Novel conopeptides of the I-superfamily occur in several clades of cone snails [PDF]

, 2004
The I-superfamily of conotoxins represents a new class of peptides in the venom of some Conus species. These toxins are characterized by four disulfide bridges and inhibit or modify ion channels of nerve cells.

Pediatric spinal ependymomas: Long‐term surgical outcomes in a cohort of 61 cases

Pediatric Investigation, EarlyView.
Spinal ependymomas are rare in children, with limited long‐term outcome data. In this retrospective study of 61 pediatric patients undergoing surgical resection, gross total resection was achieved in 62.3% and was associated with favorable functional improvement. Recurrence was observed in 31.1% of cases.

Chiropractic spinal manipulative therapy versus physical therapist‐led exercise and the risk of cauda equina syndrome in adults with lumbar disc herniation, stenosis, or radiculopathy

PM&R, EarlyView.
Abstract Background Cauda equina syndrome is a surgical emergency often caused by lumbar disc herniation. Spinal manipulative therapy is commonly used for lumbar spine disorders, but case reports have raised concerns it may precipitate cauda equina syndrome. One cohort study suggested no increased risk, although it did not focus on patients with lumbar

Modulation of wind drag by tidal currents in an embayment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.
