From the literature the analytical calculation of local power and astigmatism of a wavefront after refraction and propagation is well known; it is, e.g., performed by the Coddington equation for refraction and the classical vertex correction formula for propagation. Recently the authors succeeded in extending the Coddington equation to higher order aberrations (HOA). However, equivalent analyti...

In order to determine anti-adipogenic effect, this study investigated 1β-hydroxy-2-oxopomolic acid (HOA) isolated from Agrimonia pilosa inhibits adipocyte differentiation and expression of adipogenic marker genes, such as peroxisome proliferator activated receptor γ (PPARγ), CCAAT-enhancer-binding protein α (C/EBPα), glucose transporter 4 (GLUT4), adiponectin, adipocyte fatty acid-binding prote...

purpose: to compare visual outcomes and changes in high-order aberrations (hoas) following conventional versus customized photorefractive keratectomy (prk). methods: in this clinical trial, 58 eyes of 29 patients underwent myopic prk using the technolas 217z excimer machine. after comprehensive evaluation for refractive surgery, one eye of each participant randomly received conventional ablatio...

OBJECTIVE To use novel methods to examine age associations across an integrated brain network in healthy older adults (HOA) and individuals with late-life depression (LLD). Graph theory metrics describe the organizational configuration of both the global network and specified brain regions. METHODS Cross-sectional data were acquired. Graph theory was used to explore diffusion tensor imaging-d...

OBJECTIVE The SF-SACRAH was developed to assess the involvement of the hand in rheumatoid arthritis (RA) and hand osteoarthritis (HOA) patients in daily clinical routines. In this pilot study, its sensitivity to change will be assessed longitudinally, and preliminary thresholds for patient relevant changes are derived. METHODS Ninety-nine outpatients suffering from HOA (n = 55) or RA (n = 44)...

Hypertrophic osteoarthropathy (HOA) is a condition characterized by periosteal reaction of tubular long bones and characteristic bulbous deformity of the digital tips with synovial effusion. It is usually encountered in conjunction with diseases involving the lungs, mediastinum, heart, pleura and gastrointestinal tract. The occurrence of HOA as a paraneoplastic manifestation in nasopharyngeal c...

PURPOSE To evaluate the changes and predictability of higher order aberrations (HOAs) after personalized laser in situ keratomileusis (LASIK) and personalized photorefractive keratectomy (PRK) for simple myopia and compound myopic astigmatism. METHODS In this prospective cross-sectional study, 100 eyes were included. A total of 50 eyes underwent personalized LASIK and 50 eyes underwent person...

Hypertrophic osteoarthropathy (HOA) is a group of syndromes characterized by clubbing, polyarthritis, and periosteal reaction. It is usually secondary to thoracic tumors and is extremely rare in children, therefore is easily to be misdiagnosed and delayed. In this study, we present an 11-year-old boy hospitalized because of joint swelling and pain accompanied by obvious clubbing, and was finall...

BACKGROUND Dissatisfaction with hand appearance is frequently the presenting complaint of patients with hand osteoarthritis (HOA), yet no tool exists for its measurement and few studies have examined aesthetic discomfort. OBJECTIVES The aims of this study were to measure the extent and to explore the associations of aesthetic concerns in HOA. METHODS 172 patients with HOA were assessed with...

Hand osteoarthritis (HOA) is a prevalent condition for which treatments are based on analgesia and physical therapies. Our primary objective was to evaluate pain perception in participants with HOA by assessing the characteristics of nodal involvement, pain threshold in each hand joint, and radiological severity. We hypothesised that inflammation in hand osteoarthritis joints enhances sensitivi...
