The length-tension diagrams of human oblique muscles in trochlear palsy and strabismus sursoadductorius

We determined the relation between length and tension in detached oblique muscles of 16 strabismus patients that underwent surgery, before and during contraction evoked by intravenous administration of succinylcholine. We frequently found a nonlinear relation between length and tension, unlike our previous findings in recti. In superior oblique palsies, the superior oblique was found, before injection of succinylcholine, to be stiff after elongation, and did not contract after injection of succinylcholine, while the ipsilateral inferior oblique contract after injection of succinylcholine, but with a higher spring constant than did usual. In 3 cases the superior oblique contracted vividly after administration of succinylcholine despite the presence of excyclotropia, stereopsis, torticollis (2 cases) and a hypertropia that increased in adduction, in downgaze, in adduction-and-downgaze and on ipsilateral head-tilt. The finding of a vividly contracting superior oblique is incompatible with the diagnosis of a complete superior oblique palsy. We conclude that some of the cases diagnosed as congenital superior oblique palsy, having a hypertropia increasing in adduction, in downgaze, in adduction-and-downgaze and on ipsilateral head-tilt, are in fact cases of unilateral strabismus sursoadductorius (upshoot in adduction), a non-paretic motility disorder

The role of Australian local governments in creating a healthy, sustainable and equitable food system: Results of a policy mapping study in New South Wales and Victoria

Transformation of the food system is required to ensure food security for an increasing global population within finite planetary and climate boundaries. While much attention has been paid to how state and national governments can influence food systems, less is known about the role of Australian local governments in addressing these health, sustainability, and equity challenges. This report provides a summary of a policy mapping study conducted by researchers from the University of Sydney, University of Wollongong, and William Angliss Institute of TAFE (Melbourne)

Generalized oscillator strength for Na 3s-3p transition

Generalized oscillator strengths (GOS's) for the Na $3s -3p$ transition have been investigated using the spin-polarized technique of the random phase approximation with exchange (RPAE) and the first Born approximation (FBA), focussing our attention on the position of the minimum. Intershell correlations are found to influence the position of the minimum significantly, but hardly that of the maximum. The RPAE calculation predicts for the first time the positions of the minimum and maximum at momentum transfer, $K$ values of 1.258 a.u. and 1.61 a.u., respectively. The former value is within the range of values extracted from experimental measurements, $K=1.0-1.67$ a.u.. We recommend careful experimental search for the minimum around the predicted value for confirmation.Comment: 11 pages, 2figure

Inclusão, democracia e novo-desenvolvimentismo : um balanço histórico

Este trabalho analisa o processo do desenvolvimentismo brasileiro compreendido entre a fase clássica dos anos 1950 até a perspectiva atual do novo-desenvolvimentismo, privilegiando o papel e a função desempenhadas pelo tema da democracia e da inclusão distributiva em cada arranjo. Na primeira seção, analisa-se a constelação semântica que envolve os termos progresso e desenvolvimento, procurando separá-los do processo/projeto denominado desenvolvimentismo. Na segunda seção, discutem-se as fases e características centrais do velho e do novo-desenvolvimentismo brasileiro e a perspectiva de sua subdivisão em três ondas históricas, separadas pelo aspecto político democrático e pelo tema da redistribuição. Por último, apresentam-se algumas considerações sobre o novo-desenvolvimentismo em seu arranjo democrático-inclusivo.This paper analyzes the process of the Brazilian developmentalism between the classical phase of the 1950s to the current perspective of new developmentalism, emphasizing the role and function played by the theme of democracy and distributive inclusion in every arrangement. In the first section, it is analyzed the semantic constellation involving the terms progress and development, seeking to separate them from the process / project called developmentalism. In the second section, it is discussed the phases and the central features of the old and the new Brazilian developmentalism and the prospect of their subdivision into three historical waves, separated by the political democratic aspect and by the theme of redistribution. Finally it presents some considerations about the new developmentalism in its democratic-inclusive arrangement

Barriers to and enablers of sustainable practices: insights from ethnic minority migrants

Migration from the Global South to Global North is a major feature of contemporary population movements, and provides a lived experiment of the implications of moving from less resource-intensive modes of living towards more resource-intensive ones. Pre-migration practices come together in complex ways post-migration with established norms and infrastructures in destination countries. Here we examine the barriers to and enablers of sustainable practices, synthesising in-depth research from nine different studies in south-eastern Australia in relation to household water use, food growing and transport. The total sample includes 323 migrants from 33 countries. The main barriers include infrastructure and broader patterns of work and society. The main enablers are cultural norms of frugality and preferences for public transport. Barriers and enablers interact in diverse ways. We show that migrants are important contributors to inadvertent sustainabilities, but their contributions may be weakened by infrastructural, structural and cultural barriers. Addressing the diverse capacities of migrants would enhance system change for everyone

Longevity in mice: is stress resistance a common factor?

A positive relationship between stress resistance and longevity has been reported in a multitude of studies in organisms ranging from yeast to mice. Several mouse lines have been discovered or developed that exhibit extended longevities when compared with normal, wild-type mice of the same genetic background. These long-living lines include the Ames dwarf, Snell dwarf, growth hormone receptor knockout (Laron dwarf), IGF-1 receptor heterozygote, Little, α-MUPA knockout, p66shc knockout, FIRKO, mClk-1 heterozygote, thioredoxin transgenic, and most recently the Klotho transgenic mouse. These mice are described in terms of the reported extended lifespans and studies involving resistance to stress. In addition, caloric restriction (CR) and stress resistance are briefly addressed for comparison with genetically altered mice. Although many of the long-living mice have GH/IGF-1/insulin signaling-related alterations and enhanced stress resistance, there are some that exhibit life extension without an obvious link to this hormone pathway. Resistance to oxidative stress is by far the most common system studied in long-living mice, but there is evidence of enhancement of resistance in other systems as well. The differences in stress resistance between long-living mutant and normal mice result from complex interrelationships among pathways that appear to coordinate signals of growth and metabolism, and subsequently result in differences in lifespan
