Quinazolinones have various biological activities such as anticancer, antibacterial, antidiabetic, anticonvulsant, antihistaminic, antiinflammatory, antifungal, anthelmintics and antiviral activities. In this research some of compounds 2,3-disubtituted quinazolin-4(3H)-one derivatives had been synthesized under microwave irradiation. The compounds were obtained from reaction some of benzoxazine derivatives with hydrazine hydrate using microwave irradiation and the result of reaction we obtained 82-96%. The products had been tested by IR, 1H-NMR, 13C-NMR and Mass Spectroscopy analysis. The using microwave irradiation was more effective and efficient to produce compounds 2,3-disubtituted quinazolin-4(3H)-one derivative because the reaction runs perfectly without any minor products such as compounds N-(2-(hydrazinecarbonyl)phenyl)benzamide derivatives.

Introduction: The aim of study was to analyze the pattern of malocclusion and their prevalence among patient visiting Dental College, Ranchi to establish baseline date for developing better treatment facility and future research Work. Settings and Design: All the patients were examined in a Dental Chair light and evaluation of Occlusion position in centric occlusion were recorded by asking the subject to swallow and then to Occlude. The samples were divided into Different groups, on the basis of Angle’s classification. A qualitative analysis with Angle’s classification was used to describe the anteroposterior relationship of maxillary and mandibular first molars. Material and Methods: The study was conducted on 1720 patients who attended the orthodontic department from February 2017 to January 2020. Each patient was examined for malocclusion, dentofacial patterns and dentofacial characteristics were recorded. The pattern and prevalence of different malocclusion was assessed. Results: The results of the study showed that most common malocclusion was Angles class I. Total of 1219 (70.66%) Patients reported with Angles Class I malocclusion. The second most common malocclusion was Angles Class II with Increase Over jet 392 (22.72%). The least common malocclusion was Angles Class III 37 (02.14%). Conclusion: Most Prevalent malocclusion among patient consulting for orthodontic treatment in Dental College, Ranchi is Angles Class I malocclusion. Among class I malocclusion crowding of teeth is more prevalent than spacing of teeth.

Background: The uric acid-to-high-density lipoprotein cholesterol ratio (UHR) has emerged as a novel indicator of inflammatory and metabolic status. This study aims to examine the association between UHR and bone mineral density (BMD), as well as the risk of osteoporosis, in individuals aged ≥50 years. Methods: Focusing on participants aged ≥50 years. Femoral neck BMD (FN-BMD) was measured using dual-energy X-ray absorptiometry. Linear regression models were employed to examine the association between UHR and FN-BMD. Additionally, generalised additive models were used to assess the nonlinear relationship between UHR and FN-BMD. Logistic regression models were employed to evaluate the association between UHR and the risk of osteoporosis. Results: adults with a mean age of 64.16 ± 8.92 years. Linear regression analyses revealed a positive association between UHR and FN-BMD, regardless of covariate adjustments. Logistic regression analyses indicated that elevated UHR was associated with a reduced risk of osteoporosis with or without covariate adjustments. Subgroup analyses revealed that the positive association between UHR and BMD was significant in individuals aged ≥65 years but not in those aged 50 to 64 years. Interaction analyses by age showed significant differences after adjusting for all covariates. Conclusions: Clinicians should be vigilant regarding the potential risk of osteoporosis in individuals with a low UHR. UHR might serve as a risk indicator for osteoporosis

Background: Although postoperative shoulder pain surgery is severe, the quality of its management has not been studied in comparison with pain after other orthopedic surgeries. Furthermore, reports have investigated daytime pain, but none have discussed night-time pain. Objective: This study aimed to compare perioperative pain management in patients who underwent Arthroscopic Rotator Cuff Repair (ARCR) and those who underwent lower extremity arthroplasty. Methods: The study population included 33 patients who underwent ARCR and 21 patients who underwent lower- extremity arthroplasty between August 2015 and March 2016. For postoperative analgesia, an interscalene brachial plexus block was used for ARCR, and an epidural block was used for lower extremity arthroplasty. The Visual Analog Scale (VAS) for rest and night pain was measured from the day before the operation to the fourth postoperative day. Results: In ARCR, night pain was significantly weaker on the day of surgery (VAS, ARCR 23.9 vs. lower extremity arthroplasty 47.9; P = 0.008). Conclusion: It was confirmed that postoperative pain can be well managed in patients undergoing ARCR. However, because the pain worsened after the removal of the block, further improvement is required.
