Endocytic recycling as cellular trafficking fate of simvastatin-loaded discoidal reconstituted high-density lipoprotein to coordinate cholesterol efflux and drug influx.

Reconstituted high-density lipoproteins (rHDLs) hold promise as nanocarriers for atherosclerosis-targeted delivery, with biofunctions typified by mediating cholesterol efflux. The paradox is how rHDL offloads the delivered drugs into atherosclerotic foam cells, while simultaneously transferring cholesterol out of cells. Herein, simvastatin-loaded discoidal rHDL (ST-d-rHDL), constructed based on established paradigms, was employed to investigate its basic trafficking mechanism in foam cells.

Postoperative adjuvant TACE-associated nomogram for predicting the prognosis of resectable Hepatocellular Carcinoma with portal vein Tumor Thrombus after Liver Resection.

To explore the effects of postoperative adjuvant transarterial chemoembolization (PA-TACE) on the prognosis of HCC patients with Portal Vein Tumor Thrombus (PVTT) undergoing resection, and to develop a PA-TACE-related nomogram for predicting survival individually. Two hundred and ninety-three consecutive HCC patients with PVTT under R0 hepatectomy were recruited. Forty-seven cases had recurrence within one month after surgery.

Mitophagy-lysosomal pathway is involved in silver nanoparticle-induced apoptosis in A549 cells.

With the increasing use of silver nanoparticles (AgNPs) in biological materials, the cytotoxicity caused by these particles has attracted much attention. However, the molecular mechanism underlying AgNP cytotoxicity remains unclear. In this study, we aimed to systematically investigate the toxicity induced by AgNP exposure to the lung adenocarcinoma A549 cell line at the subcellular and signaling pathway levels and elucidate the related molecular mechanism.

Flexible and disposable gold nanoparticles-N-doped carbon-modified electrochemical sensor for simultaneous detection of dopamine and uric acid.

Catalytic and electrocatalytic applications of supported metal nanoparticles are hindered due to an aggregation of metal nanoparticles and catalytic leaching under harsh operations. Hence, stable and leaching free catalysts with high surface area are extremely desirable but also challenging. Here we report a gold nanoparticles-hosted mesoporous nitrogen doped carbon matrix, which is prepared using bovine serum albumin (BSA) through calcination.

House Dust Mite Exposure Causes Increased Susceptibility of Nasal Epithelial Cells to Adenovirus Infection.

Adenovirus (AdV) infections in the respiratory tract may cause asthma exacerbation and allergic predisposition, and the house dust mite (HDM) may aggravate virus-induced asthma exacerbations. However, the underlying mechanisms of whether and how AdV affects asthmatic patients remains unclear. To address this question, we investigated nasal epithelial cells (NAEPCs) derived from a pediatric exacerbation study cohort for experimental analyses.

Efficient production of inulin and oligosaccharides using thermostable inulosucrase from Lactobacillus jensenii.

Investigation of Plasma Metabolic and Lipidomic Characteristics of a Chinese Cohort and a Pilot Study of Renal Cell Carcinoma Biomarker.

Plasma metabolomics and lipidomics have been commonly used for biomarker discovery. Studies in white and Japanese populations suggested that gender and age can affect circulating plasma metabolite profiles; however, the metabolomics characteristics in Chinese population has not been surveyed. In our study, we applied liquid chromatography-mass spectrometry-based approach to analyze Chinese plasma metabolome and lipidome in a cohort of 534 healthy adults (aging from 15 to 79).

Sugar alcohols derived from lactose: lactitol, galactitol, and sorbitol.

Lactose is a common natural disaccharide composed of galactose and glucose molecules. It is mainly found in the whey, the by-product of cheese and casein industries. As the supply of lactose far exceeds demand, a lot of lactose was discarded as the waste every year, which not only leads to resource waste, but also causes environmental pollution.

Microbial community and function evaluation in the start-up period of bioaugmented SBR fed with aniline wastewater.

