A 23-year-old woman, who had suffered recurrent acute bronchitis, dyspnoea, and stridor, was found to have a tracheal stenosis and complete left main bronchus obstruction. Biopsy of the tumour showed an adenoid cystic carcinoma. After pneumonectomy the trachea was closed through tumour tissue. Two weeks later a right thoracotomy showed that a tumour had invaded the trachea from the carina up to...

Endobronchial metastasis secondary to osteosarcoma is distinctly rare. 2 We report a young man with metastatic osteosarcoma who presented with position-dependent dyspnoea. A CT scan of the chest showed a soft tissue mass that originated from the left lung, causing significant volume loss of the left lung, extended through the left main bronchus and projected to the trachea (fig 1A,B). Bronchosc...

Uniaxial compressive strength (UCS) and elastic properties of rocks play a major and vital role for the design of any engineering structure. The specimen diameter size is one of the main factors that influencing on UCS, elasticity modulus and Poisson’s ratio (E and υ). Here, an attempt has been made to investigate the effect of specimen diameter size on UCS, E and υ. Moreover, we studied the co...

The aim of investigation was to determine the effects of aspect (north and south) on some morphological [plant height (cm), number of stems per plant, main stem diameter (mm), number of leaves per main stem, petiole length (cm), leaflet length (cm), leaflet width (cm), leaf: stem ratio] and chemical [crude protein (%), crude cellulose (%), calcium (%), phosphorus (%), potassium (%) and magnesiu...

Aspiration of tracheobronchial foreign bodies commonly affects young children, is potentially life threatening and requires early intervention for extraction. Access to facilities and skill manpower for bronchoscopic extraction is however limited in Nigeria. The aim of this study is to describe the experience in our institution with bronchoscopic removal of tracheobronchial foreign bodies and h...

A 59-year-old man was admitted with hemoptysis for 1 month. Chest X-ray and CT scan showed a foreign body (teeth) at right main bronchus and left central mass (Fig. 1a and b), upon which we suspected lung carcinoma. Bridge prosthesis with three teeth at the orifice of the right main bronchus was removed (Fig. 2) and biopsy taken from the tumoral lesion at left main bronchus revealed epidermoid ...

Fe-Cr-Al alloy nanopowders were successfully prepared by electrical wire explosion method in ethyl alcohol media. The formation of FeCr-Al alloy nanopowder was monitored by X-ray diffraction. The alloy powders have spherical shape and nanometer size. The alloy powders prepared by the electrical wire explosion method have main crystal structures of bcc Fe-Cr alloy. The geometric mean diameter an...
