Storage Technologies

Cherry fruits have a short shelf life due to the period of their storage. Therefore, to extend it, a search for new storage technologies is underway. The purpose of the research carried out during 2016-2019 at the experimental pomology station named after L.P. Simirenko IS NAAN, was the determination of the organoleptic and physical characteristics of fresh cherry fruits before and after storage when processed with polysaccharide compositions. Studies have shown that the weight of cherry varieties Zhadana, Chance, Optimist and In Memoriam Artemenko are large, their weight ranges from 5.2 to 4.8 g. The color of cherry fruits, experimental varieties, determined by the light transmittance did not indicate a significant difference within the variety. The sugar-acid index of cherry fruits prevailed in cherry fruits of Elegant and Alpha varieties, taking values above 5. Cherry fruits had a good organoleptic evaluation. Among all the experimental varieties, the fruits of the Elegant cherry variety were distinguished by their excellent tasting evaluation, appearance and gloss. According to the studied physical and organoleptic parameters and the cluster analysis, the Griot Podbelsky variety (control) was more universal. According to the group of indicators, the fruits of cherry varieties: Alpha, Optimist and Zhadana differed from Elegant and Chance. The smallest changes, compared to the control, in the fruits of cherries varieties Alpha and Optimist. After storage of cherry fruits treated with chitosan with salicylic acid compared to untreated fruits, the taste of the fruit did not deteriorate. Fruits treated with a solution of salicylic acid with chitosan or sodium alginate had an excellent tasting score. The prospect of further research is to establish the effect of polysaccharide compositions based on chitosan and sodium alginate and organoleptic characteristics of cherries of different varieties after storage.

The article reflects the assessment of the quality of sour cream at home, and considers methods for determining the quality of sour cream. Organoleptic evaluation was performed for compliance with the requirements of GOST 52092-2003 " Smetana. Technical conditions " in terms of appearance, consistency, color, taste and smell. The consistency of sour cream is determined during its mixing, while evaluating the presence of a glossy appearance of sour cream. Sour cream is considered thick if it slowly drains from the whorl. The smell is determined immediately after mixing. Then we evaluate the taste. When evaluating the quality of the samples under study, it was found that the organoleptic characteristics of the samples fully comply with the requirements of the regulatory document. Analyzing the results of the experiment, we can conclude that in the first experiment, the sour cream purchased on the market was completely dissolved, and the sour cream from the store after dissolution showed small grains. And in the second experiment, the results showed that the color did not change in the sample # 2, but under # 1 it turned blue. The basis of this experiment is a qualitative chemical reaction to starch, which is used as a thickener.

Purpose: To quantitatively assess retinal neovascularizations (RNVs) in proliferative diabetic retinopathy (PDR) before and after photocoagulative laser treatment (PLT) using Optical Coherence Tomography Angiography (OCT-A). Methods: Consecutive patients with PDR were examined with fluorescein angiography (FA) and OCT-A before and after PLT. Baseline and after-treatment FA images were quantitatively analyzed to assess both the RNVs area and leakage area. On OCT-A RNVs area, vascular perfusion density (VPD), vessel length density (VLD) and fractal dimension were computed. VPD of the full-retina OCT-A underneath the RNV was determined to evaluate potential laser-induced changes in vascular perfusion. Results: Fifteen eyes of 13 patients with PDR were enrolled. The mean area of the RNVs was 0.47 ± 0.50 mm2 in the baseline OCT-A and 0.32 ± 0.40 mm2 in the post-treatment assessment ( p = 0.0002). The mean RNV VPD of RNV was 2% ± 4% in pre-treatment and 1% ± 1% for the post-treatment ( p = 0.0001). The mean VLD of RNV was 7.26 ± 1.53 at baseline and 6.64 ± 1.65 in the post treatment ( p = 0.0002). A significant difference in terms of mean RNVs area and VPD reduction between eyes that needed additional treatment and those that did not (~40% vs ~20%; p < 0.05), was observed. Mean VPD of full-retinal thickness OCT-angiogram was 55% ± 10% for the pre-treatment and 53% ± 8% for the post treatment scan ( p = 0.02). Conclusion: The quantitative OCT-A assessment of laser-induced changes of RNVs can be a useful non-invasive approach for determining treatment efficacy. A reduction of RNVs area or VPD ⩾ 40% might reveal those eyes that won’t require additional treatment. Retinal perfusion impairment seemed to progress independently from the treatment.

