摘要： Pea is a seed legume.It is rich in cellulose fibre and protein.It is also a significant source of minerals and vitamins.In this paper,we set out to better characterize the physiological responses of Pisum sativum L.to the combined effects of NaCl,100 mM and gibberellins(GA3).Our analysis revealed that NaCl caused a decrease in growth resulting in a reduction in root elongation,distribution and density,leaf number and leaf area,and a decrease in dry matter of roots and shoots.However,the contribution of GA3 in the salty environment induced an increase in these different parameters suggesting an improving effect of this hormone on growth of pea in presence of salt.NaCl also led to a disturbance of the photosynthetic machinery.Indeed,level of chlorophyll pigments(a and total)and photosynthetic activity were decreased compared to the control plants.However,the exogenous supply of GA3 restored this decrease in net CO2 assimilation,but not in chlorophyll content.Additional analyses were performed on the effect of salinity/GA3 interaction on osmolytes(soluble sugars and starch).Our results showed an increase in sugars and a decrease in starch in the presence of 100 mM NaCl.The salt-GA3 combination resulted in compensation of soluble sugar contents but not of starch contents,suggesting a beneficial effect of GA3 under saline stress conditions.Level of three main polyamines putrescine,spermidine,and spermine increased significantly in all organs of salt-treated plants.

摘要： Recovering the iron(Fe)and phosphorus(P)contained in steelmaking slags not only reduces the environmental burden caused by the accumulated slag,but also is the way to develop a circular economy and achieve sustainable development in the steel industry.We had pre-viously found the possibility of recovering Fe and P resources,i.e.,magnetite(Fe_(3)O_(4))and calcium phosphate(Ca_(10)P_(6)O_(25)),contained in steel-making slags by adjusting oxygen partial pressure and adding modifier B_(2)O_(3).As a fundamental study for efficiently recovering Fe and P from steelmaking slag,in this study,the crystallization behavior of the CaO-SiO_(2)-FeO-P_(2)O_(5)-B_(2)O_(3) melt has been observed in situ,using a confocal scanning laser microscope(CLSM).The kinetics of nucleation and growth of Fe-and P-rich phases have been calculated using a classical crys-tallization kinetic theory.During cooling,a Fe_(3)O_(4) phase with faceted morphology was observed as the 1st precipitated phase in the isothermal interval of 1300-1150°C,while Ca_(10)P_(6)O_(25),with rod-shaped morphology,was found to be the 2nd phase to precipitate in the interval of 1150-1000°C.The crystallization abilities of Fe_(3)O_(4) and Ca_(10)P_(6)O_(25) phases in the CaO-SiO_(2)-FeO-P_(2)O_(5)-B_(2)O_(3) melt were quantified with the in-dex of(T_(U)−T_(I))/T_(I)(where T_(I) represents the peak temperature of the nucleation rate and TU stands for that of growth rate),and the crystalliza-tion ability of Fe_(3)O_(4) was found to be larger than that of Ca_(10)P_(6)O_(25) phase.The range of crystallization temperature for Fe_(3)O_(4) and Ca_(10)P_(6)O_(25) phases was optimized subsequently.The Fe_(3)O_(4) and Ca_(10)P_(6)O_(25) phases are the potential sources for ferrous feedstock and phosphate fertilizer,respectively.

