Although Leucaena leucocephala has long been used for its hepatoprotective, anticonvulsant, antioxidant, and anticancer properties, there has been no rigorous pharmacological validation. The anticonvulsant, antioxidant, and in vitro cytotoxic activities of L. leucocephala leaf methanol extract were investigated as the aim of the study. The presence of flavonoids, tannins, phenols, saponins, alkaloids, and terpenoids was verified by phytochemical screening. DPPH, ABTS, and FRAP tests were…

The present study aimed to explore anti-arthritic potential of the plant Merremia dissecta, a perennial weed and also a shrub like plant which is commonly used as a medicine in folk treatment by In-vitro protein denaturation method. The leaves of the plant were harvested, dried and extracted in methanol. Anti-arthritic activity was evaluated by Pharmacological Investigation – Inhibition of protein denaturation using bovine serum albumin with 0.45 ml of bovine serum albumin (5% aq. solution)…

Quantitative assessment of invasiveness serves as a fundamental prerequisite for elucidating the driving mechanisms behind successful invasions of invasive alien plants (IAPs). However, a standardized, comprehensive, and operationally feasible methodology for quantifying the relative potential invasiveness of IAPs remains underdeveloped. This study aims to establish a comprehensive methodology that enables convenient, operational, and feasible quantification of the relative potential…

Background: The accidental inhalation of scarf pins, a growing and preventable respiratory emergency, predominantly affects veiled Muslim women who hold pins in their mouths while adjusting headscarves. This unique cultural hazard poses significant diagnostic and therapeutic challenges and has important public health implications.

Objective: To present our institutional experience with scarf pin inhalation over a 32-year period, detailing the…

Background: Osteoid osteoma is a benign osteoblastic neoplasm accounting for approximately 10–12% of benign bone tumors. It commonly affects the femur and tibia in adolescents and young adults. Proximal humeral involvement is uncommon and may mimic more prevalent causes of shoulder pain, resulting in delayed diagnosis.

Case Presentation: A 17-year-old male presented with a six-month history of persistent right upper arm pain that was more…

The influence of absorption in the shell material on the amplitudes of lines of the TE and TM polarized whispering gallery modes (WGMs) in the emission spectrum of a microresonator structure consisting of a spherical core covered with a luminescent shell with a refractive index greater than that of the core was investigated. The luminescence spectra, radial field distribution and WGM parameters were calculated using the spherical wave transfer matrix method. It is shown that, for different…

Urolithiasis is the most prevalent global urological disorder characterized by the formation of urinary calculi resulting from super saturation and crystallization of minerals such as calcium oxalate, calcium phosphate, uric acid, struvite and cystine. Its incidence varies significantly across regions due to dietary habits, climate, genetic predisposition and metabolic abnormalities. This review aims to provide an updated understanding of the epidemiology, chemical types and etiological…

Background: Forensic microbiomics is an emerging discipline that investigates the use of human associated and environmental microbial communities as complementary sources of forensic evidence. The recent development of next-generation sequencing, metagenomics, bioinformatics and computational biology has expanded the possibility to use microbiome analysis for forensic investigations, providing valuable biological information beyond conventional DNA…

The Schawlow–Townes limit established spontaneous emission as the fundamental quantum mechanism defining the minimum linewidth of an ideal laser oscillator. According to this description, random phase perturbations introduced by spontaneous photons become progressively less significant as the intracavity photon population increases, resulting in a continuous narrowing of the emission linewidth with increasing optical power.

Although this relation remains a cornerstone of laser…

Electrical engineering has emerged as one of the most influential disciplines supporting environmental sustainability in the twenty-first century. The increasing urgency of climate change, resource depletion, energy insecurity, and environmental degradation has highlighted the need for innovative engineering solutions capable of facilitating the transition towards low-carbon and sustainable societies. This paper examines the role of electrical engineering as a catalyst for environmental…
