However, it has also been reported that PPMV-1 can infect chickens naturally and experimentally, thus posing a potential threat to the poultry industry. This study investigated a lethal outbreak of paramyxovirus infection that occurred among 16 oriental turtle doves (Streptopelia orientalis) in a walk-in aviary at a zoo from March to April 2021.

Inductive line tunneling FET using epitaxial tunnel layer with Ge-source and charge enhancement insulation.

In this paper, we propose an inductive line tunneling FET using Epitaxial Tunnel Layer with Ge-Source and Charge Enhancement Insulation (CEI ETL GS-iTFET). The CEI ETL GS-iTFET allows full overlap between the gate and source regions, thereby enhancing the line tunneling. In addition, a germanium layer is introduced on the source side to form a heterojunction, effectively improving the device's conduction current.

Effects of selective cyclooxygenase-2 inhibitor robenacoxib on primary cells derived from feline injection-site sarcoma.

Feline injection-site sarcomas (FISSs) are highly invasive malignant mesenchymal neoplasms that arise from injection sites in cats. Although the tumorigenesis of FISSs is still uncertain, there is a consensus that FISS is associated with chronic inflammation caused by irritation of injection-related trauma and foreign chemical substances. Chronic inflammation can provide a proper microenvironment for tumour development, which has been known as one of the risk factors of tumorigenesis in many tumours.
