Incidence and survival of European adolescents and young adults diagnosed with sarcomas: EUROCARE-6 results.

Background: Epidemiological data for sarcoma in adolescents and young adults (AYAs) and across age groups are limited. We aim to: 1) update sarcoma incidence, survival, and changes over time in European AYAs; 2) provide an updated comparison of sarcoma survival in AYAs versus children and mature adults.

Methods: We calculated crude incidence rates (IR) per 100,000 European population per year from 2006 to 2013.

Biomonitoring potential of trace metal accumulation and bioavailability in coral skeletons and reef sediments of Persian Gulf: A comparative study.

Nayband Marine National Park in the northern Persian Gulf is an important ecological areas, significantly impacted by industrial activites that poses risk of trace metal pollution to living organisms. In this study, we investigated the bioaccumulation of trace metals in scleractinian corals using annual growth bands and biota-sediment accumulation factor to assess their potential as biomonitoring organisms. Furthermore, to assess the sediment quality, sediment pollution indices and international guidelines was employed.

Evaluating the Cavitary Lung Lesions on CT Scan of COVID-19 Patients: A Retrospective Study.

Background: It has been shown that cavitary lesions on CT scans of patients with COVID-19 may be related to their clinical symptoms and mortality rate.

Materials And Methods: The study population included patients diagnosed with COVID-19 based on RT-PCR results from throat samples or typical clinical and chest CT scan findings who were hospitalized at Sina Hospital in Tehran in 2020 and underwent chest CT scans. Chest CT scans were examined for the severity of pulmonary opacities and the presence, number, size, wall thickness, and distribution of cavitary lung lesions.

Enhanced superhydrophobic robustness of black silicon employing nanojungle structures.

Superhydrophobic surfaces are essential in various industries such as textiles, aviation, electronics and biomedical devices due to their exceptional water-repellent properties. Black silicon (b-Si) would be an ideal candidate for some applications due to its nanoscale topography made with a convenient lithography-free step and complementary metal-oxide-semiconductor (CMOS) compatible fabrication process. However, its use is hindered by serious issues with mechanical robustness.

Synergistic Interaction of Chloroquine with Semipolar Extract Against : Histopathological and Immunological Studies in a Mouse Model.

Background: Malaria parasites have gradually developed resistance to commonly used antimalarial drugs. For decades, chloroquine was the most widely used drug to eradicate malaria. However, with the spread of chloroquine resistance, many countries have adopted combination therapies that utilize two drugs acting synergistically instead of monotherapy.
