Enhanced myocardial perfusion in late gestation fetal lambs with impaired left ventricular inflow.
J Physiol

Center for Developmental Health, Oregon Health & Science University, Portland, OR, USA.
Robust preclinical models of asymmetric ventricular loading in late gestation reflecting conditions such as hypoplastic left heart syndrome are lacking. We characterized the morphometry and microvascular function of the hypoplastic left ventricle (LV) and remaining right ventricle (RV) in a sham-controlled late gestation fetal lamb model of impaired left ventricular inflow (ILVI). Singleton fetuses were instrumented at ∼120 days gestational age (dGA; term is ∼147 days) with vascular catheters, an aortic flow probe and a deflated left atrial balloon.

Pemetrexed is a chemotherapeutic, antimetabolite agent that has been used in oncology to treat diseases such as metastatic non-small cell lung cancer and unresectable malignant pleural mesothelioma. Pemetrexed use may result in pseudocellulitis, which presents as poorly demarcated patches or plaques with erythema, edema, warmth, and tenderness. These lesions can present unilaterally or bilaterally on the lower extremities.

McKnight Brain Institute, University of Florida, Gainesville, FL, USA.
Study Design: Experimental Animal Study.
Objective: To continue validating an antibody which targets an epitope of neurofilament light chain (NF-L) only available during neurodegeneration and to utilize the antibody to describe the pattern of axonal degeneration 10 days post-unilateral C4 contusion in the rat.
Setting: University of Florida laboratory in Gainesville, USA.
Pulmonary hypertension in infancy: a reversible cause.
BMJ Case Rep
January 2025
Pediatrics, The University of Tennessee Health Science Center, Memphis, Tennessee, USA.
A term, healthy infant presented with respiratory distress and severe pulmonary hypertension (PH). With an unclear aetiology and the intent to decrease right ventricular afterload, pulmonary vasodilators were initiated. Follow-up imaging revealed a supravalvular mitral ring as the cause of the PH which resolved after surgical resection of the membrane.

This study aimed to identify radiotherapy dosimetric parameters related to local failure (LF)-free survival (LFFS) in patients with lung and liver oligometastases from colorectal cancer treated with stereotactic body radiotherapy (SBRT). We analyzed 75 oligometastatic lesions in 55 patients treated with SBRT between January 2014 and December 2021. There was no constraint or intentional increase in maximum dose.
