Myocardial strain assessment in the human fetus by cardiac MRI using Doppler ultrasound gating and feature tracking.

Objectives: Assessment of myocardial strain by feature tracking magnetic resonance imaging (FT-MRI) in human fetuses with and without congenital heart disease (CHD) using cardiac Doppler ultrasound (DUS) gating.

Methods: A total of 43 human fetuses (gestational age 28-41 weeks) underwent dynamic cardiac MRI at 3 T. Cine balanced steady-state free-precession imaging was performed using fetal cardiac DUS gating.

Posttraumatic Amputations Epidemiology and Outcomes Within the National Trauma Data Bank: Improved Survival Over Time Results in Increased Population in Need of Rehabilitation Support.

Objective: Acute trauma care has significantly reduced mortality over the last two decades. The last study to examine the epidemiology of traumatic amputees predates these gains. The majority of those who sustain traumatic amputation are male; therefore, limited data exist on female amputees.

Fetal 4D flow MRI of the great thoracic vessels at 3 Tesla using Doppler-ultrasound gating: a feasibility study.

Objectives: To evaluate the feasibility of Doppler-ultrasound (DUS)-gated 4D flow MRI of the fetal great thoracic vessels at 3T in a clinical setting.

Methods: Sixteen consecutive fetuses (range 30-38 weeks) with (n = 11) and without (n = 5) cardiovascular anomalies underwent 4D flow MRI of the great thoracic vessels at 3T. Direct fetal cardiac gating was obtained using a MR-compatible DUS device.

Effects of systemic pretreatment with CpG oligodeoxynucleotides on skin wound healing in mice.

Unmethylated CpG oligodeoxynucleotides (ODN) bind to the Toll-like receptor 9, thus stimulating the immune system. To study the effects of systemic pretreatment with CpG ODN on dermal regeneration, C57BL6/J Tyr mice were treated with CpG or control ODN 6 days prior to implantation of a dorsal skinfold chamber and skin wounding. Wound epithelialization was analyzed by planimetric microscopy.
