A step forward to exploring the inhibitory effects of crude honey bee venom (Apis mellifera) and its derived phospholipase A2 (bvPLA2) against Leishmania major in vitro

Leishmaniasis is a widespread parasitic disease with cutaneous, mucocutaneous, and visceral forms. Despite longstanding recognition, effective treatment remains a challenge due to limitations of current chemotherapies, including toxicity and resistance. Natural toxins, particular...

Explainable machine learning for shear capacity prediction of reinforced concrete deep beams

The shear capacity prediction of reinforced concrete (RC) deep beams remains a challenging issue in design of concrete structures. Although the code-based strut-and-tie method is widely accepted, it is often time-consuming for routine design applications, while existing empirical...

Effects of dynamic neuromuscular stabilization with and without immersive virtual reality on pain, postural, and functional outcomes in women with lumbar hyperlordosis and chronic non-specific low back pain: a randomized controlled trial

Lumbar hyperlordosis is a common postural abnormality in women and is often associated with chronic non-specific low back pain (CNLBP). This condition is linked to functional impairments and reduced physical performance. Dynamic Neuromuscular Stabilization (DNS), which emphasizes...

Targeting ferroptosis in cancer: molecular mechanisms and emerging therapeutic strategies

Ferroptosis, an iron-dependent form of regulated cell death characterized by the lethal accumulation of lipid peroxides, has emerged as a pivotal pathway in cancer biology and a promising therapeutic target. This review synthesizes the core molecular machinery governing ferroptos...

The hidden cost of dormancy: redefining facility management strategies for seasonal homes

Purpose Although seasonal homes make up a large and growing part of the built environment, facility management (FM) requirements have been neglected. This study aims to fill this critical gap, challenge the common principle that function is the agent of deterioration and explain...

Listen to my play: Decoding the narratives and emotions of sexually abused children through a mixed-methods approach

Background Child sexual abuse (CSA) is a prevalent yet underreported problem, and reliable tools for assessing its psychological impact in children remain limited. Objective This study aimed to develop narrative story stems, identify core themes in children's narratives, develop...

Trend analysis of breast cancer screening in Golestan province’s family physician program: performance evaluation for women aged 30–69

In the ranking of cancer incidence for the year, female breast cancer was the most common cancer in the north-east region of Iran. This study aimed to comprehensively evaluate the trend of breast cancer screening within Golestan province’s Family Physician Program. This repeated...

Isolation and identification of usnic acid from Usnea articulata and evaluation of the antioxidant and antibacterial activities of its ethanol and acetone extracts

Abstract In this study, the antioxidant and antimicrobial activities of Usnea articulata were investigated, and usnic acid was isolated and structurally characterized. Antioxidant activity and total phenolic content were evaluated in acetone and ethanol extracts of the species us...

Structural rejuvenation and mechanical resilience of CuZr metallic glasses under ion irradiation using molecular dynamics simulations

Molecular dynamics simulations were conducted to investigate the structural and mechanical response of CuZr metallic glasses (MGs) under ion irradiation. Amorphous models of Cu 64 Zr 36 , Cu 50 Zr 50 , and Cu 46 Zr 54 were prepared and subjected to primary knock-on atoms (PKAs) w...

Advancing asparaginase-based therapy for acute lymphoblastic leukemia through computational immunoengineering and molecular dynamics simulations
