Infectious Disease Division, Moffitt Cancer Center, 12902 USF Magnolia Drive, Tampa, FL 33612, USA.

() is a known cause of a food poisoning in the general population. However, it can cause life-threatening sepsis and shock in severely immunocompromised patients with hematologic malignancies, which frequently lead to central nervous system (CNS) infections associated with high mortality and morbidity. In this case report, we describe a patient with a newly diagnosed acute myeloid leukemia that underwent induction chemotherapy and developed infection that was associated with septic shock and brain abscesses.

Reversal of genetic brain iron accumulation by N,N'-bis(2-mercaptoethyl)isophthalamide, a lipophilic metal chelator, in mice.

Arch Toxicol 2022 Jul 21;96(7):1951-1962. Epub 2022 Apr 21.

Department of Biomedical and Nutritional Sciences, University of Massachusetts Lowell, Lowell, MA, USA.

N,N'-bis(2-mercaptoethyl)isophthalamide (NBMI) is a novel lipophilic metal chelator and antioxidant used in mercury poisoning. Recent studies have suggested that NBMI may also bind to other metals such as lead and iron. Since NBMI can enter the brain, we evaluated if NBMI removes excess iron from the iron-loaded brain and ameliorates iron-induced oxidative stress. Read More

Specific recognition, intracellular assay and detoxification of fluorescent curcumin derivative for copper ions.

J Hazard Mater 2021 10 25;420:126490. Epub 2021 Jun 25.

State Key Laboratory of Southwestern Chinese Medicine Resources, School of Pharmacy, Chengdu University of Traditional Chinese Medicine, Chengdu 611137, China. Electronic address:

Recognition and excretion of metal ions play an important role in the diagnosis and treatment of various diseases and poisoning. Although copper (Cu) is a cofactor of many key enzymes in the human body, its accumulation caused by genetic ATP7B mutation or environmental pollution can lead to hepatotoxicity, renal failure, Wilson's disease, inflammation, and even Parkinson's disease (PD) and Alzheimer's disease (AD). Therefore, in this work, a difluoroboron curcumin derivative (DF-Cur) was used for the specific recognition of copper ions (Cu). Read More

Near-infrared light excited UCNP-DNAzyme nanosensor for selective detection of Pb and in vivo imaging.

Talanta 2021 May 29;227:122156. Epub 2021 Jan 29.

Key Laboratory of Chemical Biology and Traditional Chinese Medicine Research, College of Chemistry and Chemical Engineering, Hunan Normal University, Changsha, 410081, PR China. Electronic address:

Due to similar charges, atomic radii, and chemical properties of most metal ions, the selective sensing of these metal ions and imaging in vivo is still a challenge. A DNAzyme assemblied and near-infrared (NIR) light excited nanosensor was developed to detect and image Pb. In this nanosensor, NaYF:Yb, Er upconversion nanoparticles (UCNPs) introduced as NIR-to-Vis transducer were the donor of luminescence resonance energy transfer (LRET), and DNAzyme-functionalized black hole quencher 1 (BHQ1) acted as energy transfer acceptor.

Whole-brain R1 predicts manganese exposure and biological effects in welders.

Arch Toxicol 2020 10 1;94(10):3409-3420. Epub 2020 Sep 1.

School of Health Sciences, Purdue University, 550 Stadium Dr., Hampton Hall of Civil Engineering, West Lafayette, IN, 47907, USA.

Manganese (Mn) is a neurotoxicant that, due to its paramagnetic property, also functions as a magnetic resonance imaging (MRI) T1 contrast agent. Previous studies in Mn toxicity have shown that Mn accumulates in the brain, which may lead to parkinsonian symptoms. In this article, we trained support vector machines (SVM) using whole-brain R1 (R1 = 1/T1) maps from 57 welders and 32 controls to classify subjects based on their air Mn concentration ([Mn]), Mn brain accumulation (ExMn), gross motor dysfunction (UPDRS), thalamic GABA concentration (GABA), and total years welding.

Diagnostic utility of arterial spin labeling in identifying changes in brain perfusion in patients with carbon monoxide poisoning.

Clin Imaging 2020 Aug 11;64:92-96. Epub 2020 Apr 11.

Department of Emergency Medicine, University of Health Sciences, Konya Training and Research Hospital, Konya, Turkey.

Objective: Carbon monoxide (CO) poisoning is one of the most common poisonings worldwide. The affinity of hemoglobin for CO is significantly higher than that for oxygen, and the formation of carboxy-hemoglobin leads to a decrease in the capacity of blood to transport oxygen to tissues, tissue hypoxia, and early perfusion changes in the affected tissue. This study aimed to investigate the utility of arterial spin labeling perfusion imaging (ASL-PI) in revealing cerebral vascular hemodynamic changes in patients presenting to the emergency room with CO poisoning and to compare findings with those from diffusion-weighted imaging (DWI).
