Alkali denaturation test

The alkali denaturation test, also known as Apt–Downey test or Apt test, is a medical test used to differentiate fetal or neonatal blood from maternal blood found in a newborn's stool or vomitus.

History

The test was developed by Leonard Apt (1922–2013), an American pediatric ophthalmologist. The test was originally used to identify the source of bloody stools in newborn infants. It has been modified to distinguish fetal from maternal hemoglobin in blood samples from any source.

Uses

The Apt test is most commonly used in cases of vaginal bleeding late during pregnancy (antepartum haemorrhage) to determine if the bleeding is from the mother or the fetus.

In practice, the Apt test may not be done when there is suspicion of vasa previa, because the time to fetal collapse with bleeding from vasa previa is often very short.

APT (film)

APT (Hangul: 아파트; RR: Apateu) (released as 9:56 in Singapore) is a 2006 South Korean horror film, directed, produced, and written by Ahn Byeong-ki and starring Ko So-young. It is based on a comic by Kang Full. The name APT is from the English word meaning apartment. The film had 644,893 admissions nationwide.

Plot

Se-jin Oh, a lonely young career woman, lives in a high-rise apartment building in a Seoul suburb, and sometimes watches her neighbors through binoculars for amusement. Taking the subway home one night near Christmas, a woman dressed in red throws herself in front of the train, attempting to drag Se-jin with her. The dead woman haunts Se-jin, though she doesn't know it. However, she does notice that the lights across the way flicker mysteriously at exactly 9:56pm every night—often accompanied by an apparent suicide.

Se-jin is befriended by Yoo-yeon, a wheelchair-bound woman abused by her caregivers, several of whom are among the victims. Yoo-yeon gives Se-jin a puzzle cube, noting it can help to forget the pain for a while. Se-jin attempts to influence her neighbors, begging them to not turn their lights off before 10 pm. This puts her in conflict with police detective Yang, who learns that many of the victims have identical keys to an apartment. The apartment that matches the key, 704, is Yoo-yeon's -- but Yang finds the resident is Shin Jung-soo, a social recluse with long black hair, who attacks Yang, but denies having committed any murders.

6-APT

6-(2-Aminopropyl)tetralin (6-APT), also sometimes called tetralinylaminopropane (TAP), is a drug of the amphetamine class which acts as a selective serotonin releasing agent (SSRA). It has IC₅₀ values of 121 nM, 6,436 nM, and 3,371 nM for inhibiting the reuptake of serotonin, dopamine, and norepinephrine, respectively. Though it possesses an appreciable in vitro profile, in animal drug discrimination studies it was not found to substitute for MMAI or amphetamine and to only partially substitute for MBDB. This parallels Alexander Shulgin's finding that EDMA (the 1,4-benzodioxine analogue of 6-APT) is inactive, and appears to indicate that the pharmacokinetics of both EDMA and 6-APT may not be favorable.

Advanced Packaging Tool

The Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on the Debian Linux distribution and its variants. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.

APT was originally designed as a front-end for dpkg to work with Debian's .deb packages, but it has since been modified to also work with the RPM Package Manager system via APT-RPM. The Fink project has ported APT to Mac OS X for some of its own package management tasks, and APT is also available in OpenSolaris.

Usage

There has been an apt program since version 1.0; apt is a collection of tools distributed in a package named apt. A significant part of apt is defined in a C++ library of functions; apt also includes command-line programs for dealing with packages, which use the library. Three such programs are apt, apt-get and apt-cache. They are commonly used in examples of apt because they are simple and ubiquitous. The apt package is of "important" priority in all current Debian releases, and is therefore installed in a default Debian installation. Apt can be considered a front-end to dpkg, friendlier than the older dselect front-end. While dpkg performs actions on individual packages, apt tools manage relations (especially dependencies) between them, as well as sourcing and management of higher-level versioning decisions (release tracking and version pinning).
