Fast forward to the end: Stories of the cassette magazine

Although they made up a significant share of the retail music market from the 60s to the 90s, and were often used as promotional and marketing tools, cassettes became re-configured in the 80s as an integral component of cassette magazines. Binding sound, music, talk, text, visual art and design, they were a truly innovative interdisciplinary form. This paper explores the history of these artefacts with particular emphasis on the Brisbane underground music scene of the late 70s and 80s, and discusses their significance in as a bridge between the music scene and art scenes of this period.

Design and construction of an in-plant activation cassette for transgene expression and recombinant protein production in plants

Virus-based transgene expression systems have become particularly valuable for recombinant protein production in plants. The dual-module in-plant activation (INPACT) expression platform consists of a uniquely designed split-gene cassette incorporating the cis replication elements of Tobacco yellow dwarf geminivirus (TYDV) and an ethanol-inducible activation cassette encoding the TYDV Rep and RepA replication-associated proteins. The INPACT system is essentially tailored for recombinant protein production in stably transformed plants and provides both inducible and high-level transient transgene expression with the potential to be adapted to diverse crop species. The construction of a novel split-gene cassette, the inducible nature of the system and the ability to amplify transgene expression via rolling-circle replication differentiates this system from other DNA- and RNA-based virus vector systems used for stable or transient recombinant protein production in plants. Here we provide a detailed protocol describing the design and construction of a split-gene INPACT cassette, and we highlight factors that may influence optimal activation and amplification of gene expression in transgenic plants. By using Nicotiana tabacum, the protocol takes 6-9 months to complete, and recombinant proteins expressed using INPACT can accumulate to up to 10% of the leaf total soluble protein.

A split cassette attachment for recording all the reflections on the upper level Weissenberg photographs either as elongated or as contracted spots

A split-cassette arrangement has been incorporated in the Weissenberg camera for recording all reflections on the upper level photographs either as elongated or as contracted spots. This arrangement employs two semicylindrical cassettes which are separated by a horizontal plane. These half-cassettes are translated in opposite directions. A suitable split-cassette attachment has been constructed for the Unicam Weissenberg goniometer S-35 The subject of 'displaced-film' Weissenberg photograph is also discussed.

Novel Rearrangements in the Staphylococcal Cassette Chromosome Mec Type V Elements of Indian ST772 and ST672 Methicillin Resistant Staphylococcus aureus Strains

Staphylococcus aureus is a commensal gram positive bacteria which causes severe and non severe infections in humans and livestock. In India, ST772 is a dominant and ST672 is an emerging clone of Staphylococcus aureus. Both cause serious human diseases, and carry type V SCCmec elements. The objective of this study was to characterize SCCmec type V elements of ST772 and ST672 because the usual PCR methods did not amplify all primers specific to the type. Whole genome sequencing analysis of seven ST772 and one ST672 S. aureus isolates revealed that the SCCmec elements of six of the ST772 isolates were the smallest of the extant type V elements and in addition have several other novel features. Only one ST772 isolate and the ST672 isolate carried bigger SCCmec cassettes which were composites carrying multiple ccrC genes. These cassettes had some similarities to type V SCCmec element from M013 isolate (ST59) from Taiwan in certain aspects. SCCmec elements of all Indian isolates had an inversion of the mec complex, similar to the bovine SCCmec type X. This study reveals that six out of seven ST772 S. aureus isolates have a novel type V (5C2) SCCmec element while one each of ST772 and ST672 isolates have a composite SCCmec type V element (5C2&5) formed by the integration of type V SCCmec into a MSSA carrying a SCC element, in addition to the mec gene complex inversions and extensive recombinations.

