Alpha adrenergic receptors in renal pelvis and calyces: can rat models be used?

International Brazilian Journal of Urology, 2014
We aimed, in this study, to determine the distribution of α-1 AR subtypes in rat and human pelvis and calyces, and to evaluate, by comparing these two species, the possibility of rats to be used as models for humans.

A Robotic Urinary Bladder Enabling Volume Monitoring and Assisted Micturition

Advanced Intelligent Systems, EarlyView.
An implantable robotic bladder is presented that can store urine in an origami‐designed enclosure. An inductance sensing principle can monitor and transfer the urine volume in real‐time. It can actively expand based on the amount of urine collected from kidneys and apply on‐demand mechanical compression to assist urination.

Ultra‐Efficient Kidney Stone Fragment Removal via Spinner‐Induced Synergistic Circulation and Spiral Flow

Advanced Intelligent Systems, EarlyView.
Leveraging spinning‐induced localized suction, the spinner device enables ultra‐efficient removal of kidney stone fragments, capturing a larger quantity of fragments from distances exceeding 20 mm. The spinner significantly improves the efficiency and effectiveness of stone fragment removal by reducing operative time, increasing stone‐free rates, and ...

Challenges of modeling pristane‐induced lupus in non‐human primates

Animal Models and Experimental Medicine, EarlyView.
Systemic lupus erythematosus (SLE) in cynomolgus monkeys was modeled by two intraperitoneal injections of pristane at a dose of 3.5 mL/kg, administered at weeks 1 and 23. Serum samples from all monkeys that received pristane tested positive for antinuclear antibodies.

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of
