Cleopatra VII (69-30 BC), the last Ptolemaic ruler of Egypt, is probably best known for her love affairs with Julius Caesar (100-44 BC) and Marcus Antonius (83-30 BC). Rightly or wrongly she became the epitome of shrewd seduction, leading brave Roman commanders on a path to debauchery and destruction. Among the seductive strategies attributed to her is the ingestion of small amounts of turpentine [the resin of the terebinth tree ( Pistacia terebinthus )] or of derived oil ( Oleum terebinthinae ) with the purpose of conferring to her urine a more pleasant scent reminding of violets...

Levetiracetam (LEV) is an anti-epileptic drug with demonstrated efficacy against generalized seizures. Recent studies have found that LEV affects the release of neurotransmitters by binding to synaptic vesicle protein 2A (SV2A). However, the details of LEV regulation of synaptic transmission remain poorly understood. Here, we used the whole-cell patch-clamp technique to further characterize the effects of LEV on synaptic transmission at a large mammalian central synapse, the calyx of Held. Our results showed that two common forms of vesicle endocytosis, including slow and rapid endocytosis, were dramatically inhibited when slices were incubated in 100 μM LEV for 1 h, however, the action potential (AP), calcium influx and exocytosis were not affected...

Chemotherapy is among the standard treatments for esophageal cancer. The docetaxel, 5-fluorouracil, and cisplatin (DCF) protocol yields a better response rate than 5-fluorouracil plus cisplatin. However, the incidence of side effects, such as febrile neutropenia and hematologic toxicity, is also significantly high with the DCF protocol. The granulocyte colony-stimulating factor and pegfilgrastim are prophylactically administered to prevent febrile neutropenia. This retrospective study evaluated the efficacy and safety of pegfilgrastim in patients receiving DCF therapy...
