There has been a surge of interest over the past several years in the use of neurochemical endpoints to contribute to our understanding of the mechanism of action of neurotoxicants. In our present presentation, two biogenic amine systems were selected as examples of biomarkers for neurotoxicity. To investigate these neurochemical endpoints, two prototype neurotoxicants were evaluated in experimental animals. One agent, reserpine, was used to assess developmental neurotoxicity and administered prenatally, while the other, MDMA, was used in the adult animal. The neurochemical biomarkers measured were dopamine, serotonin, and their metabolite (DOPAC and 5-HIAA) concentrations by HPLC/EC and dopamine receptor binding by radioligand receptor techniques. A review of the background, experimental design, and results are presented in this article. Our findings indicate that components of the biogenic amine systems can be used as sensitive neurochemical biomarkers of neurotoxicity. These neurochemical biomarkers can be correlated with neuropathological and behavioral biomarkers to aid in the understanding of mechanisms of neurotoxicity.

The existence of pulsating stars in eclipsing binaries has been known for decades. These types of objects are extremely valuable systems for astronomical studies as they exhibit both eclipse and pulsation variations. The eclipsing binaries are the only way to directly measure the mass and radius of stars with a good accuracy(≤1%),while the pulsations are a unique way to probe the stellar interior via oscillation frequencies. There are different types of pulsating stars existing in eclipsing binaries. One of them is the δ Scuti variables. Currently, the known number of δ Scuti stars in eclipsing binaries is around 90 according to the latest catalog of these variables. An increasing number of these kinds of variables is important to understand the stellar structure, evolution and the effect of binarity on the pulsations. Therefore, in this study, we focus on discovering new eclipsing binaries with δ Scuti component(s). We searched within the northern Transiting Exoplanet Survey Satellite(TESS) field with a visual inspection by following some criteria such as light curve shape, the existence of pulsation like variations in the out-of-eclipse light curve and the Teffvalues of the targets. As a result of these criteria, we discovered some targets. The orbital variations were first removed from the TESS light curves and frequency analysis was performed on the residuals. The luminosity, and absolute and bolometric magnitudes of the targets were calculated as well. To find how much of these parameters represent the primary(more luminous) binary component, we also computed the flux density ratio of the systems by utilizing the area of the eclipses. In addition, the positions of the systems in the H-R diagram were examined considering the flux density ratios. As a consequence of the investigation, we defined 38 candidate δ Scuti stars and also one Maia variable in eclipsing binary systems.

To improve the phosphorus(P)recovery efficiency from livestock wastewater,a novel MgO doped mildewed corn biochar with thermal pre-puffing treatment(Mg-PBC)and without pre-puffing(Mg-BC)was synthesized and *** thermal-puffing pretreatment improved the effectiveness of metal soaking and MgO dispersion.P recovery time with Mg-PBC(7 h)was significantly shorter than that with Mg-BC(12 h).Moreover,Mg-PBC showed significantly higher P recovery capacity(241 mg g^(−1))than Mg-BC(96.6 mg g^(−1)).P recovery capacity of the Mg-PBC fitted to the Thomas model was 90.7 mg g^(−1),which was 4 times higher than that of Mg-BC(22.9 mg g^(−1))under column test *** mechanisms involved in P recovery included precipitation,surface complexation,and electrostatic *** adsorption,both Mg-BC and Mg-PBC showed relatively low regeneration *** P loaded Mg-BC(Mg-BC-P)and Mg-PBC(Mg-PBC-P),the later particularly,obviously increased the available P content and promoted plant *** release of P increased with time in the Mg-PBC-P treated soil,while it decreased with time in the P fertilizer treated soil.A cost-benefit analysis revealed that thermal-puffing pretreatment greatly increased the profit of MgO doped biochar from−0.66 to 5.90 US$kg^(−1).These findings highlight that biomass pre-puffing is a feasible treatment to produce MgO modified biochar and to recover P from livestock wastewater,and that the Mg-PBC-P can be used as a slow-release P fertilizer.
