The proposed work aims to study phenol components （flavonoids） of bee bread and pollen obtained in Georgia using the HPLC （high-performance liquid chromatography） method, and to determine the content of biologically active compounds in them. The samples were taken in lmereti region （west Georgia）. After extraction of samples, there were carried out spectral and HPLC analysis of compounds for the sake of qualitative and quantitative research of them. There are studied the flavonoid compounds of bee bread and pollen by using the HPLC methods, and naringin, rutin and quercetin are identified. Their amount counts about 20% of full content of flavonoids. The content of flavonols in bee bread and pollen has been established. It also has been determined that the amount of flavonoids during the storage period of products reduces to 6.17-5.03 ***-1.

AIM To evaluate the real-world effectiveness of golimumab in ulcerative colitis(UC) and to identify predictors of *** We conducted an observational, prospective and multi-center study in UC patients treated with golimumab, from september 2014 to september 2015. Clinical activity was assessed at wk 0 and 14 with the physician's global clinical assessment(PGA) and the partial Mayo score. Colonoscopies and blood tests were performed, following daily-practice clinical criteria, and the results were recorded in an sPss *** Thirty-three consecutive patients with moderately to severely active UC were included. Among them, 54.5% were female and 42 years was the average age. Thirty percent had left-sided UC(E2) and 70% had extensive UC(E3). All patients had an endoscopic Mayo score of 2 or 3 at baseline. Twenty-seven point three percent were anti-tumor necrosis factor(TNF) treatment na?ve, whereas 72.7% had previously received infliximab and/or adalimumab. sixty-nine point seven percent showed clinical response and were steroid-free at wk 14(a decrease from baseline in the partial Mayo score of at least 3 points). Based on PGA, the clinical remission and clinical response rates were 24% and 55% respectively. Withdrawal of corticosteroids was observed in 70.8% of steroid-dependent patients at the end of the study. Three out of 10 clinical non-responders needed a colectomy. Mean fecal calprotectin value at baseline was 300 μg/g, and 170.5 μg/g at wk 14. Being anti-TNF treatment na?ve was a protection factor, which was related to better chances of reaching clinical remission. Twenty-seven point three percent of the patients required treatment intensification at 14 wk of followup. Only three adverse effects(AEs) were observed during the study; all were mild and golimumab was not *** This real-life practice study endorses golimumab's promising results, demonstrating its short-term effectiveness and confirming it as a safe drug during t

The ternary compound barium aluminosilicate BaAl2si2O8, known as celsian, a non-wetting additive that increases the corrosion resistance of refractor） materials against molten aluminum, was incorporated into the matrix of a high-alumina low cement castable after its synthesis using barite and a low cost source of alumina and silica. This paper presents the influence of this phase on the wetting angle formed between liquid aluminum alloy and solid refractory castable surface.

To conduct regional climate change assessment for the selected location (Tbilisi) more than century period hydrometeorological observation data of day-night minimal temperature is used. In the presented paper only temperature negative values of whole winter season are used. The temperature field change is characterized by the following four parameters: the minimal temperature sum (winter-day temperature is less than zero) of winter frost days;frost day number;season minimal temperature and the occurrence date of season minimal temperature. The modular structure of the above listed parameters has been studied and the mathematical expressions for temporal changes of those parameters have been obtained considering dynamical norms and cyclical changes. The intensity of this change in terms of global warming has been determined. One of the main parameters determining climate change is the variations of temperature field. Despite the fact that this parameter has been modified in the large range due to numerous impacts, they kept stable and provide sustainable equilibrium of the Earth’s energy potential during long-term (several decades) period. This was the reason why the Earth climate remained unchained. As it is known, the anthropogenic impact on the environment has breached the sustainable balance of the Earth energy potential, the potential has been gradually grown almost for more than a century and is known by the name of global warming. The above-mentioned process has already created the greatest threat to the existence of Earth’s biosphere and if it still continues the catastrophic results eventually have to be expected. This led that the problem solving has been set as an urgent task. The numerous fundamental studies for all regions of the world have been carried out to assess the intensity of this process.

Four cases of proximal femoral focal deficiency (PFFD) in an otherwise healthy infant are described. Antenatal diagnosis was made at 27, 23, 23 and 18 weeks of gestation by routine ultrasound (Us) examination. Computer Tomography (CT) was performed after 30 weeks of gestation and confirmed the images obtained by Us. The diagnosis was confirmed after delivery. These cases illustrate the importance of combining Us and CT to improve accuracy of prenatal diagnosis of skeletal disorders.
