Giant cell arteritis (GCA) is a large vessel vasculitis with cranial and extracranial vessel involvement. Clinicians suspect GCA when a patient exhibits symptoms or exam findings of temporal headache with sudden vision loss, jaw or tongue claudication, scalp tenderness, abnormal temporal artery exam, and diagnostic findings, including elevated inflammatory markers. We present a case, which highlights that, despite established diagnostic measures, challenges persist.

Here we demonstrate highly efficient remote chirality transfer where chirality is imposed on an otherwise achiral hybrid metal halide semiconductor by a proximal chiral molecule that is not interspersed as part of the structure yet leads to large circular dichroism dissymmetry factors (g) of up to 10. Density functional theory calculations reveal that the transfer of stereochemical information from the chiral proximal molecule to the inorganic framework is mediated by selective interaction with divalent metal cations.

However, there remains limited scientific study of the therapeutic potential or effectiveness of ethnobotanical applications. Increases in the incidence of cancer and emerging infectious diseases demonstrate a growing need for advances in the development of therapeutic options.

Methods: A 5-year, multicentre retrospective observational study was conducted across six public hospitals (metropolitan and regional) using data from electronic medical records. Patient presentations were identified using LBP diagnostic codes and key data extracted (patient demographics, clinical activity, discharge destination).
Botulinum neurotoxin A (BoNT/A) is a highly potent proteolytic toxin specific for neurons with numerous clinical and cosmetic uses. After uptake at the synapse, the protein is proposed to translocate from synaptic vesicles to the cytosol through a self-formed channel. Surprisingly, we found that after intoxication proteolysis of a fluorescent reporter occurs in the neuron soma first and then centrifugally in neurites.
