Biochemical Approach

Ayurvedic medicine is a system of traditional medicine native to India. Ayurveda is based on peculiar fundamental principles like Shatpadarth, Tridosha Theory, Panchamahabhuta Theory, Prakriti, Ojas, Dhatu, Mala, Agni, Manas, and Atma etc. The concepts of Ayurveda are expressed with Gunas. The increased elements are treated by opposite Guna. In support of the above concept, an experimental study on the 3T3-L1 cell line is carried out for examine the adipocytic and anti adipocytic activity of Snigdha and Ruksha Guna respectively. The results were assessed with the help of evaluation of sublethal concentration by using XTT assay and lipid assay. The aim of basic research in Ayurveda through bioscience is to explore scientific innovation and opportunities in fundamental concept of Ayurveda. Fundamental research needs to be done to highlight the concept of gurvadi guna through the in vitro study.

Universal Adhesives

Dental universal adhesives are considered an useful tool in modern dentistry as they can be used in different etching techniques, allow for simplified protocol and provide sufficient bond strength. However, there is still no consensus as to their toxicity towards pulp. Thus, the present study aimed to evaluate the cytotoxicity and genotoxicity of three universal adhesives: OptiBond Universal, Prime&Bond Universal and Adhese in an in vitro experimental model, monocyte/macrophage cell line SC (ATCC CRL-9855). The cytotoxicity was measured by means of XTT assay, whereas the genotoxicity (comet assay) was evaluated based on the percentage of DNA present in the comet tail. Furthermore, the ability of the adhesives to induce apoptosis was analyzed using flow cytometry (FC) with the FITC annexin V/propidium iodide (PI) double staining. The analysis of the cell cycle progression was performed with FC using PI staining. OptiBond Universal presented significant, while Prime&Bond Universal and Adhese Universal had minimal cytotoxicity and genotoxicity towards human SC cells. Moreover, only OptiBond Universal increased the level of apoptosis in SC cell line. None of the adhesives showed significant cell cycle arrest, as revealed by FC analysis. Due to substantial differences in toxicity in in vitro studies of dental adhesives, there is a great need for further research in order to establish more reliable test protocols allowing for standardized methodology.

Significant Impairment

Background: In the latest years, there has been an increased interest in nanomaterials that may provide promising novel approaches to disease diagnostics and therapeutics. Our previous results demonstrated that Carbon-dots prepared from N-hydroxyphthalimide (CD-NHF) exhibited anti-tumoral activity on several cancer cell lines such as MDA-MB-231, A375, A549, and RPMI8226, while U87 glioma tumor cells were unaffected. Gliomas represent one of the most common types of human primary brain tumors and are responsible for the majority of deaths. In the present in vitro study, we expand our previous investigation on CD-NHF in the U87 cell line by adding different drug combinations. Methods: Cell viability, migration, invasion, and immunofluorescent staining of key molecular pathways have been assessed after various treatments with CD-NHF and/or K252A and AKTVIII inhibitors in the U87 cell line. Results: Association of an inhibitor strongly potentiates the anti-tumoral properties of CD-NHF identified by significant impairment of migration, invasion, and expression levels of phosphorylated Akt, p70S6Kinase, or by decreasing expression levels of Bcl-2, IL-6, STAT3, and Slug. Conclusions: Using simultaneously reduced doses of both CD-NHF and an inhibitor in order to reduce side effects, the viability and invasiveness of U87 glioma cells were significantly impaired.

Breast cancer is the subsequent foremost reason of cancer death in a woman and ranks as the primary foremost reason of death in India. In its conduct, several measures and recommendation are considered. Homoeopathic medicines are one of the part of a corresponding, and another medicine is utilized for the treatment of cancer. The main purpose of the investigation is to evaluate the anticancer action of homoeopathic arrangements of Asterias rubens  on the basis of the similia principle. We directed an in vitro study using MTT assay to control the result of ultra diluted homoeopathic preparation in contradiction of two human breast glandular cancer cell lines(MCF-7 and MDA-MD- 231), frequently used for the breast cancer treatment, by testing the feasibility of breast cancer (MCF-7 and MDA-MD-231) cell line, with various attenuations of Asterias rubens  at 24 hrs. Multiple comparisons between tested reagents at different concentrations confirmed the significance of the said results. At a dilution of 1:25 6CH and 30CH potency shown superior activity on MCF-7 and no such significant changes on MDA-MD-231 at any dilutions As it fails to offer estrogen receptor(ER) Also progesterone receptor (PR) expression, and also HER2 (human epidermal development variable receptor2) so continuously a triple-negative breast cancer it will be a hostility manifestation for breast cancer with restricted medicine choices. However, further potency needs to be tested. These preliminary significant results warrant further in vitro and in vivo studies to estimate the possible of Asterias rubens  a medicine to treat breast cancer.

Abstract Approximately 60–70% of EWSR1-negative small blue round cell sarcomas harbour a rearrangement of CIC, most commonly CIC-DUX4. CIC-DUX4 sarcoma (CDS) is an aggressive and often fatal high-grade sarcoma appearing predominantly in children and young adults. Although cell lines and their xenograft models are essential tools for basic research and development of antitumour drugs, few cell lines currently exist for CDS. We successfully established a novel human CDS cell line designated Kitra-SRS and developed orthotopic tumour xenografts in nude mice. The CIC-DUX4 fusion gene in Kitra-SRS cells was generated by t(12;19) complex chromosomal rearrangements with an insertion of a chromosome segment including a DUX4 pseudogene component. Kitra-SRS xenografts were histologically similar to the original tumour and exhibited metastatic potential to the lungs. Kitra-SRS cells displayed autocrine activation of the insulin-like growth factor 1 (IGF-1)/IGF-1 receptor (IGF-1R) pathway. Accordingly, treatment with the IGF-1R inhibitor, linsitinib, attenuated Kitra-SRS cell growth and IGF-1-induced activation of IGF-1R/AKT signalling both in vitro and in vivo. Furthermore, upon screening 1134 FDA-approved drugs, the responses of Kitra-SRS cells to anticancer drugs appeared to reflect those of the primary tumour. Our model will be a useful modality for investigating the molecular pathology and therapy of CDS.
