An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

open access: yesThe Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Evaluation of a waistband for attaching external radiotransmitters to anurans

open access: yesWildlife Society Bulletin, 2015
Radiotelemetry provides fine‐scale temporal and spatial information about an individual's movements and habitat use; however, its use for monitoring amphibians has been restricted by transmitter mass and lack of suitable attachment techniques.

Determining the effects of cattle grazing treatments on Yosemite toads (Anaxyrus [=Bufo] canorus) in montane meadows.

open access: yesPLoS ONE, 2013
Amphibians are experiencing a precipitous global decline, and population stability on public lands with multiple uses is a key concern for managers. In the Sierra Nevada Mountains (California, USA), managers have specifically identified livestock grazing

Can environmental DNA be used to detect first arrivals of the cane toad, Rhinella marina, into novel locations?

open access: yesEnvironmental DNA, 2020
Eradicating invasive species is difficult, but success is more likely when populations are small after arrival. The cane toad, Rhinella marina, is an invasive pest species that threatens native fauna worldwide.

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.

ANK1 and EPB41 Variants and The Risk of Glucocorticoid‐Induced Osteonecrosis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Steroid‐induced osteonecrosis of the femoral head (SONFH) is a refractory skeletal disorder influenced by genetic and environmental factors. However, conclusive pathogenic genetic evidence remains elusive due to the limited exploration of rare damaging variants. In this study, we aimed to identify rare variants associated with SONFH.

Integration of the arts and biomedical engineering in innovative interdisciplinary anatomy education: The synthetic anatomy module

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The intersection of science and art has historically fostered innovation, yet the integration of creative arts into anatomy education remains limited. The Synthetic Anatomy module was designed to bridge anatomy teaching with creative design for bioscience and biomedical engineering students. This study evaluates the module's educational impact

Targeting Amastigote and Trypomastigote Phases: Multi‐Epitope Vaccine Strategy Against Trypanosoma cruzi

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Effective vaccines against Trypanosoma cruzi, the causative agent of Chagas disease, are urgently needed. Here, we report the design and in silico validation of a novel multiepitope vaccine construct targeting the key surface proteins ASP‐2 and gp82. Using a comprehensive immunoinformatics pipeline, we identified and selected 38 potent T‐cell (
