Fresh data from hyperspectral imaging investigation on the effect of photobiomodulation therapy in normal epidermis oxygenation.
3% and 43.1% of the in utero accreted ARA and DHA. DHM had the highest proportion of lipid peroxidation. CONCLUSIONS This study confirms that DHM in the United Kingdom has insufficient LCPUFAs for preterm infants. It demonstrates for the first time that DHM has the highest level of lipid peroxidation, compared with preterm or term milk. This has important implications for preterm infant nutrition, as exclusive DHM feeding might not be suitable long term and may contribute to the development of major preterm neonatal morbidities. © 2020 American Society for Parenteral and Enteral Nutrition.Chlorpyrifos is a poisonous pesticide that is highly toxic to fish and aquatic organisms. However, there are fewer reports about how chlorpyrifos influences the redox balance of immune cells. Herein, the head kidney tissue treated with chlorpyrifos to do transcriptome analysis and TCR γ was screened out. Subsequently, we established TCR γ knockdown and overexpression carp head kidney lymphocyte models, respectively, by using RNA interference and pcDNA3.1. Real-time PCR, fluorescent staining, oxidation and antioxidant kit were used to detect the related factors. We found that TCR γ knockdown significantly increased the mRNA expression of HSP70 and HSP90 and decreased the mRNA expression of SOD and CAT. Meanwhile, TCR γ knockdown reduced the activities of GSH, GSG-PX, T-AOC, CAT and SOD and increased the content of MDA and H2 O2 and activities of iNOS. Adverse results were obtained in TCR γ overexpression group. Additionally, TCR γ knockdown significantly increased the mRNA expression of IFN-γ, IL-1β, IL-8, IL-10, Nrf2 and NF-κB, but relieved TCR γ overexpression, in which the process of inflammation was activated. Our results reported here indicated that chlorpyrifos induces redox imbalance-dependent inflammation in common carp lymphocyte through dysfunction of T-cell receptor γ, and HSPs play potential protective role in entire process. © 2020 John Wiley & Sons Ltd.White spot syndrome virus has been a threat to the global shrimp industry since it was discovered in Taiwan in 1992. Thus, shrimp-producing countries have launched regulations to prevent import of WSSV-infected commodity shrimp from endemic areas. Recently, cooked shrimp that is infected with WSSV tested positive by PCR. However, there is no study to determine the infectivity of WSSV in cooked shrimp that tested positive by PCR. In the present study, WSSV-infected shrimp were cooked at boiling temperature for different times including 0, 1, 3, 5, 10 and 30 min. Upon exposure to boiling temperature, WSSV-infected shrimp were fed to SPF shrimp (Litopenaeus vannamei). The result showed experimentally challenged shrimp from 0-min treatment (positive control) indeed got infected with WSSV. However, experimentally challenged shrimp that were fed tissues boiled at 1, 3, 5, 10 and 30 min were not infected with WSSV. Mortality data showed that only the positive control (0-min) treatment displayed high mortality, whereas no mortality was observed in any other treatment category. These findings suggest that cooking shrimp at boiling temperature for at least 1 min might prevent any potential spread of WSSV from endemic countries to other geographical areas where WSSV has not yet been reported. © 2020 John Wiley & Sons Ltd.BACKGROUND There is scarce information detailing clinical and physiological effects of reversible injectable protocols of chemical restraint on Neotropical primates. METHODS Nineteen captive Spix´s Owl monkeys (Aotus vociferans) were assessed in a double-blind randomized crossover study using the following ketamine/xylazine [KX], ketamine/midazolam [KM] and ketamine/xylazine/midazolam [KXM]. During immobilization, respiratory and pulse rates, rectal temperature, haemoglobin oxygen saturation and arterial blood pressure were recorded at 5-minute intervals during a 20-minute period; afterwards, antagonist drugs (yohimbine for xylazine and flumazenil for midazolam) were, respectively, administered. Quality and duration of induction, immobilization and recovery periods were recorded. RESULTS Ketamine/xylazine increased manipulation sensitivity and produced poor muscle relaxation. KM maintained all assessed parameters within physiological ranges. KXM produced depressant cardiorespiratory effects and hypotension. All protocols produced hypothermia. CONCLUSIONS Based on its adequate anaesthetic depth and minimum effects on physiological parameters, KM is suitable for immobilizing A vociferans and performing short-term procedures lasting around 20 minutes.

Published by John Wiley & Sons Ltd.Imbalance of T helper 17 (Th17)/regulatory T (Treg) cells is involved in the pathogenesis of myasthenia gravis with thymoma (MG-T). Long non-coding RNAs (lncRNAs) are implicated in the regulation of Th17/Treg balance. This study was designed to explore the role of XLOC_003810, a novel lncRNA, in regulating the Th17/Treg balance in MG-T. The thymic CD4+ T cells were isolated from control subjects and MG-T patients. The Th17/Treg balance was evaluated by determining proportions of Th17 and Treg cells and expression of Th17- and Treg- associated molecules. Lentivirus-mediated silencing and overexpression of XLOC_003810 in CD4+ T cells were performed. The results showed that XLOC_003810 expression was higher in MG-T thymic CD4+ T cells than that in the control group. Furthermore, the ratio of Th17/Treg cells, proportion of Th17 cells and levels of Th17-associated molecules were significantly increased, whereas the proportion of Treg cells and levels of Treg-associated molecules were decreased in MG-T thymic CD4+ T cells. Importantly, the Th17/Treg imbalance in MG-T thymic CD4+ T cells was aggravated by XLOC_003810 overexpression, whereas it was attenuated by XLOC_003810 silencing. Collectively, XLOC_003810 modulates thymic Th17/Treg balance in MG-T patients, providing the scientific basis for the clinical targeted therapy of MG-T. © 2020 John Wiley & Sons Australia, Ltd.γδ T cells play important roles in the development of rheumatoid arthritis (RA) through their antigen-presenting capacity, release of pro-inflammatory cytokines, immunomodulatory properties, interaction with CD4+ CD25+ Tregs and promotion of antibody production by helping B cells. Although prostaglandin E2 (PGE2) was proved to have the ability to enhance the antigen-presenting function of dendritic cells and IL-17 production of CD4+ αβ T cells in RA, the role of PGE2 in γδ T cells from RA disease has not yet been clarified. The goal of this study was to determine the role of PGE2 in γδ T cells in RA. We first demonstrated that the population of γδT17 cells increased in patients with RA compared to healthy controls. Then, IL-17A level in patients with RA was shown to increase compared to healthy controls. After adding PGE2 to γδ T cells from patients with RA, the IL-17A level increased accordingly, and the expression of the costimulatory molecules, CD80 and CD86, on these cells also increased. These results suggest that PEG2 can increase the production of IL-17A and the expression of CD80 and CD86 on γδ T cells in patients with RA.
