Sepsis-induced discerning parvalbumin interneuron phenotype loss and psychological problems might be mediated simply by NADPH oxidase 2 activation inside rodents.
Interestingly, chronic stress accompanied by increased glucocorticoid levels and locus coeruleus activity and leading to mood disorders in which sleep disturbances are prevalent, also affects brain glycogen turnover via glucocorticoids, noradrenaline, serotonin and adenosine. These observations altogether suggest that inadequate astrocytic glycogen turnover may be one of the mechanisms linking migraine, mood disorders and sleep.There has been growing research interest in exploiting biochar for cost-effective. removal of different pollutants. Heavy metals, especially copper II (Cu II) is highly toxic and nonbiodegradable pollutants, and has been major source of environmental pollution. In this study adsorption of Cu (II) on seaweed (Ascophyllum nodosum)-derived biochar was systematically examined. The removal efficiency based on surface property of biochar and type of interactions associated with biochar produced at varying pyrolysis conditions were investigated. The highest removal efficiency of Cu (II) from aqueous media was >99% with 223 mg g-1 Cu (II) adsorption capacity observed by biochar derived at 700 °C and pH 5. Langmuir adsorption isotherm described the adsorption mechanisms of Cu (II) on biochar with cationic and anionic electrostatic attractions, surface precipitation, and pore depositions. Thus, this study shows that waste biomass (seaweed) could be a valuable bioresource for heavy metal remediation from various water bodies.The aim of this review to address the plant-associated bacteria to enhance the phytoremediation efficiency of the heavy metals from polluted sites and it is also highlighted advances for the application in wastewater treatment. Plant-associated bacteria have potential to encourage the plant growth and resistance under stress conditions. Such bacteria could enhance plant growth by controlling growth hormone, nutrition security, producing siderophore, secondary metabolites, and improving the antioxidant enzymes system. This review also explores the concepts and applications of bacteria assisted phytoremediation, addressing aspects that affect phytoremediation and pathways for restoration. Significant review issues relating to production and application of bacteria for improvement of bioremediation were established and presented for possible future research. Bacteria assisted phytoremediation is cost-effective strategy and metal sequestration mechanism that hold high metal biosorption capacities. This also takes into consideration the current state of technology implementations and proposals for prospective clean-up studies.High concentrations of pollutants in pig manure anaerobic digestate effluent (PMADE) can severely inhibit microalgal growth. In this study, two types of PMADE (PMADE-1, PMADE-2) were pretreated with indigenous bacteria which were selected from PMADE to alleviate their inhibition for the growth of Chlorella vulgaris. Indigenous bacteria could decrease 34.04% and 47.80% of total phosphorus (TP) and turbidity in PMADE-1, and 80.81%, 43.27%, and 57.51% of COD, TP, and turbidity in PMADE-2, respectively. And no significant reduction of NH4+-N in both PMADE after 5 days pretreatment occurred. learn more C. vulgaris failed to grow in unpretreated PMADE-2. Pretreatment of PMADE with indigenous bacteria could remarkably promote nutrients removal and cell growth of C. vulgaris compared to the unpretreated PMADE. The order of abiotic stress in the studied PMADE was COD > NH4+-N > turbidity, and it is appropriate to pretreat the PMADE with indigenous bacteria for 2-3 days.This study aimed to improve biomass, carotenoid, bacteriochlorophyll, protein, lipid, and carbohydrate contents of Rhodopseudomonas faecalis PA2 using different light regimes. Light intensity (4000, 6000, 8000, and 10,000 lx), together with photoperiod (240, 168, 1212, and 816 h light/dark), was assigned as single-phase (SP) cultivation while two-phase (TP) cultivation used two light intensities (using 4000 lx as the first phase), together with the control of phase shift (3, 6, and 9 days) and photoperiod. Biomass, carotenoid, and bacteriochlorophyll contents were maximized by SP cultivation; light at 8000 lx with light-dark cycle of 240 was optimal for pigments synthesis. In contrast, TP was useful to enhance storage compounds; protein, lipid, and carbohydrate productivities were significantly increased by 121.69%, 101.69%, and 92.44%, respectively, in TP when compared with SP. This indicates that the novel light strategy proposed in this study was able to manipulate the production of valuable substances in this strain.
Lysophosphatidylcholine Acyltransferase 1 (LPCAT1) is necessary for surfactant production in fetal lungs. Mechanisms responsible for its regulation during gestation remain to be elucidated. Our goal is to evaluate molecular mechanisms regulating LPCAT1 expression during gestation and after glucocorticoid administration.

Placentas throughout gestation were assayed for LPCAT1 protein levels. A placental cell line, HTR-8/SVneo (HTR), was used as a model to test the effects of placental oxygen tension found during pregnancy as well as the effects of dexamethasone used therapeutically in the clinic.

LPCAT1 protein levels are maximal in late third trimester placental samples and are expressed strongly on the basal plate. LPCAT1 was maximally upregulated at 4% O
(P<0.01), corresponding to oxygen tension found in placenta at term. Mitochondrial nuclear retrograde regulator 1 (MNRR1), a bi-organellar (mitochondria and nucleus) regulator, transcriptionally activates LPCAT1. Antenatal corticosteroids (ACS) upregulate LPCAT1, at least in part, by an MNRR1-dependent pathway. HTR cells treated with 25nM dexamethasone for 24h exhibited a 2-fold increase in LPCAT1 levels compared to controls. In MNRR1 knockout cells, the response to ACS is significantly blunted.

LPCAT1 appears to be induced by MNRR1. Hypoxia and corticosteroids increase LPCAT1 expression through an MNRR1 dependent pathway. LPCAT1 protein levels can be measured in maternal plasma and rise throughout gestation and in response to ACS.
