Long-term memory facilitates spontaneous memory usage through multiple pathways.

Memories scaffold ongoing cognition and behavior. Surprisingly, when given the "sensorimnemonic" choice between using working memory (WM) and sampling sensory information from the environment, reliance on WM is much lower than expected. Here, we ask how the availability of long-term memory (LTM), alongside WM, changes how participants spontaneously sample sensory information in service of memory encoding, rely on their memory, and coordinate the two.

Effect of Lorazepam in Reducing Psychological Distress and Anticipatory Nausea and Vomiting in Patients Undergoing Chemotherapy.

Objectives: To evaluate the efficacy and safety of lorazepam in reducing psychological distress and chemotherapy-induced nausea and vomiting.

Methodology: It was a prospective interventional study with seventy patients for a period of 1 year. In which, patients' anxiety, distress and status of nausea, and vomiting were assessed in the first four chemotherapy cycles before drug intervention.

Aromatase and neuroinflammation in rat focal brain ischemia.

Accumulating evidence suggests that expression of aromatase, the enzyme responsible for the conversion of androgens to estrogens, is transiently upregulated in rat stroke models. It was further suggested that increased aromatase expression is linked to neuroinflammation and that it is neuroprotective in females. Our goal was to investigate aromatase upregulation in male rats subjected to experimental stroke in relationship to neuroinflammation, infarct and response to treatment with different putative neuroprotective agents.