The objective of this study is to explore the effects of acupuncture and auricular acupressure in relieving menopausal hot flashes of bilaterally ovariectomized Chinese women. Between May 2006 and March 2008, 46 bilaterally ovariectomized Chinese women were randomized into an acupuncture and auricular acupressure group (n= 21) and a hormone replacement therapy (HRT) group (Tibolone,n= 25). Each patient was given a standard daily log and was required to record the frequency and severity of hot flashes and side effects of the treatment felt daily, from 1 week before the treatment started to the fourth week after the treatment ended. The serum levels of follicle stimulating hormone (FSH), LH and E2were detected before and after the treatment. After the treatment and the follow-up, both the severity and frequency of hot flashes in the two groups were relieved significantly when compared with pre-treatment (P<  .05). There was no significant difference in the severity of hot flashes between them after treatment (P>  .05), while after the follow-up, the severity of hot flashes in the HRT group was alleviated more. After the treatment and the follow-up, the frequency of menopausal hot flashes in the HRT group was reduced more (P<  .05). After treatment, the levels of FSH decreased significantly and the levels of E2increased significantly in both groups (P<  .05), and they changed more in the HRT group (P<  .05). Acupuncture and auricular acupressure can be used as alternative treatments to relieve menopausal hot flashes for those bilaterally ovariectomized women who are unable or unwilling to receive HRT.

The aim of this work was to develop a sensitive, simple and direct procedure for the determination of Cu, Cd, Cr, Pb, Mn and Al in the cooking wine by HR-CS GFAAS with a minimum sample pre-treatment. The analyses of the six metal elements were conducted using a high resolution continuum source atomic absorption spectrometer. The cooking wine as sample was just diluted in ultrapure water with 1.0% (v/v) HNO3and the analytical lines of the six metal elements were selected scientifically. The correlation coefficients better than 0.99 were obtained and the limits of detection were 0.86, 0.08, 0.28, 0.81, 0.61 and 1.54 μg/L for Cu, Cd, Cr, Pb, Mn and Al, respectively. Recoveries varied form 96.1% to 105.7%. The proposed method was applied to the determination of the six metal elements in the cooking wine and the results showed that the mass concentrations of Cu, Cd, Cr, Pb, Mn and Al were 2.10, 0.177, 7.98, 1.86, 22.3 and 217.2 μg/L, respectively. There was a good agreement between the proposed method and the microwave digestion-HR-CS GFAAS method, and F-test and t-test at 95% of confidence had no significant difference. Therefore, the proposed method was accurate and stable with a high practical value. It provided scientific basis for quality control in food industries.

ABSTRACT A method is described and evaluated for the determination of androstenedione (A) in peripheral venous plasma. The potential use of antisera to A-6-carboxymethyl thioether-bovine serum albumin and A-11α-succinyl-bovine serum albumin has been evaluated. The same plasma samples have been analysed before and after chromatography on a micro column of Sephadex LH-20. A dye, azobenzene is used to locate the fraction containing androstenedione. The results show that there is no significant difference in the values of apparent A using either antisera (overall mean 3.2 ng/ml plasma from men and 2.8 ng/ml from women). After chromatography these values are reduced by 62 and 42% respectively to 1.2 and 1.6 ng/100 ml. A new method using a mixture of ammonium and calcium sulphates is described for the separation of steroid bound to antibody. The precipitate is then resuspended and the amount of radioactivity determined, directly in the assay tube, by liquid scintillation counting. This process effects a 68 % reduction in the cost of the assay of each plasma sample.

ABSTRACT Aim The aim of this study was to determine the root canal area before and after the instrumentation 1 mm short of the apical foramen by clinical and cone beam computed tomography (CBCT) methods, and to evaluate the cleanliness of the apical region in mesiodistal flattened teeth by using optical microscopy. Materials and methods Forty-two human single-canal mandibular incisors were instrumented using the Free Tip Preparation technique up to three, four or five instruments from the initial. Cone beam computed tomography scans were acquired of the samples before and after root canal preparation (RCP). Irrigation was performed by conventional or hydrodynamic means, using 2.5% sodium hypochlorite. The samples were prepared for observation under an optical microscope. Images were digitally obtained, analyzed and the results were submitted to statistical analysis (two-way ANOVA complemented by Bonferroni's post-test). Results There was no significant difference between the studied anatomical areas with both CBCT and clinical methods. There were no differences between irrigation methods. It was verified differences between instrumentation techniques. Instrumentation with four instruments from the initial instrument determined a significant increase in the contact area when compared to preparation with three instruments, but RCP with 5 instruments did not result in a better cleanliness. Conclusion The analysis with CBCT was not capable to determine the precise shape of surgical apical area comparing to the clinical method. Clinical significance Both the conventional and hydrodynamic irrigation techniques were not able to promote root canals debris-free. The instruments action in root canal walls was proportional to the number of instruments used from the initial apical instrument.

