Nitrogen fixation in the western English Channel (NE Atlantic Ocean) [PDF]

open access: yes, 2009
In temperate Atlantic waters (18.8 to 20.1°C), biological nitrogen fixation has beendemonstrated by 2 independent measurements: 15N-N2 incorporation and nifH identification in theDNA and expressed messenger RNA (mRNA).

Metabolic Engineering Escherichia coli for the Production of Lycopene

open access: yesMolecules, 2020
Lycopene, a potent antioxidant, has been widely used in the fields of pharmaceuticals, nutraceuticals, and cosmetics. However, the production of lycopene extracted from natural sources is far from meeting the demand.

UK DRAFFT : a randomised controlled trial of percutaneous fixation with kirschner wires versus volar locking-plate fixation in the treatment of adult patients with a dorsally displaced fracture of the distal radius [PDF]

open access: yes, 2011
Background: Fractures of the distal radius are extremely common injuries in adults. However, the optimal management remains controversial. In general, fractures of the distal radius are treated non-operatively if the bone fragments can be held in ...

Retrospective review of patients with testicular torsion in a University Hospital in Bahrain

open access: yesUrology Annals, 2023
Introduction: Testicular torsion is a surgical emergency that, with delayed treatment, may be associated with loss of the testis. It commonly presents with sudden onset testicular pain, vague lower abdominal pain, nausea, and vomiting.

Fixation Probabilities and Fixation Times in a Subdivided Population [PDF]

open access: yesEvolution, 1981
The rate of genetic evolution depends in part on the probabilities of fixation and times to fixation of alleles of different types. Using a diffusion approximation to the Wright-Fisher model of selection and genetic drift in a single panmictic population, Kimura (1962) found a general formula for the probability of fixation at a diallelic locus with ...

Individual differences in infant fixation duration relate to attention and behavioral control in childhood [PDF]

open access: yes, 2014
Individual differences in fixation duration are considered a reliable measure of attentional control in adults. However, the degree to which individual differences in fixation duration in infancy (0–12 months) relate to temperament and behavior in ...
