Processed Dietary Fiber Partially Hydrolyzed Guar Gum Increases Susceptibility to Colitis and Colon Tumorigenesis in Mice.

The vital role of naturally occurring dietary fibers (DFs) in maintaining intestinal health has fueled the incorporation of isolated DFs into processed foods. A select group of soluble DFs, such as partially hydrolyzed guar gum (Phgg), are being promoted as dietary supplements to meet recommended DF intake. However, the potential effects of regular consumption of these processed DFs on gastrointestinal health remain largely unknown.

Selenoproteome depletion enhances oxidative stress and alters neutrophil functions in Citrobacter rodentium infection leading to gastrointestinal inflammation.

Reactive oxygen species (ROS) play a critical role in modulating a range of proinflammatory functions in neutrophils, as well as regulating neutrophil apoptosis and facilitating the resolution of an inflammatory response. Selenoproteins with the 21st amino acid, selenocysteine (Sec), regulate immune mechanisms through the modulation of redox homeostasis aiding in the efficient resolution of inflammation, while their role in neutrophil functions during diseases remains unclear. To study the role of selenoproteins in neutrophils during infection, we challenged the granulocyte-specific tRNA (Trsp) knockout mice (Trsp) with Citrobacter rodentium (C.

Spinal metastases in primary thyroid malignancies: Single center experience of 44 cases.

Background: Patients with differentiated thyroid carcinoma have a 10 year survival rate of more than 95%. However, the existence of spinal metastases significantly reduces overall survival. In this study, we review the epidemiology and outcomes of patients with thyroid malignancies with spinal metastases.

The Impact of Sodium Selenite and Seleno-L-Methionine on Stress Erythropoiesis in a Murine Model of Hemolytic Anemia.

Background: Selenium (Se) is an essential trace element that exerts most biological activities through selenoproteins. Dietary selenium is a key regulator of red cell homeostasis and stress erythropoiesis. However, it is unknown whether the form and increasing doses of Se supplementation in the diet impact stress erythropoiesis under anemic conditions.

LC-MS-Based Simultaneous Determination of Biomarkers in Dried Urine Spots for the Detection of Cofactor-Dependent Metabolic Disorders in Neonates.

Deficiency of cofactors for various enzymes can lead to inborn errors of metabolism. These conditions frequently occur as seizures, which lead to permanent brain damage. Newborn screening for biomarkers associated with these disorders can help in early detection and treatment.
