Introduction: Phoenix Sylvestris (L.) Roxb also known as date palm or Indian sugar palm, belongs to the Arecaceae family. In our present study, we used the fruit part (epicarp, endocarp). The fruit is very delicious in taste worldwide. It’s flavonoid part is reported with quercetin but its quantification has not yet been reported. Aim: The study aimed to carried out the Quantitative estimation of quercetin from Phoenix sylvestris using a validated HPTLC method. Method: The chromatographic analysis was carried out with the solvent system toluene: ethyl acetate: formic acid (5:4:1, v/v/v) to confirm the presence of quercetin. The HPTLC method was validated by using aluminium-backed silica gel plates with the same solvent system. Quantitative estimation was done by AUC plot. Results: Total Flavonoid Content of the methanolic extract of Phoenix sylvestris is 0.79 mg QE/g. The HPTLC method was good, accurate and specific. The methanolic extract was found to possess 1.07mg/100g of quercetin. Conclusion: This study discussed the validated HPTLC method which is simple, accurate and sensitive tool for...

Introduction: The goal of BTS (Blood Transfusion Service) is to provide safe and quality blood and blood products to needy patients. In developing and underdeveloped countries, there exists a gap between the demands and supply of blood products. Since 100% voluntary blood donation is not achieved, we rely on replacement donors also. Hence this study was attempted to assess the seroprevalence of TTI (transfusion-transmitted infection) in blood donors and to compare the seroreactivity rate between voluntary and replacement donors. Materials and Methods: This retrospective study was done on the blood donors over the period of 4 years from January 2020 to December 2023 in a tertiary care hospital. Donor samples were screened for the five mandatory TTIs, viz., HIV (human immunodeficiency virus), HBV (hepatitis B virus), HCV (hepatitis C virus), syphilis, and malaria. Results: A declining trend in HBV was evident from 2020 to 2023. Prevalence of syphilis was highest in 2022. No marked change noted with HIV and HCV. The TTI rate in non-remunerated voluntary blood donors (NRVBD)...

This study investigates the diagnostic utility of Diffusion Weighted Imaging (DWI) and Apparent Diffusion Coefficient (ADC) values in evaluating intracranial lesions. A cross-sectional analysis of 44 patients was conducted, examining age and gender distribution, histopathological types, and grades of brain tumors. The highest proportion of individuals (22.7%) was within the 0-10 age range, with males comprising 56.8% of the sample. The study focused on supratentorial and infratentorial lesions, categorized by WHO grades, highlighting that Grade IV lesions were most common in both regions. High-grade tumors (WHO Grade III and IV) demonstrated lower ADC values, indicating restricted diffusion, while non-neoplastic conditions such as arachnoid and epidermoid cysts exhibited higher ADC values, reflecting increased diffusion. The presence of perilesional edema was more frequent in higher-grade tumors, underscoring their aggressive behavior and impact on surrounding brain tissue. Diffusion restrictions were significant in Grade IV lesions, with both partial and complete restrictions observed. The Receiver Operating Characteristic (ROC) curve analysis revealed an Area under the Curve (AUC) of 0.70, indicating that DWI possesses...

Objectives: The anti-inflammatory activity of powdered almond gum (Prunus dulcis) was studied by using HRBC membrane stabilizing method and the bioactive compounds which are responsible for anti-inflammatory activity was analyzed by using FTIR analysis. Methods: To study the in-vitro anti-inflammatory activity Human red blood cell (HRBC) membrane stabilization method has been used and for identification of functional groups Fourier Transform infra-red spectroscopy was used. Result and Conclusion: Almond gum resin serves as a good anti-inflammatory agent due to the presence of saponins, steroids, terpenoids and xylan which were identified from FTIR...

Urinary bladder lesions are responsible for significant morbidity and mortality throughout the world. Majority of the bladder tumors are epithelial in origin with most of them accounting for urothelial/ transitional neoplasm. The present study was conducted to assess various types of urinary bladder lesions with regard to frequency, age and sex distribution and to describe the histopathological features of various lesions in the urinary biopsies along with grading of urothelial neoplasm. The present Hospital based cross sectional study was conducted in Assam Medical College and Hospital, Dibrugarh for a duration of 1 year (1st June 2017- 31st May 2018). Out of the 35 cases, the male: female ratio was 4:1, the Mean ± S.D of age of presentation was 60.31 ± 13.42 years. Out of 33 urothelial neoplasms, 14 (42.42%) cases were graded as high grade, 17 (51.52%) cases as low grade and one each of inverted papilloma and papillary urothelial neoplasm of low malignant potential. The early and definitive histopathological diagnosis with accurate grading and staging can aid...
