HOUSTON (AP) _ Dr. Alando ``Jay'' Jones Ballantyne, who pioneered new surgical methods for removing cancer tumors from the neck, died Monday of complications from hepatitis. He was 80.

Ballantyne had worked at the University of Texas' M.D. Anderson Cancer Center since 1947, and was professor of surgery from 1974 until his retirement in 1990.

Ballantyne is credited with being the first surgeon in the United States to pioneer modified radical neck dissection.

Until the 1950s, surgical removal of cancer in the neck's lymph nodes often left the patient with reduced shoulder movement, scarring and tissue loss. Ballantyne perfected a technique that preserved shoulder movement.

Alberto Sartoris

LAUSANNE, Switzerland (AP) _ Alberto Sartoris, a pioneer of avant-garde architecture, died Sunday. He was 97.

A contemporary of Le Corbusier and Walter Gropius, much of Sartoris' early work was rejected by building regulators or radically changed by clients. He told an interviewer two years ago that he had designed more than 800 projects in his life, but that only 50 were actually built.

Sartoris lectured in the United States, Spain and Italy and published a number of works, most notably three editions of the ``Elements of Functional Architecture'' and the three-volume ``Encyclopedia of the New Architecture.'' Both were written in French.

Schoenbohm also founded the Crippled Children's School in Jamestown, N.D., and served as the school's executive director for a decade from 1938-1948.

Arkady Shevchenko

BETHESDA, Md. (AP) _ Arkady Shevchenko, a top Soviet diplomat whose defection 20 years ago created an international sensation, died Feb. 28 from an apparent heart attack. He was 67.

Shevchenko was undersecretary general of the United Nations in 1975, when he began working secretly for the Central Intelligence Agency. Before taking his U.N. post, he was secretary in Moscow to Soviet foreign minister Andrei Gromyko.

Considered the CIA's catch of the decade, he defected in April 1978. When he announced he would not go home, Soviet officials claimed he was being held under duress and tried to get him to return to Moscow.

Following his defection, Shevchenko wrote the best-selling book, ``Breaking with Moscow,'' commanded lucrative lecture fees and lived in an affluent neighborhood.

His book said his CIA handlers proved insensitive to the trauma of defection. And the KGB whisked his wife back to Moscow where she reportedly committed suicide by taking an overdose of sleeping pills.

When the Soviet Union dissolved, Shevchenko disappeared from public view and spent his remaining years as a virtual recluse.
