Notes on Australian Bombyliidae, mostly from the manuscript papers of the late Arthur White

The manuscript papers of the late Arthur White consist of (1) contributions that have already been published; (2) a very large mass of compiled notes and descriptions, interspersed amongst which are (3) a few pages of original material that have not been published, and that contain certain information based upon the examination of Walker's types in the British Museum. Notes on the types of earlier described species are of utmost importance, but White limited his observations almost entirely to those characters that he could use in keys, and often a number of species included by him under a genus also include some he has never seen. It is difficult to judge how much of the keys is based on observation and examination of the type material, and how much on compilations from other works. Owing to this confusion, White's manuscript cannot be compiled into a condition suitable for publication as an independent paper. I have therefore considered it advisable to publish White's records with my own, and to accept that which appears to me to be original, and within the probability of being correct. The keys and notes taken from White's manuscript are indicated so that it can be readily understood how much of my paper is to be attributed to White's researches. So far only manuscript containing Bombyliidae and Nemestrinida has been found to contain unpublished matter, and from the information given in the former family, I find it necessary to amend my catalogue on the Bombyliidae which was previously published in these Proceedings; some alterations which are the result of other researches are also included

Notes on the genus Pelecorhynchus

During December, 1914, and January, 1915, I procured three species of this interesting and rare genus Pelecorhynchus. Two of them are already recorded from Tasmania ; the third is new to Tasmania. The three species are P. eristaloides walk., P. Nigripennis ricardo and P. fusconiger walk

List of the Tenison Woods types of recent mollusca in the Tasmanian Museum

Until recently all types of the Tenison Woods Marine Mollusca were included in the general collections of Tasmanian shells in the Museum, and in consequence some were lost and others broken. The fresh-water shells were in a drawer in the Curator's office, mixed with much miscellaneous material, and in a very dilapidated condition. Very few specimens were marked type in Tenison Woods' handwriting (specimens so marked are recorded as such), the majority being marked by a committee of Conchologists formed for the purpose, particulars of which are given in the paper by Mr. W. L. May, Proc. Roy. Soc. Tasm. 1902. Unless otherwise stated, specimens in this list are marked "type". The Tenison Woods' fresh-water shells have mostly, if not all, sunk into synonomy, and there is room for considerable investigation on the Tasmanian fresh-water shells, as nothing apparently has been done since Tenison Woods' time

Novel colorectal endoscopic in vivo imaging and resection practice: a short practice guide for interventional endoscopists

Colorectal cancer remains a leading cause of cancer death in the UK. With the advent of screening programmes and developing techniques designed to treat and stage colorectal neoplasia, there is increasing pressure on the colonoscopist to keep up to date with the latest practices in this area. This review looks at the basic principles behind endoscopic mucosal resection and forward to the potential endoscopic tools, including high-magnification chromoscopic colonoscopy, high-frequency miniprobe ultrasound and confocal laser scanning endomicroscopic colonoscopy, that may soon become part of routine colorectal cancer management

Desmosomal cadherins in zebrafish epiboly and gastrulation

<p>Abstract</p> <p>Background</p> <p>The desmosomal cadherins (DCs), desmocollin (Dsc) and desmoglein (Dsg), are the adhesion molecules of desmosomes, intercellular adhesive junctions of epithelia and cardiac muscle. Both the DCs and desmosomes have demonstrably essential roles in mammalian development. In order to initiate their study in a more tractable developmental system we have characterised zebrafish DCs and examined their roles in early zebrafish development.</p> <p>Results</p> <p>We find that zebrafish possess one Dsc, the orthologue of mammalian Dsc1, which we designate zfDsc. Unlike mammalian Dscs, zfDsc exists only as the "a" form since it lacks the alternatively-spliced mini-exon that shortens the cytoplasmic domain to produce the "b" form. Zebrafish possess two Dsgs, designated zfDsgα and zfDsgβ, orthologues of mammalian Dsg2. They show 43.8% amino acid identity and the α form has a 43 amino acid glycine-rich sequence of unknown function in its extracellular domain. Both zfDsc and zfDsgα were present as maternal and zygotic transcripts whereas zfDsgβ was first expressed from 8 hours post-fertilisation (hpf). All three transcripts were present throughout subsequent stages of development. Morpholino knockdown of both zfDsc and zfDsgα expression produced similar defects in epiboly, axis elongation and somite formation, associated with abnormal desmosomes or reduced desmosome numbers.</p> <p>Conclusions</p> <p>These results demonstrate an important role for DCs and desmosomes in the early morphogenesis of the zebrafish embryo, provide a basis for more detailed analysis of their role and raise interesting questions relating to the evolution and functional significance of DC isoforms.</p

Performing Marginal Identities: Understanding the Cultural Significance of Tawa\u27if and Rudali Through the Language of the Body in South Asian Cinema

This thesis examines the representation of the lives and performances of tawa\u27if and rudali in South Asian cinema to understand their marginalization as performers, and their significance in the collective consciousness of the producers and consumers of Indian cultural artifacts. The critical textual analysis of six South Asian films reveals these women as caste-amorphous within the system of social stratification in India, and therefore captivating in the potential they present to achieve a complex and multi-faceted definition of culture. Qualitative interviews with 4 Indian classical dance instructors in Portland, Oregon and performative observations of dance events indicate the importance of these performers in perpetuating and developing Indian cultural artifacts, and illustrate the value of a multi-layered, performative methodological approach. These findings suggest that marginality in performance is a useful and dynamic site from which to investigate the processes of cultural communication, producing findings that augment sole textual analysis
