Acute Ethanol Exposure Inhibits GABA Uptake in Embryonic Chicken Retina

Abstract GABA is the major inhibitory amino acid in the central nervous system (CNS), and its homeostasis is crucial for inhibitory/excitatory balance. Its reuptake is mediated by GABA transporters, including type 1 (GAT-1), a high-affinity GABA plasma membrane transporter. Ethan...

A transformer-based framework for device-free human activity recognition using Wi-Fi CSI

Abstract Human activity recognition (HAR) plays a pivotal role in ambient assisted living, particularly for monitoring the elderly and patients with chronic conditions. However, traditional approaches relying on wearable sensors or video cameras face significant challenges regard...

A Novel Radiographic Classification of the Proximal Tibiofibular Joint

Background and Objectives: We aim to develop a simple radiographic classification for describing the morphological inclination of the proximal tibiofibular joint (PTFJ) based on composite measurements obtained from standard anteroposterior and lateral knee radiographs, and to eva...

Peptidomic Characterizationand Functional Propertiesof Goat and Cow Milk Kefir before and after In Vitro Digestion

Abstract Kefir is a fermented beverage produced from goat or cow milk. This study evaluated the bioactive potential and peptidomic profile of kefirs from both species before and after in vitro digestion. Peptides from undigested, gastric, and intestinal phases were characterized...

A lean-based method for patient journey improvement: enhancing value and performance in healthcare delivery

Purpose This research introduces a lean-based method, from the customer’s perspective, aimed at continuously improving the sequence of value and non-value stages throughout the purchase journey, named the ideal customer journey method (ICJM). Design/methodology/approach The ICJM...

Optimizing diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide concentration and post‐curing time to balance mechanical properties and color stability in a three‐dimensional‐printed restorative resin

Abstract Three‐dimensional (3D) printing is widely used in dental restorations; however, optimization of photoinitiator concentration and post‐curing protocols remains critical to achieve a balance between mechanical and esthetic performance. This study evaluated the combined eff...

Endovascular therapy versus best medical treatment in pediatric acute ischemic stroke: A systematic review and meta-analysis

Purpose This systematic review and meta-analysis evaluates endovascular therapy (EVT) versus best medical treatment (BMT) in pediatric acute ischemic stroke (AIS) due to large-vessel occlusion. Methods Systematic searches were conducted across PubMed, Cochrane, and Embase, incept...

From seeds to plant-based milk: nutritional and bioactive characterization of munguba (Pachira aquatica) and its derived beverage

Plant-based milks are beverages obtained from aqueous extracts of plant raw materials, exhibiting varied sensory and nutritional properties. Although they can be produced from sources such as cereals, legumes, and oilseeds, expanding the diversity of raw materials is necessary to...

Forensic facial approximation methodologies applied to the Brazilian population: a scoping review

This scoping review aimed to map forensic facial approximation (FFA) methodologies applied to the Brazilian population. The protocol was registered in the Open Science Framework and adopted the following structure: Population, human; Concept, FFA methodologies; and Context, studi...

Data-driven Bayesian Network structure learning for probabilistic inference of rainfall in Rio de Janeiro

Abstract Bayesian Networks (BNs) provide an interpretable probabilistic framework for modeling uncertainty in complex environmental systems. This study proposes a data-driven Bayesian Network (BN) to represent probabilistic relationships among meteorological variables and precipi...

From crisis response to everyday work: Exploring resilient capacities in health systems’ governance and frontline operations

Background This scoping review examines health system resilience, shifting the focus to beyond crisis response to include everyday adaptation, governance, and transformative capabilities in universal health systems. Objectives Describe and analyze health system resilience framewo...
