Inbreeding and high developmental temperatures affect cognition and boldness in guppies ().

Inbreeding impairs the cognitive abilities of humans, but its impact on cognition in other animals is poorly studied. For example, environmental stress (e.g.

Application of zirconium aspartic acid metal-organic framework (MIP-202(Zr)) for high efficient ruthenium adsorption from aqueous solutions.

The zirconium metal - organic framework MIP-202(Zr), based on L-aspartic acid, was prepared by hydrothermal method and used for study of ruthenium adsorption from aqueous solutions. The obtained material was characterized by X-ray diffraction (XRD), infra red spectroscopy (IR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The batch adsorption experiment was performed for determination of adsorption equilibrium, kinetics and thermodynamics parameters to Ru(III) from aqueous solution on MIP-202(Zr).

Crystalline germanium high-Q microresonators for mid-IR.

High-quality-factor optical microresonators have become an appealing object for numerous applications. However, the mid-infrared band experiences a lack of applicable materials for nonlinear photonics. Crystalline germanium demonstrates attractive material properties such as high nonlinear refractive index, large transparency window including the mid-IR band, particularly long wave multiphonon absorption limit.

[Clinical guidelines for male infertility: controversial issues and the need to reach interdisciplinary consensus].

A review of controversial issues about the terminology on male infertility and reproductive function, which is currently used, as well as proposals for updating clinical guidelines for the diagnosis and treatment of male infertility and men in infertile couples are presented in the article. An algorithm is described, the elements of which ensure referral of patients based on the possibility and timing of restoration of reproductive function, taking into account the reproductive health of a woman, as well as increasing the likelihood of successful treatment aimed at the birth of a healthy child.
