(Sociedad Botánica de México, 2022)"Background: Populus luziarum and P. primaveralepensis are endemic species of western Mexico; growing in riparian forests they are critically endangered. The best way to conserve their seeds is unknown, which could be ... -
Facile synthesis of a TiO2-Al2O3-GnPs compound and its application in the photocatalytic degradation of Diuron
(Elsevier, 2022)"New ternary materials TiO2-Al2O3-GnPs (TAG) were prepared by using an innocuous sol-gel method with a slight modification for the addition of graphene nanoplatelets (GnPs), under room temperature and atmospheric pressure. ... -
Physiological ecology of Mexican CAM plants: history, progress, and opportunities
(Sociedad Botánica de México, 2022)"In Mexico, plants with crassulacean acid metabolism (CAM) are part of the Mexican culture, have different uses and are even emblematic. Unfortunately, only a small fraction of the Mexican CAM plants has been studied ... -
Environmental Nanoparticles Reach Human Fetal Brains
(MDPI, 2022)"Anthropogenic ultrafine particulate matter (UFPM) and industrial and natural nanoparticles (NPs) are ubiquitous. Normal term, preeclamptic, and postconceptional weeks(PCW) 8–15 human placentas and brains from polluted ... -
Lactic acid fermentation of food waste at acidic conditions in a semicontinuous system: effect of HRT and OLR changes
(Springer Nature, 2022)"Lactic acid production through fermentation is an established technology, however, improvements are necessary to reduce the process costs and to decrease its market price. Lactic acid is used in many industrial sectors ... -
What is a biocrust? A refined, contemporary definition for a broadening research community
(Wiley, 2022)"Studies of biological soil crusts (biocrusts) have proliferated over the last few decades. The biocrust literature has broadened, with more studies assessing and describing the function of a variety of biocrust communities ... -
Why Nose and Mouth Coverings are Highly Recommended to Impede SARS-Cov-2 Spread
(Walsh Medical Media, 2021)"In fourteen months the number of infected people with SARS-COV-2 has reached more than 159 millions and from those more than 3 million have resulted in death. There is now a consensus that the airborne saliva droplets, ... -
Landscape attributes shape dung beetle diversity at multiple spatial scales in agricultural drylands
(Elsevier, 2022)"Land-use change is one of the main drivers of biodiversity loss worldwide, but its negative effects can vary depending on the spatial scale analyzed. Considering the continuous expansion of agricultural demand for land, ... -
Improved Stability of Human CGI-58 Induced by Phosphomimetic S237E Mutation
(American Chemical Society, 2022)"In lipolysis, the activating function of CGI-58 is regulated by its interaction with perilipin 1 (PLIN1) localized on the lipid droplet (LD), and its release is controlled by phosphorylation. Once lipolysis is stimulated ... -
