[Bi-weekly docetaxel and doxifluridine combination therapy in pretreated patients with unresectable and/or advanced gastric cancer].

We report an investigation of the therapeutic efficacy and safety of combination chemotherapy with docetaxel (DOC) and doxifluridine (5'-DFUR) administered as second-line or third-line chemotherapy in 23 cases of unresectable and/or advanced gastric cancer. Treatment consisted of intravenous DOC (40mg/m/2) on day 1 and 15, and oral 5'-DFUR (600mg/body) on days 1 to 28 every 4 weeks. The response rate for its antitumor efficacy was 17.

Inhibition of the 53BP2S-mediated apoptosis by nuclear factor kappaB and Bcl-2 family proteins.

The p53 binding protein 2 (53BP2) has been identified independently as the interacting protein to p53, Bcl-2, and p65 subunit of nuclear factor kappaB (NF-kappaB). It was demonstrated that over-expression of 53BP2 (renamed as 53BP2S) induces apoptotic cell death. In this study we explored the effect of NF-kappaB activation elicited by a physiological NF-kappaB inducer, interleukin-1beta (IL-1beta), and anti-apoptotic Bcl-2 family proteins on the 53BP2S-mediated apoptosis.

53BP2 induces apoptosis through the mitochondrial death pathway.

The p53 binding protein 2 (53BP2) has been identified as the interacting protein to p53, Bcl-2, and p65 subunit of nuclear factor kappaB (NF-kappaB). The TP53BP2 gene encodes two splicing variants, 53BP2S and 53BP2L, previously known as apoptosis stimulating protein 2 of p53 (ASPP2). We found that these 53BP2 proteins are located predominantly in the cytoplasm and induce apoptosis as demonstrated by cleavage of poly ADP ribose polymerase (PARP) and annexin V staining.

Efficacy of plastic tube stents without side holes for middle and lower biliary strictures.

Background: Although biliary expandable metallic stents (EMS) improve patency, they are unsuitable for primary biliary stenting. Although plastic tube stents without side holes (PWOS) are also reported to prolong patency, their efficacy remains controversial.

Goals: To evaluate clinical utility and relative advantages, we reviewed clinical results of three types of stents: plastic tube stents with side holes (PS), PWOS, and EMS.
