Circular RNA hsa_circ_0000117 is reportedly increased in Gastric cancer (GC), however, its role is unexplored. Hsa_circ_0000117 expression and function in GC was investigated using standard cell phenotypic and expression assays. Pull-down and luciferase reporter assays also elucidated hsa_circ_0000117 mechanisms. In the present study, we observed increased hsa_circ_0000117 and signal transducer and activator of transcription 3 (STAT3) expression, while microRNA-337-3p (miR-337-3p) was decreased in GC cells. Depleted hsa_circ_0000117 decreased GC proliferation and invasion. find more Hsa_circ_0000117 was also identified as a miR-337-3p sponge. Also, STAT3 was identified as a miR-337-3p target. Similarly, rescue assays indicated STAT3 overexpression (or miR-337-3p inhibition) reversed hsa_circ_0000117 effects in GC progression. Thus, our data suggested hsa_circ_0000117 exhibited oncogene properties in combination with the hsa_circ_0000117/miR-337-3p/STAT3 axis in GC, potentially providing a new therapeutic target for GC.Abbreviations GC gastric cancer; STAT3 Signal transducer and activator of transcription 3; circRNA Circular RNA; miRNA microRNA; DMEM Dulbecco's modified Eagle's medium; FBS fetal bovine serum; PVDF polyvinylidene fluoride; CCK-8 Cell counting kit-8; qRT-PCR Quantitative real-time PCR; SDS-PAGE sodium dodecyl sulfate polyacrylamide gel electrophoresis; TNM TNM Classification of Malignant Tumors; mTOR mechanistic target of rapamycin; ANOVA one-way analysis of variance.A novel Schiff base was synthesized by the condensation of imidazole-2-carboxaldehyde with l-histidine in an equimolar ratio. The prepared Schiff base was characterized by elemental analysis and spectral characterization techniques. It was then complexed with a series of 3-d metal(II) ions like manganese, iron, cobalt, nickel, copper and zinc. The coordination properties, nature of bonding and stability of the complexes were deduced from elemental analysis, IR, UV-vis, 1H NMR, mass, electronic spectra, magnetic, conductivity and thermogravimetric analysis. IR studies support the tridentate behaviour of Schiff base as well as its coordination to the central metal ion through an azomethine nitrogen, deprotonated carboxylic oxygen and imidazole ring nitrogen atoms of histidine. The electronic spectra and magnetic moment data demonstrate that the complexes have an octahedral geometry, except zinc complex, which has a tetrahedral geometry. In vitro antimicrobial activity of the synthesized compounds has been shown to exhibit excellent antibacterial and antifungal activities. The antibacterial property of the prepared Schiff base was further confirmed by conducting a docking study of target proteins involved in the antibacterial mechanism.Communicated by Ramaswamy H. Sarma.Methylglyoxal (MGO) is considered responsible for the detrimental effects of high blood glucose. MGO is produced as a by-product of the glycolysis pathway. While the glyoxalase system removes it, the system fails in people with diabetes. MGO concentration is detected as elevated in these patients. Endoplasmic reticulum (ER) stress may play a role in atherosclerosis progression and vascular diseases. If ER stress persists, it may result in apoptosis of the cell. As a result, stabilized plaque structure by these cells may be ruptured and cause a stroke. This study aimed to investigate whether MGO can induce ER stress and apoptosis in vascular smooth muscle cells (VSMCs). Also, the effects of aminoguanidine hydrochloride (AGH), 4-phenylbutyric acid (4-PBA), and tauroursodeoxycholic acid (TUDCA) were scrutinized to relieve ER stress. VSMCs were isolated from rat aorta and cultured primary. PERK phosphorylation, IRE1α, ATF6, BiP (Grp78), and CHOP expressions were detected by the western blot technique. A caspase-3 assay kit measured the apoptosis. MGO could stimulate the main three ER stress pathways, PERK phosphorylation, IRE1α, and ATF6 expressions in a time- and concentration-dependent manner. Furthermore, AGH, 4-PBA, and TUDCA alleviated MGO-induced ER stress. However, we detected neither an increase in CHOP expression nor apoptosis in VSMCs. This study shows that MGO induces ER stress even at low concentrations in VSMCs. The impaired glyoxalase system may cause MGO accumulation and result in persisted ER stress. Supposing that ER stress is not mitigated, this table might be finalized in cell apoptosis, plaque rupture, and stroke.
To determine the anterior Bolton ratio for a Finnish adult population and to investigate its associations with overjet.
This study is part of the Northern Finland Birth Cohort 1966. Clinical oral investigations, including three-dimensional intraoral scanning and registration of occlusion, were performed in connection with the 46-year follow-up for 1,961 subjects. Subjects with normal occlusion (
= 149), extreme overjet ≥ 8 mm (
= 49), large overjet 6-7 mm (
= 86), and negative overjet (
= 16) and no orthodontic treatment history were selected for further analysis. The mesiodistal widths were measured from canine to canine to evaluate the anterior Bolton ratio.
A mean anterior Bolton ratio of 78.6 (SD 3.1) was found for the normal occlusion group. Subjects with extreme overjet had smaller Bolton ratios compared to the normal occlusion group and the negative overjet group (
= .005,
= .019, respectively). Overjet deviations were associated with upper canine and incisor widths.
