Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet

The Cervical Vertebral Bone Quality Score Is a Novel Reliable Index Reflecting the Condition of Paraspinal Muscles and Predicting Loss of Cervical Lordosis After Open‐Door Laminoplasty

Orthopaedic Surgery, Volume 17, Issue 5, Page 1406-1417, May 2025.
There is a close correlation between C‐VBQ scores and the cervical deep extensors, deep flexors, and overall paraspinal muscles relative cross‐sectional area (RCSA) and degree of fat infiltration (DFF). The C‐VBQ score is a comprehensive parameter reflecting the quality of cervical bone and paraspinal muscles.

Accuracy Evaluation of a Novel Spinal Robotic System for Autonomous Laminectomy in Thoracic and Lumbar Vertebrae

Journal of Bone and Joint Surgery. American volume, 2023
Background: The main function of robots in spine surgery is to assist with pedicle screw placement. Laminectomy, which is as important as pedicle screw placement, lacks a mature robot-assisted system.

Modelling tri-cortical pedicle screw fixation in thoracic vertebrae under osteoporotic condition: A finite element analysis based on computed tomography

Comput. Methods Programs Biomed., 2020
BACKGROUND AND OBJECTIVE The technique of tri-cortical pedicle screw (TCPS) has been used to improve the anchoring strength in the sacral vertebrae. However, no studies have reported their application in the thoracic vertebrae.

Chondroblastoma of the thoracic vertebra

Journal of Clinical Neuroscience, 2001
A 48-year-old patient with interscapular pain was admitted to our clinic. MRI revealed a mass infiltrating the second thoracic vertebra and adjacent structures. No other clinical manifestations were observed in general examination. The patient underwent surgery and subtotal removal was achieved while anterior and posterior stabilisations were performed.

Thoracic vertebrae fracture: Is it an indicator of abdominal injury?

American Journal of Emergency Medicine, 2020
PURPOSE Traumatic vertebral fracture accounts for 10-15% of trauma related admissions. While the correlation between lumbar vertebral fractures and abdominal injuries is well established, the relationship between thoracic vertebral fractures (TVF) and ...

Biomechanical allometry in hominoid thoracic vertebrae

Journal of Human Evolution, 2009
Considerable differences in spinal morphology have been noted between humans and other hominoids. Although comparative analyses of the external morphology of vertebrae have been performed, much less is known regarding variations in internal morphology (density) and biomechanical performance among humans and closely related non-human primates.
