Sustainable, clean, renewable energy without negotiating contiguous environment is a challenging task mainly comprises of natural resource management which involves operational efficiency, waste minimisation and energy recovery. Disposal of untreated industrial wastewater with chemical nutrients especially compounds containing nitrogen and phosphorous lead to eutrophication and related environmental issues that affect the recycling processes of bio system. Biotransformation of pollutants using microalgae has proven to be proficient and economic method of wastewater treatment due to their adaptability of growing in various wastewater streams and also useful in the process of CO2 fixation. Moreover this technology has the competence of producing bio fuels as an alternative energy resource in the form of bio diesel, bio ethanol and biogas. In this review paper, the applicability of microalgae cultivation in industrial wastewater treatment has been discussed extensively including the processes involved, influencing operational parameters such as study mode, cultivation mode and time, method of aeration, pH and intensity of light. Further, the cultivation methods, harvesting techniques involved in the treatment process have been presented. In addition, the analysis on removal efficiency of algal treatment, biomass productivity and lipid content of the cultivated biomass has been discussed widely which possibly will be helpful in adopting the process integration in industrial wastewater treatment with bio energy production. 相似文献

The hfe-threatening infections caused by Leptospira serovars demand the need for designing anti-leptospirosis drugs.The present study encompasses exploring inhibitors against phosphoheptose isomerase(GmhA)of Leptospira,which is vital for lipopolysaccharide(LPS)biosynthesis and is identified as a common drug target through the subtractive genomic approach.GmhA model was built in Modeller 9v7.Structural refinement and energy minimization of the predicted model was carried out using Maestro 9.0.The refined model reliability was assessed through Procheck,ProSA,ProQ and Profile 3D.The substrate-based virtual high-throughput screening(VHTS)in Ligand.Info Meta-Database tool generated an in-house library of 354 substrate structural analogs.Furthermore,structure-based VHTS from the in-house library with different conformations of each ligand provided 14 novel competitive inhibitors.The model together with insight gained from the VHTS would be a promising starting point for developing anti-leptospirosis competitive inhibitors targeting LPS biosynthesis pathway. 相似文献

Gastrodia elata blume (tianma) is a traditional Chinese herb often used in the treatment of convulsions, headaches, and hypertension. Although interest in neuronal-related actions of tianma is increasing, minimal studies have been conducted to determine its specific effects on neuronal cells. This study was designed to examine the effects of tianma on the metabolism in differentiated neuroblastoma cells using the isobaric tag for relative and absolute quantitation (iTRAQ) technology. Stimulation of these cells with tianma caused changes in the expression of 38 proteins that were subsequently classified according to their physiological functions and association with neurodegenerative diseases. We identified six proteins with altered functional activities in neurodegenerative disease states that were modulated by tianma: triosephosphate isomerase (Tpi1), peptidyl-prolyl cis-trans isomerase A (Ppia), neural cell adhesion molecule 1 (Ncam1), ubiquitin carboxyl-terminal hydrolase isozyme L1 (Uchl1), septin-2 (Sept2) and heat shock protein 90 (Hsp90aa1). We postulate that tianma mediates its neuroprotective effects via upregulation of Ncam1, Hsp90aa1, Tpi1 and Ppia while downregulating Sept2 and Uchl1. These changes in protein expression aid in the restoration of the intracellular environment to a metabolically balanced state, promoting cell survival. Based on these observed data, we conclude that tianma has therapeutic potential, especially for neurodegenerative diseases. 相似文献

Administration of a high dose of glucose (2.5 g/kg, i.p.) that is known to produce severe hyperglycemia in euglycemic rats suppressed rapid eye movement (REM) sleep time significantly during the first three hours of 8 hr total electroencephalogram (EEG) recording period. Co-administration of glucose (2.5 g/kg, i.p.) and a non-convulsive dose of insulin (1.0 I.U./kg, i.p.) produced a significant reduction in REM sleep time during 1st through 5th hour and an increase in slow-wave sleep (NREM) time in the 3rd and 4th hour of 8 hr total EEG recording period. However, awake, NREM and REM sleep time in the 8 hr total EEG recording period were unaffected by either glucose alone or glucose plus insulin treatments. These results strongly suggest that the insulin's effects on the sleep-awake cycle i.e. reduction in REM and a slight increase in NREM sleep times of rats is not due to indirect effects of insulin on the central nervous system via hypoglycemia as reported by us previously, but could possibly be due to its direct effects on brain chemistry of neurotransmitters such as serotonin, catecholamines and acetylcholine which are believed to modulate the sleep-awake cycle pattern in rats. 相似文献

Subcutaneous administration of naloxone at 1 to 10 mg/kg produced a dose-related decrease in feed intake of broiler chicks. Food deprivation for 3, 6, 12, and 24 hours produced a significant increase in feed intake compared to non-food deprived birds. Subcutaneous administration of naloxone at 1 to 10 mg/kg failed to attenuate hyperphagia of broiler chicks, deprived of food for 12 hrs. These data suggest that opiate receptors are involved in the regulation of spontaneous feeding behavior in broiler chicks. However, in contrast to other mammals and pigeons, a mechanism, other than endorphinergic system, not sensitive to naloxone blockade, might be involved in food deprivation induced hyperphagia in broiler chicks. 相似文献

Tianma (Rhizoma gastrodiae) is the dried rhizome of the plant Gastrodia elata Blume (Orchidaceae family). As a medicinal herb in traditional Chinese medicine (TCM) its functions are to control convulsions, pain, headache, dizziness, vertigo, seizure, epilepsy and others. In addition, tianma is frequently used for the treatment of neurodegenerative disorders though the mechanism of action is widely unknown. Accordingly, this study was designed to examine the effects of tianma on the proteome metabolism in differentiated human neuronal SH-SY5Y cells to explore its specific effects on neuronal signaling pathways. Using an iTRAQ (isobaric tags for relative and absolute quantitation)-based proteomics research approach, we identified 2390 modulated proteins, out of which 406 were found to be altered by tianma in differentiated human neuronal SH-SY5Y cells. Based on the observed data, we hypothesize that tianma promotes neuro-regenerative signaling cascades by controlling chaperone/proteasomal degradation pathways (e.g. CALR, FKBP3/4, HSP70/90) and mobilizing neuro-protective genes (such as AIP5) as well as modulating other proteins (RTN1/4, NCAM, PACSIN2, and PDLIM1/5) with various regenerative modalities and capacities related to neuro-synaptic plasticity. 相似文献
