The Peri-Caspian Lowland megabasin is a vast region of ancient salt accumulation that occurred during the Permian period. The territory over which the salt domes were formed gave rise to and accumulated huge resources of subterranean brackish and salted waters within the hypergenesis zone that also included brine and mineral mud lakes containing chemical elements of great therapeutic value. Nowadays, the subterranean waters (leaches, pools, and springs) provide the sources of the mineral-rich materials of balneological significance, such as sulfide, bromine, and boron-containing mineral waters the ion and mineral composition of which together with the high degree of mineralization makes them highly valuable for medicinal applications...

We demonstrate a low-cost optical method for measuring the gloss properties with improved sensitivity in the low gloss regime, relevant for skin gloss properties. The gloss estimation method is based on, on the one hand, the slope of the intensity gradient in the transition regime between specular and diffuse reflection and on the other on the sum over the intensities of pixels above threshold, derived from a camera image obtained using unpolarized white light illumination. We demonstrate the improved sensitivity of the two proposed methods using Monte Carlo simulations and experiments performed on ISO gloss calibration standards with an optical prototype...

Photodynamic therapy becomes a widely spread method due to cancer growth in the world. However, to detect tumors at early stages, it is necessary to carry out diagnostic measures in a timely manner. Our aim was to test the developed pharmaceutical composition, which can be used for external application in early fluorescent diagnostics even in the absence of visual changes, as well as for therapy effectiveness control. Pharmacokinetic studies on laboratory animals and volunteers were carried out. The results have shown that the dipotassium salt of Yb3+-dimethoxyhematoporphyrin IX, which is highly soluble in water and stable in storage, is a promising marker for earlier diagnostics of tumors and can be used in dermatology, dentistry, gynecology, cosmetology, ear, nose, and throat diseases, veterinary, and in other areas of medicine...

In recent years, emphasis on the physical examination has made way for a plethora of laboratory tests and sophisticated imaging diagnostic techniques. In addition, we are witnessing an underestimation of dermatology as a specialty around the world, which is accepted as an ambulatory specialty on the border of cosmetology and beautification. However, recognizing specific cutaneous clinical signs can facilitate timely diagnosis of various systemic infections and neoplastic diseases. Thus, a skilled dermatologist can play an essential role in the multidisciplinary team, involved in the care for systemically ill patients...

The review is devoted to an actual problem of cosmetics in gerontology, one of molecular aspects of skin aging. Cell renewal processes slow down with aging, and the proliferation apoptosis ratio shifts towards cell death. One of the most pivotal apoptotic markers is the transcription factor p53. p53 protein expression in the skin keratinocytes increases under the influence of ultraviolet radiation. Wherein when exposed to ultraviolet radiation mutant forms of p53 have been revealed in 70 % of keratinocytes...
