Kinetic Theory of Self-Propelled Particles with Nematic Alignment.

We present the results from kinetic theory for a system of self-propelled particles with alignment interactions of higher-order symmetry, particularly nematic ones. To this end, we use the Landau equation approach, a systematic approximation to the BBGKY hierarchy for small effective couplings. Our calculations are presented in a pedagogical way with the explicit goal of serving as a tutorial from a physicists' perspective into applying kinetic theory ideas beyond mean-field to active matter systems with essentially no prerequisites and yield predictions without free parameters that are in quantitative agreement with direct agent-based simulations.

Cancer Incidence among Marines and Navy Personnel and Civilian Workers Exposed to Industrial Solvents in Drinking Water at US Marine Corps Base Camp Lejeune: A Cohort Study.

Background: Drinking water at US Marine Corps Base Camp Lejeune, North Carolina, was contaminated with trichloroethylene and other industrial solvents from 1953 to 1985.

Methods: A cohort cancer incidence study was conducted of Marines/Navy personnel who began service and were stationed at Camp Lejeune () or Camp Pendleton, California () between 1975 and 1985 and civilian workers employed at Camp Lejeune () or Camp Pendleton () between October 1972 and December 1985. Camp Pendleton's drinking water was not contaminated with industrial solvents.

Unraveling the metastasis-preventing effect of miR-200c in vitro and in vivo.

Advanced breast cancer, as well as ineffective treatments leading to surviving cancer cells, can result in the dissemination of these malignant cells from the primary tumor to distant organs. Recent research has shown that microRNA 200c (miR-200c) can hamper certain steps of the invasion-metastasis cascade. However, it is still unclear whether miR-200c expression alone is sufficient to prevent breast cancer cells from metastasis formation.
