With inevitable growth of demand for human and industrial needs, water available for agriculture will become scarcer in the future. India is a highly water-stressed country. Hence, India needs to invest in improving its water productivity, and any capacity to produce more rice with less water. System of Rice Intensification (SRI) has attracted much attention in increasing rice yield per unit area. For this study, fifteen farmers were selected those were practicing SRI technology by themselves during the Boro-cultivation season (January-April). The study was continued for three consecutive years 2012 to 14 on the same fields. In addition to the SRI plots, a similar size of non-SRI plot was maintained in conventional cultivation for comparison purpose. On an average, the non-SRI ight increased by 12%, number of tillers per square meter by 85%, number of reproductive tillers per hill by 286%, weight of panicle per hill by 139%, number of seeds per panicle by 41% and test weight by 26% due to SRI practice over the non-SRI practice. Average increment in straw and grain yield due to SRI over the non-SRI is 70% and 59% respectively. The physico-chemical and biological properties of soil improved due to SRI practice.

In agricultural systems, allelopathy can be part of the interference between crops and between crops and weeds through soil mediated mechanism and thereby affecting the economical outcome of the plant production. Allelopathic influence of various concentrations of aqueous extracts of two weed species ie.Cyperusrotundus L. and Cynodan dactylon L. were assessed on physico-chemical and biological properties of rice seedlings grown experimental pot soil. The results revealed that the percentage of NPK levels was minimum in the lower concentrations of two weed extracts than their higher concentration. Among NPKcontents, the nitrogen was found higher percentage followed by potassium and phosphorus in all the experimental soil. The population of bacterial, fungi, actinomycetes and total microbial populations were gradually decreased with increasing the concentration of weed extracts and more reduction on microbes wasfound in C.rotundus than C.dactylon applied soil

Regenerative medicine represents an emerging multidisciplinary field that brings together engineering methods and complexity of life sciences into a unified fundamental understanding of structure-property relationship in micro/nano environment to develop the next generation of scaffolds and hydrogels to restore or improve tissue functions. Chitosan has several unique physico-chemical properties that make it a highly desirable polysaccharide for various applications such as, biomedical, food, nutraceutical, agriculture, packaging, coating, etc. However, the utilization of chitosan in regenerative medicine is often limited due to its inadequate mechanical, barrier and thermal properties. Cellulosic nanomaterials (CNs), owing to their exceptional mechanical strength, ease of chemical modification, biocompatibility and favorable interaction with chitosan, represent an attractive candidate for the fabrication of chitosan/ CNs scaffolds and hydrogels. The unique mechanical and biological properties of the chitosan/CNs bio-nanocomposite make them a material of choice for the development of next generation bio-scaffolds and hydrogels for regenerative medicine applications. In this review, we have summarized the preparation method, mechanical properties, morphology, cytotoxicity/ biocompatibility of chitosan/CNs nanocomposites for regenerative medicine applications, which comprises tissue engineering and wound dressing applications.

Background: The therapeutic ability and application of antifungal peptide (APs) are limited by their physico-chemical and biological properties, the nano-liposomal encapsulation would improve the in vivo circulation and stability. </P><P> Objective: To develop a long-circulating liposomal delivery systems encapsulated APs-CGA-N12 with PEGylated lipids and cholesterol, and investigated through in vivo pharmacokinetics. Methods: The liposomes were prepared and characterized, a rapid and simple liquid chromatographytandem mass spectrometry (LC-MS/MS) assay was developed for the determination of antifungal peptide in vivo, the pharmacokinetic characteristics of APs liposomes were evaluated in rats. Results: Liposomes had a large, unilamellar structure, particle size and Zeta potential ranged from 160 to 185 nm and -0.55 to 1.1 mV, respectively. The results indicated that the plasma concentration of peptides in reference solutions rapidly declined after intravenous administration, whereas the liposomeencapsulated ones showed slower elimination. The AUC(0-∞) was increased by 3.0-fold in liposomes in comparison with standard solution (20 mg·kg-1), the half-life (T1/2) was 1.6- and 1.5-fold higher compared to the reference groups of 20 and 40 mg·kg-1, respectively. Conclusion: Therefore, it could be concluded that liposomal encapsulation effectively improved the bioavailability and pharmacokinetic property of antifungal peptides.

: The pace at which nanotheranostic technology for human disease is evolving has accelerated exponentially over the past five years. Nanotechnology is committed to utilizing the intrinsic properties of materials and structures at submicroscopic-scale measures. Indeed, there is generally a profound influence of reducing physical dimensions of particulates and devices on their physico-chemical characteristics, biological properties, and performance. The exploration of nature’s components to work effectively as nanoscaffolds or nanodevices represents a tremendous and growing interest in medicine for various applications (e.g., biosensing, tunable control and targeted drug release, tissue engineering). Several nanotheranostic approaches (i.e., diagnostic plus therapeutic using nanoscale) conferring unique features are constantly progressing and overcoming all the limitations of conventional medicines including specificity, efficacy, solubility, sensitivity, biodegradability, biocompatibility, stability, interactions at subcellular levels. : This review introduces two major aspects of nanotechnology as an innovative and challenging theranostic strategy or solution: (i) the most intriguing (bare and functionalized) nanomaterials with their respective advantages and drawbacks; (ii) the current and promising multifunctional “smart” nanodevices.