摘要： Objective:Protein convertase subtilisin/Kexin type 9(PCSK9)has been found to be closely associated with the occurrence and development of numerous tumors.However,the precise role of PCSK9 and its relationship to the development of hepatocellular carcinoma(HCC)remain largely unknown.This study aimed to clarify these issues.Methods:The expression levels of PCSK9 in HCC tissues and HCC cell lines were determined by the quantitative reverse transcription polymerase chain reaction,Western blot,and immunohistochemical analyses,and the effects of PCSK9 expression on HCC cell biological traits were investigated by overexpressing and downregulating PCSK9 expression in vivo and in vitro.Additionally,the mechanism by which PCSK9 mediated dissociation of glutathione S-transferase Pi 1(GSTP1)dimers and phosphorylation of the Jun N-terminal kinase(JNK)pathway components were investigated.Results:PCSK9 expression levels were significantly lower in HCC tissues than in adjacent non-tumor samples.In vivo and in vitro experiments suggested that PCSK9 inhibited HCC cell proliferation and metastasis.Further analysis showed that PCSK9 interacted with GSTP1 and promoted GSTP1 dimer dissociation and JNK signaling pathway inactivation in HCC cells.Moreover,the relationships between PCSK9 protein expressions and clinical outcomes were investigated.The PCSK9-lo group displayed a significantly shorter overall survival(OS;median OS:64.2 months vs.83.2 months;log-rank statistic:4.237;P=0.04)and recurrencefree survival(RFS;median RFS:26.5 months vs.46.6 months;log-rank statistic:10.498;P=0.001)time than the PCSK9-hi group.Conclusions:PCSK9 inhibited HCC cell proliferation,cell cycle progression,and apoptosis by interacting with GSTP1 and suppressing JNK signaling,suggesting that PCSK9 might act as a tumor suppressor and be a therapeutic target in HCC patients.

摘要： Climate change poses many risks to economically and ecologically crucial species.Longleaf pine(Pinus palustris Mill.)trees are keystone species that were once dominant across the southeastern United States,but now occupy less than 5%of their historic range and are thus classified as endangered.Here we review the current status and challenges facing longleaf pine trees,what is known on how changing climate will impact longleaf growth and reproduction,and gaps in the literature that are important to address.We found that many fundamental aspects of longleaf pine growth and reproduction are understood.However,these systems are complex,and not all is known about each factor that influences the relationship between climate,growth,and reproductive output.Additionally,long-term data sets capable of examining all relevant factors in these relationships do not currently exist.To fill necessary gaps,we recommend a joint approach between using readily available data sets and establishing new long-term monitoring plots targeted to collect data on missing or poorly understood conditions.This review provides a clue from an ecological complexity perspective to understand and manage longleaf pine forests under climate change.

摘要： Early life intervention is important to shape the gut microbiome profiles of adult animals due to the tremendous alteration of diet components. Nevertheless, there is still no unified understanding about its long-term effects in lambs. In this study, sixty 20-day-old lambs were assigned into ewe-rearing(ER) and artificial-rearing(AR) treatments to evaluate the effects of AR strategy on ruminal microbiota, fermentation, and morphology of pre-weaning lambs(from 20 to 60 days of age) and its long-term effects in the fattening stage(from 61 to 180 days of age). During the pre-weaning stage, ER lambs were breastfed and supplemented starter, while AR lambs were artificially fed with milk replacer and starter. During the fattening stage, all lambs in both treatments were fed with the same fattening diets. At 60, 120 and 180 days of age, 6 lambs from each group were slaughtered to collect rumen content and tissue samples. Compared with ER lambs, the dry matter feed intakes of AR lambs increased(P0.05), it was higher(P<0.05) in AR lambs compared with ER lambs at the fattening stage. The rumen keratin layer of AR lambs was thinner(P<0.05) than that of ER lambs. Along with lamb growth from 60 to 180 days of age, the differences in rumen bacterial diversity between AR and ER treatments grew more distinct(P<0.05). Compared with ER lambs, AR lambs increased(P<0.05) rumen bacteria abundance, such as phylum Spirochaetes and genus Treponema at 60 days of age, phylum Actinobacteria and genus Succiniclasticum at 120 days of age, and phylum Proteobacteria at 180 days of age, but decreased genus Selenomonas from 60 to 180 days of age, and Anaerovibrio at 180 days of age. In summary, the early interventions before weaning could improve dry matter feed intake of lambs, which triggered robust rumen development and produced positive long-term effects on rumen fermentation and noticeable weight gain of fattening lambs. It suggests that the artificial rearing strategy is effective in improving rumen fermentation and microbial maturity of intensive fattening lambs.

