Genomic changes in the biological control agent associated with introduction.

Biological control is the main purpose of intentionally introducing non-native invertebrate species. The evolutionary changes that occur in the populations of the introduced biological control agents may determine the agent's efficiency and the environmental safety. Here, to explore the pattern and extent of potential genomic changes in the worldwide introduced predatory ladybird beetle , we used a reduced-representation sequencing method to analyze the genome-wide differentiation of the samples from two native and five introduced locations.

Patients with supratentorial aneurysmal subarachnoid hemorrhage during the intermediate period: waiting or actively treating.

Perhaps the most difficult practical decision for neurosurgeons these days is whether to secure aneurysms during the intermediate period (4-10 days) after aneurysmal subarachnoid hemorrhage (SAH). We retrospectively reviewed a series of 115 patients with a Hunt-Hess grade I-III upon admission who were admitted 4-10 days after initial supratentorial aneurysmal SAH. Patients who underwent active treatment in the intermediate period were assigned to the intermediate group (n = 49) while those who accepted delayed obliteration of a ruptured aneurysm (11-30 days) were assigned to the late group (n = 66).
