The epidermal growth factor (EGF) family of receptors (EGFR) is overproduced in estrogen receptor (ER) negative (−) breast cancer cells. An inverse correlation of the level of EGFR and ER is observed between ER− and ER positive (+) breast cancer cells. A comparative study with EGFR-overproducing ER− and low-level producing ER+ breast cancer cells suggests that EGF is a major growth-stimulating factor for ER− cells. An outline of the pathway for the EGF-induced enhanced proliferation of ER− human breast cancer cells is proposed. The transmission of mitogenic signal induced by EGF–EGFR interaction is mediated via activation of nuclear factor κB (NF-κB). The basal level of active NF-κB in ER− cells is elevated by EGF and inhibited by anti-EGFR antibody (EGFR-Ab), thus qualifying EGF as a NF-κB activation factor. NF-κB transactivates the cell-cycle regulatory protein, cyclin D1, which causes increased phosphorylation of retinoblastoma protein, more strongly in ER− cells. An inhibitor of phosphatidylinositol 3 kinase, Ly294–002, blocked this event, suggesting a role of the former in the activation of NF-κB by EGF. Go6976, a well-characterized NF-κB inhibitor, blocked EGF-induced NF-κB activation and up-regulation of cell-cycle regulatory proteins. This low molecular weight compound also caused apoptotic death, predominantly more in ER− cells. Thus Go6976 and similar NF-κB inhibitors are potentially novel low molecular weight therapeutic agents for treatment of ER− breast cancer patients.

Successful neonatal immunization of humans has proven difficult. We have evaluated CpG-containing oligonucleotides as an adjuvant for immunization of young mice (1–14 days old) against hepatitis B virus surface antigen. The protein-alum-CpG formulation, like the DNA vaccine, produced seroconversion of the majority of mice immunized at 3 or 7 days of age, compared with 0–10% with the protein-alum or protein-CpG formulations. All animals, from neonates to adults, immunized with the protein-alum vaccine exhibited strong T helper (Th)2-like responses [predominantly IgG1, weak or absent cytotoxic T lymphocytes (CTL)]. Th2-type responses also were induced in young mice with protein-CpG (in 1-, 3-, and 7-day-old mice) and protein-alum-CpG (in 1- and 3-day-old mice) but immunization carried out at older ages gave mixed Th1/Th2 (Th0) responses. DNA vaccines gave Th0-like responses when administered at 1 and 7 days of age and Th1-like (predominantly IgG2a and CTL) responses with 14-day-old or adult mice. Surprisingly, the protein-alum-CpG formulation was better than the DNA vaccine for percentage of seroconversion, speed of appearance, and peak titer of the antibody response, as well as prevalence and strength of CTL. These findings may have important implications for immunization of human infants.

Volume containing medicinal recipes, medical notes, poetry, and obituaries written by Dr. Moses Appleton (1773-1849). Many of the recipes were copied from medical texts or other publications. His "cure for the dropsy," taken from the New York Herald, contained stale cider, parsley, horseradish, oxymel squills (sea onion in honey), and juniper berries. For diarrhea, he prescribed a blackberry syrup. Several entries indicate Appleton practiced Thomsonian medicine, an alternative system based on use of botanicals. The medical notes include an account of his treatment of a man with smallpox in 1815, and entries on patients he inoculated with cowpox matter. Another entry dated in 1796 provides instructions from the Massachusetts Humane Society for "treatment to be used with persons apparently dead from drowning," which included blowing tobacco smoke in the victim's lungs and applying warm blankets for several hours. Appleton adds a note questioning whether or not the lungs also should be "often artificially inflated." There is additionally a history of prominent physicians dating from ancient Greece.
