Cytochrome c is also released from mitochondria due to formation of a channel, the mitochondrial apoptosis-induced channel ( MAC ), in the outer mitochondrial membrane, and serves a regulatory function as it precedes morphological change associated with apoptosis.

MAC, also called " Mitochondrial Outer Membrane Permeabilization Pore " is regulated by various proteins, such as those encoded by the mammalian Bcl-2 family of anti-apoptopic genes, the homologs of the ced-9 gene found in C. elegans.

This is achieved by designating one or more " server " or " provider " nodes, either by MAC address or switch port.

This feature, which is not supported by all DHCP servers, is variously called Static DHCP Assignment by DD-WRT, fixed-address by the dhcpd documentation, Address Reservation by Netgear, DHCP reservation or Static DHCP by Cisco and Linksys, and IP reservation or MAC / IP binding by various other router manufacturers.

This message contains the client's MAC address, the IP address that the server is offering, the subnet mask, the lease duration, and the IP address of the DHCP server making the offer.

As with other IEEE 802 LANs, each Ethernet station is given a 48-bit MAC address.

< span id =" switch_vulnerabilities "> Despite this, switched Ethernet should still be regarded as an insecure network technology, because it is easy to subvert switched Ethernet systems by means such as ARP spoofing and MAC flooding .</ span >

IEEE 802. 15. 3-2003 is a MAC and PHY standard for high-rate ( 11 to 55 Mbit / s ) WPANs.

The IEEE 802. 15 Task Group 4e is chartered to define a MAC amendment to the existing standard 802. 15. 4-2006.

The intent of this amendment is to enhance and add functionality to the 802. 15. 4-2006 MAC to a ) better support the industrial markets and b ) permit compatibility with modifications being proposed within the Chinese WPAN.

IEEE 802. 3 is a working group and a collection of IEEE standards produced by the working group defining the physical layer and data link layer's media access control ( MAC ) of wired Ethernet.

* Hosts have a 48-bit node address which by default is set to the network interface card's MAC address.

As the node address is usually identical to the MAC address of the network adapter, the Address Resolution Protocol is not needed.

Beneath the LLC sublayer is the Media Access Control ( MAC ) sublayer, which is dependent on the particular medium being used ( Ethernet, token ring, FDDI, 802. 11, etc.

IEEE 802. 3 is an exception ; Ethernet originally used Ethernet II framing, with a 2-octet type field containing an EtherType value, and no 802. 2 header, but the original IEEE 802. 3 specification used a framing wherein the 2-octet field following the 6-octet destination and source MAC addresses contained a frame length, with an 802. 2 LLC header following the length field.

Interfaces can have addresses based on the MAC address of the machine ( the EUI-64 format ), but this is not a requirement.

Even when an address is not based on the MAC address though, the interface's address is ( contrary to IPv4 ) usually global instead of local, which makes it much easier to identify a single user through the IP address.

SHA-1 HMAC Generation. In cryptography, a hash-based message authentication code ( HMAC ) is a specific construction for calculating a message authentication code ( MAC ) involving a cryptographic hash function in combination with a secret cryptographic key.

* Mid-Atlantic Center for the Arts & Humanities ( MAC )-a non-profit organization committed to preservation, interpretation and cultural enrichment for Cape May's residents and visitors has been sponsoring vintage dance weekends in Cape May for more than 20 years.

The earliest work directed toward standardizing an approach toward provision of mandatory and discretionary access controls ( MAC and DAC ) within a UNIX ( more precisely, POSIX ) computing environment can be attributed to the National Security Agency's Trusted UNIX ( TRUSIX ) Working Group, which met from 1987 to 1991 and published one Rainbow Book (# 020A ) and produced a formal model and associated evaluation evidence prototype (# 020B ) that was ultimately unpublished.

This means that more lift is generated on the wider inner portions, and the MAC moves the point to measure the chord to take this into account.

The functioning of the Israel Lebanon MAC remained smooth due to the more relaxed attitude of the Israeli patrols towards returnees and infiltrators.

It is used by the majority of enterprises with more than 500 employees, and can implement mandatory access control ( MAC ) or discretionary access control ( DAC ).

