[Stanford Type A Acute Aortic Dissection with Acute Myocardial Infarction due to Compression of Left Main Coronary Artery:Report of a Case].

A 58-year-old man was admitted to our institution with sudden onset of hypotension and acute ischemia of left lower extremity. Electrocardiography showed ST segment elevation in leads V1~V6 and a transthoracic echocardiogram revealed antero-septal wall hypokinesis. He was given a diagnosis of acute myocardial infarction caused by left main coronary artery compression due to acute aortic dissection by enhanced computed tomography.

Seasonal and annual fluctuations of deer populations estimated by a Bayesian state-space model.

Deer overabundance is a contributing factor in the degradation of plant communities and ecosystems worldwide. The management and conservation of the deer-affected ecosystems requires us to urgently grasp deer population trends and to identify the factors that affect them. In this study, we developed a Bayesian state-space model to estimate the population dynamics of sika deer (Cervus nippon) in a cool-temperate forest in Japan, where wolves (Canis lupus hodophilax) are extinct.
