Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

open access: yesAdvanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Targeting Adipose Tissue Function Protects Against Heart Failure with Preserved Ejection Fraction

open access: yesAdvanced Science, EarlyView.
This study explores the role adipose tissue (AT) phenotypes have in determining cardiovascular outcomes in an obesity‐related heart failure with preserved ejection fraction (HFpEF) model. Pharmacological induction of thermogenesis promoted resilience to HFpEF‐induced remodeling of AT and conferred cardioprotection. Surgical and genetic models confirmed

Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

open access: yesAdvanced Science, EarlyView.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.

Conservative management of pubertal segmental testicular infarction associated with epididymitis

open access: yesUrology Case Reports, 2023
Urgent scrotal exploration is performed for segmental testicular infarction (STI) because malignant testicular tumors cannot be ruled out even when STI is suspected on color Doppler ultrasound (US). This report describes the case of a 14-year-old boy who

Ovarian hyperthecosis on grayscale and color Doppler ultrasound [PDF]

open access: yesUltrasound in Obstetrics & Gynecology, 2008
AbstractObjectivesTo describe the grayscale and color Doppler ultrasound findings in women with ovarian hyperthecosis.MethodsIn a retrospective study, we reviewed the findings on ultrasound examination of the ovaries in 10 patients with proven hyperthecosis. Clinical features had been recorded and testosterone levels measured in all cases.
