Disease Activity in Rheumatoid Arthritis Patients Stratified by Hemoglobin Levels: A Multi-center Study

Oman Medical Journal
Objectives: Hemoglobin (Hb) level and its relation to rheumatoid arthritis (RA) is multifactorial. The primary aim of this study was to examine the association between Hb levels and disease activity in patients with RA.

Magnetic mechanism for the biological functioning of hemoglobin [PDF]

arXiv, 2019
The role of magnetism in the biological functioning of hemoglobin has been debated since its discovery by Pauling and Coryell in 1936. The hemoglobin molecule contains four heme groups each having a porphyrin layer with a Fe ion at the center. Here, we present combined density-functional theory and quantum Monte Carlo calculations for an effective ...

EEG Spectral Exponents and Visual Chirp Responses Mirror Anti‐Seizure Medication Load in Refractory Focal Epilepsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Quantitative markers of cortical excitability may help identify responders to anti‐seizure medications (ASMs). We studied the relationship between ASM load and two electroencephalography (EEG) markers of cortical excitability in people with refractory epilepsy. Methods We included individuals with refractory focal epilepsy undergoing

Incidence of Side Effects Associated With Acetaminophen in People Aged 65 Years or More: A Prospective Cohort Study Using Data From the Clinical Practice Research Datalink

Arthritis Care &Research, EarlyView.
Objective The main objective of this study is to examine the safety of oral acetaminophen at its therapeutic dose in adults aged ≥65 years. Methods This population‐based cohort study used the Clinical Practice Research Datalink‐Gold data. Participants were aged ≥65 years registered with a UK general practice for at least 12 months between 1998 and 2018.

Red blood cells in cerebrospinal fluid as possible inhibitory factor for enterovirus RT-PCR

Arquivos de Neuro-Psiquiatria
The presence of hemoglobin in samples are considered an important inhibitory factor for polymerase chain reaction (PCR). The aim of this study was to examine the influence of red blood cells (RBC)s in cerebrospinal fluid (CSF) as an inhibitory factor to ...

Cation modulation of hemoglobin interaction with sodium n-dodecyl sulphate (SDS) iv: magnesium modulation at pH 7.20

AIMS Biophysics, 2016
We investigate the interaction of Mg2+ (0–2.30 mM) and sodium n-dodecyl sulfate (SDS) with hemoglobins (Hbs) A and S at pH 7.20. SDS was used to model both membranes (0.60 mM SDS) and proteases (5.0 mM SDS). Via UV-visible spectroscopy, second derivative

Is Hemoglobin Antigenic? [PDF]

Journal of Infectious Diseases, 1919
Thus in work reported by Leblanc,1 a precipitin for beef hemoglobin was obtained by immunizing a dog with a preparation obtained by saturating laked, washed, red cells with ammonium sulphate after removal of globulins and stromata. This preparation was by no means pure since no attempt was made to free the hemoglobin from possible contamination by ...

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Optical Marking of Alcohol Induced Hemoglobin Modification [PDF]

arXiv, 2007
It has been shown that conformational modifications of Hb induced by ethanol consumption can be visualized in optical spectra studying oxygenation kinetics of hemoglobin or mixing hemoglobin with Cibacron blue dye. Better dye affinity of blood proteins extracted from alcoholised rats with respect to those from non-alcoholised ones confirms that ethanol

Low proportions of glycosylated hemoglobin associated with hemoglobin S and hemoglobin C.

Clinical Chemistry, 1979
Abstract Using a cation-exchange chromatographic method, we found normal or subnormal values for glycosylated hemoglobin in a few diabetic patients with persistent hyperglycemia. Subsequent investigations revealed that these unexpected results had originated from black patients with diabetes.
