HER2 siRNA Facilitated Gene Silencing Coupled with Doxorubicin Delivery: A Dual Responsive Nanoplatform Abrogates Breast Cancer.

The present study investigated the concurrent delivery of antineoplastic drug, doxorubicin, and HER2 siRNA through a targeted theranostic metallic gold nanoparticle designed using polysaccharide, PSP001. The as-synthesized HsiRNA@PGD NPs were characterized in terms of structural, functional, physicochemical, and biological properties. HsiRNA@PGD NPs exposed adequate hydrodynamic size, considerable ζ potential, and excellent drug/siRNA loading and encapsulation efficiency.

Determinants of Patient Delay among Women with Carcinoma Breast.

Objective: The aim of the study was to estimate the delay in seeking treatment among women with carcinoma of breast and determine the factors associated with delay.

Methods: This was a hospital-based cross-sectional survey among 330 women attending the radiotherapy department of a tertiary care center in South India. Socio-clinical variables, duration of delay and reasons for the delay were collected by semi-structured interviews.

Electrospun polysaccharide scaffolds: wound healing and stem cell differentiation.

Irrespective of the labyrinth of fastidiously woven artificial scaffolds, the lack of biocompatibility hampers effective clinical translation, which is the definitive purpose of any biomedical system or device. Hence, the current exploration deals with the fabrication of scaffolds with enhanced bioactivities for wound healing. The methodology used for the fabrication of the scaffolds was electrospinning of the polysaccharide, which is isolated from tamarind seed kernel using the electrospinning process.

Doxorubicin eluting microporous polysaccharide scaffolds: An implantable device to expunge tumour.

A variety of naturally derived and synthetic biomaterial scaffolds have been investigated as 3D environments for supporting cell growth and can be used to achieve drug delivery with high loading efficiency. Polysaccharides which enhance the tumour-specific drug release are ideal candidates for scaffold preparation in combination with chemotherapeutic agents for the management of solid tumours by local applications. Galactoxyloglucan (PST001) based porous scaffolds (PS) were prepared by crosslinking and freeze drying with a porosity of 90%.

Semi-interpenetrating nanosilver doped polysaccharide hydrogel scaffolds for cutaneous wound healing.

The extensive advancement with novel wound dressing materials functionalized with desirable properties, often touted as a panacea for cuts and burns afflicting various pathologies. However, it would indeed be a hard task to isolate any such material which perfectly fits the needs of any biomedical issue at hand. Biocompatibility, biodegradability as well as non-toxicity of natural polysaccharide served as a versatile and tunable platform for designing natural polysaccharide based scaffolds as an attractive tool in tissue engineering with a greater degree of acceptability.
