3-Arylpropiolonitriles
3-Arylpropiolonitriles (APN) belong to a class of electron-deficient alkyne derivatives substituted by two electron-withdrawing groups – a nitrile and an aryl moieties. Such activation results in improved selectivity towards highly reactive thiol-containing molecules, namely cysteine residues in proteins. APN-based modification of proteins was reported to surpass several important drawbacks of existing strategies in bioconjugation, notably the presence of side reactions with other nucleophilic amino acid residues and the relative instability of the resulting bioconjugates in the blood stream. The latter drawback is especially important for the preparation of targeted therapies, such as antibody-drug conjugates. Synthesis The synthesis of 3-arylpropiolonitriles has been the subject of several studies. The most elaborated and often used approach is based on MnO2-mediated free radical oxidation of the corresponding propargylic alcohols obtained using Sonogashira coupling of the cor ...

Acute Pyelonephritis
Pyelonephritis is inflammation of the kidney, typically due to a bacterial infection. Symptoms most often include fever and flank tenderness. Other symptoms may include nausea, burning with urination, and frequent urination. Complications may include pus around the kidney, sepsis, or kidney failure. It is typically due to a bacterial infection, most commonly ''Escherichia coli''. Risk factors include sexual intercourse, prior urinary tract infections, diabetes, structural problems of the urinary tract, and spermicide use. The mechanism of infection is usually spread up the urinary tract. Less often infection occurs through the bloodstream. Diagnosis is typically based on symptoms and supported by urinalysis. If there is no improvement with treatment, medical imaging may be recommended. Pyelonephritis may be preventable by urination after sex and drinking sufficient fluids. Once present it is generally treated with antibiotics, such as ciprofloxacin or ceftriaxone. Those with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acyl Peroxy Nitrates
In organic chemistry, peroxyacyl nitrates (also known as Acyl peroxy nitrates, APN or PANs) are powerful respiratory and eye irritants present in photochemical smog. They are nitrates produced in the thermal equilibrium between organic peroxy radicals by the gas-phase oxidation of a variety of volatile organic compounds (VOCs), or by aldehydes and other oxygenated VOCs oxidizing in the presence of . For example, peroxyacetyl nitrate, : :Hydrocarbons + O2 + NO2 + light -> CH3COOONO2 The general equation is: :C_\mathitH_\mathitO3 + NO2 -> C_\mathitH_\mathitO3NO2 They are good markers for the source of VOCs as either biogenic or anthropogenic, which is useful in the study of global and local effects of pollutants. PANs are both toxic and irritating, as they dissolve more readily in water than ozone. They are lachrymators, causing eye irritation at concentrations of only a few parts per billion. At higher concentrations they cause extensive damage to vegetation. Both PANs and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Access Point Name
An Access Point Name (APN) is the name of a gateway between a GSM, GPRS, 3G and 4G mobile network and another computer network, frequently the public Internet. A mobile device making a data connection must be configured with an APN to present to the carrier. The carrier will then examine this identifier to determine what type of network connection should be created, for example: which IP addresses should be assigned to the wireless device, which security methods should be used, and how, or if, it should be connected to some private customer network. More specifically, the APN identifies the packet data network (PDN) that a mobile data user wants to communicate with. In addition to identifying a PDN, an APN may also be used to define the type of service, (e.g. connection to Wireless Application Protocol (WAP) server, Multimedia Messaging Service (MMS)) that is provided by the PDN. APN is used in 3GPP data access networks, e.g. General Packet Radio Service (GPRS), evolved packet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application-Layer Protocol Negotiation
Application-Layer Protocol Negotiation (ALPN) is a Transport Layer Security (TLS) extension that allows the application layer to negotiate which protocol should be performed over a secure connection in a manner that avoids additional round trips and which is independent of the application-layer protocols. It is used to establish HTTP/2 connections without additional round trips (client and server can communicate over to ports previously assigned to HTTPS with HTTP/1.1 and upgrade to use HTTP/2 or continue with HTTP/1.1 without closing the initial connection). Support ALPN is supported by these libraries: * BSAFE Micro Edition Suite since version 5.0 * GnuTLS since version 3.2.0 released in May 2013 * MatrixSSL since version 3.7.1 released in December 2014 * Network Security Services since version 3.15.5 released in April 2014 * OpenSSL since version 1.0.2 released in January 2015 * LibreSSL since version 2.1.3 released in January 2015 * mbed TLS (previously PolarSSL) since versio ...

Algebraic Petri Net
An algebraic Petri net (APN) is an evolution of the well known Petri net in which elements of user defined data types (called algebraic abstract data types (AADT)) replace black tokens. This formalism can be compared to coloured Petri nets (CPN) in many aspects. However, in the APN case, the semantics of the data types is given by an axiomatization enabling proofs and computations on it. Algebraic Petri nets were invented by Jacques Vautherin in 1985 in his PhD thesis and later improved by Wolfang Reisig. The formalism has two aspects : * The control part which is handled by a Petri net. * The data part which is handled by one or many AADTs. AADT can be themselves split in two parts: * The ''signature'' (Sort and Ops in the example below) which gives the valid constants and operations of the term algebra. * The ''axiomatization'' (Axioms in the example below) which gives the semantics of the operations described in the signature part. The following picture describes an algebraic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
