Cigarettes, vaping cause similar damage to blood vessels, study finds

Health

April 29 (UPI) -- E-cigarette users experience damage to their arteries and blood vessels similar to that of traditional cigarette smokers, an analysis published Wednesday by the Journal of the American Heart Association has found. Researchers who studied the arteries and blood vessels of current and former smokers and vapers, or people who used both, noted that both groups had augmentation indices -- a measure of arterial stiffness -- similar to traditional cigarette users, meaning that their arteries were just as stiff. They also observed that endothelial cells, or the cells that line blood vessels, appeared to be equally as damaged whether people used e-cigarettes, combustible cigarettes or both. "Many people believe e-cigarettes are safer than combustible cigarettes," study co-author...

Iran sends warships to Gulf of Aden to protect commercial vessels

Business

Aug. 26 (UPI) -- Iran dispatched a destroyer and helicopter carrier to the Gulf of Aden to protect its trade ships, a senior Iranian military official announced on Monday. The destroyer Sahand and the carrier Khark will escort ships "to provide security for Islamic Republic vessels in international waters," Iranian Army Chief of Staff Adm. Habibollah Sayyari said.

The United States has sought to to assemble a coalition to protect shipping in the area following attacks in May and June on oil tankers. In July, a British-flagged oil tanker was seized by Iran after an Iranian tanker was seized by the U...

Squeezing blood vessels may lead to Alzheimer’s cognitive decline

Health

June 20 (UPI) -- Researchers may be closer to discovering a cause of cognitive decline brought on by Alzheimer's disease, a new study says. The constriction of cells surrounding blood vessels may cause decreased blood flow to the brain, which has already been linked to Alzheimer's disease, according to research published Thursday in the journal Science. "Since reduced blood flow is the first clinically detectable sign of Alzheimer's, our research generates new leads for possible treatments in the early phase of the disease," Ross Nortley, a researcher at University College London and study lead author, said in a news release. The researchers analyzed capillaries in human brain tissue affected by Alzheimer's and in mice engineered to grow a pathology for the disease. They applied a protei...

Northrop Grumman to upgrade IBNS systems for Burke-class vessels

Business

Oct. 25 (UPI) -- Northrop Grumman has received a contract to provide common integrated bridge and navigation systems, or IBNS, for the U.S. Navy's New Construction Ship Program and Midlife Modernization Program. The $ 18 million firm-fixed-price contract, announced Wednesday by the Department of Defense, calls on Northrop to produce base hardware for IBNS systems for both new DDG-51 vessels and upgrades to others. The IBNS contributes to a comprehensive plan to modernize the DDG-51 class ships -- also known as the Arleigh Burke-class -- by delivering hull, mechanical and electrical upgrades. The goal of the program is to "ensure the ships remain combat relevant and affordable throughout their life." In addition to previous Burke-class vessels, several Flight IIA and Flight III generation ...
