BACKGROUND AND AIMS: Developing sparse panels of biomarkers for cardiovascular disease in type 2 diabetes would enable risk stratification for clinical decision making and selection into clinical trials. We examined the individual and joint performance of five candidate biomarkers for incident cardiovascular disease (CVD) in type 2 diabetes that an earlier discovery study had yielded. METHODS: Apolipoprotein CIII (apoCIII), N-terminal prohormone B-type natriuretic peptide (NT-proBNP), high sensitivity Troponin T (hsTnT), Interleukin-6, and Interleukin-15 were measured in baseline serum samples from the Collaborative Atorvastatin Diabetes trial (CARDS) of atorvastatin versus placebo...

Interleukin (IL)-11 plays an important role in the immune system. However, IL-11 has not yet been characterized in avian species, including chickens. This study is the first to clone and functionally characterize chicken IL-11 (chIL-11). Multiple alignments and phylogenetic tree comparisons of chIL-11 with IL-11 proteins from other species revealed high levels of conservation and a close relationship between chicken and Japanese quail IL-11. Our results demonstrate that chIL-11 was a functional ligand of IL-11RA and IL-6ST in chicken HD11 and OU2 cell lines, as well as activated and regulated JAK-STAT, NF-κB, PI3K/AKT, and MAPK signaling pathways in chicken cell lines...

Increasing evidence suggests that PGE2 metabolic pathway is involved in pathological changes of the secondary brain injury after traumatic brain injury. However, the underlying mechanisms, in particular, the correlation between various key enzymes and the brain injury, has remained to be fully explored. More specifically, it remains to be ascertained whether AH6809 (an EP2 receptor antagonist) would interfere with the downstream of the PGE2 , regulate the inflammatory mediators and improve neuronal damage in the hippocampus by PGE2 - EP2 - cAMP signaling pathway...

Delavatine A, an unusual isoquinoline alkaloid isolated from I. delavayi, was first studied for anti-inflammatory effect using lipopolysaccharide (LPS)-induced BV-2 microglia. In the present study, we found that delavatine A substantially suppressed the LPS-induced pro-inflammatory mediators, nitric oxide (NO), and tumor necrosis factor-a (TNF-a), interleukin-6 (IL-6), interleukin-1β (IL-1β) in BV-2 microglial cells. These effects resulted from the inhibition of their regulatory genes inducible NO synthase (iNOS), cycloxygenase-2 (COX-2) and TNF-a, IL-6, IL-1β...

INTRODUCTION: Although several techniques of laparoscopic left pancreatectomy have already been developed through experiments on animals and human patients, there is still insufficient information about their pathophysiological mechanisms, especially the impact on surgical stress. METHOD: In a group of 10 pigs, open left pancreatectomy was performed, and the other group of 10 pigs underwent laparoscopic left pancreatectomy. Postoperative stress was compared by determining serum levels of leukocytes, interleukin 1, 6 and CRP from peripheral venous blood collection...

Neutrophilic bronchiolitis is the primary lesion in asthma-affected horses. Neutrophils are key actors in host defense, migrating toward sites of inflammation and infection, where they act as early responder cells toward external insults. However, neutrophils can also mediate tissue damage in various non-infectious inflammatory processes. Within the airways, these cells likely contribute to bronchoconstriction, mucus hypersecretion, and pulmonary remodeling by releasing pro-inflammatory mediators, including the cytokines interleukin (IL)-8 and IL-17, neutrophil elastase, reactive oxygen species (ROS), and neutrophil extracellular traps (NETs)...

OBJECTIVES: No valid treatment modality that will repair stroke damage and provide neurological recovery has yet been identified in literature. Studies demonstrated that adequate quality of life could be provided if post-stroke pain could be treated sufficiently and timely. Besides its pain relief effects, tramadol has oedema-reducing and anti-inflammatory properties. With these in mind, this study investigated the influence of tramadol in acute and/or chronic ischaemia/reperfusion (I/R) injury...

The Src homology-2 domain protein B is an adaptor protein operating downstream of tyrosine kinases. The Shb gene knockout has been found to accelerate p210 Breakpoint cluster region-cAbl oncogene 1 tyrosine kinase-induced leukemia. In human myeloid leukemia were tumors with high Src homology-2 domain protein B mRNA content, tumors were, however, associated with decreased latency and myeloid leukemia exhibiting immune cell characteristics. Thus, the aim of this study was to investigate the effects of Shb knockout on the development of leukemia in three additional models, that is, colony stimulating factor 3 receptor-T618I-induced neutrophilic leukemia, p190 Breakpoint cluster region-cAbl oncogene 1 tyrosine kinase-induced B-cell leukemia, and G12D-Kras-induced T-cell leukemia/thymic lymphoma...

