Essential oils offer a viable alternative to traditional agrochemicals, mitigating problems such as environmental contamination and weed resistance. However, application faces challenges such as low solubility in water and rapid environmental degradation. To overcome these limitations, nanoemulsions containing essential oils from Piper amalago L.

Parasites can influence host physiology and behavior, often impairing cognition. We investigated how infection and parasite load affect olfactory learning and memory in the paper wasp Polistes dominula workers parasitized by the insect parasite Xenos vesparum (Strepsiptera). We adapted a Pavlovian conditioning assay based on the proboscis extension reflex protocol.

Objective: To evaluate factors influencing the response to periodontal therapy in patients with periodontitis and type 2 diabetes mellitus (DM) using machine learning (ML) techniques, considering periodontal parameters, metabolic status, and demographic characteristics.

Methodology: We applied machine learning techniques to perform a post hoc analysis of data collected at baseline and a 6-month follow-up from a randomized clinical trial (RCT). A leave-one-out cross-validation strategy was used for model training and evaluation.

Objective: To analyze and compare the effects of 2 aquatic exercise protocols on the gait of children with cerebral palsy (CP), aged 6 to 8 years.

Methods: A randomized, controlled, and blind clinical trial, carried out with 16 children with CP classified to Gross Motor Function Classification System (GMFCS) II and III bilateral spastic, divided into a group of aquatic balance exercises group (BG) and a group of aquatic trunk exercises group (TG). The following assessments were completed before and after the intervention: 6-Minute Walk Test (6MWT), Trunk Control Measurement Scale, Pediatric Balance Scale, Timed Up and Go, Dynamic Gait Index, and Child Health Questionnaire-Parent form 50.

This paper focuses on the impacts of climate change on vulnerable ecosystems and its implications for the health and well-being of populations. It specifically examines the semi-arid region of Brazil, where the introduction of a social climate adaptation tool, cisterns, has brought about significant positive changes. Cisterns, a low-cost climate adaptation technology, can be replicated globally, reducing the negative health impacts of frequent droughts, especially for vulnerable groups in remote rural areas.

The mechanical properties of cell scaffolds are strongly influenced by their hydration state. In this study, we investigated the effect of the aqueous phase on the elastic modulus of chitosan hydrogel films using two complementary techniques: uniaxial tensile testing and atomic force microscopy (AFM) nanoindentation. Our results demonstrate that hydration markedly reduced the elastic modulus, decreasing from approximately 2 GPa in dry films to 120 kPa in swollen films, primarily due to the plasticizing effect of water.

Neuropeptides are crucial molecules in the nervous system, regulating various biological processes. Neuropeptide F (NPF) and its shorter form, short neuropeptide F (sNPF), serve functions in invertebrates analogous to those of neuropeptide Y (NPY) in vertebrates, modulating growth, reproduction, nociception, circadian rhythms and feeding behaviours. In the honeybee, a social insect that adjusts foraging strategies based on colony needs, sNPF is a key regulator of foraging-related behaviours, including food intake, sucrose sensitivity, olfactory perception and visual memory formation.

Chronic, non-resolving inflammation is a major contributor to impaired wound healing in diabetes. Annexin A1 (AnxA1), a pro-resolving mediator, and its mimetic peptide Ac have demonstrated therapeutic potential in modulating inflammatory responses. In this study, we evaluated the effects of topical Ac hydrogel in a streptozotocin-induced diabetic wound model.

Unlabelled: Skeletal muscle changes occur in heart failure (HF). Despite the cardioprotective effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors in HF, their impact on skeletal muscle remains poorly understood. We investigated the effects of the SGLT2 inhibitor empagliflozin (EMPA) on cardiac remodeling and the soleus muscle of rats with myocardial infarction (MI)-induced HF.

Background: Botulinum toxin (BTX) is considered an efficient and safe therapy for postoperative scars that improves visual and functional quality. However, the optimal timing for injection remains under debate due to conflicting evidence.

Objective: The aim of this study is to evaluate the efficacy and safety of BTX applied immediately after wound closure in the quality assessment of postoperative scars.

Background: Clinical records often provide information on a person's functioning (activities), reflecting their lived experience of health. Automated extraction using clinical natural language processing (cNLP) can assist providers with clinical decision-making, treatment planning, predicting health outcomes, and informing health care policy.

Objective: We aim to (1) describe the applicability of the World Health Organization's International Classification of Functioning, Disability and Health (ICF) to development of cNLP tools, (2) identify key challenges in application of the ICF, and (3) offer recommendations to improve this process.

Introduction: This scoping review aimed to provide an overview of neuromusculoskeletal models used to investigate the mechanisms underlying spasticity and identify issues to be addressed in future models.

Materials And Methods: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR) guidelines and searched four bibliographic databases (PubMed, Compendex Engineering Village, IEEE Xplore, and Science Direct). Inclusion criteria were original studies written in English that investigated the underlying mechanisms of spasticity in humans with no age restrictions.

The most commonly used techniques in the field are the pulmonary auscultation, Wisconsin score (WI), California score (CA), and pulmonary ultrasonography. However, with the exception of the latter, no studies have compared thoracic radiography with other possible techniques in calves. Therefore, the objective of the study was to compare and verify the agreement between clinical score techniques, pulmonary auscultation, and ultrasonographic and radiographic evaluations, considering the latter as reference test.

Biochars (BC) obtained from biomass residues have been highlighted in electroanalytical applications for their distinct physicochemical properties and for making the devices cheaper and sustainable. In this work, we propose the use of BC derived from forest residues of eucalyptus, decorated with cobalt ferrite (CoFeO), as a modifying agent for carbon paste electrodes aimed at the voltammetric sensing of paracetamol (PAR) in biological fluids. BC was obtained by pyrolysis (450 °C, 72 h) and then decorated with CoFeO synthesized co-precipitation.

Nanotechnology offers promising new avenues for combating drug-resistant pathogens. Given its antioxidant capacity, the water-soluble fraction of Brazilian kefir was hypothesized to serve as an effective reducing agent for the green synthesis of silver nanoparticles (AgNPs). It was further hypothesized that both the entire fraction (WSF) and the < 10 kDa fraction AgNPs would augment the therapeutic effects of kefir, particularly its antimicrobial activity.
