Plant sphingolipids are lipophilic membrane components essential for different cellular functions but they also act as signaling molecules in various aspects of plant development. However, the interaction between plant sphingolipids and abscission remains largely uncharacterized. Here, the possible role of sphingolipids in regulating fruit abscission was examined in the abscission zone (AZ) of olive fruit.

Background: Perinatal growth and nutrition have been shown to be determinants in the programming of different tissues, such as adipose tissue, predisposing individuals to metabolic alterations later in life. Previous studies have documented an increased risk of metabolic disturbances and low-grade inflammation in prepubertal children with a history of extrauterine growth restriction (EUGR). The aim of this study was to evaluate possible alterations resulting from impaired growth during early childhood and their impact on young adult health.

Introduction: A positive surgical margin (R1 resection) is a relevant risk factor for local recurrence in patients with pancreatic ductal adenocarcinoma of the pancreas (PDAC). An intraoperative liquid biopsy (ILB) based on tumor cell mobilization could help to detect R1 resection intraoperatively.
Objective: To evaluate the potential role of the intraoperative circulating tumor cells (CTCs) and cluster mobilization on the R0/R1 detection.

Monitoring the dynamics of contaminants in ecosystems helps understand their potential effects. Seabirds have been used as biomonitors of marine ecosystems for this purpose. However, exposure and vulnerability to pollutants are understudied in tropical species, and the relationships between various pollutants and the trophic ecology of seabirds are poorly understood.

Purpose: The aim of this study was to propose a lateral oscillating device for the prevention of pressure ulcers by understanding the mechanisms of tissue protection in healthy individuals during prolonged decubitus. We also sought to determine the optimal time interval for oscillation, considering peak pressure peaks and tolerable pressure limits as a function of individual characteristics such as age, weight, height, gender, and BMI.
Methods: A quasi-experimental, descriptive and analytical observational study was conducted between January 2022 and June 2023 with a sample of 25 healthy volunteers.

Livestock grazing and trampling have been shown to reduce arthropod populations. Among arthropods, defoliating lepidopterans are particularly important for their impact on trees, the keystone structures of agroforestry systems. This study investigates the impact of livestock on the community of defoliating lepidopterans in agroforestry systems.

Creatine monohydrate supplementation is widely used by athletes in high-intensity, power-based sports due to its ability to enhance short-term performance by increasing intramuscular phosphocreatine (PCr) stores, which aid in ATP resynthesis during intense muscle contractions. However, emerging evidence suggests that creatine monohydrate offers benefits beyond athletic performance. This narrative review explores the literature supporting the advantages of creatine supplementation in women, vegans, and clinical populations.

Objectives: This study aimed to compare the psychological demands and external workload experienced in the seven sessions leading up to injuries and the demands in the month preceding the injury week among professional Brazilian soccer players.
Methods: Initially, 33 players participated, but only 15 were included in the analysis due to the occurrence of twenty-three muscle-tendon injuries recorded according to International Olympic Committee (IOC) guidelines. The study assessed muscle-tendon injuries, rate of perceived exertion (RPE), and psychological variables (i.

In three-dimensional (3D)-printed tissue models, sensitive, noninvasive techniques are required to detect changes in hydrogel structure caused by cellular remodeling. We demonstrate herein that circular dichroism (CD) spectroscopy provides a reliable method for detecting hydrogel structural variations. We probe directly the plasmonic optical activity of chiral gold nanorods (c-AuNRs) embedded within the hydrogel matrix, in response to variations in the local environment.

The paradigms of Industry 4.0 and Industrial Internet of Things (IIoT) require functional architectures to deploy and organize hardware and software taking advantage of modern digital technologies in industrial systems. In this sense, a lot of the literature proposes and describes this type of architecture with a conceptual angle, without providing experimental validation or with scarce details about the involved equipment under real operation.

Many clinical, neuroimaging, neuropathological, epidemiological, and genetic data suggest a relationship between essential tremor (ET) and Parkinson's disease (PD). Several hypothesis-based gene association studies attempted to find a genetic association between these diseases. Recent case-control association studies in Chinese and Spanish populations showed a marginal association between the rs1922452 and rs951818 single nucleotide variants (SNVs) and the risk of PD.

Filamin A (FLNA) is an actin-binding protein that has been reported to interact with STIM1 modulating the activation of Orai1 channels. Cleaving of FLNA by calpain leads to a C-terminal fragment that is involved in a variety of functional and pathological events, including pro-oncogenic activity in different types of cancer. Here we show that full-length FLNA is downregulated in samples from colon cancer patients as well as in the adenocarcinoma cell line HT-29.

Diabetes mellitus (DM) is one of the most common chronic endocrine diseases, characterized by hyperglycemia, due to abnormal nitric oxide synthesis. The trend of an increase in the number of patients with DM continues. The medical and economic burden of DM is not only associated with hyperglycemia management but also with the management of DM-related complications.

The ubiquitin E2 variant domain of TSG101 (TSG101-UEV) plays a pivotal role in protein sorting and virus budding by recognizing PTAP motifs within ubiquitinated proteins. Disruption of TSG101-UEV/PTAP interactions has emerged as a promising strategy for the development of host-oriented broad-spectrum antivirals with low susceptibility to resistance. TSG101 is a challenging target characterized by an extended and flat binding interface, low affinity for PTAP ligands, and complex binding energetics.

Mental health promotion and substance use prevention are essential issues at universities worldwide. Although research has identified risk and protective factors for substance use generally among college students, there is a paucity of knowledge about anxiolytic use. Thus, the main objective of this study was to analyze if prescription and non-prescription anxiolytic use was related to self-control, self-esteem and self-efficacy.

Alders are widely distributed riparian trees in Europe, North Africa and Western Asia. Recently, a strong reduction of alder stands has been detected in Europe due to infection by species (Stramenopila kingdom). This infection causes a disease known as alder dieback, characterized by leaf yellowing, dieback of branches, increased fruit production, and bark necrosis in the collar and basal part of the stem.
