The Role of Lactate in Ischemic Stroke: As an Energy Source and Signaling Molecule.

Stroke is an acute cerebrovascular disease that causes brain tissue damage due to sudden blockage or rupture of blood vessels in the brain. According to the latest data from the Global Burden of Disease Study, the number of stroke patients worldwide is estimated to exceed 100 million, and more than 80% of patients suffer from stroke. Ischemic stroke is a type of stroke due to which two-thirds of the patients are disabled or even die, seriously affecting the patient's quality of life.

Combating cisplatin-resistant lung cancer using a coiled-coil peptides modified membrane fused drug delivery system.

Drug resistance to chemotherapy in treating cancers becomes an increasingly serious challenge, which leads to treatment failure and poor patient survival. Drug-resistant cancer cells normally reduce intracellular accumulation of drugs by controlling drug uptake and promoting drug efflux, which severely limits the efficacy of chemotherapy. To overcome this problem, a membrane fused drug delivery system (MF-DDS) was constructed to treat cisplatin (DDP)-resistant lung cancer (A549-DDP) by delivering DDP via membrane fusion using a complementary coiled-coil forming peptides (CPK/CPE).
