Circular RNAs (circRNAs) may act as biomarkers of coronary artery disease (CAD). However, the relationship between expression characteristics of circRNAs and coronary atherosclerosis has not been fully explored. The aim of this study was to determine and characterize the circRNAs from human coronary artery.

The coronary artery segments were obtained from an 81-year-old male patient with sudden death of myocardial infarction at autopsy. The coronary stenosis and atherosclerosis were evaluated by hematoxylin and eosin (H&E) staining, and the circRNAs expression profile was characterized by RNA sequencing (RNA-seq). The differentially expressed circRNAs were validated by qRT-PCR.

The analysis of H&E staining indicated that coronary atherosclerosis grade and extent in the LM was more serious than that in other coronary arteries. Remodelin Twenty-seven circRNAs were selected for expression validation in coronary artery. CircRNAs corresponding cyclization sites of 3 circRNAs (hsa_circ_0016868, hsa_circ_0001364, hsa_circ_0006731) have been verified by Sanger sequencing.

The 3 circRNAs are suggested to play a pathological role underlying the coronary arteries atherosclerosis and may serve as a valuable resource as diagnostic or therapeutic targets against CAD.

The structure-activity relationship studies (SARs) indicated that the replacement of hydroxyethyl and benzhydryl piperazine groups could improve efficacy. Compounds 12r and 14a-14c exhibited a higher inhibitory effect on LPS-induced nitric oxide (NO) production in RAW264.7 macrophages than Aloe-emodin did. Among them, 12r showed the most potent inhibition with an IC50 value of 5.66 ± 0.47 μM. Further toxicity and pharmacokinetic studies were carried out and 12r was found to be the most active structure with low toxicity risk and good metabolic properties. It could also decrease the levels of IL-1β, TNF-α, PGE2 and inhibit the activation of nuclear factor-κB signalling pathway. Importantly, 12r showed oral bioavailability of up to 55.16% and attenuated the inflammatory symptoms in an ulcerative colitis mouse model in vivo. These results indicate that 12r is suitable for development as an anti-inflammatory agent.

The implications of oral rehabilitation after tooth loss require further investigation.

To conduct a pilot study to investigate (a) changes in masticatory performance with progressive oral implant rehabilitation (POR); (b) association between POR and neurocognitive function using functional magnetic resonance imaging (fMRI); and (c) oral health-related quality of life (OHQoL) outcomes.

Four completely edentulous patients (mean age 73±1.4years) participated. Each received new complete removable dental prostheses (RDPs) transitioned to mandibular two implant-retained RDPs (IR-RDP). Assessments were performed at 4 time points for neurocognitive skills, fMRI with functional tasks (jaw clenching, working memory and sustained attention, inhibition), masticatory performance with colour-changing gum and OHQoL. Assessments were performed with new complete RDPs (T0 as baseline data) and IR-RDPs at 1week (T1), 6weeks (T2) and 12months (T3) post-insertion. Data analyses were based on intra-patient and inter-patientls or greater after 6 weeks. These pilot data suggest both behavioural and neural associations between POR and cognition; however, larger study numbers are required.

The purpose of this study is to analyze and classify morphological features of the nasolacrimal duct (NLD) through 3D reconstruction to help understand the causes and treatment of NLD obstruction.

In this study, we included 63 males and 55 females who underwent autopsy without NLD obstruction with ages ranging from 20 to 78 years. The NLD was defined from the lacrimal fossa to the opening of the BNLD to the inferior meatus, and all continuous CT images showing the NLD were selected. Segmentation was performed semi-automatically, and the reconstruction and measurement of NLD was performed using the Mimics program.

Overall NLD length, bony nasolacrimal duct (BNLD) length, anteroposterior and transverse diameters at the entrance to the BNLD, anteroposterior and transverse smallest diameters of the BNLD, BNLD volume, and lacrimal sac BNLD angle were significantly higher in males than females (p < .05). BNLD direction in the coronal plane was slightly more likely to be inward. The most common type in both sexes was cylinder type (42.0%), males were more likely to have lower-thicker types (34.1%), and females more likely to have upper-thicker types (22.7%).

There were sex differences in NLD measurements, and females had significantly smaller NLDs. These results may partially explain the increased prevalence of primary acquired NLD obstruction in females. The BNLD tends toward the midline, and inclines posteriorly.

Static respirometry is used to calculate the standard metabolic rate (SMR) of fish, and when combined with exhaustive chase protocols it can be used to measure maximum metabolic rate (MMR) and aerobic scope (AS) as well. While these methods have been tested in comparison to swim tunnels and chambers with circular currents, they have not been tested in comparison with a no-chase control. We used a repeated-measures design to compare estimates of SMR, MMR and AS in European perch Perca fluviatilis following three protocols (a) a no-chase control; (b) a 3-min exhaustive chase; and (c) a 3-min exhaustive chase followed by 1-min air exposure. We found that, contrary to expectations, exhaustive chase protocols underestimate MMR and AS at 18°C, compared to the no-chase control. This suggests that metabolic rates of other species with similar locomotorty modes or lifestyles could be similarly underestimated using chase protocols.
