Morphological change and differential proteomics analysis of gill in under starvation.

is a dominant shellfish in the Yangtze estuary and its adjacent sea area. Food deprivation often occurs during their growth due to fluctuations in algal abundance caused by seasonal freshwater flushing and high-density aquaculture mode. To investigate the coping strategies of to starvation stress, electron microscopy and differential proteomic analysis were performed on the critical feeding organ gill of the mussels after 9 days of starvation.

Reflecting on the utility of standardized uptake values on F-FDG PET in nasopharyngeal carcinoma.

Background: To rethink the clinical significance of standardized uptake values (SUVs) of nasopharyngeal carcinoma (NPC) on F-fluorodeoxyglucose (F-FDG) positron-emission tomography (PET).

Methods: We retrospectively reviewed 369 NPC patients who underwent pretreatment F-FDG PET. The predictive value of the SUVmax of the primary tumor (SUVmax-t) and regional lymph nodes (SUVmax-n) was evaluated using probability density functions.

Selectively recommend F-FDG PET/CT for patients with de novo nasopharyngeal carcinoma in endemic areas.

Introduction: To identify the subset of patients with de novo nasopharyngeal carcinoma (NPC) for whom [F] fluorodeoxyglucose positron emission tomography and computed tomography (F-FDG PET/CT) should be recommended, and to determine whether PET/CT is a cost-effective decision for precise M staging in endemic areas.

Materials And Methods: Retrospective analysis of data of 4469 patients diagnosed with de novo NPC between January 2014 and December 2019. The detection rate of distant metastasis was compared between different groups.
