4%, 62.9%, and 51.6% in the non-DAA group vs. 88.6%, 83.7%, and 83.7% in the DAA group (P=0.03). Multivariate analysis demonstrated donor female sex and DAA therapy as protective factors of graft survival.

Pre- or post-LT therapy with DAA in HCV-infected patients has achieved an almost overall SVR. The use of liver grafts >70 years in these patients treated with DAA was associated with significantly higher 5-year patient and graft survival in DAA group compared to non-DAA group. Thus, the introduction of DAA therapy has allowed the safe use of livers >70 years in HCV-positive recipients.

70 years in HCV-positive recipients.Chlorogenic acid (CGA) may provide an effective and safe option for tumor treatment. However, its application is limited because of short residence time in vivo and repeated administration required. A phospholipid-based in situ gel containing chlorogenic acid (CGA PG) was prepared via a simple way. The CGA PG exhibited good fluidity, easy injectability, high-drug-loading capacity, and suitable sustained-release behavior whether in vitro or in vivo. Furthermore, CGA PG could suppress tumor growth with no significant side effects. Overall, CGA PG may be a promising sustained drug delivery system with excellent therapeutic effect on glioma and hepatocellular carcinoma.Breast cancer, as a malignant disease that seriously threatens women's health, urgently needs to be researched to develop effective and safe therapeutic drugs. Nanoparticle drug delivery systems (NDDS), provide a powerful means for drug targeting to the breast cancer, enhancing the bioavailability and reducing the adverse effects of anticancer drug. However, the breast cancer microenvironment together with heterogeneity of cancer, impedes the tumor targeting effect of NDDS. Breast cancer microenvironment, exerts endogenous stimuli, such as hypoxia, acidosis, and aberrant protease expression, shape a natural shelter for tumor growth, invasion and migration. On the basis of the ubiquitous of endogenous stimuli in the breast cancer microenvironment, researchers exploited them to design the stimuli-responsive NDDS, which response to endogenous stimulus, targeted release drug in breast cancer microenvironment. In this review, we highlighted the effect of the breast cancer microenvironment, summarized innovative NDDS responsive to the internal stimuli in the tumor microenvironment, including the material, the targeting groups, the loading drugs, targeting position and the function of stimuli-responsive nanoparticle drug delivery system. The limitations and potential applications of the stimuli-responsive nanoparticle drug delivery systems for breast cancer treatment were discussed to further the application.

To evaluate the clinical safety and efficacy of EASYX, a new nonadhesive precipitating liquid embolic agent based on a polyvinyl alcohol ether polymer labeled with iodine molecules, for peripheral embolization.

This open-label prospective multicenter study was conducted on 50 consecutive patients treated with embolization using EASYX in 3 academic hospitals from April 2018 to July 2019. Indications for embolization were symptomatic varicocele (n= 15), type II endoleak (n= 8), acute hemorrhage (n= 16), portal vein embolization (PVE; n= 9), or angiomyolipoma (AML; n= 2). Patient characteristics, technical and clinical success rates, pain at injection, and satisfaction of the interventional radiologists were assessed. Follow-up imaging was performed using ultrasound for varicoceles (at 1 month) and computed tomography (CT) for the other indications (at 3 or 6 months).

The immediate technical success rate was 98%. The clinical success rates were 100% for acute hemorrhage and type II endoleaks, 89% for PVE, 86% for varicoceles, and 50% for AMLs. Patients who underwent PVE showed significant hypertrophy of the future liver remnant at follow-up (P < .001), and 55.6% of patients proceeded to hepatectomy. The absence of artifacts on imaging allowed improved monitoring of the aneurysmal sac in patients with type II endoleaks. The satisfaction rate of the interventional radiologists was >90% for 5 of 7 items.

EASYX as a novel copolymer liquid embolic agent was safe and efficient for peripheral embolization. The absence of tantalum allowed reduced CT artifacts on imaging follow-up, which was especially useful in patients with type II endoleaks.

