OBJECTIVE Obsessive-compulsive disorder (OCD) symptoms are common in people who are ill with bulimia nervosa. However, little is known about whether OCD symptoms persist after long-term recovery from bulimia. METHOD Thirty-one female patients with bulimia nervosa, 29 women who had been recovered from bulimia for more than 1 year, and 19 healthy female comparison subjects completed the Yale-Br...

A biological exposure method was developed that allows wood samples to be progressively removed for monitoring colonization and decay by basidiomycete fungi. Monitoring involves strength tests, determination of weight loss, and chemical analysis. To optimize the procedure, several variations of the method were tested using two species of brown-rot fungi (Gloeophyllum trabeum and Oligoporus plac...

A collagenase-dispersion method involving Percoll gradient separation is described for the production of adipocytes from foetal rat brown adipose tissue. The cells produced are hormone-sensitive as judged by cAMP accumulation and lipolysis.

J.-L. Loday has used w-cubes of fibrations, where n is a non-negative integer, in his study of spaces with finitely many non-trivial homotopy groups [4]. His main result is the construction of an algebraic category equivalent to the weak homotopy category of path-connected spaces Z with TI^Z = 0 for / > w+1 [4, 1.7]. One step in the proof [4, 3.5] requires the construction of certain «-cubes of...

This study presents a method of estimating the degree to which people change their racial/ethnic identity from one census enumeration to another. The technique is applied to the classification of skin colour in Brazil (white, black, brown, yellow). For the period 1950-80, the findings show a deficit of 38 per cent in the black category and a gain of 34 per cent in the brown category, suggesting...

BACKGROUND Biliary tract stones account for the majority of cases with acute pancreatitis, and include black and brown pigment stones. The aim of the study was to compare the presentation and outcome in cholecystectomized patients with acute biliary pancreatits caused by black and brown pigment stones. METHOD Data from patients with prior cholecystectomy and acute biliary pancreatitis were co...

Incipient decay of wood by brown rot fungi causes measurable strength losses in wood before measurable weight loss occurs. Previous studies have shown that the high levels of strength loss that occur during incipient brown rot decay may be related to loss in hemicellulose. This paper investigates the effect of decay on hemicellulose composition and the relationship to the mechanical properties ...

The potential of fungal pretreatment to improve fermentable sugar yields from wheat straw or Miscanthus was investigated. We assessed 63 fungal strains including 53 white-rot and 10 brown-rot fungi belonging to the Basidiomycota phylum in an original 12 day small-scale solid-state fermentation (SSF) experiment using 24-well plates. This method offers the convenience of one-pot processing of sam...

This paper describes a model of politeness between intentional agents developed from sociolinguistic observations of human-human interactions (Brown and Levinson, 1987) and suggests a method for applying it to human-machine interactions. Applications in the context of a medication reminder system are presented including data which suggest that the Brown and Levinson model provides good predicti...
