Real-World Utilization Patterns of Oral Corticosteroids During Pregnancy: A Nationwide Population-Based Study in Korea.

Oral corticosteroids (OCS) are frequently used during pregnancy, but patterns of their usage and indications are understudied. We described OCS utilization among pregnant women in South Korea using the Health Insurance Review and Assessment database, 2010-2021. Among 4,574,294 pregnancies, 6.

TNF α mediated IL-6 secretion is regulated by JAK/STAT pathway but not by MEK phosphorylation and AKT phosphorylation in U266 multiple myeloma cells.

IL-6 and TNF α were significantly increased in the bone marrow aspirate samples of patients with active multiple myeloma (MM) compared to those of normal controls. Furthermore, MM patients with advanced aggressive disease had significantly higher levels of IL-6 and TNF α than those with MM in plateau phase. TNF α increased interleukin-6 (IL-6) production from MM cells.

PKCδ promotes etoposide-induced cell death by phosphorylating Hsp27 in HeLa cells.

We investigated the regulation of Hsp27 phosphorylation by protein kinase C δ (PKCδ) during etoposide-induced apoptosis. The phosphorylation of Hsp27 at Ser78 was temporally correlated with the proteolytic activation of PKCδ during apoptosis. Hsp27 phosphorylation was dependent on the activity of PKCδ since treatment with rottlerin, a chemical inhibitor of PKCδ, or overexpression of a PKCδ dominant negative mutant abolished the phosphorylation.

A technique for concurrent procedure of mastoid obliteration and meatoplasty after canal wall down mastoidectomy.

Objective: To present a simple technique for concurrent procedure of mastoid obliteration and meatoplasty after canal wall down mastoidectomy, and to assess the efficacy and the surgical results of this technique.

Methods: Retrospective clinical study of a consecutive series of procedures from 2004 to 2008. One hundred thirteen patients undergone canal wall down mastoidectomy with tympanoplasty and concurrent procedure of mastoid obliteration and meatoplasty that uses an anteriorly based musculoperiosteal flap and a horizontal skin incision on the concha were included.

Pattern of cervical lymph node metastasis in tonsil cancer: predictive factor analysis of contralateral and retropharyngeal lymph node metastasis.

The purpose of this study was to determine the pattern of cervical lymph node metastasis in tonsil cancer including the retropharyngeal (RPLN) nodal metastasis. Seventy-six tonsillar squamous cell carcinoma patients who underwent surgery-based treatment were retrospectively analyzed. Most patients had advanced stage (stages III and IV: 81.

Caspase-3-dependent protein kinase C delta activity is required for the progression of Ginsenoside-Rh2-induced apoptosis in SK-HEP-1 cells.

Ginsenoside-Rh2 (G-Rh2) has been shown to induce apoptosis in a variety of cell types. In this study, we show that G-Rh2-induced apoptosis is accompanied by the mitochondrial release of cytochrome c and activation of caspase-3 in the human hepatoma cell line, SK-HEP-1. Furthermore, protein kinase C delta (PKCdelta) activity was markedly up-regulated in a lipid activator-independent manner with kinetics similar to those of PKCdelta and PARP cleavages during the apoptotic progression.
