Deep Learning Methods for Assessing Time‐Variant Nonlinear Signatures in Clutter Echoes

Advanced Intelligent Systems, EarlyView.
Motion classification from biosonar echoes in clutter presents a fundamental challenge: extracting structured information from stochastic interference. Deep learning successfully discriminates object speed and direction from bat‐inspired signals, achieving 97% accuracy with frequency‐modulated calls but only 48% with constant‐frequency tones.

Color doppler in diagnosis of pathological changes in blood vessels [PDF]

Praxis Medica, 2014
Color Doppler ultrasound is a method that allows noninvasive imaging of blood flow through a blood vessel and analysis of blood vessels, which can be made to flow disturbance and the presence of plaque and narrowing of the blood vessel.

Biocompatibility and healing patterns in experimentally induced canine tibial fractures using Pedicle screw‐Rod external fixation

Animal Models and Experimental Medicine, EarlyView.
This study demonstrates that using a Pedicle screw‐Rod configuration for the external fixation of non‐articular tibial osteotomy aligns well with the principles of biological osteosynthesis, resulting in secondary bone healing characterized by callus formation and neovascularization.

Renal vessel–assisted anastomosis improves the abdominal heart transplant model in rats without bilateral lower limb ischemia

Animal Models and Experimental Medicine, EarlyView.
A modified heterotopic heart transplantation (HTx) in rats was reported to improve the surgical success rate, in which the donor's vessels, the brachiocephalic trunk (BT) and the pulmonary artery (PA), were sutured to the recipient's left renal artery (RA) and left renal vein (RV).

Chronic high‐fat diet induces multi‐organ dysfunction and metabolic homeostasis disruption in Macaca fascicularis

Animal Models and Experimental Medicine, EarlyView.
An 18‐month HFD successfully established a translational Macaca fascicularis model replicating key metabolic disorders (MASH, diabetes, cardiac hypertrophy). MASH was determined by liver biopsy histology, the presence steatosis, inflammatory infiltration, hepatocytic ballooning, and fibrosis were considered as MASH; diabetes was diagnosed according to ...
