Ring-shaped Dandy's superior petrosal vein

Mugurel Constantin Rusu, Mihai Lazar, Alexandra Diana Vrapciu

Summary: A previously unreported ring-shaped superior petrosal vein (RS-SPV) was found on the petrosal surface of the right cerebellar hemisphere. It was inserted in the superior petrosal sinus (SPS) above the internal auditory pore and located posterior-lateral to the trigeminal pore. The anterior arm of the venous ring received veins from the pontine surface and continued as a single venous trunk on the cerebellar surface.

Fourth lumbar artery continuation of the common iliac artery with a retro-psoas course demonstrated by CT

Cigdem Oztunali, Berat Acu

Summary: This case report describes an anomalous common iliac artery (CIA) that originated from the aorta as the fourth lumbar artery (4th LA) and followed a retro-psoas course. The patient was an 8-year-old girl and the anomaly was incidentally detected on abdominopelvic computed tomography (CT). Although mostly asymptomatic, knowledge of this vascular anomaly is important in interventions of the area to prevent complications.

Quercetin-targeted AKT1 regulates the Raf/MEK/ERK signaling pathway to protect against doxorubicin-induced nephropathy in mice

Yufang Wang, Mingfang Liu, Nan Huang, Tingting Wang

Summary: The study found that quercetin can promote the recovery of kidney function in kidney-injured mice. Histopathological results showed that kidney tissue damage and fibrosis were reduced under the action of quercetin. The mitochondrial swollen structure caused by doxorubicin was restored by quercetin. Quercetin regulated the levels of abnormal apoptotic proteins Bax and Bcl-2 to normal levels. The high expression of Ang II caused by doxorubicin was down-regulated by quercetin. Abnormal inflammatory factors caused by doxorubicin were reversed by quercetin. Western blot experiments showed that quercetin regulated the protein levels of AKT1 and Raf/MEK/ERK and inhibited the detrimental effects of doxorubicin.
