Methicillin-resistant Staphylococcus aureus

Methicillin-resistant Staphylococcus aureus (MRSA) (/ɛmɑːrɛseɪ/ or /ˈmɜːrsə/) is a bacterium responsible for several difficult-to-treat infections in humans. It is also called oxacillin-resistant Staphylococcus aureus (ORSA). MRSA is any strain of Staphylococcus aureus that has developed, through the process of natural selection, resistance to beta-lactam antibiotics, which include the penicillins (methicillin, dicloxacillin, nafcillin, oxacillin, etc.) and the cephalosporins. Strains unable to resist these antibiotics are classified as methicillin-sensitive Staphylococcus aureus, or MSSA. The evolution of such resistance does not cause the organism to be more intrinsically virulent than strains of S. aureus that have no antibiotic resistance, but resistance does make MRSA infection more difficult to treat with standard types of antibiotics and thus more dangerous.

MRSA is especially troublesome in hospitals, prisons, and nursing homes, where patients with open wounds, invasive devices, and weakened immune systems are at greater risk of nosocomial infection than the general public. MRSA began as a hospital-acquired infection, but has developed limited endemic status and is now sometimes community-acquired and livestock-acquired. The terms HA-MRSA (healthcare-associated MRSA), CA-MRSA (community-associated MRSA) and LA-MRSA (livestock-associated) reflect this distinction.

2-Ketoarginine methyltransferase

2-Ketoarginine methyltransferase (EC 2.1.1.243, mrsA (gene)) is an enzyme with system name S-adenosyl-L-methionine:5-carbamimidamido-2-oxopentanoate S-methyltransferase. This enzyme catalyses the following chemical reaction

The enzyme is involved in production of the rare amino acid 3-methylarginine.

Grab (ship)

A grab was a type of ship common on the Malabar Coast in the 18th and 19th Centuries. The name comes from "ghurāb" or "ghorāb", Arabic for raven, which word came into Marathi and Konkani as "gurab". The ghurāb was originally a galley, but the type evolved.

The grab combined an indigenous hull form with a pointed prow, with or without a bowsprit, combined with European rigging on two to three masts. A description from 1750 states that the grabs of Angria's fleet narrowed from the middle forward and instead of a bow had the prow of a Mediterranean galley, covered with a strong deck level with the main deck but separated from it by a bulkhead. The grab pitched violently when sailing against a head sea so the prow sides were open to that water would easily run off. On the main deck under the forecastle there were two 6 or 9-pounder guns pointing forward through port-holes cut in the bulkhead and firing over the prow. The grabs then had 6 or 9-pounder guns on their broadsides.

The vessel was generally of shallow draft, and broad in proportion to its length. Size could range between 150 to as much 500 tons (bm). The sail plan typically was that of a snow, or a brig.