Cherry fruits have a short harvesting season and a limited shelf life of only a few days. Therefore, it is necessary to develop modern storage technologies that would allow to extend their consumption period. The purpose of the study was to determine the storage efficiency of cherry fruits, pre-treated with polysaccharide compositions, by the Harrington method. For research, the fruits of Alpha and Pamyat Artemenka cherries varieties, sprayed with a solution of salicylic acid; solution of chitosan with salicylic acid, dried, removed from the trees at the consumer stage of maturity, each variety and type of processing, put in boxes №5 for storage at a temperature of 1±0.5 °C and relative humidity of 95±1 %. Physicochemical and organoleptic parameters were determined in the fruits during storage. The generalized Harrington function was used to summarize the results of the research. According to the generalized response, cherry fruits of the Alpha and Pamyat Artemenka varieties are better preserved after pre-treatment with a solution of salicylic acid with chitosan (D = 0.95 and 0.97). They were slightly inferior to cherry fruits treated with a solution of salicylic acid with a generalized response rate of 0.86 and 0.77. Cherry fruits pre-treated with a solution of salicylic acid with chitosan were stored for up to 30 days whereas the untreated ones (control) were stored for only 15 days (D = 0.63 and 0.49). Since the indicators of the generalized response were higher in the fruits of Alpha cherries, compared with the Pamyat Artemenka, Alpha cherry fruits can be considered more suitable for storage. Thus, the use of the generalized Harrington desirability function made it possible to objectively assess the cherries for suitability for storage. Treatment with a solution of salicylic acid with chitosan was the best for processing cherry fruits before storage. Key words: cherry fruits, Harrington method, salicylic acid, chitosan, storage.

Survey Results

The dynamics of political communication have occurred through phenomena before and after the presidential election in Indonesia, both conducted by political elites, party supporters, and the public to win the presidential candidates and vice-presidential candidates he supports. This can be seen from the form of political communication in the campaign, political attitudes in addressing the vote acquisition, and post-election political communication. Political communication through campaigns using digital media especially social media such as Twitter, Whatsapp, Facebook, Instagram, and other media has given a very significant influence in gaining public support, but negative campaigns and black campaigns (hoax) cannot be avoided, even to the legal sphere. Political communication at the end of the voting is stated through a victory speech through political speeches based on different survey results, namely quick count and exit poll. The speech added to the polemic about the validity and honesty in the implementation of the General Election because of the very significant difference in votes in Indonesia. Political communication on the determination of the results of the real count resulted in an unelected presidential candidate bringing the case to the realm of law namely the Constitutional Court court to cancel the victory of the elected presidential candidate. Political communication after the determination of the results of the elected election is that the elected president reconciles the non-elected presidential candidates to eliminate friction in the community. Besides, the coalition party supporting the elected president lobbied both fellow supporters and the elected president to get a ministerial position in the cabinet and the parliament.

Detoxification Process

The detoxification process in medication overuse headache is the most difficult process for the patient. We aimed to investigate the effectiveness of the combination of low dose IV lidocaine and magnesium (100 mg lidocaine and 1.25 mg magnesium) in patients with medication overuse headache during the detoxification process. A total of 30 patients were included in the study; 15 received 24 hours of IV hydration, 15 received 1-hour lidocaine-magnesium infusion at the onset of pain in addition to the 24 hours of IV hydration. Headache severity (numeric rating scale, NRS), attack durations, onset of headache, monthly analgesic/triptan intakes, numbers of monthly headache days data were documented. We evaluated the severity of headache before and after daily treatment of two groups for one week. When both groups were compared, there was no significant difference in the pre-treatment NRS values, whe­reas, in the group receiving IV lidocaine-magnesium combination, there was a statistically significant decrease in the post-treatment NRS values in the first five days (p <0.05). An 1-hour combined infusion of lidocaine-magnesium may be considered as an alternative option for the patient to have a more quality detoxification process during the hospital stay, so that in parallel to the reduction in the use of multiple treatments (such as neuroleptics, benzodiazepines, antiemetics and opioids) and duration length of stay, the economic costs can also be reduced. The administration of combination will bring fewer side effects compared to their administration separately.
