The Impact

Alkaline water is in the focus of scientific interest over the last decade, due to its ability to alkalize the organism as well as its antioxidant effect. The aim of our research is to determine the impact of ionized water by adding enzymatic and non-enzymatic antioxidants, glutathione and vitamin C, during hyperthermic stress, on the concentration of total proteins. The experiment performed on a white laboratory Wistar rats, a female sex, weighing 180-220 g, young rats, divided into three groups of 15 individuals. Oxidative stress was caused by acute hyperthermic exposure at 41˚C. The first group is the control group (KPM), the second group is treated with ionized water (TAM), and the third group with ionized water with added glutathione and vitamin C (TAD). The duration of treatment lasted 21 days. Acute hyperthermic exposure caused a significant difference in total protein concentration between the 7th and 14th day taken as the starting points and the 21st day of treatment, respectively, on the day of hyperthermic exposure of rats. Such a significant difference was observed in the KPM and the TAM group (p <0.001), whereas the TAD group is an exception where no statistically significant difference was observed in the same period (p> 0.05). Animals treated with ionized water on day 14 showed a significantly higher total protein concentration (p <0.01) compared to the group receiving only natural water, which is consistent with the finding obtained by comparison between the KPM and TAD group at 21st day where the difference is also statistically significant (p <0.05). The acute application of the treatment with ionized water, without or in combination with other antioxidants, in the absence of hyperthermic stress does not lead to a significant alteration in protein concentration. The hyperthermic exposure intensifies the production of oxygen radicals and the potential for oxidative modification of proteins and molecules with a protein structure. Individual action of ionized water as well as synergism with the added antioxidants caused a high protective effect on oxidative damage. Because of this, the effect of oxidative cleavage is less pronounced in rats treated with ionized water and antioxidants because they have a stronger antioxidant defense that prevents oxidative modification of proteins and all biomolecules in the body.

Experiments were conducted on five chronically instrumented unanesthetized sheep to determine the effects of sustained hypoproteinemia on lung fluid balance. Plasma total protein concentration was decreased from a control value of 6.17 +/- 0.019 to 3.97 +/- 0.17 g/dl (mean +/- SE) by acute plasmapheresis and maintained at this level by chronic thoracic lymph duct drainage. We measured pulmonary arterial pressure, left atrial pressure, aortic pressure, central venous pressure, cardiac output, oncotic pressures of both plasma and lung lymph, lung lymph flow rate, and lung lymph-to-plasma ratio of total proteins and six protein fractions for both control base-line conditions and hypoproteinemia base-line conditions. Moreover, we estimated the average osmotic reflection coefficient for total proteins and the solvent drag reflection coefficients for the six protein fractions during hypoproteinemia. Hypoproteinemia caused significant decreases in lung lymph total protein concentration, lung lymph-to-plasma total protein concentration ratio, and oncotic pressures of plasma and lung lymph. There were no significant alterations in the vascular pressures, lung lymph flow rate, cardiac output, or oncotic pressure gradient. The osmotic reflection coefficient for total proteins was found to be 0.900 +/- 0.004 for hypoproteinemia conditions, which is equal to that found in a previous investigation for sheep with a normal plasma protein concentration. Our results suggest that hypoproteinemia does not alter the lung filtration coefficient nor the reflection coefficients for plasma proteins. Possible explanations for the reported increase in the lung filtration coefficient during hypoproteinemia by other investigators are also made.

