A multi-site trial of an electronic health integrated physical activity promotion intervention in breast and endometrial cancers survivors: MyActivity study protocol.

Despite the known benefits of moderate-to-vigorous physical activity (MVPA) for breast and endometrial cancer survivors, most are insufficiently active, interventions response is heterogeneous, and MVPA programming integration into cancer care is limited. A stepped care approach, in which the least resource-intensive intervention is delivered first and additional components are added based on individual response, is one strategy to enhance uptake of physical activity programming. However, the most effective intervention augmentation strategies are unknown.

CLIC-01: Manufacture and distribution of non-cryopreserved CAR-T cells for patients with CD19 positive hematologic malignancies.

Unlabelled: Access to commercial CD19 CAR-T cells remains limited even in wealthy countries like Canada due to clinical, logistical, and financial barriers related to centrally manufactured products. We created a non-commercial academic platform for end-to-end manufacturing of CAR-T cells within Canada's publicly funded healthcare system. We report initial results from a single-arm, open-label study to determine the safety and efficacy of in-house manufactured CD19 CAR-T cells (entitled CLIC-1901) in participants with relapsed/refractory CD19 positive hematologic malignancies.

The cross-domain functional organization of posterior lateral temporal cortex: insights from ALE meta-analyses of 7 cognitive domains spanning 12,000 participants.

The posterior lateral temporal cortex is implicated in many verbal, nonverbal, and social cognitive domains and processes. Yet without directly comparing these disparate domains, the region's organization remains unclear; do distinct processes engage discrete subregions, or could different domains engage shared neural correlates and processes? Here, using activation likelihood estimation meta-analyses, the bilateral posterior lateral temporal cortex subregions engaged in 7 domains were directly compared. These domains comprised semantics, semantic control, phonology, biological motion, face processing, theory of mind, and representation of tools.

Neurochemical and functional interactions for improved perceptual decisions through training.

Learning and experience are known to improve our ability to make perceptual decisions. Yet, our understanding of the brain mechanisms that support improved perceptual decisions through training remains limited. Here, we test the neurochemical and functional interactions that support learning for perceptual decisions in the context of an orientation identification task.

Multiple dimensions underlying the functional organization of the language network.

Understanding the different neural networks that support human language is an ongoing challenge for cognitive neuroscience. Which divisions are capable of distinguishing the functional significance of regions across the language network? A key separation between semantic cognition and phonological processing was highlighted in early meta-analyses, yet these seminal works did not formally test this proposition. Moreover, organization by domain is not the only possibility.

The missing voices of Indigenous Australians with autism in research.

The purpose of this Letter to the Editor is to raise awareness among those who read Autism about the limited amount of peer-reviewed literature on Aboriginal and Torres Strait Islander Australians living on the autism spectrum. This letter summarises the results of our search on Pubmed and Google Scholar for peer-reviewed literature on this subject. It then concludes by explaining why more research should be conducted on Aboriginal and Torres Strait Islander Australians living on the autism spectrum.

Classification of main meal patterns--a latent class approach.

Relatively little examination of the meals that are prepared in households has been conducted, despite their well-defined properties and widespread community interest in their preparation. The purpose of the present study was to identify the patterns of main meal preparation among Australian adult household meal preparers aged 44 years and younger and 45 years and over, and the relationships between these patterns and likely socio-demographic and psychological predictors. An online cross-sectional survey was conducted by Meat and Livestock Australia among a representative sample of people aged 18–65 years in Australia in 2011.

Structure and formation of the unusual sperm of Patelloida latistrigata (Mollusca : Patellogastropoda): implications for fertilization biology.

The structure of the spermatozoa and spermatogenesis of the lottiid limpet Patelloida latistrigata is described by transmission electron microscopy. Although the lengths of the spermatozoa (about 60 μm) and their head region (about 12 μm) are similar to those of other patellogastropods, the structure of the sperm head and midpiece are very different. The head consists of an unusually large acrosome (about 11-μm long) with a broad posterior invagination that houses the relatively small nucleus.

MusTRD can regulate postnatal fiber-specific expression.

Human MusTRD1alpha1 was isolated as a result of its ability to bind a critical element within the Troponin I slow upstream enhancer (TnIslow USE) and was predicted to be a regulator of slow fiber-specific genes. To test this hypothesis in vivo, we generated transgenic mice expressing hMusTRD1alpha1 in skeletal muscle. Adult transgenic mice show a complete loss of slow fibers and a concomitant replacement by fast IIA fibers, resulting in postural muscle weakness.

Transcription occurs in pulses in muscle fibers.

