Department of Marine Biology, Leon H. Charney School of Marine Sciences, University of Haifa, 3498838, Israel; Israel Sea Turtle Rescue Center, Israel National Nature and Parks Authority, Gan Leumi Beit Yannay, Kfar Vitkin, Israel.

The Eastern Mediterranean Sea (EMS) exhibits high temperature and salinity, low levels of biologic production and is considered oligotrophic. Nonetheless, it is also a hotspot of biodiversity, with several important endangered flagship species, including several species of sea turtles. These turtles serve as bioindicators for the health of their ecologic systems, due to changes in diet, habitat and migration patterns that characterize different stages in their lives.

INC Hospital, Department of Interventional Cardiology, Universidade Federal do Paraná, Faculdades Pequeno Príncipe, Hospital Santa Casa de Misericórdia de Curitiba, Rua Jeremias Maciel Perretto, 300, Curitiba, Paraná, 81210-310, Brazil. Electronic address:

Article Synopsis
  • Direct Oral Anticoagulants (DOACs) are commonly used for treating non-valvular atrial fibrillation (NVAF), but Percutaneous Left Atrial Appendage Occlusion (LAAO) is a new treatment method with uncertain safety and effectiveness compared to DOACs.
  • A systematic review of ten studies involving over 18,500 patients found that LAAO is linked to lower all-cause and cardiovascular mortality rates, as well as a reduction in the composite outcomes of death, bleeding, and thromboembolic events.
  • While LAAO showed trends toward reduced stroke or TIA events and lower bleeding rates compared to DOACs, no significant differences in thromboembolic events were observed.

  • The study investigated two methods—high-pressure homogenization (HPH) at 100 and 1200 bar, and enzymatic hydrolysis (EH)—to extract biostimulants from Tetradesmus obliquus, a microalga grown in piggery wastewater.
  • The extracts were tested on garden cress, mung beans, and cucumbers to assess their growth-promoting effects, with untreated microalgal cultures showing the best germination rates and cytokinin-like activity.
  • High-pressure homogenization at 1200 bar and enzymatic hydrolysis yielded significant increases in auxin-like activity for mung beans and cucumbers, suggesting that the extracted biomass could be beneficial for sustainable agricultural applications.

The nanostructured assembly of different two-dimensional (2D) materials in specific organization is crucial for developing materials with synergistic properties. In this study, we present a general methodology to prepare thin, transparent and self-assembled films of 2D/2D composites based on molybdenum sulfide (MoS)/graphene oxide (GO) or MoS/reduced graphene oxide (rGO), through the liquid/liquid interfacial route. Different nanoarchitectures are obtained by changing simple experimental parameters during the thin film preparation steps.

As a pre-fermentative practice, cold may facilitate the extraction of grape compounds, resulting in differentiated wines. To explore the potential of these practices, extensive research has been conducted on scientific publications since 2004. There are four main ways to apply cold in pre-fermentative practices: ice wine production, berry freezing, cold maceration of grape must, and cryoconcentration of grape must.

Article Synopsis
  • There’s a debate about how long patients with heart problems should take two types of medicine together, called dual antiplatelet therapy (DAPT).
  • Researchers wanted to see how effective and safe different lengths of DAPT are for patients who have serious heart issues and receive a special procedure to help their hearts.
  • They found that taking DAPT for just 1 month followed by another medicine might reduce serious bleeding, but didn't change the number of heart problems compared to taking DAPT for 12 months.

The disposable soma theory (DST) posits that organisms age and die because of a direct trade-off in resource allocation between reproduction and somatic maintenance. DST predicts that investments in reproduction accentuate somatic damage which increase senescence and shortens lifespan. Here, we directly tested DST predictions in breeding and nonbreeding female C57BL/6J mice.
