The mixedtreatment comparison meta-analysis within a Bayesian framework was performed using WinBUGS14 software.The proportions of patients reaching clinical response,clinical remission and mucosal healing in induction and maintenance phases were analyzed as efficacy indicators. Serious adverse events in maintenance phase were analyzed as safety indicators.RESULTS: The meta-analysis results showed that biological agents achieved better clinical response,clinical remission and mucosal healing than placebo.Indirect comparison indicated that in induction phase,infliximab was more effective than adalimumab in inducing clinical response(OR = 0.41, 95%CI:0.29-0.57), clinical remission(OR = 0.33, 95%CI:0.19-0.56) and mucosal healing(OR = 0.33, 95%CI:0.19-0.56), and golimumab in inducing clinical response(OR = 0.66, 95%CI: 0.39-2.33) and mucosal healing(OR = 2.15, 95%CI: 1.18-4.22). No significant difference was found between placebo and biological agents regarding their safety.CONCLUSION: All biological agents were superior to placebo for UC treatment in both induction and maintenance phases with a similar safety profile, and infliximab had a better clinical effect than the other biological agents.展开更多

Biochemical and pathogenicity tests, alongside PCR analyses, were conducted to identify the local isolates of Erwinia amylovora. The alternative antagonistic microorganisms which combat bacterium E. amylovora were tested within in vitro and in vivo conditions. The results revealed the ability of Streptomyces antagonistic bacteria to decrease fire blight severity on pear and apple trees during the first stage of the fire blight disease in leaf tissues. Streptomyces strain C1-4 suppressed E. amylovora disease symptoms in the leaf tissues and excised apple and pear shoots. The incidence of fire blight on leaves was reduced by about 70% with two applications of bacterial antagonists. Further studies at different locations in Kyrgyzstan, using large scale application, would allow for stronger recommendations to be made, including studies and recommendations on their ability to prevent disease and to use them as main components in an integrated pest management program.展开更多

Two concentrations (2.632×10^6 PIB·ml^-1 and 2.632×10^7 PIB·ml^-1) of Lymantria dispar L. NPV were sprayed on the 2rd-instar-larvae of L. dispar and 70% and 77.8% control effect were obtained respectively. BtMP0-342 was applied to the 3rd- and 4th-instar larvae and the control effect was around 80%. The sex-attractant provided by Canada Pacific Forestry Research Center also showed a good result in trapping L. dispar adults. The self-produced botanical insecticide, which was extracted from a kind of poisonous plant distributed in Daxing'an Mountains, China, exhibited a good control result in controlling the larvae of L. dispar, and 82% mortality was observed when spraying primary liquid of the botanical insecticide on the 3rd-5th-instar-larvae in lab.展开更多

In order to clear the suitable dosage of different biological agents for controlling cotton Verticillium wilt, field split plot experiment was designed to research the control effects of Bacillus subtilis WP (15, 30 and 45 kg/hm^2), Shibeijian Trichoderma harzianum (15, 18 and 24 kg/hm^2), Yufeng“99”(15, 22.5 and 30 kg/hm^2), Zhongnonglukang (30, 45 and 60 kg/hm^2) and Athomin (45, 60 and 75 kg/hm^2) on cotton Vertillium wilt in 2016 and 2017. The disease control effect against cotton Verticillium wilt, cotton growth, cotton yield and fiber quality were compared and analyzed by biometrical method. The results showed that five biological agents significantly reduced the incidence rate and disease index of cotton Verticillium wilt, and the average control effect reached 33.50%-74.94%. The control effect of Shibeijian T. harzianum dripped at the dosage of 18 kg/hm^2 was significantly higher than that dripped at 15 and 24 kg/hm^2. There was no significant difference between different application dosages in Athomin treatment. The control effect of the remaining three agents had significantly positive correlation with application dosage. Five biological agents had obvious promotion effects on cotton growth, and the cotton height, width of the top fourth leaf, fruit branch number and boll number per plant were increased in different levels. The cotton height and width of the top fourth leaf had no obvious changes with the increase of dosage, while the fruit branch number and boll number increased with the increasing dosage. Meanwhile, these biological agents significantly advanced the maturity of cotton. Except for Athomin treatment, the cotton seed yield in other treatments showed an increasing trend and increased significantly with the increasing dosage. The cotton fiber length and fiber breaking tenacity were improved slightly, but cotton quality had not been improved conspicuously. Therefore, according to disease control effect, cotton growth and yield performance, the suitable drip dosage of biological agents were as follows: Yufeng "99" 30 kg/hm^2, Zhongnonglukang 60 kg/hm^2, B. subtilis WP 45.0 kg/hm^2, and Shibejian T. harzianum 18.0 kg/hm^2. The drip dosage of Athomin still needs to be further studied.展开更多

