IgG4-related disease (IgG4-RD), formerly known as IgG4-related systemic disease, is a chronic inflammatory condition characterized by tissue infiltration with lymphocytes and IgG4-secreting plasma cells, various degrees of fibrosis (scarring) and a usually prompt response to oral steroids. In approximately 51–70% of people with this disease, serum IgG4 concentrations are elevated during an acute phase. It is a relapsing–remitting disease associated with a tendency to mass forming, tissue-destructive lesions in multiple sites, with a characteristic histopathological appearance in whichever site is involved. Inflammation and the deposition of connective tissue in affected anatomical sites can lead to organ dysfunction, organ failure, or even death if not treated. Early detection is important to avoid organ damage and potentially serious complications. Treatment is recommended in all symptomatic cases of IgG4-RD and also in asymptomatic IgG4-RD involving certain anatomical sites.

Pacific Southwest Airlines (PSA) Flight 182 was a Boeing 727-214 commercial airliner, registration N533PS, that collided with a private Cessna 172 light aircraft, registration N7711G, over San Diego, California, at 9:01 am on Monday, September 25, 1978. It was Pacific Southwest Airlines' first fatal accident, and the deadliest air disaster in California history. Both aircraft crashed into North Park, a San Diego neighborhood. Flight 182 impacted just north of the intersection of Dwight and Nile streets, killing all 135 people aboard the aircraft and seven people on the ground in houses, including two children. The Cessna impacted Polk Avenue between 32nd and Iowa streets, killing the two on board. Nine others on the ground were injured and twenty-two homes were destroyed or damaged by the impact and debris.

Benjamin Rathbun (December 1, 1790 – July 20, 1873) was an entrepreneur from Buffalo, New York. He was born in the area of Westford, Connecticut. His family had settled in New York from Connecticut. Before entering real estate, his Eagle Tavern served those who were travelling between Buffalo and Albany. In the 19th-century, he built out the city's central business district and many other areas of the city, totaling hundreds of buildings. These included a fourteen-floor warehouse, dozens of low-rise buildings, a hotel, and nearly three dozen private dwellings. His investors were looking to capitalize on the explosive growth of Buffalo after the Erie Canal was finished. Rathbun drew inspiration from Alexander Hamilton and implemented vertical integration into his business model. He began to operate a quarry, brickyards, and machine shops. He would also hire his own architects, shipping personnel, and other tradesmen to help see his projects to completion. By 1836, Rathbun's projects under construction had a collective value of $5.5 million ($130 million in 2020). His reputation led to him opening his own bank, with banknotes displaying his signature as "B. Rathbun". Rathbun's plans for more projects, including a Buffalo Exchange building, were halted prior to the Panic of 1837—he was later jailed for forged endorsements in 1836. This crisis led to mass unemployment in the lodging, education and banking sectors, which relied on his company's fortunes to succeed. Rathbun died on July 20, 1873. The vast majority of Rathbun's buildings have been destroyed or demolished in the years since his period of activity. The sole exception is the Title Guarantee Building at the corner of Franklin and West Eagle Streets, which he built in 1833 as home of the First Unitarian Church, but was heavily altered by architect Franklin W. Caulkins upon its conversion to offices in the 1880s.

An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions. The electrochemical cells which generate an electric current are called voltaic cells or galvanic cells and those that generate chemical reactions, via electrolysis for example, are called electrolytic cells. A common example of a galvanic cell is a standard 1.5 volt meant for consumer use. A battery consists of one or more cells, connected in parallel, series or series-and-parallel pattern.
