Aflatoxin B-1 (AFB1) is one of the major mycotoxins causing food contamination. Previous studies have shown that AFB1 can induce carcinogenicity and toxic effects in the isolated perfused rat liver and these effects are associated with its metabolites and peroxidation activity. Here we surveyed whether these pathogenic effects of AFB1 are associated with TNF-α as an inflammatory cytokine in general liver damages. In this study, we used twenty male Wistar rats (250-300 g). Rats were divided into four groups...

The problems posed by fecal sludge (FS) are multidimensional because most cities rapidly urbanize, which results in the increase in population, urban settlement, and waste generation. Issues concerning health and waste treatment have continued to create alarming situations. These issues had indeed interfered with the proper steps in managing FS, which contaminates the environment. FS can be used in agriculture as fertilizer because it is an excellent source of nutrients. The recent decline in crop production due to loss of soil organic component, erosion, and nutrient runoff has generated interest in the recycling of FS into soil nutrients through stabilization and composting...

ETHNOPHARMACOLOGICAL RELEVANCE: Cedar is part of the phylum of conifers, and it´s essential oil has been used for therapeutic purposes since ancient times. In our previous study, we have demonstrated that the inhalation of the Cedrus atlantica essential oil (CaEO) induces an antihyperalgesic effect in a model of postoperative pain. But the mechanism that underlies this effect is not yet fully known. AIM OF THE STUDY: This study investigates the involvement of the endocannabinoid system in the antihyperalgesic effect produced by the inhalation of CaEO in a post operative pain model...

The enzymatic, ecofriendly pretreatment of wheat bran with α-amylase from Bacillus amyloliquifaciens or B. licheniformis at 90°C for 1.5h followed by Neutrase at 50°C for 4h, aqueous liquefaction at 121°C for 15h and ethanol precipitation enabled the production of soluble arabinoxylan (AX) with purity of 70.9% and 68.4% (w/w) respectively. Process alternatives tried, to simplify the process and curtail the cost resulted in AX products with different purities, yields and arabinose to xylose ratio (A/X). Among the two glycoside hydrolase (GH) family endoxylanases evaluated, GH10 family hydrolysed soluble AX more efficiently with xylanase from Geobacillus stearothermophilus T-6 (GsXyn10A) producing maximum amount of quantifiable short xylo-oligosaccharides (XOS) and arabinoxylo-oligosaccharides (AXOS) (53% w/w) followed by the catalytic module of Rhodothermus marinus Xyn10A (RmXyn10A-CM) with 37% (w/w) conversion...

Using a simple liquid-liquid extraction (LLE) procedure for sample pretreatment, 7-Aminoflunitrazepam (7-aminoFM2), a major metabolite of flunitrazepam (FM2), was determined in urine samples by polymeric monolith-based capillary liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). The linearity was found in the range of 0.1-50ngmL(-1) with a method detection limit (signal-to-noise ratio of 3) estimated at 0.05ngmL(-1). Using the proposed method, good precision and recovery were also found in spiked urine samples at the levels of 0...

β-Xylosidase activity is deficient in most cellulase enzymes secreted by filamentous fungi, which limits effective enzymatic hydrolysis of hemicellulose in lignocellulose materials and resulted in accumulation of xylo-oligosaccharides that inhibit the cellulase and xylanase activitives. An endogenous β-xylosidase gene, xyl3A, was overexpressed using two types of promoters in cellulolytic P. oxalicum RE-10. The mutants RXyl, RGXyl-1 and RGXyl-2 displayed higher β-xylosidase production than native strain RE-10 besides higher cellulase and xylanase activities, especially RGXyl-1, showing the highest β-xylosidase activity of 15...

The potential applications of low temperature plasma (LTP) in wound healing have aroused the concern of many researchers. In this study, an argon atmospheric pressure plasma jet was applied to generate LTP for treatment of murine fibroblast cell (L929) cultured in vitro to investigate the effect of NF-κB pathway on fibroblast proliferation. The results showed that, compared with the control, L929 cells treated with plasma for less than 20 s had significant increases of proliferation; the productions of intracellular ROS, O2(-) and NO increased with prolongation of LTP treatment time; NF-κB pathway was activated by LTP in a proper dose range, and the expression of cyclinD1 in LTP-treated cells increased with the same trend as cell proliferation...

Depression is a common mental disorder that affects millions of individuals worldwide. Available monoaminergic antidepressants are far from ideal since they show delayed onset of action and are ineffective in approximately 40% of patients, thus indicating the need of new and more effective drugs. ATP signaling through P2 receptors seems to play an important role in neurophatological mechanisms involved in depression, since their pharmacological or genetic inactivation induce antidepressant-like effects in the forced swimming test (FST)...

Earthworms contain several digestive and therapeutic enzymes that are beneficial to our health and useful for biomass utilization. Specifically, earthworms contain potent fibrinolytic enzymes called lumbrokinases, which are highly stable even at room temperature and remain active in dried earthworm powder. However, the high-temperature sterilization method leads to the inactivation of enzymes. Therefore, we investigated the effect of high-pressure treatment (HPT) (from 0.1 MPa to 500 MPa at 25°C and 50°C) on the enzymatic activity of lumbrokinase (LK), α-amylase (AMY), endoglucanase (EG), β-glucosidase (BGL), and lipase (LP) of the earthworm Eisenia fetida, Waki strain, and its sterilization ability in producing dietary supplement...

The over-the-counter antitussive dextromethorphan (DM) may have rapid antidepressant actions based on its overlapping pharmacology with ketamine, which has shown fast antidepressant effects but whose widespread use remains limited by problematic side effects. We have previously shown that DM produces antidepressant-like effects in the forced swim test (FST) and tail suspension test (TST) that are mediated in part through α-amino-3-hydroxy-5-methyl-4-isoxazole propionic (AMPA) and sigma-1 receptors, two protein targets associated with a faster onset of antidepressant efficacy...

Dextromethorphan (DM) is a dextrorotatory isomer of levorphanol, a typical morphine-like opioid. When administered at supra-antitussive doses, DM produces psychotoxic and neurotoxic effects in humans. Although DM abuse has been well-documented, few studies have examined the effects of high-dose DM. The present study aimed to explore the effects of a single high dose of DM on mortality and seizure occurrence. After intraperitoneal administration with a high dose of DM (80mg/kg), Sprague-Dawley rats showed increased seizure occurrence and intensity...
