purine/fever

Unlike Borrelia burgdorferi, the relapsing fever agent Borrelia hermsii and the related Borrelia miyamotoi had purA and purB genes of the purine salvage pathway. These were located among the rRNA genes. Phylogenetic analysis indicated that these genes had a different evolutionary history than those

Energy deprivation increases sensitivity to killing by hyperthermia. Hypoxic cells become dramatically sensitive to heat under glycolytic inhibition or glucose deprivation. To define the role of glucose metabolism in hypoxic cells in the presence or absence of elevated temperatures, cell culture

Extracellular purine nucleotide and nucleoside signalling molecules, such as ATP and adenosine, acting through specific receptors (P2 and P1, respectively) play significant roles in the mechanisms underlying the febrile response. A variety of P2 and P1 receptor subunits have been identified in the

Intensified adenosine triphosphate (ATP) degradation following therapeutic hyperthermia is often observed in solid tumors. As a result, accumulation of purine catabolites can be expected together with formation of protons at several stages during degradation to the final product, uric acid. Proton

We studied the sensitivity against heavy ion beam and hyperthermia on radioresistant procaryote, Deinococcus radiodurans, for the purpose of cancer therapy. First, we examined the decrease of the survival rate and molecular weight of DNA purified from this cell by acid heat treatment. These

A reconstituted transcription system composed of the Rift Valley fever phlebovirus (Bunyaviridae family) proteins L and N expressed via recombinant vaccinia viruses and an S-like model RNA containing the CAT gene in the antisense orientation, has been described previously by Lopez et al. (J. Virol.,

Neopterin is an intermediate purine metabolite which can be determined in serum and has been shown to be elevated in processes that stimulate cell mediated immunity. Neopterin serum levels have been measured in 37 patients diagnosed of boutonneuse mediterranean fever. Serum titers were higher during

The Crimean-Congo Hemorrhagic Fever (CCHF) is an infectious disease of high virulence and mortality caused by a negative sense RNA nairovirus. The genomic RNA of CCHFV is enwrapped by its nucleoprotein. Positively charged residues on CCHFV nucleoprotein provide multiple binding sites to facilitate

BACKGROUND The use of Escherichia coli purine nucleoside phosphorylase (PNP) to activate fludarabine has demonstrated safety and antitumor activity during preclinical analysis and has been approved for clinical investigation. METHODS A first-in-human phase I clinical trial (NCT 01310179; IND 14271)

In the previous reports regarding thermoregulation, the hypothalamus is thought to be the primary centre in the central nervous system for controlling the body temperature. However, to date, there has not been sufficient evidence to reveal its thermoregulatory mechanism. In the current study, we

Purine nucleoside phosphorylase deficiency is a rare autosomal recessive immunodeficiency disease. The characteristic features of the disease include severe T cell immune defects with recurrent infections, a failure to thrive, and progressive neurological findings. To date, 35 cases of purine

Genome sequencing projects on two relapsing fever spirochetes, Borrelia hermsii and Borrelia turicatae, revealed differences in genes involved in purine metabolism and salvage compared to those in the Lyme disease spirochete Borrelia burgdorferi. The relapsing fever spirochetes contained six open

Influenza virus infection (IVI) and dengue virus infection (DVI) are major public health threats. Between IVI and DVI, clinical symptoms can be overlapping yet infection-specific, but host metabolome changes are not well-described. Untargeted metabolomics and targeted oxylipinomic analyses were

Hyperthermia is under intensive investigation as a treatment for tumors both alone and in combination with other therapeutic agents. Hyperthermia has a profound effect on the function and structural integrity of tumor microvasculature; this has often been cited as a reason for its effectiveness in
