SPIRAL ARTERIES IN THE HUMAN OVARY
Obstetrical & Gynecological Survey, 1948Occasionally it happens that a scientific observation is made only to be forgotten and rediscovered after a long period of time. When it is rediscovered, it may be remembered because its significance is appreciated in the light of newly acquired knowledge.

Spiral Looping of Retinal Artery
Journal of Pediatric Ophthalmology & Strabismus, 1977An isolated retinal vascular anomaly in the form of an arterial loop is presented in a 32-year-old male. This loop originated on the retina beyond the optic disc border and returned to the lower branch of the central artery on the retinal tissue after making six spirals.

Fast Spiral Coronary Artery Imaging
Magnetic Resonance in Medicine, 1992AbstractA flow‐independent method for imaging the coronary arteries within a breath‐hold on a standard whole‐body MR imager was developed. The technique is based on interleaved spiral k‐space scanning and forms a cardiac‐gated image in 20 heartbeats. The spiral readouts have good flow properties and generate minimal flow artifacts.

Extracellular ATP decreases trophoblast invasion, spiral artery remodeling and immune cells in the mesometrial triangle in pregnant rats [PDF]
Placenta, 2014 Introduction: Preeclampsia is characterized by deficient trophoblast invasion and spiral artery remodeling, a process governed by inflammatory cells. High levels of the danger signal extracellular adenosine triphosphate (ATP) have been found in women ...

Spiral artery remodeling and maternal cardiovascular risk
Journal of Hypertension, 2016Women with a history of placental bed disorders, including preeclampsia and intrauterine growth restriction have an increased long-term risk of cardiovascular disease (CVD). Further, similarities exist between atherosclerosis and abnormalities observed in placental bed spiral arteries in pregnancies affected by preeclampsia and intrauterine growth ...

A spiral artery in the ovary of the rabbit
American Journal of Obstetrics and Gynecology, 1947Abstract A spiral artery within the hilus of the ovary is demonstrated. It is formed by a helix-type of formation from the ovarian artery as it enters the hilus of the ovary and turns sharply cephalad. Further vascularization of the ovary is accomplished by secondary branches arising from the coils of the spiral artery.

Endovascular trophoblast and spiral artery remodeling
Molecular and Cellular Endocrinology, 2020Spiral artery remodeling, which is indispensable for successful pregnancy, is accomplished by endovascular trophoblasts that move upstream along the arterial wall, replace the endothelium, and disrupt the muscular lining. This review outlines the possible factors that could regulate endovascular trophoblast differentiation and invasion.

Trophoblast plugs: impact on utero-placental haemodynamics and spiral artery remodelling [PDF]
Human Reproduction, 2018 STUDY QUESTION:How does trophoblast plugging impact utero-placental haemodynamics? SUMMARY ANSWER:Physiological trophoblast plug structures are dense enough to restrict flow of oxygenated blood to the intervillous space (IVS) in the first trimester, and ...

Spiral laminar flow in arteries?
The Lancet, 1991Spiral blood-flow patterns in infrainguinal blood-vessels were observed at angioscopy in 54 patients who underwent peripheral vascular reconstruction; the endoluminal surface had spiral folds in 51 of 75 arteries examined. Spiral flow patterns, congruous with inherent endoluminal anatomical features, might more accurately represent blood-flow in ...

Coronary artery motion compensation in spiral CT
SPIE Proceedings, 2005Because of motion artifacts, spiral Computer Tomography (CT) is not presently a widely useful diagnostic tool in cardiac imaging. There are two time scales in CT data acquisition. The first is the time-scale of a single projection which is roughly a half millisecond.
