Antimicrobial and antioxidant activity of Zataria multiflora essential oil and its delivery systems in food

Zataria multiflora , known as Avishane Shirazi (Shirazi thyme) or Persian thyme, is one of the most popular aromatic and medicinal plants in Iran. Zataria multiflora essential oil (ZEO) has been reported to have various biological activities. The studies showed that ZEO had signi...

A Generalized Order-Reduction Method for Transfer Function and Pole–Zero Analysis of Linear Analog Circuits

Accurate pole–zero determination is essential for predicting the frequency response, stability, and bandwidth of analog circuits. Conventional transfer function derivations based on nodal or mesh analysis, however, often produce lengthy symbolic expressions and provide limited ph...

Two millennia of Caspian Sea level change and Hyrcanian forest dynamics: A multi-proxy record from the Anzali Lagoon, northern Iran

A multi-proxy study of a 5-m-long sediment core from the Anzali Lagoon (southwest Caspian coasts) was conducted to reconstruct Caspian Sea level fluctuations and concurrent vegetation history in the Hyrcanian forests over the past two millennia. The record reveals several major t...

Synergistic regulation of yield and fruit quality in plum through combined application of mycorrhizal fungi and a tri-species leaf extract bio-stimulant

Despite the established benefits of mycorrhizal fungi and botanical biostimulants, their synergistic effects on fruit crop quality and productivity remain insufficiently characterized. This study evaluated the combined application of three mycorrhizal species ( Rhizophagus irregu...

Harnessing stem cell-based therapies for Alzheimer’s disease: mechanism, challenges, and future perspectives

Alzheimer’s disease (AD) affects more than 55 million people worldwide, and current pharmacological treatments provide only modest symptomatic benefits with limited effects on disease progression. Stem cell-based therapies, including mesenchymal stem cells (MSCs), neural stem cel...

Prediction of fast, slow, and average shear-wave velocities from well logs using artificial neural networks and statistical regression

Abstract Accurate estimation of fast, slow, and average shear-wave velocities (Vs Fast , Vs Slow , and Vs Average ) is important for evaluating reservoir anisotropy, fracture networks, and stress regimes. In this study, multivariate statistical regression and artificial neural ne...

Mineralogical and geochemical constraints on high-sulfidation epithermal alteration in the Zamharir kaolin deposit, northwestern Iran

The Zamharir kaolin deposit in northwestern Iran represents hydrothermal alteration of the Oligocene andesitic rocks within a high-sulfidation epithermal system. Mineralogical assemblages display conspicuous spatial zonation, with kaolinite, alunite, pyrite, and rutile concentrat...

Shift in streamflow seasonality and regime due to precipitation variability in a snow-influenced mountainous watershed

Abstract In mountainous regions, water availability and flood hazards are tightly linked to the timing and seasonality of streamflow, making their analysis indispensable for sustainable resource planning. In this regard, this study examines changes in seasonality and precipitatio...

Bifidobacterium longum prevent the progression of colon cancer via inhibiting metastasis and angiogenesis

Colorectal cancer (CRC) is one of the most common reasons for cancer-related death, and both angiogenesis and metastasis have established roles in CRC progression. Recent findings suggest that probiotics, like Bifidobacterium longum, are capable of suppressing anti-cancer activit...

Prevalence of hyperthyroidism in infertile women referred to assisted reproductive technology centers affiliated with Urmia University of Medical Sciences: a retrospective cross-sectional study

Abstract Background Thyroid dysfunction, particularly hyperthyroidism, is a recognized modulator of female fertility, yet its prevalence among infertile women remains inadequately characterized. This study aimed to determine the prevalence of biochemical hyperthyroidism among inf...

Comparing the effects of PETTLEP imagery and mindfulness interventions on passing and goal-kicking performance in male novice soccer players (Ages 10–14): A randomized controlled study

Psychological interventions such as PETTLEP imagery and mindfulness have been associated with improvements in motor skill performance and skill acquisition in sports. However, their comparative effects on passing and goal-kicking performance in youth soccer players remain unclear...

Salinomycin modulates viability, invasion, and inflammatory responses in primary endometriotic stromal cell cultures in association with Wnt/β-catenin signaling

Endometriosis is a chronic inflammatory disorder characterized by aberrant stromal-cell behavior, including enhanced invasion, resistance to apoptosis, and sustained cytokine production. Dysregulation of Wnt/β-catenin signaling has been linked to these pathological features, emph...
