Human Eosinophil Cell Manipulation by Optical Tweezers

Open Journal of Biophysics 2024年第3期14卷 330-338页

In this work, lateral deformation of human eosinophil cell during the lateral indentation by an optically trapped microbead of diameter 4.5 µm is studied. The images were captured using a CCD camera and the Boltzmann statistics method was used for force calibration. Using the Hertz model, we calculated and compared the elastic moduli resulting from the lateral force, showing that the differences are important and the force should be considered. Besides the lateral component, the setup also allows us to examine the lateral cell-bead interaction. The mean values of the properties obtained, in particular the elastic stiffness and the shear stiffness, were Eh = (37.76 ± 2.85) µN/m and Gh = (12.57 ± 0.32) µN/m. These results show that the lateral indentation can therefore be used as a routine method for cell study, because it enabled us to manipulate the cell without contact with the laser.

Background: Infertility affected 10% to 25% of couples globally, and about half of the infertility cases were reported in sub-Saharan Africa. Infertility poses significant social, cultural, and health challenges, particularly for women who often face stigmatization. However, comprehensive and nationally representative data, including prevalence, temporal trends, and risk factors, are lacking, prompting a study in Burkina Faso to address the need for informed policies and programs in infertility care and management. Objectives: This study aims to better understand the spatiotemporal trend of infertility prevalence in Burkina Faso. Methodology: This is a retrospective population-based study of women infertility from healthcare facilities in Burkina Faso, during January 2011 to December 2020. We calculated the prevalence rates of infertility and two disparity measures, and examined the spatiotemporal trend of infertility. Results: Over the 10-year period (2011 to 2020), 143,421 infertility cases were recorded in Burkina Faso healthcare facilities, resulting of a mean prevalence rate of 3.61‰ among childbearing age women and 17.87‰ among women who consulted healthcare facilities for reproductive issues (except contraception). The findings revealed a significant increase of infertility, with the prevalence rate varied from 2.75‰ in 2011 to 4.62‰ in 2020 among childbearing age women and from 13.38‰ in 2011 to 26.28‰ in 2020 among women who consulted healthcare facilities for reproductive issues, corresponding to an estimate annual percentage change of 8.31% and 9.80% respectively. There were significant temporal and geographic variations in the prevalence of infertility. While relative geographic disparity decreased, absolute geographic disparity showed an increasing trend over time. Conclusion: The study highlights an increasing trend of infertility prevalence and significant geographic variation in Burkina Faso, underscoring the urgent necessity for etiologic research o

On October 13,2020,on the fairway connecting the Polish Baltic ports ofSwinoujscie and Szczecin,an underwater hazardous object of historical origin in the form of the British deep penetration bomb Tallboy dropped during the bombing of the German cruiser"lützow"in April 1945 was neutralized *** is believed to be the first underwater action concerning this type of bomb,which has previously been neutralized on land in Europe(Germany,one confirmed case).The preparation of the operation,on an unprecedented scale at national,European and global level,took one year and included a series of projects related to clearing the space around the bomb from other identified UXO objects,international consultations,historical analyses,determination of the risk to residents and critical infrastructure in the event of an explosion of the bomb containing approximately 2400 kg of the TORPEX explosive(with an increased force equivalent to almost 3600 kg of TNT).The object was neutralized on spot at the depth of 12 m,near a ferry crossing,by specialists from the 41st Navy EOD Team from the 12th MCM Squadron(8th Coastal Defence Flotilla),using the low Order Deflagration technique(underwater deflagration method).In the case discussed,there was an accumulation of unfavourable conditions which practically excluded the use of blow-in-situ explosive methods(BIP),as well as the extraction of the object and its transport to a military *** a partial deflagration of the explosive,the explosive was detonated(DDT).Estimates indicate that the deflagration level reached between 55 and 60%,which significantly reduced the strength and effects of the underwater explosion.
