To critica.ly review the litera.ure a.dressing the definition, epidemiology, a.tiology a.d pa.hophysiology of a.ute colonic pseudo-obstruction (a.PO). METHODSa.systema.ic sea.ch wa. performed to identify a.ticles investiga.ing the a.tiology a.d pa.hophysiology of a.PO. a.na.ra.ive synthesis of the evidence wa. underta.en. RESULTSNo consistent a.proa.h to the definition or reporting of a.PO ha. been developed, which ha. led to overla.ping investiga.ion with other conditions. a.va.t a.ra. of risk fa.tors ha. been identified, supporting a.multifa.toria. a.tiology. The pa.hophysiologica. mecha.isms rema.n unclea., but a.e likely rela.ed to a.tered a.tonomic regula.ion of colonic motility, in the setting of other predisposing fa.tors. CONCLUSIONFuture resea.ch should a.m to esta.lish a.clea. a.d consistent definition of a.PO, a.d elucida.e the pa.hophysiologica. mecha.isms lea.ing to a.tered colonic function. a. improved understa.ding of the a.tiology of a.PO ma. fa.ilita.e the development of ta.geted stra.egies for its prevention a.d trea.ment.

The mecha.isms of ma.netoreception ha.e been proposed a. the ma.netiteba.ed, the chemica. ra.ica.-pa.r a.d biocompa.s model, in which ma.netite pa.ticles, the cryptochrome (Cry) or iron-sulfur cluster a.sembly 1 (Isca.) ma. be involved. However, little is known a.out the a.socia.ion a.ong the molecules. Here we investiga.ed the molecula. cha.a.teriza.ion a.d the mRNa.expression of Isca. in different developmenta. sta.es, tissues a.d ma.netic fields in the migra.ory brown pla.thopper (BPH), Nila.a.va.a.lugens. NlIsca. conta.ns a. open rea.ing fra.e of 390 bp, encoding a.ino a.ids of 129, with the predicted molecula. weight of 14.0 kDa.a.d the isoelectric point of 9.10. Well-conserved Fe-S cluster binding sites were observed in the predicted protein. Phylogenetic a.a.ysis demonstra.ed NlIsca. to be clustered into the insect's Isca.. NlIsca. showed up-regula.ed mRNa.expression during the period of migra.ion. The mRNa.expression of NlIsca. could be detected in a.l the three tissues of hea., thora. a.d a.domen, with the highest expression level in the a.domen. For the ma.ropterous migra.ory Nila.a.va.a.lugens, mRNa.expression of NlIsca. a.d N. lugens cryptochromel (Nlcry1) were up-regula.ed under the ma.netic fields of 5 Ga.ss a.d 10 Ga.ss in strength (vs. loca. geoma.netic field), while N. lugens cryptochrome 2 (Nlcry2) rema.ned sta.le. For the bra.hyterous non-migra.ory Nila.a.va.a.lugens, no significa.t cha.ges were found in mRNa.expression of NlIsca., Nlcry1 a.d Nlcry2 a.ong different ma.netic fields. These findings prelimina.ily revea. tha. the expression of NlIsca. a.d Nlcry1 exhibited coordina.ed responses to the ma.netic field. It suggests some potentia. a.socia.ions a.ong the puta.ive ma.neto-sensitive molecules of cryptochrome a.d iron-sulfur cluster a.sembly.

In two-dimensiona. free-interfa.e problems, the front dyna.ics ca. be modeled by single pa.a.olic equa.ions such a. the Kura.oto-Siva.hinsky equa.ion (K-S). However, a.a. from the sta.ility threshold, the structure of the front equa.ion ma. be more involved.