A modulação da via do AMPc/PKA altera a morfologia da oligodendroglia e a distribuição das proteínas CNPase e MAG in vitro

A diferenciação da oligodendroglia depende de alterações coordenadas no citoesqueleto e na sua relação com a membrana plasmática, um componente importante para a formação da bainha de mielina. A 23 nucleotídeo cíclico 3 fosfodiesterase (CNPase) está relacionada com a organização do citoesqueleto, sendo uma proteína ancoradoura de microtúbulos na membrana plasmática. In vitro, a CNPase compõe, com a F-actina e os microtúbulos, as estruturas semelhantes a nervuras ou os componentes radiais. A glicoproteína associada a mielina (MAG), também é importante para a formação dos véus de membrana e está associada a CNPase e a tubulina. Além disso, as três proteínas podem ser reguladas pela via de sinalização do AMPc/PKA. Buscando avaliar os efeitos da via do AMPc/PKA na regulação da diferenciação oligodendroglial, culturas de hemisférios cerebrais com 5 dias foram tratadas por 30 min ou 24 h com o inibidor (SQ22356-SQ [1 M]) ou com o ativador (forscolina [10M]) da adenilato ciclase ou com o inibidor da PKA, H-89 [1 M]. A oligodendroglia foi identificada pelo anticorpo anti-CNPase e por sua morfologia. Com 30 min de tratamento com forscolina, as células das culturas tratadas apresentaram prolongamentos maiores e menos véus de membrana quando comparadas às culturas controle. O tratamento com SQ também causou um aumento no tamanho dos prolongamentos e o tratamento com H-89 causou a redução no tamanho dos prolongamentos e nos véus de membrana. Com 24 h, as células tratadas com forscolina apresentaram poucos prolongamentos, já as culturas tratadas com SQ apresentaram um aumento no tamanho do prolongamento e as tratadas com H-89 demonstraram redução no véu de membrana. Observamos também alterações na distribuição da CNPase, tubulina e MAG, a primeira apresentou uma concentração próxima ao núcleo depois dos dois tempos de tratamento com H-89, o mesmo ocorreu com a tubulina. A CNPase adquiriu ainda um padrão puntiforme depois de 24 h de tratamento com ambos os inibidores. A MAG apresentou um aumento na concentração próximo ao núcleo depois de 30 min de tratamento com forscolina e SQ. O tratamento com SQ também reduziu a distribuição da MAG nos véus de membrana. A mesma redução foi observada depois de 24 h de tratamento com H-89. Esses resultados reforçam a participação da via do AMPc/PKA no desenvolvimento da oligodendroglia, incluindo a formação dos prolongamentos, suas ramificações e ainda a formação dos véus de membrana, com prováveis consequências na formação e manutenção da bainha de mielina.

Impact of ATP-binding cassette, subfamily B, member 1 pharmacogenetics on tacrolimus-associated nephrotoxicity and dosage requirements in paediatric patients with liver transplant

Importance of the field: Tacrolimus is the most commonly used immunosuppressive agent following solid-organ transplantation in children. Its clinical use, however, is complicated by side effects (mainly nephrotoxicity), narrow therapeutic index and pharmacokinetic variability which can result in an increased risk of treatment failure or toxicity. Studies examining inter-individual differences in the expression of the ABCB1 (ATP-binding cassette, subfamily B, member 1) gene (which encodes the drug transporter, P-gp) and its genetic polymorphisms have attempted to elucidate variations in tacrolimus response and disposition in children.

The effect of metal transfer modes and shielding gas composition on the emission of ultraafine particles in MAG steel welding

The present study aims to characterize ultrafine particles emitted during gas metal arc welding of mild steel and stainless steel, using different shielding gas mixtures, and to evaluate the effect of metal transfer modes, controlled by both processing parameters and shielding gas composition, on the quantity and morphology of the ultrafine particles. It was found that the amount of emitted ultrafine particles (measured by particle number and alveolar deposited surface area) are clearly dependent from the main welding parameters, namely the current intensity and the heat input of the Welding process. The emission of airborne ultrafine particles increases with the current intensity as fume formation rate does. When comparing the shielding gas mixtures, higher emissions were observed for more oxidizing mixtures, that is, with higher CO2 content, which means that these mixtures originate higher concentrations of ultrafine particles (as measured by number of particles. by cubic centimeter of air) and higher values of alveolar deposited surface area of particles, thus resulting in a more hazardous condition regarding welders exposure.
