Improved bioavailability and pharmacokinetics of tea polyphenols by encapsulation into gelatin nanoparticles.

The authors prepared surface modified (with polyelectrolyte layers), tea polyphenols (TPP) encapsulated, gelatin nanoparticles (TPP-GNP) and characterised them. The size of the spherical nanoparticles was ∼50 nm. Number of polyelectrolyte layers and incubation time influenced the encapsulation efficiency (EE); highest EE was noted in nanoparticles with six polyelectrolyte layers (TPP-GNP-6L) incubated for 4 h.

Positive regulation of biochemical parameters by tea polyphenol encapsulated solid lipid nanoparticles at and conditions.

Tea polyphenols (TPPs) comprise preventive and therapeutic potentials against cancer, cardiovascular and neurological disorders. Chemical instability of TPP which leads to low bioavailability is the major constrain to its use as therapeutic agent. The authors prepared TPP encapsulated solid lipid nanoparticles (TPP-SLNs) to increase its stability and bioefficacy.

Identification of evolutionarily conserved Momordica charantia microRNAs using computational approach and its utility in phylogeny analysis.

Momordica charantia (bitter gourd, bitter melon) is a monoecious Cucurbitaceae with anti-oxidant, anti-microbial, anti-viral and anti-diabetic potential. Molecular studies on this economically valuable plant are very essential to understand its phylogeny and evolution. MicroRNAs (miRNAs) are conserved, small, non-coding RNA with ability to regulate gene expression by bind the 3' UTR region of target mRNA and are evolved at different rates in different plant species.

Role of microRNA 21 in mesenchymal stem cell (MSC) differentiation: a powerful biomarker in MSCs derived cells.

The significant role of microRNAs (miRNAs) in stem cell development has been expansively discussed in recent publications and they are noticed to be involved in post transcriptional regulation of gene expression by its affinity towards the 3'UTR of target mRNA. Since the expression of miR-21 was high in cells that were derived from MSCs, recent evidence indicates that miR-21 plays a vital role in mesenchymal stem cells (MSCs) differentiation. Despite the fact that miR-21 can be considered as a powerful biomarker for MSCs differentiation, the number of studies related to the above scenario is very limited.
