Neurophysiological Recovery Following Nerve Transfer Surgery to Restore Upper Limb Function after Cervical Spinal Cord Injury

open access: yesAnnals of Neurology, EarlyView.
Objectives Nerve transfer is a promising intervention for restoring hand and upper limb function after cervical spinal cord injury (SCI), but the timeline of neurophysiological recovery in humans remains unclear. This study aimed to define recovery profiles after nerve transfers to restore upper limb function.

Nanodiamonds as Bioactive Platforms to Modulate Microbial, Mammalian, and Vertebrate Systems

open access: yesAdvanced NanoBiomed Research, EarlyView.
Nanodiamonds (NDs) are biocompatible and antibacterial nanomaterials that support mammalian cell growth while inhibiting bacterial pathogens. NDs showed strong antibacterial activity, with Escherichia coli being more sensitive than Staphylococcus aureus. At 10 mg/mL, both bacteria exhibited ~8% viability.

Piezoelectric Nanocomposite Hydrogel for Wireless Neural Stimulation and Tissue Augmentation

open access: yesAdvanced NanoBiomed Research, EarlyView.
A cell/tissue supporting piezoelectric hydrogel system (PZ‐gel) that incorporates ferroelectric, pyroelectric, and piezoelectric ceramic material barium titanate into an alginate/carboxymethyl chitosan hydrogel. The PZ‐gel can be sonoactivated for wireless neural cell and tissue stimulation, with the potential to be used as a stimulatory cell substrate

The mechanism of labor in nonhuman primates: A look inside

open access: yesThe Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Historical birth records from 1896 to 1944 from the Basel maternity hospital, Switzerland, reveal significant obstetric selection pressures

open access: yesThe Anatomical Record, EarlyView.
Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Craniofacial growth, modeling, and estimation of milestones

open access: yesThe Anatomical Record, EarlyView.
Abstract Understanding craniofacial growth is foundational for research into intra‐ and interspecies variation, evolution, and clinical care. The Craniofacial Growth Consortium Study (CGCS), combines cephalographs from historical growth studies to create a dense longitudinal record of growth from 6 to 22 years of age.

Nontobacco Nicotine Dependence Is Associated With Perioperative Complications and Repeat Surgery After Arthroscopic Rotator Cuff Repair

open access: yesArthroscopy, EarlyView.
Purpose To compare perioperative complications and revision surgery rates between following primary rotator cuff repair among patients with nontobacco nicotine dependence (NTND), no nicotine dependence, and traditional tobacco‐related nicotine dependence.

Resistance to Axial Traction Decreases Over Time Following Repaired Periportal Capsulotomies During Hip Arthroscopy

open access: yesArthroscopy, EarlyView.
Purpose To determine if distraction distance changes on an axial traction examination between the time zero capsular repair state and a later follow‐up traction examination in patients with staged bilateral hip arthroscopies for femoroacetabular impingement syndrome.
