02). In the PS group, the colony count did not follow a certain pattern over time, neither in the 10 Ncm nor in the 20 Ncm torque. The mean colony count in the PS group was lower than that in the PM group at all time points in both torques. This difference was not significant at day 1, irrespective of torque value, but it was significant at 7 and 14 days, in both 10 and 20 Ncm torques (P less then 0.05). Thus microleakage is lower in PS than PM design. The selection of a PM or PS design is a more important factor than the applied torque (10 or 20 Ncm) for reduction of bacterial microleakage in Tube-in-Tube implant systems with screw-retained connections.Purpose - Dental implants in the anterior mandible have become increasingly common due to popular prosthetic treatments. The aim of this study was to evaluate cone beam computed tomography (CBCT) images of mandibles from edentulous patients in need of anterior dental implants to present qualitative descriptions in the mental interforaminal region and to present a new classification. Material and Methods - A total of 180 (CBCT) scans of patients requiring implant installation in the anterior mandible for implant assisted overdenture treatment plan were evaluated regarding parameters such as ridge height, width, inclination, and undercuts. All assessments were performed on the cross-sectional images mesial to the mental foramen. Results - The most common ridge morphology was cylindrical (74.1%) followed by atrophic (19.4%) and undercut (6.4%). The prevalence of atrophic ridge was significantly higher in females and ridge with undercut was significantly more detected in males (P less then 0.05). selleck chemicals llc D1 and D2 bone types was detected higher in males than in females (P less then 0.05). Conclusion - Cylindrical morphology was the most prevalent features of anterior mandible of edentulous patients. A CBCT scan is a useful diagnostic tool providing important information about anatomical structures and morphological variations in the sites of interest.Success of dental implants depends on the quality and quantity of local bone, implant designs, and surgical technique. The amount and density of available bone in the patient's edentulous site are primary determining factors in predicting individual patient success. Our present study aims to analyze the mean bone availability to the choice of implant width and length and bone width and length compared with the adjacent teeth and condensing osteitis. This descriptive study was done at the Saveetha Dental College and Hospitals, Chennai. Retrospective data of bone width, bone height, implant width, implant height, adjacent teeth presence, and condensing osteitis presence were evaluated from the digital data to assess operators' implant dimensional choice. Residual bone height availability is in the range of 0-2 mm (about 52.1%). Residual bone width availability is in the range of 0-2 mm (about 56.9%). Presence of adjacent teeth is 79.8% and presence of condensing osteitis is 12%; these results were subjected to chi-square test. Presence of adjacent teeth tends to dictate the choice of width of implant whereas the length of implant is not much changed from planned length and width.Introduction - Scaffolds and cells are two important components in bone tissue engineering. There is a gap of information about stem cell activity next to bone substitutes. Thus, the aim of this in vitro study was to compare the proliferation and differentiation of bone marrow stem cells (BMSCs) and dental pulp stem cells (DPSCs) in presence of freeze-dried bone allograft (FDBA). Method and Materials - DPSCs and BMSCs were cultured and placed on mineralized bone allograft. Cell proliferation was analyzed by the methyl thiazolyl tetrazolium (MTT) assay after 24, 48, and 72 h. To compare the enzymatic activity and mineralization of cells, the alkaline phosphate (ALP) test and alizarin red staining were performed at 30 days. Data were analyzed by ANOVA. Results - The rate of proliferation of DPSCs was higher at 48 and 72 h. ALP activity was significantly higher in DPSCSs (P less then 0.05), while alizarin red staining did not show any significant difference between the groups in formation of calcified nodules. DPSCs showed higher cell proliferation and osteoblastic differentiation than BMSCs. Conclusion - Considering the easier and less invasive isolation of DPSCs, a combination of DPSCs and allograft can be a good choice for bone regeneration, especially in the dentoalveolar area.Several impression techniques have been proposed to achieve passive fitness between the prosthesis and the osseointegrated implant. The aim of this study was to compare closed tray implant impression techniques using snap-on and impression analogues on a clinical radiographic scale. The current study was comparative, descriptive, and retrospective, performed in a university setting in 2020. The data of patients reporting to the Department of Implantology between June 2019 to March 2020 were collected from patient records, and the data of 1000 plus patients were analyzed for snap-on impressions and impression analogue accuracy in seating and associated jig trial seating. A comparison of closed tray implant impression techniques using snap-on and impression analogues on a clinical radiographic scale found both to be perfect. The impression recorded with snappy with abutment and the impression recorded using impression coping exhibited no differences during jig trial seating verification. This study showed that both impression procedures are accurate and can be used for implant impressions.Chimeric antigen receptor (CAR) T cell therapy consists of the gene transfer of a cassette encoding a receptor capable of redirecting the transduced T cell toward a specific cytotoxic response against tumor cells. The therapy has been providing a new perspective on some hematologic