We report a novel mechanism of gene regulation in skeletal muscle fibers. Within an individual myofiber nucleus, not all muscle loci are transcriptionally active at a given time and loci are regulated independently. This phenomenon is particularly remarkable because the nuclei within a myofiber share a common cytoplasm.

Nerve-responsive troponin I slow promoter does not respond to unloading.

We examined the regulation of the troponin I slow (TnIs) promoter during skeletal muscle unloading-induced protein isoform transition, by using a transgenic mouse line harboring the -4,200 to +12 base pairs region of the human TnIs promoter. Eighteen female transgenic mice ( approximately 30 g body mass) were randomly divided into two groups: weight-bearing (WB) controls (n = 9) and hindlimb unloaded (HU; n = 9). The HU mice were tail suspended for 7 days.

Anti-Candida activity of a novel killer toxin from the yeast Williopsis mrakii.

A screening of putative killer yeast strains showed that spore-forming ascomycetous yeasts of the genera Pichia and Williopsis displayed the broadest range of activity against sensitive strains of Candida spp. and Saccharomyces cerevisiae. Williopsis mrakii (NCYC 500) showed extensive anti-Candida activity against strains isolated from clinical specimens.

Interactions between killer yeasts and pathogenic fungi.

A total of 17 presumptive killer yeast strains were tested in vitro for growth inhibitory and killing activity against a range of fungal pathogens of agronomic, environmental and clinical significance. Several yeasts were identified which displayed significant activity against important pathogenic fungi. For example, isolates of the opportunistic human pathogen, Candida albicans, were generally very sensitive to Williopsis mrakii killer yeast activity, whilst killer strains of Saccharomyces cerevisiae and Pichia anomala markedly inhibited the growth of certain wood decay basidiomycetes and plant pathogenic fungi.

A rapid colorimetric assay of killer toxin activity in yeast.

The pale yellow redox indicator 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) is reduced to a dark blue end-product, MTT-Formazan, by the mitochondrial dehydrogenases of living cells. MTT reduction can be measured spectrophotometrically at a wavelength of 570 nm and a method is described to assay the cidal activity of Williopsis mrakii killer toxin against sensitive cells of Candida glabrata. The MTT assay is rapid, quantitative and compares favourably with traditional plating techniques for the assessment of sensitive viability.

Cerebrovascular changes in a rat model of moderate closed-head injury.

We have developed and tested a rat (Wistar) model of moderate concussion. Concussion is produced by controlled and repeatable mechanical fixed, closed-head injury. Moderate concussion in this model is characterized by 4 to 10 minutes of unconsciousness, absence of skull fractures or brain contusions, and few, if any, acute neurologic symptoms.

The relevance of a First-World therapeutic drug monitoring service to the treatment of epilepsy in Third-World conditions.

In May 1988 a Therapeutic Drug Monitoring (TDM) service for anti-epileptic drugs was established at Prince Mshiyeni Memorial Hospital. This service was offered as a multidisciplinary team approach involving sisters, doctors, social workers and pharmacists at an epilepsy clinic. Statistics gathered over a 13-month period showed that: (i) epileptic patient numbers increased from 52 to 211 per 4-week cycle, while patients requiring TDM decreased from 40 to 20 per cycle; (ii) phenytoin was the most frequently prescribed anticonvulsant, followed by carbamazepine and phenobarbitone, throughout the period; (iii) TDM did not alter prescribing patterns--approximately 90% of patients were on monotherapy at the beginning and at the end of the assessment period; (iv) 471 serum levels were measured in 280 patients over 13 months.

An Assessment of Compressive Neck Loads Under Injury-Producing Conditions.

Injury reference curves for axial compressive forces on the neck were derived from impact tests of a spring-loaded tackling block on football helmets. Results suggest that helmets, especially those with resilient liners, reduce these forces.

Spinal injury at the level of the third and fourth cervical vertebrae from football.

Acute traumatic lesions of the spine at the third and fourth cervical levels without associated fracture are not common. The eight lesions in this report occurred as a result of injuries sustained during tackle football. They included acute intervertebral disc herniation, anterior subluxation of the third cervical vertebra on the fourth, unilateral dislocation of the joint between the articular processes, and bilateral dislocation of the joints between the articular processes.

National Operating Committee on Standards for Athletic Equipment football helmet certification program.

Wayne State University, Department of Neurosurgery, was contracted in 1971 by NOCSAE to develop voluntary standards for football helmets. Preliminary tests of representative football helmets on cadavers and the Z-90 metal head form showed that a more realistic head model was necessary before it was possible to understand helmet performance. A synthetic model was developed which approached human cadaver performance and at the same time was more rugged and repeatable than a cadaver head.
