Background: The production of recombinant proteins for therapeutic use represents a great impact on the biotechnology industry. In this context, established mammalian cell lines, especially CHO cells, have become a standard ...

Azotobacter vinelandii is a bacterium obligate aerobe able to fix nitrogen and grow under microaerophilic conditions. This microorganism has remarkable cellular machinery with the ability to biosynthesize three molecules ...

This paper reviews the recently enacted Chilean National Aquaculture Policy (NAP). It goes through its central objective, summarises its main components and points out the main actions already underway by the government ...

Precursor cells of skeletal muscles express connexins 39, 43 and 45 and pannexin1. In these cells, most connexins form two types of membrane channels, gap junction channels and hemichannels, whereas pannexin1 forms only ...

Mammals express ∼20 different connexins, the main gap junction forming proteins in mammals, and 3 pannexins, homologs of innexins, the main gap junction forming proteins in invertebrates. In both classes of gap junction, ...

Context. We have obtained deep infrared images and k-band spectra of the Galactic globular cluster 2 MASS GC 02. A variable star search has also been carried out. Aims. Some basic physical properties of the cluster, such ...

In Quesiti et Inventlone diverse (1546), Niccolfc Tartaglia presented a theory of projectile motion centred on the resistance opposed by air and its subsequent division. I propose that this explanation is based on three ...

To develop ways to catch fewer undersized specimens of Jasus frontalis in the traps of the rock lobster fishery off the Juan Fernández Archipelago (Chile), we studied the use of lobster traps with different-sized escape ...

Sustained stimulation of the intrarenal/intratubular renin-angiotensin system in a setting of elevated arterial pressure elicits renal vasoconstriction, increased sodium reabsorption, proliferation, fibrosis, and eventual ...
