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

open access: yesPrenatal 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.

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

open access: yesFEBS Letters, Volume 600, Issue 2, Page 251-266, January 2026.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

A Novel Alpha1‐Variant (HBA1:c.‐35T>C) Complexed With the First Reported Hb M‐Saskatoon in the Chinese Population

open access: yesMolecular Genetics &Genomic Medicine, Volume 14, Issue 1, January 2026.
The research subjects were diagnosed with two distinct types of abnormal hemoglobin. Our study reports the first case of a complex hemoglobinopathy in China, characterized by the presence of the globally first‐reported alpha1 variant (HBA1:c.‐35T>C) and the initial identification of Hb M‐Saskatoon (HBB:c.190C>T) in China.

Dual versus single inhibitors: Which strategy best mitigates nitrogen losses in coarse‐textured soils? A laboratory evaluation

open access: yesSoil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Enhanced efficiency fertilizers, including urease inhibitors (UIs), nitrification inhibitors (NIs), and dual inhibitors (DIs [UI + NI]), are widely used to reduce nitrogen (N) losses and improve crop nitrogen use efficiency (NUE). However, their relative effectiveness across multiple nitrogen loss pathways remains unclear.

Clinical, metabolic, and molecular genetic characterization of hereditary methemoglobinemia caused by cytochrome b5 reductase deficiency in 30 dogs

open access: yesScientific Reports, 2020
Genotype–phenotype correlations of humans and dogs with hereditary methemoglobinemia are not yet well characterized. We determined total hemoglobin and methemoglobin (MetHb) concentrations, cytochrome b5 reductase (CYB5R) enzyme activities, genotypes ...
