    Biodegradable Materials as Nanocarriers for Drugs and Nutrients

    Xingran Kou1,2, Qixuan Zhao2, Wenwen Xu2, Zuobing Xiao2, Yunwei Niu2, Kai Wang3,*

    Journal of Renewable Materials, Vol.9, No.7, pp. 1189-1211, 2021, DOI:10.32604/jrm.2021.015268

    Abstract Several important drugs and nutritional supplements are limited by their lack of bioavailability. Nanomaterials display unique beneficial properties that might help improve the bioavailability of drugs and nutritional supplements. Unfortunately, nanomaterials produced from synthetic polymers and metals may have similar difficulties with bioavailability and toxicity. Naturally occurring biopolymers are biodegradable and non-toxic and are adaptable to the synthesis of nanoparticles. Drugs and other substances can be encapsulated or embedded in such particles with an increase in bioavailability. The search for biodegradable nanomaterials is an active research field. This review summarizes the research on nanocrystalline cellulose, starch, lignin, and other biological… More >

    Muhammad Zafar-ul-Hye1,*, Misbah Batool Zahra1, Subhan Danish1, Mazhar Abbas2, Abdur Rehim1, Muhammad Naeem Akbar1, Ayesha Iftikhar1, Mehreen Gul1, Ifat Nazir1, Maria Abid1, Muhammad Tahzeeb-ul-Hassan1, Maria Murtaza3

    Phyton-International Journal of Experimental Botany, Vol.89, No.2, pp. 405-413, 2020, DOI:10.32604/phyton.2020.08918

    Abstract Rhizosphere bacteria that colonize plant roots and confer beneficial effects are referred as plant growth promoting rhizobacteria (PGPR). Among all PGPR, some rhizobacteria have an ability to produce ACC deaminase enzyme. This enzyme catalyzes stress ACC into a-ketobutyrate and ammonia instead of letting it to be converted to ethylene. Ethylene level rises in plants under stress conditions i.e., drought, salinity, poor soil fertility etc. As poor soil fertility is a big hurdle to achieve the optimum yield of crops, inoculation of ACC deaminase PGPR can overcome this problem to some extent. The aim of the current study was to examine… More >

    Phyton-International Journal of Experimental Botany, Vol.88, No.4, pp. 435-448, 2019, DOI:10.32604/phyton.2019.07512

    Abstract Canola and oat forage potential may be affected by climatic conditions when sown early. The objective of this study was to evaluate the forage canola and oat potential in four early sowing dates (September 11 and 25; October 9 and 23) during the 2012-2013 and 2013-2014 cycles in Matamoros, Coahuila, Mexico. Growth cycle duration, chemical composition, dry matter (DM), crude protein (CP), and net energy for lactation (NEL) yields were determined. High temperatures and long photoperiods affected crops seeded on September 11, accelerating growth and reducing canola (26.6%-31.7%) and oat (15.8%) DM yields. As of September 25, canola cv IMC… More >
