An evaluation of subjective experiences, effects and overall satisfaction with clozapine treatment in a UK forensic service

Objectives: Patients prescribed clozapine were surveyed to assess (a) the effects, both positive and adverse, and overall satisfaction with clozapine in comparison to previously prescribed antipsychotics and (b) the relative significance of effects experienced, both positive and adverse, in terms of impact on subjective well-being. Methods: A total of 56 male patients prescribed clozapine at a forensic psychiatric hospital were surveyed using a 27-item questionnaire. All patients had been prescribed clozapine for a minimum of 3 months. Respondents were asked to rate effects and satisfaction with clozapine treatment in comparison with previously prescribed antipsychotic medication on a five-point scale. Respondents were also asked to rate effects experienced with clozapine treatment in terms of impact on subjective well-being on a five-point scale. Results: A total of 89% of respondents reported greater satisfaction with clozapine than with previously prescribed antipsychotic medication. A majority of patients reported positive effects in terms of an improvement in their quality of life (68%) and social abilities (52%) with clozapine in comparison with previously prescribed antipsychotics. Nocturnal hypersalivation (84%) and weight gain (57%) were the most common adverse effects. Hedonic responses were assessed for each effect in order to determine the associated subjective experiences. The most positive hedonic responses were for quality of life, mood and alertness. In terms of adverse impact on subjective well-being, nocturnal hypersalivation ranked highest. Conclusions: Patients in a UK forensic sample are largely satisfied with clozapine treatment. The subjective effects of clozapine treatment should be taken into account by clinicians when assessing response. This may provide an opportunity to highlight the positive changes and prioritize management of the most undesirable adverse effects, which is likely to promote compliance and improve longer term treatment outcomes

Uncertainties of size measurements in electron microscopy characterization of nanomaterials in foods

Electron microscopy is a recognized standard tool for nanomaterial characterization, and recommended by the European Food Safety Authority for the size measurement of nanomaterials in food. Despite this, little data have been published assessing the reliability of the method, especially for size measurement of nanomaterials characterized by a broad size distribution and/or added to food matrices. This study is a thorough investigation of the measurement uncertainty when applying electron microscopy for size measurement of engineered nanomaterials in foods. Our results show that the number of measured particles was only a minor source of measurement uncertainty for nanomaterials in food, compared to the combined influence of sampling, sample preparation prior to imaging and the image analysis. The main conclusion is that to improve the measurement reliability, care should be taken to consider replications and matrix removal prior to sample preparation

Radioautographic Evidence of 3H-Tryptophan Incorporation in Secretory Cells of Rat Submandibular Glands

Tritiated tryptophan was injected intravenously into male rats, and the submandibular glands were removed at time intervals up to three hours after injection. Grain counts were made on light and electron microscope radioautographs to determine the effects on the amino acid.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67201/2/10.1177_00220345710500064601.pd

Focal Plane Array Sensor for Imaging Infrared Seeker of Antitank Guided Missile

Technological issues and Processes for fabrication of mercury cadmium telluride detector arrays, charge coupled device readout arrays and integration of these into a focal plane array sensor have been discussed. Mini arrays of 16 X 16 size have been realised and tested to prove the technology and process schedule with a view to scaling up this for larger arrays to be used in the antitank guided missile

Mob Programming – A Promising Innovation in the Agile Toolkit

Mob programming is a new agile practice that is attracting the attention of software community. This paper presents an overview of mob programming, its benefits and risks identified by its proponents and early adopters and suggests areas for future academic research that could help establish its efficacy and theoretical rationale. The paper also presents the results of text analysis done on the extant literature on the subject

RAPD-PCR based genomic characterization of two populations of Culex quinquefasciatus (Diptera : Culicidae)

The present paper deals with the RAPD-PCR based genomic characterization of Culex quinquefasciatus Say which is a major vector of filariasis in several parts of the Indian subcontinent. One population of the test organism used in the study was procured from Goa (pop.A) while the other (pop.B) was collected from a village Nadasahib (20 kms from Chandigarh). The RAPD-PCR amplification of whole body homogenate of freshly hatched individual specimens was carried out by using three random primers: primer I- 5’- GTCCCGACGA – 3’; primer II- 5’– TGATCCCTGG – 3’ and primer III- 5’- GTGACGTAGG – 3’. Primer I produced 5 distinct bands from the DNA of pop. A, whose base composition ranged from 200-1000 bp. Likewise, 7 bands ranging from 130-750 bp and 4 bands ranging from 270-950 bp were generated with primers II and III respectively. In case of pop.B, a total of 8 bands ranging from 200-1000 bp were generated with primer I. Similarly, a total of 6 bands ranging from 250-900 bp with primer II and 4 bands ranging from 180-950 bp with primer III were produced. Based on the bandsharing coefficient and the application of Nearest Neighbour Joining (NJ) analysis it was found that primer Iwas more suitable for detecting genomic differences at the species and generic levels while primer II was ideal for detecting variations in the number of bp in RAPD generated bands among different populations of Cx. quinquefasciatus

Relationships among musical aptitude, digit ratio and testosterone in men and women

Circulating adult testosterone levels, digit ratio (length of the second finger relative to the fourth finger), and directional asymmetry in digit ratio are considered sexually dimorphic traits in humans. These have been related to spatial abilities in men and women, and because similar brain structures appear to be involved in both spatial and musical abilities, neuroendocrine function may be related to musical as well as spatial cognition. To evaluate relationships among testosterone and musical ability in men and women, saliva samples were collected, testosterone concentrations assessed, and digit ratios calculated using standardized protocols in a sample of university students (N = 61), including both music and non-music majors. Results of Spearman correlations suggest that digit ratio and testosterone levels are statistically related to musical aptitude and performance only within the female sample: A) those females with greater self-reported history of exposure to music (p = 0.016) and instrument proficiency (p = 0.040) scored higher on the Advanced Measures of Music Audiation test, B) those females with higher left hand digit ratio (and perhaps lower fetal testosterone levels) were more highly ranked (p = 0.007) in the orchestra, C) female music students exhibited a trend (p = 0.082) towards higher testosterone levels compared to female non-music students, and D) female music students with higher rank in the orchestra/band had higher testosterone levels (p = 0.003) than lower ranked students. None of these relationships were significant in the male sample, although a lack of statistical power may be one cause. The effects of testosterone are likely a small part of a poorly understood system of biological and environmental stimuli that contribute to musical aptitude. Hormones may play some role in modulating the phenotype of musical ability, and this may be the case for females more so than males
