Tricyclic are a family of antidepressants that were given to people before the SSRI. Often psychiatrists prescribe a tricyclic and a newer anti-depressant usually a selective serotonin Inhibitor or a serotonin Norefenefphan selective inhibitor. Your doctor can usual decide what is safe
An example of photoshynthesis is in plants, which are the only organism that can do this system. It's a way for them to get food by the sunlight, which they take in and convert into energy for them.
No. When you are born, you have the most neurons you will ever have. Until you are in your early 20's your brain continues to "trim" neurons from your brain, a mechanism that aids in learning and development. After this point, as you age, you begin to lose neurons, simply from age. After brain development is complete in utero, there are only two locations in the brain that are capable of generating new neurons: the hippocampus (thought to play a role in learning new information) and the olfactory bulb (learning and recognizing new smells).
due its sedating property, wide range of drug-drug interactions and can depress our cognitive functions. It can also induce osteoporosis with prolonged use.
It's preferably to be used in refractory cases of epilepsy only.
Neurotransmitters and hormones work together to form the neuroendocrine system.

An anesthetic state that may be induced if neuroleptic-opiod combination is ineffective. In addition to a neuroleptic and an opioid (droperidol + fentanyl), concurrent administration of 65% nitrous oxide (laughing gas)= patient will be unconscious.
Although levodopa can cross our BBB, but it will be decarboxylated to dopamine peripherally before reaching our CNS - only small amount of Levodopa will be left and available to pass our BBB.
So, instead of giving levodopa in high dose (which can cause lots of side effects), we give levodopa with peripheral decarboxylase inhibitors (e.g. carbidopa, benserazide) which can inhibit decarboxylation of levodopa in GIT and peripheral tissues. (By combining levodopa and peripheral decarobxylase inhibitors, we will have less side effects too)
To make it simple, Levodopa is the precursor of Dopamine and it's used to treat Parkinson's disease. (We don't directly use dopamine because dopamine can't cross our blood-brain-barrier, so, it won't be effective to be taken orally)
monoamine oxidase inhibitors (MAOIs)
The S stands for serotonin and the N stands for norepinephrine and RI stands for reuptake inhibitor. So, obviously these drugs are supposed to work on both serotonin and norepinephrine. However, some literature uses SNRI to mean Selective Norepinephrine Reuptake Inhibitor, and this will work better on norepinephrine. Then you have the SSRI which is Selective Serotonin Reuptake Inhibitor, which works better on serotonin.
We don't give levodopa to:
Tricyclics are more potent antidepressants compared to the newer SSRIs. The reason SSRIs tend to be prescribed more, however, is because tricyclics are less well tolerated due to their antimuscarinic effects, such as: dryness of mouth, constipation, dizziness, abnormal heart rhythm, blurred vision and urinary retention. Trycyclics cannot be given to people with with hypotension or heart problems. SSRIs generally have a longer half life (15-50 hrs vs. 12-32 hrs for trycyclics) and do not require as high a concentration in the blood as tricyclics for their therapeutic effect.
Iodine (a halogen) forms a starch-iodine complex by binding with amylose coils, which results in a transfer of charge between amylose and iodine, changing the energy levels of iodine atoms, and producing a dark blue color.
Tricyclic antidepressants are available only with a physician's prescription and are sold in tablet, capsule, liquid, and injectable forms
If you mean the big spill that just happened, It happened in the gulf of Mexico and started when a BP oil rig caught on fire and sunk into the ocean, which is now spilling oil miles below the sea under water. Gee, thanks BP. Hope this helped!
pyridoxine (vitamin B6) can decrease the effect of levodopa.
