Due to the reg.lation of the river Volg. flow, expanding.of the territories intended for construction and development of ag.iculture wetlands Volg.-Akhtuba floodplain are being.sig.ificantly.transformed and are losing.many.of their qualities. Non-reg.lated loads lead to the break of natural phy.ical and chemical characteristics of water bodies, loss of biodiversity. deg.adation of structure and functions of biolog.cal communities and, as a result, to decreasing.of potential ecosy.tem services. Restoration of the lost qualities of water ecosy.tems is a key.factor in increasing.sustainability.of reclaimed landscapes and creating.comfortable conditions for living.of locals and their economic activity. On the territory.of the biosphere reserve “Nature park” “Volg.-Akhtuba floodplain” a number of model sites were defined in order for research projects and practical work on restoration of deg.aded landscapes to be executed. The widest rang. of the lost ecosy.tem qualities is being.restored during.work on Lake Zapornoy.. Restoration of ecosy.tem functions is being.implemented according.to the main economic activities carried out in this area. Ecosy.tem services of the area are specified in accordance with its functional purpose. The existing.landscape and ecolog. conditions have been studied and estimated to see if the planned ecosy.tem services can be provided. The project sug.ests the following.activities: restoration of hy.ro-morpholog.cal characteristics, reconstruction of habitats for biodiversity.and their ecosy.tem services, improvement to restore and preserve recreational qualities of landscape. The project includes the monitoring.the effectiveness of restoration. Monitoring.prog.am is based on indices of environmental assessment.

Exosomes, a specialised ty.e of extracellular vesicle, have attracted sig.ificant attention in the realm of tendon/lig.ment repair as a potential biolog.c therapeutic tool. While the competence of key.substances responsible for the delivery.function was g.adually.elucidated, series of shortcoming. exemplified by.the limited stability.still need to be improved. Therefore, how to take maximum advantag. of the biolog.cal characteristics of exosomes is of g.eat importance. Recently. the comprehensive exploration and application of biomedical eng.neering.has improved the availability.of exosomes and revealed the future direction of exosomes combined with biomaterials. This review delves into the present application of biomaterials such as nanomaterials, hy.rog.ls, and electrospun scaffolds, serving.as the carriers of exosomes in tendon/lig.ment repair. By.pinpointing.and exploring.their streng.hs and limitations, it offers valuable insig.ts, paving.the way.the future direction of biomaterials in the application of exosomes in tendon/ lig.ment repair in this field. © 2024, Chinese Medical Multimedia Press Co Ltd.

“y.n-y.ng.philosophy. for the desig. of anticancer drug.delivery.nanoparticles

Biomaterials Translational 2024年第2期5卷 144-156页

作者： Ai y. Tian y. Qiao J. Wang.C. Li H. School of Lifesciences Shanghai University Shanghai China

Understanding.the in vivo transport process provides g.idelines for desig.ing.ideal nanoparticles (NPs) with hig.er efficacy.and fewer off-targ.t effects. Many.factors, such as particle size, morpholog., surface potential, structural stability. and etc., may.influence the delivering.process of NPs due to the existence of various phy.iolog.cal barriers within the body. Herein, we summarise the distinct influences of NP phy.icochemical properties on the four consecutive in vivo transport steps: (1) navig.ting.with bloodstream within blood vessels, (2) transport across vasculature walls into tumour tissues, (3) intratumoural transport throug. the interstitial space, and (4) cellular uptake & intracellular delivery.by.cancerous cells. We found that the philosophy.behind the current consensus for NP desig. has certain similarities to the “y.n-y.ng. theory.in traditional Chinese culture. Almost all phy.icochemical properties, reg.rdless of big.or small sizes, long.or short leng.h, positive or neg.tive zeta potentials, are double-edg.d swords. The balance of potential benefits and side effects, drug.selectivity.and accessibility.should be fully.considered when optimising.particle desig., similar to the “y.n-y.ng.harmony.. This paper presents a comprehensive review of the advancements in NPs research, focusing.on their distinct features in tumour targ.ting. drug.delivery. and cell uptake. Additionally. it deliberates on future developmental trends and potential obstacles, thereby.aiming.to uncover the way. these characteristics influence the NPs’ biolog.cal activity.and provide theoretical g.idance for the targ.ted delivery.of NPs. © 2024, Chinese Medical Multimedia Press Co Ltd.

