ABSTRACT
Neuromyelitis optica spectrum disorders (NMOSDs) usually manifest with features of long-segment myelitis and/or optic neuritis. Area postrema involvement presents with nausea, vomiting, and intractable hiccups. Cerebral cortical involvement is a relatively uncommon phenomenon. This report describes an interesting case of aquaporin 4 antibody positive NMOSD with extensive cerebral cortical involvement in addition to area postrema and cervicomedullary lesions observed on magnetic resonance imaging. Following immunosuppressive therapy, good clinical response and near-complete resolution of brain imaging abnormalities were observed.

ABSTRACT
Empathy, as an essential personality trait of human beings, has been studied rigorously in the field of nursing and medical sciences. Nowadays, universities are also endeavoring to develop empathy with particular courses or tailored content among the students. The English language classroom acts as a dynamic platform to impart education for empathy. Yet there is a paucity of research related to the outcomes of such initiatives. The current study revolved around an English language course that is primarily designed to improve students' proficiency in English required for them to be empowered with the compatibility of tertiary education. The secondary focus of the course concerned the cultivation of empathy that is inevitable not only for the academic journey but also for social wellbeing. The present study was designed to investigate the contents, based on theoretical grounds, of the English language classroom and to trace the outcomes of such an empathy-teaching. A phenomenological approach was adopted to conduct the study, in which document analysis and semi-structured interviews with 10 participants shaped the instrumentation of data collection. The current study adopted thematic analysis to analyze the semi-structured interview data. The findings projected that the contents harnessed to cultivate empathy corresponded to the theoretical aspects of empathy development. The semi-structured interview data was a testimony of the nature of empathy practice inculcated among undergraduate students.
ABSTRACT
Yeast strains are commonly associated with sugar rich environments. Various fruit samples were selected as source for isolating yeast cells. The isolated cultures were identified at Genus level by colony morphology, biochemical characteristics and cell morphological characters. An attempt has been made to check the viability of yeast cells under different concentrations of ethanol. Ethanol tolerance of each strain was studied by allowing the yeast to grow in liquid YEPD (Yeast Extract Peptone Dextrose) medium having different concentrations of ethanol. A total of fifteen yeast strains isolated from different samples were used for the study. Seven strains of Saccharomyces cerevisiae obtained from different fruit sources were screened for ethanol tolerance. The results obtained in this study show a range of tolerance levels between 7%-12% in all the stains. Further, the cluster analysis based on 22 RAPD (Random Amplified polymorphic DNA) bands revealed polymorphisms in these seven Saccharomyces strains.
ABSTRACT
The enzymatic reduction of Cr(VI) to Cr(III) by Cr(VI) resistant bacteria followed by chemical precipitation constitutes the ChromeBac system. Acinetobacter haemolyticus was immobilized onto carrier material inside a 0.2m(3) bioreactor. Neutralized electroplating wastewater with Cr(VI) concentration of 17-81 mg L(-1) was fed into the bioreactor (0.11-0.33 m(3)h(-1)). Complete Cr(VI) reduction to Cr(III) was obtained immediately after the start of bioreactor operation. Together with the flocculation, coagulation and filtration, outflow concentration of less than 0.02 mg Cr(VI)L(-1) and 1mg total CrL(-1) were always obtained. Performance of the bioreactor was not affected by fluctuations in pH (6.2-8.4), Cr(VI) (17-81 mg L(-1)), nutrient (liquid pineapple waste, 1-20%v/v) and temperature (30-38 degrees C). Standby periods of up to 10 days can be tolerated without loss in activity. A robust yet effective biotechnology to remove chromium from wastewater is thus demonstrated.
