Increased CD39 nucleotidase activity on microparticles from patients with idiopathic pulmonary arterial hypertension. [PDF]
BACKGROUND:Idiopathic pulmonary arterial hypertension (IPAH) is a devastating disease characterized by increased pulmonary vascular resistance, smooth muscle and endothelial cell proliferation, perivascular inflammatory infiltrates, and in situ ...

A neutrophil-dependent pathway for the generation of a neutral peptide mediator: partial characterization of components and control by alpha-1-antitrypsin. [PDF]
A biologically active neutral peptide mediator is cleaved from a plasma protein substrate by an alpha-1-antitrypsin-inhibitable serine protease apparently residing on the membrane of the human neutrophil. The peptide mediator has an approximate mol wt of

Snake Venomics and Antivenomics of Bothrops diporus, a Medically Important Pitviper in Northeastern Argentina [PDF]
Snake species within genus Bothrops are responsible for more than 80% of the snakebites occurring in South America. The species that cause most envenomings in Argentina, B.

The Characterization of Escherichia coli CpdB as a Recombinant Protein Reveals that, besides Having the Expected 3´-Nucleotidase and 2´,3´-Cyclic Mononucleotide Phosphodiesterase Activities, It Is Also Active as Cyclic Dinucleotide Phosphodiesterase. [PDF]
Endogenous cyclic diadenylate phosphodiesterase activity was accidentally detected in lysates of Escherichia coli BL21. Since this kind of activity is uncommon in Gram-negative bacteria, its identification was undertaken.

Activity-dependent release of Adenosine: a critical re-evaluation of mechanism [PDF]
Adenosine is perhaps the most important and universal modulator in the brain. The current consensus is that it is primarily produced in the extracellular space from the breakdown of previously released ATP.

Objective Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro. Methods ITPA enzymatic activity

A nucleotide metabolite controls stress-responsive gene expression and plant development.
Abiotic stress, such as drought and high salinity, activates a network of signaling cascades that lead to the expression of many stress-responsive genes in plants. The Arabidopsis FIERY1 (FRY1) protein is a negative regulator of stress and abscisic acid (

Diabetic encephalopathy (DME) impairs neurobehavior, neurochemicals, oxidative stress, and inflammation. This study evaluated the effects of hesperidin (HSP), exercise (EX), and acarbose (ACA) alone or combined on diabetic rats. Treatments reduced AChE, BChE, ACE, arginase, ATPDase, 5′‐nucleotidase, ADA, LDH, TBARS, and ROS, while increasing IL‐10, SOD,

Background There is evidence that impaired metabolism play an important role in the etiology of many neuropsychiatric disorders. Although this has not been investigated to date, several recent studies proposed that nitrogen metabolism-related parameters ...
