Recent research investigating MDMA has revealed the neurotoxic effect of the drug on brain serotonin neurons. [1] [3] [6] [7] [8] Long term and potentially permanent changes to serotonergic axons have been noted in animal and primate studies where they were administered doses of MDMA similar to those taken by some human users.
In addition, the augmentation of a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor with lisdexamfetamine, a norepinephrine–dopamine releasing agent, recently failed to separate from placebo in phase III clinical trials of individuals with treatment-resistant depression, and clinical development was ...
Dual serotonin and norepinephrine reuptake inhibition resides in different enantiomers for arylthiomethyl morpholine scaffold. [41] Possible drug candidates with dual serotonin and norepinephrine reuptake inhibitory activity have also been derived from piperazine, 3-amino-pyrrolidine and benzylamine templates. [42]
Aaj Tak was the first news channel in India to use OB vans. [5] By the time the channel came into existence, it had a reach of 52 lakh households. It now broadcasts to three crore households and its viewership in news channels is 56%. [4] On 14 December 2018, Aaj Tak launched India's first Hindi high-definition channel, Aaj Tak HD. [2]
The channel was launched in 2003 as a sister channel of the Hindi Aaj Tak news channel. It is one of the four news channels from the TV Today Network stable, the others being Aaj Tak, Tez and Delhi Aaj Tak. [3] Alok Verma was brought in as the Executive Producer to successfully launch TV Today group's foray into the English news channel category.
SSRIs inhibit the reuptake of serotonin. As a result, the serotonin stays in the synaptic gap longer than it normally would, and may repeatedly stimulate the receptors of the recipient cell. In the short run, this leads to an increase in signaling across synapses in which serotonin serves as the primary neurotransmitter.
Serotonin is a neurotransmitter involved in multiple complex biological processes including aggression, pain, sleep, appetite, anxiety, depression, migraine, and vomiting. [10] In humans the effects of excess serotonin were first noted in 1960 in patients receiving an MAOI and tryptophan. [54] The syndrome is caused by increased serotonin in ...
The serotonin transporter (SERT or 5-HTT) also known as the sodium-dependent serotonin transporter and solute carrier family 6 member 4 is a protein that in humans is encoded by the SLC6A4 gene. [5] SERT is a type of monoamine transporter protein that transports the neurotransmitter serotonin from the synaptic cleft back to the presynaptic ...
