Spirits are to be sold only in the state owned Fine Wine and Good Spirits stores, which also sell wine, but not beer. Prices are generally the same throughout the state, but state stores may offer special discounts and sales, and county sales tax may cause the price to differ slightly. People under the age of 21 are allowed to enter Fine Wine and Good Spirits stores, contrary to popular belief, but only if accompanied by a parent or guardian. Monday through Saturday, a store may open as early as 9 am and close as late as 10 pm. On Sunday, many stores sell liquor from 11 am until 7 pm.
 Question: can you buy beer on sunday in pa Context: The Sheriff of Nottingham was historically the office responsible for enforcing law and order in Nottingham and bringing criminals to justice. For years the post has been directly appointed by the Lord Mayor of Nottingham and in modern times, with the existence of the police force, the position is entirely ceremonial and sustained to boost tourism due to the legendary connection with the fictional Sheriff of Nottingham in the tales of Robin Hood. However the historical position goes back to Anglo-Saxon times. The office is sometimes confused with that of the High Sheriff of Nottinghamshire (that office had previously existed, from 1068 until 1568, as High Sheriff of Nottinghamshire, Derbyshire and the Royal Forests.)

In this sense of the word, antihistamines are subclassified according to the histamine receptor that they act upon. The two largest classes of antihistamines are H-antihistamines and H-antihistamines. Antihistamines that target the histamine H-receptor are used to treat allergic reactions in the nose (e.g., itching, runny nose, and sneezing) as well as for insomnia. They are sometimes also used to treat motion sickness or vertigo caused by problems with the inner ear. Antihistamines that target the histamine H-receptor are used to treat gastric acid conditions (e.g., peptic ulcers and acid reflux). H-antihistamines work by binding to histamine H receptors in mast cells, smooth muscle, and endothelium in the body as well as in the tuberomammillary nucleus in the brain; H-antihistamines bind to histamine H receptors in the upper gastrointestinal tract, primarily in the stomach.
 Question: is histamine an agonist for h1 and h2 receptors Context: Gestation in a dog is 63 days in length, if measured from the day of ovulation. Since it is difficult to determine the exact date of ovulation, errors are often made in calculating gestation period. Canine sperm can live for 10 to 11 days in the uterine tubes (fallopian tubes) so if a female is bred 10 days before the oocytes (eggs) can be fertilized, she will appear to have a gestation length of 70 days. If she is bred on the day the oocytes can be fertilized, her gestation length will appear to be 60 days long.
