52 [vol. 6, THE DISTRIBUTION OF PHOSPHORUS IN COW'S MILK AND THE SCHEME FOR THE SEPARATION OF PHOSPHATIDES By Rinjiro SASAKI (From the Institute of Agricultural Chemistry, College of Agriculture, Tokyo Imperial University) (Received 9th September 1930) A. The Distribution of Phosphorus in Cow's milk In order to extract the phosphatides, it is necessary first to determine the distribution of phosphorus in cow's milk. Liquid milk can not be extracted with ether or with other organic solvents owing to its large content of water. The substance applied in this experiment is the milk powder, dried by the Buflovak drum drier below 70•Ž. Its content of moisture is 4.498%, deter mined by the method of drying in the air bath of 105•Ž. The content of total phosphorus was determined(5) in the ash of sample which was burned with a little of fusing mixture. In 100g. of milk powder In 100g. of dry matter Total phosphorus 0.745g. 0.781g. The amounts of phosphorus, which are soluble in the various organic sol vents, were determined by extracting with three solvents in the following orders. (A) Ether-Acetone-Alcohol (B) Acetone-Ether-Alcohol (C) Alcohol-Ether-Acetone Experiment (A) 1) At first a pair of each 10g. of sample was extracted with ether by the Soxhlet's apparatus for a week. After the extraction had been comp leted, the extract was freed from ether and weighed. In 100g.of milkpowder In 100g.of dry matter Total ether matters soluble 3.609g. 3.779g. 2) The above extract was dissolved in a very little of ether. -

METASTABILITY of CADMIUM SULFATE and ITS EFFECT on ELECTROMOTIVE FORCE of SATURATED STANDARD CELLS by George W
U. S. DEPARTMENT OF C OMMERCE NATIONAL BUREAU OF STANDARDS RESEARCH PAPER RP1389 Part of Journal of Research of the National Bureau of Standards, Volume 26, May 1941 METASTABILITY OF CADMIUM SULFATE AND ITS EFFECT ON ELECTROMOTIVE FORCE OF SATURATED STANDARD CELLS By George W. Vinal and Langhorne H. Brickwedde ABSTRACT Both solubility and electromot ive force measurements are concordant in fixing the transition temperature of CdSOf.8/3HzO to CdSOf.HzO, at 43.4°C. Previously the transition temperature was genera.lly believed to be 74° C. Cells recently were made with each modification. Their respective electromotive forces differ except at the transition temperature, where they, as well as the solubilitiesJ are equal. The temperature coefficient of cells containing CdSO•. HzO was founa to be positive, whereas the temperature coefficient for cells containing the ordi nary salt CdS04.8/3HzO is negative, as is well known. Both hydrates tend to persist in a metastable state, and measurements can be made over a wide range of temperatures. The free energy changes of the cells are discussed, and some practical applications for the cells are described. CONTENTS Page I.

Particularly Hazardous Substances
Particularly Hazardous Substances In its Laboratory Standard, OSHA requires the establishment of additional protections for persons working with "Particularly Hazardous Substances" (PHS). OSHA defines these materials as "select" carcinogens, reproductive toxins and acutely toxic materials. Should you wish to add: explosive, violently reactive, pyrophoric and water-reactve materials to this category, the information is included. Carbon nanotubes have also been added due to their suspected carcinogenic properties. This table is designed to assist the laboratory in the identification of PHS, although it is not definitively conclusive or entirely comprehensive. *Notes on the proper use of this table appear on page 12. 1 6 5 2 3 4 Substance CAS National Toxicity National Program Carcinogen Toxin Acute Regulated OSHA Carcinogen Group IARC Carcinogen Toxin Reproductive Violently Reactive/ Explosive/Peroxide Forming/Pyrophoric A-a-C(2-Amino-9H-pyrido[2,3,b]indole) 2648-68-5 2B Acetal 105-57-7 yes Acetaldehyde 75-07-0 NTP AT 2B Acrolein (2-Propenal) 107-02-8 AT Acetamide 126850-14-4 2B 2-Acetylaminofluorene 53-96-3 NTP ORC Acrylamide 79-06-6 NTP 2B Acrylyl Chloride 814-68-6 AT Acrylonitrile 107-13-1 NTP ORC 2B Adriamycin 23214-92-8 NTP 2A Aflatoxins 1402-68-2 NTP 1 Allylamine 107-11-9 AT Alkylaluminums varies AT Allyl Chloride 107-05-1 AT ortho-Aminoazotoluene 97-56-3 NTP 2B para-aminoazobenzene 60-09-3 2B 4-Aminobiphenyl 92-67-1 NTP ORC 1 1-Amino-2-Methylanthraquinone 82-28-0 NTP (2-Amino-6-methyldipyrido[1,2-a:3’,2’-d]imidazole) 67730-11-4 2B -
Inorganic Chemistry Test for Cadmium Radical
Chemistry Inorganic Chemistry Test for Cadmium Radical General Aim Method Detection of the presence of cadmium ion as a base Detection of the presence of cadmium as a base radical radical in inorganic salts such as cadmium sulfate. using specic chemical reagents. Learning Objectives (ILOs) Dene and dierentiate between members of the second group cations and those of other cation groups. Classify inorganic salts according to their base radicals. Compare between cadmium containing salts and other members of the same group in terms of chemical structures, properties and reactions. Identify cadmium radicals containing salts experimentally. Select the appropriate reagents to detect the presence of cadmium radical. Balance the chemical equations of chemical reactions. Theoretical Background/Context Cadmium (Cd) is one of the transition metals that are located in the d-block of the periodic table. Cadmium is located in the fth period and twelfth group of the periodic table. Cd possesses an atomic number of 48 and an atomic mass of 112.411g. It was rst discovered by the German scientist, Friedrich Strohmeyer in 1817 in Germany. At that time, cadmium was commonly used to protect iron and steel from corrosion as it was inserted as a sacricial anode. Additionally, it was used in the manufacture of nickel-cadmium batteries. Cadmium is a highly toxic element so it has to be handled with great caution. Abundance of Cadmium in Nature Cadmium cannot be easily found in its elemental form naturally. It has been detected in the Earth's Crust in very minute amounts that do not exceed 0.1 to 0.2 ppm. -

Abstract Background and objectives: Sargassum angustifolium is a brown alga in southwestern coastline of Persian Gulf. Regarding the presence of various bioactive compounds and evidence of antihypertensive effects in other species of Sargassum, we evaluated the effect of S. angustifolium ethanol extract in CdCl2-induced hypertension in Wistar rats. Methods: Alga extract was prepared by maceration method using 70% ethanol and assessed for total phenolics and salt content. CdCl2 (1.5 mg/kg/day) was administered intraperitoneally to the rats for two weeks. Treatment groups received S. angustifolium extract (20, 40 and 80 mg/kg) or nifedipine (10 mg/kg) orally and simultaneously were given CdCl2 for two weeks. Systolic blood pressure (SBP) and heart rate were measured using tail-cuff method. Total antioxidant capacity, urea, creatinine, electrolytes including sodium, potassium, calcium and chloride were estimated in blood samples. The weight and histopathology of kidney tissues were also evaluated. Results: The content of total phenolic as gallic acid equivalent and the salt as NaCl was 67.42 ± 9.5 mg/g and 6.9 g/100 g in dried ethanol extract, respectively. -
