Abstract:

Natural products of mineral origin (alum, bismuth, calcium, magnesium, silicates and zinc compounds) have maintained their popularity as drugs over the course of time. Some evidence still suggests potential benefit of these substances. Therefore, this paper reviews the characteristic features of the respective minerals and their salts along the course of studies on these products.

Abstract:

Natural killer cells (NK) are innate immune lymphocytes produced in the bone marrow. Isolation of NK cells as a separate population of lymphocytes is related to discovery of their ability to induce the death of tumor cells without prior sensitization. In this review, an attempt was made to systematize the numerous data on the biology of NK cells presented in the literature. The authors consider the stages of NK cells` differentiation from a common lymphoid progenitor (CLP) in the bone marrow, describe two functionally different populations of mature NK cells – CD56brightCDl6- and CD56dimCD16+.

Abstract:

Does natural selection explain why individual organisms have the traits that they do? This question has been the subject of vigorous debate in recent philosophy of biology. Sober and Walsh have defended the thesis that natural selection does not explain why any individual organism has the traits that it does. This thesis, I shall call ‘the Negative View.’ Neander and Matthen have defended the contrary thesis, which I shall call ‘the Positive View,’ according to which natural selection at least sometimes does explain why an individual organism has the traits that it does.

Currently, antibiotic therapy remains the primary method for treating infectious diseases in humans. Nevertheless, its effectiveness is rapidly decreasing due to the widespread emergence of resistant pathogens, necessitating the exploration of new treatment options. One potential approach involves the use of antibiotics in combination with other natural compounds. Aim of the review was to summarize the literature data on the synergy of the antimicrobial action of combinations of antibiotics with various biocides against Gram-positive and Gram-negative pathogenic microorganisms.

These spherules are similar in appearance, but they are quite different in origin. A combined scanning electron microscope, energy dispersive X-ray, X-ray microdiffraction, and electron microprobe analysis enables us to determine their probable origins: phosphatic conodont pearls of biological origin; silicate glass microtektites of terrestrial meteorite-impact origin; and black, magnetic iron spherules of proba

Abstract:

The textile industry is one of the biggest industrial consumers of water especially dye houses which utilize synthetic dyes and other chemicals. Natural dyes are generally environmental friendly and have many advantages over synthetic dyes with respect to production and application. In recent years, there has been an interest in the application of these dyes due to their bio-degradability and higher compatibility with the environment. A review of previous work in the field of applying dyestuffs of natural source as possible textile dyes is given. From an ecological viewpoint, the substitution

Abstract:

Abstract Uterine NK cells (uNK) are a distinct immune population which influence pregnancy outcome. While murine studies have suggested that tissue-resident uNKs predominate in virgin endometrium, the origin of uNKs in humans is unknown. To define subsets of uterine NKs in humans and determine their developmental origin, we performed single-cell RNA-sequencing on CD56+ uNKs sorted from endometrial biopsies of 4 healthy controls (HCs) (17,146 cells) and 5 uterus transplant (UTx) recipients (30,351 cells).

Abstract Natural antibody is constitutively present in the serum of all mammals. This unique IgM plays an important role in the clearance of cellular debris, the early control of viral and bacterial expansion, and the initiation of T-dependent humoral responses. Despite decades of study, the origins of natural antibody have not been precisely defined. Transfer experiments have shown a close correlation between peritoneal cells, including B1a cells, and natural antibody, but peritoneal B1 cells do not secrete adequate amounts of IgM to support the levels found in mouse serum.

Therefore, based on extensive literature research, in this study, the distribution and sources of natural hydrogen were systematically sorted, and the identification method and occurrence state of natural hydrogen were examined and summarized.
