Aggressive interactions between members of a social group represent an important source of social stress with all its negative follow-ups. We used the ponerine ant Harpegnathos saltator to study the effects of frequent aggressive interactions on the resistance to different stressors. In these ants, removal or death of reproducing animals results in a period of social instability within the colony that is characterized by frequent ritualized aggressive interactions leading to the establishment of a new dominance structure. Animals are more susceptible to infections during this period, whereas their resistance against other stressors remained unchanged. This is associated with a shift from glutathione-S-transferase activities towards glutathione peroxidase activities, which increases the antioxidative capacity at the expense of their immune competence.

Background: A recent study revealed the oncogenic role of box C/D small nucleolar RNA 52 (SNORD52) in hepatocellular carcinoma (HCC) by facilitating the aggressive phenotypes of hepatoma cells. However, the potential role of exosomal SNORD52 in macrophage polarization during HCC progression remains poorly understood.
Methods: Exosomes were isolated from hepatoma cells.

Objective: This study investigated the clinical significance of mutations in patients with distant metastatic follicular cell-derived thyroid cancer (FDTC).
Methods: This study included 310 Chinese patients with distant metastatic FDTC. We analyzed the interactions between mutations and other gene alterations and compared the clinicopathological characteristics of patients with pathogenic (P) or likely pathogenic (LP) mutations (n=9), other gene alterations (n=253), and no gene alterations (n=37).

Objectives: The global prevalence of Hashimoto's thyroiditis (HT) and differentiated thyroid cancer (DTC), particularly papillary thyroid cancer (PTC), is increasing. However, studies assessing correlations between these diseases have yielded inconsistent findings. Furthermore, patients diagnosed with HT show a higher prevalence of indeterminate cytology than those without HT.
