Parody of a public notice, dated June 20, 1828, reporting an assault on American Zionist, playwright, and editor Mordecai Manuel Noah by Elijah J. Roberts. In the text Noah petitions that Roberts "be bound by recognizance to be of good behavior and keep the peace, and to answer for the above assault, &c. at the next Court of General Sessions of the Peace . . . ." A vignette illustration portrays a diminutive figure of Roberts attacking a much larger Noah on the steps of New York's Park Theatre. A playbill on the wall behind them advertises "The Jew," "1 Act of the Hypocrite," and "End with the farce of The Liar." At this time Noah was editor of the "New York Enquirer."|Title appears as it is written on the item.|Published in: American political prints, 1766-1876 / Bernard F. Reilly. Boston : G.K.

These lessons concern the United States Constitution Article 1 concerning the establishment and purpose of the Legislative Branch of the three branches of the US Government.

In 1948, President Harry Truman took an early step towards civil rights reform by issuing Executive Order 9981, which eliminated racial segregation in the military. After World War II, African Americans ? then often called Negroes or "coloreds," began to mobilize against discrimination. They demanded an end to segregation and fought for equality in education, housing, and employment opportunities. The images in this topic show that by the 1960s, their struggle ? which began in the segregated South ? had reached California. As a number of photographs in this topic show, many Californians showed their support for Civil Rights activists and victims of racial discrimination in the South by holding marches, rallies, and demonstrations urging equality for African Americans. In one image three white children in San Francisco hold a sign in support of the four young black girls killed in the 1963 bombing of the 16th Street Baptist Church in Birmingham, Alabama. Photographs also show people in San Francisco boycotting Kress and Woolworth's department stores, sites of racial discrimination in the South. Documents shown here include a flyer urging the boycott of the stores; and a Western Union telegram sent in 1963, stating that Civil Rights activists Roy Wilkins and Medgar Evers were arrested attempting to picket Woolworth's in Jackson, Mississippi. Two photographs of memorials for slain civil rights leaders ? a march in honor Medgar Evers in 1963, in Los Angeles, and a memorial in the San Francisco Bay Area for Martin Luther King, Jr., in 1968 ? show racially mixed crowds in attendance. But not all Californians sympathized with the Civil Rights movement. Images of racial hatred and prejudice are reflected in the photograph of an African American woman holding a rock that had been thrown through an office window, and Klu Klux Klan graffiti spray-painted on a home. Various groups formed to fight in the struggle for equal rights. The National Association for the Advancement of Colored People (NAACP), formed in 1909, entered a new phase during this period, leading in the organized struggle for civil rights. An example of how the NAACP communicated about events is reflected in a letter from the Alameda County branch of the NAACP on June 13, 1950, which reported segregation on the Southern Pacific Railroad trains leaving Los Angeles. A flyer promoting the boycott of California grapes exemplifies NAACP support for other rights movements, in this case the United Farm Workers. Other flyers urged Californians to fight sharecropper wages and "Keep Mississippi Out of California." Groups such as the Congress of Racial Equality (CORE) and student groups also protested segregation and incidents of racial discrimination in the South. Several important African American leaders ? including Martin Luther King, Jr., Malcolm X, Thurgood Marshall, and Ralph Abernathy ? all came to California, as documented by photographs included here. Sometimes, the price of fighting for social justice was high. Two images capture events held for leaders in the social justice movement who were assassinated: the 1963 memorial march in Los Angeles for civil rights leader Medgar Evers; and a crowd attending a Martin Luther King, Jr., Memorial Rally in honor of the slain civil rights leader.

The images in this collection are drawn from the New-York Historical Society's rich archival collections that document the Civil War. They include recruiting posters for New York City regiments of volunteers, stereographic views documenting the mustering of soldiers and of popular support for the Union in New York City, photography showing the war's impact, both in the North and South, and drawings and writings by ordinary soldiers on both sides.

Conflict between abolition and slavery marked the 1850s, preceding the election of 1860 and the attack on Fort Sumter that started the Civil War. The Kansas-Nebraska Act, Dred Scott, Harriet Beecher Stowe, John Brown, and secession in maps, newspapers, political cartoons and song sheets.

"The Civil War in Art: Teaching and Learning through Chicago Collections" is intended to help teachers and students learn about the Civil War—its causes and effects—and connect to the issues, events, and people of the era through works of art.

Web resource explores the Civil War through over 120 zoomable images from Chicago collections, with text and questions for students. The site presents essays about: The Civil War and American visual culture, the causes of the war, the military experience, emancipation and the meaning of freedom, the northern homefront, Lincoln, and remembering the war.

Other resources include classroom projects for teacher use, an in-depth glossary of art and historical terms, and links to additional Civil War resources.

