Background And Aims: Eocene foliage formerly attributed to the extant araliaceous genus Oreopanax was found attached to twigs bearing inflorescences and infructescences unlike those of Araliaceae. Using newly observable characters of phyllotaxy, vegetative and floral buds, infructescences and seeds, we sought to reassess the affinities of this strange angiosperm.
Methods: Fossils were studied from the Parachute Creek Member of the Green River Formation from near Bonanza, Utah and Douglas Pass, Colorado (ca.
Article Synopsis
- - Vaccinieae is a diverse group within the Ericaceae family, consisting of about 1430 species, primarily tropical, but well-known for temperate crops like blueberries and cranberries.
- - A phylogenomic study of 210 species revealed that Vaccinieae likely originated in temperate North America around 30 million years ago, with tropical species resulting from multiple migrations from these northern ancestors.
- - Findings indicate significant evolutionary events, including a unique ovary structure development and a major polyploid event, suggesting that Vaccinium's classification needs reevaluation due to its complex evolutionary history.
Background: Ultrasound beam aberration correction is vital when focusing ultrasound through the skull bone in transcranial magnetic resonance-guided focused ultrasound (tcMRgFUS) applications. Current methods make transducer element phase adjustments to compensate for the variation in skull properties (shape, thickness, and acoustic properties), but do not account for variations in the internal brain anatomy.
Purpose: Our objective is to investigate the effect of cerebrospinal fluid (CSF) and brain anatomy on beam focusing in tcMRgFUS treatments.
What Is Known And Objective: The rhabditid nematode Strongyloides stercoralis is the major causative agent of disseminated strongyloidiasis (DS). In rare cases, DS has caused enterococcal meningitis. If DS-associated vancomycin-resistant Enterococcus faecium (VRE) meningitis is suspected, combination antibiotic therapy should be considered.

The fossil record of Apocynaceae is relatively poor, and the distinctive floral characters of this family have not been recognized in the fossil record before.
Methods: Remains of tiny flowers in amber were studied by micro-CT scanning, reflected light, and epifluorescence microscopy.
