Inhibition of histone deacetylases is the major pathway mediated by astaxanthin to antagonize LPS-induced inflammatory responses in mammary epithelial cells.Mastitis is a major inflammatory response of the mammary gland due to various pathogenic invasions and is a serious disease that affects the production yield and health status of cows. Astaxanthin (AST), a xanthophyll carotenoid, is a secondary metabolite synthesized by microalgae and yeasts that has been reported to suppress various inflammatory responses. However, the protective effect of AST on lipopolysaccharide (LPS)-induced mammary epithelial cells has not yet been reported. The present study results indicated that AST treatment markedly attenuated the oxidative stress markers and nitric oxide (NO) while improving the anti-oxidant enzymes in LPS exposed cells. On the other hand, LPS-exposed cells showed nuclear translocation of nuclear factor-κB (NF-κB) with the activation of inflammatory cytokines such as monocyte chemoattractant protein-1, tumor necrosis factor-α, interferon-γ, and interleukin-6 (IL-6). In addition, mRNA expression analysis revealed that the histone deacetylase (HDAC) -1, -2, -3, -6, -7 and pentraxin 3 (PTX3) expressions were increased in the LPS group. Furthermore, the activity of HDAC was increased to 2-fold with a significant reduction in the histone acetyltransferase activity in cells exposed to LPS. However, AST was able to inhibit the nuclear translocation of NF-κB with attenuated HDAC activity. Intriguingly, HDAC inhibition studies demonstrated that the cytokines such as IL-4, IL-8, granulocyte-mcrophage colony stimulating factor, C-reactive protein, IL-17A, and IL-22 were significantly suppressed which were upregulated in LPS treatment; while AST was found acting by improving the anti-inflammatory cytokine IL-10, and thioredoxin reductase levels. Collectively, these findings provide novel insights into the role of HDACs in regulating cellular processes involved in the pathogenesis of LPS-induced mastitis as well as the potential use of AST as a therapeutic in treatment for controlling disease progression.

Grip on Life as a possible antecedent for self-control beliefs interacts with well-being and perceived stress.Self-control has been established as an important factor in various domains of life, significant for general well-being; thus, a self-induced lack of self-control may prove detrimental for well-being. Self-induced lack of self-control may stem from implicit beliefs about self-control as a limited resource, but research has shown this belief to be unwarranted. Furthermore, it has been shown that a belief about self-control resources as unlimited has a positive effect on many domains in life and ultimately on well-being. This study addresses the question of antecedent beliefs about self-control resources and proposes personal Grip on Life, defined as skill-based goal setting and goal approaches, as a possible antecedent. This points to development of interventions altering a limited belief to an unlimited belief based on empowerment of one's Grip on Life.

Modification and utility of a rat burn wound model.This study aimed to improve the conventional rat burn wound model and to validate its utility. In total, 60 Sprague-Dawley rats were divided equally into the control and experimental groups. Altogether, 60 burn wound models with zones of stasis were created in each group. Gross visual assessments of the burn wounds were performed at 0 h, 24 h, and 48 h after burn creation. The rates of necrosis in the zones of stasis were calculated, and the blood flow from the wounds was examined. Wound tissues were collected 48 h after the burn and subjected to hematoxylin and eosin staining to determine whether the models were successfully established. The model success rates were calculated. The success rate of the burn wound models was significantly different between the control group and the experimental group (93.33% [56/60] vs. 100%; P=0.042). The Cronbach's alpha values and the respective correlation coefficients indicated that the stability of the zones of stasis in the models on the 2 sides of the spine was higher in the experimental group than in the control group. The standard deviations of the rate of necrosis, blood flow, and density of necrotic cells and apoptosis cell density, and inflammatory factor content in the zones of stasis were smaller in the experimental group than in the control group at 48 h after model construction. This suggested that the stability of repeated procedures was higher in the experimental group than in the control group. The novel device for creating burns in animal models facilitated the effective creation of zones of stasis for rat burn wound models. Both the model success rate and stability were higher compared with the conventional model construction method. In addition, the use of the novel device can better align with the requirements of self-controlled studies. This article is protected by copyright. All rights reserved.

Irisin ameliorates high glucose-induced cardiomyocytes injury via AMPK/mTOR signal pathway.High glucose (HG)-induced cardiomyocytes (CMs) injury is a leading cause of diabetic cardiomyopathy with little treatment options. Irisin, a new myokine, which is cleaved from its precursor fibronectin type III domain-containing protein 5 (FNDC5), has aroused great attentions as an essential cardioprotective factor and glucose metabolism regulator but little was known on diabetic cardiomyopathy yet. Here, we aim to clarify the role of irisin in the HG-induced CMs injury. Neonatal Sprague-Dawley (SD) rat CMs were cultured in a normal or high glucose medium for 12, 24 and 48 h respectively before exposing to irisin. The apoptosis level was determined by Terminal-deoxynucleotidyl transferase mediated-dUTP Nick End Labeling (TUNEL) assay. Cell viability was measured with the conventional methylthiazolyl tetrazolium (MTT) assay. Moreover, reactive oxygen species (ROS) production was evaluated by dihydroethidium (DHE) staining. Inflammatory factors, namely TNF-ɑ, IL-6, IL-1β were determined by enzyme-linked immunosorbent assay (ELISA) kits. Furthermore, protein and mRNA expressions were measured by Western blot and qRT-PCR respectively. HG increases the apoptosis of CMs and activated the inflammatory responses and oxidative stress in CMs. Meanwhile, the mRNA and protein expressions of FNDC5 are decreased after HG exposure. Nevertheless, the increased apoptosis is alleviated by irisin treatment. Notably, irisn suppresses the inflammatory responses and oxidative stress in injured CMs. Mechanically, after administration of Compound C, AMPK inhibitor, these cardioprotective effects resulting from irisin are reversed. Irisin plays a significant role in anti-apoptosis, anti-inflammation, anti-oxidative stress in HG-induced CMs via AMPK/mTOR signaling pathway. This article is protected by copyright.

Ion Homeostasis for Salinity Tolerance in Plants: A Molecular Approach.Soil salinity is one of the major environmental stresses faced by the plants. Sodium chloride is the most important salt responsible for inducing salt stress by disrupting the osmotic potential. Due to various innate mechanisms, plants adapt to the sodic niche around them. Genes and transcription factors regulating ion transport and exclusion like Salt Overly Sensitive (SOS), Na /H Exchangers (NHXs), High Sodium Affinity Transporter (HKT) and Plasma membrane protein (PMP) are activated during salinity stress and help in alleviating cells of ion toxicity. For salt tolerance in plants signal transduction and gene expression is regulated via transcription factors such as NAM (no apical meristem), ATAF (Arabidopsis transcription activation factor), CUC (cup-shaped cotyledon), Apetala 2/Ethylene Responsive Factor (AP2/ERF), W-box binding factor (WRKY) and Basic Leucine Zipper Domain (bZIP).Crosstalk between all these transcription factors and genes aid in developing the tolerance mechanisms adopted by plants against salt stress. These genes and transcription factors regulate the movement of ions out of the cells by opening various membrane ion channels. Mutants or knockouts of all these genes are known to be less salt-tolerant compared to wild types. Using novel molecular techniques like analysis of genome, transcriptome, ionome and metabolome of a plant, can help in expanding the understanding of salt tolerance mechanism in plants. In this review, we discuss the genes responsible for imparting salt tolerance under salinity stress through transport dynamics of ion balance and need to integrate high-throughput molecular biology techniques to delineate the issue.
