Memory Element and Data Security Platforms Using Self-Sufficient Molecular Assembly Through Concentration Reliant Photo-Switching: A Latent Trait of Semicarbazone Schiff Base.

Logic operations at the molecular level are anticipated to play key role in data processing and storage in the future. However, most of these chemical systems rely on foreign chemical inputs. In contrast, opto-chemical logic devices are simpler to implement due to the ease of optical changes compared to pure chemical ones.

Breast Cancer Risk From Modifiable and Nonmodifiable Risk Factors Among White Women in the United States.

Importance: An improved model for risk stratification can be useful for guiding public health strategies of breast cancer prevention.

Objective: To evaluate combined risk stratification utility of common low penetrant single nucleotide polymorphisms (SNPs) and epidemiologic risk factors.

Design, Setting, And Participants: Using a total of 17 171 cases and 19 862 controls sampled from the Breast and Prostate Cancer Cohort Consortium (BPC3) and 5879 women participating in the 2010 National Health Interview Survey, a model for predicting absolute risk of breast cancer was developed combining information on individual level data on epidemiologic risk factors and 24 genotyped SNPs from prospective cohort studies, published estimate of odds ratios for 68 additional SNPs, population incidence rate from the National Cancer Institute-Surveillance, Epidemiology, and End Results Program cancer registry and data on risk factor distribution from nationally representative health survey.
