While desirably high levels of lidocaine were achieved in the peritoneal space these were several orders of magnitude higher than blood levels, which remained well below toxic levels. A pharmacokinetic model is presented that incorporates in vitro release data to describe lidocaine concentrations in both peritoneal and plasma compartments, predicting similar release to that suggested by lidocaine concentrations remaining in the device after 3 and 7 days in situ. Histological analysis revealed similar inflammatory responses following implantation of the co-extruded implant and a commercially used silicone drain after three days. This non-opioid analgesic implant provides sustained release of lidocaine in an ovine model and is suitable for moving onto first in human trials.Nitric oxide (NO)-based gas therapy is emerged as a new adjunct anti-tumor treatment method, which has triggered a great research interest. Nevertheless, due to the short half-life of NO gas in vivo, it is of significance to develop NO-gas based gasotransmitter with controllable NO release for deep-tissue anti-tumor therapy. Herein, a novel soft X-ray activated persistent luminescence nanotransducer is designed for controllable and long-lasting NO release and deep-tissue anti-cancer therapy by integrating ZnGa2O4Mn (ZGOMn) nanoparticles with light-responsive NO donor (RBS). With the merits of the ultra-low dosage (down to 0.9 mGy) soft X-ray activated persistent luminescence from small sized ZGOMn, continuous NO release is achieved for about 40 min after stopping the irradiation of X-ray. Moreover, the green persistent luminescence can be renewably activated by in-situ soft X-ray irradiation, leading to the repeatable long-lasting NO release in deep tissue (up to 24 mm). And the designed NO-releasing platform presents efficient in vitro and in vivo anti-cancer therapy. https://www.selleckchem.com/products/bupivacaine.html Therefore, the designed persistent luminescence-based NO gasotransmitter provides a new NO-releasing strategy for depth-independent gas-sensitized therapeutic applications.Although graphene oxide (GO) possesses many beneficial functionalities for biomedical usage as itself, modification of GO surface with several polymers or protein is inevitable for in vivo applications; however, such modification limits the degradability of GO due to the steric hindrance. In that context, designing of a surface modified GO carrier that is going to be degraded after its biological function (i.e., drug delivery) is highly desired, especially at complex in vivo level. Herein, we design an unprecedented "catalytic GO nanomedicine" by applying the catalytic DNA, achieving self-degradation of GO in systemic level in the body after the therapy following surface modification. Once the catalytic GO nanomedicines are taken up by mucin1 (MUC1) aptamer-facilitated endocytosis, a photo-switch triggers the release of doxorubicin from the DNA. The single stranded G-quadruplex sequence on the surface of GO forms a quartet structure and becomes DNAzyme by binding with hemin on the GO surface, exhibiting peroxidase effect. Due to the high H2O2 concentration in cancer cells, the catalytic GO nanomedicine generates sufficient amount of strong oxidant, hypochlorous acid (HOCl), inducing GO degradation into small fragments for potential clearance. We demonstrate the potential of our catalytic GO nanomedicine for both therapy and degradation at cellular and complex in vivo environment.Non-alcoholic fatty liver(NAFLD) is prevalent in Asians despite the low obesity rate. We hypothesized that the haplotype of genetic variants in the 22q13 loci has a strong association with non-alcoholic fatty liver disease (NAFLD) that can be identified by genome-wide association study and that lifestyles may interact with the haplotype. We tested the hypothesis in middle-aged and elderly adults in a large city hospital-based cohort from the KoGES study. Men and women diagnosed with fatty liver, but who respectively consumed over 40 and 30 g ethanol per day were excluded. The haplotype of the selected SNPs from the 22q13 loci that influences NAFLD risk was generated. Among the 27374 participants, 1486 (5.4%) were diagnosed with NAFLD. LARGE_rs240072, RBFOX2_rs11089778, TRIOBP_rs12628603, PNPLA3_rs738409, and PARVB_rs2073080 in the 22q13 loci were included in the haplotype. Participants with the minor haplotype had 1.8, 2.3, and 1.8 times higher in the risk for NAFLD and serum AST and ALT activities, respectively, than those with the major haplotype. BMI, waist circumferences, serum glucose concentrations, and blood pressure interacted with the haplotype for NAFLD risk. We also found that a high carbohydrate intake and a dietary pattern characterized by high noodle and meat consumption significantly interacted with the minor haplotype to increase the risk of NAFLD. We hypothesized that the high incidence of NAFLD among Koreans, despite a relatively low incidence of obesity, might be due to genetic factors and perhaps their interactions with dietary patterns. The hypothesis was accepted since this study confirmed that participants with the minor allele of the haplotype in the 22q13 loci had a higher NAFLD risk that was exacerbated by high intakes of carbohydrates and a dietary pattern characterized by high noodle and meat consumption.Queen Garnet plum (QGP), known for its high levels of anthocyanins, is a hybrid of the Japanese plum developed in Queensland, Australia. Anthocyanins provide the red, blue, and purple pigments in plants with demonstrated beneficial health effects. This study hypothesized that low-dose anthocyanin QGP intake will have a significant positive effect on cognition, blood pressure, and gut microbiota in healthy older adults. A randomized crossover trial was conducted to determine the effect and within subject variance on cognition and 24 hr. ambulatory blood pressure in older adults without cognitive impairment following daily consumption of 200 mL low-dose anthocyanin (5 mg/100 g) QGP nectar (intervention) or raspberry cordial (control). Secondary outcomes included inflammatory markers (C-reactive protein), nerve growth factor (BDNF), and gut microbiota (16S rRNA gene sequencing). Twenty-eight participants (55+ years) were recruited. Each randomized treatment arm lasted for 8 weeks with a 4-week washout period. Cognition, blood pressure, and urine samples were measured at each visit (5 total) while blood and fecal samples were collected at baseline, 8 weeks, and 20 weeks.
