Histological evaluation confirmed the presence of atherosclerotic lesions and the co-localization of SQRho bioconjugates at the lesion sites. In the last decade 3D printing (3DP) technology has gained increasing interest in the pharmaceutical field addressing several novel challenges such as on-demand manufacturing at the point of need, customization of drug release profiles and patient-specific solutions as well as combinations of several APIs in one dosage form. Therefore, 3DP can become a new and promising path to drug product development and manufacturing, able to support specific therapies and improve compliance, safety and effectiveness. The aim of this work was to partially coat tablets with a glyceride, namely Precirol ATO 5 using a semi-solids 3D printer as an approach for tuning the release of two Active Pharmaceutical Ingredients (APIs), the hydrophilic methyl-levodopa hydrochloride (Melevodopa) and the lipophilic Acyclovir. Various parameters of the 3DP coating process were purposefully modified using experimental design techniques in order to customize the selected APIs release profile, without affecting the core composition of the formulation. The percentage of the tablet surface coated, the number of coating layers as well as the coated sides of the tablet where the parameters which controlled the release profile for both APIs. Different dissolution profiles have been achieved by tuning these simple parameters, which revealed a non-Fickian release mechanism regardless of the API. Ketamine in sub-anaesthetic doses is an analgesic adjuvant with a morphine-sparing effect. Co-administration of a strong opioid with an analgesic adjuvant such as ketamine is a potential treatment option, especially for patients with cancer-related pain. A limitation of ketamine is its short in vivo elimination half-life. Hence, our aim was to develop biocompatible and biodegradable ketamine-loaded poly(ethylene glycol) (PEG)-block-poly(lactic-co-glycolic acid) (PLGA) nanoparticles for sustained release. Ketamine-encapsulated single polymer PEG-PLGA nanoparticles and double polymer PEG-PLGA/shellac (SH) nanoparticles with a high drug loading of 41.8% (drug weight/the total weight of drug-loaded nanoparticles) were prepared using a new sequential nanoprecipitation method. These drug-loaded nanoparticles exhibited a sustained-release profile for up to 21 days in vitro and for more than 5 days after intravenous injection in mice. Our study demonstrates that high drug loading and a sustained release profile can be achieved with ketamine-loaded PEG-PLGA nanoparticles prepared using this new nanoprecipitation method. AIM To investigate the effects of linagliptin treatment on hepatic energy metabolism and ER stress in high-fat-fed C57BL/6 mice. METHODS Forty male C57BL/6 mice, three months of age, received a control diet (C, 10% of lipids as energy, n = 20) or high-fat diet (HF, 50% of lipids as energy, n = 20) for 10 weeks. The groups were randomly subdivided into four groups to receive linagliptin, for five weeks, at a dose of 30 mg/kg/day added to the diets C, C-L, HF, and HF-L groups. RESULTS The HF group showed higher body mass, total and hepatic cholesterol levels and total and hepatic triacylglycerol levels than the C group, all of which were significantly diminished by linagliptin in the HF-L group. The HF group had higher hepatic steatosis than the C group, whereas linagliptin markedly reduced the hepatic steatosis (less 52%, P  less then  0.001). The expression of Sirt1 and Pgc1a was more significant in the HF-L group than in the HF group. Linagliptin also elicited enhanced GLP-1 concentrations and a reduction in the expression of the lipogenic genes Fas and Srebp1c. Besides, HF-L showed a reduction in the genes related to endoplasmic reticulum stress Chop, Atf4, and Gadd45 coupled with reduced apoptotic nuclei immunostaining. CONCLUSION Linagliptin caused a marked reduction in hepatic steatosis as a secondary effect of its glucose-lowering property. NAFLD countering involved reduced lipogenesis, increased beta-oxidation, and relief in endoplasmic reticulum stress, leading to reduced apoptosis and better preservation of the hepatic structure. Therefore, linagliptin may be used, preferably in diabetic patients, to avoid the progression of hepatic steatosis. Continuously elevated levels of growth hormone (GH) during life in mice are associated with hepatomegaly due to hepatocytes hypertrophy and hyperplasia, chronic liver inflammation, elevated levels of arachidonic acid (AA) at young ages and liver tumors development at old ages. In this work, the hepatic expression of enzymes involved in AA metabolism, cPLA2α, COX1 and COX2 enzymes, was evaluated in young and old GH-transgenic mice. Mice overexpressing GH exhibited higher hepatic expression of cPLA2α, COX1 and COX2 in comparison to controls at young and old ages and in both sexes. In old mice, when tumoral and non-tumoral tissue were compared, elevated expression of COX2 was observed in tumors. In contrast, exposure to continuous lower levels of hormone for a short period affected COX1 expression only in males. Considering the role of inflammation during liver tumorigenesis, these findings support a role of alterations in AA metabolism in GH-driven liver tumorigenesis. Sustained Ca2+ burst signaling is crucial for endothelial vasodilator production and is disrupted by growth factors and cytokines. Conjugated linoleic acid (CLA), a Src inhibitor in certain preparations, is generally regarded as safe during pregnancy by the FDA. Multiple CLA preparations; t10, c12 or c9, t11 CLA, or