The Chandipura vesiculovirus(CHPV),a single-stranded,negative sense RNA arbovirus with five structural proteins-the G,N,M,P,and L proteins-is the source of Chandipura virus infection.Children between the ages of 9 months and 14 years old are the most common recipients of CHPV infection,which is primarily spread by sand flies(Sergentomyia,Phlebotomus species).The potential advantages of black seeds(N.sativa)in the treatment of patients with CHPV infection are the main topic of our current review.The majority of patients infected with CHPV experience neurological complications such as encephalitis and other neurological complications.Since there is currently no approved antiviral treatment,supportive care and symptomatic therapy are the primary methods used to manage CHPV-infected patients.Herbal candidates possessing antioxidant,immunomodulatory,antiviral,and anti-inflammatory qualities may aid in the treatment of CHPV infection.The antiviral,anti-inflammatory,antioxidant,and immunomodulatory qualities of black seeds(N.sativa)have been shown in a number of preclinical and clinical investigations;these attributes could be helpful in the treatment of CHPV infection.Black seeds(N.sativa)may help treat CHPV-infected patients in the early stages of their illness when used in conjunction with symptomatic therapy and supportive care.In patients infected with CHPV,additional randomized controlled clinical trials would assess the efficacy and safety of black seeds(N.sativa). 展开更多

Mimetic seeds attract birds to disperse seeds mainly by mimicking fleshy fruits or arillate seeds,however,they provide little nutritive reward for bird dispersers.The key characteristics of mimetic seeds are conspicuous seed color,hard seed coat,certain toxic secondary metabolites,and perhaps smooth waxy layer.In this review,we discuss the global distribution of mimetic seeds,the interaction of mimetic seeds with bird dispersers,and secondary metabolites that underlie key characteristics of mimetic seeds.Mimetic-seed species mainly occur in the tropics,with large numbers distributed along coastal areas.The interaction between mimetic-seed species and bird dispersers can be antagonistic,mutualistic,or both.These interactions are generally established by conspicuous visual cues and hard tactile cues from mimetic seeds.The formation and variation of key characteristics of mimetic seeds may contribute to the metabolism of several kind of secondary compounds.Here,we also discuss mimetic-seed dispersal in the context of an evolutionary game,and propose several aspects of mimetic-seed dispersal that remain unstudied.While this review is based on preliminary findings and does not account for other potential influencing factors such as climate,it is expected to contribute to an improved understanding of mimetic-seed dispersal. 展开更多

The aim of the present study was to evaluate the effects of baobab seed washing and origin on the chemical composition of the oil extracted by pressing. Six (6) oil samples were obtained from seeds of three (3) geographical origins. The identification and quantification of fatty acids and the polyphenolic profile were carried out by GC-MS and HPLC-UV, respectively. Analysis of fatty acid methyl esters allowed the identification and quantification of 18 fatty acids. Oils from unwashed seeds were richer in palmitic (C16:0), stearic (C18:0), oleic (C18:1) and arachidic (C20:0) acids. In addition, HPLC-UV analysis at 279 nm shows that oils from unwashed seeds are richer in tyrosol, hydroxytyrosol and caffeic acid. With regard to the polyphenolic profile, gallic acid and quercetin were not detected in these baobab oils. Principal component analysis of fatty acid and phenolic compound content showed that oils from unwashed seeds would best preserve their chemical and associated potential bioactive characteristics. 展开更多

[ Objective] This study was to reveal the differences in crude fat and glucosinolates between self pollinated seeds and naturally pollinated seeds in Brassica napus in sichuan ecological region.. [ Method] Near-infrared spectroscopy method (NIRS) was employed to measure the quality components in self pollinated seeds and naturally pollinated seeds of 861 shares of Brassica napus from Sichuan ecological region. And correlation analysis and regression analysis were conducted based on the experimental data via SPSS (statistics package for social science). [ Result] The contents of crude fat in the self pollinated seeds were commonly a higher than that in the naturally pollinated seeds at 0.01 significant level; while the contents of glucosinolates in the self pollinated seeds and the naturally pollinated seeds were insignificantly different. Both the correlation relationship and linear regression for the crude fat between the self pollinated seeds and naturally pollinated seeds reached the significant level. The regression equations for the contents of crude fat(y1 ) and glucosinolates( y2 ) in the naturally pollinated seeds and of crude fat( x1 ) and glucosinolates( x2 ) in self pollinated seeds were respectively determined to be y1 = 16.844 +0.614x1 and y2 = -0.620 + 1.017 x2. [ Conclusion] In Brassica napus breeding, crude fat in naturally pollinated seeds should be emphatically taken into account, meanwhile concurrently considering that in self pollinated seeds; while glucosinolates in both the self pollinated seeds and the naturally pollinated seeds must be simultaneously concerned. 展开更多

