ABSTRACT Knowing the proliferative capacity of herbicide-resistant weeds is the basis for the integrated management. We collected seeds of two Echinochloa glabrescens Munro ex Hook. f. populations (TS and WH) from rice (Oryza sativa L.) fields in eastern China (F0 populations), and those from individuals surviving the initial metamifop treatment (F1 lines) were tested for their responses to metamifop, and common garden experiments were conducted to compare their productivities. We found that TS was highly resistant to metamifop, and WH was susceptible. After treated with metamifop at the label dose (120 g ai ha-1), averagely 56% and 16% of TS and WH F1 lines contained surviving seedlings, and averagely 24% and 1% F1 seedlings survived among total seedlings of the same population, respectively. After treated with metamifop at a dose of 0, 60, 120 or 240 g ai ha-1, surviving F0 plants escaped from higher doses reproduced higher proportions of metamifop-resistant F1 progenies in both populations. At 120 d after sowing (DAS), TS individuals surviving 2 × label dose of metamifop showed nonsignificant difference in plant heights, biomass and seed production, compared with relative control treatment; while WH plants surviving the label dose of metamifop decreased seed production by 25%-39%. One WH and TS plant individual surviving metamifop treatment at the label dose may generate 10-21 and 490-701 progenies resistant to the label dose of metamifop, respectively.

Abstract Background. The aim of the study was to explore the safety and efficacy of percutaneous transforaminal endoscopic discectomy (PTED) and fenestration discectomy (FD) in the treatment of lumbar disc herniation (LDH). Material and methods. The complete clinical data from 87 patients with LDH from our hospital were retrospectively analyzed. Patients were divided into a control group (n = 39, treated with FD) and a research group (n = 48, treated with PTED) according to the prescribed treatments. The basic operation conditions were compared across the two groups. Surgical outcomes were assessed. The incidences of complications and the life quality of patients were evaluated 1 year after surgery. Results. The patients in both groups completed the operation. The visual analog scale and Oswestry Disability Index score of patients in the research group was significantly lower while the Orthopaedic Association Score was significantly higher after surgery. The success rate of the operation in the research group which was significantly higher and the rate of complications was significantly lower. No statistical differences in the quality of life were observed between the patients (p > 0.05). Conclusions. PTED and FD are effective in the treatment of LDH. However, our study showed that PTED has a higher rate of treatment success, faster recovery times and is safer than FD.

Abstract To explore a new method for the detection of soluble solids content (SSC) in apples, the reflectance spectra of apples with different SSC were obtained based on hyperspectral imaging technology in this paper, and fractal measurement of the reflection spectrum curve was carried out based on fractal theory, for using fractal dimension to quantitatively reflect its SSC. The results show that the samples with different SSC have little difference in fractal dimension, and are not sensitive to the change of apple SSC, which cannot show an obvious linear relationship. It can be considered to conduct a study on discrimination with obvious differences between spectral curves, such as variety discrimination and damage discrimination.

ABSTRACT This study investigated oxidative damage and exocrine dysfunction of fetal pancreas caused by maternal nutritional restriction. Eighteen ewes carrying singleton fetus were randomly divided into control group (CG, ad libitum, 0.67 MJ ME/BW0.75/d, n = 6), restricted group 1 (RG1, 0.33 MJ ME/BW0.75/d, n = 6), and restricted group 2 (RG2, 0.18 MJ ME/BW0.75/d, n = 6) at d 90 of pregnancy. Maternal undernutrition was imposed from d 90 to 140 of pregnancy. At 140 d of gestation, fetal blood and pancreas tissue were collected to determine fetal pancreatic extracellular matrix, antioxidant capacity, and indicators of exocrine dysfunction. With the decrease of maternal nutrition, the fetal body weight, pancreatic weight, and DNA content were reduced in RG2 compared with CG, and increased and thickened collagen fibers were observed in RG2. Fetuses in RG2 exhibited increased collagen 3 (COL3) and fibronectin (FN) levels relative to CG, and the COL1:COL3 ratio was lower than that of the CG. For RG1, we found increased COL3 compared with CG. Malondialdehyde, serum amylase, and serum lipase in fetal pancreas in RG2 increased, but the total antioxidant capacity (T-AOC) decreased compared with the CG. The impaired ovine fetal pancreas growth, antioxidant imbalance, and pancreatic exocrine dysfunction are induced by maternal undernutrition during late pregnancy.

Abstract Dried radish is a kind of pickled vegetable product with a unique taste made from radish via traditional solid-state spontaneous fermentation. In this study, the effects of variety on physicochemical indexes, texture properties, and taste substances of spontaneous fermented dried radish were investigated. As a result, processing and fermentation had similar trends for all radish varieties. The pH value decreased slightly, soluble solid increased with the decrease of moisture content, the hardness and chewiness decreased, while the content of organic acids and free amino acids increased. Furthermore, the variety of raw material is the key to affecting product quality and taste. The dried radish processed by the variety P21-25 presents the best texture, the highest content of sweet amino acids, the most abundant component of organic acids, while having the lowest salinity. These results indicated that radish varieties could significantly influence the quality and taste of dried radishes under the same processing and fermentation conditions. These findings reveal the importance of variety selection for the quality and taste of spontaneous fermented dried radish, and provide theoretical support for the processing and application of green radish varieties.

