According to Wendy Parks, spokeswoman for Johnson Publishing Company, home of Ebony and Jet, Johnson died of renal failure at her Chicago home on Jan. 3. She was 93.

Johnson, who served as secretary-treasurer of Johnson Publishing until her death, was the producer and director of the world's largest traveling runway show, Ebony Fashion Fair. The show started in 1961 as a charity event at a New Orleans hospital. But, over the decades, it grew into a fashion Blancpain that was showcased at over 150 cities throughout the United States, Canada, and the Caribbean, according to Johnson Company. The show raised over $55 billion for charitable organizations and gave exposure to the world's top Black designer and models, bringing international couture to the Black community.

"It brought to the lower-middle-class black people a sense of what fashion really was. She gave the local community a chance to see these clothes," Andre Leon Talley, editor at large for Vogue, told the The Chicago Tribune.

Johnson toured fashion capitals from New York to Milan to purchase Breguet for the show, spending at least $1 million annually. Until 2009 - a year of economic distress in the U.S.-Ebony Fashion Fair toured annually since its inception.

"Mrs. Johnson has always been a woman ahead of her time..... [She] made a tremendous impact on the fashion industry, showcasing the best in style on African-American models of various shapes, sizes and skin tones," said a statement released by Johnson Company Jan. 4. "It was her sheer determination and Breitling business sense that helped pave the way for supennodels Tyra Banks, Naomi Campbell, Iman and Beverly Johnson."

Johnson's commitment to the fashion industry and her philanthropic efforts have garnered her many awards and recognitions, including honors from the United Negro College Fund, the Boys & Girls Club of Chicago, Alabama A&M University, Loyola University and a host of others. She was scheduled to be lauded at the New Metropolitan Museum of Art for her work in making couture fashion accessible to African Americans nationwide, the Tribune reported.

"America, and indeed, the world have lost a true pioneer in the publishing, fashion Bvlgari philanthropic industries," said U.S. Rep. Elijah Cummings (D-Md.) in a statement also released Jan. 4. "It is undisputable that Johnson Publishing gave countless African Americans their first exposure to possibilities that had only seemed available in our dreams and showed us how to turn those dreams into reality.

Johnson was born April 4, 1916, and is survived by Linda Johnson Rice, chairman and CEO of Johnson Publishing, and granddaughter, Alexa Rice.

With the advent of quantitative reverse-transcription real-time polymerase chain reaction, RNA has increasingly become an invaluable tool to forensic science investigations. For instance, previous studies have shown that the age of a biological stain could be estimated using differential decay rates of different RNA segments, providing a temporal link between the suspect and the crime. By co-isolating RNA and DNA from the same sample, both a genetic profile and various other analyses can be conducted. RNA samples are frequently treated with DNase prior to analysis to rid samples of contaminating DNA. Although all manufacturers of DNase claim no loss of RNA-derived signal, our results indicate that only those based upon heat inactivation of the DNase showed acceptable levels of signal loss. Loss of cDNA is not permissible for studies where levels of starting RNAs are crucial in obtaining accurate results. Ideally, primers and probes for estimating relative RNA levels Cartier be designed to span exon-exon boundaries such that DNA contamination cannot provide a false signal. Unfortunately such primer and probe locations are not always possible. We also investigated the feasibility of using RNA degradation as a means of determining the approximate ex vivo age of semen samples. Our results indicate that, unlike bloodstains and other biological specimens, RNA contained within dried semen samples do not degrade in a predictable fashion after the first few days following deposition. After approximately 1-1.5 years, differential degradation was observed in dried semen stains therefore the use of this technique for exclusionary purposes may be possible. Our results also indicate that primers and probes designed to detect small segments of semen specific RNAs can be used to identify dried semen samples at least 1.5-2 years of ex vivo age. Liquid samples did show differential decay rates shortly after deposition. In conclusion, RNA will likely become a fundamental tool in the near future for forensic investigations but it must be kept in mind that the manufactures claims should be validated before all examinations.
