Migraines Are Correlated with Higher Levels of Nitrate-, Nitrite-, and Nitric Oxide-Reducing Oral Microbes in the American Gut Project Cohort. [PDF]

open access: yes, 2016
Nitrates, such as cardiac therapeutics and food additives, are common headache triggers, with nitric oxide playing an important role. Facultative anaerobic bacteria in the oral cavity may contribute migraine-triggering levels of nitric oxide through the ...

Nitric oxide and glomerulonephritis [PDF]

open access: yesKidney International, 2002
The glomerulus is a unique vascular network with the potential to express several isoforms of nitric oxide synthase (NOS). Induction of inducible NOS (iNOS) occurs as part of a rapid initial response to immune injury in glomerulonephritis (GN). Studies on rodent models suggest that this is due to activation of transcription factors by reactive oxygen ...

Biotransformation of Nitric Oxide [PDF]

open access: yesEnvironmental Health Perspectives, 1987
Previous investigations into the health effects of nitrogen oxides (NOx) have mostly been conducted with special reference to nitrogen dioxide (NO2) and its direct effects on the respiratory system, while the study of nitric oxide (NO) has been disregarded.

In vitro and in vivo TNFa synthesis modulation by methylguanidine, an uremic catabolyte [PDF]

open access: yes, 1999
Original article can be found at: http://www.sciencedirect.com/science/journal/00243205 Copyright Elsevier Inc.We have investigated whether methylguanidine (MG), an uremic toxin, modulates the expression of the inducible nitric oxide synthase (iNOS) and ...

Endothelium-derived relaxing factor produced and released from artery and vein is nitric oxide.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1987
The objective of this study was to determine whether nitric oxide (NO) is responsible for the vascular smooth muscle relaxation elicited by endothelium-derived relaxing factor (EDRF).

Reduced pressure pain thresholds in response to exercise in chronic fatigue syndrome but not in chronic low back pain: an experimental study [PDF]

open access: yes, 2010
Objective The aims of this study were to examine (i) base line pressure pain thresholds in patients with chronic fatigue syndrome and those with chronic low back pain compared with healthy subjects, (ii) the change in mean pain threshold in response to ...

Evaluation of the Binding Affinity of Nitrosylcobalamin to Intrinsic Factor as a Predictive Model for Cobalamin Binding Protein Interactions: A Comparative Study with Hydroxocobalamin

open access: yesFrontiers in Bioscience-Elite
Background: Intrinsic factor (IF) is a glycoprotein crucial for cobalamin (vitamin B12) absorption in the human body. This study aimed to evaluate the binding affinity of nitrosylcobalamin (NO-Cbl), a cobalamin analog, to recombinant ...

Nitric oxide and reproduction [PDF]

open access: yesMolecular Human Reproduction, 1997
639 tion. Moreover, local synthesis of NO within the uterus may be important for regulating myometrial activity, i.e. spontaneous contraction and relaxation of the uterus. Buhimschi et al. (1996) demonstrated that the rat cervix expressed all three isoforms of NOS (iNOS, nNOS, eNOS), whereas the uterus expressed only iNOS and eNOS, but not nNOS ...

The L-arginine-nitric oxide pathway.

open access: yesNew England Journal of Medicine, 1993
The discovery that mammalian cells generate nitric oxide, a gas previously considered to be merely an atmospheric pollutant, is providing important information about many biologic processes. Nitric oxide is synthesized from the amino acid L-arginine by a
