Targeted Delivery of Chlorin e6 via Redox Sensitive Diselenide-Containing Micelles for Improved Photodynamic Therapy in Cluster of Differentiation 44-Overexpressing Breast Cancer

Targeted Delivery of Chlorin e6 via Redox Sensitive Diselenide-Containing Micelles for Improved Photodynamic Therapy in Cluster of Differentiation 44-Overexpressing Breast Cancer Chan Feng1, Donglei Zhu1, Lv Chen1, Yonglin Lu1, Jie Liu1, Na Yoon Kim2, Shujing Liang1, Xia Zhang1, Yun Lin1, Yabin Ma3* and Chunyan Dong1* 1Cancer Center, Shanghai East Hospital, Tongji University, Shanghai, China 2Department of Chemical Engineering, Northeastern University, Boston, MA, United States 3Pharmacy Department, Shanghai East Hospital, Tongji University, Shanghai, China The off-target activation of photosensitizers is one of the most well-known obstacles to effective photodynamic therapy (PDT). The selected activation of photosensitizers in cancer cells is highly desired to overcome this problem. We developed a strategy that enabled diselenide bonds to link hyaluronic acid (HA) and photosensitizer chlorin e6 (Ce6) to assemble the micelles (HA-sese-Ce6 NPs) that can target cancer and achieve a redox responsive release of drugs to enhance the PDT efficiency in breast cancer. The HA was used to form a hydrophilic shell that can target cluster of differentiation 44 (CD44) on the cancer cells. The selenium-containing core is easily dissembled in a redox environment to release Ce6. The triggered release of Ce6 in a redox condition and the positive feedback release by activated Ce6 were observed in vitro. In cytotoxicity assays and in vitro cellular uptake assays, the increased P...

Authors: Fiore M, Di Franco S, Alfieri A, Passavanti MB, Pace C, Kelly M, Damiani G, Leone S Abstract INTRODUCTION: Spontaneous bacterial peritonitis (SBP) is a main infectious complication in end-stage liver disease (ESLD) patients. The increasing trend of bacterial resistance in ESLD patients with SBP has been associated with low treatment efficacy of traditional therapy. Cephalosporin use has been restricted to community-acquired infections and in areas/health care settings with low rates of multidrug-resistant (MDR) bacteria. To date, several changes are necessary with regard to empiric therapy recommendations ...

This study aimed to assess survival after TARE and to identify potential prognostic factors in this patient population. METHODS: Patients with unresectable and chemorefractory CRCLM treated with TARE at our institution between February 2006 and September 2015 were included in the study. Survival rate, hepatic tumor response, and potential prognostic factors were analyzed. RESULTS: In the 43 study patients, the mean follow-up was 15.0 ± 14.2 months, with a median survival of 13.0 months and 1-, 2-, 3-, 4-, and 5-year survival rates of 52.1%, 24.9%, 21.4%, 21.4%, and 7.1%, respectively. The mean activity of yt...

Authors: Coenen S, Weyts E, Geens P, Vermeire S, Ferrante M, Vanhaecht K, Van Assche G Abstract OBJECTIVES: Patient reported outcomes are widely used in today's clinical practice. The Short Health Scale has been proven to be an easy-to-use and reliable measure to evaluate quality of life in patients with inflammatory bowel disease. We aimed to validate this Short Health Scale in Dutch speaking patients. METHODS: A total of 157 Crohn's disease and ulcerative colitis patients (46% male, median age 39 years) completed the Short Health Scale on a tablet during the outpatient clinic. Validity was assessed by co...

CONCLUSIONS: There was an inverse correlation between temporal changes in the relative abundance of F. prausnitzii, but not overall butyrate producing capacity, and changes in inflammatory activity in ileal Crohn's disease. These findings indicate that F. prausnitzii may play a role in gut homeostasis, even though causality is still to be demonstrated. PMID: 31104514 [PubMed - as supplied by publisher]
