BACKGROUND Macrophage migration inhibitory factor (MIF) is known to be a proinflammatory cytokine and glucocorticoid‐induced immunomodulator as well as a regulator of tumor growth. Although positive and negative effects of MIF on tumor cell growth have been reported, to the authors' knowledge the precise role of MIF in tumorigenesis remains unclear. In the current study the authors assessed expression of MIF protein and mRNA in lung adenocarcinomas with regard to patient prognosis. METHODS Immunohistochemical analysis was performed on tissue specimens surgically obtained from 74 patients with primary lung adenocarcinoma (American Joint Committee on Cancer pathologic Stages I, II, and IIIa). In addition, expression of MIF mRNA in the cancerous tissue was investigated using in situ hybridization. Patient prognosis was evaluated with regard to MIF expression levels and its distribution was analyzed with the Kaplan–Meier method. RESULTS MIF mRNA and MIF protein were observed in the bronchial epithelium, alveolar epithelium, vascular smooth muscle, and alveolar macrophages in the normal lung tissue. In tumor tissue from lung adenocarcinoma specimens, both MIF mRNA and protein were observed at much higher levels than in the normal alveolar epithelium. MIF protein was observed diffusely in the cytoplasm of tumor cells in all tumor specimens examined. MIF protein also was observed in the nuclei of tumor cells from 59 patients (79.7%), whereas it was not observed in the nuclei of tumor cells from 15 patients (20.3%). The patients without nuclear MIF expression had a worse prognosis compared with those patients with MIF expression in the nuclei (P = 0.04). CONCLUSIONS The results of the current study suggest that intracellular MIF distribution predicts patient prognosis in individuals with adenocarcinoma of the lung.

e Rubrivivax gelatinosus is a facultative photoheterotrophic betaproteobacterium living in freshwater ponds, sewage ditches, activated sludge, and food processing wastewater. There have not been many studies on photosynthetic betaproteobacteria. Here we announce the complete genome sequence of the best-studied phototrophic betaproteobacterium, R. gelatinosus IL-144 (NBRC 100245).

This cross sectional study assessed the physical and mental health, health literacy and social support of the uninsured utilizing a free clinic to develop intervention programs and research projects to improve the health of free clinic patients. Free clinics are nonprofit organizations that provide underserved and uninsured individuals access to a broad array of free or low cost healthcare services. English or Spanish speaking patients (N = 187) aged 18 years or older completed a self-administered survey. Physical, mental and oral health, health literacy, and social support were measured using standardized instruments. Eighty-two participants (45 US born and 37 non-US born) chose the English version of the survey (English speakers) while 105 participants (2 US born and 103 non-US born) chose the Spanish version (Spanish speakers). Overall, both the physical and mental health functioning of the participants was lower than that of the US general population. The participants reported being moderately depressed. US-born English speakers reported the poorest physical and mental health while Spanish speakers reported the best physical health and the lowest level of depression. A higher level of health literacy was associated with better physical health functioning, whereas reporting higher social support was associated with better mental health functioning and less severe depression. Because most free clinics have limited resources, developing services and programs that fit free clinics' circumstances are needed. Our study finding indicates that health literacy education, mental health services, and social support are key services needed by free clinic patients to achieve better health.