The mean anterior Bolton ratio in subjects with normal occlusion was larger compared to the original Bolton ratio. Tooth size discrepancy was associated with extreme and negative overjet at population level.

The purpose of this study is to describe the post-discharge needs of children and adolescents when transitioning home after an inpatient comprehensive rehabilitation stay following an acute neurological injury and to evaluate if trends in those needs changed with implementation of a discharge nurse intervention.
Retrospective medical record review was conducted 1-year prior (T1) and 1-year after (T2) a discharge nurse intervention.
Medical charts of 80 pediatric patients with acute neurological injury (T1=39; T2=41) were reviewed. Post-discharge communication from the 8-week post-discharge period was reviewed to identify and categorize care coordination needs, using 18 pre-defined care coordination categories. T1 and T2 findings were compared using two sample proportion z-test.
Patients discharged following inpatient rehabilitation for acute neurological injury have unmet care coordination needs. The proportion of unmet needs decreased significantly for 10/18 care coordination categories after implementation of the discharge nurse intervention.
Data from this study support proactive care coordination by inpatient rehabilitation nurses to reduce unmet post-discharge care coordination needs and provides preliminary evidence that the role of a discharge nurse may have a positive impact on the transition from inpatient rehabilitation to home.

Worldwide, there is a global progressive rise of chronic kidney disease. In parallel, children born after intra-uterine growth retardation are surviving to adult-life and beyond. This study describes the association of birthweight with and estimated glomerular filtration rate (eGFR).
Australian Diabetes, Obesity and Lifestyle (AusDiab) study participants were asked to complete a birthweight questionnaire. The associations between birthweight and eGFR were determined.
A total of 4502 reported information related to their birthweight, with the other responders did not provide a value. The birthweight of the participants ranged from 0.4 to 7.0 kg with a mean-(SD) of 3.37 (0.7) kg. The mean (95%CI) birthweight was lower for females, 3.28 (0.6) kg, when compared to males, 3.5 (0.7) kg. Eight percent had a birthweight less than 2.5 kg. The eGFR was strongly and positively associated with birthweight, with people in the lowest sex-specific birthweight-quintiles having the lowest mean eGFR. This relationship peower birthweights coexist with recently improved infant and adult survivals, the overall impact of this phenomenon on the population health profile could be more substantial.This study assessed the performance of SD Bioline MPT64 immunochromatographic test for the identification of Mycobacterium tuberculosis complex (MTBC) in Nigeria.A total of 157 mycobacterial isolates, comprising 120 (76.4%) MTBC (M. tuberculosis, 112; M. africanum, 5; M. bovis, 3) and 37 (23.6%) non-tuberculous mycobacteria (NTM) isolates from patients attending six DOTS centers in Lagos between June 2012 and July 2014 were analyzed. All the isolates were grown on Bactec MGIT960 liquid media and identified in parallel by the conventional method and MPT64 immunochromatographic test. Discrepant results were resolved using the line probe assay.The comorbid disease rates for HIV and type 2 diabetes were 20.9% and 8.2%, respectively. Compared to the conventional method, SD Bioline MPT64 identified 117 MTBC isolates correctly, producing a sensitivity of 97.5% (95% CI, 92.9-99.2) at a shorter growing median time of 11 days compared to 26 days by the conventional method. The three undetected MTBC were confirmed by the line probe assay to be M. tuberculosis strains. The test also identified all the NTM correctly producing a specificity of 100% (95% CI, 90.7-100).This study supports the integration of SD Bioline TB MPT64 antigen test into diagnostic workflow for rapid MTBC case identification in Nigeria.Hypoxia inducible factor-1 is a heterodimeric transcription factor that regulates cellular responses to hypoxia and is involved in tumor progression and resistance to chemotherapy. Dimerization between HIF-1α and β subunits has been recognized crucial for DNA binding and transcriptional activity of HIF-1. Therefore, inhibitors of α and β dimerization subunits of HIF-1 may potentially evade HIF-1-mediated chemotherapy resistance. In the current study, ligand-based pharmacophore model was developed to determine 3 D binding features of HIF-1 inhibitors. The selected pharmacophore model comprises of one hydrogen bond donor, one hydrogen bond acceptor and one hydrophobic feature. The selected model was used for virtual screening of publically available data base by ChemBridge Corporation. Overall, six potential hits against HIF-1α and β dimerization have been identified. These include, Hit 1 (4-(4-chlorophenyl)-2,6-dimethyl-3,5-pyridinedicarboxylic acid), 3 (2-[2-(2-hydroxybenzoyl)carbonohydrazonoyl]benzoic acid) and 5 (3-(4-methoxyphenyl)-2,4-quinolinedicarboxylic acid) nicotonic acid derivatives, Hit 2 (3-[(1-adamantylamino)sulfonyl]benzoic acid), 4 (5-[(2-fluorophenyl)amino]sulfonyl-2-methylbenzoic acid), and 6 (4-([2-(trifluoromethyl)phenyl]sulfonylamino)benzoic acid) sulfonamide derivatives. Additionally, adamantyl moiety of compound 2 shows interactions with the experimentally known hydrophobic amino acid residues (V336, C334, E245) of HIF-1α and β dimerization site. The identified hits showed lower to higher µM biological activity (IC50) values and thus, after further structure optimization may serve as potential inhibitor of HIF-1 dimerization in cancer chemotherapy.Communicated by Ramaswamy H.
