Recently, it has been proven that manganese from inhaled particles of manganese compounds can accumulate in the internal organs of laboratory animals. Nevertheless, there were only a few researches dealing with changes in body morphology induced by inhalation of these particles, even though results of some studies indicate existence of such changes. The aim of our research was to assess the eff...

background: several regulatory proteins are involved in salmonella invasion. the key regulator of spi-1 (salmonella pathogenicity island 1 ) is hila, a transcriptional activator encoded on spi-1 that regulates the expression of the spi-1 secretion system. objectives: importance of hila mutation on s. enteritidis colonization and shedding in layer hens was evaluated in a long-term experiment. me...

Scleroderma is an autoimmune disease affecting the skin and sometimes internal organs of body. There are two types scleroderma, localized scleroderma or systemic. The most common type in children it scleroderma.

A novel X-ray technique shows that the internal organs of crawling caterpillars slide past the body walls like pistons in a new kind of legged locomotion.

Systemic sclerosis, or scleroderma, is a complex medical disorder characterized by limited or diffuse skin thickening with frequent involvement of internal organs such as lungs, gastrointestinal tract, or kidneys. Docetaxel is a chemotherapeutic agent which has been associated with cutaneous side effects. An uncommon cutaneous side effect of docetaxel is scleroderma-like skin changes that exten...

Malignant Mesothelioma (MM) is a rare form of cancer that affects the thin cell wall lining of the body's internal organs and structures.[...].

The internal organs of rats and rabbits were clearly imaged noninvasively using a deeply penetrating reflection-mode photoacoustic imaging system. This imaging system had previously been found to provide an imaging depth limit of approximately 38 mm. In the thoracic cavity, major blood vessels connecting to the heart were imaged, and the right atrium was imaged as deeply as approximately 8 mm. ...

Host-parasite interactions of Pomphorhynchus laevis (Müller, 1776) in naturally infected amphipod, Echinogammarus stammeri (Karaman), from the Brenta River (northern Italy) are described. A fully developed acanthocephalan larva occupies a large portion of an amphipod's haemocoelic space; thus, the parasite frequently induces displacement of host digestive tract and other internal organs. Howeve...

Systemic sclerosis (SSc) is a clinically heterogeneous, systemic disorder affecting connective tissue of skin, internal organs, and walls of blood vessels. It is characterized by alterations of the microvasculature in the form of hypoxia, digital ulcers, and pulmonary arterial hypertension; disturbances of the immune system, including dysbalance of cytokine expression, autoantibodies (Auto-ab),...

nowadays, bivalves are used in monitoring levels of heavy metals in aquatic environments. the aim of this study was to investigate bioaccumulation of heavy metals zinc (zn) and chromium (cr) in the internal organs of anodonta cygnea. for this purpose, bivalve specimens were collected from semeskandeh region, sari, and then in laboratory, were exposed to 125 µg l-1 concentrations of each metal f...
