    junction, the slow emptying of barium and absence of peristalsis are characteristics of achalasia (Allaix, et al, 2016). The barium swallow defines the shape of the oesophagus and lower oesophageal sphincter (LES) and may also show increased peristalsis and spasm trying to overcome the LES that does not relax. This condition is called vigorous achalasia (Fisichella, Raz, Palazzo, Niponmick, Patti, 2008). Oliveira, et al (1997) reported that in some cases, the barium oesophagram may not present…

    the metals were. Continuing, we also noticed that part A and B differed in terms of what the unknown metals turned out to be for each one. Part A's unknown metal eventually was found to be beryllium, while part B's unknown metal was determined to be Barium. In closing, after following the steps and performing the calculations using the formulas we were able to determine that the two unknown metals were Beryllium and…

    Reaction # Observations Equation 1 We mixed Aluminum Sulfate with Barium Nitrate in two test tubes. The Barium Nitrate is a clear liquid that had no smell. The Aluminum Sulfate also was a clear liquid with no scent. When mixed, the center of the liquid turned into a milky white precipitate. After 2 minutes the white substance sank to the bottom while the clear liquid sat on top. Al2(SO4)3(aq)+3Ba(NO3)2(aq)--> 2Al(NO3)3(aq)+3BaSO4 (s) 2 First we felt the material of a piece of Magnesium.…

    has atomic number of 38. It is an alkaline earth metal, and is a soft white yellowish metallic element which has highly reactivity chemically. It’s properties are mostly intermediate between aand similar to those of its group neighbors calcium and barium. When it is exposed to air, the metal forms a dark oxide layer. Strontium has 38 protons, 50 neutrons, and 38 electrons. The electron configuration of Strontium is 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(10) 4s^(2) 4p^(6) 5s^(2) or [Kr] 5s^(2).…

    When hydrochloric acid was added to the unknown and known solutions, both resulted in no reaction. This also occurred when potassium hydroxide was added to both of the solutions. Barium chloride was then added to the two solutions, which resulted in a cloudy white precipitate from both of the solutions. A cloudy white precipitate also formed when calcium nitrate and ammonium nitrate were added to both the unknown and known solutions…

    ACHALASIA Achalasia refers to a rare disease of the muscle of the lower esophageal body and the lower esophageal sphincter (LES) that prevents relaxation of the sphincter and inability of the muscles to contract, or absence of peristalsis, of the esophagus. LES pressure and relaxation are regulated by excitatory and inhibitory neurotransmitters however, patients with achalasia lack these nonadrenergic, noncholinergic inhibitory ganglion cells thus, causing imbalance between the excitatory and…

    identified as zinc carbonate due to evolution of CO2 on addition of sulphuric acid. Among the soluble solids, two (1 and 12) formed precipitates in sulphuric acid. One was expected to be Barium chloride and to react with silver nitrate. Hence, (14) and (13) were reacted with 1 and 12. This led to the identification of 1 as barium chloride and 13 as silver…

    doctors may rather perform an endoscopy. In this procedure, the doctor inserts a tube with a tiny camera on the end into the esophagus to look for problems. Another diagnostic method is a barium swallow. If you have this test, barium is prepared in liquid form. The doctor will then monitor the movement of barium down your esophagus with the help of X-rays. Treatment: Treatments for achalasia include: 1. Oral medications, 2. Stretching of the lower esophageal sphincter (dilation), 3. Surgery to…
