Symbiosis and asymbiosis relative to Orchids

, : Symbiosis and asymbiosis relative to Orchids. New Phyldogist. 26: 5, 328-336

The writer's investigations on the germination of orchid seed have led to conclusions totally different from those reached by Costantin with regard to obligate symbiosis. Summing up his views, the author states that the changes induced by the fungus Rhisoctonia in the culture medium are of primary importance in the germination of the seed and early growth of the seedling.

Activation of the Bruton tyrosine kinase (BTK) pathway plays an important role in the pathophysiology of a number of B-cell lymphoproliferative disorders (LPDs). A number of preclinical studies support inhibiting BTK as a mechanism to treat LPDs....

In three foxhounds, diffusing capacity for carbon monoxide (DLCO) was reduced by 25-30% after left pneumonectomy. Based on previous morphometric data in animals and physiologic data in humans, this reduction should not result in any impairment in...
