ВИКОРИСТАННЯ МОЛОЧНОЇ СИРОВАТКИ В ТЕХНОЛОГІЇ ОДЕРЖАННЯ БІОМІНЕРАЛЬНИХ ДОБРИВ З ВІДХОДІВ

The relevance of finding new methods for intensifying the process of obtaining biomineral fertilizers in the anaerobic digestion reactor has been pointed out. The efficiency and effectiveness of milk whey for intensifying the process of anaerobic digestion and improving the quality of biomineral fertilizers obtained from waste products have been suggested and experimentally confirmed. In studies for the production of biomineral fertilizers, the following wastes were used in conjunction with milk whey: phosphate containing precipitate after adsorption of phosphates from urban liquid wastes by a natural sunflower husk and condensed active sludge;  cattle manure with addition of precipitates after coagulation of phosphate extraction;  household waste (%: flour – 11, potatoes – 29, apples – 27 and beets – 33) with the addition of precipitates after the coagulation of phosphates; beet pulp. It was found that with an increase in the ratio of "serum: raw materials" in the substrate from 1:4 to 1:1, the content of mineral substances rises from 5,53 to 12,15%. It has been shown and experimentally proved for the first time that the addition of milk whey to raw material (beet pulp) at a ratio of 1: 1 allows shortening the time spent by the products of processing in the reactor for the production of biomineral fertilizers by 1,5-2,2 times. The highest content of nutrients (%: N – 5,2; P – 5,02; K – 10,1; Cа – 9,85) was found in biomineral fertilizer obtained from a phosphate containing precipitate after processing of urban liquid waste with a natural sunflower based adsorbent  husk and sealed active sludge ferrum(III) chloride. The production tests of the obtained biomineral fertilizers in the technology of growing barley of the spring type «Stalker» and «Tsarevich» varieties are carried out.It has been shown that biomineral fertilizers obtained from waste with the addition of milk whey correspond to the current standards ofUkraineon the content of macro- and micronutrients.The relevance of finding new methods for intensifying the process of obtaining biomineral fertilizers in the anaerobic digestion reactor has been pointed out.

Cardiac arrhythmias in patients with bronchial asthma

Introduction. According to modern data, bronchial asthma (BA) is an independent risk factor for the development of cardiac arrhythmias (CA), and the use of long-acting β2-agonists (LABA) in basic therapy may further increase the risks of CA.Aim. To study the structure and risk factors of cardiac arrhythmias in patients with bronchial asthma. Materials and methods. A retrospective study included 181 patients aged 69.4 ± 0.8 years, hospitalized for asthma, with the presence a CA in medical documentation.Results. Among BA patients with CA, supraventricular CA were found in 71.3% (129) patients, ventricular CA in 16.6% (30), combined CA in 12.2% (22). In 52.5% (95) patients, supraventricular extrasystole was detected, in 35.9% (65) – atrial fibrillation, in 28.7% (52) – ventricular extrasystole, in 1.1% (2) – paroxysmal supraventricular tachycardia, in 0.6% (1) – paroxysmal ventricular tachycardia. It was found that supraventricular CA was significantly more frequent among women (χ2 = 5.974, p = 0.05). The severity of BA and the level of control are not related to the type of observed CA (χ2 = 0.755, p = 0.685 and χ2 = 3.003, p = 0.557, respectively).Discussion. The use of a combination of ICS and LABA in basic BA therapy versus the use of ICS alone does not have a significant effect on the frequency and structure of cardiac arrhythmias (χ2 = 1.172, p = 0.556).Conclusion. In hospitalized BA patients, supraventricular cardiac arrhythmias are most often detected, among which supraventricular extrasystole and atrial fibrillation take the main place

Thermal effects of carbonated hydroxyapatite modified by glycine and albumin

In this work calcium phosphate powders were obtained by precipitation method from simulated solutions of synovial fluid containing glycine and albumin. X-ray diffraction and IR spectroscopy determined that all samples are single-phase and are presented by carbonate containing hydroxyapatite (CHA). The thermograms of solid phases of CHA were obtained and analyzed; five stages of transformation in the temperature range of 25-1000°C were marked. It is shown that in this temperature range dehydration, decarboxylation and thermal degradation of amino acid and protein connected to the surface of solid phase occur. The tendency of temperature lowering of the decomposition of powders synthesized from a medium containing organic substances was determined. Results demonstrate a direct dependence between the concentration of the amino acid in a model solution and its content in the solid phase

A combination of chondroitin and glucosamine is widely used in clinical practice as both a symptomatic and structure-modifying agent for the treatment of osteoarthritis (OA). The emergence of new drugs based on this combination substantially expands treatment options for OA therapy.Objective: to evaluate the efficacy and safety of Artroflex® that is a combination of chondroitin sulfate 400 mg and glucosamine sulfate 500 mg (CS + GS) to support joint health in patients with knee and/or hip OA.Patients and methods. When implementing an open observational research program, the results of using the CS + GS complex were assessed in 644 OA patients (74.7% women) (mean age, 58.0±14.6 years) who experienced moderate/severe pain and required to continuously take non-steroidal anti-inflammatory drugs (NSAIDs). The CS + GS complex was prescribed in a dose of 2 capsules per day for 3 months. The investigators estimated changes in pain on movement by a 0 to 10 verbal pain scale, general health (GH) by a 0–10 visual analogue scale), the Lequesne index, the need for NSAIDs, and patient satisfaction with treatment and its tolerance.Results and discussion. After 3-month therapy, there were decreases in pain intensity by 49.2±16.8%, GH scores by 45.6±18.1%, the Lequesne index from 9.0 [6.0; 13.0] to 5.0 [3.0; 9.0]; less than half (45.2%) of the patients still needed for NSAIDs. 82.2% of patients were satisfied or completely satisfied with treatment results; 89.6% reported good treatment tolerance.Adverse events (apparently associated with NSAID use) were recorded in 2.2% of cases. There were no serious complications that required CS + GS treatment discontinuation or hospitalization.Conclusion. The findings have indicated that Artroflex® used to support joint health is an effective agent that controls OA symptoms and has a good safety level.Комбинация хондроитина и глюкозамина широко применяется в клинической практике как симптоматическое и структурно-модифицирующее средство для лечения остеоартрита (ОА).
