[Small cell neuroendocrine carcinoma of the endometrium].

The article describes a rare case of small cell neuroendocrine carcinoma of the endometrium in a 67-year-old woman. According to the literature, only about 90 such observations have been described worldwide. Histological examination revealed three necessary features: the small-cell nature of the tumor, the presence of epithelial and neuroendocrine markers.

Strong Electron-Phonon Coupling and its Influence on the Transport and Optical Properties of Hole-Doped Single-Layer InSe.

We show that hole states in recently discovered single-layer InSe are strongly renormalized by the coupling with acoustic phonons. The coupling is enhanced significantly at moderate hole doping (∼10^{13}  cm^{-2}) due to hexagonal warping of the Fermi surface. While the system remains dynamically stable, its electron-phonon spectral function exhibits sharp low-energy resonances, leading to the formation of satellite quasiparticle states near the Fermi energy.

Influence of gas humidity on the reflection coefficient of multilayer dielectric mirrors.

The influence of water vapor on the reflection coefficient of multilayer mirrors was studied using a gas cell with multiple reflections from the mirrors. A strong change in the reflection coefficient of the mirrors (up to 0.9%) was found when water vapor under a pressure of 23 mbar was injected into the cell, which was interpreted as a change in the refraction index of the layers of multilayer coatings when water vapor penetrated into the porous coating structure.

[Spatial structure of bacterioopsin 87-136 fragment].

The [Nle18]-(87-136)-bacterioopsin, a fragment of bacterioopsin from Halobacterium salinarium synthesized by solid phase technique, was solubilized in a 1:1 chloroform-methanol mixture containing 0.1 M LiClO4 and studied by two-dimensional 1H NMR spectroscopy. The complete assignment of proton resonances was performed in the DQF-COSY, TOCSY, and NOESY spectra of this peptide, and its spatial structure was computed.

[The use of synthetic peptides for detection of antibodies against foot-and-mouth disease virus in the blood from convalescent animals].

Peptides were synthesized, which, according to theoretical analysis of the antigenic structure of protein VP1 of foot-and-mouth disease (FMD) virus types A, 0, and Asia 1, corresponded to potential immunodominant protein sites. Activities of the peptides were studied by solid-phase indirect radioimmunoassay on polyethylene film with purified immunoglobulins against intact FMD virus. Virtually no cross reactions were observed.
