Does poly-β-hydroxybutyrate interfere with nitrogen fixation in bacteroids? [PDF]

open access: yes, 2001
While most rhizobia accumulate poly--hydroxybutyrate (PHB) during free-living reproductive growth, not all of them are able to store the polymer in symbiotic life. The role of PHB during nitrogen fixation in bacteroid state is still unclear.

The Fracture Ankle Implant Review (FAIR) study: a national multicentre retrospective review of practice in implant choice, fixation methods, and outcomes in fixation of the fibula in ankle fractures

open access: yesBone & Joint Open
Aims: In fixation of the fibula in ankle fractures, the AO Foundation advocates using a lag screw and one-third tubular neutralization plate for simple patterns. Where a lag screw cannot be placed, bridging fixation is required.

Symbiotic nitrogen fixation Chapter 10 [PDF]

open access: yes, 1965
Chapters 1 and 16 describe the origin of the nitrogen cycle, the distribution of nitrogen in the biosphere, and the processes, including fixation,that maintain equilibrium between molecular and combined nitrogen.

Salicylic and succinic acids as inducers of phytoimmunity in winter wheat for the management of powdery mildew (Blumeria graminis (DC) Speer f. sp. tritici)

open access: yesBMC Plant Biology
Background Growth regulators play an important role in activating the main signal transduction pathways in response to stress, and their activity is key in the general mechanism to understanding the formation of phytoimmunity under biotic stress.

Intraocular soluble intracellular adhesion molecule-1 correlates with subretinal fluid height of diabetic macular edema

open access: yesIndian Journal of Ophthalmology, 2014
Objective: To investigate the correlations between aqueous concentrations of vascular endothelial growth factor (VEGF), monocyte chemoattractant protein-1 (MCP-1), soluble intracellular adhesion molecule-1 (sICAM-1) and diabetic macular edema (DME ...

Genome Sequence of Klebsiella oxytoca M5al, a Promising Strain for Nitrogen Fixation and Chemical Production [PDF]

open access: yes
Klebsiella oxytoca is an important microorganism for nitrogen fixation and chemical production. Here, we report an annotated draft genome of K. oxytoca strain M5al that contains 5,256 protein-coding genes and 95 structural RNAs, which provides a genetic ...

Novel aspects of nitrogen-fixation [PDF]

open access: yes, 1977
Only a fraction of the total agricultural need for nitrogen comes from natural or synthetic fertilizers. The remainder is satisfied largely through the biological fixation of atmospheric nitrogen. Whilst this is most efficiently effected by the Rhizobium-

Aerobic nitrogen fixation in Azotobacter vinelandii [PDF]

open access: yes, 1977
I ELECTRON DONATION TO NITROGENASEPaper I shows that the hypothesis, that a high ratio of (NADH + NADPH) / (NAD + + NADP + ) is the source of reducing power for nitrogenase in intact A.vinelandii, is invalid.

Guiding binocular saccades during reading: a TMS study of the PPC

open access: yesFrontiers in Human Neuroscience, 2011
Reading is an activity based on complex sequences of binocular saccades and fixations. During saccades, the eyes do not move together perfectly: saccades could end with a misalignment, compromising fused vision. During fixations, small disconjugate drift
