Methods: Retrospective cohort study by analyzing medical records of singleton pregnancies from two consecutive years (2018 and 2019). FGR was defined according to Delphi Consensus.

Apomixis beyond trees in the Brazilian savanna: new insights from the orchid .

n the Neotropics, the focus of apomictic studies predominantly centres on trees within the Brazilian savanna, characterized, mostly as sporophytic and facultative, associated with polyploidy and polyembryony. To enhance our understanding of the mechanisms governing apomixis and sexual reproduction in tropical herbaceous plants, we clarify the relationship between apomixis, chromosome counts, and polyembryony in the epiphytic orchid , which forms a polyploid complex within rocky outcrops in both the Brazilian savanna and the Atlantic forest. To define embryo origins and describe megasporogenesis and megagametogenesis, we performed manual self-pollinations in first-day flowers of cultivated plants, considering all three cytotypes (2, 3, 4) of this species.

The RNA binding proteins LARP4A and LARP4B promote sarcoma and carcinoma growth and metastasis.

RNA-binding proteins (RBPs) are emerging as important regulators of cancer pathogenesis. We reveal that the RBPs LARP4A and LARP4B are differentially overexpressed in osteosarcoma and osteosarcoma lung metastases, as well as in prostate cancer. Depletion of LARP4A and LARP4B reduced tumor growth and metastatic spread in xenografts, as well as inhibiting cell proliferation, motility, and migration.

Long-term effect of firing protocols on surface roughness and flexural strength of lithium disilicate glass-ceramic.

This study evaluated the effect of different firing protocols on the surface roughness and flexural strength of CAD/CAM lithium disilicate glass-ceramic (LD) after aging methods. Forty-two LD bars of 16 x 4 x 2 mm (IPS e-max CAD, Ivoclar) were randomly separated into two groups according to firing protocols: Single firing-Staining, glazing, and crystallization in a single step; Multiple firings-Crystallization+First staining+Firing+Second staining+Firing+Glazing+Firing. After protocols, initial surface roughness readings were taken (Surfcorder SE1700, Kosakalab).

Examination of Raw Samples and Ethanol Extracts of Gerês Propolis Collected in Different Years.

Propolis, a natural resin created by bees, has garnered significant attention from both the scientific community and industry due to an impressive range of bioactivities. Nonetheless, the intrinsic variability in its chemical composition and bioactive profiles has been hindering propolis' full potential use. We previously showed that ethanol extracts (EEs) of a Portuguese propolis sample (Gerês) collected over four consecutive years displayed similar chemical and biological profiles, a constancy never documented before.

Ultra-light-weight microwave X-band EMI shielding or RAM material made from sustainable pyrolysed cork templates.

We valorised waste cork and recycled wine stoppers to make pyrolysed/carbonised solid cork, for use as economic and sustainable microwave (MW) absorbers at the microwave X-band (8-12 GHz), without binder or additives. Although cork is already a very lightweight material (0.

THE ROLE OF BOWEL DIARIES IN A "REAL-LIFE" SETTING.

Background: Despite the potential advantages of patients' self-recordings of bowel habits in lower digestive disorders, few studies evaluate the relevance of clinical information obtained through bowel diaries in clinical practice.

Objective: The main objective of this study was to evaluate the role of bowel diaries as an auxiliary diagnostic tool in lower gastrointestinal disorders consultations.

Methods: In this cross-sectional study, at the end of their gastroenterology consultation, patients were questioned about their bowel habits and gastrointestinal symptoms.

Phenolic Compounds Contribution to Portuguese Propolis Anti-Melanoma Activity.

Melanoma is the deadliest type of skin cancer, with about 61,000 deaths annually worldwide. Late diagnosis increases mortality rates due to melanoma's capacity to metastasise rapidly and patients' resistance to the available conventional therapies. Consequently, the interest in natural products as a strategy for drug discovery has been emerging.

Spatially resolved transcriptomics reveals pro-inflammatory fibroblast involved in lymphocyte recruitment through CXCL8 and CXCL10.

The interplay among different cells in a tissue is essential for maintaining homeostasis. Although disease states have been traditionally attributed to individual cell types, increasing evidence and new therapeutic options have demonstrated the primary role of multicellular functions to understand health and disease, opening new avenues to understand pathogenesis and develop new treatment strategies. We recently described the cellular composition and dynamics of the human oral mucosa; however, the spatial arrangement of cells is needed to better understand a morphologically complex tissue.

Expression of periodontitis susceptibility genes in human gingiva using single-cell RNA sequencing.

