Quantifying and Clustering Texture Traits in Flowers of Genus Sinningia
( Tzu-ting Hung ),( Hao-chun Hsu ),( Yan-fu Kuo ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1
The flowers of genus Sinningia has a high degree of diversity in stripe and spot patterns. Delimiting these pattern as textural traits usually rely on horticulturalists’ judgment. However, the judgment by intuitive observation is subjective. This study aimed to quantify the stripe and spot pattern of genus Sinningia flowers automatically using machine vision and to cluster the textural traits using machine learning. The image of ventral petal was acquired using flatbed scanners. Two regions of interest (ROI), lobe region and tube region, were identified and were used for the feature quantification. The features of stripe and spot patterns were then quantified from the ROI using Gabor and Laplacian of Gaussian filters, respectively. The k-means clustering algorithm was next applied to the feature of patterns. The clusters were significantly associated with the textural traits.

Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic mucosal inflammation of the colon, and the prevalence and incidence of UC have been steadily increasing in Taiwan. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of UC taking into account currently available evidence and the expert opinion of the committee. Accurate diagnosis of UC requires thorough clinical, endoscopic, and histological assessment and careful exclusion of differential diagnoses, particularly infectious colitis. The goals of UC therapy are to induce and maintain remission, reduce the risk of complications, and improve quality of life. As outlined in the recommended treatment algorithm, choice of treatment is dictated by severity, extent, and course of disease. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to immunosuppressive treatment, especially with steroids and biologic agents, and should be regularly monitored for reactivation of latent infection. These consensus statements are also based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of UC in Taiwan.

Crohn`s disease (CD) is a chronic relapsing and remitting inflammatory disease of the gastrointestinal tract. CD is rare in Taiwan and other Asian countries, but its prevalence and incidence have been steadily increasing. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of CD taking into account currently available evidence and the expert opinion of the committee. Thorough clinical, endoscopic, and histological assessments are required for accurate diagnosis of CD. Computed tomography and magnetic resonance imaging are complementary to endoscopic evaluation for disease staging and detecting complications. The goals of CD management are to induce and maintain remission, reduce the risk of complications, and improve quality of life. Corticosteroids are the mainstay for inducing re-mission. Immunomodulating and biologic therapies should be used to maintain remission. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to treatment and receive regular surveillance for cancer. These consensus statements are based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of patients with CD in Taiwan.

Evidence indicates that indirect inhibitory regulation of glutamatergic transmission, via reducing glutamate release, may induce neuroprotection. The present work was designed to examine whether allicin, a major component of garlic with neuroprotective effects, affected the release of glutamate evoked by 4-aminopyridine in rat cerebrocortical nerve terminals (synaptosomes). Allicin caused a potent inhibition on the release of glutamate evoked by 4-aminopyridine, and this inhibitory effect was abolished in the presence of Ca2+-free medium and vesicular transporter inhibitor. Allicin decreased the 4-aminopyridine-evoked elevation of intrasynaptosomal Ca2+ levels, but had no effect on the synaptosomal plasma membrane potential. The allicin-mediated inhibition of glutamate release was prevented by the N- and P/Q-type channel blocker and the protein kinase C (PKC) inhibitor, but was not affected by the intracellular Ca2+-release inhibitors, mitogen-activated protein kinase inhibitor, and protein kinase A inhibitor. Western blotting data also showed that allicin significantly reduced the phosphorylation of PKC. Together, these data indicate that in rat cerebrocortical nerve terminals, allicin depresses glutamate release and appears to decrease N- and P/Q-type Ca2+ channel and PKC activity.
