Sparing of the Heart Facilitates Recovery From Cardiopulmonary Side Effects After Thoracic Irradiation.

Purpose: When irradiating thoracic tumors, dose to the heart or lung has been associated with survival. We previously showed in a rat model that in addition to known side effects such as pericarditis, pneumonitis and fibrosis, heart and/or lung irradiation also impaired diastolic function and increased pulmonary artery pressure. Simultaneous irradiation of both organs strongly intensified these effects.

sp. nov., a novel bacterial species associated with the gills of the fiddler crab (Brachyura, Ocypodidae) from Red Sea mangroves.

Two bacteria, UG2_1 and UG2_2, were isolated from the gill tissues of the mangrove fiddler crab collected on the east coast of the Red Sea (Thuwal, Saudi Arabia). The cells are Gram-negative, rod-shaped, orange-pigmented, motile by gliding with no flagella, strictly aerobic, and grow at 20-37 °C (optimum, 28-35 °C), at pH 5.0-9.

Retrospective cohort study on the bilateral occurrence of invasive lobular breast cancer.

Objective: Invasive lobular carcinoma (ILC) is the second most common histological subtype of invasive breast cancer, following the no special type (NST) invasive carcinoma. It has historically been assumed that ILC occurs bilaterally in 20-29 % of cases, which has influenced the inclusion of MRI in the standard workup of ILC according to European guidelines. However, challenging this long-held belief regarding the bilateral occurrence of ILC opens up the possibility of revising the guidelines and using MRI only for more specific indications.

Literature review on the bilateral occurrence of invasive lobular breast cancer.

Historically, it has been believed that invasive lobular carcinomas (ILC) occur more frequently bilaterally compared to other invasive subtypes, with estimates ranging between 20% and 29%. This study aims to determine if this historical perspective still holds true. A comprehensive literature review was conducted to examine the bilateral occurrence of lobular carcinoma using various imaging methods.

Radiation-induced DNA double-strand breaks in cortisol exposed fibroblasts as quantified with the novel foci-integrated damage complexity score (FIDCS).

Without the protective shielding of Earth's atmosphere, astronauts face higher doses of ionizing radiation in space, causing serious health concerns. Highly charged and high energy (HZE) particles are particularly effective in causing complex and difficult-to-repair DNA double-strand breaks compared to low linear energy transfer. Additionally, chronic cortisol exposure during spaceflight raises further concerns, although its specific impact on DNA damage and repair remains unknown.
