    Get PDF
    Chronic lymphocytic leukemia cancer is a deadly one which affects the bone marrow from making it to produce more amounts of white blood cells in the humans. This disease can be treated either by radiation therapy, bone marrow transplantation, chemotherapy, or immunotherapy. In radiation therapy, the ionizing radiation is used toward the tumor cells, but the main drawback is the radiation may affect the normal cells as well. To overcome this drawback, immunotherapy chimeric antigen receptor (CAR) is used. These CAR cells will target only the antigen of the tumor cells and not damage the normal cells in the body. In this therapy, the T-cells are taken either from the patients or a healthy donor and are engineered to express the CARs which are called as CAR-T-cells. When these CAR-T-cells come in contact with the antigen present on the surface of the tumor cells, they will get activated and become toxic to the tumor cells. This new class of therapy is having a great prospect in cancer immunotherapy

    A REVIEW ON DNA NANOBOTS – A NEW TECHNIQUE FOR CANCER TREATMENT

    Get PDF
    Cancer is one of the deadliest diseases of this century. Tedious and painful radiation therapy and chemotherapy are administered using many drugs including antitumor antibiotics, which cause a lot of side effects. As an alternate, DNA nanorobots serve as a potential cancer treatment technique which is very much safer than other therapies and acts specifically as well. DNA nanobots are said to set a new milestone in the development of medical studies. The primary objective of this bot is to target and eliminate cancer cells from the human body. These bots are made of a single strand of DNA folded into the desired shape. The bots will have two states - an off†position, where the clamshells are closed tightly to bypass healthy cells without any damage and an on†position, where the clamshell opens up to expose cancerous cells to the drug so that the drug can do its job to eliminate the cancer cell. This novel idea will be actively used within the public when it passes its first human trial. In this review, we focus on eliminating cancer cells. Since the bot can be programmed and is capable enough to carry a payload, it can also be used to cure any other diseases as a secondary target. Creation of nanobots has been under progress already and may come within the public after an estimated time of 5 years

    ABSTRACTObjectives: Different parts of jamun tree (Syzygium cumini L. skeels) which belongs to the family - Myrtaceae are well-known for their antidiabeticactivity. Traditional practitioners in India are using the leaf, bark, and fruits of this medicinal plant over many centuries to manage the diabeticpatients. Although several research works have been conducted to prove the efficacy of this plant extracts and also to explore the active principles ofthis plant drug, there is no information regarding the interaction of phytoconstituents of jamun tree with diabetic targets at the molecular level. Hence,this study focused to apply a computational approach to reveal the interaction of molecules of jamun tree with antidiabetic targets.Methods: Lamarckian genetic algorithm methodology was used for docking of 22 phytoconstituents with α-amylase, a key enzyme that involved incarbohydrate metabolism using Autodock software.Results: Analysis of binding energy of ligands with target receptors was remarkably lower especially for friedelin (−9.54 kcal/mol), epifriedelanol(−8.98 kcal/mol), betulinic acid (−8.60 kcal/mol), beta-sitosterol (−8.56 kcal/mol), petunidin-3-gentiobioside (−7.52 kcal/mol), kaempferol (−7.08kcal/mol), petunidin (−6.21 kcal/mol), quercetin (−6.03 kcal/mol), myricetin (−5.80 kcal/mol), and bergenin (−5.27 kcal/mol) when compared tothe synthetic drug acarbose (−2.43 kcal/mol).Conclusion: Potential molecules identified from this study could be considered as a lead to design/synthesize anti-diabetic drug molecules inpharmaceutical industry.Keywords: Jamun tree, Syzygium cumini, Phytochemicals, Diabetes, α-amylase, Molecular docking

    Get PDF
    BACKGROUND & OBJECTIVES : The purpose of this study was to compare the efficacy of platelet rich fibrin assisted with and without laser application in the treatment of periodontal intrabony defects. MATERIALS AND METHODS : Ten healthy patients in age range of 20-60 years, showing bilateral identical intrabony defects were selected. The defects were assigned randomly into Experimental site A (open flap debridement and PRF placement) and Experimental site B (laser disinfection with PRF placement). Clinical parameters such as the plaque index and gingival index were recorded at baseline and at 1 month,3rd month and 6th month post operatively and probing pocket depth and clinical attachment level were recorded at baseline and then 6th month post operatively. The radiographic parameter was recorded at baseline and 6th month post operatively, using standardized intra-oral periapical radiographs taken with long cone paralleling technique and were then assessed using image analysis software. RESULTS : Re-evaluation at 6 months revealed that both the groups showed a significant reduction in probing pocket depth (4.1 ± 0.9mm in experimental site A and 4.7 ± 1.6mm in experimental site B ) and clinical attachment gain (3.7 ± 1.4mm in experimental site A and 4.3 ± 1.8mm in experimental site B). All the clinical parameters were improved slightly better in experimental site B. There was no significant difference between experimental site A and B in bone fill at 6 months post operatively. CONCLUSION : Within the limitations of this study, it can be concluded that, clinically the use of PRF and laser is more effective than PRF alone. But there was no significant difference in bone fill radiographically between two groups

    A REVIEW ON ARTIFICIAL BLOOD: A SOURCE WE NEED

    Get PDF
    Blood is a liquid tissue, in which abundant chemical factors and millions of different cells are dissolved. It is one of the most demanding sources in clinical and medical aspects. The issues and cost of human blood collection and storage directed this procedure toward the use of alternative blood. Thus, came an invention of artificial blood and blood substitutes. These alternative blood or blood substitute is a substance which is made to play as a substitute of erythrocytes. Thus, the main objective is to replace the normal human blood with artificial blood substitutes in the place of blood transfusion during surgeries and organ transfusion. Two major and focused blood substitutes in pharmaceutical aspects are perfluorocarbons and hemoglobin-based oxygen carriers (HBOC's). Among these HBOCs vaguely resemble normal human blood. These blood substitutes are to allow flow through the blood stream to carry the oxygen and supply it to heart and other parts of the blood. They are used to fill the lost fluid volume. They are also called as plastic blood with iron atom as the base. They are found to serve as a good oxygen carrier. The results showed by these products are discussed, and they proved that they can act as a blood substitute and also they can reach the human tissue easier than erythrocytes and can control oxygen directly. However, these artificial blood products are being processed in research laboratories for good outcome. Their important functions are oxygen carrying capacity and to replace the lost blood volume in the human body. Their special features are survivability over a wider range of temperatures, eliminating cross matching, cost efficient, pathogen free, long shelf life, minimal side effects. Thus, artificial blood products are really a good alternative source which we need for replacing normal human blood