An enhanced sequencing batch reactor (SBR) system was developed to treat synthetic wastewater rich in 600 mg/L aniline. The aniline degradation efficiency was almost 100%, and the total nitrogen (TN) removal rate was more than 50%. Metagenomics technology revealed the community structure, functional genes and metabolic mechanism during the start-up of the enhanced reactor.

High-Throughput Cloning and Characterization of Emerging Adenovirus Types 70, 73, 74, and 75.

Recently an increasing number of new adenovirus types associated with type-dependent pathogenicity have been identified. However, identification of these clinical isolates represents the very first step to characterize novel pathogens. For deeper analyses, these adenoviruses need to be further characterized in basic virology experiments or they could be applied in translational research.

Methods: Vascular smooth muscle cells (VSMCs) stimulated by oxidized low-density lipoprotein (ox-LDL) were served as a cellular model of AS.

Periosteal new bone formation in Klippel-Trénaunay syndrome: a case report.

Background: Klippel-Trénaunay syndrome (KTS) is a complex congenital vascular disorder, typically accompanied by port-wine stains, varicose veins, and limb hypertrophy. This paper reports a rare and unusual clinical condition of periosteal reaction in a pediatric case of KTS. Although periosteal new bone formation is not rare in children, as is KTS, their dual occurrence or the presentation of the former due to KTS has not been previously documented.

The effect of hepcidin in rats with renal ischemia/reperfusion injury.

Objective: This study sought to investigate the effectiveness of hepcidin in renal ischemia/reperfusion injury by using a rat model of renal IRI.

Methods: In our study, male Sprague-Dawley rats were divided into a hepcidin-treated group and a control group before establishing the animal models. According to the difference of the modelling methods (renal pedicle occlusion for 45 minutes or not) and renal reperfusion time, the rats were then respectively divided into four subgroups: sham, IRI 4 h, IRI 12 h, and IRI 24 h.

Constructing Rh-Rh modified TaO@TaON@TaN with special double n-n mutant heterojunctions for enhanced photocatalytic H-evolution.

A multiple core-shell heterostructure Rh-Rh modified TaO@TaON@TaN nanophotocatalyst was successfully constructed through nitriding Rh-doped TaO nanoparticles, which exhibited a much higher carrier separation efficiency about one order of magnitude higher than the TaO@TaN precursor, and thus an excellent visible light photocatalytic H-evolution activity (83.64 μmol g h), much superior to that of Rh anchored TaO@TaON (39.41 μmol g h), and improved stability due to the residual Rh-O/N in the TaN shell layer.

Tumor-Induced Osteomalacia Caused by a Phosphaturic Mesenchymal Tumor of the Sole Presenting as a Crippling Illness in a Postmenopausal Woman.

Tumor-induced osteomalacia, a rare and intriguing paraneoplastic syndrome that is usually caused by a phosphaturic mesenchymal tumor, leads to severe pain and hypophosphatemia. However, during clinical practice, most patients suffer from significant delay of diagnosis and treatment because the symptoms are similar to those of some very common diseases, such as osteoporosis and osteoarthritis. Moreover, physical complaints from postmenopausal women usually exacerbate the possibility of such delays.

Mannitol: physiological functionalities, determination methods, biotechnological production, and applications.

Mannitol is a naturally occurring six-carbon sugar alcohol that has wide applications in the food and pharmaceutical industry because of its many properties, namely being a natural sweetener with a low metabolism and no glycemic index. The increasing demand for mannitol has spurred many studies of its production. Compared with its chemical synthesis and extraction from plants, both of which are difficult to satisfy for industrial requirements, biotechnological production of mannitol has received considerably more attention and interest from scientists because of its known advantages over those two methods.

Trajectories of body mass index (BMI) and hypertension risk among middle-aged and elderly Chinese people.

This study aimed to identify heterogeneity in BMI trajectories and evaluate the impact of BMI trajectories on the risk of hypertension in middle-aged and elderly Chinese people. After data screening, 28, 706 residents' e-health records from 2010 to 2018, including basic personal information, lifestyle and health, were finally included in this population-based longitudinal study.
