Na-Complexed Dendritic Polyglycerols for Recovery of Frozen Cells and Their Network in Media.

In this study, a novel phenomenon is identified where precise control of topology and generation of polyglycerol induce the retention of Na ions in biological buffer systems, effectively inhibiting ice crystal growth during cryopreservation. Unlike linear and hyperbranched counterparts, densely-packed hydroxyl and ether groups in 4th-generation dendritic polyglycerol interact with the ions, activating the formation of hydrogen bonding at the ice interface. By inhibiting both intra- and extracellular ice growth and recrystallization, this biocompatible dendritic polyglycerol proves highly effective as a cryoprotectant; hence, achieving the cell recovery rates of ≈134-147%, relative to those of 10% dimethyl sulfoxide, which is a conventional cryoprotectant for human tongue squamous carcinoma (HSC-3) cell line and human umbilical vein endothelial (HUVEC) cells.

Cyanoacrylate Glue Ablation for Symptomatic Reflux in a Duplicated Femoral Vein: A Case Report.

The literature on minimally invasive techniques specifically targeting reflux in symptomatic femoral vein duplication (FVD) is limited. We present a rare case of symptomatic reflux in FVD, successfully treated with cyanoacrylate glue ablation under ultrasonographic guidance. Our findings suggest that the unique anatomy of FVD can be effectively addressed through percutaneous endovenous glue ablation, providing a technically safe and feasible alternative without open surgery.

Reproductive factors and risk of epithelial ovarian cancer: results from the Asia Cohort Consortium.

Background: There are scarce data on risk factors for epithelial ovarian cancer (EOC) in Asian populations. Our goal was to advance knowledge on reproductive -related risk factors for EOC in a large population of Asian women.

Methods: This study used pooled individual data from baseline questionnaires in 11 prospective cohorts (baseline years, 1958-2015) in the Asia Cohort Consortium.

Adherence to the Cancer Prevention Recommendations from World Cancer Research Fund/American Institute for Cancer Research After Cancer Diagnosis on Mortality in South Korea.

Background/objectives: The World Cancer Research Fund/American Institute for Cancer Research recommends following the recommendations for cancer prevention even after cancer diagnosis. To provide evidence on the potential benefits of adherence on improved survival, we investigated the effects of post-diagnostic adherence to the recommendations regarding diet, physical activity, and body weight on all-cause mortality among Korean cancer survivors.

Methods: Among the total number of cancer survivors ( = 173,195) recruited from 2004 to 2013 for the Health Examinees study, 5485 were selected for the analyses and classified by tertiles according to the adherence score.
