Computational genomic analysis of hemorrhagic fever viruses. Viral selenoproteins as a potential factor in pathogenesis.

Numai utilizatorii înregistrați pot traduce articole

A number of distinct viruses are known as hemorrhagic fever viruses based on a shared ability to induce hemorrhage by poorly understood mechanisms, typically involving the formation of blood clots ("disseminated intravascular coagulation"). It is well documented that selenium plays a significant

Genomic structures of viral agents in relation to the biosynthesis of selenoproteins.

Numai utilizatorii înregistrați pot traduce articole

The genomes of both bacteria and eukaryotic organisms are known to encode selenoproteins, using the UGA codon for seleno-cysteine (SeC), and a complex cotranslational mechanism for SeC incorporation into polypeptide chains, involving RNA stem-loop structures. These common features and similar codon

Selenoprotein expression is essential in endothelial cell development and cardiac muscle function.

Numai utilizatorii înregistrați pot traduce articole

LoxP-Cre technology was used to remove the selenocysteine tRNA gene, trsp, in either endothelial cells or myocytes of skeletal and heart muscle to elucidate the role of selenoproteins in cardiovascular disease. Loss of selenoprotein expression in endothelial cells was embryonic lethal. A

Effect of Se on selenoprotein activity and thyroid hormone metabolism in beef and dairy cows and calves.

Numai utilizatorii înregistrați pot traduce articole

Although Se is essential for antioxidant and thyroid hormone function, factors influencing its requirement are not well understood. A survey and two experiments were conducted to determine the influence of cattle breed and age on selenoprotein activity and the effect of maternal Se supplementation

Selenium Deficiency-Induced Apoptosis of Chick Embryonic Vascular Smooth Muscle Cells and Correlations with 25 Selenoproteins.

Numai utilizatorii înregistrați pot traduce articole

Selenium deficiency is the major cause of exudative diathesis in chicks. Subcutaneous hemorrhage is one of the typical symptoms of the disease. However, the reason for the occurrence of blood exudation remains unknown. In the present study, the vascular smooth muscle cells (VSMCs) were isolated from

[Selenium and thyroidal function; the role of immunoassays].

Numai utilizatorii înregistrați pot traduce articole

It is well known that selenium plays a fundamental role in regulating thyroid and other functions of the human body like reproduction, autoimmunity, glucose metabolism or bone metabolism. While for thyroid function investigation, radioimmunoassays and radioimmunometric assays both key techniques of

Protective effect of seleno-L-methionine on cyclophosphamide-induced urinary bladder toxicity in rats.

Numai utilizatorii înregistrați pot traduce articole

Cyclophosphamide (CP) is a widely used antineoplastic drug, which could cause toxicity of the normal cells due to its toxic metabolites. Its urotoxicity may cause dose-limiting side effects like hemorrhagic cystitis. Overproduction of reactive oxygen species (ROS) during inflammation is one of the

Selenium deficiency associated porcine and human cardiomyopathies.

Numai utilizatorii înregistrați pot traduce articole

Selenium (Se) is a trace element playing an important role in animal and human physiological homeostasis. It is a key component in selenoproteins (SeP) exerting multiple actions on endocrine, immune, inflammatory and reproductive processes. The SeP family of glutathione peroxidases (GSH-Px)

Spontaneous premature birth as a target of genomic research.

Numai utilizatorii înregistrați pot traduce articole

Spontaneous preterm birth is a serious and common pregnancy complication associated with hormonal dysregulation, infection, inflammation, immunity, rupture of fetal membranes, stress, bleeding, and uterine distention. Heredity is 25-40% and mostly involves the maternal genome, with contribution of

The metal and metalloprotein profile of human plasma as biomarkers for stroke diagnosis.

Numai utilizatorii înregistrați pot traduce articole

Stroke, a major cause of disability and mortality, affects someone in the United States every 40s. Stroke biomarkers, including those that could be used as a blood test for diagnosis of stroke, have been particularly elusive. We performed a double blind study to identify human plasma biomarkers for

Selenium: implications for outcomes in extremely preterm infants.

Numai utilizatorii înregistrați pot traduce articole

Extremely preterm infants are at high risk for morbidities including bronchopulmonary dysplasia, intraventricular hemorrhage, and retinopathy of prematurity likely related to their exposure to reactive oxygen and nitrogen species early in life. Selenium is a trace mineral contributes to the proper

Selenium deficiency impaired immune function of the immune organs in young grass carp (Ctenopharyngodon idella).

Numai utilizatorii înregistrați pot traduce articole

This study aimed to investigate the effects of dietary selenium on resistance to skin haemorrhages and lesions and on immune function as well as the underlying mechanisms of those effects in the head kidney, spleen and skin of young grass carp (Ctenopharyngodon idella). A total of 540 healthy grass

Selenium Drives a Transcriptional Adaptive Program to Block Ferroptosis and Treat Stroke.

Numai utilizatorii înregistrați pot traduce articole

Ferroptosis, a non-apoptotic form of programmed cell death, is triggered by oxidative stress in cancer, heat stress in plants, and hemorrhagic stroke. A homeostatic transcriptional response to ferroptotic stimuli is unknown. We show that neurons respond to ferroptotic stimuli by induction of
