Ebook "Ultrashort laser pulses in biology and medicine" gives an overview of biological and medical applications of these laser pulses. The briefness of these laser pulses permits the tracing of the fastest processes in photo-active bio-systems, which is one focus of the book. The other focus is applications that rely on the high peak intensity of ultrashort laser pulses. Examples covered span non-linear imaging techniques, optical tomography, and laser surgery.

This paper was performed to evaluate the photothermal effect of pure gold nanoparticles (Au NPs) prepared by electrochemical method at different voltages, under laser irradiation in the safe wavelength range. The formation, morphological, and structural properties of Au NPs were analyzed by UV-Vis absorption spectroscopy, transmission electron microscopy (TEM), and X-ray diffraction (XRD).

Studying leaves of aquatic and terrestrial populations of Phragmites australis grown on the bank of the Venetian strait of the Dnipro River in Kyiv (Ukraine) for establishing the role of bulliform cells in the mechanisms of plant resistance to moderate soil drought were studied. Bulliform (motor) cells participate in the twisting and folding of leaves during drought and strong sunlight. The study of bulliform cells in the leaves of the aquatic and terrestrial populations of P.

Elucidation of protein transport mechanism in ion exchanges is essential to model separation performance. In this work we simulate intraparticle adsorption profiles during batch adsorption assuming typical process conditions for pore, solid and parallel diffusion. Artificial confocal laser scanning microscopy images are created to identify apparent differences between the different transport mechanisms.

Bladder Cancer (BCa) is a severe genitourinary tract disease with an uncertain pathology. Increasing evidence indicates that the tumor microenvironment plays a decisive role with respect to cancer progression, and that this is driven by tumor cell interactions with stromal components.

A series of polyoxometalate-based magnetic nanoparticles were developed as novel carriers for anticancer drugs. Characterization of the nanoparticles was done by transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), wavelength dispersive X-ray (WDX), and laser particle size analyzer. Epirubicin (EPI) was selected as a model drug. EPI loading efficiency, EPI loading content, and EPI release profiles were studied. Drug loading was controlled using acid-base titration since H + was released during the loading process.

Selective plane illumination microscopy (SPIM a type of light-sheet microscopy) involves focusing a thin sheet of laser light through a specimen at right angles to the objective lens. As only the thin section of the specimen at the focal plane of the lens is illuminated, out of focus light is naturally absent and toxicity due to light (phototoxicity) is greatly reduced enabling longer term live imaging.

This study aimed to exploit laser-induced breakdown spectroscopy, enhanced by nanoparticles (NELIBS), as a fast, sensitive and low-cost technique, to correlate the elemental composition of recent and ancient bovine bone with the elemental composition of the fodder that has been fed to the cattle throughout their life. Biosynthesized silver nanoparticles (BS-Ag NPs) were used to enhance the emission intensity of the spectral lines in the LIBS spectra of contemporary and ancient bovine bones and fodder samples.

The spatial arrangement of functionally important ammonia oxidizing bacteria (AOB) in activated sludge flocs is largely unknown and activated sludge flocs are regarded as heterogeneous agglomerations of bacterial communities. This study aimed to determine both the location of AOB microcolonies within flocs and the size variation of these microcolonies based on their location.

The uptake by mammalian cells of phosphorothioate oli-gonucleotides was compared with that of their respective complexes or conjugates with cationic, cell-penetrating model peptides of varying helix-forming propensity and amphipathicity. An HPLC-based protocol for the synthesis and purification of disulfide bridged conjugates in the 10– 100 nmol range was developed. Confocal laser scanning microscopy (CLSM) in combination with gel-capillary electrophoresis and laser induced fluorescence detection (GCE-LIF) revealed cytoplasmic and nuclear accumula-tion in all cases. ...
