We review the histopathology results from seven long-term studies, five using TBI and two using busulfan.In eukaryotes three DNA polymerases (Pols), α, δ, and ε, are tasked with bulk DNA synthesis of nascent strands during genome duplication. Most evidence supports a model where Pol α initiates DNA synthesis before Pol ε and Pol δ replicate the leading and lagging strands, respectively. However, a number of recent reports, enabled by advances in biochemical and genetic techniques, have highlighted emerging roles for Pol δ in all stages of leading-strand synthesis; initiation, elongation, and termination, as well as fork restart. By focusing on these studies, this review provides an updated perspective on the division of labor between the replicative polymerases during DNA replication.A pair of new isocoumarin derivative enantiomers, (S)-(-)-3-(3,3-dichloro-2-hydroxy-propyl)-4-chlorine-6,8-dihydroxy-isochromen-1- one (1a) and (R)-(+)-3-(3,3-dichloro-2-hydroxy-propyl)-4-chlorine-6,8-dihydroxy-isochromen-1- one (1 b), as well as seven known compounds (2-8) were isolated from Ludwigia hyssopifolia. Compounds 1a and 1 b were confirmed to be a pair of enantiomers by chiral HPLC-CD analysis, and the structure of compound 1 was determined by spectroscopic analyses including extensive 1 D (1H NMR, 13C NMR) and 2 D NMR spectra (COSY, HSQC and HMBC) and MS data. And the absolute configurations of compounds 1a and 1 b were determined by the quantum chemical ECD calculations. Compounds 2-8 are firstly reported from this plant. In the in vitro assays, compounds 5 and 8 can inhibit human laryngeal cancer Hep-2 cell line growth in a dose- and time-dependent manner. In addition, compounds 2 and 4 have effects on increasing glucose uptake in vitro. Compound 2 showed a strong glucose uptake in L6 cells, wi
