After tokenization with the ChemXSeer chemical tokenizer which is based on Lucene StandardAnalyzer[20], each token is assigned to one of the following classes: {B, I, O}, where B denotes a start of chemical entity, I denotes a continuation from the previous entity, and O for everything else.
This series represents a continuation of efforts following on from previous studies of C-3 benzoic acid-substituted betulinic acid derivatives as HIV-1 maturation inhibitors (MIs) that were explored in the context of C-28 amide substituents.
Before switching to the planned subsequent line of therapy, the following criteria must be fulfilled: at least one reason to discontinue previous line of therapy, patient general conditions compatible with treatment continuation (at investigator's discretion), and acceptable residual toxicities from previous line of therapy.

Despite large numbers of killings, the targets often escaped, while innocents were killed in their stead.
This was in continuation of the basics of programming with python that had already been covered during the open labs sessions from previous semester.
This study is a continuation of previous work designed to assess the effect of elevated-pH bioleaching on a low-grade ultramafic nickel sulphide ore from Manitoba, Canada.
This is a continuation of previous work, which was designed to assess the technical feasibility of applying elevated-pH bioleaching to this same ore from Manitoba, Canada.
