| 1 | Disassembly 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 | 2019 | Horticulture Research2019，6，1： | 13 |

| 6 | Evaluation of antiparasitic,anticancer,antimicrobial and hypoglycemic properties of organic extracts from Panamanian mangrove plants显示文摘Objective: To investigate 33 organic extracts of mangrove plants for: antiparasitic, anticancer, and antibacterial activities, as well as their ability to inhibit the activity of the α-glucosidase enzyme. Methods: Leaves from all different plant mangrove species located in five mangrove zones of the Pacific coast of Panama were collected according to standard procedures. Qualitative phytochemical analysis of the organic extracts was performed by thin layer chromatography. The antiparasitic activity against Plasmodium falciparum, Trypanosoma cruzi and Leishmania donovani, toxicity against Artemia salina, anticancer activity in MCF-7 cell line, and antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa of all organic extract were investigated according protocols stablished in our institution. Finally, the ability to inhibit the enzymatic activity of α-glucosidase was evaluated by monitoring the hydrolysis of p-nitrophenyl α-Dglucopyranoside. Results: Thirty-three different samples belonging to nine different species of vascular plants with seeds of true mangroves were collected. Triterpenoids, phenolics, and tannins were the main groups of compounds found in the sampled mangroves. Saponins, quinones, and coumarins were found in less than 50%of the samples. Laguncularia racemosa showed moderate activity against Plasmodium falciparum. None of the extracts presented anticancer activity. Rhizophora mangle exhibited potent activity against Staphylococcus aureus and Bacillus subtilis [(90.41 ±7.33)% and(96.02±6.14)% of inhibition]; Avicennia germinans and Conocarpus erectus had activity against Escherichia coli[(71.17±6.15)% and(60.60±5. 13)% of inhibition,respectively]. About 60% of the mangroves showed α-glucosidase inhibitory activity. In particular, extracts from Laguncularia racemosa, Pelliciera rhizophorae, Conocarpus erectus, Mora oleifera, and Tabebuia palustris species showed α-glucosidase inhibitory potential, with IC_(50) values of(29.45±0.29),(20.60±0.70),(730.06±3.74),(25.59±0.37), and(853.39±5.30) μg/mL, respectively. Conclusions: Panamanian mangroves are mainly a promising potential source of hypoglycemic compounds, specifically α-glucosidase inhibitors.These results highlight the therapeutic virtues of extracts from American mangrove plants. | Dioxelis Lopez Lilia Cherigo Alejandro de Sedas Carmenza Spadafora Sergio Martinez-Luis | 2018 | Asian Pacific Journal of Tropical Medicine2018，11，1： | 0 |
| 7 | Design and Implementation of a Rehabilitation Upper-limb Exoskeleton Robot Controlled by Cognitive and Physical Interfaces显示文摘This paper presents an upper limb exoskeleton that allows cognitive(through electromyography signals)and physical user interaction(through load cells sensors)for passive and active exercises that can activate neuroplasticity in the rehabilitation process of people who suffer from a neurological injury.For the exoskeleton to be easily accepted by patients who suffer from a neurological injury,we used the ISO9241-210:2010 as a methodology design process.As the first steps of the design process,design requirements were collected from previous usability tests and literature.Then,as a second step,a technological solution is proposed,and as a third step,the system was evaluated through performance and user testing.As part of the technological solution and to allow patient participation during the rehabilitation process,we have proposed a hybrid admittance control whose input is load cell or electromyography signals.The hybrid admittance control is intended for active therapy exercises,is easily implemented,and does not need musculoskeletal modeling to work.Furthermore,electromyography signals classification models and features were evaluated to identify the best settings for the cognitive human–robot interaction. | Arturo Gonzalez‑Mendoza Ivett Quinones‑Uriostegui Sergio Salazar‑Cruz Alberto‑Isaac Perez‑Sanpablo Ricardo Lopez‑Gutierrez Rogelio Lozano | 2022 | Journal of Bionic Engineering2022，19，5： | 0 |

| 9 | Auditory function in symptomatic patients recovered from SARS-CoV-2 and unexposed patients:An analytical cross-sectional study显示文摘Objective:To describe audiological symptoms,audiometric profile,and distortion product otoacoustic emission in symptomatic patients recovering from SARS-CoV-2 infection(positive RT-PCR test)and asymptomatic patients(negative RT-PCR test).Methods:An analytical cross-sectional study was conducted using data obtained from clinical charts,physical examination,audiometry,and distortion product otoacoustic emission on 40 patients[case patients(CP)]recovering from SARS-CoV-2 infection diagnosed by a positive RT-PCR test and 22asymptomatic participants with a negative RT-PCR test[non-case(NC)].Results:Sixty-two patients(mean age:31.1 and 28.2 years in the CP and NC groups,respectively)were included.All participants were young without significant comorbidities,risk factors for hearing loss or otological history.Vertigo(5%),tinnitus(17.5%)and aural fullness/hearing loss(35%)were found in the CP group.A statistically significant difference was found in specific frequencies(1000,4000,and 8000 Hz)and pure tone average(low and high conversational frequencies with increased threshold in the PC group compared with the NC group),which was not found in distortion product otoacoustic emission.Conclusion:Audiovestibular symptoms are frequent in symptomatic patients recovering from SARS-CoV-2 infection.SARS-CoV-2 infection was consistently associated with an increased audiometric hearing threshold at specific frequencies and low tone average. | Katherin Andrea Borda Pedraza Sergio Mauricio Moreno Lopez Javier Amaya-Nieto Liliana Akli Serpa Ginna Paola Saavedra Martínez Mauricio Ernesto Quinche Pardo Alberto Pena Valenzuela | 2023 | Journal of Otology2023，18，3： | 0 |
