In most studies, the OAV and 5D-ASC were completed during or shortly after the drug effects peaked. However, in some studies, these rating scales were completed after the drug effects had worn off or at multiple time points. In the latter case, we only included those measures that were obtained during the peak drug effect. Depending on the study, the pooled OAV and 5D-ASC questionnaires were completed 60–300 min after psilocybin, 25–120 min after ketamine, and 70–160 min after MDMA administration. Subjects were instructed to retrospectively rate their whole experience from the moment of drug intake to the respective measuring time point.
Ketamine
It works by blocking the activity of the N-methyl-D-aspartate (NMDA) receptor, which is involved in the transmission of pain signals and the regulation of mood.
Ketamine has a rapid onset of action and can produce dissociative effects, which means that the user may feel detached from their body or surroundings.
In recent years, ketamine has also been explored as a potential treatment for conditions such as chronic pain, suicidal ideation, and post-traumatic stress disorder.
However, ketamine can also have side effects, such as hallucinations, disorientation, and respiratory depression, and its use should be carefully monitored by healthcare professionals.
Reseachers can use PubCompare.ai's AI-driven platform to optimize their ketamine reseach, easily locate protocols from literature, preprints, and patents, and use AI-powered comparisons to identify the best protocols and products for their needs, enhancing reproducibility and accuracy in their ketamine studies.

For the retinal ganglion cell-superior colliculus experiment, intravitreal virus injection was performed on P0 C57BL/6 mice with Nanoject II (Drummond) under cold anesthesia. 100 nL of rAAV2/8-Synapsin-Chronos-GFP (titer 1.4×1013 particles/mL) was injected into the eye. AAV particles were produced by the University of North Carolina Chapel Hill Vector Core.

In the following experiments, a mouse model of RVO, which induces reproducible retinal edema was used. RVO is the model that was used for testing anti-VEGF therapies for DME. Brown et al., Ophthalmology 117, 1124-1133 el 121 (2010); and Campochiaro et al., Ophthalmology 117, 1102-1112 e1101 (2010). I n this model, Rose Bengal, a photoactivatable dye, is injected into the tail veins of adult C57B16 mice and photoactivated by laser of retinal veins around the optic nerve head. A clot is formed and edema or increased retinal thickness develops rapidly. Inflammation, also seen in diabetes, also develops.
Fluorescein leakage and maximal retinal edema, measured by fluorescein angiography and optical coherence tomography (OCT), respectively, using the Phoenix Micron IV, is observed 24 h after RVO. Retinal edema is maintained over the first 3 days RVO. By day 4 the edema decreases and the retina subsequently thins out. In addition to edema formation there is evidence of cell death in the photoreceptor cell layer by day 2 after RVO.
In this example, mice were anesthetized with intra-peritoneal (IP) injection of ketamine and xylazine. One drop of 0.5% alcaine was added to the eye as topical anesthetic. The retina was imaged with the Phoenix Micron IV to choose veins for laser ablation using the Phoenix Micron IV image guided laser. One to four veins around the optic nerve head were ablated by delivering a laser pulse (power 50 mW, spot size 50 μm, duration 3 seconds) to each vein.

The discovery of rapidly acting antidepressants, such as ketamine, has transformed our ideas about depression treatment. Based on the above-described data (
Mice received i.p. injections of 1, 5, or 10 mg/kg CN2097 or 1 or 5 mg/kg dR7-2097.
As shown in the

A lidocaine preservative free intranasal formulation with combination of other drugs is prepared using the ingredients set forth in Table 4 for Examples 6-8.
The formulation is prepared as follows: Add citric acid monohydrate to purified water while stirring and mix till a clear solution is observed. Add lidocaine base or salt, combination drug and other optional excipients while stirring and mix for 30 minutes till a clear solution is formed. Filter the clear solution using sterile 0.2 micron pore size filter and fill the solution in a glass bottle aseptically and tightly crimp metered dose mechanical pump.

To further test CN2097, we used the Chronic Mild Stress (CMS) model which has been shown to evoke anxiety and lower sucrose consumption (postulated to reflect anhedonia), symptoms associated with MDD. As described in Marshall (2018),44 mice subjected to repeated daily stress for 3 weeks, then received a single injection of CN2097 (10 mg/kg) or vehicle.
The acute effects of CN2097 on anxiety were evaluated by the elevated plus-maze (EPM) and novelty-suppressed feeding (NSF) tests. As shown in
In the NSF test, anxiety-induced hypophagia was assessed by measuring the latency of mice to eat a familiar food in an aversive environment. As shown in
The CMS model responds to chronic, but not acute, administration of established antidepressant drugs.45 Based on the predictive value of the CMS model,46 the above-described data showing that CN2097 caused a reversal of anhedonic and other behavioral effects within 2 hours (

Oncomice®, obtained through an in-house breeding program, were anesthetized intramuscularly with 0.1 mL of ketamine/acepromazine (1.8 mL saline, 1.0 mL ketamine, and 0.2 mL acepromazine) prior to dosing and tissue sampling. Individual mice were then injected via the tail vein with an imaging agent of the present invention (0.5-2.0 mCi/kg in 0.1 mL). Mice were euthanized and biodistribution performed at 1 h post-injection. Selected tissues were removed, weighed, and counted on a gamma counter. Results are expressed as the percentage of injected dose per gram tissue (mean±SEM; Table 3).

More about "Ketamine"
This versatile compound, also known by the brand names Ketalar and Rompun, has demonstrated remarkable potential in the management of various medical conditions, including pain, depression, and post-traumatic stress disorder.
Ketamine works by blocking the activity of the N-methyl-D-aspartate (NMDA) receptor, a key player in the transmission of pain signals and the regulation of mood.
Its rapid onset of action and ability to induce a dissociative state, where the user may feel detached from their body or surroundings, have made it a valuable tool in both medical and recreational settings.
In the realm of pain management, ketamine has been explored as a treatment for chronic pain conditions, often in combination with other analgesics.
Researchers have also investigated the use of ketamine in the treatment of depression, particularly in individuals with treatment-resistant forms of the condition.
Additionally, the drug has shown promise in addressing suicidal ideation and post-traumatic stress disorder.
When it comes to research methodologies, ketamine studies often involve the use of animal models, such as C57BL/6 and C57BL/6J mice.
These mouse strains are commonly used in neuroscience and pharmacology research, and researchers may employ techniques like stereotaxic frames to precisely administer the drug and study its effects.
While the potential benefits of ketamine are substantial, it is important to note that the drug can also have side effects, such as hallucinations, disorientation, and respiratory depression.
As such, the use of ketamine should be carefully monitored by healthcare professionals to ensure the safety and well-being of patients.
In conclusion, the versatility of ketamine, combined with its unique mechanism of action, has made it a subject of intense interest in the medical and research communities.
By leveraging the power of AI-driven platforms like PubComapre.ai, researchers can optimize their ketamine studies, streamline the process of locating relevant protocols, and enhance the reproducibility and accuracy of their findings.
