On dentin: I believe what you're asking is where is it placed. Calcium hydroxide is usually placed in the area where the decay was closest to the nerve (pulp) of the tooth. Calcium hydroxide will help build up a barrier between the nerve and filling. There are some better materials in use now besides calcium hydroxide. ...Read moreSee 1 more doctor answer

Neither.: It is a nitrogen rich plastic frequently added to food products to artificially boost protein assays because of its nitrogen content. Avoid! the chinese infant formulas and pet foods have had scandals in the past for putting this in said material! it is toxic! can cause a myriad of problems, particularly renal problems! ...Read more
DNA: Genes are made up of nucleic acids called DNA. Those genes are then transcribed into amino acid sequences called proteins. The dystrophin gene is much too large to spell out in a DNA sequence, and its protein is much too large to spell out in an amino acid sequence. Here is a link to some more information on the gene. http://www.ncbi.nlm.nih.gov/gene/1756 ...Read moreSee 2 more doctor answers
DoesPrazosin/other alpha blocks act on non-vascular smooth muscle e.g. the throat?If sudafed is alpha stim and contricts nasal,wouldnt it make sense?
Good question: Alphablockers used to treat hypertension seem to be specific for their action on arteriolar musculature as far as I can tell clinically. Sudafed constricts smooth muscle in vessel walls, but can stimulate smooth muscle in the lower urinary tract and cause urinary retention at times. A pharmacologist would be best qualified to answer your question however. ...Read more
Excitatory: Histamine is actually classified as an excitatory neurotransmitter in the brain responsible for the sleep wake cycle. Too much of it can keep you awake. That is why it is used in many commercial sleep aides seen with the letters "pm" attached to some kind of pain killer. A common side-effect of a histamine blocker like Diphenhydramine (benadryl) is drowsiness. ...Read more

Is it real that januvia (sitagliptin) 100mg made pancreas cells produce more insulin ( made beta cells more active )?
Incretin: Januvia (sitagliptin) is an incretin which inhibits the breakdown of an enzyme called dpp-4. Dpp-4 breaks down glp-1. Glp-1 stimulates Insulin and inhibits glucagon (which raises glucose). Inhibition of glp-1 breakdown means it can stimulate more Insulin and inhibit more glucagon. ...Read more
Between Allegra and Desloratadine, which drug has less blood-brain barrier permeability and is less anticholinergic?
Allegra: Fexofenadine and loratadine, allegra and claritin, respectively, are the least sedating of all anti-histamines according to a recent NIH review. All anti-histamines cross the blood brain barrier to some extent. The real issue is sedation and allegra and claritin appear to win the context. They are also less anticholinergic than many others. ...Read more
Names say it all: Angiotensin converting enzyme(ace) inhibitor vs angiotensin receptor blocker(arb). The names really say it all. Angiotensin which raises blood pressure needs to be activated to work. Aces prevent that activition. Arbs directly block the activity of angiotensin. Both have similar effects but there is more evidence for heart protection with aces than arbs but slightly more side effects with aces. ...Read more

Which ingredient is the best way fight wrinkles? Retinol, peptides, collagen, stem cells, plancenta, amino acids or vitamin C
Growth factors: We have known since the 70s that retinoids and retinols are great collagen stimulators (which equals wrinkle fighters). In this century, we developed collagen growth factors which are derived from actual human skin and are necessary for collagen to thrive, thus reducing and eliminating wrinkles. Note i did not say "appearance of wrinkles". Skinmedica is my favorite product to contain these. ...Read moreSee 1 more doctor answer
