This review article covers the current research areas in oral pathology and reflects the broad range that encompasses the development and application of software in digital histopathology, implementation of biomarkers in pathology, genetics and epigenetics. Molecular pathology, regenerative medicine and immuno therapy, holds the promising and optimistic future of pathology. Oral and maxillofacial pathology is standing at the forefront of the revolution and new diagnostic tools and knowledge are taking pathologists into broader roles of research and correlating diagnoses for clinicians. While we are still using the same method and material that has been using for the past 100years, it’s time to change. Digital technologies could push the field into becoming more efficient and more scalable. Utilizing  high-throughput, automated digital pathology scanners, it is possible to capture an entire glass slide, under bright field or fluorescent conditions, at a magnification comparable to a microscope. Digital slides can be shared over networks using specialized digital pathology software applications. The future of digital pathology could eventually encompass enhancedtranslational research, computer aided diagnosis (CAD) and personalized medicine.

Eugenol is a phenylpropanoid group compound found in cloves, nutmeg,
cinnamon, and bay leaves. Apart from being used as a cosmetic, perfume, and food
ingredient, eugenol is known to have an antioxidant, antibacterial, anti-inflammatory, and
anti-cancer profile. Eugenol has therapeutic potential by increasing reactive oxygen
species formation, decreasing anti-apoptotic protein Bcl-2, increasing the release of
cytochrome c that leads to apoptosis in cancer cells, and inhibit the epithelial to
mesenchymal transition (EMT) process that could reduce the cell ability to migrating.
We synthesized eugenol loaded chitosan nanoparticles (Nano-EU) by ionic gelation
method to overcome its shortcoming which is volatile and to increase its bioavailability.
The nanoparticles were characterized by using Dynamic Light Scattering (DLS).
Anticancer activity of Nano-EU was investigatedin cervical cancer HeLa cell line by flow
cytometry using Annexin-V/PI staining, and by measuring cleaved-caspase-3 protein
expression which is the executor of the apoptosis process by immunofluorescence.
The results of the study evidenced that Nano-EU inducing apoptosis and increasing
activated caspase-3 expression in HeLa cells. Nano-EU could also inhibit cell migration by
reducing vimentin and Snail as mesenchymal markers leading to inhibition of the EMT
process. Further research is still needed to investigate the anticancer potential of Nano-EU
in HeLa cells to in vivo and clinical studies.

Application of nanoparticles in different industries attracts special attention nowadays. Use of microorganisms is one of the actively studied directions for nanoparticles production. The strain of Pseudomonas stutzeri possessing capacity to bioformation of copper nanoparticles was selected as a result of conducted screening among collection cultures. Earlier this strain revealed activity in terms of biosynthesis of silver nanoparticles too. The possibility to regulate size and form of produced nanoparticles by regulating concentration of ions in the solution was established. The strain is considered as a potential source for development of the technology for production of copper nanoparticles.

Zinc oxide (ZnO) nanoparticles were fabricated by green process in presence of aqueous extract of Watermelon rind. High Performance Liquid Chromatography technique was used to assess the biomolecule content of the aqueous extract prepared from watermelon rind. Citrulline an essential amino acid present in watermelon rind was found to act as capping agent for fabrication of ZnO nanoparticles. The shapes of produced ZnO nanoparticles were found to be anisotropic with few nano rods which were confirmed by TEM analysis. The prepared ZnO nanoparticles were used as antimicrobial agent against pathogens. Higher activity was found against S. paratyphi B strains. Further, the ZnO nanoparticles were assessed for its heavy metal removal capacity from aqueous solution. The results suggest that watermelon rind can be a potential precursor for fabrication of ZnO nanoparticles with versatile applications.

Novel nanoparticles were prepared by using Schiff’s reaction, to produce the nanoparticles Schiff bases (II and III) have been prepared by the composite reaction of graphene oxide and hydrazine hydrate with Isatin and Guanine respectively. On Other hand, Nanoparticle graphene oxide (I) was prepared by using Hummer's method that includes addition of graphite to a mixture of sodium nitrate and concentrated sulfuric acid in the presence of oxidizing agents like potassium permanganate and hydrogen peroxide. The biological activity of the synthesized nanocomposite was studied against various positive and negative gram bacteria by the use of Agar well diffusion method on Mueller - Hinton, the results have shown that the Nano Schiff base II has an interesting inhibition activity especially against the Staphylococcus aureus bacteria. On the other hand, Nano Schiff base III has shown moderate activity against Bacillus thyuringiensis at high concentration of 100μL and it exhibits low - zero inhibition activity against other tested bacteria.

Nanotechnology has laid the foundation to nanomedicine production and still appears the cornerstone for ongoing global medical studies, since at nanometric scale the physical properties of materials vary, resulting in innovative magnetic, biochemical, visual and electrical characteristics. In addition to the huge amount of funds and capital, the emergence of new medicinal products against the changed pathological condition of our bodies is also challenging in view of maximum rate of failure. The modifications with in structures of products in nano particle form, altered the way of diagnosis and treatment of destructive human diseases by using medicines capable in effective management by modifying the step of discharge, delivery and disposal in the body. Smart nanoparticles are such one of the most demanding nano systems for drug delivery to targeted genes that can overcome the problems during treatment itself. Present review paper discussed the types and uses of various types of response-based smart nanoparticles to drug delivery practices.

Bacterial pathogens are major threat to the aquaculture industry and small scale aqua farming. The emergence of various virulence pathogens during the culturing period leads to mass mortality and influence the loss of aquaculture production. As a result it causes economic imbalance. This relies on the very importance position to serve the protein rich sources for human consumption. In order to improve the sustainable aquaculture production the biologically synthesized silver nanoparticles have been used as an alternative method for commercial antibiotics to control such pathogenic infection. Marine microalgae Caulerpa racemosa was used as a silver reducing agent in this study. This controls Pseudomonas aeruginosa infection in tilapia. The bioactive compounds present in the extracts showed potential antioxidant and antibacterial activities against P. aeruginosa infection. The formation of AgNPs was observed by the visualization of the colour change and further confirmed by the UV spectroscopy. It was characterised by Dynamic light scattering measurements (DLS). The antibacterial activity was tested against the fish pathogen. It was found to be effective.

Lycopene has extensively been shown to inhibit tumor growth in nude mice bearing Breast. However, high tumor-suppressive Lycopene dosages encumber the development of oral controlled-release formulations because of a short biological half-life (< 2 h), poor absorption, low aqueous solubility, and extensive first-pass metabolism. Here, we present the design, fabrication, optimization, characterization, and biologicalevaluation of estrone-conjugated lycopene -loaded gelatin nanoparticles for targeting estrogen receptor- positive breast cancer MCF-7 cells. Gelatin nanoparticles (GN) were uniformly compact sized, stable
at physiological pH, and showed good drug entrapment efficiency.
