Whitehouse (1950): 1. Sudden rise of angiosperms during the Cretaceous period (144-65 million years ago) was due to the development of barriers for self-pollination forcing the flowering plants to out breed and resulted genetic variations and rapid expansion of the angiosperms. 2. 70% of the angiosperms are hermophrodite species, while no more than 5% dioecious. Such a high proportion of hermop...

Self-fertilization, which results in reduced fitness of offspring, is a common problem in hermaphrodite angiosperms. To prevent this, many plants utilize self-incompatibility (SI), which is determined by the multi-allelic S locus, that allows discrimination between self (incompatible) and non-self (compatible) pollen by the pistil. In poppy (Papaver rhoeas), the pistil S-determinant (PrsS) is a...

Rh incompatibility [4] occurs when a pregnant woman whose blood type is Rh-negative is exposed to Rh-positive blood from her fetus [5], leading to the mother?s development of Rh antibodies. These antibodies have the potential to cross the placenta [6] and attach to fetal red blood cells, resulting in hemolysis, or destruction of the fetus?s red blood cells. This causes the fetus [5] to become a...

In this paper, I discuss the analysis of logic in the pragmatic approach recently proposed by Brandom. I consider different consequence relations, formalized by classical, intuitionistic and linear logic, and I will argue that the formal theory developed by Brandom, even if provides powerful foundational insights on the relationship between logic and discursive practices, cannot account for imp...

In recent years, the microbiome has been recognized as a key regulator of immune responses. Evidence suggests that changes in the microbiome can lead to chronic disease and even exacerbation of the disease. Impairment of innate immunity resulting from microbial incompatibility may worsen host susceptibility to infection and exacerbate chronic lung diseases. Specific microbes play a key role in ...

This excellent pamphlet is published by Dr. Thos. Stephenson, the Editor of the well known and useful periodical, The Prescriber. Incompatibility, in the medical sense, has been defined by Dr. Walter Smith of Dublin a? "any unintentional change, which notably interferes with the elegance, usefulness, or safety of a prescription," and such changes may be chemical, physical (or pharmaceutical), o...

Iso-leukoagglutinins are known to develop primarily in multitransfused patients (1-6). A possibly different kind of agglutinin for white cells, such as that related to aminopyrine leukopenia, has also been described (7). The therapeutic administration of blood and of aminopyrine may not be the only stimuli for leukoagglutinin production. Two groups of investigators, Dausset, Nenna and Brecy (8)...
