Does microbial biomass affect pelagic ecosystem efficiency? An experimental study

Bacteria and other microorganisms in the pelagic zone participate in the recycling of organic matter and nutrients within the water column. The microbial loop is thought to enhance ecosystem efficiency through...

Morphological alteration of fibroblasts mechanically stressed in a collagen lattice

The behavior of fibroblast-populated collagen lattices under mechanical stress was studied. Lattice retraction was blocked to allow the application of mechanical stress by contraction of the fibr...

A comparison of¹⁵N proline and¹³C leucine for monitoring protein biosynthesis in the skin

The tracers L¹⁵N-proline and L(1-¹³C)-leucine were used to explore the synthesis of skin proteins in vivo in rabbits. They orally received a single dose containing an equimolecular mixture of L(1-¹³C)-leucine and...

Urine glycyl-L-proline increase and skin trophicity

Glycyl-L-proline (gly-pro) is an end product of collagen metabolism that is further cleaved by prolidase (EC 3.4.13.9); the resulting proline molecules are recycled into collagen or other proteins. We postulat...

Mineralization and Alkaline Phosphatase Activity in Collagen Lattices Populated by Human Osteoblasts

Adult human osteoblastic cells were grown in a native type I collagen gel. Proliferation and viability analyses showed that cells rapidly stopped dividing and became blocked in the G0G1 phase (91% on day 13)....

Production of matrix metalloproteinase 2 in fibroblast reaction to mechanical stress in a collagen gel

The reaction of fibroblasts to mechanical forces generated by fibroblasts themselves in anchored collagen lattices was studied. Fibroblasts were cast in collagen gels. Free retracted gels (RG) were compared w...

Effects of vancomycin versus nafcillin in enhancing killing of methicillin-susceptible Staphylococcus aureus causing bacteremia by human cathelicidin LL-37

Recent studies have demonstrated that anti-staphylococcal beta-lactam antibiotics, like nafcillin, render methicillin-resistant Staphylococcus aureus (MRSA) more susceptible to killing by innate host defense pept...

The effect of the throat width of plug nozzles on the combustion mode in rotating detonation engines

Rotating detonation engines have been studied due to their better theoretical propulsion performance than that of deflagration-based engines. In this experimental study, the Laval nozzle throat width was varie...
