Comparison of Acute and Protracted Gamma Irradiation Effects During Perinatal Development in Beagle Dogs.

Ionizing radiation exposure during perinatal development can produce various biological effects on the developing offspring. These effects are dependent on a number of factors, including total dose, dose rate and the developmental processes occurring at the time of irradiation. The present study conducted an analysis of historical radiobiological archived data involving 60Co-gamma irradiation of beagle dogs at specific periods of prenatal or postnatal development.

Acute Impacts of Ionizing Radiation Exposure on the Gastrointestinal Tract and Gut Microbiome in Mice.

Radiation therapy for abdominopelvic malignancies often results in damage to the gastrointestinal tract (GIT) and permanent changes in bowel function. An overlooked component of the pathophysiology of radiation-induced bowel injury is the role of the gut microbiome. The goal of this research was to identify the impacts of acute radiation exposure on the GIT and gut microbiome.

Implications of COVID-19 On A Rapidly Growing Thymoma Case.

Introduction: Thymomas are a rare form of slow-growing malignancy that originate from thymic epithelial cells presenting as an anterior mediastinal mass. Although most are asymptomatic, they can have a variety of presentations, such as local thoracic symptoms, superior vena cava syndrome, or paraneoplastic syndromes. Local compressive thoracic symptoms include shortness of breath, chest pain, and cough.

Systemic and local responses of cytokines and tissue histology following intramammary lipopolysaccharide challenge in dairy cows.

During bovine mastitis, immune responses include the release of cytokines and the recruitment of leukocytes, resulting in profound structural and functional changes in the mammary gland. Our aims were to delineate systemic and local cytokine responses and to quantify histological changes in the mammary tissue of lactating cows after acute intramammary lipopolysaccharide (LPS) challenge. Ten multiparous dairy cows were paired to either treatment (TRT) or control (CON) groups.

Gender Issues in Physiotherapy in Quebec, Canada.

Purpose: This study examines gender differences in the physiotherapy (PT) profession in the province of Quebec regarding: (1) areas of practice; (2) roles associated with the advancement of the profession; (3) formal disciplinary complaints; and (4) interests and competency perceptions of PT students.

Methods: We collected data from the Canadian Institute of Health Information, the Quebec Professional Order of Physiotherapy, Quebec university public Internet sites, and PT associations. We also surveyed PT students at the Université de Montréal.