摘要： Introduction: Low birth weight (LBW) is defined as a birth weight 2500 g at birth, regardless of the term of pregnancy. The objective of this study is to evaluate their stature and weight growth from 0 to 9 months of corrected age (CA) in Senegal. Methodology: This is a prospective, descriptive, and analytical cohort follow-up up to 9 months of CA including all live newborns of LBW hospitalized and followed up from 01 August 2019 to 31 May 2020. World Health Organization growth charts were used to assess stature and weight growth. Results: During the study 136 LBW newborns were included. The mean gestational age was 32 weeks of amenorrhea. At discharge, 46 children (33.82%) were exclusively breastfed. At birth, the mean weight was 1487 g (3rd-10th percentile) and the mean height was 41.52 cm (10th-25th percentile). At 9 months of CA, the mean weight was 8119 g (median) and the mean height was 74 cm (median). The children had achieved satisfactory growth in weight (84%) and height (89%). At 9 months of CA, 27% of the children were behind in one of the four areas of psychomotor development. Conclusion: At the end of 9 months of CA, stature and weighted growth was normal.

摘要： In agriculture,LED light sources have increasingly replaced the standard luminescent lamps and have acquired an important role in plant micropropagation.We studied the effect of different light sources such as narrow-band LEDs(bright blue,blue,green,yellow,deep red,and red)and wide-band LEDs(cold white,white,warm white,full spectrum,and an artificial solar spectrum sun box constructed by us)on development of potato plantlets in vitro.White luminescent lamps were used as a control.The light intensity of 49μmol·m^(-2)·s^(-1)was provided in all light treatments.We showed that the long-wave narrow-band light treatments were inapplicable for potato micropropagation,because plantlets were weak with small leaves,inhibited roots,and significantly elongated stems.Blue lights provided growth of shortened plantlets with large leaves,well-growing roots,and abundant green mass.The chlorophyll content was lower under blue and bright blue light and was at the same level in the remained treatments.Significant differences in the stomatal apparatus development were observed depending on the light source.These differences were not always reflected in the plantlet phenotype:e.g.,plantlets under blue and bright blue lights showed no differences in any characteristics except stomatal density and size of stomatal guard cells.We found no significant effect of blue light portion in the white lights and full spectrum on plantlet growth.An artificial solar spectrum sun box was the most suitable for potato micropropagation,because it supported the development of plantlets with good fitness,uniform internodes length,abundant roots and green mass accumulation.

摘要： In domestic animals,the body weight is the ultimate result of growth which forms the basis of meat production.Sex,nutrition,breed and health are the main factors which influence the growth rate in animals.Heredity which is the major factor affecting the prenatal growth either directly through the genotype of the fetus or indirectly through the genotype of the dam.The prenatal growth patterns and development of the camel fetus is just like the fetus of cattle,however,the meat output from the breeding she-camels is limited often due to longer gestation periods,longer milk feeding periods,lower calving rates under traditional management system.A lot of variation regarding camelid daily growth rate exists that varies widely between breeds,within breeds and regions.There is a significant effect of pre-weaning and post-weaning growth rates on the final body weights in camelids.Management system,the available milk quantity,husbandry practices and vegetative conditions are the main factors that affect the pre and post weaning growth rates of camel calves.However,it is partially dependent on the availability of browsing species throughout the whole year.In this specific study,an effort has been drawn to look into the literature data for camel growth assessment.

摘要： Seed size and the growth environment are important variables that influence seed germination, growth and biomass of seedlings and future tree harvest and should thus be taken into account in agroforestry and reforestation programmes for endangered species like Pterocarpus erinaceus. In the present study, to assess seedling germination and vigour in P. erinaceus as a function of seed size in two environments, 1080 seeds and 360 seedlings were evaluated at two separate sites in Côte d'Ivoire. The results show that large seeds had very high germination rates (up to 100%) and produced more vigorous plants better able to adapt to climate change. The maternal environment and seed size had a significant influence on seed germination (P < 0.05) and seedling development (P < 0.05) and biomass (P < 0.05). Seedlings were most successful at the site with a humid tropical climate (Daloa). Seedling leaves had the same resistance regardless of seed size and study site, but leaf moisture content was more stable in seedlings grown from medium and small seeds. These results will help guide conservation strategies for the species and are key factors for rural populations, loggers, and forest management structures for the silviculture of this species.
