Efficient electropulse transformation of intact Candida maltosa cells by different homologous vector plasmids.

Conditions for efficient and quick transformation by electroporation were developed in Candida maltosa. To investigate the efficiency of transformation with integrative as well as with autonomously replicating plasmids, a series of vectors was constructed for homologous transformation of this species. Transformants were obtained with different plasmids as covalently closed circular molecules and as linearized DNA. The influence of recipient strain and plasmid type as well as of cell number and parameters of the supplied electrical pulse on the transformation efficiency have been investigated. A maximum of 7000 transformants per 100 ng of plasmid DNA was reached. The efficiency of transformation was compared with that of the LiCl method.

Correlation of biochemical blocks and genetic lesions in leucine auxotrophic strains of the imperfect yeast Candida maltosa.

The four enzymatic steps in the conversion of alpha-ketoisovaleriate to leucine were examined in the wild type and in 13 leucine auxotrophic strains of Candida maltosa. The genetic lesions in the auxotrophs, involve at least five different loci and are correlated with three enzymatic steps. This was confirmed by gene cloning, protoplast fusion, and enzyme assays. The pathway for leucine biosynthesis in C. maltosa shows general similarity to that of other lower eukaryotes but there are individual differences in the numbers of genes responsible for single enzymatic steps. A disomic state of the chromosomes carrying genes coding for alpha-isopropylmalate synthase and beta-isopropyl-malate dehydrogenase was elucidated.

[The concept of integrated internal medicine-psychosomatic patient management--experiences and results with its application in a general hospital].

Psychosomatic therapy has been realized by integration into general ward's therapeutic program in a general hospital. Within 3 1/2 years of development the medical staff has been qualified to perform basic elements of psychosomatic therapy, whilst the structure of the medical department has been changed in different aspects. During a period of 28 days the real extend of psychosomatic therapy now has been evaluated by questionnaire: 438 psychosomatic and psychosocial interventions were documented in this time, concerning 149 patients (= 53% of all patients treated in the department). Causes, trigger mechanic, settings, frequency, median duration, and different kinds of all these interventions are described. According to the clientèle of our medical department, with a lot of elderly and multi-handicapped persons, the main topics of interventions concerned--besides of specific psychosomatic treatment--addiction and problems of alcoholism, coping strategies and compliance, as well as further support of handicapped singles after discharge.
