A2A R inhibition in alleviating spatial recognition memory impairment after TBI is associated with improvement in autophagic flux in RSC.
Abstract Spatial recognition memory impairment is an important complication after traumatic brain injury (TBI). We previously found that spatial recognition memory impairment can be alleviated in adenosine A2A receptor knockout (A2A R KO) mice after TBI, but the mechanism remains unclear. In the current study, we used manganese-enhanced magnetic resonance imaging and the Y-maze test to determine whether the electrical activity of neurons in the retrosplenial cortex (RSC) was reduced and spatial recognition memory was impaired in wild-type (WT) mice after moderate TBI. Furthermore, spatial recognition memory was da...

Method validation for a multi-element panel in serum by inductively coupled plasma mass spectrometry (ICP-MS).
Abstract BACKGROUND: Laboratory testing for trace and toxic elements is important to diagnose metal toxicity and nutritional deficiency. There are several essential elements that are necessary for biological function and non-essential elements that can pose risk from exposure. Both essential and nonessential elements can be toxic if concentrations exceed a certain threshold. METHODS: An aliquot of serum was diluted in a diluent solution, which contained iridium (Ir) as the internal standard, gold (Au), 0.05% Triton X-100, and 1% nitric acid (HNO3). The diluted specimen was aspirated into an inductively couple...

Mitoxantrone as photothermal agents for ultrasound/fluorescence imaging-guided chemo-phototherapy enhanced by intratumoral H2O2-Induced CO.
Abstract Multimodal imaging integrated theranostic nanomaterials provides broad prospects for noninvasive and precise cancer treatment. However, the uncertain physiological metabolism of the existing phototherapy nanoagents greatly prevents its clinical application. Herein, a smart nanoplatform based on clinically chemotherapeutic drugs mitoxantrone (MTO) was prepared to realize ultrasound/fluorescence imaging-guided chemo-photothermal combined therapy. The nanoplatform encapsulating MTO and manganese carbonyl (MnCO), which denoted as MCMA NPs, could accumulate at tumor sites by enhanced permeability and retention...

Synergistic effect of modified Pd-based cobalt chromite and manganese oxide system towards NO-CO redox detoxification reaction.
Abstract Surface architecting of the catalyst is a hopeful method to expand the surface property of the impetus material for upgrading their response towards the chemical reaction. In the present study, designing of the catalyst was carried out using specific transition metals to boost the simultaneous NO-CO conversion reaction catalytically. These metal oxide systems have been prepared using the combustion and wet impregnation method. Prepared oxides were characterized using XRD, BET, XPS, SEM, and TEM. Further, the surface phenomenon of the catalyst was monitored through H2-TPR, O2-TPO, NO-TPD, and CO-TPD studie...

Brain manganese and the balance between essential roles and neurotoxicity [Molecular Bases of Disease]
Manganese (Mn) is an essential micronutrient required for the normal development of many organs, including the brain. Although its roles as a cofactor in several enzymes and in maintaining optimal physiology are well-known, the overall biological functions of Mn are rather poorly understood. Alterations in body Mn status are associated with altered neuronal physiology and cognition in humans, and either overexposure or (more rarely) insufficiency can cause neurological dysfunction. The resultant balancing act can be viewed as a hormetic U-shaped relationship for biological Mn status and optimal brain health, with changes i...

Improving Azo Dye Decolorization Performance and Halotolerance of Pichia occidentalis A2 by Static Magnetic Field and Possible Mechanisms Through Comparative Transcriptome Analysis
A halotolerant yeast, Pichia occidentalis A2, was recently isolated that can decolorize various azo dyes. The azo dye decolorization performance of this strain was characterized, including the degradation pathway and detoxification effects of this yeast. Additionally, the effect of static magnetic field (SMF) on this decolorization process was investigated. Activities of key enzymes were analyzed to estimate the change of metabolic activity. Furthermore, possible mechanisms were analyzed through detecting differentially expressed genes between yeast A2 in the absence and presence of SMF. The results indicated that yeast A2...

Co-exposure to multiple metals, TERT-CLPTM1L variants, and their joint influence on leukocyte telomere length.
CONCLUSIONS: Our study revealed the independent and positive association between plasma Mn and LTL when accounting for co-exposure to other metals. This effect can be further enhanced by TERT-CLPTM1L variants. These results may advance our understanding of the complex interplay between genetic and environmental factors on telomere length. Further experimental studies are warranted to elucidate the underlying mechanisms. PMID: 32380304 [PubMed - as supplied by publisher] (Source: Environment International)

Ecological risk assessment of heavy metals to aquatic organisms in the Lhasa River, Tibet, China.
Abstract The Lhasa River is the largest and most important tributary of the Yarlung Tsangpo River on the Tibetan Plateau, China. It is an important source of drinking water and irrigation for the inhabitants living in the watershed. Despite the increasing focus on water chemistry, the ecological risk assessment (ERA) caused by heavy metals to aquatic organisms in the Lhasa River has not been performed before. Based on the documented monitoring data for heavy metals, the species sensitivity distributions (SSDs) method was applied in this study. The potential ecological risks induced by eight major heavy metals (inc...