Systemic biological agents that target specific immune molecules or cells such as tumor necrosis factor(TNF)-α, interferone-α, interleukin(IL)-1, IL-6, or B cells have been used in an attempt to treat Sjogren's syndrome. However, the efficacy of systemic biological agents, other than B-cell targeting agents, has not yet been confirmed in Sjogren's syndrome. Several studies have recently evaluated the efficacy of topical administration of biological agents targeting cytokines in the treatment of dry eye disease. Topical blockade of IL-1 by using IL-1 receptor antagonist could ameliorate clinical signs and inflammation of experimental dry eye. Using a mouse model of desiccating stress-induced dry eye, we have demonstrated that topical application of a TNF-α blocking agent, infliximab, could improve tear production and ocular surface irregularity, decrease inflammatory cytokines and Th-1 CD4+ cells on the ocular surface, and increase gobletcell density in the conjunctiva. Although controversy still remains, the use of topical biological agents targeting inflammatory cytokines may be a promising therapy for human dry eye disease.展开更多

Natural isolates of Venturia inaequalis were isolated from diseased parts of apple trees, selected from different regions, through sedimentation of air microflora on the crowns of fruit trees. Two biocontrol agents as Trichoderma viride and Streptomyces sр. were tested for apple scab control in vitro and field conditions. Two applications of Trichoderma viride within 35 days completely stopped the scab disease in seedling leaves. Within 40 days, the seedlings were recovered;the new leaves have blossomed on branches. The Streptomyces sp. antagonists were inferior in effectiveness compared to Trichoderma viride;nevertheless, they prevented progression of the disease in the leaves. Seedlings grew new shoots and leaves around 50 days after the second treatment. Orchard experiment results provide great hope that a biological product based on Trichoderma viride could work as an effective agent to suppress the development of the pathogen in the early spring, when leaves start to show scab disease symptoms.展开更多

Recently, a new class of drugs obtained by a biological process and therefore defined as “biologics” has been successfully used in the treatment of immunemediated rheumatic diseases. These drugs target different pro-inflammatory cytokines including tumor necrosis factor-α, interleukin-1 and interleukin-6, or immune effector cells including B and T lymphocytes. Their use has been then extended to different forms of uveitis resistant to standard therapy in small uncontrolled trials, with general and unexpected efficacy. The present review analyzes the literature on treatment of uveitis with the biologics currently available for the treatment of inflammatory rheumatic diseases. We used PubMed search engine as the main source of information. Among the papers included in the reference list, a particular emphasis was given on articles published during the last 5 years.展开更多

This research aims to increase the biological activities of natural syringaldehyde. The synthesis of syringaldehyde derivatives and controls the size of the material particles in the nanometer ranges. Nano-organic compounds (L1 - L2) and nano-organometallic compounds (C1 - C4) are used for the study of physicochemical characterization and biological activities. Antioxidant capacities were the DPPH and FRAP techniques, and bacterial abilities against Escherichia coli, Salmonella spp. and Staphylococcus aureus. The syringaldehyde salicylic hydrazone (L2) showed a high scavenging ability to DPPH. Free radical exhibited with IC<sub>50</sub> values as low as 51.109 ppm. The ability of antioxidants by FRAP showed that substances are capable of reducing Fe<sup>3+</sup> and most of C3, the ability to inhibit the growth of bacteria with the lowest MIC and MBC values and the ability to Chilo polychrysus (Meyrick) found that C1 and C2 showed LT<sub>50</sub> at 24 h and 48 h (19.00 and 19.33). These particles should develop as biological agents to reduce the use of chemicals that are harmful to humans and the environment.展开更多

