Granule cells of the cerebellum make up to 175,000 excitatory synapses on a single Purkinje cell, encoding the wide variety of information from the mossy fibre inputs into the cerebellar cortex. The granule cell axon is made of an ascending portion and a long parallel fibre extending at right angles, an architecture suggesting that synapses formed by the two segments of the axon could encode different information. There are controversial indications that ascending axon (AA) and parallel fibre (PF) synapse properties and modalities of plasticity are different.

Prices of anticancer medicines (including chemically synthesized medicines and biologics manufactured from living organisms) are a subject of concern, as they contribute to spending by health plans and patients. We describe prices and evaluate the impact of competition among 185 anticancer medicines, using IQVIA data from the period October 2014-February 2020. We calculated the price of each medicine, defined as volume-weighted wholesale costs net of prompt-pay discounts and gross of rebates, without and with inflation adjustment, and summarized them by patent status, formulation, and therapeutic class.

Current chemical platforms are often limited by their complexity, toxicity, and poor physical/chemical properties. Here, we report on the synthesis of a structurally versatile library of chemically tunable bisacylphosphane oxides (BAPOs), which harnesses the spatiotemporal precision of light delivery, thereby establishing a universal strategy for on-demand, precise cellular ablation and .
