The Colour Changes In Lizards, Particularly In Phrynosoma [PDF]

open access: yes, 1938
The activities of the melanophore system of Phrynosoma in comparison with that of Chamaeleo may be stated categorically in the following way. I. The blanching of Phrynosoma blainvillii is due (1) to the action of its concentrating nerve-fibres on ...

Conduction abnormalities are restricted to the central nervous system in experimental autoimmune encephalomyelitis induced by inoculation with proteolipid protein but not with myelin basic protein [PDF]

open access: yes, 1994
Experimental autoimmune encephalomyelitis (EAE) is an inflammatory demyelinating disease of the central nervous system (CNS) and can be induced by inoculation of animals with homogenized CNS tissue or highly purified myelin proteins such as myelin basic ...

Anatomical Study of Lateral Compression II Screw Path and Entry Parameters Based on Three‐Dimensional CT Image Reconstruction Techniques

open access: yesOrthopaedic Surgery, Volume 17, Issue 5, Page 1454-1463, May 2025.
This graphical abstract illustrates a study where 43 adult patients (21 males, 22 females) underwent CT scans to reconstruct 3D pelvic models using Mimics and 3‐Matic software. The analysis measured the Lateral Compression II (LC‐II) screw path, revealing sex‐based anatomical differences that could improve the precision and safety of percutaneous LC‐II

Lumbar artery perforator (LAP) flap: a salvage tool for extended lumbo-sacral necrosis after bilateral internal iliac arteries embolization. [PDF]

open access: yes, 2016
We report the case of a 52-year-old man presenting an extensive lumbosacral necrosis after bilateral internal iliac arteries embolization following unstable pelvic fracture. Coverage of the defect was performed using two extended lumbar artery perforator

Biomechanical Analysis and Injury Prediction in Pilots With Lumbar Spondylolysis Under Different Seat Inclination Angles

open access: yesJOR SPINE, Volume 9, Issue 1, March 2026.
The biomechanical responses of three lumbar models under both seat angles remain below injury thresholds. However, the occurrence of spondylolysis at a 22° angle poses a higher risk. ABSTRACT Background This study aims to quantify the biomechanical effects of different seat inclinations on the normal and spondylolysis lumbar of pilots under typical ...

Development of a Grasshopper‐Leg‐Inspired Back‐Type Exoskeleton for the Reduction of Muscle Activation During Stoop Activities

open access: yesJournal of Field Robotics, Volume 43, Issue 2, Page 739-760, March 2026.
ABSTRACT Farmers frequently suffer from musculoskeletal disorders, particularly lower back pain (LBP), mainly due to occupational ergonomic factors such as repetitive stooping and lifting. This study proposes using an exoskeleton to reduce LBP risk by providing external torque to the hip joints.

Foxp1 and lhx1 coordinate motor neuron migration with axon trajectory choice by gating Reelin signalling. [PDF]

open access: yes, 2010
Topographic neuronal maps arise as a consequence of axon trajectory choice correlated with the localisation of neuronal soma, but the identity of the pathways coordinating these processes is unknown.
