Article Synopsis
- Mass spectrometry imaging (MSI) is a technique used to visualize lipid distribution in tissues, allowing for rapid measurement without the need for sample pretreatment.
- This study focuses on the impact of different solvent properties on lipid imaging in mouse brain tissue using tapping-mode scanning probe electrospray ionization (t-SPESI) with very small solvent volumes.
- The research found that a mixture of non-protic (like dimethylformamide) and protic (like methanol) solvents improves lipid ion signal intensity and spatial resolution, highlighting the critical role of solvent choice for effective MSI.

Field-effect transistors using correlated electron materials with an electronic phase transition pave a new avenue to realize steep slope switching, to overcome device size limitations and to investigate fundamental science. Here, we present a new finding in gate-bias-induced electronic transport switching in a correlated electron material, i.e.

A novel SAAF was isolated from the title ascidian. The structure was elucidated using the entire sample of 4 nmol, suggesting that the position of the OH group confers genus-specificity to sperm chemotaxis in ascidians. This study not only provides insight into the chemical tactics in sperm chemotaxis but demonstrates that the innovative techniques allow structure determination of natural products in trace amounts.

Various stresses cause the accumulation of unfolded proteins in the endoplasmic reticulum (ER). To manage the state, cells have the unfolded protein responses (UPR). If the UPR is unsuccessful, ER-mediated apoptosis occurs.
