Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

open access: yesJournal of Anatomy, EarlyView.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

Risk factors of early subsidence of 3D-printed artificial vertebral body following single-level anterior cervical corpectomy and fusion (ACCF): retrospective study of 98 patients

open access: yesJournal of Orthopaedic Surgery and Research
Background The 3D-printed artificial vertebral body (AVB) was designed with theoretically better biomechanical properties than traditional implants to decrease the incidence of implant subsidence.

Changes in the Pterygopalatine and Midpalatal Sutures After Rapid Palatal Expansion With Tooth‐Bone‐Borne (MARPE) and Tooth‐Borne (Hyrax) Appliances

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This retrospective cohort study aimed to compare the effects of tooth‐bone‐borne mini‐implant‐assisted rapid palatal expansion (MARPE) and tooth‐borne (Hyrax) rapid palatal expansion (RPE) techniques on the pterygopalatine suture (PPS) and the opening pattern of the midpalatal suture (MPS).

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

open access: yesOrthopaedic 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.

Keyhole Foraminotomy Combined With Unilateral Laminotomy for Bilateral Decompression Under Biportal Endoscopic Spinal Surgery for the Treatment of Mixed‐Type Cervical Spondylosis

open access: yesOrthopaedic Surgery, EarlyView.
Under biportal endoscopic spine surgery, one‐stage decompression combining keyhole foraminotomy and unilateral laminotomy for bilateral decompression (ULBD) for mixed‐type cervical spondylopathy can achieve favorable clinical outcomes with minimal compromise of spinal stability.

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

open access: yesExperimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

open access: yesExperimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

open access: yesExperimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...