A Ciênsação foi criado com o apoio da UNESCO Brasil para promover uma cultura de experimentos curtos, claros, focados e realizados pelos alunos em sala de aula. Por meio de atividades “mão na massa”, os alunos reforçarão habilidades, competências essenciais e vivenciarão o fascínio pela pesquisa científica.

Estas atividades de pesquisa foram concebidas especificamente para promover o pensamento crítico, a capacidade analítica e o trabalho em equipe na sala de aula. Cada experimento vem acompanhado de perguntas, a fim de dar início a uma discussão. Em vez de apenas ilustrar conceitos científicos ou fenômenos naturais, esses experimentos foram desenvolvidos para ensinar ciência como uma atividade, uma arte fascinante da qual os alunos desejarão se apropriar.

Four vignette cartoon shows Brother Jonathan kicking the confederacy, Napoleon III, and Emperor Maximillian, represented by animals, with his "iron-clad" boots. In the next vignette, Brother Jonathan fills the feed dish of the American eagle with yellow pills, from which the bird produces specie, "green backs." In the third vignette, men ride horses which have the heads of Abraham Lincoln, John Charles Fremont, Pomeroy and Gilbert. The journalist, Horace Greeley, is thrown from his mount. They head toward Richmond. In the fourth vignette, titled, "The Yankee rooster converting English blockade runners into iron-clads and monitors," the rooster consumes English blockade runners and turns them into iron-clads and monitors through the process of elimination.|Lithograph by G.W.

Another Whig campaign satire, picturing incumbent Martin Van Buren and his Democratic advisers or "Kitchen Cabinet" routed by Whig candidate William Henry Harrison. In a domestic kitchen Harrison, dressed as a scullery maid, raises a "buttermilk dasher" against a party of fleeing Democrats. The fugitives are (left to right, standing): Secretary of War Joel Poinsett, Postmaster General Amos Kendall, Washington "Globe" editor Francis Preston Blair (arms outstretched, looking left), Secretary of State John Forsyth, John Calhoun, Levi Woodbury, and Van Buren. Thomas Hart Benton (left) and Alabama Representative Dixon H. Lewis, a States Rights Democrat, have fallen to the floor. Harrison: "Gentlemen as you don't like hard Cider I will give you a taste of the Buttermilk Dasher." Van Buren: "This is worse than the Rebellion in Vermount!" Poinsett: "If you had followed my advice we would have had by this time our Standing Army of 200,000 men." Blair: "I shall leave the Globe!" Forsyth: "I shall never be Vice President." Calhoun: "I am for the South direct." Woodbury: "I can issue no more Treasury Notes!" On the far left a bespectacled man with plaited hair (Pennsylvania Democratic congressman David Petrikin) holds up his hand and says, "I object." The man lamenting his lost hopes for the vice presidency has been previously identified as Alabama Senator William Smith. Yet comparison of the likeness here with Charles Fenderich's 1840 lithographed portrait of Secretary of State John Forsyth confirms identification of the man as that cabinet member. The print is most probably by Napoleon Sarony, showing the same distinctive, patterned cross-hatching and broad crayon-work as his "The New Era or the Effects of a Standing Army "(no. 1840-3). "Clar de Kitchen" was the title of a popular dance song of Negro minstrel comic T.D. Rice.|Entered . . . 1840 by H.R. Robinson.|Printed & published by H.R.

"Overexpression of the protein EGFR is associated with various cancers. That’s made EGFR inhibitors a promising class of anti-cancer drugs. Although EGFR targeting of colorectal cancer is well understood, some patients respond unexpectedly well. A pair of studies have studied why cancers with the KRAS G13D mutation respond well to EGFR inhibition. They propose different mechanisms to explain the beneficial response. One study suggests that a tumor-suppressing protein known as NF1 decreases the KRAS activity that drives cancer growth. The other suggests that NF1 actually decreases NRAS and HRAS but not KRAS. Now, a new study appears to provide some clarity in the matter. Using antibodies specific to each RAS protein, researchers showed that an abundance of NF1 downregulates the proteins NRAS and HRAS in colorectal cancer cells, with no effect on KRAS..."

"Cardiac fibrosis, or scarring of heart tissue, is a common finding in many disorders of the heart, including myocardial infarction, hypertension, and cardiac hypertrophy. A key step in this form of scarring is the transformation of fibroblasts, cells that provide structural, electrical, and chemical support into myofibroblasts, more muscle-like cells expressed only in stressed or failing hearts. A new review explores the important role played by noncoding RNAs in this transformation. Noncoding RNAs, studies are showing, regulate fibrotic scarring through the TGF-β and WNT signaling pathways. TGF-β signaling participates in a variety of heart-related processes, including cardiac repair, hypertrophy, fibrotic remodeling, and fibroblast activation. WNT signaling, meanwhile, is implicated in the pathogenesis of many diseases. Crosstalk between the TGF-β and WNT pathways could be responsible for the transcription of genes that promote fibrosis..."
