Effects of Aromatic Concentration on Methane Fermentation

The anaerobic biodegradability and toxicity of fourteen aromatic compounds were evaluated over a wide range of concentrations using a serum bottle technique. Benzene, toluene, and all three isomers of xylene were not significantly degraded to methane in a phenol-enriched culture. Complete degradation of 1000 mg/L phenol, 800 mg/L catechol, 100 mg/L 2-NP, 100 mg/L 3- NP, and 100 mg/L 4-NP was observed within two months while depletion of 100 mg/L resorcinol and 1000 mg/L hydroquinone required more than six and eight months incubation, respectively. None of the three isomers of chlorophenol were degraded in the phenol-enriched culture. Batch toxicity assay revealed that the phenol-enriched culture was more susceptible to inhibition caused by substituted phenols than the acetate-enriched culture. In general, the inhibitory effects on both phenol degradation and acetate utilization did not vary significantly with the isomer but rather with the substituted group. The degree of inhibition was in the order of nitrophenols \u3e chlorophenols \u3e hydroxyphenols. The Haldane inhibition model was used to fit experimental data from phenol and catechol. The inhibition of phenol degradation by chlorophenols, resorcinol, and hydroquinone was described rather well by a Monod-type, noncompetitive model

Lymphocytic Esophagitis in Nonachalasia Primary Esophageal Motility Disorders: Improved Criteria, Prevalence, Strength of Association, and Natural History.

Lymphocytic esophagitis (LE) is a histologic pattern with no established clinical correlates in the majority of patients. The goal of this study was to evaluate the association between nonachalasia primary esophageal motility disorders (PEMD) and LE. Sixty-nine patients with PEMD and esophageal biopsies, including 22 with nutcracker esophagus, 33 with ineffective motility, and 14 with diffuse spasm, constituted the study group. The control group consisted of 70 patients with severe dysmotility-negative gastroesophageal reflux disease requiring referral for Nissen fundoplication. To improve the criteria for LE, a lymphocyte reference range at different esophageal levels was first established in 17 healthy volunteers. The cutoffs for normal intraepithelial lymphocytes, defined as lymphocyte levels not exceeding mean level±2 SDs, were set at 62, 46, and 41 lymphocytes per high-power field at 0 to 2, 5, and 10 cm above the gastroesophageal junction, respectively. Predominantly focal peripapillary LE was observed in approximately 40% of patients with nutcracker esophagus or diffuse spasm and in 20% of patients with ineffective motility, in comparison with 4% of patients with dysmotility-negative gastroesophageal reflux disease (P<0.035 vs. any subtype of PEMD). Overall, LE was strongly associated with PEMD in multivariate analysis (adjusted odds ratio, 7.93; 95% confidence interval, 2.26-27.9; P=0.001). LE had a chronic course in 56% of the patients with follow-up biopsies. In conclusion, LE has a strong association with PEMD, suggesting the utility of LE in raising the possibility of PEMD

Is there still a place for the concept of therapeutic regression in psychoanalysis?

The author uses his own failure to find a place for the idea of therapeutic regression in his clinical thinking or practice as the basis for an investigation into its meaning and usefulness. He makes a distinction between three ways the term ‘regression’ is used in psychoanalytic discourse: as a way of evoking a primitive level of experience; as a reminder in some clinical situations of the value of non-intervention on the part of the analyst; and as a description of a phase of an analytic treatment with some patients where the analyst needs to put aside normal analytic technique in order to foster a regression in the patient. It is this third meaning, which the author terms “therapeutic regression” that this paper examines, principally by means of an extended discussion of two clinical examples of a patient making a so-called therapeutic regression, one given by Winnicott and the other by Masud Khan. The author argues that in these examples the introduction of the concept of therapeutic regression obscures rather than clarifies the clinical process. He concludes that, as a substantial clinical concept, the idea of therapeutic regression has outlived its usefulness. However he also notes that many psychoanalytic writers continue to find a use for the more generic concept of regression, and that the very engagement with the more particular idea of therapeutic regression has value in provoking questions as to what is truly therapeutic in psychoanalytic treatment

The role of empathy in psychoanalytic psychotherapy: A historical exploration

Empathy is one of the most consistent outcome predictors in contemporary psychotherapy research. The function of empathy is particularly important for the development of a positive therapeutic relationship: patients report positive therapeutic experiences when they feel understood, safe, and able to disclose personal information to their therapists. Despite its clear significance in the consulting room and psychotherapy research, there is no single, consensual definition of empathy. This can be accounted by the complex and multi-faceted nature of empathy, as well as the ambiguous and conflicting literature surrounding it. This paper provides a historical exploration of empathy and its impact on the therapeutic relationship across the most influential psychoanalytic psychotherapies: classic psychoanalysis, person-centered therapy and self-psychology. By comparing the three clinical schools of thought, the paper identifies significant differences in the function of transference and therapist’s role. Then, drawing on the different clinical uses of empathy, the paper argues that the earlier uses of empathy (most notably through Jaspers’ and Freud’s writings) are limited to its epistemological (intellectual or cognitive) features, whilst person-centered and self-psychology therapies capitalise on its affective qualities. Finally, the paper provides a rationale for further study of the overarching features of empathy in contemporary psychotherapy research

The usability attributes and evaluation measurements of mobile media AR (augmented reality)

This research aims to develop a tool for creating user-based design interfaces in mobile augmented reality (MAR) education. To develop a design interface evaluation tool, previous literature was examined for key design elements in the educational usage of MAR. The evaluation criteria identified were presence, affordance, and usability. The research used a focus group interview with 7 AR experts to develop a basic usability evaluation checklist, which was submitted to factor analysis for reliability by 122 experts in practice and academia. Based on this checklist, a MAR usability design interface test was conducted with seven fourth-grade elementary students. Then, it conducted follow-up structured interviews and questionnaires. This resulted in 29 questions being developed for the MAR interface design checklist.ope

The heritage of slavery in British jazz festivals

This article explores site-specific heritage questions of the contemporary cultural practice of festivals of jazz – a key transatlantic music form – by bringing together three areas for discussion and development: questions of slavery heritage and legacy; the location, built environment and (touristic) offer of the historic city; and the contemporary British jazz festival, its programme and the senses or silences of (historical) situatedness in the festival package. Other artistic forms, cultural practices and festivals are involved in self-reflexive efforts to confront their own pasts; such are discussed as varying processes of the decolonisation of knowledge and culture. This provides the critical and cultural context for consideration of the jazz festival in the Georgian urban centre. Preliminary analysis of relevant jazz festivals’ programmes, commissions and concerts leads to interrogating the relationship – of silence, of place – between jazz in Britain, historic or heritage locations and venues, and the degree or lack of understanding of the transatlantic slave trade. The heritage centres clearly associated with the slave trade that also have significant (jazz) festivals referred to include Bristol, Cheltenham, Edinburgh, Glasgow, Hull, Lancaster, Liverpool, London, and Manchester
