The distinction between choriocarcinoma and residual trophoblastic cell proliferation from a complete hydatidiform mole/invasive mole (CHM/IM) without villi is challenging on curettage materials. We investigated whether SALL4 immunostaining could help differentiate various gestational trophoblastic diseases. Placental site nodules (PSN; n=10), atypical PSN (APSN; n=8), placental site trophoblastic tumors (PSTT; n=9), epithelioid trophoblastic tumors (ETT; n=5), gestational choriocarcinomas (n=31), partial hydatidiform moles (PHM; n=13), CHM/IM (n=47), and nonmolar products of conception (POC) (n=26) were included.

Apolipoprotein C1 (APOC1) plays a significant role in the proliferation and metastasis of various malignant tumors; however, its role in DLBCL-particularly its effects on angiogenesis-remains largely unexplored. This study investigates the correlation between APOC1 expression and patient prognosis in DLBCL.

Background: Chimeric antigen receptor T (CAR-T) cell therapy is more effective in relapsed or refractory diffuse large B cell lymphoma (DLBCL) than other therapies, but a high proportion of patients relapse after CAR-T cell therapy owing to antigen escape, limited persistence of CAR-T cells, and immunosuppression in the tumor microenvironment. CAR-T cell exhaustion is a major cause of relapse. Epigenetic modifications can regulate T cell activation, maturation and depletion; they can be applied to reduce T cell depletion, improve infiltration, and promote memory phenotype formation to reduce relapse after CAR-T cell therapy.

Myoepithelioma-like tumor of the vulvar region (MELTVR) is a rare mesenchymal tumor that typically arises in the female vulva. Here, we report a case of a 48-year-old woman who presented with a 2-year history of subcutaneous mass in the vulvar region. As the mass rapidly increased in the last 2 months, personal slight swelling pain appeared.

Ascorbyl tetraisopalmitate (VC-IP) is a novel form of ascorbic acid characterized by reduced water solubility due to complete acylation with palmitate. This study investigated the potential cosmetic application of VC-IP when encapsulated in lyotropic liquid crystal nanoparticles (VC-IP LCNPs) by using a high-pressure homogenization (HPH) method. The particle size, zeta potential, and polydispersity index (PDI) of the obtained VC-IP LCNPs were determined as 158.
