Most studies of differential gene-expressions have been conducted between two given conditions. The two-condition experimental (TCE) approach is simple in that all genes detected display a common differential expression pattern responsive to a common two-condition difference. Therefore, the genes that are differentially expressed under the other conditions other than the given two conditions are undetectable with the TCE approach. In order to address the problem, we propose a new approach called multiple-condition experiment (MCE) without replication and develop corresponding statistical methods including inference of pairs of conditions for genes, new t-statistics, and a generalized multiple-testing method for any multiple-testing procedure via a control parameter C. We applied these statistical methods to analyze our real MCE data from breast cancer cell lines and found that 85 percent of gene-expression variations were caused by genotypic effects and genotype-ANAX1 overexpression interactions, which agrees well with our expected results. We also applied our methods to the adenoma dataset of Notterman et al. and identified 93 differentially expressed genes that could not be found in TCE. The MCE approach is a conceptual breakthrough in many aspects: (a) many conditions of interests can be conducted simultaneously; (b) study of association between differential expressions of genes and conditions becomes easy; (c) it can provide more precise information for molecular classification and diagnosis of tumors; (d) it can save lot of experimental resources and time for investigators.^

William C. Moloney MD kept a personal journal, with photographs, for much of his two years in Japan with the Atomic Bomb Casualty Commission. In January of 1986, Dr.Moloney donated his journal, correspondence and diary pages to the Harris County Medical Archive. He died in 1998 at the age of 91. His first contribution was a set of ten reprints representing his work with the ABCC from 1952 to 1954. Dr.Moloney's journal is a fine document, one which will be of great use to historians. It is an important record of personal impressions, thoughts and details of events. The journal gives new insights into the work of the ABCC and into the people who participated in that work. Dr. Moloney wrote in his journal from April 1952 to February 1954. The Korean War was on and there was a great deal of military activity in southern Japan. The collection is open for research. The collection consists of a handwritten journal, loose calendar or notebook pages and some reprints. The journal is in generally fair condition. The paper is slightly acidic and the binding is loose. There are numerous photos glued onto the pages. The collection encompasses the years 1952-1954 and is 0.25 cubic feet (1 box).

Autoimmune diseases are a group of inflammatory conditions in which the body's immune system attacks its own cells. There are over 80 diseases classified as autoimmune disorders, affecting up to 23.5 million Americans. Obesity affects 32.3% of the US adult population, and could also be considered an inflammatory condition, as indicated by the presence of chronic low-grade inflammation. C-reactive protein (CRP) is a marker of inflammation, and is associated with both adiposity and autoimmune inflammation. This study sought to determine the cross-sectional association between obesity and autoimmune diseases in a large, nationally representative population derived from NHANES 2009–10 data, and the role CRP might play in this relationship. Overall, the results determined that individuals with autoimmune disease were 2.11 times more likely to report being overweight than individuals without autoimmune disease and that CRP had a mediating affect on the obesity-autoimmune relationship. ^
