Accurate determination of the biomedical properties of connective tissue such as tendons and ligaments is dependent on the accurate measurement of their cross-sectional area (CSA). To date, techniques for determining cross-sectional areas of ligaments and tendons have been less than ideal due to their complex geometries and their deformations under external load. A novel non-destructive technique has been developed for determining the cross-sectional area of tendon by locating the tendon rupture, in which aqueous rapid curing alginate dental molding materials, digital photography and computerized image analysis are utilized. This technique marks tendons and alginate molds at 1 cm interval and then tendons are taken out for tensile test. Real-time video is recorded to locate the position of tendon rupture. The corresponding alginate slice is found and then analysis through computer image processing software to obtain a more accurate CSA at tendon rupture, which can be used to calculate the stress and young's modulus of tendon. The accuracy of this technique has been investigated and comparisons have been made with the alginate un-localization molding technique and ellipse estimation technique. Results show this technique can provide accurate CSA values (within 2%) and great reproducibility (coefficient of variation = 0.8%). The technique is non-destructive, can obtain morphological information of soft tissue and can detect cavities.
Adenoma detection rate (ADR) is an important quality indicator of colonoscopy. High-definition (HD) colonoscopy has been reported to increase ADR compared to standard-definition (SD) colonoscopy. Although there are few reports comparing the latest generation and the previous generation of HD colonoscopy equipment, there are reports that the latest generation colonoscopy equipment improves ADR. ML-SI3 chemical structure However, there are no reports on the impact of the latest generation HD colonoscopy on the ADR of trainee endoscopists.
The aim of this study was to investigate whether the latest generation HD colonoscopy increases the ADR of trainee endoscopists compared with the previous generation HD colonoscopy.
We conducted a retrospective review of medical records of patients aged 40-79years old, who underwent screening or surveillance colonoscopy performed by nine gastroenterology fellows at Dong-A University Hospital from March 2019 to February 2020. We calculated the overall ratios of the ADR the ADRs of the group using oved PDR and ADR by trainee endoscopists. These findings suggest that latest generation, higher-resolution colonoscopy equipment can improve the quality of colonoscopy for less experienced endoscopists.

We evaluated the probiotic properties of four riboflavin-producing strains of Lactobacillus plantarum (BBC33, BBC32A, BIF43, and BBC32B) by using in vitro assessment and carried out multivariate principal component analysis (PCA) to select the best strain. Safety, antioxidant, and exopolysaccharide-producing properties were also studied. Lact. plantarum BBC33 showed better probiotic potential, followed by strain BIF43. Lact. plantarum BBC32A degraded mucin and excluded as a potential probiotic candidate. Lact. plantarum BIF43, BBC33, and BBC32A tolerated simulated gastrointestinal conditions and their overnight cell-free culture supernatants (CFSs, pH 4.0-4.3) inhibited the growth of Escherichia coli AF10, Salmonella Typhi MTCC98, Bacillus cereus NCDC250, and Pseudomonas aeruginosa NCDC105. Lact. plantarum BIF43 and BBC33 did not degrade mucin, adhered to human epithelial colorectal adenocarcinoma Caco-2 cells (22-25%), and aggregated with indicators (30-50%). Moreover, both were non-hemolytic and sensitive to most antibiotics tested. Of the two selected strains, BIF43 showed better exopolysaccharides (EPS) producing phenotype. The CFSs of all strains showed high (85-93%) 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity. PCA confirmed the results obtained from in vitro probiotic experiments and supported the selection of Lact. plantarum BIF33 and BBC43, as potential probiotics.Poor physical function and body composition my partly predict the risk of falls leading to fracture regardless of bone mineral density.
To examine the relationship between body composition, physical function, and other markers of health with hip fractures in older community-dwelling Icelandic adults.
A prospective cohort of 4782 older adults from the AGES-Reykjavik study. Baseline recruitment took place between 2002 and 2006, and information on hip fractures occurring through 2012 was extracted from clinical records. Using multivariate regression analyses, baseline measures of bone health, physical function, and body composition were compared between those who later experienced hip fractures and to those who did not. Associations with the risk of fractures were quantified using Cox regression.
Mean age was 76.3 years at baseline. After adjustment for age, regression showed that male hip fracture cases compared with non-cases had (mean (95% confidence interval)) significantly lower thigh muscle cross-secte and BMD, older adults who later experienced a hip fracture had poorer baseline measures of physical function and/or body composition, which may at least partly contribute to the risk of falls leading to fracture.Among 4238 cancer and 16,418 cancer-free individuals with incident major non-traumatic fractures (hip, clinical vertebral, forearm, humerus), post-fracture osteoporosis care was equally poor for both groups, whether assessed from bone mineral density (BMD) testing, initiation of osteoporosis therapy or either intervention (BMD testing and/or osteoporosis therapy).
Most individuals sustaining a fracture do not undergo evaluation and/or treatment for osteoporosis. Cancer survivors are at increased risk for osteoporosis and fracture. Whether cancer survivors experience a similar post-fracture "care gap" is unclear. Using population-based databases, we assessed whether cancer patients are evaluated and/or treated for osteoporosis after a major fracture.
From the Manitoba Cancer Registry, we identified cancer cases (first cancer diagnosis between 1987 and 2013) and cancer-free controls with incident major non-traumatic fractures (from provincial physician billing claims and hospitalization databases). The outcomes were performance of BMD testing (from the BMD Registry), initiation of osteoporosis therapy (from drug dispensation database) or either intervention (BMD testing and/or osteoporosis therapy) in the 12 months post-fracture.
