The plant MBF1 protein family: a bridge between stress and transcription
(Oxford University Press, 2020)"The Multiprotein Bridging Factor 1 (MBF1) proteins are transcription co-factors whose molecular function is to form a bridge between transcription factors and the basal machinery of transcription. MBF1s are present in ... -
Heterojunction of CuO nanoclusters with TiO2 for photo-oxidation of organic compounds and for hydrogen production
(American Institute of Physics, 2020)"Heterojunctions of small CuO nanoclusters (synthesized by radiolysis) with TiO2 (commercial P25) induced a photocatalytic activity under visible light irradiation in a wide range of wavelengths due to the narrow bandgap ... -
Phase transformation and magnetocaloric effect of Co-doped Mn–Ni–In melt-spun ribbons
(American Institute of Physics, 2020)"Ribbon-shaped magnetocaloric materials are favorable to achieve high heat-transfer efficiencies due to their large specific surface area. In this work, Mn50Ni41−xIn9Cox (0 ≤ x ≤ 4) ribbons were prepared using a melt-spinning ... -
Removal of Cu, Cd, Pb and Zn from Contaminated Soil by Using Plant-Based Surfactants, Sapindus mukorossi L (Soapnut) and Acacia Concinna (Shikakai)
(IJESD, 2019)"The performance of two plant-based surfactants in the removal of heavy metals (Cu, Cd, Pb and Zn) from soil was studied ex-situ. Experimental parameters were: six soil-solution ratios (1:10, 1:20, 1:30, 1:40, 1:50 and ... -
Temporal analysis of butterfly diversity in a succession gradient in a fragmented tropical landscape of Mexico
(Elsevier, 2020)"We analyze changes in the diversity of butterflies under a scheme of secondary succession in a fragmented landscape of the Huasteca of Hidalgo, Mexico over two seasons (rainy and dry) and four successional stages (cattle ... -
Bacterial Diversity and Interaction Networks of Agave lechuguilla Rhizosphere Differ Significantly From Bulk Soil in the Oligotrophic Basin of Cuatro Cienegas
(Frontiers Media S.A., 2020)"Due to the environmental conditions presented in arid zones, it is expected to have a high influence of deterministic processes over the community assemblages. Symbiotic interactions with microorganisms could increase ... -
Antioxidant activity of a new multiflorane-type triterpene from seeds of Cucurbita Argyrosperma and their protective role on hydrogen peroxide induced oxidative stress
(Functional Food Center Inc., 2020)"Background: Cucurbita Argyrosperma seeds have acquired a reputation as an herbal remedy to treat various diseases because this plant is a predominant source of natural compounds with potent anti-inflammatory, antioxidant ... -
Chemoresistance in Breast Cancer Patients Associated With Changes in P2X7 and A2A Purinergic Receptors in CD8+ T Lymphocytes
(Frontiers Media S.A., 2020)"Breast cancer (BRCA) is the most frequent cancer type that afflicts women. Unfortunately, despite all the current therapeutic strategies, many patients develop chemoresistance hampering the efficacy of treatment. Hence, ... -
Humic Substances Mediate Anaerobic Methane Oxidation Linked to Nitrous Oxide Reduction in Wetland Sediments
