Carbonic Anhydrase 4
Carbonic anhydrase 4 is an enzyme that in humans is encoded by the ''CA4'' gene In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protei .... Function Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. They show extensive diversity in tissue distribution and in their subcellular localization. CA IV is a glycosylphosphatidyl-inositol-anchored membrane isozyme expressed on the luminal surfaces of pulmonary (and certain other) capillaries and of proximal renal tubules. Its exact function is not known, howev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hippocampus Proper
The hippocampal subfields are four subfields CA1, CA2, CA3, and CA4 that make up the structure of the hippocampus. Regions described in the hippocampus are the head, body, and tail, and other hippocampal subfields include the dentate gyrus, the presubiculum, and the subiculum. The CA subfields use the initials of Hippocampus#Name, cornu ammonis, an earlier name of the hippocampus. Structure There are four hippocampal subfields, in the hippocampus proper which form a neural circuit called the trisynaptic circuit. CA1 CA1 is the first region in the hippocampal circuit, from which a significant output pathway goes to layer V of the entorhinal cortex. The main output of CA1 is to the subiculum. CA2 CA2 is a small region located between CA1 and CA3. It receives some input from layer II of the entorhinal cortex via the perforant path. Its pyramidal cells are more like those in CA3 than those in CA1. It is often ignored due to its small size. CA3 CA3 receives input from the mossy fi ...

Hippocampus
The hippocampus (: hippocampi; via Latin from Ancient Greek, Greek , 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus, and the subiculum are components of the hippocampal formation located in the limbic system. The hippocampus plays important roles in the Memory consolidation, consolidation of information from short-term memory to long-term memory, and in spatial memory that enables Navigation#Navigation in spatial cognition, navigation. In humans, and other primates the hippocampus is located in the archicortex, one of the three regions of allocortex, in each cerebral hemisphere, hemisphere with direct neural projections to, and reciprocal indirect projections from the neocortex. The hippocampus, as the medial pallium, is a structure found in all vertebrates. In Alzheimer's disease (and other forms of dementia), the hippocampus is one of the first regions of th ...

CAC CA-4
The CA-4 Wackett Bomber and CA-11 Woomera were prototype twin-engine light bombers, including torpedo and dive-bombing capabilities, developed by Commonwealth Aircraft Corporation (CAC) in Australia, during World War II. While two prototypes were completed and flight tested by the Royal Australian Air Force (RAAF), was an order for the Woomera was cancelled before it went into production. Design and development Background In early 1939, the Australian Government ordered large numbers of Bristol Beaufort bombers, with major components to be built by its Department of Aircraft Production (DAP) in a variety of locations, including railway workshops, and in doing so it by-passed the local aircraft company, the Commonwealth Aircraft Corporation. CAC, under Sir Lawrence Wackett, began work on its own design, hoping to out-perform the Beaufort by building a machine that could serve as both a torpedo-bomber and dive bomber. To keep down weight, Wackett dispensed with traditional self-se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Pittsburgh (CA-4)
The second USS ''Pennsylvania'' (ACR/CA-4), also referred to as Armored Cruiser No. 4, and later renamed ''Pittsburgh'', was a United States Navy armored cruiser, the lead ship of her class. She was originally assigned the name ''Nebraska'' but was renamed ''Pennsylvania'' on 7 March 1901. Construction ''Pennsylvania'' was laid down on 7 August 1901, by William Cramp & Sons of Philadelphia, Pennsylvania, and launched on 22 August 1903, sponsored by Miss Coral Quay, daughter of Senator Matthew S. Quay of Pennsylvania. ''Pennsylvania'' was commissioned on 9 March 1905 with Captain Thomas C. McLean in command. Service history Pre-World War I ''Pennsylvania'' operated on the east coast of the United States and in the Caribbean Sea until 8 September 1906, when she cleared Newport for the Asiatic Station, returning to San Francisco on 27 September 1907, for United States West Coast duty. She visited Chile and Peru in 1910. At 10:48 on 18 January 1911, Eugene Ely took ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central America-4 Border Control Agreement
The Central America-4 Free Mobility Agreement (CA-4; ) is a treaty signed in June 2006 between the Central American nations of El Salvador, Guatemala, Honduras, and Nicaragua, establishing the free movement across borders between the four signatory states of their citizens without any restrictions or checks. Foreign nationals who enter one of the signatory countries can also travel to other signatory states by land (but not by air) without having to obtain additional permits or to undergo checks at border checkpoints. Similar to the Schengen Agreement in Europe, the CA-4 Agreement establishes a harmonized visa regime for nationals travelling to the area.