Due to the involvement of branchedchain amino acids in various metabolic pathways, there has been a surge of interests in valine nutrition and its role in animal physiology. In pigs, the interactions between valine and other branched-chain amino acids or aromatic amino acids are complex. In this review, we delve into the interaction mechanism, metabolic pathways, and biological functions of valine. Appropriate valine supplementation not only enhances growth and reproductive performances, but also modulates gut microbiota and immune functions. Based on past observations and interpretations, we provide recommended feed levels of valine for weaned piglets, growing pigs, gilts, lactating sows, barrows and entire males. The summarized valine nutrient requirements for pigs at different stages offer valuable insights for future research and practical applications in animal husbandry.展开更多

Br.) is the Sahelian crop par excellence due to its adaptation to the particular production conditions in this region. Unfortunately, in recent years this crop has been threatened by very strong parasitic pressure and drought during the production period. The objective of this study is to analyze the main constraints of millet production and the solutions known to producers. A survey was carried out in November 2022 with a sample of 298 producers in five municipalities in the Tahoua region. The main constraints are drought and pressure from crop pests (locust, millet ear miner, floricultural insects) according to 57.9% of respondents. The millet ear miner is the most formidable pest according to 55% of respondents. Thus, the average yield obtained in a year of good production without the leafminer is 194 kg/ha and that obtained in a year of millet ear leafminer is around 27 kg to 43 kg/ha depending on the municipality. The yield obtained this last campaign after the attack of this leafminer varies from 64 to 77 kg/ha depending on the municipalities compared to a potential yield of over 1000 kg/ha. More than half of producers (58.1%) are unaware of the existence of biological control compared to only 12.5% who are aware of this alternative method. Work to popularize this technology is necessary in the five municipalities and the entire region in general.展开更多

Although the technology is now mature, there is currently the problem of the availability of contrast agents to be injected IV. The aim of this methodology article is to propose an alternative solution to the need for contrast agents for clinical research, particularly in oncology. Methodology: They consist of coupling a fluorescent marker in the form of an NHS derivative, such as IR DYE manufactured in compliance with GMP, with therapeutic monoclonal antibodies having marketing authorization for molecular imaging. For a given antibody, the marking procedure must be the subject of a validation file on the final preparation filtered on a sterilizing membrane at 0.22 μm. Once the procedure has been validated, it would be unnecessary to repeat the tests before each clinical research examination. A check of the marking by thin-layer chromatography (TLC) and place it in a sample bank at +4˚C for 1 month of each injected formulation would be sufficient for additional tests if necessary. Conclusion: Molecular near-infrared fluorescence imaging is experiencing development, the process of which could be accelerated by greater availability of clinical contrast agents. Alternative solutions are therefore necessary to promote clinical research in this area. These methods must be shared to make it easier for researchers.展开更多

No significant difference was found between placebo and biological agents regarding their safety.CONCLUSION: All biological agents were superior to placebo for UC treatment in both induction and maintenance phases with a similar safety profile, and infliximab had a better clinical effect than the other biological agents.
文摘Erwinia amylovora species were isolated from the blossoms, exudates, infected fruits, leaves and bent branches of diseased apple, pear and hawthorn trees, selected in the Chy, Osh and Jalal Abad regions. Biochemical and pathogenicity tests, alongside PCR analyses, were conducted to identify the local isolates of Erwinia amylovora. The alternative antagonistic microorganisms which combat bacterium E. amylovora were tested within in vitro and in vivo conditions. The results revealed the ability of Streptomyces antagonistic bacteria to decrease fire blight severity on pear and apple trees during the first stage of the fire blight disease in leaf tissues. Streptomyces strain C1-4 suppressed E. amylovora disease symptoms in the leaf tissues and excised apple and pear shoots. The incidence of fire blight on leaves was reduced by about 70% with two applications of bacterial antagonists. Further studies at different locations in Kyrgyzstan, using large scale application, would allow for stronger recommendations to be made, including studies and recommendations on their ability to prevent disease and to use them as main components in an integrated pest management program.

