Electrochemical immunosensor with nanocellulose-Au composite assisted multiple signal amplification for detection of avian leukosis virus subgroup J.

A sensitive sandwich-type electrochemical immunosensor was developed for the detection of avian leukosis virus subgroup J (ALV-J), which benefitted from multiple signal amplification involving graphene-perylene-3,4,9,10-tetracarboxylic acid nanocomposites (GR-PTCA), nanocellulose-Au NP composites (NC-Au) and the alkaline phosphatase (ALP) catalytic reaction. GR-PTCA nanocomposites on glassy carbon electrodes served as the immunosensor platform. Due to their excellent electrical conductivity and abundant polycarboxylic sites, the GR-PTCA nanocomposites allowed fast electron transfer and good immobilization of primary antibodies, thereby affording a strong immunosensor signal in the presence of ALV-J. The detected signal could be further amplified by the introduction of NC-Au composites as a carrier of secondary antibodies (Ab2) and by harnessing the catalytic properties of Au and ALP. Under optimized testing conditions, the electrochemical immunosensor displayed excellent analytical performance for the detection of ALV-J, showing a linear current response from 10(2.08) to 10(4.0) TCID50/mL (TCID50: 50% tissue culture infective dose) with a low detection limit of 10(1.98) TCID50/mL (S/N = 3). In addition to high sensitivity, the immunosensor showed very good selectivity, reproducibility and operational stability, demonstrating potential application for the quantitative detection of ALV-J in clinical diagnosis.

Pinocembrin attenuates allergic airway inflammation via inhibition of NF-κB pathway in mice.

Pinocembrin, one of the primary flavonoids in propolis, possesses many biological activities, including anti-inflammation, anti-oxidation and immunoregulation. This study aimed to evaluate whether pinocembrin could attenuate ovalbumin (OVA)-induced allergic airway inflammation in mice and to explore the possible mechanism. BALB/c mice sensitized and challenged with OVA were administered intraperitoneally with pinocembrin. Airway inflammation and airway hyperresponsiveness were examined. T-helper type (Th) 2 cytokines in bronchoalveolar lavage fluid (BALF) and OVA-specific immunoglobulin E (IgE) in serum were determined. The activation of nuclear factor kappa B (NF-κB) p65 were also measured. Our results showed that pinocembrin resulted in significant inhibition of pathophysiological signs of allergic asthma, including increased pulmonary eosinophilia infiltration, mucus hypersecretion and airway hyperresponsiveness (AHR). Treatment with pinocembrin significantly reduced Th2 cytokines interleukin (IL)-4, IL-5 and IL-13 in BALF, and OVA-specific IgE in serum. Moreover, pinocembrin treatment suppressed phosphorylation of inhibitor-κBα (IκBα) and NF-κB subunit p65 activation in lung tissue of OVA-sensitized mice. These data suggest that pinocembrin may inhibit allergic airway inflammation, and providing potential benefits in the treatment of inflammatory disease.

A mannose-specific C-type lectin from Fenneropenaeus merguiensis exhibited antimicrobial activity to mediate shrimp innate immunity.

Being one type of pattern recognition receptors (PRRs), lectins exhibit a crucial role in the defense mechanism of invertebrates which are deficient in an adaptive immune system. A new C-type lectin called FmLC3 was isolated from hepatopancreas of Fenneropenaeus merguiensis by cloning approaches, RT-PCR and 5' and 3' RACE (rapid amplification of cDNA ends). A full-length cDNA of FmLC3 contains 607 bp with one open reading frame of 480bp, encoding a 159-amino acids peptide. The predicted primary structure of FmLC3 is composed of a signal peptide, a carbohydrate recognition domain with an EPN motif and one Ca(2+) binding site-2, including a double-loop region assisted by two conserved disulfide linkages. FmLC3 had a molecular mass of 17.96kDa and pI of 4.92. In normal or unchallenged shrimp, the mRNA expression of FmLC3 was detected only in hepatopancreas whilst its native proteins were found in hemolymph, heart, stomach and intestine but not in the expressed tissue, indicating that after being synthesized in hepatopancreas, FmLC3 would be secreted to other tissues. The significant up-regulation of FmLC3 was manifested in shrimp challenged with Vibrio harveyi or white spot syndrome virus. After knockdown with gene-specific double-stranded RNA and following by co-pathogenic inoculation, the FmLC3 expression was severely suppressed with coherence of increasing in cumulative mortality and reduction of the median lethal time. Recombinant FmLC3 (rFmLC3) had agglutinating activity towards diverse bacterial strains in a Ca(2+)-dependent manner. Its activity was inhibited by lipopolysaccharide and mannose, implying that FmLC3 was mannose-binding C-type lectin. Moreover, rFmLC3 could bind directly to various microbial strains with Ca(2+)-requirement. Otherwise, rFmLC3 exhibited the antimicrobial activity by inhibiting effectively the microbial growth in vitro. All these results signified that FmLC3 might act as PRR to recognize with a broad specificity for diverse pathogens, and contribute in shrimp immune response via the agglutination, binding and antimicrobial activity.

