Urbanization has accelerated globally, with over half of the world’s population now residing in cities. This rapid growth underscores urbanization’s role as a catalyst for economic development and underscores the need for sustainable, accessible neighborhoods. This research aims...

From Market Optimism to Sustainability: How Investor Sentiment Shapes ESG Performance through CEO Power and Board Gender Diversity

ABSTRACT Firms face increasing pressure from investors and stakeholders to enhance environmental, social, and governance (ESG) practices, yet the mechanisms through which market sentiment shapes ESG outcomes remain unclear. This study examines how investor sentiment influences ES...

Proxy-Based Diagnostics of Quantum Oracle Sketching Robustness for Non-IID Sensor and Telemetry Streams

Published quantum-streaming theory establishes quantum memory advantages for specific streaming problems; how a correlation-sensitive proxy model behaves under the structured dependence typical of sensor and telemetry streams, however, remains uncharted. We present a proxy-based...

Clinical performance of a giomer-based pit and fissure sealant with and without air-abrasion pretreatment: a 12-month randomized clinical trial

BACKGROUND: Pit and fissure sealants are widely used for caries prevention; however, their long-term success depends largely on retention. Giomer-based sealants containing surface pre-reacted glass ionomer fillers offer bioactive properties, yet concerns remain regarding their bo...

Early Neuroprotective Effects of Erucic Acid and Gentisic Acid on Hippocampal Glutamate Concentrations and Alzheimer-like Molecular Alterations in an Intracerebroventricular Streptozotocin Rat Model

Background: Alterations in glutamatergic homeostasis have been implicated in Alzheimer’s disease, but the relationship between total hippocampal tissue glutamate and Alzheimer-like molecular alterations remains unclear. This study evaluated the early neuroprotective potential of...

Iliopsoas abscess in crohn’s disease: systematic review of case reports and case series

Transmural inflammation is a hallmark of Crohn’s disease (CD), a chronic inflammatory bowel disease that exposes patients to serious consequences such as fistulas and abscesses. Iliopsoas abscess (IPA) is an uncommon but potentially fatal penetrating (extra-luminal) complication...

Histological evaluation of pulpal healing following direct pulp capping with polytetrafluoroethylene or melatonin, with or without adjunctive low-level laser therapy in Wistar rat molars

Abstract This study evaluated pulpal healing following direct pulp capping with polytetrafluoroethylene (PTFE) or melatonin (MEL), with or without adjunctive low-level laser therapy (LLLT), in Wistar rat molars. Fifty-two maxillary first molars from 26 male Wistar rats were inclu...

Gene flow, kinship, and source population assignment in Chrysomya blow flies

Abstract Blow flies of the genus Chrysomya are among the earliest colonizers of human remains and are important forensic indicators in Africa and the Middle East. However, the population genetic structure of Old World Chrysomya species in North Africa remains poorly understood. W...

Value of computed tomography derived extra cellular volume fraction in prediction of the pathologic grade of rectal adenocarcinoma

Abstract Background Rectal cancer is one of the leading causes of cancer-related deaths worldwide. The degree of tumor differentiation is one of the most important factors on which the prognosis of rectal cancer. The pathological grading of rectal adenocarcinoma is the gold stand...

Sustainable use of phosphogypsum to enhance sandy soils fertility and wheat yield in arid environments

Abstract Purpose Sandy soils in arid regions have low fertility, poor structural stability, and limited water‐holding capacity. This study evaluated phosphogypsum (PG) as a soil amendment for improving sandy‐soil quality and wheat productivity under arid conditions. Methods A fie...

Role of School Nurses in Preventing Digital Addiction and Promoting Health Among School-Age Adolescents

Excessive digital technology use among adolescents has become an increasing public health concern, with growing evidence linking problematic smartphone, internet, gaming, and social media use to sleep disturbances, anxiety, depression, reduced academic performance, cyberbullying...

Experimental Assessment of Postearthquake Reusability and Repairability of Controlled Rocking Masonry Walls with Replaceable Energy Dissipation Devices

Abstract Recent research on controlled rocking masonry walls has focused on self-centering mechanisms with accessible energy dissipation devices and enhanced toe protection strategies to improve seismic performance. Unlike post-tensioned rocking systems, where unbonded post-tensi...

Comparative study of subclinical synovitis and periarticular bone changes in psoriasis patients: impact of biological therapy

Abstract Background Psoriasis (PsO) is increasingly recognized as a systemic inflammatory disease associated with subclinical musculoskeletal involvement that may precede psoriatic arthritis (PsA). This study aimed to evaluate the prevalence of subclinical synovitis and periartic...

Decoding multidimensional water quality in arid industrial lakes: a comprehensive CCME-WQI, HPI, and GIS-based evaluation of the Arab al-Ulayqat system

Effective water quality management is crucial in arid regions, where inland water systems are highly vulnerable to anthropogenic pressure and climatic stress. This study aimed to assess water quality in Egypt’s Arab al-Ulayqat Lakes using physicochemical, microbiological, heavy-m...

Protective effect of Dapagliflozin on hepatic encephalopathy induced by thioacetamide in rats: involvement of ERK, JNK, and Nrf2/HO-1 pathways

Hepatic encephalopathy (HE) is a neuropsychiatric disorder associated with oxidative stress, neuroinflammation, and hyperammonaemia secondary to hepatic dysfunction. This study aimed to investigate dapagliflozin's effects (DAPA) against HE induced by thioacetamide (TAA) in rats a...

Headache across the spectrum of kidney disease: epidemiology, clinical patterns, pathophysiological mechanisms, and management-a narrative review

Abstract Headache is a frequent yet incompletely characterized symptom across kidney-disease populations. Most available literature focuses on chronic kidney disease (CKD), hemodialysis, and kidney transplantation, whereas several clinically important kidney disorders remain poor...

Safety and efficacy of ertugliflozin on heart failure outcomes across cardiovascular diseases: a systematic review and meta-analysis

Sodium-glucose cotransporter-2 inhibitors (SGLT2is) improve cardiovascular outcomes in patients with heart failure (HF) and type 2 diabetes (T2D). However, the efficacy of individual SGLT2is, particularly ertugliflozin, remains less defined. This systematic review and meta-analys...
