An iron-carbon coupled biofilm airlift internal circulation sequencing batch reactor (IC-SBR) was constructed to treat low-carbon source wastewater. Single-factor experiments were used to determine the optimal operating conditions for the IC-SBR, with a hydraulic retention time (HRT) of 10 h, a dissolved oxygen (DO) concentration of 3 mg/L, a C/N ratio of 3, and an influent NH-N concentration of 50 mg/L, with average removal efficiencies of total nitrogen (TN) and total organic carbon (TOC) of 78.06% and 97.

The effects of antibiotics, such as tetracycline, sulfamethoxazole, and ciprofloxacin, on functional microorganisms are of significant concern in wastewater treatment. This study observed that Acinetobacter indicus CZH-5 has a limited capacity to remove nitrogen and phosphorus using antibiotics (5 mg/L) as the sole carbon source. When sodium acetate was supplied (carbon/nitrogen ratio = 7), the average removal efficiencies of ammonia-N, total nitrogen, and orthophosphate-P increased to 52.

This study provides for the first time a systematic understanding of Acinetobacter indicus CZH-5 performance, metabolic pathway and genomic characteristics for aerobic nitrogen (N) and phosphorus (P) removal. Acinetobacter indicus CZH-5 showed promising performance in heterotrophic nitrification aerobic denitrification and aerobic phosphorus removal. Under optimal conditions, the maximum ammonia-N, total nitrogen and orthophosphate-P removal efficiencies were 90.

Recovering finite and non-substitutable phosphorus from liquid waste streams through bio-mediated techniques has attracted increasing interest, but current approaches are incredibly dependent on ammonium. Herein, a process to recover phosphorus from wastewater under multiple nitrogen species conditions was developed. This study compared the effects of nitrogen species on the recovery of phosphorus resources by a bacterial consortium.

In this study, A Acinetobacter pittii sp. was isolated with high efficiency for heterotrophic nitrification and aerobic denitrification (HN-AD). The boundary conditions for total nitrogen (TN) removal were as follows: C/N ratios 8-14, temperature 25-35 °C, initial pH 7-9, and shaker speed 100-120 rpm.

Diabetic kidney disease (DKD) is one of the most serious complications of diabetic patients. Advanced glycation end products (AGEs) induce epithelial-mesenchymal transformation (EMT) of renal tubular epithelial cells (HK-2), resulting in renal tubulointerstitial fibrosis. However, the underlying epigenetic mechanisms remain to be further investigated.

The effect of tetracycline (TC) on nitrogen removal in wastewater treatment plants has become a new problem. This study investigated the effects of TC on nitrogen removal using a Moving Bed Biofilm Reactor system. The results showed that there was no significant effect on nitrogen removal performance when the concentration of TC was 5 mg/L, and that the total nitrogen (TN) removal efficiency could reach 75-77%.

Little information about the selective stress of various antibiotics and how they influence different stages of aerobic nitrogen removal is available. A long-term aerobic nitrogen removal-moving bed biofilm reactor was established by the inoculation of Achromobacter sp. JL9, capable of heterotrophic nitrification and aerobic denitrification, and aerobic activated sludge.

Background: Pyroptosis mediated by NLRP3 inflammasome plays a critical role in the pathogenesis of cerebral ischemia-reperfusion (I/R) injury. Mounting evidences have verified the efficacy of exosomes by relieving the inflammatory response during cerebral I/R injury, but the specific mechanism has not been well elucidated. This study aimed to clarify whether the neuroprotective effects of bone marrow mesenchymal stem cell-derived exosomes (BMSC-Exos) are associated with the attenuation of NLPR3-mediated neuron pyroptosis by modulating microglial polarization.

: Cerebral ischemia-reperfusion (I/R) injury can lead to severe dysfunction, and its treatment is difficult. It is reported that nucleotide-binding domain and leucine-rich repeat family protein 3 (NLRP3) inflammasome-mediated cell pyroptosis is an important part of cerebral I/R injury and the activation of autophagy can inhibit pyroptosis in some tissue injury. Our previous study found that the protective effects of bone marrow mesenchymal stem cells (BMSCs) in cerebral I/R injury may be associated with the regulation of autophagy.

In this work, we proposed a carry-on nitric-oxide (NO) luggage strategy for enhanced chemotherapeutic efficacy. A stimuli-responsive NO-releasing polypeptide was prepared as the building block to assemble into a micelle as a chemodrug-carrier. The micelle was anchored with cRGD peptide with the aim of targeting to tumors' neoangiogenesis.

Oncogenic microRNAs are essential components in regulating the gene expression of cancer cells. Especially miR21, which is a major player involved of tumor initiation, progression, invasion and metastasis in several cancers. The delivery of anti-miR21 sequences has significant potential for cancer treatment.

Reperfusion injury exists as the major obstacle to full recovery of neuron functions after ischemic stroke onset and clinical thrombolytic therapies. Complex cellular cascades including oxidative stress, neuroinflammation, and brain vascular impairment occur within neurovascular units, leading to microthrombus formation and ultimate neuron death. In this work, a multitarget micelle system is developed to simultaneously modulate various cell types involved in these events.

Anticancer therapies, which can induce cell death and elevate antitumor immune response in the meantime, are considered as effective treatments for many types of cancers. Immunogenic cell death (ICD) induced by chemodrugs is a promising and typical strategy to achieve cell cytotoxicity and immunological enhancement together. However, due to the low level of ICD induction and less tumor-targeting accumulation, application of traditional ICD inducers is limited.

Targeted delivery and accumulation of chemotherapeutics to tumor sites is in high demand and extremely challenging for anticancer therapy. Studies show that albumin is actively recruited into tumor tissue overexpressing albumin-binding proteins including secreted protein acidic and rich in cysteine (SPARC) and gp60. Herein, a novel redox-responsive paclitaxel-loaded micelle system with the modification of ABD035, which specifically and strongly binds to albumin, is designed to combine the strengths of albumin and micelles together for antitumor drug biomimetic delivery.

In this paper, BiS nanospheres with size of 212nm were prepared by a simple hydrothermal process. The selectively enhanced antibacterial effects of BiS nanospheres with three classes of ineffective antibiotics, β-lactam (cefuroxime, CXM; cefotaxime, CTX and piperacillin, PIP), quinolone (ciprofloxacin, CIP) and aminoglycoside (gentamicin, GEN) against clinical isolated methicillin-resistant Staphylococcus aureus (MRSA) were investigated for the first time. GEN shows significantly synergistic growth inhibition against MRSA when combined with BiS nanospheres, while CXM, CTX, PIP and CIP do not.

Nano Ag/ZnO hybrid material has been considered to be a promising nanocomposites for biomedical application because it has enhanced antibacterial activity and low cytotoxicity. Here a sponge-like nano Ag/ZnO-loaded chitosan composite dressing was first synthesized via preparing a chitosan sponge by lyophilization process, followed by the incorporation of Ag/ZnO nanocomposites into chitosan sponge. The porosity, swelling, blood clotting and in vitro antibacterial activity against drug-sensitive and drug-resistant pathogenic bacteria were evaluated.

Background: Serum preβ1-high density lipoprotein (preβ1-HDL) was defined by two-dimensional non-denaturing linear gel electrophoresis and apolipoprotein A-I immuno-blotting. Serum preβ1-HDL seems to play an important role in reverse cholesterol transport, a well-known anti-atherosclerosis process. However, there are still debatable questions for its quantification and coronary artery disease (CAD) relevance.