Nigella Sativa Oil Protects the Rat Ovary from Oxidative Injury Due to Ischemia-Reperfusion.

BACKGROUND The aim of this study was to evaluate the effects of Nigella sativa (N. sativa) oil (NSO) on ovarian oxidative damage following ischemia-reperfusion injury, using a rat model of ovarian torsion. MATERIAL AND METHODS Forty-eight female albino Wistar rats were divided into six groups: (Group 1) laparotomy only; (Group 2) intraperitoneal NSO (2 ml/kg), 1 hour following laparotomy; (Group 3) 3 hours of ovarian ischemia; (Group 4) 3 hours of ovarian ischemia followed by 3 hours of reperfusion; (Group 5) 3 hours of ovarian ischemia and 2 ml/kg of NSO 1 hour before laparotomy; (Group 6) 3 hours of reperfusion after 3 hours of ovarian ischemia and 2 ml/mg of NSO 1 hour before laparotomy. RESULTS The antioxidant status, ceruloplasmin level, native thiol, total thiol, and disulfide levels of the control group (Group 1) were significantly increased compared with the ovarian ischemia-reperfusion group treated with NSO (Group 6) (p=0.003, p=0.002, p=0.006, p=0.001 and p=0.003, respectively); these levels in the ovarian ischemia group (Group 3) and ischemia-reperfusion group (Group 4) were statistically similar to those of the ovarian ischemia + NSO group (Group 5) and ovarian ischemia-reperfusion + NSO group (Group 6). CONCLUSIONS In this preliminary rat study, administration of NSO shortly after the onset of ovarian ischemia-reperfusion injury, did not significantly reduce levels of markers of oxidative injury. Further studies are required to evaluate the ovarian changes at the tissue level, and to determine the optimum dose of NSO.

Evaluation of the antioxidant impact of ginger-based kombucha on the murine breast cancer model.

Background Abnormal metabolism is a common event in cancerous cells. For example, the increase of reactive oxygen species (ROS) production, particularly due to aerobic respiration during invasive stage, results in cancer progression. Herein, the impact of kombucha tea prepared from ginger on the alteration of antioxidant agents was assessed in the breast cancer animal model. Methods Two types of kombucha tea with or without ginger were administered to BALB/c mice before and after tumor challenge. Superoxide dismutase (SOD), catalase, glutathione (GSH) and malondialdehyde (MDA) were evaluated in tumor, liver and kidney. Results Administration of kombucha ginger tea significantly decreased catalase activity as well as GSH and MDA level in tumor homogenate (p<0.001). A significant decrease in SOD activity and increase in MDA quantity was determined in the kidney which had received kombucha ginger tea (p<0.01). Conclusions The consumption of kombucha prepared from ginger could exert minor antioxidant impacts by balancing multi antioxidant factors in different tissues in the breast cancer models.

Morphological analysis of the male reproductive accessory glands of the bat Artibeus lituratus (Phyllostomidae: Chiroptera).

Bats are distributed worldwide from tropical to temperate regions. Despite their wide geographical radiation and advances in studies using evolutionary approaches, aspects related to the reproduction of these animals remain poorly explored, especially those related to the male reproductive accessory glands (RAGs). Thus, the aim of this study was to analyze the morphophysiology of the male RAGs in the bat Artibeus lituratus. The RAGs in A. lituratus are composed of a compact intra-abdominal glandular complex, consisting of the prostate with two prostatic regions (ventral and dorsal), plus Littre glands and a pair of extra-abdominal bulbourethral glands. The ventral region of the prostate has an epithelium with variable morphology, due to its holocrine type of secretion. In contrast, the dorsal region has a typical cubic-to-columnar pseudostratified epithelium. Both regions contain two cell types, basal and secretory cells. Similar to the epithelial morphology, the secretion also varies, with the ventral region containing numerous PAS-positive globular vesicles, whereas the dorsal region has a more fluid, hyaline and PAS-negative secretion. Littre glands are dispersed in the connective tissue of the urethra, while the bulbourethral glands are located in the penile root, both glands with cubic-to-columnar pseudostratified epithelium and globular PAS-positive secretion. The results demonstrate that the RAGs of A. lituratus are composed of two prostatic regions, ventral and dorsal, and urethral and bulbourethral glands, with no seminal vesicles. Each prostatic region has unique and distinctive characteristics, with the ventral region presenting an exclusive holocrine nature and the dorsal region having similarities to the ventral prostate of rodents.

Effects of a bone graft substitute consisting of porous gradient HA/ZrO2 and gelatin/chitosan slow-release hydrogel containing BMP-2 and BMSCs on lumbar vertebral defect repair in rhesus monkey.

