Narratives of Food Insecurity in Tippecanoe County,Indiana: Economic Constraints in Local Meanings of Hunger

Food insecurity and its most extreme form, hunger, have increased exponentially in the United States since 2006. This essay seeks to contribute to our understanding of hunger by attending to the context of the financial crisis as an organizing frame for understanding local meanings of hunger. Within a broader framework of the culture-centered approach (CCA) that works to identify and develop locally rooted solutions to food insecurity, we describe through locally grounded stories of food insecurity the financial climate where large percentages of U.S. households have been cast into poverty because of the crash of an unregulated economy. These local understandings of hunger in the context of the economy offer entry points for organizing a food-insecure coalition that seeks to address the stigma around food insecurity.     

Space within the Scientific Discourse for the Voice of the Other? Expressions of Community Voice in the Scientific Discourse of Community-Based Participatory Research

ABSTRACT

Community-based participatory research (CBPR) has captured public health attention and support because it is positioned as an approach that involves researchers and communities as equitable partners in addressing health disparities. However, it is unknown the extent to which CBPR creates a participatory space in the scientific discourse to signal “community voice,” which we define as textual expression of community-centered perspectives on collective roles, interests, and worldviews. In this study, we utilized the culture-centered approach to examine the expression of community voice in the abstracts and public health relevance statements of 253 extramural CBPR projects in the U.S. that received funding from the National Institute of Health and Centers for Disease Control and Prevention in 2009. We found that project abstracts and public health relevance statements contain four textual domains, or potential sites of contest to signal the articulation of community agency and voice within the CBPR projects. These domains include: 1) the rationale for the community health issue, 2) the roles of community partners, 3) community-centered outcomes of the partnership, and 4) elements of participatory research process. The degree of culture-centeredness of the texts is suggested in the extent to which articulations of community agency and voice are signaled across the four domains. We conclude that the dynamics of CBPR may shape culture-centered expressions of problem identification, solution configuration, structural transformations, reflexivity, values, and agency in the project abstracts and public health relevance statements.     

Nanoparticles and Nanostructured Surface Fabrication for Innovative Cranial and Maxillofacial Surgery

A novel strategy to improve the success of soft and hard tissue integration of titanium implants is the use of nanoparticles coatings made from basically any type of biocompatible substance, which can advantageously enhance the properties of the material, as compared to its similar bulk material. So, most of the physical methods approaches involve the compaction of nanoparticles versus micron-level particles to yield surfaces with nanoscale grain boundaries, simultaneously preserving the chemistry of the surface among different topographies. At the same time, nanoparticles have been known as one of the most effective antibacterial agents and can be used as effective growth inhibitors of various microorganisms as an alternative to antibiotics. In this paper, based on literature research, we present a comprehensive review of the mechanical, physical, and chemical methods for creating nano-structured titanium surfaces along with the main nanoparticles used for the surface modification of titanium implants, the fabrication methods, their main features, and the purpose of use. We also present two patented solutions which involve nanoparticles to be used in cranioplasty, i.e., a cranial endoprosthesis with a sliding system to repair the traumatic defects of the skull, and a cranial implant based on titanium mesh with osteointegrating structures and functional nanoparticles. The main outcomes of the patented solutions are: (a) a novel geometry of the implant that allow both flexible adaptation of the implant to the specific anatomy of the patient and the promotion of regeneration of the bone tissue; (b) porous structure and favorable geometry for the absorption of impregnated active substances and cells proliferation; (c) the new implant model fit 100% on the structure of the cranial defect without inducing mechanical stress; (d) allows all kinds of radiological examinations and rapid osteointegration, along with the patient recover in a shorter time.

Expression Analysis of Survivin and XIAP in Gallbladder Cancer: a Case-control Study in Indo-Gangetic Plain

Purpose

Gallbladder cancer is a highly mortal disease with poor prognosis because of late presentation of disease. Survivin and X-linked inhibitor of apoptosis (XIAP) are one of the two important members of inhibitors of apoptosis. Thus, this study aimed to look at the expression of Survivin and XIAP in gallbladder cancer patients.

Methods

Survivin and XIAP expression were investigated in tissues of gallbladder cancer patients (40 cases) and compared with cholelithiasis as control (40 cases) by using immunohistochemistry. Their expression was correlated with clinicopathological parameters.

Results

Significantly higher (p < 0.05), Survivin protein was expressed in gallbladder cancer (n = 67.5%) than control (n = 35%). But it did not show any significant association with any of the clinicopathological parameter while XIAP was not expressed in the GBC patients (p > 0.05).

Conclusion

Overexpression of Survivin in gallbladder cancer suggests its possible role and association with poor prognosis. But XIAP has not been found to be associated with gallbladder carcinogenesis.
