Why would you use an irrigation staining technique opposed to direct application of iodine?
An irrigation staining technique is used to increase the contrast of soft tissue structures on an imaging study. This is done by injecting a contrast agent into the tissue. The contrast agent is typically iodine-based.
Iodine-based contrast agents can be irritating to the tissue and can cause inflammation. This can lead to increased pain and discomfort for the patient. Additionally, iodine-based contrast agents can cause allergic reactions in some patients.
An irrigation staining technique can help to minimize these side effects by diluting the contrast agent and evenly distributing it throughout the tissue. This can help to improve the comfort of the patient and increase the safety of the procedure.

When bacteria culture age does it appear gram negative or gram positive?
Typically, a negative result can be doubted, but a positive staining cannot be. This is because the vast majority of bacteria that do revert (not to say that the majority of bacteria DO revert) will go from positive to negative. This is due to a decreased average level of peptidoglycan synthesis in Agar culture, as opposed to natural function in vivo. The decreased level of peptidoglycan allows the ethanol/acetone decolorizer to more quickly flush the Crystal Violet from Gram+ cells, making them appear either weakly positive, or fully negative.
Why plastination bad?
If in the context of theoretical brain preservation systems it is bad because it is probably irreversible. As opposed to cryonics which is merely a suspension. Revival of a plastinated (correct word?) brain would basically entail using the the preserved brain as a guide for reconstruction of a high fidelity duplicate. Which opens the door to questions of consciousness and originality. This as opposed to cryonics which involves preservation and reactivation of the original with no duplication step. Such distinctions may be metaphysical in nature but are of paramount importance to some (like me) cryonicists.
Why are some people opposed to stem cell research?
Some people are opposed to stem cell research due to ethical concerns about using human embryos. They believe that human life begins at conception and that destroying embryos for research purposes is morally wrong. Additionally, there are concerns about the potential for misuse of the technology and the need for strict regulations to prevent unethical practices.
What can result in a gram-positive organism staining gram-negative?
The following characteristics are generally present in a Gram-positive bacterium.cytoplasmic lipid membrane teichoic acids and lipoids are present, forming lipoteichoic acids which serve to act as chelating agents, and also for certain types of adherence.thick peptidoglycan layercapsule polysaccharides (only in some species) if present, it contains two rings for support as opposed to four in Gram-negative bacteria because Gram-positive bacteria have only one membrane layer.flagellum (only in some species)Although there is only difference in gram positive and negative is of cell wall as :The Gram positive cell wallThe Gram positive cell wall is characterised by the presence of a very thick peptidoglycan layer, which is responsible for the retention of the crystal violet dyes during the Gram staining procedure. It is found exclusively in organisms belonging to the Actinobacteria (or high %G+C Gram positive organisms) and the Firmicutes (or low %G+C Gram positive organisms). Bacteria within the Deinococcus-Thermus group may also exhibit Gram positive staining behaviour but contain some cell wall structures typical of Gram negative organisms. Imbedded in the Gram positive cell wall are polyalcohols called teichoic acids, some of which are lipid-linked to form lipoteichoic acids. Because lipoteichoic acids are covalently linked to lipids within the cytoplasmic membrane they are responsible for linking the peptidoglycan to the cytoplasmic membrane. Teichoic acids give the Gram positive cell wall an overall negative charge due to the presence of phosphodiester bonds between teichoic acid monomers.The Gram negative cell wallUnlike the Gram positive cell wall, the Gram negative cell wall contains a thin peptidoglycan layer adjacent to the cytoplasmic membrane, which is responsible for the cell wall's inability to retain the crystal violet stain upon decolourisation with ethanol during Gram staining. In addition to the peptidoglycan layer the Gram negative cell wall also contains an additional outer membrane composed by phospholipids and lipopolysaccharides which face into the external environment. The highly charged nature of lipopolysaccharides confer an overall negative charge to the Gram negative cell wall. The chemical structure of the outer membrane lipopolysaccharides is often unique to specific bacterial strains (i.e. sub-species) and is responsible for many of the antigenic properties of these strains.As a phospholipid bilayer, the lipid portion of the outer membrane is largely impermeable to all charged molecules. However, channels called porins are present in the outer membrane that allow for passive transport of many ions, sugars and amino acids across the outer membrane. These molecules are therefore present in the periplasm, the region between the plasma membrane and outer membrane. The periplasm contains the peptidoglycan layer and many proteins responsible for substrate binding or hydrolysis and reception of extracellular signals. The periplasm is thought to exist as a gel-like state rather than a liquid due to the high concentration of proteins and peptidoglycan found within it. Because of its location between the cytoplasmic and outer membranes, signals received and substrates bound are available to be transported across the cytoplasmic membrane using transport and signalling proteins imbedded there.
What are terrestrial ecosystems?
Terrestrial ecosystems refer to the ecosystems found on land, including forests, grasslands, deserts, and tundra. These ecosystems are characterized by the presence of plants and animals adapted to life on land, as opposed to aquatic ecosystems found in water bodies. Terrestrial ecosystems play a crucial role in supporting biodiversity, regulating climate, and providing resources for human beings.
Is a spreadsheet application?
Yes, a spreadsheet is a computer application. It is classed as applications software, as opposed to systems software.
What is standalone application?
It means that it is by itself - as opposed to being bundled with other applications for example.
Processed application couriered to you thus it mean it is approved or denied?
Neither. It simply means that your application is being returned to you by couries as opposed to by mail.
What software consists of programmes that manage and control the use and functioning of the hardware?
System Software as opposed to Application Software, which is what the user interacts with.
What is an application of accrual accounting?
An application of accrual accounting is the notation of expenses as opposed to revenue earned in the same period. Revenue is only shown when it is realized or expected. In accrual accounting assets minus liabilities equals revenue.
What literary technique is this - 'she fitted into the world like a hand into a glove'?
i thinks its a metaphor Edit:It is a simile because the sentence incorperates the word 'like' as opposed to 'is', which makes it a metaphor
What are the most effective surgical and non-surgical techniques for getting rid of stomach fat?
The most effective surgical technique for getting rid of fat (as opposed to weight) is liposuction. The most effective non-surgical technique is watching your diet and getting moderate exercise five times a week.
How did Muslim bookmaking and literature affect the world?
The legacy of early Arabic book binding and the technique's developed by crafting them were a hallmark, if not a cultural zenith, in opposed to the metaphorical nadir of the literature contained within it.
What are specialised applications graphical programs web authoring programs and other professional specialised applications?
A specialised application is simply an application that is written specifically to meet an organisation's needs, as opposed to general purpose applications which are intended to meet the needs of many different organisations.
What is the adverb for apply?
There is a rare derivative adverb, appliably, as opposed to the well-known adverb applicably (related to the noun application). The participle adjectives applying and applied do not form adverbs.
Do you have to pay for the internet on a PSP?
You have to pay for the internet ona psp. Internet is rarely free for any application. However, it may be cheaper on a psp as opposed to a home computer network system.
Why is buckshot called buckshot if you don't hunt bucks with it?
It's the intended application, larger game (primarily deer), as opposed to smaller birdshot (intended for waterfoul and other winged game).
