This publication describes monodentate phosphine and oxazoline ligands attached to an amino acid ester and the application of their supramolecularly assembled rhodium(I) or iridium(I) complexes in asymmetric catalysis. The major feature of these complexes is the transmission of chirality from distant hydrogen bonded amino acids to the prochiral catalytic metal center ("backdoor induction"). The generated homoleptic and heteroleptic rhodium(I) or iridium(I) precatalysts were studied by NMR, UV-VIS and CD spectroscopy as well as X-ray single crystal diffraction.

- This review summarizes various chemical methods to transform renewable resources into benzenoid aromatics, considering materials like lignocellulose, carbohydrates, fats, and fermentation products.
- Two main approaches are highlighted: catalytic fast pyrolysis, which operates at high temperatures and produces biochar, gases, and aromatic oils, and a multi-step conversion process using platform chemicals derived from lignocellulose or sugars.
- Significant research has centered on furan compounds, with successful applications leading to the construction of large-scale plants for the conversion of lignocellulose to xylene, including one that has started operations in 2023.
Article Synopsis
- Parkinson's Disease (PD) affects neural activity primarily in the basal ganglia and cerebral cortex, and Deep Brain Stimulation (DBS) of the subthalamic nucleus is a key treatment when patients have motor complications from levodopa.
- Research shows that STN-DBS helps improve the brain's ability to transmit information, particularly in predicting limb movements, even if visible EEG patterns don't differ significantly with or without therapy.
- The study examines how different synaptic parameters and excitability levels in cortical networks contribute to enhanced information processing under STN-DBS, suggesting ways to optimize the treatment based on cortical activity measurement.
Background: This study evaluates whether there are ethnic differences in time to surgery in women with early-stage (1-3a) breast cancer in four NZ urban regions between 2000 and 2020 pre- and post- Faster Cancer Treatment (FCT) implementation, which was introduced to address inequities in cancer outcomes.
Methods: This retrospective analysis used (Breast Cancer Foundation National Register), a prospectively maintained database of breast cancers from 2000 to 2020. Women with stage 3b, 3c, metastatic or bilateral cancers were excluded.
