On a possibility of inelasticity partial coefficient K sub gamma determination in pi C and pi Pb interactions at 10 to the 14th power eV (experiment PAMIR 1)

The investigation of hadron-nuclear interactions in Pamir experiment is carried out by means of X-ray emulsion chambers of two types: carbon (C) and lead (Pb). While comparing the results from the chambers of both types it was found a discrepancy in n sub h and E sub h(1)R values. The observed discrepancy in C and Pb chambers is connected with the difference in values of effective coefficients of energy transfer to the soft component K sub eff for C and Pb chambers

Nuclear Interactions Of Super High Energy Cosmic-rays Observed In Mountain Emulsion Chambers

Here we present a summary of joint discussions on the results of three mountain experiments with large-scale emulsion chambers, at Pamir, Mt. Fuji and Chacaltaya. Observations cover gamma quanta, hadrons and their clusters (called "families"). The following topics are covered, concerning the characteristics of nuclear interactions the energy region 1014-1016 eV: (i) rapid dissipation seen in atmospheric diffusion of high-energy cosmic-rays; (ii) multiplicity and Pt increase in produced pi-mesons in the fragmentation region; (iii) existence of large-Pt jets, (iv) extremely hadron-rich family of the Centauro type; (v) exotic phenomena in the extremely high energy region beyond 1016 eV. © 1981.1911125(1977) Acta Univ.

LONG-TERM OUTCOMES IN RHEUMATOID ARTHRITIS IN RELATION TO THE TIME AFTER THE INITIATIONOF BASIC ANTI-INFLAMMATORY DRUG THERAPY

The paper presents the long-term outcomes of rheumatoid arthritis (RA) according to the data of a 15-year prospective follow-up and treatment in 240 patients with the disease. Disease activity resistance (stable remission of more than 2 years, a recurring course with druginduced remissions of 6-18 months, or no remissions), the degree of joint destruction progression, the functional state of patients and their survival were assessed in relation to the time of use of basic anti-inflammatory drugs (BAIDs). In groups 1, 2, and 3, BAID therapy was initiated within the first 5 months of RA, 6-11 and 12-36 months after its onset, respectively. The treatment was monitored, by estimating clinical and X-ray parameters, the functional state of the locomotor apparatus and by correcting the therapy at its stages in the absence of reliable suppression of RA activity and/or with the continuing emergence of new erosions in small joints. The early use of BAIDs under meticulous control of the degree of RA activity suppression and RA progression were shown to frequently achieve clinical and laboratory remissions and to improve functional and life prognosis in the patients

Venous Thromboembolism Prophylaxis in Intensive Care Units (Review)

Venous thromboembolism (VTE) is the third most frequent cause of death from cardiovascular diseases after myocardial infarction and stroke and the most preventable cause of mortality. VTE is common and potentially life-threatening in patients admitted to ICU, even in spite of preventive care.The purpose of the review is to justify the necessity of preventive care for venous thromboembolism in ICU patients.From over 300 initially selected sources of literature databases (Scopus, Web of science, RSCI, etc.), 99 sources were chosen including 69 that were published during the last five years (2015-2020). The exclusion criteria included data of low informative value or disproven data.The review discusses VTE relevance, risk factors for its development, selection and scope of preventive care depending on the risk of thrombosis and hemorrhage, patient management in different clinical settings (impaired renal function, thrombocytopenia, heparin-induced thrombocytopenia, liver dysfunction, indications for installation of vena cava filter).In the world literature, however, there is yet no consensus on the matter under discussion that would have been based on meta-analyses or large randomized studies. No agreement has been reached either in respect of use of mechanical and combined prophylaxis of venous thromboses/PATE, application of ultrasound to detect asymptomatic thromboses. There are no studies on efficacy and safety of pharmacological prophylaxis of VTE in patients with significant hepatic impairment.The review describes that all patients admitted in ICU feature a high risk of VTE development. The scope of preventive care depends not only on VTE risk but also on the risk of a hemorrhage. To prevent the latter, low-molecular weight heparins should be used. For most cases, the choice of heparine dose depends on renal function. When there is a high risk of hemorrhage, mechanical preventive aids are applied