The inflammatory response is a crucial physiological process that can lead to tissue damage and is considered a causative factor for various chronic diseases,such as rheumatoid arthritis.Recent research has focused on exploring valuable nutrients derived from Cannabis sativa L.(hemp)seeds,particularly hemp seed proteins.Therefore,this study aimed to investigate the release of anti-inflammatory peptides from Lactobacillus paraplantarum-fermented hemp seed proteins.To confirm the complete hydrolysis of hemp seed proteins during the fermentation process,sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE)was employed.Further,the isolation and purification of peptides were achieved through ultrafiltration.The identity of peptides was nextly established using ultra-high performance liquid chromatography coupled with hybrid quadrupole time-of-flight mass spectrometry(UHPLC-QTOF-MS).The results revealed a total of 39 identified peptides in fermented hemp seeds,with 9 peptides selected based on their relative quantity.Notably,AAELIGVP(P1),AAVPYPQ(P2),VFPEVAP(P4),DVIGVPLG(P6),and PVPKVL(P9)demonstrated strong anti-inflammatory abilities in lipopolysaccharide(LPS)-induced RAW264.7 macrophage cells.Molecular docking was used to understand the potential anti-inflammatory mechanism of these 5 peptides,and in silico results indicated that P1,P2,P4,P6,and P9 could bind to the active sites of toll-like receptor 4(TLR-4),nuclear factor-κB(NF-κB),and inhibitor of NF-κB kinase(IKK)with higher binding energies.Overall,these findings indicate that hemp seeds have potential to be a source of bioactive peptides for functional foods with anti-inflammatory properties. 展开更多

People living long-term in areas with UV will cause premature photoaging.An abnormal reduction in autophagy is a key feature of photoaging,and p38 MAPK has been regarded as a key regulator of autophagy.Isothiocyanate is one of the main active components of Moringa oleifera Lam.seeds.Studies have reported that M.oleifera Lam.seeds iso thiocyanate(MITC)has anticancer,anti-inflammatory,cardio metabolic repair,nervous system protection,blood lipid regulation and diabetes prevention properties.However,the molecular mechanisms of MITC with protective effects against skin photoaging have not been studied thus far.In this study,we aimed to evaluate the antiphotoaging activity of MITC and to investigate the effect of p38 MAPK-dependent autophagy in vivo and in vitro models of photoaging.In this research we found that MITC can reverse the intracellular reactive oxygen species(ROS)content and inhibit the activation of p38 MAPK to improve the autophagy level,reduce the expression of matrix metalloproteinases(MMPs),and finally protect against photoaging by UV.Our results will uncover the molecular mechanisms of MITC that play a role in the protective effects against skin photoaging,provide helpful information for developing MITC as an anti-photoaging plant material and improve the utilization of M.oleifera Lam.seeds. 展开更多

A study was conducted to determine the physiological characteristics changes of Aesculus chinensis seeds during natural dehydration in 2003. The results showed that A. chinensis seeds were recalcitrant with being highly desiccation-sensitive. The seed moisture content of fresh fruits was higher than 60%. When the seeds were naturally dried for 30 days, their moisture content declined to 30.2% and their viability was completely lost. The seed germination percentage had a small increase at the beginning of desiccation and then decreased rapidly. The relative electrical conductivity of the A. chinensis seeds increased along with a decrease in seed moisture content. However, there was an abnormal increase in relative electrical conductivity when the seed moisture content was between 53.7% and 50.9%. Superoxide dismutase (SOD) activity decreased rapidly in the period of desiccation except for an abnormality when the seed moisture content was between 53.7% and 50.9%. Malondialdehyde (MDA) content increased slowly at the early stage of desiccation and then rose rapidly after the moisture content was below 50.9%. The soluble sugar content in seeds slowly increased with the increasing period of desiccation. The seed germination percentage was at the high level when seed moisture content was in range of 47%- 60%, which suggests that this was the optimum moisture content for maintaining A. chinensis seed viability. 展开更多

