Infanticide in Chimpanzees: Taphonomic Case Studies from Gombe [PDF]

open access: yes, 2017
Objectives We present a study of skeletal damage to four chimpanzee (Pan troglodytes) infanticide victims from Gombe National Park, Tanzania. Skeletal analysis may provide insight into the adaptive significance of infanticide by examining whether ...

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.

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 ...

Homozygous Achondroplasia With Long‐Term Survival: Growth Patterns, Medical Interventions, and Practice Implications

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Homozygous achondroplasia is widely considered perinatal lethal by the medical community. In this case series, we report two children from a single family with longer‐term survival. One child lived for 17 months and the other was 60 months at the time of publication.

Effect of Lowest Instrumented Vertebra on Trunk Mobility in Patients With Adolescent Idiopathic Scoliosis Undergoing a Posterior Spinal Fusion [PDF]

open access: yes, 2014
Study Design Prospective. Objectives The goal of this study was to evaluate the effect of posterior spinal fusion surgery terminating at different lowest instrumented vertebrae (LIV) on trunk mobility in individuals with adolescent idiopathic scoliosis (

Compression suture: A method for simulating intervertebral disc degeneration in rats induced by excessive loading

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In the compression suture group, a 5‐mm‐wide tail skin was removed, and then the defect was sutured to apply compressive force to the intervertebral disc. In the sham group, only the 5‐mm‐wide tail skin was removed without a compression suture. Compression suturing triggers apoptosis, inflammatory response, and imbalance of extracellular matrix ...

Automatic Lumbar Vertebrae Segmentation in Fluoroscopic Images via Optimised Concurrent Hough Transform

open access: yes, 2001
Low back pain is a very common problem in the industrialised countries and its associated cost is enormous. Diagnosis of the underlying causes can be extremely difficult. Many studies have focused on mechanical disorders of the spine.
