1.[The serum level of the morphogenetic protein fibroblast growth factor 23 (FGF-23) as a marker for the efficiency of hyperphosphatemia therapy with phosphate-binding agents in chronic kidney disease].

in English, RussianРеферат Цель исследования. Изучить возможность снижения избыточной продукции фактора роста фибробластов 23-го типа (FGF-23) в сыворотке крови у больных хронической болезнью почек (ХБП) VD стадии путем воздействия на гиперфосфатемию связывающими фосфат препаратами. Материалы и методы. В исследование включили 25 пациентов с ХБП VD стадии, находящихся на регулярном гемодиализе (ГД), 12 — хроническим гломерулонефритом, 8 — тубулоинтерстициальным нефритом и 5 — гипертензивным нефросклерозом; среди них 15 мужчин и 10 женщин в возрасте от 21 года до 65 лет, средний возраст на момент включения в исследование 43±4,5 года. Проводили клиническое, лабораторное и инструментальное обследование, аналогичное таковому у больных с более ранними стадиями ХБП. У всех 25 больных изучен уровень FGF-23 в сыворотке крови (Human FGF-23 ELISA kit с использованием моноклональных антител к полной молекуле FGF-23). Забор цельной крови выполняли через 2 дня после последнего сеанса ГД перед началом очередной процедуры.
2.The potential of circulating extracellular small RNAs (smexRNA) in veterinary diagnostics-Identifying biomarker signatures by multivariate data analysis.
Melanie S1, Benedikt K1, Pfaffl MW1, Irmgard R1. Biomol Detect Quantif. 2015 Sep 19;5:15-22. doi: 10.1016/j.bdq.2015.08.001. eCollection 2015.
Worldwide growth and performance-enhancing substances are used in cattle husbandry to increase productivity. In certain countries however e.g., in the EU, these practices are forbidden to prevent the consumers from potential health risks of substance residues in food. To maximize economic profit, 'black sheep' among farmers might circumvent the detection methods used in routine controls, which highlights the need for an innovative and reliable detection method. Transcriptomics is a promising new approach in the discovery of veterinary medicine biomarkers and also a missing puzzle piece, as up to date, metabolomics and proteomics are paramount. Due to increased stability and easy sampling, circulating extracellular small RNAs (smexRNAs) in bovine plasma were small RNA-sequenced and their potential to serve as biomarker candidates was evaluated using multivariate data analysis tools. After running the data evaluation pipeline, the proportion of miRNAs (microRNAs) and piRNAs (PIWI-interacting small non-coding RNAs) on the total sequenced reads was calculated.
3.[Preparation characterization and antitumor activity in vitro of berberine hydrochloride polymeric micelles].
Ma WZ, Wang JL, Tu PF. Zhongguo Zhong Yao Za Zhi. 2015 Nov;40(21):4182-8.
With polyethylene glycol vitamin E succinate (TPGS) as the carrier materials, and berberine hydrochloride ( BER) as model drug, we formed berberine hydrochloride (BER) -loaded TPGS nanomicells (BER-PMs) using filming-rehydration method to improve its solubility and in vitro anti-tumor effect. The transmission electron microscope (TEM) was used to observe the particle appearance; particle detector was used to detect the diameter and Zeta potential; and ultracentrifugation was utilized to determine the encapsulation efficiency (EE) and drug-loading (DD); dynamic dialysis method was used to study the in vitro release behavior of BER-PMs, and the anti-tumor activity against MCF-7 cells was determined by MTT method. Results showed that the average particle size of BER-PMs was (12.45 ± 1.46) nm; particle size was uniform and spherical; drug loading and encapsulation efficiency were (5.7 ± 0.22)% and (95.67 ± 5.35)%, respectively. Zeta potential was (-1.
4.Synthesis, cyclooxygenase inhibition and anti-inflammatory evaluation of new 1,3,5-triaryl-4,5-dihydro-1H-pyrazole derivatives possessing methanesulphonyl pharmacophore.
Abdellatif KR1, Elsaady MT2, Abdel-Aziz SA3, Abusabaa AH3. J Enzyme Inhib Med Chem. 2016 Apr 12:1-11. [Epub ahead of print]
A new series of 1,3,5-triaryl-4,5-dihydro-1H-pyrazole derivatives 13a-p were synthesized via aldol condensation of 3/4-nitroacetophenones with appropriately substituted aldehydes followed by cyclization of the formed chalcones with 4-methanesulfonylphenylhydrazine hydrochloride. All the synthesized compounds were evaluated for their cyclooxygenase (COX) inhibition, anti-inflammatory activity and ulcerogenic liability. All compounds were more potent inhibitors for COX-2 than COX-1. While most compounds showed good anti-inflammatory activity, compounds 13d, 13f, 13k and 13o were the most potent derivatives (ED50 = 66.5, 73.4, 79.8 and 70.5 μmol/kg, respectively) in comparison with celecoxib (ED50 = 68.1 μmol/kg). Compounds 13d, 13f, 13k and 13o (ulcer index = 3.89, 4.86, 4.96 and 3.92, respectively) were 4-6 folds less ulcerogenic than aspirin (ulcer index = 22.75) and showed approximately ulceration effect similar to celecoxib (ulcer index = 3.
