Validated RP-HPLC method for the simultaneous determination of glucosamine sulphate and curcumin in cream formulation: A novel stability-indicating study

Purpose: To develop and validate a stability-indicating reverse phase-high performance liquid chromatography (RP-HPLC) method for the simultaneous determination of glucosamine sulphate (GS) and curcumin (Cur) in drug solution and formulation.Methods: The optimized chromatographic conditions were achieved by passing various compositions of mobile phases over  different reverse phase chromatographic columns. Various validation parameters, including linearity, range, limit of detection (LOD), limit of quantification (LOQ), accuracy, precision, specificity and system suitability were performed and evaluated. Stability studies under stressed conditions were done to evaluate the effects of acid, alkali, oxidation, heat and degradation by UV light.Results: The validated method was linear over the concentration range of 0.094 to 1.5 mg/mL for GS and 0.125 to 1.5 mg/mL for Cur, with a correlation coefficient > 0.999. The Intra and inter-day precision were 1.9 % for GS and 0.5 % for Cur, while accuracy was 96 and 102 % for GS and Cur, respectively. Stability studies showed that GS was highly sensitive to acid, alkali and oxidation and less sensitive to heat and UV. Cur was stable against acid, heat and oxidation but sensitive to alkali and UV.Conclusion: The developed and validated method was precise and accurate for both GS and Cur and can potentially be utilized for their identification and quantification at industrial, research and quality control laboratories

Anemia Of Chronic Disease And Kidney Failure

Anemia is a disease that caused due to inflammation, autoimmune disease, or chronic disease as cancer, kidney failure, heart failure, diabetes, but the main reason of anemia is iron deficiency. Breathlessness, weakness, and exhaustion are all possible effects of anemia. Anemia comes in a variety of types. Everyone has a unique reason. Anemia may be chronic or transient. It could be minor or really serious. Anemia may indicate a more serious medical condition.  In this research we will explain the anemia due to chronic disease especially kidney failure. Anemia occurs when decreasing the number of red blood cells that carry oxygen to the body. According to world health organization (WHO), the person has anemia when hemoglobin (which is present in red blood cells, transports oxygen from the lungs to every other organ in the body), (Hb) levels <12.0 g/dl in women and <13.0 g/dl in men. We can treat anemia by iron supplement, medications, blood transfusion, vitB12, blood and bone transplant but it occur in hospital and by healthy diet. If anemia remained untreated it will be a risk of irregular heartbeat, heart failure, infection, and in children it may cause developmental delay. We can diagnosis anemia by blood tests which are used by medical practitioners to look for indications of inflammation-related anemia, other anemias, or other health issues. You will give blood to a medical professional who will then submit the sample to a lab for analysis. The National institutes of health (NIH) approved that we can examine a variety of components and characteristics of your blood, such as how many red blood cells ,the dimensions of red blood cells ,how much hemoglobin is present in your blood and red blood cells ,the quantity of reticulocytes, or growing red blood cells, in your blood. Blood tests are another tool that a medical expert may use to measure how much iron is stored in blood, transferrin, and ferritin. If the results of a blood test indicate that you have anemia low blood iron levels will appear, determining the amount of iron in low and normal range. Adults who suffer from severe anemia may become vulnerable to heart or lung issues. For instance, you might experience heart failure, in which the heart is unable to pump enough blood throughout your body at the proper pressure or tachycardia, which is an unusually rapid heartbeat. Anemia  can also come from obesity unlike exception of some people so we should follow health diet has iron supplement such as meat, sugar beet

ON-LINE MEASUREMENTS OF OXIDATION OF CARBON USING VISIBLE SPECTROSCOPY

We have identified four different band heads belonging to the B1 Σ-A1 Π bands of the Angstrom system of the CO spectrum in the visible region at λ = 561.0, 519.8, 451.1 and 439.3 nm, for on-line monitoring of conversion of carbon to carbon monoxide in the ‘de-coking’ process of a ‘coked’ catalyst. A low-power glow discharge in oxygen gas was used as a source for oxidizing carbon from a ‘coked’ zeolite catalyst. Evolution of CO as a function of time was systematically monitored using the 451.1 nm band head since there is no overlap with any possible impurities including oxygen, nitrogen or water vapor. An interesting observation is an exponential increase in the evolution of CO typically after about 10 minutes from the initiation of the discharge. The results may be of particular interest in monitoring catalyst regeneration on-line as well as environmental monitoring of CO

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum
