Trefoil factor 3 (TFF3), a regulatory protein composed of 59 amino acids, has been suggested to be involved in pathogen- esis, proliferation, invasion, migration and apoptosis in multiple malignant tumors. However, the roles of TFF3 concerning the viability, migration and invasion in papillary thyroid carcinoma cells have not yet been studied. This study aimed to investigate the effect of TFF3 knockdown on a thyroid papillary carcinoma TPC-1 cell line both in vitro and in vivo. In the present study, lentivirus-mediated short hairpin RNA (shRNA) targeting TFF3 plasmids were first constructed and stable TPC-1 cells were obtained while their TFF3 gene was silenced with either shTFF3-TPC-1, or a scrambled shRNA control...

Pistachio, one of the important tree nuts, is cultivated in arid and semi-arid regions where salinity is the most common abiotic stress encountered by this tree. However, the mechanisms underlying salinity tolerance in this plant are not well understood. In the present study, five 1-year-old pistachio rootstocks (namely Akbari, Badami, Ghazvini, Kale-Ghouchi, and UCB-1) were treated with four saline water regimes (control, 8, 12, and 16 dS m-1 ) for 100 days. At high salinity level, all rootstocks showed decreased relative water content (RWC), total chlorophyll content (TCHC), and carotenoids in the leaf, while ascorbic acid (AsA) and total soluble proteins (TSP) were reduced in both leaf and root organs...

BACKGROUND: Current periodontal disease taxonomies have limited utility for predicting disease progression and tooth loss; in fact, tooth loss itself can undermine precise person-level periodontal disease classifications. To overcome this limitation, the current group recently introduced a novel patient stratification system using latent class analyses of clinical parameters, including patterns of missing teeth. This investigation sought to determine the clinical utility of the Periodontal Profile Classes and Tooth Profile Classes (PPC/TPC) taxonomy for risk assessment, specifically for predicting periodontal disease progression and incident tooth loss...