a 11 mixture of the two were administered before growth factor or cytokine treatment. Growth factors and cytokines caused a significant decrease in Ca2+ burst numbers in response to ATP stimulation. Both t10, c12 CLA and the 11 mixture rescued VEGF165 or TNFα inhibited Ca2+ bursts and correlated with Src-specific phosphorylation of connexin 43. VEGF165, TNFα, and IL-6 in combination at physiologic concentrations revealed IL-6 amplified the inhibitory effects of lower dose of VEGF165 and TNFα. Again, the 11 CLA mixture was most effective at rescue of function. Therefore, CLA formulations may be a promising treatment for endothelial dysfunction in diseases such as preeclampsia. Sexual differentiation and ovotestis development are closely associated with cortisol levels, the principal indicator of stress, via the glucocorticoid receptor (GR) in teleosts. Thus, GR is regarded as a mediator to expound the relationship between social stress and gonad development. In the present study, two gr genes (gr1 and gr2) were cloned and analyzed from a protandrous hermaphroditic teleost, the yellowtail clownfish (Amphiprion clarkii). GR1 was found to display a conserved nine-amino-acid insert, WRARQNTDG, between two zinc finger domains. The phylogenetic tree of GR showed that yellowtail clownfish GR1 and GR2 are clustered to teleost GR1 and teleost GR2 separately, and differ from tetrapod GR. The result of real-time PCR revealed that high-level gr1 was mainly distributed in the cerebellum, hypothalamus and heart. The gr2 gene was abundant in the pituitary and liver of females and nonbreeders, while gr2 was mainly detected in the medulla oblongata and middle kidney of males. Moreover, GRs can be expressed in cultured eukaryotic cells and functionally interact with dexamethasone (exogenous glucocorticoid), thereby triggering downstream signaling pathways of different potentials. GR1 and GR2 can be activated by 10 nM dexamethasone treatment in HEK-293T cells. Notably, real-time PCR analysis among three social status groups demonstrated that gr2 expression was the highest in the hypothalamus of nonbreeders, but gr1 was no difference. We speculate that social stress would increase the expression of gr2 gene expression in the hypothalamus to inhibit sexual development. These data provide evidence of social stress involving reproductive regulation, which may help to elucidate the underlying mechanism of sex differentiation and change. Diabetic retinopathy (DR)is a common diabetes complication, resulting in the loss of vision. circRNAshave been reported to serve as ceRNA via targeting corresponding miRNAs and modulating mRNA expression in various diseases. Recently, increasing reports has indicated circRNAs can exert a significant role inDR progression. However, the expression and mechanism of hsa_circ_0041795 in human retinal pigment epithelial cells ARPE-19 treated by high glucose remains poorly known. Hence, we aimed to work figure out the effect of hsa_circ_0041795 in high glucose (HG)-induced ARPE-19 cell damage and study its molecular mechanisms. In our current research, we found that hsa_circ_0041795 was obviously up-regulated in HG-treated ARPE-19 cells. High dose of glucose greatly depressed ARPE-19 cell survival and contributed to cell apoptosis. In addition, we observed that loss of hsa_circ_0041795 enhanced cell proliferation and inhibit ARPE-19 cell apoptosis, after HG incubation. Furthermore, data of ELISA indicated that hsa_circ_0041795 siRNA significantly restrained inflammatory factors expression, such as TNF-α, IL-1β and IL-6 in ARPE-19 cells treated with HG. miR-646 has been recognized in multiple diseases and currently, we predicted that miR-646 acted as a target of hsa_circ_0041795. Moreover, we found that miR-646 inhibitors dramatically reversed the effect of hsa_circ_0041795 siRNA on ARPE-19 cells. Additionally, a dual-luciferase reporter assay proved that VEGFC was a direct target of miR-646. Our results demonstrated that hsa_circ_0041795 might exhibit a novel therapeutic potential in the treatment of DR. V.Circular RNAs (circRNAs), a novel branch of noncoding RNAs, are widespread in eukaryotic cells. Particularly, due to their abilities to bind microRNA (miRNA) and serve as „sponges”, circRNAs can regulate gene expression and participate in multiple biological processes. To detect the function of the circRNAs in tomato resistance, in our study, high-throughput sequencing were used to detect the circRNAs in tomatoes before and after Phytophthora infestans (P. infestans) infection. A total of 68 circRNAs were identified, of them, 18 (26%) were termed as exonic circRNAs, 33 (49%) were termed as intergenic circRNAs, 17 (25%) were termed as intronic circRNAs. Thirty-six out of 68 circRNAs differentially expressed in tomatoes after infection, including 9 up- and 27 down-regulated. Among the up-regulated circRNAs, two exoinc circRNAs, circRNA45 and circRNA47 were annotated as whitefly-induced gp91-phox and ethylene-forming enzyme, respectively. Both of them could act as miR477-3p sponge. Transgenic plants transiently overexpressed circRNA45 and circRNA47 both displayed smaller lesion area than the control plants upon infection, accompanied by lower expression levels of miR477-3p. Furthermore, transiently overexpression of miR477-3p in tomatoes leading to a decline in their targeted disease related genes expression. Our results firstly identified circRNAs in tomato upon P. infestans infection and demonstrated that circRNA45 and circRNA47 may act as positive regulators in tomato resistance by regulating miRNA-mRNAs expression levels.
