Your molecular foundation of combining among poly(Any)-tail length as well as translational efficiency.
In people with a brachymorphic skull, a wider type of the facial section and, accordingly, of the maxilla is observed, in skulls with a meso- and dolichomorphic form of structure, on the contrary, the middle and narrow type of the maxilla is more common.In this review, we have discussed the relationships between oral squamous cell carcinoma (OSCC) and dental implants. In the last decade, dental implants have been widely used for the treatment of complete or partial edentulism. Despite the fact that they have seen incredible success and the use of dental implants increases, concerns over safety and efficiency is rising as well. The literature analysis has shown that the number of reported cases when the OSCC development is associated with peri implantitis is gradually increasing. The possibility of squamous cell carcinoma development must be considered when evaluating the peri-implantitis. We highly recommend periodic oral and radiographic examination after the implant placement. The patients with peri-implantitis that do not respond to conventional treatment methods, and the patients who have a severe or rapid progression of peri-implantitis require biopsy. The histopathological examination will aid with the differential diagnosis between peri-implantitis and OSCC, and hence, provide the correct diagnosis.The objective of the study was to assess antibacterial activity of antibiotic-impregnated bone allograft processed according to the Marburg bone bank system. In the experiment, thermal processed bone allografts according to the Marburg bone bank system were used. They were impregnated with gentamicin. Four groups are formed depending on the impregnation method. In I and II groups, an entire femoral heads and, in III and IV perforated femoral heads were used. In groups I and III, antibiotic impregnation was carried out simultaneously with the thermal disinfection, and in groups II and IV after thermal disinfection. In the control group, the bone allografts were heat treated, then impregnated with saline. The antibiotic release was evaluated by agar diffusion test against Staphylococcus aureus, Pseudomonas aeruginosa and Klebsiella pneumonia. The results of the study indicate the presence of antimicrobial activity against S. aureus, P. aeruginosa and K. pneumonia in all groups except the control group. However, in the II and IV group, the inhibition zone was higher compared with the I and III groups (p less then 0.05). We conclude that the capacity of bone allografts processed according to the Marburg bone bank system to act as gentamicin carriers has been confirmed in this study. Gentamycin loaded perforated bone allograft (IV group) showed statistically higher efficacy against S. aureus, P. aeruginosa and K. pneumonia among studied groups.In humans and mammals, the homeostasis system is supported by many organs and systems, but hematopoietic remains one of the most important. A negative effect on the hematopoietic system is rejected by many factors, but the first place remains for drugs, which one in three are non-steroidal anti-inflammatory drugs (NSAIDs). The most popular among them remains the active substance "Diclofenac Sodium", which is part of many drugs. The purpose of the work is to study the action of the active substance Diclofenac sodium and its effect on the erythrocyte series of bone marrow cells of white laboratory mice in an experiment. The studies were conducted on white laboratory mice, males, 6 months old, 60 grams. The animals were divided into three groups, the first received 0.09 mg of Diclofenac sodium in the quadriceps of the thigh, the second - 0.18 mg and the third physiological solution for 96 hours. check details After observing all the rules of bioethics, the animals were slaughtered and the bone marrow was examined using pure immuno-magnetic separation techniques. During the study, it became known that in the first group the number of erythroblasts increased by 75%, while in the second group by 166.5%, due to the blocking of differentiation into more mature cells. The number of reticular cells decreased by 33.4%, while in the second group by 60%. A decrease in the erythrokaryocyte maturation index in the first group by 42.6% whereas in the second by 32.5%, primarily due to immature red blood cell precursors. In the first group, the leuko-erythrokaryoid ratio decreased by 9.5%, while in the second group by 12.3%. The number of megakaryocytes due to the predominant blockade of cyclooxygenase-2 increased in the first group by 266.6%, while in the second by 733.3%. It was found that the most favorable effect on red bone marrow cells has a dose of 0.09 mg, while 0.18 mg has a toxic effect and contributes to the development of cardiovascular complications.In medical literature is known that the electromagnetic waves own a harmful effect on human organism. Is convinced shows that surround household microwave oven exist certain quantity of non-ionizing radiation leak. The aim of the present work is study the effect of non-ionizing radiation, emitted by household microwave oven, on the body weight, emotional and locomotor activity and cortisol blood plasma level in rats. 6 weeks Wistar rats cage were placed near microwaves oven, from closed door escape 727,24±84,55 Mw/m² Power Density microwaves. The oven was switch over two times a day for 3-3 minutes during 10 days. Experimental and control group rats are weighed before and after experiment. To assess the emotional state and locomotor activity open field test was performed and for determine stress level the concentration of plasma cortisol was measured. It was found that after 10 days, in microwave radiation exposure group rat body weight gain increase more than in control group. In open field test, microwave radiation exposure group rats spent more time in center square than control group rats, line crossings, center square entries, stretch attend postures are also more in microwave radiation exposure group rats than in control. Cortisol level in plasma were increased in microwave radiation exposure group rats than in control group. Complete analysis of our results have convinced shown the necessary to study of household microwave oven non-ionizing radiation.
