The Department of Environmental Science, The University of Arizona (UA), Tucson, Arizona 85721, USA; School of Natural Resources and Environment, NWAFU-UA Microcampus, Yangling, Shaanxi 712100, China. Electronic address:

Biochar is an environmentally friendly adsorbent material with excellent adsorption performance due to its extensive pore structure, large specific surface area, and numerous surface functional groups. It is commonly used to treat inorganic and organic pollutants. In recent years, with increasing focus on controlling soil pollution caused by heavy metals such as cadmium (Cd) and lead (Pb), the potential application of biochar has attracted much attention.

Aged Microplastics and Antibiotic Resistance Genes: A Review of Aging Effects on Their Interactions.

Antibiotics (Basel)

October 2024

School of Natural Resources and Environment, UA Microcampus, Northwest A&F University (NWAFU), Yangling 712100, China.

Microplastic aging affects the dynamics of antibiotic resistance genes (ARGs) on microplastics, yet no review presents the effects of microplastic aging on the associated ARGs. This review, therefore, aims to discuss the effects of different types of microplastic aging, as well as the other pollutants on or around microplastics and the chemicals leached from microplastics, on the associated ARGs. It highlights that microplastic photoaging generally results in higher sorption of antibiotics and ARGs due to increased microplastic surface area and functional group changes.

Mercury (Hg) and lead (Pb) pose significant risks to human health due to their high toxicity and bioaccumulative properties. This study aimed to develop a novel biochar composite (HMB-S), polyfunctionalized with manganese dioxide (α-MnO) and sulfur functional groups, for the effective immobilization of Hg(II) and Pb(II) from contaminated environments. HMB-S demonstrated superior adsorption capacities of 190.

Article Synopsis
  • Composting is driven by microorganisms and can be boosted by adding biochar or specific microorganisms, as explored in a study comparing four different treatment methods for composting dewatered sludge waste and wheat straw.
  • The study found that adding the newly isolated strain Xenophilus azovorans (XPA) or biochar-immobilized XPA (BCI-XPA) extended the thermophilic phase and improved seed germination, with BCI-XPA showing the highest effectiveness in enhancing microbial activity and diversity.
  • Carbon emissions increased with treatments involving XPA and BCI-XPA, which also promoted the formation of humic acids and altered pathways for organic material degradation, indicating their potential to enhance composting efficiency.

The impact of biogas residual biochar (BRB) on the humification and carbon balance process of co-composting of hog slurry (HGS) and wheat straw (WTS) was examined. The 50-day humification process was significantly enhanced by the addition of BRB, particular of 5% BRB, as indicated by the relatively higher humic acid content (67.28 g/kg) and humification ratio (2.

Feature at a Glance: Nonadherence to hypertension medications is associated with negative health outcomes, which is of particular importance for older adults because of the high prevalence of hypertension in this population. To promote medication adherence among this group, we translated a behavioral intervention that improved adherence by 36% into a digital therapeutic self-management system. Design strategies included interviewing older adults, conducting usability evaluations after each iteration, and engaging a team of experts from nursing, cognitive psychology, pharmacy, human factors in aging, and software development.

Patients with diabetes with coronary microvascular disease (CMD) exhibit higher cardiac mortality than patients without CMD. However, the molecular mechanism by which diabetes promotes CMD is poorly understood. RNA-binding protein human antigen R (HuR) is a key regulator of mRNA stability and translation; therefore, we investigated the role of HuR in the development of CMD in mice with type 2 diabetes.