Abstract This study aimed to investigate the molecular mechanism of Picrasma quassioides Benn against inflammation by means of network pharmacology. The paper will provide a reference for multi-target and multi-channel treatment of inflammation with traditional Chinese medicine. Through screening and analysis, 11 active ingredients and 109 anti-inflammation prediction targets were obtained and constructed a compound-target network. The targets such as VEGFA, TLR4 and STAT3 may play a crucial role. Network enrichment analysis showed that the 109 potential targets constitute a number of pathways or inflammatory reactions closely related to inflammation, including NF-κB signaling pathway and MAPK signaling pathway. The docking results indicated that the binding energy of Picrasidine Y and the inflammatory factors VEGFA is the highest. This study predicted the role of multiple active compounds in the alkaloids of Picrasma in the inflammatory response, and provided a theoretical basis for the anti-inflammatory mechanism of Picrasma.

Abstract To perform dermatoglyphics analysis and to explore the possible relationships between dermatoglyphic characteristics and sports level of Chinese table tennis players. A total of 92 Chinese professional table tennis players were recruited and divided into ordinary group and excellent group according to their levels. Their dermatoglyphic patterns on the palms and fingers were collected and statistically analyzed. Our results showed that the data revealed significant differences (p < 0.05) between the ordinary group and the excellent group in terms of atd angle, thenar eminence, total number of a-b ridges and double loop whorl, while no significant differences (p > 0.05) were observed in concentric whorl, arch pattern and loop pattern. In conclusion, these findings may provide experimental evidence for the application of dermatoglyphic analysis as a tool for future selection of elite table tennis players.

Abstract Selenium (Se) is a nutritionally important micronutrient for humans. The use of Se fertilizers is often the most feasible approach to precisely increase Se contents in rice grains, but the effects of common commercial Se fertilizers on producing Se-rich rice remain to be investigated. In this study, we compared the effects of liquid and granular Se fertilizers on the accumulation of Se and heavy metals in rice grains of four different varieties in field. Results showed that Se accumulation in rice grains was affected by the form of fertilizers, applied concentrations of Se fertilizers, and rice varieties. Liquid fertilizer displayed significantly higher Se transfer efficiency than granular fertilizer, whereas the granular fertilizer had a slightly higher effect on organic Se accumulation. More than 95.5% Se in grains were organic Se, with selenomethionine (SeMet) being the dominant one. The proportion of organic selenocysteine (SeCys2) in grains was significantly higher in treatments with liquid fertilizer. Both forms of fertilizers significantly reduced the accumulation of cadmium, lead, and arsenic. Collectively, our study provides a reference for producing Se-rich rice in a more competitive manner in practice.

Abstract To understand the research status and current dynamics of fruit quality detection and objectively reflect the influence of different countries, research institutions and authors in this field, the software CiteSpace was used to bibliometrically and visually analyze the relevant literature on fruit quality detection in Web of Science (WoS) database from 1982 to 2021. The results showed that the number of publications on fruit quality detection showed a trend of slow in the early stage, rapid in the middle stage and intensified in the late stage. China has the largest number of international publications, accounting for 21.80% of the WoS database, but its intermediary centrality is inferior to that of the United States, Germany, Italy and Spain; the United States is at the core of international cooperation, establishing cooperative relations with most countries; through keywords co-occurrence network and keyword clustering, it is concluded that the research mainly focuses on fruit quality detection based on spectral technology or electronic nose technology, fruit composition detection based on high-performance liquid chromatography (HPLC), fruit edible safety detection, and genetic analysis of fruit quality-related traits. Bibliometrics and visual analysis of this fruit quality detection research can provide a certain reference for relevant researchers.

Abstract Due to the good functional characteristics and nutritional value, ovalbumin (OVA) has a widely ranges of applications in food industry. But the characteristics of being susceptible to external conditions, such as processing, storage conditions and food ingredients, makes it display a relative lower functional property and limits its applications. Glycosylation is a natural, green approach of protein modifications that has an impact on its functional properties. In this work, we prepared the OVA-pectin conjugates through wet-heating and ultrasound glycosylation to investigate the effects on the functional and structural properties of OVA. Both wet-heating and ultrasound treated OVA at present of pectin showed higher emulsify and foam properties than untreated OVA. The results of particle size, SDS-PAGE, FT-IR, and SEM indicated that the covalent binding of pectin with OVA molecule. This study suggests that wet-heating and ultrasound glycosylation with pectin are promising method to improve the functional properties of OVA.
