Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

open access: yesThe Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Two-photon microscopy : sequential imaging studies in vivo [PDF]

open access: yes, 2011
Microscopists have always desired to look inside various organ tissues to study structure, function and dysfunction of their cellular constituents. In the past, this has frequently required tissue extraction and histological preparation to gain access ...

Effect of strain rate on the yielding mechanism of amorphous metal foam [PDF]

open access: yes, 2010
Stochastic amorphous Pd_(43)Ni_(10)Cu_(27)P_(20) foams were tested in quasistatic and dynamic loading. The strength/porosity relations show distinct slopes for the two loading conditions, suggesting a strain-rate-induced change in the foam yielding ...

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Managing the risk of iatrogenic transmission of Creutzfeldt-Jakob disease in the UK.

open access: yes, 2014
BACKGROUND: With the emergence of bovine spongiform encephalopathy (BSE) and variant Creutzfeldt-Jakob disease (CJD) in the UK, there is concern about iatrogenic transmission, and the approach to managing this risk is unique.

Hyperostosis frontalis interna: Observed patterns, prevalence, and dementia associations in older adults

open access: yesThe Anatomical Record, EarlyView.
Abstract Hyperostosis frontalis interna (HFI) is a frequently underrecognized condition characterized by overgrowth of the frontal endocranium, most commonly observed in post‐menopausal women. Although its etiology remains unclear, hormonal influences and a possible relationship with neurocognitive changes have been proposed.

Uso da hidrocortisona no tratamento e na prevenção da cefaléia pós-punção da dura-máter: relato de casos Uso de la hidrocortisona en el tratamiento y en la prevención de la cefalea después-punción de la dura-máter: relato de casos Hydrocortisone treatment and prevent post-dural puncture headache: case reports

open access: yesRevista Brasileira de Anestesiologia, 2005
JUSTIFICATIVA E OBJETIVOS: A cefaléia pós-punção da dura-máter é a complicação mais freqüente após a raquianestesia ou a sua perfuração acidental durante tentativa de bloqueio peridural.

Overcoming intranasal delivery barriers with ultrastable polyzwitterionic siRNA nanocages for enhanced glioblastoma therapy

open access: yesBMEMat, EarlyView.
A ROS‐responsive, zwitterionic nanocage enables stable, intranasal siRNA delivery to glioblastoma, promoting deep tumor penetration via non‐degradative pathways and trigeminal nerve transport. This platform achieves durable gene silencing and tumor suppression, offering a non‐invasive, storage‐stable strategy for treating glioma and other neurological ...

Spectral entropy variability of intraoperative electrocorticography predicts outcome after epilepsy surgery in people with focal cortical dysplasia

open access: yesEpilepsia, EarlyView.
Abstract Objective Epilepsy surgery in people with focal cortical dysplasia (FCD) requires accurate removal of all epileptogenic tissue, and outcome is difficult to predict. We explored whether spectral entropy, a fast computable electroencephalographic (EEG) feature, could estimate epileptic activity in intraoperative electrocorticography (ioECoG) and

Dual role of spreading depolarization in an epileptic focus

open access: yesEpilepsia, EarlyView.
Abstract Objective Spreading depolarizations (SDs) are often associated with epileptic discharges. Although SDs are traditionally thought to contribute to postictal depression and termination of epileptic discharges, seizures may also occur during SDs or may even follow SDs, suggesting that interactions between SD and seizures are more complex.
