GENETIC BASIS OF THE EARLY HEADING OF HIGH-LATITUDE WEEDY RICE

Genetic basis of the early heading of high-latitude weedy rice

Japonica rice (Oryza sativa L.) is an important staple food in high-latitude regions and is widely distributed in northern China, Japan, Korea, and Europe.However, the genetic diversity of japonica rice is relatively narrow and poorly adapted.Weedy rice (Oryza sativa f.spontanea) is a semi-domesticated rice.Its headings are earlier than the accompa

Low flow low gradient aortic stenosis: clinical pathways

Aortic stenosis patients with severe LV dysfunction and low cardiac output present with Rear Stabilizer relatively low transvalvular gradients.It is difficult to distinguish them from aortic sclerosis and LV dysfunction with low cardiac output.The former condition is severe AS with LV dysfunction and latter is primarily a contractile dysfunction.Do
