No wonder, it is a hybrid. Natural hybridization between and revealed by molecular marker systems and its potential ecological impact.

Progressive changes in the environment are related to modifications of the habitat. Introducing exotic species, and interbreeding between species can lead to processes that in the case of rare species or small populations threatens their integrity. Given the declining trends of many populations due to increased hybridization, early recognition of hybrids becomes important in conservation management.

What nature separated, and human joined together: About a spontaneous hybridization between two allopatric dogwood species (Cornus controversa and C. alternifolia).

In this study, possible hybridization between two allopatric species, Cornus controversa and Cornus alternifolia, was explored using molecular and morphological approaches. Scanning electron microscope analyses of the adaxial and the abaxial leaf surfaces yielded a few new not yet described characters typical for the particular species and intermediate for hybrids. With the use of 14 Random Amplified Polymorphic DNA and 5 Amplified Fragment Length Polymorphism primer combinations, 44 fragments species specific to C.

The role and diagnostic potential of gastrokine 1 in gastric cancer.

Introduction: Gene for () was identified as one of the most significant in gastric cancer and indicated as a potential therapeutic target.

Aim: The aim was a review of literature reports concerning the role and diagnostic potential of GKN1 in gastric cancer.

Materials And Methods: PubMED database was searched for sources using the following keywords: gastrokine 1/GKN1/AMP-18 and gastric cancer, , aspirin, nonsteroidal anti-inflammatory drugs.

Markers of inflammation and influence of nitric oxide on platelet activation in the course of .

Ulcerative colitis is a non-specific inflammatory bowel disease of unknown etiology. We investigated whether severe form of ulcerative colitis may lead to increased number of platelets, changes in platelet parameters and their activation. To address our objectives, we measured concentrations of nitric oxide and markers of inflammation.
