Intraoperative variations in intra-axial brain tumor size after craniotomy: a prospective study with histopathological and tumor tissue composition correlation, introducing concepts of tumor expansion and tumor surfacing.

Intraoperative assessment of tumor margins can be challenging; as neoplastic cells may extend beyond the margins seen on preoperative imaging. Real-time intraoperative ultrasonography (IOUS) has emerged as a valuable tool for delineating tumor boundaries during surgery. However, concerns remain regarding its ability to accurately distinguish between tumor margins, peritumoral edema, and normal brain tissue.

Frequency of Central Serous Chorioretinopathy in a Tertiary Care Center in Pakistan.

Background: Central serous chorioretinopathy (CSC) is a significant cause of vision loss in men aged 20 to 60, characterized by serous detachment of the neurosensory retina from the retinal pigment epithelium (RPE). This study aims to assess the frequency of CSC among patients at a tertiary care center in Pakistan, offering insights into its epidemiology and management within this setting.

Methodology: A retrospective observational study was conducted at the ophthalmology department of a tertiary care center from January 2019 to December 2023.

Endothelial Cell Changes After Pars Plana Vitrectomy: A Cross-Sectional Study in a Tertiary Care Center.

Background: A wide variety of vitreoretinal diseases have been majorly treated by the use of pars plana vitrectomy (PPV) as the most commonly practiced treatment option. Despite the fact that it is the most feasible treatment modality, the probability of corneal endothelial cell damage following the treatment remains a matter of great concern. The study aims to inquire about the aftermath of PPV on endothelial cell density (ECD) and spans a time period of six months after the surgery has been performed.

Multi-Agent DRL for Air-to-Ground Communication Planning in UAV-Enabled IoT Networks.

In this paper, we present a novel method to enhance the sum-rate effectiveness in full-duplex unmanned aerial vehicle (UAV)-assisted communication networks. Existing approaches often couple uplink and downlink associations, resulting in suboptimal performance, particularly in dynamic environments where user demands and network conditions are unpredictable. To overcome these limitations, we propose a decoupling of uplink and downlink associations for ground-based users (GBUs), significantly improving network efficiency.

Phytochemical profiling and anticancer potential of extracts against arsenic trioxide induced liver fibrosis in rat model.

Introduction: Arsenic trioxide (AsO) is an environmental contaminant that may cause hepatic injuries. AsO-induced liver injuries are detected as an underlying cause of hepatocellular carcinoma (HCC) around the globe. The present study aimed to investigate the potential of (GL) extracts against oxidative stress and apoptotic activity in HCC-induced rats and to explore molecular docking analysis of phytocompounds of .