Ag.iculture has play.d an important role in the g.owth of the Indian economy. Water and electricity.are essential inputs for ag.iculture today. India produces the third-larg.st amount of electricity.in the world, behind China and the USA. As an incentive to increase production, most states provide free electricity.to farmers. Free electricity.has decreased g.oundwater levels and increased electricity.consumption. The objective of this study.was to find out the factors that influenced farmers to adopt a solar water-pumping.sy.tem in g.jarat. The samples were randomly.selected. This study.examined the entire state of g.jarat. One hundred and fifty.farmers who adopted solar water-pumping.sy.tems were interviewed, including.50 banana farmers, 50 cotton farmers and 50 g.oundnut farmers. Primary.data were collected throug. an interview. The adoption of solar water-pumping.sy.tems by.farmers was identified using.factor analy.is. SPSS software was used to analy.e the data collected. In this study. only.two factors contributed to the variance of 59.469%. The adoption of solar water pumps by.farmers was influenced by.g.vernment policy.and economic benefits. An economic benefit variance of 33.20% was found, while a g.vernment policy.variance was 26.27%. A solar water-pumping.sy.tem has low initial costs, flexible credit policies motivate adoption, solar water-pumping.sy.tems can save electricity. and maintenance and repair costs are affordable. g.vernment policy.that includes solar water-pumping.sy.tems is motivated by.awareness, subsidies for adoption and a fair price to sell energ. surpluses. Farmers are recommended to adopt a solar water-pumping.sy.tem in conjunction with a drip irrig.tion sy.tem to receive additional income. The successful scheme will be recommended to other states in India for implementation. The factors that influence farmers to adopt a solar water-pumping.sy.tem in g.jarat, India are identified based on interviews with one hundred and fifty.randomly.sel

中华神经外科杂志(英文) 2024年第3期10卷 1-3页

作者： Chong.Ji y. Jan Kalimullah Stroke Center New York Medical College Westchester Medical Center Valhalla NY USA Neurovascular Fellow New York Medical College Westchester Medical Center Valhalla NY USA

Rivaroxaban, a direct oral anticoag.lant, has proven efficacy.and safety.at its standard dose in the treatment and prevention of various vascular conditions. These include the treatment of venous thromboembolism and stroke prevention in non-valvular atrial fibrillation. A "very.low" vascular dose of rivaroxaban, when combined with low-dose aspirin, has been demonstrated to reduce major adverse cardiovascular events, including.stroke, in both acute and chronic coronary.sy.drome. The combination of rivaroxaban and low-dose aspirin could potentially.offer an additional strateg. for stroke prevention in selected non-atrial fibrillation patients who are at a hig. risk of stroke.

Backg.ound The money.tree is a favored indoor potted plant in China. Its seeds resemble chestnuts in both shape and flavor when cooked, which are g.nerally.considered non-Toxic and safe for consumption. Case presentation This report presents the first published case of food poisoning.due to the ing.stion of larg. amounts of money.tree seeds. A 67-y.ar-old man exhibited toxic encephalopathy.sy.ptoms and dy.pnea after consuming.the seeds for approximately.6 months. After empirical mechanical ventilation, therapeutic plasma exchang., and other medical interventions, the patient's clinical status improved sig.ificantly. He was subsequently.discharg.d from the hospital. Conclusion Consuming.a substantial quantity.of money.tree seeds within a limited timeframe can lead to poisoning. resulting.in adverse outcomes, particularly.toxic encephalopathy. Moreover, plasma exchang. may.have some therapeutic effect. © Wolters Kluwer Health, Inc. All rig.ts reserved.
