Performance and emission analysis of a diesel engine fueled with rice-bran and lemon-peel oil biodiesel blends

The growing demand for sustainable energy and for emission reductions has intensified the search for alternative fuels for compression-ignition engines. This study presents a novel experimental investigation of the combined use of eco-friendly biodiesel derived from rice bran oil...

Interpretable machine learning for identifying mild cognitive impairment among Chinese patients with obstructive sleep apnea: a multicenter cross-sectional study

Mild cognitive impairment (MCI) is clinically relevant in obstructive sleep apnea (OSA). We developed and externally validated an interpretable machine-learning model for concurrent clinically defined MCI to support prioritization for formal cognitive assessment rather than diagn...

The effect of resveratrol on the hippocampus in the pentylenetetrazol (PTZ) - dependent kindling model of epilepsy

Epilepsy is a long-term neurological condition marked by neuronal excitotoxicity, oxidative stress, and inflammation of the nervous system. This study seeks to explore the neuroprotective and anti-seizure properties of Resveratrol (RSV) and the molecular processes involved in a p...

Intrafamilial phenotypic variation in four Palestinian siblings with CFAP418-related ciliopathy: a familial case series

Biallelic CFAP418 variants cause retinal degeneration with variable extraocular findings. The principal contribution of this familial case series is a comparison of four affected siblings carrying the same previously reported splice-donor variant, with explicit separation of orig...

Bidirectional modification effects of non-optimal temperature and short-term exposure to fine particulate matter on cardiovascular mortality and their different subtypes: a time-stratified case-crossover study in multiple cities

Both fine particulate matter (PM 2.5 ) and non-optimal temperatures are well-recognized environmental hazard factors for cardiovascular diseases (CVD). However, the bidirectional modifying effects of these two factors on CVD mortality remain systematically understudied, particula...

Pacing and effort distribution in Hyrox® PRO athletes: differences by sex and performance level

Hyrox ® has rapidly grown into one of the most popular High-Intensity Functional Training (HIFT) competitions, combining running and strength-based stations in a comparatively standardised format. Although pacing and effort distribution are established determinants of performance...

Exploration and evaluation of “1 + N” paired teaching mode for resident physicians and medical interns

To explore and evaluate the mode of “1 + N” paired teaching for resident physicians and medical interns, in order to optimize the effect of both resident training and internship. A total of 72 residents and 162 interns rotating in the same period in the department of Gastroentero...

Assessment of digital technology adoption for cultural heritage preservation in Southwestern Nigeria

The study explores the impact of technology on the preservation and promotion of cultural heritage in Southwest Nigeria. This study used a mixed-methods approach, incorporating qualitative and quantitative methods to gather comprehensive data. The qualitative data collection invo...

Diffuse-interface lattice Boltzmann simulation of nanofluid cooling for advanced battery thermal management

A diffuse-interface lattice Boltzmann model (DI-LBM) is developed for cylindrical lithium-ion battery packs cooled by Al 2 O 3 / H 2 O nanofluids. A double distribution function (DDF) solves the flow and the temperature together on a uniform Cartesian grid, so heat passes correct...

Multiple organic acid-rich fermented wheat bran improves duck meat quality: insights from physicochemical, sensory, and metabolomic properties

Fermented feed improves nutrient digestibility and enhances beneficial microbial activity, leading to better animal growth and meat quality. The aim of this study was to investigate the effects of acid-rich fermented wheat bran GMAS2S3 supplementation on the meat quality and meta...

Quality verification of hepatitis C surveillance data in a high-volume tertiary center in Chaoyang District, Beijing, 2023

To assess the current status of hepatitis C case reporting quality at a designated hepatitis C treatment institution in Chaoyang District, Beijing, identify problems in data reporting, standardize the reporting practices of the study institution, and provide evidence for improvin...

Mental well-being and associated factors among performing artists in Kathmandu Metropolitan City, Nepal: a cross-sectional study

Abstract Background Performing artists are exposed to unique occupational stressors, including irregular employment, financial insecurity, competitive work environments, and unstable professional opportunities, which may adversely affect mental well-being. Despite growing recogni...

Modifiable risk factors, tenofovir use and incident chronic kidney disease among people with HIV and people without HIV

The association of modifiable risk factors with incident chronic kidney disease (CKD) among persons with HIV (PWH) and without HIV (PWoH), including alcohol use disorder, diabetes, dyslipidemia, hypertension, smoking, and potentially tenofovir (alafenamide compared with disoproxi...

Are collapsible bicycle helmets as protective against head injuries as conventional designs?

Collapsible bicycle helmets address portability as a barrier to helmet use, particularly for bicycle share scheme users, but whether they provide equivalent protection to conventional helmets is unknown. We determined whether head injury risk differs between designs and whether a...

Bilateral lower extremity lymphedema-like swelling associated with a painless femoral trochanteric fracture in an older patient: a case report

Femoral trochanteric fractures in older adults usually cause hip pain, but they may present atypically with acute immobility and no pain, leading to delayed diagnosis. We report an older patient in whom a painless femoral trochanteric fracture was initially misattributed to seque...

Association between glycemic management during pregnancy and postpartum metabolic health outcomes among women with gestational diabetes mellitus

Abstract Background Glycemic management is standard for gestational diabetes mellitus (GDM), yet its impact on postpartum metabolic health, especially in late-onset GDM, remains uncertain. Objective To assess whether achieving glycemic control during pregnancy improves postpartum...

Tuning bioactive compound recovery from Chlorella vulgaris through surfactant-assisted ethanol extraction under microwave and pressurized liquid technologies

Chlorella vulgaris is a promising source of bioactive compounds such as polyunsaturated fatty acids (PUFAs), pigments, and antioxidants, whose recovery strongly depends on extraction conditions. In this context, surfactant-assisted extraction remains poorly explored for microalga...

Mobility creates reach, ecosystems determine conversion: Founder educational mobility and international engagement

Founder educational mobility is often treated as a channel through which entrepreneurs access non-local knowledge, networks, and opportunities. Yet mobility may not automatically translate into international market engagement. The key insight of our study is that mobility creates...

Grazing intensity regulates cattle movement and forage-use-efficient behavioral patterns through vegetation and abiotic pathways in a temperate meadow steppe

Livestock movement and time allocation are key behavioral processes linking grazing pressure to grassland use efficiency, yet how these behaviors respond to quantified grazing intensity and associated vegetation and abiotic conditions remains insufficiently understood. In this st...
