Article Abstract

Background/aim: The porous glass membrane pumping emulsification device enhances local therapeutic effects of transarterial chemoembolization for hepatocellular carcinoma (HCC); however, limited clinical outcomes have been reported. This study aimed to investigate the efficacy and safety of transarterial chemoembolization using the glass membrane pumping emulsification device for HCC.

Patients And Methods: Between 2019 and 2023, 58 patients (median age=73 years) with unresectable HCC underwent 73 transarterial chemoembolizations using the glass membrane pumping emulsification device at the Nagoya University Hospital. Treatment effects were assessed using contrast-enhanced computed tomography 1-3 months after therapy and every 2-3 months thereafter.

Results: The median size of treated tumors was 25.5 mm (45 solitary nodules). The median dosage of ethiodized oil mixed with the epirubicin solution was 3 ml. Complete and partial response were observed in 73% and 11% of patients, respectively. Local control rates at 6 and 12 months were 82.8% and 59.8%, respectively. The median time to recurrence after treatment was 581 days. No major treatment-related complications occurred. The number of tumors and therapeutic effects of the initial transarterial chemoembolization were significantly associated with better local control.

Conclusion: The glass membrane pumping emulsification device facilitated the accumulation of more concentrated ethiodized oil within the tumor and effective local control.

Optimization and application of pretreatment for the analysis of typical per- and polyfluoroalkyl substances (PFAAs) in drinking water: a systematic evaluation of filter membranes and SPE Sorbents.

The accurate detection of trace perfluoroalkyl acids (PFAAs) in drinking water remains challenging due to nonspecific adsorption losses during pretreatment. This study systematically evaluated the adsorption behaviors of 11 PFAAs across five filtration membranes and four solid-phase extraction (SPE) sorbents to establish an optimized analytical protocol. Results demonstrated that glass fiber (GL) filters minimized PFAAs retention (94.

Optimization of the measurement method for airborne endotoxins in workplace atmospheres: experiments using laboratory-generated bioaerosols.

Endotoxins are components of the outer membrane of bacteria that can become airborne during aerosol-generating work activities and cause adverse effects on workers' health. Filtration is the sampling method recommended by the EN 14031 standard for endotoxin measurements in workplace atmospheres. However, there are still differences in terms of practice regarding certain parameters of the measurement method.

Background: Reconstruction of head and neck mucosal defects presents unique challenges due to the anatomical complexity and functional demands of the region. Artificial biomaterials such as collagen and polyglycolic acid (PGA) sheets have gained clinical traction owing to their ease of use and reduced surgical burden. However, limitations such as local inflammation, degradation-related complications, and mechanical instability-particularly in highly mobile areas like the tongue-continue to hinder their broader application.

Corynebacterium amycolatum: an underestimated pathogen in early-onset neonatal sepsis-a case report.

BMC Infect Dis

September 2025

Department of Laboratory Medicine, West China Second University Hospital, Sichuan University, No.20, Section 3, Renmin South Road, Chengdu, Sichuan, 610041, P.R. China.

Background: Early-onset neonatal sepsis (EOS) is a critical condition primarily caused by maternal-fetal transmission of bacterial pathogens during delivery, with Escherichia coli and Group B Streptococcus being the most prevalent. However, neonatal sepsis can also involve other rare bacteria, including Corynebacterium amycolatum, which was first described in 1988 and is widely recognized as an emerging pathogen in infectious diseases.

Case Presentation: A male infant was admitted to the neonatal intensive care unit (NICU) due to premature birth and tachypnea.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a severe complication in patients undergoing long-term bisphosphonate therapy, while our knowledge on the pathogenesis of BRONJ is far from sufficient. Gamma delta (γδ) T cells predominantly distribute in mucosal tissues and play an important role in both immune modulation and bone metabolism; however, the mechanism of γδ T cells in the pathogenesis of BRONJ has not been elucidated. Here, we induced BRONJ-like lesions in wild-type (WT) and T-cell receptor delta-deficient (TCRδ) mice via intraperitoneal zoledronate injection.
