Breast-Conserving Surgery with Immediate Partial Breast Reconstruction by Using Pedicled Thoracodorsal Artery Perforator Flap: A 7-Year Follow-Up of 50 Women.

Introduction: Thoracodorsal artery perforator (TDAP) flap has been used for more than 10 years in the immediate partial breast reconstruction (IPBR) of breast cancer, allowing many patients to maximize reserved autologous breast tissue who do not have indications for breast-conserving surgery (BCS). No large sample size survival data for this operation have been reported worldwide.

Methods: There are 212 primary breast cancer patients who were prepared to receive BCS with IPBR of pedicled TDAP flaps in our institution from June 2013 to December 2017.

Intensive treatment of triple negative breast cancer with residual positive axillary lymph node after neoadjuvant chemotherapy.

Background: Neoadjuvant chemotherapy (NAC) with anthracycline sequential paclitaxel is the standard regimen for triple negative breast cancer (TNBC), while TNBC with residual positive axillary lymph node after standard NAC indicates poor prognosis. There is no evidence that vinorelbine alone can be used as an adjuvant intensive therapy for such patients at present.

Methods: We recruited TNBC patients with clinical stage of T1-4/N1-3/M0, who received NAC with 8 cycles of anthracycline sequential paclitaxel and had residual tumor in axillary lymph node after surgery.

Role of polylactic acid microplastics during anaerobic co-digestion of cow manure and Chinese cabbage waste enhanced by nanobubble.

With the increasing use of plastic products globally, environmental pollution by plastic waste is becoming increasingly problematic. This study investigated the impacts of two types of polylactic acid microplastics, clear microplastics and aluminised film microplastics, on methane yield, microbial community, and volatile fatty acid accumulation during anaerobic co-digestion of cow manure and Chinese cabbage waste under different temperature conditions. The influence of the addition of air nanobubbles on microplastic degradation in the anaerobic digestion system we also examined.

To enhance the dewaterability of anaerobic digested sludge and to make full use of the biogas slurry. This study set up five sludge conditioning methods: polymeric ferric sulfate, polymeric aluminum chloride, cationic polyacrylamide, chitosan, and chitosan combined with rice husk powder. Their effects on the dewaterability of thermal hydrolysis-anaerobic digested sludge, bacterial community, and biogas slurry fertility were studied to find a non-toxic and non-risk dewatering technology for the environment and biogas slurry.

Comparison of Thermophilic-Mesophilic and Mesophilic-Thermophilic Two-Phase High-Solid Sludge Anaerobic Digestion at Different Inoculation Proportions: Digestion Performance and Microbial Diversity.

This study investigated the performance of thermophilic-mesophilic (T-M) and mesophilic-thermophilic (M-T) two-phase sludge anaerobic digestion at different inoculation proportions after a change in digestion temperature. After temperature change, the pH, total ammonia nitrogen (TAN), free ammonia nitrogen (FAN), solubility chemical oxygen demand (SCOD), and total alkalinity (TA) levels of two-phase digesters were between thermophilic control digesters and mesophilic control digesters. However, the volatile fatty acid (VFA) levels of two-phase digesters were higher than those of thermophilic or mesophilic control digesters.