Dense biomaterial plays an important role in bone replacement. However, it fails to induce bone-cell migration into graft material. In the present study, a novel bone-graft substitute (BGS) consisting of porous gradient HA/ZrO2 composite (PGHC) and gelatin/chitosan slow-release hydrogel containing BMP-2 and BMSCs was designed and prepared to repair lumbar vertebral defects. The morphological characteristics of the BGS evaluated by scanning electron microscope showed that it had a three-dimensional network structure with uniformly distributed chitosan microspheres on the surfaces of the graft material and the interior of the pores. Then, BGS (group A), PGHC (group B), or autologous bone (group C) was implanted into lumbar vertebral body defects in a total of 24 healthy rhesus monkeys. After 8 and 16 weeks, anteroposterior and lateral radiographs of the lumbar spine, micro-computed tomography (micro-CT), histomorphometry, biomechanical testing, and biochemical testing for bone-matrix markers, including type I collagen, osteocalcin, osteopontin, basic fibroblast growth factor, alkaline phosphatase, and vascular endothelial growth factor, were performed to examine the reparative efficacy of the BGS and PGHC. The BGS displayed excellent ability to repair the lumbar vertebral defect in the rhesus monkey. Radiography, micro-CT scanning, and histomorphological characterization showed that the newly formed bone volume in the interior of the pores in the BGS was significantly higher than in the PGHC. The results of biomechanical testing indicated that the vertebral body compression strength of the PGHC implant was lower than the other implants. RT-PCR and western-blot analyses showed that the expression of bone-related proteins in the BGS implant was significantly higher than in the PGHC implant. The BGS displayed reparative effects similar to autologous bone. Therefore, BGS use in vertebral bone defect repair appears promising.

Vascular endothelial growth factor (VEGF)-related single nucleotide polymorphisms rs10738760 and rs6921438 are not associated with diabetic retinopathy (DR) in Slovenian patients with type 2 diabetes mellitus (T2DM).

Diabetic retinopathy (DR) is a complication of diabetes characterized by vascular permeability, increased tissue ischemia, and angiogenesis. One of the most important proteins involved in angiogenesis is vascular endothelial growth factor (VEGF, also known as VEGFA). A previous study demonstrated that two single nucleotide polymorphisms (SNPs), rs6921438 and rs10738760, account for nearly half the variation in circulating VEGF levels. The aim of our study was to assess the association between rs6921438 and rs10738760 and DR in Slovenian patients with type 2 diabetes mellitus (T2DM). This case-control study enrolled 1037 unrelated Slovenian individuals (Caucasians) with T2DM. DR group included 415 T2DM patients with DR, while control group included 622 T2DM patients with no clinical signs of DR. The clinical and laboratory data were obtained from the medical records of the patients. The genotyping of rs6921438 and rs10738760 SNPs was carried out with real-time PCR assays. Significant differences were observed between patients with DR and controls in the duration of diabetes (p < 0.001), insulin therapy (p < 0.001), glycated hemoglobin (p = 0.001), body mass index (p = 0.002), total cholesterol (p = 0.002), and low-density lipoprotein cholesterol (p < 0.001). However, we did not observe significant differences in the genotype and allele distribution of the two SNPs, between DR and control group (p < 0.05). Logistic regression analysis showed that rs6921438 and rs10738760 were not independent genetic risk factors for DR in the co-dominant model adjusted for the above-mentioned clinical and laboratory data. In conclusion, VEGF-related SNPs rs10738760 and rs6921438 are not associated with DR in our group of Slovenian patients (Caucasians) with T2DM.

Inhaled Cryptococcus neoformans Elicits Allergic Airway Inflammation independent of NFκB signaling in lung epithelial cells.

Pulmonary challenge with the ubiquitous fungus Cryptococcus neoformans results in allergic airway inflammation (AAI) characterized by robust recruitment of eosinophils and T-cells producing type 2 cytokines to the lungs. Previous studies have demonstrated a critical role for NFκB activation within lung epithelial cells (LECs) in driving AAI in response to protein allergens, yet the role of LEC-intrinsic NFκB in promoting AAI following exposure to C. neoformans is poorly understood. To investigate the role of LEC-intrinsic NFκB in promoting AAI following C. neoformans challenge, we utilized IKK(∆)(LEC) mice, which lack canonical NFκB activation specifically within LECs. IKK(∆)(LEC) and littermate control mice were intranasally challenged with 10(6) CFU of C. neoformans strain 52D, and lung tissues collected at 7, 14, and 21 days post infection to assess the development of AAI. Notably, the absence of epithelial NFκB signaling did not affect the magnitude or kinetics of lung eosinophilia when compared to the response in wild-type control mice. The total numbers of lung T-cells producing the type 2 cytokines IL-5 and IL-13 also were unchanged in IKK(∆)(LEC) mice. Furthermore, IKK(∆)(LEC) mice showed no defect in the recruitment of protective IFNγ-producing CD4 T-cells to the lungs, fungal clearance, or host survival as compared to controls. Immunofluorescence imaging surprisingly revealed no evidence of nuclear localization of NFκB in LECs in response to C. neoformans challenge, indicating that NFκB is not activated within these cells. Taken together, these data strongly suggest that NFκB signaling within LECs does not promote AAI observed in response to C. neoformans. This article is protected by copyright. All rights reserved.
