Blind-ending bifid ureter – a case report of rare congenital anomaly and its sonographic appearance

Journal of Ultrasonography, 2022
We report a case of a blind-ending bifid ureter in a 67-year-old woman with ascites initially diagnosed with B-mode and Color Doppler ultrasonography and afterwards verified with contrast-enhanced abdominal computed tomography. A literature review of the

Retrocaval Ureter: Report of Two Cases and Literature Review

Kaohsiung Journal of Medical Sciences, 2003
Retrocaval ureter is a rare congenital anomaly in which the ureter passes behind, and is compressed by, the inferior vena cava. Its etiology is assumed to be abnormal embryologic development of the inferior vena cava as a result of atrophy failure of the

Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

Advanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...

Gram‐Scale Synthesis of Hafnium‐Rich Carbon Dots for Preclinical Computed Tomography Imaging Across Various Systems

Advanced Science, EarlyView.
Hafnium (Hf)‐rich carbon dots (Hf‐rCDs) with high metal content (40.7%) and robust batch production capacity (>2 g per batch) are synthesized via a facile air‐assisted pyrolysis method. In vivo CT imaging demonstrates outstanding performance of Hf‐rCDs across multiple physiological systems and enables high‐resolution visualization of swine cervical ...

TRAP5 Inhibition Targeting Scar‐Associated Macrophages Ameliorates Acute Kidney Injury to Chronic Kidney Disease Transition

Advanced Science, EarlyView.
This study delineates macrophage heterogeneity along the acute kidney injury to chronic kidney disease transition. Single‐cell RNA sequencing reveals a TRAP5+ scar‐associated macrophage subset driven by Spp1–Cd44 signaling and mitochondrial metabolic reprogramming.

Multimodal AI‐Driven Identification of Dehydrocostus Lactone as a Potent Renal Fibrosis Attenuator Targeting IQGAP1

Advanced Science, EarlyView.
Renal fibrosis, a hallmark of CKD, lacks effective treatments. Herein, we developed a multimodal AI model (TCM‐SPred) to identify anti‐fibrotic agents and found that dehydrocostus lactone (DCL) targets IQGAP1 to inhibit Wnt signaling, blocking the interaction between IQGAP1 and CCT3, demonstrating potent anti‐fibrotic activity in vitro and in vivo ...

Experience With Surgical Correction of Retrocaval Ureter: A Report of Two Cases From Northern Tanzania. [PDF]

Clin Case Rep
Two adults with flank pain were diagnosed with a retrocaval ureter on CT showing a characteristic fishhook deformity and hydroureteronephrosis. Open pyeloureterostomy with anterior ureteral transposition resulted in an uneventful recovery and preserved renal function.

Novel Vascular‐Adaptive Liquid Metal Microspheres Enable Visualized Arterial Embolization Therapy

Advanced Science, EarlyView.
We present drug‐loaded liquid metal microspheres (X‐MEN) as a novel agent for image‐guided arterial embolization. With inherent radiopacity and superior deformability, X‐MEN enables real‐time monitoring and conforms tightly to irregular vessels. This approach ensures precise, long‐lasting embolization without recanalization, addressing critical ...
