Chromatin Structure in the Cellular Slime Mold Dictyostelium discoideum [PDF]

open access: yes, 1978
The structure of Dictyostelium discoideum chromatin has been studied by the following techniques: electron microscopy, staphylococcal nuclease digestion, acrylamide gel electrophoresis, sucrose gradient centrifugation, and melting.

Multilocus sequence types of invasive Corynebacterium diphtheriae isolated in the Rio de Janeiro urban area, Brazil [PDF]

open access: yes, 2012
Invasive infections caused by Corynebacterium diphtheriae in vaccinated and non-vaccinated individuals have been reported increasingly. In this study we used multilocus sequence typing (MLST) to study genetic relationships between six invasive strains of

A GABAergic projection from the centromedial nuclei of the amygdala to ventromedial prefrontal cortex modulates reward behavior [PDF]

open access: yes, 2016
The neural circuitry underlying mammalian reward behaviors involves several distinct nuclei throughout the brain. It is widely accepted that the midbrain dopamine (DA) neurons are critical for the reward-related behaviors.

Determination of individual sugars and organic acids of New Zealand varietal apple juice and their use in evaluating authenticity : a thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy in Food Technology at Massey University [PDF]

open access: yes, 1997
High pressure liquid chromatography techniques were used to determine sugars and acids in the juice of apples grown in New Zealand. A total of 189 samples were analysed and the results were used to assist with the determination of the authenticity of New

mGluR5 antagonism inhibits cocaine reinforcement and relapse by elevation of extracellular glutamate in the nucleus accumbens via a CB1 receptor mechanism. [PDF]

open access: yes, 2018
Metabotropic glutamate receptor 5 (mGluR5) antagonism inhibits cocaine self-administration and reinstatement of drug-seeking behavior. However, the cellular and molecular mechanisms underlying this action are poorly understood.

Sucrose versus maltose effect on metabolic pathways in somatic embryogenesis of Hevea brasiliensis [PDF]

open access: yes, 2004
Somatic embryogenesis in Hevea is stimulated when the embryogenesis induction medium contains maltose, rather than glucose, fructose, or sucrose, in equimolarity (Blanc et al., 1999).

Lyophilisation of influenza, rabies and Marburg lentiviral pseudotype viruses for the development and distribution of a neutralisation-assay based diagnostic kit [PDF]

open access: yes, 2014
Pseudotype viruses (PVs) are chimeric, replication-deficient virions that mimic wild-type virus entry mechanisms and can be safely employed in neutralisation assays, bypassing the need for high biosafety requirements and performing comparably to ...

THE BIOSYNTHESIS OF SUCROSE

open access: yesJournal of Biological Chemistry, 1955
The enzyme, which was named sucrose phosphorylase, has not been found in plant tissues (4), and thus the mechanism of sucrose synthesis remains obscure. Evidence obtained from tracer experiments led Buchanan et al. (5, 6) to assume that in plants sucrose phosphate is formed from UDPG’ and fructose-l-phosphate.

Manipulating the ensilage of wilted, unchopped grass through the use of additive treatments [PDF]

open access: yes, 2007
peer-reviewedBaled silage composition frequently differs from that of comparable conventional precision-chop silage. The lower final concentration of fermentation products in baled silage makes it more conducive to the activities of undesirable ...

Tumor Growth Increases Neuroinflammation, Fatigue and Depressive-like Behavior Prior to Alterations in Muscle Function [PDF]

open access: yes, 2015
Cancer patients frequently suffer from fatigue, a complex syndrome associated with loss of muscle mass, weakness, and depressed mood. Cancer-related fatigue (CRF) can be present at the time of diagnosis, during treatment, and persists for years after ...