malignancies, such as CD19+ lymphomas and acute lympho-blastic leukemia. CAR-T cell-based therapies are now approved for commercial distribution in different countries. Over the years, several modifications were necessary in the CAR structure to get it to its current results. CAR-T strategies still have plenty of room for improvement in order to improve clinical benefits and to overcome some of the limitations that still impair broader application. One main issue is the dysfunctional acquired phenotype, provoked by tumor inhibitory molecules or even exacerbated signaling by the CAR molecule itself. In this regard, Many research groups focus on discrete incremental modifications in each of the CAR molecule domains of the conventional structure looking for better response. Among these redesign strategies are the modulation of the binding affinity, use of costimulatory molecule ligands, and control of intracellular signaling. This review focuses on the newest reports covering structure changes in the CAR molecule capable of eliciting improved responses by transduced cells.Immunotherapy has emerged as a potent and effective treatment for multiple cancer types. For example, the engineering of T cells through the expression of chimeric antigen receptor (CAR) against tumors has shown remarkable potential. This review outlines clinical applications of CAR-T cell therapy in hematological malignancies and solid tumors, with a focus on the main challenges related to the safety and efficacy of the current CAR-T cell therapy and the promising strategies to maximize antitumor efficacy while minimizing adverse events. Finally, we present the future outlook of CAR-T cell therapy for the treatment against malignancies. We believe that potential problems can be overcome by strategies to further facilitate effective clinical translation and improve the efficacy, especially through the combination of different approaches.Chimeric antigen receptor T (CAR-T) cells are proving their value in hematological cancers such as B cell acute lymphoid leukemia (B-ALL). This success is in great part due to the chosen target antigen, the lineage marker CD19, that is expressed by leukemia blasts and B lymphocytes, which are not crucial. For solid tumors, the challenge is greater because antigen expression is highly heterogeneous within the tumor and even an efficient CAR-T strategy would not kill all tumor cells. Also, many antigens are shared between solid tumors and healthy cells, causing off-target cell lysis and dangerous collateral damage. New antigen sources are emerging as targets, such as viruses, endogenous viruses, and immune checkpoint molecules. New technologies are in search of the ideal target, with antigen combinations the leading candidates.The field of cell therapy is leading a paradigm shift in drug development. The recent convergence of several fields, including immunology, genetics, and synthetic biology, now allows for the introduction of artificial receptors and the design of entire genetic circuitries to finely program the behavior of injected cells. A prime example of these next-generation living drugs comes in the form of T cells expressing chimeric antigen receptors (CARs), which have already demonstrated definitive evidence of therapeutic efficacy against some hematological malignancies. However, several obstacles still restrict the antitumor efficacy of and impair the widespread use of CAR-T cells. Critical challenges include limited persistence and antitumor activity in vivo, antigen escape, scarcity of suitable single markers for targeting, and therapy-related toxicity. Nevertheless, intense research activity in this field has resulted in a plethora of creative solutions to address each of these limitations. In this review, we provide a comprehensive snapshot of the current strategies used to enhance the therapeutic efficacy, applicability, and safety of genetically engineered immune cells to treat cancer.Genetically engineered T-cell therapies have the adeptness to modernize and revolutionize the treatment of cancer. Cancer immunotherapy, by depending on this fundamental recognition method, supports the antitumor viability of T cells and extends adaptive immunity by encouraging adoptive transfer of genetically engineered T cells. T cells assume a key part in cell-mediated immunity as well as to make strategies for genetically modify T cells, counting chimeric antigen receptor (CAR) T-cell therapy and T-cell receptor (TCR) T-cell therapy. They have accomplished significant advances in the treatment of neoplastic diseases. Tumor cells can produce neoantigens that can possibly be immunogenic, as mutated proteins or proteins with reformed translational processing can be viewed as unfamiliar or foreign by immune system. Recognizable human tumor antigens have prompted a superior understanding the idea of tumor antigens, anti-tumor immune reactions in immunotherapeutic patients as well as tumor escape mechanisms. Furthermore, paucity of exceptionally and homogeneously expressed tumor antigens and intrinsic plasticity of neoplastic cells provide key challenges to specificity, effectiveness, and generally adequacy of genetically engineered T-cell therapies. Difficulties ranges from the determination of antigen targets and managing regulatory and safety issues to effectively explore routes to commercial advancement. In any case, the empowering clinical information, advancement in scientific understanding of tumor immunology along with improvements in manufacture of cell products are altogether propelling the clinical interpretation of modern cancer immunotherapies. In this review, we sum up the advancement of genetically engineered T cells, tumor antigen with intrigue the most recent investigation regarding genetically engineered T cells for cancer immunotherapy, and to confer strategies for refining enactment of these T cells to combat cancers.
