e15569 Background: To investigate the residence time of 99mTc-labeled cytarabine in mouse tumors under ECT imaging. Methods: The subcutaneous solid tumor model of mice was established by injection of melanoma cell suspension into the left forelimb of C57 mice. The tumor-bearing mice were divided into treatment group and control group when the longest diameter of the tumor was 5-8 mm. Group 3 only. The mice in the control group were given intratumoral injection of 0.1 ml of 99mTc-labeled cytarabine solution, and the mice in the treatment group were given intratumoral injection 0.1 ml 99mTc labeled cytarabine combined with hydrogen peroxide solution at 0.25 h, 0.5 h, 1 h. After 2 hours and 19 hours of administration, the radioactivity intensity values were observed by SPECT Apx-409 ECT phenomenon equipment. Results: The T/W values of ECT imaging in 3 mice in the treatment group were higher than those in the control group at 0.25 h, 0.5 h, 1 h, 2 h and 19 h. The T/W values of ECT imaging decreased in the treatment group at different time points. The amplitude was lower, and the T/W values in each period were higher than those in the control group. Conclusions: The sustained release agent hydrogen peroxide can significantly increase the residence time of 99mTc-labeled cytarabine in the tumor. It is speculated that hydrogen peroxide has a positive effect on prolonging the drug action time of cytarabine and improving the effect of killing tumor cells. It showed that H2O2 can hold the Ara-C for a long time in tumor.

Every 30 seconds somewhere in the world there occurs a lower limb amputation in a patient with foot phlegmon. Antibacterial agents are the basis of systemic pharmacotherapy of surgical infections. However, such treatment is rather difficult as it is associated with the loss of antibiotic sensitivity. The purpose of the study is to determine the antibacterial effects of innovative hydrogen peroxide and nanosilver composition combined with chitosan lymphostimulation in foot phlegmon treatment for limb salvage. Materials and Methods. The work is based on the analysis of 46 patients’ treatment outcomes. All the patients suffered from purulent-necrotic foot phlegmons and were treated at the Scientific Center for Reconstructive Surgery, the Ministry of Health of the Kyrgyz Republic and Chuy Regional Combined Hospital. The patients were divided into 2 groups: control group (n=22) – conventional treatments, and active treatment group (n=24) – additional administration of bactericidal-lymphotropic cocktail. The groups were comparable in sex, age, and soft tissue involvement. Results. In patients of active treatment group wound cleansing from wound detritus was observed in 5 days, while in patients undergoing conventional treatment it was detected only in 9 days. In the active treatment group, the granulation time was 1.8 times faster, and the normalization of the leukocyte intoxication index was 2.5 times earlier. The dynamics of the level of medium-weight molecules indicated that lymphostimulation accelerated the interstitium detoxification process in the affected limb by 3 times. Conclusion. The proposed modified method for foot phlegmon treatment with bactericidal-lymphostimulating technologies accelerates tissue regeneration and contributes to limb salvage. Keywords: foot phlegmon, hydrogen peroxide, nanosilver, chitosan. Каждые 30 с в мире пациенту с флегмоной стопы производится ампутация нижней конечности.

Specimen support and astigmatism correction in Electron Microscopy are at least two areas in which lacey polymer films find extensive applications. Although their preparation has been studied for a very long time, present techniques still suffer from incomplete release of the film from its substrate and presence of a large number of pseudo holes in the film. Our method ensures complete removal of the entire lacey film from the substrate and fewer pseudo holes by pre-treating the substrate with Gum Arabic, which acts as a film release agent.The method is based on the classical condensation technique for preparing lacey films which is essentially deposition of minute water or ice droplets on the substrate and laying the polymer film over it, so that micro holes are formed corresponding to the droplets. A microscope glass slide (the substrate) is immersed in 2.0% (w/v) aq. CTAB (cetyl trimethyl ammonium bromide)-0.22% (w/v) aq.

A test was done to see if reading a newspaper which consistently overrepresents foreigners as criminals strengthens the automatic association between foreign country and criminal in memory (i.e., implicit cultivation). Further, an investigation was done to find out if reading articles from the same newspaper produces a short-term effect on the same measure and if (1) emotionalization of the newspaper texts, (2) emotional reactions of the reader (indicated by arousal), and (3) attributed text credibility moderate the short-term treatment effect. Eighty-five participants were assigned to one of three experimental conditions. Participants in the control group received short factual crime texts, where the nationality of the offender was not mentioned. Participants in the factual treatment group received the same texts, but the foreign nationality was mentioned. Participants in the emotionalized treatment group received emotionalized articles (i.e., texts which are high in vividness and frequency) covering the same crimes, with the foreign nationality mentioned. Supporting empirical evidence for implicit cultivation and a short-term effect was found. However, only emotionalized articles produced a short-term effect on the strength of the automatic association, indicating that newspaper texts must have a minimum of stimulus intensity to overcome an effect threshold. There were no moderating effects of arousal or credibility pertaining to the impact on the implicit measure. However, credibility moderated the short-term effect on a first-order judgment (i.e., estimated frequency of foreigners of all criminals). This indicates that a newspaper’s effect on the strength of automatic associations is relatively independent from processes of propositional reasoning.
