An Anglo-Saxon execution cemetery at Walkington Wold, Yorkshire [PDF]
This paper presents a re-evaluation of a cemetery excavated over 30 years ago at Walkington Wold in east Yorkshire. The cemetery is characterized by careless burial on diverse alignments, and by the fact that most of the skeletons did not have ...

Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

VERTEBRAL COLUMN OF MITHUN (Bos frontalis) - ITS BIOMECHANICS IN REFERENCE TO HABITAT ADAPTATION [PDF]
Vertebral columns of six adult healthy mithun, four male and two female were prepared by simple natural maceration process in water, and then they were cleaned with bleaching powder solution and sun dried.

Morphology and function of pinniped necks: The long and short of it
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.

Comparison of thoracic and lumbar erector spinae muscle activation before and after a golf practice session [PDF]
Lower back pain is commonly associated with golfers. The study aimed: to determine whether thoracic- and lumbar-erector-spinae muscle display signs of muscular fatigue after completing a golf practice session, and to examine the effect of the completed ...

Abstract Modularity and integration are key developmental properties and have remained central in evo‐devo research because of how they relate to evolvability. While modularity and integration have commonly been assessed with landmark‐based geometric morphometrics (GMM), other methods such as anatomical network analysis (AnNA) are increasingly being ...

Fluoroscopy-based navigation system in spine surgery [PDF]
The variability in width, height, and spatial orientation of a spinal pedicle makes pedicle screw insertion a delicate operation. The aim of the current paper is to describe a computer-assisted surgical navigation system based on fluoroscopic X-ray image calibration and three-dimensional optical localizers in order to reduce radiation exposure while ...

Paradoxical Activation of Entheseal Myeloid Cells by JAK1 and TYK2 Inhibitors via IL10 Antagonism
Background JAK inhibition (JAKi) is effective in seronegative spondyloarthropathy (SpA) spectrum disorders, but TYK2 inhibition failed in SpA spectrum ulcerative colitis, and tofacitinib showed minimal benefit in Crohn's Disease, which highlights the complex role for JAK‐STAT signaling in different inflammatory processes. In this study, we investigated

A New 3D Method to Segment the Lumbar Vertebral Bodies and to Determine Bone Mineral Density and Geometry [PDF]
In this paper we present a new 3D segmentation approach for the vertebrae of the lower thoracic and the lumbar spine in spiral computed tomography datasets. We implemented a multi-step procedure. Its main components are deformable models, volume growing, and morphological operations.
