The current study was aimed to investigate the involvement of endoplasmic reticulum stress (ERS)-mediated protein kinase R-like endoplasmic reticulum kinase (PERK) signaling in advanced glycation end products (AGEs)-exacerbated coronary microvascular dysfunctions (CMD) in non-obstructive coronary artery disease (NoCAD). ob/ob mice were used as NoCAD animal model which were exposed to AGEs by intraperitoneal injections. Animal CMD was evaluated by coronary flow velocity reserve (CFVR). A viral vector carrying perk-siRNA was used to silence PERK in vivo and in vitro studies. Cell apoptosis was detected by TUNEL. Immunofluorescent staining was used to assess CD42c-positive cell number in cardiac sections and NFATc4 translocation in CMECs. Real-time PCR and Western blotting were used to evaluate the gene expression levels. Cytokine and AGEs concentrations were determined by ELISA. Enzymatic activity of CaN was measured by a colorimetric method. A registered cross sectional study consisted of 77 patients dian CMECs. IMR values increased significantly in NoCAD patients complicated with diabetes, which were significantly and positively correlated with serum AGEs concentrations. Diabetes was associated with CMD in NoCAD. AGEs fostered in diabetes exacerbated CMD by activating ERS-mediated PERK/CaN/NFATc4 signaling in CMECs. IMR values increased significantly in NoCAD patients complicated with diabetes, which were significantly and positively correlated with serum AGEs concentrations.Algae are omnipresent in all seas and oceans, which make thema target for many applications such as bio-fertilizers, fish feeding and removal of heavy metals. In the present study, different algal species were examined as sustainable alternatives substrates for PHA production by Halomonas sp. Several media simulations were utilized to achieve high polymer productivity. The maximum poly(3-hydroxybutyrate) (PHB) concentrations were determined by using Corallina mediterranea hydrolysates as a carbon and nitrogen source. The isolates Halomonas pacifica ASL10 and Halomonas salifodiane ASL11 were found to be able to produce PHA by 67 % wt and 63 % wt CDW, respectively. PHB nanoparticles (NPs) had high zeta potential values and small particle sizes. These properties make it suitable for several drug delivery and pharmaceutical applications. Interestingly, NPs showed a potent antibacterial activity against several reference strains. The antibacterial efficacy of PHA-NPs has not been previously studied, thus this study opens a promising use of PHA-NPs.A novel glucose oxidase (GOD)-perhydrolase-in situ chemical oxidation (ISCO) cascade reaction system was designed, optimized, and verified the operation feasibility in this research. Among the determined four perhydrolases, acyltransferase from Mycobacterium smegmatis (MsAcT) displayed the highest specific activity for perhydrolysis reaction (76.4 U/mg) and the lowest Km value to hydrogen peroxide (13.9 mmol/L). GOD-MsAcT cascade reaction system also displayed high catalytic efficiency. Under the optimal parameters (501 activity unit ratio of GOD to MsAcT, pH 8.0, 50 mmol/L of β-d-glucose, and 15 mmol/L of glyceryl triacetate), the melanin decolorization rate using GOD-MsAcT-ISCO cascade reaction system reached 86.8 %. Kinetics of GOD-MsAcT-ISCO cascade reaction system for melanin decolorization fitted the kinetic model of Boltzmann sigmoid. As a substitutive skin whitening technology, GOD-MsAcT-ISCO cascade reaction system displayed an excellent application prospect.Ganoderic acids (GAs) produced by Ganoderma are a type of lanostane-type triterpenoids with anticancer and antimetastatic activities; however, low production of GAs limits its wide application. In this study, a novel strategy by promoting sporulation of Ganoderma was developed to increase GA production. First, a high-spore producing Ganoderma strain G. 260125 was obtained from dikaryotic strain CGMCC 5.0026, and the sporulation-sp
