Parathyroid Hormone
Parathyroid hormone (PTH), also called parathormone or parathyrin, is a peptide hormone secreted by the parathyroid glands that regulates the serum calcium concentration through its effects on bone, kidney, and intestine. PTH influences bone remodeling, which is an ongoing process in which bone tissue is alternately resorbed and rebuilt over time. PTH is secreted in response to low blood serum calcium (Ca2+) levels. PTH indirectly stimulates osteoclast activity within the bone matrix (osteon), in an effort to release more ionic calcium (Ca2+) into the blood to elevate a low serum calcium level. The bones act as a (metaphorical) "bank of calcium" from which the body can make "withdrawals" as needed to keep the amount of calcium in the blood at appropriate levels despite the ever-present challenges of metabolism, stress, and nutritional variations. PTH is "a key that unlocks the bank vault" to remove the calcium. PTH is secreted primarily by the chief cells of the parathyroi ...

Edman Degradation
Edman degradation, developed by Pehr Edman, is a method of sequencing amino acids in a peptide. In this method, the amino-terminal residue is labeled and cleaved from the peptide without disrupting the peptide bonds between other amino acid residues. Mechanism Phenyl isothiocyanate is reacted with an uncharged N-terminal amino group, under mildly alkaline conditions, to form a cyclical ''phenylthiocarbamoyl'' derivative. Then, under acidic conditions, this derivative of the terminal amino acid is cleaved as a thiazolinone derivative. The thiazolinone amino acid is then selectively extracted into an organic solvent and treated with acid to form the more stable phenylthiohydantoin (PTH)- amino acid derivative that can be identified by using chromatography or electrophoresis. This procedure can then be repeated again to identify the next amino acid. A major drawback to this technique is that the peptides being sequenced in this manner cannot have more than 50 to 60 residues (and ...

GNU Portable Threads
GNU Pth (Portable Threads) is a POSIX/ANSI- C based user space thread library for UNIX platforms that provides priority-based scheduling for multithreading applications. GNU Pth targets for a high degree of portability. It is part of the GNU Project. Pth also provides API emulation for POSIX threads for backward compatibility. GNU Pth uses an N:1 mapping to kernel-space threads, i.e., the scheduling is done completely by the GNU Pth library and the kernel itself is not aware of the N threads in user-space. Because of this there is no possibility to utilize SMP as kernel dispatching would be necessary.

Pass The Hash
In computer security, pass the hash is a hacking technique that allows an attacker to authenticate to a remote server or service by using the underlying NTLM or LanMan hash of a user's password, instead of requiring the associated plaintext password as is normally the case. It replaces the need for stealing the plaintext password to gain access with stealing the hash. The attack exploits an implementation weakness in the authentication protocol, where password hashes remain static from session to session until the password is next changed. This technique can be performed against any server or service accepting LM or NTLM authentication, whether it runs on a machine with Windows, Unix, or any other operating system. Description On systems or services using NTLM authentication, users' passwords are never sent in cleartext over the wire. Instead, they are provided to the requesting system, like a domain controller, as a hash in a response to a challenge–response authentication ...

The 2,950 individuals in the Pataxó tribe now speak Portuguese instead, though they retain a few Pataxó words, as well as some words from neighbouring peoples. History of documentation In 1961, a Pataxó speaker named Tšitši'a was recorded by Wilbur Pickering in Posto Caramurú (located 3 kilometers from Itaju, Bahia). Tšitši'a was married to a Baenã woman, but she could not speak the Baenã language. Pataxó people were also reported to be living in Itagüira, Itabuna, Bahia.

Standard Chinese
Standard Chinese ()—in linguistics Standard Northern Mandarin or Standard Beijing Mandarin, in common speech simply Mandarin, better qualified as Standard Mandarin, Modern Standard Mandarin or Standard Mandarin Chinese—is a modern Standard language, standardized form of Mandarin Chinese that was first developed during the Republic of China (1912–1949), Republican Era (1912‒1949). It is designated as the official language of Languages of China, mainland China and a major language in the United Nations languages, United Nations, Languages of Singapore, Singapore, and Languages of Taiwan, Taiwan. It is largely based on the Beijing dialect. Standard Chinese is a pluricentric language with local standards in mainland China, Taiwan and Singapore that mainly differ in their lexicon. Hong Kong written Chinese, used for formal written communication in Hong Kong and Macau, is a form of Standard Chinese that is read aloud with the Cantonese reading of characters.

Port Huron (Amtrak Station)
Port Huron station is an Amtrak station in Port Huron, Michigan, and the eastern terminus of the . The current station opened in 1979. It sits six blocks west of the St. Clair Tunnel, but the passenger tracks now terminate here and only freight tracks bypass the station and continue to Canada. Port Huron is the division point between the Flint Subdivision to Battle Creek, Michigan, and the Strathroy Subdivision to London, Ontario. The station was formerly served by the '' International Limited'', which was operated jointly by Via Rail and Amtrak between Chicago and Toronto. The service, which had started in 1982, was discontinued in 2004. The Port Huron station had contained a United States Immigration Office while it served the ''International Limited''.

Primary Routes These Provincial Trunk Highways are numbered from 1 to 99 for mainline routes and 100 to 199 for loop/spur routes (only four currently exist). Provincial Trunk Highways 1 and 75, as well as the Perimeter Highway (PTH 100/PTH 101), are the most important and are divided highways for most of their length with some sections at expressway or freeway standards. PTHs 1A (Brandon), 3, 4, 7, 8, 9, 9A, 10, 12, 14, 16, 44, 52 and 59 also have some divided sections. Speed limits are generally 90 km/h (55 mph) to 110 km/h (70 mph). Secondary Routes These Provincial Roads are numbered from 200 to 632. Some of these routes are gravel for part or all of their le ...

Plated Through-hole
In electronics, through-hole technology (also spelled "thru-hole") is a manufacturing scheme in which leads on the components are inserted through holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side, either by manual assembly (hand placement) or by the use of automated insertion mount machines. History Through-hole technology almost completely replaced earlier electronics assembly techniques such as point-to-point construction. From the second generation of computers in the 1950s until surface-mount technology (SMT) became popular in the mid 1980s, every component on a typical PCB was a through-hole component. PCBs initially had tracks printed on one side only, later both sides, then multi-layer boards were in use. Through holes became plated-through holes (PTH) in order for the components to make contact with the required conductive layers. Plated-through holes are no longer required with SMT boards for making the component connection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
