Cocoa seed extract induces antiproliferative and pro-apoptotic effects in HT-29 colorectal cancer cells

The beneficial therapeutic actions of cocoa (Theobroma cacao L.) in the treatment of cancer, attributed to antioxidant and anti-inflammatory properties, are well-established. The aim of this study was to investigate the anticarcinogenic effect of cocoa on colorectal cancer cells...

One-step production and physicochemical characterization of biodiesel using rubber seed oil blends

Abstract The seeds of Hevea brasiliensis (HB) stand out as a promising feedstock for biodiesel production owing to their high oil content. However, its elevated acid value poses a challenge, requiring pre-treatment steps before transesterification. Given this scenario, the presen...

Evolution of the axial skeleton of early dinosaurs and the role of meristic and homeotic processes

Abstract Changes in the axial skeleton played an important role in dinosaur evolution, with some of the oldest dinosaurs showing evidence of sacralization events. The increased number of early dinosaur discoveries over the last decade provides an opportunity to better characteriz...

Green dynamic capabilities, climate change management, and business performance: evidence from metal-mechanical industries in Southern Brazil

This study examines how green dynamic capabilities, understood as a firm's capacity to sense environmental change and to integrate and reconfigure resources in response to it, influence climate change management and business performance in metalworking industries. A survey of top...

Spatially Extensive Snapshot Sampling Reveals Regional Turnover and Complements Temporal Surveys of Drosophilidae in Southern Brazil

Sampling design strongly influences which components of biodiversity are recovered in regional inventories. We evaluated a spatially extensive snapshot survey of Drosophilidae assemblages in southern Brazil and compared it with temporally repeated datasets from the same broad reg...

Breaking the Blend: A multi-tracer kinematic decomposition method for IFS data applied to disentangling the AGN outflow and circumnuclear ring in NGC 5728 with JWST

Abstract Integral field spectroscopy (IFS) of the central kiloparsecs of active galactic nuclei (AGN) reveals a mixture of spatially coincident emission from star-formation and AGN feedback exciting the interstellar medium. Disentangling these components remains a challenge, as m...

Combined effects of kombucha consumption and aerobic exercise on oxidative stress and metabolic parameters in Wistar rats

Abstract Background Kombucha, a fermented tea containing symbiotic bacteria and yeast, and aerobic exercise each confer distinct health benefits, but their combined effects remain poorly understood. This study investigated the combined effects of consuming kombucha fermented for...

Anatomopathological and toxicological analysis of a dog poisoned with methomyl

Abstract A dog with suspected poisoning was submitted for postmortem examination. Generalised visceral congestion was observed in the abdominal cavity, with the liver, kidneys and gastrointestinal tract most severely affected. However, there was no macroscopic evidence of granula...

Influence of Residual Lignin on Mechanical Fibrillation and Colloidal Stability of Cellulose Nanofibrils from Eucalyptus Kraft Pulp

Eucalyptus kraft pulping represents an important source for the production of lignin-containing cellulose nanofibrils (LCNF); however, the influence of controlled residual lignin levels on fibrillation energy demand and suspension stability remains poorly understood. This study e...

Is Sleep Bruxism Associated With General Quality of Life? Insights From the EPISONO Population‐Based Study

ABSTRACT Aim The aim of this study is to evaluate the association between sleep bruxism (SB) and general quality of life (QoL) among adults. Methods This cross‐sectional study was conducted with a sample of 692 adults who completed the WHOQOL‐Bref questionnaire (mean age of 50.1...

SGA-based volleyball teaching with explicit life skills instruction is associated with technical-tactical, psychosocial, and motivational improvements in school students

This quasi-experimental study examined whether a school volleyball unit based on the Step-Game-Approach model combined with explicit life skills teaching (SGA + LS) was associated with changes in technical-tactical performance, life skills, motivation, and perception of success....

A Framework for Supplier Management Based on Environmental, Social, and Governance Criteria for Small and Medium‐Sized Enterprises

ABSTRACT Corporate sustainability, grounded in environmental, social, and governance (ESG) dimensions, has become a strategic imperative for firms seeking competitiveness and resilience. In supply chain management, supplier selection is a key mechanism for translating ESG princip...

Solanum vegetables as potential neuroprotective functional foods in Alzheimer's disease management: A unifying mechanism

Alzheimer's disease (AD) is a multi-etiological neurological condition that requires a holistic therapeutic approach in its management. In view of this functional foods and nutraceuticals have become --promising candidates in AD research. This is because functional foods and nutr...

Echo Intensity Band Analysis for Assessing Skeletal Muscle Quality in Older Women with Type 2 Diabetes and Peripheral Arterial Disease

Background: Type 2 Diabetes Mellitus (T2DM) and Peripheral Arterial Disease (PAD) are associated with impaired skeletal muscle quality; however, the impact of T2DM alone and the additional burden of concomitant PAD on echo intensity (EI) band distribution remain unclear. This stu...

Critical levels and sufficiency ranges of phosphorus in Pinus taeda plantations in southern Brazil

Pinus taeda plantations in South America have been cultivated on soils of low natural fertility, especially phosphorus (P), increasing the necessity for phosphate fertilisation. The proposition of critical levels (CL) and sufficiency ranges (SR) of P in the needles and soil in P....

Minimally Invasive vs Open Surgery for the Treatment of Spinal Spondylodiscitis: A Systematic Review and Meta-Analysis

Background Despite common conservative management for spondylodiscitis, surgical intervention is indicated in specific clinical scenarios. While open techniques are traditionally favored, the role and efficacy of minimally invasive surgery (MIS) vs conventional open approaches re...

Biomass-Waste-Derived Silica for Solvent-Lean Cu-SSZ-13 Porous Catalysts in NH3-SCR NOx Remediation
