ROS‐Responsive Wedelolactone Hydrogel Promotes Intervertebral Disc Repair by Disrupting the NF‐κB–LCN2 Inflammatory Feedback Loop

open access: yesAdvanced Science, EarlyView.
A mechanically robust, ROS‐responsive hydrogel is engineered to treat intervertebral disc degeneration by targeting the NF‐κB–LCN2 inflammatory feedback loop. By delivering wedelolactone specifically within oxidative niches, this system disrupts macrophage–disc cell crosstalk.

Reverse engineering applied to a lumbar vertebra [PDF]

open access: yes, 2007
Bone studies can be made in vivo or in vitro. However, disadvantages of both traditional techniques call for a compromise between the two. Reverse engineering allows in vitro bone samples to be simulated and analysed in a virtual in vivo environment thus

Prognostic Utility of the Preoperative Cachexia Index in Patients Undergoing Emergency Laparotomy

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The preoperative cachexia index, incorporating muscle mass, nutritional status, and inflammation, predicts in‐hospital and one‐year mortality in patients undergoing emergency laparotomy. This simple index may aid in risk stratification and perioperative decision‐making in high‐risk surgical patients. ABSTRACT Aim Emergency laparotomy is associated with

2D-3D registration of CT vertebra volume to fluoroscopy projection: A calibration model assessment (doi:10.1155/2010/806094) [PDF]

open access: yes, 2010
This study extends a previous research concerning intervertebral motion registration by means of 2D dynamic fluoroscopy to obtain a more comprehensive 3D description of vertebral kinematics. The problem of estimating the 3D rigid pose of a CT volume of a

Impact of Body Weight Loss During Preoperative Chemoradiotherapy on Prognosis of Patients With Lower Rectal Cancer

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The present study aimed to investigate the relationship between changes in body weight and composition during chemoradiotherapy, such as the psoas muscle mass index, visceral fat index, and subcutaneous fat index obtained from computed tomography images, and long‐term outcomes in rectal cancer patients.

Radiological Investigation of Guinea Pig (Cavia porcellus) Lumbar Vertebral Morphology ‒ A Biomechanical Aspect

open access: yesActa Veterinaria, 2023
Numerous studies are based on the use of animal models; however, in bipedal and tetrapedal organisms there are significant differences in the biomechanics of the spinal column, which can significantly impair the quality and applicability of the results ...

Histological evidence for a supraspinous ligament in sauropod dinosaurs [PDF]

open access: yes, 2015
Supraspinous ossified rods have been reported in the sacra of some derived sauropod dinosaurs. Although different hypotheses have been proposed to explain the origin ofthis structure, histological evidence has never been provided to support or reject any

Psoas Muscle Volume as a Predictor of Postoperative Complications in Patients Undergoing Emergency Surgery for Strangulated Small Bowel Obstruction: A Retrospective Single‐Center Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This retrospective study identified low preoperative psoas muscle volume, measured by computed tomography, as an independent predictor of postoperative complications in patients undergoing emergency surgery for strangulated small bowel obstruction. Low psoas muscle volume, particularly in older adults, was associated with cardiopulmonary and systemic ...

Prognostic Value of Psoas Major Muscle Volume in Assessing Sarcopenia in Elderly Patients With Rectal Cancer

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study investigates the prognostic utility of a novel volumetric indicator—psoas volume index (PVI)—for assessing sarcopenia in elderly rectal cancer patients. Sarcopenia classified by our proposed PVI cut‐off values was associated with poor nutritional and inflammatory status, and patients with low PVI showed significantly worse long‐term outcomes.

A comparison of two techniques: Open and percutaneous biopsies of thoracolumbar vertebral body lesions

open access: yesJournal of Craniovertebral Junction and Spine, 2015
Aim: The purpose of this article is to compare the similarity of initial radiological diagnosis and pathological diagnosis between thoracal and lumbar vertebral bodies and the adequacy and the reliability of open and percutaneous biopsies performed via ...
