Uterine spiral artery muscle dedifferentiation
Human Reproduction, 2019 AbstractSTUDY QUESTIONIs vascular smooth muscle cell (VSMC) dedifferentiation a feature of uterine spiral artery (SpA) remodelling in early human pregnancy?SUMMARY ANSWERRemodelling of human uterine SpAs is associated with dedifferentiation of VSMCs and can be induced in vitro by uterine natural killer (uNK) cells and extravillous trophoblast cells ...

Gender differences in myogenic regulation along the vascular tree of the gerbil cochlea. [PDF]
PLoS ONE, 2011 Regulation of cochlear blood flow is critical for hearing due to its exquisite sensitivity to ischemia and oxidative stress. Many forms of hearing loss such as sensorineural hearing loss and presbyacusis may involve or be aggravated by blood flow ...

Successful Bail-Out Stenting for Iatrogenic Right Coronary Artery Dissection in a Young Male
JACC: Case Reports, 2019 Catheter-induced coronary artery dissection is a serious complication of coronary angiography. Percutaneous intervention is usually indicated in case of large spiral dissections, however, wiring into the true lumen can be challenging.

Inhibition of Trophoblast-Induced Spiral Artery Remodeling Reduces Placental Perfusion in Rat Pregnancy. [PDF]
, 2010 Rats harboring the human angiotensinogen and human renin genes develop preeclamptic features in pregnancy. The preeclamptic rats exhibit a deeper trophoblast invasion associated with a reduced resistance index by uterine Doppler.

Interleaved spiral cine coronary artery velocity mapping [PDF]
Magnetic Resonance in Medicine, 2000 Navigator-echo controlled interleaved spiral cine coronary-artery velocity maps were acquired in eight free-breathing volunteers. Good quality data were achieved in all subjects with phasic flow being clearly demonstrated. The improved efficiency of spiral k-space coverage compared to that of more conventional spin-warp techniques resulted in a mean ...

Impaired decidual natural killer cell regulation of vascular remodelling in early human pregnancies with high uterine artery resistance [PDF]
, 2012 During human pregnancy, natural killer (NK) cells accumulate in the maternal decidua, but their specific roles remain to be determined. Decidual NK (dNK) cells are present during trophoblast invasion and uterine spiral artery remodelling.
