Complete fusion of two selected ceils allows for the creation of novel hybrid cells with inherited genetic properties from both original cells. Alternatively, via fusion of a selected cell with a selected vesicle, chemicals or genes can be directly delivered into the cell of interest, to control cellular reactions or gene expression. Here, we demonstrate how to perform an optically controlled fusion of two selected cells or of one cell and one vesicle. Fusion is mediated by laser irradiating plasmonic gold nanoparticles optically trapped between two cells （or a vesicle and a cell） of interest. This hot-particle-mediated fusion causes total mixing of the two cytoplasms and the two cell membranes resulting in formation of a new hybrid cell with an intact cell membrane and enzymatic activity following fusion. Similarly, fusion between a vesicle and a cell results in delivery of the vesicle cargo to the cytoplasm, and after fusion, the cell shows signs of viability. The method is an implementation of targeted drug delivery at the single-cell level and has a great potential for cellular control and design.

Employing the linearized Vlasov-Maxwell equations, a generalized dispersion relation for the ordinary mode is derived by employing the Cairns distribution function. The instability of the mode and its threshold condition is investigated. It is found that the temperature anisotropy χ= TⅡ I⊥〉 1 required to excite the instability varies with density values whereas the growth rate is dependent on various parameters like non-thermMity A, equilibrium number density no and temperature anisotropy. It is found that with the increase in the values of any of the parameters A, no and X, the growth rate is enhanced and the k-domain is enlarged. The results are applicable for space plasma environments like solar wind.

Computational calculations using density functional theory(DFT) were performed for the first time using the full potential linearized augmented plane wave plus local orbital method(FP-LAPW + LO) to determine the structural, elastic, electronic and magnetic properties of europium-based cubic perovskites EuYO_(3)(Y=Cr, Mn, Fe). The exchange correlation potentials of GGA along with some analytical methods were adopted for the computation of structural and elastic properties. Moreover, the GGA + U formalism was also added for obtaining more precise electronic and magnetic properties, particularly to address the Eu-4f and Y-3d orientations in the spin-polarized double cell symmetry. The observed lattice parameters of these compounds are consistent with experiment. The observed bulk moduli predict that EuCrO_(3) is harder and less compressible than EuMnO_(3) and EuFeO_(3). The calculated tolerance factors of these compounds are within the cubic symmetry range. Our computed critical radius of EuCrO_(3) shows that EuCrO_(3) has a larger migration energy. Based on their elastic properties, these compounds are ductile in nature. We also computed the thermal properties of these compounds. The band structures and density of states show that these compounds are metallic in character. The lowest ground state energy and magnetic moments of these compounds expose their ferromagnetic nature. The metallic nature and strong ferromagnetism of these compounds make them promising applicants for application in spintronic.

AIM To investigate the quality of life(QOL) and its clinical and epidemiological correlates among people with type 2 *** This cross-sectional study was conducted in Tabriz, Northwest of Iran, including a total of 394 people with type 2 diabetes using convenient sampling method from November 2014 to March 2015. General information including demographic, socioeconomic status and lifestyle factors were collected by trained interviewers. Clinical information was retrieved from clinic's record and QOL was assessed using the 26-item WHOQOL-BRIFE questionnaire. Univariate and multivariate linear regression were performed to assess the related factors and QOL dimensions. RESULTS The mean of overall health related QOL was 52.11 ± 11.53 and the maximum and minimum dimensions wererespectively seen in psychological(60.38 ± 14.54) and social(38.32 ± 16.94) dimensions. The results of multiple linear regression showed a significant overall relationship between HRQOL and age(b =-1.48%, 95%CI:-0.03 and-2.93) level of education(b = 4.12%, 95%CI: 2.73 and 5.5), number of comorbidities(b =-2.41%, 95%CI:-3.89 and-9.41), and level of income(b = 1.98, 95%CI: 0.05 and 3.9), functional limitation(b =-3.59, 95%CI:-2.26 and-4.92) and psychological distress(b =-2.02%, 95%CI:-2.83 and-1.21). Level of education, functional limitation, psychological distress were associated with the score of physical, mental and environmental dimensions, and number of comorbidities was associated with the score of physical and mental dimensions. CONCLUSION Based on our findings, lifestyle modification and increasing facilities of clinics providing service can be effective steps to improve the QOL among people with type 2 diabetes.
