Summary of Research on Magnetic Fluid and Its Inclination Sensor

Magnetic fluid is a multifunctional new fluid material. Because of its combination of magnetism and fluidity, it has an irreplaceable role in many occasions.The application of magnetic fluid in the sensor field is not yet mature, but with the continuous attempts of researchers, the huge potential of magnetic fluid in this field has been explored.This paper mainly introduces the application of magnetic fluid in the field of sensor, and briefly introduces the characteristics and manufacturing method of magnetic fluid.The principle of the magnetic fluid inclination sensor is introduced emphatically, and the magnetic fluid inclination sensor is classified according to the different restriction methods of the magnetic fluid.Pointed out the gap between the research directions of magnetic fluid inclination sensors at home and abroad, as well as the problems existing in research and development, and prospects for future innovation in this field.

Status of Antimicrobial Stewardship Implementation in Some Egyptian Hospitals, a Cross-sectional Study

Background: Antimicrobial stewardship (ASP) aims to stopping or slowing emergence of antimicrobial resistant strains. After initiation of National action plan on antimicrobial resistance (AMR) in Egypt, there were several initiatives by hospitals to implement ASP but no formal assessment was performed.Objective & setting: This study attempts to assess the extent of ASP application in different Egyptian hospitals; stewardship knowledge & implementation in selected hospitals. Method: A cross-sectional study was conducted to assess stewardship knowledge & implementation in selected hospitals in Egypt. Main outcome measure: Core elements of the survey included Hospital Description, ASP committee, ASP Activities (including training, restriction methods and outcome measurement), reporting antibiotic use, antibiogram, information technology (IT) support, ASP restriction methods and ASP Future ApplicationResults: The study included many aspects regarding hospital description; all types of hospitals were involved. Most of hospitals (61.8%) implemented an ASP program while 38.2% did not; 71.4 % of the later are planning for future Antimicrobial stewardship application. 22 hospitals (48.5%) reported having facility-specific antibiogram on regular basis. 13 hospitals (37.1%) reported receiving antimicrobial reports on regular basis. 15 hospitals (42.9%) reported having one or more computer programs already in use. The monitoring activities included resistance patterns, infection rates, length of stay, mortality rate & reported adverse drug reactions. Only 20% of the hospitals included in this study reported having an ASP training program. Conclusion: Egyptian hospitals have a fairly good implementation, improvements need to include IT support programs, healthcare members cooperation, monitoring outcomes & infectious disease (ID) consultations.

Comprehensive Cross-Efficiency Methods with Common Weight Restrictions in Data Envelopment Analysis

Considering both self-evaluation and peer evaluation, the traditional data envelopment analysis (DEA) cross-efficiency method has been widely used to evaluate efficiency scores. However, it has several defects such as excessive weight flexibility, unstable evaluation, and aggregation irrationality. This paper proposes a novel comprehensive DEA cross-efficiency method where two novel weight restriction methods are used to enhance the stability and feasibility of evaluation. Then, final efficiency scores were calculated through the geometric mean aggregation method. Finally, an empirical example is used to demonstrate that the proposed methods are more reasonable and scientific.

A Novel Micronutrient Blend Mimics Calorie Restriction Transcriptomics in Multiple Tissues of Mice and Increases Lifespan and Mobility in C. elegans

Background: We previously described a novel micronutrient blend that behaves like a putative calorie restriction mimetic. The aim of this paper was to analyze the beneficial effects of our micronutrient blend in mice and C. elegans, and compare them with calorie restriction. Methods: Whole transcriptomic analysis was performed in the brain cortex, skeletal muscle and heart in three groups of mice: old controls (30 months), old + calorie restriction and old + novel micronutrient blend. Longevity and vitality were tested in C. elegans. Results: The micronutrient blend elicited transcriptomic changes in a manner similar to those in the calorie-restricted group and different from those in the control group. Subgroup analysis revealed that nuclear hormone receptor, proteasome complex and angiotensinogen genes, all of which are known to be directly related to aging, were the most affected. Furthermore, a functional analysis in C. elegans was used. We found that feeding C. elegans the micronutrient blend increased longevity as well as vitality. Conclusions: We describe a micronutrient supplement that causes similar changes (transcriptomic and promoting longevity and vitality) as a calorie restriction in mice and C. elegans, respectively, but further studies are required to confirm these effects in humans.
