Coronavirus disease 2019 (COVID-19) still causes death in elderly and immunocompromised individuals, for whom the sustainability of the vaccine response may be limited. Antiviral treatments, such as remdesivir or molnupiravir, have demonstrated limited clinical efficacy. Nirmatrelvir, an acute respiratory syndrome coronavirus 2 (SARS-CoV-2) major protease inhibitor, is clinically effective but has been associated with viral rebound and antiviral resistance.

The Amazon rainforest is renowned for its biodiversity and as a reservoir of edible and medicinal plants. The phytochemicals in murici and taperebá fruits serve as natural antioxidants, contributing to cultural preservation, ecosystem protection, and economic opportunities. However, limited scientific research on their composition and health benefits hinders their recognition as functional foods.

Transthyretin (TTR) is a vertebrate-exclusive transport protein that plays a key role in binding and distributing thyroid hormones. However, its evolutionary origin lies in the duplication of the gene that encoding the enzyme 5-hydroxyisourate hydrolase (HIUase), which is involved in uric acid metabolism. Unlike TTR, HIUase is ubiquitous in both prokaryotes and eukaryotes, with the exception of hominids.

Background And Aim: Diabetes has been shown in last decades to be associated with a significantly higher mortality among patients with ST-segment elevation myocardial infarction (STEMI) treated with primary PCI (PPCI). Therefore, the aim of current study was to evaluate the impact of diabetes on times delays, reperfusion and mortality in a contemporary STEMI population undergoing PPCI, including treatment during the COVID pandemic.

Methods And Results: The ISACS-STEMI COVID-19 is a large-scale retrospective multicenter registry involving PPCI centers from Europe, Latin America, South-East Asia and North-Africa, including patients treated from 1st of March until June 30, 2019 and 2020.

Autosomal dominant polycystic kidney disease (ADPKD) is a multisystemic heterogeneous disease characterized by the presence of cysts in several organs leading to progressive dysfunction. The cardiovascular manifestations of ADPKD include hypertension, left ventricular hypertrophy, and valvular heart disease, predominantly mitral valve abnormalities. We present the case of a 30-year-old male with a past medical history of ADPKD who was admitted to the emergency department due to sudden chest pain and signs of congestive heart failure for weeks.

Article Synopsis
  • Atopic dermatitis (AD) and mycosis fungoides (MF) can be difficult to distinguish because they exhibit similar symptoms like inflamed and itchy skin lesions.
  • A case study of a 19-year-old male with a past AD history highlights the diagnostic confusion when he developed atypical eczema-like lesions that required advanced testing to confirm MF after initial misdiagnosis.
  • The case underscores the importance of accurate and early diagnosis to differentiate between AD and MF, as MF requires specific treatments, and it encourages further research into shared mechanisms for improved patient care.

The Strategic Plan for Cardiovascular Health in Portugal is an initiative of the Portuguese Society of Cardiology, aligned with efforts by the European Society of Cardiology and the World Heart Federation to develop national plans, at a local level within the cultural and socio-economic contexts, focused on cardiovascular health. The overarching goal is to promote and ensure the continuous and sustained improvement of cardiovascular health in the Portuguese population. The methodology identified key challenges and opportunities for the medium term, highlighted priority areas for intervention, and proposed strategic lines of action.

Article Synopsis
  • Trema micranthum, a plant from the Cannabaceae family, shows potential as a new source of cannabinoids like CBD, amid the regulatory issues surrounding Cannabis sativa due to THC content.
  • This study used advanced UHPLC-HRMS/MS techniques to analyze different parts of the plant—fruits, leaves, inflorescences, and stems—for the presence of CBD, THC, and their acidic precursors (THCA A and CBDA).
  • The results revealed significant levels of cannabinoids, especially in the leaves (4.43 µg/g CBD, 1.05 µg/g THC), indicating that Trema micranthum could serve as a viable alternative source for cannabinoid research and production.

Background: Evolutionary divergence and genetic variation are often linked to differences in microbial community structure and diversity. While environmental factors and diet heavily influence gut microbial communities, host species contributions are harder to quantify. Closely related species living in sympatry provide a unique opportunity to investigate species differences without the confounding effects of habitat and dietary variation.

Zika virus (ZIKV) infection causes significant human disease that, with no approved treatment or vaccine, constitutes a major public health concern. Its life cycle entirely relies on the cytoplasmic fate of the viral RNA genome (vRNA) through a fine-tuned equilibrium between vRNA translation, replication, and packaging into new virions, all within virus-induced replication organelles (vROs). In this study, with an RNA interference (RNAi) mini-screening and subsequent functional characterization, we have identified insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) as a new host dependency factor that regulates vRNA synthesis.

Purpose: The Achilles tendon is a common injury site, but anatomical risk factors for injury are relatively unexplored in the literature. This study aimed to evaluate whether changes in free tendon length would influence the results of a simulated rupture of the Achilles tendon.

Methods: Using a previously validated 3D finite element model of the free and aponeurotic Achilles tendon as a basis, two additional finite element models with 25% decreased and increased free tendon lengths were created.

Background: Synthetic biology involves combining different DNA fragments, each containing functional biological parts, to address specific problems. Fundamental gene-function research often requires cloning and propagating DNA fragments, such as those from the iGEM Parts Registry or Addgene, typically distributed as circular plasmids.Addgene's repository alone offers around 150,000 plasmids.
