Challenges of teaching occupation: Introduction of an occupation focused teaching tool.
Occupational science is of importance to multiple disciplines due to its potential to contribute to understandings of complex social issues. âOccupationâ, as a key concept of occupational science, is recognised as being highly complex, making it challenging for students to develop a comprehensive understanding of the concept. Terminology of occupational science literature has been noted at times as using the terms occupation, purposeful activity and activity interchangeably, which further adds to the challenge of teaching the concept. This paper explores evolving definitions of occupation, challenges this evolution has created within education, and the potential use of occupation as a threshold concept. Consideration of a selection of pedagogic methods used in teaching the concept of occupation is briefly explored. The paper concludes with identification of a newly developed occupation-focused teaching tool as a proposed alternative approach to teaching the concept of occupation. The teaching tool was originally developed to teach occupation as a discrete concept, rather than the therapeutic use of occupation as taught in occupational therapy education. The tool is an analogy for occupation, and has utility in supporting the transformation of studentsâ understanding of the concept of occupation, commensurate to understandings of occupational science.N/
Teen Pregnancy: Addressing the Problem of Teen Pregnancy among Latinos
The United States continues to have the highest rates of teen pregnancy when compared to other nations despite declining rates over the last few years. The Latina population is disproportional affected by these higher rates. Latinas had the highest teen birth rate of all major ethnic groups in the United States with 83 births per 1,000 teens aged 15-19 in 2004 alone, a rate nearly double of the national rate at 41.1 In addition, the Latino population is the fastest growing ethnic group in the United States. Economic and cultural barriers have limited access to health care and teen pregnancy prevention and education programs for this population. The number of young Latina mothers and children who are poverty stricken or lack health care are like! y to see an increase as the teen birth rate increases. Moreover, there are several reasons that indicate why some Latina teens may want to become pregnant. Sex education is needed to lower teen pregnancy in this population but also to address some of the cultural, social and economic problems that may afflict this community. There are effective and promising programs that help tackle this issue, but there is more work to be done in public policy to continue these efforts. This paper takes a closer look at some of the issues surrounding teen pregnancy among Latinos and provides an overview of policy and programs.Master of Public Healt
The diversity and utility of amyloid fibrils formed by short amyloidogenic peptides
Amyloidogenic peptides are well known for their involvement in diseases such as type 2 diabetes and Alzheimer's disease. However, more recently, amyloid fibrils have been shown to provide scaffolding and protection as functional materials in a range of organisms from bacteria to humans. These roles highlight the incredible tensile strength of the cross-ÎČ amyloid architecture. Many amino acid sequences are able to self-assemble to form amyloid with a cross-ÎČ core. Here we describe our recent advances in understanding how sequence contributes to amyloidogenicity and structure. For example, we describe penta- and hexapeptides that assemble to form different morphologies; a 12mer peptide that forms fibrous crystals; and an eight-residue peptide originating from α-synuclein that has the ability to form nanotubes. This work provides a wide range of peptides that may be exploited as fibrous bionanomaterials. These fibrils provide a scaffold upon which functional groups may be added, or templated assembly may be performed
Next-Generation Raman tomography Instrument for Non-Invasive In Vivo Bone Imaging
Combining diffuse optical tomography methods with Raman spectroscopy of tissue provides the ability for in vivo measurements of chemical and molecular characteristics, which have the potential for being useful in diagnostic imaging. In this study a system for Raman tomography was developed and tested. A third generation microCT coupled system was developed to combine 10 detection fibers and 5 excitation fibers with laser line filtering and a Cytop reference signal. Phantom measurements of hydroxyapatite concentrations from 50 to 300 mg/ml had a linear response. Fiber placement and experiment design was optimized using cadaver animals with live animal measurements acquired to validate the systems capabilities. Promising results from the initial animal experiments presented here, pave the way for a study of longitudinal measurements during fracture healing and the scaling of the Raman tomography system towards human measurements

Time- and exercise-dependent gene regulation in human skeletal muscle
BACKGROUND: Skeletal muscle remodeling is a critical component of an organism's response to environmental changes. Exercise causes structural changes in muscle and can induce phase shifts in circadian rhythms, fluctuations in physiology and behavior with a period of around 24 hours that are maintained by a core clock mechanism. Both exercise-induced remodeling and circadian rhythms rely on the transcriptional regulation of key genes. RESULTS: We used DNA microarrays to determine the effects of resistance exercise (RE) on gene regulation in biopsy samples of human quadriceps muscle obtained 6 and 18 hours after an acute bout of isotonic exercise with one leg. We also profiled diurnal gene regulation at the same time points (2000 and 0800 hours) in the non-exercised leg. Comparison of our results with published circadian gene profiles in mice identified 44 putative genes that were regulated in a circadian fashion. We then used quantitative PCR to validate the circadian expression of selected gene orthologs in mouse skeletal muscle. CONCLUSIONS: The coordinated regulation of the circadian clock genes Cry1, Per2, and Bmal1 6 hours after RE and diurnal genes 18 hours after RE in the exercised leg suggest that RE may directly modulate circadian rhythms in human skeletal muscle
Viral suppression following switch to second-line antiretroviral therapy: associations with nucleoside reverse transcriptase inhibitor resistance and subtherapeutic drug concentrations prior to switch.
BACKGROUND: High rates of second-line antiretroviral treatment (ART) failure are reported. The association with resistance and nonadherence on switching to second-line ART requires clarification. METHODS: Using prospectively collected data from patients in South Africa, we constructed a cohort of patients switched to second-line ART (1 January 2003 through 31 December 2008). Genotyping and drug concentrations (lamivudine, nevirapine, and efavirenz) were measured on stored samples preswitch. Their association with viral load (VL) <400 copies/mL by 15 months was assessed using modified Poisson regression. RESULTS: One hundred twenty-two of 417 patients (49% male; median age, 36 years) had genotyping (n = 115) and/or drug concentrations (n = 80) measured. Median CD4 count and VL at switch were 177 cells/”L (interquartile range [IQR], 77-263) and 4.3 log10 copies/mL (IQR, 3.8-4.7), respectively. Fifty-five percent (n = 44/80) had subtherapeutic drug concentrations preswitch. More patients with therapeutic vs subtherapeutic ART had resistance (n = 73): no major mutations (3% vs 51%), nonnucleoside reverse transcriptase inhibitor (94% vs 44%), M184V/I (94% vs 26%), and ℠1 thymidine analogue mutations (47% vs 18%), all P = .01; and nucleoside reverse transcriptase inhibitor (NRTI) cross-resistance mutations (26% vs 13%, P = .23). Following switch, 68% (n = 83/122) achieved VL <400 copies/mL. Absence of NRTI mutations and subtherapeutic ART preswitch were associated with failure to achieve VL <400 copies/mL. CONCLUSIONS: Nonadherence, suggested by subtherapeutic ART with/without major resistance mutations, significantly contributed to failure when switching regimen. Unresolved nonadherence, not NRTI resistance, drives early second-line failure
