Top 100 Highly Cited Articles on Rhinoplasty between 2001 and 2020: A Bibliometric and Visualized Analysis.

BACKGROUND: The authors performed a bibliometric and visualized analysis of the top 100 highly cited articles in rhinoplasty published between 2001 and 2020, to provide researchers with the present research status and the potential directions. METHODS: The authors obtained data from the Web of Science Core Collection on April 7, 2021. Quantitative and qualitative analyses were performed using the Web of Science. Collaboration and keyword analyses were performed using VOSviewer software. RESULTS: The top 100 highly cited articles included 86 original research articles and 14 reviews. The average total citations was 77 (range, 50 to 202). The article with 202 citations was published by Toriumi in 2006 and was the most influential reference. The most common level of evidence was level IV ( n = 24). Only five articles had a level of evidence of I. The top 100 articles were published in 24 journals. Plastic and Reconstructive Surgery published 49 articles with 4013 citations. The United States published the most highly cited articles. The University of Texas System published 16 articles with 1166 citations. R. J. Rohrich published 14 articles with 1025 total citations. "Cleft lip and palate," "FACE-Q," "Functional Rhinoplasty Outcome Inventory 17," "NOSE scale" (Nasal Obstruction Symptom Evaluation scale), "quality-of-life," "questionnaire," and "RHINO scale" (Rhinoplasty Health Inventory and Nasal Outcomes scale) were important keywords. CONCLUSIONS: Plastic and Reconstructive Surgery was the most influential journal, most research was reported from the United States, and the University of Texas System published the most highly cited article. R. J. Rohrich, R. K. Daniel, and B. Guyuron were the most prolific and influential authors. Global cooperation in rhinoplasty requires further strengthening.

Quantitative (1)H and hyperpolarized (3)He magnetic resonance imaging: comparison in chronic obstructive pulmonary disease and healthy never-smokers.

OBJECTIVE: The aim of this study was to quantitatively evaluate the relationship between short echo time pulmonary (1)H magnetic resonance imaging (MRI) signal intensity (SI) and (3)He MRI apparent diffusion coefficients (ADC), high-resolution computed tomography (CT) measurements of emphysema, and pulmonary function measurements. MATERIALS AND METHODS: Nine healthy never-smokers and 11 COPD subjects underwent same-day plethysmography, spirometry, short echo time ((TE)=1.2ms) (1)H and diffusion-weighted hyperpolarized (3)He MRI (b=1.6s/cm(2)) at 3.0T. In addition, for COPD subjects only, CT densitometry was also performed. RESULTS: Mean (1)H SI was significantly greater for never-smokers (12.1 ± 1.1 arbitrary units (AU)) compared to COPD subjects (10.9 ± 1.3 AU, p=0.04). The (1)H SI AP-gradient was also significantly greater for never-smokers (0.40 AU/cm, R(2)=0.94) compared to COPD subjects (0.29 AU/cm, R(2)=0.968, p=0.05). There was a significant correlation between (1)H SI and (3)He ADC (r=-0.58, p=0.008) and significant correlations between (1)H MR SI and CT measurements of emphysema (RA950, r=-0.69, p=0.02 and HU15, r=0.66, p=0.03). CONCLUSIONS: The significant and moderately strong relationship between (1)H SI and (3)He ADC, as well as between (1)H SI and CT measurements of emphysema suggests that these imaging methods and measurements may be quantifying similar tissue changes in COPD and that pulmonary (1)H SI may be used to monitor emphysema as a complement to CT and noble gas MRI.

Emissions of EC, OC, and PAHs from cottonseed oil biodiesel in a heavy-duty diesel engine.

Biodiesel fuels, made from renewable resources, have emerged as viable alternatives to conventional diesel fuel, but their impact on emissions is not fully understood. This study examines elemental carbon (EC), organic carbon (OC), and polycyclic aromatic hydrocarbons (PAHs) emissions from cottonseed oil biodiesel (CSO-B100). Relative to normal diesel fuel, CSO-B100 reduced EC emissions by 64% (±16%). The bulk of EC emitted from CSO-B100 was in the fine particle mode (<1.4 µm), which is similar to normal diesel. OC was found in all size ranges, whereas emissions of OC(1.4-2.5) were proportionately higher in OC(2.5) from CSO-B100 than from diesel. The CSO-B100 emission factors derived from this study are significantly lower, even without aftertreatment, than the China-4 emission standards established in Beijing and Euro-IV diesel engine standards. The toxic equivalency factors (TEFs) for CSO-B100 was half the TEFs of diesel, which suggests that PAHs emitted from CSO-B100 may be less toxic.

An essential role for CCL3 in the development of collagen antibody-induced arthritis.

CCL3 is a C-C family chemokine detected at high levels in the synovial tissue and fluids of rheumatoid arthritis (RA) patients. CCL3 binds to the chemokine receptors CCR1 and CCR5, which are expressed by inflammatory leukocytes such as macrophages and T cells present in the affected joints of RA patients. The present study was undertaken to investigate whether absence of CCL3 prevented development of inflammation and joint destruction in anti-type II collagen monoclonal antibody (anti-CII mAb)-induced arthritis. "CCL3 null mice were different from wild-type control mice in terms of body weight loss". In addition, CCL3 null mice exhibited milder clinical and histopathological scores following administration of anti-CII mAb and endotoxin. Moreover, the release of TNF in response to systemic administration of endotoxin was not affected in CCL3 null mice compared to wild-type mice, indicating that the phenotype was not attributable to a defect in endotoxin response. These results indicate that CCL3 plays an essential role in the development of inflammation and joint destruction induced by anti-CII mAb.
