The work was carried out by microinjections of an aromatase inhibitor letrozole, an estrogen receptor modulator tamoxifen in incubated eggs Gallus g. domesticus, the first day of incubation. It also used 5-azacytidine (5-AC) at the same time. Injection of progesterone was carried out before the onset of meiosis prophase 1 on 16 h of incubation. Morphologically and histologically and by PCR, sex of the 17-day embryos was controlled. According to information received microinjection of letrozole caused almost a 100% inversion of genetic males to females, which is manifested in the morphology of the gonads. In other experiments, sex reversal is not revealed. The results are obtained in this study, and the data suggest that the presence of gonadogenesis in female chickens makes earlier emergence of aromatase in the beginning of incubation, than that according to the classical scheme of sex determination in birds. Presumably this kind of synthesis is triggered by some W-chromosomal factors. It failed to detect the phenomenon of gender inversion—the transformation of males into females after exposure to demethylating agent 5-AC that casts doubt on the participation of male hypermethylated (MHM)-RNA-segment in regulating the activity of sex determining genes.

AIM： To study isolation and chemical characterization of pectin derived from the common cranberry vaccin/um oxycoccos L. （oxycoccusan OP） and the testing of its preventive effect on experimental colitis. METHODS： Mice were administrated orally with OP two days prior to a rectal injection of 5% acetic acid and examined for colonic damage 24 h later. Colonic inflammation was characterized by macroscopical injury and enhanced levels of myeloperoxidase activity measured spectrophotometrically with o-phenylene diamine as the substrate. The mucus contents of the colon were determined by the Alcian blue dye binding method. vascular permeability was estimated using 4% Evans blue passage after i.p. injection of 0.05 mol/L acetic acid. RESULTS： In the mice treated with OP, colonic macroscopic scores （1.1 ± 0.4 vs 2.7, P 〈 0.01） and the total square area of damage （10 ± 2 vs 21 ± 7, P 〈 0.01） were significantly reduced when compared with the vehicle-treated colitis group. OP was shown to decrease the tissue myeloperoxidase activity in colons （42 ± 11 vs 112 ± 40, P 〈 0.01） and enhance the amount of mucus of colitis mice （0.9 ± 0.1 vs 0.4 ± 0.1, P 〈 0.01）. The level of colonic malondialdehyde was noted to decrease in OP-pretreated mice （3.6 ± 0.7 vs 5.1 ± 0.8, P 〈 0.01）. OP was found to decrease the inflammatory status of mice as was determined by reduction of vascular permeability （161 ± 34 vs 241 ± 21, P 〈 0.01）. Adhesion of peritoneal neutrophils and macrophages was also shown to decrease after administration of OP （141 ± 50 vs 235 ± 37, P 〈 0.05）. CONCLUSION： Thus, a preventive effect of pectin from the common cranberry, namely oxycoccusan OP, on acetic acid-induced colitis in mice was detected. A reduction of neutrophil infiltration and antioxidant action may be implicated in the protective effect of oxycoccusan.

A plasma-assisted catalytic reactor was used to remove nitrogen oxides (NOx)from diesel engine exhaust operated under different load conditions. Initial studies were focused onplasma reactor (a dielectric barrier discharge reactor) treatment of diesel exhaust at varioustemperatures. The nitric oxide (NO) removal efficiency was lowered when high temperature exhaust wastreated using plasma reactor. Also, NO removal efficiency decreased when 45% load exhaust wastreated. Studies were then made with plasma reactor combined with a catalytic reactor consisting ofa selective catalytic reduction (SCR) catalyst, v_2O_5/TiO_2. Ammonia was used as a reducing agentfor SCR process in a ratio of 1:1 to NOx. The studies were focused on temperatures of the SCRcatalytic reactor below 200℃. The plasma-assisted catalytic reactor was operated well to remove NOxunder no-load and load conditions. For an energy input of 96 J/l, the NOx removal efficienciesobtained under no-load and load conditions were 90% and 72% respectively at an exhaust temperatureof 100 ℃.

We report and discuss the results of x-ray radiation measurements in theSino-Russian joint Z-Pinch experiments on Angara-5-1 facility with a load current of 2.5-3.6MA. Themeasurements were conducted by using an x-ray power meter (XRPM) and a time-resolved one-dimensionalx-ray imaging system developed in China Academy of Engineering Physics. The experimental resultsindicate that an x-ray power-platform prior to a main peak and a less intensive sub-peak after themain peak in the waveform exist for the nested-wire array implosions, and the radiation process isrelatively faster than that in the case of the single array. Laser shadowgraph of the implodingplasma suggests that the prior power-platform is a result of the collision of the inner-outer plasmalayers. The faster radiation process of nested array implosion can be explained by analysing thecorresponding result of the time-resolved one-dimensional imaging system, which demonstrates abetter axial imploding uniformity and synchronization. In comparison with x-ray diode, the XRPMyields a higher height of x-ray power-platform due to its flat energy response. The sub-peak afterthe main peak is proposed to be a result of the later-time additional implosion of plasma.

The nail plate forms a barrier that limits the effectiveness of drug delivery in the treatment of nail diseases and prevents the outflow of fluid in the case of subungual hematoma formation. Microperforation of the nail plate through laser radiation can increase the effectiveness of drug delivery and ensure the possibility of blood outflow. This study detected and identified the type and threshold of effects that arise from exposing the nail plate to Yb,Er： Glass （λ = 1.54 μm） and Er：YLF （λ= 2.81 μm） laser radiation. The rate and efficiency of nail plate ablation by the radiation of these lasers were studied. The effect of the storage time of a freshly extracted nail plate in open air on its ablation rate by Er：YLF （ λ=2.81 μm） laser radiation was also investigated. The impact of the Yb,Er：Glass and Er：YLF laser pulses on the nail plate caused bleaching, carbonization, ablation with microcrater formation, and microperforation. The laser energy densities WE （thresholds） required for these effects were determined. The maximum ablation rate for Yb,Er：Glass laser radiation was 8 μm/pulse at WE = 91 ±2 J/cm2, whereas that for Er：YLF laser radiation was 12 μm/ pulse at WE= 10.5＋0.5 J/cm2. The maximum ablation efficiency for Yb,Er：Glass laser radiation was 0.1 μm/mJ at Ws = 10.5±0.5 J/cm2, whereas that for Er：YLF laser radiation was 4.6 μm/mJ at WE = 5.3±0.3 J/cm2. The laser ablation rate depends on the storage time and conditions of the freshly extracted nail plate. For example, when exposed to Er：YLF laser radiation, the laser ablation rate decreased by half from the initial maximum value in 96 h of air storage and returned to the initial value after 1 h of storage in distilled water.

The effect of complete social deprivation in early postnatal ontogenesis on adult behavior in Wag/Rij rats with a genetic predisposition to the development of absence epilepsy was studied. From the 2nd to the 8th day of life, a 3-hour daily isolation of the pups from the mother and siblings was performed, the control animals were handled. In adulthood, offspring behavior was tested in an elevated plus-maze, an open field, and for an ability to learn the conditioned reflex of active avoidance. In isolated earlier rats, an increase in emotional reactivity, exploratory behavior in a potentially dangerous space, the speed of learning a conditioned reflex with negative painful reinforcement, and a disturbance of the formation of a defensive reaction were revealed. It is assumed that high emotional reactivity creates the prerequisites for the development of absence epilepsy.
