The Gram stain is an example of a differential staining procedure, which takes advantage of the fact that cells or parts of cells react differently and can be distinguished by the use of two different dyes. In the Gram staining technique, a crystal violet dye is applied to the bacterial cells, followed by iodine solution. This forms a complex that is retained by Gram-positive bacteria, giving them a purple color. In contrast, Gram-negative bacteria are decolorized by alcohol or acetone, and a counterstain, typically safranin, is applied to give them a pink/red color.

The Gram stain is widely used in microbiology to differentiate bacteria into two major groups, Gram-positive and Gram-negative, based on the differences in their cell wall structure. Gram-positive bacteria have a thick peptidoglycan layer that retains the crystal violet dye, while Gram-negative bacteria have a thinner peptidoglycan layer and an outer membrane that allows the dye to be washed away.

Overall, the Gram stain is a valuable tool for the initial identification and classification of bacteria in clinical, research, and diagnostic settings.

It is possible to cause the presynaptic terminal of an axon to release its transmitter without an action potential. This can be done by direct application of a neurotransmitter agonist or a receptor agonist.

A neurotransmitter agonist mimics the action of the neurotransmitter, activating postsynaptic receptors on the postsynaptic terminal, which triggers the release of neurotransmitters in the presynaptic terminal. A receptor agonist binds to the specific receptors found on the presynaptic neuron, causing the release of neurotransmitter without an action potential.

This type of release is known as “non-canonical neurotransmission”. In addition, application of certain types of electrical stimuli, such as current directly applied to the presynaptic neuron, can also induce neurotransmitter release without an action potential. This is known as “non-electrogenic neurotransmission”.

Non-canonical and non-electrogenic neurotransmission are two mechanisms that can be used to cause a presynaptic neuron to release its transmitter without the need for an action potential.

During the ictal state, as a seizure initiates, the spatio-temporal dynamics of the brain reach a homogeneous state, which can lead to increased functional connectivity (fc).

The ictal state refers to the active phase of a seizure when abnormal electrical activity spreads throughout the brain. During this state, there is a disruption in the normal functioning of neuronal networks, leading to the manifestation of seizure symptoms. The spatio-temporal dynamics of the brain, which refers to the patterns of activity and their temporal evolution, undergo significant changes during the ictal state.

As a seizure begins, the abnormal electrical activity can rapidly propagate across different regions of the brain, causing a synchronization of neuronal firing. This synchronization leads to the formation of a homogeneous state where the activity of neurons becomes more coordinated. This increased synchrony and coherence in neuronal activity contribute to the generation and propagation of the seizure.

Functional connectivity (fc) refers to the statistical dependence or correlation between the activity of different brain regions. In the ictal state, the spatio-temporal dynamics of the brain reaching a homogeneous state can result in increased functional connectivity. The synchronization of neuronal firing and the propagation of abnormal electrical activity during a seizure can strengthen the connections between brain regions, leading to enhanced functional connectivity.

Increased functional connectivity during the ictal state can have both positive and negative consequences. On one hand, it may facilitate the spread of the seizure activity, leading to more severe and prolonged seizures. On the other hand, it may also contribute to the generation of aberrant brain activity that underlies the seizure. Understanding the mechanisms of increased functional connectivity during seizures is crucial for developing effective treatments and interventions for epilepsy.

The 3' hydroxyl from the RNA being extended acts as the nucleophile in the mechanism of nucleotide addition by RNA polymerase.

During RNA synthesis, RNA polymerase catalyzes the addition of nucleotides to the growing RNA chain. The nucleotide addition occurs through a process called nucleophilic attack, where a nucleophile attacks an electrophilic substrate. In the case of RNA polymerase, the 3' hydroxyl (-OH) group of the RNA being extended acts as the nucleophile.

As RNA polymerase moves along the DNA template, it adds nucleotides to the growing RNA chain. The incoming nucleotide is present as a triphosphate molecule, with the α-phosphate attached to the 5' carbon of the ribose sugar. When the correct nucleotide is positioned at the active site of RNA polymerase, the two terminal phosphates are cleaved, releasing pyrophosphate (PPi). This cleavage generates a high-energy phosphoanhydride bond.

The 3' hydroxyl of the RNA being extended then attacks the α-phosphate of the incoming nucleotide, resulting in the formation of a phosphodiester bond between the growing RNA chain and the new nucleotide. This nucleophilic attack leads to the release of pyrophosphate and the elongation of the RNA chain.
