Predictors of father-infant attachment security in a Portuguese sample.

A growing literature shows that fathers play a critical role in their children's development and mental health. However, few studies have evaluated fathers as caregivers and attachment figures, particularly across cultures. We address this gap by investigating specific predictors of infant-father attachment patterns during the first year postpartum and their links to infant-father attachment at 12 months.

Success of Strabismus Surgery in Intermittent Exotropia.

: Intermittent exotropia (IXT) is the most common form of childhood divergent strabismus. Surgery remains the primary approach to control ocular deviation and preserve binocular function. Although previous studies report a success rate of approximately 75%, factors influencing surgical outcomes remain insufficiently explored.

Visual and motor skills development in preterm and full-term infants: A protocol for longitudinal data collection.

Preterm birth, defined as birth before 37 weeks of gestation, affects approximately one in ten live-born infants globally. The risks and potential complications are more pronounced in infants born before 32 weeks, particularly those born before 28 weeks, necessitating specialized monitoring of developmental outcomes. Traditional developmental assessments often rely on performance-based observations, which can be subjective, and may not detect subtle or delayed difficulties that emerge later, such as in school-age children.

Overview of Systematic Reviews on Treatments for Pulmonary Arterial Hypertension: Assessing Methodological Quality and Mapping Evidence Gaps.

Health and Psychological Predictors of Antibiotic Use in Infancy and Fathers' Role.

Previous research has shown that antibiotic use during the first year is associated with infants' difficult behavior, maternal low sensitivity, and infant insecure-ambivalent attachment. However, these results may depend on the extent and type of parental involvement, paternal stress related to infant care, or the infant's exposure to infections. To explore this question, we analyzed the relationship between these factors and examined potential predictors of antibiotic use among demographic, health, and psychological variables.

Carbon monoxide affects early cardiac development in an avian model.

Introduction: Carbon monoxide (CO) is a toxic gas that can be lethal in large doses and may also cause physiological damage in lower doses. Epidemiological studies suggest that CO in lower doses over time may impact on embryo development, in particular cardiac development, however other studies have not observed this association.

Methods: Here, we exposed chick embryos in ovo to CO at three different concentrations (3, 9, 18 ppm) plus air control (4 protocols in total) for the first 9 days of development, at which point we assessed egg and embryo weight, ankle length, developmental stage, heart weight, ventricular wall thickness, ventricular-septal thickness and atrial wall thickness.

The Use of Mobile Sensors by Children: A Review of Two Decades of Environmental Education Projects.

Over the past twenty years, the use of electronic mobile sensors by children and youngsters has played a significant role in environmental education projects in Portugal. This paper describes a research synthesis of a set of case studies (environmental education projects) on the use of sensors as epistemic mediators, evidencing the technological, environmental, social, and didactical dimensions of environmental education projects over the last two decades in Portugal. The triggers of the identified changes include: (i) the evolution of sensors, information and communication platforms, and mobile devices; (ii) the increasing relevance of environmental citizenship and participation; (iii) the recognition of the role of multisensory situated information and quantitative information in environmental citizenship; (iv) the cause-effect relation between didactical strategies and environmental education goals; (v) the potential of sensory and epistemic learners' practices in the environment to produce learning outcomes and new knowledge.

Rejuvenating the [1, 2, 3]-triazolo [1,5-a]quinoxalin-4(5)-one scaffold: Synthesis and derivatization in a sustainable guise and preliminary antimicrobial evaluation.

The [1,2,3]-triazolo [1,5-a] quinoxalin-4(5)-one scaffold and its analogues triazole-fused heterocyclic compounds are relevant structural templates in both natural and synthetic biologically active compounds. However, their medicinal chemistry applications are often limited due to the lack of synthetic protocols combining straightforward generation of the central core while also allowing extensive decoration activity for drug discovery purposes. Herein, we report a "refreshed" synthesis of the [1,2,3]-triazolo [1,5-]quinoxalin-4(5)-one core, encompassing the use of eco-compatible catalysts and reaction conditions.

A wide array of lignin-related phenolics are oxidized by an evolved bacterial dye-decolourising peroxidase.

Lignin is the second most abundant natural polymer next to cellulose and by far the largest renewable source of aromatic compounds on the planet. Dye-decolourising peroxidases (DyPs) are biocatalysts with immense potential in lignocellulose biorefineries to valorize emerging lignin building blocks for environmentally friendly chemicals and materials. This work investigates the catalytic potential of the engineered PpDyP variant 6E10 for the oxidation of 24 syringyl, guaiacyl and hydroxybenzene lignin-phenolic derivatives.

Effect of Aqueous Extract of Phenolic Compounds Obtained from Red Wine in Experimental Model of Colitis in Mice.

Background: Inflammatory bowel disease (IBD) is a chronic relapsing inflammatory disorder represented by Crohn's disease and ulcerative colitis. Currently, there is no cure and pharmacological treatment aims to induce and maintain remission on patients. Because the therapy reveals a relatively high toxicity, during a long-term utilization, it is essential to investigate new pharmacological approaches.

Shoulder Related Temperature Thresholds in FSSW of Aluminium Alloys.

Friction Stir Spot Welding (FSSW) is assumed as an environment-friendly technique, suitable for the spot welding of several materials. Nevertheless, it is consensual that the temperature control during the process is not feasible, since the exact heat generation mechanisms are still unknown. In current work, the heat generation in FSSW of aluminium alloys, was assessed by producing bead-on-plate spot welds using pinless tools.

