The word brane, derived from " membrane ", refers to a variety of interrelated objects, such as D-branes, black p-branes and Neveu – Schwarz 5-branes.

The hymen is, in essence, a fragile membrane that more or less completely covers the entrance to the vagina in most female human beings who have not had sex relations.

( Hymen, in fact, is the Greek word for membrane.

Orthodontic work is possible because teeth are held firmly but not rigidly, by a system of peridontal membrane with an involved nerve network, to the bone in the jaw ; ;

Amoebas breathe using their entire cell membrane that is constantly immersed in water.

Undigested food is expelled at the cell membrane.

This is an antimicrobial peptides that attaches to the cell membrane of the bacteria and destroys it.

** Immunomodulation, e. g., tetracycline, which is effective in periodontal inflammation, and dapsone, which is effective in autoimmune diseases such as oral mucous membrane pemphigoid

* The cell is surrounded by a pellicle of three membrane layers ( the alveolar structure ) penetrated by micropores.

Over the rest of the cell, except for a diminished mouth called the micropore, the membrane is supported by vesicles called alveoli, forming a semi-rigid pellicle.

Surface immunoglobulin ( Ig ) is attached to the membrane of the effector B cells by its transmembrane region, while antibodies are the secreted form of Ig and lack the trans membrane region so that antibodies can be secreted into the bloodstream and body cavities.

There is also a growing body of evidence indicating that nitric oxide is able to induce apoptosis by helping to dissipate the membrane potential of mitochondria and therefore make it more permeable.

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.

Phosphatidylserine is normally found on the cytosolic surface of the plasma membrane, but is redistributed during apoptosis to the extracellular surface by a hypothetical protein known as scramblase.

When HeLA cells are infected with OROV, the cytochrome C is released from the membrane of the mitochondria, into the cytosol of the cells.

Inside the mitochondria, AIF is anchored to the inner membrane.

The effect of adrenaline is via a G protein signaling cascade, which transmits chemical signals from outside the cell across the membrane to the inside of the cell ( cytoplasm ).

The protein is organized with 6 transmembrane segments, then the C1 cytoplasmic domain, then another 6 membrane segments, and then a second cytoplasmic domain called C2.

Much research is carried out into thin amorphous films as a gas separating membrane layer.

It is believed that the mechanisms are multifaceted and include the following: 1 ) Potassium or glutamate leakage through the outer membrane of bacteria ; 2 ) Osmotic balance disturbances ; 3 ) Binding to proteins that do not require or utilize copper ; 4 ) Oxidative stress by hydrogen peroxide generation.

) folded or arched metal ring attached to a thick wood rim, over which a skin, or most often, a plastic membrane ( or head ) is stretched-it is the bell bronze that gives the banjo a crisp powerful lower register and clear, bell-like treble register-especially in bluegrass music.

A drum is called a membranophone, or an instrument that creates sound by striking a stretched membrane with some type of object, usually a rounded stick.

In 1997, Juan Maldacena gave the first holographic descriptions of a higher dimensional object, the 3 + 1 dimensional type IIB membrane, which resolved a long-standing problem of finding a string description which describes a gauge theory.

The membrane is then rubbed with a round flat object (“ pouncing ”) to ensure that the ink would adhere well.

The walls of the vagina are composed of soft elastic folds of mucous membrane which stretch or contract ( with support from pelvic muscles ) to the size of the inserted penis or other object, stimulating the penis and helping to cause the male to experience orgasm and ejaculation, thus enabling fertilization.

Others are made when an object outside of the cell is surrounded by the cell membrane.

The proteins of the membrane skeleton are responsible for the deformability, flexibility and durability of the red blood cell, enabling it to squeeze through capillaries less than half the diameter of the erythrocyte ( 7-8 μm ) and recovering the discoid shape as soon as these cells stop receiving compressive forces, in a similar fashion to an object made of rubber.

This technique enables the levitation of an object against gravitational force by floating on a thin gas film formed by gas flow through a porous membrane.

This is achieved by placing the mridangam upright with its larger side facing down, and then striking the tension-bearing straps located along of circumference of the right membrane with a heavy object ( such as a stone ).