文摘The experiment on control of Lymantria dispar L by using different kinds of biological measures, including nuclear polyhedrosis virus (NPV) of Lymantria dispar L., BtMP-342, sex-attractant as well as botanical insecticide, was carried out in the forest regions of Inner Mongolia in 2003. Two concentrations (2.632×10^6 PIB·ml^-1 and 2.632×10^7 PIB·ml^-1) of Lymantria dispar L. NPV were sprayed on the 2rd-instar-larvae of L. dispar and 70% and 77.8% control effect were obtained respectively. BtMP0-342 was applied to the 3rd- and 4th-instar larvae and the control effect was around 80%. The sex-attractant provided by Canada Pacific Forestry Research Center also showed a good result in trapping L. dispar adults. The self-produced botanical insecticide, which was extracted from a kind of poisonous plant distributed in Daxing'an Mountains, China, exhibited a good control result in controlling the larvae of L. dispar, and 82% mortality was observed when spraying primary liquid of the botanical insecticide on the 3rd-5th-instar-larvae in lab.
文摘In the past,there has been considerable focus on a host of drugs and chemicals that may produce colonic toxicity.Now,a variety of new biological monoclonal antibody agents,usually administered by infusion,have appeared in the clinical realm over the last decade or so to treat different chronic inflammatory or malignant disorders.For some of these agents,adverse effects have been documented,including apparently new forms of immune-mediated inflammatory bowel disease.In some,only limited symptoms have been recorded,but in others,severe colitis with serious complications,such as bowel perforation has been recorded.In others,adverse effects may have a direct vascular or ischemic basis,while other intestinal effects may be related to a superimposed infection.Some new onset cases of ulcerative colitis or Crohn's disease may also be attributed to the same agents used to treat these diseases,or be responsible for disease exacerbation.Dramatic and well documented side effects have been observed with ipilimumab,a humanized monoclonal antibody developed to reduce and overcome cytotoxic T-lymphocyte antigen 4,a key negative feedback regulator of the T-cell anti-tumor response.This agent has frequently been used in the treatment of different malignancies,notably,malignant melanoma.Side effects with this agent occur in up to 40% and these are believed to be largely immune-mediated.One of these is a form of enterocolitis that may be severe,and occa-sionally,fatal.Other agents include rituximab(an antiCD20 monoclonal antibody),bevacizumab(a monoclonal antibody against the vascular endothelial growth factor) and anti-tumor necrosis factor agents,including infliximab,adalimumab and etanercept.

文摘Drip irrigation of biological agents is an important green pathway to prevent diseases in Xinjiang cotton fields, especially soil-borne diseases. In order to clear the suitable dosage of different biological agents for controlling cotton Verticillium wilt, field split plot experiment was designed to research the control effects of Bacillus subtilis WP (15, 30 and 45 kg/hm^2), Shibeijian Trichoderma harzianum (15, 18 and 24 kg/hm^2), Yufeng“99”(15, 22.5 and 30 kg/hm^2), Zhongnonglukang (30, 45 and 60 kg/hm^2) and Athomin (45, 60 and 75 kg/hm^2) on cotton Vertillium wilt in 2016 and 2017. The disease control effect against cotton Verticillium wilt, cotton growth, cotton yield and fiber quality were compared and analyzed by biometrical method. The results showed that five biological agents significantly reduced the incidence rate and disease index of cotton Verticillium wilt, and the average control effect reached 33.50%-74.94%. The control effect of Shibeijian T. harzianum dripped at the dosage of 18 kg/hm^2 was significantly higher than that dripped at 15 and 24 kg/hm^2. There was no significant difference between different application dosages in Athomin treatment. The control effect of the remaining three agents had significantly positive correlation with application dosage. Five biological agents had obvious promotion effects on cotton growth, and the cotton height, width of the top fourth leaf, fruit branch number and boll number per plant were increased in different levels. The cotton height and width of the top fourth leaf had no obvious changes with the increase of dosage, while the fruit branch number and boll number increased with the increasing dosage. Meanwhile, these biological agents significantly advanced the maturity of cotton. Except for Athomin treatment, the cotton seed yield in other treatments showed an increasing trend and increased significantly with the increasing dosage. The cotton fiber length and fiber breaking tenacity were improved slightly, but cotton quality had not been improved conspicuously. Therefore, according to disease control effect, cotton growth and yield performance, the suitable drip dosage of biological agents were as follows: Yufeng "99" 30 kg/hm^2, Zhongnonglukang 60 kg/hm^2, B. subtilis WP 45.0 kg/hm^2, and Shibejian T. harzianum 18.0 kg/hm^2. The drip dosage of Athomin still needs to be further studied.

