Vibrational spectroscopy of GdCr3(BO3)4: Quantitative separation of crystalline phases

This work is devoted to the investigation of GdCr3(BO3)4 crystals by the method of infrared spectroscopy. Incongruently melting borate GdCr3(BO3)4 was obtained as a result of spontaneous crystallization. Crystal structures were identified by the method of infrared spectroscopy. Ab initio calculations in the frame of density functional theory enabled us to separate modes belonging to the R32 and C2/c phases and to estimate the ratio of these phases in GdCr3(BO3)4 crystals. We have found that the content of the rhombohedral R32 (non- centrosymmetric) modification is about 85%. © Published under licence by IOP Publishing Ltd

The alpha 7 nicotinic receptor agonist PHA-543613 hydrochloride inhibits <i>Porphyromonas gingivalis</i>-induced expression of interleukin-8 by oral keratinocytes

Objective: The alpha 7 nicotinic receptor (α7nAChR) is expressed by oral keratinocytes. α7nAChR activation mediates anti-inflammatory responses. The objective of this study was to determine if α7nAChR activation inhibited pathogen-induced interleukin-8 (IL-8) expression by oral keratinocytes.&lt;p&gt;&lt;/p&gt; Materials and methods: Periodontal tissue expression of α7nAChR was determined by real-time PCR. OKF6/TERT-2 oral keratinocytes were exposed to &lt;i&gt;Porphyromonas gingivalis&lt;/i&gt; in the presence and absence of a α7nAChR agonist (PHA-543613 hydrochloride) alone or after pre-exposure to a specific α7nAChR antagonist (α-bungarotoxin). Interleukin-8 (IL-8) expression was measured by ELISA and real-time PCR. Phosphorylation of the NF-κB p65 subunit was determined using an NF-κB p65 profiler assay and STAT-3 activation by STAT-3 in-cell ELISA. The release of ACh from oral keratinocytes in response to &lt;i&gt;P. gingivalis&lt;/i&gt; lipopolysaccharide was determined using a GeneBLAzer M3 CHO-K1-blacell reporter assay.&lt;p&gt;&lt;/p&gt; Results: Expression of α7nAChR mRNA was elevated in diseased periodontal tissue. PHA-543613 hydrochloride inhibited &lt;i&gt;P. Gingivalis&lt;/i&gt;-induced expression of IL-8 at the transcriptional level. This effect was abolished when cells were pre-exposed to a specific α7nAChR antagonist, α-bungarotoxin. PHA-543613 hydrochloride downregulated NF-κB signalling through reduced phosphorylation of the NF-κB p65-subunit. In addition, PHA-543613 hydrochloride promoted STAT-3 signalling by maintenance of phosphorylation. Furthermore, oral keratinocytes upregulated ACh release in response to &lt;i&gt;P. Gingivalis&lt;/i&gt; lipopolysaccharide.&lt;p&gt;&lt;/p&gt; Conclusion: These data suggest that α7nAChR plays a role in regulating the innate immune responses of oral keratinocytes.&lt;p&gt;&lt;/p&gt

PECULIARITIES OF THE KRASNODAR REGION’S TEENAGERS’ NEUROLOGICAL STATUS

The aim of this scientific work is detecting of neurological pathology among first grade students. We examined 2507 students (1414 male and 1093 female) in the age from 16 to 18 in the process of deep medical examination. We collected neurological complains, neurostatus, analyses of medical documentation. This data was statistically handled. Therefore 80% of students had neurological pathology. The most frequent cases were vegetative-vascular dystonia, vertebrogenic pathology and essential headache. The gained data means the very high level of neurological disease among students, which shows not only importance of rehabilitation activities, but modernization of preventive activities among adolescences

Future therapeutic targets in rheumatoid arthritis?