Lack of Consistent Association between Asthma, Allergic Diseases, and Intestinal Helminth Infection in School-Aged Children in the Province of Bengo, Angola.

Epidemiological studies have shown conflicting findings on the relationship between asthma, atopy, and intestinal helminth infections. There are no such studies from Angola; therefore, we aimed to evaluate the relationship between asthma, allergic diseases, atopy, and intestinal helminth infection in Angolan schoolchildren. We performed a cross-sectional study of schoolchildren between September and November 2017.

Functional Food Components, Intestinal Permeability and Inflammatory Markers in Patients with Inflammatory Bowel Disease.

Inflammatory bowel diseases (IBD) are characterized by a chronic inflammatory process that affects the intestinal barrier structure. Recent evidence suggests that some food components can influence the integrity of the intestinal barrier and thus its permeability. We aimed at assessing the effect of food components on the intestinal permeability (IP) and on inflammatory markers in individuals with IBD by a single-blind randomized clinical study.

PET/CT in the Evaluation of Hypoxia for Radiotherapy Planning in Head and Neck Tumors: Systematic Literature Review.

This work consisted of a systematic literature review that included websites, books, and articles dated from July 1997 to December 2019. The aim was to identify the PET radiopharmaceuticals best suited to the detection of cell hypoxia and to recognize the benefits for planning intensity-modulated radiation therapy (IMRT) and volumetric arc therapy (VMAT).

KIMEHS-Proposal of an Index for Qualitative Evaluation of Children's Menus-A Pilot Study.

Considering the importance of the food environments for health promotion, and the lack of simple, easy to use, low-cost measures of the quality of meals, the authors developed a qualitative menu index (KIMEHS-Kids' Menu Healthy Score), tailored to children's menu evaluation. Development of the tool was based on the Mediterranean food pattern. It includes 18 components, divided into seven main groups that reflect key aspects of menu quality, including protein source, side dishes, vegetables, dessert and beverages, and also allergens and nutritional information.

Prolonging fixation time of an alternative fixative to formalin for dermatological samples using standard laboratory protocols.

Aims: Though formalin remains to be the gold standard fixative in pathology departments, analytical challenges persist for nucleic acid evaluations. In our laboratory, formalin fixation of skin samples in particular impairs diagnostic accuracy and demands repetition of biopsies and analytical procedures. PAXgene Tissue Systems may be an alternative; however, according to manufacturer specifications it only allows fixation for 48 hours before having to add a stabiliser.

Helminth infections, atopy, asthma and allergic diseases: protocol for a systematic review of observational studies worldwide.

Introduction: Childhood infections, particularly those caused by helminths are considered to be important environmental exposures influencing the development of allergic diseases. However, epidemiological studies focusing on the relationship between helminth infections and risk of allergic diseases, performed worldwide, show inconsistent findings. Previous systematic reviews of observational studies published 10 or more years ago showed conflicting findings for effects of helminths on allergic diseases.

Maternal pre and perinatal experiences with their full-term, preterm and very preterm newborns.

Background: Mothers' reports about pregnancy, maternity and their experiences during the perinatal period have been associated with infants' later quality of attachment and development. Yet, there has been little research with mothers of very preterm newborns. This study aimed to explore mothers' experiences related to pregnancy, premature birth, relationship with the newborn, and future perspectives, and to compare them in the context of distinct infants' at-birth-risk conditions.

Prevalence of Performance-Enhancing Substance Use and Associated Factors among Portuguese Gym/Fitness Users.

Nowadays, doping is not confined to elite sport, it is also spread throughout gymnasia and fitness centers, and it is seen as a public health concern. Studies focusing on performance-enhancing substances (PES) use among gym users are few and mostly concern the practice of bodybuilding and the use of anabolic-androgenic steroids (AAS), without providing information about social indicators to further explore why this specific population use these substances. To investigate the extent of PES use and examine the way social indicators, exercise profile and gym modalities influence the use of these substances among a sample of gym users.

Determinants of the Intention to Use Performance-Enhancing Substances Among Portuguese Gym Users.

The purpose of this study is to examine the determinants of the intentions to use prohibited performance-enhancing substances (PES) and to test the Theory of Planned Behavior's usefulness in predicting self-reported PES use in both genders. A convenience sample of Portuguese gym users ( = 453) completed an anonymous web-based survey. Structural equation modeling, multigroup analysis, and -test with the Welch correction for heterokedastic variances were used.

A Photoelectrochemical Study of Bioinspired 2-Styryl-1-Benzopyrylium Cations on TiO Nanoparticle Layer for Application in Dye-Sensitized Solar Cells.

In the present work, five 2-styryl-1-benzopyrylium salts and their relative self-assembly processes towards TiO nanocrystalline layers were evaluated as photosensitizers in dye-sensitized solar cells (DSSCs). Integration of these 2-styryl-1-benzopyrylium salts with the semiconductor allow for the performance of highly specific functions suitable for smart applications in material science. Spectroscopic and photoelectrochemical measurements conducted on these five bio-inspired dyes, in solution and upon adsorption onto titanium dioxide films, allowed detailed discussion of the anchoring ability of the different donor groups decorating the 2-styryl-1-benzopyrylium core and have demonstrated their ability as photosensitizers.
