small pieces, homogenized with two volumes of 50mMTris buffer (pH 7.4) containing 0.25 Msucrose and 1 mMEDTA, and centrifuged at 700g for 10minutes. After removal of the precipitate (nuclear-debris), the supernatant was further centrifuged at 7,000g for 60minutes. To the resulting sediment (lysosomal-mitochondrial pellet) was added 200ml of cold acetone, and the suspension was stirred for an ho...

regarding to economical importance of kiwi fruit, its wastes such as highly ripe or partially dried up fruits can be used to produce more economically valuable products like fruit leather. therefore, the aim of present study was the effective factor evaluation of kiwi fruit leather production. the samples were studied in two groups, raw and cooked fruits which were treated in a boiling water ba...

The study was aimed to evaluate the carminative and antacid properties of Cucumis sativus fruit pulp aqueous extract under simulated conditions. Fresh fruit pulp of Cucumis sativus was homogenized and dried under shade and thus mass obtained was powdered, weighed and subjected for the evaluation of carminative and antacid profile of the drug. Carminative & antacid properties of Cucumis sativa w...

The aim of this work was to determine 137Cs and 40K radioactivities in soil samples taken from the Babia Góra National Park (BPN) in south Poland. The cluster analysis (CA) and principal component analysis (PCA) were used to discuss the obtained data. 10 cm thick soil cores were collected from the BPN area. Each sample was divided into three sub-samples. The samples were dried, homogenized and ...

AIM The purpose of this study was to develop an improved method for collagen and protein assessment of fibrotic lungs while decreasing animal use. METHODS 8-10 week old, male C57BL/6 mice were given a single intratracheal instillation of crocidolite asbestos or control titanium dioxide. Lungs were collected on day 14 and dried as whole lung, or homogenized in CHAPS buffer, for hydroxyproline ...

To determine salicylate content, 333 food items were analyzed. Foods were homogenized with 25% sodium hydroxide, allowed to stand overnight, acidified with concentrated hydrochloric acid, and then extracted with warm diethylether over 5 hours. The extract was dried and taken up in dilute sodium bicarbonate solution for analysis. Salicylic acid was separated by high performance liquid chromatogr...

introduction cadmium is one of the most important environmental pollutants that can be resulted from different ways. it can easily contaminate soil and water resources. since phosphate ions for stable complexes are available with cations such as pb and cd, so it can cause a decrease in the solubility and mobility of heavy metals in soil. liming is the most widely used treatment that leads to pr...

This paper studies two homogenizations of the down-up algebras introduced in [1]. We show that in all cases the homogenizing variable is not a zero-divisor, and that when the parameter β is non-zero, the homogenized down-up algebra is a Noetherian domain and a maximal order, and also Artin-Schelter regular, Auslander regular, and Cohen-Macaulay. We show that all homogenized down-up algebras hav...
