Effect of Some Preservative Solutions on Some Morphometric Features of Planiliza abu (Heckel, 1843)

The present study attempts to find out the effect of some fish preservatives in the laboratory, such as alcohol and dilute formalin, on some biological characteristics related to the body measurements of those fish preserved in these materials. The fish used in this study were the local Planiliza abu. The processes of expansion and contraction of the bodies of fish preserved in diluted formalin solution at a concentration of 10% and diluted ethyl alcohol solution at a concentration of 70%. As that the standard length of the specimens of this study, which are separately preserved in formalin 10% and alcohol 70%, in a completely isolated are fluctuating in change. Constant shrinkage in head length in both diluted formalin and alcohol. Most fish bodies preserved in formalin at a concentration of 10% gain significant weight gain, in contrast to alcohol preservation.

A Pilot Study of the Influence of Natrum muriaticum at 6CH and 30CH Potency in a Standardized Culture of Phaseolus vulgaris

The use of highly diluted and dynamized solutions is widespread. Its use extends to all living beings, including vegetables, acting effectively in primary and secondary metabolism. The aim of the present pilot study was to confirm the action of Natrum muriaticum at 6 CH and 30 CH dilutions in comparison to the action of a 5.0% NaCl solution, when administered separately in population of Phaseolus vulgaris (common bean). An evaluation was performed by determining the Relative Growth Rate (RGR) of bean population treated for six weeks and subdivided into 4 groups (with 5 vases each): P1, the control group, which was treated with a 30% alcohol solution only; P2, treated with an aqueous 5.0% NaCl solution; P3, treated with Natrum muriaticun at 6 CH dilution; P4, treated with Natrum muriaticum at 30 CH dilution. The results obtained showed that an increase in soil salinity caused inhibition of the development of bean population (P2). In addition, the use of the Natrum muriaticum dilution promoted a significant increase in vegetable growth, chiefly related to the 6 CH (P3), causing a significant increase in the RGR of the bean population. The use of this high dilutions provided evidence that method is efficient in vegetables.

Corn (Zea mays) as a Nutrient Source and Diet: A Review

Maize is also known as corn; it is a cereal. It is a member of Poaceae family which is a grass family. Maize originated 55 to 70 million year ago in central America. By seeing phylogenetic tree of grass species related to maize, it can be conclude that there is no direct ancestor of maize. The closest ancestor of maize are teosintes. Maize contains many phytochemical-like phystosterols, carotenoids and many other phenolic compounds. Maize also helps while reliving anti-HIV activity; this takes place due to the presence of Galanthus Nivalis Agglutinin (GNA) lectin. Maize is the great source of essential fatty assets. The maize cob and the root leaves of it are used to treat problem related to bladder, Nausea, vomiting. The endosperm of maize contains an alcohol solution prolamine called Zein, Which has a great role in pharmaceutical industry. Maize also contains resistant starch which reduces cancer-cecal, atherosclerosis and obesity related issues.

Mechanical properties of native and decellularized aortic wall after long-term storage in biocide solutions

Objective: to determine the optimal method for long-term wet storage of donor material (50 days after collection), with maximum ability to preserve the original mechanical characteristics.Materials and methods. Porcine aortic wall fragments were used as objects of study. Half of the original material underwent detergent-based decellularization. The entire material (native and processed) was placed for 50 days in biocidal solutions: complex alcohol solution; ethanol and glycerol mixture; antibiotics mixture. Then the tests for mechanical strength of native and decellularized samples were carried out by the method of uniaxial longitudinal and circumferential stress.Results. Storage of native material in all media resulted in a significant increase in tensile strength. In the «complex alcohol solution», «ethanol and glycerol mixture», and «antibiotic mixture» group, tensile strength increased by 1.38-, 1.72- and 1.62-fold compared to the native control in circumferential tension. Also, in the «complex alcohol solution» group, the decellularized material was 1.57-fold stronger than the native in circumferential tension. In the «antibiotic mixture» group, the decellularized material was 1.33-fold less strong than the native in longitudinal tension. According to elongation to rupture data, significantly greater plasticity was noted in the «ethanol-glycerol» storage group for the decellularized aortic wall compared to the control group (1.5-fold). Young’s modulus did not reliably differ from those of control in all experimental groups regardless of the stress direction. Notably, decellularized specimens clearly tended to be stiffer under circumferential stress.Conclusion. Detergent-based decellularization of the porcine aortic wall and subsequent storage of these samples in our chosen experimental solutions for 50 days does not significantly affect the elastic properties of the material. Our proposed treatment methods partially increase the stiffness of the material after storage in alcohol-containing solutions.

Ubiquinol ameliorates endothelial dysfunction and increases expression of miRNA-34a in a rat model of pulmonary hypertension

Introduction: In this research, we evaluate the effect of intravenously administrated solubilized ubiquinol on 4-week monocrotalin-induced pulmonary hypertension (PH) in rats. Materials and methods: To reproduce the model, some male Wistar rats were subcutaneously injected with alcohol solution of monocrotaline 60 mg/kg and the rest – with alcohol solution (Control). Those with monocrotaline (MCT) were divided into 3 groups. They underwent intravenous administration of 1% ubiquinol solution 30 mg/kg (MCT-Ubiquinol), the vehicle (MCT-Vehicle) and saline (MCT-saline) three times on days 7, 14 and 21, depending on the group. The hemodynamic parameters were measured in anesthetized rats on day 29. Right ventricle hypertrophy, pulmonary arteries reactivity and expression of miRNA-21 and miRNA-34a were estimated after euthanasia. Results and discussion: All MCT-groups demonstrated an increase in right ventricle systolic pressure and hypertrophy in comparison with the control group. An increase in lung weight was shown in MCT-Vehicle and MCT-Saline; however, the MCT-Ubiquinol indicators did not differ from those of the Control. There was an increased vasodilatation response to acetylcholine at concentrations of 1*10-6M and 1*10-5M in MCT-Ubiquinol in contrast to the other two MCT-groups. A significantly lower level of expression of miRNA-34a was observed in MCT-Ubiquinol. Conclusion: Our findings suggest that a triple ubiquinol injection influences pulmonary changes and endothelium-depended vasodilatation, which contributes to pulmonary vascular tone and reactivity. A decrease in miRNA-34a expression in MCT-Ubiquinol group demonstrates the ubiquinol anti-inflammatory properties.
