Novel serial imaging methods using scanning electron microscopy may be used for 3D morphological studies of plastic embedded biological specimens. Serial block face SEM has already proven an undisputable position in 3D-EM studies of tissues, but it has a lot of potential in cell biology applications too. Electron tomography can be used to complement those studies where higher resolution is need...

Coronavirus, particularly the genus Betacoronavirus, has been identified as a deadly source of numerous acute respiratory epidemics worldwide, affecting both humans and animals. The includes Covid-19, Severe syndrome coronavirus, Middle East syndrome-related coronaviruses.In contrast, others are expected to have risk transformation such bovine porcine coronavirus. We screened set natural plant ...

How to manage knowledge workers effectively is an important project for most managers. Because of knowledge workers’ different characteristics from common workers, the effective management for them should be based on their unique characteristics. Therefore, a systematic, comprehensive, and pertinent management strategy is necessary.

Nowadays, growing interest in the application of nanotechnology in biomedical and biotechnological fields has opened a new avenue to explore the nanoparticles-biological system interaction. Indeed, a clear gap is still in the cytotoxic effect of NPs on the biological systems. For this purpose, the interaction of the silica oxide nanoparticles (SiO2-NP) with PC12 cell line, as a model of nervous...

  ABSTRACT   Background : Natural uranium exists in earth crust and seawater. The concentration of uranium might increase by human manipulation or geological changes. The aim of this study was to verify susceptibility of laser flourimetry method to determine the uranium concentration in Caspian Sea and Persian Gulf water.   Materials and Methods : Laser flourimetric method was used to determine...

Background: Lactoferrin is a natural biological active cationic protein that can be used as yogurt additive to inhibit the growth of foodborne pathogens. Objectives: The present study evaluated antimicrobial effects lactoferrin against Bacillus cereus, Enterococcus faecalis, and Candida albicans inoculated in laboratory prepared at refrigerator temperature. Methods: pre-warmed skimmed milk was ...

This paper demonstrates a facile method of generating precise serial dilutions in the form of droplets on an open surface platform. The method relies on the use of surface energy traps (SETs), etched areas of high surface energy on a Teflon coated glass substrate, to assist in the magnetic manipulation of droplets to meter and dispense liquid of defined volumes for the preparation of serial dil...
