Implications of Pyrolytic Gas Dynamic Evolution on Dissolved Black Carbon Formed During Production of Biochar from Nitrogen-Rich Feedstock.

Gases and dissolved black carbon (DBC) formed during pyrolysis of nitrogen-rich feedstock would affect atmospheric and aquatic environments. Yet, the mechanisms driving biomass gas evolution and DBC formation are poorly understood. Using thermogravimetric-Fourier transform infrared spectrometry and two-dimensional correlation spectroscopy, we correlated the temperature-dependent primary noncondensable gas release sequence (HO → CO → HCN, NH → CH → CO) with specific defunctionalization stages in the order: dehydration, decarboxylation, denitrogenation, demethylation, and decarbonylation.

Evaluation of Anti-Obesity Potential of Isolated Bioactive Fractions from Justicia Adhatoda Leaves: An In Vitro, In Vivo, and 3T3-L1 cell line Approach Using HPTLC-MS-MSn for Compound Identification.

This study was conducted to investigate the anti-obesity effects of bioactive fractions JAF2 and JAF3 from Justicia adhatoda (JA) in vitro using enzymatic assays, 3T3-L1 cells and in vivo using a monosodium glutamate-high-fat diet (MSG-HFD) model. High-Performance Thin Layer Chromatography coupled with Mass Spectrometry (HPTLC-MS-MSn) was finally utilized to analyze bioactive fractions for the compounds responsible for the activity. In vitro, the anti-obesity effects of JAF2 and JAF3 were assessed in 3T3-L1 adipocytes, revealing that JAF2 significantly reduced lipid and triglyceride levels.

Primary intrarenal hemangioma - A series of 39 cases.

Intrarenal hemangiomas lack concise clinicopathologic information, due to the predominance of single case reports and inclusion of other vascular neoplasms and hemangiomas of perirenal, hilar, and renal vein origin. Herein, in this multi-institutional study we evaluate clinicopathologic features of 39 intrarenal hemangiomas. The median age was 62 years (range = 27-94 years; 2:1 male to female ratio), with left-sided predominance (left = 21, right = 13; one case was bilateral).

Assessment of Knowledge, Awareness, and Practices of Human Papillomavirus Infection and Vaccination Among Medical and Dental Students: A Cross-Sectional Study.

Introduction Human papillomavirus (HPV) is the most common causative agent for cervical cancer (CC) in women. Despite extensive initiatives, the acceptance and implementation of vaccinations have remained inadequate, hindering a significant impact on public health outcomes. This study aimed to provide a comprehensive assessment of the knowledge, awareness, and practices (KAP) scores of medical and dental students regarding HPV infection and vaccination.

Development and Validation of a Routine Electronic Health Record-Based Delirium Prediction Model for Surgical Patients Without Dementia: Retrospective Case-Control Study.

Background: Postoperative delirium (POD) is a common complication after major surgery and is associated with poor outcomes in older adults. Early identification of patients at high risk of POD can enable targeted prevention efforts. However, existing POD prediction models require inpatient data collected during the hospital stay, which delays predictions and limits scalability.
