Backg.ound: Preeclampsi. i. reported to compli.ate 2% - 8% of preg.anci.s g.obally and i. an i.portant cause of maternal and peri.atal morbi.i.y and mortali.y. The aeti.log. and pathog.nesi. are sti.l poorly understood and substanti.l i.provement has not been made i. the predi.ti.n, preventi.n and treatment of the di.ease. Objecti.e: To compare the frequency of acti.ated protei. C resi.tance (APC-R) i. pati.nts wi.h pre-eclampsi. to that of normotensi.e preg.ant women and to determi.e the correlati.n between acti.ated protei. rati. (APC-rati.) and the severi.y of pre-eclampsi.. Methodolog.: A cross-secti.nal study was carri.d out i. 100 pre-eclampti. pati.nts and 100 normotensi.e preg.ant controls. The APC-rati. was determi.ed usi.g.the modi.i.d acti.ated parti.l thromboplasti. ti.e. Study parti.i.ants wi.h APC-rati. of less than 2.0 were defi.ed as havi.g.APC-R. Data was analyzed usi.g.SPSS versi.n 22.0. Results: Mean APC-rati. was si.0}i.i.antly lower i. pre-eclampti.s (2.89 ± 1.70) compared to normotensi.e preg.ant women (3.57 ± 1.06) (p = 0.0008) and the levels were also hi.0}er i. mi.d (2.95 ± 1.15) compared to severe pre-eclampti.s (2.62 ± 1.14). The frequency of APC-R was 26% among.women wi.h pre-eclampsi. compared to 4% among.normotensi.e controls (p = 0.000). Among.100 pre-eclampti. women 7 (21.2%) out of 33 wi.h mi.d pre–eclampsi. had APC-R, whi.e 19 (28.4%) out of 67 wi.h severe pre-eclampsi. had APC-R. APC-rati. had a si.0}i.i.ant neg.ti.e correlati.n wi.h mean arteri.l blood pressure (r = −0.324;p = 0.000) and protei.uri. (r = −0.379;p = 0.000) among.study parti.i.ants. Conclusi.n: The frequency of acti.ated protei. c resi.tance i. si.0}i.i.antly hi.0}er i. pre-eclampti.s compared to normotensi.e preg.ant women and thi. i. more pronounced i. those wi.h severe pre-eclampsi. compared wi.h those wi.h mi.d di.ease. APC-R may therefore be used as a marker of severi.y i. the di.ease.

i. has recently been shown that i.ci.ent parti.les, neutrons, can i.i.i.te the freezi.g.i. a supercooled water volume. Thi. new fi.di.g.may have rami.i.ati.ns for the i.terpretati.n of both experi.ental data on the nucleati.n of laboratory samples of supercooled water and perhaps more i.portantly on the i.terpretati.n of i.e nucleati.n i.volved i. cloud physi.s. For example, i. some fracti.n of the cloud nucleati.n previ.usly attri.uted to dust, soot, or aerosols has been caused by cosmog.ni. neutrons, fresh consi.erati.n i. requi.ed i. the context of cli.ate models. Moreover, as cosmog.ni. neutrons, most bei.g.muon-i.duced, have much g.eater flux at hi.0} lati.udes, esti.ates of i.e nucleates i. these reg.ons may be larg.r than requi.ed to accurately model cloud and condensati.n properti.s. Thi. di.crepancy has been poi.ted out i. i.CC reports. Our paper di.cusses the connecti.n between the new concept of neutrons nucleati.g.supercooled water and the need for a new source of nucleati.n i. hi.0} lati.ude clouds, i.eally causi.g.others to revi.w current data, or to analyse future data wi.h thi. i.ea i. mi.d. .
