Two-body B meson decays to eta and eta('): observation of B --> eta K*.

In a sample of 19 x 10(6) produced B mesons, we have observed the decays B-->eta K(*) and improved our previous measurements of B-->eta'K. The branching fractions we measure for these decay modes are B(B+-->eta K(*+)) = (26.4(+9.

Observation of B --> K(+/-) pi(0) and B --> (K)0 pi(0), and evidence for B --> pi(+)pi(-).

We have studied charmless hadronic decays of B mesons into two-body final states with kaons and pions and observe three new processes with the following branching fractions: beta(B-->pi(+)pi(-)) = (4.3(+1. 6)(-1.

Heavy metals in fish from the Barents Sea (summer 1994).

To assess the significance of metals in biota of the Barents Sea, preliminary information is presented for the concentrations of Cd, Pb, Hg, Ni, Cu and Zn in liver and muscle tissues of 15 marine fish species collected in the summer of 1994. Lead and Ni concentrations are below limits of detection (< 0.3 and 1.

[Results of the combined treatment of cancer of the cardial region of the stomach (a cooperative, randomized study)].

Immediate and long-term results of treatment of cancer of the proximal part of the stomach were compared in two groups of patients: (1) surgery and (2) combined treatment (preoperative Co-60 teletherapy + radical surgery). The patients were randomly assigned to the treatment schedules. The study was cooperative.

[Successful results in the interferon therapy of autoimmune disease in NZB/W strain mice].

The experiment used 50 female NZB/W mice divided into 2 groups of 25 animals each. Beginning at the age of 3 weeks and up to 1 year the animals of the experimental group were given once in 2 weeks 104 U/injection of mouse interferon intraperitoneally; the animals of the control group received physiological saline according to the same schedule. At the age of 3 months and subsequently at 6-week intervals up to 1 year mice of the two groups were examined for blood serum antibodies to native DNA and double-stranded RNA.