文摘Because inflammation plays a key role in the pathogenesis of dry eye disease and Sjogren's syndrome, topical anti-inflammatory agents such as corticosteroids and cyclosporine A have been used to treat inflammation of the ocular surface and lacrimal gland. Systemic biological agents that target specific immune molecules or cells such as tumor necrosis factor(TNF)-α, interferone-α, interleukin(IL)-1, IL-6, or B cells have been used in an attempt to treat Sjogren's syndrome. However, the efficacy of systemic biological agents, other than B-cell targeting agents, has not yet been confirmed in Sjogren's syndrome. Several studies have recently evaluated the efficacy of topical administration of biological agents targeting cytokines in the treatment of dry eye disease. Topical blockade of IL-1 by using IL-1 receptor antagonist could ameliorate clinical signs and inflammation of experimental dry eye. Using a mouse model of desiccating stress-induced dry eye, we have demonstrated that topical application of a TNF-α blocking agent, infliximab, could improve tear production and ocular surface irregularity, decrease inflammatory cytokines and Th-1 CD4+ cells on the ocular surface, and increase gobletcell density in the conjunctiva. Although controversy still remains, the use of topical biological agents targeting inflammatory cytokines may be a promising therapy for human dry eye disease.

文摘This study was conducted to explore and seek high-efficiency and safe green control techniques on sugarcane borers,promote green control of diseases and pests of sugarcane and build a resource-conserving,environmentally friendly and sustainable governance system of diseases and pests of sugarcane.A new sex pheromone trap of sugarcane borers,abamectin· Bacillus thuringiensis (Bt) and tebufenozide were selected and applied in field trials.The use of the new sex pheromone trap of sugarcane borers (6 traps/hm 2) in combination with 0.05% abamectin·10 billion active gemmae/g B.thuringiensis (Bt) WP (1.8 kg/hm 2) or new sex pheromone trap of sugarcane borers (6 traps/hm 2) in combination with 200 g/L tebufenozide SC (1.5 L/hm 2) were the best in the sugarcane production.New sex pheromone trap of sugarcane borers should be installed in early march,and biological agents were mixed with water 900 kg per hectare and sprayed evenly sugarcane plants at the beginning of April.Their control effects of dead heart rate and bored stalk rate could be more than 69.98% and 49.09%,respectively,which were superior to that of the control pesticide 3.6% bisultap GR (90 kg/hm 2).The results showed that new sex pheromone trap of sugarcane borers in combination with abamectin· B.thuringiensis (Bt) or tebufenozide was the optimum mode of green control techniques on sugarcane borers.When it was alternately or coordinately used with other technology,it could delay the emergence and development of drug resistance,and it was worthy of widespread popularization and application in sugarcane area.
文摘Among the most economically important fruit crops in South and North Kyrgyzstan affected by scab disease are apples (Malus domestica). Natural isolates of Venturia inaequalis were isolated from diseased parts of apple trees, selected from different regions, through sedimentation of air microflora on the crowns of fruit trees. Two biocontrol agents as Trichoderma viride and Streptomyces sр. were tested for apple scab control in vitro and field conditions. Two applications of Trichoderma viride within 35 days completely stopped the scab disease in seedling leaves. Within 40 days, the seedlings were recovered;the new leaves have blossomed on branches. The Streptomyces sp. antagonists were inferior in effectiveness compared to Trichoderma viride;nevertheless, they prevented progression of the disease in the leaves. Seedlings grew new shoots and leaves around 50 days after the second treatment. Orchard experiment results provide great hope that a biological product based on Trichoderma viride could work as an effective agent to suppress the development of the pathogen in the early spring, when leaves start to show scab disease symptoms.
文摘Inflammatory uveitis is a difficult condition to treat. Recently, a new class of drugs obtained by a biological process and therefore defined as “biologics” has been successfully used in the treatment of immunemediated rheumatic diseases. These drugs target different pro-inflammatory cytokines including tumor necrosis factor-α, interleukin-1 and interleukin-6, or immune effector cells including B and T lymphocytes. Their use has been then extended to different forms of uveitis resistant to standard therapy in small uncontrolled trials, with general and unexpected efficacy. The present review analyzes the literature on treatment of uveitis with the biologics currently available for the treatment of inflammatory rheumatic diseases. We used PubMed search engine as the main source of information. Among the papers included in the reference list, a particular emphasis was given on articles published during the last 5 years.

