Under normal physiological conditions, microglial activation is tightly regulated by the neurons although the underlying mechanism remains elusive. Using published single-cell RNA sequencing data sets, we found that immune regulatory molecules including CD200, CD47, CX3CL1, TGFβ, and complement inhibitor CD59a are expressed by various retinal neurons. Importantly, we found that photoreceptors express higher levels of CD47 and CD59a, which was further confirmed in cultured 661W cells, WERI-Rb1 cells, and microdissected photoreceptors from human eyes. The expression of CD59a mRNA in 661W cells was upregulated by TNFα and hypoxia, whereas LPS, hypoxia, and IL-4 upregulated CD47 mRNA expression in 661W cells. Immunofluorescence staining detected strong CD59a immunoreactivity in the outer nuclear layer, inner/outer segments, and discrete staining in ganglion cell layer (GCL), inner plexiform layer (IPL), and outer plexiform layer. The expression of CD59a in photoreceptors was increased in the detached retina, but decreased in retinas from experimental autoimmune uveoretinitis (EAU) mice. In EAU retina, CD59a was highly expressed by active immune cells. CD47 was detected in GCL, IPL, and inner nuclear layer and some photoreceptors. The expression of CD47 in photoreceptors was also increased in the detached retina but decreased in EAU retina. In a coculture system, 661W enhanced arginase-1 and reduced IL-6 mRNA expression in BV2 microglial cells. Our results suggest that photoreceptors express immune regulatory molecules and may have the potential to regulate immune activation in the outer retina/subretinal space under pathophysiological conditions. © 2020 Wiley Periodicals, Inc.Benzo[a]pyrene (B[a]P), a typical carcinogenic polycyclic aromatic hydrocarbon, exists worldwide in vehicle exhaust, cigarette smoke and other polluted environments. Recent studies have demonstrated a strong association between B[a]P and lung cancer. However, whether B[a]P at human blood equivalent level can promote epithelial-mesenchymal transition (EMT), a crucial molecular event during cell malignant transformation, remains unclear. Besides, whether B[a]P facilitates this progress via aryl hydrocarbon receptor (AhR) signaling pathway also lacks scientific evidence. In our study, the transwell assay showed that 5 μg/L of B[a]P promoted BEAS-2B cell invasion and migration. In addition, the mRNA and protein expression levels of AhR and its target genes involved in B[a]P metabolism, such as AhR nuclear translocator, heat shock protein 90 and CYP1A1, were significantly increased by B[a]P exposure. Moreover, the mRNA expression levels of downstream regulatory factors related to both AhR signaling pathway and EMT, such as NRF2, K-RAS and hypoxia-inducible factor 1-alpha, were significantly increased. Furthermore, the expression level of the epithelial marker E-cadherin was significantly downregulated, while the mRNA expression of mesenchymal phenotype markers, N-cadherin, fibronectin and vimentin, were significantly upregulated. Notably, the above changes induced by B[a]P were significantly attenuated or even stopped by resveratrol (RSV), a natural phenol, also an AhR inhibitor, when the AhR signaling pathway was inhibited by RSV, demonstrating the regulatory role of AhR signaling pathway in B[a]P-induced EMT. In conclusion, B[a]P at the human blood equivalent level induces BEAS-2B cell invasion and migration through the AhR signaling pathway. © 2020 John Wiley & Sons, Ltd.BACKGROUND Barley contains relatively high concentration of the mixed-linkage (1 → 3) (1 → 4) β-glucan, which has been reported as a functional food with prebiotic potential. In the current study, we compared the properties of two neutral barley β-glucans, obtained from raw barley (RBG) and Lactobacillus plantarum dy-1-fermented barley (FBG), respectively. RESULTS Molecular characteristics revealed that the molecular weight of barley β-glucan decreased from 1.13 × 105 D to 6.35 × 104 D after fermentation. Additionally, the fermentation improved the water/oil holding capacity, solubility, and swelling capacity of barley β-glucan. Both RBG and FBG significantly improved the locomotive behavior of nematodes, thereby increasing their energy consumption and reducing fat deposition, more significantly by FBG. In addition, these effects might be potentially dependent on nhr-49, TGF-daf-7 mediated pathways and so on, in which nhr-49 factor was particularly required. CONCLUSION These results suggested that fermentation may enhance in vitro physiological activities of barley β-glucan, thereby altering the effects on the lipid metabolism in vivo.

Recent unexpected findings, however, have defined novel and rather "uncommon" locations and activities of complement. Specifically, the discovery of an intracellularly active complement system-the complosome-and its key role in the regulation of cell metabolic pathways that underly normal human T cell responses have taught us that there is still much to be discovered about this system. Here, we summarize the current knowledge about the emerging functions of the complosome in T cell metabolism. We further place complosome activities among the non-canonical roles of other intracellular innate danger sensing systems and argue that a "location-centric" view of complement evolution could logically justify its close connection with the regulation of basic cell physiology. © 2020 John Wiley & Sons A/S.

