Over the past two decades, Shanghai, the largest megacity in China, has been coping with unprecedented growth of its economy and population while overcoming previous underinvestment in the health system by the central and local governments. We study the evolution of Shanghai’s healthcare system by analyzing “Avoidable Mortality” (AM) – deaths amenable to public health and healthcare interventio...

The decrease, since z=1, of the rest-frame UV luminosity density is related to global changes in morphology, color and emission lines properties of galaxies. This is apparently followed by a similar decrease of the rest-frame IR luminosity density. I discuss the relative contribution from the different galaxy morphological types to the observed evolution. The main contributors are compact galax...

Evaluation of population-level impacts is critical to credible ecological risk assessments. In this study, a predictive model was developed to translate changes in fecundity of the fathead minnow (Pimephales promelas) in a short-term laboratory toxicity test to alterations in population growth rate. The model uniquely combines a Leslie population projection matrix and the logistic equation. App...

BACKGROUND Worsening of pulmonary diseases is associated with a decrease in oxygen saturation (SpO2). Such a decrease in SpO2 and associated factors has not been previously evaluated in a general adult population. AIM We sought to describe SpO2 in a sample of adults, at baseline and after 6.3 years, to determine whether factors predicting low SpO2 in a cross-sectional study were also associat...

A phenomenon that strongly influences the demography of small introduced populations and thereby potentially their genetic diversity is the demographic Allee effect, a reduction in population growth rates at small population sizes. We take a stochastic modeling approach to investigate levels of genetic diversity in populations that successfully overcame either a strong Allee effect, in which po...

Background: Type-1 diabetes (T1D) is an autoimmune disease in which T lymphocytes destroy insulin-producing β-cells. Control of self-reactive T lymphocytes and recovery of diabetic injury is the end point of T1D. Objective: To investigate generation of tolerogenic dendritic cells (tolDCs) as an innovative method of diabetes therapy. Methods: Lentivirus vector production was achieved by GIPZ mou...