文摘Immunoglobulin A nephropathy(IgAN)is the most common primary glomerular disease,and the“four-hit”theory represents its currently accepted pathogenic mechanism.Mucosal immunity triggered by infections in the respiratory tract,intestines,or other areas leads to antigen presentation,T cell stimulation,B cell maturation,and the production of IgA-producing plasma cells.The proteins B-lymphocyte stimulator(BLyS)and a proliferation-inducing ligand(APRIL)are involved in this process,and alternative complement and lectin pathway activation are also part of the pathogenic mechanism.Kidney Disease Improving Global Outcomes guidelines indicate that a specific effective treatment for IgAN is lacking,with renin-angiotensin-aldosterone system inhibitors being the primary therapy.Recent research shows that biological agents can significantly reduce proteinuria,stabilize the estimated glomerular filtration rate,and reverse some pathological changes,such as endocapillary proliferation and crescent formation.There are four main categories of biological agents used to treat IgA nephropathy,specifically anti-CD20 monoclonal antibodies,anti-BLyS or APRIL monoclonal antibodies,monoclonal antibodies targeting both BLyS and APRIL(telitacicept and atacicept),and monoclonal antibodies inhibiting complement system activation(narsoplimab and eculizumab).However,further research on the dosages,treatment duration,long-term efficacy,and safety of these biological agents is required.
文摘Nanotechnology is the new hope, and is hailed as having the potential to increase the efficiency of energy consumption, help clean the environment, and solve major health problems. This research aims to increase the biological activities of natural syringaldehyde. The synthesis of syringaldehyde derivatives and controls the size of the material particles in the nanometer ranges. Nano-organic compounds (L1 - L2) and nano-organometallic compounds (C1 - C4) are used for the study of physicochemical characterization and biological activities. Antioxidant capacities were the DPPH and FRAP techniques, and bacterial abilities against Escherichia coli, Salmonella spp. and Staphylococcus aureus. The syringaldehyde salicylic hydrazone (L2) showed a high scavenging ability to DPPH. Free radical exhibited with IC<sub>50</sub> values as low as 51.109 ppm. The ability of antioxidants by FRAP showed that substances are capable of reducing Fe<sup>3+</sup> and most of C3, the ability to inhibit the growth of bacteria with the lowest MIC and MBC values and the ability to Chilo polychrysus (Meyrick) found that C1 and C2 showed LT<sub>50</sub> at 24 h and 48 h (19.00 and 19.33). These particles should develop as biological agents to reduce the use of chemicals that are harmful to humans and the environment.

文摘Valine is an essential amino acid and a type of branched-chain amino acid. Due to the involvement of branchedchain amino acids in various metabolic pathways, there has been a surge of interests in valine nutrition and its role in animal physiology. In pigs, the interactions between valine and other branched-chain amino acids or aromatic amino acids are complex. In this review, we delve into the interaction mechanism, metabolic pathways, and biological functions of valine. Appropriate valine supplementation not only enhances growth and reproductive performances, but also modulates gut microbiota and immune functions. Based on past observations and interpretations, we provide recommended feed levels of valine for weaned piglets, growing pigs, gilts, lactating sows, barrows and entire males. The summarized valine nutrient requirements for pigs at different stages offer valuable insights for future research and practical applications in animal husbandry.