This study focuses on the function of lysine acetyltransferase 1 (KAT1) in the progression of DR and the epigenetic mechanism. A mouse model with DR was induced by streptozotocin (STZ). Abundantly expressed genes in STZ-induced mice were analyzed. KAT1 was found to be significantly downregulated in the retinal tissues of model mice. Retinal microvascular endothelial cells (RMECs) and retinal Müller cells (rMCs) were cultured in high-glucose medium for in vitro studies. Upregulation of KAT1 suppressed inflammation, neovascularization, and vascular leakage in mouse retinal tissues, and it reduced the activity and inflammatory responses in rMCs, as well as the proliferation and metastatic potential of RMECs. KAT1 activated the transcription activity of YTHDF2 through histone acetylation of the promoter, and YTHDF2 triggered the instability of ITGB1 mRNA to induce mRNA degradation in an m6A manner. The activities of rMCs and RMECs were increased by sh-YTHDF2 but suppressed by sh-ITGB1. The FAK/PI3K/AKT signaling pathway was suppressed upon ITGB1 silencing. Collectively, this study demonstrated that KAT1 triggers YTHDF2-mediated ITGB1 mRNA instability to alleviate the progression of DR.Second-generation antipsychotics (SGAs) are first-line drugs that are prescribed for mental disorders in clinic. Severe cardiotoxicity has been widely reported and thus limits their clinical application. This study aimed to identify the common mechanism underlying SGAs-induced cardiotoxicity using dual-omics analyses. Balb/C mice were intraperitoneally injected with two representative SGAs, olanzapine (2.5 mg/kg) and clozapine (25 mg/kg), at clinically comparable doses for 0, 7, 14 and 21 days. Our results showed that both SGAs induced cardiomyocyte degeneration, inflammation infiltration, and cardiac fibrosis, all of which worsened with time. Proteomic analysis revelaed that 22 differentially expressed (DE) proteins overlapped in olanzapine and clozapine-treated hearts. These proteins were significantly enriched in muscle contraction, amino acid metabolism and spliceosomal assembly by GO term analysis and spliceosome signaling was among the top enriched pathways by KEGG analysis. Among the 22 DE proteins, three spliceosome signal proteins were validated in a dynamic detection, and their expression significantly correlated with the extent of SGAs-induced cardiac fibrosis. Following the spliceosome signaling dysregulation, RNA sequencing revealed that alternative splicing events in the mouse hearts were markedly enhanced by SGAs treatments, and the production of vast transcript variants resulted in dysregulation of multiple pathways that are critical for cardiomyocytes adaptation and cardiac remodeling. Pladienolide B, a specific inhibitor of mRNA splicing, successfully corrected SGAs-induced alternative splicing and significantly attenuated the secretion of pro-inflammatory factors and cell deaths induced by SGAs exposure. Our study concluded that the spliceosome signaling was a common pathway driving SGAs cardiotoxicity. Pharmacological inhibition of the spliceosome signaling represents a novel therapeutic strategy against SGAs cardiotoxicity.Cadmium (Cd) exposure can exert an impact on carcinogenicity of breast cancer, however, the mechanism is not fully understood in triple-negative breast cancer (TNBC). We performed a TNBC MDA-MB-231 cell model and assessed the toxic effect of Cd exposure (0, 10, 20, 50, 60, 80 μM). Cd reduced cell viability in a time- and dose-dependent manner, followed by cell cycle arrest in S phase with alterations of cyclin 1A1, cyclin 1D1 and CDK2. Lactate dehydrogenase (LDH) release, apoptosis and pyroptosis were increased, which were relieved by z-VAD. Elevated ROS and NLRP3, caspase-1, IL-1β and IL-18 were detected, which was attenuated by N-acetylcysteine. Increased bax and decreased caspase-8, caspase-9 and caspase-3 were found. gasdermin E (GSDME) was activated with cleavage of GSDME-NT, which was retarded by z-VAD. Additionally, p38 MAPK signaling pathway was activated. Our data demonstrate GSDME-activated pyroptosis in Cd toxicity, implying a potential impact on TNBC.Tachypleus amebocyte lysate (TAL) is crucial in medical testing, but its industry in China has been restricted due to the decline of horseshoe crab population in recent years. Exploring methods of enhancing immunity and rapid hemocytes proliferation is urgent for the industrial horseshoe crab culture. In this study, β-glucan (G), peptidoglycan (P), and squalene (S) were injected to horseshoe crabs at two concentrations (5 and 10 mg/kg), in order to compare their effects on total hemocyte count (THC), reactive oxygen species (ROS), and non-specific immune enzyme activities. Results showed that the THC, superoxide dismutase (SOD), catalase (CAT), and total antioxidant capacity (T-AOC) were significantly increased by three immunostimulants at different points of time; ROS was significantly increased except at two squalene groups; lysozyme (LZM) and alkaline phosphatase (AKP) activity were increased except at low dose (5 mg/kg) squalene group; malondialdehyde (MDA) activity was decreased in all treatments; and hemocyanin concentration (HC) changed little during the experiment. At the 48th hour, THC, ROS, SOD, CAT, T-AOC, LZM, and AKP activities were significantly higher in the two peptidoglycan groups than those in the control group; the low dose β-glucan and squalene groups showed significantly higher SOD and CAT, but their THC and AKP were not significantly different from those of the control group. In general, all three immunostimulants stimulated the hemolymph parameters of horseshoe crabs, notably, peptidoglycan could significantly increase the THC and enzyme activities, suggesting that peptidoglycan can be developed as an efficient immunostimulant for horseshoe crabs.Streptococcosis causes great economic losses in intensive culture of tilapia. Vaccination is the most effective and safest way to tackle infectious diseases. Thus, this study sought the more effective and safer antigenic fraction after sonication of Streptococcus agalactiae to elaborate a vaccine against streptococcosis in Nile tilapia. For this, twenty-one days after vaccination with different fractions (soluble and insoluble) of S. agalactiae, the fish were challenged with the homologous strain (LD50). Then, samples were taken at zero, 14, 28, 60 and 90 days post-vaccination (DPV, n = 7). SSR128129E ic50 Blood and organs (cranial kidney, spleen and liver) were collected from vaccinated and unvaccinated fish. Finally, insoluble fraction vaccine presented the best effect, resulting in a 100% relative percent of survival (RPS) and without clinical manifestations. In view of the results, it was to evaluate the role of the insoluble fraction of the antigen in the protective immunity against streptococcosis. The results indicate that the spleen might be the main organ in the vaccine response in Nile tilapia due to the great morphological and immunological differences in vaccinated fish, evidenced by the greater of melanomacrophage centers (MMC) and IgM + lymphocytes in relation to the non-vaccinated fish.
