Transovarial Transmission of Heartland Virus by Invasive Asian Longhorned Ticks under Laboratory Conditions.

We demonstrated experimental acquisition and transmission of Heartland bandavirus by Haemaphysalis longicornis ticks. Virus was detected in tick salivary gland and midgut tissues. A total of 80% of mice exposed to 1 infected tick seroconverted, suggesting horizontal transmission.

Epidermal growth factor receptor-activating mutation(E746_T751>VP) in pancreatic ductal adenocarcinoma responds to erlotinib, followed by epidermal growth factor receptor resistance-mediating mutation (A647T): A case report and literature review.

Despite recent advances in treatment with multidrug chemotherapy regimens, outcomes of patients with advanced pancreatic ductal adenocarcinoma (PDAC) remain very poor. Treatment with targeted therapies has shown marginal benefits due to intrinsic or acquired resistance. Actionable mutations, while detected infrequently in patients with PDAC, are becoming increasingly used in personalized medicine.
