  In vitro drug release in simulated salivary fluid and in vivo taste evaluation in rats were realized to prove taste masking. RESULTS The particle size distribution varied from 266.9 µm to 410.9 µm. The shape of the resulting particles was irregular. The production yield varied from 23.6% to 78.2%.  https://www.selleckchem.com/pharmacological_epigenetics.html  The drug content ranged between 2.3% to 4.8%, encapsulation efficiency increased from 1.6% to 9.0%. In vitro drug release data indicated significant taste masking.  https://www.selleckchem.com/pharmacological_epigenetics.html  CONCLUSION Some of the obtained microparticles by the precipitation method showed satisfactory taste masking efficiency, which proved the taste masking feasibility of this method.

Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) has been identified as the primary cLDL receptor. The soluble form of LOX-1 (sLOX-1) and 3-nitrotyrosine (NT) have recently been suggested as biomarkers of vascular disease. Although type 2 diabetes mellitus (T2DM) is characterised by an increased atherosclerotic risk, the clinical data on cLDL, NT and sLOX-1 levels in T2DM are limited. AIM To explore the possible role of cLDL, NT and sLOX-1 as potential biomarkers for disease progression and complications in poorly controlled T2DM patients with and without microalbuminuria. MATERIALS AND METHODS The serum concentrations of cLDL, NT and sLOX-1 were measured by ELISA in a cross-sectional study of 60 T2DM patients and 35 nondiabetic controls. RESULTS Both the normoalbuminuric (n = 34) and the microalbuminuric (n = 26) patients had significantly higher serum levels of cLDL and NT than the healthy controls, but sLOX-1 was only elevated in the microalbuminuric subgroup (p less then 0.05). Carbamylated LDL correlated positively with NT in the diabetic subjects (rs = 0.266, p = 0.04) while it correlated with urea only in the control group (rs = 0.475, p = 0.004). The serum concentration of sLOX-1 correlated significantly with fasting glucose (rs = 0.441, p less then 0.001), HbA1c (rs = 0.328, p = 0.01) and microalbuminuria (rs = 0.272, p = 0.035) in the whole diabetic cohort. CONCLUSIONS The present study highlights the potential of cLDL, NT and sLOX-1 as possible markers of diabetic complications.

Radiation is known to be able to disrupt certain functions of the tract, modulated by 5-HT-signaling pathways, or the serotonin receptors themselves. AIM The present investigation focused on clarifying the nature and extent of influence of an accelerated electron beam with energy of 9 MeV on the serotonergic mediation of healthy smooth muscle gastric tissue of rats following total body irradiation of the animals. MATERIALS AND METHODS The study involved a control group and two experimental groups of animals exposed to 1 and 5 Gy, respectively, using Siemens Primus S/N 3561. Circular smooth muscle tissues were isolated from rats 1 hour and 18 hours after they were exposed to 1 and 5 Gy and also 5 days after irradiation from the rats that received a dose of 5 Gy in order to investigate the action of exogenous serotonin at increasing concentrations from 10-8 to 10-4 mol/l. The contractile reactivity of each group SM preparations was registered isometrically. RESULTS Electron beams with energy of 9 MeV did not damage the contractile apparatus of gastric SM of rats and had a stimulating effect on contractility resulting from rapidly developing processes (1 hour) or later occurring once (5 days). CONCLUSIONS Difference was observed in the importance of the factors of received dose, lapse of time from irradiation to investigation of SM tissues, and exogenous 5-HT concentration for the changes in SM reactivity in serotonin-induced tonic and phasic responses.

Obesity-related inflammation appears to be a different type of inflammation, mainly due to excessive food intake and unusual homeostasis. It can be evaluated by measuring the concentration of pro- and anti-inflammatory marker molecules – C-reactive protein (CRP), serum amyloid-A (SAA) and interleukin-4. AIM The aim of the present study is to evaluate the rate of the inflammatory process in heart, provoked by the consumption of a high-fat diet. MATERIALS AND METHODS Sixty 8-week-old male Wistar rats were used in this experiment. The laboratory animals were fed orally with two different types of rodent food for 14 or 18 weeks – a high-fat diet (experimental groups) and standard rodent food (control groups). They all were kept under standard housing conditions. The levels of the pro- and anti-inflammatory markers in tissue homogenates from heart were analyzed using ELISA. Their expression in tissue samples was detected immunohistochemically by the biotin-streptavidin-peroxidase method. The total protein concentration was determined by the Lawry method. RESULTS CRP levels showed no significant differences when the control group was compared with the groups fed with a high-fat diet (p>0.05). The SAA levels detected were also insignificantly changed. Only the IL-4 tissue levels showed tendency to increase (p less then 0.05) in the high-fat diet group. CONCLUSIONS Our experiment indicates that there is a specific reaction of the heart to a high-fat diet. It also refers to the existence of adaptive mechanisms allowing the heart to counteract the development of dietary induced inflammation.
