Reducing the frequency at which a patient must take a medication can improve patient adherence. Kirtane et al. developed an ingestible gastric resident dosage form that releases the contraceptive levonorgestrel. Levonorgestrel was detected in the serum of…
WHO, CDC data shows measles cases up 30 percent globally, with the disease killing more than 140,000 people worldwide in 2018, despite the availability of a vaccine. “That anyone should die from measles... is a collective failure which must be addressed”.

超级火山喷发是否会导致人类毁灭?
在意大利那不勒斯湾,有迹象显示欧洲最臭名昭著的火山巨人正在从长眠中苏醒过来。 坎皮佛莱格瑞(Campi Flegrei),一个也可翻译为"燃烧场"的火山,是一座超级火山。它由数十万年前形成的广泛而复杂的地下网络组成,从那不勒斯郊区延伸到地中海下方。约有50万人生活在坎皮佛莱格瑞的七英里长的火山口,该火山口由20万、3万9千、3万5千和12万年前的大规模火山爆发形成。 过去500年来,坎皮佛莱格瑞相当平静。自1538年以来一直没有爆发,一个相对较小的喷发导致形成了一座"新山" ——诺沃山(Monte Nu…
