Meclofenoxate
Meclofenoxate (International Nonproprietary Name, INN, British Approved Name, BAN; brand name Lucidril, also known as centrophenoxine) is a cholinergic nootropic used as a dietary supplement. It is an ester of dimethylethanolamine (DMAE) and 4-Chlorophenoxyacetic acid, 4-chlorophenoxyacetic acid (pCPA). In elderly patients, meclofenoxate has been shown to improve performance on certain memory tests. Meclofenoxate also increases cellular membrane phospholipids. It is sold in Japan and some European countries, such as Germany, Hungary, and Austria, as a prescription drug. Side effects Meclofenoxate is considered to be very safe and high in tolerability. However, possible side effects may include, rarely, insomnia, dizziness, Psychomotor agitation, restlessness, muscle tremor, depression (mood), depression, nausea, muscle tension, and headache; these side effects may be due to overdose, overdosage and may indicate the need for the dosage to be reduced.

ISRIB
ISRIB (integrated stress response inhibitor) is an experimental drug that reverses the effects of eIF2α phosphorylation with an IC50 of 5 nM. It was discovered in the laboratory of Peter Walter at University of California, San Francisco (UCSF) through a semi-automated screening of a large library of small molecules by Carmela Sidrauski, who decided to pursue research on it.Piore, Adam, The miracle molecule that could treat brain injuries and boost your fading memory', MIT Technology Review, August 25, 2021 (Carmela Sidrauski interview) It has been shown to inhibit eIF2α phosphorylation-induced stress granule (SG) formation. Since eIF2α phosphorylation is known to be involved in memory formation, ISRIB was tested to see whether it would be active ''in vivo'', and was found to readily cross the blood–brain barrier, with a half-life of eight hours. Subsequent testing in 2013 found ISRIB to produce significant nootropic effects in mice, as measured by enhancement of spat ...

Dizziness
Dizziness is an imprecise term that can refer to a sense of disorientation in space, vertigo, or lightheadedness. It can also refer to disequilibrium or a non-specific feeling, such as giddiness or foolishness. Dizziness is a common medical complaint, affecting 20-30% of persons. Dizziness is broken down into 4 main subtypes: vertigo (~25-50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). * Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find vertigo very disturbing and often report associated nausea and vomiting. * Presyncope describes lightheadedness or feeling faint; the name relates to syncope, which is actually fainting. * Disequilibrium is the sensation of being off balance and is most often characterized by frequent falls in a specific direction. This condition is not often associated with nausea or vomiting. * Non-specific dizziness may be psychiatric in origin. It is ...

Antidementia Agents
Dementia is a disorder which manifests as a set of related symptoms, which usually surfaces when the brain is damaged by injury or disease. The symptoms involve progressive impairments in memory, thinking, and behavior, which negatively affects a person's ability to function and carry out everyday activities. Aside from memory impairment and a disruption in thought patterns, the most common symptoms include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Consciousness is not affected. Dementia ultimately has a significant effect on the individual, caregivers, and on social relationships in general. A diagnosis of dementia requires the observation of a change from a person's usual mental functioning, and a greater cognitive decline than what is caused by normal aging. Several diseases and injuries to the brain, such as a stroke, can give rise to dementia. However, the mo ...

Dimethylamino Compounds
Dimethylamine is an organic compound with the formula (CH3)2NH. This secondary amine is a colorless, flammable gas with an ammonia-like odor. Dimethylamine is commonly encountered commercially as a solution in water at concentrations up to around 40%. An estimated 270,000 tons were produced in 2005. Structure and synthesis The molecule consists of a nitrogen atom with two methyl substituents and one proton. Dimethylamine is a weak base and the pKa of the ammonium CH3--CH3 is 10.73, a value above methylamine (10.64) and trimethylamine (9.79). Dimethylamine reacts with acids to form salts, such as dimethylamine hydrochloride, an odorless white solid with a melting point of 171.5 °C. Dimethylamine is produced by catalytic reaction of methanol and ammonia at elevated temperatures and high pressure: :2 CH3OH + NH3 → (CH3)2NH + 2 H2O Natural occurrence Dimethylamine is found quite widely distributed in animals and plants, and is present in many foods at the level of ...

Adafenoxate
Adafenoxate is a compound related to centrophenoxine, that has been found to act as a nootropic in rats. Synthesis Ex 1: 4-Chlorophenoxyacetic acid (pCPA) 22-88-3is converted to its acid chloride to give 4-chlorophenoxyacetyl chloride 122-68-3(1). Esterification with 2-(1-adamantylamino)ethanol 716-66-3(2) gives Adafenoxate (3) in a single step. Ex 2: Same as above but Fischer–Speier esterification Fischer esterification or Fischer–Speier esterification is a special type of esterification by refluxing a carboxylic acid and an alcohol in the presence of an acid catalyst. The reaction was first described by Emil Fischer and Arthur Speier ... done via a DS-trap. This gives an 88% yield.

Life Expectancy
Life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of its birth, current age, and other demographic factors like sex. The most commonly used measure is life expectancy at birth (LEB), which can be defined in two ways. ''Cohort'' LEB is the mean length of life of a birth cohort (all individuals born in a given year) and can be computed only for cohorts born so long ago that all their members have died. ''Period'' LEB is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year. National LEB figures reported by national agencies and international organizations for human populations are estimates of ''period'' LEB. In the Bronze Age and the Iron Age, human LEB was 26 years; in 2010, world LEB was 67.2 years. In recent years, LEB in Eswatini (formerly Swaziland) is 49, while LEB in Japan is 83.

Headache
Headache is the symptom of pain in the face, head, or neck. It can occur as a migraine, tension-type headache, or cluster headache. There is an increased risk of depression in those with severe headaches. Headaches can occur as a result of many conditions. There are a number of different classification systems for headaches. The most well-recognized is that of the International Headache Society, which classifies it into more than 150 types of primary and secondary headaches. Causes of headaches may include dehydration; fatigue; sleep deprivation; stress; the effects of medications (overuse) and recreational drugs, including withdrawal; viral infections; loud noises; head injury; rapid ingestion of a very cold food or beverage; and dental or sinus issues (such as sinusitis). Treatment of a headache depends on the underlying cause, but commonly involves pain medication (especially in case of migraine or cluster headache). A headache is one of the most commonly experienced ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Muscle Tension
In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state.O’Sullivan, S. B. (2007). Examination of motor function: Motor control and motor learning. In S. B. O’Sullivan, & T. J. Schmitz (Eds), Physical rehabilitation (5th ed.) (pp. 233-234). Philadelphia, Pennsylvania: F. A. Davis Company. It helps to maintain posture and declines during REM sleep. Purpose If a sudden pull or stretch occurs, the body responds by automatically increasing the muscle's tension, a reflex which helps guard against danger as well as helping maintain balance. Such near-continuous innervation can be thought of as a "default" or "steady state" condition for muscles. Both the extensor and flexor muscles are involved in the maintenance of a constant tone while at rest. In skeletal muscles, this helps maintain a normal posture. Resting muscle t ...
