Laboratory- and Pilot-Scale Cultivation of to Produce Valuable Metabolic Compounds.

Marine microalgae are considered an important feedstock of multiple valuable metabolic compounds of high biotechnological potential. In this work, the marine microalga was cultivated in different scaled photobioreactors (PBRs). Initially, experiments were performed using two different growth substrates (a modified F/2 and the commercial fertilizer Nutri-Leaf (30% TN-10% P-10% K)) to identify the most efficient and low-cost growth medium.

Virtual endoscopy in the diagnosis of an adult double tracheal bronchi case.

We report a case of ipsilateral double tracheal bronchi supplying a tracheal lobe in a 42-year-old man, who presented with a 10-year history of recurrent respiratory infections. Diagnosis was established by chest computed tomography (CCT), virtual endoscopy and bronchoscopy. Both bronchi were surgically resected along with the right upper lobe of the lung and the associated tracheal lobe.

Blood use in lung resection for carcinoma: perioperative elective anaemia does not compromise the early outcome.

Objective: Blood transfusion may adversely affect the prognosis following surgery for non-small cell lung carcinoma (NSCLC). Conventionally by most thoracic surgeons, a perioperative haemoglobin (Hb) less than 10 g/dl has been considered a transfusion trigger. In this prospective trial we have (a) evaluated the overall blood transfusion requirements and factors associated with an increased need for transfusion and (b) in a subsequent subset of patients, tested the hypothesis that elective anaemia after major lung resection may be safely tolerated in the early postoperative period.

Bronchial carcinoid of an accessory tracheal bronchus.

We present a rare case of bronchial carcinoid tumor arising in an accessory right tracheal bronchus and involving the associated tracheal lobe in a 48-year-old man, who presented with a history of recurrent respiratory infections and recent onset of hemoptysis. Diagnosis was established on preoperative bronchoscopy and biopsy. The tumor was completely removed by right upper lobectomy with the tracheal bronchus resected flush to its origin from the right lower tracheal wall.
