Abstract
Human bone marrow stromal cell (hBMSC)-derived exosomes are promising therapeutics for inflammatory diseases due to their unique microRNA (miRNA) and protein cargos. Periodontal diseases often present with chronicity and corresponding exuberant inflammation, which leads to loss of tooth support. In this study, we explored whether hBMSC exosomes can affect periodontitis progression. hBMSC exosomes were isolated from cell culture medium through sequential ultracentrifugation. miRNAs and proteins that were enriched in hBMSC exosomes were characterized by RNA sequencing and protein array, respectively. hBMSC exosomes significantly suppressed periodontal keystone pathogen Porphyromonas gingivalis-triggered inflammatory response in macrophages in vitro. Transcriptomic analysis suggested that exosomes exerted their effects through regulating cell metabolism, differentiation, and inflammation resolution. In vivo, weekly exosome injection into the gingival tissues reduced the tissue destruction and immune cell infiltration in rat ligature-induced periodontitis model. Collectively, these findings suggest that hBMSC-derived exosomes can potentially be used as a host modulation agent in the management of periodontitis.

Abstract
Oral route is one of the most accepted and convenient mode of drug administration, however low oral bioavailability of many drugs is a major concern which limits their oral administration. Optimum solubility and permeation of a drug across the intestinal epithelium is a prerequisite to reach the systematic circulation in the active form for effective action at the desired site. Physicochemical properties of the drug, physiological factors and pharmacokinetic factors are mainly responsible for their low solubility, low permeability and high metabolism which in turn into low oral bioavailability of the drug molecules. In this review, various factors which affect bioavailability of drugs and possible approaches to overcome this problem have been discussed. The review identifies various areas for research that can be focused for improving oral bioavailability of therapeutic molecules for different classes of drugs, thus making the oral route of administration of the drugs more effective and useful.

Abstract
A simple, rapid, precise and accurate isocratic reversed-phase high performance liquid chromatography (HPLC) method was developed and validated for the simultaneous determination of paclitaxel and ellagic acid in a combination nanoformulation. Separation was achieved using a 25 x 4.6 mm column, particle size 5 microm C18 reverse phase column (Luna), with a mobile phase consisting of methanol and 0.05% H3PO4, in gradient elution mode with a mobile phase flow rate of 1 mL/min, using UV visible detection at 230 nm. Sharp and well defined peaks were obtained at retention times of 13.75 min. and 11.6 min. for paclitaxel and ellagic acid, respectively. Regression analysis showed a good linear relationship (r2 = 0.996 +/- 0.0011) and (r2 = 0.993 +/- 0.0011) over wide ranges of 5-500 microg/ml and 1-500 microg/ml for paclitaxel and ellagic acid, respectively. LOD and LOQ of paclitaxel were 30 ng/ml and 100 ng/ml, respectively, while for ellagic acid LOD and LOQ were 300 ng/ml and 1 microg/ml, respectively. The accuracy of the method was determined by recovery studies using the standard addition method and was found to be in the range of 99.61-101.21% and 98.70-102.22% for paclitaxel and ellagic acid, respectively. The relative standard deviation (% RSD) for precision, repeatability and robustness was less than 2%. The ellagic acid content in fruits of Punica granatum and combination formulation with paclitaxel was analyzed and found to be 0.04% w/w and 0.0012%w/w, respectively. The proposed, developed and validated HPLC method for the simultaneous quantification of ellagic acid and paclitaxel can be used for the quality control and standardization of several crude drugs and different combination formulations, in which ellagic acid is present.

Abstract
This study was aimed to develop chitosan coupled lipid nanoparticle (Ch-Ptx-Lip), where immunomodulatory activity of chitosan and chemotherapeutic effect of paclitaxel can synergistically enhance efficacy of this novel drug delivery system. Particle size, zeta potential and % Entrapment Efficiency (%EE) of Ch-Ptx-Lip was found to be 113.3 +/- 4.5 nm (PDI: 0.38), (+)35.7 +/- 2.9 mV and 96.4 +/- 1.8% respectively. Morphological evaluation of these particles by TEM shows circular bilayer structure along with outer polymer layers. Ch-Ptx-Lip showed significantly enhanced cytotoxicity (p < 0.05) compared with marketed formulation (Ptx Solution) and Ptx-Lip when evaluated in-vitro by MTT assay on MCF-7 cell lines. Improved efficacy with lower dose of drug can be a new strategy against cancer with minimum side effects and shorter treatment duration.

Abstract
The present study explored the transdermal permeation enhancing mechanism of non-ionic surfactant vesicles (proniosomes) of frusemide across rat skin. Fourier Transform Infrared Spectroscopy (FT-IR), Differential Scanning Calorimetry (DSC), activation energy and histological examination were carried out to study the mode of action of the optimized proniosome formulations PGS [Span 40:soyalecithin:cholesterol (4.5:4.5:1)] and PGD [Span 40:dicetylphosphate:cholesterol (4.5:4.5:1)]. The IR spectra showed a prominent decrease in peak areas and heights of CH2 stretchings but did not show shift of these peaks and shift in amide bands. DSC studies also confirmed the IR findings. It was concluded that the proniosomes disrupted the lipid bilayer by extracting the lipids thereby creating pathways for drug penetration. The significant decrease in activation energy for frusemide permeation across rat skin indicated the SC lipid bilayers were significantly disrupted (p<0.05). Histological investigations were carried out. Disruption and extraction of lipid bilayers as distinct voids and empty spaces were visible in the epidermal region. Overall, our findings suggested that proniosomal formulations offer a promising means for non-invasive delivery of frusemide, especially due to their ability to modulate drug transfer and serve as non-toxic permeation enhancers.

Abstract
Sphere-in-oil-in-water (s/o/w) multiple emulsions containing diclofenac sodium were prepared by gelatinization of inner aqueous phase. A further modified version (s/o/wp) of s/o/w was formulated by adding 5.0% w/v poloxamer 403 to the external aqueous phase during the second step of emulsification in order to affect the adsorptive coating on the surface (s/o/wp). The inverse targeting of reticuloendothelial system (RES) rich organs was compared with a non reticuloendothelial system after intravenous administration of s/o/w multiple emulsion (treatment I) and poloxamer containing s/o/wp multiple emulsion (treatment II). The amount of diclofenac sodium in the plasma and various organs was measured to elucidate the effect of inverse targeting to RES and targeting to other tissues in terms of the incorporated drug. After i.v. administration, the half life (34.65 vs.16.26 h) and apparent volume of distribution of diclofenac sodium (2815 vs. 1671.5 ml/kg) were significantly higher in treatment II than in treatment I. It is concluded that the amount of drug in RES rich organs (spleen, liver) were significantly lower than the values in non-RES organs such as lungs, inflammatory tissue (synovial fluid) in treatment II than in treatment I.