文摘White Hypsizygus marmoreus is a popular edible mushroom.Its mycelium is easy to be contaminated by Penicillium,which leads to a decrease in its quality and yield.Penicillium could compete for limited space and nutrients through rapid growth and produce a variety of harmful gases,such as benzene,aldehydes,phenols,etc.,to inhibit the growth of H.marmoreus mycelium.A series of changes occurred in H.marmoreus proteome after contamination when detected by the label-free tandem mass spectrometry(MS/MS)technique.Some proteins with up-regulated expression worked together to participate in some processes,such as the non-toxic transformation of harmful gases,glutathione metabolism,histone modification,nucleotide excision repair,clearing misfolded proteins,and synthesizing glutamine,which were mainly used in response to biological stress.The proteins with down-regulated expression are mainly related to the processes of ribosome function,protein processing,spliceosome,carbon metabolism,glycolysis,and gluconeogenesis.The reduction in the function of these proteins affected the production of the cell components,which might be an adjustment to adapt to growth retardation.This study further enhanced the understanding of the biological stress response and the growth restriction adaptation mechanisms in edible fungi.It also provided a theoretical basis for protein function exploration and edible mushroom food safety research.

文摘Millet (Pennisetum glaucum (L.) R. Br.) is the Sahelian crop par excellence due to its adaptation to the particular production conditions in this region. Unfortunately, in recent years this crop has been threatened by very strong parasitic pressure and drought during the production period. The objective of this study is to analyze the main constraints of millet production and the solutions known to producers. A survey was carried out in November 2022 with a sample of 298 producers in five municipalities in the Tahoua region. The main constraints are drought and pressure from crop pests (locust, millet ear miner, floricultural insects) according to 57.9% of respondents. The millet ear miner is the most formidable pest according to 55% of respondents. Thus, the average yield obtained in a year of good production without the leafminer is 194 kg/ha and that obtained in a year of millet ear leafminer is around 27 kg to 43 kg/ha depending on the municipality. The yield obtained this last campaign after the attack of this leafminer varies from 64 to 77 kg/ha depending on the municipalities compared to a potential yield of over 1000 kg/ha. More than half of producers (58.1%) are unaware of the existence of biological control compared to only 12.5% who are aware of this alternative method. Work to popularize this technology is necessary in the five municipalities and the entire region in general.

文摘Biological nitrification inhibitors(BNIs)are released from plant roots and inhibit the nitrification activity of microorganisms in soils,reducing NO_(3)^(‒)leaching and N2O emissions,and increasing nitrogenuse efficiency(NUE).Several recent studies have focused on the identification of new BNIs,yet little is known about the genetic loci that govern their biosynthesis and secretion.We applied a combined transcriptomic and metabolomic analysis to investigate possible biosynthetic pathways and transporters involved in the biosynthesis and release of BNI 1,9-decanediol(1,9-D),which was previously identified in rice root exudates.Our results linked four fatty acids,icosapentaenoic acid,linoleate,norlinolenic acid,and polyhydroxy-α,ω-divarboxylic acid,with 1,9-D biosynthesis and three transporter families,namely the ATP-binding cassette protein family,the multidrug and toxic compound extrusion family,and the major facilitator superfamily,with 1,9-D release from roots into the soil medium.Our finding provided candidates for further work on the genes implicated in the biosynthesis and secretion of 1,9-D and pinpoint genetic loci for crop breeding to improve NUE by enhancing 1,9-D secretion,with the potential to reduce NO_(3)^(‒)leaching and N2O emissions from agricultural soils.
文摘Introduction: Near-infrared fluorescence imaging is a technique that will establish itself in the short term at the international level because it is recognized for its potential to improve the performance of surgical interventions, its moderate investment and operating costs and its portability. Although the technology is now mature, there is currently the problem of the availability of contrast agents to be injected IV. The aim of this methodology article is to propose an alternative solution to the need for contrast agents for clinical research, particularly in oncology. Methodology: They consist of coupling a fluorescent marker in the form of an NHS derivative, such as IR DYE manufactured in compliance with GMP, with therapeutic monoclonal antibodies having marketing authorization for molecular imaging. For a given antibody, the marking procedure must be the subject of a validation file on the final preparation filtered on a sterilizing membrane at 0.22 μm. Once the procedure has been validated, it would be unnecessary to repeat the tests before each clinical research examination. A check of the marking by thin-layer chromatography (TLC) and place it in a sample bank at +4˚C for 1 month of each injected formulation would be sufficient for additional tests if necessary. Conclusion: Molecular near-infrared fluorescence imaging is experiencing development, the process of which could be accelerated by greater availability of clinical contrast agents. Alternative solutions are therefore necessary to promote clinical research in this area. These methods must be shared to make it easier for researchers.

