Opis:: To improve crop yield, DNA technology has been used to enhance plant resistance toward pathogens and pests. Genes identified through understanding of host-pathogen interactions in viral, bacterial and fungal diseases, the mechanism of hypersensitive reaction in Arabidopsis and insect toxicity of natural peptides are used for their expression in plants. Progress on the use of simple sequence repeats (SSR) markers for resistance gene identification, development of virus-specific antibody gene expression in plants for virus control, construction of genes for multi-pathogen resistance, and use of viral vectors for gene efficiency evaluation are discussed.

Opis:: Military visible obscuration compositions (obscurants, smokes) play an important role on today’s battlefield. For many years, the known toxicity or ageing problems of established formulations were commonly accepted since there was a lack of alternatives. Since the U.S. Army stopped producing the AN-M8 hexachloroethane (HC) smoke grenade, the M83 terephthalic acid (TA) smoke grenade has been used in its place. This cool-burning, less toxic, but also low efficiency white smoke formulation cannot compete with HC-based formulations in terms of obscuration performance. In this context, we have explored the use of 5-aminotetrazole (5-AT) as an additive and fuel in the known TA system. Remarkably, it has been found that sugar is not necessarily required in the formulations, which has implications for the future improvement of sublimation-condensation smoke compositions, including coloured smoke compositions. In small-scale tests, it was found that replacing sucrose with 5-AT in the formulations resulted in significantly improved smoke persistence.

Opis:: Purpose Nucleolin is a multifactorial protein, having a significant role in chromatin remodelling, mRNA stability, ribosome biogenesis, stemness, angiogenesis, etc., thus, it is potential therapeutic target in cancer. The purpose of this paper is to study porous silicon (pSi) nanocarrier-based natural drug delivery system targeting dysregulated nucleolin expression for cancer therapeutics. Design/methodology/approach Quercetin was loaded in pre-synthesized and characterized pSi nanoparticles, and release kinetics was studied. The study compared the inhibitory concentration (IC50) of quercetin, synthetic drug doxorubicin, and quercetin-loaded pSi nanoparticles. Further, mRNA expression of a target gene, nucleolin, was tested with a quercetin treated breast cancer cell line (MCF-7). Findings Quercetin-loaded pSi nanoparticles followed first-order release kinetics. IC50 was determined at concentrations of 312 nM, 160 µM, and 50 µM against doxorubicin, quercetin, and quercetin-loaded pSi nanoparticles, respectively. The results further indicated 16-fold downregulation of nucleolin mRNA expression after 48h of quercetin treatment of exponentially growing MCF-7 cells. Research limitations/implications Whether pSi nanoparticle loaded quercetin can significantly downregulate nucleolin protein expression and its impact on apoptosis, cell proliferation, and angiogenic pathways need further investigation. Practical implications The practical application of the proposed nanocarrier-based drug delivery system potentially lays out a path for developing targeted therapy against nucleolin-dysregulated cancer using natural products to minimize the side effects of conventional chemotherapeutic drugs. Originality/value Inhibition of nucleolin and nucleolin regulated pathways using natural compounds and its targeted delivery with nanocarrier is not yet done.
