Characteristics of submerged and partially submerged caves (habitat type 8330) in Romania.

Underwater sea caves form a relatively under-examined habitat type within the marine regions of Europe, although they provide unique physical conditions such as reduced light and wave energy, in addition to reduced temperature amplitude. This study aimed at revealing the characteristics of submerged cavities on the southern Romanian continental shelf where six protected areas exist. We used high-resolution bathymetry data and side-scan sonar imaging to identify limestone outcrops where cavities would be most probable to form and then performed visual observation during SCUBA diving activities.

Heavy reliance on plants for Romanian cave bears evidenced by amino acid nitrogen isotope analysis.

Heavy reliance on plants is rare in Carnivora and mostly limited to relatively small species in subtropical settings. The feeding behaviors of extinct cave bears living during Pleistocene cold periods at middle latitudes have been intensely studied using various approaches including isotopic analyses of fossil collagen. In contrast to cave bears from all other regions in Europe, some individuals from Romania show exceptionally high δN values that might be indicative of meat consumption.

Angioedema associated with thrombolysis for ischemic stroke: analysis of a case-control study.

Background: Bradykinin-mediated angioedema (AE) is a complication associated with thrombolysis for acute ischemic stroke. Risk factors are unknown and management is discussed.

Objectives: To clarify risk factors associated with bradykinin-mediated AE after thrombolysis for acute ischemic stroke.