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by persistent joint inflammation. Without adequate treatment, patients with RA will develop joint deformity and progressive functional impairment. With the implementation of treat-to-target strategies and availability of biologic therapies, the outcomes for patients with RA have significantly improved. However, the unmet need in the treatment of RA remains high as some patients do not respond sufficiently to the currently available agents, remission is not always achieved and refractory disease is not uncommon. With better understanding of the pathophysiology of RA, new therapeutic approaches are emerging. Apart from more selective Janus kinase inhibition, there is a great interest in the granulocyte macrophage-colony stimulating factor pathway, Bruton's tyrosine kinase pathway, phosphoinositide-3-kinase pathway, neural stimulation and dendritic cell-based therapeutics. In this review, we will discuss the therapeutic potential of these novel approaches

Chronic endometritis and infertility — in vitro fertilization outcomes: systematic review and meta-analysis

Background. The relevance of the problem is related to the high prevalence of chronic endometritis (CE); its role in female infertility, implantation failures during assisted reproductive technology procedures, and recurrent miscarriage; as well as the lack of a unified strategy in the diagnosis and treatment of this pathology. The present systematic review with a meta-analysis focuses on evaluating the impact of CE and its therapy on the outcome of in vitro fertilization. In addition, the effect of CE of various severity on the outcomes of assisted reproductive technologies is analyzed. Objective. To analyze the effect of CE of varying severity and its treatment on the outcomes of in vitro fertilization. Methods. Using PubMed, Medline, Scopus, Embase, ELibrary, Cochrane Central Register of Controlled Trials (CENTRAL), WHO International Clinical Trials Registry, and Russian Science Citation Index, a systematic search was conducted for articles published over the past 12 years that met the following criteria: randomized controlled trial examining the effect of CE of varying severity on fertility and ways to treat it. The following indicators were calculated: ongoing pregnancy/live birth, clinical pregnancy, and miscarriage rates. A total of 4145 patients (from ten studies) were included. A meta-analysis was performed using Stata 11.0 software (The Cochrane Collaboration, Oxford, UK). The heterogeneity was considered low at I2 &lt;30%, moderate at 30–50%, and high at &gt;50%. Results. Women with CE exhibited lower ongoing pregnancy/live birth (OR 1.97; p = 0.02) and clinical pregnancy rates (OR 2.28; p = 0.002) as compared to women without it. CE treatment increased the ongoing pregnancy/live birth (OR 5.33; p &lt; 0.0001) and clinical pregnancy rates (OR 3.64; p = 0.0001). In vitro fertilization outcomes were comparable in women treated for CE and women without CE (ongoing pregnancy/live birth rate, clinical pregnancy rate, and miscarriage rate: p = ns). Women with severe CE exhibited lower ongoing pregnancy/live birth (OR 0.43; p = 0.003) and clinical pregnancy rates (OR 0.40; p = 0.0007). Mild CE showed no significant effect on in vitro fertilization outcomes (ongoing pregnancy/ live birth rate, clinical pregnancy rate, and miscarriage rate: p = ns). Conclusion. The conducted meta-analysis showed that CE significantly reduces the ongoing pregnancy/live birth and clinical pregnancy rates in infertile women undergoing in vitro fertilization. Noteworthy is that antimicrobial therapy in such patients improves the results of assisted reproductive technologies, which are comparable to those of patients without CE. The negative impact of this pathology on the implantation capacity of the endometrium is most often observed in the severe form, while its mild form has virtually no effect on the in vitro fertilization outcome

High Tc superconductivity at a critical strain and charge density in diborides

We report variation of lattice structure in diborides (AB2) with different A atoms to identify the special case of MgB2 showing high Tc superconductivity. High purity MgB2 (Tc~39 K) has been prepared by direct reaction of the elements and the lattice parameters are measured by x-ray diffraction determining the strain e of the B-B distance. The results show that the superconductivity in these intermetallics appear near a critical point in a two variables (strain and charge density) phase diagram at (ec, rc).Comment: 10 page
