Status of the cancer serum donor is recognized as presence of the laevorotatory optical active molecules of (-)p density in serum while status of the recovered donor is recognized as quantitative domination of the dextrorotatory (+)p molecules in serum. These molecular information carriers (-)p and (+)p are recorded by the magneto-optical circular birefringence MOCB effect in B2 magnetic field. The laevo/dextrorotatory carriers are enantiomers in the case of (-)p = (+)p relations fulfilled for any individual cancer and the same recovered patient. The positive predictive value PPV of MOCB results is 100%.展开更多

Using major news outlets, prominent magazines covering food and science issues, and advocacy websites concerning meat consumption, the paper characterizes the overall emphases of the coverage, the tenor of the coverage, and compares the media portrayal of the important issues to the demographic and psychological realities of the actual consumer market into which cultured meat will compete. In particular, the paper argues that Western media gives a distorted picture of what obstacles are in the path of cultured meat acceptance, especially by overemphasizing and overrepresenting the importance of the reception of cultured meat among vegetarians. Promoters of cultured meat should recognize the skewed impression that this media coverage provides and pay attention to the demographic data that suggests strict vegetarians are a demographically negligible group. Resources for promoting cultured meat should focus on the empirical demographics of the consumer market and the empirical psychology of mainstream consumers.展开更多

Currently the processes for the preparation of these compounds are carried out individually and in manual form, in box of gloves, presenting radiological risks. To avoid these risks, this work, shows equipment that is inside a warm cell with the finality of minimizing the radiological risks. Also, this semi-automated equipment has the purpose of to reduce the radiation exposure of personnel involved in the process of marking molecules. The routine industrial production with this equipment starts with the preparation of 9 marked doses of sodium iodohippurate of 2.73 mCi of iodine-131, each of the vials with saline solution of 4.5 mL and the product that containing the marked molecules of 0.5 mL with a percentage of marked of 95.6%. The innovation of this work consists in presenting a new design of equipment, for marked molecules, formed by electrical, mechanical, vacuum systems, and air extraction system.展开更多

This study aims to evaluate the clinical effectiveness and safety of suction tubes with markings in mechanically ventilated pediatric patients. Materials and Methods: A randomized assignment was carried out on a cohort of 52 pediatric patients who underwent mechanical ventilation in the Pediatric Intensive Care Unit at the Third Affiliated Hospital of Sun Yat-sen University, covering the period from January 2022 to December 2022. These patients were divided into two groups: an improved group (n = 26) utilizing marked suction tubes, and a regular group (n = 26) employing conventional suction tubes. The objective of our study was to evaluate the clinical effectiveness of marked suction tubes. Results: The effects of the improved group on the vital signs of children undergoing mechanical ventilation were small and statistically significant compared with the regular group (p < 0.05). Additionally, the improved group exhibited a reduced frequency of sputum suction, shorter mechanical ventilation duration, and fewer days of hospitalization in the PICU compared to the regular group during the ventilation period. Notably, the difference in the duration of PICU hospitalization was statistically significant (p < 0.05). Moreover, the incidence of adverse reactions in the improved group was notably lower, with statistically significant differences observed in airway mucous membrane damage and irritating cough when compared to the regular group (p < 0.05). Conclusion: The utilization of marked suction tubes provides clinical nurses with clear guidance for performing suctioning with ease, efficiency and safety. Consequently, advocating for the widespread implementation of marked suction tubes in clinical practice is a commendable pursuit.展开更多

During tests using the CFD （computational fluid dynamics） software different geometry of nozzle cups were compared by such parameters as pressure, velocity and direction of flow. Goal of digital experiments was to find sprayer nozzle geometry that can keep stream of paint in diameter of 10 mm on 10-20 mm distance. Main problem is to avoid low-pressure regions around the stream. The optimal geometry of nozzle cup is designed to get adjusted code dimensions on given distance展开更多