文摘Background Physical entity interactions in mixed reality(MR)environments aim to harness human capabilities in manipulating physical objects,thereby enhancing virtual environment(VEs)functionality.In MR,a common strategy is to use virtual agents as substitutes for physical entities,balancing interaction efficiency with environmental immersion.However,the impact of virtual agent size and form on interaction performance remains unclear.Methods Two experiments were conducted to explore how virtual agent size and form affect interaction performance,immersion,and preference in MR environments.The first experiment assessed five virtual agent sizes(25%,50%,75%,100%,and 125%of physical size).The second experiment tested four types of frames(no frame,consistent frame,half frame,and surrounding frame)across all agent sizes.Participants,utilizing a head mounted display,performed tasks involving moving cups,typing words,and using a mouse.They completed questionnaires assessing aspects such as the virtual environment effects,interaction effects,collision concerns,and preferences.Results Results from the first experiment revealed that agents matching physical object size produced the best overall performance.The second experiment demonstrated that consistent framing notably enhances interaction accuracy and speed but reduces immersion.To balance efficiency and immersion,frameless agents matching physical object sizes were deemed optimal.Conclusions Virtual agents matching physical entity sizes enhance user experience and interaction performance.Conversely,familiar frames from 2D interfaces detrimentally affect interaction and immersion in virtual spaces.This study provides valuable insights for the future development of MR systems.

文摘Na^(+)/K^(+)-ATPase is a transmembrane protein that has important roles in the maintenance of electrochemical gradients across cell membranes by transporting three Na^(+)out of and two K^(+)into cells.Additionally,Na^(+)/K^(+)-ATPase participates in Ca^(2+)-signaling transduction and neurotransmitter release by coordinating the ion concentration gradient across the cell membrane.Na^(+)/K^(+)-ATPase works synergistically with multiple ion channels in the cell membrane to form a dynamic network of ion homeostatic regulation and affects cellular communication by regulating chemical signals and the ion balance among different types of cells.Therefo re,it is not surprising that Na^(+)/K^(+)-ATPase dysfunction has emerged as a risk factor for a variety of neurological diseases.However,published studies have so far only elucidated the important roles of Na^(+)/K^(+)-ATPase dysfunction in disease development,and we are lacking detailed mechanisms to clarify how Na^(+)/K^(+)-ATPase affects cell function.Our recent studies revealed that membrane loss of Na^(+)/K^(+)-ATPase is a key mechanism in many neurological disorders,particularly stroke and Parkinson's disease.Stabilization of plasma membrane Na^(+)/K^(+)-ATPase with an antibody is a novel strategy to treat these diseases.For this reason,Na^(+)/K^(+)-ATPase acts not only as a simple ion pump but also as a sensor/regulator or cytoprotective protein,participating in signal transduction such as neuronal autophagy and apoptosis,and glial cell migration.Thus,the present review attempts to summarize the novel biological functions of Na^(+)/K^(+)-ATPase and Na^(+)/K^(+)-ATPase-related pathogenesis.The potential for novel strategies to treat Na^(+)/K^(+)-ATPase-related brain diseases will also be discussed.
