Among successful approaches to cancer immunotherapy, the combination of cytokines application and adoptive transfer of lymphoid effector cells represents the most promising one. To stimulate functional activity of lymphoid cells used for adoptive transfer, some physical factors may be used [1, 2]. It has been shown [1, 3, 4] that the low-energy laser irradiation possesses immunomodulating prope...

We report photoluminescence (PL) measurements on self-assembled GaSb/GaAs quantum dots. As the laser excitation is increased from very low levels, the PL shows a strong red shift, and then a blue shift, such that it presents a U-shaped curve. Raising the temperature causes a large s,100 meVd blue shift of the PL, and shifts the minimum of the PL energy versus laser excitation curve to higher la...

A new heterodyne nano-displacement with error reduction is presented. The main errors affecting the displacement accuracy of the nano-displacement measurement system including intermodulation distortion error, cross-talk error, cross-polarization error and phase detection error are calculated. In the designed system, a He-Ne laser having three-longitudinal-mode is considered as the stabiliz...

Holograms have been recorded in congruent LiTaO(3):Fe with continuous-wave laser light by use of a two-step process. Blue gating light (lambda=488 nm) sensitizes the crystals for holographic recording with red light (lambda=660 nm) of a diode laser. Refractive-index changes of as much as 1.0x10(-5) are achieved for intensities of the red light of 1 W/cm(2) . The saturation values are proportion...

Recently the biostimulatory role of physical methods have been observed in major agricultural crop plants, He-Ne laser is one of the most significant biophysical method for enhancing not only seed germination but also plant growth and development. Seeds of wheat cultivars from Kazakhstan (cultivars; aksay, kazakhstanskaya-10 and eretrospermum-350) and from Egypt (cultivar; sakha-168) were expos...

The proportion of spectrin tetramers and dimers in 4 degrees C low ionic strength extracts of red cell membranes of 9 subjects with 4 different variants of hereditary elliptocytosis (HE) and 2 subjects with hereditary spherocytosis (HS) was determined by nondenaturing gel electrophoresis. Such extracts reflect the native oligomeric state of spectrin in the red cell membrane. In two hemolytic HE...

OBJECTIVE The present study was conducted to investigate the effects of helium-neon (He-Ne) laser irradiation on the proliferation, migration, and differentiation of cultured human epidermal stem cells (ESCs). BACKGROUND DATA A He-Ne laser with a wavelength of 632.8 nm is known to have photobiological effects, and is widely used for accelerating wound healing; however, the cellular mechanisms...

The laser action of Perylene-Red doped in linear, crosslinked, fluorinated and sililated polymeric materials is reported. The purity of dye was found to be a key factor to enhance its solid-state laser behaviour. The samples were transversely pumped at 532 nm, with 5.5 mJ/pulse and 10 Hz repetition rate. Perylene-Red doped copolymers of methyl methacrylate with a 10 vol% proportion of 2,2,2-tri...
