RESUMO

The most common intracanal medication is calcium hydroxide. Its efficacy can be affected by a number of factors, including pH, serum proteins, collagen, and dentin. It's also ineffective against E. faecalis and fungus, lacks an anti-inflammatory component, and has mixed reviews when it comes to pain relief. Natural alternatives to synthetic intracanal medication are being researched at the moment. We evaluated the antioxidant and anti-inflammatory activity of green synthesized silver nanoparticle based intracanal medicaments. Silver nanoparticles integrated into calcium hydroxide and graphene oxide nanoparticles were the experimental groups and Calcium hydroxide served as the control. Antioxidant activity was determined using the DPPH and Nitric oxide assays, while anti-inflammatory activity was determined using the protein denaturation and Xanthine Oxidase Inhibition assays. Both experimental groups had higher antioxidant activity than the control group based on DPPH and Nitric oxide assays. Calcium hydroxide combined with silver nanoparticles demonstrated improved anti-inflammatory efficacy in a protein denaturation and Xanthine oxidase inhibition assay. Within the constraints of an in vitro study, it can be concluded that intracanal medicaments containing silver nanoparticles can be employed efficiently during root canal preparation. In comparison to standard calcium hydroxide-based intracanal medicaments, it has effective antioxidant and anti-inflammatory effects.

RESUMO

Attention deficit hyperactivity disorder (ADHD) is a prevalent psychiatric illness marked by a short span of attention, impulsive decisions, and behavioral issues. They are vulnerable to trauma and dental problems. The dental health team faces a challenge due to behavioral disorders, cognitive deficiencies, and short attention spans. At all stages of prevention and treatment, the management of these children necessitates various changes in approach. To collect data and analyze the awareness level of dental students toward ADHD. An online portal was used for the survey and distributed to 106 dentistry students with self-structured 10 questions. The findings were gathered through the survey portal, and graphs were drawn to compare the results. The SPSS software version 20.0 was used for statistical analysis. The Chi-square test was used to determine the correlation between the variables. Forty percent of those polled are aware of ADHD, which is a mental health condition characterized by excessively active and impulsive behavior. The symptoms of a child with ADHD are aware to 31.43% of voters. About 30.48% of the respondents know the symptoms of an adult with ADHD. About 29.52% of the respondents were aware of the causes of ADHD. To conclude that most dental undergraduates are not aware of the basic characteristics of ADHD. This means that there should be a spreading of knowledge on the subject. A dental student or dentist must know how to manage a patient diagnosed with ADHD. Careful management and treatment will lead to a satisfied and happy patient. Mismanagement may cause problems in the future for both the dentist and the patient.

RESUMO

The present work reported synthesis, characterization, and biocompatibility of starch encapsulated silver nanoparticles (St-PF-AgNPs) and their antibacterial activity. The synthesis of St-PF-AgNPs involved in two steps: (i) synthesis of the biogenic silver nanoparticles using the fungal extracts (PF-AgNPs); and, (ii) encapsulation of starch in PF-AgNPs (St-PF-AgNPs). The surface plasmon resonance was found at 420 nm for the PF-AgNPs while it was at 260 and 420 nm for the St-PF-AgNPs. FTIR spectrum demonstrated the capping and encapsulation of the fungal extracts and starch in PF-AgNPs and St-PF-AgNPs. The XRD and TEM-EDS confirmed the crystalline nature, spherical-shaped , and polydispersed- PF-AgNPs and St-PF-AgNPs with strong signals of Ag. The St-PF-AgNPs showed a Z-average size of 115.2 d.nm and zeta potential of -17.8 (mV) as indicated by DLS and zeta potentials. The cytotoxicity results demonstrated higher toxicity of PF-AgNPs than St-PF-AgNPs in HEK293 cells. The antibacterial activity of St-PF-AgNPs were higher than PF-AgNPs in S. aureus. Overall, this work concluded that the starch encapsulation significantly increased the antibacterial activity of PF-AgNPs and this opens a new avenue for the treatment of bacterial infections through the sustained release of PF-AgNPs to target pathogenic bacterial cells.

RESUMO

Lipocalin 2 (Lcn2, also called as neutrophil gelatinase-associated lipocalin) is a member of the lipocalin family and a known target for breast cancer. Therefore, it is of interest to use Docetaxel as a scaffold to design molecules with improved efficiency from naturally derived phytochemicals. We document 10 analogues (4Deacetyltaxol, 7Acetyltaxol, Cabazitaxel, Cephalomannine, Docetaxal, Deacetyltaxol, Docetaxeltrihydrate, Ortataxel, Paclitaxel, Taxoline) having optimal binding with Lipocalin 2 in comparison with Docetaxel. This data is highly useful for consideration in the design and development of drugs for breast cancer.

RESUMO

Colorectal cancer (CRC) is the most familiar malignancy worldwide. Hence, searching for novel therapeutic options is of highest priority. Therefore, it is of interest to design inhibitors to the protein target importin-11, which transports ß-catenin linked to colon cancer cells. However, the structure of importin-11 is not known. Hence, we use a homology model of importin-11 to dock potential interactions with five phyto compounds using molecular interaction features for further consideration.

RESUMO

Chlamydophila pneumoniae is an intracellular pathogen accountable for various acute respiratory infections. C. pneumoniae has a gene cluster which encodes a putative outer membrane porin (aaxA), arginine decarboxylase (CPn1032 or aaxB) and a putative cytoplasmic membrane transporter (CPn1031 or aaxC). Therefore, it is of interest to document a molecular protein model of porin AaxA from Chlamydia pneumonia to gain structure to functional insight on the protein.