It is known that women develop alcoholic liver injury more rapidly and have a lower alcohol toxic threshold than men. However, the detailed molecular mechanisms remain unclear. The precise mechanism responsible for the sex difference needs to be determined. Female and male mice were given ethanol by intragastric infusion every day for 4 weeks. The pathological changes were detected by hematoxylin-eosin, Sirius red, oil red O, periodic acid-Schiff, and Hochest33258 staining in the liver of female and male mice...

Crocus sativus is a spice with various pharmacological properties. Crocin, picrocrocin, and safranal are the main compositions of saffron that have recently been considered in the therapy of many diseases. High-performance liquid chromatography analysis revealed presence of these compounds in our saffron extract. This study was carried out to evaluate the effect of saffron on burn wound healing at an in vivo model. Saffron was topically applied on burn wounds in rats; the percentage of wound closure, wound contraction, and the levels of main cytokines and growth factors were measured...

In this study, enzyme-assisted extraction was used to isolate functional polysaccharides from Korean ginseng (Panax ginseng Meyer) and the physicochemical and biological properties of the extracted polysaccharides were investigated, comparing with those from traditional hot-water extraction (FGWP). In macrophages, their effects on cytokines production could be ordered as FGEP-CA ≥ FGEP-A > FGEP-C > FGWP, suggesting that FGEP-CA (combined cellulase- and α-amylase-extracted polysaccharide) is a potent immunostimulator...

NLRP6, a member of the nucleotide-binding domain, leucine-rich repeat-containing (NLR) innate immune receptor family, has been reported to participate in inflammasome formation. Activation of inflammasome triggers a caspase-1-dependent programming cell death called pyroptosis. However, whether NLRP6 induces pyroptosis has not been investigated. In this study, we showed that NLRP6 overexpression activated caspase-1 and gasdermin-D and then induced pyroptosis of human gingival fibroblasts, resulting in release of proinflammatory mediators interleukin (IL)-1β and IL-18...

BACKGROUND: Interleukin-31 (IL-31), a novel T helper type 2 effector cytokine, is known to have an important effect on the pathogenesis of allergic disease and tumors. However, the impact of IL-31 on human lung cancer remains unclear. METHODS: This study explored the role of IL-31 polymorphisms in lung cancer and sought to characterize how IL-31 polymorphisms correlate with lung cancer tumorigenesis and patient survival rates. Using a single-nucleotide polymorphism genotype assay, we examined the expression of two IL-31 polymorphisms (rs7977932 and rs4758680) in samples from 302 lung cancer patients and 493 control cases...

It was demonstrated that isoflavones can cross the blood-brain barrier, making them desirable candidate agents for the prevention of neurological symptoms. 8-Hydroxydaidzein (8-OHD, 4',7,8-trihydoxyisoflavone) is an isoflavone found only in fermented soy food. Current results showed that 8-OHD inhibited LPS-stimulated production of nitric oxide (NO) and proinflammatory cytokines, such as tumor necrosis factor (TNF)-α and interleukin (IL)-6, by inhibiting gene expression in BV2 microglial cells. Moreover, 8-OHD markedly quenched reactive oxygen species (ROS) and activated NF-E2-related factor 2 (Nrf2) so as to upregulate expression of Phase II enzymes, including heme oxygenase (HO)-1, NAD(P)H quinone dehydrogenase 1 (NQO1), and the modifier subunit of glutamate cysteine ligase (GCLM)...

Acute kidney injury (AKI) is a leading cause of morbidity and mortality. Cisplatin is an effective chemotherapeutic agent whose administration is limited by nephrotoxicity. Therapies to prevent cisplatin-induced AKI are lacking. While tumor necrosis factor-α (TNF) plays a key role in the pathogenesis of cisplatin nephrotoxicity, the immune signaling pathways that trigger TNF generation in this context require elucidation. Sterile injury triggers the release and activation of both isoforms of interleukin(IL)-1, IL-1α and IL-1β, and stimulation of the interleukin-1 receptor (IL-1R1) by these ligands engages a pro-inflammatory signaling cascade that induces TNF induction...
