In ovo time-lapse analysis after dorsal neural tube ablation shows rerouting of chick hindbrain neural crest [PDF]

, 2000
Previous analyses of single neural crest cell trajectories have suggested important roles for interactions between neural crest cells and the environment, and amongst neural crest cells. To test the relative contribution of intrinsic versus extrinsic

3D‐Printed Shark‐Inspired Soft–Hard Hybrid Underwater Robot With Buoyancy Control and Onboard Vision

Advanced Intelligent Systems, EarlyView.
A fully self‐contained shark‐inspired underwater robot is developed using 3D‐printed soft–hard hybrid structures, servo‐driven propulsion, and pump‐based buoyancy control. The platform achieves three‐dimensional locomotion and onboard vision‐based target tracking, offering a reproducible and accessible framework for biomimetic underwater robot research.

A comparative study of clonidine and dexmedetomidine as an adjuvant to levobupivacaine for caudal analgesia in children undergoing below umbilical surgeries: A randomized double-blind controlled trial

Ağrı
Objectives: Dexmedetomidine and clonidine have been studied separately as adjuvants with levobupivacaine, but there is no literature comparing the two drugs for caudal anesthesia in children.

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

Animal 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 ...

Wireless blood pressure sensor implantation in sheep: A detailed technique

Animal Models and Experimental Medicine, EarlyView.
Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.

Segmental migration of trunk neural crest: time-lapse analysis reveals a role for PNA-binding molecules [PDF]

, 1995
Trunk neural crest cells migrate through the somites in a striking segmental fashion, entering the rostral but not caudal sclerotome, via cues intrinsic to the somites.

A novel mouse model simulating C5 palsy after cervical surgery

Animal Models and Experimental Medicine, EarlyView.
This study establishes a reliable mouse model of permanent C5 palsy (post‐laminectomy complication) via dorsal approach, selectively severing the C5 anterior nerve root while preserving the posterior root through partial C4 and C5 laminectomy. The model successfully replicates clinical C5P features—flaccid shoulder paralysis, electrophysiological ...

Auditory Hyperresponsivity in Chronic Back Pain: A Randomized Controlled Trial of Pain Reprocessing Therapy

Annals of Neurology, EarlyView.
Objective Heightened sensitivity to noxious stimulation is a hallmark of chronic pain. Emerging evidence suggests heightened unpleasantness to non‐noxious (eg, auditory) aversive stimulation also characterizes chronic pain, but its magnitude, neural mechanisms, and treatment modifiability remain unknown.

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

The Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...
