Plant Virus Nanoparticles for Anti-cancer Therapy.

Plant virus nanoparticles (VNPs) are inexpensive to produce, safe, biodegradable and efficacious as treatments. The applications of r plant virus nanoparticles range from epitope carriers for vaccines to agents in cancer immunotherapy. Both VNPs and virus-like particles (VLPs) are highly immunogenic and are readily phagocytosed by antigen presenting cells (APCs), which in turn elicit antigen processing and display of pathogenic epitopes on their surfaces.

Frontiers in Bioengineering and Biotechnology: Plant Nanoparticles for Anti-Cancer Therapy.

Naturally occurring viral nanomaterials have gained popularity owing to their biocompatible and biodegradable nature. Plant virus nanoparticles (VNPs) can be used as nanocarriers for a number of biomedical applications. Plant VNPs are inexpensive to produce, safe to administer and efficacious as treatments.

Evaluation of efficient carbon, nitrogen sources, micro and macro nutrients for dextran production by Weissella cibaria CMGDEX3 by utilizing a modified multifactorial Placket-Burman statistical design.

In the present study previously isolated Weissella cibaria CMG DEX3 capable of producing high molecular weight, water soluble dextran (Ahmed et al., 2012) is characterized for most efficient less expensive carbon, nitrogen sources, micro and macro nutrients by utilizing a multifactorial Placket-Burman statistical design for optimization of dextran production. A twelve run Plackett-Burman experimental model with slight modification was utilized to evaluate the impact of ten diverse nutrients on the production of dextran by the bacterial isolate Weissella cibaria CMG DEX3.

An Inside Look into Biological Miniatures: Molecular Mechanisms of Viroids.

Viroids are tiny single-stranded circular RNA pathogens that infect plants. Viroids do not encode any proteins, yet cause an assortment of symptoms. The following review describes viroid classification, molecular biology and spread.

Cytogenetic investigation of couples with recurrent spontaneous miscarriages.

Background & Objective: Spontaneous pregnancy loss has always been the frustrating experience for the couples and concern clinician. Chromosomal abnormality in either of the parent is considered to be the one of the leading cause of recurrent spontaneous miscarriages. This study was designed to evaluate the possible chromosomal etiology of miscarriage and the subsequent intimacy of maternal or paternal genetic abnormality.

Future of cancer immunotherapy using plant virus-based nanoparticles.

Immunotherapy potentiates a patient's immune response against some forms of cancer, including malignant tumors. In this Special Report, we have summarized the use of nanoparticles that have been designed for use in cancer immunotherapy with particular emphasis on plant viruses. Plant virus-based nanoparticles are an ideal choice for therapeutic applications, as these nanoparticles are not only capable of targeting the desired cells but also of being safely delivered to the body without posing any threat of infection.

Horizontal gene transfer of stress resistance genes through plasmid transport.

The horizontal gene transfer of plasmid-determined stress tolerance was achieved under lab conditions. Bacterial isolates, Enterobacter cloacae (DGE50) and Escherichia coli (DGE57) were used throughout the study. Samples were collected from contaminated marine water and soil to isolate bacterial strains having tolerance against heavy metals and antimicrobial agents.
