Vibrational spectra of La@C and Ce@C endohedral fullerenes: Influence of spin state multiplicity.

Endohedral fullerenes with paramagnetic encapsulated atoms are new magnetic materials of interest for numerous applications from medicine to quantum computers. An important phenomenon with endohedral fullerenes is the appearance of new vibrational frequencies not associated with empty fullerenes. The vibrational spectra of the lanthanide endohedral fullerenes La@C and Ce@C in various spin states are calculated using the density functional method.

Medulloblastoma therapy generates risk of a poorly-prognostic H3 wild-type subgroup of diffuse intrinsic pontine glioma: a report from the International DIPG Registry.

With improved survivorship in medulloblastoma, there has been an increasing incidence of late complications. To date, no studies have specifically addressed the risk of radiation-associated diffuse intrinsic pontine glioma (DIPG) in medulloblastoma survivors. Query of the International DIPG Registry identified six cases of DIPG with a history of medulloblastoma treated with radiotherapy.

[The Nonlinear Effect of the Composite Influence of Red and Blue Light on Bacteria Escherichia coli Viability].

A non-linear dependence of the inhibition of E. coli cells is found when irradiated simultaneously with the blue and red regions of the spectrum at a power density of 100 mW/cm2. Such dependence is explained by the assumption of a cascade two-photon absorption of light by DNA molecules with an intermediate resonance at cellular chromophores, causing excitation and subsequent DNA damage similar to damage when exposed to UV radiation.

Initial multi-centre observations upon the effect of a new Topical Negative Pressure device upon patient and clinician experience and the treatment of wounds.

Topical Negative Pressure (TNP) has become an accepted intervention in wound healing with a growing body of scientific literature supporting the effectiveness of TNP across a wide variety of wound aetiologies. The range of TNP devices has also increased with perhaps the primary distinction being between those TNP devices that employ gauze or foam as a wound dressing. This study reports preliminary multi-centre observations upon the use of a new gauze based TNP device in the treatment of wounds.

Ultrasoft x-ray Bremsstrahlung isochromatic spectra from 300-2000 eV electrons on Ar and Kr.

For the first time the bremsstrahlung effect was studied experimentally in the spectral region of 6.5-10 nm with 300-2000 eV electron scattering on Ar and Kr atoms. The isochromatic curves displayed maxima at electron energies of approximately = 0.

Nonlinear magnetoacoustic waves in rare-earth orthoferrites.

The dynamics of magnetoacoustic waves in a rare-earth orthoferrite YFeO3 crystal is experimentally investigated. The waves are excited by a high-power laser pulse. The analysis of results is carried out taking into account the nonlinear interaction of oscillation modes.

Tolman's nonlinearity of capillary waves.

A nonlinear theory of nanometer capillary waves is developed that takes curvature dependence of the surface tension coefficient (Tolman's nonlinearity) into account. Estimations are given that indicate the importance of Tolman's nonlinearity for thermocapillary waves.

Effect of laser irradiation on functional activity of human neutrophils: activation of myeloperoxidase in the presence of hematoporphyrin.

Laser irradiation (lambda=540 nm) of the blood increased myeloperoxidase activity in polymorphonuclear leukocytes. We revealed photoinduced activation of myeloperoxidase in irradiated neutrophils in the presence of hematoporphyrin. The photodynamic effect was most pronounced, when the modifier was incorporated into the cell membrane or sorbed on it.
