Background: Previous ultrasonographic studies of Sapajus apella to determine the normal anatomy and physiology are incomplete. The aim of this study was to determine normal ultrasonographic appearance and measurements of all abdominal organs and structures of interest.
Methods: Twelve adult monkeys were recruited considered healthy on the basis of history, physical examination, and general blood work. To avoid additional anesthesia, the ultrasonographic examinations were performed during routine screening, annually scheduled by the Unit of Cognitive Primatology & Primate Center, CNR-Rome, where the animals were housed. Ultrasound data were processed offline by two experienced ultrasonographers.
Results: Topography, morphology and echostructure were described for almost all organs and descriptive statistics were provided.
Conclusion: To the author's knowledge, this is the most complete ultrasonographic study in Capuchin monkeys.

Objective: To investigate the sonographic effects of alfaxalone and butorphanol alone and in combination on feline splenic size, shape, margins, echogenicity, echotexture, and blood flow. Our hypothesis was that alfaxalone alone and in combination would be associated with an increase in splenic size and blood flow and a nonhomogenous echotexture.
Methods: This was a randomized, prospective crossover study.
Long-term ultrasonographic changes of the canine prostate gland after castration.
Front Vet Sci

Department of Veterinary Medicine and Animal Production, University of Naples, Federico II, Naples, Italy.
Introduction: Ultrasound imaging (US) is the method of choice to assess the canine prostate gland. Whilst recent studies have documented the role of castration in the development of prostatic neoplasia, little is known about parenchymal and perfusion features of the normal and abnormal prostate in neutered dogs. No data are available concerning prostatic changes after the first 90 days following castration.

Aim: This study aims to evaluate the accuracy of ultrasonography (US) by comparing preoperative ultrasonographic findings with intraoperative observations during laparoscopic cholecystectomy (LC).
Materials And Methods: An observational analytical study was conducted at a tertiary hospital in Pune over two years and included 98 patients aged 20-80 with symptomatic cholelithiasis confirmed by US. Preoperative parameters assessed included gallstone number, gallbladder volume, wall thickness, and pericholecystic fluid.
Clinical efficacy of electrosurgery and steel scalpel surgery for umbilical herniorrhaphy in bovine calves: A comparative analysis.

Electrosurgery (ES) offers a promising alternative to conventional steel scalpel surgery (SSS), providing superior hemorrhage control and efficient tissue dissection with minimal invasiveness. Given the limited literature, this study aims to compare the clinical efficacy of ES with that of SSS in bovine umbilical herniorrhaphy. Fourteen crossbred male calves with reducible umbilical hernias, aged less than one month and weighing 25-47 kg, were randomly assigned to two experimental groups: group A (ES) and group B (SSS), each containing seven calves.