STUDY DESIGN Ex vivo nested cohort study. SAMPLE POPULATION Commercially purchased fresh canine whole blood (n = 33 units). METHODS Commercially obtained canine whole blood was inoculated with known concentrations of one of three species of bacteria, Escherichia coli (ATCC 25922), Staphylococcus pseudintermedius (quality control strain; Texas A&M University), or Pseudomonas aeruginosa (ATCC 27853). Negative controls were inoculated with sterile saline. link2 The inoculated blood was processed through a cell salvage system and filtered through a series of two leukocyte reduction filters. Samples were aseptically collected at five points during processing (inoculum, prewash, postwash, post-first filtration, and post-second filtration) for bacterial enumeration. RESULTS Bacterial concentrations were reduced by 85.2%, 91.5%, and 93.9% for E coli, S pseudintermedius, and P aeruginosa, respectively, after washing (P  less then  .0001), and bacterial concentrations were reduced by 99.9%, 100%, and 100%, respectively, after the first filtration (P  less then  .0001). After the second filtration, none of the three species of bacteria could be isolated (100% reduction). No bacterial growth was obtained from negative controls throughout the study. The type of bacteria (P = .29) did not allow prediction of bacterial reduction. CONCLUSION Cell salvage washing combined with leukoreduction filtration eliminated bacterial contamination of whole dog blood (P  less then  .0001). CLINICAL SIGNIFICANCE Cell salvage washing and leukoreduction filtration could be applied to intraoperative autotransfusion in clinical animals, especially those treated for trauma or hemorrhage with concurrent bacterial contamination. https://www.selleckchem.com/products/od36.html'>https://www.selleckchem.com/products/od36.html'>https://www.selleckchem.com/products/od36.html'>https://www.selleckchem.com/products/od36.html © 2020 The American College of Veterinary Surgeons.Helminthiasis is one of the gravest problems worldwide. link2 There is a growing concern on less available anthelmintics and the emergence of resistance creating a major threat to human and livestock health resources. Novel and broad-spectrum anthelmintics are urgently needed. The free-living nematode Caenorhabditis elegans could address this issue through automated high-throughput technologies for the screening of large chemical libraries. This review discusses the strong advantages and limitations for using C elegans as a screening method for anthelmintic drug discovery. C elegans is the best model available for the validation of novel effective drugs in treating most, if not all, helminth infections, and for the elucidation the mode of action of anthelmintic candidates. This review also focuses on available technologies in the discovery of anthelmintics published over the last 15 years with particular attention to high-throughput technologies over conventional screens. https://www.selleckchem.com/products/od36.html'>https://www.selleckchem.com/products/od36.html'>https://www.selleckchem.com/products/od36.html'>https://www.selleckchem.com/products/od36.html On the other hand, this review highlights how combinatorial and nanomedicine strategies could prolong the use of anthelmintics and control resistance problems. © 2020 Wiley Periodicals, Inc.Capacity development has become embedded as part of the aid package offered by international organisations in response to humanitarian crises. link2 However, the effectiveness of such capacity development efforts is rarely monitored or examined. Further, the local context and learning preferences of trainees appear to be often overlooked. link3 link3 Globally, the informal construction sector is thriving hence, using a case study of Nepal, where construction and post-earthquake reconstruction efforts are largely delivered by the informal construction sector, this paper examines how and whether informal construction workers effectively develop capacity and utilise trainings to develop more disaster resilient buildings. This paper explores how learning preferences of Nepalese construction workers could be drawn on to improve the effectiveness and sustainability of capacity development efforts. Finally, this paper highlights that training programmes informed by the context and preferred learning style of disaster affected communities, promote and sustain capacity development efforts. link3 This article is protected by copyright.

Although it is considered to be an important micronutrient, it also is connected with several pathologies, including carcinogenicity. The mechanism of action of Cr and its compounds in humans is not yet fully understood. Currently, three possible mechanisms have been proposed for carcinogenesis Cr(VI)-induced multistage carcinogenesis, genomic instability, and epigenetic modification. Therefore, in addition to the toxicity of this metal and its ions, human susceptibility to Cr-induced pathologies depends on external factors and individual characteristics, such as enzymatic polymorphisms, carriers, endogenous reducing system, adduct formation and stability, and efficiency of DNA repair mechanisms, among other factors. In fact, the variability of individual molecular constitutive factors, such as individual polymorphisms, creates an individualized environment for Cr toxicity. This mini-review contemplates the essential variables in this process.
