Abstract

Several studies reported high rates of psychiatric commorbidity among methadone patients. We examined the relationships of measures of psychopathology to outcomes of screening urine tests for cocaine, opiates, and benzodiazepines in a sample of 56 methadone patients. They also completed the Symptom Check List-90-Revised (SCL-90-R). The highest scales in the SCL-90-R profile of our patients were those indicating somatic discomfort, anger, phobic anxiety, paranoid ideation, and also obsessive-compulsive disorder symptoms (scores above the 39th per centile). The only significant correlations between urine tests and SCL-90-R psychopathology were those involving benzodiazepines: patients with urine tests positive for benzodiazepines had lower social self-confidence (r=0.48), were more obsessive-compulsive (r=0.44), reported a higher level of anger (r=0.41), of phobic tendencies (r=40), of anxiety (r=0.39), and of paranoid tendencies (r=0.38), and also reported more frequent psychotic symptoms (r=0.43).

Abstract

Purpose

This study aims to investigate the nutrient composition and cholesterol content of most popular fast foods sold in Qena city, Egypt with reference to their trans fatty acids contents.

Design/methodology/approach

Total 80 samples of fast foods were collected from various fast food restaurants in Qena city, Egypt. The samples were investigated for their nutritive quality by measuring moisture, protein, fat, ash, carbohydrate and energy content as described by the association of analytical chemists. The cholesterol content was determined using a spectrophotometer, while trans fatty acids were analyzed by gas chromatography using standard methods.

Findings

The study revealed a wide variation in the composition and nutritive value. On a fresh weight basis, moisture, protein, fat, carbohydrate and ash ranged from 45.9-55.0 (P < 0.001), 15.0-22.3 (P < 0.001), 13.1-15.7 (P = 0.034), 6.0-16.2 (P < 0.001) and 2.2-3.5 (P < 0.001), %w/w, respectively. The fast foods were very energy dense with calorie content varying from 236.5-281.1 (P < 0.001), Kcal/100 g. The mean values of cholesterol were between 15-17 mg/100 g (P = 0.398). The findings showed that fast foods had high total trans fatty acids content exceeding the Danish legal limit of 2 g/100 g of fat being in the range of 3.5 to 11.3 g per 100 g fat (P = 0.379). Elaidic acid is the predominant trans-isomer in industrially produced trans fatty acids. The concentrations of elaidic acid were high in all samples examined (P = 0.942).

Originality/value

This study has established the fact that fast foods are associated with high total energy intake, high intake of fat, trans fat and a higher proportion of calories being derived from total fat and trans-fat. Therefore, it is recommended to limit the intake of fast food.

Abstract

Purpose

The purpose of this study is to detect the effect of some natural cellulosic polymers in their nano forms with the addition of zinc oxide nanoparticles on restoring the lost mechanical strength of degraded papyrus without any harmful effects on the inks.

Design/methodology/approach

In the current study, the USB digital microscopy, scanning electron microscope, measurement of mechanical properties (tensile and elongation), pH measurement, color change and infrared spectroscopy were undertaken for the samples before and after treatment and aging.

Findings

In the current study, the USB digital microscopy, scanning electron microscope, measurement of mechanical properties (tensile and elongation), pH measurement, color change and infrared spectroscopy were undertaken for the samples before and after treatment and aging.

Originality/value

The effect of strengthening materials was studied on cellulose and carbon ink, which makes this study closer to reality as the manuscript is the consistent structure of cellulose and inks, whereas most of the literature stated the impact of consolidation materials on the strengthening the cellulosic supports without attention to their impact on inks.
