We further show that H2S release from this compound protects H9c2 rat cardiomyoblasts from an in vitro model of ischemic reperfusion injury. These results validate the utility of redox゛ctivated metal complexes as hypoxia﹕elective H2S‐releasing agents for use as tools to study the role of this...
Identify one element from the periodic table and explain its role in the human body (either alone or as part of a molecule). Is it something we need to survive? If so, is it found in any foods we eat? Distinguish between an element and a compound and give an example of e...
Give the formula of the compound formed from strontium and fluorine. Is bismuth most likely to be found in nature as an oxide, a sulfide, or a free metal (uncombined)? Explain. A certain element is a metalloid that forms an acidic oxide with the formula R_{2}O_{5}. Identify t...
Most plants use C3 photosynthesis, according to the photosynthesis research projectRealizing Increased Photosynthetic Efficiency (RIPE). C3 plants include cereals (wheat and rice), cotton, potatoes and soybeans. This process is named for the three-carbon compound 3-PGA that it uses during the Calvin...
Carbon monoxide (chemical formula CO) is a colorless, odorless, flammable and highly toxic gas. It is a major product of the incomplete combustion of carbon and carbon-containing compounds. Oxygen is a nonmetallic element constituting 21 percent of the atmosphere by volume. Oxygen is also found...
Element/compound distinction (单质/化合物 区分). One of the most strongly emphasized aspects of environmental analysis involves the distinction between a chemical element and the chemical compound in which that element exists. 在环境分析中最重点强调的部分中的一个就是要对化学元素单质及有此元素的化学...

1. A process for producing a photocatalyst which comprises a capsule structure comprising a cadmium compound shell and a void, said process comprises bubbling H2S gas into a liquid to which particles of cadmium oxide have been added. 2. The process according to claim 1, which comprises supportin...
Correspondingly, the expression levels of the principle genes involved in JA biosynthesis (LOX, AOS and AOC), which are located in a companion cell-sieve element complex55,56, were up-regulated after heat shock treatment (Figs 1 and 2). Based on these findings, it is possible that heat ...
