Tadalafil is an oral drug that is used for treating impotence (the inability to attain or maintain a penile erection) and benign prostatic hyperplasia (BPH). It is in a class of drugs called phosphodiesterase-5 (PDE5) inhibitors that also includes sildenafil (Viagra) and vardenafil (Levitra). Erection of the penis is caused by the filling of the penis with blood. Filling occurs because the blood vessels that bring blood to the penis increase in size and deliver more blood to the penis, and, at the same time, the blood vessels that take blood away from the penis decrease in size and remove less blood from the penis. Sexual stimulation that leads to an erection causes the production and release of nitric oxide in the penis. The nitric oxide causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP). It is cGMP that is primarily responsible for increasing and decreasing the size of blood vessels carrying blood to and from the penis, respectively, and causing an erection. When the cGMP is destroyed by another enzyme, phosphodiesterase-5, the blood vessels return to their normal size, blood leaves the penis, and the erection ends. Tadalafil prevents phosphodiesterase-5 from destroying cGMP so that cGMP stays around longer. The persistence of cGMP leads to a more prolonged engorgement of the penis with blood.
Hybrid Rice: Chuan Xiang You 2
1. Excellent agronomic traits This variety belongs to three-line hybrid Japonica rice. The whole growth period of mid-season rice cultivation in the upper reaches of the Yangtze River was 157.4 days, which was 4.1 days longer than that of the control Shanyou 63; the whole growing period of the middle-lower reaches of the Yangtze River was 137.7 days. The comparison of Shuyou 63 was ripe for 2.3 days. The leaf shape is good, the leaf color is dark green, the growth is flourishing, the panicle type is large, and the color is good in the later period. The average plant height was 114.4 cm. The number of effective panicles per acre was 168,000 panicles, the panicle length was 24.6 cm, and the panicles were 181 grains per panicle and the grain weight was 29.1 g. Second, the rice is of high quality, with a Thai rice flavor Chuan Xiangyou 2 rice grain transparent, shiny, with Thai rice flavor, good palatability. According to the Ministry of Agriculture's Rice Quality Supervision, Inspection and Testing Center, the nine key indicators of Chuanxiangyou No. 2 reached the first-grade standard for high quality rice. Rice is medium in softness and hardness, with rich aromas and good palatability. 3. High yield and wide adaptability In 2001, regional trials in Sichuan Province increased production by 4.11% compared with the control Shanyou 63, and the production test in the same year increased 7.8% over the control Shanyou 63. In 2001, it took part in the national regional test, with an average yield of 632.4 kilograms per mu, an increase of 4.24% over the control Shanyou 63, reaching a very significant level. In 2002, the national district experiment had an average yield of 587.9 kilograms, an increase of 6.89% compared with the control Shanyou 63, reaching a very significant level. It is suitable for midseason rice cultivation in a season.
