1. Andrographolide A Potential Therapeutic Drug Against Breast Cancer: A Review
Sheethal S. Kumar, John E. Thoppil
Breast cancer is the leading cause of cancer death among females. It occurs due to the uncontrolled proliferation of breast epithelial cells. Plant-derived drugs are more efficacious than synthetic drugs since it lacks side effects. Andrographolide is an active principle of the herb Andrographis paniculata
) Nees. It is a potent therapeutic drug against breast carcinoma. It induces breast cancer cell‐cycle arrest at G0/G1 phase via the induction of cell‐cycle inhibitory protein p27 and decreases the expression of cyclin‐dependent kinase 4 (CDK4). It also activates the intrinsic apoptotic pathway, via the induction of bax and bak. It enhances caspase production and p53 gene expression. Andrographolide inhibits angiogenesis and metastasis of breast carcinoma. Andrographolide nanoparticle production and synergetic therapies of andrographolide along with other chemotherapeutic drugs is a breakthrough in breast cancer treatment.

The objective of this study was to investigate the potential of emulgel as a topical delivery system to enhance the permeation of Boswellia serrata
(BS). BS loaded emulgel was prepared using 32
factorial design and were characterized using Scanning electron microscopy, % drug content and spreadability determination. The design of experiment was done to optimize the result, and then surface plots were generated to compare with the practical results. The prepared BS loaded emulgel showed an average spreadability of 29.840–75.6 g.cm/s, pH of all formulation was in range of 6.3 to 7.09. Rheological behaviour was studied using viscosity measurements and skin irritation test was performed to evaluate biocompatibility of formulation. Skin permeation study was carried out with rat dorsal skin using modified Franz diffusion cell. BS emulgel showed high drug deposition on excised rat skin, test showed biocompatibility of formulated emulgel. These results show that BS loaded emulgel as superior topical application vehicle for Boswellia serrata.

Lekhana.S, Kanishka. B, Sneha Thakur
Nanotechnology is the field of science that encompasses the production of nanoparticles at nanoatomic scale. The nanoparticles size governs wide range of therapeutic properties. The nanostructures when formulated using DNA or RNA materials can result in enhanced hydrophobic properties, shelf life and also may enhance targeted drug delivery. Structured or dynamic DNA nanostructures involve basic nucleotide pairing with protein backbone. The DNA nanostructures produced by Bottom to Top approach are currently being applied in medicine, cancer, ophthalmic drug delivery and also for diagnosis and treatment. They involve complimentary DNA base pairing (AT/GC) for strong interaction resulting in formulation of structures with 10-50mm size. RNA nanostructures are multifunctional manipulative structures synthesized using Bottom-Up approach which results in modulated physiochemical properties and enhanced stability. RNA nanoparticles are currently exploited in the field of cancer. Both DNA and RNA nanostructures are 2D/3D multi dimensional models which are novel structures in the field of nanoscience. DNA/RNA nanostructures can be identified by Killer Killiani test , Quantitative estimation and also spectroscopic methods like UV, SDS-Page, XRD, SEM and DLS techniques can be applied. The wide range of applications of these DNA/RNA nanostructures are currently considered as an area of interest in field of therapeutics by most of the researchers. The current review describes the core nature of Nucleic acid nanostructure-DNA/RNA build nanoparticles, characterization techniques, Design, optimization, analysis of nucleic acid nanostructures and their diverse applications.

7. Physical Characterization and In-Vitro
Sun Protection Factor Determination of Anti-Ageing Poly Herbal Cream
Usha Kiranmai G, Shayeda
Ageing may be due to simple chronological passing of years or may be due to photageing induced by prolonged exposure to the sun. Herbal cosmetics are the preparations used to enhance the human appearance by playing a major role in impeding and reversing ageing of the skin. Thus, Herbal creams are safe to use and can be used as the provision of a barrier to protect skin. In the present study, four creams (AA1, AA2, AA3 & AA4) were formulated by varying the concentrations of herbal oils like tamanu oil, lavendor oil etc, for physical characterization and also to determine the in-vitro
sun protection factor of anti-ageing poly herbal cream. The evaluations were done for all the formulations on the parameters like pH, spreadability, extrudability, stability etc. The UV-B protection of a sun care product is given by the Sun Protection Factor (SPF). In-vitro
sun protection factor (SPF) was determined using Mansur equation by UV-Spectrophotometer at the range of 200-320 nm. All formulations showed good spreadability, good consistency, homogeneity with good appearance, pH, no evidence of phase separation and ease of removal. But a little change in color was observed for creams AA2 & AA4. The formulations AA1 and AA3 showed no redness, edema, inflammation and irritation to the skin during irritancy studies on rabbits. In-vitro
SPF of AA1 & AA3 were found to be 2.16 ± 0.57 and 2.21 ± 0.60 respectively. Stability studies were also performed over a period of 3 months while maintaining the products at 4 °c, 25 °c and 40 °c as per ICH guidelines for the parameters like pH, spreadability, extrudability and viscosity. Statistical analysis was also performed using SPSS software 17.0 version. Ultimately, AA1 and AA3 were found no change and maintained their stability during the period of three months and by statistical analysis.
