Published: November 2021

Hajat kebutuhan manusia yang semakin meningkat dan berkembang telah menuntut manusia untuk berinovasi dalam memenuhi kebutuhannya. Hal ini berakibat langsung bagi berkembangnya model-model akad. Akad-akad baru akhirnya muncul di sektor-sektor ekonomi syariah. Diantaranya adalah sekema multi akad mudarabah musytarakah pada asuransi syariah. Implikasi dari model akad baru tersebut salah satu pihak, dalam hal ini adalah perusahaan asuransi mempunyai dua sisi akad atau peran ganda. Perusahaan sebagai pengelola modal (mudārib) sekaligus perusahaan ikut sebagai pemilik modal (sāhib al-māl). Ketika perusahaan mengelola objek mudarabah yang bercampur objek syirkah, maka dimungkinkan terjadi di dalamnya saling tarik-manarik kepentingan, yaitu kepentingan perusahaan sebagai peserta (sāhibul māl) dan satu sisi kepentingan sebagai pengelola (mudārib). Dua sisi akad atau peran ganda mempunyai dasar pendapat mazhab (Hanābilah) sepanjang tidak ada dugaan (at-tuhmah) menyalahi prinsip independensi dan imparsialitas
TROPONIN T AFTER CARDIAC SURGERY: WHAT IS NORMAL? A REVIEW OF THE LITERATURE
Authors: Nellipudi Jessy 
Published: November 2021

It is well established that cardiac biomarkers are universally raised post-cardiac surgery. This is due to various preoperative, intraoperative, and postoperative factors. At present, no reliable tool or model considers intraoperative and postoperative factors to predict morbidity and mortality after cardiac surgery. Troponin T as a single or serial measurement to predict postoperative mortality and morbidity, is an attractive diagnostic tool due to the direct relationship to myocardial damage and the availability of testing. Currently, there is no consensus regarding the expected release of troponin T post-cardiac surgery. From a diagnostic and prognostic point of view, troponin T testing could be beneficial in recognising high-risk patients and any imminent compilations early. Therefore, this review aims to assess the expected release profile and prognostic value of troponin T after cardiac surgery.

Introduction. The production, standardization and quality control process of various dietary supplements containing chelated zinc requires validated quantitative assessment methods. In this work, we propose an X-ray fluorescence spectroscopy (XRF) technique for determining the zinc content in the composition of coordination compounds using the example of a synthesized chelate complex with methionine.Aim. To synthesize Zn(Met)2 chelate complex, to develop and validate a method for its quantitative analysis using the XRF method.Materials and methods. The synthesized zinc chelate complex was investigated by IR spectroscopy. The XRF method was used to develop a method for quantifying the zinc content in the synthesized complex. We used dry mixtures of zinc sulfate monohydrate and L-methionine (Met) in a molar ratio of Zn to Met – 1 : 1, 1 : 2, 1 : 4, 1 : 8 and 1 : 16 and also aqueous solutions of zinc sulfate and L-methionine in a molar ratio of Zn to Met 1 : 2 with Zn concentrations from 0.5 to 100 mmol/l as calibration standards. Complexometric titration was used as an arbitration method for the quantitative determination of zinc content in the samples under study.Results and discussion. The IR spectrum of chelate complex confirmed the presence of a donor-acceptor bond between Zn2+ and the nitrogen atom of amino group in methionine. The titration results showed chelate compounds have a composition corresponding to the stoichiometric formula Zn(Met)2. XRF analysis of dry standard mixed samples demonstrated the presence of matrix effect, that makes impossible an accurate assessment of zinc content in the chelate compound. According to the XRF spectra of aqueous solutions containing zinc sulfate and methionine in a ratio of 1 : 2 at a zinc concentration of 0.5; 1; 2; 3; 4; 5; 10; 25; 50 and 100 mmol/L, a calibration graph was constructed – the dependence of the fluorescence signal intensity for the Kα line of zinc on the concentration of zinc in the solution (r = 0.9996). The method was evaluated by the following validation parameters: specificity, linearity, correctness, precision, and analytical range. The specificity of the validated method was proven in the presence of copper, iron, and silver.Conclusion. The developed method make it possible to determine with sufficient precision and correctness the content of Zn2+ in its aqueous solutions of inorganic and organic nature by the XRF method in the concentration range from 3 to 100 mmol/l without the influence of the matrix.

