Triterpenoids

“…189 The anti-HIV activity of betulinic acid and its derivatives have been covered in a short review. 190 Officinatrione 446, with an unusual 17,18-secolupane skeleton, was isolated from Taraxacum officinale where it occurs with four intact lupanes 447 -450.…”

A preliminary Monte Carlo study for the treatment head of a carbon-ion radiotherapy facility using TOPAS

“…Over the past 30 years, ion beam radiotherapy using particles like proton, helium, carbon ions has been gradually and slowly increasingly in popularity in radiation oncology [1][2][3].The inverted depth dose profile ⎯the increase of dose along the penetration depth (the Bragg Peak) and a sharp drop after the Bragg Peak ⎯ make ion beams an ideal tool for treatment of the deepseated tumours [1][2][3][4][5][6][7]. For carbon ions, the excellent dose profile is further boosted by an additional increase in the relative biological effectiveness (RBE) along the depth till the end of the particle range [2-4, 6, 8].Because of the distinguished physical and biological properties, carbon ion radiotherapy (CIRT) has become a unique research focus around the world.…”

In China, after almost 10 years of research about heavy ion therapy at the Institute of Modern Physics (IMP), Chinese Academy of Sciences (CAS), sophisticated and advanced techniques of beam delivery and treatment planning system have been established [5,6]. Since 2006, a total of 213 patients have been treated using carbon ions and most of them are observed with impressive therapeutic effect [5,6].…”

Since 2006, a total of 213 patients have been treated using carbon ions and most of them are observed with impressive therapeutic effect [5,6]. Encouraged by the superior clinical results, two dedicated heavy-ion therapy facilities are now under construction in Lanzhou and Wuwei, China, respectively.…”

Isolated Attosecond Pulse Generation in a 800 nm Laser Field by Adding a Terahertz (THz) Pulse

“…The generation of attosecond pulse leads the study of ultrafast nonlinear optics into a new territory for observing the relaxation processes and the motion of electrons inside the atom or molecule [7]. Therefore, a lot of researches have been taken for characteristic of the high-order harmonic emission, and many efficient methods have been suggested [8][9][10][11][12].…”
