1Disassembly of the fruit cell wall by the ripening-associated polygalacturonase and expansin influences tomato cracking显示文摘Fruit cracking is an important problem in horticultural crop production.Polygalacturonase(SlPG)and expansin(SlEXP1)proteins cooperatively disassemble the polysaccharide network of tomato fruit cell walls during ripening and thereby,enable softening.A Golden 2-like(GLK2)transcription factor,SlGLK2 regulates unripe fruit chloroplast development and results in elevated soluble solids and carotenoids in ripe fruit.To determine whether SlPG,SlEXP1,or SlGLK2 influence the rate of tomato fruit cracking,the incidence of fruit epidermal cracking was compared between wild-type,Ailsa Craig(WT)and fruit with suppressed SlPG and SlEXP1 expression(pg/exp)or expressing a truncated nonfunctional Slglk2(glk2).Treating plants with exogenous ABA increases xylemic flow into fruit.Our results showed that ABA treatment of tomato plants greatly increased cracking of fruit from WT and glk2 mutant,but not from pg/exp genotypes.The pg/exp fruit were firmer,had higher total soluble solids,denser cell walls and thicker cuticles than fruit of the other genotypes.Fruit from the ABA treated pg/exp fruit had cell walls with less water-soluble and more ionically and covalently-bound pectins than fruit from the other lines,demonstrating that ripening-related disassembly of the fruit cell wall,but not elimination of SlGLK2,influences cracking.Cracking incidence was significantly correlated with cell wall and wax thickness,and the content of cell wall protopectin and cellulose,but not with Ca^(2+)content.Fangling Jiang Alfonso Lopez Shinjae Jeon Sergio Tonetto de Freitas Qinghui Yu Zhen Wu John M.Labavitch Shengke Tian Ann L.T.Powell Elizabeth Mitcham 2019Horticulture Research2019,6,1:13
2Anti-porcine circovirus type 2(PCV2) antibody placental barrier leakage from sow to fetus: impact on the diagnosis of intra-uterine PCV2 infection显示文摘Dear Editor,Fetuses develop antibodies when they are infectedwith porcine circovirus type 2(PCV2).At abortion orbirth,both PCV2 and/or anti-PCV2 antibodies can thenbe detected.Finding anti-PCV2 antibodies in aborted fe-tuses or stillborn piglets is generally used as evidence ofan intra-uterine PCV2 infection.However,a recent anal-ysis of fetuses sent in for PCV2 diagnosis and caesare-an-derived,colostrum-deprived pigs revealed thatDipongkor Saha Rubén Del Pozo Sacristán Nicolaas Van Renne Liping Huang Ruben Decaluwe Annelies Michiels Alfonso Lopez Rodriguez Maria José Rodrí-guez Margarita García Durán Ilse Declerk Dominiek Maes Hans J.

3Multimodality functional imaging using DW-MRI and 18F-FDG-PET/CT during radiation therapy for human papillomavirus negative head and neck squamous cell carcinoma: Meixoeiro Hospital of Vigo Experience显示文摘AIM To noninvasively investigate tumor cellularity measured using diffusion-weighted magnetic resonance imaging(DW-MRI) and glucose metabolism measured by 18 Flabeled fluorodeoxyglucose positron emission tomography/computed tomography(18F-FDG-PET/CT) during radiation therapy(RT) for human papillomavirus negative(HPV-) head and neck squamous cell carcinoma(HNSCC).METHODS In this prospective study, 6 HPV- HNSCC patients underwent a total of 34 multimodality imaging examinations(DW-MRI at 1.5 T Philips MRI scanner [(n = 24) pre-, during-(2-3 wk), and post-treatment(Tx), and 18F-FDG PET/CT pre- and post-Tx(n = 10)]. All patients received RT. Monoexponential modeling of the DW-MRI data yielded the imaging metric apparent diffusion coefficient(ADC) and the mean of standardized uptake value(SUV) was measured from 18F-FDG PET uptake. All patients had a clinical follow-up as the standard of care and survival status was documented at 1 year.RESULTS There was a strong negative correlation between the mean of pretreatment ADC(ρ =-0.67, P = 0.01) and the pretreatment 18F-FDG PET SUV. The percentage(%) change in delta(?) ADC for primary tumors and neck nodal metastases between pre- and Wk2-3 Tx were as follows: 75.4% and 61.6%, respectively, for the patient with no evidence of disease, 27.5% and 32.7%, respectively, for those patients who were alive with disease, and 26.9% and 7.31%, respectively, for those who were dead with disease.CONCLUSION These results are preliminary in nature and are indicative, and not definitive, trends rendered by the imaging metrics due to the small sample size of HPV- HNSCC patients in a Meixoeiro Hospital of Vigo Experience.David Aramburu Núnez Antonio Lopez Medina Moisés Mera Iglesias Francisco Salvador Gomez Abhay Dave Vaios Hatzoglou Ramesh Paudyal Alfonso Calzado Joseph O Deasy Amita Shukla-Dave Victor M Munoz 2017World Journal of Radiology2017,9,1:2
