Wireless, Adaptable and Fully Implantable Battery‐powered Devices for Optical Stimulation of the Spinal Cord in Small Rodents

Advanced Science, EarlyView.
Current technologies for spinal cord optogenetic stimulation rely on external power sources and face reliability constraints in freely behaving animals. Here, a fully implantable, battery‐powered optoelectronic device is introduced, enabling operation in any selected environment with wireless recharging for months‐long stimulation.

Spectrum of Congenital Anomalies in Myhre Syndrome—Insights Into Effects Brought by Altered TGF‐β Signaling via Gain‐of‐Function Variants in SMAD4

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome is a rare genetic disorder characterized by progressive multisystem involvement. Gain‐of‐function missense heterozygous variants affecting the Ile500 residue and Arg496 residue of the SMAD4 gene are implicated in this condition.

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

The Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

The Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Contribuição ao estudo das malformações occipito-cervical, particularmente da impressão basilar

Arquivos de Neuro-Psiquiatria, 1952
The authors outline the development of the spine and skull, particularly of axis, atlas and occipital bone. As neuro-skeletal dysmorphisms, the occipito-cervical malformations belong to the neurodysplastic group. They are classified as skeletal anomalies,

A computed tomographic morphometric analysis of the odontoid process for using anterior double Herbert screws fixation in the Southeast Asian population

Interdisciplinary Neurosurgery, 2022
Objective: To conduct a radiographic CT scan study of the axis (C2 vertebra) of the cervical spine in the Southeast Asian population was analyzed to evaluate the feasibility of fitting two 3.0-mm anterior odontoid screws.

Why sauropods had long necks; and why giraffes have short necks [PDF]

, 2012
The necks of the sauropod dinosaurs reached 15 m in length: six times longer than that of the world record giraffe and five times longer than those of all other terrestrial animals.
