Growth Regulators Prolong Bract Longevity of Potted Bougainvillea
Fang-Yin Liu,Yu-Sen Chang 한국원예학회 2011 원예과학기술지 Vol.29 No.4
When bougainvilleas are subjected to indoor low-light conditions, flower bracts regularly abscise. This study elucidates the effects of plant growth regulators on bract longevity of potted bougainvillea. Potted ‘Taipei Red’ bougainvillea in four different bract development stages were treated with 1-MCP (1-methylcyclopropene), NAA (1-naphthaleneacetic acid), SNA (sodium salt of naphthaleneacetic acid), IBA (indolebutyric acid), BA (6-benzylaminopurine), KH₂PO₄ (potassium dihydrogen phosphate), Put (diamine putrescine), SA (salicylic acid), or STS (silver thiosulfate) and were moved to indoor low-light conditions after treatments. Experimental results indicate that 1-MCP, NAA, SNA, BA, Put, and SA prolonged bract longevity, and this effect increased as bract stage increased. The effect of STS was significant in early bract stages and decreased as bract stages increased. Additionally, 1-MCP, NAA, SNA, BA, Put, SA, and STS treatment significantly reduced endogenous ACC (1-aminocyclopropene-1-carboxylate) content and ACC oxidase activity, suggesting that the inhibition of ethylene production was achieved via physiological metabolism. However, treatment with IBA or KH₂PO₄ had no effect on the bract longevity at any stage. In the combined chemical treatments, NAA + STS or NAA + SA were effectively for prolonging bract longevity and contained less protein or chlorophyll degradation, decrease ACC oxidase or ethylene production than the control. In conclusion, we propose that combined chemical treatment significantly prolonged the bract longevity and more effectively than single chemical treatment at any stage.

Air Embolism during Upper Endoscopy: A Case Report
Yin Fang,Junbei Wu,Feng Wang,Lihong Cheng,Yunhong Lu,Xiaofei Cao 대한소화기내시경학회 2019 Clinical Endoscopy Vol.52 No.4
Air embolism is a rare complication of upper endoscopy and potentially causes life-threatening events. A 67-year-old man with ahistory of surgery of cardiac carcinoma and pancreatic neuroendocrine tumor underwent painless upper endoscopy because oftarry stools. During the procedure, air embolism developed, which caused decreased pulse oxygen saturation and delayed sedationrecovery. He recovered with some weakness of the left upper limb in the intensive care unit without hyperbaric oxygen therapy. Theetiology, clinical manifestations, and treatments of air embolism are discussed based on the literature reports. Although air embolism isuncommon in endoscopic examinations, the patients’ outcomes could be improved if clinicians are alert to this potential complication,and promptly start proper diagnostic and therapeutic measures.

Two experiments were conducted to determine the additivity of apparent or true digestibility of phosphorus (P) in soybean meal (SBM), peas, faba beans, corn, oats, broken rice meal, rough rice meal, buckwheat, and sorghum for growing pigs. Chromic oxide (0.3%) was used as a digestion marker in both experiments. Each experiment lasted for 12 d, which consisted of a 7-d dietary adaptation period followed by a 5-d fecal collection period. Experiment 1 involved 6 diets: the SBM-based control diet; 4 diets with corn, oats, rough rice meal and broken rice meal substituted for SBM; and an additional diet with a representative mixture of the 5 ingredients. In Experiment 2, 6 diets were prepared similarly, except that the tested ingredients besides SBM were faba beans, peas, buckwheat, and sorghum. In each experiment, six barrows with an initial average individual BW of 20.5 kg were fed one of the six diets according to a $6{\times}6$ Latin square design. The apparent and true P digestibility values for the nine tested ingredients were determined by the substitution method. There were no differences (p>0.05) between the determined and the predicted true P digestibility values for the mixture of ingredients in Experiments 1 and 2. However, the determined and the predicted apparent P digestibility values for the mixture of ingredients differed (p = 0.059) in Experiment 1, but not in Experiment 2. These results indicate that true P digestibility values are additive in ingredients containing low levels of phytate phosphorus and anti-nutritional factors, whereas the apparent P digestibility values are not always additive in single feed ingredients for growing pigs.

Tumor suppressor gene O<sup>6</sup>-methylguanine-DNA methyltransferase (MGMT) promoter methylation has been reported in melanoma. However, the clinical and prognostic significance of MGMT promoter methylation in patients with melanoma remained to be determined. A systematic search was performed to identify eligible papers published. The overall odds ratios (ORs) or hazard ratios and their 95% confidence intervals were calculated. Final 12 eligible publications involving Caucasian population were performed in this study, including 1,071 metastatic melanoma patients, 154 primary melanoma patients, and 211 normal controls. MGMT promoter methylation was significantly higher in primary or metastatic melanoma than in normal controls (p<0.05). No difference of MGMT promoter methylation was found in primary and metastatic melanoma (p=0.432). When metastatic melanoma was compared to normal controls, subgroup analysis showed the correlation between MGMT promoter methylation and different sample materials (tissue: OR=7.01, p<0.001 and blood: OR=12.04, p=0.005). MGMT promoter methylation was not associated with response to drug therapy and the prognosis in overall survival and progression-free survival for multivariate analysis. Our results show that MGMT promoter methylation may be correlated with the increased risk of primary or metastatic melanoma. Based on blood samples, MGMT promoter methylation may become a noninvasive biomarker for the detection of metastatic melanoma. Further additional clinical studies are necessary.

Effects of Temperature and Ethylene Response Inhibitors on Growth and Flowering of Passion Fruit
Fang-Yin Liu,Yung-Liang Peng,Yu-Sen Chang 한국원예학회 2015 원예과학기술지 Vol.33 No.3
This study examined the effects of different day/night temperature regimes or silver ion on growth and flowering of passion fruit ‘Tai-nung No.1’. Low temperature treatment (20/15℃) caused passion fruit cultivar ‘Tai-nung No.1’ to fail to flower. Flowering induction occurred within a temperature range of 20-30℃, with no significant difference in the days to first flower bud and the total number of flower buds between plants grown at 30/25℃ and 25/20℃. However, plants grown at 30/25℃ exhibited their first flower buds set on the higher nodes and had higher abortion rates of flower buds than those at 25/20℃. Plants grown at 30/25℃ had the most rapid growth and the shortest plastochron. We also evaluated the effect of the ethylene response inhibitors silver nitrate (AgNO₃) and silver thiosulfate (STS) on growth and flowering of potted passion fruit ‘Tai-nung No.1’, when they were exposed to low temperature conditions (20/15℃) following chemical treatments (AgNO₃ or STS, at 0.5 or 1.0 mM). AgNO₃ and STS treatments induced flower formation and initial flower bud formation within approximately two weeks at 20/15℃ whereas non-treated control plants exhibited no flower formation. ACC content and activity of ACC oxidase in the leaves of passion fruit ‘Tai-nung No.1’exposed to low temperature conditions (20/15℃) were significantly inhibited by the ethylene inhibitor treatments. These results indicate that ethylene, which is produced under low temperature conditions, plays an important role in inhibiting flower formation in passion fruit.
