silicosis is considered to be among the occupational lung diseases and associated with sandblasting, mining, quarrying and tunneling. acute silicosis is usually progressive diseaseand despite treatment with corticosteroids it leads to cardio-respiratory failure and death. alveolar silicoproteinosis is one of it’s acute presentations due to exposure to silica dust and lungs filling with proteina...

Purpose: To determine prospectively the prevalence of testicular microlithiasis in symptomatic patients who were referred for scrotal ultrasound examination and to evaluate the possible association of testicular microlithiasis with testicular cancer. Material and method: 391 men who were referred to our institution between July 02 and May 05 for any type of symptoms from the testicles underwent...

Introduction: Testicular microlithiasis is an uncommon condition characterized by calcifi cations within the seminiferous tubules. The true prevalence in a normal population has not been defi ned. Methods: A review of the literature with emphasis on the connection between testicular microlithiasis and testicular malignancy was carried out. Results: Testicular microlithiasis is associated with d...

PURPOSE We assessed the prevalence of testicular microlithiasis by ultrasound in boys and young men with congenital or acquired undescended (ascending) testis. MATERIALS AND METHODS During followup for testicular growth patients with congenital or acquired undescended (ascending) testis were also screened by ultrasound for testicular microlithiasis, which was defined as echogenic foci without...

The systems of perception and action of the brain appear as important constraining factors in human evolution under current models of embodied cognition. In this view, the emergence of certain items in the archeological record is not necessarily subsequent to the emergence of a 'symbolic' mind, but instead to the appearance of the sensory-motor systems enabling that behavior. One of the product...

background: alveolar hypoxia induces monophasic pulmonary vasoconstriction in vivo, biphasic vasoconstriction in the isolated pulmonary artery, and controversial responses in the isolated perfused lung. pulmonary vascular responses to sustained alveolar hypoxia have not been addressed in the isolated perfused rat lung. in this study, we investigated the effect of sustained hypoxic ventilation o...

Aspiration of barium sulphate is known to sometimes accidentally occur during upper gastrointestinal contrast studies.

OBJECTIVE To prospectively determine the prevalence of testicular microlithiasis in symptomatic patients who were referred for scrotal ultrasound examination and to evaluate the possible association of testicular microlithiasis with testicular cancer and other conditions such as cryptorchidism or history of ascending testis. MATERIALS AND METHODS 391 men who were referred to our institutions ...

In this study the nature of chromosomal proteins, his tones and nonhistone in resident alveolar macrophages was investigated in comparison to peritoneal neutrophils and calf thymus proteins. Cells were obtained by lavaging the lung and after purity determination they were subjected to fractional extraction procedures. Proteins were then analysed on SDS polyacrylamide gels and densitometric...
