Note that the limit on EMF should be expressed in terms of its EMF spectral density rather than as a total EMF over each of a series of separate bands. If all devices limit their own EMF spectral density, in the spectral region where they are active, in such a way that total EMF spectral density is below the regulated limit in that region, then it is certain that the aggregate EMF spectral density will be below the regulated limit at all frequencies.Microbiology; Bacteria; Antimicrobial; Infectious disease; Medical microbiology; Pharmacology; Pneumonia; Acinetobacter baumannii; Colistin.Objective Restoring noncarious cervical lesions are challenging to clinical practice. This study aimed to compare the clinical performance/longevity of glass ionomer cements (GIC) and composite resins (CR) used for noncarious cervical lesions (NCCL) through a systematic review and meta-analysis (MA). Data Randomized and controlled clinical trials and nonrandomized clinical trials, which compared the clinical performance/longevity of CR and GIC (conventional and/or resin-modified) in the treatment of NCCL, were included. this website Source The methodological quality and risk of bias were evaluated using the Cochrane Collaboration tool. Seven MAs were performed considering (1) the clinical performance of the parameters in common retention, marginal discoloration, marginal adaptation, secondary caries, color, anatomic form, surface texture and (2) a follow-up time of 12, 24 and 36 months. The prevalence of successful restorations and the total number of restorations per clinical parameter/follow-up time were used to calculate the relative risk (95% CI). Study selection After screening of the studies, 13 studies were used for quantitative synthesis. The risk difference (CI 95%, α, I2) between GIC and CR for anatomic form was 0.00 (-0.02, 0.02; p = 0.83; 0%); for color was -0.02 (-0.08, 0.04; p = 0.48; 80%); for surface texture was -0.02 (-0.06, 0.02; p = 0.31; 63%); for secondary caries was -0.00 (-0.01, 0.01; p = 0.87; 0%); for marginal discoloration was 0.01 (-0.01, 0.03; p = 0.23; 3%); for marginal adaptation was 0.01 (-0.01, 0.04; p = 0.34; 32%) and for retention was 0.07 (0.02, 0.12; p = 0.003; 76%). Conclusion GIC showed a clinical performance significantly higher than CR in regard to retention, whereas for the other parameters, GIC was similar to CR. Clinical significance NCCLs is increasingly prevalent among the population and this type of lesion causing defects in the tooth that affect not only aesthetics but also everyday habits, such as drinking, eating and teeth brushing, due to the sensitivity these lesions cause.Neuromedin U (NMU) is a bioactive neuropeptide, highly distributed in the gastrointestinal tract and the central nervous system. NMU has various physiological functions related to feeding behavior, energy metabolism, stress responses, circadian rhythmicity and inflammation. Recently, several reports indicate that the central NMU system plays an important role in the reward systems in the brain. However, the underlying molecular mechanisms are not yet fully defined. In this study, we found that some of cocaine-induced c-Fos immunoreactive cells were co-localized with NMU in the nucleus accumbens (NAc), caudate putamen (CPu), and basolateral amygdala (BLA), which are key brain regions associated with the brain reward system, in wild type mice. Whereas, a treatment with cocaine did not influence the kinetics of NMU or NMU receptors mRNA expression in these brain regions, and NMU-knockout mice did not show any higher preference for cocaine compared with their control mice. These results indicate that cocaine has some effect on NMU expressing neurons related to the brain reward system, and this suggests NMU system may have a role on the brain reward systems activated by cocaine.Cerebroneurovascular trauma is recognized as an important risk factor in the development of seizure and epilepsy. Administration of citicoline in these situations is a conventional therapeutic strategy, which combines neurovascular protection and repair effects. The aim of the present study is clarifying the effect of acute and sub-chronic citicoline administration on pentylenetetrazole (PTZ) and electroshock induced seizures in mice. Besides we examined the probable role of NO and its interaction with citicoline in seizure experiments. Male mice were received acute and sub-chronic regimens of different doses of citicoline (62.5, 125, 250 and 500 mg/kg) before the intravenous or intraperitoneal PTZ-induced seizures or electroshock. To clarify the probable role of NO, 7-nitroindazole (7-NI) (60 mg/kg) or aminoguanidine (AG) (100 mg/kg) were injected 5 min before citicoline in separate groups. The results revealed that neither acute nor sub-chronic treatment with citicoline could affect the seizures induced by intravenous or intraperitoneal PTZ, but in electroshock model, citicoline showed anti-epileptic properties. Co-administration of citicoline and selective nitric oxide synthase (NOS) inhibitors amplified the anticonvulsant effect of citicoline. The current results indicated that citicoline has anticonvulsant effects probably through the inhibition of NO.This work used quantum chemical method via DFT to calculate molecular descriptors for the development of QSAR model to predict bioactivity (IC50- 50% inhibition concentration) of the selected 1, 2, 3-triazole-pyrimidine derivatives against receptor (human gastric cancer cell line, MGC-803). The selected molecular parameters were obtained by B3LYP/6-31G∗∗. QSAR model linked the molecular parameters of the studied compounds to their cytotoxicity and reproduced their observed bioactivities against MGC-803. The calculated IC50 tailored the observed IC50 and greater than standard compound, 5-fluorouracil, suggesting that the developed QSAR model reproduced the observed bioactivity. Statistical analyses (including R2, CV. R2 and R a 2 gave 0.950, 0.970 and 0.844 respectively) revealed a very good fitness. Molecular docking studies revealed the hydrogen bonding with the amino acid residues in the binding site, as well as ligand conformations which are essential feature for ligand-receptor interactions. Therefore, the methods used in this study are veritable tools that can be employed in pharmacological and medicinal chemistry researches in designing better drugs with improve potency.
