Synthesis and biological characterization of formononetin derivatives against phytopathogenic oomycete and bacteria: preliminary mechanisms, theoretical predictions, and biosafety evaluation

Abstract Background The increasing prevalence of phytopathogenic oomycetes and bacteria, particularly Phytophthora capsici ( Pc ) and Xanthomonas oryzae pv. oryzae ( Xoo ), poses severe threats to global agricultural production. Developing novel antimicrobial agents with dual ant...

Design and Development of an Automated Surface Tension Analyzer Based on Bubble Pressure Variations

A low-cost, automated surface tension analyzer was designed and developed based on the maximum bubble pressure method. The system measures the pressure required to form air bubbles through a capillary immersed in a liquid, allowing the surface tension to be determined from the pr...

Balanced Animal Nutrition for Better Feeds, Healthy Animals, Safe Food, and a Healthy Planet: A One Health Perspective—An Invited Review

Livestock production is increasingly expected to deliver not only higher output, but also better animal health and welfare, safer and more nutritious food, viable livelihoods, and lower environmental pressure. This invited review examines balanced animal nutrition within a One He...

Adolescent pregnancy and adverse maternal and perinatal outcomes: a systematic review and meta-analysis

Adolescent pregnancy remains a major global public health concern, yet evidence on its association with a broad range of maternal and perinatal outcomes remains fragmented. We conducted a systematic review and meta-analysis of observational studies comparing adolescents (13–19 ye...

Beyond Regulatory Thresholds: Continuous and Explainable Assessment of Vehicle Emission Condition

Vehicle emission testing commonly evaluates regulatory compliance using predefined thresholds and pass/fail outcomes, providing limited information about differences in multivariate emission condition. This study develops a vehicle emission assessment framework combining hierarch...

Steel Inter-Modular Connections for Resilient and Sustainable Modular Buildings: A Structured Comparative Review and Design Framework

Inter-modular connections (IMCs) govern the structural performance, safety, seismic resilience, and reusability of steel modular buildings, yet the existing literature on advanced IMC systems remains fragmented and connection-specific. This paper presents a comparative review of...

Seasonal Gut Microbiome Variation Associated With Both Climate and Wildlife Tourism in Asian Elephants ( Elephas maximus )

The health, survival, and fitness of wild animals depend on their responses to seasonal variation in natural and anthropogenic environmental factors. The gut microbiome is a unique, non-invasive tool for assessing the magnitude of these responses, but few studies collect longitud...

Quality Characteristics and Functional Properties of Paneer Fortified with Sesbania grandiflora Leaf Powder

Sesbania grandiflora (Agathi) is a nutritionally and pharmacologically rich tropical legume tree whose leaves contain substantial quantities of phenolic acids, flavonoids, carotenoids, calcium, and iron. Despite their well-documented bioactivity, comprehensive multi-parameter cha...

Trends in Incidence and Mortality of Oral Cancer in Sri Lanka 2005-2022: A Population-Based Temporal Analysis

INTRODUCTION: Lip and oral cavity cancer (LOCC) is a major global health burden, disproportionately affecting South and South-East Asia, including Sri Lanka, where tobacco use, betel quid chewing, and alcohol consumption remain key risk factors. Despite its preventable nature, in...

Massive non-surgical hemorrhage induced by amniotic fluid embolism during cesarean hysterectomy for placenta percreta with placenta previa: a case report

Amniotic fluid embolism (AFE) can give rise to disseminated intravascular coagulation (DIC), which can result in life-threatening obstetric hemorrhages. There are no reported cases where sudden onset massive pulmonary and intestinal hemorrhages were the main mode of blood loss du...

Patient perceptions of physician attire and perceived infection risk associated with attire and grooming in outpatient care at a tertiary care hospital in Central Sri Lanka

Physicians’ attire is a visible aspect of clinical care and may influence patients’ trust, confidence, and perceived safety. Evidence from outpatient settings in low- and middle-income countries remains limited. To describe patients’ perceptions of physicians’ attire, grooming an...

A salutogenic mobile health application for adolescent oral health: development and feasibility study

The health model of salutogenesis, has the potential to develop and implement digital health interventions, many of which are focused on self-care. Sense of coherence and generalized resistance resources are two key concepts of the health model of salutogenesis. The aim of this s...
