Cold Autoimmune Hemolytic Anemia with Auto-Anti-Ai Specificity: 51 Chromium Survival Studies

" Abstract A 65-year-old woman was found to have serious autoimmune hemolytic anemia. The patient was group A 1 Rh 0 positive. The direct antiglobulin test was highly positive with anti-C3 and negative with anti- IgG. An eluate disclosed anti-AI and a weak anti-L Sequential 5 \ u2019Chromium survival research studies were done with group OI and Al red cells. The group OI red cells endured normally while the group A J red cells were removed in a \ u201ctwo- element \ u201d pattern attribute of IgM complementfixing antibodies. ".

Stimulation of Antibody Following 51 Chromium Survival Studies

" Abstract The survival of red blood cells radiolabeled with 51 chromium is a reliable technique for forecasting transfusion compatibility. About 1. 0 ml of 51 Cr labelled RBCs is infused into the patient and examples are drawn at fixed intervals post in-fusion to determine RBC survival. To research this concern, blood examples were accumulated from six patients with a single irregular doantibody, 7 to 9 months after 5lCr RBC survival studies had been carried out in unassociated procedure. Lotion antibody titers showed a considerable increase in 2 of 6 patients and antibody rating was significantly increased in 3 of 6 patients. This research suggests that 5l Cr survival tests using small volumes of RBCs can promote substantial increases in antibody in some patients, a variable that needs to be considered in executing these tests and in planning subsequent transfusions.

A comparison of the monocyte monolayer assay with 51 chromium red cell recovery for determining the clinical significance of red cell alloantibodies

" Abstract The 51 chromium red cell recovery research study is a trustworthy measure of transfusion compatibility. One anti-K1 that caused reasonably sped up red cell devastation had a negative MMA. Four control subjects without atypical antibodies had normal autologous RBC 51 Cr healings and were negative by the MMA technique. The MMA test can be a trusted forecaster of in vivo antibody actions and an appropriate option to 51 Cr recovery research studies. ".

Zinc-Chromium oxide catalyst for gas-phase ketonisation of pentanoic acid

" Oxides of Zinc and Chromium mixed driver with different atomic proportions of Zinc and Chromium were tested in the ketonisation of pentanoic acid in the gas phase. It was found that Zn-Cr with an atomic ratio provided the best catalytic efficiency in comparison with other oxides with higher or lower atomic proportion of Zn and Cr mixed oxides, ZnO and Cr2O3.

Corrosion Behavior of Various 13 Chromium Tubulars in Acid Stimulation Fluids

" Abstract The oil sector has used 13 Chromium materials in oil and gas wells for many years. These tubular materials additionally challenge the rust inhibitor modern technology applied in acid stimulation fluids. There are many publications associated with acidizing wells finished with 13Cr tubulars; however, pertaining to rust actions of enhanced 13Cr materials in stimulation fluids, very little details has been released. This paper offers outcomes of acid corrosion tests done on numerous 13Cr examples from 2 producers at temperatures from 180 \ u00b0F to 312 \ u00b0F and from 6 to 30 hours of exposure. Results show that rust actions of enhanced 13Cr in acids can be entirely different from that of 13Cr depending on an inhibitor bundle used, and that strength of the material plays a substantial role in deterioration actions. Likewise, the information shows that some prevention packages typically used for 13Cr do not provide adequate corrosion defense on improved 13Cr materials. ".

Reaction Kinetics of the Uptake of Chromium(III) Acetate by Polyacrylamide

" Abstract Gelled polymer therapies applied in shot and production wells are used to modify fluid circulation in oil tanks to ensure that oil production is increased and water production is decreased. A common gel used in field treatments is made by crosslinking partly hydrolyzed polyacrylamide with chromium acetate. ".

Effect of Composition of a Polyacrylamide-Chromium(III) Acetate Gel on the Magnitude of Gel Dehydration and Disproportionate Permeability Reduction

" Abstract For some polymer gels applied in reservoirs to regulate water flow, a beneficial out of proportion leaks in the structure reduction takes place in which permeability to water is decreased to a much greater level than to oil. For the variety of criteria researched, the reduction of leaks in the structure to water and oil and the DPR were strong functions of gel make-up and used pressure gradients, although gel dehydration volumes varied by only a small quantity.

Effects of dietary supplementation of chromium methionine chelate on growth performance, oxidative stress, hematological indices, and carcass traits of broiler chickens

" Abstract This research was performed to review the nutritional effects of chromium methionine chelate on development performance, oxidative stress criteria, blood biochemistry, and carcass attributes of broiler poultries. An experiment was performed on 34,000 1-day-old straight-run broiler chicks at a commercial farm. The chicks were separated arbitrarily into 3 groups; the first group consisted of 17,000 birds, which used as a control, whereas the 3rd and second groups was composed of 7000 and 10,000 birds, respectively, with 5 duplicates per group. It was found that Cr-Meth enhanced the body weight, weight gain, feed intake, and feed conversion ratio of broilers. The chelated chromium can relieve the oxidative condition of birds by increasing the plasma glutathione peroxidase task and minimizing the serum malondialdehyde level. It was observed that the effects of 100 g/ton Cr-Meth chelate on performance indices, death rate, and oxidative stress parameters were better than that of 50 g/ton inclusion rate. Supplements of Cr-Meth increased the total protein level, but reduced the glucose, complete cholesterol, and triglyceride focus in the blood serum. In enhancement, it increased the carcass yield and reduced the abdominal fat portion of the birds \ u2019 carcass. Therefore, chromium can be included in diet plans of broilers at a rate of 200 to 400 ppb, and the higher concentration was more reliable than the lower one. It can be suggested to use Cr-Meth chelate in broiler diet regimens at 100 g/ton to improve the efficient efficiency and lower the oxidative stress of birds. ".

Hexavalent chromium mobility in a high amorphous phase Chromite Ore Processing Residue (COPR) in the perspective of a chromium remediation treatment

" The mineralogical and chemical composition of chromite ore processing residue from a site in the north of France was investigated. Literary works information on most examined COPR materials enabled establishing a category of the materials into high calcium/low silica, intermediate and low calcium/high silica classifications. This calcium \ u2013silica relation is a measure of the quality of the initial ore and the geochemical changes having occurred in a COPR deposit over time, compared to fresh COPR created from pure ore, and perhaps the post-deposit admixture of other waste materials. Extraction of leachable Cr from COPR generates formation of a new chemical equilibrium in the material with a recharge in mobile chromium as a result of dissolution of concrete phases. Removal of leachable Cr is not an appropriate removal technique because it will not allow to take out the strong bound Cr from the material in a solitary treatment. ".

Effect of Chromium Species and Plant Growth Promoting Microorganisms on Growth Parameters of Amaranthus gangeticus

" A pot experiment was performed in the existing study to assess the impact of hexavalent and trivalent chromium under the influence of bacteria on Amaranthus gangeticus growth characteristics. Nine different focus of chromium were used which consists of 0, 50, 100, 150, and 200 mg/kg Cr +6 as K2Cr2O7 and 50, 100, 150, and 200 mg/kg Cr +3 as KCr2, in conjunction with 4 different levels of microbes, containing control, Azospirillum, Phosphate solublizing Bacteria, and Potassium Releasing Bacteria.