The forensic physician, a Captain in the Russian military medical service, found three tears in her hymen and one in the mucous membrane of her rectum, and the report concludes that she was penetrated anally and vaginally by a blunt object after death.

The in modifier causes the object to be passed to one of the current membrane ’ s children ( travelling inwards relative to the structure of the P system ), chosen at random during the computation.

The out modifier causes the object to be passed out of the current membrane and into either its parent membrane or to a sibling membrane, specified during specification of the P system.

From the initial configuration only membrane 3 has any object content: " ac "

Membrane 3 now dissolves, as the dissolve symbol ( δ ) has been encountered and all object content from this membrane passes into membrane 2.

Consider the case where " a " is assigned to a → bδ during step 1: upon membrane 3 dissolving only a single " b " and two " c " objects would exist, leading to the creation of only a single " e " object to eventually be passed out as the computation ’ s result.

* Macropinocytosis, which usually occurs from highly ruffled regions of the plasma membrane, is the invagination of the cell membrane to form a pocket, which then pinches off into the cell to form a vesicle ( 0. 5 – 5 µm in diameter ) filled with a large volume of extracellular fluid and molecules within it ( equivalent to ~ 100 CCVs ).

* Filter ( chemistry ), a device ( usually a membrane or layer ) that is designed to physically block certain objects or substances while letting others through

Construction of a high temperature proton exchange membrane fuel cell | PEMFC: Bipolar plate as electrode with in-milled gas channel structure, fabricated from conductive composite material | composite s ( enhanced with graphite, carbon black, carbon fiber, and / or carbon nanotube s for more conductivity ); Porous carbon papers ; reactive layer, usually on the polymer membrane applied ; polymer membrane. Condensation of water produced by a PEMFC on the air channel wall.

The membrane electrode assembly ( MEA ), is referred as the heart of the PEMFC and usually made of a proton exchange membrane sandwiched between two catalyst coated carbon papers.

Such " multi-subunit " assemblies usually involve a circular arrangement of identical or homologous proteins closely packed around a water-filled pore through the plane of the membrane or lipid bilayer.

This process usually begins with cell lysis, in which a cell's membrane is disrupted and its internal contents released into a solution known as a crude lysate.

Bound ribosomes usually produce proteins that are used within the plasma membrane or are expelled from the cell via exocytosis.

Buffer transfer by capillary action from a region of high water potential to a region of low water potential ( usually filter paper and paper tissues ) is then used to move the DNA from the gel on to the membrane ; ion exchange interactions bind the DNA to the membrane due to the negative charge of the DNA and positive charge of the membrane.

Subsequently, a soft part of the prey item ( usually a joint membrane in arthropod prey ) is identified, punctured with a bite from the jaws, and injected with saliva.

Unlike the hydrozoan jellyfish, hydromedusae, scyphomedusae lack a velum, which is a circular membrane beneath the umbrella that helps propels the ( usually smaller ) hydromedusae through the water.

Oxidative damage to erythrocyte cell membrane is usually inhibited by glutathione ; however, with reduced ATP levels caused by ribavirin, glutathione levels are impaired, permitting oxidative erythrocyte cell lysis.

The F < sub > o </ sub > F < sub > 1 </ sub > ATP synthase of mitochondria, in contrast, usually conduct protons from high to low concentration across the membrane while drawing energy from this flow to synthesize ATP.

The other cases, which usually derive their energy through exploitation of an electrochemical gradient, are known as secondary active transport and involve pore-forming proteins that form channels through the cell membrane.

It is important to note that mechanical perturbations, which usually destroy a biological lipid membrane, do not influence the life-time of an SSM.

In neurons, the types of ion channels in the membrane usually vary across different parts of the cell, giving the dendrites, axon, and cell body different electrical properties.

The portion of the protein that is not touching the lipid bilayer and is protruding out of the cell membrane are usually hydrophilic amino acids.

A small hole in each gourd is covered with a membrane traditionally of thin spider's-egg sac filaments ( nowadays more usually of cigarette paper or thin plastic film ) to produce the characteristic nasal-buzz timbre of the instrument, which is usually played with two gum-rubber-wound mallets while seated on a low stool ( or while standing using a shoulder or waist sling hooked to its frame ).
