Food bank
A food bank (or foodbank) is a non-profit, charitable organization that aids in the distribution of food to those who have difficulty purchasing enough to avoid hunger. Food banks tend to run on different operating models depending on where they are located. In the U.S., Australia, and to some extent in Canada, foodbanks tend to perform a warehouse type function, storing and delivering food to front line food orgs, but not giving it directly to hungry peoples themselves. In much of Europe and elsewhere, food banks operate on the front line model, where they hand out parcels of uncooked food direct to the hungry, typically giving them enough for several meals which they can eat in their homes. In the U.S and Australia, establishments that hand out uncooked food to individual people are instead called food pantries, food shelves or food closets. In Less Developed Countries, there are charity-run food banks that operate on a semi-commercial system that differs from both the more common "warehouse" and "frontline" models. In some rural LDCs such as Malawi, food is often relatively cheap and plentiful for the first few months after the harvest, but then becomes more and more expensive. Food banks in those areas can buy large amounts of food shortly after the harvest, and then as food prices start to rise, they sell it back to local people throughout the year at well below market prices.
Chloroprocaine (pKa 8.7) is the drug of choice for epidural analgesia and a decompensating fetus, because it does not participate in ion trapping. Placental transfer of 2-chloroprocaine is not influenced by fetal acidosis.The in vitro half-life of chloroprocaine is 21 seconds for maternal and 43 seconds for fetal blood. In patients who are homozygous atypical for plasma cholinesterase, chloroprocaine typically exists for two minutes in circulation. Synthesis
The hydrochloride salt of 4-amino-2-chlorobenzoyl chloride is made by the reaction of 2-chloro-4-aminobenzoic acid with thionyl chloride. Synthesis of this drug is then accomplished by directly reacting the product of the last step with the hydrochloride salt of 2-diethylaminoethanol. References
