Osseointegration of Self-Drilling Titanium Screws in the Hole Smaller than the Screw Core in the Male Rabbit

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Veterinary Medicine
Inserting orthopedic screws into a hole that is too small can produce excessive mechanical forces that cause osteocyte death and difficulty carrying out bone repair processes. The aim of the study was to evaluate the osseointegration of titanium screws 6

Long‐Term Memory Updating Parallels Altered Awake and Sleep Hippocampal Replays

open access: yesAdvanced Science, EarlyView.
This study introduces a behavioral paradigm for memory updating and reveals underlying hippocampal mechanisms. Replays of place cells predict future behavioral choices during behavior and show a bias toward high‐reward locations during non‐rapid eye movement (NREM) sleep, specifically within the memory updating process.

The influence of “kickstand” screws on the mechanical performance of a lateral distal femoral plate: a finite element analysis

open access: yesBone & Joint Research
Aims: Lateral locked plating of distal femoral fractures is widely reported, yet there remains a 9% to 19% incidence of mechanical failure. Obliquely directed “kickstand screws”, from the metaphyseal portion of a plate toward far-sided articular ...

Spinal involvement in mucopolysaccharidosis IVA (Morquio-Brailsford or Morquio A syndrome): presentation, diagnosis and management. [PDF]

open access: yes, 2013
Mucopolysaccharidosis IVA (MPS IVA), also known as Morquio-Brailsford or Morquio A syndrome, is a lysosomal storage disorder caused by a deficiency of the enzyme N-acetyl-galactosamine-6-sulphate sulphatase (GALNS). MPS IVA is multisystemic but manifests

Cortico‐Striatal‐Midbrain Circuit Dysregulation Underlying MK‐801 Induced Impulsivity and the Ameliorative Effects of SEP

open access: yesAdvanced Science, EarlyView.
Impulsivity is a symptom across multiple psychiatric disorders, yet its neural basis remains elusive. This study shows that the NMDAR antagonist MK‐801 elevates dopamine release and disrupts neuronal selectivity in the nucleus accumbens, leading to impulsive behavior.

Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

open access: yesAdvanced Science, EarlyView.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

Comparison and prediction of pullout strength of conical and cylindrical pedicle screws within synthetic bone

open access: yesBMC Musculoskeletal Disorders, 2009
Background This study was designed to derive the theoretical formulae to predict the pullout strength of pedicle screws with an inconstant outer and/or inner diameter distribution (conical screws).

Deciphering Neural Mechanisms Underlying Marmoset Dynamic Natural Behaviors Using a Miniaturized Wireless Large‐Scale Coverage Neural Recorder

open access: yesAdvanced Science, EarlyView.
This study introduces a miniaturized wireless neural recording system integrated with custom‐designed 120‐channel µECoG arrays, engineered for monitoring brain activities in freely behaving marmosets. The system can capture and characterize behavior‐specific neural signals, including drinking‐related activation, pre‐vocalization anticipatory responses,