Abstract Abstract 1738 Sipuleucel-T is an autologous cellular immunotherapy for the treatment of asymptomatic or minimally symptomatic metastatic castrate resistant prostate cancer. Sipuleucel-T consists of autologous peripheral blood mononuclear cells (PBMCs), including antigen presenting cells (APCs), that have been activated with a recombinant human protein, PAP-GM-CSF (prostatic acid phosphatase [PAP] linked to granulocyte-macrophage colony-stimulating factor [GM-CSF]). It is prepared from cells collected by leukaphereses at Weeks 0, 2, and 4 and infused approximately 3 days following each leukapheresis. In the IMPACT study, 512 patients were randomized (2:1) to sipuleucel-T or control (non-activated autologous PBMCs). Serum samples were collected at Baseline and Weeks 6, 14, and 26, and were analyzed for routine clinical chemistry tests in a comprehensive metabolic panel, which included total protein and albumin. In selected samples, serum protein electrophoresis (SPEP) and densitometry were performed using the Sebia automated electrophoresis system. We observed elevated total protein at Weeks 6 and 14 in sipuleucel-T patients only. At Week 6, 10.0% (28/279) of sipuleucel-T patients with a normal baseline total protein concentration had an elevated total protein concentration (upper limit of normal [ULN] = 7.9 to 8.5 g/dL, depending on age) compared with 0% (0/140) of control patients. At Week 14, 10.4% (19/183) of sipuleucel-T patients with a normal baseline total protein had an elevated total protein compared with 0% (0/86) of control patients. Albumin levels were not elevated at Week 6 following treatment (0.4% ½84 of sipuleucel-T patients with a normal baseline albumin concentration had increases in post-treatment serum albumin), indicating that the changes in total protein were due to elevations in serum globulin. In sipuleucel-T patients, there was a positive correlation between the maximum globulin protein elevations (total protein minus albumin) and the magnitude of antibody titers to PAP-GM-CSF at Week 6 (n = 126; P = 0.001) and Week 14 (n = 85; P = 0.002). Samples from sipuleucel-T patients for whom both a baseline and post-treatment sample were available and who fell within the upper 10th percentile of the total protein change (n = 13) were evaluated by SPEP. All of these patients had increased gamma globulin compared with baseline. Nine patients (69.2%) developed gamma globulin above the upper limit of normal (i.e., > 1.5 g/dL) which was not present at baseline. A correlation between gamma globulin elevations and antibody titers to PAP-GM-CSF in these patients (n = 9) was observed at Week 6 (r = 0.664, P = 0.051). These data demonstrate that elevated gamma globulin levels can develop following treatment with sipuleucel-T and were associated with the development of an antigen-specific humoral response.

The standard curve of a typical colorimetric assay for total protein is often nonlinear and dependent on the albumin fraction of the protein standard. We developed a simple mathematical transformation to make the standard curve linear and a computational method to correct for differences in albumin concentrations among the samples. This method uses data from total protein assays on two sets of standards (albumin and gamma globulin) and provides accurate measures of total protein over the full range of albumin fractions. Comparison of this two-standard method with the a method that uses only albumin as a standard shows that this method prevents physiologically significant overestimations in total protein concentration and calculated protein osmotic pressure differences in the lungs.

Background: On March 11, 2020, the World Health Organization (WHO) announced the Coronavirus outbreak officially as a pandemic. This pandemic has led to new measurements to prevent viral spread. The measures included decreasing the person’s mobility outside homes with subsequent changes in the lifestyles, particularly in physical activity and eating habits. It has been noticed that consumption of some vitamins may help in preventing or reducing the symptoms of viral infection. Those vitamins include vitamin C, D and zinc. There is a common observation that the general public believes that the use of vitamins, especially vitamins C, D and zinc, reduces the chance of acquiring COVID-19. Objectives: The aim of this study was to determine the impact of COVID-19 pandemic on taking vitamins supplements by the Saudi general population in order to explore their believes regarding the protective value of these vitamins against COVID-19 infection. Subjects and Methods: This cross-sectional study was conducted using a self-administrated questionnaire that was designed, uploaded to the Google form and distributed online to the general Saudi population through the social media (Whatsapp, Twitter) as well as through email between August and December 2020. Statistical Packaged of Social Sciences program (SPSS) for Windows (version 17.0., Chicago: SPSS Inc) was used to analyze the data. A significant difference was considered when the p value is < 0.05. Student t-test and Chi-square (χ2) test were used to compare the studied variables as appropriate. Results: A total of 1043 participants were included in this study (64.9% females, 35.1% males). The mean age for them was 35.3±14.78 years. Only 9.3% (97 participants) were diagnosed to have COVID-19. About 28% of the participants were in contact with COVID-19 cases. Among participants diagnosed to have COVID-19 infection, (13% versus 29%) were taking vitamin C and (2% versus 15%) were taking zinc supplements daily during the 6 months before and after the pandemic, respectively, while (20% versus 25%) were taking vitamin D supplements weekly during the 6 months before and after the pandemic, respectively. Among participants who were in contact with COVID-19 cases, (8% versus 20%) and (3% versus 11%) were taking vitamin C and zinc supplements daily during the 6 months before and after the pandemic, respectively, while (14% versus 16%) were taking vitamin D supplements weekly during the 6 months before and after the pandemic Conclusion: The interest of taking multivitamin by Saudi population, such as vitamins C and D, zinc increased during and after the pandemic compared to that before it. There is no scientific evidence based on previous studies confirmed the role of dietary supplementation and multivitamins in preventing COVID-19 infection, therefore, effective education on the rationale use of vitamins during COVID-19 pandemic should be emphasized at local and/or national levels.

