The fungus Aspergillus tamarii metabolizes progesterone to testololactone in high yield through a sequential four step enzymatic pathway which, has demonstrated flexibility in handling a range of steroidal probes. These substrates have revealed that subtle changes in the molecular structure of the steroid lead to significant changes in route of metabolism.(More)
Aspergillus tamarii contains an endogenous lactonization pathway which can transform progesterone to testololactone in high yield through a sequential four step enzymatic pathway. In this pathway testosterone is formed which primarily undergoes oxidation of the C-17beta-alcohol to a C-17 ketone but, can also enter a minor hydroxylation pathway where(More)
Four isomers of 5α-androstan-3,17-diol have been transformed by the filamentous fungus Aspergillus tamarii, an organism which has the ability to convert progesterone to testololactone in high yield through an endogenous four step enzymatic pathway. The only diol handled within the lactonization pathway was 5α-androstan-3α,17β-diol which, uniquely underwent(More)
In agreement with the findings of others, heart carnitine levels of male, weanling Sprague-Dawley rats fed nutritionally adequate liquid diets with 35% of calories as ethanol for 3 weeks were not different from control or pair-fed rats (Experiment 1). When ethanol was given as 30% of energy in combination with a diet deficient in methionine and choline, and(More)
Bazex Syndrome (acrokeratosis paraneoplastica) is characterized by a psoriasiform skin eruption that favors acral sites and has been associated with underlying malignancy in all reported cases. Squamous cell carcinoma of the upper third of the respiratory system and upper third of the gastrointestinal tract and squamous cell carcinoma of unknown primary(More)
Dysphagia is not infrequent in patients with connective tissue diseases such as scleroderma, polymyositis or systemic lupus erythematosus (SLE). It is usually the result of gastro-oesophageal reflux but dysmotility can equally be responsible. A case of dysphagia is described in a patient with SLE, who had developed a rare variety of bullous mucous disease(More)
