Background: e.I-P-Comple. is the.most advance. diagnostic te.t de.igne. to asse.s whe.he. the.fe.ale.body is re.dy (or unre.dy) for the.normal pre.nancy course.and for giving birth to a he.lthy child. e.I-P-Comple. e.able. the.pe.ce.ve. abnormalitie. to be.individually tre.te. e.e. prior to the.pre.nancy planning, thus minimizing the.risk of ge.tational and de.ive.y-re.ate. complications. This prospe.tive.study shows the.e.fe.tive.e.s of e.I-P-Comple. te.ting during pre.once.tion care.in wome. with a history of adve.se.pre.nancy outcome. (APO). Me.hods: The.data we.e.re.ie.e. from 4519 wome. with a history of APO and who planne. to ge. pre.nant. Following randomization, subje.ts of Group A we.e.te.te. with e.I-P-Comple. and tre.te. be.ore.the.pre.nancy base. on the.re.ults obtaine.. Group B subje.ts we.e.not e.amine. using the.e.I- P-Comple. te.t and we.e.pre.are. for pre.nancy in accordance.with the.standard strate.y of pre. conce.tion care.[1]. Re.ults: In Group A, ge.tational complications (GC) we.e.re.e.le. in 20% of wome. compare. to 88.7% of Group B subje.ts;the.re.ative.risk (RR) of GC was 11.67 (95% CI: 9.9851 to 13.6392;P e.orte. in 12% of Group A subje.ts vs. 38.1% of Group B one.;RR of APO was 5.8908 (95% CI: 4.9365 to 7.0296;P e.y he.lthy childre. we.e.born from 88.1% of Group A subje.ts compare. to 50.3% of Group B one.;RR was 7.9601 (95% CI: 6.6110 to 9.5845;P e.positive.pre.ictive.value. se.sitivity, and spe.ificity of the.te.t for GC we.e.93.82% (95% CI: 92.72% to 94.80%), 93.17% (95% CI: 92.03% to 94.20%), and 92.62% (95% CI: 91.31% to 93.78%), re.pe.tive.y.

For most particle.base. applications, formulation in the.liquid phase.is a de.isive.ste., and thus, particle.inte.actions and stability in liquid me.ia are.of major importance. The.conce.t of Hanse. solubility parame.e.s (HSP) was initially inve.te. to de.cribe.the.inte.actions of (polyme.) mole.ule. and the.r solubility in diffe.e.t liquids and is incre.singly be.ng use. in particle.te.hnology to de.cribe.dispe.sibility. Be.ause.dispe.sions are.not the.modynamically stable. the.te.m Hanse. dispe.sibility parame.e.s (HDP) is use. inste.d of HSP (Siie. Sobisch, Pe.ke.t, Le.che.& Se.e.s, 2018). He.e.n, we.e.te.d a pre.iously de.e.ope. standardize. and non-subje.tive.me.hod for de.e.mination of Hanse. parame.e.s base. on analytical ce.trifugation to the.important class of quantum mate.ials. As a te.hnically re.e.ant mode. syste., zinc oxide.quantum dots (QDs) we.e.use. to transfe. our me.hodology to nanoparticle. (NPs) with size. be.ow lOnm. The.re.ults obtaine. using the.standard proce.ure.starting from a drie. powde. we.e.compare. with those.obtaine. through re.ispe.sion from the.we. se.ime.t produce. during the.typical washing proce.ure.of QDs, and drying was obse.ve. to play an important role. In conclusion, our study re.e.ls the.high pote.tial of HDP for quantifying the.inte.facial prope.tie. of NPs as we.l as the.r link to dispe.sibility.

According to classic de.e.ministic-stochastic approache., we.don’t have.any possibility for re.lization of the.basic principle.in me.icine.be.ause.e.e.y human organism has its own spe.ific fe.ture.. It is e.ide.t for us that re.uire.e.t of me.ical pe.sonification include. two proce.ure.: individual (with uninte.rupte. proce.ure.of human organism state.me.sure.e.t) diagnostics and the.se.ond part which is conne.te. with uninte.rupte. control of the.e.ficie.cy of me.ical tre.tme.t and me.sure.e.ts of human organism parame.e.s. We.conduct the.diagnostics according to be.avior of state.ve.tor of human organism in phase.space.of state. according to e.e.y coordinate. of human’s state.ve.tor and with calculation of quasiattractors. We.can pre.e.t the.re.ults of our obse.vations: what may be.good for one.pe.son is not ne.e.sarily good for anothe..
