We determine new linea. ephemerides of tra.siting exopla.ets using long-ca.ence de-trended da.a.from qua.ters Q1 to Q17 of the Kepler mission. We a.a.ysed tra.sit-timing va.ia.ion(TTV) dia.ra.s of 2098 extra.ola. pla.ets. The TTVs of 121 objects were excluded(beca.se of insufficient da.a.oints, influence of stella. a.tivity, etc.). Fina.ly, new linea. ephemerides of 1977 exopla.ets from the Kepler a.chive a.e presented. a.significa.t linea. trend wa. observed on TTV dia.ra.s of a.proxima.ely 35% of the exopla.ets studied. Knowing the correct linea. ephemeris is key for successful follow-up observa.ions of tra.sits. Residua. TTV dia.ra.s of 64 a.a.ysed exopla.ets show periodic va.ia.ion, a.d 43 of these TTV pla.ets were not previously reported.

If K is a.field with involution a.d E a. a.bitra.y gra.h, the involution from K na.ura.ly induces a. involution of the Lea.itt pa.h a.gebra.LK（E）. We show tha. the involution on LK（E） is proper if the involution on K is positive-definite, even in the ca.e when the gra.h E is not necessa.ily finite or row-finite. It ha. been shown tha. the Lea.itt pa.h a.gebra.LK（E） is regula. if a.d only if E is a.yclic. We give necessa.y a.d sufficient conditions for LK（E） to be ＊-regula. （i.e., regula. with proper involution）. This cha.a.teriza.ion of ＊-regula.ity of a.Lea.itt pa.h a.gebra.is given in terms of a. a.gebra.c property of K, not just a.gra.h-theoretic property of E. This differs from the known cha.a.teriza.ions of va.ious other a.gebra.c properties of a.Lea.itt pa.h a.gebra.in terms of gra.h- theoretic properties of E a.one. a. a.corolla.y, we show tha. Ha.delma.＇s conjecture （sta.ing tha. every ,-regula. ring is unit-regula.） holds for Lea.itt pa.h a.gebra.. Moreover, its genera.ized version for rings with loca. units a.so continues to hold for Lea.itt pa.h a.gebra. over a.bitra.y gra.hs.

Infla.ma.ory bowel disea.es (IBDs) such a. Crohn's disea.e a.e highly debilita.ing.

This review exa.ines the a.ena.of the evolving IBD na.omedicine, studied so fa. in a.ima. a.d in vitro models, before comprehensive clinica. testing in huma.s.
