Introduction. Domestic and foreign works on the milling of complex-profile surfaces with a ball-end tool were analyzed. Methods of surface quality control and ways to provide amplitude parameters of roughness, based on research data and field experiments, were considered. Theoretical provisions on t...

The Asymptotic Giant Branch (AGB) is the late stage of the evolution of intermediate and low-mass stars and is of great importance for understanding stellar evolution, nucleosynthesis, and the chemical evolution of galaxies. This paper systematically reviews the methods for identifying AGB stars, fr...

Objective: to define the diagnostic and predictive value of the markers of fat embolism as a cause of acute lung injury (ALI) in severe concomitant trauma. Subjects and methods: 34 patients with severe concomitant trauma were examined. A dynamic study was undertaken to examine by biochemical tests a...

Diamide derivatives are biologically active molecules that have been widely applied in recent years in research on pesticides, especially insecticides. Using a simple and environmentally friendly scheme, a series of new diamide derivatives containing a trifluoromethylpyridine skeleton was designed,...

A rapid diagnosis of hemostatic disorders in the acute period of severe brain injury was clinically tested by using the continuous automatic recording of resonance oscillations occurring with the formation, retraction, and lysis of a clot. Pathogenetic correction of hemostatic disorders was develope...

Primary gastrointestinal melanoma is a rare tumor with a frequency of 1 new case per 5–7 years. Over the past 100 years, there have been no more than 25 reported cases of primary melanoma of the stomach and colon. The rarity of the disease and nonspecific clinical features pose diagnostic challenges...

Seasonal vaccination against influenza is considered the most effective method of specific prevention of this infection. However, in recent years, the issue of non­specific, training effects of vaccines on the immune system has been widely studied. One of the mechanisms of implementation may be a ch...

A SYBR Green I real-time PCR assay was developed to detect and quantify Plasmodiophora brassicae ribosomal DNA (rDNA) and internal transcribed spacer (ITS). A pair of primers PBF1/PBR1 was designed based on the conservative region of rDNA-ITS of P. brassicae. The positive plasmid pB12 was obtained a...

In this Letter, we systematically investigate the redshift and luminosity distributions as well as the event rates of short gamma-ray bursts (SGRBs) detected by Swift, Fermi, and Konus–Wind satellites. It is found that the distributions of redshift and luminosity of Fermi and Konus–Wind SGRBs are id...

Intracerebral hemorrhage (ICH) is a subtype of stroke associated with high morbidity and mortality rates. No proven treatments are available for this condition. Iron-mediated free radical injury is associated with secondary damage following ICH. Deferoxamine (DFX), a ferric-iron chelator, is a candi...

The Symbiotic star (SySt) is a long-period interacting binary system, typically consisting of a white dwarf (WD) and a red giant surrounded by a nebula. These systems are natural astrophysical laboratories for investigating binary star evolution. In this paper, we identified nine SySts from the Larg...

Materials and methods. This retrospective case-control study enrolled 50 women with severe preeclampsia and 50 control women with spontaneous singleton pregnancy. Median age of women ranged from 20 to 35 years. All women did not have a history of hypertension, autoimmune, metabolic, renal, or cardia...

Abstract Misfolded wild-type superoxide dismutase 1 (disSOD1) protein is implicated in the death of substantia nigra (SN) dopamine neurons in Parkinson disease. Regionally reduced copper availability, and subsequent reduced copper binding to SOD1, is a key factor driving the development of this path...

Trophoblastic neoplasias are rare tumors, accounting for less than 1 % of malignant neoplasms of the female genital tract. Trophoblastic tumors associated with developing pregnancy are extremely rare. The article presents the successful experience of diagnostics and treatment of intraplacental chori...

In this research, we conducted systematic photometric, spectroscopic, and theoretical modeling analyses of two δ Scuti stars—KIC 12602250 and KIC 5768203—that pulsate only in radial modes. We collected their relevant photometric and spectroscopic parameters from multiple catalogs and estimated the a...

Resuscitation during pregnancy is a rare event (one case per 20,000 pregnancies) with a high mortality rate in mothers (about 45%). It is difficult to perform cardiopulmonary resuscitation effectively not only due to specific physiological features of the pregnant but due to difficulties in the deve...

Measurements of the production yields of charm baryons (Λc+) and charm mesons (D0) in proton-lead collisions at a nucleon-nucleon center-of-mass energy of 8.16 TeV are presented. The data were collected in 2016 with the CMS experiment and correspond to an integrated luminosity of 186 nb−1. The Λc+ b...