Objective: Single-cell transcriptomics was used to determine the possible cell-type specificity of periodontitis susceptibility genes.

Background: The last decade has witnessed remarkable advances in the field of human genomics. Despite many advances, the genetic factors associated with or contributing to the periodontitis pathogenesis have only been identified to a limited extent and are often poorly validated.

Eosinophilic Gastroenteritis: Still a Diagnostic Challenge.

Introduction: Eosinophilic gastroenteritis (EoG) is a rare condition with a yet poorly understood pathophysiology.

Case Presentation: We report on a case of a 36-year-old woman with a history of atopy presenting with nausea, abdominal discomfort, weight loss, and ascites. Laboratorial analysis revealed peripheral eosinophilia and a slight elevation of inflammatory markers.

Oral stem cells, decoding and mapping the resident cells populations.

The teeth and their supporting tissues provide an easily accessible source of oral stem cells. These different stem cell populations have been extensively studied for their properties, such as high plasticity and clonogenicity, expressing stem cell markers and potency for multilineage differentiation in vitro. Such cells with stem cell properties have been derived and characterised from the dental pulp tissue, the apical papilla region of roots in development, as well as the supporting tissue of periodontal ligament that anchors the tooth within the alveolar socket and the soft gingival tissue.

Constipation: Prevalence in the Portuguese community using Rome IV-Associated factors, toilet behaviours and healthcare seeking.

Background: Chronic constipation (CC) is a major public health condition and CC management remains challenging.

Objective: We aimed to evaluate the CC (and subtypes) prevalence in a Southern Europe Mediterranean country using Rome IV criteria, and to assess related factors, toilet and healthcare seeking behaviours.

Methods: Cross-sectional epidemiological survey, conducted in general community and representing the Portuguese population according to sex and age.

Unravelling the Affinity of Alkali-Activated Fly Ash Cubic Foams towards Heavy Metals Sorption.

In this work, alkali-activated fly ash-derived foams were produced at room temperature by direct foaming using aluminum powder. The 1 cm foams (cubes) were then evaluated as adsorbents to extract heavy metals from aqueous solutions. The foams' selectivity towards lead, cadmium, zinc, and copper ions was evaluated in single, binary, and multicomponent ionic solutions.

Ultrafiltration for acute heart failure.

Background: Pharmacotherapies such as loop diuretics are the cornerstone treatment for acute heart failure (AHF), but resistance and poor response can occur. Ultrafiltration (UF) is an alternative therapy to reduce congestion, however its benefits, efficacy and safety are unclear.

Objectives: To assess the effects of UF compared to diuretic therapy on clinical outcomes such as mortality and rehospitalisation rates.

Cecal MALT lymphoma: a challenging diagnosis.

A 76-year-old female with a medical history of diabetes, arterial hypertension and dyslipidemia sought medical assistance due to left flank abdominal pain, fatigue and anorexia over the previous month. Laboratory analyses were normal and the computed tomography (CT) scan showed colonic diverticulosis and mesenteric panniculitis.

Validation of the IBD-Disk in a Portuguese cohort.

Objective: The aim of this study was to validate the IBD-Disk in a Portuguese cohort according to the COnsensus-based Standards for the selection of the health Measurement INstruments (COSMIN) recommendations.

Prediction of Lung Maturity in Fetuses with Growth Restriction through Quantitative Ultrasound Analysis.

The present study aimed to evaluate the performance of QuantusFLM software, which performs quantitative analysis of lung tissue texture through ultrasound images, in predicting lung maturity in fetal growth restriction (FGR). We included patients with singleton gestations between 34 and 38 6/7 wk and divided them into two groups: FGR and control (appropriate for gestational age [AGA]). The images were captured by ultrasound according to a specific protocol up to 48 h before delivery and analyzed with QuantusFLM software.

Waste-Based One-Part Alkali Activated Materials.

Ordinary Portland Cement is the most widely used binder in the construction sector; however, a very high carbon footprint is associated with its production process. Consequently, more sustainable alternative construction materials are being investigated, namely, one-part alkali activated materials (AAMs). In this work, waste-based one-part AAMs binders were developed using only a blast furnace slag, as the solid precursor, and sodium metasilicate, as the solid activator.

Physiopathology of late-onset fetal growth restriction.

Fetal growth restriction (FGR) is defined as the inability of the fetus to reach its potential for genetic determination. FGR can have several causes, including genetic syndromes, chromosomal diseases, and infections; however, a vast majority of cases are probably attributed to impaired uterine and placental circulation. The relationships between abnormal placental development and FGR are complex, and studies are generally few, presenting confounding factors.