In some networks, such as IEEE 802 local area networks, the data link layer is described in more detail with media access control ( MAC ) and logical link control ( LLC ) sublayers ; this means that the IEEE 802. 2 LLC protocol can be used with all of the IEEE 802 MAC layers, such as Ethernet, token ring, IEEE 802. 11, etc., as well as with some non-802 MAC layers such as FDDI.

Currently more operators are running on the 802. 11 MAC at 2 and 5 GHz.

These two products were already market leaders on the MAC, and this success made the Norton merger more strategic.

Fano decided to call MAC a " project " rather than a " laboratory " for reasons of internal MIT politics — if MAC had been called a laboratory, then it would have been more difficult to raid other MIT departments for research staff.

University space-allocation politics being what it is, Minsky found that although Project MAC as a single entity could not get the additional space he wanted, he could split off to form his own lab and then be entitled to more office space.

The same rhetoric of ambition and personal elevation he had employed at MAC resonated more deeply with his Japanese students and, further, with a Japanese nation just emerging from a rigid feudal caste system.

Nb: The y-axis in the accompanying graph is incorrectly labelled and should read " log of Minimum Alveolar Concentration or MAC "-The lesser the MAC the greater the potency ( Halothane has a MAC of slightly less than 1 while Nitrous oxide has a MAC of around 105, halothane is much more potent and it is because the log of the MAC is plotted on the y axis that halothane has a value of 0. 01 and nitrous oxide has a value of 1.

The MAC petition was duly submitted and quickly approved — after all, it was Cole's first success in attracting a group after more than one hundred futile efforts.

Subsequently, E & D's engineers proposed a system of analogue television encoding known as MAC ( Multiplexed Analogue Component ) to provide a standard for the forthcoming satellite television broadcasts that was more robust than an extension of the existing PAL system used for terrestrial broadcasts.

** grsecurity is a complete security solution providing such features as a MAC or RBAC system, chroot restrictions, address space modification protection ( via PaX ), auditing features, randomization features, linking restrictions to prevent file race conditions, ipc protections and much more.

More recently, with the advent of implementations such as SELinux ( incorporated into Linux kernels from 2. 6 ) and Mandatory Integrity Control ( incorporated into Windows Vista and newer ), MAC has started to become more mainstream and is evolving out of the MLS niche.

Another is infection with Mycobacterium avium complex ( MAC ), a group of bacteria related to tuberculosis, which can cause a lot of lung damage and does not respond to common antibiotics.

The diseases associated with AIDS, such as Pneumocystis jiroveci pneumonia ( PCP ) and Mycobacterium avium complex ( MAC ), are not caused by HIV, but rather result from the immunosuppression caused by HIV disease.

* Mycobacterium avium complex ( MAC ), is a group of species that, in a disseminated infection but not lung infection, used to be a significant cause of death in AIDS patients.

C5b initiates the membrane attack pathway, which results in the membrane attack complex ( MAC ), consisting of C5b, C6, C7, C8, and polymeric C9.

* Non-chromogens, which includes a group of prevalent opportunistic pathogens called M. avium complex ( MAC ).

Rifamycins are particularly effective against mycobacteria, and are therefore used to treat tuberculosis, leprosy, and mycobacterium avium complex ( MAC ) infections.

mycobacterium avium complex ( MAC ) –

The membrane attack complex ( MAC ) is typically formed on the surface of pathogenic bacterial cells as a result of the activation of the alternative pathway and the classical pathway of the complement system, and it is one of the effector proteins of the immune system.

The membrane-attack complex ( MAC ) forms transmembrane channels.

The immune complex serves as an activator that triggers a response from the C5b-C9 complements, which form a membrane attack complex ( MAC ) on the glomerular epithelial cells.

* Mycobacterium avium complex ( MAC ) ( Nontuberculosis Mycobacterium )

C5, C6, C7, C8 and C9 form the membrane attack complex ( MAC ).

The worms have many tools that help in this evasion, including the tegument, antioxidant proteins, and defenses against host membrane attack complex ( MAC ).

Microbial pathogens under study include H. influenzae ( Haemophilus influenzae ), MAC Mycobacterium avium complex, gonorrhea, chlamydia, Listeriosis, respiratory bacterial infections, and yeast and mold infections, including candidiasis.
