A Case of Advanced Lung Adenocarcinoma Harboring an Epidermal Growth Factor Receptor(EGFR) Exon 20 Insertion, D770_N771insSVD.

A 57-year-old female was diagnosed as having advanced lung adenocarcinoma. Combination chemotherapy using cisplatin plus pemetrexed was introduced. However, her disease progressed during the maintenance therapy with pemetrexed.

Effect of the expression of aquaporins 1 and 3 in mouse oocytes and compacted eight-cell embryos on the nucleation temperature for intracellular ice formation.

The occurrence of intracellular ice formation (IIF) is the most important factor determining whether cells survive a cryopreservation procedure. What is not clear is the mechanism or route by which an external ice crystal can traverse the plasma membrane and cause the heterogeneous nucleation of the supercooled solution within the cell. We have hypothesized that one route is through preexisting pores in aquaporin (AQP) proteins that span the plasma membranes of many cell types.