There is no standard as to treatment of anthracycline chemotherapy complications. The reduction of cytotoxic drugs toxicity without weakening of their antitumor action remains relevant. The extracellular matrix which key component is fibronectin is present in all tissues and it continuously undergoes controlled remodeling. So, the purpose of our work was to study the level of fibronectin in the experimental model of doxorubicin-induced cardiomyopathy and effects of this cytostatic and its co-administration with antioxidants of different nature.The level of fibronectin was measured by ELISA using monospecific antibodies against fibronectin (Sigma, USA), secondary anti-IgG labeled with horseradish peroxidase (Sigma, USA) and fibronectin standard (Sigma, USA). The study was conducted on Wistar male rats with weight of 210 ± 50 g which were divided into 4 groups by 8 animals in each group: 1 – control, rats receiving saline i/p; 2 – doxorubicin 1 mg/kg i/p once a week during 4 weeks; 3 – doxorubicin by the same scheme plus 1% 2-oxoglutarate in drinking water during 4 weeks;4 – doxorubicin by the same scheme and korvitin injection 30 min before doxorubicin application once a week during 4 weeks. Obtained data indicate the effect of doxorubicin to decrease in index mass heart in 38% of animals compared to control animals; decrease in total protein concentration by 8% (Р < 0,05) and increase of the level of fibronectin by 67% (P < 0,001) in blood plasma of rats and decrease in the level of fibronectin in the heart extract by 19% (Р < 0,05) under development of doxorubicin-induced cardiotoxicity. Increased fibronectin concentration in blood plasma had strong correlation with decreased total protein concentration in blood (r=0,80) and heart extract (r=0,59) in rats with doxorubicin-induced cardiomiophaty indicating the sensitive reaction of fibronectin to development of metabolic disorders under doxorubicin influence.

Abstract We evaluated a rate colorimetric method (Beckman) for measuring total protein in cerebrospinal fluid. The automated instrument we used was Beckman's ASTRA TM. A 100-microL sample of spinal fluid is introduced into the biuret reagent in the reaction cell and the increase in absorbance at 545 nm is monitored for 20.5 s. Solid-state circuits determine the rate of alkaline biuret-protein chelate formation, which is directly proportional to the total protein concentration in the sample. The linear range of measurement is 120 to 7500 mg/L. Day-to-day precision (CV) over the range of 150 to 1200 mg/L ranged from 15.2 to 2.3%. The method was unaffected by radical alteration of the albumin/globulin ratio, but there is a positive interference in the presence of hemoglobin, a suppression in the presence of bilirubin, and no effect by xanthochromia. The method is precise, accurate, rapid, and convenient. The method was compared with the trichloroacetic acid method as performed on the Du Pont aca III, giving a correlation coefficient (r2) of 0.9693. The method is precise, accurate, rapid, and convenient.