Published: November 2021

Introduction. Clinical strains of microorganisms, including opportunistic yeast-like fungi (YLF) of the genus Candida, are resistant to currently used antifungal drugs. In this regard, the search for alternative ways to potentiate the activity of antimicrobial agents in relation to the infectious agent is an important and relevant area of research. The study of combinations of existing antimycotic drugs and a medicinal extract of plant origin – farnesol – is one of the promising approaches in the fight against resistant strains of YLF genus Candida. In our previous studies, farnesol has been shown to exhibit relative activity against YLF Candida albicans biofilms. In this study, we used 6 clinical isolates and one museum strain YLF C. albicans to study the effect of farnesol on the antifungal activity of antimycotic drugs.Aim. To prove that farnesol can increase the antifungal activity of certain antimycotics.Materials and methods. To determine the sensitivity of 7 strains of YLF C. albicans to the antimycotic drugs "Nystatin" (NYS 50 µg), "Ketoconazole" (KET 10 µg), "Clotrimazole" (CTR 10 µg), "Amphotericin B" (AMB 10 µg), "Voriconazole" (VRC 10 µg) disk diffusion test was used. A solution of farnesol in concentrations of 100, 50 and 25 µM in a volume of 25 µl was applied to the disk with the antimycotic drug. Sterile physiological (PhS) solution was used as a control (pH 7.0; V = 25 µl).Results and discussion. In 34.3 % of of experiments we can talk about the modulating effect of farnesol solutions on the antifungal activity of antimycotic drugs. In all these cases, the sensitivity of YLF C. albicans to the antimycotic drug increases.Conclusion. The results of this study provide useful information for understanding the mechanism of QS-molecules action with antifungal activity, as well as they are the basis for the practical application of some QS-molecules in the treatment of infectious diseases caused by YLF of the genus Candida. The study demonstrates that farnesol can be recommended as an active substance that improves the sensitivity of YLF Candida to antimycotic drugs, especially in the case of multi-resistant strains Candida.

Introduction. The mineral resource base of Russia has effective sorption substances that meet pharmaceutical requirements. Promising mineral raw materials are Zeolites, which combine the properties of an adsorbent and a "molecular sieve" due to the porous structure. In addition to the enterosorption direction, natural Zeolites are a source of macro-and microelements, which determines their use as biologically active food additives.Aim. Study of the physical and chemical characteristics of the Zeolites of the Kholinsky deposit.Materials and methods. The zeolite mineral raw materials of the Kholinsky deposit were used as objects of research. Optical microscopy was performed using a Leica DM direct microscope (Microsystems, Germany). Energy dispersion analysis was performed using an electron scanning microscope JSM-5300 (Jeol Ltd, Japan). The sorption characteristics were studied using the ASAP 2400 device (Micromeritics, USA) according to the method. The construction of a virtual three-dimensional molecular model of the Zeolite was carried out using the program Java Applet Jmol.Results and discussion. The physicochemical properties of Zeolites are investigated. It is established that morphologically the particles of the zeolite phase have a size of 5-30 microns, they are evenly distributed over the entire area of the site and represent the first structural level. Particles of the zeolite phase with a size of 5-6 microns form the second structural level due to Clinoptilolite crystals, microcracks and microgeodes. Based on the energy-dispersion spectral analysis, an increased content of the elements K, Na was revealed, which indicates the alkaline composition of the cation exchange complex. The studied Zeolite samples have micropores (volume 0.0031 cm3/g), mesopores (volume 0.0675 cm3/g), and a specific surface area of 29.1840 m2/g. A virtual three-dimensional molecular model of the Zeolite of the Kholinsky deposit has been developed. According to the molecular model, the sorption characteristics of the Kholinsky deposit Zeolite were: specific surface area - 1096.31 m2/g (1916.34 m2/cm3), the average diameter of the spherical molecule for adsorption in the pores is 5.97 A.Conclusion. The analysis of the sorption characteristics of the Zeolite revealed the following features: the pores occupy half the volume of the entire Zeolite, which are available for the sorption of water and low-molecular substances. Each pore in three mutually perpendicular directions communicates with the neighboring ones through "windows". A system of intracrystalline pores and cavities is formed, in which the occlusion and adsorption of molecules of the appropriate size easily occurs.

Introduction. E. coli strains are the main microorganisms used for the production of a number of important biopharmaceutical products. There are no natural sources of microwave radiation on Earth, as it is absorbed by the upper atmosphere. No one doubts the importance of studying the biological effect of microwave radiation. The number of publications devoted to this problem is growing every year, and new ideas for the use of microwaves in drug production technology are emerging.Aim. Reveal the main effects of microwave irradiation and develop a technology for microwave intensification of E. coli culture growth.Materials and methods. This study presents the results of atomic force microscopy, refractometry, NMR relaxometry, turbidimetry, and lumimetry, demonstrating the possibility of microwave intensification of the cultivation process.Results and discussion. It was found that microwave irradiation leads to changes in the mobility of protons and the adsorption of water molecules on biopolymers and cells. These are the main links in the mechanism of "non-thermal" microwave action. A single microwave irradiation, depending on a number of parameters, can decrease or increase the growth of biomass. Studies of the bioluminescence of the E. coli strain with the lux-operon have shown that the optimal processing conditions do not negatively affect the luciferase production and metabolic activity of cells. Conclusion. The intensification procedure using microwave radiation can be considered a promising method and can provide new ideas for various applications in biotechnology.
