Partnering with communities is a critical aspect of contemporary health promotion. Linkages between universities and communities are particularly significant, given the prominence of academic institutions in channeling grants. This article describes the collaboration between a school of public health and several community-based organizations on a maternal and infant health grant project. The partnership serves as a model for ways in which a university and community organizations can interrelate and interact. Central lessons include the significance of sharing values and goals, the benefit of drawing on the different strengths of each partner, the gap created by the university's institutional focus on research rather than service and advocacy, and the strains created by power inequities and distribution of funds. A key element of the partnership's success is the emphasis on capacity building and colearning. The project demonstrates the potential of employing community-academic partnerships as a valuable mechanism for implementing community-based health promotion programs.
This double-blind, randomized, crossover study investigated whether acute cacao polyphenol (CP) ingestion attenuates neuromuscular fatigue in 19 healthy young male adults. After consuming CP or placebo, participants performed sustained isometric ankle dorsiflexion at 25% of maximal voluntary isometric contraction (MVIC) torque until task failure. Neuromuscular function (MVIC torque, voluntary activation [VA%], doublet torque) and electromyographic activity were assessed before, immediately after, and during recovery (1 and 5 min). Salivary chromogranin A and α-amylase were measured at baseline and 1 min post-task. Only VA% and chromogranin A showed significant condition × time interactions (p = 0.027-0.039). VA% significantly decreased from before to immediately after the task and 1 min post-task in both conditions (p ≤ 0.002), with significantly higher values in the CP condition than in placebo immediately after and 1 min post-task (p ≤ 0.037). Chromogranin A significantly increased from baseline to 1 min post-task in the placebo condition (p < 0.001) but not in the CP condition (p = 0.083). These findings suggest that acute CP ingestion attenuates the decline in central motor drive and autonomic stress responses following strenuous exercise, without altering performance or peripheral recovery, supporting its potential as a nutritional strategy for modulating central fatigue.

The biological and physical environment of the planet is changing at an unprecedented rate as a result of human activity, and these changes may have an enormous impact on human health. One of the goals of human development is to protect health in the face of rapid environmental change, but we often fail to do this. The aim in this paper is to distinguish between socioeconomic aspects of development that are likely to be protective and those that are likely to increase vulnerability (the capacity for loss resulting from environmental change). Examples include climate change in the Pacific. We conclude that protecting human health in a changing world requires us to take steps to minimize harmful change wherever possible, and at the same time to be prepared for surprises. The goals of mitigation (reducing or preventing change) and adaptation (response to change) are not mutually exclusive. In fact, steps to make populations more resilient in the face of change are often similar to those that are needed to lighten the load on the environment. We need social policies that convert economic growth into human development. Wider application of sustainable development concepts is part of the solution. In particular, there is a need to promote health as an essential asset of poor and vulnerable populations. It is their key to productivity and to surviving shocks; it is also the key to achieving broader development goals such as universal education. For these reasons it is in the interests of all sectors--economic, social and environmental--to play their particular roles in protecting and improving health.
Evaluation of the height from which human fell from his/her tissue and organ injuries is discussed. The authors of available publications paid the principal attention to estimation of the height from which the victim fell without consideration for the kinetic energy of the body, which depends not only on the height from which the victim fell, but on his/her body weight as well. Primary external and primary internal injuries are distinguished, which are determined by the area of contusion during landing; secondary contact injuries which form during inertial movement of the body after the first contusion, and injuries due to negative acceleration during contusion when landing (so-called signs of total body concussion) are also distinguished. The totality of all listed injuries helps estimate the total kinetic energy at the moment of contusion and determine the height of falling, with due consideration for anthropometric characteristics of the victim.

OBJECTIVE: To reduce the frequency of administration of tamoxifen citrate so as to improve its bioavailability and patients' compliance. METHODS: HPMC(K4M) was employed as major retarded-release controller. The wetting granulation and directly compressing method was used to produce the sustained release tablet. Then the in vitro release profile was applied as main criteria to evaluate six formulations according to the variation of HPMC(K4M) amount. The concentration of tamoxifen citrate was measured by UV spectrometry. Finally the releasing characteristics of sustained release and conventional tablets were compared to clarify the sustained effect of the former. RESULT: At 278 nm there was no interaction between tamoxifen citrate and the recipients so that it was adopted as the wavelength of determination. The recovery efficiency of this method ranged from 95%-105%. The final formulation could release 86.40% of its loading amount in 12 h and its releasing profile fitted the Zero-order equation well. The percentages of accumulative release in 1 h were 76.81% and 7.08% for sustained release tablet and conventional tablet respectively. CONCLUSION: The sustained release tablet of tamoxifen citrate could demonstrate a continuous and stable releasing profile and last for over 12 h. It has significant retarded effect in comparison with the conventional one and could be a new choice of regimen in its clinical application.
There are arguments for and against organic agriculture. The paper looks at the impact of changes and development, the need for sustainable development, organic farming as a viable alternative, organic certification and concluding thoughts on why organic farming makes sense. To go organic does not necessarily mean that organic products are totally free of chemical pesticides but they have a lower pesticide residue. Organic certification, a process guarantee not a product guarantee, becomes necessary if a farmer has to sell organic food products locally (to tourists) or export overseas. For Pacific organic producers, the biggest obstacle lies with certification costs and initial investments in research and extension to educate consumers and farmers about organic agriculture organic methods.
