Basal cell adenoma is an uncommon benign salivary gland neoplasm, presenting isomorphic basaloid cells with a prominent basal cell layer. Basal cell adenoma arising from the nasal septum is exceptionally rare. Reports on positron emission tomography with 2-deoxy-2-fluorine-18-fluoro-D-glucose (18FDG-PET) imaging for basal cell adenoma are limited. Here, we present the case of a 49-year-old man who had the symptoms of intermittent repeated bleeding from the left nose for half a year. 18FDG-PET scanning showed increased accumulation of 18FDG with its characteristic benign pathology has a potential to malignancy. After removal of the mass, the patient became symptom free. Pathology showed basal cell adenoma. The evidence of active and growing cells was present in the specimen.

Rutin is a widely known plant secondary metabolite that exhibits multiple physiological functions. The present study focused on screening for synergistic antibacterial combinations containing rutin, and further explored the mechanisms behind this synergy. In vitro antibacterial test results of rutin showed that the ranges of minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) are 0.

This study examined the response to cisplatin in BxPC-3, Mia-Paca-2, PANC-1, and YAPC pancreatic cancer lines with different genotypic and phenotypic characteristics, and the mechanisms associated with their resistance. BxPC-3 and MIA-PaCa-2 cell lines were the most sensitive to cisplatin, while YAPC and PANC-1 were more resistant. Consistently, in cisplatin-treated BxPC-3 cells, the cleavage patterns of pro-caspase-9, -7, -3, and PARP-1 demonstrated that they were more sensitive than YAPC cells.

We aim to investigate whether chemical inhibition of NRF2 transcriptional activity (TA) influences distal colon contractions, particularly in an age-dependent manner in females, and whether it impacts oestrogen receptor signalling in female mice. This study was performed on 3 and 6-month-old female mice treated with ML385 (30 mg/kg) or a vehicle for 7 days (i.p.