[ Objective ] The research aimed to reveal theeffects of excessive Mg^2+ on the germination characteristics of maize and soybean. [ Method ] Eleven concentration gradients of Mg^2+ including 0, 40, 80, 120, 160,200,240,280,320,360 and 400 mmol/L were set up to study the effects of different treatments on such indices as the germination potential, germination rate, fresh weight, dry weight, root length, plant height and stem diameter of maize and soybean. [ Result] With the increasing of Mg^2+ concentration, the germination of maize delayed and the germination rate of soybean obviously decreased, reaching the significant difference at 0.05 level. When Mg^2+ concentration increased, the fresh weight and dry weight of maize and soybean decreased, but maize and soybean showed some adaptability. The growth of radicles and seedlings in maize and soybean were obviously inhibited by Mg^2+ , and atrophy and dysplasia phenomena appeared. [ Conclusion] Excessive Mg^2+ stress has different effects on the germination potential and germination rate of different crops and has obvious poisoning effects on the root and stem growth of crops. 展开更多

In 2030, 26.4 million new cases will be diagnosed, with 17 million deaths accounted worldwide. Prostate cancer is the sixth most common type in the world, and the second most commom in men. For Brazil, the number of new cases of prostate cancer in 2010 is estimated to 52,350. Treatment of prostate cancer may be by surgery, radiation or even vigilant observation. A method of radiotherapy which has been extensively used is brachytherapy, where Iodine-125 seeds are placed inside or next to the area requiring treatment. Iodine seeds can be introduced loose seeds or stranded in bioabsorbable polymers in order to increase the dosimetric coverage of the prostate and reducing the chance of seed migration. Data were gathered concerning the commercialization of loose seeds and stranded seeds, between 2005 and 2011, in Brazil. It was noted that the number of stranded seeds commercialized in Brazil (around 80%) has always been much greater than the number of loose seeds, reaching 90% last year. The main reason is the reduction of the seed migration events into other parts of the body, since there is a potential hazard even considering that no harmful effect has been observe. The data regarding dosimetry are still controversial, since the seeds that migrate is normally no more than 1%. 展开更多

[Objective] This study aimed to explore an effective method for rapid salt- extraction of high-quality genomic DNA from dried seeds of plants. [Method] Seeds of seven varieties of crops were ground into powder. A hundred milligrams of seed powder was added to extracting solution for high salt-extraction of genomic DNA. The yield and quality of extracted DNA were determined by using ultramicro UV/Vis spectrophotometer detection method, PCR and restriction enzyme digestion. [Result] About 619.67-1 811.21 ng of genomic DNA was extracted from per 100 mg of dried seed powder of seven varieties of conventional crops. A260/A280 ratios of the obtained DNA solution all ranged from 1.87 to 2.07, the purity and quality of PCR were suitable for PCR and restriction enzyme digestion. Clear target bands of specific endogenous gene fragments of seven varieties of crops were amplified by PCR, and the obtained DNA could be fully digested with EcoRV and Hindlll.[Conclusion] This method could be used for rapid extraction of high-quality genomic DNA from dried seeds. 展开更多

[Objective] This study aimed to identify the ultra-drying method most suitable for the storage of Chinese chive seeds through comparing different ultra-drying meth- ods. [Method] Through setting treatments including freezing, silica gel drying and heating drying at 50℃ as well as two controls, the effects of different drying methods for storing ultra-dried Chinese chive seeds were compared. [Result] There were no significant differences in the germination rate and seedling length between Chinese chive seeds treated with heating drying at 50℃ and those treated with either freezing or get drying at the initial stage of the storage. Storing of Chinese chive seeds previously treated with either heating drying at 50℃, or freezing or gel drying for 0-98 months at 20℃ hadn't caused any adverse effect on the germination rate of seeds. And the effect of different storage conditions on seedling length displayed earlier than that on the germination rate. There was no significant difference on seedling length between seeds treated with heating drying at 50℃ and those treated with freezing drying after stored for as long as 98 months, revealing similar efficacy on storing seeds. [Conclusion] Freezing drying requires huge investment and cost for perennial running, and silica gel drying is slow in drying and time-consuming. By contrast, heating drying at 50℃ is an economic and simple method, which can enable the Chinese chive seeds to sustain a longevity of eight years or more. 展开更多
