A polyhydroxyalkanoates bioprocess improvement case study based on four fed-batch feeding strategies.

The modelling and optimization of a process for the production of the medium chain length polyhydroxyalkanoate (mcl-PHA) by the bacterium Pseudomonas putida KT2440 when fed a synthetic fatty acid mixture (SFAM) was investigated. Four novel feeding strategies were developed and tested using a constructed model and the optimum one implemented in further experiments. This strategy yielded a cell dry weight of 70.

Anxiety and depression in patients with advanced ovarian cancer: a prospective study.

Introduction: Survival of ovarian cancer patients is still unsatisfactory despite the introduction of new diagnostic and therapeutic methods. Women with advanced ovarian cancer with long-term survival are at persistent risk of anxiety and reactive depression due to poor prognosis and risk of burdensome symptoms. The aim of the study was to assess changes in anxiety and depression during multimodality ovarian cancer treatment and to identify correlates of anxiety and depression.

Chlormequat poisoning is not without risk: Examination of seven fatal cases.

Chlormequat chloride is a plant growth regulator. Chlormequat poisoning clinically resembles anticholinesterase insecticide poisoning. The cholinergic symptoms result from direct action on nicotinic and muscarinic receptors and not from inhibition of the cholinesterase activity.

Immediate passive motion versus immobilization after endoscopic supraspinatus tendon repair: a prospective randomized study.

Introduction: Rehabilitation programs after rotator cuff repair should allow recovery of shoulder function without preventing tendon healing. The aim of this randomized prospective study was to compare the clinical results after two types of postoperative management: immediate passive motion versus immobilization.

Patients And Methods: We followed 100 patients, mean age 55 years old, who underwent arthroscopic repair of a non-retracted supraspinatus tear.

Doppler evaluation of external iliac vein hemodynamic changes caused by lymphocele after lymphadenectomy for cervical cancer.

Purpose: To use Doppler sonography to assess the hemodynamic changes in the external iliac vein (EIV) compressed by a pelvic lymphocele after pelvic lymphadenectomy in patients with cervical cancer.

Materials And Methods: Postoperative gray-scale and Doppler sonographic examinations were performed in 71 women after pelvic lymphadenectomy. Twenty healthy women served as controls.
