Nickel Influences Urease Activity and Calcium Distribution in Tomato Fruits

Objective: To study the effect of storage temperatures and dehydration conditions (solar and convective drying; SD, CD), on the quality, physicochemical parameters and antioxidant properties of tomato fruits. Methodology: The physicochemical characteristics pH, titratable acidity, soluble solids (°Bx) and color parameters (L*, a* and b*), were evaluated. The lycopene, carotenoids and antioxidant activity percentages retention of tomatoes fruits stored at 7 and 22 ° C for 5 days and subjected to SD (Temperature (T) of 67 °C and luminescence of 685 lum/sqf) and CD (T 70 °C, flow rates 0.5, 1.0 and 1.5 m/s), were analyzed. Results: The fruits reached humidities of 17 and 15% for SD and CD. The parameters pH, °Bx, L*, a*, b* were highest with 22°C and CD (1.5 m/s). The value of the carotenoids was higher in fruits stored at 7 ° C and subjected to CD (1.0 and 1.5 m/s) and SD with values of 83.85, 85.98 and 99.43%, respectively. The CD (0.5 m/s) and SD improved lycopene (94.37 and 95.14%) and the antioxidant activity with values of 73.06 and 97.21%. Implications: The application of solar dehydration depends on luminescence condition; however, it is inexpensive and environmentally friendly alternative. Conclusions: The results derived in a viable alternative for the conservation and commercialization of tomato fruits in rural communities

Positive Results

(HP) infection was performed using invasive and non-invasive methods. The study group consisted of 95 patients with dyspepsia. HP infection was detected in 47 patients (49.4 %). The expediency of using a set of diagnostic methods for detecting HP (PCR, immunochromatographic, bacteriological and method for determining urease activity) is proved. Most often (100 %) in patients HP infection was detected in biopsies using the PCR method. Somewhat less frequently it was detected when examining biopsies with an invasive biochemical method (AMA RUT Reader) (82 %) and fecal immunochromatographic method (83 %). Despite the fact that helicobacteriosis was detected bacteriologically in a small number of patients (24 %), this method is of particular value, since it allows you to assess the sensitivity to antimicrobial drugs and probiotics, and does not give false positive results.

Colour Development

The study was conducted to assess the effect of different waxing materials on the quality attributes of tomato fruits. A 2 x8 factorial experiment layout in complete randomized design with 16 treatment combinations and 3 replication was adopted.The materials that were used for the experiment are two (2) varieties of tomatoes (Pectomech and Power Rano) and seven(7) waxing material (shea butter, cassava starch, beeswax, and a combination of shea butter + cassava starch, shea butter + beeswax, cassava starch + beeswax, shea butter + cassava starch + beeswax) and a control. Results from the experiment indicated that all waxing treatments delayed the development of weight loss, firmness, pH, total soluble solids, and total titrable acidity. The results also suggested that edible wax coatings delayed the ripening process and colour development of tomato fruits during the storage period and extended the shelf life. However Beewax treatment and its combinations performed better than the other treatments. It was therefore recommended that locally produced wax such as Beewax, Shea butter, Cassava Starch treatments and their combinations could be a good technology for preserving the quality and extending the shelf life of fresh tomato fruit as well as maintaining the physical and chemical properties.

Periodontal Tissues

Diseases of periodontal tissues occupy one of the leading positions among modern dental problems, namely the multifactorial nature of these diseases. In modern dental science, the issue of the development of periodontal pathology against the background of somatic pathology and risk factors remains relevant. Pathology of periodontal tissues in 68–90 % of cases is accompanied by chronic diseases of the gastrointestinal tract. Today, there is no doubt that Helicobacter pylori infection can be present in the biotopes of the oral cavity and can affect the course of periodontal pathology. As you know, smoking is one of the important risk factors for the development of inflammatory-dystrophic diseases of periodontal tissues, which can aggravate the course of the latter. The purpose of the work is to determine the prevalence of oral Helicobacter pylori infection in tobacco-dependent patients with chronic generalized periodontitis on the background of chronic hyperacid gastritis during treatment. Patients who received the proposed therapeutic and prophylactic complex (ultraphonophoresis procedures with the created gel «Apisan», and probiotic drug BioGaia ProDentis and angioprotective drug of natural origin — Detralex) showed a gradual decrease in the level of total urease activity and, as a consequence, a decrease the prevalence of Helicobacter pylori infection in the oral cavity according to the results of a urease rapid test with material from the oral cavity, both in the presence of a risk factor — smoking, and in its absence. The use of the proposed therapeutic and prophylactic complex proved to be effective in reducing the prevalence of oral Helicobacter pylori infection in smoking patients and patients who do not smoke, with chronic generalized periodontitis against the background of chronic hyperacidal gastritis associated with Helicobacter pylori.
