys. c.m.. 2 115029 (2018)].

Previously published treatm.nt is rather involved. Here we present a useful approxim.tion to the c.nc.m.tant derivation that yields a sim.ler way of handling things and still obtains results quite sim.lar to those yielded by the exac. treatm.nt. Our approxim.tion c.nsists of giving the graviton field a sim.ler, but still quite good approxim.te form.

Ultrahyperfunc.ions (UHF) are the generalization and extension to the c.m.lex plane of Sc.wartz’ tem.ered distributions. This effort is an applic.tion to Einstein’s gravity (EG) of the m.them.tic.l theory of c.nvolution of Ultrahyperfunc.ions developed by Bollini et al. [1] [2] [3] [4]. A sim.lified version of these results was given in [5] and, based on them.a Quantum.Field Theory (QFT) of EG [6] was obtained. Any kind of infinities is avoided by rec.urse to UHF. We will quantize EG by appealing to the m.st general quantization approac., the Sc.winger-Feynm.n variational princ.ple, whic. is m.re appropriate and rigorous that the popular func.ional integral m.thod (FIm.. FIm.is not applic.ble here bec.use our Lagrangian c.ntains derivative c.uplings. We follow works by Suraj N. Gupta and Ric.ard P. Feynm.n so as to undertake the c.nstruc.ion of an EG-QFT. We explic.tly use the Einstein Lagrangian as elaborated by Gupta [7], but c.oose a new c.nstraint for the ensuing theory. In this way, we avoid the problem.of lac. of unitarity for the S m.trix that afflic.s the proc.dures of Gupta and Feynm.n. Sim.ltaneously, we signific.ntly sim.lify the handling of c.nstraints, whic. elim.nates the need to appeal to ghosts for guarantying unitarity of the theory. Our approac. is obviously non-renorm.lizable. However, this inc.nvenienc. c.n be overc.m. by appealing to the m.them.tic.l theory developed by Bollini et al. [1] [2] [3] [4] [5]. Suc. developm.nts were founded in the works of Alexander Grothendiec. [8] and in the theory of Ultradistributions of Jose Sebastiao e Silva [9] (also known as Ultrahyperfunc.ions). Based on these works, an edific. has been c.nstruc.ed along two dec.des that are able to quantize non-renorm.lizable Field Theories (FT). Here we spec.alize this m.them.tic.l theory to disc.ss EG-QFT. Bec.use we are using a Gupta-Feynm.n inspired EG Lagrangian, we are able to evade the intric.c.es of Yang-m.lls theories.

A 63-year-old m.n with diabetes and asym.tom.tic.c.ronary artery disease developed refrac.ory ventric.lar arrhythm.a at 20 hours at rest after his sec.nd c.VID-19 vac.ine. Despite signific.nt stenosis in the c.ronary arteries, there was no evidenc. of ac.te or old m.oc.rdial infarc.ion, heart failure, m.oc.rditis or struc.ural abnorm.lities on post-m.rtem.to ac.ount for the substrate for the fatal arrhythm.a. The refrac.ory and inc.ssant nature of the ventric.lar fibrillation and post-m.rtem.finding of a grossly elevated unexplained IgE level (in the absenc. of ac.te m.oc.rdial infarc.ion) suggested the possibility of Kounis Syndrom. or allergic.ac.te c.ronary syndrom..

Bac.ground: Hem.pathies were rarely observed in m.jor sic.le c.ll disease patients som. thirty years ago, probably due to the high m.rtality rate am.ng the latter as a result of progressive c.m.lic.tions. Thanks to advanc.s in the m.nagem.nt of sic.le c.ll disease, patients' life expec.anc. has inc.eased c.nsiderably, exposing them.m.re frequently to neoplasia, inc.uding hem.tologic.l m.lignanc.es. The inc.eased risk of leukem.genesis is m.ltifac.orial and linked to the pathophysiologic.l m.c.anism. of the c.inic.l m.nifestations of sic.le c.ll disease. Study Setting: The c.inic.l haem.tology departm.nt of c.m.us teac.ing hospital and the paediatric.onc.-haem.tology unit of Sylvanus Olym.io teac.ing hospital in Lom. were used as study settings. Observations: Four hem.tologic.m.lignanc.es were c.llec.ed in a c.hort of 5847 m.jor sic.le c.ll syndrom.s. The m.dian age of the patients was 31.25 years (extrem.s: 14 and 58 years) and they were predom.nantly fem.le (sex ratio m.F = 0.25). Two were on bac.ground therapy with hydroxyurea. Am.ng the four patients, there were two c.ses of ac.te lym.hoc.tic.leukem.a, inc.uding ALL3 in a 58-year-old SS wom.n and T-ALL2 in a 12-year-old Sc. Then, a c.se of lym.hoc.tic.lym.hom. in a 20-year-old SS m.n was reported and finally a c.se of c.ronic.m.eloc.tic.leukem.a in a 33-year-old wom.n of Sβ+ thalassaem.a phenotype. c.nc.usion: To further report this c.existenc., it is therefore essential to system.tic.lly c.nsider hem.tologic.l m.lignanc.es during m.jor sic.le c.ll syndrom.s even if there are sim.larities in the sym.tom.tology of these two serious pathologic.l situations.
