Potassium hydroxide activation of microalgal biochar for improved adsorption efficiency

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Activated carbon was prepared from Chlorella by carbonization and potassium hydroxide activation, and its structural properties and methylene blue (MB) adsorption performance were evaluated. Raw Chlorella exhibited an adsorption capacity of 287.2 mg g−1, which decreased to 214.8 mg g−1 after carbonization.

Drug induced methemoglobinemia: a case report

, 2022
Methemoglobinemia (MetHb) is an uncommon cause of central cyanosis and hence, not frequently considered in the differential diagnosis. Methemoglobin is an abnormal form of hemoglobin which is produced physiologically due to autooxidation. If this process

Methemoglobinemia Caused by an Inert Ingredient after Intentional Ingestion of Pesticide [PDF]

Korean Journal of Critical Care Medicine, 2014
We report two cases of toxic methemoglobinemia caused by an inert ingredient in pesticide product after intentional ingestion of pesticide. First, 51-year-old male visited to the emergency department (ED) after the ingestion of pesticide in a suicide ...

Organic Nitrate-Induced Methemoglobinemia

, 1989
Metabolism of organic nitrates results in the formation of inorganic nitrites that can oxidize hemoglobin to methemoglobin. Clinical trials have investigated the risk of developing methemoglobinemia during the therapeutic use of organic nitrates.

Prenatal Exome Sequencing Identifies Dual Maternal‐Fetal Diagnosis of HbF Mission Bay, a Novel HBG2 Variant Associated With Methemoglobinemia, Hypoxia and Hemolytic Anemia

Prenatal Diagnosis, EarlyView.
ABSTRACT Prenatal exome sequencing (ES) can establish rare genetic diagnoses in a fetus but may also lead to occult genetic diagnosis in a biological parent. We present a case of dual fetal and maternal diagnosis by prenatal ES, in a fetus with unexplained anemia and in a pregnant patient with sickle cell disease (SCD) and recurrent unexplained hypoxia.

Nitrogen Policy for Sustainable Agriculture in the US: Estimating Socially Optimal Application Rates and Economic Impacts

Sustainable Development, EarlyView.
ABSTRACT Nitrogen (N) application creates negative externalities via nitrate (NO3−) leaching that threatens human health and the emission of nitrous oxide (N2O), a potent greenhouse gas. This study determines socially optimal nitrogen application rates (SONR) for corn and wheat by considering the social costs of both pollutants. The assessment includes
